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.

EFICACIA E TOLERABILIDADE DA ASSOCIACAO CAPTOPRIL + HIDROCLOROTIAZIDA NO TRATAMENTO DA HIPERTENSAO ARTERIAL LEVE A MODERADA. ESTUDO MULTICENTRICO

Purpose. To evaluate the antihypertensive efficacy and tolerability of captopril 50 mg + hydrochlorothiazide 25 mg daily in mild to moderate primary hypertension. Methods. Out-patients (n = 471) with mild to moderate hypertension, diastolic blood pressure (DBP) 95-115 mmHg, with 15 days of washout, were included to the treatment initially with half tablet of the association of captopril 50 mg + hydrochlorothiazide 25 mg once daily, for 30 days. After this period, patients with DBP > 90 mmHg had the dosage duplicated, while the others had the same dosage for 60 days more. Evaluation was performed 15 days before and then every month during active drug. Results. Twenty six patients were withdrawn, 13 (2,7%) by adverse effects and 13 by protocol violation. At the end of the wash-out period, the blood pressure (BP), 162 ± 16/103 ± 6 mmHg decreased significantly at the 30th day to 146 ± 14/92 ± 8 mmHg (p < 0,001 vs 0th day); 139 ± 12/86 ± 7 mmHg at the 60th day, (p < 0,001 vs 30th day), and further to 136 ± 11/84 ± 5 mmHg (p < 0,001 vs day 0) till the end of the 90th day. Antihypertensive efficay (DBP ≤ 90 mmHg and decreased for the DBP ≥ 10 mmHg) was obtained in 82% of the patients. There was no difference in BP control considering race, hypertension level, previous antihypertensive treatment and obesity. Cough (4%) was the main adverse event. Conclusion. Captopril + hydrochlorothiazide was effective and safe in the treatment of mild to moderate hypertension. The favorable response was observed in 82% of the patients independently of race, hypertensive level, previous antihypertensive treatment and obesity. Low incidence of side effects was reported, with no difference from others reported in the literature.

Estreptomicina aumenta a aderência em células epiteliais de Bacteroides melaninogenicus associado às lesões peridentárias da cara inchada dos bovinos

Cara inchada of cattle (CI) is a periodontitis which occurs in calves in several regions of Brazil. Its progressive lesions, caused mainly by Bacteroides melaninogenicus and Actinomyces pyogenes, could lead to loss of teeth, malnutrition and possibly death of affected animals. For further analysis of the pathogenesis of this disease the influence of streptomycin on the adherence of the causative bacteria to oral epithelial cells of cattle was determined. Production of streptomycin by soil bacteria (Actinomycetes) in Brazil had been suggested by several authors. In our studies, streptomycin in subinibitory concentrations increased tenfold the rate of adherence with B. melaninogenicus (from 0.4 to 4.0 bacteria per bovine epithelial cell). On the contrary, streptomycin did not influence significantly the adherence of A. pyogenes nor streptococci of the viridans group. Thus, streptomycin could be a contributing factor to the development of the periodontal infections with B. melaninogenicus.

Fortificação do leite fluido na prevenção e tratamento da anemia carencial ferropriva em crianças menores de 4 anos

The effectiveness of the use of chelate aminoacid iron fortified fluid milk in the treatment of iron deficiency in children under four years of age was studied. The 269 children included in this trial received 1 liter/day of fluid milk fortified with 3 mg of chelate aminoacid iron and were evaluated at six monthly intervals. At the beginning of the study 62.3% of the children presented anemia. After 6 months, this percentage had decreased to 41.8% and at the end of one year to 26.4%. The greatest decreases occurred in the groups comprising the subjects who were of 12 to 23 months of age and those under one year of age. Among the children who presented initial hemoglobin levels under 9.5 g/ dl, 59.3% were free of anemia after one year of follow-up. Of those presenting initial hemoglobin levels between 9.5 and 10.9 g/dl, 66.7% recovered from their anemia. There was also greater hematological improvement in the children that ingested over 750 ml/day of fortified milk in those families that did not share the supply of supplement among their other members and in those families that had only one child under five years of age. These findings led to the conclusion that the fortification of fluid milk is a viable and effective method for the treatment of iron deficiency in pre-school children.

Tratamento de ulcera varicosa e lesoes de pele com Calendula officinalis L. e/ou com Stryphnodendron barbadetiman (Vellozo) Martius

Calendula officinalis L. and S. barbadetiman are used in Brazil for the treatment of a number of aliments. The healing properties of these substances are well known, mainly in domestic or sun burn. In order to establish a pharmacological rationale for the traditional use of these plants as a cicatrizant or antiinflammatory remedy, we used ethanol extracts or gel from stem bark of the S. barbadetiman and inflorescence of the Calendula. We selected four groups of patients; two groups shown varicose ulcer (I, II) and two groups shown skin lesions (III and IV). Groups I and III were treated with Calendula and group II and IV were treated with Calendula plus barbadetiman. The data in this study suggest that the treatment with Calendula or Calendula plus barbadetiman are effective in the process that brings wounds to a close. These findings provide basis to an alternative treatment of varicose ulcer.

Efeitos do tratamento oral com sulfato de vanadila em ratos diabeticos jovens

This work intends to evaluate the effects of oral vanadyl treatment (VOSO 4, 1 mg/mL) in young streptozotocin-diabetic rats during 19 and 29 days. In several times of treatment the rats were monitored to determine body weight, food and water intakes, glycemia, and the urinary excretion of glucose and urea. The animals were killed in the 19(th) and 29(th) days, and the glycemia level was determined again, as well as the weight of pancreas, muscles (Soleus and Extensor digitorum longus - EDL) and adipose tissues (epididymal and retroperitoneal). The results showed that the treatment of young diabetic rats with VOSO 4 promotes the reduction of hyperglycemia (p < 0.01), food (p < 0.01) and water intakes (p < 0.05) and body weight (p < 0.05). Neither the tissues and pancreas weights nor the urinary urea level of the treatment group varied in comparison to the control group. In conclusion, the vanadyl treatment in the studied period is able to reduce the main metabolic alterations often found in diabetes. These data are very useful and important for the future experiments to verify the effects of vanadyl sulfate on muscle protein metabolism in diabetic rats.
