Este trabalho foi realizado para verificar se a ultra-sonografia do pâncreas oferece dados auxiliares na classificação de diabéticos adultos dos tipos 1 e 2. O tamanho e a ecogenicidade do pâncreas foram determinados pela ultra-sonografia em 81 diabéticos, sendo 20 do tipo 1 e 61 do tipo 2 (53 obesos e oito não-obesos). Os pacientes tipo 2 obesos diferiram dos demais por apresentarem área total e diâmetro ântero-posterior do corpo do pâncreas significativamente maiores. Quanto à ecogenicidade pancreática, esta estava aumentada com maior freqüência nos diabéticos tipo 2 obesos que nos diabéticos tipo 1. Consideramos, assim, que a ultra-sonografia do pâncreas constitui metodologia auxiliar na classificação de diabéticos entre os tipo 1 e 2, sendo menos eficaz quando os últimos não são obesos.

OBJETIVO: O excesso de peso é um grande problema de saúde pública em todo o mundo, atingindo crianças e adolescentes. O presente estudo teve por objetivo verificar se a condição de portador de sobrepeso se associa à presença de fatores de risco à saúde. MÉTODOS: Foram estudados 84 sujeitos entre seis e 17 anos, constituindo-se um grupo de 34 pacientes portadores de sobrepeso e outro de 50 obesos, atendidos em ambulatório de Nutrologia Pediátrica da Universidade de Ribeirão Preto (Unaerp), durante o período de outubro de 2004 a outubro de 2005. Foram obtidas as variáveis: pressão arterial, circunferência abdominal, glicemia de jejum, glicemia de segunda hora, colesterol total, HDL-c, LDL-c e triglicérides. Comparam-se os dois grupos por meio de duas abordagens estatísticas: comparação entre as distribuições dos valores absolutos (teste de Mann-Whitney) e entre as frequências de valores considerados alterados (teste exato de Fisher). RESULTADOS: Quanto à primeira abordagem, verificou-se diferença estatística apenas para o HDL-c, com maiores valores para o subgrupo de portadores de sobrepeso de seis a dez anos. Quanto à segunda comparação, verificou-se diferença estatística para a circunferência abdominal (segundo os critérios de Freedman), HDL-c e glicemia de jejum, com maiores frequências de valores alterados entre os obesos. CONCLUSÕES: Os portadores de sobrepeso apresentaram alterações indicativas de prejuízos à sua saúde, semelhantemente aos obesos, sendo necessário também incluí-los nos programas de prevenção e tratamento.

Purpose. To evaluate the effects of captopril (Cpt) on carbohydrate metabolism and growth hormone (GH) in adults hypertensive obese patients with normal (NGT) or impaired (IGT) glucose tolerance and left ventricular hypertrophy. Methods. Ten patients (53 ± 8 years), 8 women and 2 men, white, body mass index (BMI) ≥ 26 kg/m2, left ventricular mass index (LVMI) > 135 g/m2 in man and > 110 g/m2 in woman, with diastolic blood pressure (DBP) 95-115 mmHg after 3 weeks of placebo, were identified by oral glucose tolerance test (OGTT-75 g) as either with NGT or IGT, and treated with Cpt 25 mg t.i.d. for 8 weeks. At the 8 weeks, dosage was increased to 50 mg b.i.d. if DBP > 90 mmHg or the decrease of the DBP < 10%, during the next 8 weeks. OGTT and clonidine tests (0,04 mg/kg) with determinations, every 30 minutes of glucose, insulin, and GH during 2 hours, were performed. Results. Cpt lowered SBP and DBP in the NGT group and IGT group. The LVMI and the left ventricular mass (LVM) decreased in the IGT group with no significant change in the NGT group. Cpt promoted in the IGT group decrease in the area under the curve (AUC) of glucose, and AUC of insulin, with increase of the AUC of the percent of the β cell function, AUC of HC, and insulin sensitivity index with no significantly change in the NGT group. Conclusion. Adults hypertensive obese patients with IGT had decreased significantly in mean fasting level of GH concentrations compared to age, race, and BMI matched hypertensive patients with NGT. Treatment with Cpt induced a significant increased of the GH, with improvement of the metabolism in patients with IGT.

Laryngeal Electromyography (LEMG) is an auxiliary diagnostic method used for the comprehension and diagnosis of different neurological diseases that compromise laryngeal function. The most common LEMG technique is the percutaneous insertion of needle electrodes guided by surface anatomical references. We describe techniques for inserting needle electrodes into the tireoaritenoideus (TA), cricotireoideus (CT), cricoaritenoideus lateralis (CAL) and cricoaritenoideus posterioris (CAP) muscles; these are used at UNICAMP laryngology ambulatory; we discuss difficulties found and their proposed solutions. All patients were submitted to otorhinolaryngological, phonoaudiological and laryngeal endoscopy before LEMG. The CAP approach, by digital rotation of the thyroid cartilage was found to be the most difficult, followed by the CAL approach. TA and CT approaches gave no major problems, except with some older and obese patients. A significant complication of the TA approach via thyroid cartilage was a hematoma in one patient which partially obstructed the laryngeal lumen.

PURPOSE: To evaluate the importance of the oral glucose tolerance test for the diagnosis of glucose intolerance (GI) and type 2 diabetes mellitus (DM-2) in women with PCOS. METHODS: A retrospective study was conducted on 247 patients with PCOS selected at random. The diagnosis of GI was obtained from the two-hour oral glucose tolerance test with 75 g of glucose according to the criteria of the World Health Organization (WHO) (GI: 120 minutes for plasma glucose =140 mg/dL and <200 mg/dL), and the diagnosis of DM-2 was obtained by both the oral glucose tolerance test (DM: 120 minutes for plasma glucose =200 mg/dL) and fasting glucose using the criteria of the American Diabetes Association (impaired fasting glucose: fasting plasma glucose =100 and <126 mg/dL; DM: fasting glucose =126 mg/dL). A logistic regression model for repeated measures was applied to compare the oral glucose tolerance test with fasting plasma glucose. ANOVA followed by the Tukey test was used for the analysis of the clinical and biochemical characteristics of patients with and without GI and/or DM-2. A p<0.05 was considered statistically significant. RESULTS: PCOS patients had a mean age of 24.8±6.3, and body mass index (BMI) of 18.3 to 54.9 kg/m2 (32.5±7.6). The percentage of obese patients was 64%, the percentage of overweight patients was 18.6% and 17.4% had healthy weight. The oral glucose tolerance test identified 14 cases of DM-2 (5.7%), while fasting glucose detected only three cases (1.2%), and the frequency of these disorders was higher with increasing age and BMI. CONCLUSIONS: The results of this study demonstrate the superiority of the oral glucose tolerance test in relation to fasting glucose in diagnosing DM-2 in young women with PCOS and should be performed in these patients.
