[Presence of antibiotics in pasteurized milk distributed in Costa Rica hospital nutrition services].

Two hundred samples of pasteurized milk collected from nutrition services of ten hospitals in Costa Rica, were evaluated for the presence of antibiotics residues. Bacterial inhibitory growth test were used to detect inhibitory substances. It was found that 13% (N = 200) of the samples were contaminated, with variations from 0% to 35% (N = 20) in the different hospitals tested. The larger number of positive samples corresponds to lactic industries that supply 70% of the hospital's requirements of pasteurized milk.

Epidemiology of inflammatory bowel disease in the Province of Granada, Spain: a retrospective study from 1979 to 1988.

An epidemiological study of inflammatory bowel disease in the Province of Granada, Spain, was conducted between 1979 and 1988. Altogether, 257 cases were identified: 167 ulcerative colitis, 79 Crohn's disease, and 11 indeterminate colitis. The mean incidence of ulcerative colitis in the 10 year period was 2/10(5) and 0.9/10(5) for Crohn's disease. This is the first epidemiological study in Spain of the incidence of ulcerative colitis and corroborates the results of an earlier population based study on the incidence of Crohn's disease in Spain.

Plasmodium falciparum proteinases and red blood cell invasion.

Malarial proteinases of the erythrocytic life-cycle are used to design new inhibitors capable of blocking the parasite's development. The Merozoite Proteinase for Erythrocytic Invasion (MPEI) of Plasmodium falciparum, a neutral proteinase, and the acidic Pf37 proteinase acting on spectrin as substrate, are good candidates for this kind of strategy.

[An analysis of the obligatory reporting of meningitis in a pediatric area].

AIMS: To find out the validity, reliability and quality of the epidemiological information which comes from the System of Statutory Declarations. The example used is the incidence of Meningitis. DESIGN: Descriptive study of the coverage of the Declaration, with the help of the EDO (Illnesses requiring a Statutory Declaration) index, of the pediatric (up to 14 years old) cases of meningitis attended in our Area between 1984 and 1989. We analysed how the Declaration had been filled in and the agreement between the information gathered through the notification system and clinical records. SITE. The whole network of epidemiological vigilance: hospitals, provincial epidemiological services and primary care services. PATIENTS: All the cases of child meningitis (120 cases) seen in the Mother and Child Hospital in our area between 1984 and 1989. MAIN MEASUREMENTS AND RESULTS: The meningitis declaration covered 47.5% of the total number of cases seen. In the cases declared, the diagnosis of meningococcal meningitis on the EDO index was 89.5%, whereas the rate in the clinical reports was only 20%. Thus agreement in the diagnosis does not exceed what could be produced by chance (Kappa = 2.5%; p = NS), as agreement for all diagnoses is 7.1%. CONCLUSIONS: Our results demonstrate a low level of declaration, poor standard of compliance and scant agreement between the Statement of Declaration and the clinical report. The validity and reliability of this information is extremely low and suggests a need to re-consider the usefulness of this vigilance system for health-service practice, especially in Primary Health Care.

Lovastatin in the treatment of hypercholesterolemia in CAPD.

The authors studied the effect of lovastatin on five hypercholesterolemic CAPD patients with high risk of atherosclerotic cardiovascular disease. Patients took lovastatin 20 mg once daily for a mean period of 4.5 months. Pre- and post-treatment values of LDL and VLDL totals (325 mg/dl and 292 mg/dl, respectively) and of HDL (42 mg/dl and 43 mg/dl, respectively) had no significant statistical difference. Lack of significance may be due to low number of patients and short trial time. The study did demonstrate that lovastatin is well tolerated in CAPD patients.

[Gastric metastasis of renal cell adenocarcinoma].

Gastric metastases are rare, usually discovered at autopsy. The most frequent ones are breast and bronchial cancer, as well as malignant melanoma. The case of a patient with upper gastroenterological hemorrhage due to an ulcerated metastasis from a renal cell carcinoma is presented.

Once weekly subcutaneous erythropoietin is an effective maintenance therapy in the treatment of anemia of end stage renal disease in patients on CAPD.

The efficacy of once weekly subcutaneous erythropoietin (SC EPO) was evaluated by reviewing records of twelve continuous ambulatory peritoneal dialysis (CAPD) patients age 27-66 years after achieving a goal hematocrit (hct) greater than 30%. Patients had a mean hct of 22.8% (range: 19.1-29.5) and were placed on a thrice weekly SC EPO dose of 4000 international units (IU) (37-74 IU/KG, [mean of 57 IU/kg]) until a goal hct greater than 30% was achieved. This hct ranged from 30.8-37% (mean 33.2%) and was achieved in a mean of 11.5 weeks (range: 4.1-29 weeks). Patients were then maintained on the same SC EPO dose given only once weekly. 11/12 (92%) patients have maintained a mean hct of 34% (range: 29-38.4%) on once weekly SC EPO over a mean period of 14 weeks (range: 1.4-36 weeks). The mean serum ferritin was 484; only two patients required parenteral iron dextran therapy. One patient did not reach the goal hct due to poor compliance. There was no significant increase in blood pressure or in serum potassium level. We conclude that SC EPO is effective in treating anemia in these patients and can be given once weekly to maintain a hct greater than 30%.

Mannose-resistant hemagglutination, enzyme-linked immunosorbent assay, and immune electron microscopy for detection of K99 fimbrial antigen in Escherichia coli from calves.

Mannose-resistant hemagglutination (MRHA) was evaluated for identification of Escherichia coli with K99 fimbriae. The sensitivity and specificity of MRHA, relative to the enzyme-linked immunosorbent assay, were 21 and 79%, respectively. Disagreement between the tests may have been due in part to separation of pili from the cells, with resultant enzyme-linked immunosorbent assay-positive, MRHA-negative tests. MRHA was not useful as the sole means for the identification of E. coli with K99 fimbriae.
