Abstract
BACKGROUND Venom immunotherapy (VIT) is an effective treatment in the patients at high risk of anaphylaxis or life-threatening systemic reactions due to Hymenoptera venom allergy. But, systemic and large local reactions can be observed, especially during the build-up phase of VIT. We evaluated the safety of conventional and ultra-rush build-up protocols. MATERIALS AND METHODS Two protocols in 71 patients (39 conventional and 32 ultra-rush protocols) with honeybee and wasp venom allergy were evaluated retrospectively. Patients were diagnosed and selected for VIT according to the criteria established by the European Academy of Allergy and Clinical Immunology. The severity of systemic reactions was evaluated according to the criteria of Mueller. RESULTS Build-up phases were tolerated in 66.2% (n = 47) without any reaction. Allergic adverse reactions were observed in 33.8% (n = 24): large local reactions 22.5% (n = 16) and systemic reactions 11.3% (n = 8). There was no significant difference in the number of adverse reactions comparing patients receiving conventional and ultra-rush protocol. In addition, no association was found between allergic adverse reactions and the following factors: sex, previous systemic sting reactions, honeybee and wasp venom extract. CONCLUSION We found that both protocols were tolerated in patients with honeybee and wasp venom allergy. Ultra-rush protocol will be preferred for patients and clinicians because of its advantages in terms of time and costs.KEY MESSAGESVIT is the only curative treatment method that reduces the risk of severe reactions after a bee sting and improves the quality of life in patients with Hymenoptera venom allergy.Ultra-rush VIT protocol has advantages such as few injection and time savings.Both ultra-rush and conventional VIT are safe treatments to prevent potentially life-threatening reactions in patients with honeybee and wasp venom allergy.

Abstract
PURPOSE Nasal irrigation is recommended as add-on therapy in patients with intermittent allergic rhinitis (AR). We aimed to evaluate the clinical efficacy of adding hyaluronic acid (HA) or normal saline solution (NSS) to nasal corticosteroid (NC) therapy as add-on therapy in improving quality of life and reducing nasal symptom scores of children with intermittent AR compared to NC therapy. METHOD In this 28-day long, open-label, randomized controlled trial, one puff of NC was administered once a day through both nostrils of 76 children with SAR (6-12 years old), whose Total Nasal Symptom Score (TNSS) was ≥ 4. Twenty-six patients received NC only (Group 1); 24 patients received NSS (Group 2), and 26 patients received HA (Group 3) twice a day by means of nasal douche device. Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) and TNSS were measured as subjective parameters, and nasal eosinophil count (NEC) in nasal cytology, nasal airflow (NAF), and resistance were measured as objective parameters. RESULTS No significant difference was found in post-treatment between groups in terms of TNSS, PRQLQ, and NEC values. Mean values of post-treatment left NAF of the groups were significantly different (p = 0.030), and the mean value of Group 3 was the highest (mean ± SD = 247.62 ± 155.8 ccm/sn). In comparing pre- and post-treatment intragroup mean total NAR (TNAR) values, a statistically significant decrease was recorded only in group three (p = 0.025). CONCLUSION The addition of HA to NC as an adjunct therapy in children with intermittent AR has limited beneficial effects in our study and deserves further investigation. TRIAL REGISTRY The clinical trial registration number ID:NCT04752956.

Abstract
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare but life-threatening multisystem adverse reaction to a medication, with vancomycin being one of the most common cause reported. We present the HLA analysis of a pediatric patient who developed DRESS related to vancomycin and compared the results with the available literature. With further data, the use of pretreatment HLA analysis to prevent vancomycin related DRESS may be a valuable option in the near future.

Abstract
BACKGROUND/AIM In this study, we aimed to assess the clinical and immunological findings of our patients with common variable immunodeficiency (CVID). MATERIALS AND METHODS We analyzed the records of 31 adult patients with CVID (12 females, 19 males). The patients were classified into clinical and immunophenotypic subgroups for statistical comparisons. RESULTS Our patients had some clinical signs in considerable frequencies, such as low body weight (45.2%), urinary tract infections (41.9%), various dermatoses (35.5%), and oral aphthae (32.3%). The histological findings in the biopsy specimens of the gastrointestinal tract (nodular lymphoid hyperplasia, villous atrophy, and lymphocytic infiltrates at mucosa) were significantly associated with splenomegaly, hepatomegaly, or low body weight (P = 0.005, 0.045, and 0.007, respectively). The patients with low CD4/CD8 ratios had lower IgG levels and a lower percentage of CD19+ B cells, but a higher percentage of activated T cells (P = 0.023, 0.011, and 0.028, respectively). CONCLUSION In adults with CVID, there existed some clinical signs at considerable frequencies, but these are not overemphasized in the literature. The CD4/CD8 ratio is an important factor in antibody production and the clinical presentation of CVID. It seems that the adaptive immune system is on alert and subclinical immune activation insidiously continues in patients with CVID.

Abstract
AIMS To determine the frequency, characteristics and risk factors of cardiac device infections in the Isala Hospital. METHODS We retrospectively studied all patients who underwent cardiac device procedures performed in the cardiac catheterisation lab and the operating room from 2010 to 2012. All patients who developed a cardiac device infection were reviewed for its characteristics. RESULTS 31/2026 patients developed a cardiac device infection (1.5 %). One (3.2 %) patient died within 30 days of hospitalisation. Device infection rates for procedures in the catheterisation lab and operating room were similar (p = 0.60). Positive cultures were present in 27/31 (87 %) cases. These consisted predominantly of micro-organisms that are part of the skin flora (84 %). The mean time between device procedure and infection was 14 ± 21 months (range 0-79). Cardiac device infection was significantly associated with device revision, (65 % were revisions in patients with device infection vs. 30 % revisions in patients without device infection, p = 0.011) and placement of a left ventricular lead in pacemaker implantations (59 % of patients with vs. 51 % of patients without device infection, p < 0.001). CONCLUSION The frequency of cardiac device infection was 1.5 % with a mortality of 3.2 % within 30 days, which is lower compared with other registries. Cardiac device infections were associated with device revisions and placement of left ventricular leads in pacemaker implantations.

Abstract
Atrial fibrillation (AF) is associated with short-term mortality after ST-elevation myocardial infarction (STEMI), but there is limited data on the temporal association between AF and mortality after STEMI. A total of 830 patients were included (age: 62 ± 12 years, 76 % male). Patients with new-onset AF < 30 days after STEMI were divided among three subgroups: AF on the day of admission, AF 24–72 h and AF > 72 h after admission. Thirty-day mortality was assessed by telephone and via the municipal population registry. Twenty patients died < 30 days after admission. In 41 patients, AF was detected on the day of admission, in 14 patients 24–72 h after admission and in 18 patients > 72 h after admission. Mortality was higher in patients with AF on the day of admission (7.3 vs 2.2 %, p = 0.036) and 24–72 h after admission (14.3 vs 1.4 %, p < 0.001), but not in patients with AF > 72 h after admission (0 vs 1.1 %, p > 0.999). Age (odds ratio (OR) 1.123, p < 0.001), Killip class (adjusted OR 8.341, p < 0.001), AF on the day of admission (OR 3.585, p = 0.049) and 24–72 h after admission (OR 11.515, p = 0.003) were, amongst other variables, associated with an increased 30-day mortality. In conclusion, only new-onset incident AF during the first 72 h after admission was associated with 30-day mortality in STEMI patients.

Abstract
BACKGROUND We aimed herein to investigate the killer-cell immunoglobulin-like receptor (KIR) genes and human leukocyte antigen (HLA)-C alleles in patients with common variable immunodeficiency (CVID), and to reveal their differences from those in healthy population. METHODS In all, 18 patients who have been diagnosed with CVID and 15 living donors of kidney transplant recipients were enrolled in the study. Polymerase chain reaction-sequence-specific primer (PCR-SSP) typing method was used in molecular genetic analysis. The frequencies of the genes in the study groups were statistically compared with each other using chi-square or Fisher exact tests, whichever were appropriate. RESULTS Although there was no significant difference between both study groups with respect to distribution of KIR and HLA-C2 group genes, HLA-Cw7 allele frequency in patients with CVID was significantly lower than that in healthy population (P = 0.008). CONCLUSION This present study results support that HLA-Cw7 allele, an inhibitor of KIR ligand, may play a role in the pathogenesis of CVID.

Abstract
Hyperthyrotropinaemia, in which normal levels of T4 occur in association with raised thyroid stimulating hormone (TSH), is usually picked up on neonatal screening. High TSH level can continue for a long time in some of the cases. There is no consensus concerning the follow-up or treatment plan for hyperthyrotropinaemia. In this study, results of a 4-year follow-up of 36 cases who had been medically treated are discussed. Low-dose (5 microg/kg/day) L-thyroxin treatment was carried out in 36 cases that had 5 mU/l or higher TSH and showed exaggerated response to TRH test. Dose was decreased to 2-3 microg/kg/day in 24 of these patients during 6 months follow-up. The drug was stopped in three cases because of the development of biochemical hyperthyroidism. Denver developmental assessment test was applied to all cases at the end of the third year. All patients showed a normal development in relation to their age. According to our results, cases with hyperthyrotropinaemia need to be followed regularly for a long time and a need for low-dose L-thyroxin treatment may exist at ages varying from patient to patient.

Abstract
The purpose of this study was to measure and compare the colour stability of three porcelain repair materials (Charizma, Clearfil and Silux Plus) with an all-ceramic material following accelerated ageing. Three composites and one ceramic control were subjected to accelerated ageing for a period of 300 h. Initial specimen colour parameters were determined in the Commission International de I'Eclairage Lab (CIELAB) colour order system with a colorimeter. Colour changes were calculated before (DeltaE) and after 300 h of accelerated ageing (DeltaE*). Colour difference data were subjected to one-way analysis of variance (anova) followed by Duncan's test to examine the interaction between material and time interval of ageing. There were no significant difference between DeltaL values of Porcelain-Charizma and Porcelain-Silux Plus. All mean DeltaL* values were negative after 300 h ageing. Porcelain-Silux Plus demonstrated the highest DeltaL* of the investigated groups. There were significant differences between baseline 300-h aged specimens with respect to Deltaa*, Deltaa for either of the investigated materials. For Silux Plus, Deltaa and Deltaa* values were significantly higher than the others. Significant differences were observed between baseline and 300-h values for Deltab and Deltab*. Deltab and Deltab* values were significantly higher for Silux Plus. There were significant differences between baseline and 300-h values of colour difference, DeltaE, DeltaE*. Highest DeltaE* value was obtained using the microfilled composite, Silux Plus. Lowest value of DeltaE was recorded with the hybrid composite, Charizma.

Abstract
This study was conducted to find out if smoking has an effect on the results of combination therapy with vitamin E and colchicines in patients with early-stage Peyronie's disease (PD). A total of 58 potent patients suffering from early-stage PD were included in the study (mean age 47.3 years, range 25-73 y). The time from onset of the disease was <6 months and no patient had ED. The patients with severe fibrotic or calcified plaques were not included in the study. Of the patients, 36 were smokers (Group 1) and 22 were non-smokers (Group 2). All the patients received vitamin E (800 IU daily) and colchicines (1 mg daily) for 6 months. Follow-up ranged from 5 to 13 months (mean 10.3 m). The combination therapy was effective and well tolerated in both groups. There were no significant differences between the two groups according to age, disease duration, related disease (diabetes, hypertension, hypercholesterolemia, and hypertriglyceridemia), plaque sizes, and plaque numbers. The resolution in pain and increase in penile curvature and plaque size were similar rates in both groups (p > 0.05), while decrease in penile curvature and plaque size were higher in Group 2 (p < 0.05). No patient discounted the therapy due to side effects. The oral combination therapy with vitamin E and colchicines appears to be an effective procedure in patients with early-stage PD and smoking may have worsening effects on the treatment results.

Abstract
PURPOSE To determine the long-term results of the DPVL for the treatment of venous impotence. PATIENTS AND METHODS The long term results of DPVL in 134 patients were interviewed. The mean age was 39.2 (range 21-72). Power color doppler imaging, pharmacocavernography/dynamic cavernosometry were performed. Postoperatively, all the patients were controlled in the 6th month, first year and, if possible, once a year. The mean follow-up was 54.8 (14-76) months. Postoperative outcomes were classified into three groups: complete spontaneous erection (CR), response to pharmacotherapy (PR) or no satisfactory improvement (NR). RESULTS The short-term success in the 6th month according to above mentioned was 38.8%, 18.6% and 42.5%; and in the first year was 19.4%, 14.9% and 65.6% respectively. The result in 35 patients whose follow-up was at least 5 years (mean 67 months) was 11.4%, 14.3% and 74.3% respectively. Positive prognostic factors were preoperative age <40, duration of erectile dysfunction <2 years, non-smoker patients, non neurogenic disease and distal disease. With all these parameters present, long-term success (CR, PR) rose from 33.6% to 55.9% (P < 0.001). CONCLUSIONS Long-term success for unselected patients undergoing DPVL is disappointing; however, careful patient selection significantly improves long-term results.

Abstract
Titanium has become a material of great interest in prosthodontics in recent years because of its excellent biocompatibility, corrosion resistance and desirable physical and mechanical properties. In this study, we determined the influence of dental cements on the passivation of titanium. We developed experimental electrodes that associate titanium and dental cements. Polarization resistance of titanium electrodes has been determined for uncovered metal and electrodes covered with five different dental cements. Coverage with zinc eugenate led to more resistance to corrosion, but fluorinated composite such as glass-ionomer and zinc phosphate coverage increased the corrosion susceptibility.

Abstract
OBJECTIVES To determine the risk factors for penile prosthesis infection. METHODS The records of 135 penile prosthesis implantation in 127 patients were reviewed. Of the 135 prothesis, 115 were malleable, 12 were self-contained and 8 were inflatable. Of these procedures, 111 were primary, 9 were primary with reconstructions and 15 were secondary. Mean follow-up was 47 months (minimum 6 months). All of the reconstructions were penile plications or plaque excisions for Peyronie's disease. RESULTS The ratio of penile prosthesis infection was 8.89%. Secondary implantation, paraplegia, non-controlled diabetes mellitus (p < 0.001) and surgeon's inexperience (p < 0.05) were detected as the risk factors for penile prosthesis infection. But age, smoking, alcohol consumption, obesity, atherosclerosis, presence of diabetes mellitus (DM), history of penile surgery, simple penile reconstruction, type of the erectile dysfunction (ED), type of the penile prostheses and incision and were not found as the risk factors (p > 0.05). CONCLUSIONS Paraplegie, non-controlled diabetes mellitus, secondary implantation and surgeon's inexperience appear to be the risk factors for penile prosthesis infection. In secondary implantation, longer operation time is detected as a factor increasing the risk of penile prosthesis infection. For these patients, careful preoperative preparation, more attention to perioperative antisepsis and postoperative follow-up are required. Since it has been determined that surgical experiences decrease the complication rate, these patients should be operated by experienced surgeons.

Abstract
In this study, we aimed to detect whether or not visualising ureter and ureteropelvic junction (UPJ) preoperatively is necessary in adult patients who have primer UPJ obstruction. Between January 1995 to June 1999, 46 renal units in 45 patients with primer UPJ obstruction were evaluated. The patients were separated into 2 groups. In group 1, intravenous pyelography (IVP) and renal scintigraphy were performed to 17 renal units preoperatively. In group 2, in addition to these methods, either retrograde pyelography (RGP) or antegrade pyelography (AGP) were performed to 29 renal units. Renal/bladder sonogram was used in patients with poor renal function in IVP or in renal scintigraphy. All the operations were performed through a flank incision. In group 2, additional information was gained for 8 (27.5%) of the renal units preoperatively. No additional information for this group found intraoperatively. In group 1, we found additional information in 4 (23.53%) of the units intraoperatively. All the pathologies in both groups were corrected intraoperatively. Double-J (D-J) stent was used in 6 (35.29%) of the units in group 1 and 8 (27.58%) of the units in group 2 intraoperatively (p > 0.05). In group 2, 4 (13.79%) preoperative complications were seen due to RGP and they were treated either medically or conservatively. In the early postoperative period, a complication observed in 1 (5.88%) of the patients in group 1 and 1 of the patients in group 2 (3.44%) (p > 0.05). The first patient was treated with inserting D-J and the latter one was treated conservatively. In the 3rd postoperative month, success rate was found to be 94.11% in group 1 and 96.55% in group 2 (p > 0.05). Additional pathologies in adult patients with primer UPJ obstruction can be corrected intraoperatively through a flank incision. Therefore, imaging of ureter and UPJ may not be necessary in these patients.

Abstract
The neutral zone is defined as the area where the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. In this study records of neutral zones of 30 edentulous patients were used to establish the relation between teeth arrangement according to neutral zone principles and teeth arrangement according to crest of ridge. These 30 patients were classified according to their ages, edentulous periods and denture experience. The results have shown that the lower molars were positioned a little bit closer to lingual with respect to crest of ridge; premolars were positioned either close to crest of ridge or they were coincided on it. In the anterior zone, the teeth were in accordance with known principles of positioned of anatomic landmarks.

Abstract
An experience with 103 children treated with extracorporeal shock wave lithotripsy (ESWL) is reviewed in this report. The success rate was 63%. The stone volume was of major importance for the result. There was a continuous decrease in success rate with increasing stone size. It was also shown that stone-free rates decreased with an increasing number of stones. Short-term complications were minor and hospitalization times were short. It is concluded that ESWL is a first-choice treatment in children with urinary calculi smaller than 200 mm2 in size.

Abstract
Stress and strain patterns around two rigid implant designs used as an abutment were compared and the displacement of natural teeth was investigated. The finite-element method was utilized to determine the stress and strain distributions. The results were evaluated in terms of the maximal tensile and compressive stress and strain in the bone around the abutment tooth and implants. The results indicated that the ITI 1 (hollow screw) implant led to high stress concentrations particularly in the apical region. The stress-transferring characteristics of ITI 2 (solid screw) implant were found to be more suitable than were those of ITI 1.
