Use of a modified cluster sampling method to perform rapid needs assessment after Hurricane Andrew.

STUDY OBJECTIVE: To rapidly obtain population-based estimates of needs in the early aftermath of Hurricane Andrew in South Florida. METHODS: We used a modified cluster-sampling method (the Expanded Programme on Immunization [EPI] method) for three surveys. We selected a systematic sample of 30 quarter-mile square clusters for each survey and, beginning from a random start, interviewed members of seven consecutive occupied households in each cluster. Two surveys were of the most affected area (1990 population, 32,672) at three and ten days after the hurricane struck; one survey was of a less affected area (1990 population, 15,576) seven days after the hurricane struck. MEASUREMENTS AND MAIN RESULTS: Results were available within 24 hours of beginning each survey. Initial findings emphasized the need for restoring utilities and sanitation and helped to focus medical relief on primary care and preventive services. The second survey of the most affected area showed improvement in the availability of food, water, electricity, and sanitation (P < or = .05). There was no evidence of disease outbreaks. CONCLUSION: For the first time, the EPI method provided population-based information to guide and evaluate relief operations after a sudden-impact natural disaster. An improvement over previous approaches, the EPI method warrants further evaluation as a needs assessment tool in acute disasters.

The effect of relocation after a natural disaster.

Twenty-five women remaining in a city devastated by an earthquake were compared with 24 relocated survivors and 25 comparison women. The women were administered a structured PTSD interview, the Hamilton Depression Scale, and SCL-90-R. The women in both exposed groups showed significantly more symptoms of avoidance, arousal, and total PTSD than the comparison group. The women in the relocated city had significantly higher depression scores than the women in the earthquake city. On the SCL-90-R, relocated women were most symptomatic and comparison group women were least symptomatic. Relocation after a disaster appears to be associated more with risk for depression than with PTSD in situations where recovery is delayed following the trauma.

HLA alleles and haplotypes in the Turkish population: relatedness to Kurds, Armenians and other Mediterraneans.

Turkish and Kurdish HLA profiles are studied for the first time. The comparative study of their allele frequencies, characteristic haplotypes, genetic distances with other Mediterraneans is complemented by neighbor-joining dendrograms and correspondence analyses. Turks, Kurds, Armenians, Iranians, Jews, Lebanese and other (Eastern and Western) Mediterranean groups seem to share a common ancestry: the older "Mediterranean" substratum. No sign of the postulated Indo-European (Aryan) invasion (1200 B.C.) is detected by our genetic analysis. It is concluded that this invasion, if occurred, had a relatively few invaders in comparison to the already settled populations, i.e. Anatolian Hittite and Hurrian groups (older than 2000 B.C.). These may have given rise to present-day Kurdish, Armenian and Turkish populations.

The relationship of acculturation and gender to attitudes toward counseling in Italian and Greek American college students.

This exploratory study examined attitudes toward professional psychological services and help provider characteristics among 232 self-identified Italian and Greek American college students in 3 Northeast colleges. Regarding general attitudes toward psychological services in the Italian American sample, women had a greater recognition of personal need for help and higher confidence in the ability of mental health professionals to meet these needs than did men. With regard to preferred counselor demographic characteristics, regardless of gender, lower acculturated Italian American students had a stronger preference for seeing an ethnically similar counselor. With the Greek American sample, there was an interaction effect between acculturation level and gender on attitudes toward services. Among the higher acculturated Greek students, women were more open regarding their personal concerns than men; however, within the lower acculturated cohort, no gender differences were found. With regard to counselor characteristic variables, and similar to Italian Americans, regardless of gender, lower acculturated Greek Americans had a stronger preference for seeing an ethnically similar counselor to discuss a personal problem. Limitations and implications for further research are noted.

Deep venous thrombosis in acute spinal cord injury: a comparison of 125I fibrinogen leg scanning, impedance plethysmography and venography.

Twenty acute spinal cord injury patients were surveyed for deep venous thrombosis (DVT) by 125I fibrinogen leg scanning, impedance plethysmography (IPG), and venography. Leg scanning was a more sensitive indicator of thrombotic events than IPG or venography. IPG was a reliable indicator of accumulated thrombosis. The incidence of dvt assessed by leg scanning alone was 100 per cent. Its occurrence as determined by either of the screening techniques was found to be considerably greater than those of previous reports.

The contribution of adrenoceptor subtype(s) in the renal vasculature of diabetic spontaneously hypertensive rats.

1. Diabetes and hypertension are both associated with an increased risk of renal disease and are associated with neuropathies, which can cause defective autonomic control of major organs including the kidney. This study aimed to examine the alpha(1)-adrenoceptor subtype(s) involved in mediating adrenergically induced renal vasoconstriction in a rat model of diabetes and hypertension. 2. Male spontaneously hypertensive rats (SHR), 220-280 g, were anaesthetized with sodium pentobarbitone 7-day poststreptozotocin (55 mg x kg(-1) i.p.) treatment. The reductions in renal blood flow (RBF) induced by increasing frequencies of electrical renal nerve stimulation (RNS), close intrarenal bolus doses of noradrenaline (NA), phenylephrine (PE) or methoxamine were determined before and after administration of nitrendipine (Nit), 5-methylurapidil (5-MeU), chloroethylclonidine (CEC) and BMY 7378. 3. In the nondiabetic SHR group, mean arterial pressure (MAP) was 146+/-6 mmHg, RBF was 28.0+/-1.4 ml x min(-1) x kg(-1) and blood glucose was 112.3+/-4.7 mg x dl(-1), and in the diabetic SHR Group, MAP was 144+/-3 mmHg, RBF 26.9+/-1.3 ml(-1) min x kg(-1) and blood glucose 316.2+/-10.5 mg x dl(-1). Nit, 5-MeU and BMY 7378 blunted all the adrenergically induced renal vasoconstrictor responses in SHR and diabetic SHR by 25-35% (all P<0.05), but in diabetic rats the responses induced by RNS and NA treated with 5-MeU were not changed. By contrast, during the administration of CEC, vasoconstrictor responses to all agonists were enhanced by 20-25% (all P<0.05) in both the SHR and diabetic SHR. 4. These findings suggest that alpha(1A) and alpha(1D)-adrenoceptor subtypes contribute in mediating the adrenergically induced constriction of the renal vasculature in both the SHR and diabetic SHR. There was also an indication of a greater contribution of presynaptic adrenoceptors, that is, alpha(1B)-, and/or alpha(2)-subtypes.

[Sonographic course of systemic echinococcosis in a 10 year old girl (with cardiac, hepatic, renal and muscular involvement)].

PURPOSE: To present the predominantly ultrasonographic (initial and follow-up) imaging in a disease that is rare among the Central European paediatric population--and to evaluate the role of ultrasound for initial staging and follow-up under antihelmintic therapy. METHOD: The imaging documents as well as the clinical record of a 10-year old Armenian girl with systemic hydatid disease (cystic echinococcosis) were analysed retrospectively. RESULTS: By means of ultrasound, the complete initial systemic spread of the disease with at least 11 cysts within the liver, 1 cyst in the left kidney, 1 peri-/2 intracardiac cysts, and 1 cyst in the dorsal musculature was detected. Repeated sonographic examinations allowed the estimation of successful medical treatment by the following criteria: size reduction of all cysts with changing internal structures from an initially echo-free to an increasingly homogeneous echodense character; no developing new cysts. In addition, CT and MRI enabled a more complete demonstration of especially the intra- and pericardiac lesions (preoperatively) and the exclusion of further intracranial cysts. CONCLUSION: In paediatric hydatid disease, ultrasonography yields important information not only with regard to the initial staging, but also to the antihelmintic therapeutic effects and thus helps to determine when to discontinue medical treatment.

Restoration of the disordered glucose-fatty acid cycle in alloxan-diabetic rats by trihydroxyoctadecadienoic acids from Bryonia alba, a native Armenian medicinal plant.

We studied how administration of trihydroxyoctadecadienoic acids obtained from the roots of the native Armenian plant Bryonia alba L. (0.05 mg/kg/day for 15 days. i.m.) restores the disordered lipid metabolism of alloxan-diabetic rats. Diabetes was accompanied by an increase in total non-esterified fatty acid content of blood together with decreases in muscle and adipose tissue of total non-esterified fatty acids and triglycerides, together with marked alterations of phospholipid fatty acid distribution within the membranes from muscle, including increased short chain fatty acid and decreased arachidonate content. All these metabolic changes induced in diabetes were significantly restored by trihydroxyoctadecadienoic acid treatment towards their normal values (P < 0.005) with the exception of diminished triglyceride content of muscle which was not restored. In experiments on rat neutrophil leukocytes in vitro, it was found that the standardised preparation of Bryonia C-18 fatty acids (a mixture of four diastereoisomeric forms of the positional isomers I 12,13,16-trihydroxy-9Z,14E-octadecadienoic acid, II 12,15,16-trihydroxy-9Z,13E-octadecadienoic acid, III 9,10, 13-trihydroxy-11E,15Z-octadecadienoic acid and IV 9,12,13-trihydroxy-10E,14Z-octadecadienoic acid) had no effect on granular enzyme secretion or 5-lipoxygenase activity at 5-50 micrograms/ml, but dose-dependently reduced thromboxane B2 generation, with a corresponding increase in prostaglandin E2 release. We conclude that trihydroxyoctadecadienoic acids from B. alba can correct major metabolic abnormalities typical of severe diabetes mellitus, and that they can influence the profile of the formation of stable prostaglandins by actions downstream of prostaglandin endoperoxides.
