BACKGROUND AND OBJECTIVES: The relationship of cold pressor, hyperventilation and exercise test responses to circadian patterns and types of angina in vasospastic angina have still not been known. The aim of this study was to identify subgoups of patients who have similar clinical features and provocation test response. MATERIALS AND METHODS: Twenty-one consecutive patients with pure vasospastic angina were studied. Six exercise tests were performed in the early morning, late morning, and late afternoon in consecutive days, and 2 hyperventilation tests and 2 cold pressor tests in the early morning. Circadian distribution and types of angina(at rest, on physical activity or both) were evaluated by clinical history, clinical records and ambulatory ECG recordings during admission and follow-up periods(mean 19+/-9 months). RESULTS: Three patterns of circadian distribution of anginal attacks were identified during all observation periods together(morning and night: MN n=, morning and afternoon or evening: M+/E n=, morning, night and afternoon and/or evening: MN+/E n=1). Exercise test was positive in 36%(40/111) without circadian variation, hyperventilation test in 66%(23/35) and cold pressor test in 6%(2/33). Neither hyperventilation test nor cold pressor test was related to circadian patterns, types or activity of angina, or numbers of spastic artery. But positive exercise test increased significantly in patients with angina on physical activity(43% vs 21%, p<0.05), high activity(57% vs 18%, p<0.01), multivessel spasm(50% vs 27%, p<0.05 ) and circadian patterns of M+/E and MN+/E(29%, 55% vs 4%, p<0.05, p<0.01). All patients with MN had rest angina and single vessel spasm. All 6 patients with M+/E had angina both at rest and on physical activity and 5 single vessel spasm. Eight of 11 patients with MN+/E had angina both at rest and on physical activity and 8 multivessel spasm. CONCLUSION: These findings suggest that hyperventilation test is highly sensitive in vasospastic angina without any relationship to clinical features, but exercise test response is related well to circadian patterns of angina attacks which are associated with characteristic clinical features.

BACKGROUND: Although several kinds of treatment methods(destructive therapy, immunotherapy, etc) for plane warts have been attempted but there have been no entirely satisfactory treatments, because the plane wants are seen to recur frequently. OBJECTIVE: This study was aimed to evaluate the combination therapy of griseofulvin and immunotherapy(dinitrochlorobenzene=DNCB, diphenylcycloprope none=DPCP) on plane warts. METHOD: Sixteen patients(age range, 9 to 41; mean age, 21.8 years) with VPJ were treated with the combination therapy with griseofulvin(500mg/day) and single contact immunotherapy(DNCB or DPCP).

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

We describe an 18-year-old male with generalized pruritic, tense annular or polycyalic blistera on normal-appearing skin or erythematous bases. Histopathological fmdings of an iatact early blistering showed subepidermal blistering and papillary neutrophilic gnicroabscesses. A direct immunofluctescent study of a section from the skin adjacent to a lesioti revealed linear deposits of IgA at the dermoepidermal junction. There were no deposits of IgG, lgM, or C3. In 1.0M NaC1 eplit skin, IgA was found to be bound linearly on the epidermal roof. The patient respmded weIl to eteroid and dapsone therapy.

Contemporary cementing techniques improved the longevity of the cemented total hip replacement. The mechanical strength of acrylic bone cement can be changed by different handling techniques with reduction of the porosity of acrylic bone cement. The greatest improvement of the mechanical properties with reducing the porosity is that of the fatigue strength. We investigated the mechanical properties of the specimens of high viscosity, Palacos R(Merk, Darmstadt, FRG) bone cement with two mixing methods, hand and vacuum mixing. Vacuum mixing improved the ultimate tensile strength by 22.4% compared to hand mixing in previous study. For the uniaxial tension fatigue test, the specimens were cyclically loaded at a maximum stress of 25 MPa at a frequency of 2.5 Hz and to investigate the porosity, scanning electromicroscopic examination was taken in each hand mixed and vacuum mixed specimens. Scanning electromicrogram showed the vacuum mixed specimens to be the more uniform and free of small voids compared with the hand mixed specimens. The results of the fatigue test were analized using Weibull distribution of survival probability, the average number of cycles to failure was 1459±924 cycles in hand mixed specimens, in vacuum mixed specimens, 21491±14956 cycles. The average fatigue life of the vacuum mixed specimens was 15 times loanger than that of the hand mixed specimens by Weibull mean, this differene exists stastically within 95% confidence interval. We could suggest vacuum mixing technique as a method eliminating porosity in a chilled acrylic bone cement and thereby markedly improving the mechanical properties. In cemented joint replacement surgery, a vacuum mixing technique are recommended as a method of preparation of acrylic bone cement

OBJECTIVES: Thyroid cancer patients may experience emotional distress during cancer treatment including surgical operation and radioactive iodine treatment. The aims of this prospective study were to investigate changes of anxiety and depressive symptoms in patients with differentiated thyroid cancer(DTC) under preoperative, postoperative and short-term hypothyroidism state. METHODS: Using the Hospital Anxiety and Depression scale(HAD) and the Distress Thermometer, we sequentially assessed the levels of anxiety, depression and distress in 41 DTC patients at 3 time points such as preoperative state, postoperative state and short-term hypothyroidism state. RESULTS: The HAD-anxiety score was significantly higher in preoperative state(6.93+/-3.97) than postoperative state(4.22+/-2.92) and short-term hypothyroidism state(4.93+/-3.64). Any other significant change in depression or distress thermometer score was not observed. Especially, difference of HADS score between the distress and none-distress groups was significant in preoperative state and post-operative state, but the difference become not significant in the short-term hypothyroidism state. CONCLUSIONS: Induced thyroid hormone deficiency during cancer treatment does not significantly affect emotional distress in patient with DTC. Anxiety and depression in these patients may be associated with distress of the patient before active cancer treatment.

BACKGROUND: Pneumoperitoneum for laparoscopic cholecystectomy induces prompt hemodynamic changes. The rapid onset of these changes suggests a neurohumoral response. The present study investigated the effects of pneumoperitoneum on plasma catecholamines and vasopressin during laparoscopic cholecystectomy. METHODS: We studied 18 healthy patients under general anesthesia using a isoflurane and nitrous oxide (50%). In our study, nine patients were selected for Group LC; they underwent the laparoscopic cholecystectomy. The remaining nine patients constituting Group OS served as the control, and underwent minor orthopedic surgery. Venous blood samples were collected 10 minutes after the induction of anesthesia, as well as 10 minutes after the insufflation of pneumoperitoneum or skin incision, and 10 minutes after desufflation of pneumoperitoneum or skin closure. Plasma vasopressin was measured using a radioimmunoassay method. Plasma epinephrine and norepinephrine were measured using the method of high-performance liquid chromatography. RESULTS: In Group LC, the plasma concentration of vasopressin increased remarkably from 2.1 pg/ml to 70.7 pg/ml after insufflation of pneumoperitoneum, and declined to 18.3 pg/ml after desufflation (P < 0.05). Plasma concentrations of epinephrine and norepinephrine also increased significantly after insufflation of pneumoperitoneum (P < 0.05). In Group OS, however, plasma concentrations of vasopressin, epinephrine, and norepinephrine remained stable throughout the operation. CONCLUSIONS: The pneumoperitoneum resulted in a substantial increase of plasma concentrations of vasopressin as well as a signifiant increase in the plasma concentration of epinephrine and norepinephrine during laparoscopic cholecystectomy.
