Effect of Thickness and Translucency on Color Change and Masking Ability of Ceramic Materials used for Laminate Veneers. THE EUROPEAN JOURNAL OF PROSTHODONTICS AND RESTORATIVE DENTISTRY 2023; 31:383-390. [PMID: 37194571 DOI: 10.1922/ejprd_2501ayata08] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 04/14/2023] [Indexed: 05/18/2023]
Abstract
This study evaluated the effect of the thickness and translucency of lithium disilicatebased glass ceramics on resin composite substrates on color change and masking effect. Laminate veneers were fabricated using IPS e.max CAD (A1) blocks with two different light transmittance values (High translucent [HT], Low translucent [LT]). Slices of two different thicknesses (0.3 mm, 0.5 mm) were obtained (n=10) and laminate veneers were cemented on the resin composite substrates of two different shades (A2, A3.5). The color change (ΔE values) was evaluated with the CIELab color system using a spectrophotometer, while the masking effect was calculated. The data were analyzed using independent-samples t-test and two-way analysis of variance. The ceramic thickness and translucency had a significant effect on final color and masking. When HT was used, and the laminate veneer thickness decreased (0.3 mm), the masking effect in ΔE values were lower (p⟨0.05). The ΔE values (⟩3.7) were clinically unacceptable. With the increase in thickness, translucency of porcelain laminate veneers decreases showing better color masking ability. Veneer thickness seems to be more effective on the restoration's masking ability than the shade of the substrate and translucency. Cinically, in case a 0.5-mm or thinner laminate veneer is planned, tooth color, resin cement and ceramic type should be considered.

Evaluation of fibrin, cyanoacrylate, and polyurethane-based tissue adhesives in sutureless vascular anastomosis: a comparative mechanical ex vivo study. Int J Oral Maxillofac Surg 2023; 52:1137-1144. [PMID: 37019734 DOI: 10.1016/j.ijom.2023.03.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 03/18/2023] [Accepted: 03/21/2023] [Indexed: 04/05/2023]
Abstract
The stability of a microvascular anastomosis is an important prerequisite for successful tissue transfer. Advances in tissue adhesives are potentially opening new avenues for their use in sutureless microsurgical anastomosis, however they have not yet gained clinical acceptance. In this ex vivo study, a novel polyurethane-based adhesive (PA) was used in sutureless anastomoses and its stability compared with that of sutureless anastomoses performed with fibrin glue (FG) and a cyanoacrylate (CA). Stability was assessed using hydrostatic (15 per group) and mechanical tests (13 per group). A total of 84 chicken femoral arteries were used in this study. The time taken to create the PA and CA anastomoses was significantly faster when compared to the FG anastomoses (P < 0.001): 1.55 ± 0.14 min and 1.39 ± 0.06 min, respectively, compared to 2.03 ± 0.35 min. Both sustained significantly higher pressures (289.3 mmHg and 292.7 mmHg, respectively) than anastomoses using FG (137.3 mmHg) (P < 0.001). CA anastomoses (0.99 N; P < 0.001) and PA anastomoses (0.38 N; P = 0.009) could both withstand significantly higher longitudinal tensile forces compared to FG anastomoses (0.10 N). Considering the background of an in vitro study, the PA and CA anastomosis techniques were shown to be similar to each other and superior to FG, due to their stability and faster handling. These findings need to be validated and confirmed in further in vivo studies.

[PMID: 38108626 DOI: 10.1080/00016489.2023.2289584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 11/23/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND The pain that occurs after septorhinoplasty is an important factor affecting the comfort of the patient. OBJECTIVES To investigate the effect of perioperative intravenous magnesium sulfate infusion on postoperative pain and quality of recovery in patients underwent septorhinoplasty surgery. MATERIAL AND METHODS One hundred twenty patients who underwent septorhinoplasty were randomly divided into two groups. Magnesium group received intravenous magnesium after induction of anesthesia (30 mg/kg), then infused until the end of the surgical procedure (9 mg/kg). The placebo group received the same volume of saline infusion. The VAS score was used for postoperative pain assessment, and the Quality of Recovery-40 (QoR-40) score was used for the assessment of recovery status. RESULTS The postoperative 30 min, 1st, 2nd, 4th (p < .001) and 24th hour (p < .05) VAS scores of the patients in the magnesium infusion group were significantly lower compared to the placebo group. Also; in terms of physical comfort (p < .001), emotional state (p < .05), psychological support, pain and total score values (p < .001), patients in magnesium group had significantly higher QoR-40 scores than those in placebo group. CONCLUSION Intraoperative magnesium infusion, which is widely used in many surgeries to provide controlled hypotension, also contributes significantly to patient comfort with its positive effect on postoperative pain and recovery scores.

A rare cause requiring consideration in the differential diagnosis of neck masses: tularemia. J Infect Dev Ctries 2023; 17:381-387. [PMID: 37023434 DOI: 10.3855/jidc.16866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 12/10/2022] [Indexed: 04/08/2023] Open
Abstract
INTRODUCTION Tularemia is a zoonotic disease caused by the Gram-negative coccobacillus Francisella tularensis. It is frequently overlooked in the differential diagnosis of neck masses because of its rarity. The purpose of this study is to report cases diagnosed with tularemia among patients presenting to our clinic with neck masses and to share our experience. METHODOLOGY Patients presented to our hospital with cervical masses and diagnosed with tularemia were included in this retrospective study. Medical files of all patients were evaluated, and physical examination findings, titration values, date of diagnosis, location of the abscess or mass, place of residence, occupation, drinking water sources, sedimentation (SED), C-reactive protein (CRP), and white blood cell (WBC) values were recorded. RESULTS Seventy-six patients were included in the study. Forty patients (52.6%) were living in rural villages and 36 (47.4%) in urban areas. Thirty-one (40.8%) were engaged in animal husbandry and 29 (38.2%) in agriculture. In terms of drinking water sources, 59 patients (73.6%) obtained water from the mains, while 10 (13.32%) used well water. The most frequently observed clinical findings were swelling in the neck, sore throat, lethargy, and fever. Neck swelling frequently occurred in levels II and III. CONCLUSIONS Since tularemia is rare and there are no specific clinical findings, diagnosis may be problematic. Ear, nose and throat (ENT) specialists should be familiar with the clinical symptoms of tularemia in the head and neck region and should consider a preliminary diagnosis of tularemia in the differential diagnosis of persistent neck masses.

Abstract
Objective Several studies have looked at systemic immune-inflammation index (SII) (neutrophil x platelet x lymphocyte) values, which have been shown to be useful in determining tumor aggressivity and prognosis, as well as predicting recurrence risk, particularly in cancer cases. The purpose of the current study was to determine SII values in patients with parotid masses and investigate their utility in distinguishing between malignant and benign parotid tumors. Methods This retrospective study included 237 adult patients-112 women and 125 men-who were followed up on and treated for parotid mass between 2015 and 2021. The SII values determined were compared between the groups. Results The difference between the two groups was statistically significant (p = 0.001). In addition, SII values were higher in malignant tumors with perineural and lymphovascular invasion compared to other malignant tumors, although the difference was not statistically significant. Conclusions Although SII values yielded significant results in differentiating malignant from benign parotid tumors, since no significant cut-off value was determined, we do not think that they represent an effective marker capable of being used to distinguish between these tumors in clinical practice.

Abstract
OBJECTIVE: Noise-induced hearing loss is a preventable form of hearing loss that has serious social and economic impacts. This study aimed to investigate the protective effect of berberine, a potent antioxidant and anti-inflammatory agent, against Noise-induced hearing loss. METHODS: After applying distortion product otoacoustic emission, 28 female Sprague-Dawley rats were randomly divided into four groups. Group 1 was designated as acoustic trauma group, and rats in this group were exposed to white noise for 12 h at an intensity of 4 kHz 110 dB sound pressure level. Group 2 was the control group. Group 3 was designated as the berberine group, and 100 mg/kg of berberine was administered to rats in this group by intragastric lavage for five consecutive days. Group 4 was designated as the acoustic trauma+berberine group. distortion product otoacoustic emission was repeated on the 6th day of the study and cochlear tissues of rats were dissected for histopathological and immunohistochemical analyses after sacrificing rats. RESULTS: The distortion product otoacoustic emission results showed a significant decrease in signal-noise ratio values at higher frequencies in rats of the trauma group compared to those in other groups. Acoustic trauma caused severe histopathological impairment at cochlear structures together with severe 8-hydroxy-2-deoxyguanosine expression. Rats in the acoustic trauma+berberine group showed mild histopathological changes with mild 8-hydroxy-2-deoxyguanosine expression and better signal-noise ratio values. CONCLUSION: The histopathological and audiological findings of this experimental study showed that berberine provides protection in Noise-induced hearing loss and may have the potential for use in acoustic trauma-related hearing losses.

Abstract
OBJECTIVE The study aimed to analyse the hearing levels of patients with gout using extended high frequencies (EHFs) audiometry. Thus, we aimed to reveal the early detectability of potential hearing losses. DESIGN Comparative cross-sectional study. SETTINGS A single centre patient was diagnosed with gout disease. PARTICIPANTS Two groups consisted of 32 patients with gout and 32 healthy volunteers. MAIN OUTCOME MEASURES The primary outcome was hearing thresholds in pure tone (PT) audiometry and EHFs audiometry. Also, the association between audiometric results and haematological and biochemical parameters were evaluated. RESULTS There was no significant difference between groups in terms of mean hearing thresholds in PT audiometry. But, at all frequencies above 4000 Hz (4000-18 000 Hz), the hearing thresholds were significantly higher in patients with gout. Also, the hearing thresholds above 8000 Hz were positively correlated with serum uric acid levels. Hearing thresholds at higher frequencies were positively correlated with haemoglobin levels and negatively correlated with high-density lipoprotein levels. CONCLUSION To our knowledge, this is the first study in the literature demonstrating the high frequency of hearing loss in patients with gout using EHFs audiometry. We consider that using EHFs audiometry should have an important place in the early detection of potential hearing losses in gout patients.

Abstract
Objectives The purpose of this study was to investigate the fracture resistance, biocompatibility, hardness, and transverse strength of non-precious metal alloy (chromium-cobalt; Cr-Co), titanium (Ti), zirconia (Zr), polymethylmethacrylate (PMMA), and polyetheretherketone (PEEK) when employed as substructure materials according to the implant supported full arch fixed prosthesis treatment concept. Materials and Methods In total, 150 Cr-Co, Ti, Zr, PMMA, and PEEK samples (n = 30 per material) measuring 25 × 2 × 2 mm in size were produced. Of the samples, 50 (n = 10 for each material, all having dimensions of 6 × 3 mm) were subjected to biocompatibility tests. The Vickers hardness test and three-point bending test were performed; fracture resistance measurements were taken and the biocompatibility of the samples was evaluated by the XTT assay. Results Vickers hardness was highest for Zr (p < 0.05). PEEK and PMMA had the lowest (and similar) fracture resistance values (p < 0.05). Cell proliferation on the surfaces of the materials was similar between PEEK and Zr (p > 0.05), which were the most biocompatible materials. Conclusions Within the limitations of this study, the most favorable materials in terms of biocompatibility were found as PEEK and Zr. When biomechanical properties are evaluated, the most durable materials can be specified as Cr-Co and Zr. Also, further studies are needed to improve material stability.

Abstract
Aims This study aimed to explore barriers regarding insulin initiation in patients with Type 2 diabetes and investigate the relationship of some demographic characters of patients. Materials and Methods A cross-sectional study was conducted with 142 patients with Type 2 diabetes whose doctors had recommended insulin therapy and who had been unwilling to comply. The participants were patients at an endocrine outpatient clinic in Kovancilar State Hospital in the rural area in Elazig, from November 2016 to May 2017. Results Half of the patients were illiterate, 60.6% of the participants were female, and the mean age was 57.33 ± 10.56. The most commonly reported barrier was injection-related anxiety (63.4%). In total, 58.5% of the patients refused insulin therapy because they felt it indicated that their disease had worsened and that they had failed at diabetes management. Female patients were 6.9 times more likely to think injection-related anxiety that affecting their decision about insulin therapy than male patients. Elderly patients were 8.2 times more likely to think of their disease worsened than younger patient. Conclusions Patients' beliefs related to insulin therapy were very much influenced by their gender, educational status, and age. Giving patient-centered education is a cost-effective way to decrease negative health behaviors.

Abstract
Deep neck infection (DNI) refers to infections in spaces created by superficial and deep cervical fascia around the muscles and organs in the neck. Vitamin D is highly important for an effective immune system. Vitamin D receptors (VDR) have been identified in immune system cells, and particularly in T and B lymphocytes, macrophages, and dendritic cells. Vitamin D deficiency is thought to result in impaired immune response, decreased leukocyte chemotaxis, and an increased disposition to infection. The purpose of this study was to investigate whether vitamin D deficiency is an underlying occult factor in the development of DNI. Sixty-five patients aged 6 to 90, diagnosed with DNI, and 70 healthy age- and sex-compatible cases were included in the study. Serum levels of calcium, phosphorus, parathyroid hormone, and 25-hydroxy vitamin D (25(OH)D) were determined in each case. 25-hydroxy vitamin D levels above 20 ng/mL were regarded as normal, 12 to 20 ng/mL as insufficient, 5 to 12 ng/mL as deficient, and less than 5 ng/mL as severely deficient. Mean serum 25(OH)D levels were 10.4 (6.2) ng/mL in the patient group and 15.5 (6.4) ng/mL in the control group (P < .01). This difference was statistically significant (P < .01). Vitamin D was within normal limits in 9.2% (n = 6) of cases in the study group, insufficient in 29.2% (n = 19), deficient in 35.3% (n = 23), and severely deficient in 26.2% (n = 17). The equivalent values in the control group were 21.4% (n = 15), 48.5% (n = 34), 30% (n = 21), and 0% (n = 0). Serum 25(OH)D levels were significantly lower in patients with DNI compared to the healthy cases; 25(OH)D levels may be a factor in the development of DNI.

Abstract
AIM The effect of oral rehabilitation on the oral perception of implant-supported overdenture patients is a concern. This study evaluated the effects of the attachment type and palatal coverage on oral perception and patient satisfaction in maxillary implant-supported complete denture patients. SUBJECTS AND METHODS The correlation between oral perceptual ability (OPA) and patient satisfaction in three groups was investigated. Group I consisted of dentate individuals (n = 40), Group II consisted of maxillary implant-supported complete denture patients with bar attachments and palatal coverage (n = 12), and Group III of maxillary implant-supported complete denture patients with magnetic attachments and palatal coverage (n = 14). In addition, implant-supported maxillary overdentures with bar attachments, with (Group II; n = 12) and without (Group IV; n = 18) palatal coverage, were examined in terms of patient satisfaction and OPA. The relationship between OPA and patient satisfaction was assessed with the Turkish version of the Oral Health Impact Profile-14 (OHIP-TR-14) satisfaction survey. To compare oral sensory function among the groups, tactile awareness and pressure awareness were assessed. RESULTS There was no significant difference in OHIP-TR-14 scores between Groups II and III. In addition, there was no correlation between oral tactile function and patient satisfaction in Groups II and III. For patients with maxillary bar-retained implant-supported overdentures, palatal coverage did not affect the correlation between OPA and patient satisfaction, lateral pressure threshold, or tactile thickness threshold. CONCLUSION According to the results of the study, whether maxillary implant-supported overdentures were made with a bar- or magnetic-type retainer, and whether bar-retained implant-supported overdentures had an open or closed palate did not affect the correlation between patient satisfaction and oral perception.

Abstract
PURPOSE Septorhinoplasty is a surgical procedure widely employed by otolaryngologists and plastic surgeons. The purpose of this study was to investigate the effects of a single pre-emptive dose of iv ibuprofen on postoperative pain and opioid consumption in patients undergoing septorhinoplasty. MATERIAL AND METHODS 50 patients scheduled for septorhinoplasty were included in this prospective, randomized, double-blinded study. Control group (n = 25) was administered 100 mL iv saline solution 30 min preoperatively, while Ibuprofen group (n = 26) received 800 mg ibuprofen iv. in 100 mL saline solution. Intravenous fentanyl was administered with a Patient Controlled Analgesia device after surgery for postoperative pain management. Postoperative pain was evaluated using a Visual Analogue Scale (VAS) with 0 representing no pain and 10 the worst pain possible. RESULTS VAS scores at 10, 20, and 30 min and at 1, 2, 4, 8, 12 and 24 h were lower in the ibuprofen group than in the control group (p < 0.05). Total fentanyl consumption was lower in the ibuprofen group compared to the placebo group (148.8 ± 86.4 mcq vs 338.00 ± 81.00 mcq), respectively. CONCLUSION We suggest that the pre-emptive use of iv ibuprofen at a dosage of 800 mg 30 min before septorhinoplasty will be beneficial in reducing opioid consumption and pain scores.

Abstract
INTRODUCTION Thyroid cancer is the most common endocrine system cancer. Although fine-needle aspiration biopsy is the most commonly used method for diagnosis, it is not always sufficient. The aim of this study was to investigate the influence of preoperative serum thyroglobulin (Tg) concentration on differentiated thyroid cancer risk. MATERIAL AND METHODS A total of 133 patients who underwent total thyroidectomy due to various indications at the Ear-Nose-Throat Department, Ataturk University Medical School, between April 2015 and December 2015, were included in this prospective study. Histopathological diagnosis and preoperative Tg levels were compared. Receiver operating characteristic (ROC) analysis was used for detection of the cut-off to discriminate malignant from benign thyroid masses using preoperative Tg as a variable. RESULTS Malignant pathology (differentiated thyroid carcinoma) was detected in 59 out of 133 patients (44.4%) and benign pathology in 74 (55.6%). A statistically significant difference in preoperative Tg value was detected between malignant and benign cases (p < 0.05). CONCLUSION The prevalence of differentiated thyroid carcinoma was higher among patients with a preoperative serum Tg value > 188.5 ng/mL, and this may thus be used as a marker for the diagnosis of this malignancy.

Abstract
INTRODUCTION Liver transplantation (LT) remains the best treatment option for hepatocellular carcinoma (HCC). Patient selection is crucial and debated ever since the emerging of the Milan criteria in 1996. As live-donor LT is being more routinely performed worldwide, numerous new and/or expansions of the original criteria have been suggested to allow more patients to benefit from this superior treatment modality. This study aims to contribute to the ever-growing data in search for better coverage of patients with acceptable outcomes. METHODS Medical recordings of 187 adult patients who underwent LT for HCC in a 6-year period were retrospectively collected. Patients were classified by Milan and University of California, San Francisco, criteria. Survival times as well as tumor, liver disease, and recurrence-related data were recorded for each patient and the outcomes were statistically analyzed. RESULTS Factors significantly affecting recurrence and survival were histologic differentiation, number and the size of the tumor, and the presence of vascular invasion. Serum alpha-fetoprotein levels did not significantly affect outcomes. Among the patients exceeding both of the criteria, having a total tumor size of less than 160 mm was significantly associated with better outcomes (P = .007). CONCLUSION HCC patients having tumors with vascular invasion, poor differentiation, exceeding 6 in number and 160 mm in total diameter demonstrate higher recurrence rates and worse outcomes.

Abstract
BACKGROUND Venous reconstruction in living-donor liver transplantation for Budd-Chiari syndrome (BCS) has challenges because the grafts from living donors lack vena cava, and hepatic venous anastomosis must be performed on an already-thrombosed and/or stenosed inferior vena cava. Several techniques are described to overcome this problem, and we represent our experience with 22 patients. METHODS Medical recordings of 22 patients were retrospectively collected, and disease-specific data as well as recordings about surgical technique were analyzed. RESULTS Creation of a wide, triangular de novo orifice was the main method used for venous drainage, which was used in 19 patients. The remaining 3 patients had totally thrombosed vena cava; thus, direct anastomosis to the supra-hepatic portion of the vena cava was used in 2 patients and an anastomosis to the right atrium was used in 1 patient. CONCLUSIONS Venous reconstruction in BCS can be achieved without the use of patch-plasty, and the inferior vena cava can be safely resected in selected patients. Living-donor liver transplantation is a feasible option for the treatment of BCS, considering the scarcity of cavaderic donors.

Abstract
Objective Tonsillectomy is one of the most common surgical procedures performed at ear, nose, and throat clinics. Chronic recurrent tonsillitis, obstructive tonsillitis, and halitosis are among the most common indications for surgery. Determining whether the infection is chronic and the patient's annual number of infections are important in estimating the necessity for surgery to be performed due to infectious causes. Red blood cell distribution width (RDW) is a numerical value present in normal complete blood count that provides information about erythrocytes and their dimensions. Studies in recent years have shown that RDW increases in chronic infections, hypoxia, and oxidative stress. This study investigated the changes in RDW in patients with chronic tonsillitis and the effect tonsillectomy has on this value by comparing RDW between patients scheduled for tonsillectomy and normal population and examining preoperative and postoperative changes in RDW. Materials and Methods Sixty-three patients scheduled for tonsillectomy due to recurrent tonsillitis aged 4-14 years were included in the study. The control group consisted of 60 subjects comparable in terms of age and sex. Hemoglobin level and RDW were recorded by collecting 2 mlof blood before surgery and at 4 months postoperatively from all patients. Results Preoperative RDW was significantly higher in the patient group than in the control group. Comparison of patients' preoperative and postoperative RDW revealed a significant decrease in RDW after surgery. Conclusion As a biomarker showing chronic infection in patients with tonsillitis, RDW can provide support to the clinician in deciding on surgery. However, this has to be confirmed in further studies with greater participation.

Abstract
CONCLUSION Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. OBJECTIVE This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. DESIGN Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. RESULTS When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

Abstract
PURPOSE We aimed to determine the effect of a cartilage shoe graft placed between the foot of the TORP and the stapes footplate on hearing improvement and long-term displacement rates. MATERIALS AND METHODS Patients who underwent TORP ossiculoplasty were divided into two groups. The TORP-alone group consisted of 32 patients who underwent TORP placement without cartilage shoe graft and served as the control group. The study group consisted of 56 patients who underwent placement of cartilage shoe graft together with TORP. Pure-tone audiometry was administered to all patients before and 3, 6 and 12 months after surgery. Indications for surgery, surgical technique used, postoperative complications, and air and bone conduction thresholds at 500, 1000, 2000 and 4000 Hz were recorded for all patients. RESULTS No significant difference in postoperative air-bone gaps was observed between the groups. The number of patients with air-bone gaps less than 20 dB was 14 (25%) in the study group and 8 (25%) in the control group. There was no significant difference in changes in air-bone gaps between the groups. Dislocation of the prosthesis was observed in 3 patients in the study group (5.3%) and 4 in the control group (12.5%). There was less dislocation of the prosthesis in the study group, but the difference was not statistically significant. CONCLUSION Placement of a cartilage graft between the footplate of the stapes and the foot of the prosthesis may have positive effects on long-term hearing improvement and rates of prosthesis displacement. Further research with larger patient numbers is needed to identify the advantages of shoe graft.

Abstract
PURPOSE Obstructive sleep apnea syndrome (OSAS) is a disorder that is characterized by repetitive pauses in breathing during sleep. Airway obstruction episodes can lead to ischemia or hypoxia in tissues. Hypoxia may also have an effect on bone metabolism. In this study, we aim to investigate both the bone metabolic abnormalities and bone mineral density (BMD) in OSAS patients compared to individuals without OSAS. METHODS Twenty-one male patients with OSAS and 26 control subjects, also male, enrolled in this study. Serum calcium, phosphorus, alkaline phosphatase, and urinary desoxypiridinoline levels were measured in all participants, and BMD was evaluated using DEXA (Hologic QDR 2000). The BMD was measured in the lumbar spine (L1-L4), the femoral neck, and total femur region. RESULTS No statistically significant difference was noted between the two groups with respect to demographic data, except for body mass index (BMI). We adjusted the statistical analyses in line with the BMI and noted significant differences between OSAS patients and control subjects with regard to lumbar L1-L4 t score, lumbar L1-L4 BMD, and femoral neck BMD values (p ≤ 0.001). We find significant correlations with lumbar L1-L4 BMD (r = -0.4; p = 0.023) and lumbar L1-L4 t score values (r = -0.5; p = 0.012). CONCLUSION Our study indicates that there is a relationship between OSAS and osteoporosis. However, further controlled studies comprising a greater number of patients are needed to investigate the relationship between osteoporosis and OSAS.

Abstract
BACKGROUND AND PURPOSE While CT has found wide use in medical practice, it is also a substantial source of radiation exposure and is associated with an increased lifetime risk of cancer. There is an urgent need for new approaches to reduce the radiation dose in CT. In this regard, ASIR is an alternative method to FBP. We assessed the effect of ASIR on dose reduction in adult head CT. MATERIALS AND METHODS We retrospectively evaluated a sample of 149 adult head CT examinations that were divided into 2 groups, STD and LD. We lowered the tube current and used ASIR in the LD group. SNR and CNR were analyzed. Dose parameters were recorded while subjective image noise, sharpness, diagnostic acceptability, and artifacts were graded. The Student t test, the Mann-Whitney U test, and κ statistics were used for statistical analyses. RESULTS We achieved a dose reduction of 31% in the LD group (STD, 2.3 ± 0.1 mSv; LD, 1.6 ± 0.1 mSv; P < .001). There was no significant difference in the noise measured in the air between the 2 comparison groups (P = .273). Noise in the CSF was higher in the STD group (P < .001), while the noise in the WM was higher in the LD group (P < .001). Differences in the CNR between groups were insignificant, but the STD group displayed better SNR values. There was no significant difference in the modal scores of diagnostic acceptability (P = .062) and the artifacts (P = .148) between the 2 groups. Better scores for subjective image noise (P < .001) and sharpness (P = .04) were observed in the STD group. CONCLUSIONS ASIR appears to be useful in reducing the dose in adult head CT examinations. While the effect of ASIR on noise reduction observed in the present study of head CT is less than that reported previously in abdomen and chest CT, these findings encourage further prospective studies in larger patient samples.

Abstract
OBJECTIVE To investigate the results of rhomboid excision and the Limberg flap procedure to treat pilonidal sinus disease. METHOD The records of 411 patients with pilonidal sinus disease, who underwent rhomboid excision and Limberg flap procedure, were analysed. All sinus tracks were resected en bloc, and a Limberg flap was prepared from left or right gluteal region. A suction drain was routinely used. RESULTS The mean follow-up period was 109.2 +/- 4.5 months (range: 12-183 months). Recurrence occurred in 12 (2.91%) patients who were all male. In 42 (10.21%) patients, anaesthesia or hypoaesthesia of the upper portion of the flap occurred; this was temporary in 25 patients. Twelve (2.91%) patients developed a seroma and 15 (3.64%) a wound infection. The average hospital stay was 3.2 days (range: 1-10 days), and the average time of return to work was 12.4 days (range: 7-18 days). The average time to walk without pain was 13.4 days (range: 10-28 days) and the average time to sitting on the toilet without pain was 16.1 days (range: 12-28 days). CONCLUSION The Limberg flap procedure is effective and has a low complication rate, short time for returning to normal activity and short hospitalization.

Abstract
A rare case of thymic carcinoma with multiple brain metastasis is reported. In our extensive review of the literature only six of 30 reports of intracranial thymoma metastasis describe multiple metastases. A 38-year-old man presented with signs of raised intracranial pressure that had began 15 days previously. Cranial MRI revealed over 70 cystic lesions in the supra and infratentorial regions. Stereotactic biopsy was planned. On the second day of his admission he deteriorated and died the following day. The autopsy revealed a mass in the mediastinum. In the brain parenchyma were multiple cystic lesions between 0.5 and 3 cm in diameter. Histopathologically they were diagnosed as metastases from the thymic carcinoma. The mean survival with a single brain metastasis is approximately 256 days, whereas with multiple brain metastases it is only 64 days, thus treatment of this tumor demands prompt surgery whenever possible and optimal adjuvant therapy.

Abstract
We studied retrospectively the effectiveness of the repeated lumbar CSF tap test (RTT), lumbar external CSF drainage (LED) and radioisotope cisternography (RIC) in predicting the outcome of shunt surgery, as well as the diagnostic and prognostic value of periventricular hyperintensity (PVH) and of the classic clinical triad in normal pressure hydrocephalus. Two hundred and seventy patients were referred to the Departments of Neurosurgery, in Nancy, France and in Istanbul, Turkey. The decision to perform surgery was based on the clinical presentation (all patients had at least two symptoms of the classic clinical triad), neuroimaging examinations and the results of the RTT (taps were performed on three consecutive days and at each tap a minimum of 30 to 40 cc of CSF was removed), the LED (drainage was performed for 3 days and the volume of CSF drained daily was a minimum of 150 to 250 cc) or the RIC. After all shunt procedures, postoperative assessments verified improvements in 88% of the RTT group, 91% of the LED group and 66% of the RIC group. Gait disturbance had improved in 90% at the end of the second and twelfth month follow-up. Cognitive dysfunction had improved in 79% at the second and in 77% at the twelfth month follow-up. Urinary incontinence had improved in 66% at the second and in 62% at the twelfth month follow-up. From the surgical point of view, the greatest difficulty is not to make the diagnosis, but rather to identify the appropriate patients to operate on. The decision to perform shunt surgery should be based on strict clinical findings associated with CT and MRI criteria and especially with positive RTT or LED test results.

Abstract
Head trauma causes two kinds of injury in the neural tissue. One is the primary injury which occurs at the time of impact. The other one is a secondary injury and is a progressive process. Free radicals are produced during oxidative reactions formed after trauma. They have been thought to be responsible in the mechanism of the secondary injury. Some studies have been conducted to demonstrate the role of free oxygen radicals in neuronal injury. The alterations in the free radical level during the early posttraumatic period and the effect of a free radical scavenger on these alterations have not been studied as a whole. We aimed to demonstrate the free oxygen radical level changes in the early posttraumatic period and the effect of melatonin, which is a potent free radical scavenger, on the early posttraumatic free radical level. A two-staged experimental head trauma study was designed. In stage one, posttraumatic free radical level changes were determined. In the second stage, the effect of melatonin on the free radical level changes in the posttraumatic period was studied. Two main groups of rats each divided into four subgroups were studied. Rats in one of the main groups underwent severe head trauma, and malondealdehyde (MDA) levels were measured in the contused cerebral tissue at different time points. Rats in the other main group also underwent the same type of trauma, and melatonin was injected intraperitoneally at different time points after trauma. The MDA level alteration in the tissue was determined after the injection of melatonin. The MDA level increased rapidly in the early posttraumatic period. But in time, it decreased in the groups with only trauma. In the melatonin-treated group, the MDA level decreased after the injection of melatonin, when injected in the early posttraumatic period, compared to the control and trauma groups. However, melatonin increased MDA to a higher level than in the groups with only trauma and the control group when injected later than 2 h after trauma. The MDA level increases in the very early posttraumatic period of cerebral trauma and decreases in time. Melatonin, which is the most potent endogenous free radical scavenger, when injected intraperitoneally to the cerebral traumatized rats in the very early posttraumatic period, causes a significant decrease in the MDA level. But, melatonin, when injected more than 2 h after trauma, increases the MDA level in experimental cerebral trauma in rats.
