Osteoporotic quality of life, self-efficacy, and fracture protection behaviors in postmenopausal women.

It is important for postmenopausal women to acquire bone health protective behaviors to protect them from fractures. For this reason, it is necessary to evaluate bone health during menopause and to inform women. PURPOSE: This study was conducted to examine osteoporotic fracture protection behaviors, quality of life, and self-efficacy in postmenopausal women. METHODS: In the study, the data were evaluated with the socio-demographic data form, Osteoporotic Fracture Protection Scale, Osteoporosis Self-Efficacy-Efficacy Scale, European Osteoporosis Foundation Quality of Life Questionnaire-41, which includes introductory information on socio-demographic characteristics. RESULTS: It was determined that the postmenopausal women included in our study were between the ages of 45-92; more than half of them had chronic diseases; their average BMI was 29; and their DEXA score was - 3.00 ± 0.41. Among the people included in our study, those with a history of fractures had lower self-efficacy scores. It was determined that the fracture prevention scale scores of the participants were above the average, and the average of the osteoporosis-related quality of life score was high. In addition, it was determined that there was a strong positive correlation between self-efficacy and fracture prevention scale. CONCLUSION: It is important to determine behaviors to prevent osteoporotic fractures in postmenopausal women, to raise the necessary awareness and to inform patients about the precautions to be taken. It is thought that it will increase patients' quality of life by increasing their disease-related self-efficacy. Therefore, there is a need for research on providing education to op patients and examining the results.

OBJECTIVE: The aim of the present study was to determine the association between cigarette smoking, waterpipe smoking, and co-morbidity diseases on hearing loss. METHODS: A cross-sectional study was conducted among 1015 patients [386 males (38%) and 629 females (62%)] who were aged are between 25 and 65 years. The study used clinical, physical examinations and Pure-Tone Audiometry (PTA) to assess hearing. Univariate and multivariate stepwise logistic regression analyses were used for the statistical analysis. RESULTS: Out of 1015 patients assessed, 199 were cigarette smokers with hearing loss (21.6%) and 111 waterpipe smokers with hearing loss (12%). There were statistically significant differences between cigarette smokers with hearing loss regarding (p<0.001), gender (p<0.001), BMI (p<0.001), hypertension (p<0.001), tinnitus (p<0.001), vertigo and/or dizziness (p<0.001), and migraine/headaches (p<0.001). Also there were statistically significant differences between waterpipe smokers with hearing loss, none smokers concerning age groups (p<0.001), BMI (p<0.001), using MP3 players (p=0.004), family history of hypertension (p=0.026), ATP III metabolic syndrome (p=0.010), IDF metabolic syndrome (p=0.012), tinnitus (p<0.001), vertigo/dizziness (p<0.001), and migraine/headaches (p=0.025). Multivariate stepwise logistic regression analysis indicated that tinnitus (p<0.001), dizziness (p<0.001), nausea (p=0.001), headaches and migraine (p<=0.003), fatigue (p=0.004), and vertigo (p=0.022) were considered as risk predictors risk hearing loss related cigarette smokers. Also, analysis revealed that tinnitus (p<0.001), nausea (p=0.001), headaches and migraines (p<0.001), Type 2 diabetes mellitus (p<0.001), and vertigo (p=0.021), were considered as risk predictors for hearing loss related waterpipe smokers. CONCLUSION: The present study suggests cigarette smoking and waterpipe smoking, life-style factors are possible risk factors for hearing loss among smoker participants.

Effects of Interactive Telerehabilitation Practices in Office Workers with Chronic Nonspecific Neck Pain: Randomized Controlled Study.

Aim: Aim of this study is to investigate the effects of interactive telerehabilitation exercises in office workers with chronic nonspecific neck pain. Methods: Office workers (n = 120) were randomly divided into three groups between February and July 2022, taking into account the inclusion and exclusion criteria, and office ergonomics training was given to all of the participants. Group 1 participants were given an interactive telerehabilitation program (strengthening, motor control, and posture correction exercises) for 45 min per day, 3 days a week, for a total of 6 weeks. Group 2 participants were trained to do the home exercise program on their own for 45 min per day, 3 days a week, for a total of 6 weeks. Only office ergonomics training was given to Group 3 patients. Results: Statistically significant improvement in pain (p < 0.001), range of motion (ROM) (p < 0.001), neck disability status (p < 0.001), functional status (p < 0.001), and quality of life (p < 0.001) of 6-week interactive telerehabilitation application in office workers was found. Discussion: In addition to office ergonomics training, interactive telerehabilitation program is the most effective method on pain, ROM, and neck disability compared with home exercise program and office ergonomics training alone, and studies are needed on the long-term effectiveness of telerehabilitation applications and telerehabilitation treatment diversity.

Investigation of the Efficacy of Bilateral Osteoligamentous Decompression via Hemilaminectomy in Cervical Spondylotic Myelopathy: A Clinical Study.

OBJECTIVE: Cervical stability may deteriorate and kyphotic spinal deformities may develop in cervical spondylotic myelopathy (CSM) after laminectomy or laminoplasty. This study aimed to investigate the therapeutic efficacy of the "bilateral osteoligamentous decompression via unilateral hemilaminectomy approach (UHBOLD)" technique in CSM patients. METHODS: The study included 34 adult patients who underwent UHBOLD surgery for CSM between 2016 and 2022. A record was made for all patients of age, gender, number of operated levels, preoperative and postoperative long-term follow-up VAS scores, Nurick grade values and mJOA scores, kyphosis angles measured on X-ray, and spinal canal areas measured on T2-weighted MR axial images. RESULTS: Preoperative VAS scores of the patients were 6 (4-9), Nurick grade values were 3 (2-5), mJOA scores were 10.50 ± 3.42, kyphosis angles were -13.34 ± 13.69° and spinal canal areas were 87.11 ± 28.30 mm2. In postoperative long-term follow-up of these patients, VAS scores were 2 (1-5), Nurick grade values were 1 (0-5), mJOA scores were 13.94 ± 3.09, kyphosis angles were -15.07 ± 12.78° and spinal canal areas were 149.65 ± 42.57 mm2. A statistically significant difference was determined between the preoperative and the postoperative long-term follow-up VAS scores, Nurick grade values, mJOA scores, and spinal canal areas (P < 0.001). Kyphosis angles were not different (P = 0.198), and no instability was observed in any patient in long-term follow-up. CONCLUSIONS: The UHBOLD technique performed in multilevel CSM patients did not cause any change in cervical lordosis angle in long-term follow-up, did not cause cervical kyphotic deformity or cervical instability, and significantly improved Nurick grade values, and VAS and mJOA scores.

Analysis of radiological measurement parameters that can predict the type of treatment to be applied in odontoid fractures: Clinical research.

Introduction: Although various conservative and surgical treatment methods have been proposed, treatment options for patients with odontoid fractures remain controversial. This study was conducted to determine some demographic and radiological measurement parameters that can predict treatment options in patients with odontoid fractures. Materials and Methods: The patients were separated into the surgery (-) group (n = 9) and the surgery (+) group (n = 10). Patient data were recorded of age, gender, type of odontoid fracture, morphological measurement results obtained from computed tomography images, treatment regimens, duration of stay in the hospital, and mortality rate. In the operating room, a halo-vest corset or Philadelphia-type cervical collar was applied to the surgery (-) patients after the reduction of the fracture under fluoroscopy. Anterior odontoid lag screw fixation was performed on surgery (+) patients. Results: The amount of displacement of the fractured odontoid, the distance between the C1 vertebra and the odontoid process, the angle between the posterior wall of the odontoid process and the posterior wall of the clivus, the slip angle, and the anterior to posterior width of the spinal canal were not different between the groups. No difference was determined between the groups in respect of the amount of lateral displacement of the odontoid process in the spinal canal in the axial plane and the angle of the fractured odontoid process with the C2 vertebral body. Conclusion: This preliminary study showed that the demographic data and radiological measurement parameters analyzed in the present study could not be used as predictive markers either in decision-making for treatment modality or mortality risk.

Handheld wide-field fluorescence lifetime imaging system based on a distally mounted SPAD array.

In this work a handheld Fluorescent Lifetime IMaging (FLIM) system based on a distally mounted < 2 mm2 128 × 120 single photon avalanche diode (SPAD) array operating over a > 1 m long wired interface is demonstrated. The head of the system is ∼4.5 cm x 4.5 cm x 4.5 cm making it suitable for hand-held ex vivo applications. This is, to the best of the authors' knowledge, the first example of a SPAD array mounted on the distal end of a handheld FLIM system in this manner. All existing systems to date use a fibre to collect and relay fluorescent light to detectors at the proximal end of the system. This has clear potential biological and biomedical applications. To demonstrate this, the system is used to provide contrast between regions of differing tissue composition in ovine kidney samples, and between healthy and stressed or damaged plant leaves. Additionally, FLIM videos are provided showing that frame rates of > 1 Hz are achievable. It is thus an important step in realising an in vivo miniaturized chip-on-tip FLIM endoscopy system.

Development of a high-speed line-scanning fluorescence lifetime imaging microscope for biological imaging.

We report the development of a novel line-scanning microscope capable of acquiring high-speed time-correlated single-photon counting (TCSPC)-based fluorescence lifetime imaging microscopy (FLIM) imaging. The system consists of a laser-line focus, which is optically conjugated to a 1024 × 8 single-photon avalanche diode (SPAD)-based line-imaging complementary metal-oxide semiconductor (CMOS), with 23.78 µm pixel pitch at 49.31% fill factor. Incorporation of on-chip histogramming on the line-sensor enables acquisition rates 33 times faster than our previously reported bespoke high-speed FLIM platforms. We demonstrate the imaging capability of the high-speed FLIM platform in a number of biological applications.

Management of uncomplicated acute appendicitis during the COVID-19 pandemic: Appendectomy or non-surgical treatment?

BACKGROUND: This study aims to compare medical treatment and appendectomy in patients diagnosed with uncomplicated acute appendicitis during the COVID-19 pandemic. METHODS: Retrospectively analyzed were the data of 80 patients who received medical or surgical treatment for uncomplicated acute appendicitis between March 15, 2020, and August 31, 2020. The demographic characteristics of the patients, length of hospital stay, physical examination and radiology findings, laboratory results, and any complications were recorded. Patients were divided into two groups depending on the mode of treatment, as surgical and non-surgical. RESULTS: Forty patients were given medical treatment and 40 patients were directly operated on for appendicitis. Of the 40 patients who received medical treatment, 8 (20%) ended up requiring an operation due to recurrence. The mean duration of hospitalization was 2 days (range: 1-3), and the mean follow-up duration was 285.35±65.66 days (range: 101-379). The white blood cell count was significantly higher in the surgical group (p=0.004), and the length of hospital stay was longer in the non-surgical group (p<0.001). The prevalence of post-operative complications was similar for patients who underwent appendectomy directly on admission or after recurrence (p=1.000). Among the patients who received medical treatment, the most important predictors of requiring surgery were the red cell distribution width and increased appendix diameter in computed tomography (p<0.05). CONCLUSION: Medical treatment is an effective alternative in patients with uncomplicated appendicitis. Even in the case of a recurrence in follow-up, surgery due to a potential recurrence is not associated with an increased rate of complication compared to direct surgery.

Full spectrum fluorescence lifetime imaging with 0.5 nm spectral and 50 ps temporal resolution.

The use of optical techniques to interrogate wide ranging samples from semiconductors to biological tissue for rapid analysis and diagnostics has gained wide adoption over the past decades. The desire to collect ever more spatially, spectrally and temporally detailed optical signatures for sample characterization has specifically driven a sharp rise in new optical microscopy technologies. Here we present a high-speed optical scanning microscope capable of capturing time resolved images across 512 spectral and 32 time channels in a single acquisition with the potential for ~0.2 frames per second (256 × 256 image pixels). Each pixel in the resulting images contains a detailed data cube for the study of diverse time resolved light driven phenomena. This is enabled by integration of system control electronics and on-chip processing which overcomes the challenges presented by high data volume and low imaging speed, often bottlenecks in previous systems.

Time-correlated single photon Raman spectroscopy at megahertz repetition rates.

Significant improvements in time-correlated single photon counting (TCSPC) Raman spectroscopy acquisition times can be achieved through exploitation of megahertz (MHz) laser repetition rates. We have developed a TCSPC Raman spectroscopy system based on a high peak power (>40W) pulsed laser, a high pulse repetition rate (40 MHz), a custom f/1.5 spectrometer, and a 512 spectral channel × 16 time bin single photon avalanche diode line sensor. We report millisecond Raman spectrum acquisition times, a peak Raman count rate of 104 kcps, and a linewidth aggregated count rate of 440 kcps with a diamond sample. This represents a three-order-of-magnitude increase in measured Raman count rate in comparison with a 104 kHz pulsed laser operating at 300 W and a four-order-of-magnitude increase over a 0.1 W pulsed laser operating at 40 MHz. A Raman-to-fluorescence ratio of 4.76 is achieved with a sesame oil sample at a 20 MHz repetition rate. Achieving high count rates and Raman-to-fluorescence ratios unlocks the potential of combined Raman/fluorescence lifetime spectroscopy for imaging and other short acquisition time applications.

Comparison of Handmade Endoloop Versus Polymeric Endoclip for Stump Closure in Laparoscopic Appendectomy.

Background Stump closure is an important stage of laparoscopic appendectomy. This study aimed to establish whether the handmade endoloop or polymeric endoclip method was more effective for stump closure in laparoscopic appendectomy. Methods The study included 76 patients who underwent laparoscopic appendectomy between October 2017 and January 2019. Patients' demographic characteristics, duration of surgery, length of hospital stay, and any complications were retrospectively recorded from files. Patients were divided into two groups according to stump closure method as polymeric endoclip and handmade endoloop. Results Among the patients, 59.2% (n = 45) were male and 40.8% (n = 31) were female. For stump closure, the polymeric endoclip method was used in 37 patients (48.7%) and the handmade endoloop method in 39 patients (51.3%). The two groups were not significantly different in terms of age and appendix diameter ( p=0.408, p=0.218). A total of four patients (5.3%) developed wound infection, including three from the handmade endoloop group and one from the polymeric endoclip group. One patient (1.3%) in the polymeric endoclip group developed ileus. The two groups were also not significantly different in terms of complications (p = 1.000). Conclusion We conclude that both stump closure methods are safe, and the more easily accessible handmade endoloop method can be performed reliably in all hospitals, including secondary healthcare facilities such as small hospitals.

A rarely encountered case: A neuroendocrine tumor in strangulated Littre's hernia.

Littre's hernia is a rare condition that involves Meckel's diverticulum in the hernia sac. Meckel's diverticulum is the true diverticulum of the small intestine. Neuroendocrine tumors may develop in it; however, there are very few reported cases. In this study, we present a case of neuroendocrine tumor in strangulated Littre's hernia, on which we did not find a study when we reviewed the relevant literature. A 71-year-old male patient presented to our outpatient clinic with complaints of left groin pain and swelling in the groin. Acute abdomen findings were also present in the abdominal examination of the patient. The patient was operated on immediately and it was observed during the operation that the herniated Meckel's diverticulum was perforated. Segmental small intestine resection was performed. The pathology results of the patient revealed a well-differentiated neuroendocrine tumor with mucosal and submucosal localization in Meckel's diverticulum. We believe that if Meckel's diverticulum is found in the hernia sac in incarcerated hernias, it must be completely resected as a neuroendocrine tumor may develop, even if only rarely.

Quantitative real-time imaging of intracellular FRET biosensor dynamics using rapid multi-beam confocal FLIM.

Fluorescence lifetime imaging (FLIM) is a quantitative, intensity-independent microscopical method for measurement of diverse biochemical and physical properties in cell biology. It is a highly effective method for measurements of Förster resonance energy transfer (FRET), and for quantification of protein-protein interactions in cells. Time-domain FLIM-FRET measurements of these dynamic interactions are particularly challenging, since the technique requires excellent photon statistics to derive experimental parameters from the complex decay kinetics often observed from fluorophores in living cells. Here we present a new time-domain multi-confocal FLIM instrument with an array of 64 visible beamlets to achieve parallelised excitation and detection with average excitation powers of ~ 1-2 µW per beamlet. We exemplify this instrument with up to 0.5 frames per second time-lapse FLIM measurements of cAMP levels using an Epac-based fluorescent biosensor in live HeLa cells with nanometer spatial and picosecond temporal resolution. We demonstrate the use of time-dependent phasor plots to determine parameterisation for multi-exponential decay fitting to monitor the fractional contribution of the activated conformation of the biosensor. Our parallelised confocal approach avoids having to compromise on speed, noise, accuracy in lifetime measurements and provides powerful means to quantify biochemical dynamics in living cells.

Some specific microbiological parameters and prevalence of salmonella spp. in retail chicken meat from erzurum province, turkey and characterization of antibiotic resistance of isolates / Alguns parâmetros microbiológicos específicos e prevalência de SalmonellA spp. cortes de carne de frango da província de Erzurum, Turquia e caracterização da resistência aos antibióticos de isolados

Specific microbiological parameters and the presence of Salmonella spp. were investigated in 72 chicken meat samples (36 wings and 36 drumsticks) collected from markets and butcher shops. The specific microbiological parameters were determined using a conventional cultural method and the presence of Salmonella spp. in chicken samples was determined using conventional and immunomagnetic separation (IMS)-polymerase chain reaction (PCR) methods. In addition, antimicrobial susceptibility of the isolates was revealed using the Kirby-Bauer disc diffusion method. The results indicated that 30 of the 72 samples were positive for Salmonella spp. by the conventional method, and 42 of the 72 were positive by the IMS-PCR method. However, 30 of the 72 samples were positive for Salmonella spp. by both methods. The Salmonella spp. isolates were confirmed by the VITEK2 Compact System and PCR. The susceptibilities of the isolates against 10 antibiotics were determined. The results indicated that isolates (27/30) showed the highest susceptibility to gentamycin (90.00%), while the highest resistance was to nalidixic acid and tetracycline at the 100 and 93.34% levels, respectively. These results indicate a high prevalence of Salmonella spp. in poultry meat from Erzurum city, Turkey, and the antimicrobial resistance profile of these isolates should be considered for public health. The results also show that the IMS-PCR technique was superior to the conventional method for detecting Salmonella in poultry meat.KEYWORDS:Chicken meat. Salmonella. IMS. PCR. Antimicrobial. INTRODUCTION Chicken is one of the most popular food products worldwide, because of nutritional, sensorial and economic factors. Chicken is widely consumed in homes and fast-food establishments, but can become contaminated during processing. The contamination of poultry products with Salmonella and other microorganismsis due to unhygienic conditions during the production, processing, distribution, marketing and preparationstages (DOOKERAN et al., 2012). The genus Salmonella includes short rod-shaped, facultative anaerobe, Gram-negative bacteria. Warm-blooded animals and humans are natural hosts for Salmonella spp. Detecting Salmonella spp. during production and before consumption is important to prevent food-borne salmonellosis. A Salmonella infection in humans is usually caused by consuming undercooked meat or other cross-contaminated foods, such as vegetables,milk and eggs (HASSANEIN et al., 2011). According to a report published by the Centres for Disease Control and Prevention (CDC), it is estimated that about 1.2 million people in the US have been exposed to Salmonella infections, and that an average of 23.000 hospitalisations and 450 deaths occur from these infections. The prevalence rates of Salmonella spp. in chicken meat sold in Turkey are 34-68.75%. Not only in Turkey, but in most developing countries, the absence of an epidemiological surveillance system for salmonellosis cases makes it difficult to effectively assess prevalence (KÄFERSTEIN, 2003). However, Received: 09/05/18 Accepted: 05/12/18

Parâmetros microbiológicos específicos e a presença de Salmonella spp. foram investigados em 72 amostras de carne de frango (36 asas e 36 baquetas) coletadas em mercados e açougues. Os parâmetros microbiológicos específicos foram determinados utilizando um método cultural convencional e a presença de Salmonella spp. em amostras de frango foi determinada utilizando métodos de reação em cadeia da polimerase (PCR) por separação convencional e imunomagnética (IMS). Além disso, a suscetibilidade antimicrobiana dos isolados foi revelada pelo método de difusão do disco de Kirby-Bauer. Os resultadosindicaram que 30 das 72 amostras foram positivas para Salmonella spp. pelo método convencional, e 42 das 72 foram positivas pelo método IMS-PCR. No entanto, 30 das 72 amostras foram positivas para Salmonella spp. por ambos os métodos. Os isolados de Salmonella spp. foram confirmados pelo sistema VITEK2 Compact e PCR. As susceptibilidades dos isolados a 10 antibióticos foram determinadas. Os resultados indicaram que os isolados (27/30) apresentaram maior suscetibilidade à gentamicina (90,00%), enquanto a maior resistência foi ao ácido nalidíxico e à tetraciclina nos níveis de 100 e 93,34%, respectivamente. Estes resultados indicam uma alta prevalência de Salmonella spp. em carne de frango da cidade de Erzurum, Turquia, e o perfil de resistência antimicrobiana desses isolados deve ser considerado para a saúde pública. Os resultados também demonstram que a técnica de IMS-PCR foi superior ao método convencional para detecção de Salmonella em carne de frango.

Multifocal multiphoton volumetric imaging approach for high-speed time-resolved Förster resonance energy transfer imaging in vivo.

In this Letter, we will discuss the development of a multifocal multiphoton fluorescent lifetime imaging system where four individual fluorescent intensity and lifetime planes are acquired simultaneously, allowing us to obtain volumetric data without the need for sequential scanning at different axial depths. Using a phase-only spatial light modulator (SLM) with an appropriate algorithm to generate a holographic pattern, we project a beamlet array within a sample volume of a size, which can be preprogrammed by the user. We demonstrate the capabilities of the system to image live-cell interactions. While only four planes are shown, this technique can be rescaled to a large number of focal planes, enabling full 3D acquisition and reconstruction.

Efficacy of Hyperbaric Oxygen Therapy in Diabetic Foot Ulcers Based on Wagner Classification.

Diabetic foot ulcer is a common chronic complication of diabetes mellitus. In addition to conventional primary therapy, there are adjuvant therapy methods such as hyperbaric oxygen therapy for the healing of diabetic foot ulcer wounds. The present study aimed to determine the efficacy of hyperbaric oxygen therapy in diabetic foot ulcers based on Wagner classification. It was performed retrospectively from prospectively collected data. One hundred thirty patients with diabetic foot ulcers were assessed in 2 groups: 1 group received hyperbaric oxygen therapy; the other group did not. Patients were examined according to age, sex, ulcer grade based on Wagner classification; ulcer healing status; whether hyperbaric oxygen therapy was received; duration of diabetes in years; HbA1C, sedimentation, C-reactive protein levels; and presence of accompanying diseases, including peripheral arterial disease, chronic obstructive pulmonary disease, hypertension, chronic kidney disease, neuropathy, and retinopathy. The mean follow-up period was 19.5 ±â€¯4.45 months (range 12 to 28 months). Seventy-one (54.6%) patients received hyperbaric oxygen therapy, and 59 (45.4%) patients did not. All patients in Wagner grade 2 healed in both groups. In the group that received hyperbaric oxygen therapy for grade 3 and 4 patients, 35 (87.5%) and 11 (84.6%) healed, respectively. In total, 60 (84.5%) patients in the group that received hyperbaric oxygen therapy healed. The subgroup comparison conducted according to Wagner classification revealed no differences between the 2 groups of grades 2 and 5 patients. It also revealed that treatment had higher levels of efficacy in the healing of ulcers in grade 3 and 4 patients.

Cerebral ischaemia/reperfusion injury could be managed by using tramadol.

OBJECTIVES: No valid treatment modality that will repair stroke damage and provide neurological recovery has yet been identified in literature. Studies demonstrated that adequate quality of life could be provided if post-stroke pain could be treated sufficiently and timely. Besides its pain relief effects, tramadol has oedema-reducing and anti-inflammatory properties. With these in mind, this study investigated the influence of tramadol in acute and/or chronic ischaemia/reperfusion (I/R) injury. METHODS: Putting aside the Control group, 23 Wistar albino rats were distributed to four groups to investigate the acute (Sham-A, TR-A) and chronic (Sham-C, TR-C) periods of I/R injury, and temporary aneurysm clips were applied to their internal carotid arteries for 30 min. Four hours after clippage, tramadol was administered to animals of TR-A and TR-C groups intraperitoneally. After sacrificing all animals, pyknotic and necrotic neuronal cells in hippocampal cornu ammonis (CA)1, CA2, CA3 and parietal cortical regions were counted, and perivascular oedema, intercellular organization disorder (IOD) and inflammatory cell infiltration were scaled histopathologically. Additionally, tissue interleukin (IL)-1ß, IL-10, malondialdehyde, nitric oxide, tumour necrosis factor-α, caspase-3, beclin-1, Atg12, LC3II/LC3I levels were measured biochemically. RESULTS: Tramadol could minimize perivascular oedema, IOD, parietal and hippocampal neuronal necrosis, inflammatory cell infiltration in both periods of I/R injury histopathologically. Apart from inhibiting apoptosis and enhancing autophagy, tramadol had no influence on any other biochemical result. DISCUSSION: Tramadol can ameliorate the histopathological structure of ischaemic tissue in both periods of I/R injury in rat. We suggest further research investigating various dosages with different administration methods of tramadol in stroke should be conducted by adopting different explorative techniques.

Profilactic role of simvastatin and mitomycin C in tracheal stenosis after tracheal damage: Study in rats.

OBJECTIVES: We aimed to investigate the prophylactic effect simvastatin of and mitomycin C (MMC) on laryngeal and tracheal stenosis in tracheotomised rats by histopathological evaluation of laryngotracheal segment. Randomized prospective single-blind. MATERIAL AND METHOD: Standard vertical tracheotomy was performed on 24 rats. Then the animals were randomly divided into three groups as A, B and C. In group A 0.4 mg/day once daily mitomycin C was injected to the paratracheal region for 14 days. In group B daily 30 mg/kg/day simvastatin was given via gavage to rats for 14 days. In group C 2 cc/day intraperitoneal saline given to rats and the created control group by 14 days follow up. After 10 days, tracheal cannulas were removed. Three weeks later, all animals were euthanized and trachea specimens were harvested. The present study investigates the effects of MMC and Simvastatin on fibrosis, inflammation, stenosis index and tracheal wall thickness in a tracheal injury model. RESULTS: The difference between the groups in terms of degree of inflammation scores was statistically insignificant (P = 0,187). Differences between the groups were found to be insignificant in terms of the preventionof fibrosis (P = 0,993). There was no significant difference between groups in terms of stenosis index (P = 0.645). In terms of wall thickness, control, simvastatin and mitomycin C groups were statistically different (p = 0.038). The difference between post-hoc test results was between Mitomycin C and control groups (p = 0.036). Maximum wall thickness in the MMC group (0,299 mm) was significantly lower compared to the control group (0,382 mm)(P < 0,0001). Maximum wall thickness was statistically lower in the simvastatin (0.324 mm) group compared with the control group (0.382 mm) (P < 0.0001). There was no statistically significant difference between the simvastatin group (0,198 mm) and control group (0,200 mm) with respect to minimum wall thickness (P = 0.982). Minimum wall thickness was significantly lower in the mitomycin-C group (0,160 mm) comparison to the control group (0,200 mm) (P < 0.0001). CONCLUSION: It was detected that the simvastatin and MMC is not effective in preventing the tracheal stenosis, inflammation and fibrosis formation.

Clinical course of incidental parathyroidectomy: Single center experience.

OBJECTIVE: Thyroidectomy is a very common surgical procedure. Regardless of surgeon experience, incidental parathyroidectomy is a complication of thyroidectomy. The aim of this study was to identify the clinical course of incidental parathyroidectomies after thyroidectomy. METHODS: Patients who underwent thyroidectomy between January 2010 and June 2014 were evaluated retrospectively. Pathology reports were reviewed for the presence of parathyroid tissue in the thyroidectomy pathology specimens. Information regarding demographic, laboratory variables, operative details, and postoperative complications were collected. RESULTS: Incidental parathyroidectomy was found in 178 out of 3022 patients who had thyroidectomy (5.8%). Types of surgeries performed for 178 patients were total thyroidectomy (TT) in 132(74.2%) cases, TT and central lymph node dissection(CLND) in 30 (16.9%) cases, lobectomy in seven cases (3.9%), completion thyroidectomy in five (2.8%) patients and modified cervical lymph node dissection in four (2.2%)patients. One and two parathyroid glands were accidentally removed in 152 (85.3%) and 26 (14.7%) patients, respectively. In the entire series, biochemical temporary postoperative hypocalcemia occurred in 75(42.1%) patients and permanent hypocalcemia occured in 12 (6.7%) patients with incidental parathyroidectomy. There was not a statistically significant difference regarding the occurrence of postoperative permanent hypocalcemia between the patients who had incidental parathyroidectomy of one gland and the patients with two incidental parathyroidectomies (p=0.114). CONCLUSION: Incidental parathyroidectomy is not uncommon during thyroidectomy. No association between inadvertent parathyroidectomy and postoperative permanent hypocalcemia was found.

Effects of Sulphasalazine in Cerebral Ischemia Reperfusion Injury in Rat.

BACKGROUND: Management of cerebral ischemia/reperfusion (I/R) injury is still difficult process today. AIMS OF THE STUDY: Aim of present study was to investigate therapeutic properties of sulfasalazine in cerebral transient I/R injury in rat. METHODS: Except Control group (n = 5), 20 Wistar albino rats were allocated for acute and chronic stage investigation of I/R injury, and temporary aneurysm clips were attempted to both internal carotid arteries for thirty min. Four hours later, 40 mg/kg once a day sulfasalazine was administered to animals of SL-A and SL-C groups, orally. Animals were decapitated, following which pyknotic and necrotic neuronal cells, perivascular edema, irregularities of intercellular organization (IIO) of hippocampal regions, and cortical necrotic neurons of parietal lobe were counted or scaled histopathologically. Tissue malonyldialdehyde (MDA), myeloperoxidation (MPO), total nitrite/nitrate (NO), interleukin 1-beta (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) level values were evaluated biochemically. RESULTS: Sulfasalazine could reduce perivascular edema, IIO, cortical and hippocampal neuronal cell death in both stages. It could decrease MDA in acute stage, but not reduce IL-1ß, IL-6, MPO, NO, and TNFα levels. It could increase IL-1ß levels in chronic stage but not affect to IL-6, MPO, MDA, NO, TNF-α levels. CONCLUSION: Sulfasalazine could improve histopathological architecture of hypoxic tissue in both stages of I/R injury in rat. It could inhibit lipid peroxidation cascades just in acute stage. These results suggested that therapeutic mechanisms of sulfasalazine in cerebral I/R injury should be investigated by using more specific laboratory methods in future studies.
