PURPOSE: This study was a descriptive survey research to identify whether characteristics of patients with type 2 diabetes mellitus, their knowledge about diabetes, and self-care behavior impacted on the level of diabetic retinopathy. METHODS: Participants were 133 patients who had type 2 diabetes mellitus and were being seen at a hospital in Korea. The scale for knowledge about diabetes had 24 items, the scale for self-care behavior, 20 items, and the level of diabetic retinopathy was classified according to the international clinical diabetic retinopathy severity measurement standards. RESULTS: The influence of the independent variables on the level of diabetic retinopathy showed that age, job, time since onset of Diabetes Mellitus, regular ophthalmologic examinations, and systolic blood pressure were identified as factors affecting the level of diabetic retinopathy. The explanation power of this regression model was 23.0% and it was statistically significant (F=5.42, p<.001). CONCLUSION: Early education about occurrence of diabetes related diseases, specifically diabetic retinopathy should be provided for patients from younger ages. Moreover, for disease management, social support is needed from co-workers and friends. Efforts to encouraged prevention and delay of diabetic retinopathy should include control of blood sugar and blood pressure.

PURPOSE: Most of recent MR imagings of cerebral cortex activation have been performed by using high field magnet above 2-T or echo-planar imaging technique. We report our experience on imaging of cerebral cortex activation with a widely available standard 1.5-T MR. MATERIALS AND METHODS: Series of gradient-echo images (TR/TE/flip angle :80/60/40 degrees64 x 128 matrix) were acquired alternatively during the periods of rest and task in five normal volunteers. Finger movement (n=10 ;5 right, 5 left) and flashing photic stimulation (n=l) were used as a motor task and a visual task to activate the motor cortex and visual cortex, respectively. Activation images were obtained by subtracting sum of rest images from that of task images. Changes of signal intensity were analyzed over the periods of rest and task. RESULTS: Activation images were obtained in all cases. Changes of signal intensity between rest and task periods were 6.5-14.6%(mean, 10.5%) in the motor cortex and 4.2% in the visual cortex. CONCLUSION: Functional imaging of cerebral cortex activation could be performed with a widely available 1.5-T MR. Widespread applications of this technique to basic and clinical neuroscience are expected.

OBJECTIVES: To evaluate the oncologic and functional results of larynx-preserving partial pharyngectomy (LPP) via lateral pharyngotomy approach as a primary treatment for small (T1 or T2) hypopharyngeal squamous cell carcinoma (HPSCC). METHODS: We performed a retrospective review of 23 patients who underwent LPP through lateral pharyngotomy approach for small HPSCC at the our department between January 1991 and June 2007. Fourteen (61%) patients had adjuvant postoperative radiotherapy. RESULTS: The 2-years and 5-years disease specific survival rate was 77% and 61%, respectively. Nine patients (39%) had tumor recurrence. The most common pattern of recurrence was isolated distant failure (n=4, 44%) followed by local (n=2, 22%) and loco-regional (n=3, 34%) recurrence. The ultimate cure rate of the primary tumor was 87% (20 of 23). Twenty-two of the 23 patients (95%) could be decannulated, tolerate an oral diet, and had acceptable postoperative phonatory function. CONCLUSION: LPP via lateral pharyngotomy approach appears to be a feasible procedure for selected small HPSCC patients in terms of both oncologic and functional outcomes.

Laryngeal chondrosarcoma is a cartilaginous malignant tumor which is rarely encountered in the head and neck. They occur most often in the paranasal sinus, mandibule, and larynx. The cricoid cartilage is the most common site of the laryngeal chondrosarcoma. Complete surgical resection and postoperative radiotherapy are generally recommended. Almost all cases of the laryngeal chondrosarcoma are detected early because of the rapid development of symptoms such as dyspnea, dysphagia and hoarseness, which are caused by the anatomic location. Authors experienced a case of laryngeal chondrosarcoma that originated from the cricoid cartilage in a 67 year-old male without any symptoms. The mass was found on a routine esophagogastroduodenoscopy examination. Hemicricoidectomy with complete excision of tumor was performed via laryngofissure approach. The patient did not undergo radiotherapy, since all margins of the resected mass were tumor-free. There was no evidence of recurrence or metastasis 12 months after surgery.

BACKGROUND/AIMS: Testing for hepatitis B virus (HBV) serologic markers and appropriate vaccination are required in the management of inflammatory bowel disease (IBD) patients. We evaluated immunogenicity for HBV in IBD patients and the response to the HBV vaccination. METHODS: From May 2014 to August 2016, patients diagnosed with IBD were prospectively included and evaluated for antibody to hepatitis B surface antigen, antibody to hepatitis B core antigen, and antibody to hepatitis B surface antigen. Among the 73 patients who were confirmed with nonimmunity to HBV, 44 patients who had completed the 3-dose HBV vaccination series received a single booster vaccination, while 29 patients who had not completed the vaccinations series or were unsure of receiving the vaccination received a full vaccination series. RESULTS: An optimal response was obtained in 70.5% of the patients in the booster group, and 89.7% of the patients in the full vaccination group. Age younger than 26 years (odds ratio [OR], 6.01; 95% confidence interval [CI], 1.15–31.32; P=0.033) and a complete previous vaccination series (OR, 0.15; 95% CI, 0.03–0.80; P=0.026) were associated with optimal vaccine response. Previous complete vaccination series (OR, 0.11; 95% CI, 0.02–0.73; P=0.022) was the only predictive factor for lower compliance. CONCLUSIONS: The response to the HBV vaccination was lower in patients older than 26 years and for those patients with a complete vaccination history. Since patients with a complete vaccination history also had poor compliance, serum HBV-titers should be checked more thoroughly, and a full vaccination series should be administered in cases when there is a negative response to the booster vaccination.

OBJECTIVES: Maternal depression has a detrimental effect on baby growth. Recent reports suggest that depressive symptoms are more likely to occur during pregnancy than in the postpartum period. In Korea, there are relatively few studies of depression during pregnancy compared to those related to postpartum depression. The purpose of this study is to identify factors associated with antenatal depression. METHODS: The study included 143 pregnant women who had completed the Korean version of the Edinburgh Postnatal Depression Scale (K-EPDS), the Korea-Marital Satisfaction Inventory's global distress scale, the Rosenberg Self-Esteem Scale, and the Connor-Davidson Resilience Scale-2. Based on the K-EPDS scores, we divided the participants into two groups. Logistic regression was performed to identify factors associated with antenatal depression. RESULTS: Thirty (21%) of the subjects were evaluated as being depressed, pregnant women. Pregnant women with high self-esteem and marital satisfaction were less likely to have depression. Similarly, those who are younger and those with an abortion history were more likely to have depression. Past psychiatric history and family history were not significantly different between the two groups. CONCLUSION Dissatisfaction with marriage, low self-esteem, younger age, and abortion history were closely related to the presence of antenatal depression. The results of this study can be used as baseline data for the development of family-based education programs and early antenatal depression policies.

Catastrophic antiphospholipid syndrome is a highly fatal condition characterized by widespread thromboembolism subsequent to a triggering factor (e.g., infection, trauma, and neoplasia) in antiphospholipid antibody-positive patients. This paper reports a case of a 29-year-old male without the underlying disease who developed extensive mesenteric thromboembolism and jejunal necrosis during the treatment for acute enteritis. The patient’s condition was improved with low-molecular-weight heparin and an intravenous Ig treatment with emergency surgery. The serum antiphospholipid (anticardiolipin IgM) and lupus anticoagulant antibody tests showed positive results. Acute infectious enterocolitis is generally considered a mild disease. On the other hand, aggressive evaluation and treatment should be considered if the clinical conditions do not improve and deteriorate rapidly despite appropriate antibiotic treatment because of the possibility of acute immunological complications, such as catastrophic antiphospholipid syndrome.
