PURPOSE: This study aims to determine the correlation between the fracture patterns and the complications in patients with femoral neck fracture treated with internal fixation. MATERIALS AND METHODS: The study comprises 45 patients with femoral neck fracture treated with multiple screws or compression hip screw between May 2008 and April 2012. The mean age was 48 years at the time of the surgery and the mean duration from initial injury to surgery was 20 hours. The fracture patterns were identified according to the anatomical location, the Garden classification and the Pauwels classification. The occurrence of nonunion and avascular necrosis were reviewed with clinical results including Harris hip score and Lunceford hip function test. The correlation between the fracture pattern and occurrence of complications were analyzed. RESULTS: Fracture site union was achieved in 40 hips with the average union time of 17 weeks. Five nonunions occurred which showed high likelihood to occur in subcapital type, displaced (Garden stage III or IV) and Pauwels type III fractures (P<0.05). Avascular necrosis was developed in 10 hips which was mostly in subcapital type and Pauwels type III fracture but no statistical significance was found (P>0.05). The mean Harris hip score was 91 points, and Lunceford functional results were excellent in 15 hips, good in 24, fair in 4 and poor in 2. CONCLUSION: There was high risk of nonunion in subcapital type fracture, displaced fracture (Garden stage III and IV) and vertically oriented fracture (Pauwels type III). Careful attention is needed in these fracture types.

Squamous cell carcinoma infrequently occurs at the soft palate. Although various methods can be used for reconstruction of soft palate defects that occur after resecting squamous cell carcinoma, it is difficult to obtain satisfactory results from the perspective of the functional restoration of the soft palate. A combination of bilateral palatal mucomuscular flap for the oral side and superiorly based posterior pharyngeal flap for the nasal side were performed on two patients who were diagnosed with squamous cell carcinoma of the soft palate in order to reconstruct the soft palate defects after surgical resection. After surgery, the patients were followed-up for a mean period of 11 months. The flaps were well maintained in both patients. The donor site defects were epithelialized and completely recovered. Additionally, no recurrence of the primary sites was shown. Slight hyponasality was observed in the voice assessments that were conducted 6 months after surgery. No food regurgitation or aspiration was observed in the swallowing tests. We used a combination of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap to reconstruct the soft palate defects that occurred after resecting the squamous cell carcinomas. We reduced the donor site complications and achieved functionally satisfactory outcomes.

Journal of the Korean Fracture Society 2017;30(2):75-82
PURPOSE: We evaluated the usefulness of an additional, 2.7 mm mini-locking plate for tibial pilon fractures. MATERIALS AND METHODS: We studied 21 patients (14 males and 7 females), who were treated with a 2.7 mm mini-locking plate via the anterolateral approach for tibial pilon fractures between September 2012 and April 2014. The mean age was 43.85 years, and the mean follow-up period was 16.6 months. The radiologic outcomes were graded by the Burwell and Charnley modified system and clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score and visual analogue scale (VAS) score. RESULTS: The mean union period was 14.3 weeks. At the final follow-up, radiologic results showed 16 excellent results, 4 fair results, and 1 poor result. The average VAS was 3.4 points; the average AOFAS score was 81.8 points. During the follow-up period, there were three cases of posttraumatic osteoarthritis and one case of superficial skin infection. CONCLUSION: Additional anterolateral, 2.7 mm mini-locking plate may be a good treatment method to manage tibial pilon fractures.

BACKGROUND: Although core needle biopsy (CNB) is considered to be the standard technique for histological diagnosis of breast lesions, it is less reliable for diagnosing atypical ductal hyperplasia (ADH). We therefore assessed the characteristics of CNB-diagnosed ADH that are more likely to be associated with more advanced lesions on subsequent surgical excision. METHODS: We retrospectively examined 239 consecutive CNBs, 127 of which were diagnosed as ADH following surgical excision, performed at Asan Medical Center between 1995 and 2010. Archival slides were analyzed for the number of cores per specimen, the number of ADH foci, and the ratio of ADH foci to number of cores (FC ratio). RESULTS: We found that ADH foci in 3 or more cores (p=0.003) and the presence of ADH in 3 or more foci (p=0.002) were correlated with malignancy following excision lesion. Moreover, an FC>1.1 was significantly associated with malignancy in the subsequent excision (p=0.000). CONCLUSIONS: Including the number of ADH foci, the number of cores involved according to ADH, FC ratio, and histologic type in a pathology report of CNB may help in making clinical decisions about surgical excision.

PURPOSE: People with a family history of mood disorder are more likely to have depression. This study compared the characteristics of non-psychotic major depression disorder according to family history of depression. METHOD: Subjects were total of 817 persons recruited for the CRESCEND-K multicenter trial. Characteristics of depression and suicide history of patients with and without a family history of depression were assessed. Family history was determined through self-report. RESULTS: Of 817 participants, 12.4% had a positive family history of depression. Those with family history of depression reported an earlier age at onset of MDD, and more psychiatric comorbidity. Severity of depression and anxiety were not different according to family history of depression. There were no difference in attempted suicide history, number of attempted suicide and age at onset of 1st attempted suicide according to such a family history. CONCLUSION: Patients with family history of depression reported earlier onset of MDD and more history of psychiatric comorbidity.

PURPOSE: The large disparity in outcomes of out-of-hospital cardiac arrest (OHCA) between communities makes it important determine pre-hospital factors associated with outcome of OHCA. The study evaluated pre-hospital care performed by 119 rescuers in OHCA and investigated pre-hospital factors that influenced return of spontaneous circulation (ROSC) and automated external defibrillator (AED) use. METHODS: We retrospectively analyzed 119 OHCA patients with presumed cardiac origin admitted to our emergency department transported by 119 rescuers from May 2007 to April 2010. Patients were divided according to achievement of ROSC and AED use prior to comparative analysis. RESULTS: Twenty six patients (21.8%) experienced ROSC and only five patients (4.2%) survived to discharge. In the study area, scene-to-hospital arrival time was significantly shorter in the ROSC group (15.0+/-5.8 minutes) than the non-ROSC group (19.4+/-9.1 minutes) (p=0.02) and electrocardiography (ECG) application was associated with non-AED use. CONCLUSION: Cooperation of emergency medical services and hospitals in the community to reduce hospital arrival time is needed to improve ROSC in OHCA patients. AED use on scene prior to ECG application will be encouraged and higher level training and continuous education of 119 rescuers for AED use will be needed to enhance AED application.

We report a rare case of the idiopathic membranous glomerulonephritis (IMGN) in association with the thin glomerular basement membrane nephropathy (TGBMN) in a 63-year-old female with hematuria. This is the first case reported in Korea. In renal biopsy of this case, direct immunofluorescence demonstrated anti-IgG Ab along the glomerular capillary wall with granular pattern. The basement membrane was thin, about 170-220 nm and small epimembranous electron dense deposits were observed by electron microscopy. As this case, the combination of TGBMN and IMGN is very uncommon because the IMGN is characterized morphologically by diffuse global thickening of the glomerular capillary wall, while the TGBMN is defined as an extreme thinning of the glomerular basement membrane, less than 200 nm. Our case showed no renal function deterioration and benign prognosis as other reports showed.

BACKGROUND: Legionella pneumophila has been recognized as an important cause of community-acquired pneumonia(CAP) requiring hospitalization. However, epidemiological data on the occurrence of legionella-related pneumonia is unavailable in Korea. The purpose of this study was to evaluated the etiological imprtance of legionella pneumophila serogroup 1 in patients hospitalized with CAP. METHOD: The CAP patient over 16 year-old were recruited from July 1999 to June 2000 at the Chunchon Sacred Heart Hospital. Fifty four patients (male 29, female 25, average age 63.8±15.3) were included in this study. A diagnosis of a legionella pneumophila infection was based on a urinary antigen test using the Binax Company enzyme immunoassay. The severity of pneumonia was assessed using the Fine's PORT scoring system. RESULT: The average Fine's PORT score was 99.7(±44.9). According to the risk classification proposed by the Infectious Disease Society of America, the number of patients in each class(from class I to class V) were 6(11.1%), 13(24.1%), 9(16.7%), 14(25.8%), and 12(22.2%), respectively. Thirty two patients(59.3%) were initially admitted to the intensive care unit. The mortality rate was 16.7%(9 in 54). In all patients, urinary antigens to Legionella pneumophila serogroup 1 were not detected. CONCLUSION: Legionella pneumophila may play little role in causing adult CAP in Korea. Therefore, the routine use of macrolide in the empirical treatment of the CAP patients based upon the ATS guidelines(1993) in Korea should be reevaluated.

BACKGROUND: Atopic dermatitis is a global public health concern owing to its increasing prevalence and socioeconomic burden. However, few studies have assessed the economic impact of atopic dermatitis in Korea. OBJECTIVE: We conducted a cost analysis of atopic dermatitis and evaluated its economic impacts on individual annual disease burden, quality of life, and changes in medical expenses with respect to changes in health related-quality of life. METHODS: The cost analysis of atopic dermatitis was performed by reviewing the home accounting records of 32 patients. The economic impact of the disease was evaluated by analyzing questionnaires. To handle uncertainties, we compared the results with the data released by the Health Insurance Review & Assessment Board on medical costs claimed by healthcare facilities. RESULTS: The direct cost of atopic dermatitis per patient during the 3-month study period was 541,280 Korean won (KRW), and expenditures on other atopic dermatitis-related products were 120,313 KRW. The extrapolated annual direct cost (including expenditures on other atopic dermatitis-related products) per patient was 2,646,372 KRW. The estimated annual indirect cost was 1,507,068 KRW. Thus, the annual cost of illness of atopic dermatitis (i.e., direct+indirect costs) was estimated to be 4,153,440 KRW. CONCLUSION: The annual total social cost of atopic dermatitis on a national level is estimated to be 5.8 trillion KRW.

Methemoglobinemia is a condition in which the iron portion of hemoglobin, which binds to oxygen, is oxidized to produce methemoglobin, which increases blood concentration. There are many causes of methemoglobinemia, the most common being food, drugs, and chemicals. A 75-year-old male patient who had taken an herbicide did not notice any nonspecific symptoms. However, after 4 hours, his methemoglobin levels increased to 17.1%, while after 7 hours it increased to 26.5%, at which time intravenous administration of methylene blue 1 mg/kg (an antidote) was started. After a total of five doses of methylene blue at 1 mg/kg due to reactive methemoglobinemia for about 36 hours, the methemoglobin levels increased to 23.7%. Because no more methylene blue could be administered, 10 g of ascorbic acid (vitamin C) was administered intravenously. After 82 hours, ascorbic acid 10 g was administered six times for repeated reactive methemoglobinemia. No additional reactive methemoglobinemia was observed. The ventilator and endotracheal tube were successfully removed on day 5 after admission.
