Incontinência Urinária

O AA, após definir a U.I como um sintoma, um sinal e uma condição ilustra com estudos epidemiológicos que estamos perante um problema médico, social e económico maior. Por outro lado a fisioterapia da U.I. é explicada no contexto do equilíbrio entre as forças expulsivas e retencionistas na fase de enchimento. Deste modo explica a U.I por urgência devido a bexiga hiperactiva e a U.I. ao stress por hipermobilidade do colo da bexiga e ou lesão do esfíncter intrínseco. O diagnóstico e a severidade destes diferentes tipos de U.I. é apresentado tendo como base: a história clínica; o pad teste ; o registo diário demicções; o Q tip test. Os exames complementares como: O Rx simples do aparelho urinário; a urinocultura; os estudos urodinâmicos; a eco transvaginal avaliam os factores de continência alterados. O tratamento da U.I. é exposto tendo como base a fisiopatologia, e exemplificando de uma forma sistemática com casos clínicos.

Erythema induratum of Bazin and renal tuberculosis: report of an association

Erythema induratum of Bazin is a disease that usually affects women, in whom erythematous subcutaneous nodules and plaques appear on the posterior part of the lower extremities, some of which ulcerate. In many countries, tuberculosis is still the main etiologic factor. We report a case of a 40-year-old woman who presented a course of protracted and recurrent episodes over five years of cutaneous lesions on her legs. These tend to involute, but new crops appear at irregular intervals. It was painful, erythematous-violaceous nodules, some of which drained a reddish secretion. The histopathologic features of the lesions demonstrated inflammatory infiltration, with predominance of neutrophils in dermis and hypodermis, necrotizing vasculitis in the arterioles and septal fibrosis. There was no granuloma. The Ziehl-Neelsen stain did not revealed acid-fast bacilli, and the culture of biopsy specimen was negative. The tuberculin skin test was strongly positive (17 mm). The chest X-ray was normal. Few months later she presented adynamia and urinary complaints, such as polacyuria and dysuria. It has been done an urynalysis, which demonstrated acid pH urine, sterile pyuria and microscopic hematuria. It was then raised the diagnostic hypothesis of renal tuberculosis. The urine culture for M. tuberculosis was positive in two out of ten samples. The treatment was instituted with rifampin, isoniazid and pyrazinamide, with complete regression. This case illustrates a clear association between erythema induratum and renal tuberculosis, demonstrated by the remission of the cutaneous lesions after the treatment of the renal tuberculosis.

Dapsone hypersensitivity syndrome in an adolescent during treatment during of leprosy

A 12 y old girl was admitted 24 days after start a WHO multidrug therapy scheme for multibacillary leprosy (dapsone, clofazimine and rifampicin) with intense jaundice, generalized lymphadenopathy, hepatoesplenomegaly, oral erosions, conjunctivitis, morbiliform rash and edema of face, ankles and hands. The main laboratory data on admission included: hemoglobin, 8.4 g/dL; WBC, 15,710 cells/mm³; platelet count, 100,000 cells/mm³; INR = 1.49; increased serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transpeptidase, alkaline phosphatase, direct and indirect bilirubin. Following, the clinical conditions had deteriorated, developing exfoliative dermatitis, shock, generalized edema, acute renal and hepatic failure, pancytopenia, intestinal bleeding, pneumonia, urinary tract infection and bacteremia, needing adrenergic drugs, replacement of fluids and blood product components, and antibiotics. Ten days after admission she started to improve, and was discharged to home at day 39th, after start new supervised treatment for leprosy with clofazimine and rifampicin, without adverse effects. This presentation fulfils the criteria for the diagnosis of dapsone hypersensitivity syndrome (fever, generalized lymphadenopathy, exfoliative rash, anemia and liver involvement with mixed hepatocellular and cholestatic features). Physicians, mainly in geographical areas with high prevalence rates of leprosy, should be aware to this severe, and probably not so rare, hypersensitivity reaction to dapsone.

Acute generalized exanthematous pustulosis (AGEP). Case report

Acute Generalized Exanthematous Pustulosis (AGEP) is a drug-induced dermatosis characterized by an acute episode of sterile pustules over erythematous-edematous skin. It is accompanied by an episode of fever, which regresses a few days after discontinuation of the drug that caused the condition or as a result of corticosteroid treatment. The main triggering drugs are antibiotics, mainly beta-lactam ones. Other medications, such as antifungal agents, non steroid anti-inflammatory drugs, analgesics, antiarrhythmic, anticonvulsant and antidepressant drugs, may also be responsible. Histologically, it is characterized by the existence of vasculitis, associated with non-follicular subcorneal pustules. A case of a Caucasian female outpatient unit of Dermatology with AGEP, who presented with generalized pustulosis lesions after the use of cephalosporin for urinary infection is related. The diagnosis was confirmed by the clinical and pathological correlations, the resolution of the dermatosis after discontinuation of the drug and use of systemic corticosteroid treatment, and the recurrence of the disorder after the introduction of a similar drug. The importance of the recognition of this drug-induced dermatosis is given by its main differential clinical and histological diagnoses: generalized pustular psoriasis and subcorneal pustulosis.

Perfil do doente com infecção do trato urinário num serviço de ortopedia

RESUMO - As infecções do trato urinário são um problema constante nas unidades prestadoras de cuidados de saúde. Sabe-se que a incidência das mesmas é das mais elevadas em termos de infecções associadas aos cuidados de saúde, bem como acarretam fortes custos hospitalares devido ao aumento da demora média de internamento, uso de antibioterapia aumentado, entre outros. De modo a tentar compreender toda esta problemática, com a realização deste trabalho de projecto, pretende-se encontrar o perfil do doente com infecção do trato urinário num serviço de Ortopedia. Através deste mesmo perfil, tornar-se-á mais fácil uma vigilância epidemiológica e intervenções mais direccionadas ao problema em questão. Para tal, pretende-se construir um instrumento de colheita de dados que caracterize o doente de uma forma geral, antes, e durante o próprio internamento. Caso este mesmo instrumento fosse aplicado, pretender-se-ia cruzar as váriáveis concluindo eventualmente o perfil, justificando melhor o facto da existência de infecções urinárias e adequando medidas de prevenção. ------------ -ABSTRACT - The urinary infections are a constant problem in the health care facilities. It is known that the incidence of these infections is one of the biggest in terms of infections associated to health care, as well as they bring higher hospital costs, due to the middle delay of internment, the increased use of antibioterapy, as long as others. In the way of trying to understand all problems, with the realization of this work project, one intends to find the profile of the orthopedic patient with urinary infection, in the Orthopedic Service. Trough this same profile, it will be easier to do an epidemiological surveillance and more directed interventions to the problem in matter. To achieve this goal, it is claimed to build an instrument of data collection that characterizes the patient in a general way, before and during the internment. If this instrument would be applied, it would be intended to cross the variables concluding eventually the profile, justifying better the fact of the existence of urinary infection

Virulence factors of uropathogenic Escherichia coli from a University Hospital in Ribeirão Preto, São Paulo, Brazil

The aim of the study was to determine the occurrence of virulence genes expressing fimbriae, production of hemolysin, colicin and aerobactin among a hundred Escherichia coli isolates obtained from in-and outpatients of a tertiary-care teaching hospital, between July and August 2000, showing clinical and laboratory signs of urinary tract infection (UTI). The presence of genes (pap, afa, sfa) for fimbriae expression was assayed using specific primers in a polymerase chain reaction. Among the isolates studied, the prevalence of the virulence factors was 96.0%, 76.0%, 24.0%, for hemolysin, aerobactin and colicin, respectively; the prevalence of genes coding for fimbrial adhesive systems was 32.0%, 19.0% and 11.0% for pap, sfa and afa respectively. The strains isolated from the outpatients displayed a greater number of virulence factors compared to those from hospitalized subjects, emphasizing the difference between these two kinds of patients.

Clinical and epidemiological aspects of HTLV-II infection in São Paulo, Brazil: presence of Tropical Spastic Paraparesis/HTLV-Associated Myelopathy (TSP/HAM) simile diagnosis in HIV-1-co-infected subjects

In this study, the epidemiological and clinical features observed in solely HTLV-II-infected individuals were compared to those in patients co-infected with HIV-1. A total of 380 subjects attended at the HTLV Out-Patient Clinic in the Institute of Infectious Diseases "Emilio Ribas" (IIER), São Paulo, Brazil, were evaluated every 3-6 months for the last seven years by infectious disease specialists and neurologists. Using a testing algorithm that employs the enzyme immuno assay, Western Blot and polymerase chain reaction, it was found that 201 (53%) were HTLV-I positive and 50 (13%) were infected with HTLV-II. Thirty-seven (74%) of the HTLV-II reactors were co-infected with HIV-1. Of the 13 (26%) solely HTLV-II-infected subjects, urinary tract infection was diagnosed in three (23%), one case of skin vasculitis (8%) and two cases of lumbar pain and erectile dysfunction (15%), but none myelopathy case was observed. Among 37 co-infected with HIV-1, four cases (10%) presented with tropical spastic paraparesis/HTLV-associated myelopathy (TSP/HAM) simile. Two patients showed paraparesis as the initial symptom, two cases first presented with vesical and erectile disturbances, peripheral neuropathies were observed in other five patients (13%), and seven (19%) patients showed some neurological signal or symptoms, most of them with lumbar pain (five cases). The results obtained suggest that neurological manifestations may be more frequent in HTLV-II/HIV-1-infected subjects than those infected with HTLV-II only.

Role of oxidative stress-induced systemic and cavernosal molecular alterations in the progression of diabetic erectile dysfunction

Background Erectile dysfunction (ED) is a prevalent complication of diabetes, and oxidative stress is an important feature of diabetic ED. Oxidative stress-induced damage plays a pivotal role in the development of tissue alterations. However, the deleterious effects of oxidative stress in the corpus cavernosum with the progression of diabetes remain unclear. The aim of this study was to evaluate systemic and penile oxidative stress status in the early and late stages of diabetes. Methods Male Wistar streptozotocin-diabetic rats (and age-matched controls) were examined 2 (early) and 8 weeks (late) after the induction of diabetes. Systemic oxidative stress was evaluated by urinary H2O2 and the ratio of circulating reduced/oxidized glutathione (GSH/GSSG). Penile oxidative status was assessed by H2O2 production and 3-nitrotyrosine (3-NT) formation. Cavernosal endothelial nitric oxide synthase (eNOS) was analyzed by quantitative immunohistochemistry. Dual immunofluorescence was also performed for 3-NT and α-smooth muscle actin (α-SMA) and eNOS–α-SMA. Results There was a significant increase in urinary H2O2 levels in both diabetic groups. The plasma GSH/GSSG ratio was significantly augmented in late diabetes. In cavernosal tissue, H2O2 production was significantly increased in late diabetes. Reactivity for 3-NT was located predominantly in cavernosal smooth muscle (SM) and was significantly reduced in late diabetes. Quantitative immunohistochemistry revealed a significant decrease in eNOS levels in cavernosal SM and endothelium in late diabetes. Conclusions The findings indicate that the noxious effects of oxidative stress are more prominent in late diabetes. Increased penile protein oxidative modifications and decreased eNOS expression may be responsible for structural and/or functional deregulation, contributing to the progression of diabetes-associated ED.

Fitas Suburetrais Transobturadoras na Incontinência Urinária de Esforço Feminina. Resultados a Médio Prazo

Introdução: O tratamento cirúrgico mini-invasivo da incontinência urinária de esforço feminina com próteses suburetrais aplicadas por via transobturadora é consensualmente aceite na actualidade. O objectivo deste estudo é avaliar eficácia e segurança das próteses suburetrais transobturadoras a médio prazo, comparando a abordagem outside-in com a inside-out. Material e Métodos: Estudo retrospectivo de 298 doentes com diagnóstico de incontinência urinária de esforço submetidas entre 2003 e 2006 a cirurgia por via transobturadora. Destas doentes 113 mulheres realizaram a abordagem outside-in e 185 a abordagem insideout. Resultados: A média etária das doentes foi de 57.2 ± 10.3 anos, em que 69.1% se encontravam na menopausa. A paridade média foi de 2.2 ± 1.1. A técnica outside-in foi utilizada com maior frequência em associação com outra(s) cirurgia(s) do pavimento pélvico (83.2% versus 37.8% na técnica inside-out). O tempo médio de follow-up foi de 14.35 ± 13.75 meses nas doentes com prótese aplicada outside-in e de 11.79 ± 10.39 meses no grupo inside-out. Os resultados globais de eficácia obtidos foram idênticos nos dois grupos com taxas de cura e cura ou melhoria, respectivamente, de 76.9% e 92.9% no grupo outside-in e de 82.7% e 93.5% no grupo inside-out (diferença não significativa). A duração média da cirurgia para incontinência urinária de esforço isolada foi significativamente menor no grupo inside-out (14.77 ± 5.37 minutos versus 21.21 ± 7.48 minutos, p < 0.05). No pós-operatório a frequência de incontinência por imperiosidade de novo e de erosões da prótese foi idêntica em ambos as técnicas, contudo as erosões foram mais frequentes nas próteses microporosas do que nas macroporosas (p < 0.05). Discussão e conclusões: As próteses transobturadoras usadas no tratamento da I.U.E. são eficazes e seguras. As taxas de cura e melhoria são elevadas, com diferenças não significativas em função da técnica utilizada. A técnica inside-out associa-se a um significativo menor tempo cirúrgico.

Infecções Urinárias e Gravidez - Diagnóstico, Terapêutica e Prevenção

Objectives: Literature review of classification, epidemiology, pathophysiology, microbiology, clinical presentation, diagnosis, complications, treatment and prevention of urinary tract infections (UTI) in pregnancy. Data Sources and Review Methods: Bibliographic research in Medline, through PubMed and Medscape, of systematic reviews, observational studies, clinical guidelines, meta-analyses and randomized controlled trials published between January 1992 and December 2010. Results: Asymptomatic bacteriuria occurs in 2 to 10% of pregnant women, 30% of which will develop acute pyelonephritis if left untreated. Treatment of asymptomatic bacteriuria has been shown to reduce the risk of pyelonephritis in pregnancy. Therefore, screening and treatment of this form of UTI has become a standard of obstetrical care, although the ideal duration of the treatment is still controverse. Acute pyelonephritis is one of the most common medical complications of pregnancy and may be associated with maternal, obstetric and perinatal complications. There is no clear consensus in the literature regarding antibiotic choice or duration of therapy for symptomatic UTI. Increasing antibiotic resistance complicates the choice of empirical regimens and local resistance rates need to be taken into account when deciding the therapy. Considering the high rate of recurrence of UTI during pregnancy, prophylactic measures need to be taken in pregnant women who have already experienced UTI during their current pregnancy. Conclusions: Although UTI is a generally benign condition in non-pregnant women, it may be a potentially serious complication during pregnancy. Early diagnosis and treatment of UTI during pregnancy are mandatory and can prevent severe maternal and perinatal complications.

Case Report: Purple Urine Bag Syndrome

Purple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with tryptophan as described in the article.

Genotypic characterization of virulence factors in Escherichia coli strains from patients with cystitis

Adhesins (P-fimbriae, S-fimbriae, type 1 fimbriae and afimbrial adhesin), toxins (α-hemolysin and cytotoxic necrotizing factor type 1), iron acquisition systems (aerobactin) and host defense avoidance mechanisms (capsule or lipopolysaccharide) have been shown to be prevalent in Escherichia coli strains associated with urinary tract infections. In this work, 162 Uropathogenic Escherichia coli (UPEC) strains from patients with cystitis were genotypically characterized by polymerase chain reaction (PCR) assay. We developed three multiplex PCR assays for virulence-related genes papC, papE/F, papG alleles, fimH, sfa/foc, afaE, hly, cnf-1, usp, cdtB, iucD, and kpsMTII, all of them previously identified in UPEC strains. The PCR assay results identified 158 fimH (97.5%), 86 kpsMTII (53.1%), 53 papC/papEF/papG (32.7%), 45 sfa (27.8%), 42 iucD (25.9%), 41 hly (25.3%), 36 usp (22.2%), 30 cnf-1(18.5%) and 10 afa (6.2%) strains. No strain was positive for cdtB. In this work, we also demonstrated that adhesins may be multiple within a single strain and that several virulence genes can occur combined in association.

Schistosomiasis haematobia: histopathological course determined by cystoscopy in a patient in whom praziquantel treatment failed

Schistosomiasis haematobia or urinary schistosomiasis is one of the main public health problems in Africa and the Middle East. A single dose of 40 mg praziquantel per kg body weight continues to be the treatment of choice for this infection. The aims of this follow-up were to study the post-treatment course of a patient infected with S. haematobium and not submitted to re-exposure, and to identify complications of the disease and/or therapeutic failure after praziquantel treatment by histopathological analysis. Treatments were repeated under medical supervision to ensure the correct use of the drug. In view of the suspicion of lesions in cystoscopy, the patient was submitted to bladder biopsy. The histopathological characteristics observed in biopsies obtained, after each treatment, indicated viability of parasite eggs and activity of granulomas.

Prostatic Artery Embolization in the Treatment of Benign Prostatic Hyperplasia: Short and Medium Follow-Up

To evaluate the short and mid-term results of prostatic artery embolization in patients with benign prostatic embolization. Retrospective study between March 2009 and June 2011 with 103 patients (mean age 66.8 years, 50-85) that met our inclusion criteria with symptomatic benign prostatic hyperplasia. The clinical outcome was evaluated by the International Prostate Symptom Score (IPSS), quality of life (QoL), International Index of Erectile Function, prostate volume (PV), prostate-specific antigen (PSA), peak urinary flow (Q(max)), and post-void residual volume (PVR) measurements at 3 and 6 months, 1 year, 18 months, and 2 years after PAE and comparison with baseline values was made. Technical and clinical successes, as well as poor clinical outcome definitions, were previously defined. In this review, we evaluate the short and mid-term clinical outcomes and morbidity of patients treated only with non-spherical polyvinyl alcohol. Six months after the procedure, the PV decreased about 23%, IPSS changed to a mean value of 11.95 (almost 50% reduction), the QoL improved slightly more than 2 points, the Q(max) changed to a mean value of 12.63mL/s, the PVR underwent a change of almost half of the baseline value, and the PSA decreased about 2.3ng/mL. In the mid-term follow-up and comparing to the baseline values, we still assisted to a reduction in PV, IPSS, QoL, PVR, and PSA, and an increase in Q(max). Prostatic Artery Embolization is a safe procedure with low morbidity that shows good short- and mid-term clinical outcome in our institution.

Clinical and Pathological Findings in Women with Fabry Disease

Introduction. Fabry disease is a rare metabolic disorder caused by the genetic deficiency of the lysosomal hydrolase alpha-galactosidase A, located on chromosome X. Females with the defective gene are more than carriers and can develop a wide range of symptoms. Nevertheless, disease symptoms generally occur later and are less severe in women than in men. The enzyme deficiency manifests as a glycosphingolipidosis with progressive accumulation of glycosphingolipids and deposit of inclusion bodies in lysosomes giving a myelinlike appearance. Patients and Methods. Records of renal biopsies performed on adults from 1st January 2008 to 31st August 2011, were retrospectively examined at the Renal Pathology Laboratory. We retrieved biopsies diagnosed with Fabry disease and reviewed clinical and laboratory data and pathology findings. Results. Four female patients with a mean age of 49.3±4.5 (44-55) years were identified. The mean proteinuria was 0.75±0.3 g/24h (0.4-1.2) and estimated glomerular filtration rate (CKD EPI equation) was 71±15.7 ml/min/1.73m2 (48-83). Three patients experienced extra-renal organ involvement (cerebrovascular, cardiac, dermatologic, ophthalmologic and thyroid) with distinct severity degrees. Leukocyte α-GAL A activity was below normal range in the four cases but plasma and urinary enzymatic activity was normal. Light microscopy showed predominant vacuolisation of the podocyte cytoplasm and darkly staining granular inclusions on paraffin and plastic-embedded semi-thin sections. Electron microscopy showed in three patients the characteristic myelin-like inclusions in the podocyte cytoplasm and also focal podocyte foot process effacement. In one case the inclusions were also present in parietal glomerular cells, endothelial cells of peritubular capillary and arterioles. Conclusion. Clinical signs and symptoms are varied and can be severe among heterozygous females with Fabry disease. Intracellular accumulation of glycosphingolipids is a characteristic histologic finding of Fabry nephropathy. Since this disease is a potentially treatable condition, its early identification is imperative. We should consider it in the differential diagnosis of any patient presenting with proteinuria and/or chronic kidney disease, especially if there is a family history of kidney disease.
