Most of the pneumoconiosis, which is common occupational diseases, is found here in Korea can be Gategorized to coal miner's pneumoconiosis. However, recently pneumoconiosis has been found in tHe workers of manufacturing factories, Periodic Health examination is important not only detection of occupationsl disease but also post-examination Health care of occupational disease patient. Accordingly, to study post-examination Health GaTe statHs of workers with pneumoconiosis diagnosed from 1991 to 1993 in the perioaic Health examination, all 43 pneumoconiosis patients in 22 manufacturing factories in Incheon were reviewed. Chest radiologic findings of 43 workers were suspected pneumoconiosis (20 workers, 46.5%) , pneumoconiosis stage 1(20 workers, 45.5%) and pneumoconiosis stage II (3 workers, 7.0%) . Among the 1.espondents, 40 workers (93.0%) answered that they received their health examination results and 24 werkers (55.8%) Had reguest for compensation of occupationsl disease. Only 14 workers(32.6%) Had changed their workplace while 21 workers (48.8%) did not. Reasons for not taking the post-examination health care enough were worker's ignorance of adminstrative process for Compensation (28 workers,65.1%) , mild status of dlsease (6 workers, 14.0%) and financial problem (3 workers, 7.0%) . Post~examination health care of the workers diagnosed as pneumoconiosis had significant correlation with the presence of health care manager in workplace and the employer concerns for occupational disease of workers. The improvement of working environment is related witH the presence of labor union in workplace. These results suggested that the presence of health care manager in the workplace and concerns for workers health by employer were important in performing appropriate post-examination health care for workers with pneumoconiosis in manufacturing factories.

Background: Many studies have assessed the risk factors for adverse drug reactions (ADRs) in elderly patients. However, most of these studies have focused on risk factors for ADRs, not serious ADRs (s-ADRs). s-ADRs are commonly found in hospitalized patients. s-ADRs warrant imminent but thorough investigations, given their critical impact on patient health. Therefore, this retrospective study aimed to assess the associated risk factors for s-ADRs in elderly hospitalized patients. Methods: In-patients aged >65 years having ADRs during hospitalization at a university hospital in Korea between 2010 and 2012 were included. Medical professionals spontaneously reported ADRs using an electronic submission system at the study hospital. Further, all descriptions of ADRs were characterized and categorized through the screening of electronic medical records. We compared the characteristics of patients having s-ADRs with those of patients not having s-ADRs. Results: There were 353 cases of ADRs, 67 of which were s-ADRs. Patients taking more than eight concomitant drugs showed the highest odds ratio (OR, 11.99; 95% confidence interval [CI], 3.42–42.03). The ratio of aspartate aminotransferase (AST)/alanine aminotransferase (ALT) was also significantly related to s-ADRs (OR, 2.78; 95% CI, 1.33–5.81). The use of antibiotics (OR, 2.39; 95% CI, 1.13–5.02) and antineoplastics (OR, 4.17; 95% CI, 1.09–15.94) were significant risk factors. Conclusion Our findings highlight the importance of polypharmacy. Liver function tests (AST/ALT ratio) must be monitored carefully within high-risk groups for ADRs.

We present a case of accessory tragus (AT) which developed at an unusual site, the nasal vestibule, of a 1-day-old girl. To our knowledge, this is the first report of an accessory tragus that appears on the nasal vestibule.

PURPOSE: Leptin has been considered a link between metabolic state and reproductive activity. Defective reproductive function can occur in leptin-deficient and leptin-excessive conditions. The aim of this study was to examine the effects of centrally injected leptin on the hypothalamic KiSS-1 system in relation to gonadotropin-releasing hormone (GnRH) action in the initial stage of puberty. METHODS: Leptin (1 microg) was injected directly into the ventricle of pubertal female mice. The resultant gene expressions of hypothalamic GnRH and KiSS-1 and pituitary LH, 2 and 4 hours after injection, were compared with those of saline-injected control mice. The changes in the gene expressions after blocking the GnRH action were also analyzed. RESULTS: The basal expression levels of KiSS-1, GnRH, and LH were significantly higher in the pubertal mice than in the prepubertal mice. The 1-microg leptin dose significantly decreased the mRNA expression levels of KiSS-1, GnRH, and LH in the pubertal mice. A GnRH antagonist significantly increased the KiSS-1 and GnRH mRNA expression levels, and the additional leptin injection decreased the gene expression levels compared with those in the control group. CONCLUSION: The excess leptin might have suppressed the central reproductive axis in the pubertal mice by inhibiting the KiSS-1 expression, and this mechanism is independent of the GnRH-LH-estradiol feedback loop.

Familial cutaneous collagenoma is a rare hereditary disease that is inherited in an autosomal dominant pattern. It is characterized by early onset of multiple, skin-colored, sometimes hypopigmented cutaneous nodules, which initially show a symmetrical arrangement on the trunk, and later on the neck and upper limbs. We report on a case of a 45-year-old female who presented with multiple oval to round hypopigmented papules measuring 5~15 mm on her trunk. Histopathologically, the lesions showed an increased amount of collagen fibers and decreased, fragmented elastic fibers in the dermis. The skin lesions were diagnosed as familial cutaneous collagenoma and no treatment was administered. To the best of our knowledge, our case is the first reported case of familial cutaneous collagenoma (FCC) in the Korean literature.

We report here on a 71-year-old female who had well-demarcated erythematous patches, along with some pearly papules, on the right cheek. Histopathological examination of the lesions revealed a basaloid cell mass, which appeared to be a superficial basal cell carcinoma, and a small keratin-filled cyst that appeared to be a milium. A part of the milium was surrounded by the basaloid cells of tumor islands and milia later developed on the lesion of basal cell carcinoma. We suggest that basal cell carcinoma may be one of the causes of secondary milia.

BACKGROUND: Recent studies have shown that blood transfusions, and especially red blood cells, are associated with potential adverse outcomes. This study was designed to investigate the effects of red blood cell transfusion according to the hematocrit on the clinical outcomes after cardiac surgery. METHODS: The 433 patients who were undergoing cardiac surgery were randomized to two groups. One group was transfused red blood cells with a hematocrit of 20%, and the other group was transfused red blood cells with a hematocrit of 20~25%. The amounts of intraoperative and postoperative transfusion and various parameters of the clinical outcomes were checked. RESULTS: In the hematocrit <20% group, the amount of infused crystalloid during operation was larger than that of the hematocrit >20% group, and the postoperative hemoglobin and hematocrit were lower than that of the hematocrit >20% group. But there were no differences of the amounts of intraoperative and postoperative transfusion, the use of inotropics, the platelet count, the prothrombin time (PT), the activated partial thromboplastin time (aPTT), the levels of aspartate aminotransferase (AST), the levels of alanine aminotransferase (ALT), blood urea nitrogen (BUN), serum creatinine (Cr), brain natriuretic peptide (BNP) and creatine kinase MB (CK-MB), the extubation time and the ICU stay time between the two groups. CONCLUSION: A hematocrit lower than 20% was tolerated by the cardiac surgical patients and it was not related to the postoperative morbidity and outcomes.

Pseudoaneurysm of the abdominal wall is a possible but very rare clinical entity. It is a known complication of surgery, trauma, or arterial puncture, but it is rarely spontaneous. Even though it can usually present with a wide range of local symptoms, it can cause referred pain via spinal cord, which is cross-excited with afferent sympathetic nervous system. We report a case of right arm pain which was referred from a small abdominal pseudoaneurysm like a referred pain from gall bladder. This rare entity should be considered in the differential for pain management in case that the pain does not resolve with medication or interventional pain management.

Reactive Perforating Collagenosis (RPC) is a kind of perforating dermatosis, which shows transepidermal elimination of altered collagens. Acquired form is developed in an adult without family history, is favorably developed in scratched region due to pruritic sense. Acquired RPC has been reported to be associated with various systemic disorders, such as diabetes mellitus, liver disease, chronic renal failure, lymphoma, AIDS, hypothyroidism, hyperparathyroidism, and neurodermatitis, accompanied by itching & scratching. We report a case of acquired RPC in a patient with HCV hepatitis who was treated with interferon alpha. Skin lesions showed multiple erythematous centrally umbilicated, crusted papules of variable sizes on the extensor surfaces of both shins.

PURPOSE: Pain is the most common and influential symptom in cancer patients. Few studies concerning pain intensity in the terminally ill cancer patients have been done. This study aimed to identify factors related with more than moderate pain. METHODS: This study used secondary data of 162 terminal cancer inpatients at the palliative ward of six training hospitals in Korea. Physician-assessed pain assessment was by 10 point numeric rating scale. Substantial pain was defined more than moderate intensity by the Korean National Guideline for cancer pain. The Korean version of the MD Anderson Symptom Inventory was self-administered to assess symptoms. Survival prediction was estimated by the attending physicians at the time of admission. RESULTS: Less than six weeks of predicted survival and more than numeric rating of six for worst drowsiness in the previous 24 h were significantly related to substantial pain (P=0.012 and P=0.046, respectively). The dose of opioid analgesics was positively related to substantial pain (P=0.004). CONCLUSION: Factors positively related to substantial pain were less than six weeks of predicted survival and considerable drowsiness. Careful monitoring and active preparation for pain are required in terminal cancer patients having those factors.
