BACKGROUND: Acute dissection of the thoracic aorta can mimic the symptoms of myocardial infarction with pain, elevated serum creatinine kinase levels, and electrocardiographic abnormalities suggesting myocardial ischemia. Therefore, this study was designed to assess the clinical differences between a thoracic aortic dissection and an acute myocardial infarction. METHODS: The cases of 72 patients who visited the Emergency Department, Dankook University Hospital, from January 1996 to December 1998 were retrospectively reviewed. Of the 72 patients, 32 were thoracic aortic dissections and 40 were acute myocardial infarctions. The parameters analyzed were epidemiology, pain character and associated symptoms, simple X-rays, EKGs on arrival. RESULTS: This study demonstrated that 1) there were significant differences in the nature, location, and duration of pain, the radiation, the neurologic symptoms, the chest X-rays, and the EKGs between the two groups and that 2) there were no significant differences in pain severity and abrupt onset. CONCLUSION: This study suggests that patients with suspected acute myocardial infarction should be provided an appropriate, accurate technique, such as CT, MRI, or TEE, if the nature, location, and duration of pain, the radiation, the neurologic symptoms, the chest X-ray, and the EKG are consistent with a thoracic aortic dissection.

The purpose of this study was to investigate the characteristics or the potassium channels existing in the rat urinary bladders. Smooth muscle strips of rat detrusor urinae were examined by isometric myography. Relaxation responses of detrusor muscle strips to the three potassium channel openers pinacidil, a cyanoguanidine derivative, BRL 38227, a benzopyran derivative and RP 52891, a tertrahydrothiopyran derivative were examined. The potassium channel openers reduced the basal tone, and the rank order of potency was RP 52891>pincidil>BRL 38227. Procaine, an inhibitor of the voltage-sensitive potassium channel tended to increase the basal tone, but it did not affect the relaxant effects of the calcium-activated potassium channel opener did not antagonize the relaxant effects, but it reduced the Emax of RP 52891 and BRL 38227. Glibenclamide, an inhibitor of the ATP-sensitive potassium channel, antagonized the relaxant effects of pinacidil, RP 52891 and BRL 38227 reducing the Emax of RP 52891 and BRl 38227. Galanin which inhibits secretion of insulin through opening the ATP-sensitive potassium channels in pancreatic β-cells rather increased the basal tone of the isolated detrusor strips. These results suggest that the urinary bladder of the rat has mainly the ATP-sensitive, glibenclamide sensitive potassium channel, which is a different type from that in the pancreatic β-islet cells.

A wide variety of cancers metastasize to the ovaries. In a majority of instances the primary site is the gastrointestinal tract, breast, or other gynecologic organs. The best known tumor of this type is signet-ring cell adenocarcinoma. The gallbladder and bile duct are rare sources of these metastases. The authors have had an experience of a case that was presented of Krukenberg tumor metastatic from the gallbladder and report the case with brief review of literature.

Purpose:
The aim of this study was to analyze the prevalence of depression, anxiety, somatization disorder, and adjustment disorder in older patients diagnosed with exudative age-related macular degeneration (AMD) and to evaluate the relationship between exudative AMD and psychological disease.
Methods:
The 2016 Health Insurance Review and Assessment Service-Aged Patient Sample was applied in this study. The subjects were divided into two groups: AMD patients undergoing intravitreal injection treatment and a control group. Comorbidities were evaluated using the Charlson Comorbidity Index.
Results:
A total of 1,319,052 subjects were selected, of which 3,134 were in the exudative AMD group receiving intravitreal injections. The average age of the subjects was 74.7 ± 6.7 years, and 41.8% were male. In patients with exudative AMD, the prevalence of depression, anxiety, somatization disorder, and adjustment disorder were 16%, 20%, 0.5%, and 0.4%, respectively; in particular, the prevalence of depression and adjustment disorder were significantly higher than in the control group. In multivariate regression analysis, exudative AMD was a significant factor of depression (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.08-1.31, p < 0.001) and adjustment disorder (OR 2.47, 95% CI 1.47-4.18, p < 0.001). However, the association between AMD and anxiety or somatization disorder was not statistically significant.
Conclusions
Exudative AMD showed a significant association with psychiatric disease, such as depression, and requires close clinical attention.

Midazolam, a new water-soluble benzodiazepine, has a few important advantages over diazepam which are lack of vascular irritation and rapid onset and short duration of action. So it has been used for an induction agent for anesthesia. But there were many different reports about the effective dose of midazolam as an induction agent for anesthesia, and which showed intersubject variability. Therefore, this study was aimed to verify the effective induction dose of midazolam comparing with thiopental 5 mg/kg for general anesthesia. The patients were divided into 6 groups. The patients of group 1, 2, 3, 4, and 5 were injected midazolam 0.15, 0.20, 0.25, 0.30, and 0.35 mg/kg, respectively, and, of group 6, thiopental 5 mg/kg for induction of anesthesia. Induction of anesthesia was defined as complete with loss of eyealsh reflex and failure to verbal commands. Unless induction was attained within 3 minutes, it was considered as failure of induction, and further steps of study were discontinued. After anesthesia was induced, stimulus to trapezius muscle relevant to endotracheal intubation was applied. The blood pressure, heart rate and arterial oxygen saturation were recorded before induction, at induction, and 1, 2, and 3 minutes after a stimulus to trapezius muscle. The incidences of pain on injection, venous irritations and antegrade amnesia were evaluated. The results were as follows; 1) Induction fractions of group 1, 2, 3, 4, 5, and 6 were 21.5, 57.2, 81.9, 100, and 100%, respectively. Induction times of group 1 to 5(midazolam groups) were 74.7-87.9 sec.(raanges, 40 -150 sec.) and, of group 6, 39.5 sec.(ranges, 33-55 sec.). But there was no relationship between midazolam doses and induction times. 2) At induction, systolic blood pressures of patients in group 3, 4, 5, and 6 decreased 6.1%, 5.8%, 10.5%, and 8.8%, respectively, and remained so after stimulus to trapezius muscle, but in group 6, which returned to preinduction value. Changes in sytoiic blood pressure were statistically insignificant among groups. 3) At induction, diastolic blood pressures of patients in group 5 and 6 decreased 11.0% and 11.3%, respectively, and, after stimulus to trapezius muscle, diastolic blood pressures did not change in group 3, 4, and 5, but, in group 6, returned to preinductuin value. Changes in diastolic blood pressure were statistically insignificant among groups. 4) At induction, heart rates of patients in group 3, 4, 5, and 6 increased 10.0%, 13.8%, 7.5%, and 25.8%, respectively. Changes in heart rate were significantly different between group 6 and other groups. 5) Arterial oxygen saturations decreased 0.25%, 0.3%, and 0.35% in group 3, 4, and 5 at induction, respectively, but, in group 6, decreased 3.4% after stimulus to trapezius muscle. Changes in arterial oxygen saturation were statistically insignificant among groups. 6) There were no differences in incidences of pain on injection, venous irritations, and antegrade amnesia among groups. In summary, midazolam can be used to induce general anesthesia safely with dose of 0.25 mg/ kg to 0.35 mg/kg, although there remains intersubject variability.
