Background: Otomycosis is a fungal infection that comprises 7~10% of outer ear infections. Although the occurrence is higher in humid climates, relatively few studies have investigated otomycosis occurrences in humid environments. While recurrent chronic otitis media discharge in the ear creates a milieu in which otomycosis is likely to occur, investigations of otomycosis co-occurring with chronic otitis media have been rare. Objective: To examine the characteristics of patients with otomycosis co-occurring with chronic otitis media and identify causative fungi. Methods: The study included 60 patients with chronic otitis media who presented typical otomycosis findings in the outer ear canal and the presence of fungi. Patients were treated in the department of otolaryngology, Daegu Catholic University Medical Center, between July 2011 and June 2018. Results: The mean patient age was 57.77 years, and our study included 20 men and 40 women (p=0.010). The lesion was on the right in 39 patients and on the left in 21 (p=0.020). Ear discharge was the most common chief complaint at diagnosis. Of the 54 patients over age 19, 10 had diabetes (18.5%). Aspergillus was causative in 29 patients and Candida in 31. Aspergillus niger was identified in 15 patients, Aspergillus sp. in 14, Candida parapsilosis in 12, Candida sp. in six, and Candida albicans in five. Conclusion: Otomycosis and chronic otitis media co-occurrences increase with age. The Aspergillus and Candida genera were similar in proportion. A. niger was the most common Aspergillus species, while C. parapsilosis was the most common Candida.
The purpose of this study was to analyze the results from statistical process control (SPC) to recommend upper and lower control limits for planning parameters based on delivery quality assurance (DQA) results and establish our institutional guidelines regarding planning parameters for helical tomotherapy (HT). A total of 53 brain, 41 head and neck (H & N), and 51 pelvis cases who had passing or failing DQA measurements were selected. The absolute point dose difference (DD) and the global gamma passing rate (GPR) for all patients were analyzed. Control charts were used to evaluate upper and lower control limits (UCL and LCL) for all assessed treatment planning parameters. Treatment planning parameters were analyzed to provide its range for DQA pass cases. We confirmed that the probability of DQA failure was higher when the proportion of leaf open time (LOT) below 100 ms was greater than 30%. LOT and gantry period (GP) were significant predictor for DQA failure using the SPC method. We investigated the availability of the SPC statistic method to establish the local planning guideline based on DQA results for HT system. The guideline of each planning parameter in HT may assist in the prediction of DQA failure using the SPC statistic method in the future.

When planning pancreaticoduodenectomy for pancreatic head cancer, the prevalence of anatomical variation of the proximal jejunal vein (PJV), the associated short-term surgical outcomes, and the level of PJV convergence to the superior mesenteric vein must be carefully analyzed from both technical and oncological points of view. The prevalence of the first jejunal trunk (FJT) and PJV located ventral to the superior mesenteric artery is 58%-88% and 13%-37%, respectively. Patients with the FJT had a larger amount of intraoperative bleeding and a higher proportion of patients requiring transfusions compared to those without a common trunk. The risk of transfusion was higher in patients with ventral PJV compared to those with dorsal PJV. Although less frequent, sacrificing the FJT can result in fatal venous congestion of the jejunum. Therefore, a well-planned approach for pancreaticoduodenectomy, based on preoperative evaluation of anatomical variation in the PJV, may help reduce intraoperative bleeding and postoperative morbidity. Additionally, the importance of invasion into the PJVs should be revisited in terms of resectability and oncological clearance.

The chemical components, lipid class, and fatty acid composition of muscle from male and female common squid, Todarodes pacificus, were examined to evaluate the potential utilization of muscle from fin, head, arms, and tentacles, which consumers usually like less than the mantle. The mantle was found to constitute 47-49% of the total muscle and the proportion was slightly higher in females than in males. For the remaining 51-53% of the muscle, the only gender difference was that the arms of males contained approximately 3% more muscle than those of females (P<0.05). The protein content was higher in the mantle, arms, and tentacles than in the fin and head in both males and females (P<0.05), and was slightly higher in males (15.7-20.7%) than in females (15.1-19.2%). By contrast, the lipid content was slightly higher in females (1.82-2.54%) than in males (1.01-2.37%), and the fins in both males and females contained the most lipids (2.37-2.54%) of all muscle. The prominent lipid classes in the muscles were free sterol (males 81.5-91.9% vs. females 84.9-91.8% for the non-polar lipid content), phosphatidylcholine (PC, males 59.3-62.4% vs. females 49.2-57.8% for the phospholipid content) and phosphatidylethanolamine (PE, males 22.0-28.8% vs. females 25.6-33.8% for the phospholipid content). The percentage of PC was approximately 5-10% higher in males (P<0.05), especially in the fin, while that of PE was approximately 3-5% higher in female (P<0.05), especially in the head. All of the squid muscle contained 52.1-54.9% of n-3 polyunsaturated fatty acids (PUFA), such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Males contained slightly more DHA, whereas female contained more EPA. The total percentage of n-3 PUFA differed little among muscles within the same gender.

Objective: To compare the clinical and radiological features of various etiologies of chronic diffuse lacrimal gland enlargement. Materials and Methods: We retrospectively reviewed 91 consecutive patients who underwent surgical biopsy for chronic diffuse lacrimal gland enlargement and were diagnosed with non-specific dacryoadenitis (DA) (n = 42), immunoglobulin G4-related dacryoadenitis (IgG4-RD) (n = 33), and lymphoma (n = 16). Data on patient demographics, clinical presentation, and CT imaging findings (n = 73) and MRI (n = 43) were collected. The following radiologic features of lacrimal gland enlargement were evaluated: size, unilaterality, wedge sign, angle with the orbital wall, heterogeneity, signal intensity, degree of enhancement, patterns of dynamic contrast-enhanced, and apparent diffusion coefficient value. Radiological features outside the lacrimal glands, such as extra-lacrimal orbital involvement and extra-orbital head and neck involvement, were also evaluated. The clinical and radiological findings were compared among the three diseases. Results: Compared to the DA and IgG4-RD groups, the lymphoma group was significantly older (mean 59.9 vs. 46.0 and 49.4 years, respectively; p = 0.001) and had a higher frequency of unilateral involvement (62.5% vs. 31.0% and 15.2%, respectively; p = 0.004). Compared to the IgG4-RD and lymphoma groups, the DA group had significantly smaller lacrimal glands (2.3 vs. 2.8 and 3.3 cm, respectively; p < 0.001) and a lower proportion of cases with a wedge sign (54.8% vs. 84.8% and 87.5%, respectively; p = 0.005). The IgG4-RD group showed more frequent involvement of the extra-orbital head and neck structures, including the infraorbital nerve (36.4%), paranasal sinus (72.7%), and salivary gland (58.6%) compared to the DA and lymphoma groups (4.8%-28.6%) (all p < 0.005). Conclusion: Patient age, unilaterality, lacrimal gland size, wedge sign, and extra-orbital head and neck involvement differed significantly different between lymphoma, DA, and IgG4-RD. Our results will be useful for the differential diagnosis and proper management of chronic lacrimal gland enlargement.
The author has conducted survey on the status of physical growth and morbidity of the children for christian children's fund programme, as a means of collecting basic data for the anticipated establishment of a health planning. A total 345 children aged 9 to 16 underwent C.C.F. programme while as a control, a total of 480 children of same ages from the middle-class school children in Jeonju area was also studied. As results of survey conducted for a period of one month (form July 1 to 31, 1974) on a total 429 children in 347 households living in Jeonju area. I. Socio-economic background 1. By educational status of the children, 39.9 per cent of the total children was attending at primary school, 33.8 per cent in middle school and 15.6 per cent in high school. 2. The greatest proportion or 28.8 per cent of the household head were engaged in labor, 17.9 per cent in peddler and 13.2 per cent in retail. 3. As for the living standard of the households, low class constitued 90.1 per cent, middle and high classes only 9.9 per cent. 4. 39.5 per cent of the households had their own house, 39.1 per cent lived in rent deposit house or rooms and 14.6 per cent in monthly rented house and rooms. II. Physical growth and nutritional status 1. The growth of children for C.C.F. programme in terms of height was found to be slightly smaller than the school children. The ages frm 9 to 16 corespond to the 'secondary growth and replenishment period and this period was regarded to be the one most affected by environmental and nutritional factors of all the other periods of growth and developmet. 2. The body weight of the children for C.C.F. presented a quite different pattern from that of the school children. The above findings appeared thin-and-long stature from the famillies with higher living standard while those from the household with low standard of living had a short-and-plump one. 3. According to the values of Rohrer's index, the children of C.C.F carried a higher degree of 'replenishment' than the children in Jeonju area and adolesecence comes later for the girls under C.C.F. programme. III. Morbidity 1. The monthly prevalence rate was 110.0 per thousand persons for the children under C.C.F. programme. 2. The total number of case was classified by timing of the incidence as follws. 40.0 per cent was constituted by diseases carried over from tile previous month and 60.0 per cent by new incidences. 3. The diseases were broken down by W.H.O. disease classification into the greatest proportion or 39.1 per thousand person constituted by disease of the digestive system.

The purpose of this study is to provide basic data for injury prevention measures through the risk factors of injury occurrence by comprehending injury characteristics of the trauma patients visiting a regional emergency medical center according to distribution based on external causes and injury severity score. This study was analyzed using SPSS-Window(ver. 20.1) for 2585 trauma patients who visited a regional emergency medical center and the research period is for four months from 1st of September, 2019 to 31th of December, 2019. The following were the results of the research. First, it is shown from the analyzed data that the proportion of males (61.3%) is greater than that of females (38.7%) and the group aged from 20 to 50 had a significantly higher occurrence rate of injury but in terms of injury severity, 50 takes up the great proportion(P<.001). Second, roads and traffic areas (35.1%) were the highest in the place of occurrence of injury(P<.001). Third, the time of injury occurrence was as high as 12-18 hours(35.8%)(P<.001). Fourth, the injury part was highest in the head and face (55.4%)(P<.001). Fifth, the type of injury was higher in open wounds (31.2%)(P<.001). Therefore, it is required to establish detailed injury prevention policies according to the characteristics of injury severity.

Objectives. The current study aims to determine the correlation between nutritional status upon presentation and disease severity, as well as treatment and survival outcomes. Methods. Patients who were diagnosed with deep neck infection, underwent at least one surgical drainage/debridement, and had more than 1 week of hospitalization at a tertiary medical center from 2007 to 2015 were retrospectively included. Thereafter, initial serum albumin, C-reactive protein (CRP), and body mass index (BMI) were reviewed. Results. A total of 135 patients were included in the final analysis. Accordingly, the proportion of patients with simultaneous mediastinitis (21.0%), necrotizing fasciitis (12.9%), disease extent >1 cervical level (72.6%), mean CRP (22.4 mg/dL), mean length of hospitalization (25.0 days), and mean 1-week follow-up CRP (7.2 mg/dL) was significantly higher in the hypoalbuminemia group (initial serum albumin <3.0 g/dL) than in the normoalbuminemia group (all P<0.05). No significant correlations had been observed according to BMI status. After adjusting for age and Charlson comorbidity index, odds ratios for the following outcomes were calculated in patients initially presenting with hypoalbuminemia: simultaneous mediastinitis (3.07), necrotizing fasciitis (7.89), disease extent >1 cervical level (2.12), initial serum CRP over 20 mg/dL (3.79), hospitalization of more than 14 days (4.10), 1-week follow-up CRP over 5 mg/dL (3.78), and increased duration for an over 50% decrease in initial CRP (2.70) (all P<0.05). Although intravascular albumin replenishment decreased the proportion of patients with hypoalbuminemia after 2 weeks (P<0.05), it did not significantly predict better treatment outcomes. Conclusion. Among the markers reflecting an individual's nutritional state, an initial serum albumin of less than 3.0 g/dL was an independent serologic marker predicting increased disease severity and complications in patients with deep neck infection.
Up-front irradiation technique as 3-dimensional conformation, or intensity modulation has kept large proportion of brain tumors from being complicated with acute radiation reactions in the normal tissue during or shortly after radiotherapy. For years, we've cannot help but counting on 2-D vertex beam technique to reduce acute reactions in the brain tumor patients because we're not equipped with 3-dimensional planning system. We analyzed its advantages and limitations in the clinical application. From 1998 to 2001, vertex or oblique vertex beams were applied to 35 patients with primary brain tumor and 25 among them were eligible for this analysis. Vertex(V) plans were optimized on the reconstructed coronal planes. As the control, we took the bilateral opposed techniques(BL) otherwise being applied. We compared the volumes included in 105% to 50% isodose lines of each plan. We also measured the radiation dose at various extracranial sites with TLD. With vertex techniques, we reduced the irradiated volumes of contralateral hemisphere and prevented middle ear effusion at contralateral side. But the low dose volume increased outside 100%; the ratio of V to BL in irradiated volume included in 100%, 80%, 50% was 0.55+/-0.10, 0.61+/-0.10, and 1.22+/-0.21, respectively. The hot area within 100% isodose line almost disappeared with vertex plan; the ratio of V to BL in irradiated volume included in 103%, 105%, 108% was 0.14+/-0.14, 0.05./-0.17, 0.00, respectively. The dose distribution within 100% isodose line became more homogeneous; the ratio of volume included in 103% and 105% to 100% was 0.62+/-0.14 and 0.26+/-0.16 in BL whereas was 0.16+/-0.16 and 0.02+/-0.04 in V. With the vertex techniques, extracranial dose increased up to $1{\sim}3%$ of maximum dose in the head and neck region except submandibular area where dose ranged 1 to 21%. From this data, vertex beam technique was quite effective in reduction of unnecessary irradiation to the contralateral hemispheres, integral dose, obtaining dose homogeneity in the clinical target. But it was associated with volume increment of low dose area in the brain and irradiation toward the head and neck region otherwise being not irradiated at all. Thus, this 2-D vertex technique can be a useful quasi-conformal method before getting 3-D apparatus.
Background and Objectives : Distinguishing benign from malignant lesion in thyroid noddex is important but clinically difficult. FNAB is the first investigation of choice. However, cytologic results are often indeterminable. In those cases, additional molecular biologic tests are helpful. If serologic tests are available to predict malignancy, it can be useful to fortify accurate diagnosis. We analyzed whether TSH or FreeT4 level could be used as a predictor of malignancy. Materials and Methods : From January 2008 to March 2009, 540 patients received one of thyroidectomy in a single center. We only included 167 patients from 18 to 65 years old without cardiopulmonary or renal disorders. All the patients were in euthyroid state and took no medications, which affect the thyroid function. We reviewed charts retrospectively to find out differences in TSH level and FreeT4 level between the benign and malignant groups. Results : In this study, all the patients with malignancy had the papillary cancer. In benign group, average TSH level came out to be 1.48mU/L, whereas the average TSH level of malignant group was 1.98 mU/L. Moreover, the higher the cancer stage was, the higher the TSH level was. Although we have adjusted factors that can affect TSH level(age, sex, race, goiter type), we still received the same result. The risk of malignant cancer increased in proportion with TSH level within the normal range. In free T4 level, there was no difference between benign and malignant group. Conclusion : We propose that TSH level can play a role as one of the predictors for thyroid cancer. However, there is limitation because all the patients with malignancy in this study have papillary cancer. Thus, we can apply this result only in papillary cancer, and we need more study for other types of thyroid cancer.
