The etiology of spontaneous hemarthrosis of the knee joint in elderly pattents is still unknown. This report discusses seven spontaneous hernarthroses, three that were managed witla conservative measures such as aspiration, rest and knee immobilization because of poor general condition and four in which arthroscopic evaluation and treatment were performed. These patients were elderly indi.viduals without an obvious history of trauma. The roentgenograms of each involved knee demonstrated degenerative osteoarthritic changes of knee joint. Arthroscopic examination revealed denuded articular cartilage and subchondral bone exposure in four operative cases and degenerative meniscal tear in one case of four. These patients underwent mthroscopic debridement and did not experience recurrenees of the hemarthrosis. We think that the origin of the bleeding was most likely from the subchondral cancellous bone which was exposed due to degenerative change of the knee joint and the senile changes of the vessels around the knee joint with aging process may contribute the spontaneous bleeding into the knee joints.

In anesthetized cats the effects of lactate-activated muscle spindle upon the group Ia muscular afferent fibers were studied. Laminectomy was done from L5 to Sl spinal cord level. Extracellular recording was done at dorsal root to record the impulse discharge from group Ia muscular afferent fibers. 1) Muscle spindle of Gastrocnemius-Soleus muscle were activated by lactate injection and exhibited increased impulse discharge through group Ia muscular afferent fibers. 2) There was latency of 7-12 seconds before muscle spindle is activated by lactate injection. But the whole response was not dose related. 3) The response pattern after lactate injection was divided into three groups which were excitation, inhibition and inhibition with preceding excitation. 4) Some responses were similar to those of bradykinin, sympathetic stimulation (adrenaline injection) and succinylcholine injection. 5) It was suggested that muscle spindle has characteristics of polymodal receptor which has responses to not only mechanical stimulation but also chemical stimulation.

BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.

PURPOSE: A pancreaticoduodenectomy is the procedure of choice for patients with resectable carci nomas of the pancreatic head, duodenum, or periampullary region. Although the morbity and the mortality are decreasing now, but there are still high. Leakage of the pancreatic duct remains the major source of death and complications after a pancreaticoduodenectomy. Thus, the authors used a stented pancrea ticojejunostomy and jejunojejunostomy after a pancreaticoduodenectomy to decrease leakage of the pancreatic duct. METHODS: The authors studied retrospectively 44 consecutive patients who had a pancrea ticoduodenectomy with a stented pancreaticojejunostomy and jejunojejunostomy at Kwangju Christian Hospital between 1993 and 1998. RESULTS: Leakage of the pancreaticojejunostomy was diagnosed in one of the 44 patients (2.5%). There were two deaths after the pancreaticoduodenectomy, one from compli cation of leakage of the pancreaticojejunostomy and the other from UGI bleeding. CONCLUSION: The stented pancreaticojejunostomy and jejunojejunostomy is an effective and safe method for use with a pancreaticoduodenectomy. However, the leakage that might occur despite the stented pancreaticojeju nostomy and jejunojejunostomy can be managed less invasively.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

BACKGROUND: It is well known that systemic blood pressure oscillates with low(0.04~0.1Hz), mid(0.1~0.15Hz), and high(respiratory) frequency range. But there has been no study about oscillation of pulmonary artery pressure(PAP). METHOD: We measured PAP for 5 minutes in 32 patients of ventricular septal defect and stored them to computer files. Power spectral density curve was obtained. Low, mid, respiratory frequency power were measured by integrating the area within each frequency range below the power density curve. RESULT: The incidence of significant low frequency power(more than 5% of total power) were higher in patients of high PAP and hign Rp/Rs than those of low PAP and Rp/Rs(p<0.01 and p<0.005 respectively). The low frequency power positively correlates with PAP and Rp/Rs(r=0.62, p<0.0005 and r=0.61, p=0.0005 respectively). CONCLUSION: It can be said conclusively that as PAP and pulmonary vascular resistance elevates, the PAP tends to definitively oscillate in low frequency range.
