BACKGROUNDS: With the recent elucidation of genetic basis of Rh blood group, it is now available the molecular genotyping methods for Rh blood typing. These can be used when serological typing is difficult. This study was conducted to investigate the usefulness of Rh genotyping method for Koreans. METHODS: Genotyping for Rh C/c and E/e was performed in peripheral blood DNA samples from 34 blood donors by polymerase chain reaction using sequence-specific primers (PCR-SSP). The PCR determined genotypes were compared with serologically determined phenotypes. RESULTS: The Rh C/c and E/e genotyping results of 34 blood donors were full concordance with the results of their serologic phenotyping. CONCLUSIONS: Rh genotyping method on the basis of Rh genetic model can be applied to Koreans. This genotyping method would be useful tool in prenatal Rh typing of fetus at risk of hemolytic disease and when serotyping is not available for example massive transfusion.

Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

BACKGROUND AND OBJECTIVES: The majority of laryngeal tumors are known to be SCC (squamous cell carcinoma). Non-SCC (non-squamous cell cancers) of the larynx represent a diverse spectrum of diseases with different prognosis and ratio-nales of management from SCC. Therapeutic options to these tumors depend on their histopathological characteristics and clinical behaviors. The purpose of this study was to assess the unique aspects of the non-SCC and to draw diagnosis and provide management options and prognostic variables. MATERIALS AND METHOD: Eleven non-SCC of the larynx from the 212 patients who were diagnosed with larynx cancer during their 3-year visits from 1997 to 2000 were reviewed retrospectively. RESULTS: The incidence of non-SCC was 5.2%. Pathology of non-SCC revealed 3 cases of malignant lymphoma, 2 cases of verrucous cell carcinoma and neuroendocrine carcinoma one case each of basaloid squamous cell carninoma, salivary duct carcinoma, adenocarcinoma, and spindle cell carcinoma. The most common site of origin was supraglottis (6 case, 56.5%), followed by glottis (4 cases, 36.4%) and subglottis (2 cases, 17.2%). Non-Hodgkin's lymphomas and basaloid squamous cell carninoma were treated by chemotherapy. The remaining cases were treated with surgery followed by postoperative radio-therapy or postoperative chemotherapy. The mean follow-up period was 26.8 months (12-43 months). CONCLUSION: Non-SCC accounts for approximately 5.2% of all malignancies of the larynx. Tissue biopsy is the most important diagnostic tool for the non-SCC of the larynx and the tissue sample must be obtained from the deep portion of the submucosal layer. Except for malignant lymphomas, the combined therapy that includes surgery would be the best method of treatment for non-SCC.

OBJECTIVE: There has been no data on health related quality of life (HRQOL) in general Korean population. Assessing factors affecting HRQOL in Koreans is fundamental in HRQOL research. The objective of this study is to assess HRQOL in Korean using Korean version of EQ-5D (KEQ-5D). METHODS: HRQOL was assessed using KEQ-5D from 1,044 randomly selected population representing general Korean population with telephone interview RESULT: The mean KEQ-5D utility score in Korean was 0.88 (range: -0.59~1.00). Sociodemographic data showed relatively higher score in male, younger, well educated, higher income, and white color people. Among a variety of diseases, gastric ulcer/gastritis, arthritis, hypertension diabetes, low back pain were common in Korea. The most significant chronic diseases influencing Koreans were gastrointestinal disorder and arthritis. CONCLUSION: This paper suggests basic information on HRQOL in Korean and can be a useful parameter in comparison in the future research.

BACKGROUND/AIMS: We aimed to investigate the prevalence and possible causes of hypouricemia in the Korean population and to compare our findings with published results of other populations. METHODS: We examined the serum uric acid levels of 30,757 subjects who had their uric acid values measured at least once during a 1-year period. All individuals with hypouricemia (serum uric acid < 2.0 mg/dL, n = 424) were reviewed with respect to medical drug history and concomitant diseases previously identified as being associated with hypouricemia. RESULTS: The prevalence of hypouricemia was 4.14% (299/7,223) among inpatients and 0.53% (125/23,534) among outpatients, for an overall prevalence of 1.39% (424/30,757). Possible causes associated with hypouricemia were found to be solid or hematologic malignancies (n = 86), diabetes mellitus (n = 56), and therapeutic drugs (n = 29). The medications were allopurinol (n = 11), angiotensin II receptor blockers (n = 10), salicylates (n = 6), febuxostat (n = 1), and warfarin (n = 1). In the remaining 226 individuals, the cause of hypouricemia was not identified. CONCLUSIONS: Hypouricemia is relatively common in the Korean population compared to those of other countries. The possible causes associated with hypouricemia are related to underlying diseases and medications.

Most intussusceptions occur in children under 1 year of age whereas 5%~10% occurs in adults. Although intussusception has an acute occurrence in children, symptoms in adults may be subacute or chronic, and the diagnosis is often delayed. In contrast to adults, intussusception in children is the most common cause of intestinal obstruction, and one of the most frequent causes of surgical emergencies. While idiopathic cases account for more than 90% of those seen in children, many cases in adults are generally related to neoplasm. However, intussusception due to a primary malignant lymphoma of the small intestine is a rare clinical condition. There is little information on the role of colonoscopy in colonic intussusception. Two cases are herein reported, of malignant lymphoma in the ileocecal region causing intussusceptions in which the diagnosis and reduction of intussusception were made by colonoscopy. Colonoscopy plays a useful role in the diagnosis and management of intussusception. The clinical, radiographic, endoscopic, and pathologic findings are described with brief reviews of related literature.

STUDY DESIGN: A retrospective study to analyze the results of posterior lumbar interbody fusion, using laminar bone and titanium block, with pedicle screw instrumentation. OBJECTIVES: To evaluate the clinical and radiological results of posterior lumbar interbody fusion, using laminar bone and titanium block, with pedicle screw instrumentation. SUMMARY OF LITERATURE REVIEW: Several studies have demonstrated the results of posterior lumbar interbody fusion, there has been no report on our method. MATERIALS AND METHODS: From March 2001 to May 2002, seventeen patients were treated by posterior lumbar interbody fusion, using laminar bone block, from spinous process and titanium block. All patients were clinically followed up over 12 months. The mean age of the patients and follow-up were 58 years and 15 months, respectively. The clinical results were evaluated by Kim's criteria and radiological union, and the subsidence of disc space and change of the lordotic curve were assessed by a simple Xray. RESULTS: The satisfactory clinical result and radiological union rates were 83.3 and 90.4%, respectively. The mean subsidence of the disc space and change of the lordotic curve were 0.8 mm and 1.6 degrees, respectively. There was one complication of a wrong insertion of the pedicle screw to the disc space. CONCLUSION: Posterior lumbar interbody fusion using laminar bone and titanium block showed an acceptable radiological union rate and clinical results. This could be a good alternative method for obtaining initial stability and bony union without taking a bone graft from the posterior ilium in various spinal lesions.
