Antipsychotic Use Pattern in Schizophrenia Outpatients: Correlates of Polypharmacy.

BACKGROUND: This study investigates the antipsychotic use patterns of patients with schizophrenia and its correlations in their daily drug use patterns. METHODS: Patients with schizophrenia who have regular records at two different community counselling centres (CCS) were included in the study. Information about their medications and sociodemographic data was recorded through face-to-face interviews and supporting information about their drug use patterns was obtained from their relatives/caregivers/nurse. The Clinical Global Impression Scale (severity of illness) and the General Assessment of Functionality scales were also administered. RESULTS: Patients with schizophrenia used 2.0 ± 0.81 antipsychotics daily and 3.52 ± 2.55 pills (1-18). Seventy-one percent of the patients used two or more kinds of psychotropic drugs. The most frequently used antipsychotics were quetiapine, a second generation antipsychotic, and haloperidol, a typical antipsychotic. Clinical severity, regular visits to a CCS and use of depot antipsychotics were independent predictors for polypharmacy. CONCLUSION: The rate of polypharmacy use is high in Turkey. There are multiple risk factors related with polipharmacy. New studies should focus risk factors for preventing polypharmacy.

Spinal Tuberculosis.

Spinal tuberculosis (TB) is a significant form of TB, causing spinal deformity and paralysis. Early diagnosis and treatment are crucial for avoiding multivertebral destruction and are critical for improving outcomes in spinal TB. We believe that appropriate treatment method should be implemented at the early stage of this disease and that the Gulhane Askeri Tip Akademisi classification system can be considered a practical guide for spinal TB treatment planning in all countries.

Is there any role of latent toxoplasmosis in schizophrenia disease?

BACKGROUND: A large number of studies have hypothesized that Toxoplasma gondii is a potentially relevant etiological factor in some cases of schizophrenia. By contrast, some studies have disproved this association. The aim of this study was to investigate whether latent toxoplasmosis has any role in schizophrenia disease. Additionally, the association between T. gondii and subtypes of schizophrenia, and the impacts of toxoplasmosis on psychopathology were examined in the study. METHODS: A total of 85 patients with schizophrenia and 60 healthy volunteers were included in this prospective study. Immunoglobulin G (IgG) antibody to T. gondii was examined by enzyme-linked immune-sorbent assay method. RESULTS: Seropositivity rates were 43.5% for the patients with schizophrenia and 43.3% for the healthy controls (odds ratio: 1.008, 95% confidence interval: 0.517-1.964, p = 0.981).There was no significant difference in T. gondii IgG positivity between the schizophrenia and control groups with respect to sex and age. The difference in seroprevalence of T. gondii IgG antibodies among the schizophrenia subtypes was not statistically significant (p = 0.934). No significant difference was found in Positive and Negative Syndrome Subscales between Toxoplasma-infected and Toxoplasma-free patients. CONCLUSION: In the study area with a high prevalence of T. gondii, no association between toxoplasmosis and schizophrenia was detected. These findings showed that toxoplasmosis has no role in the risk of schizophrenia disease.

Ultrasound-guided pulsed radio frequency treatment in Morton's neuroma.

BACKGROUND: Morton's neuroma is a perineural fibrosis of an intermetatarsal plantar nerve. Burning, numbness, paresthesia, and tingling down the interspaces of involved toes may also be experienced. Taking into account all of this information, we designed a prospective open-label study to evaluate the efficacy of pulsed radio frequency on Morton's neuroma. METHODS: Twenty patients with Morton's neuroma were experiencing symptomatic neuroma pain in the foot not relieved by routine conservative treatment. All of the patients had been evaluated by a specialized orthopedist and were offered pulsed radio frequency as a last option before having surgery. Initially, pain level (numerical rating scale), successful pain control (a ≥50% pain decrease was accepted as successful pain control), comfort when walking (yes or no), and satisfaction level (satisfied or not satisfied) were evaluated. RESULTS: We found a decrease in the pain level in 18 of 20 patients, successful pain control in 12, and wearing shoes and walking without pain in 16. Overall, satisfaction was rated as excellent or good by 12 patients with Morton's neuroma in this series. CONCLUSIONS: This evidence indicates that ultrasound-guided pulsed radio frequency is a promising treatment modality in the management of Morton's neuroma pain.

Effects of hypothermia on skeletal ischemia reperfusion injury in rats.

OBJECTIVE: The aim of this study was to investigate the effect of hypothermia (H) on skeletal ischemia-reperfusion (IR) injury in rats by measuring malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), nitric oxide (NO), and interleukin-1 beta (IL-1ß) in muscle, and measureing immunohistochemical-inducible nitric oxide synthase (iNOS) staining of skeletal muscle. MATERIALS AND METHODS: Eighteen Wistar Albino rats were divided randomly into three groups (sham, IR, hypothermia) (n=6). The sham group had all procedures without the IR period. The lower right extremity of rats in the IR and hypothermia groups was subjected to 2 hours of ischemia and 22 hours of reperfusion by applying a clamp on the common iliac artery and a rubber-band at the level of the lesser trochanter under general anesthesia. Rats in the hypothermia group underwent 4 hours of hypothermia during the first four hours of reperfusion in addition to a 2-hour ischemia and 22-hour reperfusion period. All rats were sacrificed at end of the IR period using a high dose of anesthesia. The tibialis anterior muscles were preserved. Immunohistochemical iNOS staining was performed, and MDA, SOD, GSH-Px, NO, and IL-1ß were measured in the muscle. RESULTS: The level of MDA, NO, and IL-1ß in muscle was increased in the IR group compared with that in the sham group, but these parameters were decreased in the hypothermia group compared with the IR group. The activities of SOD and GSH-Px in muscle were decreased in the IR group; however, these parameters were increased in the hypothermia group. The score and intensity of iNOS staining of skeletal muscle was dens in IR group, mild in hypothermia group, and weak in sham group. CONCLUSION: The present study has shown that hypothermia reduced IR injury in the skeletal muscle by decreasing the levels of MDA, NO, and IL-1ß, and increasing the activities of SOD and GSH-Px. In addition, hypothermia attenuated the score and intensity of iNOS staining.

Comparison of two main treatment modalities for acute ankle sprain.

OBJECTIVE: Acute ankle sprains are one of the most common injuries in emergency departments. Immobilization is widely accepted as the basic treatment modality for acute ankle sprains; however, immobilization method remains controversial. In this study, we aimed to compare two treatment modalities: splint and elastic bandage for the management of acute ankle sprains. METHODS: This prospective study was conducted in the emergency department. Fifty-one consecutive patients who were admitted to the emergency department owing to the complaint of ankle sprain and who were treated with an elastic bandage or a splint were included in the study. After bone injury was ruled out, treatment choice was left to the on-shift physicians' discretion. The extent of edema was evaluated before and after the treatment by using a small, graduated container filled with warm water. Volume differences were calculated by immersing both lower extremities in a container filled to a constant level. Pain was evaluated using the visual analogue scale. RESULTS: There were 25 patients in the elastic bandage group and 26 patients in the splint group. VAS scores of these groups before and after the treatment were similar. Although edema size before and after the treatment were similar between the groups, edema size reduction was significantly more in the elastic bandage group [p=0,025]. CONCLUSIONS: This study showed that treatment of acute ankle sprains with an elastic bandage was more effective than splint in reducing edema. Therefore, an elastic bandage could be preferred over a splint for the treatment of acute ankle sprains.

Effectiveness of hyperbaric oxygen and ozone applications in tissue healing in generated soft tissue trauma model in rats: an experimental study.

BACKGROUND: Soft tissue trauma is a type of acute traumatic ischemia. We investigated in this study whether the edema, inflammation and ischemia caused by the trauma could be affected positively by hyperbaric oxygen (HBO) and ozone therapy. METHODS: Soft tissue trauma was generated in a total of 63 adult male Sprague-Dawley rats. Subsequently, rats were divided into three groups. The first group was treated with ozone, the second group with HBO, and the third group served as controls. Tissue and blood samples were taken at the end of the procedures. Tissue lipid peroxidation (LPO), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), inducible nitric oxide synthase (iNOS), heme oxygenase (HO)-1, and hypoxia-inducible factor (HIF)-1 levels were detected. Hematoxylin-eosin staining was used to determine the inflammation and edema histopathologically. RESULTS: We also detected HIF-1 activity, which decreases when the oxygen concentration increases, HO-1 activity, which has anti-inflammatory effects, and iNOS activity, which releases in any type of acute case. We determined a statistically significant reduction in iNOS and LPO levels in both the HBO and Ozone groups. A significant decrease in inflammation was detected in both the Ozone and HBO groups compared with the Control group, and a significant decrease in edema was detected in all three groups. CONCLUSION: We think that HBO and Ozone therapy have beneficial effects on biochemical and histopathological findings. Related clinical trials will be helpful in clarifying the effects.

A comparison of suprascapular nerve block and procedural sedation analgesia in shoulder dislocation reduction.

OBJECTIVES: Dislocation of the shoulder joint is one of the most common dislocations. The reduction procedure is a painful procedure. In this study, 2 different treatment groups were compared for pain control during shoulder dislocation reduction. It was aimed to evaluate the differences between the groups in reduction, success, length of hospital stay, complications, side effects, patient-physician satisfaction, and ease of application. METHODS: The study was planned to be prospective and randomized. As procedural sedation analgesia (SA), titration of ketamine 1 to 2 mg/kg was administered intravenously to group 1. Suprascapular nerve block (SNB) was applied under ultrasound guidance (USG) to group 2. Conformity to normal distribution of variables was examined with the Kolmogorov-Smirnov test. The χ2 test and Fisher test were used to evaluate differences between the groups in categorical variables and the Mann-Whitney U test, and a value of P<.05 was accepted as statistically significant. RESULTS: The study comprised a total of 41 patients; 20 in the group 1 and 21 in the group 2. No statistically significant difference was determined between the groups in terms of age (P=.916), sex (P=.972), reduction success (P=.540), and patient-physician satisfaction (P=.198). The time spent in the emergency department (ED) by patients in the SA group was signficantly longer compared with the SNB group. No side effects were observed in the SNB group. CONCLUSIONS: Suprascapular nerve block, which can be easily applied under USG in the ED, can be evaluated as a good alternative to SA in the reduction of shoulder dislocations.

Comparison of two treatment strategy for Lenke I adolescent idiopathic scoliosis.

The aim of the study study is to determine whether bilateral pedicle screw placement and posterior only spinal fusion improves sagittal correction parameters compared to alternate posterior segmental fixation in adolescent idiopathic scoliosis. 49 patients with Lenke Type 1 main thoracic curves who underwent single stage posterior only instrumentation and spinal fusion at a single center were retrospectively evaluated according to coronal radiological parameters. Patients divided into two groups of treatment strategy. Bilateral segmental fixation group's results were similar to alternate fixation group. Although quality of life or cosmetic evaluation of patients not involved in this study, alternate fixation provides similar results as bilateral segmental fixation in adolescen idiopathic scoliosis.

Serum fetuin-A levels in postmenopausal women with osteoporosis.

BACKGROUND/AIM: One of the functions of fetuin-A is the restriction of formation and expansion ofextraosseous hydroxyapatite crystals. TIhe exact correlation of fetuin-A with bone mineral density (BMD) has not been clearly elucidated yet. In this study, we aimed to assess the relationship between BMD and fetuin-A in postmenopausal women. MATERIALS AND METHODS: Fifty postmenopausal women (25 with osteoporosis, 25 healthy controls) were included in the study. All participants were comparable for age and body mass index. None of the osteoporotic patients had received any medical treatment for osteoporosis. Serum fetuin-A levels were measured by ELISA method. RESULTS: BMD scores of the groups were statistically significant (P < 0.001). Serum fetuin-A levels of the osteoporosis group were significantly lower compared to the control group (P = 0.009). Additionally, there was there was a mild to moderate positive correlation between fetuin-A and lumbar (r = 0.381, P = 0.06) and femoral (r = 0.143, P = 0.50) BMD in the osteoporotic group, though it did not reach statistical significance. CONCLUSION: Decreased fetuin-A levels in women with postmenopausal osteoporosis suggest that fetuin-A may have a role in the development of osteoporosis. Further studies are required to define the exact role of fetuin-A in bone metabolism.

Fluoroscopy for transpedicular screw placement in scoliosis: to what extent can radiation exposure be reduced by the freehand technique?

AIM: In spinal surgery, high doses of radiation are delivered during surgical procedures that require fluoroscopic control. The aim of this study was to determine the amount of radiation delivered from the fluoroscopic unit and also the factors to reduce the amount of radiation during the surgery of adolescent idiopathic scoliosis patients. MATERIAL AND METHODS: In this retrospective study 21 patients with adolescent idiopathic scoliosis treated by transpedicular screws between 2009 and 2012 were enrolled the study. Dose Area Product (DAP) values , number of views obtained during screw placement and other data were retrieved from the medical records of the patients. RESULTS: The mean number of transpedicular screws used was 18. An average of 10,1 vertebrae were instrumented. The mean number of images obtained was 7.76. Mean fluoroscopy time was 7.95 seconds. The total mean DAP was 64.6 cGy.cm < sup > 2 < /sup > . CONCLUSION: The amount of ionizing radiation transmitted to the patient and the surgical team can be reduced by freehand insertion, confirmation of screw position by AP and lateral fluoroscopic views including more than one segment, the use of K-wires as a guide in spinal segments with abnormal pedicular anatomy and neuromonitorization of the patient during the surgical correction of adolescent idiopathic scoliosis.

Comparison of ketamine-low-dose midozolam with midazolam-fentanyl for orthopedic emergencies: a double-blind randomized trial.

OBJECTIVE: Most of the fractures and dislocations are reduced in the emergency setting. Many drugs are available for procedural sedation and analgesia in the emergency department (ED); however, the adverse effects are still a common problem. The aim of our study was to compare the 2 drug combinations. METHOD: We performed a prospective, randomized, double-blinded, placebo-controlled trial of patients presenting to the ED after a traumatic event and required urgent reduction either for a fracture or dislocation. Patients were randomized to midazolam-fentanyl (MF) group or ketamine-low-dose midazolam (KM) group. Hypoxia, duration of hypoxia, need for oxygen, time to onset of sedation, recovery time, pain scores during reduction, and sedation depth were set as primary outcome measures and were recorded. RESULTS: A total of 498 patients who presented to ED with extremity injury and required closed reduction were assessed; 130 of them were approached for eligibility and 69 patients were excluded. The remaining 61 patients were randomized to either KM group (n = 31) or MF group (n = 30). Hypoxia and duration of hypoxia were significantly lower in the KM group compared with the MF group. Patients in the KM group reported significantly lower pain scores during reduction; however, adverse effects were higher compared with MF group. CONCLUSION: Both drug combinations can be effectively used for procedural sedation and analgesia; however, with lower risk for hypoxia and lower pain scores, KM combination stands as a reasonable choice for orthopedic interventions in the emergency unit.

The importance and efficacy of posterior only instrumentation and fusion for severe idiopathic scoliosis.

AIM: In mild and moderate idiopathic scoliosis (IS), posterior only instrumentation and fusion can provide satisfactory reduction. However in severe and rigid curvatures, combined anterior and posterior fusion is generally required. In this study we have aimed to evaluate the efficacy of posterior only instrumentation in severe thoracolumbar scoliosis clinically and radiologically and compare these results with the literature. MATERIAL AND METHODS: In this retrospective study, 29 consecutive patients with severe idiopathic scoliosis who underwent posterior only instrumentation and fusion between March 2003 and February 2011 were included the study. Radiological evaluation was performed with preoperative, postoperative and folllow up standing AP and lateral x-rays. Clinical evaluation was made with shoulder balance and trunk shift. REAULTS: Major curve magnitude decreased to 24,1° and compensatory curve magnitude decreased to 12.20° at postoperative period. There was no significant difference in sagittal plane angles. Major curve correction rate was %68,65 in screw only instrumentation and % 65 in hybrid instrumentation. CONCLUSION: Transpedicular screw instrumentation in severe IS is a safe and effective method in proper hands when flexibility of the curve evaluated accurately in preoperative period.

Posterior spinal fusion in adolescent idiopathic scoliosis with or without intraoperative cell salvage system: a retrospective comparison.

This study investigates efficacy and safety of routine cell salvage system use in adolescent idiopathic scoliosis patients undergoing primary posterior spinal fusion surgery with segmental spinal instrumentation. Forty-five consecutive adolescent idiopathic scoliosis patients undergoing posterior spinal fusion by two surgeons at a single hospital were studied. Intraoperative cell salvage system was used in 23 patients, and the control group was 22 patients who underwent surgery without cell salvage system. The cell salvage system was the Haemonetics Cell Saver 5. The primary outcome measures were intraoperative and perioperative allogeneic transfusion rate, difference between preoperative and discharge Hg and Hct levels. Average patient age was 14.65 ± 1.49 in cell saver group and 13.86 ± 2.0 in control group. In cell saver group, average intraoperative autotransfusion was 382.1 ± 175 ml. Average perioperative allogeneic blood transfusion need was 1.04 ± 0.7 unit in cell saver group and 2.5 ± 1.14 unit in control group. No transfusion reactions occurred in either group. Average hemoglobin level in cell saver group was 10.7 ± 0.86 and average hemoglobin level in control group was 10.7 ± 0.82 on discharge. Cell saver reduces perioperative transfusion rate in patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis.
