Recurrent posterior shoulder instability is a debilitating condition that is relatively uncommon, but its diagnosis in young adults is increasing in frequency. Several predisposing factors for this condition have been identified, such as the presence of an abnormal joint surface orientation, an osteochondral fracture of the humeral head or glenoid cavity, and a postero-inferior capsuloligamentary deficit, but their relative importance remains poorly understood. Whilst, conservative treatment is effective in cases of hyperlaxity or in the absence of bone abnormality, failure of conservative treatment means that open or arthroscopic surgery is required. In general, soft-tissue reconstructions are carried out in cases of capsulolabral lesions in which bone anatomy is normal, whereas bone grafts have been required in cases where posterior bony Bankart lesions, glenoid defects, or posterior glenoid dysplasia are present. However, a consensus on the exact management of posterior shoulder instability is yet to be reached, and published studies are few with weak evidence. In our study, we report the reconstruction of the glenoid using iliac bone graft in a patient suffering recurrent posterior shoulder instability with severe glenoid bone defect.

BACKGROUND: Nausea, vomiting are among the most common postoperative complaints. We compared the effects of dexamethasone with or without propofol to the effects of conventional regimen consisting of enflurane-N2O in the prevention of postoperative nausea and vomiting. METHODS: Eighty healthy children, aged 3~14 yr, undergoing elective tonsillectomy were alldegrees Cated randomly to receive either 67% nitrous oxide and 1.5~2.0% enflurane or 67% nitrous oxide and propofol infusion 6~10 mg/kg/hr for maintenance of anesthesia. Dexamethasone 150 microgram/kg(maximum dose 8mg) or placebo was administered intrvenously(IV) in a double-blinded fashion before surgery. RESULTS: Dexamethasone reduced the overall incidence of vomiting from 45%(control) to 10%, Propofol also reduced from 45% to 15%. Combination of propofol anesthesia and dexamethasone administration reduced from 45% to 10%. CONCLUSIONS: Dexamethasone and propofol markedly decreased vomiting in healthy children after elective tonsillectomy.

BACKGROUND: Reactive oxygen species (ROS) induce lipid peroxidation and tissue damage in the isolated rabbit thoracic aorta. The aim of this study was to explore the influence of the propofol and midazolam against ROS in the isolated rabbit thoracic aortic endothelium. METHODS: Eighteen white male rabbits (weighing 2.0-2.5 kg) were used. The thoracic aorta was dissected free and cut into rings (3-4 mm) and then suspended in a organ bath filled with 10 ml Krebs solution bubbled with 5% CO2 95% O2 at 37 degrees C. Aortic rings were then equilibrated for 90 min, and a resting tension of 1.5 g was applied. The Krebs solution was changed every 15 min. Isometric tension was recorded with transducer coupled to a data acqusition system (Biopac Inc. USA) on a PC. After precontraction with norepinephrine (NE, 10(-6)M), changes in tension were measured following the cumulative administration of acetylcholine (ACh 3x10(-7), 10(-6) and 3x10(-6)M) and nitroglycerin (NTG, 10(-5)M). Data are expressed as percentage of the 10 5 M NTG-induced relaxation (ACh/NTG). The ACh/NTG, before and after electrolysis were defined as the control and the experimental groups. The aortic rings were pretreated with propofol (3x10(-5), 10(-4), 3x10(-4) and 5.7x10(-4) M, n = 8, 10, 15, 13), midazolam (10(-4)M, n = 7), catalase (1,000 U/ml, n = 12), mannitol (3x10(-4)M, n = 5) or not pretreated group (Free, n = 6). After 30 minutes, the aortic rings were exposed to ROS generated by electrolysis (DC 9 V, 20 mA, aortic rings 1 cm away from electrode) in Krebs solution for 2 minutes, which was then changed for physiologic buffered salt solution. The aortic rings were precontracted with NE and vasorelaxation was induced with ACh and NTG at the above mentioned concentrations. RESULTS: Propofol produced vasorelaxation of NE-precontracted thoracic aorta in a dose-dependent fashion in all groups of propofol (3x10(-5), 10(-4), 3x10(-4) and 5.7x10(-4)M) even after ROS attack (P < 0.05 vs control value). Catalase produced vasorelaxation after ROS attack (P < 0.05 vs control value).On the other hand, ACh-induced significant endothelium-dependent vasorelaxation were not observed in the midazolam or mannitol pretreated group or the non-pretreated group (P <0.05 vs control group). CONCLUSIONS: These findings suggest that propofol and catalase preserve ACh induced endothelium-dependent vasorelaxation and that propofol has a concentration dependent ROS scavenging effect like catalase.

The case was described of a 43 year old male who developed burns of the both shins as a result of handling wet cement. After wet cement was spilled into the rubber boots he was wearing, he experienced painful erythema of both lower legs. Several weeks later, medical examination revealed dirty and granulated ulceration of the both shins. The largest ulcer, about 18 by 10 centimeters, was located on the anterior aspect of left lower leg. We coneluded that this skin problem resulted from the ertreme alkalinity of calcium hydroxide in wet cement, combined with the effects of pressure and occlusion against the skin.

Plsama and urinary Mg were measured in relation to EKG change in 24 patients with liver cirrhosis, and summarized as below. 1. Plasma albumin and Ca were below normal, however Na, K, and Mg level were in the lower limit of normal. 2. Abnormal EKG findings were QT prolongation, ST elevation, peaked T, low T, ST depression and U wave in the order of frequency. 3. Coefficient of correlation between plasma Mg and QT prolongation was -0.5 compared with that of Ca-0.28. 4. Mg depletion was moderately correlated with plasma albumin (r=0.59). 5. Marked urinary Mg excretion in the presence of normal plasma Mg suggest that plasma Mg level poorly reflect total Mg depletion.
