PURPOSE: To investigate the relationship between the varus appearance and the axial alignment of the lower extremity. MATERIALS AND METHODS: The axial alignments of the lower extremities of 46 normal male adults (volunteers) were measured from the radiographs and compared with the reports for Caucasians, and between the groups divided according to their subjective appearance. RESULTS: The femorotibial mechanical angle was 177.4+/-2.4degrees and the medial obliquity of the knee was 94.3+/-2.0degrees, which were the varus compared with the reported reference points. In the group containing those with the subjective varus appearance of the lower extremities, the femorotibial mechanical angle and the medial obliquity of the knee and ankle joint were the varus, and the metaphyseal-diaphyseal angle was greater than in the group containing those with the subjective straight appearance of the lower extremity (p<0.05). CONCLUSION: The axial alignment of the lower extremities of young male adult Korean is the varus, and the subjective varus appearance of the lower extremity is related to the varus axial alignment.

BACKGROUND: Although dendritic cells (DCs) are the most influential antigen presenting cells maturation of DC is the critical control point toward either activation or regulation of immunity. We hypothesized that pretreatment with donor DCs, if which were maturation-resistant in vivo, could enhance engraftment by inducing inactivated state for allo- reactive T cell clones. METHODS: Immature DCs were prepared by 6- day culture of BM cells and we used paraformaldehyde for locking the DCs as immature phenotypes. We did in vitro and in vivo MLR to evaluate the effect of maturation resistant DCs on alloreactive T cells and we confirmed the effect of DCs in MHC full mismatched skin and islet transplantation model. RESULTS: Fixed DCs in immature state were resistant to maturation stimuli and weak stimulator for allo-reactive T cells (CB6F1-->C3H). In contrast, fixed DCs in mature state stimulated allogeneic T cell proliferation effectively. Splenocytes isolated from mice 2 weeks after maturation resistant DC injection could not be reactivated and maintained naive phenotype when cocultured with allogeneic splenocytes (BALB/c-->C57BL6). Consistent with this finding maturation resistant DC treatment suppressed MLR-driven T cell division (CB6F1-->C3H) as assessed by CFSE analysis. But, CD25+ T cells depletion by treatment with anti-CD25 prior to DCs transfer attenuated this regulatory effect of DCs. In a MHC mismatched transplantation model (CB6F1-->C3H), treatment with maturation-resistant DCs 2 weeks before operation, markedly prolonged skin and islet graft survival. But C3H mice pretreated with CB6F1 DCs rejected DBA1 (H-2q) skin graft within 14 days. CONCLUSION: These findings suggest the maintenance of immaturity of DCs is a key factor in modulating alloimmune responses through dendritic cells.

Stress induced cardiomyopathy (SC) is characterized by transient left ventricular (LV) dysfunction in the absence of coronary artery disease. We report on a patient with panhypopituitarism who developed SC resulting from withdrawal of hormonal replacement therapy (HRT). A 52-year-old male visited our hospital for progressively worsening dyspnea. The patient had discontinued HRT 7 days ago, which had been administered for 18 months after transsphenoidal adenomectomy for pituitary macroadenoma. Initial electrocardiogram showed marked sinus bradycardia. Transthoracic echocardiography showed apical ballooning with an LV ejection fraction of 25%. No significant obstructive lesions were observed on coronary angiography. With a clinical diagnosis of SC associated with panhypopituitarism, HRT was restarted, including glucocorticoid and thyroxine, along with standard heart failure management. His LV function had normalized at 2-month follow-up. He remains asymptomatic and administration of beta-blocker and angiotensin converting enzyme inhibitor were discontinued He currently only requires HRT.

Inflammatory bowel disease can progress to colon cancer. However, there is not much of a causal relationship between intestinal tuberculosis and colon cancer. There have been a few case reports of intestinal tuberculosis in association with colon cancer. We experienced a 59-year-old man who had the collision-like pathology of adenocarcinoma and tuberculous lymphadenitis on the sigmoid colon. He visitied our hospital because of abdominal pain and hematochezia. Colonoscopy showed a mass on the sigmoid colon that was causing luminal obstruction. Therefore, sigmoidectomy was performed and the resected specimen revealed a collision-like appearance; the mass was composed of adenocarcinoma invading the proper muscle layer and caseating granuloma in the serosa and lymph nodes. We report here on a case of collision-like pathology that was composed of adenocarcinoma and tuberculosis on the sigmoid colon, and we review the relevant literature.

Mucoceles are common benign cystic lesions of the oral cavity that develop following extravasation or retention of mucous material from the major or minor salivary glands. Mucoceles are usually located in the lower lip (60 to 70% of cases), and the floor of the mouth is only involved in 6 to 15% of cases. Submandibular gland mucocele is extremely rare but should be considered in the differential diagnosis of swelling at the submandibular triangle in young children. We present the rare case of a 16-month-old child who was diagnosed with bilateral submandibular gland mucocele, presenting as serial swellings in both submandibular regions. We removed the cystic mass with the submandibular and sublingual glands to prevent recurrence.

Malignant pericardial mesothelioma is a rare and progressive cardiac tumor. There is no established standard treatment and the prognosis is poor. Most patients were retrospectively diagnosed from surgery or autopsy due to absence of specific clinical manifestation. Most patients with pericardial mesothelioma have demonstrated constrictive physiology on echocardiography or cardiac catheterization. Therefore, pericardial mesothelioma was often misdiagnosed as other causes of constrictive pericarditis. We report a case of primary pericardial mesothelioma misdiagnosed as pericardial metastasis of unknown origin.

BACKGROUND: The purpose of this study was to investigate the clinical and electro physiologic characteristics of patients with multiple accessory pathways. Recently as endocardial mapping has become more and more accurate, multiple accessory pathways which were considered to be rare in the past, have become more commonly reported in patients with Wolff-Parkinson-White syndrome. METHODS: From February 1993 to June 2000, there were a total of 452 patients, who were confirmed to have accessary pathway mediated-tachyarrhythmias diagnosed by electrophysiologic study. Among those, 19 patients had multiple accessory pathways, and were enrolled in this study. RESULTS: Among the 19 patients, thirteen patients were male and six were female, and their mean age was 36.5+/-16.17 years. All patients had 2 accessory pathways. The distribution of the location of the accessory pathways was at the left free wall (71.1%), right free wall (18.4%) and posteroseptal wall (10.5%). The most common combination pattern was the left free wall and left free wall (57.9%) and the most common anatomical areas were the left lateral wall and left posterior wall (36.8%). The success rate of the catheter ablation was 84.2% (16/19). The recurrence rate after the radiofrequency catheter ablation was 31.3% (5/16) and the most common recurrence site was left free wall (60.0%, 3/5). CONCLUSION: These results indicated that the clinical and electrophysiologic characteristics of the multiple accessory pathway patients with WPW syndrome in our study were similar to those of western countries.

An association of carcinoid tumors with another primary neoplasm has been reported in 17~53% of cases, with an especially high incidence of adenocarcinomas. However, simultaneous association of a gastric carcinoid tumor with a gastric adenocarcinoma as a synchronous double primary cancer is extremely rare. We report a case of a synchronous double primary cancer associated with a gastric carcinoid and early gastric cancer in a 63-year-old male patient.
