A calcification mass was incidentally found in the soft tissue of a patient who had a history of trauma to the extremity during examination. The patient had no symptom. The pathological analysis of the mass revealed it was an early-phase synovial sarcoma (SS). The diagnosis was made before the onset of symptoms and proper surgical intervention was performed. Therefore, in case of a <1 cm lesion clinically suspicious of myositis ossificans, SS should be taken into consideration as a possible diagnosis.

PURPOSE: Surgical equipment used in breast cancer surgery that affects wound healing and minimizes complications seems to be a popular investigation topic. The aim of this study is to evaluate the effect of plasmakinetic cautery on wound healing in patients receiving mastectomy. METHODS: Forty-six consecutive breast cancer patients receiving modified radical mastectomy were evaluated prospectively. Plasmakinetic cautery was used in 24 operations and electrocautery was used in 22 operations in random order to manage skin flaps and excise breast tissue. In the postoperative period, vacuum drainage amount and duration time as well as the start time of arm exercises were recorded. Complications like seroma, surgical site infection, hematoma, and flap necrosis were determined. RESULTS: Age, body mass index, breast volume and flap area parameters were similar in each group. Mean drainage duration was found to be 5.5 days in the plasmacautery group and 7.9 days in the electrocautery group (p=0.020). In the plasmacautery and electrocautery groups, mean drainage volume was 707 and 1,093 mL, respectively (p=0.025). There was no statistical significance between the groups when operation duration, amount of blood loss, time to start arm exercises, seroma, hematoma, surgical site infection, and flap necrosis were considered. CONCLUSION: Plasmakinetic cautery is a promising new surgical instrument that provides atraumatic, scalpel-like cutting precision and electrosurgical-like hemostasis, resulting in minimal tissue injury. So, plasmacautery shortens the drainage amount and duration time compared to electrocautery without elongating operation duration or increasing the amount of blood loss.

PURPOSE: Metabolic syndrome and obesity have been advocated to be risk factors for the development of overactive bladder (OAB). Additionally, insulin resistance is the underlying mechanism of metabolic syndrome. We aimed to investigate the association of insulin resistance with overactive bladder in female patients. METHODS: We prospectively conducted the study in our urology department. Female patients aged between 30 and 76 years old applied to our policlinics with or without OAB symptoms were enrolled. One hundred and twenty-two patients with OAB and 62 age-matched controls without OAB were included into the study. Fasting serum insulin, glucose, high-density lipoprotein (HDL-c), and triglycerides levels were measured. Insulin resistance value was obtained via the homeostasis model assessment of insulin resistance (HOMA-IR) calculator. The chi-square and Mann-Whitney U tests were used to compare differences in variables. RESULTS: Serum insulin level was found higher in female patients with OAB (11.5+/-6.2 microU/mL) relative to controls (6.4+/-2.1 microU/mL), statistically significant (P=0.036). In addition, HOMA-IR was significantly found higher in the OAB group, 2.86 (0.76 to 17.04) in comparison to controls, 1.32 (0.67 to 224), P=0.018. High-density lipoprotein cholesterol levels (HDL-c) were significantly found lower in females with OAB. CONCLUSIONS: Insulin resistance can be associated to overactive bladder and may play significant role in pathogenesis.

BACKGROUND: We compared the postoperative analgesic efficacy of caudal levobupivacaine with bupivacaine in pediatric subumbilical surgery. METHODS: Sixty American Society of Anesthesiologists I-II patients scheduled for elective minor surgery (1.5-7 years old) were randomly divided into three groups to receive caudal injections of study drugs at 0.5 ml/kg. All patients received 0.1 mg/kg oral midazolam 30 min before surgery. Group B received 0.125% bupivacaine, group L received 0.125% levobupivacaine, and group LF received 0.125% levobupivacaine + 0.5 microg/kg fentanyl. Blood pressure, heart rate and sedation (using a four-scale sedation score) were monitored perioperatively. During the postoperative period, an anesthesiologist blinded to the study groups used the Children's and Infants' Postoperative Pain Scale to monitor patients' pain and degree of sedation. The time before the first rescue analgesic was recorded as well as any side effects over the next 24 h. RESULTS: The four-scale sedation and postoperative pain scale scores in all groups were identical. Blood pressure and heart rate measured at 15 min postoperatively were lower, and time to first rescue analgesic was longer, in Group LF compared to the others. CONCLUSIONS: Caudal 0.5 ml/kg of 0.125% bupivacaine and levobupivacaine are equally effective for postoperative analgesia after subumbilical surgeries in pediatric patients. Addition of fentanyl may lower the required amount of local anesthetics.

STUDY DESIGN: A retrospective study. PURPOSE: The aim of this study was to evalute the effects of mitomycin-C, sodium hyaluronate and human amniotic fluid on preventing spinal epidural fibrosis. OVERVIEW OF LITERATURE: The role of scar tissue in pain formation is not exactly known, but it is reported that scar tissue causes adhesions between anatomic structures. Intensive fibrotic tissue compresses on anatomic structures and increases the sensitivity of the nerve root for recurrent herniation and lateral spinal stenosis via limiting movements of the root. Also, neuronal atrophy and axonal degeneration occur under scar tissue. METHODS: The study design included 4 groups of rats: group 1 was the control group, groups 2, 3, and 4 receieved antifibrotic agents, mitomycin-C (group 2), sodium hyaluronate (group 3), and human amniotic fluid (group 4). Midline incision for all animals were done on L5 for total laminectomy. Four weeks after the surgery, the rats were sacrificed and specimens were stained with hematoxylin-eosin and photos of the slides were taken for quantitive assesment of the scar tissue. RESULTS: There was no significant scar tissue in the experimental animals of groups 2, 3, and 4. It was found that there was no significant difference between drug groups, but there was a statistically significant difference between the drug groups and the control group. CONCLUSIONS: This experimental study shows that implantation of mitomycin-C, sodium hyaluronate and human amniotic fluid reduces epidural fibrosis and adhesions after spinal laminectomy in rat models. Further studies in humans are needed to determine the complications of the agents researched.

BACKGROUND: Prostate cancer (PCa) is one of the most important causes of death in men and thus new therapeutic approaches are needed. In this study, antiproliferative and anti-migration properties of a coumarin derivative esculetin were evaluated. METHODS: Human PCa cell lines PC3, DU145, and LNCaP were treated with various concentrations of esculetin for 24 to 72 hours, and cell viability was determined by the MTT test. Cell cycle and apoptosis were analyzed by using cell-based cytometer. Gene expression levels were assessed by reverse transcription and quantitative real-time PCR, cell migration was determined by the wound healing assay. The protein expression was measured by Western blotting. RESULTS: Esculetin inhibited cell proliferation in a dose- and time-dependent manner. Cell migration was inhibited by esculetin treatment. Administration of esculetin significantly reduced the cells survival, induced apoptosis and caused the G1 phase cell cycle arrest shown by image-based cytometer. The induced expression of cytochrome c, p53, p21 and p27, and down-regulated CDK2 and CDK4 may be the underlying molecular mechanisms of esculetin effect. Esculetin suppressed phosphorylation of Akt and enhanced protein expression of tumor-suppressor phosphatase and tensin homologue. CONCLUSIONS: Our findings showed that the coumarin derivative esculetin could be used in the management of PCa. However, further in vivo research is needed.

We present a case of quadriceps tendon (QT) rupture. QT ruptures can occur in all ages. The cause is mostly traumatic in origin. Spontaneous ruptures that are thought to result from predisposing conditions are rare. Post-convulsion QT ruptures lacking traumas in their history can be overlooked in clinical examinations. This should be born in mind by the attending physician, as early diagnosis and treatment of the condition can lead to satisfactory outcomes.
