Displasia Quística Testicular: A Propósito de um Caso Clínico

A displasia quística testicular é uma patologia benigna e rara, frequentemente associada a outras anomalias génito-urinárias, que se apresenta na infância sobretudo com aumento do volume escrotal, fazendo diagnóstico diferencial com situações neoplásicas e inflamatórias do testículo. Embora classicamente considerada indicação para orquidectomia, não parece haver qualquer potencial maligno, pelo que se pode argumentar uma abordagem conservadora. No entanto é importante confirmar o diagnóstico e manter vigilância para precaver a atrofia do parênquima testicular. Os autores apresentam o caso clínico de um doente com antecedentes de agenésia renal esquerda e megauretero obstructivo direito, submetido a orquidectomia no contexto de displasia quística testicular esquerda com atrofia importante do parênquima.

Pancreatic Involvement by Plasma Cell Neoplasms

INTRODUCTION: Pancreatic involvement by plasma cell neoplasms is an extremely rare event, with only 50 cases described in the literature. They can present as a primary solitary extramedullary plasmacytoma or plasmacytoma secondary to a plasma cell myeloma. Clinical manifestations are due to the presence of a pancreatic mass usually in the pancreas head, which causes extra-biliary obstruction and abdominal pain. METHODS: Abdominal imaging including CT scan or endoscopic ultrasound with fine-needle aspiration tissue sampling is essential for the initial diagnostic procedure. However, immunohistochemical analysis of the biopsy specimen or flow cytometry of the aspirated material is crucial to prove the monoclonality and the final diagnosis of a plasma cell neoplasm. DISCUSSION: Management of these situations include radiotherapy, chemotherapy, surgery or combined therapy. Novel medications including the immunomodulatory drugs or the proteasome inhibitors followed by consolidation with intensive chemotherapy and haematopoietic stem cell transplantation are nowadays used as upfront treatment in the cases associated to a plasma cell myeloma. CONCLUSION: Despite the rarity, plasma cell neoplasms should be considered in the differential diagnosis of obstructive jaundice and pancreatic neoplasms since they are potentially treatable situations.

A Utilização de Endopróteses na Síndrome da Veia Cava Superior por Neoplasia do Pulmão

Apresentam-se seis casos de síndrome da veia cava superior causado por neoplasia do pulmão e que foram tratados por endopróteses colocadas por via percutânea. Descreve-se a técnica e avaliam-se os resultados. Num caso ocorreu trombose aguda da endoprótese que foi tratada por uroquinase. Não se registaram outras complicações. Um doente faleceu 1 mês depois por progressão da doença. Os restantes mantinham-se sem queixas de síndrome da veia cava superior durante mais do que 6 meses. Conclui-se que a colocação de endopróteses é uma técnica pouco invasiva, eficaz e com melhoria imediata no síndrome da veia cava superior.

Use of Distress and Depression Thermometers to Measure Psychosocial Morbidity Among Southern European Cancer Patients

GOALS OF WORK: Recent literature has indicated the need for rapid evaluation of psychosocial issues secondary to cancer. Because of the problems of routine use of psychometric instruments, short instruments such as visual analogue scales or one-item 0-10 scales have been developed as valid assessment alternatives. PATIENTS AND METHODS: A study was conducted to examine the role of two 0-10 scales in measuring emotional stress (distress thermometer, DT) and depressed mood (mood thermometer, MT), respectively, in a multicenter study carried out in southern European countries (Italy, Portugal, Spain, and Switzerland). A convenience sample of 312 cancer outpatients completed the DT and MT and the Hospital Anxiety Depression Scale (HADS). MAIN RESULTS: DT was more significantly associated HADS anxiety than HADS depression while MT was related both to HADS anxiety and depression. The correlation of MT with HADS was higher than DT. A cutoff point >4 on the DT maximized sensitivity (65%) and specificity (79%) for general psychosocial morbidity while a cutoff >5 identified more severe "caseness" (sensitivity=70%; specificity=73%). On the MT, sensitivity and specificity for general psychosocial morbidity were 85% and 72% by using the cutoff score >3. A score >4 on the MT was associated with a sensitivity of 78% and a specificity of 77% in detecting more severe caseness. CONCLUSIONS: Two simple instruments, the DT and the MT, were found to have acceptable levels of sensitivity and specificity in detecting psychosocial morbidity. Compared to the HADS, however, the mood MT performed better than the DT.

Do Spirituality and Faith Make a Difference? Report from the Southern European Psycho-Oncology Study Group

OBJECTIVE: In the last decade, some attention has been given to spirituality and faith and their role in cancer patients' coping. Few data are available about spirituality among cancer patients in Southern European countries, which have a big tradition of spirituality, namely, the Catholic religion. As part of a more general investigation (Southern European Psycho-Oncology Study--SEPOS), the aim of this study was to examine the effect of spirituality in molding psychosocial implications in Southern European cancer patients. METHOD: A convenience sample of 323 outpatients with a diagnosis of cancer between 6 to 18 months, a good performance status (Karnofsky Performance Status > 80), and no cognitive deficits or central nervous system (CNS) involvement by disease were approached in university and affiliated cancer centers in Italy, Spain, Portugal, and Switzerland (Italian speaking area). Each patient was evaluated for spirituality (Visual Analog Scale 0-10), psychological morbidity (Hospital Anxiety and Depression Scale--HADS), coping strategies (Mini-Mental Adjustment to Cancer--Mini-MAC) and concerns about illness (Cancer Worries Inventory--CWI). RESULTS. The majority of patients (79.3%) referred to being supported by their spirituality/faith throughout their illness. Significant differences were found between the spirituality and non-spirituality groups (p ≤ 0.01) in terms of education, coping styles, and psychological morbidity. Spirituality was significantly correlated with fighting spirit (r = -0.27), fatalism (r = 0.50), and avoidance (r = 0.23) coping styles and negatively correlated with education (r = -0.25), depression (r = -0.22) and HAD total (r = -0.17). SIGNIFICANCE OF RESULTS: Spirituality is frequent among Southern European cancer patients with lower education and seems to play some protective role towards psychological morbidity, specifically depression. Further studies should examine this trend in Southern European cancer patients.

Tumores do Corpo Carotídeo. Experiência de um Serviço no Diagnóstico e Tratamento nos Últimos 10 Anos

INTRODUCTION: Carotid body tumours (CBT) are neoplasms that develop from paragangionic cells of this structure. They are rare, with an estimated incidence of 1:30000 and can be associated with other neuro-endocrine neoplasia. The authors report their experience in the management of the disease, in the last 10 years. MATERIAL AND METHODS: Eight patients (with eight tumours) were treated, all submitted to tumour resection. 75% were female and the mean age was 56 years. We report a 12,5% incidence of neurological sequelae from surgery, and no mortality. In the follow-up (which varied between 1 and 10 years), no local or contralateral recurrence or metastasis were registered. Also, we did not found family cases of this disease. CONCLUSIONS: The authors noticed an unusually high proportion of female patients. The tumour resection was curative in all patients, with a rate of neurological complications inferior to that reported in other published series. These neurological sequelae were reported in patients with large tumours, thus reinforcing the outmost importance of an early diagnosis. Pre-operative selective embolization of these tumours can be helpful in the resection of large tumours, allowing a potential reduction in neurological complications.

Seminoma Espermatocítico: Caso Clínico e Revisão

Introdução: O seminoma espermatocítico é um diagnóstico incomum de tumores do testículo, frequentemente exuberantes na sua dimensão, mas com bom prognóstico. Apesar da designação errónea, trata-se de tumores de células germinativas do tipo não-seminoma. Caso Clínico: Descreve-se o caso clínico de um homem de 49 anos de idade, com exuberante aumento de volume escrotal de agravamento recente, à custa de massa indolor do testículo direito. Foi feita ecografia escrotal que mostrou hidrocelo e imagem sugestiva de massa atípica do epidídimo direito. TC torácica, abdominal e pélvica não mostrou adenomegalias retroperitoneais ou outra alteração; os valores de LDH, αFP e βHCG eram normais. Foi feita orquidectomia por via escrotal à direita, com excisão de uma ampla área do escroto. Identificou-se na peça operatória, com 1375g, seminoma espermatocítico com invasão vascular da túnica albugínea (pT2). O doente iniciou quimioterapia com BEP (dois ciclos). Discussão: O seminoma espermatocítico é raro, com cerca de 2% de incidência, o diagnóstico faz-se habitualmente na 6ª década de vida, e tem localização exclusivamente testicular. A orquidectomia é frequentemente curativa. Apesar de estarem descritos tumores de maior volume do que o seminoma clássico, destaca-se neste caso a exuberância clínica incomum pela dimensão do testículo, bem como do hidrocelo que o acompanhava.

Síndrome de Klinefelter no Adulto: um Caso e Revisão Breve

Introdução: O diagnóstico de Síndrome de Klinefelter é habitualmente tardio (na idade adulta), devido à paucidade de sintomas e amplo espectro clínico e fenotípico, e é frequentemente feito na sequência do estudo de causas de infertilidade. Volume testicular reduzido e azoospermia são as características clínicas mais prevalentes. Caso Clínico: Este artigo descreve o caso clínico de um homem de 40 anos de idade, saudável, que recorreu à consulta de Urologia por testículo esquerdo retráctil e doloroso. Na sequência da avaliação destas queixas foi feita uma ecografia escrotal que mostrou heterogeneidade e atrofia testicular, bem como imagem nodular do testículo direito. Analiticamente, tinha marcadores tumorais normais e o estudo hormonal mostrou diminuição do valor de testosterona e aumento de FSH e LH. Para além disso, o espermograma revelou azoospermia. Foi feita orquidopexia à esquerda e biopsia testicular que mostrou hipertrofia das células de Leydig, sem atipias. O cariótipo feito posteriormente mostrou presença de um cromossoma X supra-numerário em todas as células, compatível com diagnóstico de Síndrome de Klinefelter. Discussão e Conclusão: O estudo da infertilidade é frequentemente aquilo que conduz ao diagnóstico desta síndrome, caracterizada por diminuição das dimensões dos testículos, azoospermia, diminuição do valor sérico de testosterona e alteração do desenvolvimento sexual secundário. É importante o acompanhamento dos doentes para despiste de outras patologias que lhe estão associadas (neoplasia do testículo e da mama, osteoporose), tratamento com suplementação androgénica, quando indicado, e tratamento da infertilidade. Apesar da obtenção de resultados animadores em doentes com espermatozóides identificados na biópsia testicular, por extracção(TESE, testicular sperm extraction) e injecção intracitoplasmática de espermatozóides (ICSI, intracytoplasmic sperm injection), estes restringem-se apenas a alguns centros com experiência.

Watermelon Stomach, Hemorrhagic Pericarditis, Small Cell Carcinoma of the Lung and Synchronous Squamous Cell Carcinoma of the Tongue Base

Based on a case of gastric antral vascular ectasia (watermelon stomach) that was associated with hemorrhagic pericarditis, small cell lung carcinoma with mediastinal lymph node metastases and a synchronous squamous cell carcinoma of the base of the tongue, the authors made a review of the clinical, endoscopic and histopathological aspects of this type of gastropathy, and its association with other diseases, and of the results of its endoscopic therapy. The causes of hemorrhagic pericarditis are considered, emphasizing the necessity to know if the effusion has a malignant etiology. To the best of our knowledge the association of watermelon stomach to small cell lung carcinoma and squamous cell carcinoma of the base of the tongue has not yet been described. Extensive metastases to mediastal lymph nodes are common to small cell lung carcinoma.

Leprosy and Kaposi Sarcoma Presenting as an Immune Reconstitution Inflammatory Syndrome in a Patient with AIDS

The simultaneous presence of infectious organisms within cutaneous lesions of Kaposi sarcoma in persons with AIDS has been demonstrated. We describe a patient with concurrent leprosy and Kaposi sarcoma presenting as an immune reconstitution inflammatory syndrome in the setting of AIDS.

O Varicocelo em Idade Pediátrica

Nos últimos anos o tratamento do varicocelo em idade pediátrica ganhou particular importância devido a evidencia clínica e experimental de atrofia testicular e alterações histo1ógicas em cerca de 50% dos testículos homolaterais e com frequência no contralateral. Estas alterações são progressivas e sobreponíveis às encontradas no adulto inférti1 com varicocelo. Os autores procederam ao estudo retrospectivo de 41 crianças e adolescentes com varicocelo que recorreram a Consulta de Cirurgia Pediátrica do Hospital de Dona Estefânia entre 1 de Janeiro de 1990 e 31 de Dezembro de 1994.O motivo de consulta foi, em quase todos os casos, a existência de uma massa escrotal. As idades estavam compreendidas entre os cinco e os 15 anos, com média etaria de 11,9 anos. O varicocelo localizava-se à esquerda em 39 doentes,à direita em um doente e apenas um caso era bilateral. Todos os casos eram varicocelos primários, sendo mais frequentemente o de grau II (57%). Foram feitas 40 varicocelectomias, 31 das quais (77%) pela técnica de Ivanisevíc. Quatro varicocelos recidivaram ( 10%). Os autores comentam os resultados e tecem algumas considerações sobre a atitude cirúrgica perante um varicocelo diagnosticado em idade pediátrica.

Hopelessness and Related Variables among Cancer Patients in the Southern European Psycho-Oncology Study (SEPOS).

BACKGROUND: Although hopelessness has been studied in cancer, no data are available in non-English-speaking countries. OBJECTIVE: The authors sought to amass data from Southern European countries (Italy, Portugal, Spain, and Switzerland) in order to fill this void. METHOD: A group of 312 cancer patients completed the Mini-MAC Hopelessness subscale, the Hospital Anxiety and Depression Scale (HADS), the Cancer Worry Inventory (CWI), and a six-item Visual Analog scale (VAS) to measure intensity of physical symptoms, general well-being, difficulty in coping with cancer, intensity of social support from close relationships, leisure activity, and support from religious beliefs. RESULTS: Regression analysis indicated that HADS-Depression, VAS Maladaptive Coping and Well-Being, and the CWI explained 42% of the variance. CONCLUSION: Hopelessness in cancer patients seems not exclusively to correspond to depression, but is related to various other psychosocial factors, such as maladaptive coping, as well.

A Communication Intervention for Training Southern European Oncologists to Recognize Psychosocial Morbidity in Cancer. I - Development of the Model and Preliminary Results on Physicians' Satisfaction

BACKGROUND: The detection of psychosocial distress is a significant communication problem in Southern Europe and other countries. Work in this area is hampered by a lack of data. Because not much is known about training aimed at improving the recognition of psychosocial disorders in cancer patients, we developed a basic course model for medical oncology professionals. METHODS: A specific educational and experiential model (12 hours divided into 2 modules) involving formal teaching (ie, journal articles, large-group presentations), practice in small groups (ie, small-group exercises and role playing), and discussion in large groups was developed with the aim of improving the ability of oncologists to detect emotional disturbances in cancer patients (ie, depression, anxiety, and adjustment disorders). RESULTS: A total of 30 oncologists from 3 Southern European countries (Italy, Portugal, and Spain) participated in the workshop. The training course was well accepted by most participants who expressed general satisfaction and a positive subjective perception of the utility of the course for clinical practice. Of the total participants, 28 physicians (93.3%) thought that had they been exposed to this material sooner, they would have incorporated the techniques received in the workshop into their practices; 2 participants stated they would likely have done so. Half of the doctors (n = 15) believed that their clinical communication techniques were improved by participating in the workshop, and the remaining half thought that their abilities to communicate with cancer patients had improved. CONCLUSIONS: This model is a feasible approach for oncologists and is easily applicable to various oncology settings. Further studies will demonstrate the effectiveness of this method for improving oncologists skills in recognizing emotional disorders in their patients with cancer.

Scalp Porocarcinoma: a Rare Diagnosis

Adnexal skin tumours are rare conditions, and often clinically indistinguishable from other cutaneous neoplasms. Porocarcinoma, a sweat gland malignant tumour, is more commonly found on extremities. Few reports in other anatomic locations can be found in the literature, and those arising on the scalp are even scarcer. The authors report the case of an 84-year-old diabetic man, with a tumour on the left parietal region for 1 year, which histopathological features were consistent with porocarcinoma. The importance of histopathologic diagnosis is hereby emphasized by the more aggressive behaviour of this tumour, therefore requiring clinical actuation accordingly.
