Isolation of Microsporum canis from home environment was carried out for 30 tinea capitis patients infected by M, canis. M. canis was isolated in 84.2-100% of patients caps, mattresses, clothes and pillows and families' clothes. The greatest mean number of M. canis colonies per petri dish was found in the patients pillows and followed by caps, mattresses, outerwear, and underwear. Mean number of M. canis colonies in the clothes of mothers, grandmothers, brothers, sisters and roommates of patients was smaller than that of the M. canis colonies in the clothes of patients but greater than that isolated from the clothes of other family members. Frequency of isolation and mean number of colonies decreased drarnatically after 2 weeks therapy and rarely isolated after 6 weeks therapy. M. canis was isolated in 100% of the house dust of patients. Isolation index was greater in the house dust of patients with concomittant infection of other family members and with lesions of scaly and inflammatory type. M. canis was isolated from cats and goat of patients by the hair brush technique.

A 23-month-old male patient with treated bronchitis underwent a surgery for the repair of bilateral Hutch's diverticulum of bladder under general anesthesia. He treated bronchitis during 2 weeks since 3 weeks before operation. Arriving operating room, he had mild coughing with sputum. During anesthesia, he was well ventilated but endotracheal secretion was profuse. At ABGA of 2 hours after starting anesthesia, severe hypercapnea(PaCO2: 190.2 mmHg) and severe acidosis(PH: 6.746) were checked. Active treatment was done by suction of endotracheal secretion, hyperventilation, PEEP(5~10 cmH2O), increasing fresh gas flow rate(3.6 L/min --> 7 L/min), and administration of sodium bicarbonate, orciprenaline sulfate and methyl- prednisolone. After 3 hours of treatment, ABGA was normalized and symptoms including wheezing were relieved.

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) has come into use and been widely extended because of the low complication rate and less-invasiveness. This article aimed to describe our experience in the treatment of abdominal aortic aneurysm with EVAR. MATERIALS AND METHODS: A retrospective review was conducted for the 22 patients who underwent EVAR in a single hospital December 2001 to June 2009. RESULTS: The mean age of the patients was 68.5+/-7.6 years. There were several risk factors and comorbidities in 20 patients (90.9%). The mean diameter of the aortic aneurysms was 61.2+/-12.9 mm. The mean length, diameter, and angle of the aneurysmal neck were 30.5+/-15.5 mm, 24.0+/-4.5 mm, and 43.9+/-16.0degrees, respectively. The mean follow-up period of the patients was 28.8+/-29.5 months. The 30-day postoperative mortality was none. Seven patients (31.8%) had endoleaks during the hospital stay and three patients (13.6%) had endoleaks during the follow-up period. One patient (4.5%) died due to a ruptured aortic aneurysm. The cumulative patient survival rates were 88.2%, 88.2%, and 70.6% at 1, 3, and 5 years of follow-up, respectively. CONCLUSION: EVAR is currently a safe, feasible procedure for high risk patients with abdominal aortic aneurysm because of low postoperative complication and mortality if patients are selected properly and followed up carefully.

PURPOSE: To evaluate the neuroprotective effects of betaxolol (betaxolol hydrochloride) under hypoxic conditions using retinal ganglion cells (RGC-5) and determine whether heme oxygenase-1 (HO-1) expression exerts cytoprotective effects. METHODS: In this study, cultured RGC-5 cells were incubated with different concentrations of betaxolol hydrochloride (0.1 microM, 1 microM or 5 microM) and with 10 microM zinc protoporphyrin (ZnPP), in a hypoxia incubator (1% O2, 5% CO2, 94% N2) for 48 hours and the cell viability of each group was determined. Additionally, cell viability was measured after RGC-5 cells were incubated with 5 microM of brinzolamide (Azopt(R)), brimonidine tartrate (Alphagan(R)) or travoprost (Travatan(R)). RGC-5 cells were divided into three groups and incubated under three different conditions, normoxia group (20% O2, 5% CO2), hypoxia group (1% O2, 5% CO2) and the group with 5 microM of Betoptic S(R) treated under hypoxic conditions (hypoxia, Betoptic S(R)). After incubation for 4, 8, 12 and 24 hours, HO-1 expression was analyzed using Western blotting. RESULTS: Cell viability significantly increased in RGC-5 cells treated with Betoptic S(R) compared with other antiglaucoma agents. Increased levels of HO-1 expression indicate its relevance in cell viability. Furthermore, increased RGC-5 cell viability by Betoptic S(R) was significantly reduced in the HO-1 inhibitor ZnPP-treated group. CONCLUSIONS: We reaffirmed the known cytoprotective effects of Betoptic S(R) and the results suggests that HO-1 expression exerts cytoprotective effects against hypoxia.

BACKGROUND AND OBJECTIVES: The aims of this study were to evaluate the anatomical features of patients with obstructive sleep apnea syndrome (OSAS) using upper airway computed tomography (CT) in the awake state, and to analyze the correlation between anatomical features and severity of polysomnography (PSG) findings. MATERIALS AND METHODS: Sixty-eight patients presenting with snoring and sleep apnea were included, and upper airway CT in the awake state and PSG were performed in all patients. The average apnea-hypopnea index (AHI) and minimal arterial oxygen saturation (minSaO2) values were calculated. The axial and sagittal images from the level of the nasopharynx to that of the hypopharynx were obtained and measured. The correlations of the anatomical parameters with AHI and minSaO2 were statistically analyzed. RESULTS: The significant parameters correlated with AHI were nasopharynx anterior-posterior (A-P) diameter and transverse diameter, soft palate transverse diameter, uvula length, tongue length, lingual transverse diameter, and hypopharynx A-P diameter & transverse di-ameter. The parameters correlated with minSaO2 were nasopharynx transverse diameter and lingual transverse diameter. Conclusions: Upper airway analysis using CT in awake OSAS patients provides anatomical parameters which correlate with the severity of OSAS. Therefore, upper airway CT in the awake state may be helpful in diagnosing OSAS.

PURPOSE: Radiation pneumonitis and fibrosis are common complications of radiation therapy of the chest. Sixty-six patients with lung cancer were studied to evaluate the radiation injury according to radiation dose (total and estimated single dose), time after completion of radiation, overall treatment time, and combined chemotheraphy and chest surgery. METHODS AND MATERIALS: All 66 patients received fractionated radiotherapy (180 to 300 cGy/day) to the thctax with total 1000 to 6660 cGy encompassing primary site and regional lymphatics. RESULTS: Radiation pneumonitis was developed in 40(60%) of 66 patients. Radiation pneumonitis occurred average 11 weeks after completion of therapy in 14(44%) of 32 patients below 4000 cGy, and 6 weeks in 26 (76%) of 34 patients above 4000 cGy. Radiation pneumonitis occurred more frequently when the estimated! single dose was over 1100 units than below 1100 units. Radiation pneumonitis was more frequent when the overall treatment time was over 30 days than within 30 days. All 10 patients undergone Iobectomy or pneumonectomy developed radiation pneumonitis. CONCLUSION: The incidence of radiation induced lung injury is variably dependant on radiation dose, time, from completion of radiation therapy, overall treatment time, and history of surgery such as Iobectomy or pneumonectomy before radiation therapy.

PURPOSE: To investigate the production of long pentraxin 3 (PTX3) in response to tunicamycin-induced endoplasmic reticulum (ER) stress and its role in ER stress-associated cell death, PTX3 expression was evaluated in the human retinal pigment epithelial cell line, ARPE-19. METHODS: PTX3 production in ARPE-19 cells was analyzed in the absence or presence of tunicamycin treatment by enzyme-linked immunosorbent assay. PTX3 protein and mRNA levels were estimated using western blot analysis and real-time reverse transcription-polymerase chain reaction, respectively. Protein and mRNA levels of CCAAT-enhancer-binding protein homologous protein (CHOP) and ARPE-19 cell viability were measured in the presence of tunicamycin-induced ER stress in control or PTX3 small hairpin RNA (shRNA)-transfected ARPE-19 cells. RESULTS: The protein and mRNA levels of PTX3 were found to be significantly increased by tunicamycin treatment. PTX3 production was significantly decreased in inositol-requiring enzyme 1α shRNA-transfected ARPE-19 cells compared to control shRNA-transfected cells. Furthermore, pretreatment with the NF-κB inhibitor abolished tunicamycin-induced PTX3 production. Decreased cell viability and prolonged protein and mRNA expression of CHOP were observed under tunicamycin-induced ER stress in PTX3 shRNA transfected ARPE-19 cells. CONCLUSIONS: These results suggest that PTX3 production increased in the presence of tunicamycin-induced ER stress. Therefore, PTX3 could be an important protector of ER stress-induced cell death in human retinal pigment epithelial cells. Inositol-requiring enzyme 1α and the NF-κB signaling pathway may serve as potential targets for regulation of PTX3 expression in the retina. Therefore, their role in PTX3 expression needs to be further investigated.

The orbital wall resection with removal of tumor in patient who has malignant tumor in paranasal sinuses or nasal cavity causes enophthalmos, dystopia, or severe facial deformities. The methods of reconstruction of orbital wall have been used skin graft, muscular sling, parietotemporal fascial calvarial bone flap, and free flaps. The parietotemporal fascial calvarial bone flap has been used as a pedicle flap, but it can not be used in reconstruction of medial wall of the orbit because it has a short vascular pedicle. Therefore we designed the galeal-frontalis- pericranial-calvarial bone flap which is a new pedicled bone flap for reconstruction of orbital wall. We used this flap in 2 patients who have orbital wall defect following resection of malignant tumor arising from the nasal cavity or maxilla. The outcome was gratifying in all two patients. We think that this flap is a new useful method in reconstruction of the orbit.

Radiosurgery requires integral procedure where special devices and computer systems are needed for localization, dose planning and treatment. The aim of this work is to verify the overall mechanical accuracy of our LINAC and develop dose calculation algorithm for LINAC radiosurgery. The alignment of treatment machine and the performance testing of the entire system were extensively carried out and the basic data such as percent depth dose, off-axis ratio and output factor were measured. A three dimensional treatment planning system for stereotactic radiosurgery has been developed. We used an IBM personal computer with C programming language (IBM personal system/2, Model 80386, 1BM Co., USA) for calcu1ating the dose distribution. As a result, deviations at isocenter on gantry and table rotation for our treatment machine were acceptable since they were less than 2 mm. According to the phantom experiments, the focusing isocenter were successful by the error of less than 2 mm. Finally, the mechanical accuracy of our three dimensional planning system was confirmed by film dosimetry in sphere phantom.
