RESUMO
BACKGROUND: The aim of our study was to describe musculoskeletal system tuberculosis (TB) as a single-center experience. METHODS: This is a retrospective observational study conducted at a TB Dispensary in the east Mediterranean part of Turkey between 2004 and 2020. The clinical and demographic characteristics including age, gender, involvement location and duration of illness, presenting complaint, local examination findings, treatment outcome were retrieved and analyzed from the case files. Statistical analyses were performed using SPSS Statistics version 17.0 (IBM). The normality of data analysed by using Kolmogorov-Smirnov. The descriptive statistics were reported as mean ± standard deviation, medians, and ranges (min-max). RESULTS: Overall, 31 patients (3.2 % of all TB cases) with a mean age of 44.2 ± 16.7 years had musculoskeletal tuberculosis. The mean duration of treatment was 12.9 ± 5.5 months. Of the 31 patients, six (19.4 %) had concomitant pulmonary TB. One of the patients was in the pediatrics age group, and two of them were in the geriatric group. The most affected area was the vertebra. The most common complaint of the patients was back pain and seen in 22 patients (70.9 %). CONCLUSIONS: The physicians should be suspicious about the diagnosis of musculoskeletal TB disease. If the diagnosis and treatment are delayed, spinal damage and other consequences might be incurable.

BACKGROUND AND AIM OF THE STUDY: In vitro studies have shown a reduction in radial artery spasm with the use of calcium antagonists. The purpose of this study was to evaluate the efficacy of topical treatment of the radial artery conduit using either verapamil or nicardipine before the anastomoses. METHODS: This prospective randomized study included 131 patients, who underwent coronary artery bypass grafting surgery with the use of the radial artery as a conduit. In 65 patients, the harvested radial artery was topically treated with verapamil and in 66 patients with nicardipine. After harvesting the radial artery, the direct flow through the conduit was measured in vitro before 5-minute incubation in nicardipine or verapamil and measured again after incubation. The flow before and after incubation was compared. Postincubation flow was also compared in the two groups. After performing the anastomosis, the flow through the radial artery was measured in vivo. RESULTS: The mean flow after NaCl incubation was 19.93 ± 12.66 mL/min and after incubation in the Ca+ channel blocker 47.16 ± 14.58 mL/min (P < .001). No significant difference in postincubation free flow was found between verapamil (46.29 ± 15.43 mL/min) and nicardipine (48.01 ± 13.77 mL/min; P = .503). CONCLUSION: Topical treatment with Ca+ channel blockers reduces radial artery spasm and significantly increases the free flow through the radial artery conduit. Nicardipine is a safe and effective alternative of verapamil in preventing spasm of radial artery conduit.

BACKGROUND: Nephron-sparing surgery (NSS) is currently the recommended treatment modality for selected renal tumors. The prognostic significance of positive surgical margin (PSM) and surgical margin width (SMW) after NSS is controversial. AIM: To evaluate the effect of PSM and SMW on cancer-specific survival (CSS) in patients who underwent NSS. MATERIALS AND METHODS: The pathological samples of 142 patients who underwent NSS were reviewed. Patients were divided into two groups with PSM and negative surgical margin (NSM), and after that those with PSM were divided into two groups according to SMW as those with 0.1-2 mm and those >2 mm. CSS was calculated using Kaplan-Meier method. Cox regression analysis was used to adjust the clinicopathologic variables. A P value < 0.05 was considered statistically significant. RESULTS: Local recurrence rate and distant metastasis rate were higher in patients with PSMs than those with NSMs (P = 0.018 and P = 0.039, respectively). However, there was no significant difference between the two groups in terms of CSS. In the group with SMW 0.1-2 mm, the tumor diameter was longer (P = 0.018), enucleation number was higher (P = 0.026), and local recurrence was higher (P = 0.034) than the group with SMW > 2 mm. There was no significant difference between the two groups in terms of CSS. CONCLUSION: In patients who underwent NSS, PSMs and SMWs have a negative effect on local recurrence but have no significant effect on CSS.

Leishmaniasis caused by more than 20 species of genus Leishmania is transmitted by the bite of infected phlebotomine sand flies. The studies on Leishmania infection in cats is very few in Turkey and therefore we aimed to screen stray cats living in city of Izmir located in western Turkey using nested PCR targeting kinetoplast DNA and serological techniques (ELISA and IFA). Leishmania DNA positive samples were also studied by ITS1 real time PCR. Whole blood and serum samples were obtained from stray cats (n: 1101) living in different counties of Izmir. In serological assays, a serum sample was considered positive in 1:40 dilution in IFA and for ELISA a serum sample was accepted positive when the absorbance value (AV) exceeded the mean AV + Standard Deviation (SD) of the negative control serum samples. According to the results, the seropositivity rates were 10.8% (119/1101) and 15.2% (167/1101) by in house ELISA and IFA, respectively. Among serology coherent samples, the seropositivity rate was 11.1% (116/1047) as detected by both assays after discordant samples (n: 54) were discarded. Of the 1101 stray cats, six (0.54%) were positive by nested PCR while only one of these six samples was positive by ITS1 real time PCR. During PCR, three controls designated as Leishmania infantum, Leishmania tropica, and Leishmania major were used for species identification. According to nested PCR results, L. tropica was identified in two cats (no.76 and 95). In another cat (no. 269), there were two bands in which one of them was well-matched with L. infantum and the other band had â¼850 bp size which does not match with any controls. Remaining three cats (no. 86, 514, and 622) also had the â¼850 bp atypical band size. ITS1 real time PCR detected L. tropica in only one cat (no. 622) which showed an atypical band size in nested PCR. These results indicated that three cats with only one atypical band (no. 86, 514, and 622) and the cat with mixed infection (no. 269) were infected with L. tropica. Altogether, L. tropica was detected in all six DNA positive cats and L. infantum was detected in one cat with mixed infection. In conclusion, although the reservoir role of cats in nature is still unclear the high seroprevalence rate against Leishmania parasites and detecting parasite DNA in stray cats in Izmir indicates that the stray cats are frequently bitten by infected sand flies. Further research activities are required to reveal the frequency of leishmaniasis in cats in different regions of Turkey where Leishmania species are endemic.

AIM: We evaluated the short-term effect of repeated pain exposure on the pain responses of newborn infants using different pain assessment methods, as this area had been under-researched. METHODS: We compared 20 term, large for gestational age infants and 40 term, appropriate for gestational age controls. All had undergone a heel stick for a newborn screening test just before discharge, but the larger babies had also undergone at least other five painful stimuli prior to that. A pulse oximeter and a skin conductance algesimeter (SCA) were connected to the babies during the heel prick, and video recordings were made. Crying time, the Neonatal Infant Pain Scale (NIPS), heart rate, peripheral oxygen saturation (SpO2 ) and SCA measurements were compared within and between the groups. RESULTS: After the heel prick, the crying time (p = 0.021) and NIPS (p = 0.013) scores were significantly higher in the study group and the SpO2 levels were significantly lower (p = 0.009), but the heart rate (p = 0.981) was not significantly different between the groups. SCA measurements did not differ significantly between the groups. CONCLUSION: Babies who received more painful stimuli during the first few days of life showed greater pain responses during a subsequent heel prick.

WHAT IS KNOWN AND OBJECTIVE: Genetic variations in drug-metabolizing enzyme genes change drug pharmacokinetics and response. CYP2C19 is a clinically important enzyme that metabolizes citalopram (CIT). The objective of this study was to determine CYP2C19 genetic polymorphisms and to evaluate the impact of these polymorphisms on the metabolism of citalopram in a sample of the Turkish population. We also assessed *17 polymorphism in healthy subjects in this population. METHODS: The CYP2C19 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism method (209 healthy individuals and 50 patients for CIT metabolism), and the plasma concentrations of CIT and demethylcitalopram (DCIT) were quantified by high-performance liquid chromatography. RESULTS AND DISCUSSION: The CYP2C19*1 and *17 allele frequencies for the patient group and the healthy group were 71·0%, 18·0% and 81·1%, 18·9%, respectively. There was no significant difference between the two groups (P > 0·05). The mean plasma concentrations and the mean dose-corrected (C/D) plasma levels of DCIT were significantly higher in patients with the CYP2C19*1/*1 genotype compared to patients with CYP2C19*1/*2 and CYP2C19*2/*2 genotypes (P < 0·05). Furthermore, the mean metabolic ratio (MR, CIT/DCIT) was also significantly higher in the CYP2C19*1/*2 + CYP2C19*2/*2 genotypes (P < 0·05). On the other hand, plasma CIT, DCIT concentrations and M/R value in the CYP2C19*1/*1 genotypes were no different to those of the CYP2C19*1/*17 genotypes (P > 0·05). WHAT IS NEW AND CONCLUSION: Our data suggest that CYP2C19*17 polymorphism does not have a significant effect on CIT metabolism. In contrast CYP2C19*2 polymorphism has a prominent role and is likely to contribute to interindividual variability in CIT metabolism in vivo at therapeutic doses.

The purpose of this study was to investigate whether levels of fetal hypoxia markers, S100 and ischaemia modified albumin (IMA) change in cases of intrauterine growth restriction (IUGR). This case-control study included 15 intrauterine growth restricted fetuses and 20 age-matched controls. During delivery of the fetuses, cord blood and maternal blood S100 and IMA levels were studied. The fetal weight and umbilical cord pH values of IUGR fetuses were significantly lower than the control group. The mean maternal and umbilical cord blood values of S100 and IMA were similar in the two groups. IMA levels in cord blood of the IUGR group were significantly higher than maternal levels, whereas umbilical and maternal levels of IMA did not differ among control cases. In cases without brain sparing effect in Doppler ultrasonography, umbilical cord S100 and IMA levels do not change significantly in IUGR when compared with appropriate-for-gestational-age (AGA) fetuses.

UNLABELLED: This study aims to present a different technique for the closure of trocar sites in laparoscopic surgeries. MATERIALS AND METHODS: Retrospective records of cases who received the new closure technique were collected. Multifilament synthetic absorbable suture was used in this technique, with no additional tools. RESULTS: This technique was applied in a total of ten cases, which included myomectomy, hysterectomy, sacrocolpopexy, and ectopic pregnancy. No intraoperative and postoperative complications were seen in any of the cases. CONCLUSION: This new and relatively easy-to-use technique can be used as an alternative technique for the closure of trocar sites in laparoscopy.

BACKGROUND: Tooth avulsion is the most severe type of traumatic dental injuries and it results in the complete displacement of the tooth out of its socket in alveolar bone. Reimplantation of the tooth is considered to be a best treatment modality due to its biological and psychological advantages. Its prognosis depends on the extra alveolar time, the storage medium, and the patient's general health. OBJECTIVE: The aim of this study was to evaluate the effect of Capparis spinosa (C. spinosa) in maintaining the viability of human periodontal ligament (PDL) cells using a real-time cell analysis method. MATERIALS AND METHODS: Periodontal ligament cells were obtained from healthy human third molars extracted for orthodontic purposes. The storage media tested were: Dulbecco's Modified Eagle Medium (DMEM), C. spinosa, Hank's Balanced Salt Solution (HBSS), and light milk. A real-time cell analyzer system was used to evaluate cell viability. After seeding cell suspensions into the wells of the E-plate 96, PDL cells were treated with each of tested media and monitored for every 5 min for 26 h. Statistical analysis of the data was accomplished using one-way analysis of variance complemented by the Tukey test. The level of significance was set at P < 0.05. RESULTS: Dulbecco's Modified Eagle Medium (control) and C. spinosa groups had significantly higher cell index values compared with the HBSS and light milk (P < 0.05). Although, C. spinosa showed better results than DMEM (control), but this difference was not found statistically significant. CONCLUSION: Capparis spinosa can be a suitable, alternative storage medium for avulsed teeth.

BACKGROUND: Pilonidal sinus disease (PSD) is a benign disease caused by hair follicles in sacrococcygeal -region. Despite the use of different methods in treatment, there is no consensus reached for treatment modalities. In this study, we used a whole natal cleft excision and flap (WNCEF) method to remove the natal cleft in cases of extensive sacrococcygeal PSD. METHODS: 243 patients with PSD were evaluated retrospectively. 47 patients with extensive sacrococcygeal PSD were included in the study. In these patients, the natal cleft was excised by using a whole natal cleft excision and flap -(WNCEF) method which was performed by an incision to include all the natal cleft (Kite incision) and the remaining defect was closed with a single fasciocutaneous flap by sliding along the midline intergluteal sulcus. RESULTS: The mean age of patients was 25.7 years (17-43). The average hospital stay of patients was 2.7 days (2-4), mean operative time was 59 min (35-80), mean duration of drain removal was 2.7 days (2-4), mean postoperative follow-up was 16.4 months (3-24) and mean BMI was 26.9 (22-30). Flap edema occured in one patient (2.1%), seroma in three patients (6.3%) and surgical site infection requiring re-use of antibiotics were observed in two patients (4.2%). Flap -necrosis and failure did not occur in our patients. No recurrence was observed in any patient during an average follow-up of 16 months. CONCLUSIONS: In sacrococcygeal PSD treatment, removal of the natal cleft with Kite incision by WNCEF method and shifting of the midline completely are thought to be an effective method that can reduce recurrence.

OBJECTIVES: Laser Doppler flowmetry (LDF) is a non-invasive technique used for various reasons in medicine and dentistry. There are many reports of vascular and microcirculatory changes in patients with diabetes mellitus. The aim of the study was to assess the gingival blood flow (GBF) measurements in patients with chronic periodontitis (Group 1), patients with chronic periodontitis and Type 2 diabetes mellitus (Group 2) and healthy controls (Group 3). METHODS: Forty-eight individuals were included in the study and divided into three groups. Gingival blood flow measurements were taken from 16 points in the upper vestibular aspect of six anterior teeth using LDF probe. In addition, plaque index (PI), gingival index (GI), probing depth (PD) and attachment loss (AL) were registered to determine the periodontal status. RESULTS: Results showed a significant correlation (p < 0.05) in clinical indices and GBF among the groups. Moreover, in Group 1, there was a correlation between GI and AL and between PD and AL. In Group 2, a correlation was observed between PI and AL and between GI and GBF. CONCLUSION: The results revealed an increase in GBF value in the chronic periodontitis group with Type 2 diabetes mellitus compared with the group with chronic periodontitis only. Diabetes can also affect GBF due to the nature of the disease, which affects the microcirculatory status.
RESUMO
AIM: Hydrogen sulphide (H2S), recently considered the third endogenous gaseous transmitter capable of modulating many physiological processes. The purpose of this study was to analyze the morphometric and histopathological changes associated with experimental periodontitis in rats in response to systemic administration of H2S METHODS: Forty-eight Wistar rats were divided into six experimental groups: non-ligated (NL) group; ligature only (LO) group; systemic administration of NaHS (H2S donor drug) alone (NaHS) group (14 µmol/kg body weight per day); and ligature placed and systemic administration of three different doses of NaHS groups (14, 28 and 70 µmol/kg/day) (L-NaHS-14, L-NaHS-28 and L-NaHS-70, respectively). Silk ligatures were placed at the gingival margin of lower first molars. Changes in alveolar bone levels were clinically measured and tissues were histopathologically examined. RESULTS: At the end of 15 days alveolar bone loss significantly higher in the entire ligature (LO and L-NaHS-14, -28 and -70) groups compared to the unligated groups (P<0.05) but there were no statistically significant differences in alveolar bone loss between LO and L-NaHS groups. Osteoclast number was significantly lower in L-NaHS-70 group than those of L-NaHS-14 and L-NaHS-28 groups (P<0.05). The osteoblastic activity of the L-NaHS-14 and -70 groups were significantly higher than those of the other groups (P<0.05). CONCLUSION: The findings of this study suggested that NaHS, when administered systemically with three different doses, did not prevent or increase alveolar bone loss in the rat model.

AIM: The purpose of this study was to analyze histologically the effect of ozone therapy in combination with autogenous bone graft on bone healing in rat calvaria. METHODS: Critical size defects were created in calvaria of 27 male Wistar rats. The animals were divided into three groups of nine animals each: autogenous bone graft group (n = 9); autogenous bone graft with ozone therapy group (80%, 30 s 3 d for 2 wk, n = 9); non-treatment (control) group (n = 9). Animals were killed after 8 wk. Histomorphometric assessments, using image analysis software, and histological analyses were performed. Primary outcome was total bone area. Secondary outcomes (osteoblast number, new bone formation) were also measured. RESULTS: Histomorphometrically, the total bone area in the autogenous bone graft with ozone therapy group (9.3 ± 2.2) were significantly higher than that of the autogenous bone graft group (5.1 ± 1.8) (p < 0.05). Also, the ozone therapy group significantly increased the percentage of total bone area compared to the autogenous bone graft group (p < 0.05). The osteoblast number significantly increased in the autogenous bone graft with the ozone therapy group (58 ± 12.3) compared to the autogenous bone graft group (9.3 ± 3.5) (p < 0.05). Also, it was observed that autogenous bone graft with ozone therapy group showed significant new bone formation when compared to the autogenous bone graft group (p < 0.05). CONCLUSION: Ozone therapy enhances new bone formation by autogenous bone graft in the rat calvarial defect model.

BACKGROUND AND AIM OF THE STUDY: Data relating to the impact of body mass index (BMI) on outcomes after isolated aortic valve replacement (AVR) are scarce and controversial. The study aim was to investigate the predictive value of BMI for early and late mortality after isolated AVR. METHODS: Data obtained from patients who underwent isolated AVR between January 1998 and December 2010 at the authors' institution were analyzed retrospectively. Patients were allocated to five groups according to the preoperative BMI: underweight (BMI < 20 kg/m2); normal weight (BMI 20.0-24.9 kg/m2); overweight (BMI 25.0-29.9 kg/m2); obese (BMI 30.0-34.9 kg/m2); and morbidly obese (BMI > 34.9 kg/m2). Logistic and Cox regression analyses were performed to identify the independent predictors of early and late mortality, respectively. RESULTS: After excluding 20 patients who were lost to follow up, and 30 patients with missing preoperative BMI data, a total of 1,758 patients was included in the analysis. The mean follow up was 5.6 +/- 3.5 years (range: 0-13.4 years), and the mean BMI 26.8 +/- 4.3 kg/m2 (range: 17-52 kg/m2). Multivariate logistic regression analyses showed no association between early mortality and the BMI groups. Multivariate Cox regression analyses showed 'underweight' to be an independent predictor for late mortality (hazard ratio 2.89; 95% confidence interval 1.63-5.13, p < 0.0001). CONCLUSION: 'Underweight' is an independent predictor for late mortality after AVR surgery. Morbid obesity did not prove to be predictive of a worse late survival.

OBJECTIVES: The predictive value of preoperative hemoglobin (HB) level on the outcome of patients undergoing valve surgery is not well established. This study evaluated the predictive value of preoperative HB level on survival after aortic valve replacement (AVR). DESIGN: This was a retrospective analysis of prospectively collected data. SETTING: A single-center study performed in an educational hospital. PARTICIPANTS: All consecutive patients (n = 1,808) who underwent AVR between January 1998 and December 2010. INTERVENTIONS AVR MEASUREMENTS AND MAIN RESULTS: Patients were classified into 4 groups according to the preoperative HB level: very low (HB of <12 g/dL in men and <11 g/dL in women), low (HB of 12-13 g/dL in men and 11-12 g/dL in women), normal (HB of 13-14.5 g/dL in men and 12-13.5 g/dL in women), and high normal (HB of ≥14.5 g/dL in men and ≥13.5 g/dL in women). The mean follow-up duration was 5.58±3.5 years, and the median follow-up duration was 5.38 years. The mean preoperative HB was 14±1.6 g/dL for men and 13.0±2.1 g/dL for women. Early mortality (≤30 days) was 6.1% in the very-low-HB group, 5.4% in the low-HB group, 3.2% in the normal HB group, and 2.3% in the high-normal-HB group (p = 0.37). Late mortality (>30 days) was 26.1% in the very-low-HB group, 23.7% in the low-HB group, 17.1% in the normal-HB group, and 12.6% in the high-normal-HB group (p<0.0001). The multivariate logistic regression model did not identify low HB as an independent predictor for early mortality. Cox regression multivariate analysis revealed both HB level, as a continuous variable, (p = 0.006), and very-low-HB level (p<0.0001), as independent predictors of late mortality. Cox regression analyses, corrected for confounders, demonstrated that low-HB level is an independent predictor for higher overall mortality (hazard ratio = 2.00, CI 1.41-2.85, p≤0.0001). CONCLUSIONS: In patients undergoing AVR, preoperative low-HB level is an independent risk factor for late mortality, but not for early mortality.

BACKGROUND: Duplication of the spine is very rare, and this malformation is generally considered as a severe form of type I split cord malformations. To the best of our knowledge, this is the first reported case of spine duplication associated with lipomyelomeningocele. CASE: We report an exceptional case of 14-year-old, asymptomatic and neurologically intact girl with duplication of the spine and marked separation of bony elements at thoraco-lumbar region. One of the split thecal sacs includes a tethered spinal cord whereas other thecal sac has no visible neural content, and there is a neighbor lipomyelomeningocele located in the midline. CONCLUSION: A surgical operation was planned to release the tethered cord and instrumentation and fusion for scoliosis; however, the operation was declined by the patient.

OBJECTIVE: Thermal therapy has existed for thousands of years and dates back to ancient civilizations such as the Finns, Romans, ancient Chinese, American Indians, and Egyptians. Sun therapy is a form of natural Far Infrared Rays (FIR) thermal therapy. Far infrared rays are invisible rays with the longest wavelength of natural sunlight. However, sunbathing should only be done in moderation, as sunlight contains ultraviolet rays that can burn and damage the skin. More than 30 million people in Asia, Europe, and Australia receive Far Infrared Therapy with FIR lamps. They emit 2-25-micron wavebands. We aimed to investigate whether FIR therapy that uses a similar waveband improves sinusitis symptoms. MATERIALS AND METHODS: This study was conducted on 10 New Zealand rabbits of both sexes, 7-8 months old, with an average weight of 1.8-2.4 kg. They were divided into four study groups. Sinusitis was induced in rabbits by blocking the sinus ostium, whereas some were left as control. Far infrared treatment with an infra-sin device was given with or without antibiotics. Mucosal samples were evaluated microscopically regarding epithelial eruption, epithelial vacuolization, interstitial edema, vascular congestion, leukocyte infiltration, and mucosal thickening. RESULTS: We found clinical and histopathological improvements in rabbits with sinusitis on the right side of the nose, to which we applied FIR treatment with the device Infra-Sin. CONCLUSIONS: Our findings in this animal study led us to conclude that it would be beneficial to study the effects of FIR treatment on people with allergic rhinitis and sinusitis and to identify the optimal dosing, treatment duration, and intensity. To add to our findings, looking into whether FIR therapy can be used as an alternative to antibiotic treatment for human sinusitis is essential.
