BACKGROUND: To assess the incidence of venous thromboembolism (VTE) following shoulder surgery and to evaluate the role of postoperative duplex ultrasonography. METHODS: The study comprised a total of 224 patients who underwent shoulder surgery, including 180 shoulder arthroscopic surgeries, 28 shoulder arthroplasties, and 16 plate fixations for proximal humerus fracture between January 2014 and December 2014. The mean age of patients was 59.0 years, and there were 81 men and 143 women. Clinical data, including body mass index, blood tests, metabolic work-up for liver and renal function, previous, and present medical history, were evaluated. Duplex ultrasonography in the operative arm was performed on 2 to 4 days after surgery. RESULTS: The overall incidence of VTE following shoulder surgery was 0.45% (1/224). One patient with open reduction and plate fixation for proximal humerus fracture had asymptomatic deep vein thrombosis that showed complete remission after anticoagulant medication during a 2-month period. Four patients had asymptomatic superficial cephalic vein thrombosis and complete remission without any treatment. There was no case of pulmonary embolism. CONCLUSIONS: The incidence of VTE following shoulder surgery was extremely low in Asians. Duplex ultrasonography may be not considered a routine follow-up of shoulder surgery and can be selectively performed in high-risk or symptomatic patients for VTE.

One hundred eighty infants with oxygen therapy who were under 2,500gm birth weight or under 37 weeks of gestational age, were examined between January 1990 and November 1992. We performed clnical analysis and results were as follows. 1) Fifty six infants (31.1%) were diagnosed as retinopathy of prematurity. 2) The first examination was performed at 2.5 weeks of life on average, and the retinopathy of prematurity was diagnosed at 3.8 weeks on average. 3) The incidence of retinopathy of prematurity was highly associated with low birth weight (< or =1,890 gm), low gestational age ( < or =33.1 weeks), and high oxygen concentration with long duration (FiO2> or =0.4 over 1 week)(P<0.005). 4) Other associated risk factors were idiopathic respiratory distress syndrome, anemia, neonatal hypoxia and sepsis.

PURPOSE: To determine clinical outcomes of mini Monoka silicone monocanalicular lacrimal stent (from now, mini Monoka stent) in canalicular injury. METHODS: From June 1996 to December 2001, mini Monoka stent was used in 70 eyes(77 canaliculi) of superior, inferior and bicanalicular injury. Mini Monoka stent was shortened about 20 mm with round tip and intubated. Punctal fixation suture was not done. RESULTS: The mean follow-up period was 7.9+/-1.0 months (4-12 months). The outcome of our repair was judged by the existence of epiphora, dye disappearance test, probing and irrigation. In 57 eyes (81.4%), there was no epiphora. In 11 eyes (15.7%), epiphora was developed only after certain stimuli. In 2 eyes (2.9%), there was epiphora at all times. Postoperative complications were premature stent loss 6 eyes (8.6%), conjunctival injection 3 eyes (3.9%). CONCLUSIONS: The intubation of mini Monoka stent for the lacerated canaliculus is the simply operative procedure in the outpatient department. The shortening of mini Monoka stent made this procedure easier. Despite no punctal fixation suture, the occurrence rate of the premature stent loss was not higher than that for published reports of mini Monoka stent.

MicroRNA polymorphisms may be associated with carcinogenesis or immunopathogenesis of infection. We evaluated whether the mircoRNA-604 (miR-604) polymorphism can affect the persistence of hepatitis B virus (HBV) infection, and the development to hepatocellular carcinoma (HCC) in patients with chronic HBV infection. A total of 1,439 subjects, who have either past or present HBV infection, were enrolled and divided into four groups (spontaneous recovery, chronic HBV carrier without cirrhosis, liver cirrhosis and HCC). We genotyped the precursor miR-604 genome region polymorphism. The CC genotype of miR-604 rs2368392 was most frequently observed and T allele frequency was 0.326 in all study subjects. The HBV persistence after infection was higher in those subjects with miR-604 T allele (P=0.05 in a co-dominant and dominant model), which implied that the patients with miR-604 T allele may have a higher risk for HBV chronicity. In contrast, there was a higher rate of the miR-604 T allele in the chronic carrier without HCC patients, compared to those of the HCC patients (P=0.03 in a co-dominant model, P=0.02 in a recessive model). The T allele at miR-604 rs2368392 may be a risk allele for the chronicity of HBV infection, but may be a protective allele for the progression to HCC in chronic HBV carriers.

PURPOSE: To evaluate the incidence of persistent diplopia and enophthalmos and possible risk factors leading to their occurrence in patients who had orbital blowout fracture repair. METHODS: We retrospectively evaluated clinical features in 76 eyes of 76 patients with orbital blowout fracture, who were repaired surgically after its diagnosis from March 1995 to November 2001. We analysed the relationship between persistent diplopia and enophthalmos after reconstruction and timing of surgery, patient age, fracture location, fracture size and alloplast material. RESULTS: Postoperatively, 11 patients (22.9%) expirienced diplopia and enophthalmos persisted in 11 (28.2%) patients. Timing of surgery, patient age, fracture location, fracture size was found to be significant for the development of postoperative diplopia but alloplast material was not significant for the development of postoperative diplopia (p>0.05). Timing of surgery and fracture size was found to be significant for the development of postoperative enophthalmos but patient age, fracture location and alloplast material was not significant for the development of postoperative enophthalmos (p>0.05). CONCLUSIONS: We believe that timing of surgery is important prognostic factor that decreases the incidence of persistent diplopia and enophthalmos after surgical repair of blowout fracture. In addition, this study will provide important prognostic informations that can be of benefit to both patients and surgeon in performing surgical repair of blowout fracture.

HLA antigen expression can show close relationship with some kinds of tumor cell immunologically. We investigated the relationship between the grade of bladder transitional cell carcinoma and HLA-DR expression to demonstrate the prognostic significance. Paraffin-embedded samples from 25 human transitional cell carcinoma cases were examined for the expression of MHC class R antigen with monoclonal antibody directed against HLA-DR using immunohistochemical methods. The tumors were classified according to the Ash grading system and the degree of the peritumoral mononuclear infiltrates. Both diffuse cytoplasmic and membrane HLA-DR staining were observed in 6 or 17 low grade (Grade I, II) tumors. All 8 high grade (Grade II IV)transitional cell carcinoma exhibited negative staining for HLA-DR antigen. Apart from the relatively high incidence of the positive expression of HLA-DR in low grade tumors, no clear statistical relationship was found between the expression or HLA antigens and the tumor grade. From these results, it may be suggested that the low grade transitional cell carcinoma shows a high incidence of HLA-DR expression and prognostic significance induced by immune response; T cell-mediated immune response against TCC proliferation is evoked. But the significance of these findings remains speculative at present. Therefore, further study should be performed to demonstrate the prognostic importance of HLA-DR expression in transitional cell carcinoma of the bladder.

PURPOSE: To evaluate the surgical results and complications in patients with blepharoptosis who underwent frontalis suspension using a silicone rod. METHODS: A total of 31 lids of 23 patients with blepharoptosis and poor levator function underwent a pentagon-shaped loop silicone sling surgery in which six skin incisions were made. Eighteen patients had congenital ptosis, two blepharophimosis-ptosis syndrome, two blepharoptosis with superior rectus muscle weakness, and one third nerve palsy. RESULTS: With a mean age of 14 years and a mean follow-up of 16 months, good-to-excellent lid height was achieved in 27 lids (87%) of 20 patients and poor results with undercorrection in 4 lids (13%) of 3 patients. Three of the 4 lids with poor results had reoperation and satisfactory results were achieved. Transient exposure keratitis occurred postoperatively in 7 lids (23%) and persistent exposure keratitis in 2 lids (6%). During the follow-up period, extrusion of the sling and infection did not occur; ptosis recurred in 4 lids (13%). CONCLUSIONS: Silicone rod can be adjusted easily after frontalis suspension, but it needs to pay close attention because the string can be broken during the operation or follow-up period. It is considered that additional follow-ups for a long-term recurrence rate of ptosis are necessary and sufficient explanation to the patients and family and their understanding are need.
