To evaluate the effectiveness of computed tomography for the differential diagnosis of cervical lymphadenopathy, we reviewed CT scans of 26 patients with cervical lymphadenopathy retrospectively. These included 10 patients with tuberculous lymphadenitis, 11 patients with metastasis and 5 patients with lymphoma, We evaluated the CT scans with a special attention to internal nodal density, feature of contrast enhancement and location of lymphadenopathy. Tuberculous lymphadenitis involved multiple nodes unilaterally and showed central low density with even or uneven rim enhancement, usually occurring in young patients (mean: 31.6 years). Two cases with tuberculous lymphadenitis showed calcifications within the lymph nodes. Lymphoma involved unilateral or bilateral nodes and appeared as conglomerated isodense mass with even rim enhancement. Metastasis involved multiple nodes unilaterally and showed focal, diffuse of mixed pattern of central low density with variable rim enhancement, usually occurring in old patients (mean: 59.4 years). Locations of most frequent lymph node involvements were internal jugular group (76%), spinal accessory group (54%) and retropharyngeal group(12%).

Purpose: Many studies have been conducted on the cause of the medial meniscus posterior horn root (MMPHR) tears. A previous study reported that the relatively large size of the medial femoral condyle (MFC) compared to the size of the medial tibial condyle (MTC) could cause a tear of the MMPHR. The authors conducted a study to confirm that this was correct. Materials and Methods: Patients who underwent magnetic resonance imaging of the knee at our Hospital from March 2011 to April 2019 were divided into a group with a tear of MMPHR and a control group without a tear. The size (MFC, MTC) and relative size ratio of the MFC and the MTC (MFC/MTC) were measured and compared to determine if there was any correlation with the tear of MMPHR. Results: The mean MFC size of the 175 patients with MMPHR tear was 24.6±2.1 mm (0°), 23.5±2.1 mm (30°), 24.1±2.2 mm (60°), and the mean MTC size was 28.2±2.2 mm. The mean size of the MFC of the 147 control subjects was 25.2±2.4 mm (0°), 23.9±2.3 mm (30°), and 24.5±2.6 mm (60°), and the mean size of the MTC was 29.0±2.6 mm. The mean ratios (MFC/MTC) of the 175 patients with MMPHR tears were 0.87±0.05 (0°), 0.83±0.04 (30°), and 0.85±0.05 (60°) for each location. The corresponding mean ratios (MFC/MTC) of the 147 control subjects were 0.87±0.05 (0°), 0.83±0.04 (30°), and 0.85±0.05 (60°). There was no significant difference between the patient group and the control group. Conclusion The size and relative ratio of MFC and MTC do not appear to be related to a tear of the MMPHR.

In most of the previous studies, invasive and discrete techniques have been used to monitor the healing process of the gingival graft. However, Laser Doppler Flowmetry(LDF, floLAB, Moor Instruments Ltd., England) is a non-invasive technique for measurement of blood flow in the tissue and also allows continuous monitoring. Thus, we tested the usefulness of LDF in monitoring the healing process of free gingival graft at gingival recession. Eleven gingival graft site of 7 patients, including 5 males and 2 females, aged between 21 and 41 years (mean age 28.5) were monitored for the blood flow. The blood flow in gingival graft at coronal site, central site, apical site, mesial site and distal site was measured using LDF. Blood flow was measured at 1- week, 2- week, 3- week and 4- week after gingival graft surgery from 10 a.m. to 2 p.m. Time-course of the healing process was evaluated by statistical analysis using repeated ANOVA and Duncan test. The results were as follows : (1) Blood flow stayed increased for 2 weeks, and then, it was a tendency to decrease. (2) The blood flow at distal site had always higher than mesial site during the measuring periods. (3) The blood flow was high orderly after 1 week ; most coronal site, most apical site, central site. But that was high orderly after 2 week, 3 week, 4 week ; most coronal site, central site, most apical site. In conclusion, LDF was a useful and clinically adaptable method to monitor wound healing process. Our study suggested that it was important to protect surgical site to promote initial wound healing.

An 82-year-old woman presented with a 5-year history of erythematous to brown patches and plaques on both legs, arms and trunk. Histopathological findings of biopsy specimens were consistent with mycosis fungoides, and the tumor cells were positive for CD3 and negative for CD20 in immunohistochemical stain. Imaging studies proposed the suspicion of ureter cancer, and the result of cystoscopic biopsy showed papillary urothelial carcinoma. Mycosis fungoides is the most common type of cutaneous T-cell lymphoma, characterized by variable cutaneous manifestations, including patches, plaques, tumors, and erythroderma. There were several studies concerning the evaluation of the second malignancy risk after cutaneous T-cell lymphoma, however the relationship between mycosis fungoides and ureter cancer is not revealed. This patient is considered a case of mycosis fungoides with coincidental ureter cancer.

Neuromyelitis optica (NMO) is an idiopathic inflammatory demyelinating disease, characterized by optic neuritis and myelitis. NMO is a very uncommon and serious neurologic manifestation of Sjogren's syndrome. We report on a 32-year-old female with NMO as central nerve system involvement of Sjogren's syndrome. She had a transverse myelitis ten years ago and did not have symptoms for a long period of time. She visited the emergency center because of worsening weakness of both limbs. She had an appendectomy three days ago before hospitalization. Cervical spinal magnetic resonance imaging showed increased signal intensity in T2-weighted images from the cervical (C2) to the upper thoracic (T4) spinal cord. As serum NMO-IgG was positive, we diagnosed neuromyelitis optica and treated with high dose steroid, but failed. Therefore, we treated with plasmapheresis and the patient was discharged without any neurological deficits.

Common clinical manifestations in patients with IgG subclass deficiency include recurrent respiratory tract infection, recurrent otitis media and sinopulmonary infection by virus or bacteria. The administration of intravenous immunoglobulin (IVIG) has been regarded as the most effective therapy in these patients. We experienced a 22-year-old patient with IgG3 subclass deficiency and recurrent fungal infection of oral cavity and lips. IVIG was given at 0.2g/kg/dose twice a month for 6 months. After treatment with IVIG, the patient improved clinically.

BACKGROUND: Neck circumference, as a predicator of obesity, is a well-known risk factor for obstructive sleep apnea and cardiovascular diseases. However, little research exists on neck length associated with these factors. This study explored the association of neck length with sleep and cardiovascular risk factors by measuring midline neck length (MNL) and lateral neck length (LNL). METHODS: We examined 240 patients aged 30 to 75 years who visited a health check-up center between January 2012 and July 2012. Patients with depressive disorder or sleep disturbance were excluded from this study. MNL from the upper margin of the hyoid bone to the jugular notch and LNL from the mandibular angle to the mid-portion of the ipsilateral clavicle were measured twice and were adjusted by height to determine their relationship with sleep and cardiovascular disease risk factors. RESULTS: Habitual snorers had shorter LNL height ratios (P = 0.011), MNL height ratios in men (P = 0.062), and MNL height ratios in women (P = 0.052). Those snoring bad enough to annoy others had shorter MNL height ratios in men (P = 0.083) and women (P = 0.035). Men with objective sleep apnea had longer distances from the mandible to the hyoid bone to the mandible (P = 0.057). Men with metabolic syndrome had significantly shorter LNL height ratios (P = 0.021), and women with diabetes, hyperlipidemia, and metabolic syndrome had shorter MNL height ratios (P < 0.05). CONCLUSION: This study shows that a short neck by measuring the MNL is probably associated with snoring. In addition, MNL is related to cardiovascular disease risk factors in women.

BACKGROUND: Although osteoporosis is increasing in the elderly population, attempts to analyze the patterns of medical service utilization for osteoporosis are currently not sufficient. The medical services and treatment patterns were investigated using Korea's National Health Insurance claims data, which includes all of the Korean population. METHODS: Through the patient identification algorithm developed by using the administrative claims data in 2007, the adult patients (between 50-100 years) with osteoporosis were identified. The age and gender of the patients who used medical service for osteoporosis were described, in relation with six dichotomous variables. The medical service use patterns such as the type of medical institution and conducting bone mineral density measurement were investigated. RESULTS: The number of patients who used medical service were 1,230,580 (females 89.9%). Sixty one point six percent of the patients were prescribed osteoporosis medicine (indicated for osteoporosis only), and 12.9% of the patients had experienced osteoporotic fracture. The primary medical institutions for treatment were clinics (54.3%), while hospitals were mainly used among the patients with a history of fracture and disease or drug use that may induce secondary osteoporosis. The number of visited medical institutions was 6.4 (as an outpatient) and 0.2 (as admissions) during 6 months. The proportion of patients who conducted bone mineral density measurements within one year before and after the diagnosis of osteoporosis was 66.7% and DXA was the most frequently used densitometry (46.3%). The average number of days for the prescriptions for osteoporosis medicine was 70 days. CONCLUSION: In order to prevent further osteoporotic fractures, appropriate management and treatment should be implemented for osteoporosis patients. To do this, we need to understand the current state of medical service utilization and the treatment of osteoporosis using the National Health Insurance claims data.
