The present report deals with the behaviour of mast cells in mice in the course of Entamoeba histolytica infection by the strains. Mice weighing about l6 gm were used for three experimental groups; control, sham infection and experimental. The experimental group was infected with Entamoeba histolytica trophozoites directly into cecum by laparotomy. Strains isolated from three hepatic amoebic abscess cases were used. Mesenteric samples from the region of terminal ileum were fixed in methyl alcohol and stained with Pugh's solution. The ulcers in cecum were examined. Changes in number and structure of mesenteric mast cells and blood eosinophils were as follows. The number of mast cell in mesenteric tissues of the infected group increased from first day of the infection and persisted up to 34th day of the observation period. Degranulation and disruption of mast cells increased in the infected group compared with groups of the sham operation and the contro1, but showed no difference by the strains of Entamoeba histolytica. The blood eosinophilia was observed in the infected group and persisted until the observation period. Ulcers in cecum were found in all the infected groups. The results above indicate that mast cells are keenly related with the course of Entamoeba histolytica infection.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

The ovarian hyperstimulation syndrome is a rare but serious complication of ovulation induction therapy with gonadotropin. The clinical manifestations are generalized edema, ascites with pleural effusion and may become life-threatening in severe cases. The pathophysiology is still unknown therefore, the treatment should be symptomatic and conservative. We report a case of severe OHSS with massive right pleural effusion in excess of ten liters after human menopausal gonadotropin therapy because of secondary infertility. Fluid and electrolyte imbalances were corrected and albumin was administered. A right chest tube was placed for a total of sixteen days, draining eleven liters of pleural effusion totally, resulting a dramatic decrease of pleural effusion and improvement of symptoms.

Many radiopharmaceuticals have been developed and wildy used in the imaging cardiac function. Myocardial perfusion imaging (MPI) is a well established noninvasive method of assessing coronary blood flow and has been widely used in patients diagnosed or suspected with coronary artery diseases. The innovation of radiopharmaceuticals used in the cardiac imaging is one of the most important contributors to the development of nuclear cardiology. Thallium-201 and various technetium-99m agents have been globally used for myocardial perfusion SPECT, and N-13 ammonia (13NH3), rubidium-82 (82Rb), O-15 water (H215O) for myocardial perfusion PET. As well as the cardiac perfusion studies, new radiopharmaceuticals that visualize fat metabolism or receptors of the sympathetic nervous system have successfully been applied to clinical practice. Useful information can be obtained for diagnosing coronary artery disease, evaluating patients' condition, or assessing therapeutic effects. In this review, we describe the characteristics and clinical usefulness of radiopharmaceuticals used for cardiac SPECT and PET.

OBJECTIVE: We analyzed the degree of behavioral and psychic masculinization as well as factors influencing the masculinization in female patients with CAH caused by 21-hydroxylase deficiency. METHODS: We studied 26 patients with salt-wasting (SW) type, 29 patients with simple virilizing (SV) type and 30 control patients, who were older than 10 years of age. Study participants were given a questionnaire containing 55 items (20 masculine items, 20 feminine items, 15 neutral items) in order to evaluate the degree of feminity and masculinity. RESULTS: SW and SV girls revealed significantly higher masculine scores and lower feminine scores than the control groups (P<0.05). Feminine scores were lower in the SW group compared to those in the SV group (P<0.05). Neutral scores showed no significant difference among three groups. Masculine, feminine, bisexual and undifferentiated personality characteristics exhibit 57.6%, 3.8%, 7.6%, and 30.7% in SW group, respectively; 31%, 17.2%, 20.6%, and 30%, respectively in SV group; 3.3%, 50.0%, 20.0% and 26.6%, respectively in control group. Masculine scores were negatively correlated with age at diagnosis and treatment (r=-0.516, P<0.05), but not with the levels of 17-hydroxyprogesterone at the time of diagnosis and study, advancement of bone age, age at clitoplasty, age at onset of puberty and age at menarche. CONCLUSIONS: Female patients with 21-hydroxylase deficiency, who reveal high masculinizing score, should be closely monitored for the adverse effects of high degree of masculinization, such as polycystic ovarian syndrome. Additionally, it is important to treat adequately after early diagnosis to minimize the degree of masculinization and to develop the prenatal mode of treatment to interrupt the secretion of adrenal androgen.

OBJECTIVES: This study aimed to explore the barriers to and factors facilitating the operation of patient safety incident reporting systems. METHODS: A qualitative study that used a methodological triangulation method was conducted. Participants were those who were involved in or responsible for managing incident reporting at hospitals, and they were recruited via a snowballing sampling method. Data were collected via interviews or emails from 42 nurses at 42 general hospitals. A qualitative content analysis was performed to derive the major themes related to barriers to and factors facilitating incident reporting. RESULTS: Participants suggested 96 barriers to incident reporting in their hospitals at the organizational and individual levels. Low reporting rates, especially for near misses, were the most commonly reported issue, followed by poorly designed incident reporting systems and a lack of adequate patient safety leadership by mid-level managers. To resolve and overcome these barriers, 104 recommendations were suggested. The high-priority recommendations included introducing reward systems; improving incident reporting systems, by for instance implementing a variety of reporting channels and ensuring reporter anonymity; and creating a strong safety culture. CONCLUSIONS: The barriers to and factors facilitating incident reporting include various organizational and individual factors. As an important way to address these challenging issues and to improve the incident reporting systems in hospitals, we suggest several feasible methods of doing so.
