The Korean Diabetes Association (KDA) published the 3rd edition of the diabetic neuropathy management guidebook in 2010. This publication has been recognized as the definitive guide for the clinical management of diabetic neuropathy in the Korean medical system. In this report, we provide a modified summary of the 3rd edition of the diabetic neuropathy management guidebook. We hope this summary will serve as a helpful reference in the daily clinical practice of diabetes care.

BACKGROUND: Sternal fractures are relatively rare, and caused mainly by blunt anterior chest wall trauma. In most cases, sternal fractures are treated conservatively. However, if the patient exhibits problematic symptoms such as intractable chest wall pain or bony crepitus due to sternal instability, surgical correction is indicated. But no consensus exists regarding the most appropriate surgical method. We analyzed the results of surgical fixation in cases of sternal fracture in order to identify which surgical method led to the best outcomes. METHODS: We retrospectively reviewed the medical records of patients with sternal fractures from December 2008 to December 2011, and found 19 patients who underwent open reduction and internal fixation of the sternum with a longitudinal plate (L-group) or a T-shaped plate (T-group). We investigated patients' characteristics, clinical details regarding each case of chest trauma, the presence of other associated injuries, the type of open reduction and fixation, whether a combined operation was performed, and postoperative complications. RESULTS: Of the 19 patients, 10 patients (52.6%) were male, and their average age was 56.8 years (range, 32 to 82 years). Seven patients (36.8%) had isolated sternal fractures, while 12 (63.2%) had other associated injuries. Seven patients (36.8%) were in the L-group and 12 patients (63.2%) were in the T-group. Three patients in the L-group (42.9%) showed a loosening of the fixation. In all patients in the T-group, the fracture exhibited stable alignment. CONCLUSION: Open reduction and internal fixation with a T-shaped plate in sternal fractures is a safer and more efficient treatment method than treatment with a longitudinal plate, especially in patients with a severely displaced sternum or anterior flail chest, than a longitudinal plate.

BACKGROUND: Monitoring the "depth of anesthesia" is an ongoing problem. To identify a useful parameter for determining the depth of anesthesia with enflurane, EEG data was obtained using a Physiolab 800. METHODS: Variations in EEG signals were measured and analyzed by the stage of anesthesia. EEG data was obtained from 15 patients during general anesthesia with enflurane. The EEG signal was acquired and analyzed in 5 steps (one day before anesthesia, during induction, during skin incision, at end of anesthesia, and one day after anesthesia). Fp1 electrode and the EEG data mainly from the forehead were used to determine the depth of anesthesia using EEG characteristics during enflurane anesthesia. All data were preprocessed by filtering, baseline correction and using the linear detrend method to reliable analyze of sample data in the surgical environment. Data obtained were transformed to frequency and power spectrum analysis was performed. RESULTS: alpha, beta, delta and theta waves were detected by frequency area separation and the trend of each wave was observed during each anesthesia stage. EEG data was slowed down and the theta wave ratio increased as the depth of anesthesia increased. Accordingly, spectral edge frequency (SEF) and median frequency (MF) were used as parameters to determine the depth of anesthesia. The frequencies of SEF and MF decreased during anesthesia and returned to the preanesthetic level after the cessation of anesthesia. CONCLUSIONS: Our results suggest that SEF and MF can contribute as useful parameters to determine the depth of anesthesia. Anesthetics not only affect the central nervous system, but also affect the autonomic nervous system. If the autonomic nervous system signals such as heart rate variability are taken into account, more reliable evaluations would be possible.

For many years, NO2 has been regarded as one of the elements among indoor air pollutants of urban homes, leading to increased public concerns on this gas. For the purpose of preparing the fundamental data for the evaluation and control of health effect relevant to NO2 levels, authors measured the indoor (kitchen, living room, bedroom) and outdoor NO2 levels categorized by the type of house(apartment, detached dwelling) and cooking fuel(L.P.G., briquette) in the winter and summer, and surveyed the variables(kitchen ventilation, family size, parental smoking) may effect the indoor NO2 levels. The level of NO2 was measured by Palmes tube, and this survey was carried out at 110 homes in the Pusan area from October 1984 to September 1985. The obtained results were as follows: 1) The mean indoor and outdoor NO2 level in winter and summer, respectively, was 0.029+/-0.012 ppm and 0.022+/-0.012 ppm in the kitchen, 0.022+/-0.009 ppm and 0.018+/-0.010 ppm in the living room, 0.017+/-0.008 ppm and 0.016+/-0.010 ppm in the bed room, and 0.021+/-0.007 ppm and 0.016+/-0.007 ppm outdoors. 2) In the category of the type of house and cooking fuel, the highest mean indoor and outdoor NO2 level in the winter was in apartments using briquettes, and in the summer, the highest level was in apartments using L.P.G. 3) In the category of the type of house, the mean indoor and outdoor NO2 level in the winter and summer was higher in the apartment group compared to detached dwelling. 4) In the category of the type of cooking fuel, the mean indoor and outdoor NO2 level in the winter was higher in the briquette group, and in the summer, the L.P.G. group was higher. 5) In the category of the kitchen ventilation, family size, parental smoking and asthma attack history of children, there was an insignificant difference in the indoor NO2 levels.

The aim of this study is to develop an animal model of polyps that is more suitable for further polyp studies by semiquantitatively analyzing the effects of Pseudomonas aeruginosa infection and/or mechanical trauma to the sinus mucosa, based on the epithelial rupture theory, on polyp formation in the rabbit maxillary sinuses. The natural ostia were occluded in 30 Pasturellafree New Zealand white rabbits. All rabbits were divided into three groups according to the following modes of manipulation on the right maxillary sinus: inoculation with P. aeruginosa (group A), brushing of the sinus mucosa (group B), and inoculation with P. aeruginosa accompanied by brushing of the mucosa (group C). The left maxillary sinuses were used as the control. After four weeks, macroscopic polyps and light microscopic polyps and/or polypoid mucosa were semiquantitatively analyzed. The number of macroscopic polyps per sinus was significantly larger in groups A (1.0 polyps) and C (1.3 polyps) than in group B (0.0 polyps). Microscopic examination revealed significantly higher levels of polyps and/or polypoid mucosa in groups A and C than in group B. The results of this study suggest that a rabbit model of polyps using P. aeruginosa is suitable for further polyp studies and that induction of this type of model needs no mechanical trauma to the sinus mucosa.

PURPOSE: CEA, CA19-9, and CA72-4 are the most commonly used tumor markers in stomach cancer. This clinical study was performed to evaluate the diagnostic value of these tumor markers in stomach cancer patients. MATERIALS AND METHODS: A retrospective analysis of 170 stomach cancer patients who had undergone curative gastrectomy between January 1991 and December 1996 at the Department of Surgery was performed. The preoperative and postoperative serum levels of these tumor markers were measured in 170 patients. RESULTS: The preoperative positive cases were 28 cases (16%) in CEA, 15 (9%) in CA19-9, and 24 (14%) in CA72-4. The postoperative positive cases among 48 recurrences were 21 cases (44%) in CEA, 10 (21%) in CA19-9, and 10 (21%) in CA72-4. The combination of CEA with CA19-9 or CA72-4 had higher positivity rate (58%) than single tumor marker. The highest positivity rate was found in CEA at recurrences of anastomotic site, in CA19-9 at recurrences of lymph node, in CA72-4 at peritoneal seeding and distant metastasis. In multivariate analysis, these tumor markers were not independent prognostic factors. CONCLUSION: CEA, CA19-9, and CA72-4 have proved unhelpful in initial diagnosis of stomach cancer because of their low positivity rate. And the combination of 3 tumor markers was the useful method for raising positivity rate in diagnosis of recurrences.

Antithyroid drugs (ATD) has been widely used to treat Graves' disease. However agranulocytosis, a serious fatal complication of ATD treatment, occurs in about 0.5 percent. The symptoms may mimic viral infections (fever, sore throat), and the potentially life-threatening pyogenic infections can go unrecognized initially. The median duration of drug exposure before the onset of acute agranulocytosis is within 30 days in most cases. We report a case of agranulocytosis with secondary soft tissue infection and abscess occuring after increasing the dose of methimazole in a woman who had taken methimazole for more than 10 years. We administered broad-spectrum antibiotics and aspirated the soft tissue abscess. A review of the medical literature regarding agranulocytosis in the setting of ATDs is presented.
