Intraosseous pneumatocyst is a benign, gas-filled, cystic lesion, and is commonly encountered in iliac bone or sacrum. Other locations of this lesion following trauma are rare, and only a handful of isolated cases have been reported. The pathogenesis and etiologies of this uncommon entity are various and it can present a diagnostic challenge. Only four previous cases have described the natural course of intravertebral pneumatocysts. Here, the authors report a rare case of traumatic pneumatocyst, which resolved rapidly without further complication. Possible pathogenic mechanisms are discussed and reviews of literatures are included.

OBJECTIVE: To determine the age-related changes in cardiac rehabilitation (CR) outcomes, which includes hemodynamic and metabolic factors, in patients with myocardial infarction (MI). METHODS: CR was administered for 8 weeks to 32 men (mean age, 54.0±8.8 years) who underwent percutaneous coronary intervention for acute MI between July 2012 and January 2016. The exercise tolerance tests were performed before and after the CR. The results were stratified based on a cut-off age of 55 years. RESULTS: In the whole patient group, the hemodynamic variables such as the resting heart rate (HRrest), systolic blood pressure (SBPrest), submaximal HR (HRsubmax), SBP (SBPsubmax), and rate pressure product (RPPsubmax) significantly decreased and the maximal HR (HRmax) and RPP (RPPmax) significantly increased. All metabolic variables displayed significant improvement, to include maximal oxygen consumption (VO2max) and ventilation (VEmax), anaerobic threshold (AT), and the maximal oxygen pulse (O2pulsemax). However, upon stratification by age, those who were younger than 55 years of age exhibited significant changes only in the HRrest and RPPsubmax and those aged 55 years old or greater displayed significant changes in all hemodynamic variables except diastolic BP. Both groups displayed significant increases in the VO2max, VEmax, and AT; the older group also exhibited a significant increase in O2pulsemax. The magnitude of the changes in the hemodynamic and metabolic variables before and after CR, based on age, did not differ between the groups; although, it tended to be greater among the older participants of this study's sample. CONCLUSION: Because the older participants tended to show greater hemodynamic and metabolic changes due to CR, a more aggressive CR program must be administered to elderly patients with MI.

Thirty - five cases of coarctation of aorta, diagnosed by cardiac catheterization and angiography during the period of 1980-1984, at the department of Pediatrics of Seoul National University Hospital, were studied on the clinical features and management. The followoing results were obtained : 1) The incidence of coartation of aorta was 1.2% of congenital heart disease and sex ratio of male to female was 2.2 : 1. 2) The anatomical type of coarctation was preductal in 19 cases, juxtaductal in 15 cases and postductal in 1 case. Most of preductal coarctation (89.5%) were associated with aortic arch or isthmus hypoplasia. 3) All of these patients had various type of additional cardiac anomalies and among them, PDA was the most common associated lesion and followed by VSD. 4) Significant BP gradient between upper and lower extremies and weak femoral pulsation were noticed in 15 cases(42.8%). 5) Congestive heart failure was present in all but one patient less than 1 year old, while only 3 cases(15%) had congestive heat failure in patients older than one year. 6) Overall surgical mortality was 31.8%, but significant decrease in surgical mortality was found since 1983.

Osteogenesis imperfecta (OI) is a group of genetic disorders characterized by bone fragility and connective tissue manifestations. We report a successful liver transplantation (LT) in an 8-month-old boy with OI and cholestatic biliary cirrhosis. After 4 cycles of intravenous pamidronate, LT was performed under intravenous anesthesia using a left lateral section from his mother without mechanical retractors. The operation time was 420 min and estimated blood loss was 520 mL requiring one unit of RBC transfusion. He was discharged without surgical complications. Therefore, LT should be considered for patients with end stage liver disease and OI under organic multidisciplinary cooperation.

The risk of complications associated with endoscopic procedures, including bleeding and perforation, tends to increase due to the magnification of the therapeutic endoscopic spectrum. In cases of duodenal perforation, surgical closure is the treatment of choice; however, there have been some cases in which the nonsurgical treatment of an iatrogenic duodenal perforation during an endoscopic procedure was effected via endoscopic clipping closure. Here, we report two cases of successful endoscopic clipping closure of an iatrogenic duodenal perforation occur ring during a duodenoscopy insertion for ERCP and endoscopic mucosal resection for the treatment of duodenal adenoma.

This article presents the results of the Implementation Study of the Seoul Cancer Registry, which started in July, 1991 as a population based cancer registry in Seoul, Korea. The completeness and validity of the registered data were evaluated using Mortality/Incidence ratio (M/I ratio), Histologically Verified Cases (HV%), Primary Site Uncertain (PSU%), and Age Unknown (Age UNK%). Owing to the additional active surveillance, the completeness of the data turned out to be fairly acceptable, except for the aged over 75(Mortality/Incidence ratio was over 100%). Eventhough the Seoul cancer registry(SCR) has further way to go in the completeness especially among elderly persons, the validity of SCR data was also acceptable in terms of HV%, PSU%, and Age UNK%. However, PSU% and Age UNK% might need to be further reduced to be comparable with other well established cancer registries. The age standardized incidence rates(ASR) of all cancers between July 1, 1991 and June 30, 1992 were 232.4/100,000 in males and 147.9/100,000 in females. The top five major sites of cancers in Seoul were the stomach, liver, lung, colo-rectum, and bladder in order in males, and the uterine cervix, stomach, breast, colo-rectum, and liver in females. Those 5 cancer sites comprised 68.9% and 64.7% of the total cancer incidence in males and females, respectively.
