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.

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.

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.

Pantoea infections are rare in humans and an unusual cause for sepsis in immunocompetent patient. It is a gram-nagative bacillus of the family Enterobacteriaceae. Infections are usually associated with plant thorn injury or outbreak traced to comtaminated parenteral nutrition. We experienced a case of pantoea species cholecystitis and cholangitis with bacteremia. The patient was administrated intravenous antibiotics, and then patient was improved.

OBJECTIVES: With the rapid increase in the prevalence of diabetes, the age groups of diabetic patients are becoming diversified. This study will examine the degree of obesity, insulin resistance, and insulin secretion ability among patients first diagnosed with diabetes according to age and gender. METHODS: The subjects of this study included 616 patients who were first diagnosed with diabetes during a routine physical examination. This sample was obtained from a total of 28,075 adults aged 19 years and older who received the examination among 33,829 participants in the Korea National Health & Nutrition Examination Survey (KNHANES) from 2007–2010. The subjects were categorized by age into young age (age: 19 – 39 years), middle age (age: 40 – 59 years), and old age (age: 60 years and older). The degree of obesity was categorized according to body mass index (BMI) into normal weight (BMI: 18.5 ~ 22.9), overweight (BMI: 23 ~ 24.9), and obesity (BMI: 25 or above). Insulin resistance was evaluated by homeostatic model assessment of insulin resistance (HOMA-IR). RESULTS: It was found that 14.1% (n = 87) of a total of 616 subjects (324 men, 292 women) were in the young age group, 43.8% (n = 270) were in the middle age group, and 42.1% (n = 259) were in the old age group. In addition, 83.3% of men that were overweight or obesity were in the young age group, while 79.2% and 60.5% were in the middle age and old age groups, respectively. A total of 82.2% of women that were overweight or obesity were in the young age group, while 79.5% and 77% were in the middle age and old age groups, respectively. For men, the more obesity they were in all age groups, the higher their HOMA-IR. For women, the more obesity they were in the young age and middle age groups, the higher their HOMA-IR; however, women in the old age group showed the highest HOMA-IR when they were of normal weight. CONCLUSION: Among diabetic patients first diagnosed with the disease in Korea, the youth population had the highest obesity rate. Insulin resistance increases as an individual's weight increases among those patients who are first diagnosed with diabetes; the only exception noted is for elderly women.
