Collet-Sicard Syndrome With Hypoglossal Nerve Schwannoma: A Case Report.

Collet-Sicard syndrome is a rare syndrome that involves paralysis of 9th to 12th cranial nerves. We report an uncommon case of schwannoma of the hypoglossal nerve in a 39-year-old woman presented with slurred speech, hoarse voice, and swallowing difficulty. Physical examination revealed decreased gag reflex on the right side, decreased laryngeal elevation, tongue deviation to the right side, and weakness of right trapezius muscle. MRI revealed a mass lesion in the right parapharyngeal space below the jugular foramen. The tumor was surgically removed. It was confirmed as hypoglossal nerve schwannoma via pathologic examination. Videofluoroscopic swallowing study revealed aspiration of liquid food and severe bolus retention in the vallecula and piriform sinus. Laryngoscopy revealed right vocal cord palsy. Electrodiagnostic study revealed paralysis of the right 11th cranial nerve. In summary, we report an uncommon case of schwannoma of the hypoglossal nerve with 9th to 12th cranial nerve palsy presenting as Collet-Sicard syndrome.

Prevalence and Related Characteristics of Carpal Tunnel Syndrome Among Orchardists in the Gyeongsangnam-do Region.

OBJECTIVE: To determine the prevalence and related characteristics of carpal tunnel syndrome (CTS) in orchardists and to investigate the association between electrodiagnostic severity and physical examinations. METHODS: Between July 2013 and September 2014, 377 subjects (174 men and 203 women) visited the Gyeongsang National University Hospital's Center for Farmer's Safety and Health. All the subjects underwent electrodiagnostic tests and physical examination, including Phalen's test, Tinel's sign, and Durkan's carpal compression test (CCT). The subjects were classified into 2 groups, the normal group and the CTS group, according to electrodiagnostic test results. To determine the related characteristics of CTS, potential variables, including age, sex, drinking, smoking, body mass index, waist circumference, and total work time, were compared between the 2 groups. The association between electrodiagnostic severity and physical examinations was analyzed. RESULTS: CTS was diagnosed in 194 subjects based only on electrodiagnostic test results, corresponding to a prevalence of 51.5%. Among the variables, mean age (p=0.001) and total work time (p=0.007) were significantly correlated with CTS. With respect to the physical examinations, low specificities were observed for Tinel's sign, Phalen's test, and Durkan's CCT (38.4%, 36.1%, and 40.9%, respectively) in the subjects aged ≥65 years. In addition, Phalen's test (p=0.003) and Tinel's sign (p=0.032) in men and Durkan's CCT (p=0.047) in women showed statistically significant differences with increasing CTS severity. The odds ratio was 2.066 for Durkan's CCT in women according to the multivariate logistic regression analysis. CONCLUSION: CTS prevalence among orchardists was high, and Durkan's CCT result was significantly quantitatively correlated with the electrodiagnostic test results. Therefore, Durkan's CCT is another reliable examination method for CTS.

Ureteral Rupture Caused by a Suprapubic Catheter in a Male Patient With Spinal Cord Injury: A Case Report.

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, renal dysfunction, bladder cancer, and so forth. To the best of our knowledge, ureteral rupture is an unusual complication of catheterization, and ureteral rupture has been rarely reported in SCI patients. Therefore, here we report a case of ureteral rupture caused by a suprapubic catheter used for the treatment of neurogenic bladder with vesicoureteral reflux in a male patient with SCI. Due to SCI with neurogenic bladder, ureteral size can be reduced and the suprapubic catheter tip can easily migrate to the distal ureteral orifice. Thus, careful attention is required when a catheter is inserted into the bladder in patients with SCI.

Shikonin induces programmed necrosis-like cell death through the formation of receptor interacting protein 1 and 3 complex.

An alternative cell demise programmed necrosis has also been proposed when apoptotic machinery is impaired or blocked during tumor necrosis factor alpha (TNFα) stimulation. Shikonin (SKN), an herbal extract from the Chinese plant, has been reported to induce either apoptosis or necrosis depending on cell types or its concentrations. In this presentation, SKN caused cell death of NIH3T3 in a dose-dependent manner. Intriguingly, SKN-mediated cell death was in part protected by necrostatin-1 (Nec-1), a specific inhibitor of programmed necrosis, but not zVAD a pan-caspase inhibitor. SKN directly mediated cell death via receptor interacting protein1 and 3 (RIP1-RIP3) complex formation, which is required for TNFα-mediated programmed necrosis. Additionally, SKN-caused cell death was reversed by a reactive oxygen species (ROS) scavenger N-acetylcysteine (NAC) whereas TNFα-mediated necrosis was successfully protected by butylated hydroxyanisole (BHA), implying that ROS may be differentially derived from death inducing agents. Concurrently with the protective effect of the ROS scavenger or Nec-1 on TNFα or SKN, the RIP1-RIP3 complex was significantly affected in the presence of those agents. Here, it is highlighted that SKN as well as TNFα can directly mediate cell death via a pronecrotic complex, but ROS were generated via different routes depending on cell death-inducing agents.

Korean Brain Rehabilitation Registry for rehabilitation of persons with brain disorders: annual report in 2009.

This first annual report provides a description of patients discharged from rehabilitation facilities in Korea based on secondary data analysis of Korean Brain Rehabilitation Registry V1.0 subscribed in 2009. The analysis included 1,697 records of patients with brain disorders including stroke, traumatic brain injury, brain tumor and other disorders from 24 rehabilitation facilities across Korea. The data comprised 1,380 cases of stroke, 104 cases of brain injury, 55 cases of brain tumor, and 58 cases of other brain diseases. The functional status of each patient was measured using the Korean version of the Modified Barthel Index (KMBI). The average change in the KMBI score was 15.9 for all patients in the inpatient rehabilitation facility. The average length of stay for inpatient rehabilitation was 36.9 days. The transfer rates to other hospitals were high, being 62.4% when all patients were considered. Patients with brain disorders of Korea in 2009 and measurable functional improvement was observed in patients. However, relatively high percentages of patients were not discharged to the community after inpatient rehabilitation. Based on the results of this study, consecutive reports of the status of rehabilitation need to be conducted in order to provide useful information to many practitioners.
