1.Iliac Bone Graft for Recurrent Posterior Shoulder Instability with Glenoid Bone Defect.
Clinics in Shoulder and Elbow 2014;17(4):190-193
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.

A 43-year-old woman presented with numerous cutaneous neurofibromas, limited to the left anterior chest(T2-3) and the right lower back(L1-2). These had been present for 10 years. Neither cafe-au-lait spot, intertriginous freckle, nor Lisch nodule was found. The family history was negative for neurofibromatosis. Biopsy specimens showed circumscribed, nonencapsulated neurofibromas. The present case was a rare form of bilateral segmental neurofibromatosis in that while most of the reported cases involved the same dermatome bilaterally, she had bilaterally different dermatomal neurofibromas.

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.

8.Acute Ulcerative Contact Dermatitis from Ready Mixed Conerete.
Korean Journal of Occupational and Environmental Medicine 1995;7(1):191-194
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.

BACKGROUND: We performed electrical cardioversion for the patients with chormic nonvalvular atrial fibrillation under the transesophageal echocardiographic guidance after anticoagulation to evaluate the safety of this procedure and the effects of electrical cardioversion on the atrial function. METHODS: After anticoagulation therapy with coumadine for three weeks, we tried chemical cardioversion with amiodarone first. Failed cases were included in this study. Pre-cardioversion transesophageal echocardiographic parameters were measured after exclusion of thrombi. After sedation with intravenous midazolam, direct-current cardioversion was done with the transesophageal echocardiographic probe in situ. Immediately after sinus conversion, we measured echocardiographic parameters again. Spontaneous echo contrast(SEC), left atrial appendage flow velocity, pulmonary vein flow velocity and time-velocity-integral(TVI), transmitral flow velocity, TVI and deceleration time were measured. All patients were anticoagulated for at least 4 weeks after cardiovesion. RESULTS: The total number of patients was forty one(24 males, 17 females) with the mean age of 58 years(range : 39-70). Mean duration of atrial fibrillation was 65 months(range : 1-360). Hypertension(12), dilated cardiomyopathy(10), cerebrovascular accidents(6), ischemic heart disease(2) and chronic lung disease(1) were associated. There were no complications. SEC increased or newly appeared in 18(43.9%) patients after sinus conversion. The left atrial appendage emptying velocity decreased(32.8+/-17.4 vs. 22.1+/-11.4cm/sec, p=0.020) and systolic TVI of both upper pulmonic vein increased significantly after sinus conversion. In two cases, early systolic forward flow(S1) of pulmonic vein appeared after sinus conversion. Transmitral E velocity decreased(86.9+/-28.8 vs. 76.3+/-30.6cm/sec, p=0.006) and the deceleration time increased(164+/-49 vs. 206+/-53msec, p=0.000) after sinus conversion. Transmitral A velocity was still low(34.9+/-19.5cm/sec) and E/A ratio was high(2.6+/-1.4) immediately after sinus conversion. CONCLUSION: After appropriate anticoagulation therapy and exclusion of left atrium and left atrial appindage thrombi with TEE we could perform electrical cardioversion safety without complications. The changes in transesophageal echocardiographic parameters after sinus conversion revealed the appearance of atrial mechanical activity in concordance with electrical activity. But these findings suggested atrial stunning or electromechanical dissociation which necessitates extended anticoagulation therapy until the full recovery of atrial mechanical function.
