The neurotransmitter histamine has been suggested to be involved in cognitive functioning. Generally, studies in animals have shown a decrease in performance after decreasing histamine neurotransmission and improved performance after increasing histamine neurotransmission. It is unclear, however, what role histamine pl…

Amyotrophic lateral sclerosis/motor neuron disease and other related disorders are fatal progressive neurodegenerative conditions that have a substantial impact on quality of life (QoL). This systematic review examines the different methods and instruments used to assess QoL in this condition from which recommendations…

The condition of persistently high plasma CK levels is frequently encountered in asymptomatic patients with normal neurological examination. This condition may be the unique manifestation of several neuromuscular disorders, whose diagnosis is now possible using new diagnostic techniques. However, even if these patients…

BACKGROUND: Understanding of data-reporting methods is imperative for correct interpretation of the medical literature as well as for proper performance of future clinical research. Recent developments in biostatistics have greatly changed the types of statistical analyses used and the minimum quality standards that mu…

CASE REPORTS: The authors report their experience about three children (two girls, one boy; average age 1.6 years) with a spontaneous regression of optic gliomas.

Breast ductal carcinoma in situ (DCIS) is a preinvasive form of breast cancer. It typically presents as microcalcifications which are picked up on screening mammogram. We report an atypical case of breast DCIS presenting with recurrent non-puerperal mastitis with a normal mammogram and perform a literature review.

Cases of primary colorectal adenocarcinoma metastasized to the palatine tonsil are extremely rare. To the best of our knowledge, only 10 cases have thus far been previously documented in the English literature. A 37-year-old Chinese woman presented with a right palatine tonsil swelling and odynophagia 5 months after a…

Desmoplastic infantile gangliogliomas (DIG) are intracranial tumors described in 1987 as benign lesions of infancy. A literature review and the clinical course of 3 patients reported herein suggest that the initial description should be amended. Nearly 23% of DIG cases occur in children older than 24 months. Approximat…

Not only in newborns with Down syndrome, but newborns without phenotypic features of Down syndrome also develop transient myeloproliferative disorder (TMD). In these cases, trisomy 21 and related chromosomal abnormalities are either constitutionally mosaic or limited to blood cells. Risk factors for early death of thes…

Currently systematic reviews focus on diagnosis or effectiveness of treatment. It is the understanding of disease aetiology that underpins medical education, practice and research. Whether an association meets causal criteria is usually assessed qualitatively. However, this can also be examined through evidence synthes…

OBJECTIVE: Systematic reviews and meta-analyses are increasingly frequently used in the evaluation of medical treatments. This review explains the principles of the methodology, significance and limitations of systematic reviews. METHOD: Short review article. RESULTS: In contrast to conventional reviews, systematic r…

Although focus groups gather early-stage input effectively, our initial literature review found few focus group studies conducted with autistic adolescents (ages 12-19), despite the potential for focus groups to provide a safe, peer-based setting that encourages autistic adolescent engagement in research. Scoping revie…

CONTEXT: Barriers to the use of systematic reviews by policymakers may be overcome by resources that adapt and present the findings in formats more directly tailored to their needs. We performed a systematic scoping review to identify such knowledge-translation resources and evaluations of them. METHODS: Resources wer…
