A concha nasal inferior e uma lamina fina chronic gastritis raw vegetables purchase sucralfate paypal, curva em sua borda livre que se liga superficie nasal da maxila e na lamina perpendicular do osso palatino gastritis diet bland order generic sucralfate. Embriologicamente seu aparecimento e resultado de uma infiltracao endocondral e ossea da regiao maxiloturbinal gastritis diet generic 1000mg sucralfate free shipping. Tres proeminencias projetam-se da borda livre da concha inferior: a mais anterior e o processo lacrimal gastritis images order 1000mg sucralfate visa, o qual liga-se ao osso lacrimal e ao ostio do ducto nasolacrimal (Hasnerfis valve) gastritis pepto bismol order sucralfate 1000 mg mastercard. A mais mediana gastritis symptoms fatigue discount sucralfate 1000 mg amex, o processo etmoidal da concha inferior, liga-se ao processo uncinado e separa a fontanela anterior da posterior. A mais posterior, o processo maxilar, forma parte da parede medial do seio maxilar. A concha nasal media tem uma porcao vertical em sua borda anterior livre que pode ser fina ou proeminente e ocasionalmente lobulada. Sua margem posterior e ligada a parede lateral e a lamina perpendicular do osso palatino. A concha media pode estar pneumatizada tanto em sua porcao anterior como em sua porcao posterior, denominando-se concha bolhosa. A concha nasal superior localiza-se na regiao mais superior da fossa nasal e no seu meato drenam as celulas etmoidais posteriores e seio 4 esfenoidal. O ramo maxilar (V2) do nervo trigemio emite o nervo infra-orbitario, que inerva a piramide nasal. Uma grande quantidade de ramos mediais do nervo maxilar ascende da fossa pterigopalatina e penetra na cavidade nasal atraves do foramen esfenopalatino, enviando ramos para as paredes septal e lateral da cavidade nasal. Os ramos da parede lateral formam varios pequenos nervos na mucosa, denominados nasais postero-laterais. Portanto, a inervacao da parte posterior (e maior) da cavidade nasal e dependente do nervo maxilar principalmente. A divisao oftalmica (V1) do nervo trigemio envia varios ramos nasais constituindo o nervo nasociliar. Este atravessa a porcao medial da orbita originando os nervos etmoidais anterior e posterior, que inervam a mucosa das celulas etmoidais. O etmoidal posterior inerva uma pequena area de mucosa proxima a concha superior na parede lateral e uma area correspondente no septo nasal. O nervo etmoidal anterior envia ramos para a mucosa do septo e da parede lateral, acompanhando a superficie posterior do osso nasal como o nervo nasal interno, ate alcancar a cartilagem nasal lateral superior. Passa, entao, entre esta cartilagem e o osso nasal, ocupando a superficie como nervo nasal externo, inervando a pele do dorso e do apice nasal. Inervacao Parassimpatica: A partir do ganglio geniculado do nervo facial, origina-se o nervo petroso maior que distribui fibras pre ganglionares para as glandulas da mucosa nasal. Este nervo se junta as fibras simpaticas no canal pterigoideo, sendo conhecido como nervo do canal pterigoideo ou nervo vidiano. Apos sinapses no ganglio pterigopalatino, fibras pos ganglionares seguem medialmente atraves do foramen esfenopalatino e junto com os ramos esfenopalatinos do nervo maxilar, atingem as paredes septal e lateral da cavidade nasal. Os nervos nasal lateral posterior e nasopalatino tambem contem fibras parassimpaticas para as glandulas da mucosa nasal. Inervacao Simpatica: Fibras nervosas do simpatico atraves do nervo petroso profundo unem-se ao petroso maior para formar o nervo vidiano, como ja mencionado. Quando as fibras pos ganglionares alcancam a fossa pterigopalatina, elas nao fazem sinapses no ganglio pterigopalatino, pois, como se sabe, este e um ganglio parassimpatico. A distribuicao destas fibras nao e bem conhecida, mas muitas se dirigem para as fibras vasomotoras de vasos sanguineos 6 localizados nas mucosas oral e nasal, via ramos do nervo maxilar. Lesoes traumaticas dos centros de crescimento do nariz e da cartilagem septal durante a infancia ou mesmo durante o nascimento (uso inadequado de forcipe, por exemplo) sao eventos que podem passar despercebidos, mas que com o crescimento podem se tornar sintomaticos. Os desvios originados de traumas faciais ocorrem geralmente na parte anterior da cartilagem quadrangular do septo, enquanto a regiao compreendida pela juncao da cartilagem quadrangular do septo com a lamina perpendicular do etmoide e com o vomer detem o maior numero dos desvios nao-traumaticos ou casos de traumas discretos na infancia, onde ocorreu 6 6 apenas luxacao da cartilagem, havendo perda do apoio da canaleta do vomer. Alem da obstrucao, o desvio septal pode tambem estar associado a diminuicao do 10,11 transporte mucociliar em ambos os lados do desvio septal, obstrucao do ostio dos seios (eventualmente levando a sinusopatia) e ao desenvolvimento de epistaxes de repeticao, geralmente por cristas septais pronunciados inferiormente, que concentram o fluxo aereo em um local, promovendo ressecamento, formacao de crostas e epistaxes. A simples identificacao de um desvio septal nao significa que ele deva ser corrigido, a nao 3 ser que exista correlacao com os achados clinicos do paciente. O desvio septal esta mais 4 associado como causa de obstrucao nos seguintes casos: 1. A obstrucao teve inicio apos trauma ou no final da segunda decada de vida, (desproporcao entre o crescimento osseo e cartilaginoso torna-se mais evidente). Desvios simples: e o desvio do septo osteocartilaginoso para um lado, sem luxacao da articulacao condrovomeriana e sem formacao de crista ou esporao. Crista: decorre da luxacao da articulacao condrovomeriana, projetando na luz da fossa nasal uma formacao em angulo diedro, constituido pelo plano cartilaginoso (da cartilagem septal) e plano osseo do vomer, podendo iniciar-se na espinha nasal e alongar-se ate areas posteriores do septo(Fig. Esporao: projecao osteocartilaginosa pontiaguda formada na convergencia da cartilagem septal, do vomer e da lamina perpendicular do etmoide na parte posterior do septo (Fig. Desvio misto: e o tipo mais comum de alteracao do septo, constituindo-se em combinacoes dos tipos descritos acima (Fig 5D). A avaliacao inicial complementada principalmente pela Tomografia Computadorizada e praticamente suficiente para fazer a indicacao cirurgica. A resistencia nasal deve descrever medicoes consecutivas de fluxo aereo e pressao transnasal (Rn = fi P/ V) e ser expressa em Pa/cm3/s (Rn = resistencia nasal, fi P = diferenca de pressao entre a nasofaringe e a atmosfera ou entre a nasofaringe e o interior da mascara facial utilizada, V = fluxo aereo, Pa = Pascal). O grafico de pressao transnasal versus fluxo durante a respiracao nasal e uma curva sigmoide, e a razao entre as coordenadas retangulares (fi P/ V) define a resistencia nasal em cada ponto ou pontos escolhidos da curva. Varios metodos podem ser utilizados para a afericao da pressao e do fluxo aereo transnasal. Estes podem ser combinados de varias formas: Pressao transnasal: 1) Rinomanometria ativa anterior pressao e determinada por um tubo fino adaptado no vestibulo nasal, enquanto o paciente respira pela fossa nasal contralateral. O paciente respira pela cavidade nasal nao ocluida e a pressao pos-nasal e conduzida pelo lado ocluido para o tubo gravador de pressao. Com os labios fechados ao redor do tubo, o paciente respira pelo nariz e as pressoes entre as narinas e a orofaringe podem ser assim determinadas. Neste metodo o paciente pode tambem respirar simultaneamente pelas duas narinas e, se necessario, o operador pode ocluir uma das narinas e medir, assim a pressao apenas do lado desejado. A rinomanometria posterior e vantajosa nos casos em que se deseja incluir a avaliacao da influencia da adenoide na resistencia nasal, sendo o metodo de escolha em criancas, porem requer maior colaboracao. A rinomanometria anterior requer minima colaboracao do paciente e e utilizada para pacientes adultos. Tambem pode ser realizada por meio de uma mascara facial ou ainda por meio de pletismografia de corpo inteiro (que determina o volume de gas toracico e a resistencia das vias aereas). Assim como os metodos de afericao da pressao, estes metodos tambem oferecem vantagens e desvantagens. As olivas do tipo bico de garrafa, comumente utilizadas na rinomanometria ativa anterior, correm o risco de deformar a area da valvula nasal e induzir resistencia nasal menor que a real. As mascaras faciais tambem sao propensas a deformar a area da valvula nasal ao exercer pressao demasiada nos tecidos perinasais da face. O uso do pletismografo de corpo inteiro oferece como principal vantagem a possibilidade de avaliacao da area da valvula nasal sem risco de distorcao, deixando a face exposta ao tecnico. A desvantagem e que pacientes claustrofobicos podem resistir ao exame e tambem ha necessidade de equipamento de maior complexidade. Os valores normais da resistencia nasal total e unilateral variam muito na literatura, apesar disso, consideram-se anormais: a) Resistencia nasal total (fossas nasais direita e esquerda combinadas) em condicoes basais superiores a 3 cm/H2O/L/s ou 0,3 Pa/cm3/s. Representacao rinomanometrica da pressao transnasal versus fluxo aereo durante a respiracao de repouso em uma cavidade nasal normal e em uma cavidade nasal bem obstruida. O metodo e baseado na analise de ondas sonoras refletidas pelas cavidades nasais diante de um estimulo sonoro. Ondas sonoras incidentes e refletidas sao detectadas por um microfone, e os sinais, conduzidos para um programa de computador, que gera um grafico de areas em funcao da distancia da narina. As principais caracteristicas da rinometria acustica incluem a alta reprodutibilidade e a rapidez com que o grafico de area em funcao da distancia da narina e gerado. Essas caracteristicas tem sido muito exploradas na avaliacao da fisiologia nasal, mais especificamente na analise do comportamento da mucosa nasal ao longo do tempo, em condicoes basais e diante de estimulos diversos (por exemplo, frio, exercicio, postura, medicamentos). Do ponto de vista clinico, utiliza se a tecnica principalmente para substanciar os achados da rinoscopia e para o seguimento objetivo da resposta aos tratamentos clinicos e/ou cirurgicos empregados. O sistema basico consiste em um tubo condutor de som ao qual e acoplado, na porcao proximal ao individuo em teste, um microfone e na porcao distal ou final, um alto-falante. Ao acionar o sistema, ondas sonoras sao geradas pelo alto-falante, percorrem o tubo de som e entram na cavidade nasal, onde parte dessa energia sonora e refletida para o tubo condutor de som. O programa permite calcular a area de seccao transversal em qualquer ponto da cavidade nasal a partir da narina. Testa-se o paciente em condicoes basais (sem intervencao nasal) e 5 a 10 min apos aplicacao de descongestionante topico. A rinometria acustica determina a geometria estatica do lumen da area da valvula nasal e as alteracoes provocadas pela aplicacao de descongestionante topico ou do dilatador nasal externo. Outra importante vantagem da tecnica e dispensar maior colaboracao dos pacientes, necessitando de poucos segundos para ser realizada. Cavidades nasais normais: curvas habituais de area em funcao da distancia da narina. Notar que a aplicacao do dilatador nasal externo provocou aumento da area transversal nas duas constricoes da area da valvula nasal (seta curva superior). Notar que a aplicacao do descongestionante topico provocou aumento da area transversal a partir da segunda constricao da area da valvula nasal (seta curva superior). Indicacoes: As septoplastias para correcao dos desvios septais devem ser indicadas quando o desvio determina a obstrucao nasal, evidenciada pelas queixas clinicas 6 e pelo exame do paciente. Outra indicacao de septoplastia, embora controversa, e a cefaleia rinogenica, tambem conhecida por Sluders midfacial neuralgia. Estes pacientes apresentam cefaleia recorrente, descrita normalmente como sensacao de pressao ou dor penetrante sobre o dorso nasal. Inicia-se nos periodos de congestao nasal ou durante a fase congesta do ciclo nasal, podendo relacionar-se a mudancas de tempo ou posicao. Frequentemente os pacientes relatam alivio da sintomatologia apos uso de descongestionantes. A dor e mais comumente unilateral e localizada sobre a area de contato, mas eventualmente pode ser bilateral ou frontal. O exame para ser sugestivo desta etiologia deve mostrar pelo menos um ponto significante de contato mucoso. Entre eles podemos destacar o contato entre corneto medio e o septo nasal desviado (muitas vezes a concha media e bolhosa). O objetivo da cirurgia e remover o ponto de contato (trigger zone), promovendo o controle da dor. Nos casos em que o diagnostico nao possa ser confirmado (area de contato presente), a cirurgia nao deve ser realizada nos pacientes que apresentarem cefaleia isolada sem previa avaliacao neurologica. Pacientes com queixa de cefaleia frontal nao associada a obstrucao nasal, nao se beneficiam do procedimento. Estudos analiticos mostram que pacientes de meia idade com obstrucao nasal, particularmente aqueles com sintomas noturnos de rinite, tem chances 39 significativamente maiores de apresentarem roncos habituais. Estudos mostram que a correcao das deformidades nasais pode melhorar moderadamente a duracao, intensidade e frequencia dos roncos. Mais o recentemente a remocao do septo osseo, como via de entrada para o 2 cirurgiao 13 em campo, foi descrita para a resseccao endoscopica de nasoangiofibromas. Tecnicas Cirurgicas: Antes de se passar a descricao cirurgica propriamente dita, vale a pena diferenciar entre dois termos muito utilizados: resseccao submucosa do septo nasal: corrige o desvio septal apenas atraves da remocao de porcoes osseas e cartilaginosas; septoplastia nasal (mais contemporaneo): corrige os desvios atraves do reposicionamento da cartilagem desviada e remocao minima de osso e cartilagem. Atualmente, a cirurgia septal incorpora ambas tecnicas, o reposicionamento da cartilagem septal e resseccao parcimoniosa dos componentes septais nao envolvidos na sustentacao nasal (fala-se atualmente em taticas cirurgicas, onde cada cirurgiao aproveita partes de varias tecnicas e de outros cirurgioes para assim obter melhores resultados). Com o paciente sob anestesia geral, procede-se a infiltracao do septo nasal com solucao de lidocaina a 2% e 1:40. A cirurgia comeca com a incisao na mucosa ao nivel da juncao septo columelar nos dois lados, ou em apenas em um deles (hemitransfixante). Essa incisao deve expor a parte caudal do septo, para isso deve se estender desde a borda superior do septo ate a espinha nasal, inferiormente. A identificacao do plano subpericondral e o procedimento mais importante de toda a cirurgia e e fundamental para o seu sucesso. Um aspirador-descolador e usado para elevar o mucopericondrio do septo, deslizando contra a cartilagem atraves de movimentos 6 sucessivos para cima e para baixo (figura 9). Descolamento subpericondral (Atlas of Head Neck Surgery Otolaryngology Cap 165) O plano correto de descolamento (subpericondral) e diretamente sobre a cartilagem septal, levantando-se o pericondrio (e um plano avascular e com coloracao tipica branco-acinzentada, de facil descolamento). O plano correto na 13 parte ossea e, da mesma forma, diretamente sobre o osso e abaixo do periosteo. A camada mucoperiosteal nao e perfeitamente contigua com a de mucopericondrio, portanto o descolamento nessa area de transicao e por vezes trabalhosa e perfuracoes da mucosa sao comuns, devendo-se redobrar o cuidado a este nivel. Conforme o descolamento progride, procura-se usar especulos nasais mais longos, inserindo-os entre o flap descolado e o septo, mantendo-se sempre visao direta. Quando os flaps estao descolados satisfatoriamente dos dois lados, o especulo e entao inserido entre os flaps e a cartilagem, o que propicia tanto a analise precisa das caracteristicas do desvio, quanto a protecao dos flaps durante a resseccao septal. Apos a correcao do desvio cartilaginoso, pode-se visualizar os desvios osseos (lamina perpendicular do etmoide e vomer), que sao retirados atraves de instrumentos como o Jansen ou Brunnings. Deve-se salientar que os fragmentos cartilaginosos e principalmente osseos nunca devem ser retirados pelo mecanismo de avulsao e sim atraves de torcao ate que se produza a fratura, para entao serem delicadamente retirados. Isso e especialmente importante na area proxima a lamina perpendicular do etmoide, a fim de evitar fratura ou avulsao da placa cribiforme, podendo levar a fistula liquorica. Nos desvios septais anteriores, o septo normalmente repousa em um dos lados, levando a obstrucao. Trabalhando-se no plano sub-mucopericondral, tenta se um enfraquecimento (shaving, ou seja, raspando a cartilagem com uma lamina de bisturi) da porcao desviada a fim de quebrar sua memoria e faze-la voltar a linha media.

Evaluation of thoracic dimensions Several skeletal dysplasias are associated with a small thorax gastritis diet vegan discount sucralfate online visa, and chest restriction leads to hcg diet gastritis purchase discount sucralfate on line pulmonary hypoplasia gastritis kod pasa purchase sucralfate, which is the common cause of death in these conditions gastritis symptoms chronic buy sucralfate 1000 mg visa. The appropriateness of thoracic dimensions can be assessed by measuring the thoracic circumference at the level of the four-chamber view of the heart and examining the thoracic-to-abdominal circumference ratio gastritis diet sucralfate 1000mg low cost, the thoracic-to-head circumference ratio gastritis treatment dogs buy genuine sucralfate, or the thoracic-to-cardiac circumference ratio. The term derives from the Greek, meaning death-bearing and the characteristic features are severe shortening of the limbs, narrow thorax, normal trunk length and large head with prominent forehead. Achondrogenesis this is a lethal skeletal dysplasia with a birth prevalence of about 1 in 40 000. In achondrogenesis type I, which is autosomal recessive, there is poor mineralization of both the skull and vertebral bodies as well as rib fractures. Ultrasonography in the second and third trimesters may demonstrate fractures of long bones. Prenatally, limb shortening and typical facis usually become apparent only after 22 weeks of gestation. JarchoLevin syndrome this is a heterogeneous disorder, characterized by vertebral and rib abnormalities (misalignment of the cervical spine and ribs). Another autosomal recessive and an autosomal dominant type are associated with a short stature and are compatible with survival to adult life but with some degree of physical disability. There is a variable phenotypic expression and, consequently, the prognosis varies from neonatal death, due to pulmonary hypoplasia, to normal survival. Short limb polydactyly syndromes this group of lethal disorders is characterized by short limbs, narrow thorax and postaxial polydactyly. Associated anomalies are frequently found, including congenital heart disease, polycystic kidneys, and intestinal atresia. In general, limb deficiency of the upper extremity is an isolated anomaly, whereas congenital amputation of the leg or bilateral amputations or reductions of all limbs are usually part of a genetic syndrome. There is an association between chorion villous sampling before 10 weeks of gestation and transverse limb defects. This is characterized by strict demarcation of the skin lesions to one side of the mid-line and limb deficiencies, which are unilateral, varying from hypoplasia of phalanges to complete absence of an extremity. The condition is also associated with heart defects and unilateral hydronephrosis or renal agenesis. Femoral hypoplasiaunusual facies syndrome, which is sporadic, consists of bilateral femoral hypoplasia and facial defects, including short nose with broad tip, long philtrum, micrognathia and cleft palate. Postaxial polydactyly (the most common form) occurs on the ulnar side of the hand and fibular side of the foot. Preaxial polydactyly is present on the radial side of the hand and the tibial side of the foot. This sequence includes congenital lethal arthrogryposis, multiple pterygium and PenaShokeir syndromes. The condition is commonly associated with polyhydramnios (usually after 25 weeks), narrow chest, micrognathia and nuchal edema (or increased nuchal translucency at 1013+6 weeks). Trisomy 21 Trisomy 21 is associated with a tendency towards brachycephaly, mild ventriculomegaly, flattening of the face, nuchal edema, atrioventricular septal defects, duodenal atresia and echogenic bowel, mild hydronephrosis, shortening of the limbs, sandal gap and clinodactyly or mid-phalanx hypoplasia of the fifth finger. Trisomy 13 In trisomy 13, common defects include holoprosencephaly and associated facial abnormalities, microcephaly, cardiac and renal abnormalities (often enlarged and echogenic kidneys), exomphalos and postaxial polydactyly. Types of abnormalities the following table describes the common chromosomal abnormalities in the presence of various sonographically detected defects. It is therefore recommended that, when an abnormality/marker is detected at routine ultrasound examination, a thorough check is made for the other features of the chromosomal defect(s) known to be associated with that marker; should additional abnormalities be identified, the risk is dramatically increased. The prevalence of these defects is low and therefore the cost implications are small. Examples of these defects include hydrocephalus, holoprosencephaly, multicystic renal dysplasia and severe hydrops. In the case of isolated neural tube defects, there is controversy as to whether the risk for chromosomal defects is increased. If the defect is potentially correctable by intrauterine or postnatal surgery, it may be logical to exclude an underlying chromosomal abnormality, especially because for many of these conditions the usual abnormality is trisomy 18 or 13. Minor defects or markers For apparently isolated abnormalities, there are large differences in the reported incidence of associated chromosomal defects. Since the incidence of chromosomal defects is associated with maternal age, it is possible that the wide range of results reported in the various studies is the mere consequence of differences in the maternal age distribution of the populations examined. Nuchal edema or fold more than 6 mm this is the second-trimester form of nuchal translucency. For isolated nuchal edema, the risk for trisomy 21 may be ten-times the background risk. On the basis of existing studies, short femur is found four-times as commonly in trisomy 21 fetuses compared to normal fetuses. However, they are sometimes associated with cardiac defects and chromosomal abnormalities. For isolated hyperechogenic foci, the risk for trisomy 21 may be three-times the background risk. When other defects are present, there is a high risk of chromosomal defects, usually trisomy 18 but occasionally trisomy 21. When the sonographic diagnosis is uncertain, fetal tissue biopsy may be necessary to obtain a histological diagnosis. Etiology and mechanisms of carcinogenesis Developmental errors during embryonic and fetal maturation may result in embryonic tumors. When any of this developmentally abnormal tissue is present at birth, it is inferred that the cells failed to mature, migrate or differentiate properly during intrauterine life. A genetic model of carcinogenesis has also been introduced in an attempt to clarify the pathogenesis and behavioral peculiarities of certain embryonic tumors. According to this hypothesis, embryonal neoplasms arise as a result of two mutational events in the genome. The first mutation is prezygotic in familial cases and postzygotic in non-familial; the second mutation is always postzygotic. Examples include congenital neuroblastomas and hepatoblastomas in the first year of life, and congenital and infantile fibromatosis, and sacrococcygeal teratomas in the first few months of life. The factors responsible for this oncogenic period of grace, which starts in utero and extends through the first few months of extrauterine life, are uncertain. Probably, there is simultaneous or sequential cellular and tissue reaction to specific injurious agents. It is postulated that the anomalous tissues harbor latent oncogenes which, under certain environmental conditions, are activated, resulting in malignant transformation of a tumor. Tumor-specific signs include pathological changes within the tumor mass (calcifications, liquefaction, organ edema, internal bleeding, neovascularization and rapid changes in size and texture). Examples may vary from severe cases of bladder exstrophy (where the protruding bladder mass appears as a solid tumor-like structure), to rare cases of fetal scrotal inguinal hernia (where bowel loops occupy the scrotum, appearing as huge masses). Hydrocephalus is frequently associated with brain tumors and may be the presenting sign. The limited experience with the other neoplasms in prenatal diagnosis precludes the formulation of prognostic considerations. From their sites of origin, the tumors grow into the oral or nasal cavity or intracranially. Prenatal diagnosis is suggested by the demonstration of a solid tumor arising from the oral cavity; calcifications and cystic components may also be present. Differential diagnosis includes neck teratomas, encephaloceles, and other tumors of the facial structures. The outlook depends on the size of the lesion and the involvement of vital structures. The tumor occurs in females exclusively and it may be the consequence of excessive production of estrogens by the fetal ovaries under human chorionic gonadotropin stimulation. The ultrasound features are those of a large solid mass protruding from the fetal mouth. Ultrasound diagnosis is based on the demonstration of a solid, anteriorly located symmetric mass, which may result in hyperextension of the fetal head. Fetal blood sampling can aid in determining fetal thyroid status, especially in women suffering from Graves disease where a transplacental transfer of drugs or thyroid-stimulating antibodies may result in fetal goiter. The mortality rate in infants operated on within the first year of life is about 30%. Up to 80% of the infants with tuberous sclerosis have seizures and mental retardation, which are the most serious long term complications of the disease. Intrapericardial teratoma In the majority of cases, the tumor is located in the right side of the heart. However, occasionally, they are associated with arteriovenous shunting, congestive heart failure and hydrops, resulting in intrauterine or neonatal death. Neuroblastoma arises from undifferentiated neural tissue of the adrenal medulla or sympathetic ganglia in the abdomen, thorax, pelvis, or head and neck. Usually, the lesion is isolated, but occasional metastasis before birth may occur. Sonographically, the tumor appears as a cystic, solid, or complex mass in the region of the adrenal gland (directly above the level of the kidney and under the diaphragm). Diagnosis Sacrococcygeal teratomas usually appear solid or mixed solid and cystic (multiple cysts are irregular in shape and size). The tumor is invariably benign in the neonatal period but delayed surgery or incomplete excision can result in malignant transformation (about 10% before 2 months of age to about 80% by 4 months). While in many instances the underlying cause may be determined by maternal antibody and infection screening, fetal ultrasound scanning, including echocardiography and Doppler studies, and fetal blood sampling, quite often the abnormality remains unexplained even after expert post-mortem examination. Ultrasound Diagnosis Figure 1 longitudinal view, abdnormal accumulation of Figure 2 longitudinal view, abdnormal accumulation of serous fluid at the body cavities (pericardial, pleural, or serous fluid at the body cavities (pericardial, pleural, or ascitic effusions). Fetal therapy Immune hydrops can be successfully treated by blood transfusions to the fetus. Such treatment often results in reversal of hydrops and the survival rate is about 80%. Ultrasound findings the finding of a small abdominal circumference should stimulate the sonographer to consider four possible causes: wrong dates, normal small, abnormal small or starving small fetus. Additionally, a detailed examination should be carried out for the detection of any defects or markers of chromosomal abnormalities (mainly triploidy and trisomy 18), and for assessment of amniotic fluid and fetal activity. However, a repeat scan in two weeks may demonstrate a further deviation from normal in the various fetal measurements. Doppler ultrasound Doppler ultrasound provides a non-invasive method for the study of fetal haemodynamics. This is manifested by the absence or reversal of forward flow during atrial contraction in the ductus venosus and this is a sign of impending fetal death. These findings suggest that in fetal hypoxemia there is an increase in the blood supply to the brain and reduction in the perfusion of the kidneys, gastro intestinal tract and the lower extremities. Although knowledge of the factors governing circulatory readjustments and their mechanism of action is incomplete, it appears that partial pressures of oxygen and carbon dioxide play a role, presumably through their action on chemoreceptors. However, data derived from postnatal studies underestimate the association between chromosomal abnormalitites and growth retardation, since many pregnancies with chromosomally abnormal fetuses result in intrauterine death. The incidence of chromosomal defects is much higher in (a) fetuses with multiple malformations, than in those with no structural defects, (b) the group with normal or increased amniotic fluid volume, than in those with reduced or absent amniotic fluid, and (c) in the group with normal waveforms from both uterine and umbilical arteries, than in those with abnormal waveforms from either or both vessels. Etiology Oligohydramnios in the second trimester is usually the result of preterm premature rupture of the membranes, uteroplacental insufficiency and urinary tract malformations (bilateral renal agenesis, multicystic or polycystic kidneys, or urethral obstruction). Anecoic areas simulating pockets of amniotic fluid Color Doppler energy at the umbilical cord In the absence of the "accoustic window" normally provided by the amniotic fluid, and the "undesirable" postures often adopted by these fetuses, confident exclusion of fetal defects may be impossible. Prognosis Bilateral renal agenesis, multicystic or polycystic kidneys are lethal abnormalities, usually in the neonatal period due to pulmonary hypoplasia. Uteroplacental insufficiency resulting in oligohydramnios at 18-23 weeks is very severe and the most likely outcome is intrauterine death. Etiology There are essentially two major causes of polyhydramnios; reduced fetal swallowing or absorption of amniotic fluid and increased fetal urination. Reduced fetal swallowing may be due to craniospinal defects (such as anencephaly), facial tumours, gastrointestinal obstruction (such as esophageal atresia, duodenal atresia and small bowel obstruction), compressive pulmonary disorders (such as pleural effusions, diaphragmatic hernia or cystic adenomatoid malformation of the lungs), narrow thoracic cage (due to skeletal dysplasias), and fetal akinesia deformation sequence (due to neuromascular impairement of fetal swallowing). Although 80% of cases with mild polyhydramnios are considered to be idiopathic, in the majority of cases with moderate or severe polyhydramnios there are maternal or fetal disorders. In most cases polyhydramnios develops late in the second or in the third trimester of pregnancy. Testing for maternal diabetes, detailed sonographic examination for anomalies, and fetal karyotyping should constitute the cornerstones of the diagnostic protocol in the investigation of these cases. Treatment will obviously depend on the diagnosis, and will include better glycemic control of maternal diabetes mellitus, antiarrhythmic medication for fetal hydrops due to dysrrhythmias, thoracoamniotic shunting for fetal pulmonary cysts or pleural effusions. For the other cases, polyhydramnios may be treated by repeated amniocenteses every few days and drainage of large volumes of amniotic fluid. An alternative and effective method of treatment is maternal administration of indomethacin; however, this drug may cause fetal ductul constriction and close monitoring by serial fetal echocardiographic studies is necessary. In twin-to-twin transfusion syndrome, presenting with acute polyhydramnios at 18-23 weeks of gestation, endocopic laser occlusion of placental anastomoses or serial amniodrainage may be carried out.

In M1 asymptomatic patients, discuss deferred castration with a well-informed patient since it 2b B lowers the treatment side effects, provided the patient is closely monitored. Despite the high incidence and mortality rates in senior adults, they may be under-treated [587, 588]. Besides comorbidities, dependence in daily activities, malnutrition and cognitive impairment are associated with worse survival. Nutritional status can be estimated from body weight during the previous three months: Good nutritional status < 5% weight loss; Risk of malnutrition: 5-10% weight loss; Severe malnutrition: > 10% weight loss. In patients undergoing major elective surgery, there is an association between baseline cognitive impairment and long-term post operative complications and mortality [598]. Intervention is unlikely to reverse cognitive impairment, except in depression [599]. Patients with score G8 < 14 should undergo a full geriatric evaluation, assessing comorbidity, nutritional status, and cognitive and physical functions, to determine if the impairment is reversible [602]. Patients with irreversible impairment (disabled patients) should receive adapted treatment [599].

Patients with G8 score < 14 should undergo complete geriatric assessment to evaluate reversibility of any impairments [599]. Senior adults can be classified into one of four groups regarding health status based on G8 score > 14 (patient considered fit), or score < 14 (patient considered frail or disabled). The treatment policy is then: fit or healthy older men should receive standard treatment; frail patients may receive standard treatment after resolution of any geriatric problems; disabled patients. After resolution of reversible impairments, a similar urological approach should be carried out in fit or frail patients [1, 2]. Active treatment mostly benefits patients with intermediate or high-risk disease and longest expected survival. A recent study assessed the effect of age, health status and patient preferences on outcomes of surgery vs. Conversely, risk of long-term incontinence is influenced more by increasing age [604, 605]. In elderly and disabled patients, granulocyte colony-stimulating factor prophylaxis should be considered. Cabazitaxel, abiraterone acetate, enzalutamide, and sipuleucel-T increase survival in chemotherapy treated and chemotherapy-naive senior adults [611-617]. Offer standard treatment to frail patients (reversible impairment) after resolution of geriatric problems; 3.

A open, laparoscopic or robotic) as acceptable treatment options since none have clearly shown superiority in terms of functional or oncological results. Counsel patients about the possibility of needing further treatment in the A future. The lack of long-term efficacy compared to standard modality must be discussed with patients. Offer nerve-sparing surgery in patients with a low risk of extracapsular B disease (refer to nomograms). Offer castration combined with chemotherapy (docetaxel) to all patients A whose first presentation is M1 disease and who are fit enough for chemotherapy. Offer castration alone, with or without an anti-androgen, to patients unfit A for, or unwilling to consider, castration combined with chemotherapy. Do not prescribe abiraterone acetate or enzalutamide outside of a clinical A trial. In M1 symptomatic patients, offer immediate castration to palliate A symptoms and reduce the risk for potentially catastrophic sequelae of advanced disease (spinal cord compression, pathological fractures, urethral obstruction, extra-skeletal metastases). In M1 asymptomatic patients, offer immediate castration to defer A progression to a symptomatic stage and prevent serious disease progression-related complications. In M1 asymptomatic patients, discuss deferred castration with a well B informed patient since it lowers the treatment side effects, provided the patient is closely monitored. In M1 patients follow the schedules used in published clinical trials on C timing of intermittent treatment. In disabled or toosick senior adults, offer immediate androgen deprivation therapy only for 1b A symptom palliation. Offer minimally invasive energy-ablative therapies only to selected fit and frail senior adults 3 B with intermediate-risk disease. Advanced disease (locally advanced/metastatic disease) Evaluate bone mineral status and prevent osteoporosis-related fractures in senior adults. It should be emphasised that the treatment recommendations for these patients should be given after discussion in a multidisciplinary team. However, it must be stressed that most patients within the low-risk subgroup have an excellent outcome even without any salvage treatment. Patients within the high-risk subgroup need early and aggressive salvage treatment [628]. The dose delivered to the prostatic bed also tends to be uniform as it has not been demonstrated that a focal dose escalation at the site of recurrence improves the outcome. Given the morbidity of local salvage options, it is thus mandatory to obtain histological proof of the local recurrence before treating the patient [631] especially if a local salvage curative treatment is considered. They found that toxicity was similar in both arms, and that gynaecomastia was extremely common in the bicalutamide group. However, with dose escalation (72 Gy) or up to a median of 76 Gy, the rate of severe side effects especially for the genitourinary system clearly increases, even with newer planning and treatment techniques [682, 683]. The studied population is highly heterogeneous regarding their tumour biology and therefore clinical course. Non-steroidal anti-androgens have been claimed to be inferior compared to castration, but this difference was not seen in M0 patients [628]. In unselected relapsing patients, the median actuarial time to the development of metastasis will be eight years and the median time from metastasis to death will be a further five years [378]. Strong recommendations regarding the choice of any of these techniques cannot be made as the available evidence for these treatment options is of (very) low quality. The following is an overview of the most important findings regarding each of these techniques with a proposal for their indications. However, this must be weighed against the possible adverse events, which are increased compared to primary surgery because of the risk of fibrosis and poor wound healing due to radiation. The authors compared the oncological outcomes of the two salvage treatment options after mean follow-up periods of 7. In addition, 8-40% of patients reported persistent rectal pain, and an additional 4% of patients underwent surgical procedures for the management of treatment-associated complications. With the use of third-generation technology, complications such as urinary incontinence and obstruction/retention have significantly decreased during the last decade (see Table 6. However, the published series are relatively small and consequently this treatment should be offered in experienced centres only. The biochemical relapse-free survival after five years was 69% (median follow-up 36 months). Grade 2 late side effects were seen in 15% and one patient developed Grade 3 incontinence. However, the crude rate of > Grade 2 toxicity was 46% and > Grade 3 toxicity was 11%. These side effects were comparable with a series of 31 patients treated with salvage I-125 brachytherapy in the Netherlands. Important complication rates were mentioned and are at least comparable to other salvage treatment options. The surgical management of (recurrent) nodal metastases in the pelvis has been the topic of several retrospective analyses [730-732]. The majority of treated patients showed biochemical recurrence but clinical recurrence-free and cancer specific ten-year survival over 70% has been reported [731, 733]. It must however be remembered that the imaging modalities under-evaluate the real nodal involvement. The real efficacy of this salvage procedure remains unproven, as is its impact on survival [735]. Symptomatic progression alone must be questioned and subject to further investigation. These factors may be used when deciding which patients should be evaluated for metastatic disease. However, in the absence of prospective data, the modest potential benefits of a continuing castration outweigh the minimal risk of treatment. In addition, all subsequent treatments have been studied in men with ongoing androgen suppression and therefore it should be continued indefinitely in these patients. Patients were randomised to abiraterone acetate or placebo, both combined with prednisone [744]. Sub-set analysis of this trial showed the drug to be equally effective in an elderly population (> 75 years) [750]. Age by itself is not a contraindication to docetaxel [610] but attention must be paid to closer monitoring and comorbidities as discussed in Section 6. Two or more All secondary endpoints show a symptomatic bone benefit over best standard of care metastases. Patients received a maximum of ten cycles of cabazitaxel (25 mg/m2) or mitoxantrone (12 mg/m2) + prednisone (10 mg/ day), respectively. Overall survival was the primary end-point, which was significantly longer with cabazitaxel (median: 15. In any case, cabazitaxel should be administered by physicians with expertise in handling neutropenia and sepsis, preferably with prophylactic granulocyte colony-stimulating factor at least in the high-risk patient population [762]. Corticosteroids were not mandatory, but could be prescribed, and were received by 30% of the population. The benefit was observed irrespective of age, baseline pain intensity, and type of progression. It was also associated with prolonged time to first skeletal event, improvement in pain scores and improvement in QoL. The associated toxicity was mild and, apart from slightly more haematologic toxicity and diarrhoea with radium-223, this did not differ significantly from that in the placebo arm [758]. Radium-223 was effective and safe no matter if the patients were docetaxel pre-treated, or not [763]. Although not yet available they offer an exciting opportunity to tailor therapy based on the mutation profile contained within a tumour. In general however, and in unselected patients, subsequent treatments can be expected to have a smaller response [765, 766] with evidence of cross-resistance between enzalutamide and abiraterone [767]. As the number of effective treatments increases and without head to head trials or data assessing the effectiveness of different sequencing options, it is not clear how to choose the appropriate second-line treatment. In the absence of other data, the inclusion criteria from licensing trials have been used to prioritise treatment sequencing. A summary of the issues regarding sequencing are discussed in a paper published following the St. A multidisciplinary approach is often required with input from urologists, medical oncologists, radiation oncologists, nurses, psychologists and social workers [772]. Critical issues of palliation must be addressed when considering additional systemic treatment, including management of pain, constipation, anorexia, nausea, fatigue and depression, which often occur. Common complications due to bone metastases include vertebral collapse or deformity, pathological fractures and spinal cord compression. Cementation can be an effective treatment for painful spinal fracture, whatever its origin, clearly improving both pain and QoL [776]. However, it is still important to offer standard palliative surgery, which can be effective for managing osteoblastic metastases [777, 778]. It must be recognised early and patients should be educated to recognise the warning signs. This study was conducted when no active anticancer treatments but docetaxel were available. The 8 mg dose was poorly tolerated and reduced to 4 mg but did not show a significant benefit. However, these findings were not associated with any survival benefit and in a recent post-hoc re-evaluation of endpoints, denosumab showed identical results when comparing skeletal-related events and symptomatic skeletal events [782]. Patients should have a dental examination before starting therapy as the risk of jaw necrosis is increased by a history of trauma, dental surgery or dental infection [783]. Offer calcium and vitamin D supplementation when prescribing either denosumab or 1b A bisphosphonates.
