A 58-year-old male presented with a pruritic, erythematous hread-like eruption on the right chest, which appeared as a small papule since 6 months prior to his visit. Histopathologic examination showed a burrow containing numerous eosinophiles and a few mononuclear cells in the epidermis. There was focal spongiosis unde the burrow. In the dermis, there was a diffuse and occasionally dense perivascular and periadnx 1 inflammatory cell infiltration consisting of eosinophiles and some lymphocytes. Multiple histologic sections were made without success in deizo strating parasitic tissue in the epidermis, however, the clinical and histopathologic features we onsistent with cutaneous larva migrans.

We report a case of a 44 year old femele with unilateral aldosterone-proudcing adrenal adenoma characterized by hypertension, plasma aldosterone excess, and low plasma renin, commonly but not invariably with hypokalemia. She also had asymmetric septal hypertrophy of left ventricle established with two-dimensional echocardiography. The electrocardiogram showed inverted T wave and prominent U wave with high QRS voltage on precordial leads. In the case of this patient, we are not sure whether asymmetric septal hypertrophy was caused by secondary hypertension and chronic aldosterone excess of primary aldosteronism, or hypertrophic cardiomyopathy per se, so further long=term follow-up is required to determine it. Following the successful unilateral adrenalectomy, however, the systemic pressure fell down to the normal level and electrolyte abnormalities were corrected immediaterly within a few days and the modest regression in septal hypertrophy was noted in one year, suggesting that the promary aldosteronism contributes to the development or porgression of asymmetric septal hepertrophy.

Although ventricular pacing alone initially had deemed adequate for most clinical situations, some patients did not do well after ventricular pacing was initiated, and developed various symptoms attributed to this mode of pacing. The pacemaker syndrome is complex of clinical signs and symptoms related to the adverse hemodynamic and electrophysiologic consequences of ventricular pacing in the absence of other causes. Neurologic symptoms or those congestive heart failure predominated. We recently experienced a case of pacemaker syndrome in a 44-year-old female who had suffered sick sinus syndrome and was implanted with dual chamber pacing system being programmed to VVI pacing. She complained of chest discomfort, dyspnea, and near-fainting in a day after being programmed to VVI. Blood pressure was decreased to 9/60mmHg. Electrocardiography showed toPwave onT wave, representing retrograde ventriculoatrial conduction. The symptoms and signs were disappeared immediately after the pacing system was programmed to DDD pacing.

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.

BACKGROUND: Blunted perception of dyspnea, which may be related to the increased mortality, has been demonstrated in patients with a history of near-fatal asthma and in the elderly. OBJECTIVE: The purpose of this study was to evaluate the relationship between the perception of dyspnea and the severity of asthma. METHOD: Baseline spirometry and Borg score change(A Borg score) during breathing through an inspiratory muscle trainer were measured in 27 consecutive asthma patients and 11 normal subjects. RESULTS: The baseline Borg score was negatively related to FEV1 A Borg score was significantly lower in asthmatics than in controls at high level of loads. A Borg score was lower in severe asthma than in mild asthma. A Borg score was positively related to the baseline FEV1. Seventy-five percent of severe asthma, 62.5% of moderate one, and 9.1% of mild one showed impaired dyspnea perception. Dyspnea perception was related to age(r, = -0.49, p<0.001). CONCLUSION: Three quarters of patients with severe asthma showed impaired dyspnea perception to inspiratory resistive load. Dyspnea perception was related to asthma severity and age.

PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

BACKGROUND AND OBJECTIVES: Perfluorocarbon exposed sonicated dextrose albumin (PESDA) microbubbles has been suggested to facilitate thrombus disruption under the transcutaneous ultrasound (US). Thus, we investigated whether such a noninvasive approach could augment thrombolytic effect of fibrinolytic agent in an experimental thrombotic model. MATERIALS AND METHODS: Thrombus formation was induced with electrical injury in the rabbit iliofemoral arteries (n=20): Thrombus occlusion was documented by angiography in all arteries. In the control group, only tissue plasminogen activator (t-PA, 3 mg/kg) was administered intrav-enously in five rabbits. In the Group 1 (n=9), injured arteries were exposed to transcutaneous US (20 kHz, 30 W/cm2, continuous mode) with t-PA (3 mg/kg). In the Group 2 (n=6), the same treatment was given while administering PESDA continuously (10 ml/min, intravenous). Angiographic results were evaluated at 10 minute interval for 1 hour respectively. RESULTS: In the control group, two of five iliofemoral arteries (40.0%) were recanalized and one of nine iliofemoral arteries (11.1%) was recanalized in Group 1. In contrast, four of six iliofemoral arteries (66.7%) were recanalized angiographically in Group 2 (p=0.392 vs. control group: p=0.047 vs. Group 1). However, late reocclusion occurred in all iliofemoral arteries of Group 2. CONCLUSION: Although PESDA with transcutaneous US significantly enhanced initial angiographic patency rate of t-PA, it was associated with high rate of reocclusion. Further studies will be necessary for clinical application of this noninvasive method in acute arterial occlusion.
