Thyrotoxicosis (thyroid crisis) is a known cause of sudden death; however, only a few cases of death resulting from thyrotoxicosis have been reported. Histopathologic examination and postmortem thyroid function tests may be helpful in postmortem diagnosis, but their usefulness seems to be limited. We report three autopsy cases associated with thyrotoxicosis.

By means of hospital-based data over 8 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristic and reproduction history. From the obstetric record of all deliveries at Chung Goo Hospital between Jan. 1, 1990, and Nov. 31, 1997, we identified all women undergoing emergency cesarean hysterectomy, calculated incidence rates, conducted statistical tests of linear trends and heterogenety, and observed the clinical indicatons preceding the onset of this procedure. There were 16731 deliveries during this period, Cesarean hysterectomy was performed in 24 of 5993 cesarean sections(0.40%) and in 10 of 10738 vaginal deleveries(0.09%), so more frequently after cesarean section than vaginal delivery. The age of patients varied from 22 to 40 years old. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(52.94%) followed by placental disorders(41.18%), uterine myoma with pregnancy(2.9%) and uterine rupture (2.9%). All patients who had hysterectomy received transfusion from 1 pint to 57 pints. The postoperative complications were bladder injury, febrile morbidity, disseminated intravascular coaguolopathy and wound disruption. There were three maternal deaths, the cause was disseminated intravascular coaguolopathy and amniotic embolism. The data identifiy uterine atony as the primary cause for gravid hysterctomy. The data also illustrated how the incidence of emergency peripartum hysterectomy increases significantly with increasing parity, especially when influenced by a current placenta previa or a prior cesarean section. Maternal morbidity remained high.

3.Analysis of Workplace Health Education Performed by Occupational Health Managers in Korea.
Asian Nursing Research 2016;10(3):246-253
PURPOSE: To evaluate workplace health education as practiced by occupational health managers based on standardized job tasks and suggest priority tasks and areas to be trained. METHODS: The study was conducted between November 10, 2013 and April 30, 2014. The tool used in this study was standardized job tasks of workplace health education for occupational health managers which was developed through methodological steps. It was evaluated by 233 worksite occupational health managers. Data were analyzed using SPSS 21.0. RESULTS: Predicting variables of workplace health education performance were the "analysis and planning" factor, type of enterprise, and form of management. Healthcare professionals and occupational health managers who managed the nonmanufacturing industry showed high importance and low performance level in "analysis and planning" factor. CONCLUSIONS: "Analysis and planning" skill is priority training area for healthcare professionals and occupational health managers who managed nonmanufacturing industry. It is necessary to develop a training curriculum for occupational health managers that include improving analysis of worksites and plans for a health education program.

Purpose:
Children have few small alveoli, which reduce lung compliance; in contrast, their cartilaginous rib cage makes their chest wall highly compliant. This combination promotes lung collapse. Prolonged inspiratory to expiratory (I:E) ratio ventilation is used to optimize gas exchange and respiratory mechanics in surgery. However, the optimal ratio is unclear in children. We hypothesized that, compared to a 1:2 I:E ratio, a 1:1 I:E ratio would improve dynamic compliance and oxygenation, and affect the peak airway pressure in pediatric patients undergoing surgery.
Materials and Methods:
Forty-eight patients aged ≤6 years who were scheduled to undergo surgery under general anesthesia with an arterial line were randomly allocated to receive 1:1 (group 1:1) or 1:2 (group 1:2) I:E ratio ventilation. Airway pressure, respiratory system compliance, and arterial blood gas analyses were compared between groups immediately after induction (T0), 30 min after induction (T1), 60 min after induction (T2), immediately after surgery (T3), and on arrival at the post-anesthesia care unit (T4).
Results:
Peak and plateau airway pressures were significantly lower in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.048, respectively). The dynamic and static compliances were significantly higher in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.045, respectively). However, the partial pressure of oxygen did not significantly differ between groups.
Conclusion
Compared to a 1:2 I:E ratio, a 1:1 I:E ratio improved dynamic compliance and lowered the peak airway pressure without complications in pediatric patients. Nevertheless, our results do not support its use solely for improving oxygenation.

We report a case of an erythrodermic form of mycosis fungoides in a 68-year-old male, who showed generalized erythroderma with scales for 3 months. Lymphadenopathies in the inguinal and neck areas were present. Histopathological findings showed epidermotropism, perivascular atypical lymphocyte infilteration in the upper dermis, and dermatopathic lymphadenopathy in the inguinal lymph node. T cell markers were positively stained in the immunohistochemical study. These clinicopathological features were consistent with an erythrodermic form of mycosis fungoides(TNM IIl). The patient was treated with PUVA therapy and low dose chemotherapy.

Paragonimus westermani can cause extrapulmonary parasitism in various sites such as abdominal organ, brain, eye, periorbital tissue, heart and pericardium, mediastinum, and subcutaneous tissue. We experienced a case of subcutaneous paragonimiasis involving the breast. The lesion exhibited chronic granuloma with scattered eggs of paragonimus westermani. The adult worm was not found within the lesion which should be disintegrated a year ago by praziquantel treatment. This relatively rare involvement of ectopic paragonimiasis should be differentiated from breast malignancy.

PURPOSE: This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. METHODS: A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, chi2-test, t-test, and ANCOVA with the SPSS 18.0. RESULTS: The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to 'metric conversion' (t=2.25, p=.027), 'table dosage calculation' (t=2.20, p=.031) and 'drop rate calculation' (t=4.60, p<.001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. CONCLUSION: These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.

This study aimed to investigate the prevalence of symptoms of shift work disorder (SSWD) and its related factors in rapidly rotating three-shift nurses. Methods: We enrolled 344 nurses (mean age, 28.7 years) without prior history of sleep disturbance before starting shift work in a university-affiliated hospital. SSWD were defined using self-reported sleep questionnaires (insomnia severity index >14 and/or Epworth Sleepiness Scale ≥10) and without any sleep problem before shift work. Sleep pattern in each of the three shifts was measured using the Munich Chronotype Questionnaire for Shift-Workers. Mood (anxiety, depression) and job stress were also measured using self-reported questionnaires. Results: Our results showed that 62.2% of the participants presented SSWD. Compared to the non-SWD group, the SSWD group showed worse sleep hygiene, lower total sleep time (TST) during workdays, higher anxiety and depressive mood, and higher job stress. In the SSWD group, the evening chronotype individuals presented the shortest TST during day shifts, while the morning chronotype individuals presented the shortest TST during evening shifts. Conclusions: SSWD is highly prevalent in fast rotating three-shift nurses. This study suggests that intensive education on sleep hygiene and appropriate scheduling of shift work while considering individual chronotypes may improve sleep patterns and sleep quality of shift workers and minimize SSWD.

Dietary sodium intake is considered one of the major causal factors for hypertension. Thus, to control the increase of blood pressure and reduce the risk of hypertension-related clinical complications, a reduction in sodium intake is recommended. The present study aimed at determining the association of dietary sodium intake with meal and snack frequency, snacking time, and taste preference in Korean young adults aged 20-26 years, using a 125-item dish-frequency questionnaire. The mean dietary sodium intakes of men and women were 270.6 mmol/day and 213.1 mmol/day, which were approximately 310% and 245% of the daily sodium intake goal for Korean men and women, respectively. Dietary sodium intake was positively correlated with systolic blood pressure in the total group, and BMI in the total and men-only groups. In the total and men-only groups, those who consumed meals more times per day consumed more dietary sodium, but the number of times they consumed snacks was negatively correlated with dietary sodium intake in the total, men-only, and women-only groups. In addition, those who consumed snacks in the evening consumed more sodium than those who did so in the morning in the men-only group. The sodium intake was also positively associated with preference for salty and sweet taste in the total and women-only groups. Such a high intake of sodium in these young subjects shows that a reduction in sodium intake is important for the prevention of hypertension and related diseases in the future.
