A statistical study of soldiers who visited the outpatient ciepartment of the Capital Armed Forces General Fiospital from 1987 to 1989 was performed. The results were as follows : 1. The total number of outpatients was 9969 with peak clinic visits in June(11.2%) and the lowest number of clinic visits in February(6.4% ). 2. The most frequent age was 22 years(20.7% ). Soldiers between 19 and 24 years old comprised 68.1% of total patients. 3. By rank 69.3% of the outpatients were private', 16.0% sergeant and 14,4% officers. 4. The most common dermatoses were dermatophytosis, contact dermatitis, scabies, acne, seborrheic dermatosis, urticaria, alopecia, condyloma acuminatum, verruca, folliculitis, psoriasis, insect bite reactions, pityriasis rosea, herpes zoster and corns. 5. Frequent diseases, which occured during summer season, included dermatophytosis, contact dermatitis and inser,t bites. The incidence of scabies, pityriasis prsea was increased during winter and that of psoriasis was increased during spring.

Purpose:
This study aimed to explore the knowledge and performance of sleep hygiene among nurses with shift work schedules and examine the influence on sleep disturbance.
Methods:
A total of 199 shift-work nurses from a tertiary hospital were included in the study. To examine the knowledge and performance of sleep hygiene, the participants were asked to respond to a self-reported survey. To assess sleep disturbance, the General Sleep Disturbance Scale was used. Descriptive statistics and multiple linear regression were applied using the SPSS/WIN 21.0 program to analyze the data.
Results:
Both the knowledge and performance of sleep hygiene among nurses with shift work schedules were measured at a moderate level. Nurses’ knowledge and the performance of sleep hygiene was not significantly associated with sleep disturbance, whereas age, experience with shift-working, and perceived health status were significantly associated.
Conclusion
Strategies for providing more accurate information and motivating better sleep hygiene would help to enhance sleep hygiene in nurses with shift work schedules. Further studies examining the association of knowledge and the performance of sleep hygiene with sleep disturbances in nurses with shift work schedules are needed.

PURPOSE: The diagnosis-related group (DRG) system has been adapted to reduce overall medical costs by grouping and classifying relatively homogenous patients based on similar resource consumption patterns in the treatment. However, despite its wide range of disease manifestation from early inflammation to severe peritonitis, acute appendicitis is included in the DRG system. Responding to a need to assess the DRG system for patients diagnosed with appendicitis, this study evaluates the efficacy of the current DRG system applied to a broad spectrum of the patients with appendicitis undergoing laparoscopic appendectomy. METHODS: A retrospective review was conducted of the patients who underwent laparoscopic appendectomy. Based on the DRG codes' classification, the patients were analyzed for the amount of DRG reimbursement and the total in-patient cost in relation to the time sequence of the disease onset. Statistical analysis was performed to find factors correlated with the DRG reimbursement and total in-patient cost. RESULTS: Findings indicate that, as the symptom duration becomes prolonged, the CRP level and the use of peritoneal drainage increased. Patients with a symptom duration greater than 24 hours required approximately 5 days of hospital stay, 0.5 day longer in the length of hospital stay than that of patients with less than 12 hours of the onset time. As expected, the amount of DRG reimbursement and the total in-patient cost accumulated as the symptom duration increased. CONCLUSION: The current DRG reimbursement system for the patients undergoing laparoscopic appendectomy recompenses a broad spectrum of patients diagnosed with appendicitis effectively.

Angiodysplasia is an important vascular lesion of the gastointestinal tract , located at the site of ectasia of intestinal submucosal veins and overlying mucosal capillaries. It is a major cause of morbidity from gastrointestinal bleeding in old age, but rather rare in children. Its cause is still unknown, though is mostly considered to be acquired as a result of a degenerative process associated with aging. We experienced a case of colonic angiodysplasia in 14-year old boy, diagnosed by colonoscopy. The patient had a history of repeated hematochezia for a year. This report summarized our case and reviewed the literature.

In 2023, an 81-year-old woman requested a preliminary red blood cell transfusion during pancreatic cancer surgery, and antibody screening was performed using automated blood typing equipment. The antibody screening test results were negative when plasma was used as the sample but positive when the serum was used instead. The 4℃ test was positive when using the enzyme method but negative at warm temperatures. An unknown antibody was identified using a commercial antibody identification test (Bio-Rad, CA, USA). A clinically insignificant cold antibody was detected only in the serum samples, and the negative blood was ultimately released following the third stage of cross-matching using anti-human globulin.

Background:
The cytologic diagnosis of poorly differentiated thyroid carcinoma (PDTC) is difficult because it lacks salient cytologic findings and shares cytologic features with more commonly encountered neoplasms. Due to diverse cytologic findings and paucicellularity of PDTC, standardization of cytologic diagnostic criteria is limited. The purpose of this study is to investigate and recognize diverse thyroid findings of fine needle aspiration (FNA) cytology and frozen smear cytology in diagnosis of this rare but aggressive carcinoma.
Methods:
The present study included six cases of FNA cytology and frozen smears of histologically diagnosed PDTCs.
Results:
PDTC showed cytologic overlap with well-differentiated thyroid carcinomas (WDTCs). Five of six cases showed dedifferentiation arising from well differentiated thyroid carcinomas. Only one de novo PDTC showed highly cellular smears composed of discohesive small cells, high nuclear/cytoplasmic (N/C) ratio, prominent micronucleoli, and irregular nuclei. Retrospectively reviewed, these findings are highly suspicious for PDTC. Cytologic findings of nuclear atypia, pleomorphism, and irregularity were frequently found, whereas scattered small cells were seen only in the de novo case.
Conclusions
Heterogeneous cytologic findings of PDTCs are shared with those of WDTCs and contribute to difficult preoperative cytologic diagnoses. Most PDTCs show dedifferentiation from WDTCs. Albeit rare, de novo PDTC should be considered with cytology showing discohesive small cells with high N/C ratio. This will enable precise diagnosis and prompt treatment of this aggressive malignancy

PURPOSE: To evaluate the MR findings of transient synovitis of the hip in children. MATERIALS AND METHODS: Between 1993 and 1997, MR imaging was performed in 30 children(male:female=22:8) in whom transient synovitis had been clinically diagnosed. In 20 of these 30 patients, Gd-en-hanced study was also performed. The signal intensity of bone marrow of the femur, the synovial enhancement pattern and the amount of hip joint effusion in affected hips were evaluated; the last-mentioned was determined using the volume measurement method. RESULTS: In 29 patients(97 %), no abnormal signal intensity was seen in bone marrow of the femur in affected hips. Gd-enhanced MR imaging revealed synovial enhancement of affected hip joints, as follows: minimal en-hancement in eight patients(40 %), moderate enhancement in eight(40 %), and strong enhancement in four( 20%). No abnormal enhancement was demonstrated in bone marrow of the femur or adjacent soft tissue. The mean amount of joint effusion of affected hips was 2.7 +/- 1.7(range, 0.2 -18.9)ml; statistically, this was much greater than that of contralateral hip (p<0.01). CONCLUSION: The MR findings of transient synovitis of the hip in children were normal bone marrow signal intensity of the femoral head, moderate or strong synovial enhancement, and asymmetric hip joint effusion.

One lung ventilation for thoracic surgery may reduce arterial oxygen saturation by ventilation-perfusion mismatching and by increasing intrapulmonary shunting. We experienced a 52 year old male patient with a lung abscess, who showed arterial desaturation after one-lung ventilation. The authors tried to increase arterial oxygen saturation by applying positive end-expiratory pressure (PEEP) and continuous positive airway pressure (CPAP) to dependent and nondependent lung, respectively. However, arterial oxygen saturation did not increase. So, we applied partial differential lung ventilation using an open-close valve designed by the authors, and arterial oxygen saturation increased rapidly. The advantages of the open-close valve are its straightforward use and ease of manipulation. We report a case involving the use of this open-close valve in a desaturated patient during one lung ventilation.
