Present report describes a 46 year old male patient with a diagnosis of major depression who developed tardive dyskinesia during bupropion therapy. Our patient had no history of neuroleptic use and his laboratory and neurologic examinations were normal. He had no family history of neurologic diseases. Although bupropion induced dyskinesia has been previously reported in the literature, it is rare and our case is the first case regarding tardive dyskinesia.

Purpose: This study investigated the effectiveness of major salivary gland ultrasonography (MSGUS) using a new grading system and shear wave elastography (SWE) in evaluating the major salivary glands of patients with Sjögren syndrome (SjS). Methods: This prospectively-designed cross-sectional study included 49 SjS patients and 49 healthy controls. Major salivary glands were examined with gray-scale ultrasonography and SWE. A new grading system for salivary glands was developed using MSGUS findings. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MSGUS and shear wave velocity (SWV) values were investigated. The MSGUS grading system and SWV values were evaluated together by logistic regression analysis. A cutoff value of SWE for salivary glands was determined. Results: The sensitivity, specificity, PPV, and NPV of MSGUS were 69.4%, 73.5%, 72.3%, and 70.6% for the submandibular gland and 69.4%, 65.3%, 66.7%, and 68.1% for the parotid gland, respectively. The mean SWV values of the parotid and submandibular glands were significantly higher in SjS patients than in controls (P<0.05). The sensitivity, specificity, PPV, and NPV for the submandibular gland (cutoff, 1.95 m/s) and the parotid gland (cutoff, 2.39 m/s) were 69.4%, 52%, 59.1%, and 63% and 82.7%, 83.7%, 83.5%, and 82.8%, respectively. Adding SWE to the parotid gland grading system increased the sensitivity and specificity (sensitivity, 82.7%; specificity, 83.7%). Conclusion Evaluating the salivary glands using MSGUS with a new grading system and SWE may contribute to the diagnosis of SjS. The combination of MSGUS and SWE may be a promising tool for diagnosing SjS.

PURPOSE: To investigate the pathophysiological role of superoxide anion and total reactive oxygen species (ROS) production by the spermatozoa of men with varicocele and its relationship with varicocele grade and semen parameters. MATERIALS AND METHODS: This prospective study included 34 men with grade II–III varicocele, regardless of their fertility status. The control group consisted of 13 healthy men. Semen characteristics were examined according to the 2010 World Health Organization criteria. The swim-up method was used for sperm preparation. Total ROS and superoxide anion production was assayed by luminol- and lucigenin-dependent chemiluminescence (CL), respectively. RESULTS: The men with varicocele had significantly higher total ROS and superoxide anion levels than the healthy control subjects (2.9±0.4 relative light unit (RLU) vs. 2.4±0.1 RLU, p=0.001 for luminol-dependent CL and 2.8±0.4 RLU vs. 2.3±0.2 RLU, p=0.002 for lucigenin-dependent CL). Cases of grade III varicocele had significantly higher superoxide anion and total ROS levels than grade II cases and control subjects (p < 0.001). Superoxide anion and total ROS levels were negatively correlated with all semen parameters. CONCLUSIONS: The superoxide anion levels produced by spermatozoa were significantly higher in varicocele patients than in control subjects. ROS production was related to increased varicocele grade, impaired semen concentration, and abnormal morphology in men with varicocele. Our findings suggest that superoxide anion overproduction may be an important step in the cascade of ROS-related damage to spermatozoa, resulting in impaired semen parameters in patients with varicocele.

To investigate the antiproliferative, anti-angiogenic, and apoptotic effects of extracts of Achillea biebersteinii (ABE) and combined treatments of ABE with 5-fluorouracil (5-FU) on HT-29 cells. Methods: The effects of ABE, 5-FU, and combined treatments on the viability of HT-29 cells were determined by 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Isobologram analysis was used to determine synergism between ABE and 5-FU. The apoptotic and anti-angiogenic effects were determined by cell death detection and human vascular endothelial growth factor ELISA method, respectively. Transcriptional and translational expressions of p53, Bax, Bcl-2, p38 MAPK, Akt, PTEN, and mTOR were also evaluated by real-time PCR and Western blotting analysis. Results: ABE decreased the viability of HT-29 cells in a dosedependent manner. Combined treatment of hexane, chloroform, and methanol extracts of Achillea biebersteinii with 5-FU at IC50 doses decreased the cell viability to 26.0%, 19.1%, and 14.9%, respectively (P0.001). Furthermore, ABE treatment alone and combination with 5-FU, induced apoptosis, significantly downregulated mTOR, Akt, Bcl-2 expression, upregulated p53, Bax, PTEN, p38 MAPK expression, and exhibited anti-angiogenetic effects. Conclusions: Our findings indicate that ABE shows synergism with 5-FU and inhibits the proliferation of HT-29 cells by inducing apoptosis and suppressing angiogenesis, which may provide biological evidence for further use of ABE in the treatment of colorectal cancer.
