BACKGROUND: The wound healing process is impaired or delayed in aged patients. The development of a new wound healing model is needed. Nerve growth factor (NGF) plays a special role in wound healing because NGF is expressed only in proliferating tissues such as wounds. OBJECTIVE: The aim of our study was to develop a wound healing model using a 3-dimensional culture system, raft culture, by comparing the level of NGF expression according to the wound stage after an artificial wound was made to the raft samples. We tried to specifically localize the site of NGF expression both in mRNA and protein level. METHODS: Raft culture using normal human keratinocytes was done and a 2 mm slit wound was made in the center of the raft samples. Raft samples of no wound, 4 d, 7 d, and 9 d after wounding were prepared. In situ RT-PCR and immunohistochemistry were performed to detect and localize NGF expression after making wounds and the addition of substance P (SP). RESULTS: We failed to localize NGF mRNA expression in raft samples by in situ RT-PCR. Immunohistochemistry showed NGF staining throughout the epidermis although a little more dense staining was found in the basal layer. NGF(+) cells tended to increase until 7 d after wounding, but there were no significant differences according to the wounding days. There was `a tendency that the SP(+) group showed more NGF(+) cells than the SP(-) group, but there were no statistical differences. CONCLUSION: We think that our in vitro raft wound model using NGF expression could be used, at least in part, as an objective indicator for wound healing. In our raft model lacking nerve, NGF may not be suitable for representing wound healing process because this model can not reflect the interaction between the skin and the nervous system. Expression of growth factors or cytokines other than NGF need to be applied to our raft culture system.

Chronic mucocutaneous randidiasis is a clinical syndrome characte ized by chronic and reccurent superficial candidal infection of the skin, mucous membranes, and nails. This syndrome is frequently associated with immune deficiency or endocrinopathy, especially hypopar; thyroidism. We report a case of chrcinic mucocutaneous candidiasis associated with hypoparathyroidism in a 8- year-old girl.

BACKGROUND: Incretin hormone levels as a predictor of type 2 diabetes mellitus have not been fully investigated. Therefore, we measured incretin hormone levels to examine the relationship between circulating incretin hormones, diabetes, and future diabetes development in this study. METHODS: A nested case-control study was conducted in a Korean cohort. The study included the following two groups: the control group (n=149), the incident diabetes group (n=65). Fasting total glucagon-like peptide-1 (GLP-1) and total glucose-dependent insulinotropic peptide (GIP) levels were measured and compared between these groups. RESULTS: Fasting total GIP levels were higher in the incident diabetes group than in the control group (32.64±22.68 pmol/L vs. 25.54±18.37 pmol/L, P=0.034). There was no statistically significant difference in fasting total GLP-1 levels between groups (1.14±1.43 pmol/L vs. 1.39±2.13 pmol/L, P=0.199). In multivariate analysis, fasting total GIP levels were associated with an increased risk of diabetes (odds ratio, 1.005; P=0.012) independent of other risk factors. CONCLUSION: Fasting total GIP levels may be a risk factor for the development of type 2 diabetes mellitus. This association persisted even after adjusting for other metabolic parameters such as elevated fasting glucose, hemoglobin A1c, and obesity in the pre-diabetic period.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential far abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. the onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-l0g. We describe an 23-year-old woman with pulmonary edema and cardiac arrest after ingestion of 18 grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and hemoperfusion. We report a case with literature review.

BACKGROUND: Metabolic syndrome (MetS) is a condition characterized by a cluster of metabolic disorders and is associated with increased risk of cardiovascular disease (CVD). This study analyzed data from the Korean Health and Genome Study to examine the impact of MetS on CVD. METHODS: A total of 8,898 subjects (4,241 males and 4,657 females), 40 to 69 years of age, were enrolled and evaluated for the development of new onset CVD from 2001 to 2012 (median 8.1 years of follow-up). RESULTS: The prevalence of MetS at baseline was 22.0% (932/4,241) and 29.7% (1,383/4,657) in males and females, respectively. MetS was associated with increased risk of coronary heart disease (CHD; hazard ratio [HR], 1.818; 95% confidence interval [CI], 1.312 to 2.520 in males; HR, 1.789; 95% CI, 1.332 to 2.404 in females) and CVD (HR, 1.689; 95% CI, 1.295 to 2.204 in males; HR, 1.686; 95% CI, 1.007 to 2.192 in females). Specifically, MetS was associated with risk of future stroke in females only (HR, 1.486; 95% CI, 1.007 to 2.192). Among MetS components, abdominal obesity and hypertension were independent predictors of both CHD and CVD. In addition, a higher number of MetS components correlated with higher CVD risk. CONCLUSION: MetS is a significant risk factor for the development of CVD although its impact varies between sexes.

STUDY DESIGN: Infectious spondylitis patients were classified according to their cause in pyogenic and tuberculous and compared by each. SUMMARY OF LITERATURE REVIEW: Tuberculous spondylitis shows chronic clinical course and disc space sparing with much pus formation in radiologic finding compared to pyogenic spondylits. PURPOSE: To compare pyogenic and tuberculous spondylitis in clinical, radiological, pathological difference for appropriate management of infectious spondylitis. MATERIALS AND METHODS: We reviewed sixty two cases of infectious spondylitis confirmed by culture and pathologic findings of specimens which obtained by surgical method at the orthopaedic department of the Dong-A university hospital between June 1990 and November 1998. RESULTS: There were 18 cases of pyogenic and 44 cases of tuberculous spondylitis, and combined infection case was absent. Average period between beginning of symptom and diagnosis was 6.4 months in pyogenic spondylitis(4-11 months), 3.9 months in tuberculous spondylitis(3-39 months). The average number of affected vertebra was 2.3 in pyogenic spondylitis and 3.9 in tuberculous spondylitis. 6 cases of pyogenic spondylitis(33%) showed high fever(above 38degree C) which not presented in tuberculous spondylitis. We could not find considerable difference in leukocyte count, ESR, CRP level and simple radiologic finding, MRI finding between pyogenic and tuberculous spondylitis. CONCLUSIONS: In our study, most pyogenic spondylitis shows chronic and inactive feature, so clinical, radiological, laboratory findings are not appropriate guide to differentiate between pyogenic and tuberculous spondylitis. Culture growth of infecting agent and histologic examination are reliable and essential diagnostic method for pyogenic and tuberculous spondylitis.

Hepatocyte growth factor (HGF) is a potent mitogen and promoter of proliferation of insulin producing beta cells of pancreatic islets. To study the role of HGF, an adenoviral vector carrying the human HGF (Ad.hHGF) gene was transfected into the streptozotocin-induced diabetic mice and evaluated the effect on the blood glucose metabolism and the insulin-secreting beta cells of pancreatic islets. Ad.hHGF gene transfection resulted in amelioration of hyperglycemia and prolongation of survival period in the diabetic mice. Concomitantly adenoviral- mediated hHGF gene therapy slightly increased serum insulin concentration and the expression of insulin in the pancreatic islet. Although the proliferation of beta-cell mass was not noticeable, the beneficial effect of HGF is significant to an almost deteriorated pancreatic islets. Taken together, these data suggest that the Ad.hHGF gene therapy into diabetic mice may prevent the further destruction and present as a beneficial remedy for type 1 diabetic patients.

BACKGROUND: There were several studies for the incidence of gastroesophageal reflux associated with the laryngeal mask airway(LMA), but the results of those studies were much different much different from one another. The aim of this study was to compare the incidence of gastroesophageal reflux and regurgitation of gastric contents between the LMA and the endotracheal tube(ETT). METHOD: Ninety patients scheduled for elective orthopedic surgery with a standardized general anesthetic technique were randomly allocated to receive either a LMA(n-49) or a ETT(n=41) for airway management. The esophageal manometry was carried out for the exclusion of esophageal motility disorders and the 24-hour ambulatory pH metry was done from one day before the operation. A methylene blue(50mg) capsule was swallowed just before the induction and the simultaneous recordings of pH were maintained during anesthesia. At the end of anesthesia, the episodes of regurgitation of gastric contents above hypopharynx were analyzed by the pharyngeal blue staining and the pH metric data were analyzed for the detection of gastroesophageal relux episodes during anesthesia. RESULTS: There was no significant difference in the incidence of gastroesophageal relux(pH< or =4) between two groups; only two patients in LMA and three patients in ETT had reflux episodes during the removal or arousal phase. There was no episode of the pharyngeal blue staining in both group. All of the gastroesophageal reflux patients in both group developed a cough or straining during those phases. There was no clinical evidence of aspiration of gastric contents in both group. CONCLUSION: In comparison with ETT, use of LMA does not appear to increase the incidence of gastroesophageal reflux and regurgitation above hypophryngeal level in positive pressure ventilating patients during long surgical procedures. Therefore, the risk of aspiration in LMA will not be much more than ETT.

OBJECTIVE: To investigate the prevalence of chronic obstructive pulmonary disease (COPD) in stroke patients, and to assess the difference in swallowing function between stroke patients with COPD (COPD group) and stroke patients without COPD (control group). METHODS: The subjects included 103 stroke patients. They underwent the pulmonary function test and were assigned to either the COPD group or the control group. Their penetration-aspiration scale (PAS) scores and functional dysphagia scale scores were compared by performing a videofluoroscopic swallowing study. The intergroup differences in lip closure, bolus formation, mastication, and the oral transit time, laryngeal elevation, cricopharyngeal dysfunction, oronasal regurgitation, residue in pyriform sinus and vallecula, pharyngeal transit time, aspiration, and esophageal relaxation were also compared. RESULTS: Thirty patients were diagnosed with COPD. The COPD group showed statistically higher PAS scores (4.67+/-2.15) compared to the control group (2.89+/-1.71). Moreover, aspiration occurred more frequently in the COPD group with statistical significance (p<0.05). The COPD group also showed higher occurrence of cricopharyngeal dysfunction, albeit without statistical significance. CONCLUSION: This study shows that a considerable number of stroke patients had COPD, and stroke patients with COPD had higher risk of aspiration than stroke patients without COPD.

Methamphetamine is one of the most popular abuse drug in the South Korea. Intracranial hemorrhage or ischemic stroke have been well known as one of the complications with methamphetamine abuse. We experienced two cases with cerebral vasculopathy which had developed after intravenous use of methamphetamine. The first patient was a previously healthy 20-year-old woman, who was admitted because of drowsy mentality with left hemiparesis and dysarthria. The second patient was a 24-year-old man who was admitted because of seizure and left extremity weakness. They reported several intravenous administration of methamphetamine during previous months. In both case, brain CT showed cerebral infarction compatible with vascular territories. And also, carotid angiographys demonstrated that multiple intracranial vessels were involved with narrowing and stenotic nature, consisting with vasculitis in the both cases.
