Reverse total shoulder arthroplasty has been performed with promising results in rotator cuff tear arthropathy. However, the global complication of the reverse total shoulder arthroplasty is relatively higher than that of the conventional total shoulder arthroplasty. Neurologic complications after reverse total shoulder arthroplasty are rare but there are sometimes remaining sequelae. The cause of the neurologic complication is multifactorial, including arm traction, position and the design of the implant. Most cases of neurologic palsy following reverse total shoulder arthroplasty occur in the axillary nerve and the radial nerve. The authors report on a case of a 71-year-old man with isolated musculocutaneous nerve palsy after reveres total shoulder arthroplasty with related literature.

Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

The authors analysed 43 cases of intraocular foreign body patients who were treated at the Ophthalmic Department of Busan National University Hospital, during a 10-year period. Follow up study was done for all cases of Patient at least 6 months or more after operation. And the author studied several factors which influence the prognosis of Intraocular Foreign Body. The results as follows: 1. The incidence of I.O.F. waS prevalent in young male adult 20-30 years of age, and their large number of cases were magnetic properties. 2. The larger the size of foreign body and the deeper the location of foreign body, the worse the prognosis of final visual acuity was. 3. Time between admission and operation after injury did not influence the prognosis of final visual acuity.

PURPOSE: To identify the changes of bony landmarks with rotation and to compare the reliability and accuracy of Perdriolle's method before and after training on the exact bony landmarks. MATERIALS AND METHODS: Simple A-P radiographs were taken with rotation from 5 degree to 50 degree at 5 degree interval using 10 dry human vertebrae (2 sets of T3, T6, T9 8 L3) with no bony abnormality. Axial rotation was measured before and after training on the exact bony landmarks by three observers, twice for each radiographs. Repeated measures of ANOVA were used for inter- < intraobserver variance and regression analysis for root mean square error and deviation of differences. RESULTS: Mamillary process, inner margin of lamina, proximal and distal costovertebral joints, upper margin of concave pedicle and tip of the transverse process on the convex side confused the exact outline of the pedicle, while neural foraminal margin was helpful in identifying the location of the indistinct convex pedicle and concave vertebral border. Of the 660 measurements before and after training 372 and 397 errors were made, respectively, of which 88.9% and 88.5% were within +/-5 degree(P > 0.05). Incidence of error greater than 5 degree was high at upper thoracic vertebra and 20 degree-40 degree of rotation regardless of training. The effects of training, however, was greatest at T3 and 20 degree-40 degree of rotation. Inter- < intraobserver variance was diminished at T3 and at the rotation between 20 degree-40 degree after training. CONCLUSIONS: We could conclude that training on the exact bony landmarks did not reduce the overall error incidence. Accuracy and reliability, however, was increased at T3 after training and the efficacy of training was more evident in moderate vertebral rotation than in small or large vertebral rotation.

The authors studied the retinal vascular patterns of human eye suffered from complicated endophthalmitis following by perforating injury and corneal ulcer. The technique of preparing slides to study the retinal vascular patterns were same as previously noted Part I report. A lot of microorganisms, such as cocci, bacilli and fungi are found in the inflamed foci(with or without filaments) around the retinal vessels unless the vessels were completely occluded. Focal and diffuse exudative vasculitis is related to the species of microorganisms and cbserved stage but almost all retinal vessel waIls show diffuse loss of perivascular argyrophilic fibers, socalled "moth eaten" appearance. In the later stage of vasculitis microorganisms are not found in the inflamed focus("punched out" lesion) of the occluded vessels which show as "bark-stripped-dead tree" appearance in reticulin stain.

The authors observed retinal vascular patterns of the blind eyes surgically removed on account of pain, high intraocular pressure and global rupture by injury. Material for the study was 10 eyes which were 4 eyes of long standing absolute glaucoma, late stage of chronic simple glaucoma (3 eyes) and chronic angle closure glaucoma (1 eye). aphakic glaucoma (1 eye) and an eye of chronic simple glaucoma with traumatic global rupture. The technique of preparation of the slides was made of flat preparations of retinal vessels that all nonvascular components were digested with tris-buffered 3% trypsin solution and stained with PAS-hematoxylin and Wilder's reticulin stain. RESULTS OBTAINED AS FOLLOWS; 1. it is possible that diffuse acellularity (predominant loss of endothelium) in the capillaries of the equatorial and posterior portion of retina results from the arterial occlusion. 2. Solitary microaneurysm in the peripheral retinal capillary was found in the early stage and numerous saccular and fusiform aneurysms (rows of bead-like aneurysms) on the venules, and arteriolar and venular capillaries are related to the degree and duration of the venous occlusion. 3. The majority have had venous occlusion initially, on which distal venule there are found rows of bead-like outpouchings, and the occlusive arterioles show fibrinous appearence, accllularity and increasing PAS staining. 4. It is possible that abnormal A-V shunts and venous collaterals result from the venous occlusion and rows of bead-like microaneuysms in the capillaries will be switched over to shunts and collaterals.

The long term administration of anti-convulsants on children with convulsive disorders may cause osteomalacia, depending on the dosage, duration, type and combination of anti-convulsants administred. Fifteen children, comprising 10 male and 5 female, dignosed with convulsive disorders and administered with phenobarbital for a long term period of more than 9 months but less than 84 months and 15 healthy children of a similar age-group were selected for the investigation the density of she spinal backbone of each individual was measured by means of the "QDR-2000 X-ray bone densitometer's (made by Hologic company) which uses the double energy X-ray absorption technique. The levels of serum calcium, phosphrus and alkaline phosphatase for each child were also measured for comparative analysis. The results were as follows: 1) The mean bone density for the healthy group of chlidren was 0.69+/-0.09g/cm(2) and that for the group of children administered with phenobarbital was 0.59+/-0.07cm(2) indicating a significant decrease in density for the latter group (p<0.05). 2) As for the relationship between the duration of phenonbarbital and the decrease in bone mineral density, 5 of 6 patients(83%) administered with phenobarbital for more than 4 years showed a decrease in bone mineral density and 5 of 9 patients (56%) administered with phenobarbital for less than 4 years showed a decrease in bone mineral density. 3) the mean vitamin D level for the healthy group of chlidren was 26.8+/-2.5pg/ml indicating a significant decrease in vitamin D3 level for this group(p<0.05). 4) The mean serum alkaline phospatase evel for the health group of children was 240+/-50u/L and 462+/-110u/L for those administered with phenobarbital. This indicate a significant increase in ALP for phenobarbital group(p<0.05). 5) The posphorus and calcium levels were within the normal range for all the groups of children.

Nesidioblastosis is characterized by a diffuse proliferation of islet cells arising from pancreatic ducts and is the most common cause of hyperinsulinemic hypoglycemia in newborns and infantile. It is exceedingly rare in adults and no concensus regarding its diagnosis and management is available. We herein describe an elderly man with fasting hypoglycemia, inappropriate insulin hypersecretion. And pathologic examination of his pancreas revealed the characteristic finding of nesidioblastosis confirmed by immunohistochemical stain.
