PREVALENCE OF ENDEMIC GOITRE IN SCHOOL CHILDREN: SHIRUR (DIST. PUNE,MAHARASHTRA)

A survey for estimation of goitre in school children in the Rural Health Training Centre, Shirur area was undertaken. A total of 4664 students from 17 schools were surveyed. The goitre prevalence was found to be 59.8% with visible goitre rate of 6.2% in pre- and peri-adolescent (10–19 years) age group. Thus a highly endemic goitre focus was located in Shirur, area in Pune District (Maharashtra). This area is located on the eastern tail-end slopes of Sahyadri Hills in Balaghat ranges, situated at an altitude of 533 metres. The area is generally drought prone and receives scanty rain, with poor agricultural practices. Environmental deficiency of iodine was found to be the main cause for this high prevalence of goitre.KEY WORDS: Goitre endemic, Iodine     

Gastro-enteritis outbreak among Nordic patients with psoriasis in a health centre in Gran Canaria, Spain: a cohort study

Background

Between November 2 and 10, 2002 several patients with psoriasis and personnel staying in the health centre in Gran Canaria, Spain fell ill with diarrhoea, vomiting or both. Patient original came from Norway, Sweden and Finland. The patient group was scheduled to stay until 8 November. A new group of patients were due to arrive from 7 November.

Methods

A retrospective cohort study was conducted to assess the extent of the outbreak, to identify the source and mode of transmission and to prevent similar problems in the following group.

Results

Altogether 41% (48/116) of persons staying at the centre fell ill. Norovirus infection was suspected based on clinical presentations and the fact that no bacteria were identified. Kaplan criteria were met. Five persons in this outbreak were hospitalised and the mean duration of diarrhoea was 3 days. The consequences of the illness were more severe compared to many other norovirus outbreaks, possibly because many of the cases suffered from chronic diseases and were treated with drugs reported to affect the immunity (methotrexate or steroids). During the two first days of the outbreak, the attack rate was higher in residents who had consumed dried fruit (adjusted RR = 3.1; 95% CI: 1.4–7.1) and strawberry jam (adjusted RR = 1.9; 95% CI: 0.9–4.1) than those who did not. In the following days, no association was found. The investigation suggests two modes of transmission: a common source for those who fell ill during the two first days of the outbreak and thereafter mainly person to person transmission. This is supported by a lower risk associated with the two food items at the end of the outbreak.

Conclusions

We believe that the food items were contaminated by foodhandlers who reported sick before the outbreak started. Control measures were successfully implemented; food buffets were banned, strict hygiene measures were implemented and sick personnel stayed at home >48 hours after last symptoms.

Predicting hemolytic disease of the newborn: a comparison of the monocyte monolayer assay and the chemiluminescence test

The ability of the monocyte monolayer assay (MMA) and the chemiluminescence test (CLT) to predict the clinical significance of alloantibodies associated with hemolytic disease of the newborn (HDN) was assessed by the use of 22 well-characterized antisera– predominantly anti-D–from alloimmunized pregnant women. Seventeen sera were obtained before delivery from women whose infants were antigen positive for the antibody specificities identified in the maternal serum. With testing of these 17 sera by MMA, 10 results were in agreement with the presence or absence of HDN, but there were 5 false- positive and 2 false-negative results. With the CLT, 16 results were in agreement with the presence or absence of HDN, and there was 1 false- negative result. Five sera were obtained from women whose infants were antigen negative for the antibody specificities identified in the maternal serum. The CLT and the MMA were both subject to false-positive results with these sera. These results suggest that the CLT may be more valuable than the MMA as a noninvasive test for predicting the clinical significance of alloantibodies in HDN.     

Traumatische Aortenverletzungen bei polytraumatisierten Patienten

Herein we report our results of treatment of traumatic aortic ruptures in severely injured patients with either open surgery or endovascular stent graft repair.Data were analyzed retrospectively from the trauma registry of the DGU (Deutsche Gesellschaft fur Unfallchirurgie) over a time period from 1993 through 2002. All patients with traumatic rupture of the aorta were included and analyzed for injury severity (ISS), blood pressure (mmHg), hemoglobin (mg/%), and AIS (Abbreviated Injury Score) of the thoracic, abdominal, and upper extremity regions. Patients treated between 1998 and 2002 were further examined (operation within 24 h, duration of intervention, blood transfusion, and lethality with regard to either open surgical or endoluminal stent graft repair).Of 14,110 patients, 100 (0.7%) suffered from acute aortic rupture. Mean age was 38 years (+/-19) with an inhospital lethality of 39% (n=39). Mean ISS was 41 (+/-14); 36 patients were treated by open surgery and 5 patients by a stent-assisted endoluminal procedure. Lethality was 17% for open surgery and 0% for stent graft repair.Endovascular approach to traumatic rupture of the aorta is feasible and safe. It has been shown to reduce inhospital lethality and may offer an alternative to open surgery for severely injured patients.
