OBJECTIVE: Our purpose was to describe the clinical progress and the maternal and fetal outcome in 16 pregnancies complicated by the HELLP(hemolysis, elevated liver enzymes, low platelet). Material: We reviewed the maternal and neonatal charts from 16 consecutive pregnancies complicated by the HELLP syndrome among 302 pregnancies complicated by preeclamsia and eclamsia managed at our hospital during the period of 4 years from June 1994 through June 1998. The HELLP syndrome was defined by previously published laboratory criteria. We assessed the time of onset, presenting symptom, laboratory finding, mode of delivery, fetal and maternal complication in each case. We also reviewed the clinical finding in detail in the case resulted in maternal death. RESULTS: In regards to the time of onset, 15 cases (93.7%) occurred at antepartum period and only 1 case (6.2%) occurred at postpartum period. Among the 15 cases occurred at antepartum period, 13 cases (81.25%) developed at 27 to 36 weeks gestation and 2 cases (12.5%) developed at near term. In regards to the presenting symptom, twelve patients (75%) complained of right upper quardrant or epigastric pain. Of 16 patients, 12 patients (75%) experienced headache and 10 patients (62.5%) complained of nausea, or vomiting and 5 patients (31.2%) had visual disturbance. The laboratory finding of all 16 cases were as follow; the mean level of platelet: 68700/mm3 (range: 48000 to 91700), the mean level of serum asparate aminotransferase: 335 IU/L (range: 62 to 135), the mean level of lactic dehydrogenase: 910 IU/L (range: 558 to 5794), and the mean level of total bilirubin: 2.6 mg/dl (range: 0.7 to 10.4). To review the mode of delivery, cesarean sections were done on 10 patients (62.5%) including 7(43.7%) emergency and 3(18.7%) elective operations. However, 6 patients (37.5%) delivered vaginally. Maternal complications were as follow; abruptio placenta in 1 case (6.2%), DIC in 2 cases (12.5%), pulmonary edema in 3 cases (18.7%), pleural effusion in 4 cases (25%), renal failure in 4 cases (25%), and 1 case of death. Fetal and neonatal outcome was assessed; 9 cases of intrauterine growth retardation (56.2%), meconium stained in 3 cases (18.7%), 2 stillbirth (12.5%), and 2 neonatal death (12.5%). CONCLUSION: HELLP syndrome is associated with serious maternal and fetal morbidity and mortality.

"The prenatal diagnosis of spine bifida include the combined use of maternal serum alpha-fetoprotein (MSAFP) screening and fetal sonography. Sonographically, spina bifida is characterized by direct signs of the visualization of the spinal defect, and indirect signs of the cranial markers : the lemon sign, the banana sign, and ventriculomegaly. These ultrasonographic signs are more accurate in defining the cranial malformations associated with spina bifida than evaluation of the spine. Recently, three cases of spina bifida which was diagnosed as ""splaying"" of the posterior ossification centers, meningomyelocele sac at the lumbosacral area, lemon sign, banana sign and ventriculomegaly by ultrasonography at 21+2 gestational weeks in a 32 years old nullipara, at 21+2 gestational weeks in a 26 years old nullipara, at 23+6 gestational weeks in a 26 years old multipara were experienced at our department. We present this cases with a brief review of literatures"

Duchenne muscular dystrophy (DMD) is a degenerative muscle disease characterized by a progressive decline in muscular function, with cardiomyopathy in the later stages. We report the autopsy findings of a 29-year-old man with DMD. He had been stable with the assistance of mechanical ventilation until he was found unconscious, without known cause. External examination confirmed generalized muscular atrophy and contracture consistent with his clinical history. Histopathology revealed varying degrees of fibrofatty changes in the muscles, with the calf muscles being the most extensively affected, followed by the diaphragm and heart. The cardiac muscle showed the least involvement and the pathology was confined to the left ventricular wall and the interventricular septum, exhibiting a unique morphology of fibrosis resembling stretched springs. The cause of death was attributed to cardiac failure due to DMD progression. This case highlights the clinical course of DMD, emphasizing the need for thorough examination of both skeletal and non-skeletal muscles, including the cardiac muscles, to obtain a better understanding of the disease.

OBJECTIVES: Mental fitness issues have recently become a point of dispute in the field of health. Drivers are occupationally in danger of a possible accident, and are also exposed to other factors aside from accidents that threaten their mental health. The purpose of this research is to examine the level and state of post traumatic stress disorder (PTSD) and overall mental fitness in bus drivers. In addition, we wish to understand the various causes that can influence PTSD. METHODS: From April 1 to June 30, 2009, taking the region and number of workers into consideration, survey sheets were distributed to selected bus drivers who belonged to the public transportation union. The questionnaire included questions on experiences, details of accidents, the characteristics of the working environment, and the status of mental health. We used the Davidson Trauma Scale to investigate PTSD symptoms and the Center for Epidemiological Studies Depression Scale to evaluate depression. RESULTS: Regardless of the type of accident, the group of bus drivers with accident experience showed stronger signs of suffering from PTSD. It seemed that the experience of an accident that caused the death of passengers or conflict with passengers were important factors for PTSD. Within the PTSD group, we found more symptoms of depression, and also this group is more likely to take time off work. CONCLUSIONS: The experience of an accident threatens the mental health of bus drivers. Since bus drivers are responsible for the safety of many citizens, we must work towards finding ways to protect their mental health.

BACKGROUND: Shift work disturbs workers' biological clocks and this condition can cause various health problems including cardiovascular disease. The elevated albuminuria level has been significantly associated with the risk of the cardiovascular disease even within a normal reference range. Therefore, this study aimed to investigate the association between shift work and microalbuminuria. METHODS: Workers aged over 20 years from the fifth and sixth Korea National Health and Nutrition Examination Survey(KNHANES 2012–2014; n = 3000) were included in this analysis. The multiple logistic regression analysis was performed to determine the association between shift work and microalbuminuria stratified by gender. RESULTS: The prevalence of microalbuminuria in male subjects was higher among day workers, but the difference was not significant. However, the prevalence of microalbuminuria among females was higher in shift workers with statistical significance. For female, the Odds ratio of microalbuminuria in shift workers was significantly higher with 1.86 (95% CI 1.02–3.39) compared with day workers. After dividing into 5 subgroups of the shift work pattern, the odds ratio of microalbuminuria for fixed night shift was significantly higher at 4.68 (95% CI 1.29–17.00) compared with day workers. CONCLUSIONS: This study showed that shift work was associated with microalbuminuria in female workers. Especially we found out the association between fixed night shift and microalbuminuria in female workers.

Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited colon cancer-predisposing disorder, characterized by the development of innumerable adenomas in the large intestine. Polyps are present in the upper gastrointestinal tract in almost all FAP patients and there is a peculiar predilection for adenomatous change in the duodenum. Colonic adenomas in FAP are commonly observed as polyps but nonpolypoid adenomas can also be seen in the upper gastrointestinal tract. Careful endoscopic examination is needed for detecting such nonpolypoid lesions. At present, the adenoma-carcinoma sequence is thought to exist also in the duodenum, and malignancy of the duodenum represents one of the most common causes of mortality among patients with FAP. Therefore, careful periodic follow-up of upper intestinal endoscopies are recommended in patients with this disease, in consideration to the possible development of duodenal nonpolypoid adenomatous lesions. A case involving an experience of antral and duodenal nonpolypoid adenomas in a patient with FAP is herein reported.
