BACKGROUND: Wheezing which is defined as a continuous sound with a musical quality is commonly auscultated in patients with chronic obstructive airway diseases. The correlation between wheezing and airway obstruction is unclear. OBJECTIVE: This study was designed to evaluate the relationships among wheezing, severity of airway obstruction, and pulmonary function tests. METHOD: Forty-one subjects were examined by the same observer. Wheezing during normal breathing and maximal forced exhalation, was auscultated respectively. Posterior lung bases were auscultated bilaterally with the seated patient taking repeated inspiratory capacity breaths through an open mouth. To quantify wheezing intensity, a regional score was assigned for each area after a minimum of 3 breaths, according to the following scale: zero, no wheezing heard: one, faint or intermittent wheezes: two, moderate wheezing during every expiration: three, loud wheezing during every expiration. The lung function tests by standard pneumotachograph were performed by skilled technicians. RESULTS: Wheezing was auscultated more in forced exhalation than in normal breathing in patients with asthma and COPD [8/9(88%) vs 1/9(11%), p<0.01 ll/15(73%) vs 1/15(6%), p<0.05)]. Forced expiratory wheezes group (n=25) compared to no wheezes group (n=16) had significantly lower FEVl (75+-5.8% vs 95.6+-6.6%, p<0.05). Compared to no wheezes group, the group with forced expiratory wheezes had lower FEV1 and FEV1/FVC (50.4+- 21.3% vs 81.15+-27.7%, 70.4+-22.4% vs 92.5+-19.3%, respectively, p<0.05). Bronchial asthma compared with COPD tended to have higher wheezing scores (Wheeze scores Bronchial asthma 3.5 vs COPD 2.4, p=0.08). Wheezing scores were correlated to FEV1 (normal breathing: r=-0.35, p<0.05: forced exhalation: r=-0.45, p<0.05), but no differences were found in wheezing incidence according to severity of airway obstruction. CONCLUSION: These findings suggest that wheezing on maximal forced exhalation may be a useful physical indicator for evaluating the severity of airway obstruction.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

Time to antagonism induced by pyridostigmine from different levels of neuromuscular blockade was evaluated in 45 patients anesthetized with nitrous oxide, fentanyl, and vecuronium. Neuromuscular blockade, as monitered by train-of-four count, was antagonized at varing degrees of spontaneous recovery. Train-of-four ratio was used as an index of the ability of the patients to maintain adequate spontaneous ventil'ation, and maximum inspiratory pressure as an index of the ability of the patients to protect their airways against aspiration or obstruction. We measured time from administration of pyridostigmine to train-of-four ratio of 70% indicating the recovery of the ability to maintain adquate spontaneous ventilation, and time to maximum inspiratory pressure of -45 cmH2O indicating the recovery of the ability to protect the patients airways against aspiration or obstruction. For a train-of-four count level of 0-1, reversal time to train-of-four ratio of 70% was 22.73+/-3.00 minutes and that to maximum inspiratory pressure of -45 cmH2O was 30.33+/-2.69 minutes. For a train-of-four count level of 2- 3, reversal time to train-of-four ratio of 70% was 17.33+/-3.18 minutes and that to maximum inspiratory pressure of -45cmH2O was 22.27+/-2.91 minutes. For a train-of-four count level of 4, reversal time to train-of-four ratio of 70% was 8.40+/-3.58 minutes and that to maximum inspiratory pressure of -45 cmH2O was 14.60+/-3.11 minutes. It is concluded that the more shallow is the neuromuscular blockade, the more rapid and the safer is the reversal of neuromuscular blockade, although the dose of reversal drug was determined according to the depth of neuromuscular blockade. Moreover, it should take more than 30 minutes to antagonixe profaund neuromuacular hlock- ade induced by vecuronium to such a degree that not only can the patients maintain adequate spontaneous ventilation, but they can maintain the airways and protect them against aspiration as well.

BACKGROUND: It is important to know the location, number, size and shape of bullae before thoracotomy or VATS bullectomy. Chest X-ray and chest CT may be used but with some limitation. The purpose of this study was to compare the diagnostic value of thoracography with that of chest X-ray in preoperative detection of bullae. Meterial and Method: Thoracography was performed by injection of non-ionic water-soluble dye into pleural space in 22 primary spontaneous pneumothoraces, which underwent thoracotomy or VATS bullectomy. Chest X-ray and thoracography were compared through operative finding. RESULTS: Sensitivity and accuracy of thoracography (75% and 72.7%) were higher than those of chest X-ray (30% and 36.4%). However, specificity of thoracography (50%) was lower than that of chest X-ray (100%). There were no complications during or after thoracography. CONCLUSION: Thoracography is a safer and more useful method for preoperative detection of bullae when compared with chest X-ray.

Eosinophilic colitis is a chronic inflammatory bowel condition of unknown etiology and a rare subtype of eosinophilic gastrointestinal diseases. It is characterized by gastrointestinal symptoms and increased eosinophil numbers in the intestinal mucosa and absence of other potential causes of gastrointestinal eosinophilia. The clinical presentation is varied and depends on the involved layer of the large intestine. There are no confirmatory laboratory tests, and the morphologic evaluation of biopsies or surgical specimens is required to confirm the diagnosis. A 65-year-old man presented with an 8 day duration of bloody diarrhea and lower abdominal pain. The patient was diagnosed with eosinophilic colitis by histopathological evaluation of biopsies and was further categorized as a nonatopic variant associated with non-IgE-mediated reaction. The patient was successfully treated with systemic corticosteroid for 2 weeks. On follow-up after 9 months, the patient remained well without relapse or new lesions.

The authorsinvestigated the effects of UV-B and amniotic membrane graft about PRK induced inflammatory cell infiltration into corneal stroma, lipid peroxidation and keratocyte apoptosis. Total 20 white rabbits were divided into 5 groups; 1)mechanical epithelial removal, 2)epithelial removal and UV-B irradiation, 3)PRK only, 4) PRK and UV-B irradiation, 5)Amniotic membrane graft after PRK and UV-B irradiation. All corneas were harvested after 24hrs. H & E stain for PMNs infiltration, MDA immunohistochemical stain for lipid peroxidation and TUNEL stain for keratocyte apoptosis were performed. UV-B had little effect on infiltration of inflammatory cell into corneal stroma, lipid peroxidation and keratocyte apoptosis. Amniotic membrane suppressed infiltration of PMNs into corneal stroma, lipid peroxidation and keratocyte apoptosis. Environmental UV-B exposure should not be avoided after PRK. Amniotic membrane graft is beneficial to reduce keratocyte apoptosis and related corneal haze.

Along with traditional goal of 'straightening teeth', today's orthodontics put more and more emphasis on facial esthetics. Naturally, the importance of soft tissue, which dictates one's facial form, is noticed. There have been many cephalometric studies on growth of hard tissue; however, only a few on that of soft tissue. In Korea, various methods of sampling, measuring and analysing were used to study soft tissue changes, and yet, soft tissue changes along with process of normal growth have not been studied. The author carried out this study as a part of semi-longitudinal study on craniofacial growth and development of Korean children from ages of six to seventeen. 409 boys and 436 girls who'd had no systemic disease for the last three years and shown normal developmental and occlusal status were chosen as subjects. Cephalometric X -rays were taken of each subject, and facial form, lip position & form, nose form, and lip thickness were measured, Mean values and standard deviations were calculated according to age and gender, and figures and tables were drawn accordingly. The following results were obtained: 1. In respect to facial form, boys showed growth for longer period compared to girls. Also, lower face showed higher growth rate than upper face. 2. There was not much change in thickness of upper and lower lips with age; however , they appeared more prominent compared to caucasian children. 3. Nose grew horizontally with age. 4. Horizontal thickness of lower face increased with age, and upper lip thickness at nose base[A-Sn(FH)] showed more growth than anywhere else.

Type 2 diabetes mellitus (T2DM) is a complex endocrine and metabolic disorder, and a major public health problem that is rapidly increasing in prevalence. Although a wide range of pharmacotherapies for glycemic control is now available, management of T2DM remains complex and challenging. The kidneys contribute immensely to glucose homeostasis by reabsorbing glucose from the glomerular filtrate. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, a new class of antidiabetic agents that inhibit glucose absorption from the kidney independent of insulin, offer a unique opportunity to improve the outcomes of patients with T2DM. In this review, we provide an overview of two globally-approved SGLT2 inhibitors, dapagliflozin and canagliflozin, and discuss their effects and safety. This information will help clinicians to decide whether these drugs will benefit their patients.

OBJECTIVES: Outpatient treatment orders refer to a mandatory social program in which mentally ill persons are ordered by the court to participate in specified outpatient treatment programs. This study aimed to investigate the factors that affect outpatient treatment orders and adherence to outpatient treatment in mental health patients. METHODS: A survey on outpatient treatment orders and adherence to outpatient treatment was conducted on 60 psychiatrists between October and November 2016. The questionnaire items were drafted based on a literature review, and they were then evaluated by 3 psychiatrists and 1 law school professor before being finalized. Answers from the respondents were analyzed using descriptive statistics, and the median, maximum, and minimum values of the effectiveness scores of outpatient treatment orders were calculated. RESULTS: Among the 60 psychiatrists, 45(75.0%) were aware of outpatient treatment orders; however, only 2 out of the 45(4.0%) had actually used the program in the last 12 months. The subjective effectiveness was very low, with only 40 points out of 100. Furthermore, of the readmitted patients, 37.7% had received continued outpatient treatment, whereas 53.1% chose to quit the outpatient treatment programs, meaning that the number of dropouts was higher. Among the discharged patients, approximately two-thirds were receiving continued treatment. With regard to follow-up for dropouts, majority of the responses were either “Not taking any action”(n=27) or “Not following up”(n=15). Only two respondents answered “Contact the community mental health promotion center,” meaning that this response was very rare. Meanwhile, when asked about efficient measures to be implemented for dropouts, a vast majority of the respondents(n=30) selected the answer “Work with the community mental health promotion center.” CONCLUSIONS: The outpatient treatment orders currently being administered were found to be ineffective, and the associated adherence to outpatient treatment was also found to be extremely poor. Hence, the effectiveness of the therapeutic interventions could benefit from institutional as well as administrative improvements. Community mental health promotion centers are expected to have an important role in the future.
