Efficacy of botulinum toxin injection before pneumatic dilatation in patients with idiopathic achalasia

Graded pneumatic dilatation (PD) is an appropriate long-term therapy and botulinum toxin injection (BT) is a relatively short-term therapy in idiopathic achalasia. Their combination has not been previously scrutinized. This study aimed to evaluate the role of BT in enhancing the efficacy of PD with 30 mm balloons. Patients who underwent PD with 30 mm balloons after botulinum toxin injections and a group of age- and sex-matched controls who were treated only with PD were enrolled in the study. Symptom scores were taken before, 1 month after and then every 3 months after PD. There were no significant differences between the two groups in gender, duration or severity of symptoms. One of the 12 patients in the case group relapsed 30 months after PD but the others were in remission for an average of 25.6 months. In the control group, all the patients relapsed after a mean of 12.6 months and needed a 35-mm PD. The cumulative remission rate was significantly higher in the case group compared with the control group (P < 0.01). The mean symptom score decreased by 76% in the case group (P < 0.001) and 53% in the controls (P < 0.01) at the end of the first month. Neither age, sex, nor duration or severity of symptoms were predictive of patients' responses to treatment. It seems that BT may be a meaningful enhancing factor in long-term efficacy of PD. PD with a 30 mm balloon after a BT session may resolve the need for the future higher grade PD.     

Identification of Aeromonas strains to the genospecies level in the clinical laboratory.

One hundred thirty-three strains of Aeromonas (human, n = 102; animal, n = 16; environmental, n = 15) previously identified to the DNA group level by molecular methods were biochemically analyzed for 58 properties. On the basis of the use of between 9 and 16 selected tests, 132 of the 133 strains (99%) could be assigned to their correct hybridization group using this biochemical scheme. The results suggest a feasible approach for identifying aeromonads to genospecies level under appropriate conditions.     

Gait speed is more challenging than cognitive load on the stride-to-stride variability in individuals with anterior cruciate ligament deficiency

Background

Several investigations have studied gait variability of individuals with anterior cruciate ligament (ACL) deficiency; however, the effect of dual-tasking on the gait variability of these individuals remained unclear. The aim of the present study was to determine the effect of gait speed and dual-tasking on knee flexion–extension variability in subjects with and without ACL deficiency.

Relationship between female sexual difficulties and mental health in patients referred to two public and private settings in Tehran, Iran

IntroductionSexual difficulty has various effects on patients suffering from this condition that can impact on interpersonal and marital relationships. Sexual function may be adversely affected by stress of any kind and emotional disorders. There have been limited studies focusing on the mental health of those suffering from this problem.AimTo determine the relationship between sexual difficulties and mental health in female patients seeking help in psychiatric clinics.MethodsThe study was based on the case–control design methodology in which the case group consisted of 165 outpatients of two psychiatric clinics, who were diagnosed with different mental disorders such as depression, anxiety, phobia, aggression, and somatic complaints (33 subjects for each type of disorder). The 33 subjects in the control group were chosen among the patients’ relatives and visitors who had no history of either seeking psychiatric help or taking psychiatric drugs. The subjects of both case and control groups were selected based on a convenience sampling method. Moreover, the data were collected based on two techniques of “interview” and “questionnaire;” the latter was of three different subcategories, each dealt with demographic characteristics, sexual difficulties, and a Symptom Check-List-90-Revised.Main Outcome MeasureAssessing female sexual difficulties associated with mental health and differences between women with and without psychiatric problems.ResultsThe obtained results indicated that there was a significant difference between the prevalence of sexual difficulties (e.g., sexual desire and orgasm disorders) in the case group and that of the control group. It was also revealed that there was a significant difference between the depressed, aggressive, as well as those with somatic complaints, and their control group counterparts.ConclusionsIn Iran, sexual difficulties seem to be more frequent in those seeking psychiatric help in clinics than in those within the normal population.

Safety of elective percutaneous peripheral revascularization in outpatients: A 10-year single-center experience

PurposeTo evaluate the safety and feasibility of peripheral percutaneous endovascular procedures in a large group of outpatients with peripheral arterial disease (PAD).Materials and methodsWe retrospectively evaluated all consecutive patients who underwent peripheral transluminal angioplasty (PTA) for PAD of the lower extremities as “Out-Patient Admission Protocol” (OPAP) from January 2005 until December 2015. A total of 498 consecutive patients (305 men and 193 women) with mean age of 66 ± 10 (SD) years (range: 37–90 years) were evaluated. By protocol, patients were expected to be discharged 6 hours after the procedure. Clinical profile, procedure details and technical success were reviewed. Complications, conversion rate, readmission rate and long-term follow-up were evaluated.ResultsNinety one percent of patients (454/498) suffered from claudication. Unilateral femoral access was performed in 75.4% (493/654) of procedures with a 6-French sheath in 80.7% (528/654) of procedures. Balloon PTA alone was performed in 17.3% (148/857) and stent placement in 82.7% (709/857) of treated segments. Technical success of lesion treatment was 98.2% (857/873). Closure devices were used in 55.4% (362/654) of procedures. Conversion and readmission rates were 1.8% (12/654) and 0.6% (4/654), respectively. Long-term follow-up was obtained in 386 target lesions, 5-year restenosis of lesion was 20.5% (79/386).ConclusionAs designed, the OPAP was feasible, safe and effective with very low conversion and complications rates. These results strongly support a larger use of such approaches as routine practice.     

The impact of gross anatomy laboratory on first year medical students’ interest in a surgical career

This study sought to determine the impact of gross anatomy laboratory (GA) on first year medical students’ (M1) interest in a surgical career. Secondary objectives included identifying other influences in M1s’ career decision making. This prospective study included surveys before and after GA. All M1s enrolled in GA were invited to participate. Sixty students completed both the pre‐ and post‐test surveys. A 5‐point Likert‐type scale surveyed participants’ interests, specific personality traits, experience during the course of GA, and likelihood of pursuing a surgical career. Statistical analysis included Wilcoxon Signed Rank Test and (Polychotomous) Ordinal Logistic Regression Model. Students’ desire to work with their hands increased (50 vs. 33.3%) and enjoyment working with instruments and tools similarly increased (50 vs. 41.7%). Likelihood of pursuing a surgical career after gross anatomy increased in 31.7% of students, decreased in 16.7%, and was unchanged in 51.7%. Over 75% of students with a prior interest in surgery and 21% of those who previously felt neutral agreed that they were likely to pursue a career in surgery at the conclusion of the laboratory. Students with a surgeon family member were 0.1976 times as likely to exhibit a positive change in interest (P values 0.024). Gross anatomy may influence up to a third of the class to consider a surgical career, especially those with a prior interest in surgery and those previously feeling ambivalent. Students with a surgeon family member became less likely to enter a surgical career after gross anatomy. Clin. Anat. 29:691–695, 2016. © 2016 Wiley Periodicals, Inc.     

Coeliac disease in Iranian type I diabetic patients

BACKGROUND: The association between coeliac disease and type I diabetes mellitus has been evaluated in some previous studies, but its prevalence in Iranian diabetic patients remains unknown. AIM: To evaluate the prevalence of coeliac disease in patients with type I diabetes mellitus in Iran. PATIENTS: A total of 250 consecutive patients (102 male and 148 female) with type I diabetes mellitus. METHODS: Total serum immunoglobulin A level and immunoglobulin A endomysial antibody was measured for all patients. Endoscopy and biopsy of the duodenum were performed for immunoglobulin A endomysial antibody-positive patients and pathologic evaluation was done according to modified Marsh classification. RESULT: The mean age of the patients was 18.7 years (range: 2-55 years). Total serum immunoglobulin A was in the normal range for all patients. Immunoglobulin A endomysial antibody was positive in six (2.4%) patients (all of them were females; P = 0.04). Duodenal biopsy samples revealed grade I in two patients, grade II in three patients and grade IIIb in one patient (modified Marsh classification). Patients with coeliac disease and diabetes mellitus were older than patients with diabetes mellitus alone (mean age: 29.5 years versus 18.4 years; P < 0.001). There was a trend for longer duration of diabetes mellitus in coeliac patients than in patients without it (mean age: 17.3 years versus 12.5 years; P = 0.16). CONCLUSION: The prevalence of coeliac disease in Iranian patients with type I diabetes mellitus is relatively high (2.4%). Since almost half of the patients with coeliac disease are asymptomatic, all patients with type I diabetes mellitus should be screened for coeliac disease regardless of the presence of symptoms, at diagnosis of diabetes mellitus and with regular intervals in the follow up.     

Coeliac disease in Middle Eastern countries: a challenge for the evolutionary history of this complex disorder?

About 10,000 years ago domestication and farming of wheat and other cereals developed in the 'Fertile Crescent', an area including modern Turkey, Iraq and Iran. Agriculture then slowly spread from Middle East to Europe. Coeliac disease is the permanent intolerance to dietary gluten, the major protein component of wheat. It has been until relatively recently hypothesised that wheat consumption exerted a negative selective pressure on genes predisposing to coeliac disease, eventually leading to higher coeliac disease frequency in Northeastern Europe because of lack of exposure to cereals. This theory is at variance with recent studies showing that coeliac disease is as common in Middle Eastern countries as in Europe. High prevalence of coeliac disease has been found in Iran, in both the general population and at-risk groups, e.g. patients with irritable bowel syndrome or type 1 diabetes. Clinical manifestations of coeliac disease vary markedly with the age of the patient, the duration and the extent of disease. Clinical studies showed that presentation with non-specific symptoms or no symptoms is as common in the Middle East as in Europe. Wheat represented a major component of the Iranian diet for many centuries and it may be argued that the continuous and high level of exposure to wheat proteins has induced some degree of immune tolerance, leading to milder symptoms that may be misdiagnosed as irritable bowel syndrome or unexplained gastrointestinal disorders. The gluten-free diet represents a real challenge to both patients and clinicians in this area. This is particularly difficult in the absence of any supply for gluten-free diet in Middle Eastern countries.
