[Diseases transmitted through water for human consumption].

The water for human consumption maintains a biological risk and can transmit diseases. The classical waterborne and the presently frequent diseases caused by protozoi Giardia and Cryptosporidium are considered and Arcobacter butzleri, a new waterborne pathogen, is described. Many measures have been adopted by institutions to ensure the quality of the drinking water. Managers and public health operators is working in order to verify the efficiency of more suitable indicators for its monitoring.

Risk factors for psoriasis: a retrospective study on 501 outpatients clinical records.

Possible risk factors for psoriasis were studied by means of a retrospective evaluation of epidemiological and clinical features in 472 clinical records of outpatients affected by plaques psoriasis. We calculated the relation between the categorical variables with chi-squares contingency table analysis (with Yates correction) and odds ratio (O.R.) from the two variables with their respective confidence intervals at 95%. Among patients 267 were men (57%) and 205 women (43%); the mean age was 46.5+/-16.7 years, with no differences in sex. A significant relationship was found between age at onset < or =40 years and familiarity for psoriasis (p<0.0001-O.R.=2.71, C.I..95%: 2.12-3.48). The percentage of men with extensive lesions (extension >30%) was significantly higher than of women (p<0.05-O.R.=1.60, C.I..95%:1.35-1.90). Moreover, a significant association between extension of lesions and BMI was detected (p<0.0107-O.R.=2.10, C.I.95%:1.33-3.30) and the strength of this relation was assessed using the linear regression test. Mean age at onset was significantly lower in patients systemically treated (p<0.0003-O.R.=2.61, C.I.95%: 1.69-4.04). The results obtained can provide the basis for a standard clinical record, including data for a prospective study that may confirm the relation between psoriasis and some risk factors.

[Iron nutrition in Mapuche infants fed with human milk (2d phase)].

Blood hemoglobin, serum iron, total iron binding capacity (TIBC) and serum ferritin were measured in 140 healthy rural mapuche (southern Chile's indigenous ethnic group) infants aged 8 to 15 months: 90 had been exclusively breast fed for the first 5 or 6 months of life, then solid foods were introduced but cow's milk was never given to them. The remaining 50, which were all weaned at nearly 4 months of age and then given cow's milk and solid foods at the corresponding age, were designated as controls. Anemia was detected in 4.5% of breast fed infants and in 38% of controls. Evidence of iron deficient erythropoiesis was found in 5% and 81% of cases and controls, respectively. Human milk apparently protects this ethnic group from iron deficiency anemia and this protection seems to be better in mapuche infants than in other groups of chilean infants, because these late have shown 30% incidence of anemia around the first year of life in other studies. More studies on differences in iron nutritional state among mapuche and non mapuche are needed and are under way.

[Oculogenital infections caused by Chlamydia trachomatis].

C. trachomatis, the causative agent of hyperendemic trachoma and lymphogranuloma venereum, is also responsible of sexually transmitted infections. It is now recognized that genital chlamydial infections are the major cause of sexually transmitted diseases in Western industrialized countries, surpassing the importance of gonococcal infections. C. trachomatis, obligate intracellular parasite, enters the epithelial cells of genital mucosae and can reach, luminally, other organs of both female and male genital tract originating different clinical pictures. Vertical transmission of the microorganism from the infected mother to the newborn is of great importance. The infection takes place during delivery and can lead to disease in the newborn such as inclusion conjunctivitis and interstitial pneumonia. The present review deals mainly with clinical features and the most frequent complications of chlamydial infections. The identification of subjects at risk and the improvement of diagnostic techniques is of utmost importance since a prompt antibiotic treatment can eradicate the microorganism at least in uncomplicated infections, preventing the sequelae of the disease.

[Adrenal masses discovered incidentally].

The introduction of new diagnosis techniques has made the study of the suprarenal gland much more accessible. In particular, ultrasonography, CAT and MRI have contributed to the increased detection of suprarenal masses by chance, and this raises problems when it comes to deciding the attitude to take to the diagnosis of these masses. We present nine suprarenal tumours, most of which appeared in the course of follow-up of patients suffering from carcinoma of the bladder. On detecting a suprarenal mass, we carry out a morphological study with CAT as well as determination of hormonal activity and puncture with cytology of the mass, according to the schema proposed by Copeland. We comment on the most significant clinical aspects and on the criteria of action proposed by various authors.

Dental disease, caries related microflora and salivary IgA of children with severe congenital cardiac disease: an epidemiological and oral microbial survey.

The objectives were to determine levels of dental caries, plaque accumulation, gingival inflammation, knowledge of dental health practices, and oral bacterial loading of S. mutans, Lactobacillus sp., Candida sp., and salivary IgA in the mouths of children afflicted with severe congenital heart disease. A total of 60 children from the cardiac units of the Hospital for Sick Children and Guys Hospital Paediatric Department were compared with 60 case-matched control children from the Department of Orthodontics and Paediatric Dentistry, UMDS (Guys Dental School), London. Using the methodology of the World Health Organization, the decayed, missing and filled surfaces and teeth of primary (dmft) and permanent (DMFT) were compared. There were similar levels of caries in the cardiac (dmft 3.9 and DMFT 2.7) and the control (dmft 3.7 and DMFT 2.0). A significant difference was the proportion of untreated carious lesions in the cardiac group (52%) compared to the control group (32%; P < 0.001). Standard oral microbiological techniques were used to isolate S. mutans, Lactobacillus sp., Candida sp., and conventional methods for estimating salivary IgA. There was no difference between the cardiac and the control group. Children with severe congenital cardiac disease have moderately high levels of dental caries with a significantly greater amount of untreated disease. The high bacterial loading associated with high levels of bacterial dental plaque and gingivitis may put cardiac patients at unnecessary risk of developing bacterial endocarditis.
