Given the wealth of data in the literature on schizophrenia endophenotypes, it is useful to have one source to reference their frequency data. We reviewed the literature on disease-liability associated variants in structural and functional magnetic resonance images (MRI), sensory processing measures, neuromotor abilities, neuropsychological measures, and physical characteristics in ...

Exposure to manganese dusts and fumes may cause a clinical neurological syndrome called manganism. Welders are frequently exposed to manganese-containing fumes generated by electric arcs and thermal torches. This paper reviews studies on the association between exposure to such welding fumes and neurological disease. Using the IRSST expert panel criteria, ...

Perinatal corticosteroids are like a double-edged sword. On the one hand, they reduce risk for major morbidity and even mortality; on the other hand, they modify growth and development of body systems, with short- and long-term consequences. The relationship between corticosteroids and neurodevelopmental outcome has been extensively studied in randomized ...

Ischemic stroke is associated with leucocyte activation. Activated leucocytes release elastase, an enzyme that can degrade fibrinogen. Fibrinogen elastase degradation products (FgEDP) may serve as a specific marker of elastase proteolytic activity. In a case-control study of 111 ischemic stroke patients and 119 controls, significantly higher FgEDP levels were observed ...

Patients with Semantic Dementia (SD), in addition to their central semantic disorder, tend to show obsessive behaviours. Some SD cases take up jigsaw puzzles post-onset, and continue doing these, sometimes for many hours per day, after other abilities and interests are lost. The current study demonstrates that skill at jigsaws ...

Thyrotoxicosis affects 0.2% of pregnant women and antithyroid drugs are the treatment of choice during pregnancy. Several case reports have suggested a relationship between the prenatal use of methimazole (MMI) and choanal atresia in the offspring. However, two epidemiological studies did not find an increased teratogenic risk for MMI. This ...

Interleukin-6 (IL-6) is a potential mediator of systemic effects of Chronic Obstructive Pulmonary Disease (COPD). In the present case-control study we investigated the association of promoter polymorphisms of this gene and COPD in a cohort of 191 patients, smokers without COPD (n=75) and a healthy control population (n=296). Besides spirometry, ...

Some writers hold the view that the combination of Ginkgo biloba with anticoagulant or antiplatelet drugs represents a serious health risk. Such concerns are largely based on the assumption that Ginkgo has clinically relevant antiplatelet activity, as well as accounts of bleeding episodes associated with Ginkgo consumption. To investigate whether ...

AIM: To briefly review and discuss the literature on vitrectomy for diabetic macular oedema. METHODS: Literature review. RESULTS: There is a copious literature on the subject of vitrectomy for diabetic macular oedema (DMO). The most commonly hypothesised mechanism for the potential benefit of vitrectomy is relief of vitreomacular traction; however, ...

1. The aim of the present study was to examine the relationship between CYP2D6 polymorphisms and the risk of antipsychotic (AP)-induced extrapyramidal symptoms (EPS) in patients receiving AP treatment. The allele status for CYP2D6*3, CYP2D6*4, CYP2D6*5 and CYP2D6*6 was determined in 267 patients receiving AP therapy. Seventy-nine cases presenting with ...

We report on two cases who presented with involuntary facial grimacing and frowning. Blepharospasm has never been documented in one, and the other case showed difficulty in lid opening only in the early phase of the disease. Botulinum toxin was effective for both. This is a hitherto unreported presentation of ...

The role of extracorporeal membrane oxygenation (ECMO) has not been formally validated for patients with adult respiratory distress syndrome. In anticipation of publication of the conventional ventilation versus ECMO in severe adult respiratory failure (CESAR) trial, the role of ECMO in this setting was reviewed. An electronic search for studies ...

Studies of causal links between alcohol and aggression are often handicapped by threats to internal and external validity. Case-control methods employ an event-level analysis that can reduce some of these validity threats by the use of within-subject controls. This study used a case-control approach, asking 39 male inmates in a ...

Status epilepticus still remains a formidable adversary to neurointensivists. Although the majority of cases admitted to the Neuro-ICU are easily controlled with one or two antiepileptic drug defense lines, several cases become refractory and end up receiving general anesthetics for days or weeks with significant morbidity. Treatment algorithms have been ...

Although many medical journals routinely shun publication of case reports, these communications still can play a major educational role. Unexpected presentations, heretofore unreported adverse events and new associations may be illuminated. Although not as rigorous as placebo-controlled, double-blind studies, case reports do have a high degree of sensitivity for detecting ...

Management of orthopaedic injuries in polytrauma cases continues to challenge the orthopaedic traumatologist. Mass disasters compound this challenge further due to delayed referral. Recently there has been increasing evidence showing that damage control surgery has advantages that are absent in the early total care modality. We studied the damage control ...

In case-control studies the frequency of the exposure of interest is compared between a group of diseased subjects and a group of controls to determine whether an association exists between disease and exposure. Case-control studies are useful, but can be subject to several sources of bias if poorly conducted. Selection ...

PURPOSE: Contradictory results were published from two studies in the late 1990s about the effects of long half-life benzodiazepine use on the risk of motor vehicle crashes (MVCs) in the elderly. The use of different study designs could explain the differences observed in these studies. METHODS: The results of an ...
