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.

BACKGROUND: The persistence of infection by high-risk human papillomavirus (HPV) may lead to cervical cancer. Recently, the American Society for Colposcopy and Cervical Pathology (ASCCP) announced that oncogenic HPV screening and the PAP smear are the main methods of screening for cervical cancer. The goal of this study was to investigate the prevalence and genotyping of HPV, as well as the risk of cervical dysplasia. METHODS: HPV genotyping was conducted by a commercial chip assay. Cervical dysplasia was retrospectively reviewed using electronic medical records. The study participants were grouped together according to cervical dysplasia status: 'no dysplasia,' 'atypical squamous cells of undetermined significance (ASCUS),' 'low-grade squamous intraepithelial lesion (LSIL),' and 'high-grade squamous intraepithelial lesion (HSIL).' The HPV prevalence and genotyping were analyzed according to the cervical dysplasia group. RESULTS: The overall prevalence of HPV was 17.6% (91 out of 518 patients). HPV-18 (2.3%), HPV-16 (2.1%), and HPV-58 (1.2%) were the three most frequent genotypes. The prevalence of HPV infection and the high-risk HPV positive rate was higher in the ASCUS, LSIL, and HSIL groups than in the no dysplasia group (P<0.05). CONCLUSION: In this study, basic data regarding the prevalence and distribution of HPV genotypes were obtained. Since HPV vaccination has been actively encouraged among Korean women, a change in the prevalence of HPV and cervical dysplasia is expected in the future. This study provided basic data describing the prevalence of HPV and its genotypes in the pre-HPV vaccination era.

PURPOSE: To determine the sonographic findings of degenerative change in femoral articular cartilage of the knee by comparative study of specimen sonography and pathology. MATERIALS AND METHODS: We obtained 40 specimens of cartilage of the femur (20 medial and 20 lateral condylar) from 20 patients with osteoarthritis of the knee who had undergone total knee replacement. The specimens were placed in a saline-filled container and sonography was performed using a 10MHz linear transducer. Sonographic abnormalities were evaluated at the cartilage surface, within the cartilage, and at the bone-cartilage interface, and were compared with the corresponding pathologic findings. In addition, cartilage thickness was measured at a representative portion of each femoral cartilage specimen and was compared with the thickness determined by sonography. RESULTS: 'Dot 'lesions, irregularity or loss of the hyperechoic line, were demonstrated by sonography at the saline-cartilage interface of 14 cartilages. Pathologic examination showed that these findings corresponded to cleft, detachment, erosion, and degeneration. Irregularities in the hyperechoic line at the bone-cartilage interface were revealed by sonography in eight cartilages and were related to irregularity or loss of tidemark, downward displacement of the cartilage, and subchondral callus formation. Dot lesions, corresponding to cleft and degeneration, were noted within one cartilage. Cartilage thickness measured on specimen and by sonography showed no significant difference (p=0.446). CONCLUSION: Specimen sonography suggested that articular cartilage underwent degenerative histopathological change. Cartilage thickness measured by sonography exactly reflected real thickness.

Intercoronary arterial connection between normal coronary arteries is a rare variant of coronary anatomy in which there is open-ended circulation. It is distinguished from collaterals seen in the occlusive coronary artery disease. We report a case of bidirectional intercoronary communication between the left circumflex artery and the right coronary artery without occlusive coronary artery disease, but with left anterior descending artery spasm.
