[Epidemiological study on diabetic patients with foot infection leading to amputation in Razee Hospital in Ahvaz during 1381-1383]

Diabetic mellitus is the most prevalent etiology for non traumatic amputations in the world that usually begin with a wound in lower extremities. About 15% of diabetic patients will have wound in their foot. According to texts there is relation between amputation and some factors like: male sex, neuropathy, vascular diseases, uncontrolled blood sugar, diabetes lasting more than 10 years and abnormal biomechanics of foot. The aim of this study was to determine the relationship between the rate of amputation of diabetic foot with some other variables of patients such as age, sex, where they live and also with specific factors of disease [like lasting time of diabetes, diabetes treatment]. This is an analytical descriptive study that performs retrospective work on the file of patients with diabetic foot infection who were admitted in Razee hospital in Ahvaz between years 1381-1383. A total of 198 patients were divided in two groups [with and without amputation] statistical analyses were employed using SPSS for windows by different tests. The results showed, that there was not an significant relationship between the rate of amputation and sex, age, site of living, last time of foot wound and foot infection [p>0.05], but there was meaningful relationship between the rate of amputation with the duration of diabetes and the treatment of the disease [p<0.05]

[Prevalence of giardiasis in daycare children at rafsanjan nurseries in 2003]

Giardia Lambelia is a unicellur parasite, and has been recognized to be the most common intestinal pathogen worldwide specially in the developing countries. The Giardia agent has been implicated as a common cause of diarrhea in children of daycare centers. Therefore, regular and continuous investigation of this infection is necessary to control and contain the epidemic of this disease particularly at the children nurseries. The present study was performed to determine the prevalence of giardiasis at Rafsanjan's nurseries in 2003. This cross sectional study was accomplished on 252 children who were selected randomly with the mean age of 5.33 +/- 0.96. All relevant variables including age, sex, type of nursery, parent's job and education, and past history of parasitic infectious disease were gathered from all the participants. Three stool samples were collected from chidren on an every other day basis. The samples were examined using direct and formalin-ether methods .The positive reports were then statistically analyzed. Of all 252 participants, at public nurseias 140 girls [55.56%] and 112 boys [44.44%], the stool exams of 44 children [17.5%] were positive for giardiasis. Twenty seven of the infected children were male. The percentage of giardiasis in children whose mothers were housewife with low education was 22.4% [19 cases]. This value among children with poor personal hygiene and with a history of parasitic infectious diseases was 44.4%, and 69.2% respectively. based on our findings, giardiasis still must be regarded as a hygienic problem especially in public nurseries and it can be prevented by continuous public education, and regular training of health workers focusing on improvement of personal hygiene
