Traumatic brain injury (TBI) is one of the leading causes of death in the pediatric population in Korea. In addition, it can cause disability in children and adolescents, with physical and mental consequences. This causes a substantial burden on the health care system and occurs globally and not just in Korea. We searched and reviewed current data on the epidemiologic characteristics of pediatric TBI in Korea. Our review provides the recent epidemiological trend mainly focusing on incidence and mortality along with worldwide reported data. This review will be helpful to understand the global epidemiology of pediatric TBI and its differences between countries.

The author reviewed 263 cases of pulmonary tuberculosis operated on at the Department of Thoracic Surgery, Seoul National University Hospital during the 19 year period, from January, 1957 to December 1975. Following observations were made: 1) The sex ratio was 2.8: 1 in male's favor, and 83.6% of the patients were between 20 and 49 years of age. 2) The trends in operative procedures revealed that surgical collapse as a definitive therapy of pulmonary tuberculosis has virtually disappeared and operations required for residuals of pleural diseases have increased. 3) The overall hospital mortality rate was 3-8%. The highest mortality rate was encountered in the cases of resection and decortication with 28.6%, 4) The rate of overall postoperative complications was 24.7%, the highest being encountered in decortication with 56.4%. 5) The most frequent cause of death was bleeding, while the dead space was the most frequent complication.

Between 1983 and 1993, 250 patients over 16 years of age who had undergone a surgical correction of a congenital cardiovascular disease were reviewed. 222 patients were divided into acyanotic group and 28 patients were cyanotic group. The most common defects were atrial septal defect [96 patients and ventricular septal defect [95 patients . There were 128 patients in the third decade, 71 patients under 20 years of age, 40 patients in the fourth decade and 11 patients over 40 years of age. The male to female ratio was 1.05:1. Operative mortality was 6.8% [4.1% in the acyanotic group and 26.8% in the cyanotic group and the most common cause of death was low cardiac output syndrome.

Background: Lung cancer is the most frequent cancer in males and the fourth most frequent site in females, worldwide. This study is the first to explore the profile of lung cancer in Kuwait. Materials and Methods: Cases of primary lung cancer (Kuwaiti) in Kuwait cancer Registry (KCR) were grouped in 4 periods (10 years each) from 1970-2009. Epidemiological measures; age standardized incidence rate (ASIR) with 95% confidence intervals (CI), Standardized rate ratio (SRR) and Cumulative risk and Forecasting to year 2020-2029 used for analysis. Results: Between years, 2000-2009 lung cancer ranked the 4th and the 9th most frequent cancer in males and females respectively. M:F ratio 1:3. Mean age at diagnosis (95%CI) was 65.2 (63.9-66.4) years. The estimated risk of developing lung cancer before the age of 75 years in males is 1.8% (1/56), and 0.6 (1/167) in females. The ASIR for male cases was 11.7, 17.1, 17.0, 14.0 cases/100,000 population in the seventies, eighties, nineties and in 2000-2009 respectively. Female ASIR was 2.3, 8.4, 5.1, 4.4 cases/100,000 population in the same duration. Lung cancer is the leading cause cancer death in males 168 (14.2%) and the fifth cause of death due to cancer in females accounting for 6.1% of all cancer deaths. The ASMR (95%CI) was 8.1 (6.6-10.0) deaths/100,000 population and 2.8 (1.3-4.3) deaths/100,000 population in males and females respectively. The estimated Mortality to incidence Ratio was 0.6. Conclusions: The incidence of lung cancer between years 2000-2009 is not different from that reported in the seventies. KCR is expecting the number of lung cancer cases to increase.

The most common cause of death is ostrich chick fading syndrome(OCFS), which is due to bacterial infection during artificial incubation and hatching. Six farmed ostrich chicks aged 3 and 10 days in Chonbuk province, were submitted to Chonbuk Livestock Development and Research Institute for necropsy, Clinically, birds showed hair loss, ocular exudate, lethargy, diarrhea, and subsequently died 3-5 days after onset of clinical signs. Grossly, umbilicus was enlarged. White-yellowish purulent nodules were scattered on the lung and the membrane of air-sac was thickened and had inflamed exudate on the surface in two chicks that died 3 days after hatching. In 10 days-old chick, intestine was shown rodding segmentally. Yolk sac was still retarded and its surface was partially hemorrahgic. The synovial fluid of the leg was yellowish. Microscopically, multifocal purulent exudates were scattered on the lung. Capillary microthrombi in the glomerulus were prominent and tubular epithelia were necrotic. Necrotic hepatocytes were scattered and intestine were congested. Microbiologically, Pseudomonas sp and/or E coli were isolated from air-sac, lung and/or liver. This case suggests that poor hygiene during artificial incubation, hatching or in the first week after hatching may cause high mortality of the ostrich chicks.

Background: For decades, trauma has been recognized globally as a major cause of death. Reducing the mortality of patients with trauma is an extremely pressing issue, particularly for those with severe trauma. An early and accurate assessment of the risk of mortality among patients with severe trauma is important for improving patient outcomes. Methods: We performed a retrospective medical record review of 582 patients with severe trauma admitted to the emergency department between July 2011 and June 2016. We analyzed the associations of in-hospital mortality with the baseline characteristics and initial biochemical markers of patients with severe trauma on admission. Results: The overall in-hospital mortality rate was 14.9%. Multivariate logistic regression analysis showed that the patient's Rapid Emergency Medicine Score (REMS; odds ratio [OR], 1.186; 95% confidence interval [CI], 1.018-1.383; p=0.029), Emergency Trauma Score (EMTRAS; OR, 2.168; 95% CI, 1.570-2.994; p<0.001), serum lactate levels (SLL; OR, 1.298; 95% CI, 1.118-1.507; p<0.001), and Injury Severity Score (ISS; OR, 1.038; 95% CI, 1.010-1.130; p=0.021) were significantly associated with in-hospital mortality. Conclusion: The REMS, EMTRAS, and SLL can easily and rapidly be used as alternatives to the injury severity score to predict in-hospital mortality for patients who present to the emergency department with severe trauma.

Total 20 cases of reoperation for mitral vavular disease, which had been performed during the period from May 1983 till October 1991, were reviewed. This study contained 1 case of previous balloon valvuloplasty and 1 case of death with bleeding from right ventricle during sternal reenrty. The average time intervals between reoperation and previous operation was 19 years in closed mitral commissurotomy[n=4], 7 years and 2 months in mitral valve replacement[n=10], 1 year and 8 months in mitral valvuloplasty[n=4], 3 years and 10 months in open mitral commissurotomy [n=2]. The cause of reoperation in closed mitral commissurotomy was progression of the disease, and residual stenosis with progression was the cause in open mitral commissurotomy cases. Technical failure might be the cause in the cases of valvuloplasty. In prosthetic valve replacement group the causes of reoperation were primary failure. Also two cases of suggested valve thrombosis and one case of failure of tricuspid annuloplasty was noted in prosthetic valve replacement group. The used valves for reoperation were Ionescue-Shiley in 3 cases, Bjork-Shiley in 6 cases, St. Jude Medical in 2 cases and CarboMedics in 8 cases. The mortality rate was 20%[n=4] and the causes of death were low output syndrome in 1 case, multiple organ failure in 2 cases and bleeding in 1 case during sternal reentry. During follow up 1 case of sudden death was observed.

Necrotizing fasciitis (NF) is an infection that spreads along the fascial planes, causing subcutaneous tissue death characterized by rapid progression, systemic toxicity, and even death. NF often appears as a red, hot, painful, and swollen wound with an ill-defined border. As the infective process continues, local pain is replaced by numbness or analgesia. As the disease process continues, the skin initially becomes pale, then mottled and purple, and finally, gangrenous. The ability of NF to move rapidly along fascial planes and cause tissue necrosis is secondary to its polymicrobial composition and the synergistic effect of the enzymes produced by the bacteria. Treatment involves securing the airway, broad-spectrum antimicrobial therapy, intensive care support, and prompt surgical debridement, repeated as needed. Reducing mortality rests on early diagnosis and prompt aggressive treatment.

During the past 3 years, 15 patients who could not be anesthetized generally because of poor general condition or cachecic state, of 111 patients with empyema, have been treated with modified Eloesser`s operation under the local anesthesia with 2% procaine. There were 13 males and 2 females ranging from 21 years to 61 years of age. The etiology was tuberculosis [6 cases], pyogenic pneumonia [5 cases], lung abscess [1 case], post-trauma [2 cases] and malignancy[1 case]. " The over-all mortality rate was 6.7%[1 case] and cause of its death was poor oral feeding because of post-traumatic psychosis. Modified Eloesser`s operation was performed after closed tube thoracostomy and irrigation with 1% zephanon solution for over 2 weeks. And then the other operation was not performed and all patients except 1 case appeared good progression (Complete healing; 4 cases, Progressive healing 10 cases, death: 1 case).

The leading cause of death in patients with chronic renal failure is cardiovascular diseases. The problems relevant to cardiac surgery in these patients are occurring more frequently with a growing number of patients at risk. Among these, important risk factors related to uremic patients undergone open heart surgery are fluid and electrolytes imbalance, coagulopathy, increased susceptibility to infection. Since 1968 when Lansing and colleagues reported the first successful aortic valve replacement in patients with chronic renal failure and infective endocarditis, there have been increasing reports of the cardiopulmonary bypass surgery in chronic renal failure patients with acceptable perioperative morbidity and mortality From Jan. 1988 to Nov. 1989 we have experienced four uremic patients necessitating open heart surgery ; one needing a coronary artery bypass graft and the other 3 needed cardiac valve replacement. Based on our observations we would like to suggest followings 1]Intraoperative ultrahemofiltration during C-P bypass thought to be an excellent means for the control of hyperkalemia and fluid balance. 2] The immediate postoperative application of peritoneal dialysis instead of hemodialysis is beneficial in controlling fluid and electrolyte imbalance. 3]The cause of one early postoperative death was not associated to renal failure, rather it was the result of an accidental rupture in the right ventricular wall.
