PURPOSE: To evaluate the results of surgical treatment of autogenous cancellous bone grafting combined with threaded K-wire fixation for scaphoid nonunions. MATERIALS AND METHODS: We retrospectively reviewed the 13 patients with scaphoid nonunion, which was follow up at least 12 months from March 1999 to June 2003. According to the Mayo classification, two cases were type P (proximal third), eight cases were type W (waist) and three cases were type D (distal third). According to the Russe classification, eight cases showed horizontal oblique type, another two cases were transverse, and last three belonged to vertical oblique type. We assessed the radiologic bony union, correction of humpback deformity and lateral intrascaphoid angle and degenerative change of radioscaphoid joint, clinical results were evaluated using assessment of Maudsley. RESULTS: Radiologic union was obtained in all cases, mean time of union was 15.4 weeks (13~17.4 weeks), and there was no radiological evidence of postoperative humpback deformity, intercarpal instability, proximal osteonecrosis and degenerative changes. According to assessment of Maudsley, there were 7 excellent cases, 4 good cases, 1 fair case and 1 poor case among these 13 cases. The final clinical results were 11 excellent cases, 2 good case in the aspect of wrist pain and tenderness. All range of motion was satisfactory to patients except 4 cases (3 fair, 1 poor) and every patients could return to work except 1 poor case. CONCLUSION: The surgical treatment using a autogenous cancellous bone grafting combined with threaded K-wire fixation for scaphoid nonunion was a relatively straightforward technique, which provides simplicity, and high union rate.

PURPOSE: To evaluate the concentrations of commercially available ofloxacin 0.3%, levofloxacin 0.5%, and ciprofloxacin 0.3% topical ophthalmic solutions in human aqueous humor. METHODS: Patients scheduled to undergo phacoemulsification and posterior chamber lens insertion for treatment of cataract were enrolled in this prospective study. After informed consent was obtained, patients were randomized to receive 1 drop of ofloxacin 0.3%, levofloxacin 0.5%, or ciprofloxacin 0.3% topical ophthalmic solution 5 times at 1-hour intervals from 6pm one day before surgery and 3 further times at 5-min intervals immediately before surgery. After aspirating approximately 0.1 mL of aqueous fluid by paracentesis, surgery was commenced. We recorded the interval between the last drop and paracentesis. Specimens were stored at -70 degrees C until assayed by high-performance liquid chromatography. RESULTS: Thirty-four patients were enrolled. 14 male and 19 patients female. The mean age was 59.4 years. The mean concentrations of levofloxacin, ofloxacin and ciprofloxacin in aqueous humor were 577.8 ng/ml, 279.6 ng/ml and 53.0 ng/ml, respectively. The differences of concentration among the three groups were statistically significant. CONCLUSIONS: The concentration of levofloxacin 0.5% solution was highest, followed in order by ofloxacin 0.3% and ciprofloxacin 0.3%.

We evaluated the neutralizing activity in serum from three patients >1 year after recovery from Middle East respiratory syndrome (MERS) associated with mild pneumonia treated with antivirals during the MERS outbreak in South Korea at 2015. The neutralizing activity in serum was measured by pseudovirus inhibition assays. Three-fold diluted serum of subjects showed only 9.7%, 10.3%, and 2.2% reductions in relative light units. So, significant neutralizing activity was not demonstrated in any sera of three patients with mild pneumonia >1 year after being successfully treated with antiviral agents and recovering from MERS coronavirus infection.

Diffuse large B cell lymphoma (DLBCL) is one of the most common acquired immune deficiency syndrome (AIDS)-defining malignancies among human immunodeficiency virus-infected patients, and rectal cancer has recently emerged as a prevalent non-AIDS-defining malignancy. We report a case of rectal squamous cell carcinoma that was metachronous with DLBCL in an HIV-infected patient who was receiving highly active antiretroviral therapy. The patient was diagnosed with DLBCL and showed complete remission after chemotherapy. Follow-up imaging showed increased uptake at the rectum, previously treated as lymphoma. Repeated biopsy was performed and squamous cell carcinoma of the rectum was reported. After concurrent chemoradiation therapy, curative resection was performed.

Recently, the -160 C/A polymorphism, located within the regulatory region of E-cadherin promoter, has been shown to influence E-cadherin transcription by altering transcription factor binding. We examined the effect of this polymorphism on risk of gastric cancer and on histological classification of intestinal- and diffuse-type gastric cancer in 146 normal healthy individuals and 292 Korean gastric cancer patients. Genomic DNA samples were examined by polymerase chain reaction (PCR)-single strand conformational polymorphism (SSCP)-sequencing and confirmed by restriction fragment length polymorphism (RFLP). Unexpectedly, there was no significant difference in the genotype frequencies of the polymorphism between normal control and gastric cancer patients (x(2) test, p=0.433). The estimated odd ratio of C/C to A/A genotype in gastric cancer cases was 1.07 (95% confidence interval, 0.396-2.870). We also found no evidence for differences in risk for the intestinal- and diffuse-type gastric cancer. These results suggest that the -160 C/A polymorphism of the E-cadherin has no direct effect on the risk of Korean gastric cancer development and on its histological classification.

PURPOSE: Over the last 30 years, Serratia marcescens (S. marcescens) has emerged as an important pathogen, and a common cause of nosocomial infections. The aim of this study was to identify risk factors associated with mortality in patients with S. marcescens bacteremia. MATERIALS AND METHODS: We performed a retrospective cohort study of 98 patients who had one or more blood cultures positive for S. marcescens between January 2006 and December 2012 in a tertiary care hospital in Seoul, South Korea. Multiple risk factors were compared with association with 28-day all-cause mortality. RESULTS: The 28-day mortality was 22.4% (22/98 episodes). In a univariate analysis, the onset of bacteremia during the intensive care unit stay (p=0.020), serum albumin level (p=0.011), serum C-reactive protein level (p=0.041), presence of indwelling urinary catheter (p=0.023), and Sequential Oran Failure Assessment (SOFA) score at the onset of bacteremia (p<0.001) were significantly different between patients in the fatal and non-fatal groups. In a multivariate analysis, lower serum albumin level and an elevated SOFA score were independently associated with 28-day mortality [adjusted odds ratio (OR) 0.206, 95% confidential interval (CI) 0.044-0.960, p=0.040, and adjusted OR 1.474, 95% CI 1.200-1.810, p<0.001, respectively]. CONCLUSION: Lower serum albumin level and an elevated SOFA score were significantly associated with adverse outcomes in patients with S. marcescens bacteremia.

Syphilis is re-emerging worldwide due to the HIV epidemic. Prior to the introduction of penicillin, syphilis was the second most common primary cause of all cases of uveitis. Today, ocular syphilis is a rare disease, especially in an immunocompetent patient. Variable manifestation without pathognomonic signs of ocular syphilis often lead to delayed diagnosis, resulted in irreversibile loss of vision. In Korea, syphilitic uveitis has not been reported in an immunocompetent patient since 1984. We experienced a case of syphilitic uveitis in an immunocompetent man with visual deterioration. As the incidence of syphilis is increasing in these days, a high degree of clinical suspicion should be considered in patients with unexplained ocular inflammation and visual disturbances.

BACKGROUND: Antepartum, intrapartum, and postpartum preventive measures with antiretroviral drugs, appropriate delivery methods, and discouraging breastfeeding significantly decrease the risk of mother-to-child transmission of human immunodeficiency virus (HIV) infection. Herein, we investigated the pregnancy outcomes in HIV-infected Korean women. METHODS: We retrospectively reviewed medical records of childbearing-age HIV-infected women between January 2005 and June 2017 at four tertiary care hospitals in Korea. RESULTS: Among a total of 95 HIV infected women of child-bearing age with 587.61 years of follow-up duration, 15 HIV-infected women experienced 21 pregnancies and delivered 16 infants. The pregnancy rate was 3.57 per 100 patient-years. Among the 21 pregnancies, five ended with an induced abortion, and 16 with childbirth including two preterm deliveries at 24 and 35 weeks of gestation, respectively. The two preterm infants had low birth weight and one of them died 10 days after delivery due to respiratory failure. Among the 14 full-term infants, one infant was small for gestational age. There were no HIV-infected infants. CONCLUSION: The pregnancy rate of HIV-infected women in Korea is lower than that of the general population. Although several adverse pregnancy outcomes were observed, mother-to-child transmission of HIV infection was successfully prevented with effective preventive measures.
