[Improving home auto-control in diabetic children: reducing atherogenic risk].

UNLABELLED: Insulin-dependent Diabetes (IDDM) is a major endocrine abnormality in children and the greatest morbi-mortality problems for diabetic patients are those related to cardiovascular complications (macro-microangiopaties), where kept hyperlipidemia and hyperglucemia play a fundamental patogenic role. The programs for optimization of home autocontrol have reduced frequent metabolic derangements. The aim of this study was to analyze the metabolic control state and its relationships with plasma lipids and atherogenic ratios in diabetic patients that were submitted to a program for optimization of home autocontrol of this illness. MATERIAL AND METHODS: Blood samples were taken fom 49 IDDM, aged 10.53 +/- 0.51 (+/- SEM) years old, with a mean evolution period of 4.34 +/- 0.38 years, at the begining of the program (Stage I) and 6 months later (Stage II). Biochemical Analysis: Total Cholesterol (TC), cholesterol joined to high density lipoprotein (HDLc), Triglycerides (TG) and Phospholipids (Ph) were measured by microspectrphotometric methods. Cholesterol joined to very low and low density lipoproteins (VLDLc and LDLc, respectively) were calculated by Friedwald's formula. Apoproteins A and B (Apo A and Apo B) were measured using Mancini's method, Glycemia levels (Gly) by peroxidase's method, Glycosilated Serum Protein (GSP) by colormetric's method and Glycosilated haemoglobine (HbA1c) by chromatographic separation using cationic interchange microcolumns. RESULTS: 65% of the patients showed a significant decrease in plasma levels of Gly, GSP and HbA1c percentage between Stages I and II (Favourable Metabolic Control).(ABSTRACT TRUNCATED AT 250 WORDS)

[Cancer and adolescence].

Since 1977, 64 children were diagnosed with cancer in the Department of Pediatrics of the University of Granada. Incidence and mortality rates from specific tumor types are discussed. Most common malignant neoplasms of children are: 1. Leukemia (36.3%). 2. Tumors of central nervous system (10.7%). 3. Lymphoma, and tumors of sympathetic nervous system (19.9%). 4. Soft tissue (6.1%). 5. Kidney (7.6%). 6. Bone (4.6%). Most of the male excess (1.9:1, p less than 0.01) is accounted for by acute lymphocytic leukemia, and central nervous system tumors. It is evident that about one-half of all children diagnosed currently with a malignant disease will survive for a long period. Psychosocial aspects of cancer in the young are commented. This paper examines how patients, family members and medical staff feel and behave in response to occurrence of cancer in adolescent.

[Epidemiologic aspects of visceral leishmaniasis in the Province of Granada].

Authors make a retrospective study in 18 children with kala-azar, considering in every case the following epidemiological aspects: age, sex, situation, time of the year and lethality. They have also studied the vector of this disease in some points in Granada and after an adequate study concluded that the main vector of the kala-azar in the investigated zone is "Phlebotomus perniciosus". They have detected as well a new species in Spain, "Plebotomus longicuspis", with a slight epidemiological interest. Finally both investigations are compared finding two zones in Granada (the town and the coast) where most of the cases of kala-azar, are agglutinated and where main species of the vectors were found.
