Abstract Introduction The tongue plays an important role in the development of craniofacial structures. At rest, the light and constant pressure of the tongue against the hard palate, counterbalanced by the pressure provided by proper lip sealing, serves as a guide for maxillary growth. Ankyloglossia makes tongue coupling against the hard palate difficult, impacting maxillary development, which may lead to breathing disorders. Objective To verify the effect of lingual frenotomy on the resting position of the tongue and lips in infants with ankyloglossia. Methods The sample consisted of 334 infants aged between 1 and 60 days old diagnosed with ankyloglossia. The groups were divided in: a) experimental group (EG), which consisted of infants whose mothers agreed with lingual frenotomy; b) control group (CG), which consisted of infants whose mothers either refused lingual frenotomy or were waiting for surgery. Both the position of the lips and of the tongue at rest were assessed while the infants were sleeping during the quiet sleep phase. For mothers who refused their infants to undergo the surgical procedure, a follow-up of the infants was proposed to verify possible interference of the frenulum with the resting position of the tongue and lips. Infants whose mothers agreed with surgery were referred for lingual frenotomy. Results Regarding the position of the tongue and lips at rest at the initial and final assessments, the statistical analysis demonstrated significant differences between both groups. Conclusion Lingual frenotomy enabled infants diagnosed with ankyloglossia to maintain both tongue coupling against the hard palate and closed lips at rest.

RESUMO Introdução: O surgimento de lesão renal aguda (LRA) em pacientes com síndrome nefrótica (SN) requer diagnóstico imediato e diferenciação entre necrose tubular aguda (NTA) e glomerulonefrite proliferativa. Avaliamos o uso potencial de testes de biomarcadores urinários comerciais no diagnóstico de LRA em pacientes com SN. Métodos: Uma estimativa transversal das concentrações urinárias de KIM-1 e NGAL foi realizada em 40 pacientes com SN: 9 com glomerulopatia proliferativa, sendo 4 com LRA e 31 sem glomerulopatia proliferativa, sendo 15 com LRA. A LRA foi definida usando os critérios da KDIGO. Resultados: A média de idade foi de 35 ± 16 anos. Os principais diagnósticos foram glomeruloesclerose segmentar e focal (10, 25%), glomerulopatia membranosa (10, 25%), doença por lesão mínima (7, 18%), nefrite lúpica (6, 15%) e glomerulonefrite proliferativa (3, 8 %). Os pacientes com NTA apresentaram níveis mais elevados de KIM-1 urinário (P = 0,0157) e NGAL (P = 0,023) do que pacientes sem NTA. As concentrações urinárias de KIM-1 (P = 0,009) e NGAL (P = 0,002) foram maiores em pacientes com LRA do que em pacientes sem LRA. Os níveis urinários de NGAL e KIM-1 foram significativamente maiores em pacientes com NTA sem glomerulonefrite proliferativa do que em pacientes com glomerulonefrite proliferativa (P = 0,003 e P = 0,024, respectivamente). Conclusões: As estimativas de lipocalina associada a gelatinase de neutrófilos (NGAL) e molécula de lesão renal 1 (KIM-1) se correlacionaram com sinais histológicos de NTA, e foram capazes de discriminar pacientes com LRA mesmo em condições de SN. Além disso, os níveis urinários de NGAL e KIM-1 podem ser úteis no diagnóstico diferencial de necrose tubular aguda e glomerulonefrite exsudativa em pacientes com síndrome nefrótica.

ABSTRACT Introduction: Emergence of acute kidney injury (AKI) in patients with nephrotic syndrome (NS) requires prompt diagnosis and differentiation between acute tubular necrosis (ATN) and proliferative glomerulonephritis. We studied the potential use of commercial urinary biomarkers' tests in the diagnosis of AKI in patients with NS. Methods: A cross sectional estimate of urinary concentrations of KIM-1 and NGAL was performed in 40 patients with NS: 9 with proliferative glomerulopathy, being 4 with AKI and 31 without proliferative glomerulopathy, being 15 with AKI. AKI was defined using the KDIGO criteria. Results: The mean age was 35 ± 16 years. The main diagnoses were focal and segmental glomerulosclerosis (10, 25%), membranous glomerulopathy (10, 25%), minimal change disease (7, 18%), lupus nephritis (6, 15%), and proliferative glomerulonephritis (3, 8%). Patients with ATN had higher levels of urinary KIM-1 (P = 0.0157) and NGAL (P = 0.023) than patients without ATN. The urinary concentrations of KIM-1 (P= 0.009) and NGAL (P= 0.002) were higher in patients with AKI than in patients without AKI. Urinary NGAL and KIM-1 levels were significantly higher in patients with ATN without proliferative glomerulonephritis than in patients with proliferative glomerulonephritis (P = 0.003 and P=0.024, respectively). Conclusions: Neutrophil gelatinase associated lipocalin (NGAL) and kidney injury molecule 1 (KIM-1) estimates correlated with histological signs of ATN and were able to discriminate patients with AKI even in conditions of NS. Furthermore, urinary levels of NGAL and KIM-1 may be useful in the differential diagnosis of acute tubular necrosis and exudative glomerulonephritis in patients with nephrotic syndrome.

ABSTRACT Purpose: to verify the psychometric properties - validity and reliability - and the sensitivity, specificity and predictive values of the "Neonatal Tongue Screening Test" from the Lingual Frenulum Protocol for Infants. Methods: this is an experimental retrospective study using data from 100 newborns. The infants were assessed within the first 48 hours after birth using the Neonatal Tongue Screening Test, and subsequently assessed at 30 days of life using the Lingual Frenulum Protocol for Infants. The assessments were performed by examiner 1, who collected images and data to be analyzed by examiner 2. Newborns with lingual frenulum alterations were referred to frenotomy, reassessed 30 days after surgery and followed until six months of life. Data were used for the validation process, which included the analyses of inter-intra rater agreement, criterion validity, construct validity, sensitivity, specificity, positive predictive value, and negative predictive value. Data were statistically treated. The study was approved by the Ethics Committee under the number CAAE 40784315.9.0000.5538. Results: the "Neonatal Screening Test" was able to identify newborns with lingual frenulum alteration and the changes after frenotomy; furthermore, the results demonstrated adequate values of sensitivity, specificity, and predictive values. Concerning inter-intra rater agreement, the consistency of results demonstrated reliability and excellent repeatability. Conclusion: the "Neonatal Tongue Screening Test" has demonstrated to be a valid and reliable assessment tool ensuring accuracy to diagnose lingual frenulum alterations in newborns.

Although the interference of tongue-tie with breastfeeding is a controversial subject, The use of lingual frenotomy has been widely indicated by health professionals.Objective: To observe changes in breastfeeding patterns after lingual frenotomy concerning the number of sucks, pause length between groups of sucking and mother's complaints.Material and Methods : Oral yes/no questions about breastfeeding symptoms and sucking/swallowing/breathing coordination were answered by the mothers of 109, 30 day old infants. On the same day the infants had their lingual frenulum assessed by administering a lingual frenulum protocol. After the assessment, all tongue-tied infants were referred for frenotomy; nevertheless, only 14 underwent the surgery. Of the 109 infants, 14 infants who did not have frenulum alterations were included as controls. Birth order and gender were the criteria for recruiting the control group. The tongue-tied infants underwent lingual frenotomy at 45 days of age. At the conclusion of the frenotomy, the infants were breastfed. At 75 days old, both groups – control and post-frenotomy – were reassessed. Before the reassessment the same oral yes/no questions were answered by the mothers of the 14 infants who underwent frenotomy. The mothers of the control group answered the questionnaire only at the time of the first assessment. Data were subjected to statistical analysis.Results : After frenotomy, the number of sucks increased and the pause length between sucking decreased during breastfeeding. The controls maintained the same patterns observed in the first assessment. From the questionnaire answered by the mothers of the 14 tongue-tied infants, at 30 days and 75 days, we observed that the symptoms concerning breastfeeding and sucking/swallowing/breathing coordination were improved after lingual frenotomyConclusions : after lingual frenotomy, changes were observed in the breastfeeding patterns of the the tongue-tied infants while the control group maintained the same patterns. Moreover, all symptoms reported by the mothers of the tongue-tied infants had improved after frenotomy.

Introduction: in Brazil, chronic hepatitis C in patients coinfected with the human immunodeficiency virus (HIV) is treated with pegylated interferon (Peg-IFN) and ribavirin (RBV). However, few studies have evaluated the effectiveness of this treatment in this particular population. The identification of the factors that predict sustained virological response (SVR) under current clinical practice would enable clinicians to more accurately estimate the probability of achieving an SVR and therefore utilize the appropriate therapeutics, especially in the era of direct-acting antiviral (DAA) agents.Aims: the primary aim of our study was to determine the SVR rate under current clinical practice. The secondary aims were as follows: (1) to determine the factors before and during treatment that predict SVR; and (2) to identify the causes of treatment interruption.Methods:within a cohort of HIV/hepatitis C virus (HCV)-coinfected patients in Brazil, we performed a retrospective analysis of those individuals treated with Peg-IFN and RBV.Results:among the 382 analyzed patients, SVR was observed in 118 [30.9% (95% confidence interval (CI): 26.3-35.8)], which included 25.9% (75/289) of the patients with genotypes 1 and 4 and 48.2% (41/85) of those with genotypes 2 and 3. After multivariate analyses the independent positive predictors for SVR after treatment for chronic hepatitis C with PegIFN and RBV were: absence of an AIDS-defining illness (p= 0.001), HCV viral load lower than 600,000 IU/mL at the onset of treatment (p= 0.003), higher liver enzyme levels (p= 0.039) at baseline, infection with genotypes 2 or 3 (p= 0.003), and no transient treatment interruption (p= 0.001). The treatment was interrupted in 25.6% (98/382) of the patients because of adverse events (11.3%, 43/382), virologic failure (7.8%, 30/382), and dropout (6.5%, 43/382). The main adverse events were cytopenia and psychiatric disorders.Conclusions:in our Brazilian case series, the SVR rate under current clinical practice conditions was similar to that reported in other studies. There was a correlation between an SVR and being infected by genotypes 2 and 3, low viral load, high ALT levels at the onset of treatment, and absence of an AIDS-defining illness. Cytopenia and psychiatric disorders were the major causes of treatment interruption. Efforts should be focused on optimizing management of side effects and counseling to improve adherence and to keep patients on treatment.

This paper presents the treatment protocol of maxillofacial surgery in the rehabilitation process of cleft lip and palate patients adopted at HRAC-USP. Maxillofacial surgeons are responsible for the accomplishment of two main procedures, alveolar bone graft surgery and orthognathic surgery. The primary objective of alveolar bone graft is to provide bone tissue for the cleft site and then allow orthodontic movements for the establishment of an an adequate occlusion. When performed before the eruption of the maxillary permanent canine, it presents high rates of success. Orthognathic surgery aims at correcting maxillomandibular discrepancies, especially anteroposterior maxillary deficiencies, commonly observed in cleft lip and palate patients, for the achievement of a functional occlusion combined with a balanced face.

OBJETIVO: Descrever as mudanças ocorridas após a frenectomia com relação à mobilidade e funções da língua. MÉTODOS: Foram avaliados 53 sujeitos, os quais nunca haviam se submetido a fonoterapia ou a cirurgia do frênulo. Um protocolo com escores específicos para avaliação do frênulo lingual foi utilizado para avaliar os sujeitos com evidências de alteração neste aspecto. Foi encontrada alteração em dez sujeitos, que foram encaminhados a um otorrinolaringologista para frenectomia. Após a cirurgia, esses sujeitos foram reavaliados pelo fonoaudiólogo utilizando-se o mesmo protocolo. Fotos e vídeos foram usados para comparação. RESULTADOS: Trinta dias após a cirurgia, os sujeitos apresentaram a forma da ponta da língua modificada, assim como os movimentos melhorados. O fechamento labial e a fala também melhoraram. CONCLUSÃO: A frenectomia é eficiente para melhorar a mobilidade e a postura da língua, assim como suas funções, incluindo a produção da fala.

PURPOSE: To describe the changes after frenectomy concerning mobility and functions of the tongue. METHODS: Participants were 53 subjects who had never undergone speech therapy or lingual frenulum surgery. A specific lingual frenulum protocol with scores was used by speech-language pathologists when there was evidence of frenulum alteration. Ten subjects had abnormal frenulum and were referred to an otolaryngologist for frenectomy. After surgery, the subjects were re-evaluated using the same protocol. Photos and videos were taken for comparison. RESULTS: Thirty days after surgery, the subjects had the shape of the tip of the tongue and its movements improved. Lip closure and speech were also improved. CONCLUSION: Frenectomy is efficient to improve tongue posture, tongue mobility, oral functions, and oral communication.

Although urinary tract infections (UTI) represent the most common infection caused by enterococci, some aspects remain to be fully clarified. The aim of this study was to determine the clinical characteristics present in UTI caused by Enterococcus spp. in patients followed up at the Prof. Edgard Santos Teaching Hospital of the Federal University of Bahia. All patients consecutively examined between 1997 and 2005, who received a diagnosis of UTI caused by Enterococcus spp. were included in the study. UTI was defined as the presence of 10(5) colony-forming units per mL of urine. Standard microbiological techniques were used. During the study period, 6.2% of the urine cultures were positive for Enterococcus spp. The mean age of the patients was 48.9 years and 57% were male. At initial evaluation, 13% of the patients had complaints suggestive of UTI. Nineteen patients had a history consistent with obstructive uropathy and 26 with neurogenic bladder. At final evaluation, UTI was the diagnosis in 48 patients. In 36 patients (29%), the primary diagnosis was related to urogenital diseases, consisting of obstructive uropathy in 23 of these cases, while in 32 patients (25.8%) primary diagnosis was related to neurologic diseases, frequently neurogenic bladder. UTI caused by Enterococcus spp. is not infrequent, is usually associated with few or no symptoms and occurs in sick patients who have anatomical or functional obstructive uropathy associated or not with urinary tract catheterization or instrumentation. The diagnosis of enterococcal UTI may indicate a urinary tract abnormality yet to be diagnosed.

OBJECTIVE: The present study aims at assessing the occurrence of pyelonephritis and long-term complications in rats submitted to surgical reduction of bladder capacity. MATERIALS AND METHODS: Sprague-Dawley rats were submitted to supratrigonal cystectomy (29 animals) or sham operation (15 animals) and sacrificed 2, 4 and 6 months after the surgical procedure. The arterial blood pressure and serum creatinine levels were assessed before the surgery and at the time of the sacrifice. After the sacrifice a careful inspection of the urinary apparatus was performed to the characterization of the hydronephrosis and for the detection of the presence of calculi. With sterile technique, the urine was aspirated from the bladder and the kidneys removed and sent to a microbiologic study. RESULTS: Pyelonephritis was frequent in animals submitted to supratrigonal cystectomy. The most frequent and isolated microorganisms were Staphylococcus sp. and E. coli. The presence of urinary calculi was correlated significantly to the presence of urinary tract infection (p < 0.003). Arterial hypertension was frequent amongst animals submitted to supratrigonal cystectomy. Serum creatinine was high in 72.4% of the animals in the group submitted to supratrigonal cystectomy. The presence of calculi and pyelonephritis were frequent in rats presenting renal insufficiency and in hypertensive rats. CONCLUSIONS: The long-term course of urinary infection in rats submitted to supratrigonal cystectomy was characterized by a high incidence of renal insufficiency and arterial hypertension that seem to be related to dysfunction and bladder obstruction induced by an extensive surgical procedure and the presence of urolithiasis and pyelonephritis.

OBJETIVO: O ensaio de enzyme-linked immunosorbent assay (ELISA) para a pesquisa de anticorpos anticardiolipina (aCL) é o mais importante teste para o diagnóstico da síndrome antifosfolipídica (SAF). Entretanto esse teste também pode ser positivo em algumas doenças infecciosas. Tem sido sugerido que a detecção de anticorpos para uma mistura de fosfolípides ou para beta2-glicoproteína I (beta2-GP I) teria uma maior especificidade para a SAF que o teste de ELISA-padrão para aCL. O objetivo do presente estudo é comparar a especificidade de três testes para anticorpos antifosfolípides (aFL) em pacientes com doenças infecciosas. MÉTODOS: Anticorpos antifosfolípides foram pesquisados por três técnicas de ELISA, ou seja, o teste-padrão para aCL, o kit de ELISA APhL® e o teste para anti-beta2-GP I em pacientes com doenças infecciosas, tais como sífilis (69), leptospirose (33) e Calazar (30). RESULTADOS: A freqüência de positividade de aFL da classe IgG em pacientes com sífilis, leptospirose e Calazar foi de 13/69 (19%), 9/33 (27%) e 2/30 (6%), respectivamente, com o ELISA-padrão para aCL versus 1/69 (1,4%), 0/33 (0%) e 0/30 (0%) com o kit de ELISA APhL®. A positividade do isotipo IgM foi de 10/69 (14%), 4/33 (12%) e 1/30 (3%), respectivamente, com o ELISA-padrão para aCL, e 1/69 (1,4%), 0/33 (0%) e 0/30 (0%) com o kit de ELISA APhL®. Anticorpos da classe IgG contra beta2GPI foram detectados em 14/69 casos de sífilis (20%), 6/33 casos de leptospirose (18%) e 16/30 casos de Calazar (53%). Assim, o kit de ELISA APhL® apresentou uma maior especificidade: 97% (95% CI: 92%-99%) comparado com 81% (95% CI: 74%-87%) para o teste de aCL-padrão e 72% (95% CI: 64%-79%) para o teste de anticorpos anti-beta2 GPI. CONCLUSÕES: O kit de ELISA APhL® parece ser mais específico para a SAF que o ELISA-padrão para aCL, assim como o teste para anti-beta2GPI. Esse kit pode ser usado para ajudar no diagnóstico e na confirmação da SAF.

OBJECTIVE: The standard enzyme-linked immunosorbent assay (ELISA) for anticardiolipin (aCL) antibodies is the most important test for the diagnosis of antiphospholipid syndrome (APS). However, the test is also positive in some infectious diseases and other non-related syndromes. It has been suggested that the detection of antibodies to a mixture of phospholipids or to beta2-glycoprotein I (beta2-GP I) has higher specificity for APS than the standard aCL ELISA. The aim of the present work is to compare the diagnostic specificity of three different antiphospholipid (aPL) assays in patients with infectious diseases. METHODS: Antiphospholipid antibodies were searched by three ELISA techniques, namely standard aCL, APhL® ELISA kit and anti-beta2-GP I, in sera of patients with infectious diseases, including syphilis (69), leptospirosis (33) and visceral leishmaniasis (30). RESULTS: The frequency of positivity of IgG aPL in patients with syphilis, leptospirosis and Kala-azar was 13/69 (19%), 9/33 (27%) and 2/30 (6%), respectively, using standard ELISA, versus only 1/69 (1.4%), 0/33 (0%) and 0/30 (0%) positivity by the APhL® ELISA kit. The positivity of the isotype IgM aPL was 10/69 (14%), 4/33 (12%) and 1/30 (3%), respectively, by the standard ELISA, and 1/69 (1.4%), 0/33 (0%) and 0/30 (0%) by the APhL® ELISA kit. The presence of significant levels of IgG anti-beta2GPI was observed in 14/69 cases of syphilis (20%), 6/33 cases of leptospirosis (18%) and 16/30 cases of Kala-azar (53%). The APhL® ELISA kit had superior performance showing the highest specificity: 97% (95% CI: 92%-99%) for IgG compared to 81% (95% CI: 74%-87%) for standard ELISA and 72% (95% CI: 64%-79%) for anti-beta2 GPI assay. CONCLUSIONS: The APhL® ELISA kit proved to be significantly more specific than the aCL standard ELISA and the anti-beta2GPI ELISA, and it should be used to help in the diagnosis and confirmation of APS.

OBJETIVO: Identificar a incidência, fatores de risco e mortalidade de insuficiência renal aguda (IRA), em pacientes submetidos à cirurgia para revascularização miocárdica com circulação extracorpórea. MÉTODOS: Estudados prospectivamente todos os pacientes submetidos a cirurgia de revascularização miocárdica e as variáveis clínicas e laboratoriais analisadas através de métodos uni e multivariado (regressão logística). RESULTADOS: Insuficiência renal aguda ocorreu em 16,1% dos 223 pacientes estudados, diálise foi necessária em 4,9% dos pacientes. Os fatores de risco associados à IRA na análise univariada foram: idade > 63 anos OR 3,6 (95% IC=1,6 a 8,3), creatinina sérica pré-operatória > 1,2 mg/dl OR 5,9 (95% IC=2,4 a 14,6), duração da circulação extracorpórea > 90 min OR 2,1 (95% IC=1,0 a 4,4), uso de balão intra-aórtico OR 2,6 (95% IC=1,2 a 5,5); necessidade de drogas inotrópicas OR 4,4 (95% IC=1,9 a 10,2) e, na análise multivariada, foram fatores independentes associados à IRA idade > 63 anos OR 3,0 (95% IC=1,3 a 7,2), creatinina sérica pré-operatória > 1,2 mg/dl OR 4,3 (95% IC=1,6 a 11,4), necessidade de drogas inotrópicas OR 3,2 (95% IC=1,3 a 8,0). A mortalidade nos pacientes com IRA foi de 25,0 % em comparação com 1,1% entre os sem IRA e 63,6% entre os que necessitaram de diálise. CONCLUSÃO: Insuficiência renal aguda em cirurgia de revascularização miocárdica é uma complicação freqüente e está associada à alta mortalidade. Sendo fatores de risco independentes: idade, insuficiência renal prévia e necessidade de drogas inotrópicas.

OBJECTIVE: To identify the incidence, risk factors, and mortality of acute renal failure (ARF) in patients undergoing myocardial coronary artery bypass surgery with extracorporeal circulation. METHODS: All patients undergoing myocardial coronary artery bypass surgery were prospectively studied, and their clinical and laboratory variables were assessed using uni- and multivariate analysis (logistic regression). RESULTS: Acute renal failure occurred in 16.1% of the 223 patients studied; 4.9% of patients required dialysis. Risk factors associated with ARF in the univariate analysis were age > 63 years, OR 3.6 (95% CI=1.6 to 8.3); preoperative serum creatinine > 1.2 mg/dL, OR 5.9 (95% CI=2.4 to 14.6); duration of extracorporeal circulation > 90 min, OR 2.1 (95% CI=1.0 to 4.4); use of intraaortic balloon, OR 2.6 (95% CI=1.2 to 5.5); need for inotropic drugs, OR 4.4 (95% CI=1.9 to 10.2). In the multivariate analysis, independent factors associated with ARF were: age > 63 years, OR 3.0 (95% CI=1.3 to 7.2); preoperative serum creatinine > 1.2 mg/dL, OR 4.3 (95% CI=1.6 to 11.4); need for inotropic drugs, OR 3.2 (95% CI=1.3 to 8.0). Mortality in the patients with ARF was 25.0% compared with 1.1% in those without ARF and 63.6% in those who required dialysis. CONCLUSION: Acute renal failure after myocardial coronary artery bypass surgery is a frequent complication associated with a high mortality rate. The independent risk factors are age, previous renal failure, and the need for inotropic drugs.

OBJETIVO: Avaliar se a hipertensão arterial (HA) diagnosticada durante os primeiros dois meses de acompanhamento associa-se com a incidência de doença renal terminal (DRT) em negros e mulatos com glomerulonefrite, levando em consideração a idade, o sexo e o diagnóstico histológico. MÉTODOS: Estudo de coorte retrospectivo baseado em uma amostra de 120 pacientes negros e mulatos: 26 com glomerulonefrite membranoproliferativa (GNMP), 58 com glomeruloesclerose segmentar e focal (GSF) e 36 com outros tipos de glomerulonefrites (OTGN). HA foi considerada presente em pacientes usando anti-hipertensivos, em adultos apresentando média de três medidas de pressão arterial (PA) sistólica igual ou superior a 140 ou média das correspondentes medidas da PA diastólica igual ou superior a 90 mmHg. Para a faixa etária igual ou inferior a 18 anos foram utilizados os critérios da "Task Force on Blood Pressure in Children". RESULTADOS: HA no início do acompanhamento foi diagnosticada em 48 dos 120 pacientes (41,6%). A incidência de DRT foi aproximadamente 2,6 vezes maior em pacientes hipertensos (risco relativo (RR) = 2,62; intervalo de confiança (IC) 95% =1,01-7,03; p=0,031). A associação entre HA e aumento da incidência de DRT foi similar entre o grupo com idade menor ou igual a 18 anos e o grupo com idade superior a 18 anos. Mesmo após o ajuste para idade, sexo e tipo histológico, a incidência de DRT permaneceu maior (e marginalmente significante) em hipertensos que em normotensos (RR ajustado =2,15; IC 95%=0,86-5,39; p=0,07). CONCLUSÕES: De acordo com os resultados, detecção precoce de HA em negros e mulatos com glomerulonefrite ajuda a identificar pacientes com maior risco de DRT, independente da idade, do sexo e do tipo histológico. Outros trabalhos são necessários para determinar em que extensão a severidade e grau de controle da HA contribuem para o desenvolvimento de DRT em negros e mulatos com glomerulonefrite.

OJECTIVE: To assess whether hypertension diagnosed during the first two months of follow-up is associated with the incidence of end-stage renal disease (ESRD) in negroes and mulattoes with glomerulonephritis after taking into account age, gender and the histological diagnosis.METHODS: A retrospective cohort study based on a sample of' 120 negro and mulatto patients with glomerulonephritis, 26 with membranoproliferative glomerulonephritis (MPGN), 58 with focal segmental glomerulosclerosis (FSG) and 36 with other types of glomerulonephritis (OTGN). Hypertension was considered present if antihypertensive treatment was used, in adults (age >18 years) with a mean of the three first systolic blood pressures of 140 mmHg or a mean of the corresponding diastolic blood pressure of 90 mm Hg or greater. For ages equal to or below 18 years the criteria recommended by the "Task Force on Blood Pressure in Children" were used.RESULTS: Hypertension was diagnosed in 48 of the 120 patients (41.6%). The incidence of ESRD was approximately 2.6 times higher in hypertensive patients (relative risk(RR)=2.62; 95 % confidence interval (CI) =1.01-7.03, p=0.031). This association between hypertension and higher risk of ESRD was similar between the group younger than 19 and the group older than 18 years. Even after adjusting for age, gender and histologic type, the incidence of ESRD remained higher (and marginally significant) in the hypertensive than in the normotensive group (adjusted RR=2.15; IC 95%=0.86-5.39, p=0.07).CONCLUSIONS: According to the findings, early detection of hypertension in negroes and mulattoes with glomerulonephritis helps to identify patients with higher risk of ESRD, independently of age, gender and histologic type. Further research is needed to determine to what extent the severity of hypertension and the degree of blood pressure control contribute to the development of ESRD in negroes and mulattoes with glomerulonephritis.

An experience aiming to promote a residue interchange and recovery between the teaching laboratories of the Chemistry Institute of this University is described. At the present, several residues interchange have already appeared as advantageous. To make the work easier, a software has been developed in order to keep a record of all the residues generated by the teaching laboratories. Standard labels have been developed for the residues in order to organize them. The software and the label design are described.

As formas severas de esquistossomose mansônica, particularmente a hépato-esplênica, se acompanham de glomerulopatia geralmente manifesta por síndrome nefrótica. Nos últimos 10 anos reduziu-se muito o número de casos observados desta glomerulopatia no Hospital Universitário Prof. Edgard Santos, um hospital geral num estado onde esta parasitose é endêmica. O objetivo deste estudo foi verificar se estava havendo, de fato, desaparecimento desta patologia ou se este número decrescente refletia apenas diminuição marcante de casos graves de esquistossomose mansônica acompanhados neste Hospital. Para isso foram comparadas as prevalências de glomerulopatia em hepatosplênicos esquistossomóticos autopsiados no Hospital Universitário Prof. Edgard Santos em duas décadas: de 1960-70, antes da intervenção terapêutica nas áreas endêmicas de esquistossomose com oxamniquine, e de 1980-1990, após a adoção desta intervenção. Houve grande redução no número de doentes com hepatosplenomegalia esquistossomótica autopsiados no Hospital Universitário Prof. Edgard Santos quando comparadas a década antes (140 autópsias) e depois (31 autópsias) do tratamento com oxamniquine. A prevalência de glomerulopatia, entretanto, persistiu a mesma (11,4% comparada com 12,9%, respectivamente). A conclusão é que a redução do achado de glomerulopatia esquistossomótica em nossos dias reflete apenas a redução das formas graves da parasitose após a intervenção terapêutica nas áreas endêmicas.

Hepatosplenic form of S. mansoni infection may be accompanied by a glomerulopathy in 12-15% of cases, manifested in the majority by a nephrotic. This type of renal involvement is becoming a rare occurrence in our University Hospital (Hospital Universitário Prof. Edgard Santos) a typical general hospital in an endemic state for this parasitic disease. To investigate this fact, autopsied cases with patients with hepatosplenic form of schistosomiasis mansoni during two decades in our Hospital - 1960-70, (before a therapeutic intervention in endemic areas with oxamniquine) and 1980-1990 (after the intervention) were compared in reference to number of cases and the finding of glomerulonephritis by histological examination. Even though there was a strinking decrease in number of patients with advanced forms of this disease (140 as compared to 31 autopsies in these two decades), the prevalence of glomerulonephritis diagnosed was 11.4 (16 cases) in the first and 12.9 (4 cases) in the second. As there was no change in pattern of attendance in this Hospital, the drastic decrease in number of severe forms of this parasitic infection following massive therapy of the endemic population with oxamniquine in the most likely explanation not only for the decrease in number of hepatosplenic cases but, also, and as a consequence, the scarcity of cases of the schistosomal glomerulopathy observed.

Leptospirose é uma importante causa de insuficiência renal aguda, em nosso ambiente. Embora vários sejam os mecanismos implicados, o papel da rabdomiólise na patogênese da insuficiência renal aguda na leptospirose ainda não foi analisado. Com esse objetivo, 16 pacientes com o diagnóstico da forma icterohemorrágica da leptospirose consecutivamente admitidos no Hospital Couto Maia, Salvador, Bahia, foram prospectivamente estudados. A doença foi caracterizada por início súbito e, à admissão, ictericia, sufusões hemorrágicas conjuntivais e mialgias. Proteinúria de intensidade média a moderada com sedimento urinário inexpressivo foi observada em 37,5% dos pacientes e níveis séricos elevados de uréia e creatinina em 78,5% e 74,0%, respectivamente. Níveis aumentados de aminotransferase foram documentados em todos os 12 e de CPK em todos os 10 pacientes avaliados para essas enzimas. Níveis séricos maiores que 120µg/l foram observados em 56,2% dos pacientes. Não foram encontradas correlações, entretanto, entre mioglobinemia e insuficiência renal em gravidade da leptospirose.

Leptospirosis is an important cause of acute renal failure in our environment. Although several mechanisms are implicated, the role of rhabdomyolysis in the pathogenesis of acute renal failure in leptospirosis has not been analysed. Sixteen patients with the diagnosis of leptospiroses consecutively admitted to the hospital were prospectively studied. The disease was characterized by sudden onset in all patients and, at admission, jaundice, conjunctival suffusion and myalgias. Mild to moderate proteinuria with unremarkable urinary sediment was recorded in 37.5% of the patients and abnormal levels of urea creatinine were found in 87.5% and 74.0%, respectively. Increased levels of aminotranspherase were documented in all 12 and CPK in all 10 patients studied. Serum myoglobin levels greater than 120µg/l recorded in 56.2%. A correlation between myoglobin and renal failure or severity of disease, however, could not be established.
