BACKGROUND: This study aims to examine the knowledge of nursing and allied health-college students on cough etiquette and their actual compliance to it. METHODS: For data collection, a structured questionnaire was created and handed out to students from 3 colleges from November 9 to November 18, 2011. The questionnaires were distributed to 300 students, and responses from 253 students were used for data analysis. RESULTS: In total, 54.85% students provided correct answers to questions regarding their knowledge on cough etiquette. The compliance score was 34.39 (compliance rate: 61.41%). There was a positive association between knowledge of proper cough etiquette and compliance with those procedures. CONCLUSION: It can be concluded that college student's knowledge of cough etiquette is low, and subsequently that their compliance with the proper procedures of cough etiquette was low. Therefore, it is necessary to develop a program to build knowledge of proper cough etiquette amongst these students.

Many graft materials are available for surgical treatment of maxillofacial bony defect and deformity. Despite concerted efforts to gain comparable outcomes with allogenic bone, xenogenic bone, bone substitutes, and alloplasts, the results related to function, from and adaptibility remain superior with autogenous bone. The cancellous bone is relatively more osteogenic than cortical bone. The superior osteogenic properties of cancellous bone has been widely used an oral and maxillofacial surgery. Well-recognized donor sites of cancellous bone have included ilium, rib and calvarial bone, But the procurement of cancellous bone from any site should be no considered biologic insult to the patients. The proximal tibia as an alternative donor site has the potential to yield viable cancellous bone with a minimum of morbidity. We experienced several jaw defect treated with autogenous proximal tibial cancellous bone grafting. The harvested cancellous bone was soft and easily molded to fill defects and the recipient site showed a favorable result. Moreover, with uneventful healing process, the donor site showed the overall lack of morbidity. This report presents clinical applications of the autogenous cancellous bone graft from the proximal tibial metaphysis and satisfactory results to repair of the jaw defect.

PURPOSE: Sexual differences in the incidence and crystalline composition of urinary stones in humans are well-known, but it is unclear why men have a higher incidence of calcium oxalate stones than women. We investigated the effects of male sex hormones on stone formation using an ethylene glycol (EG) - induced urolithiasis model in rats. MATERIALS AND METHODS: Adult male Sprague-Dawley rats were divided into 4 groups, each containing 10 rats. One group of rats was left untreated and served as control. The other 3 groups were fed a 1% ethylene glycol (EG) lithogenic diet for 4 weeks. Among these, one group was non-castrated, one group was castrated and one group was non-castrated and given finasteride orally. Serum testosterone, creatinine, electrolytes, 24-hour urine levels of oxalate and citrate, and creatinine clearance were measured. The crystal deposits were examined by light and polarizing microscopes. RESULTS: Testosterone promoted calcium oxalate stone formation in EG - treated rats. Finasteride administration significantly decreased urinary oxalate excretion and calcium oxalate deposition, compared with controls. Urinary citrate was significantly decreased in EG-treated rats, but was not influenced by castration or administration of finasteride. There were no significant differences in serum concentrations of creatinine, sodium, or potassium among the control and experimental groups. CONCLUSIONS: Our data suggest that testosterone promotes calcium oxalate stone formation, and that dihydrotestosterone may be partially responsible for the exaggerated hyperoxaluria in EG-treated rats. Additionally, male sex hormones have a lesser influence on urinary citrate than oxalate.

Malignant transformation of benign cystic teratomas of the ovary is rare, with an incidence rate of 1-3%. The most common malignancy associated with benign cystic teratoma of the ovary is squamous cell carcinoma, which represents 90% of malignant transformations, followed by adenocarcinoma and carcinoid. Primary malignant neuroectodermal tumor in a mature cystic teratoma is extremely rare and microscopically can be subclassified as differentiated, primitive, and anaplatic. We experienced a case of primitive neuroectodermal tumor (PNET) associated with mature cystic teratoma of the ovary in a 11-year-old girl. Grossly, the ovary was a unilocular cyst which contained sebum material and disclosed several large, yellow to gray-tan polypoid excresences attached to the inner cystic wall. Except a large, fish-flesh, soft mass, the other polypoid masses were covered with sebum and contained small pieces of cartilage and tooth, and microscopically represented as mature teratoma. The large, fish-flesh, soft mass disclosed sheets and lobules of closely packed small cells with thin fibrovascular septa, which frequently replacing and encroaching the mature cystic teratoma. The small tumor cells were uniform and made up of round to oval nuclei with coarse chromatin and prominent nucleoli, very similar to those of PNET of the central nervous system.

Purpose: The purpose of this study was to suggest the importance of natural childbirth by investigating the results of midwife-led perinatal periods and whether they were positive experiences for both individual women and their families. Methods: This retrospective study aimed to confirm the perinatal outcomes of midwife-attended vaginal births. Among 1,127 women who gave midwife-led birth in Gyeonggi-do, Seoul between January 1, 2019 and December 31, 2021, data were collected for 829 women. Records were excluded that were missing necessary data. Data on childbirth were analyzed using frequency, percentage, mean, standard deviation, and the chi-square test. Results: Among the mothers who underwent natural childbirth, 549 (66.2%) were multiparous. In addition, all 829 patients (100%) breast-fed their infants. First-degree perineal lacerations occurred in 29.2% of patients, and second-degree lacerations occurred in 48%. Non–high-risk subjects made up 56.0% of the study sample. The average bleeding amount was 281.44±4.50, and the average 1-minute Apgar score for infants was 8.25±0.02. Conclusion Compared to childbirth in a hospital, natural childbirth was associated with a lower risk of birth canal laceration, postpartum bleeding, and Cesarean section. In addition, the health statuses of the newborns were confirmed to be good . Based on the results of this study, there is a need for a strategy in which midwife-led natural childbirth is integrated into the local medical system, as well as a need to raise women's awareness of natural childbirth and positively influence the experience.

The causes of hypocalcemia in patients suffering from severe infection including sepsis are largely uncertain. So we measured serum albumin, total protein, cholesterol, PTH, and calcitonin of the infection-associated hypocalcemic children and compared with those of normocalcemic children suffering from tsutsugamushi disease. All had normal renal functions and had been admitted to the department of pediatrics of Gyeongsang National University Hospital. Hypocalcemic patients were hypoalbuminemic. Serum total calcium was inappropriately more decreased compared to the decreased amount of serum albumin in the hypocalcemic group. We also observed more frequent incidence of hypocholesterolemia (<100mg/dL) in this group. And serum PTH was appropriately elevated in the hypocalcemic patients. Serum calcitonin was elevated in both groups, but 6 times higher in the hypocalcemic group than in the normocalcemic one. Serum total calcium was positively correlated with serum albumin and negatively correlated with serum PTH and calcitonin.

This study was performed to assess the accuracy of 31P magnetic resonance spectroscopy(MRS) in the evaluation of myocardial ischemia in cats. Twelve cats underwent myocardial ischemia and reperfusion induced by 90 minutes ligation followed by 90 minutes recirculation of the left anterior descending coronary artery (LAD). MRS was performed using a 4.7T Biospec MRS/MRI system (Bruker, Switzerland). An inner diameter 1.5cm-sized doubly tuned surface coli was used for the collection of the MR signal. The coli was implanted to the epicardial surface at the expected area of infarction. 31P MRS was acquired before and during the periods of ischemia and reperfusion with 5-minute to 30-minute of intervals. After completion of the 31P MRS study, animals were sacrificed and the hearts were excised for 2,3,5-triphenyl tetrazolium chloride (TTG0 histochemical staining. The area of infarct was measured on the photographs of TTG stained heart slices using a computer programmed planimetry and the results were compared with those of the 31P MRS study. The level of phosphocreatine (PCr) was decreased to 28.2±6.9% of the baseline level 90 minutes after occlusion and recovered to 43.8±4.8% of the baseline level at the end of the reperfusion. A 50% depletion of PCr was reached 5 minutes after the LAD occlusion. The ATP was decreased to a 26.6±3.6% of the baseline level 90 minutes after occlusion and recovered to a 35.9±6.0 of the baseline level 90 minutes after reperfusion. The decreasing rate of ATP was slower than that of PCr showing a 50% of depletion 15 minutes after occlusion. The PCr/ATP ratio was 1.16±0.09 at the baseline, decreased to 0.88±0.07 at 30 minutes of occlusion, and then progressively increased during the late ischemic and reperfused periods. The ratio of the infarcted area to the effective signal area of the surface coli was inversely correlated to the ATP (r=0.68) and PCr (r=0.40) levels obtained at the end of reperfusion. In conclusion, 31P MRS reflects the changes in myocardial high energy phosphorous metabolism during the actue ischemia and reperfusion. If on adequate localization technique is feasible, 31P MRS can be used clinically in the diagnosis and monitoring of the patients with acute myocardial infarction.
