Abstract
Abstract
Study question
to investigate the effect of total motile sperm (TMS) count, and ovulation induction on clinical pregnancy rate in artificial insemination with donor (AID) cycles.
Summary answer
TMS count is not a predictor of sucess, and natural cycles are as effective as oral ovulation induction in donor inseminations
What is known already
There are inconsistent results regarding the effect of sperm parameters on success rates of artificial insemination with donor (AID). Besides, the use of gonadotropin stimulation for ovulation induction in this category of patients is questionable, and its effectiveness over natural cycles is not yet confirmed in the literature.
Study design, size, duration
Patients who underwent AID cycles at the university-affiliated fertility center-OVO clinic in Montreal, Canada between 2011 and 2015 were retrospectively selected. A total of 4333 AID cycles were performed on 1179 patients, resulting in 744 pregnancies.
Participants/materials, setting, methods
Cycles were divided into 8 groups based on TMS count: <0.5, [0.5-1[, [1-5[, [5-10[, [10-20[, [20-40[, [40-80[, and ≥80. A TMS of 10 to 20 million was selected as a reference level. Ovulation induction was divided into oral stimulation, combined oral and gonadotropin stimulation and gonadotropin-only stimulation, and compared to natural cycles. Regression analysis and a predictive model of clinical pregnancy in AID cycles were generated from patient demographic and cycle characteristics.
Main results and the role of chance
There was no significant difference in positive β-hCG result, clinical pregnancy, multiple pregnancy and miscarriage rates when comparing all ranges of TMS count to a reference of 10 to 20 million. When dividing patients based on the protocol for ovulation induction, clinical pregnancy rate was significantly higher in the gonadotropin-only stimulation group (OR 4.116,[1.379,12.287]) but not in other types of stimulation, as compared to natural cycles. hCG triggering resulted in a similar clinical pregnancy and miscarriage rates, but a higher multiple pregnancy rate when compared to urinary LH testing (7.7% versus 1.3%, p = 0.045). A multivariate logistic regression analysis for predictors of clinical pregnancy accounting for relevant demographic and cycle characteristics was conducted. No significant difference was noted in different ranges of TMS and the groups of ovulation induction. In this model, age was found to be a significant predictor. In particular, with every one-year increase in age, the odds of clinical pregnancy decreases by 6.4% (Adjusted OR 0.936; 95%CI [0.914, 0.958]).
Limitations, reasons for caution
In our study, cycles with TMS count below 1 million are limited. Thus, results should be viewed with caution in this group, without cycle cancellation, since clinical pregnancy can be achieved. Moreover, our results cannot be generalized on infertile couples given the characteristics of our population of interest.
Wider implications of the findings
Minimal or maximal cut-off values for TMS in AID cycles should not be used as indicators for cycle cancellation. Natural cycles are as successful as oral ovulation induction. hCG trigger, unless indicated, should not be used as it is associated with higher risk of multiple pregnancy without increasing clinical pregnancy.

Abstract
Introduction Periodontal diseases are a group of chronic infections that destroy tissues surrounding and supporting the teeth. Data on the anaerobes associated with periodontal infections in Kuwait is lacking. Aim To investigate the target anaerobes associated with chronic periodontitis (CP) in patients admitted to Dental Clinics in Kuwait University Health Sciences Center, Kuwait. Methodology Patients with CP (severe and moderate) were recruited into this study during a period of 15 months. Samples were collected directly from inside the gingival pockets and subjected to semi-quantitative PCR assays. Results A total of 30 patients, stratified into moderate and severe CP and 31 healthy individuals, used as controls, were studied. Nine (30 %) of the 30 patients were in the 50–59-year age group. The detection rate of Aggregatibacter actinomycetemcomitans between the patients (9 : 30 %) versus the controls (5 : 16.1 %) was non-significant (P >0.05). Fusobacterium spp., were detected in all patients versus 29 (93.1 %) controls, (P >0.05). However, four target anaerobes were significantly associated with CP patients; Porphyromonas gingivalis was detected in ten (33.3 %) patients versus two (6.4 %) controls (P <0.0001); Tannerella forsythia 25 (83.3 %) versus 16 (51.6 %) controls (P <0.0001); Parvimonas micra 27 (90 %) versus 16 (51.6 %) controls (P <0.0001) and Treponema denticola, 18 (60 %) versus nine (29 %) controls (P <0.0001), respectively. Prevotella spp. were detected in 27 (90 %) patients and 30 (96.7 %) controls (P>0.5). There was no significant difference in the burden of Prevotella spp. between patients and controls determined by semi-quantitative PCR assays. Conclusion Some (4/7) of the target anaerobes were significantly associated with CP in our study. P. gingivalis was the most strongly associated anaerobe with CP, although not the keystone bacteria, while Prevotella spp. was similar to the healthy controls.

Abstract
Sensory abnormalities are widespread in Autism Spectrum Disorder (ASD). However, their definition is still quite subjective and vague. Here we propose a novel approach for characterization of Autonomic Nervous System responses to sensory stimulation based on electrocardiogram (ECG) assessment. In particular, we develop a preliminary study where autonomic responses of both autistic (ASD = 5) and neurotypical (NT = 5) participants have been evaluated in terms of changes in responsiveness to repeated stimuli. Autonomic control has been estimated via high-frequency heart rate variability (HF-HRV) and low-frequency HRV (LF-HRV). Results show significant differences among groups for the HRV measures (p value = 0.0158), supported by expected changes of HF (p value = 0.0079) and LF (p value = 0.0079) trends over stimulations. We thus conclude that an overall decrease in autonomic arousal can give important insights for devising new habituation metrics in NT and ASD individuals.

Abstract
Background: The benefit of liver transplantation is not only to increase the patient’s lifetime but also for persistent relief of pain and anxiety. Shortage of the organ is the main hindrance of transplantation around the world, leading authorities to pass a general law for the reasonable distribution of organs and come up with the Model for End-Stage Liver Disease (MELD) system which scores the severity of liver disease and risk of mortality in order to detect the mechanism of allocation. Objective: This study aims to assess medical students’ perception of the liver transplant and allocation system. Methods: A cross-sectional survey was carried out among 402 medical students at King Abdulaziz University in Jeddah, Saudi Arabia. Results: The majority of the medical students (84.4%) believed that a successful liver transplant improves both lifetime and quality of life. Most of the students also saw that the minimum survival rate should be five years after transplantation and that the patient should recover to be at least ambulatory, even if restricted by strenuous physical activity. When asked whether urgency or prospect of success defined a successful transplant, most of the students who chose urgency were preclinical (50.7%), while the prospect of success was the dominant answer chosen by students in their clinical years of study (66.1%). Conclusion: The criteria determining the success of a liver transplant include a gain in both lifetime and quality of life. The majority of respondents wanted the capacity to benefit to be considered in the liver allocation system.

Abstract
Abstract
Background and aims
The EMPA-REG OUTCOME trial included patients with type 2 diabetes (T2D) and established atherosclerotic cardiovascular (CV) disease. Empagliflozin reduced the risk of 3-point major adverse CV events (MACE; composite of CV death, myocardial infarction [MI], or stroke) by 14%, CV death by 38% and hospitalisation for heart failure (HF) by 35% vs placebo in analyses of time to first event. We assessed the effect of empagliflozin on all-cause hospitalisation in post-hoc analyses of all (first and recurrent) events.
Materials and methods
Patients were randomised to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo in addition to standard of care. We assessed the effects of empagliflozin pooled vs placebo on first event of all-cause hospitalisation using Cox regression and all (first and recurrent) events of all-cause hospitalisation using a negative binomial model.
Results
A total of 7020 patients were treated (4687 empagliflozin; 2333 placebo, mean [SD] age 63 [9] years, 71% male, 47% with history of MI, 23% with history of stroke, 10% with HF). In this analysis, 1725/4687 (36.8%) empagliflozin patients and 925/2333 (39.6%) placebo patients experienced an event leading to hospitalisation. The adjusted hazard ratio (HR; 95% CI) vs placebo for first all-cause hospitalisation using the Cox regression model was 0.89 (0.82, 0.96; p=0.0033; Figure); In analyses of all (first and recurrent) hospitalisation events, there were 3168 events in the empagliflozin group and 1863 in the placebo group. The adjusted event rate ratio (95% CI) vs placebo was 0.83 (0.76, 0.91; p<0.0001; Figure).
Conclusion
In the EMPA-REG OUTCOME trial, risk reductions with empagliflozin were seen in both first and all hospitalisation events and were numerically more favourable in analyses of all events vs analyses of first events. These analyses expand on the favourable CV effects of empagliflozin by also showing a reduction in the total burden of hospitalisation events in patients with T2D and established CV disease.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) is an emerging bariatric procedure, which has been reported to be safe and effective. This study aims to evaluate the short-term outcome of OAGB and its midterm effects on weight loss and remission of type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS A retrospective review of patients who had undergone OAGB between January 2013 and January 2017 in King Abdulaziz University Hospital, Jeddah, Saudi Arabia, is presented here. Patients' perioperative characteristics, biochemical profile (fasting blood glucose, HbA1c and iron profile) and details on subsequent weight loss in terms of body mass index (BMI) and excess weight loss percentage (EWL%) along with early and late postoperative complications were evaluated. RESULTS Out of the 47 patients who underwent OAGB, 42 were included in this study and completed the 2-year follow-up. Average operative time was 107±21.3 minutes and average length of hospital stay was 2.5±0.53 days. Mean preoperative BMI was 47.6±9.1 kg/m2, and at 1 and 2 years of follow-up, it was 30.5±7.4 and 27.1±5.1, respectively. No mortality, anastomotic leak or bleeding were reported. Most common midterm complication was iron deficiency anemia (n=7/42). Remission of T2DM at 6 months was 80%. Patients with preoperative T2DM for less than 10 years showed better remission (P<0.001). CONCLUSION Our analysis suggests that OAGB is a safe and effective weight loss procedure that carries low perioperative risk and acceptable nutritional complications in the midterm, with a notable remission of T2DM. Preoperative duration of T2DM plays a major role in achieving remission after OAGB.

Abstract
Background Herein we present our experience with laparoscopic common bile duct exploration (LCBDE) in managing common bile duct stones. Methods Data of 129 consecutive patients who underwent laparoscopic cholecystectomy (LC) and LCBDE done at our institutes from April 2011 through June 2016 were prospectively recorded and retrospectively reviewed. Results Since 2011, 3012 laparoscopic cholecystectomy were performed at our institutes, intraoperative cholangiogram (IOC) was done in 295 (9.8%) patients which detected choledocholithiasis in 129 (4.3%) of them. LCBDE was successful to clear the common bile duct (CBD) in 123/129 (95.4%). Six patients underwent postoperative endoscopic retrograde cholangiopancreatography (ERCP) because of incomplete CBD clearance (4 cases), symptomatic stenosed papilla (2 cases). LCBDE was performed in 103 patients via trans-cystic approach and choledochotomy one in 26 patients. In the choledochotomy group, seven patients had primary closure of the CBD, CBD was closed over T-tube in nine patients whereas the remaining 10 patients the CBD was closed over antegrade inserted stent. The median time of hospital stay was 4 (range; 1–15) days. No patients showed retained CBD stones with mean follow up was 9 ± 3.4 months. Conclusion LCBDE is a safe and cost effective option for CBD stones in short-term outcome and can be performed provided proper laparoscopic expertise and facilities are available.

Abstract
This article was migrated. The article was not marked as recommended. Aim: To determine level of knowledge of medical students and recent graduates' physicians regarding the possibility of surgical treatment for obesity. Background: Over the last few decades, the development of bariatric surgery has been observed. Which represents currently the only permanent and comprehensive method for the treatment of obese patients. However, knowledge about the possibility of surgical procedures among general practitioners is not sufficient. That might be due to lack of knowledge about bariatric surgery in university curriculum. Methods: We administered a cross-sectional survey among 298 medical students and recent graduates physicians from King Abdulaziz University. The survey was conducted to evaluate their knowledge regarding methods of surgical treatment of obesity, and to evaluate the amount of information on metabolic surgery provided to students during surgery courses. Result: Theoretical knowledge in the surgical treatment of obesity was possessed by 82% of medical students and 17.4% of interns. Results revealed a low level of knowledge on the possibility of applying metabolic surgery in treating morbid obesity. Most of participants expressed a need to improve their knowledge and favorably expanding the curriculum to include more information on the subject of metabolic surgery. Conclusion: The knowledge and awareness of weight loss surgery among medical student and recent graduates in KAU is inadequate, and need to be improved .

Abstract
Metabolic phenotyping of obese populations can shed light on understanding environmental interactions underpinning obesogenesis. Obesity and its comorbidities are a major health and socioeconomic concern globally and are highly prevalent in the Middle East. We employed nuclear magnetic resonance spectroscopy to characterize the metabolic signature of urine and blood plasma for a cohort of obese (n = 50) compared to non-obese (n = 48) Saudi participants. The urinary metabolic phenotype of obesity was characterized by higher concentrations of N-acetyl glycoprotein fragments, bile acids, lysine, and methylamines and lower concentrations of tricarboxylic acid cycle intermediates, glycine, and gut microbial metabolites. The plasma metabolic phenotype of obesity was dominated by sugars, branched chain amino acids, and lipids, particularly unsaturated lipids, with lower levels of plasma phosphorylcholine and HDL. Serum hepatic enzymes, triglycerides, and cholesterol mapped to specific metabolic phenotypes, potentially indicating the dysregulation of multiple distinct obesity-related pathways. Differences between urine and plasma phenotypes of obesity for this Saudi population and that reported for Caucasian individuals indicate population disparities in pathways relating to ketogenesis (more apparent in the Saudi obese population), dysregulated liver function, and the gut microbiome. Mapping population-specific metabolic perturbations may hold promise in establishing population differences relevant to disease risk and stratification of individuals with respect to discovery of new therapeutic targets.

Abstract
BACKGROUND The aim was to assess the outcome of a total pancreatectomy (TP). METHODS From 1993 to 2010, 56 patients underwent an elective TP for intraductal papillary mucinous neoplasia (n = 42), endocrine tumours (n = 6), adenocarcinoma (n = 5), metastases (n = 2) and chronic pancreatitis (n = 1). Morbidity and survival were analysed. Long-term survivors were assessed prospectively using quality-of-life (QoL) questionnaires. RESULTS Five patients developed gastric venous congestion intra-operatively. Post-operative morbidity and mortality rates were 45% and 3.6%, respectively. An anastomotic ulcer occurred in seven patients, but none after proton pump inhibitor therapy. There were five inappropriate TPs according to definitive pathological examination. Overall 3- and 5-year survival rates were 62% and 55% respectively; five deaths were related to TP (two postoperative deaths, one hypoglycaemia, one ketoacidosis and one anastomotic ulcer). Prospective evaluation of 25 patients found that 14 had been readmitted for diabetes and that all had hypoglycaemia within the past month. The glycated haemoglobin (HbA1c) was 7.8% (6.3-10.3). Fifteen patients experienced weight loss. The QLQ-C30 questionnaire showed a decrease in QoL predominantly because of fatigue and diarrhoea, and the QLQ-PAN26 showed an impact on bowel habit, flatulence and eating-related items. DISCUSSION Morbidity and mortality rates of TP are acceptable, although diabetes- and TP-related mortality still occurs. Endocrine and exocrine insufficiency impacts on the long-term quality of life.

Abstract
Multidrug-resistant Gram-positive bacteria are an increasingly pressing problem in the clinic. Consequently, linezolid, a recently introduced oxazolidinone with Gram-positive activity, was tested in comparison with 10 other antibiotics against 8103 clinically significant Gram-positive cocci by Etest, disk diffusion and Vitek methods. Linezolid demonstrated excellent activities against all isolates. Vancomycin and teicoplanin demonstrated equally excellent activity against almost all isolates. The methicillin-resistant Staphylococcus aureus (MRSA) strains were all susceptible to the glycopeptides and linezolid, but resistant to erythromycin (96%), fusidic acid (91.5%), gentamicin (84%) and clindamycin (73%). Forty one and 39% of the Streptococcus pneumoniae isolates were resistant to penicillin (MIC >0.5 microg/ml) and erythromycin (MIC >1 microg/ml), respectively. S. agalactiae susceptibility was 9% and 10% resistant to clindamycin and erythromycin, respectively. In conclusion, all the Gram-positive isolates tested were susceptible to linezolid. With its oral bioavailability profiles, it obviously holds great promise. Our data should be a useful addition to the literature from the Middle East.

Abstract
OBJECTIVE To investigate the extent, distribution and sequence analysis of bla(CTX-M) genes carried by Escherichia coli isolated from patients admitted to all government hospitals in Kuwait. METHODS Extended-spectrum β-lactamase (ESBL)-producing E. coli isolates were collected from the 8 major hospitals in Kuwait. CTX-M ESBLs were analyzed by PCR and sequenced. Clonality of the positive isolates was determined for genetic relatedness using pulsed-field gel electrophoresis (PFGE) with XbaI digestion of the genomic DNA. RESULTS Of the 136 ESBL-positive isolates, 106 (77.9%) harbored bla(CTX-M) genes. Among these, bla(CTX-M-15) was the most frequent with a prevalence rate of 84.1%, followed by bla(CTX-M-14) (6.8%), bla(CTX-M-14b) (5.7%) and bla(TOHO-1) (3.4%). Ninety-three (87.7%) were isolated from Kuwaiti (35.9%), Egyptian (31.1%) and Indian (20.8%) nationals; the majority of isolates positive for bla(CTX-M-15) were mainly from these 3 nationalities. PFGE analysis did not demonstrate any clustering of positive isolates in any particular hospital. CONCLUSION This study confirms an explosive emergence of CTX-M-15 β-lactamase among E. coli isolates in Kuwait and shows that the strains were clonally heterogeneous with no evidence of inter- or intra-hospital spread. Thus Kuwait may represent an important source of CTX-M-15-positive E. coli.

Abstract
Antibiotic resistance in Escherichia coli is becoming a complex therapeutic problem. Surveillance programs are valuable tools and offer important information on bacterial resistance trends. This study was undertaken to determine the susceptibility of clinically significant isolates of E. coli obtained from patients admitted to 8 Kuwait government hospitals and to examine how this was influenced by the production of CTX-M extended-spectrum beta-lactamases (ESBLs). The susceptibility of 876 consecutive clinically significant strains of E. coli to 13 antibiotics was determined by Etest. ESBL production was assessed by ESBL-Etest method and the presence of CTX-M beta-lactamases was confirmed by PCR technique. Of the 876 isolates, 604 (69%) were highly non-susceptible to ampicillin with MIC(90 )of >256 microg/ml. Resistance to the 3(rd)-generation cephalosporins ranged from 7.5% in the Maternity hospital to 29% in the Ibn Sina hospital; ciprofloxacin resistance rates ranged from 14% and 40%, respectively. Carbapenems and amikacin demonstrated excellent activity. The minimum inhibitory concentrations (MIC(90)) of cefotaxime, ceftazidime, cefepime and ciprofloxacin were >256, 64, >256 and >32 microg/ml, respectively for CTX-M-positive isolates versus 0.5, 1, 025 and 0.125 microg/ml for CTX-M-negative strains. Frequencies of CTX-M-positive isolates within the cefotaxime MIC ranges of 1-2, 3-8, 9-16 and >16 microg/ml were 0, 4, 15 and 81%, respectively. In conclusion, the susceptibility of E. coli to the 3(rd )generation cephalosporins and ciprofloxacin was influenced by the presence of CTX-M ESBL and a high proportion of the CTX-M-producing isolates were in the susceptibility ranges of cefotaxime.

Abstract
We conducted a prospective study to evaluate the prevalence and epidemiology of CDI in Kuwait government hospitals over a 3-year period, January 2003 to December 2005, to determine the ribotypes responsible for CDI and to estimate the prevalence of ribotype 027. We also conducted a case-control study to identify the risk factors in our patient population. A total of 697 stool samples from patients with suspected CDI were obtained and sent to Anaerobe Reference Laboratory, Faculty of Medicine, Kuwait University for Clostridium difficile toxin detection, culture and PCR ribotyping. During the period, 73 (10.5%) out of 697 patients met the case definition of CDI. Of these, 56 (76.7%) were hospital-acquired and 17 (23.3%) were from outpatient clinics. Thus, the prevalence of hospital-acquired CDI amongst patients with diarrhoea was 8% over the study period; the prevalence in 2003, 2004 and 2005 was 9.7%, 7.8% and 7.2%, respectively. Our data showed that 42.9% of the CDI patients were above 60 years, of which >79% were aged 71 years and above. Patients with CDI were more likely than the controls to have been exposed to immunosuppressive drugs and feeding via nasogastric tube. The most common ribotypes isolated during this study were 002, 001, 126 and 140 and they represent 55.1% of all isolates. PCR ribotype 027 was not isolated.

Abstract
INTRODUCTION Empyema occurring after pneumonectomy is a major complication usually diagnosed during the same hospitalization. However, late-onset empyemas are not infrequent and may be difficult to diagnose and manage. PATIENTS AND METHODS From 1995 to 2008, 15 patients were referred to our department for an empyema that occurred between four months and 16years following a pneumonectomy (mean is equal to four years). We more particularly reviewed the mode of occurrence, the possible causes and the management of those late infections. RESULTS Presentation and characteristics were miscellaneous and delay in diagnosis was generally the rule. Two tendencies were emerging according to the delay of occurrence. During the first year following the pneumonectomy, the patients (n=8) had often received an adjuvant treatment (radiation therapy: n=2; radiation and chemotherapy: n=1; chemotherapy: n=2), often presented a bronchial fistula (n=5), and post-management morbidity (two deaths). After the first year, the patients (n=7) were without bronchial fistula, had rarely received an adjuvant therapy (n=1), and were rather suffering multiple associated diseases (n=3), or a bacteremia (n=3), and the treatments were more rapidly efficient. CONCLUSION Empyema is among the first diagnoses to think about in case of fever occurring late after pneumonectomy. Early diagnosis may permit more rapid management and hence, easier and better recovery.

Abstract
OBJECTIVE To report a relatively rare presentation of methicillin-resistant Staphylococcus aureus (MRSA) meningitis in a previously healthy boy in Kuwait. CLINICAL PRESENTATION AND INTERVENTION A 14-year-old boy presented with a 2 weeks' history of headache and fever with increasing severity. He developed photophobia and double vision 2 days prior to his hospital visit and received ceftriaxone for 6 days prior to admission to the hospital. There was no history of head trauma or neurosurgical operation. Lumbar puncture revealed a slightly turbid cerebrospinal fluid with pleocytosis and greatly reduced glucose, elevated protein level and on culture grew MRSA. Staphylococcal chromosome cassette mec (SCCmec) typing revealed that it belonged to SCCmec type III and sequence type 238 (ST238-SCCmec-III). Polymerase chain reaction screening for the presence of Panton-Valentine leukocidin (PVL) genes yielded a negative result; all these findings were consistent with hospital-acquired MRSA. He was treated with intravenous linezolid and rifampicin for 2 weeks, made good response and was discharged home fully recovered and well. CONCLUSION Hospital MRSA should be considered in the differential diagnosis of the causative agents of community-onset meningitis in healthy patients even without predisposing factor.

Abstract
The incidence of Acinetobacter baumannii infection has greatly increased over recent decades with infections occurring more in critically ill hospitalised patients. Hospital outbreaks of multiple antibiotic-resistant strains are posing an increasing threat to public health. Three different outbreaks of multidrug-resistant A. baumannii (MRAB) infections involving 24 patients, aged 16-75 years occurred in the intensive care unit in the course of one year. The isolates were cultured from clinical samples and identified using automated Vitek II ID system and the API 20NE system. Susceptibility testing was done by the E-test method. Molecular typing of the isolates was determined by pulsed-field electrophoresis. Screening of both patients and the environment was carried out. The acquisition time, i.e. the time of admission to time of acquiring infection, ranged from 3 to 31 days. All isolates were multiply resistant (MRAB), including resistance to carbapenems (MRAB-C) in the majority of cases but susceptible to tigecycline, with a minimum inhibitory concentration (MIC(90)) of 2 microg/mL. The overall mortality rate was 16.7%. Time-to-clearance of the MRAB-C was 8.3 days in the first outbreak, when tigecycline was not used, and 2.8 and 3.1 days during the second and third outbreaks, respectively, when tigecycline was used, and all but one patient survived. Environmental screening revealed gross contamination of many surfaces and equipment within the unit. The outbreak strains belonged to two distinct clones (D and E) whereas the 14 environmental strains belonged to three distinct groups (A-C). The outbreak of infections treated with tigecycline was successfully eliminated in conjunction with an aggressive infection control strategy.

Abstract
OBJECTIVES Photodynamic therapy (PDT, the combination of light with a photosensitising drug in the presence of oxygen) inhibits restenosis after angioplasty without stenting. This study assesses the potential of PDT for prevention of in-stent re-stenosis. DESIGN AND METHODS Normal rabbits were given the photosensitising agent 5-aminolaevulinic acid (ALA) 60 mg/kg, 3 h prior to endovascular illumination of the iliac artery (635 nm at 50 J/cm(2)) either immediately before or after deployment of an oversized (3 mm diameter) stent. PDT treated arteries were retrieved 3 or 28 days later and assessed for cell counts and vascular morphometry. Control arteries (stent but no PDT) were examined at 28 days. RESULTS There were no adverse events and all vessels were patent at the end of the study. At 3 days there was almost complete medial cell ablation when light was delivered before stent deployment (17+/-1 cells/hpf), with little effect when illumination followed stent deployment (184+/-17 cells/hpf, p<0.0001). Twenty-eight days after PDT, the neointimal areas were 1.41+/-0.52 mm(2) (stent with no PDT), 1.24+/-0.54 mm(2) (light after stent) and 0.60+/-0.21 mm(2) (light before stent) (p=0.004). CONCLUSIONS PDT before stent deployment caused almost complete medial cell ablation at 3 days with inhibition of in-stent restenosis at 28 days. PDT is worthy of further study as an adjuvant to percutaneous intervention in patients with vascular disease.

Mesenchymal chondrosarcoma is a rare, aggressive, malignant neoplasm, which arises from extraskeletal sites in 30-40 per cent of cases. It is extremely rare in children. We present a novel case of childhood mesenchymal chondsarcoma arising from the vagus nerve in the neck, resulting in paralysis of the right vocal fold. The clinicopathologic features and management of this case are described along with a brief discussion on the aetiology of vocal fold paralysis in this age group. Current literature on extraskeletal presentation of mesenchymal chondrosarcoma is reviewed.
