Syphilis is a sexually transmitted disease caused by Treponema pallidum, which can invade various organs. Syphilis can also cause otologic symptoms such as hearing impairment, tinnitus or dizziness and these otologic symptoms can occur at any stage of syphilis and can be associated with neurosyphilis. We report here a case of rapid progressive neurosyphilis showing hearing impairment in a patient with ankylosing spondylitis. He was treated with anti-interleukin 17A monoclonal antibody. Since syphilis is one of the causes of reversible sensorineural hearing loss and syphilis infection with immunosuppression can cause progressive hearing loss if patients in immunomodulatory therapy have sensorineural hearing loss, the possibility of syphilis should be considered.

PURPOSE: We determined the usefulness of in vitro germ cell culture in nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome, no sperm in testicular sperm extraction. MATERIALS AND METHODS: This study included 44 patients (45 testicular tissues) with nonobstructive azoospermia who were diagnosed with Sertoli cell only syndrome and were found to have no sperm in testicular sperm extraction between January 2006 and July 2008. Among the 45 testicular tissues, 22 tissues were processed for culture. In the in vitro cultures, the testicular tissues were dissociated and plated on gelatin-coated dishes. Patients were divided into 2 groups according to culture success: group I, culture positive (+; n=10); and group II, culture negative (-; n=12). RESULTS: The mean patient ages were 31.73 and 31.68 years for groups I and II, respectively. The mean testicular sizes were 10.19 and 10.42 cc, respectively; the semen volumes were 2.86 and 3.04 cc, respectively; and the mean FSH, LH, and testosterone levels were 18.86 mIU/ml, 5.99 mIU/ml, and 4.46 ng/ml vs. 21.02 mIU/ml, 6.29 mIU/ml, and 4.32 ng/ml for groups I and II, respectively, with no significant differences between the groups (p>0.05). The culture rate of nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome was 45.5% (10/22). Round spermatid injection was done in 2 patients with consent of the patients, but implantation failed. Among the 45 tissues, germ cells were found in 8 tissues after pathologic reexamination. CONCLUSIONS: The in vitro culture of germ cells would be useful in the advanced treatment of nonobstructive azoospermic patients.

PURPOSE: To evaluate the pattern of meniscal tear according to the type of the tibial plateau fracture of Schatzker. MATERIALS AND METHODS: Sixty two cases of tibial condyle fracture treated between the period of 1994 and 2003 were evaluated. The fracture type was classified according to Schatzker. The pattern and extent of the meniscus tear were compared with the fracture classification. Statistical analysis was made with the Fisher's exact test. RESULTS: Meniscus tear was noted in 29 cases out of 62 fractures (46.8%). The twenty cases of minimally displaced fractures treated conservatively showed no meniscal tear. Of 18 cases of the most common type I fracture 2 (11.2%) had a meniscus tear. Of 16 type II fractures 12 (75%) had a meniscus tear. The type III fracture showed the highest prevalence of meniscus tear (76.9%, 10/13). There was statistically significant relationtionship between the type of fractures and the rate of meniscus tear (p<0.0001). CONCLUSION: The meniscus tear frequently occurred in tibial plateau fractures in Schatzker type II and III. Associated meniscus tears should be born in mind when those types of fracture are encountered.

PURPOSE: Recently, legal disputes resulting from medical accidents have been increasing annually. The purpose of this study is to determine the causes and characteristics of medical disputes brought as a result of neonatal accidents and to suggest measures to reduce the number of medical malpractice suits. METHODS: Twenty-eight medical malpractice lawsuits brought as a result of neonatal accidents between 2005 and 2009 were analyzed. RESULTS: The average time taken to resolve these lawsuits was approximately 4.4 years. The average gestational age and birth weight of the newborns in these cases were 35.3+/-4.2 weeks and 2,668+/-931 g, respectively. Twelve cases (42.9%) were concluded partially in favor of the plaintiffs, while in 10 (35.7%) cases the plaintiffs lost. In 11 of the 12 cases that were concluded partially in favor of the plaintiffs, the defendants were found guilty of violating their duty of care. Medical accidents resulted in death in 10 cases and physical disability in 18 cases, and cerebral palsy and blindness were the most common physical disabilities. The average compensation amount ordered as damages was KRW 161,389,291+/-12,636,454. CONCLUSION: In medical litigation, the standard of judgment is whether appropriate medical practices were performed based on the patient's symptoms. Thus, to comply with the medical treatment rules is paramount in securing patients' safety and protecting doctors themselves. Individual effort is necessary, but not sufficient to prevent medical accidents; multilateral, systemic reform is also required if the number of neonatal medical accidents is to be reduced.

OBJECTIVES: This study was conducted to review the diffusion process and factors affecting the adoption of the Health Center Information System (HIS). METHODS: Data were collected from POSDATA (private company), MOHW, other Ministries and local governments. To specify the date of adoption, supplementary information was collected from 40 health centers. The following three kinds of factors were analyzed. Internal factors included type, size, and innovativeness of health centers. Community factors were composed of population size, economic status, and level of education. Organizational environmental factors consisted of information score of the municipalities, financial support of the from central government, and the neighborhoodness of innovator health centers. RESULTS: All health centers in the metropolitan cities of Seoul, Gwangju and Jeju adopted the HIS. The laggards were those in the metropolitan cities of Busan (18.8%), Incheon (20.0%) and Daejun (20.0%), and cities with population more than 300, 000 (54.8%) and counties with health center hospitals (47.1%). Financially supported rural health centers adopted the HIS more rapidly than those not supported. The factors identified as being statistically significant (p< 0.05), from a univariate analysis by Kaplan-Meier method, were: (1) internal factors of the type, size and innovativeness of health centers; (2) community factors of population size and economic status; (3) organizational environmental factors of the central government financial support and the neighborhoodness of innovator health centers. A multivariate analysis, using a Cox proportional hazard method, proved the innovativeness of health centers, central government financial support and the neighborhoodness of innovator health centers, were statistically significant (p< 0.05). CONCLUSIONS: The innovativeness of health centers, financial support from central government and the neighborhoodness of innovator health centers, rather than community factors related to regional socioeconomic status, affected the adoption of the HIS in health centers. Further in-depth studies, modifying the MOHW's strategy to propagate the HIS to the laggard health centers, are recommended.

A horseshoe kidney is the most common renal fusion anomaly. It is well known that horseshoe kidneys may be associated with many urological problems, including calculi, vesicoureteral reflux, and ureteropelvic junction obstruction. However, a horseshoe kidney with unilateral severe hydronephrosis and ureteral hypoplasia is very rare. We report an 11-year-old female who underwent a retroperitoneoscopic nephrectomy for a horseshoe kidney with severe hydronephrosis and unilateral ureteral hypoplasia.

PURPOSE: This study compared the clinical outcomes of open repair, percutaneous repair, and minimal incision repair by Achillon in ruptured Achilles tendon. MATERIALS AND METHODS: The outcomes of 12 patients with open repair (group 1), 8 patients with percutaneous repair (group 2), and 10 patients with minimal incision repair by Achillon (group 3) from February 2013 to March 2016 were analyzed retrospectively. The postoperative clinical evaluations were done by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Arner-Linholm scale, mid-calf circumference difference, one-leg heel raise difference, visual analogue scale (VAS) for postoperative scarring, time to return to work, and complications. RESULTS: No significant difference in the AOFAS ankle-hindfoot score, Arner-Linholm scale, and time to return to work was observed among three groups (p=0.968, 0.509, and 0.585). The mean differences in the mid-calf circumference in groups 1, 2, and 3 were 1.09, 0.73, and 0.58, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.002). In addition, the mean VAS scores for postoperative scarring in groups 1, 2, and 3 were 7.0, 9.1, and 9.1, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.001). The mean differences in one-leg heel raising in groups 1, 2, and 3 were 2.03, 1.91, and 1.33, respectively; group 3 was significantly higher than groups 1 and 2 (p=0.010). The complications encountered were one case of deep infection in group 1 and one case of sural nerve hypoesthesia in group 2. CONCLUSION: Minimal incision repair by Achillon is recommended as an effective surgical treatment for Achilles tendon rupture because it minimizes the risk of complications, leads to an improved tendon strength and healing, and achieves cosmetic satisfaction.
