Fatal complications including cerebral edema and neurologic collapse occur during treatment of diabetic ketoacidosis(DKA). A 6-week-old female infant with fever, dehydration and drowsy mental status was diagnosed as DKA and neurologically deteriorated during treatment. The cranial computed tomography scan revealed multifocal brain infarctions of the left caudate nucleus, bilateral frontal periventricular white matter, and right parietal cortex. A moderate amount of hemorrhage was also noted in both lateral ventricles. She recovered rapidly with supportive treatment over time. The clinical course and radiologic findings of this patient emphasize the importance of brain infarction as a cause of persistent neurologic loss in children with DKA.

PURPOSE: We wanted to evaluate the normal glenoid size of Koreans in their 7th and 8th decades by conducting Computed tomographic (CT) studies. MATERIALS AND METHODS: The CT images were obtained from the normal scapulae of the patients (mean age: 68.8) who had humeral fracture. A display workstation version 2.0.73.315 was used to measure the scans to determine the maximal superoinferior (SI) and anteroposterior (AP) diameters of the glenoid vault. RESULTS: The average diameters of curvature of the glenoid were 31.2 mm (range: 27 to 34 mm) in the superior-inferior direction and 26.1mm (range: 22 to 31mm) in the anterior-posterior direction. CONCLUSION: This study showed the normal glenoid size of Koreans and it is different from the size that the international literature reported. It should be an important factor for the treatment of fracture or in designing arthroplasty implants.

PURPOSE: We wanted to evaluate the effectiveness of posterolateral approach for open reduction and internal fixation of posterior malleolar fragment with trimalleolar fracture of ankle joint. MATERIALS AND METHODS: There were 27 cases of trimalleolar fracture in our hospital from Jan. 2005 to Dec. 2007. We investigated 10 patients who underwent operation with the posterolateral approach. The mean follow up period was 20 (6-36) months. Preoperative posterior malleolar fragment involved above 25% of articular surface in 10 cases and displaced more than 2 mm in 4 cases. We analyzed the radiologic type of posterior malleolar fragments and complications, and evaluated the AOFAS score. RESULTS: All cases showed primary union mean 11.8 (8-14) weeks. The complication focal skin necrosis in one case and all patients showed excellent AOFAS score. CONCLUSION: The posterolateral approach may be a useful for open reduction and internal fixation of posterior malleolar fragment with trimalleolar fracture, especially simultaneous management of lateral malleolar fracture.

Diabetes has been associated with more severe outcomes and higher mortality in coronavirus disease 2019 (COVID-19) patients compare to morbidity and mortality in patients without diabetes. Several mechanisms may play a role in this greater morbidity and mortality, especially uncontrolled hyperglycemia, an impaired immune system, pre-existing proinflammatory states, multiple comorbidities, and dysregulated angiotensin-converting enzyme 2 signaling. Thus, the diabetes medical community emergently needs to know about COVID-19 and its effects on patients with diabetes, as they must take precautions to carefully manage these patients during the COVID-19 pandemic. The Korean Diabetes Association provides some guidance and practical recommendations for the management of diabetes during the pandemic. This report provides insight into the association between diabetes and COVID-19, proper management of diabetes in patients with COVID-19 and an official suggestion by the Korean Diabetes Association for managing the COVID-19 outbreak.

BACKGROUND: Concerns of patients on sexual activity after total hip arthroplasty have not been well studied in Asian patients. This study aimed to determine the following: (1) what are the concerns of patients related to sexual activity after total hip arthroplasty? (2) what are the changes in sexual activity after total hip replacement in Korean patients? METHODS: Details of sexual activity and concerns were obtained using a questionnaire designed specifically for the study. The questionnaire was administered to 64 patients in a face-to-face interview at an outpatient clinic. RESULTS: Preoperatively, 53.1% of patients experienced difficulties, primarily due to hip pathology and limitations of motion. The median time to the resumption of sexual activity was 3 months postoperatively, and most patients had no increase in the frequency of sexual activity after the total hip replacement. In 39.1% of patients were seen having difficulties with leg positioning following total hip replacement, and they were likely to change coital positions. The most common concern regarding sexual activity of patients was the fear of dislocation. Furthermore, patients with a higher stress level had lower satisfaction rates. Most patients were unable to obtain information on sexual activity following the total hip arthroplasty, and they did not consult with a physician due to the private nature of the topic. CONCLUSIONS: Dislocation was the most common concern of patients during sexual activity following a total hip arthroplasty, and a higher stress level was found to be associated with a lower satisfaction rate. Because most patients were unprepared to consult a physician, the provision of appropriate information before a consultation might be beneficial.

PURPOSE: This is a retrospective descriptive study to determine the incidence of congenital heart disease(CHD) in Jeju and to estimate the suitability of the Jeju population as the subject for a regional birth cohort study. METHODS: All patients with CHD diagnosed by two dimensional echocardiography in Cheju National University Hospital and Halla General Hospital from January 1999 to March 2003 were included in this study. RESULTS: From April 1999 to March 2002, the crude incidence rate was 10.06 per 1,000 live births (236 cases/23,464 live births). Among the 236 cases, the proportion of each type was as follows: Ventricular septal defect(44.9%), atrial septal defect(21.2%), pulmonary stenosis(11.0%), patent ductus arterios us(9.3%), tetralogy of Fallot(3.4%), transposition of great arteries(2.1%), aortic stenosis(1.3%), hypoplastic left heart syndrome(1.3%), coarctation of aorta(0.8%), total anormalous pulmonary venous return(0.8%), tricuspid atresia(0.8%), heterotaxia(0.4%), single ventricle(0.4%), atrioventricular septal defect(0.4%), Ebstein anomaly(0.4%). The male to female ratio was 1:1.380(P=0.011). For unknown reasons, females showed significantly higher incidence in VSD(P=0.005) and PDA(P=0.019). Mortality rate was 0.34 per 1,000 live births. The types of VSD were 72.1% of perimembranous, 16.4% of trabecular muscular, 5.7% of subarterial, and 5.7% of unknown. CONCLUSION: This is the first regional study on the incidence of CHD in Korea. The incidence of CHD in Jeju was 10.06 per 1,000 live births. Most of our cases were VSDs and ASDs. Jeju would be a good subject for a regional cohort study in the future.

BACKGROUND: Phospholipase C (PLC) plays an important role in cellular signal transduction and is thought to be critical in cellular growth, differentiation and transformation of certain malignancies. Two second messengers produced from the enzymatic action of PLC are diacylglycerol(DAG) and lnositol 1, 4, 5-trisphosphate(IP3). These two second messengers are important in down stream signal activation of protein kinase C and intracelluar calcium elevation. In addition, functional domains of the PLC isozymes, such as Src homology 2(SH2) domain, Src homology 3(SH3) domain, and pleckstrin homology(PH) domain play crucial roles in protein translocation, lipid membrane modification and intracellular memrane trafficking which occur during various mitogenic processes. We have previously reported the presence of PLC-γ1, γ2, β1, β3, and δ1 isozymes in normal human lung tissue and tyrosine-kinase-independent activation of phospholipase C-γisozymes by tau protein and AHNAK. We had also found that the expression of AHNAK protein was markedly increased in various histologic types of lung cancer tissues as compared to the normal lungs. However, the report concerning expression of various PLC isozymes in lung cancers and other lung diseases is lacking. Therefore, in this study we examined the expression of PLC isozymes in the paired surgical specimens taken from lung cancer patients. METHODS: Surgically resected lung cancer tissue samples taken from thirty seven patients and their paired normal control lungs from the same patients. The expression of various PLC isozymes were studied. Western bolt analysis of the tissue extracts for the PLC isozymes and immunohistochemistry was performed on typical samples for localization of the isozyme. RESULTS: In 16 of 18 squamous cell carcinomas, the expression of PLC-γ1 was increased. PLC-γ1 was also found to be increased in all of 15 adenocarcinoma patients. In most of the non-small cell lung cancer tissues we had examined, expression of PLC-δ1 was decreased. However, the expression of PLC-δ1 was markedly increased in 3 adenocarcinomas and 3 squamous carcinomas. Although the numbers were small, in all 4 cases of small cell lung cancer tissues, the expression of PLC-δ1 was nearly absent. CONCLUSION: We found increased expression of PLC-γ1 isozyme in lung cancer tissues. Results of this study, taken together with our earlier findings of AHNAK protein-a putative PLD-γ, activator-over-expression, and the changes observed in PLC-δ1 in primary human lung cancers may provide a possible insight into the derranged calcium-inositol signaling pathways leading to the lung malignancies.

PURPOSE: Langerhans cell histiocytosis (LCH) is a disorder characterized by the proliferation of activated Langerhans cells. Although current therapies are very effective at inducing remission, multiple recurrences and long-term sequelae are common for young patients. For this reason, more effective therapies based on the pathogenesis of LCH are needed. We investigated the use of 2-chlorodeoxyadenosine (2-CdA), a purine analogue with an antiproliferative effect on histiocytes and lymphocytes, in patients with recurrent or refractory LCH. METHODS: Four children with recurrent or refractory LCH received 2-CdA (5~7 mg/m2/day for 5 days, given as a 24-hr continuous infusion and repeated every 21~28 days for 5~7 courses). RESULTS: All four patients had multiorgan involvement, and were heavily pretreated. Of the two children with recurrent diseases, one had complete response and the other showed no active disease except for the remaining diabetes insipidus. Two infants who showed poor early response to previous combination chemotherapy also responded poorly: partial response in one, and progressive disease resulting in death in the other. Toxicity consisted mainly of myelosuppression, but significant infections did not occur. The peripheral neuropathy was not seen. CONCLUSION: 2-CdA, tolerable in children without significant side effects, might be effective for the treatment of recurrent LCH in children. However, the efficacy in infants with multi-system, refractory diseases needs further study. The feasibility of 2-CdA treatment as the first-line therapy for high-risk diseases, and the possibility of combination with other agents needs to be addressed in the future.
