A Rare Obstetric Outcome in Uterus Didelphys with Obstructed Hemivagina and Ipsilateral Renal Agenesis

Background: The unique clinical syndrome of uterus didelphys, obstructed hemivagina, and ipsilateral renal anomaly is very rare and can be quite difficult to recognize because of the enormous heterogeneity in its clinical presentation. There are few long-term reports of the reproductive performance of women with this syndrome following treatment, or about the location of subsequent pregnancies. Case: A case in which two spontaneous pregnancies occurred alternatively in both hemiuteri: one despite a previous ipsilateral large hematometra and hematocolpos and the other, 8 years after, simultaneously with contralateral hematometra and hematocolpos(because of vaginal restenosis), is reported. Drainage of hematocolpos was performed at 14 weeks of pregnancy with immediate pain relief. Results: Pregnancy proceeded without complications. Eight month after delivery, a vaginoplasty was performed by excising the longitudinal vaginal septum, and marsupializing the vaginal cuff. Conclusions: This case highlights the importance of a correct and early diagnosis of developmental anomalies of the urogenital tract, as well as how a conservative approach in a Mullerian anomaly with unilateral obstruction led to two successful pregnancies occurring alternatively in the unaffected and in the previously blocked side. This is additional information supporting that every effort should be made to preserve the obstructed uterus.

Insuficiência Renal Crónica – Casuística de 16 Anos (1986-2001) da Unidade de Nefrologia do Hospital de Dona Estefânia

Entre Janeiro 1986 e Dezembro de 2001 foram seguidos na nossa Unidade 100 doentes com Insuficiência Renal Crónica com idade igual ou inferior a 15 anos (M:F = 54:46; idade ≥ 0 ≤15 anos). A idade de detecção da doença foi inferior aos dois anos em 35% dos casos. Cinquenta e nove doentes (59%) atingiram a fase de Insuficiência Renal Terminal no decurso destes 16 anos, tendo sido transplantados 41 (69,5%), encontrando-se no final do estudo 12 (20,3%) doentes em hemodiálise, três (5,1%) em diálise peritoneal e um em preparação para indução de diálise peritoneal. Registaram-se cinco óbitos, dois dos quais ocorreram após transplantação renal. Durante o período em estudo a hemodiálise foi a primeira forma de terapêutica de substituição da função renal em 33 casos (55,9%) dos doentes que atingiram a insuficiência renal terminal. Contudo a diálise peritoneal, instituida em 24 doentes (42,1%) foi a primeira escolha em 10 ( 100%) das crianças com menos de seis anos , submetidas a terapêutica de substituição da função renal. Dos 41 doentes transplantados registaramse dois óbitos e oito rejeições, com necessidade de instituição de hemodiálise em dois casos, de diálise peritoneal noutro e de duas retransplantações.

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.

Review of genitourinary tuberculosis with focus on end-stage renal disease

Tuberculosis (TB) is a current public health problem, remaining the most common worldwide cause of mortality from infectious disease. Recent studies indicate that genitourinary TB is the third most common form of extra-pulmonary disease. The diagnosis of renal TB can be hypothesized in a non-specific bacterial cystitis associated with a therapeutic failure or a urinalysis with a persistent leukocyturia in the absence of bacteriuria. We report on the case of a 33-year-old man who presented on admission end stage renal disease (ESRD) secondary to renal TB and a past history of pulmonary TB with important radiologic findings. The diagnosis was based on clinical findings despite all cultures being negative. Empiric treatment with tuberculostatic drugs was started and the patient became stable. He was discharged with no symptom, but without renal function recovery. He is on maintenance hemodialysis three times a week. TB is an important cause of kidney disease and can lead to irreversible renal function loss.

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.

Factores Preditivos de Cicatriz Renal após Pielonefrite em Crianças com Menos de Dois Anos de Idade

Objectivos. Identificar factores laboratoriais e imagiológicos associados ao desenvolvimento de cicatriz renal sequelar após pielonefrite em doentes com menos de dois anos de idade e avaliar o papel da ecografia no estudo não invasivo de pielonefrite. Local. Hospital pediátrico universitário de nível III. População. Crianças com idade inferior a dois anos hospitalizadas com o diagnóstico de primeira pielonefrite. Métodos. Avaliação prospectiva do risco de cicatriz renal, através de parâmetros laboratoriais e imagiológicos. Estudo de efectividade da ecografia renal e vesical para identificar pielonefrite aguda e refluxo vesico-ureteral (RVU). Admite-se como método padrão para detecção de pielonefrite aguda e cicatriz renal a cintigrafia renal com DMSA e para detecção de RVU, a cisto-uretografia permiccional (CUM). Resultados. Estudaram-se 134 crianças, com mediana de idades de 3 meses (p25-p75: 1-9 meses) sendo 60% do sexo masculino. Acintigrafia em ambulatório evidenciou a presença de cicatriz renal em 42% das crianças. Valores de proteína C reactiva superiores a 5 mg/dl estiveram associados a alterações da cintigrafia em ambulatório [RR 2,7 (IC95% 1,1-7), VP+ 64,3%, VP– 76,5%]. A presença de RVU grau ≥ II esteve associada a cicatriz renal na cintigrafia em ambulatório [RR 2,6 (IC95% 1,7-4,2), VP+ 100%, VP–51,7%]. Vinte por cento das crianças tinha RVU verificado pela CUM, tendo a ecografia excluído de forma significativa a sua presença, em relação à CUM [LR+ 9,9 (1,4-69,3), VP– 94,4%]. Conclusões. No grupo estudado, o valor de proteína C reactiva e a presença de RVU grau ≥ II foram os principais factores preditivos de cicatriz renal. O papel da ecografia parece ser relevante no estudo de pielonefrite, sobretudo para excluir RVU.

Anal squamous carcinoma: a new AIDS-defining cancer? Case report and literature review

Squamous anal cell carcinoma is a rare malignancy that represents the 1.5% to 2% of all the lower digestive tract cancers. However, an increased incidence of invasive anal carcinoma is observed in HIV-seropositive population since the widespread of highly active antiretroviral therapy. Human papillomavirus is strongly associated with the pathogenesis of anal cancer. Anal intercourse and a high number of sexual partners appear to be risk factors to develop anal cancer in both sexes. Anal pain, bleeding and a palpable lesion in the anal canal are the most common clinical features. Endo-anal ultrasound is the best diagnosis method to evaluate the tumor size, the tumor extension and the infiltration of the sphincter muscle complex. Chemoradiotherapy plus antiretroviral therapy are the recommended treatments for all stages of localized squamous cell carcinoma of the anal canal in HIV-seropositive patients because of its high rate of cure. Here we present an HIV patient who developed a carcinoma of the anal canal after a long time of HIV infection under highly active antiretroviral therapy with a good virological and immunological response.

THE SERO-CONVERSION AND EVALUATION OF RENAL ALTERATIONS IN DOGS INFECTED BY Leishmania (Infantum) chagasi

This study investigated the sero-conversion period in which dogs from endemic areas test positive for visceral leishmaniasis (VL) as well as the early post-infection period in which renal alterations are observed. Dogs that were initially negative for Canine Visceral Leishmaniasis (CVL) were clinically evaluated every three months by serological, parasitological and biochemical tests until sero-conversion was confirmed, and six months later a subsequent evaluation was performed. Samples of kidney tissues were processed and stained with Hematoxylin and Eosin (H&E), Periodic Acid Schiff (PAS) and Masson’s trichrome stain and lesions were classified based on the WHO criteria. Of the 40 dogs that initially tested negative for VL, 25 (62.5%) exhibited positive serological tests during the study period. Of these 25 dogs, 15 (60%) tested positive within three months, five (20%) tested positive within six months and five (20%) tested positive within nine months. The dogs exhibited antibody titers between 1:40 and 1:80 and 72% of the dogs exhibited clinical symptoms. The Leishmania antigen was present in the kidneys of recently infected dogs. We found higher levels of total protein and globulin as well as lower levels of albumin in the infected dogs when compared to the control dogs. Additionally, infected dogs presented levels of urea and creatinine that were higher than those of the uninfected dogs. Glomerulonephritis was detected in some of the dogs examined in this study. These data suggest that in Teresina, the sero-conversion for VL occurs quickly and showed that the infected dogs presented abnormal serum proteins, as well as structural and functional alterations in the kidneys during the early post-infection period.

RENAL HISTOPATHOLOGICAL FINDINGS IN DOGS WITH VISCERAL LEISHMANIASIS

Visceral leishmaniasis affects various organs including the kidneys; which can lead to renal failure and death. In order to verify this renal involvement, material was evaluated from 100 dogs naturally infected and with serological diagnosis of canine visceral leishmaniasis (CVL). Inflammatory changes were present in 25.3% of the tubules, in 67.0% of interstitium and in 52.0% of glomeruli. There was no significant difference (p > 0.05) between the presence of glomerulonephritis in symptomatic and oligosymptomatic dogs. The membranous and membranoproliferative glomerulonephritis were the most frequent, both with 18.0% frequency, followed by focal segmental glomerulosclerosis with 14.0%. Changes such as cylindruria, tubular and fibrosis hypertrophy, periglomerular inflammatory infiltrate, and multifocal and diffuse peritubular inflammatory infiltrate were observed. The findings are consistent with those of other authors indicating that renal involvement is common in CVL and the standards of membranous and membranoploriferative glomerulonephritis, as well as the tubulointerstitial involvement, are frequent.

Acidose Tubular Renal Distal e Surdez Neurossensorial com Mutação no Gene ATP6V1B1

A acidose tubular renal distal é uma doença rara, caracterizada pela incapacidade na acidificação da urina, condicionando acidose metabólica hiperclorémica, hipocaliémia, hipercalciúria e nefrocalcinose, o que poderá causar atraso de crescimento, alteração do metabolismo ósseo e insuficiência renal crónica. A acidose tubular renal distal associada a surdez neurossensorial é uma doença de herança autossómica recessiva, causada por mutações do gene que codifica a subunidade B1 da H+ -ATPase (ATP6V1B1). Os autores relatam os casos de duas irmãs que apresentaram má progressão ponderal, alterações iónicas, do equilíbrio ácido base e surdez neurossensorial. Foi detectada em ambas as crianças a mutação homozigótica no gene ATP6V1B1. Com estes dois casos pretende -se destacar a importância de um diagnóstico precoce nesta patologia rara.

Fototerapia no Prurido Renal e no Prurido Associado à Infecção pelo VIH

Introdução e Objectivos: A fototerapia (UVB isolados ou em combinação aos UVA) tem-se revelado eficaz no tratamento do prurido grave que complica, frequentemente, a doença renal crónica (DRC) ou a infecção pelo vírus da imunodeficiência humana (VIH). Pretendemos neste estudo avaliar a eficácia e segurança das radiações UVA e UVB de banda-larga, combinadas, no tratamento do prurido refractário associado à DRC e à infecção pelo VIH. Material e métodos: Para tal foi efectuado um estudo retrospectivo e descritivo de 83 doentes (55 com prurido renal e 28 com infecção pelo VIH), que efectuaram 3 sessões/semana de UVAB. Os UVB foram administrados na dose inicial de 20 a 30mJ/cm2 (70% da DEM), aumentados em 30mJ/cm2 por sessão, na ausência de eritema, até à regressão do prurido. As doses iniciais e subsequentes de UVA foram calculadas de acordo com o fototipo, não se ultrapassando a dose máxima de 6J/cm2. Resultados: Os doentes com prurido renal (33 homens e 22 mulheres) tinham em média 57,7 anos de idade, duração da DRC de 8,7 anos e do prurido de 27,8 meses; realizaram, em média 11,1 sessões de fototerapia com doses cumulativas de UVA de 22,9J/cm2 e de UVB de 1900mJ/cm2; verificou-se melhoria do prurido após 5 sessões e alivio completo no final do ciclo; todos os doentes continuavam assintomáticos após período médio de 11,2 meses. Os doentes com infecção VIH (18 homens e 10 mulheres) apresentavam, em média, idade de 40,8 anos, seropositividade conhecida há 2,5 anos, prurido generalizado com duração de 13,4 meses e contagem de CD4 de 177 células/μL; efectuaram, em média, 12,1 sessões de fototerapia, 24,3J/cm2 de UVA e 2000mJ/cm2 de UVB; em 21 doentes constatou-se diminuição do prurido após 5 sessões de UVAB e regressão completa no final do ciclo, permanecendo assintomáticos após período médio de 13,4 meses. Não ocorreram efeitos secundários, excepto pigmentação moderada e eritema ligeiro e transitório. Nos doentes com infecção pelo VIH não se detectou agravamento da imunossupressão. Conclusão: Estes resultados apoiam a eficácia e segurança da fototerapia combinada no controlo do prurido associado à DRC e à infecção pelo VIH, podendo o tratamento de um maior número de doentes confirmar as suas potenciais vantagens em relação aos UVA ou UVB utilizados isoladamente.
