Abstract
The effect of standardised, Western acupuncture on hay fever symptoms was investigated in a randomised, controlled, single-blind trial in comparison with “sham” acupuncture. Three general practices, in Oxfordshire (rural), Lincolnshire (semi-rural), and Peterborough (urban), recruited 102 patients aged 16 or over with long-standing, moderate or severe hay fever symptoms that had required continuous therapy for at least one month of the year for three or more consecutive years. The patients were asked to keep a diary to record: the amount of medication used daily; a daily symptom score (using a ten-point scale), from which was derived a weekly remission of symptoms score; and their assessment of the effect of acupuncture on the hay fever symptoms. Symptom scores and use of medication were similar in the two groups. In the four-week period following each patient's first treatment, remission of symptoms was reported by 39.0% in the active treatment group and 45.2% in the sham group; mean weekly symptom scores were 18.4 and 17.6 respectively; and mean units of medication used were 4.1 and 5.0 respectively. Sixteen out of 43 patients in the active treatment group and 14 out of 43 in the sham group felt that the acupuncture had had an excellent or very good effect on their hay fever. The treatments were simple, safe, reproducible and perceived as equally effective. Whether this represented an acupuncture effect, a placebo effect, or natural variation in a fluctuating condition, is not clear.

Abstract
OBJECTIVES While the Restless legs syndrome (RLS) is usually recognized as a chronic condition, it has often been diagnosed among patients with acute neurological illnesses, in which limb discomfort is reported. This study was conducted to determine how many among these, actually have acute-onset RLS, and also to evaluate characteristics of this subgroup of patients with Guillain-Barre syndrome (GBS) and stroke developing acute-onset RLS. METHODS Consecutive patients diagnosed with GBS and eligible stroke patients, admitted to our Neurology services over a 1-year period, were enrolled. They were evaluated for symptoms of RLS based on IRLSSG consensus criteria and the AIIMS RLS Questionnaire for Indian patients (ARQIP). RESULTS Forty adults with GBS and 58 with stroke were included. A total of 10 of the 40 (25%) patients with GBS developed definite acute RLS, which was mostly monophasic. Seven (70%) of these had demyelinating type of GBS, a significant association with acute RLS (P = .024). Six of the 58 stroke patients (10%) developed definite acute-onset, often persistent RLS. Subcortical location showed significant association with increased risk of developing acute RLS (P < .001). All patients diagnosed with acute-onset RLS had an immediate and good response to dopamine agonists. CONCLUSION This is the first study showing that acute-onset RLS is common, affecting nearly 25% of patients with GBS and 10% patients with acute stroke. Recognizing and treating it can majorly contribute toward symptom relief and early improvement in the quality of life for this population.

Abstract
Background: Breast cancer is the most common cancer among women worldwide. Tamoxifen (TAM), a selective estrogen receptor modulator, is widely used in its treatment. TAM is metabolized by cytochrome P450 (CYP450) enzymes, including CYP2D6, CYP3A5 and CYP2C19, whose genetic variations may have clinicopathological importance. However, reports on the association of various P450 polymorphisms with certain cancers are contradictory. Methods: We here investigated whether the prevalence of the four most common polymorphism in the CYP2D6*4 (G1934A), CYP2D6*10 (C188T), CYP3A5*3 and CYP2C19*2 alleles has any link with breast cancer using genomic DNA and polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis. Results: Prevalences of CYP2D6*4, CYP2D6*10 and CYP2C19*2 genotypes were differed significantly (P = 0.01 and P = 0.004) between breast cancer patients and controls. The CYP3A5*3 genotype did not demonstrate statistically significant variation. Conclusion: Polymorphisms in CYP2 appear to be associated with breast cancer risk. Our data taken together with other reports indicates that drug resistance gene polymorphisms might be indicators of response to tamoxifen therapy in breast cancer cases.

Abstract
Waardenburg syndrome (WS) is a rare genetic disorder characterized by varying degrees of hearing loss, pigmentary anomalies, and defects of other neural crest cell-derived structures. The association of WS with renal anomalies has been described in the literature. However, nephrotic syndrome is a very rare association with WS, and only one case has been reported in the literature. We report a case of WS2 associated with biopsy-proven nephrotic syndrome (minimal change disease).

Abstract
Awareness of persistent left superior vena cava (PLSVC), a rare congenital variant is helpful to a clinician to avoid the unnecessary complications. We report a case of PLSVC in a patient with chronic kidney disease which was identified following a difficult catheterization into the right internal jugular vein (IJV). The catheterization was attempted through the left IJV and the position of which could not be confirmed with check radiograph and two-dimensional echo. PLSVC was suspected in the computed tomography angiography and was confirmed following digital subtraction angiography.

Abstract
BackgroundPrevious studies have reported depressive symptoms in patients with persistent delusional disorder (PDD). Patients with PDD and depression may need antidepressants for treatment.AimThe aim of the study was to compare the sociodemographic profile, clinical presentation and treatment response in patients with PDD with and without comorbid depressive symptoms.MethodsWe conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455). We divided the patients into PDD + depression (n = 187) and PDD only (n = 268) for analysis.ResultsOf the 187 patients with PDD + D, only eighteen (3.9%) were diagnosed with syndromal depression. There were no significant differences in sociodemographic profile including sex, marital and socioeconomic status (all P > 0.05). PDD + D group had a significantly younger age at onset ([PDD + D: 30.6 9.2 years vs. PDD: 33.5 11.1 years]; t = 2.9, P < 0.05). There was no significant difference between the clinical presentation including mode of onset, the main theme of their delusion and secondary delusions (all P > 0.3). However, comorbid substance dependence was significantly higher in patients with PDD only. (χ2 = 5.3, P = 0.02). In terms of treatment, response to antipsychotics was also comparable ([> 75% response: PDD + D = 77/142 vs. PDD = 106/179); χ2 = 1.9, P = 0.3). There was a significant difference between the two groups in terms of antidepressant treatment ([PDD + D = 32/187; 17% vs PDD: 17/268; 6%), χ2 = 12.9, P = 0.001).DiscussionPatients with PDD + D had significantly earlier onset of illness. These patients may require antidepressants for treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
This paper covers the design aspects of a new multi-channel electrode for the acquisition of surface electromyography signals from a selected muscle. The new multi-channel electrode has 11 pins where the monopolar signals produced will be configured in a software either as Linear array or Laplacian configuration. The design specification of the pre-amplifier ideally was to have a voltage gain of 500 with bandpass filtering of 5 Hz-1 kHz. The final design of the pre-amplifier circuit using an INA 118 instrumentation amplifier was built and tested to give values for voltage gain of 484 with bandpass filtering of 6.8 Hz-1.02 kHz. The software configuration that gives clearer and more defined signals in terms of motor unit action potentials for future signal processing is the Laplacian rather than Linear array.

Abstract
Statin plays a major role in the primary and secondary prevention of cardiovascular disease (CVD). Inconsistent findings in the studies have been observed toward the risk of intracerebral hemorrhage (ICH) using higher dose of statin. To examine this issue, we performed a meta-analysis of randomized controlled trials (RCTs) to assess the association between higher dose of various statins and risk of ICH among patients with CVD. Literature was searched for studies published before June 10, 2015, using electronic database 'PubMed', 'EMBASE', and 'Google Scholar' as well as from many trial databases. The following search terms were used: 'Statin therapy' AND 'Cardiovascular Disease', AND 'Dose' AND 'Intracerebral hemorrhage', AND 'Randomized Controlled Trials' AND 'High Dose Statin'. High dose of statins was defined as atorvastatin 80 mg, simvastatin 80 mg, pravastatin 40 mg, rosuvastatin 20 mg per day. Fixed-effect model was used to estimate the risk ratio (RR) and 95% confidence interval (CI) if heterogeneity was <50%; otherwise, random-effect model was used. Begg's funnel plot was used to assess the publication bias. Seven RCTs involving 31,099 subjects receiving high-dose statin and 31,105 subjects receiving placebo were analyzed in our meta-analysis. A significant risk of ICH was observed in subjects with higher dose of statin (RR = 1.53; 95% CI: 1.16-2.01; P = 0.002). There was no difference in all-cause mortality between the two groups (RR = 0.95; 95% CI: 0.86-1.06; P = 0.36). No publication bias was observed through Begg's funnel plot. Higher dose of statins was found to be associated with the risk of ICH. Future studies are needed to confirm these findings.
