Repeated throwing of baseballs by juvenile pitchers is known to cause damages to bone and cartilage as well as soft tissue in the involved upper extremity. Authors present 4 cases of osteochondral lesion at capitellum of the humerus as a result of repeated insult by throwing baseballs in the juvenile pitchers. Pain and limitation of extension of the affected elbow were the commonest symptoms. Cystic change or osteochondral loose body was found on plain X-ray. Treatment consisted of rest and analgesic administration in the patient who has no loose body, while in case of having loose body it was removed surgically without further treatment to the crater. In spite of the rapid relief of the pain by these treatment, limitation of extension persisted for considerable period of time. It is strongly suggested not to overlook elbow pain in young adolescent whose bone is still growing and who can hardly withstand repeated insult to prevent the development of baseball elbow.

The effect of nicardipine was investigated on hypertension due to raised intracranial pressure, pressor response of alpha-adrenoceptor agonists in the dissected thoracic aorta. Intracerebroventricular(icv) and intravenous(iv) nicardipine produced dose-dependent depressor response and bradycardiac effect, especially marked response was observed following iv injection. The pressor response to raised intracranial pressures was potentiated following iv injection of 50 microgram/kg nicardipine but was markedly inhibited following iv 100 microgram/kg injection, and was not affected following icv 50 microgram/kg administration but was markedly inhibited following icv administration of 100-200 microgram/kg nicardipine. The nicardipine inhibited contractile effect of KCI 35 mM in a dose-dependent fashion but did not affect that of Ne and ME. These data suggest that nicardipine caused hypotensive effect by blocking calcium influx in the peripheral vessels and that direct effect of nicardipine on central nervous system involves the hypotensive action. Conclusively, the inhibitory effect of nicardipine on the pressor response to the intracranial pressure elevation may be induced by these two mechanisms.

Ulcerative colitis is diffuse inflammatory condition at mucosal lining of the colon & rectum and rare in Korea but there are no pathognomonic features or specific diagnostic tests. However, recently the diagnostic methods for ulcerative colitis are much developed and the incidence of ulcerative colitis is increased in Korea. Therefor, an analysis of 31 cases of ulcerative colitis which was diagnosed and treated in the department of the YeungNam University Hospital from May l983 to April 1991 was reviewed. The results were as following: 1) The sex distribution assumed a ratio of 1 to 2.1 and the age distribution was vqriable but the most prevalent age group was 5th decade(29.0%). 2) The most common clinical manifestations were abdominal pain & bloody diarrhea. 3) As to the extent of disease determined by the barium enema & endoscopy, rectum or rectosigmoid colon was involved in majority of the cases 22.6%, 41.9 (respectively). 4) Significant laboratory findings were elevated ESR, anemia, leukocytosis, hypoalbuminemia. 5) The endoscopic examination was performed in all 31 cases and showed sinificant findings such as hyperemia, mucosai edema, superficial ulceration & mucosal friability. 6) 23 of 26 cases treated by sulfasalazine medication showed improved, and 3 cases were improved by steriod medication and the surgical operation was indicated in 1 case.

Transfusion complications include ABO/Rh incompatibility, sepsis, febrile reaction, immunosuppression, and viral transmission. We experienced a case of anaphylactic reaction in a 40-year-old male scheduled for laminectomy. Anesthesia was induced by intravenous (I.V.) thiopental sodium and maintained with enflurane / N2O / oxygen. Vital signs were stable until 2 hours into surgery, when patient developed sudden profound hypotension (systolic pressure 60 mmHg) with tachycardia, skin flushing and bronchial wheezing shortly after infusion of only a few milliliters of 4th unit of whole blood. Blood transfusion was immediately stopped, anesthetic agents were discontinued, and 100% oxygen was administered. Rapid administration of I.V. fluids was begun and I.V. hydrocortisone along with pheniramine were administered. Patient was successfully treated and eventually discharged from the hospital. In conclusion, besides hemolytic transfusion reaction, anaphylactic transfusion reaction may cause severe hypotension. One should be aware of the potential for adverse effects including anaphylaxis, should recognize them immediately and treat them appropriately.

Cystic entrapment of infraspinatus branch of suprascapular nerve is a rare cause of shoulder pain with infraspinatus atrophy. We discuss the ultrasonographic diagnosis and ultrasonography- guided aspiration of the cyst as a treatment. Case: A 37-year-old, ship-yard laborer had experienced left shoulder discomfort and pain without trauma history. Physical examination showed profound selective atrophy of left infraspinatus muscle. Simple X-ray of shoulder showed normal findings. Electrodiagnostic examination revealed delayed motor latency of infraspinatus branch of suprascapular nerve and denervation potentials of infraspinatus muscle exclusively. Ultrasonographic finding showed 13.5X21.5 mm sized cystic mass around left infraspinatus notch. Ultrasonography-guided aspiration was done, and then electrical stimulation therapy and strengthening exercise of left shoulder were performed. Symptoms were improved. We report a rare case of cystic entrapment of infraspinatus branch of suprascapular nerve in a patient without traumatic insult.

BACKGROUND AND OBJECTIVES: Incidences of postoperative mucoceles of the frontal, ethmoid, or sphenoid sinuses are currently on the rise. The clinical rogression of the postoperative mucoceles in the frontal, ethmoid, or sphenoid sinuses are different from that of the maxillary mucoceles. In this study, we investigated the clinical patterns and treatments of postoperative mucoceles, which have developed in the frontal, ethmoid, or sphenoid sinuses. MATERIALS AND METHODS: Between June,1994 and August, 2005, twenty-six patients with thirty postoperative mucoceles were treated surgically. They had a previous history of operation and incidences of maxillary mucoceles were excluded from the study. A review of the clinical subjects were performed using their clinical records and radiological findings. RESULTS: The locations of the postoperative mucoceles were, in the order of frequency, the ethmoid, frontal, fronto-ethmoid, spheno- ethmoid, sphenoid, and fronto-ethmoidsphenoid sinus. Postoperative mucoceles occurs mostly in the form of ophthalmic symptoms and headache. The ophthalmic manifestations were different between the anterior, posterior and the antero-posterior mucocele group. The mean duration until diagnosed as postoperative mucocele since the previous sinus surgery was 9.9 years, and endoscopic sinus surgeries and intranasal ethmoidectomies with Caldwell-Luc operations were the majority among previous surgeries. Most postoperative mucoceles could be successfully treated with an endoscopic marsupialization. CONCLUSION: Frontal, ethmoid, or sphenoid postoperative mucoceles developed mostly on the ethmoid sinus and occurs mainly in the form of ophthalmic symptoms. Most postoperative mucoceles were successfully treated with an endoscopic marsupialization.
