A 21-year-old man presented with a 7 days history of fever. Careful clinical examination led to the discovery of left supraclavicular lymphadenopathy without hepatosplenomegaly. Serologic tests for Ebstein-Barr virus, HIV, hepatitis type B & C, syphilis and typhoid fever were negative. Blood, urine, and stool cultures yielded no growth. Histologically, the process mainly involved the connective tissue framework of the lymph node, sharing the features of inflammatory pseudotmor(IPT) of other organs: a storiform growth pattern, increased vascularity with associated vascular lesions, and a polymorphous inflammatory infiltrate in a collagen-rich stroma. Immunohistochemical study for spindle cells showed positive reaction for actin and vimentin but not for desmin, and lymphoid cells revealed polyclonality. Characteristics of mass formation, and the inflammatory nautre of the process enabled us adopt the term IPT which should be differentiated from hematolymphoid proliferative disorder or mesenchymal neoplasia.

We report the dynamic magnetic resonance imaging findings (MRI) of a metaplastic carcinoma of the breast. A 44-year-old woman presented with a 2-month history of a mass in the right breast. The tumor showed a central irregular necrosis that was depicted upon low signal intensity on a T1-weighted image and high signal intensity on a T2-weighted image. The periphery of the tumor showed strong enhancement on a contrast enhanced T1-weighted image. The time-signal intensity curve revealed an early strong contrast enhancement and a delayed washout pattern.

BACKGROUND: Recently in Europe, some epidemiologic studies reported that various physical symptoms and social, psychological wellbeing are related to low blood pressure. But in Korea, none has been studied on symptoms related to low blood pressure yet. In this study, we would like to see if the somatic symptoms and social, psychological wellbeing shown t,o be related to low SBP is truly associated with it. METHODS: Questionnaire interview was done to the people who have visited Department of family practice in two university hospitals and two health promotion center from April, 1996 to August, 1996. Seven somatic symptoms and Psychosocial Wellbeing Index(PWI) for the evaluation of social, psychological health status were included in the questionnaire. SAS statistics packages was used in statistical precess. We used logistic regression to see the frequency of somatic symptoms related to the systolic blood pressure(SBP) group and the confirmation of confounding variables was done by ANOVA. RESULTS: Total of 304 completed the questionnaire. Average age was 44 years old and average SBP was 115.4+/-16.4. 84 of them (27.6%) felt that they had a low BP & 69 were women compared to 21 men, being meaningfully more common. 107(35.2%) people answered that they had heard that their blood pressure was low and 66% were from doctors. Only 32(38.1%) of the group who felt of having hypotensive symptoms and 38 of the group who heard of having hypotension actually had SBP of below 100 mmHg. Vocation, income, smoking & alcohol history, present illness, marital status were not significant as a confounding variable. SBP of 100 or below group had a less presentation of fatigue & significantly higher PWI than the group of above 100mmHg (p<0.05). The group who felt that they had a low BP had more complaints of fatigue, dizziness, palpitation, cold hands and feet and had significnatly higher PWI than the group who didnt. CONCLUSIONS: SBP of 100mmHg or below group has more frequent manifestion of fatigue and low level of sociopsycholgiacl health index than the above 100mmHg group. But most of the people who complained of hypotensive symptoms didnt have low blood pressure and a lot of them misunderstand of having low blood pressure and after checking blood pressure by doctors, so great deal of caution is called for when seeing patients.

BACKGROUND: Under normal conditions, cerebral blood flow is regulated as cerebral perfusion pressure changes (autoregulation). Inflammatory conditions like bacterial meiningitis result in a loss of cerebral autoregulation several hours after exposure to bacterial endotoxin. Endotoxin appears to produce effects via the production of reactive oxygen species, such as the superoxide anion. METHODS: Cerebral blood flow (CBF) was measured by hydrogen clearance in anesthetized rats 30 minutes after intravenous endotoxin 5 mg/kg or normal saline (control). Mean arterial pressure was reduced from 100 mmHg to 80 mmHg and 60 mmHg by hemorragic hypotension, and cerebral blood flow was measured at each pressure. RESULTS: In the control group, CBF did not change when arterial pressure was reduced to 80 mmHg (113.9 ml vs 111.9 ml), but declined significantly at 60 mmHg (113.9 ml vs 88.4 ml). In the group treated with endotoxin, both a reduction of mean arterial pressure to 80 mmHg (129.8 ml vs 101.8 ml) and 60 mmHg (129.8 ml vs 78.4 ml) caused a significant reduction in CBF, indicating that autoregualtion had been abolished. CONCLUSIONS: The results of this study indicate that within minutes of endotoxin exposure, CBF markedly increased, and that the autoregualtion of CBF was inhibited.

An intrauterine device (IUD) is one of the most commonly used contraceptive method in the world. One of the major complications of intrauterine contraception is the perforation through the uterine wall into the pelvic or abdominal cavity. The incidence is 0.9 people per 1000. However, bladder perforation is even more rare. It happens mostly at the time when it was inserted. The symptom varies from no symptom at all to low abdominal pain, massive bleeding, et cetera. We report a case with displaced intrauterine device in bladder, producing the bladder stone which was managed with cystoscopic lithotripsy and intrauterine device removal, followed by a review of the literature.

The simultaneous existence of intrauterine and extrauterine pregnancies is known as a heterotopic pregnancy. Spontaneous heterotopic pregnancy is a rare event although its incidence has increased since the recent development of treatment of infertile women with ovulation induction or in-vitro fertilization and embryo transfer(IVF-ET).The theoretical rate of this condition was estimated to be approximately 1 in 30,000 pregnancies. The early diagnosis of heterotopic pregnancy is very difficult . So there is a high maternal morbidity and fetal loss. We reported a IVP - ET patient resulting in the successful delivery of live infant at 35weeks of gestational age from intrauterine pregnancy following surgical removal of ruptured concurrent extrauterine pregnancy.

BACKGROUND: To determine the relationship between nutrient intake and bone mineral density(BMD), we have investigated this issue by the use of a semiquantitative food-frequency questionnaire. METHODS: A total of 312 women aged 33-77 was divided into two groups, 187 premenopausal and 125 postmenopausal women. Dietary intake was assessed with a food-frequency questionnaire. DMD was assessed with dual-energy X-ray absorptiometry at the lumbar spine (lumbar vertebrae 2-4). Pearson correlation and partial correlation coefficients were calculated for each nutrient at the lumbar spine BMD. RESULTS: The mean age of the 312 participants was 48 years, and their mean body mass index (BMI) was 23.7+/-2.8 Kg/m2. Forty percent of the women were in postmenopausal state. The mean lumbar BMD was 1.117g/cm2. Age was negatively correlated with BMD in premenopausal and postmenopausal women, BMI was positively correlated with BMD in postmenopausal women, but smoking and exercise were not correlated with BMD. In premenopausal women, nutrient intakes were not associated with BMD. A significant association was found between intakes of fat, iron, vitamin A, vitamin C and BMD in postmenopausal women, but after adjusting for age, body mass index, energy intake, smoking, exercise, and use of hormone replacement therapy, there was no association. CONCLUSION: There was no significant association between nutrient intakes and BMD of the lumbar spine.
