Traumatic masturbation and erectile dysfunction: A matched case-control study.

OBJECTIVE: To identify atypical masturbatory behaviors (AMB) and to reveal their effects on both sexual and masturbational erection hardness in men with erectile dysfunction (ED). METHODS: Patients with ED and healthy controls were questioned about their masturbation habits. Accordingly, "rubbing in a prone position," "pressure on penis," and "masturbation through clothes" were included in the traumatic masturbation syndrome (TMS) group. Erection hardness score (EHS) is used to measure the erectile functions during masturbation (mast), foreplay (presex), and sexual intercourse (sex), separately. RESULTS: The data of 448 participants, 266 (59%) from the patient group, and 182 (41%) from the control group were analyzed. The mean ages were 30 years in both groups (p = 0.734). The rate of "rubbing in a prone position" and "penile pressure" while masturbating was higher in patients than the controls (10.2% vs. 6%, p = 0.024 and 8.6% vs. 3.3%, p = 0.0002, respectively). Patients had 2.2-fold (odds ratio, 2.21; 95% confidence interval, 1.40-3.47; p = 0.001) increased risks of having at least one AMB, compared with controls. In the secondary analysis, the patient group was divided into 2 subgroups according to having TMS (ED + TMS) or not (ED). The percentage of patients with EHS≥3 during masturbation was higher than those during sex and presex in the "ED + TMS" group (60.2%, 38.8%, and 37.2%, respectively, p = 0.0001; n = 98). Comparing the percentage of patients with EHS≥3 during mast, presex, and, sex was found to be similar in the "ED" group (58.9%, 56.5%, and 56%, respectively, p = 0.753; n = 168). CONCLUSION: Atypical masturbatory behaviors are more common in young men presenting with erectile dysfunction. These patients have higher erection hardness scores during masturbation compared to partnered sex.

Endoscopic treatment of symptomatic VUR disease after the renal transplantation: analysis of 49 cases.

BACKGROUND: To evaluate the outcome of endoscopic treatment for symptomatic vesicoureteral reflux (VUR) disease in renal transplantation patients and to determine the factors that were associated with the success rate of the treatment. METHODS: A total of 121 symptomatic VUR diseases diagnosed between 2014 and 2018 in 3560 renal transplant patients. The results of 49 VUR cases that presented with febrile urinary tract infection (UTI) and were hospitalized for antibiotic treatment were included in the study. Reflux was detected by voiding cystourethrogram and treatment was performed by endoscopic Deflux® injection. The result of endoscopic treatment was evaluated clinically by 3 months periods. RESULTS: The mean time between transplantation and endoscopic treatment was 59.6 (5-132) months, and the mean follow-up period after the endoscopic treatment was 14 (6-48) months, respectively. The success rate after the first injection was 59.1% (n = 29) and 67.3% (n = 33) after the second injection. One patient developed anuria, one patient febrile UTI and four patients developed minimal macroscopic hematuria after the procedure. CONCLUSIONS: Endoscopic treatment of symptomatic VUR in transplanted kidney is a safe and feasible procedure. The amount of bulking agent or duration between the transplantation and diagnosis of VUR does not have any impact on the success of the treatment. However, the younger age of the patients and the female gender seem to have a positive effect on the outcome of the procedure.

Safety and efficacy of PNL vs RIRS in the management of stones located in horseshoe kidneys: A critical comparative evaluation.

AIM: To assess the efficacy and safety of two different techniques (Percutaneous nephrolithotomy (PNL) vs Retrograde intrarenal surgery (RIRS)) in the management of stones in patients with horseshoe kidneys (HSK). PATIENTS AND METHODS: Departmental files of 88 cases with radiopaque kidney stones in horseshoe kidneys undergoing two different approaches (PNL vs RIRS) were evaluated with respect to the success and complication rates of in a retrospective manner. In addition to the factors related with the procedures (success and complication rates, additional procedures), patient and stone characteristics were all well evaluated. Findings obtained in both groups were evaluated in a comparative manner with respect to the statistical significance. RESULTS: Stone free rates were comparable in both groups after 1-week period (81.6% PNL vs 80% RIRS). As well as 3 months evaluation (84.2% PNL and 82.0% RIRS). The percentage of the cases with residual fragments (> 4 mm) were similar in both groups and while all PNL procedures were completed in one session, mean number of RIRS sessions was higher (1.22 ± 0.05). Mean duration of the procedure was slightly higher in RIRS group and based on Clavien scoring system, despite a higher risk of Hb drop noted in patients treated with PNL, all complication rates were found to be similar in both groups. CONCLUSION: Our results demonstrate that of the available minimally invasive treatment alternatives, both PNL and RIRS could be safe and effective alternatives for renal stone removal in patients with HSK.

Critical evaluation of the overactive bladder and urgency urinary incontinence association with obstructive sleep apnea syndrome in a relatively young adult male population.

AIMS: To evaluate the prevalence of Overactive Bladder (OAB) and Urgency Urinary Incontinence (UUI) in males with Obstructive Sleep Apnea Syndrome (OSAS) using the OSAS grading system. METHODS: A total of 194 patients who underwent Polysomnography (PSG) were included in our prospective cross sectional study. Patients were divided into four groups according to Apnea-Hypopnea Index (AHI). Group 1, 35 patients with normal AHI (<5) as a control group; Group 2, 47 patients with mild OSAS (AHI ≥5 and <15); Group 3, 51 patients with moderate OSAS (AHI ≥15 and <30); Group 4, 61 patients with severe OSAS (AHI ≥30). Over Active Bladder (OAB-V8), ICIQ-SF, and IPSS questionnaires were filled out for all patients. Prevalence of OAB, UUI, nocturia, and scores of OAB-V8, ICIQ-SF, IPSS were compared between the study groups. The statistical analysis was adjusted by the demographics of age and BMI. RESULTS: The mean age was 44.6 ± 11.2 years, and the mean BMI was 29.9 ± 4.9 within the whole study group, and both were statistically different between the groups. The scores of OAB-V8 (P = 0.298), ICIQ-SF (P = 0.392), IPSS total, IPSS storage, and IPSS voiding (P = 0.268, P = 0.380, P = 0.167, respectively), the prevalence of OAB (P = 0.078), UUI (P = 0.423), and nocturia (P = 0.096) were not statistically different between the study groups. CONCLUSIONS: Our findings demonstrated that there is no increase in prevalence of OAB and UUI in relatively young adult male with OSAS. Furthermore, analysis revealed that the higher OSAS grade does not mean the higher prevalence of OAB.

Renal access in PNL under sonographic guidance: Do we really need to insert an open end ureteral catheter in dilated renal systems? A prospective randomized study.

PURPOSE: To evaluate the true necessity of open end ureteral catheter insertion in patients with moderate to severe pelvicalyceal system dilation treated with percutaneous nephrolithotomy (PNL) under sonographic guidance. PATIENTS AND METHODS: 50 cases treated with PNL under sonographic guidance in prone position for solitary obstructing renal stones were evaluated. Patients were randomly divided into two groups; Group 1: Patients in whom a open end ureteral catheter was inserted prior to the procedure; Group 2: Patients receiving no catheter before PNL. In addition to the duration of the procedure as a whole and also all relevant stages as well, radiation exposure time, hospitalization period, mean nephrostomy tube duration, mean drop in Hb levels and all intra and postoperative complications have been evaluated. RESULTS: Mean size of the stones was 308.5 ± 133.2 mm2. Mean total duration of the PNL procedure in cases with open end ureteral catheter was significantly longer than the other cases (p < 0.001). Evaluation of the outcomes of the PNL procedures revealed no statistically significant difference between two groups regarding the stone-free rates (86% vs 84%). Additionally, there was no significant difference with respect to the duration of nephrostomy tube, hospitalization period and secondary procedures needed, complication rates as well as the post-operative Hb drop levels in both groups (p = 0.6830). CONCLUSIONS: Our results indicate that the placement of an open end ureteral catheter prior to a PNL procedure performed under sonographic access may not be indicated in selected cases presenting with solitary obstructing renal pelvic and/or calyceal stones.

Long Term Outcomes of Laparoscopic and Open Modified Lich-Gregoir Reimplantation in Adults: A multicentric comparative study.

BACKGROUND & OBJECTIVE: Obstructive ureteral pathologies in adult patients are most commonly due to ureteral strictures and secondary to surgical interventions. In this study, we aimed to compare open and laparoscopic modified Lich-Gregoir ureteral reimplantation with regards to outcomes in benign ureteral pathologies in adult patients. METHODS: Between December 2008 and December 2014, 32 open cases and 29 laparoscopic cases were performed as per the data retrieved from surgical databases. All laparoscopic procedures were performed in Bakirkoy Dr. Sadi Konuk Training and Research Hospital(BEAH) and all open ureteral reimplantation procedures in Kartal Dr Lutfi Kirdar Training and Research Hospital(KEAH) and Okmeydani Training and Research Hospital(OEAH). RESULTS: The mean operation time was significantly lower in the group of patients operated with open group (142.5 minutes versus 188.9 minutes; P< 0.0001). The mean duration of follow-up was longer in the laparoscopy group (31 versus 28 months; p< 0.0001). The mean amount of operation associated blood loss was significantly lower in patients operated laparoscopically (93.7 mL versus 214 mL; P< 0.0001). The mean VAS score obtained six hours after surgery was 6.6 ± 0.8 in open group, and 5.8 ± 0.7 in laparoscopic group (p=0.0004). The mean VAS scores measured at post-operative day 1 was 4.5 ± 0.7 in open group and 3.7 ± 0.9 in laparoscopy group. Time required to achieve the pre-operative capability of daily activities was significantly longer in open group (15 ± 1.4 days vs 11 ± 1.4 days; p< 0.0001). CONCLUSION: Despite open techniques provide shorter operation time and laparoscopic techniques require long learning curve, we think that laparoscopic techniques are superior to open ones since that they provide a better post-operative comfort and are better tolerated in terms of complications.

A mesothelioma epidemic in Cappadocia: scientific developments and unexpected social outcomes.

In Cappadocia, Turkey, an unprecedented mesothelioma epidemic causes 50% of all deaths in three small villages. Initially linked solely to the exposure to a fibrous mineral, erionite, recent studies by scientists from Turkey and the United States have shown that erionite causes mesothelioma mostly in families that are genetically predisposed to mineral fibre carcinogenesis. This manuscript reports, through the eyes of one of the researchers, the resulting scientific advances that have come from these studies and the social improvements that were brought about by both the scientists and members of the Turkish Government.

Macrophage activation syndrome in children with systemic juvenile idiopathic arthritis and systemic lupus erythematosus.

Macrophage activation syndrome (MAS) is a hyper-inflammatory disorder secondary to a rheumatic disease such as systemic juvenile idiopathic arthritis (SJIA) and systemic lupus erythematosus (SLE). We aimed to present the characteristics of our pediatric MAS patients. Clinical features, laboratory parameters, treatment, and outcome of 34 patients (28 SJIA; six SLE; 37 MAS episodes) followed at a tertiary health center between 2009 and 2015 were retrospectively reviewed. The median age at MAS onset was 11 years. More SJIA patients had MAS at disease onset than SLE patients (53.6 vs. 16.7 %). Fever, high C-reactive protein and hyperferritinemia were present in all MAS episodes. Rash was less (p = 0.03), and fatigue was more frequent (p = 0.042) in SLE than SJIA patients. All received corticosteroids. Cyclosporine was given in 74.2 % of SJIA-MAS; 66.7 % of SLE-MAS episodes. Intravenous immunoglobulin, anakinra, or etoposide was administered during 67.7; 41.9; 32.3 % of SJIA-MAS and 33.3; 33.3; 50 % of SLE-MAS episodes, respectively. Plasmapheresis was performed during 41.9 % of SJIA-MAS and 33.3 % of SLE-MAS episodes. The mortality rate was 11.8 % (n = 4;3 SJIA, 1 SLE). Hepatosplenomegaly was more frequent (p = 0.005), and plasmapheresis was performed more frequently (p = 0.021) in the patients who died compared to the cured patients. The median duration between symptom onset and admission to our hospital was longer among the patients who died (16.5 vs. 7 days; p = 0.049). Our patients' characteristics were similar to the reported cases, but our mortality rate is slightly higher probably due to late referral to our center. Early diagnosis and effective treatment are crucial to prevent mortality.

Medical Expulsive Therapy Following Shock Wave Lithotripsy in Ureteral Calculi: An Effective Approach for the Improvement of Health-Related Quality of Life.

OBJECTIVE: To evaluate the possible effects of medical expulsive therapy (MET) on the health-related quality of life (HRQOL) of patients undergoing shock wave lithotripsy (SWL) for ureteric stones. METHODS: Eighty patients treated with SWL for ureteric stones were included in this study. Patients were divided into 2 groups; Group 1 received medical therapy only for colic pain and Group 2 received MET in addition to medical therapy. Patients requiring DJ stenting and auxiliary measures after SWL procedure were excluded. The remaining 54 patients were further evaluated (Group 1: n = 26, Group 2: n = 28) and followed up during the 4-week period for analgesic requirement, number of renal colic attacks, emergency department (ED) visits and the HRQOL scores by using EQ-5D index and EQ-5D visual analogue scale (VAS) values. RESULTS: During the 4-week follow-up period, cases undergoing SWL only required significantly higher amount of analgesics. In addition to the lower number of renal colic attacks and ED visits, EQ-5D index and EQ-5D VAS values also demonstrated higher mean values in patients undergoing SWL + MET. CONCLUSION: In addition to the increased spontaneous stone passage rates, MET following SWL for ureteral calculi could increase the HRQOL scores by lowering the number of both renal colic attacks and ED visits along with decreased analgesic need.

The effects of stress incontinence surgery on sexual function and life quality of women.

OBJECTIVE: To evaluate Transobturator tape (TOT) and Burch colposuspension procedure's effects on sexual functions and life quality. MATERIALS AND METHODS: A total of 81 patients who underwent TOT (n = 49) or Burch (n = 32) with stress incontinence were included in this prospective study. Preoperatively and at postoperative 6 month follow up pad and stress tests, physical examinations, Female Sexual Function Index (FSFI), International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), Urinary Distress Inventory (UDI-6), Incontinence Impact Questionnaire (IIQ-7) questionnaires were performed. Patient Global Impression of Improvement (PGI-I) questionnare was added postoperatively. RESULTS: According to stress test, success rate was found to be 69% and 45%, in the TOT and Burch groups respectively. Pad test decreased in both groups (p < 0.05). PGI-I scores was higher in the TOT group when compared to Burch group (p = 0.031). ICIQ-SF scores were improved in both TOT (p < 0.0001) and Burch groups (p < 0.012). IUDI-6 and IIQ-7 scores improved only in TOT group. Total FSFI scores did not change in both groups but only in TOT group sexual desire improved. Total FSFI scores did not change in patients that were successful and unsuccessful according to the stress test in both TOT and Burch groups (p < 0.05). CONCLUSIONS: TOT and Burch procedures have no effect on the sexual functions. However TOT improved life quality of patients.

Emergency management of ureteral stones: Evaluation of two different approaches with an emphasis on patients' life quality.

OBJECTIVES: To evaluate the emergency management of obstructing ureteral calculi with two different techniques (SWL and URS) with an emphasis on patients life quality. METHODS: A total of 80 patients presenting with acute colic pain due to a single obstructing ureteral stone were treated within 24 hours following the onset of pain with two different approaches in a randomized manner. Patients requiring DJ stent placement and/or auxiliary measures after both procedures were excluded and the remaining 65 patients were evaluated [Group1: ESWL (n = 34); Group 2: URS (n = 31)]. Patients were followed during 4-weeks period with respect to the analgesic requirement, number of renal colic attacks and emergency department visits along with the HRQOL scores. RESULTS: While 26 patients treated with URS (83.9%) were stone-free, 24 cases in SWL were stone-free (70.6%) after 4 weeks. Evaluation of the cases during this follow-up period demonstrated that cases undergoing SWL required significantly higher amount of analgesics when compared with URS group (p < 0.001). In addition to the lower mean number of renal colic attacks and emergency department visits in URS group; both the mean HRQOL in terms of EQ-5D index and mean EQ-5D VAS values were also significantly higher in these cases when compared with the cases tretaed with SWL. CONCLUSIONS: Due to the negative impact of stone related events after emergency SWL on patients HRQOL, emergency URS may be applied more effectively with the advantages of prompt fragmentation of the calculi along with the immediate relief of obstruction and pain.

Does extracorporeal shock wave lithotripsy cause hearing impairment in children?

PURPOSE: We evaluated the possible effects of noise created by high energy shock waves on the hearing function of children treated with extracorporeal shock wave lithotripsy. MATERIALS AND METHODS: A total of 65 children with normal hearing function were included in the study. Patients were divided into 3 groups, ie those becoming stone-free after 1 session of shock wave lithotripsy (group 1, 22 children), those requiring 3 sessions to achieve stone-free status (group 2, 21) and healthy children/controls (group 3, 22). Extracorporeal shock wave lithotripsy was applied with patients in the supine position with a 90-minute frequency and a total of 2,000 shock waves in each session (Compact Sigma, Dornier MedTech, Wessling, Germany). Second energy level was used with a maximum energy value of 58 joules per session in all patients. Hearing function and possible cochlear impairment were evaluated by transient evoked otoacoustic emissions test at 1.0, 1.4, 2.0, 2.8 and 4.0 kHz frequencies before the procedure, 2 hours later, and 1 month after completion of the first shock wave lithotripsy session in groups 1 and 2. In controls the same evaluation procedures were performed at the beginning of the study and 7 weeks later. RESULTS: Regarding transient evoked otoacoustic emissions data, in groups 1 and 2 there was no significant alteration in values obtained after shock wave lithotripsy compared to values obtained at the beginning of the study, similar to controls. CONCLUSIONS: A well planned shock wave lithotripsy procedure is a safe and effective treatment in children with urinary stones and causes no detectable harmful effect on hearing function.

Biochemical markers of glucose metabolism may be used to estimate the degree and progression of iron overload in the liver and pancreas of patients with ß-thalassemia major.

The use of cardiac and hepatic T2* MRI measurements to predict the amount of iron accumulation in these organs has been studied extensively and was suggested to be used reliably. However, it may not be practical to screen other organs with MRI related to economical issues and also the prolonged imaging durations. Herein, we aimed to test the use of fasting glucose, fasting, and postprandial insulin, homeostasis model assessment-insulin resistance (HOMA-IR) (calculated as insulin (µIU/ml) × glucose (mg/dl)/22.5), and homeostasis model assessment B score (HOMA-B) (calculated as insulin (µIU/ml) × 20/glucose (mg/dl) - 3.5) to estimate the tissue iron measured with MRI. A total of 37 patients with ß-thalassemia major (BTM), age 20.8 ± 6.3 years (7.1-36.8), were enrolled. MRI measurements were done concomitantly to the biochemical tests for glucose metabolism. A positive correlation between HOMA-IR and hepatic iron loading and a negative correlation between pancreatic T2* and fasting blood glucose were found. A positive correlation was found between fasting insulin levels and pancreatic R2* measures. Additionally, a correlation was detected between cardiac and pancreatic iron accumulations. In centers where T2*/R2* MRI facilities are unavailable, fasting insulin, fasting glucose, and HOMA-IR measurements may be used to predict iron overload and may urge the physician for MRI assessment in case of a deterioration in these biochemical tests. Since hepatic iron loading correlated with insulin resistance development, the insulin resistance among patients with BTM may partially be explained with decreased hepatic insulin clearance from heavily iron-loaded liver.

Evaluation of sexual function in patients submitted to ureteroscopic procedures.

OBJECTIVE: We aimed to evaluate the possible effects of ureteroscopic procedures on the sexual function of both genders. MATERIALS AND METHODS: A total of 102 sexually active cases (60 male, 42 female) undergoing ureteroscopic procedures were included in this study. Sexual function has been evaluated in detail by using International Index of Erectile Function (IIEF) in male and Female Sexual Function Index (FSFI) forms in female cases both before and 1-month after the procedures. Pre-and postoperative data were evaluated in a comparative manner. RESULTS: The pre-and postoperative mean IIEF scores were 57.86 ± 2.26 and 54.57 ± 2.48 (p = 0.19) in males and the mean FSFI scores were 13.58 ± 1.46 and 14.46 ± 1.52 (p = 0.41), respectively in females. Evaluation of these values showed that regarding the effects of this procedure on male cases although the total scores for sexual function were not influenced it was observed a significant reduction in the intercourse satisfaction subdomain (IIEF-IS) in males (p < 0.05). In female cases however, unlike the male cases no statistically significant alterations with respect to these scores were noted (p = 0.418). CONCLUSION: Ureteroscopic interventions could have some adverse effects on the sexual function particularly in male cases. However, it is clear that further prospective studies in both genders with large population of cases are certainly needed in order to outline this unresolved but important subject.

Shock Wave Lithotripsy in Ureteral Stones: Evaluation of Patient and Stone Related Predictive Factors.

PURPOSE: To evaluate the patient and stone related factors which may influence the final outcome of SWL in the management of ureteral stones. MATERIALS AND METHODS: Between October 2011 and October 2013, a total of 204 adult patients undergoing SWL for single ureteral stone sizing 5 to 15 mm were included into the study program. The impact of both patient (age, sex, BMI,) and stone related factors (laterality, location, longest diameter and density as CT HU) along with BUN and lastly SSD (skin to stone distance) on fragmentation were analysed by univariate and multivariate analyses. RESULTS: Stone free rates for proximal and distal ureteral stones were 68.8% and 72.7%, respectively with no statistically significant difference between two groups (p=0.7). According to univariate and multivariate analyses, while higher BMI (mean: 26.8 and 28.1, p=0.048) and stone density values (mean: 702 HU and 930 HU, p < 0.0001) were detected as statistically significant independent predictors of treatment failure for proximal ureteral stones, the only statistically significant predicting parameter for the success rates of SWL in distal ureteral stones was the higher SSD value (median: 114 and 90, p=0.012). CONCLUSIONS: Our findings have clearly shown that while higher BMI and increased stone attenuation values detected by NCCT were significant factors influencing the final outcome of SWL treatment in proximal ureteral stones; opposite to the literature, high SSD was the only independent predictor of success for the SWL treatment of distal ureteral stones.

Stone size and quality of life: A critical evaluation after extracorporeal shock wave lithotripsy.

OBJECTIVES: To evaluate the quality of life (QoL) of the patients after extracorporeal shockwave lithotripsy (ESWL) on a treated stone size related basis. METHODS: 90 patients undergoing ESWL for kidney stones were divided into three groups; Group 1 (n: 30, ≤ 10 mm), Group 2 (n: 28, 11 mm- ≤ 20 mm) and Group 3 (n: 32, 20- 25 mm). During 3- months follow-up, outcome of the procedure, number of cases with emergency department visits, analgesic required, re-tretatment rates, additional procedures and the changes in the QoL were evaluated. RESULTS: the number of emergency department visits and mean analgesic need; re-treatment rates and additional procedures were significantly higher in Group 3. Evaluation of the QoL scores in three groups showed that cases with larger stone still had lower scores during 3-month evaluation. CONCLUSIONS: Stone size could help us to predict the possible impact of ESWL on the QoL and depending on the size of the stone treated, a well planned indication and effective management possibly by an experienced urologist could limit the changes in the QoL of the patients.

A novel mutation in protein C gene (PROC) causing severe phenotype in neonatal period.

Homozygous protein C deficiency is among rare causes of thrombophilia. Herein, we present a neonate with purpura fulminans, disseminated intravascular coagulation and severe intracranial hemorrhage who was found to have plasma protein C level of 4%. The molecular work-up revealed a novel homozygous mutation of T903C (amino acid position Leu 270 Pro) located in a catalytic domain region of PROC gene. Asymptomatic course in patients with low but measurable levels of protein C levels has been reported, which is different than observed in our patient who had a very severe course despite plasma protein C level of 4%.

Childhood acute lymphoblastic leukemia in the Middle East and neighboring countries: a prospective multi-institutional international collaborative study (CALLME1) by the Middle East Childhood Cancer Alliance (MECCA).

BACKGROUND: Little is known about childhood ALL in the Middle East. This study was undertaken by MECCA as initial efforts in collaborative data collection to provide clinical and demographic information on children with ALL in the Middle East. PROCEDURE: Clinical and laboratory data for patients with ALL between January 2008 and April 2012 were prospectively collected from institutions in 14 Middle East countries and entered into a custom-built-database during induction phase. All laboratory studies including cytogenetics were done at local institutions. RESULTS: The 1,171 voluntarily enrolled patients had a mean age of 6.1 ± 3.9 years and 59.2% were boys. T-ALL represented 14.8% and 84.2% had B-precursor ALL. At diagnosis, 5.6% had CNS disease. The distribution of common genetic abnormalities reflected a similar percentage of hyperdiploidy (25.6%), but a lower percentage of ETV6-RUNX1 translocation (14.7%) compared to large series reported from Western populations. By clinical criteria, 47.1% were low/standard risk, 16.9% were intermediate risk, and 36% were high risk. Most patients received all their care at the same unit (96.9%). Patients had excellent induction response to chemotherapy with an overall complete remission rate of 96%. Induction toxicities were acceptable. CONCLUSIONS: This first collaborative study has established a process for prospective data collection and future multinational collaborative research in the Middle East. Despite the limitations of an incomplete population-based study, it provides the first comprehensive baseline data on clinical characteristics, laboratory evaluation, induction outcome, and toxicity. Further work is planned to uncover possible biologic differences of ALL in the region and to improve diagnosis and management.

Erionite exposure in North Dakota and Turkish villages with mesothelioma.

Exposure to erionite, an asbestos-like mineral, causes unprecedented rates of malignant mesothelioma (MM) mortality in some Turkish villages. Erionite deposits are present in at least 12 US states. We investigated whether increased urban development has led to erionite exposure in the United States and after preliminary exploration, focused our studies on Dunn County, North Dakota (ND). In Dunn County, ND, we discovered that over the past three decades, more than 300 miles of roads were surfaced with erionite-containing gravel. To determine potential health implications, we compared erionite from the Turkish villages to that from ND. Our study evaluated airborne point exposure concentrations, examined the physical and chemical properties of erionite, and examined the hallmarks of mesothelial cell transformation in vitro and in vivo. Airborne erionite concentrations measured in ND along roadsides, indoors, and inside vehicles, including school buses, equaled or exceeded concentrations in Boyali, where 6.25% of all deaths are caused by MM. With the exception of outdoor samples along roadsides, ND concentrations were lower than those measured in Turkish villages with MM mortality ranging from 20 to 50%. The physical and chemical properties of erionite from Turkey and ND are very similar and they showed identical biological activities. Considering the known 30- to 60-y latency for MM development, there is reason for concern for increased risk in ND in the future. Our findings indicate that implementation of novel preventive and early detection programs in ND and other erionite-rich areas of the United States, similar to efforts currently being undertaken in Turkey, is warranted.

A rare cause of renal colic pain: Chilaiditi syndrome.

Chilaiditi syndrome, first described in 1910 by the radiologist Chilaiditi from Vienna, is the interposition of right colon between liver and right hemi diaphragm. It occurs most often in males and its incidence increases with age. It is often detected incidentally during radiological examination. It's rarely symptomatic; symptoms can differ from mild abdominal pain to severe acute intestinal obstruction. Our case applied to emergency service with right flank pain. There was no calculus or dilatation in the urinary system at non-contrast abdominopelvic computerized tomography. Ascending colon was interposed between liver and diaphragm so that the patient was diagnosed as Chiliaditi syndrome. The patient was treated conservatively and discharged with dietary suggestions by the gastroenterology consultant. The conclusion of this report is that the Chilaiditi syndrome must be considered in differential diagnosis for patients presenting with urinary colic pain symptoms with no urinary pathology on radiologic imaging.
