Anaphylactic deaths are frequently observed at autopsies. Since death associated with medical practice has become social concern, the identification of anaphylactic shock is an important part of forensic medicine. However, autopsy findings of anaphylactic shock are usually non-specific; therefore, the diagnosis of anaphylactic shock must be inferred from collecting data on the past history of the deceased, circumstances of death, and negative autopsy findings. The analysis of serum mast cell tryptase level is a well-known, useful ancillary test for the diagnosis of anaphylactic shock, but is not widely used in daily practice in Korea. We recently encountered 2 autopsy cases of anaphylactic shock and confirmed that analysis of serum mast cell tryptase level was useful for the diagnosis of anaphylactic shock. In this report, we present these 2 autopsy cases of anaphylactic shock, with literature review of the usefulness and limitations of serum mast cell tryptase analysis.

Basal cell carcinomas usually arise from the epidermis and show some epidermal connections. It is very unusual that basal celi carcinomas occur as subderrnal mass without epidermal connections. A 51 year-old female h;d an asymptomatic skin colored indurated plaque with linear old scar on the left side of nose fcr about 20 years. She had had a tumor that supposed to be a epidermal cyst, on the same site and the lesion was excised about 20 years ago. We performed the punch biopsy on her first visit which revealed hypertrophic scar. She was treated with intralesional injection of triamcinolone acetonide to reduce the size of hypertrophic scar. However, the lesion had not been reduced. She underwent the surgery to remove the scar at plastic surgery and the excisional biopsy showed a subdermal basal cell carcinoma. We recommend that the newly developed skin tumor in the pre-excised region should be required excisional biopsy instead of punch and close observation

PURPOSE: To translate and evaluate the reliability and validity of the Korean version of the National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25). METHODS: Two bilingual ophthalmologists independently translated the original English version of the NEI-VFQ-25 into written Korean. A panel of the Korean Retina Society reviewed the translations to form a single reconciled forward translation of the Korean version of the NEI-VFQ-25. Another ophthalmologist back-translated this first draft into English. Both the first draft and back-translated draft were edited by a professional translator. To evaluate the correlation and validity, results between the original NEI-VFQ-25 and the Korean version, completed by the bilingual participants, were compared. RESULTS: The Korean version of the National Eye Institute Visual Functioning Questionnaire-25 was developed by translation, back-translation, and expert supervision. Results from 23 bilingual participants between the original NEI-VFQ-25 and the Korean version were compared and showed statistically significant correlation, with a Spearman's correlation coefficient of 0.4 or greater. The Kolmogorov-Smirnov test results showed no statistically significant differences between the two questionnaires. CONCLUSIONS: Translation and validation of the Korean version of the NEI-VFQ-25 was achieved.

Osteoma is the most common benign tumor of the paranasal sinuses and the frontal sinus is the most frequently involved site. Osteomas are slow growing osteoblastic lesions commonly seen in the outer table of the calvarium, the mandible, the frontal and ethmoid sinus, and occasionally in tubular bones. They are usually detected during the second to fifth decades of life, and reported ratio of male to female is 1.5:1 to 2:1. The symptoms of osteomas are usually developed as gradual growth. They are headaches, facial pain, proptosis, decreased visual acuity, chemosis, diplopia, epiphora, nonpulsating exophthalmus, and transient blindness. Posterior intracranial extension of a frontoethmoid osteoma may lead to brain abscess, intracranial mucocele, tension pneumocephalus. We experienced a 60-year-old male patient who came to the emergency room with acute and severe left periorbital swelling, red eye, and epiphora lasted for 10 days. In a plain radiographs and computerized tomographic scans, a 2.5 x 2.5 x 3.0 cm well marginated mass impressed by osteoma in frontoethmoidal sinus was detected. After the symptoms subsided by conservative treatment, total excision was made by bicoronal approach. Authors reported a frontoethmoidal osteoma presenting periorbital cellulitis without orbital mucocele, which is very rare symptom.

BACKGROUND: Reperfusion of ischemic myocardium has been postulated to result in a specific oxygen radical mediated tissue injury. Iron may liberate during ischemia and we hypothesized that administration of the iron chelator, deferoxamine during ischemia would result in improved recovery after postischemic reperfusion. PURPOSE: To test whether iron-catalyzed processes contribute to myocardial necrosis during ischemia and reperfusion, deferoxamine was administered to block iron catalyzed hydroxyl radical formation in rabbits. METHODS: Eleven rabbits were divided into two groups: control group (n=5) and deferoxamine pretreatment group (n=6). the left circumflex coronay artery was ligated for 30 minutes and reperfused for 180 minutes. Area at risk (AR) was measured by non-stained area with ethylene blue injection into left atrium after left circumflex coronary artery ligation. Infarct size was measured by weighing after tripheyltetrazolium chloride staining. Heart rate was measured using electrocardiographic recording and systemic blood pressure was monitored by pressure transducer connected to the catheter in the left ventricle. RESULTS: 1. There was no significant difference of heart rate and blood pressure in deferoxamine pretreatment group compared with control group. 2. There was significant decrease of serum iron concentration after continuous infusion of deferoxamine compared with serum iron concentration before ligation of coronary artery (P<0.05). 3. There was no significant difference of area at risk between control and deferoxamine pretreatment group. 4. Area at necrosis to area at risk was significantly reduced in deferoxamine pretreatment group compared with control group (P<0.05) The results suggest that deferoxamine infusion prior to coronary artery occlusion has a significant benefit in reducing infarct size in this model.

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a widely used method for providing nutritional support for patients who require prolonged tubal feeding. As survival times of PEG inserted patients increase, PEG related complications are also increasing. For this reason, we decided to review complications related to PEG. MATERIALS AND METHODS: A retrospective review of medical records was conducted for patients who received PEG placement between January 2004 and March 2013 in our hospital. Of the total 331 cases of PEG placement, 131 cases of PEG exchanges were excluded and a total of 200 cases were included in our review. We reviewed the baseline characteristics of all PEG inserted patients and complications related to PEG insertion. RESULTS: Complications related to PEG developed in 45 of 200 patients (22.5%). Peristomal infection occurred in 22 patients (11.0%) and buried bumper syndrome occurred in 10 patients (5.0%). Other complications that occurred in 13 patients were hemorrhage (3.0%), leakage (1.0%), aspiration pneumonia (1.0%), ileus (0.5%), necrotizing fasciitis (0.5%) and gastro-colo-cutaneous fistula (0.5%). The characteristics according to age, gender, procedure place and underlying disease were not different between the complication group and non complication group. The onset time to complication was significantly different between the buried bumper syndrome group and the other complication groups (P=0.035). CONCLUSIONS: Peristomal infection was the most common complication of PEG in our hospital. Late peristomal infection and buried bumper syndrome occurred more often than previous studies. Buried bumper syndrome was more likely to occur in later time compared with the other complications.

STUDY DESIGN: A retrospective study. OBJECTIVES: To evaluate the association between smoking and osteoporotic vertebral fractures (OVFs) in postmenopausal women. SUMMARY OF LITERATURE REVIEW: Several studies have examined the relationship of smoking with hip fractures, but few studies have analyzed the relationship of smoking with spine fractures in women thus far. MATERIALS AND METHODS: This study considered 1255 postmenopausal women aged 50 years and older (enrollment from April 2008 to January 2009) from 62 study sites in a nationwide hospital. The amount of smoking was calculated in pack-years. Further, OVFs were diagnosed using a semi-quantitative method. To analyze the relationship between smoking and OVFs, we used a paired t-test, a χ2-test, and a binary logistic regression analysis. RESULTS: The past history of smoking was 7.2% in the patient group and 4.3% in the control group (p=0.025). The mean pack-years of smoking was 0.34 in the control group and 0.62 in the patient group (p=130). The mean T-score in the lumbar bone mass density (BMD) was –1.64 in the control group and –2.19 in the patient group (p=0.409). Smoking was a risk factor of vertebral fractures in postmenopausal women (odd's ratio=1.68, 95% confidence interval=1.020–2.759, p=0.042) irrespective of the lumbar BMD and the medical treatment for osteoporosis and obesity. CONCLUSIONS: Smoking is a risk factor for osteoporotic vertebral fractures in postmenopausal women independently without regard to lumbar BMD. Therefore, cessation of smoking is important for the prevention of OVFs in postmenopausal women.

Duodenal duplication cyst is a rare anomaly, totaling only 4% to 12% of gastrointestinal duplications, and is usually encountered during infancy or in early childhood. Most are commonly located posterior to the first or second portion of the duodenum. Presenting signs and symptoms include vomiting, decreased oral intake, periumbilical tenderness, abdominal distention, obstructive jaundice, acute pancreatitis, and gastrointestinal bleeding. The traditional treatment of a duodenal duplication cyst has been complete surgical resection, but very few cases of endoscopic treatment have been reported in the literature. Here, we report a case of duodenal duplication cyst that was manifested by a duodenal polyp.

PURPOSE: A recent report introduce a new option for cardiopulmonary resuscitation by using of a continuous descending aortic balloon occlusion. The aim of the present study was to evaluate the effect of balloon occlusion of the descending aorta during cardiopulmonary resuscitation on brain ischemia. METHODS: Twelve rabbits were enrolled in this study. A 4 French Swan-Ganz catheter was advanced through the right femoral artery into the descending aorta. Ventricular fibrillation was induced with an AC current delivered through an electrode catheter advanced into the right ventricle. After 3 minutes of untreated ventricular fibrillation, the rabbits were randomized in two groups: (1) chest compression without balloon occlusion (control group) and (2) chest compression with balloon occlusion of the descending aorta (experimental group). The balloon was inflated for 3 minutes during resuscitation. Defibrillation was attempted at 3 minutes after start of chest compression. At 24 hours after return of spontaneous circulation, brain tissues were fixed in 4% paraformaldehyde and stained with hematoxylin eosin. Then, the ischemic cells in the hippocampal CA1 area were counted. RESULTS: There was significant difference in ischemic neuronal cells between the two groups (control group: 41.8 +/-10.9%, experimental group: 16.8+/-6.8%, p < 0.05). In the experimental group, carotid blood flow was better than it was in the control group during chest compression (control group: 2.4+/-1.0 mL/min, experimental group: 7.6+/-1.9 mL /min, p < 0.05). CONCLUSION: These results suggests that balloon occlusion of the descending aorta during resuscitation decreases brain ischemia in rabbits during cardiac arrest.
