Rotator cuff tear is a common reason for shoulder pain. Although the surgical technique of rotator cuff repair is developing, high retear rate requires additional supplementary methods. Among these supplementary methods, as a kind of biologic augmentation, platelet-rich plasma (PRP) has been spotlighted and has recently been studied by many researchers. PRP, a concentrate of platelet extract obtained from whole blood, contains numerous growth factors. As this is known to play an important role in the tissue recovery process, it had been used for research in a variety of fields including orthopedics. Use of PRP has been attempted in surgical treatments of rotator cuff tear for better results; however, only a few large-scale research studies on the effect of PRP have been reported. Clinical results of each study are also variable. Therefore research using large-scale randomized, double-blind trials should be conducted in order to prove the application range, safety, and clinical effects of PRP.

The hemolytic uremic syndrome consists of microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia following a prodromal illness of gastroenteritis or upper respiratory infection. Sometimes, the syndrome can present in a dramatic fashion with severe abdominal pain and signs of intestinal obstruction, suggesting an intussusception or acute surgical crisis. A 2-year-old girl with a 3-day history of several episodes of bloody-mucoid diarrhea and severe abdominal pain was admitted under suspicion of intussusception. Her symptoms started 4 days after eating a pork and X-ray revealed the distended small bowel without a large bowel gas pattern. Colitis without perforation was found by abdominal ultrasonogram and sigmoidoscope. Unfortunately, she became pallor, puffy, and oliguric 7 days later. Clues to the diagnosis of hemolytic uremic syndrome in the early stages of the acute illness were oliguria, abnormal peripheral blood smear, anemia despite dehydration, and proteinuria. The onset is usually preceded by symptoms of gastroenteritis, such as fever, vomiting, abdominal pain, and bloody diarrhea. This is followed in 5 to 10 days by a sudden onset of pallor, irritability, weakness, lethargy, and oliguria. The majority of patients recover normal renal function with aggressive management of the acute renal failure. Careful medical management of the hematologic and renal manifestations, in conjunction with early and frequent peritoneal dialysis, offers the best chance of recovery from the acute phase. The present patient was recovered by apropriate fluid and electrolyte management, transfusions of packed RBCs, fresh frozen plasma, and early application of peritoneal dialysis.

Due to rapid industrialization and economic development, the occupational diseases have appeared as one of the social problems in Korea. Up until now little has been known about the prevalence rate, predisposing factor and symptomatology the occupational disease due to localized vibration in Korea. The researcher intends to investigate the prevalence rate and affecting factors of the occupational disease due to localized vibration among rock-drillers in the anthracite mines. A total of 135 rock-drillers were interviewed and examined from May 15th to 31th, 1980. The results were revealed as follows; 1. The prevalence rate of the vibration syndrome among rock-drillers was 12.6%. 2. The latent period of the vibration syndrome was 6.8% years. 3. The prevalence rate of the vibration syndrome was not significantly different between smokers and non-smokers. 4. With the increase of total vibration exposure time, the prevalence rate of the vibration syndrome increased also. 5. The average vibration sensation threshold was high (6.4dB) in stage 1 of the vibration syndrome and low (-0.6dB) in stage 0. 6. The average pain sensation threshold was high (4.4g) in stage 1 of the vibration syndrome and low (2.5g) in stage 0.

Extracapsular cataract extraction with posterior chamber intraocular lens in 24 eyes of 24 diabetics. With and without diabetic retinopathy, were followed up postoperatively for an average of 14 months to determine the incidence of diabetic retinopathy, the final visual acuity and factors predictive of progression of retinopathy and final visual acuity. Overall, retinopathy progressed in 52% of operated-on eyes. Cataract extraction was highly associated with progression of diabetic retinopathy. Women had a significantly increased risk of progression of retinopathy in the operated-on eye compared to men. Visual acuity improved in 22 of 24 orerated-on eyes : however, only 11 eyes achieved a visual acuity of 0.5 or better and only 7 eyes achieved a visual acuity of 0.7 or better. Patients treated with oral hypoglycemic agents had a worse visual prognosis than those treated with insulin. The prognosis of patients with diabetic retinopathy about to undergo cataract surgery, even extracapsular cataract extraction with placement of a posterior chamber lens, is guarded.
