INTRODUCION: Cardiovascular disease has the potential to lead to sudden in-flight incapacitation and permanent grounding. The aims of this study are to examine the relationships between lifestyle, job stress and blood lipid levels of male aircrew personnel of a Korean airline and to identify which factors influence their hyperlipidemia. METHODS: Two hundred sixteen male aircrew personnel completed a questionnaire by self-report and consented to participate in the study. The questionnaire collected data related to job stress, life style, serum cholesterol levels and general characteristics of the aircrew. The cholesterol levels of the subjects were collected from their most recent health check-up records. Subjects were divided into two groups (the desirable group and the risk group) based on their serum cholesterol level, 200 mg/dl. RESULTS: Mean age and marital status were significantly different between the two groups. More subjects in the risk group had habits of eating high lipid foods, while more subjects in the desirable group exercised more frequently than the risk group. In logistic regression analysis, after controlling age and marital status, types of working situation (domestic duty or international duty, odds ratio=.390, p=.018), diet (odds ratio=.429, p=.037), and exercise (odds ratio=.320, p=.055) were influencing factors on aircrew's serum cholesterol levels. CONCLUSIONS: The cholesterol level of aircrew personnel is closely related to their lifestyle, such as lipid diet and exercise. The type of work situations, e.g. staying in an airplane for long periods of time or staying abroad, may influence these diet patterns and exercise habits.

Anti-glomerular basement membrane antibody mediated rapidly progressive glomerulonephritis is a rare autoimmune disease. It is characterized by acuterenal failure and crescentic glomeruli with linear immune deposits along glomerular basement membrane mediated by anti-GBM antibodies. We report a case of a sixty-years-old man with generalized edema and hematuria. On admission, BUN/Creatinine was 118/19.6 mg/dL, Hb was 10.2 g/dL. On urinalysis, protein was 3+, and many RBCs were found. Renal biopsy specimen which contained 8 glomeruli showed active cellular crescent formation in all glomeruli. On immunofluorescent staining specimen, there were 4 glomeruli which showed strong IgG linear staining along the glomerular basement membrane and mild C3 & C1q deposit along the capillary walls. The titer of anti-GBM antibody was 123 EU by ELISA (normal: <10 EU). We treated with high dose of corticosteroid and plasmapheresis, but renal function was not recovered even after 3 months of hemodialysis.

Typhoid fever often manifests hepatic involvement but pleural involvement has rarely been reported to occur as a complication of typhoid fever. One case of typhoid pleurisy, in which Salmonella was isolated from the blood, is presented with the brief review of the literature. A 44 year old female was admitted to the hospital because of high fever, abdominal pain. Typhoid fever was diagnosed by blood culture, Widal test, and liver function test. Chest X-ray and pleural effusion examination demonstrated pleurisy. With the administration of ceftriaxone and pleural aspiration, she became afebrile with subsidence of pleural effusion.

The double pylorus is a fistulous communication between gastric antrum and duodenal bulb. It appears to be an acquired lesion in the majority of cases. Upon routine endoscopic procedures, it is frequently seem to occur in males who are either alcoholics, diabetics, those with chronic renal failure, chronic lung disease. If it is no developing complications such as septal rupture, double pylorus is well response to medical treatment. A 51-year-old man who had been taking medication over a long period for the chronic bronchitis was admitted to this hospital because of epigastric soreness and indigestion for 1 month. Endosopic findings showed two large openings of the pyloric channel and gastric ulcer in the channel. We thought that this case was an acquired lesion reasult of repeated gastric ulcer. We report a case of double pylrous with the brief review of literatures.

Classic distal renal tubular acidosis(type 1 RTA) is a hypokalemic, hyperchloremic metabolic acidosis due to selective defect in distal acidification. Type 1 RTA may be associated with genetic(usually autosomal dominant) or autoimmune disease, drugs and toxin and various tubulointerstitial diseases. This case report describes a 27 year-old female patient with distal RTA, Sjogren' s syndrome and Graves' disease the first case. She had been suffered from muscle weakness and peripheral numbness and was found to have low serum potassium(1.6mEq/L). She was revealed to have 1) distal RTA by NaHCO3 loading test 2) Sjogren' s syndrome by Schirmer' s test and palate biopsy and 3) Graves' disease by exophthalmometry and autoantibody test, thyroid function test. This is the first case as far as I search that report the association of distal RTA, Sjogren' s syndrome, and Graves' disease caused by autoimmune mechanism.

Objective: The aim of this study was to analyze the origins of prostatic arteries (PAs) in the Korean population and compare them with those reported in the literature. Materials and Methods: From April 2018 to February 2024, 108 male (mean age ± standard deviation: 71.6 ± 9.7 years) with lower urinary tract symptoms (n = 102) or refractory hematuria (n = 6) underwent prostatic artery embolization (PAE). Computed tomography and angiography images were retrospectively reviewed. The branching pattern of the internal iliac artery (IIA) was classified according to the Yamaki system. The origin of the PA was categorized using the de Assis definition, and the incidence of each type was recorded. A systematic literature review was conducted and the most common types of PA were investigated. Results: PAE was successfully implemented on 211 of the 216 pelvic sidewalls. PA cannulation failed in five sidewalls due to a steno-occlusive state. The most common IIA type was type A, in which the IIA was divided into the superior gluteal artery and gluteal–pudendal trunk (77%). Of 226 PAs analyzed, including 15 in 211 sidewalls exhibiting dual PAs, the most common PA origin was the internal pudendal artery (type IV, 35%), followed by the superior vesical (type I, 25%) and obturator (type III, 21%) arteries. Anterior division of IIA (type II) was less common (10%). Type V (uncommon origins) occurred in 8% of cases, including five distal internal pudendal arteries, four quadfurcations, three inferior gluteal arteries, three trifurcations, two medial femoral circumflex arteries, and two rectal arteries. Two of the five patients with surgically or endovascularly altered anatomy were successfully treated via PAs originating from the medial femoral circumflex arteries. Globally, type I is the most common PA type. Conclusion In the Korean population, the most common IIA pattern and PA origin were types A and IV, respectively.
