The investigation of the prevalence of Thyroid cancer in operated nodular Goiter patients in Kashan Naghavi Hospital from 1983-87
History and Objectives: Considering the prevalence of thyroid cancer in nodular goiter patients and the prevalence of goiter in Kashan's region specially in the mountain area and various reports about cancer in this type of patients, this investigation was conducted to determine the prevalence of thyroid cancer in nodular goiter patients operated in at Kashan Naghavi hospital during 1983 to 1987. Materials and Methods: This research was conducted by using the existing data about all the patients who were diagnosed with nodular goiter and went under surgery. The characteristics of the patients such as age, sex, duration of having goiter, kind of goiter, types of surgery and pathological diagnosis were extracted from the patients, files and were recorded of analysis. Results: From total of 130 patients identified with nodular goiter and surgery operation, 12 patients (9.2) had cancer. The prevalence of thyroid cancer for women was five times more than men. The types of cancer included 91.7 papillar and 8.3 follicular type, consecutively. Conclusion: Considering the noticeable prevalence of thyroid cancer among the nodular goiter, proper diagnosis and prompt treatment this disease plays an important role in survival and life condition of the patients. In addition, FNA is definitely recommended and in cases that there is certainly or even suspicion about cancer, surgery must be performed. Decrement of a cold single nodule treated by thyroxin necessarily is no indication of absence of cancer. In addition, since papillar type cancer has various cystic form, consequently not all thyroid cysts are always benign. All the cysts that recur immediately after FNA even with the negative cytology report and also any nodule with the negative FNA, which is clinically suspect, must undergo surgery
Arterial Oxygen saturation (SPO2) during bronchoscopy among patients referred to Tabriz Immam Khomaini Hospital, 1994
History and Objectives: Since arterial Oxygen saturation variations during diagnostic and therapeutic procedures, i.e. bronchoscopy and reported discrepancies on the prevalence of such condition and in order to determine the arterial Oxygen saturation (SPo2) during the passage of the bronchoscope through different part of the respiratory tract, the present investigation was undertaken on individuals referred to the out-patient clinic or hospitalized at the Imam Khomeini hospital of Tabriz (1994). Materials and Methods: A descriptive study was conducted on 200 bronchoscopy candidates. Information pertaining to the personal data age, sex, major complaint, type of cardiac complication was recorded. At various stages of bronchoscopy (Before and after Oxygen administration, during Xylocaine treatment of the vocal cords, passage of the bronchoscope from the main body of the right and left bronchus, during washing and biopsy of the bronchus, during coughing and at the end of coughing), reduction of Oxygen saturation (More than 5) was taken as the fall of the arterial Oxygen saturation. Results: From 200 cases studied, 79 patients (39.5) displayed fall of SPo2. 31 patients (15.5) showed a fall of more than 10. Total of 165 SPo2 falls were recorded during various stages of bronchoscopy. Falls were especially significant during later stages of bronchoscopy and during the washing stage, the passage of the bronchoscope through the main body of right principle bronchus and during biopsy. Correlation between atelectasis and fall of SPo2 was 0.24 and between cigarette smoking and fall of SPo2 was 17 and between occurrence of arrhythmia and fall of SPo2 was 0.25. Conclusion: Since the fall of SPo2 is quite frequent during bronchoscopy, administration of the Oxygen before bronchoscopy and monitoring of the arterial Oxygen saturation by pulse oximeter during bronchoscopy is highly recommended. Further analytical investigation to the role of atelectasis and cigarette smoking on the fall of SPo2 is recommended and more experimental analysis in this subject is recommended
Study of nest architecture of scorpion Adentobotus Doria in Esfahan province, 1991
History and Objectives: Adentobotus doria has venomous and painful sting. In order to catch scorpion A.doria for clinical studies, understanding the architecture of their nest and their characteristics is essential therefore the present investigation was carried out in Isfahan province in 1991. Materials and Methods: Based on three specific characteristics the shape of entrance of the nest, (Oval shape with upper semicircle), cone shaped embarkments and the dimensions of the nest entrance (15 by 7) a descriptive study was carried out. Once nests with above characteristics were found, it is considered as the nest of A.doria. The nest was destroyed and the scorpions were caught and their taxonomy were assigned. Architecture of the nests (Length, depth, slope and shape of canals) were recorded. Results: From all 96 nests studied, A.doria was found in all the nests (100). Conclusion: From the present data, it is practical to identify and catch scorpions from the architecture of the nests
Prevalence of intestinal parasitic infections in desert and mountain regions of Kashan, 1989-90
History and Objectives: Due to the great influence of intestinal parasites on personal and social health, its variable prevalence in different parts of Iran and lack of information regarding its status in Kashan, the present study was conducted in 1989-90 to determine the prevalence of intestinal parasites in villages of the desert and mountain regions of Kashan. Materials and Methods: In this descriptive study, 2399 individuals aged 0-50 years were randomly selected in 12 mountain villages and 8 desert villages. In each case, personal information was recorded in a data sheet and 3 morning stool samples were obtained in three-day intervals and studied using the formalin ether technique. The 95 confidence interval (CI) was estimated in all regions studied. Results: The prevalence of pathogenic intestinal parasites was 37.6 (CI=34.9-40.3) in desert regions and 41 (CI=38.2-43.8) in mountain regions. Intestinal protozoa had 43.2 prevalence in rural areas of Kashan, with a 27.9 prevalence of pathogenic protozoa in desert regions and 23.9 in mountain regions. Prevalence of intestinal helminthes was 17.3 in rural areas of Kashan. Conclusion: Due to the relatively high prevalence of intestinal parasites in mountain regions, we suggest further studies to determine the causes and necessary measures to alleviate this problem and find methods to treat those infected
Seroepidemiology of Toxoplasmosis in Kashan, 1993
History and Objectives: The prevalence of the toxoplasmosis in Iran is varied. Due to morbidity of toxoplasmosis the distribution of the diseases was investigated in urban as well as rural regions of Kashan in 1993. Materials and Methods: A descriptive study covering 14 rural and 5 urban health centers including 2080 individuals (Age 2-70) was conducted. In accordance with the population of rural and urban regions random samples were taken. A questionnaire was filled and 5mL venous blood sample was collected from every individuals. In additions of 1/20 and 1/100 the presence of antibody was assessed by IFA. Positive samples for titers of greater than 1/100 were tested further for higher dilution. 1/20 dilution was taken the basis infection and 1/400 titer was significant. Confidence interval for the prevalence of the disease was taken with 95 probability. Results: Incidence of the toxoplasmosis was 50.8 in studied regions (CI=48.7±53). The prevalence for the urban regions was 47.6 (CI=44.8±50.4) and rural areas was 55.2 (CI=52.0±58.4). Antibody titer for 264 (12.7) was higher than 1/400. the rate of infection were proportional with the age of the individuals. Conclusion: This study pointed to the fact that the prevalence of the disease was high in the regions investigated. Therefore urgent attention ought to be paid to the spread of the disease and especially to individuals of higher age. It is suggested that further research should be conducted into the prevalence of the disease and the source of disease transmission and at risk individuals
