PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

The present study was intended to examine the spectrum of radiographic patterns of the stomach associated withacute and chronic pancreatitis and their complications. Subjects served for the study consisted of 70 cases ofpancreatitis (36 cases in acute stage and 34 cases in chronic stage). Intramural and perigastic permeation ofextravasated pancreatic enzymes and secondary inflammatory reacation that follows are responsible for theardiographic change observed. 1. Generalized rugal thickening and particularly selective mucosal prominences ingreater curvature of body and antrum are characteristically seen in acute(14 of 36 cases

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

Arnold-Chirai malformation type II is congenital disorder which consists of downward displacement into upper cervical spinal canal of parts of the cerebellum, 4th ventricle, and medulla oblongata. We experienced two cases of Arnold-Chiari malformation with lumbar meningomyelocele, hydrocephalus. We confirmed the cases by brain C-T and report with brieft review of the lilterature.

The Dandy-Walker syndrome is a developmental disorders of the brain characterized by cystic deformity of the 4th ventricle and agensis of the cerebellar vermis. Other systemic anomalies and chromosomal abnormalities are associated with this syndrome. We are experienced a case in a 9 months old male infant who presented initially with frequent vomiting, low birth weight, On the physical examination, a prominent occiput, palpable mass below the right upper quadrant, pulmonary valve stenosis, congenital dislocation of the hips, ventral flexion of fingers, clubfoots and the rocker-bottom deformities of feet were present. On the chromosomal study, there were chromosomal polymorphisms in a thickened C-band of chromosome No. 1 by C-banding method. The brain CT revealed a large, thin-walled, low density mass of CSF without enhancement in the posterior fossa, showing upward displacement of cerebellar hemisphere with absent inferior vermis(or associated with dysplastic cerebellar hemisphere). A brief review of the related literatures were included in this report.

An one-day-old female patient was admitted due to marked abdominal distension, cyanosis, right upper quadrant mass, and respiratory failure since birth. We applied ventilator and supportive care immediatly. However, 4 days later, she was dead due to respiratory failure and hemorragic complication. The radiographic finding showed a huge intra-abdominal mass anterior to the intestine. Autopsy findings showed a huge single cystic tumor in the right lobe of the liver. The cysts were filled with sanguinous fluid. There wasn't any signs of necrosis or calcification. Microscopically, the tumor was well demarcated from the adjacent hepatic parenchyma. It consists of connective tissue with dilated lymphatics, vessels, and bile ducts.

Relapsing polychondritis is an uncommon disease manifested by episodes of progressive inflammation and destruction of cartilage. While the cause remains unknown, an autoimmune pathogenesis appears likely. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. The clinical course of patients may vary from a relatively benign illness free of clinically evident visceral involvement, to one of episodic or smoldering activity with variable intensity, to a f ulminant illness and death within months of diagnosis. Dapsone, corticosteroid and immunosuppressive agent remain the effective therapies. We have experienced a case of relapsing polychondritis and active pulmonary tuberculosis in a 69-year-old man. He suffered from arthralgia and swelling of joints for several months on the first admission and initially was diagnosed as pseudogout based on polyarthritis and chondrocalcinosis of right knee joint. During follow-up, chondritis of both auricles and nose, which was proved by the biosy of right auricle, and relapse of polyarthritis were developed. His spu tum smear for acid-fast bacillus was postive on the second admission. Then he was diagnosed as relapsing polychondritis and active pulmonary tuberculosis and has achieved improvement with medication of dapsone and antituberculosis drugs according to susceptability test during followed-up. Thus we report this case with literature review.

BACKGROUND: One of the most common side effects of antidepressant medication is orthostatic hypotension, which can be caused by impaired vasoconstriction. This study was designed to compare the inhibitory effects of antidepressants, including selective serotonin reuptake inhibitors (SSRIs), on the contractile responses to alpha1-adrenergic receptor activation and depolarization in isolated rat aorta. METHODS: Vascular rings were suspended for the measurement of isometric tension in a water-jacketed bath filled with Tyrode solution. After pretreatment with antidepressant for 20 min, vasoconstriction induced by norepinephrine (NE) or 35 mM K+ was measured and compared to the control response. RESULTS: Whereas trazodone and tricyclic antidepressants (TCAs) selectively inhibited NE-induced vasoconstriction, SSRIs inhibited depolarization-induced vasoconstriction more potently. The IC50 value of fluoxetine on depolarization- induced vasoconstriction was 3.29 microM, which is consistent with the previous results on L-type Ca2+ currents of cardiac myocyte. Moclobemide, a monoamine oxidase inhibitor, had no effect on vasoconstriction induced by either alpha- adrenergic receptor activation, or depolarization. CONCLUSION: These results suggest that SSRIs, different from TCAs and trazodone, have potent inhibitory actions to depolarization-induced contraction that may be due to blocking Ca2+ entry through L-type Ca2+ channel.
