Incidência e tratamento dos cistos.

The records of 78 patients (1978-1987 period) submitted to surgical treatment of cysts, were analysed to verify the cyst location, etiology, types of cysts, and surgical techniques. There were made commentaries and orientations on the necessity of radiography, cytological and histopathological examination and post-operative radiological control.

Tratamento endurecedor para cones de guta-percha.

The subject of this work was to study a hardening procedure for gutta-percha points, in order to make ease their introduction in very curved root canals. Gutta-percha points of different brands and dimensions were submitted to treatment with alcohol 96 degrees for 1 to 3 days. After this treatment the weight necessary to make a bending of 35 degrees on the tip of the gutta-percha was evaluated. The obtained results were submitted to statistic analysis and the following conclusions can be observed: a. The treatment with alcohol make hard the gutta-percha points in a significant level. b. There was not significant differences between the results obtained with more than one day of alcohol treatment. c. The treatment with alcohol do not make hard all the brands of gutta-percha points.

Implicações nutricionais no tratamento e recuperação de pacientes adultos com diarréia crônica.

The nutritional assessment by 24 hour-dietary recall, anthropometry and blood-components measurements was undertaken in 23 adult patients, 17 males and 6 females suffering of chronic diarrhea from pancreatitis (30%), inflammatory bowel disease (22%), short intestine syndrome (9%) and unknown diarrhea (35%). The nutritional assessment was done at the entry and repeated at the discharge of the hospitalization that averaged 35 days, during which the patients received specific medical treatment along with obstipating diets. The hospitalization resulted in overall improvement of the patients either clinically by reducing their defecation rate or nutritionally by increasing their protein-energy intake and the values of anthropometry and blood components (albumin, free-tryptophan and lymphocytes). When the patients where divided into two groups based on their fecal-fat output one could note the better nutritional response of the group showing steatorrhea than the non-steatorrhea group, with the serum albumin and the arm-muscle circumference being discriminatory between groups. However even in the better recovered patients the indicative values of a satisfactory nutritional status were not accomplished. Thus, these data suggest that besides the overall nutritional improvement seen in the studied chronic diarrhea patients the full-nutrition recovering would demand either or both a longer hospitalization and/or an early-aggressive nutritional support.

Obstrução nasolacrimal congênita - Diagnóstico e tratamento

Patients with congenital nasolacrimal obstruction (CNLO) were evaluated at the Lacrimal Apparatus Service of Botucatu Faculty of Medicine - UNESP from 1990 to 1993. 45 children were seen at this period with CNLO. The diagnosis was confirmed by dacryocystography (DCG). Obstruction was unilateral in 77,7% of the patients; 68,1% at Arlt Sinus and 43,6% had lacrimal sac grade 1. Probing was made in children older than 6 months, under general anaesthesia, after DCG was performed. Cure was greater in children age 6 to 12 months with obstruction at Hasner's Valve and without dilation of lacrimal sac.

ESTUDO COMPARATIVO DUPLO-CEGO DA EFICACIA E SEGURANCA DO CILAZAPRIL COMPARADAS A NIFEDIPINE 'RETARD' NO TRATAMENTO DA HIPERTENSAO ARTERIAL LEVE E MODERADA

Purpose: To evaluate the antihypertensive efficacy and safety of cilazapril compared to nifedipine retard in mild to moderate hypertension. Methods: Forty randomized out-patients with mild moderate hypertension, diastolic pressure (DP) between 95 and 115 mmg/Hg, with placebo for 15 days were randomized and allocated for treatment, double-blind, once daily with cilazapril 2.5 mg (n = 20) or nifedipine retard 20 mg (20 = n) for four weeks. The non-responders (DP > 90 mmHg) had the dosage increased twice, b.i.d., while responders were maintained up to 10 weeks. Clinical visits were performed before, at baseline and every two weeks and the laboratory test was performed after placebo run-in, 4th and 10th weeks of treatment. Results: The blood pressure (BP) were similar between groups at the end of the placebo (cilazapril 151 ± 14/103 ± 5 - nifedipine 157 ± 17/108 ± 7 mmHg, p > 0.05). DP decreased already at second weeks (cilazapril 95 ± 9 - nifedipine 96 ± 11 mmHg, p < 0.05, compared to week 0) in both groups at the end of study with no differences inter groups. BP normalization was obtained in 58% of the patients with cilazapril and in 61% in the nifedipine group. Adverse biochemical effects were not observed in any group. Six (16%) patients of the cilazapril and 15 (39%) of nifedipine related collateral events, although no difference were observed between groups. Conclusion: Cilazapril 2.5 to 5 mg normalized BP in 58% of mild and moderate hypertension patients, and this efficacy was similar to sustained-release nifedipine 20 to 40 mg. Cilazapril had no adverse effects on the biochemical parameters with low incidence of collateral effects.

TRATAMENTO DA HIPERTENSAO ARTERIAL LEVE E MODERADA COM FOSINOPRIL. COMPARACAO DE EFEITOS ADVERSOS COM OUTROS ANTI-HIPERTENSIVOS

Purpose - To evaluate the adverse reactions of fosinopril with other antihypertensives used as monotherapy. Methods - Out-patients (n = 2,568) with diagnostic of mild to moderate hypertension, diastolic blood pressure (DBP) 95-115 mmHg, with no antihypertensive treatment for 15 days, were included to treatment initially with fosinopril (F) 10mg, once daily, for six weeks. After this period, patients with DBP >95mmHg had the dosage, once daily, increased to 20 mg, while the others were maintained with the same dosage for six more weeks. Adverse reactions of 822 patients treated as monotherapy were grouped as absent, musculoskeletal, cardiovascular, cough, gastrointestinal, neurological, genital-urinary dysfunctions and dermatological and compared with 1,568 with F. Monotherapy consist in α-methyldopa (100 patients); β-blocker (129); calcium blocker (106); diuretic (394); and another ACE inhibitors (93). Results - At the end of the period without treatment, the blood pressure (BP), 165 ± 16/105 ± 7 mmHg decreased significantly at 6(th) week to 144 ± 15/91 ± 9 mmHg (p < 0.05 vs week 0) with further lowering to 139 ± 13/86 ± 7 mmHg till the end of 12(th) week. BP response (DBP ≤90 mmHg) was obtained in 89% of the patients with F. Absence of adverse reactions were ≥70% in patients with F compared to other drugs. Conclusion - Fosinopril has demonstrated therapeutic efficacy and less adverse reactions compared to antihypertensives used previously as monotherapy.
