This article is a retrospective study on 37 patients with Crohn's disease, who have been admitted at Taleghani and Day general hospital during the past 14 years. This chronic inflammatory disease of gastrointestinal tract which is common in western world, had been rare in eastern countries including Iran until 30 years ago. The object of this study is to show the increasing incidence of Crohn's disease in Iran during the past decades. Despite some similarities, we have found differences in our patients including sex distribution and gut involvement pattern. According to the writers point of view this differences are due to the small number of evaluated patients in this study. Increased incidence of Crohn's disease in Iran is probably due to life style and diet modification, which are secondary to industrialization of the society.

The study area is located about 60 Km north-west of Shiraz, the capital city of Fars province. The mean annual precipitation and temperature are about 367 mm and 17°C, respectively. The climate is semiarid and the soil moisture and temperature regimes are xeric and thermic, respectively.The main objectives of this study were: 1- To study the morphological characteristics and pedogenic development of the calcareous soils formed on different physiographic units, and 2- To determine the mineralogical composition of these soils.In this research, the effects of topography on morphological, physical, chemical and mineralogical characteristics of calcareous soils of Beyza area were studied. Five physiographic units were distinguished, namely, alluvio-colluvial fan, piedmont alluvial plain, flood plain, river alluvial plain, and depression. Entisols, Inceptions, and Aridisols are the dominant soils in the area. The results showed that topography plays an important role in the development of the soils. The soils formed on high-lying land show little or no pedogenic development, while those developed on iow-lying areas have more horizon differentiation and pedogenic development. Soil texture, salinity and lime accumulation were affected by topography. The heavy-textured soils with a high salt and CaCO3 content were found on low-laying areas. Mineralogical study of the soils on different physiographic units showed that the composition of the soils consists of illite, chlorite, smectite and vermiculite. However, the proportion of clay minerals differs. The soils formed on high-laying areas contain more illite and chlorite than those of the low-lying lands.

During the past 10 years (1368-1377) 13 patients (7 male, 6 female) whose ranged from 11 to 54 years (mean 29.5 years) with diagnosis of ulcerative colitis were operated at Ghaem and Omid hospitals. Perforation occurred in 5 patients due to toxic megacolon or toxic colitis so they were operated urgently.The operation carried out in these patietns was total colectomy with end ileostomy and preservation of rectum as the initial treatment with 2 postoperative deaths. At the second stage usually 6-11 months later mucosal proctectomy and construction of S pouch from ileum and ileal pouch-anal anatomists (IPAA) with protective ileostomy was done in 3 survivors. After 2 months the ileostomy was removed as a third stage. Elective surgery was performed in 8 patients due to unresponsiveness to medical therapy. Each patient underwent colectomy and standard IPAA and loop ileostomy, and at a second stage after 8 weeks the ileostomy was closed. In one patient whom ileostomy didn't perform was complicated with a pelvic abscess that drained ransperineally with good result fortunately. No operative death occurred in elective patients.Of 11 patients that have had IPAA (3 survivor of urgent operations and 8 elective series) satisfactory function of the reservoir has been achieved in 10 patients. Dysfunctional of reservoir occurred in one patient. He had to catheterize the reservoir to evacuate faeces and this was attributed to the long efferent ileal limb. In this study we analyzed factors affecting technical and functional outcome.

The study was conducted to determine the clinical and etiology of cerebral venous thrombosis in Iran. Records of all adult patients admitted with a clinical diagnosis and MRI of cerebral venous thrombosis form 1993 through 1999 in three major hospitals of Tehran, Iran were reviewed. Fifty patient (39 women, 11 men) aged 14 to 56 years were identified. Headache the most frequent and often the earliest symptom, was encountered in 82 percent and papilledema, the most frequent sign in 56 percent of cases. Infection was the cause of cerebral venous thrombosis in 26 percent of our cases. Other causes included oral contraceptive (32 percent), vasculitis (6 percent). Behcet’s discase (4 percent), postpartum state (4 percent), myeloproliferative disease (2 percent), ulcerative (2 percent), antithrombin III deficiency (2 percent) and diabetic ketoacidosis (2 percent). Oral contraceptive was recognized as the most common etiology. Infection is an important cause whereas procoagulation disorders are uncommon.

The acute febrile neutrophilic dermatosis or Sweet's syndrome is characterized by fever, neutrophilic leukocytosis, abrupt appearance of erythetmatous, painful cutaneous plaques and dense dermal infiltrate consisting of mature neutrophiles without vasculitis signs. Although it may occur in the absence of other known diseases, it is often associated with hematologic and immunologic diseases. We report a case with upper respiratory tract infection before dermatologic manifestations of Sweet's syndrome who had good therapeutic response to corticosteroid therapy.

Background: Regarding the high prevalence of Inflammatory Bowel Disease (IBD), and unawareness of the disease status in Iran, and also with respect to the controversies about the etiology, age of onset, etc; this study has been carried out on patients referred to Taleghani, Shohada- e- Tajrish, and Loghman Hakim hospitals since 1992 till 1996, to determine the status of disease.Materials and methods: In this existing data study, all the patients with established diagnosis of lBD were surveyed and personal characteristic Gshad determined.Results: 59 patients had entered our study, where Crohn's disease was reported in 4, and Ulcerative Colitis and Intermittent Colitis were reported in 48 and 7, respectively. Mean age was 42±31 years. Diarrhea and rectorrahgia were the most common symptoms. (seen in 64.5%).Conclusion: It seems as if Crohn's disease has lower prevalence in our country, meanwhile, IBD was diagnosed in elder patients here in Iran. Symptoms have shown slight differences with those described in other studies.
