Objective: High-quality cardiopulmonary resuscitation (CPR) needs to be provided to cardiac arrest victims. The chest compression at a 5-6 cm depth and 100-120 beats per minute are recommended according to the 2015 CPR guidelines. The physical forces to the patient’s chest wall cause inevitable complications. This study analyzed the CPR-related complications based on computed tomography (CT). Methods: This was a retrospective, single-center study. The study period was from 2009 to 2019. The cardiac arrest victims received the CPR in or out-of-hospital. After the return of spontaneous circulation, CTs were performed on some survivors. The complications detected on CTs were reviewed, and the types and frequencies of complications, age, sex, arrest location, CPR duration, the survival discharge were investigated. Results: Among 1,357 cardiac arrest patients during the study period, 368 patients were enrolled. The average age was 64.2, and 66.3% were male. The average CPR duration was 24.6 minutes. The most frequent complication was rib fracture (73.6%). Lung contusion (41.3%), hemothorax (22.0%), sternal fracture (19.3%), and retrosternal hemorrhage (13.6%) were also detected. Those with rib fractures, sternal fractures, and retrosternal hemorrhage were older (P<0.001). Those with rib fractures, lung contusion, hemothorax received longer CPR (P=0.032, P=0.003, and P=0.041). Low survival discharge rates were observed in patients with rib fractures, sternal fractures, and pneumothorax (P=0.002, P=0.014, and P=0.016). Conclusion The rib fracture, sternal fracture, and retrosternal hemorrhage were frequent in older patients. Those with rib fractures, lung contusion, or hemothorax received the longer CPR. The survival discharge rates were low in the rib fracture, sternal fracture, pneumothorax patients.

Relapsing polychondritis is a rare disease characterized by widespread destructive inflammatory lesions, involving cartilaginous tissue throughout the body. Commonly involved organs include the external ear, nose, joints, eyes, tracheobronchial tree, cardiovascular system and cutaneous tissues. Erythema nodosum or mesenteric panniculitis have sometimes been described in association with relapsing polychondritis, but cutaneous panniculitis is rarely reported in relapsing polychondritis. We report here a relapsing polychondritis patient who developed cutaneous panniculitis, which was resolved by corticosteroid therapy.

Malignant fibrous histiocytoma(MFH) is a high grade soft tissue sarcoma, commonly occur in the retroperitoneum, extremities, head and neck in the patient with old ages. But it is very uncommon that MFH primarily occurs in the lung, and uncommon in young ages. We experienced a young male patient with primary MFH of the lung. The patient had huge masses on both lungs which were diagnosed as MFH by thoracoscopy-guided wedge resection of mass, so we could not perform operative management. And we tried 6 cycles of chemotherapy using ifosfamide, doxorubicin, dacarbazine. After chemotherapy, masses still remained in spite of decreasing sizes.

PURPOSE: This study examined the rate of degeneration of acetabular cartilage by the bipolar head according to time, and also which clinical factors are related to the degeneration of acetabular cartilage. MATERIALS AND METHODS: Among 192 patients (226 hip joints) who received bipolar hemiarthroplasty from August 1996 to August 2002, 61 patients (65 hip joints) were enrolled in this study, who were followed up for more than 2 years and showed no signs of dislocation, infection, or functional problems. A modified form of a computer assisted vector wear analysis program was used to measure the rate of degeneration of the acetabular cartilage. The factors that appeared to affect the rate of acetabular degeneration in the two groups was evaluated. RESULTS: The average linear degenerative change in the acetabular cartilage and the volumetric degenerative change were 0.23 +/- 0.107mm/year and 114 +/- 47.2mm3/year, respectively. The result showed significant differences in activity and HHS between the 2 groups. The HHS showed a reverse relationship with the linear degeneration and volumetric degeneration, and the activity showed a correlation with the linear and volumetric degeneration. CONCLUSION: The acetabular cartilage degenerates faster as the patient' activity increases, and slower with a higher HHS. When surgeons perform hip joint arthroplasty, it is strongly recommended that the life expectancy and the level of activity should be considered when deciding between a hemiarthroplasty and total hip arthroplasty.

A primary thyroid lymphoma is rare among all types of thyroid malignancy. Usually, a thyroid lymphoma is associated with underlying chronic autoimmune thyroiditis. Recently, we experienced a primary thyroid mucosa-associated lymphoid tissue(MALT) lymphoma, with an incidental micropapillary thyroid carcinoma, but lacking evidence of autoimmune thyroiditis. A female patient visited our hospital for further evaluation of a rapidly enlarging, painless thyroid mass which had been stable for 8 years. Lymphocytic thyroiditis or a lymphoma was suspected from fine needle aspiration performed at another hospital. The thyroid function test and other routine laboratory tests were normal. The histopathological findings after a total thyroidectomy revealed a MALT lymphoma with a micropapillary thyroid carcinoma. There was no evidence of chronic autoimmune thyroiditis. This is, to the best of our knowledge, the first case report of a MALT lymphoma arising from the thyroid gland without evidence of chronic autoimmune thyroiditis in Korea

Fifteen percent of patients with Cushing's syndrome could be accompanied with nonpituitary tumors that secrets ACTH-the ectopic ACTH syndrome. Among them, bronchial carcinoid is one of the rare causes of the ectopic ACTH syndrome. We experienced a 60-year-old woman who showed conditions of weight gain, generalized edema, hypokalemia, diabetes mellitus, and right middle lung mass. Histologically, the tumor was diagnosed with bronchial carcinoid and was confirmed as an ectopic ACTH syndrome through immunohistochemical staining of ACTH. After resection of the lung mass, blood sugar, electrolytes, generalized weakness, and blood pressure improved.

Thrombotic thrombocytopenic purpura (TTP) rarely may be seen in association with autoimmune processes such as scleroderma, rheumatoid arthritis, polyarteritis nodosa, Sj gren's syndrome, and systemic lupus erythematosusus (SLE). The diagnosis of TTP as a syndrome distinct from SLE may be challenging, because both processes may present with some or all elements of the classic pentad considered pathognomonic of the former: microangiopathic hemolytic anemia, fever, thrombocytopenia, neurological deficits, and renal abnormalities. We describe a patient with synchronous TTP and SLE, and review the literature.

Background/Aims: Young Korean men are obligated to serve in the military for 18 to 21 months. We investigated the effects of military service on steatotic liver disease (SLD) and other metabolic parameters. Methods: Pre-enlistment health check-up performed from 2019 to 2022 and in-service health check-up performed from 2020 to 2022 were merged as paired data. SLD was defined as a hepatic steatosis index of 36 or higher. Hypertension (HTN) and hypertriglyceridemia were also included in the analysis. Results: A total of 503,136 paired cases were included in the analysis. Comparing pre-enlistment and in-service health check-ups, the prevalence of SLD (22.2% vs 17.6%, p<0.001), HTN (7.6% vs 4.3%, p<0.001), and hypertriglyceridemia (8.1% vs 2.9%, p<0.001) decreased during military service. In terms of body mass index, the proportion of underweight (8.2% vs 1.4%, p<0.001) and severely obese (6.1% vs 4.9%, p<0.001) individuals decreased over time. Regarding fac-tors associated with SLD development and resolution, age was positively associated with SLD development (odds ratio, 1.146; p<0.001) and a health check-up interval of <450 days was a protective factor for SLD development (odds ratio, 0.746; p<0.001). Those serving in the marines were less likely to develop SLD, whereas those serving in the navy were more likely to develop SLD. Serving in the army or the navy was negatively associated with SLD resolution, whereas serving in the air force was positively associated with SLD resolution. Conclusions The prevalence of SLD, HTN, and hypertriglyceridemia decreased substantially during Korean military service.
