Use of levetiracetam in treating epilepsy associated with other medical conditions

OBJECTIVE: This prospective, open-label study was conducted to evaluate the effectiveness, tolerability, and safety of levetiracetam in patients with epilepsy in whom unfavorable metabolism, complex drug interactions, or direct toxic effects of antiepileptic drugs (AEDs) had caused a worsening of comorbid conditions. METHODS: Study design included the introduction of levetiracetam, discontinuation of other AEDs, and a serial assessment comprising electroencephalograms and blood tests at baseline and 2, 6, and 12 months. Of 21 patients, 16 had partial and five generalized epilepsy. Concomitant pathologies were gastroenterological (six), vascular (four), endocrinological (four), or complex conditions including hematological (four) or dermatological (three) disease. A change of regimen was necessitated by drug-drug interactions in four patients, direct real or potential toxic effects of previous AEDs in 13, and a combination of interactions/toxic effects in four. RESULTS: After 12 months, 12 patients were seizure-free, nine had reductions in seizure frequency of 50-75%, and improvement in concomitant medical conditions was observed. No side effects were reported. CONCLUSION: Levetiracetam appears to be effective, well tolerated, and safe in patients with epilepsy and other medical conditions that are difficult to manage because of drug interactions or AED-related side effects.     

Potential biases in colorectal cancer screening using faecal occult blood test

Background Colorectal cancer (CRC) is one of the most common types of cancer in European countries and associated with a high mortality rate. A 16% relative risk reduction (RRR) of mortality was found in a meta‐analysis based on four randomized controlled trials (RCT) on CRC screening. The aim of this paper was to scrutinize these trials for potential biases and assess their influence on the screening trials. Methods The four RCTs were reviewed based on the principles of ‘Critical Appraisal of the Medical Literature’. Principal investigators of the four RCTs were contacted to clarify uncertainties in their study. Data were collected from The Danish Data Archives. Authors of the Cochrane review were contacted. Results Six biases were identified, of which five favour screening. Three of the biases identified were specific to CRC screening: type of diagnostic method, place of surgery and diagnostic delay. Conclusion The 16% RRR in CRC mortality found in the updated Cochrane review's meta‐analysis is overestimated.     

Ictal haemodynamic changes in a patient affected by “subtle” Epilepsia Partialis Continua

We report on a 64 year-old woman presenting with Epilepsia Partialis Continua (EPC) affecting the left hand since the age of 24 without neurological deficit. Structural MRI showed a region of focal cortical dysplasia (FCD) over the right central gyrus and lesions in the mesial frontal and occipital cortex secondary to perinatal hypoxic injury. Ictal spike haemodynamic mapping using simultaneous EEG-fMRI revealed significant BOLD signal changes prominent in the region of FCD (larger cluster), occipital cortex (global statistical maximum), prefrontal cortex and cerebellum. The cluster over FCD was in good agreement with the result of EEG source analysis.Our findings provide an interesting illustration of the ability of EEG-fMRI to reveal epileptogenic networks confirming the intrinsic epileptogenic properties of dysplastic neurons.     

Development of health‐related quality of life and symptoms in patients with advanced cancer in Greenland

A prospective national cohort study assessed the development of health‐related quality of life (HRQoL) and symptoms in adult patients undergoing treatment and care for advanced cancer in Greenland. HRQol was examined by EORTC QLQ‐C30 version 3.0 questionnaire monthly for 4 months. Changes over time and between‐group comparisons were examined. Of 58 patients included in the study, 47% completed the questionnaire four times. Functioning was generally high, and improved social functioning was observed after 1 and 2 months. The highest symptom score was for fatigue followed by pain and nausea/vomiting. A high score for financial problems remained unchanged during the entire period. Patients with higher income had reduced pain intensity (p = .03) and diarrhoea (p = .05) than patients with income below the poverty line. After 1 month, reduction in pain intensity was observed for Nuuk citizens compared with non‐Nuuk citizens (p = .05). After 2 months, non‐Nuuk citizens reported improved social functioning compared with Nuuk citizens (p = .05). After 3 months, Global Health in Nuuk citizens was improved compared with non‐Nuuk citizens (p = .05). An important clinical finding was that patients’ needs for support are related to social status, and geographical factors should be taken into account when planning palliative care.     

Spontaneous gastric rupture in the newborn: a clinical review of nineteen cases.

The term "spontaneous gastric rupture" is used to describe our cases of neonatal gastric perforation. Nineteen such neonates are reviewed. Current opinions regarding the possible etiology is included in the discussion. Neonatal asphyxia was the most commonly seen predisposing cause in our series (63%). Roentgenograms of the abdomen are most helpful in making a positive diagnosis. Surgical repair is the treatment of choice. All the surviving patients in our series underwent surgical repair. The need for gastrostomy during surgery should be individualized. The mortality was 27% in the cases operated since 1970; a significant improvement as compared to a mortality rate of 62% for the cases operated before 1970.     

Operative treatment and arthroscopic findings in chronic patellar tendinitis

Patellar tendinitis is a well-described clinical entity that usually responds well to conservative treatment. However, a subset of patients continue with symptoms despite exhaustive nonoperative means. The objective of the study was to review the treatment course and operative results of seven patients (eight knees) with chronic patellar tendinitis treated surgically. Five (70%) of these patients were either professional or collegiate athletes. The average age was 30 years (range, 20 to 45 years). Duration of symptoms averaged 1.4 years (range, 3 months to 4 years) before surgical correction. Operative treatment included knee arthroscopy and open repair consisting of excision of degenerated tissue and stimulation of a healing response of the patellar tendon pathology. Operative findings and pathology reports consistently showed marked fibrotendinous degeneration. Follow-up averaged 3.6 years (range, 4 months to 8.5 years). Outcomes were measured subjectively with SF36 results and objectively with Biodex testing (Biodex, Shirley, NY) and return to previous level of competition. Overall, 86% of patients achieved an excellent result and 14% had a fair result. We recommend operative intervention in a patient with chronic patellar tendinitis who does not improve with well-supervised, comprehensive conservative treatment.

Developing best practice for fungal specimen submission - fungal audit of general practice

The objective of this study was to investigate the management of suspected fungal nail infections by general practitioners (GPs) and determine whether guidance is sought when submitting specimens for investigation or treating cases. Questionnaires were sent to all GPs (n = 2420) served by five Health Protection Agency (HPA) collaborating laboratories in the South West of England. A total of 769 GPs responded – topical and oral antifungals were never used by 29% and 16% of GPs respectively. When antifungals were prescribed, topicals were normally given because of the severity of infection (32%); Amorolofine (53%) was the preferred choice. Oral antifungals were most often prescribed after receipt of a laboratory report (77%); Terbinafine was the preferred choice (86%). Seventy percent of GPs would only treat a suspected nail infection with oral antifungals after sending a sample for investigation, yet 27% never waited for a microscopy report before prescribing oral antifungal treatment. GPs routinely send specimens from suspected fungal nail infections for microbiological investigation, yet treatment is often prescribed before a result is received. With clinical signs of fungal infections often non‐specific, GPs should rely on laboratory results before prescribing expensive and lengthy antifungal treatments. Laboratories could further reduce antifungal use by including guidance on microscopy and culture reports.
