Airline travel during the holidays is one big headache. But for some people, “airplane headache” is a truly painful experience. The headache occurs during take-off and landing, is unique to plane travel, and is not associated with other conditions. The pain is severe, with a jabbing or stabbing quality, and located on one side of the head (usually around the eye sockets or forehead).

The paper by Nahit Motavalli Mukaddes and colleagues  provides some important, if small-scale, information when it comes to that still controversial term - optimal outcome - with the diagnosis of autism in mind. Optimal outcome basically refers to a particular 'type' of autism whereby following a definite diagnosis of autism or autism spectrum disorder (ASD), a later re-evaluation of signs and symptoms reveals that diagnostic thresholds are subsequently not reached and/or exceeded a........

The paper by Wenjie Sun and colleagues  (open-access) provides the blogging fodder for today's post and although based on the science of epigenetics, the usual suspect - DNA methylation - gives way to another concept: histone acetylation with autism in mind. Before heading into the paper myself, I'll draw your attention to some other write-ups of the study including a hat-tip to Jeff Craig and his piece on the topic (see here).So histone acetylation...

Birt–Hogg–Dubé syndrome (BHD) is caused by germline mutations in the FLCN gene and characterized by fibrofolliculomas, lung cysts, spontaneous pneumothorax and renal tumours. The stretch hypothesis for pulmonary cyst formation proposes that cysts in BHD arise from defects in cell–cell adhesion, leading to repeated respiration-induced physical stretch-induced stress and, over time, expansion of alveolar spaces particularly in vulnerable regions of lung (Kennedy et al., 20........

"This study does not support the hypothesis that MPH [methylphenidate] increases risk of incident psychotic events. It does indicate an increased risk of psychotic events before the first prescription of MPH, which may be because of an association between psychotic events and the behavioural and attentional symptoms that led to psychiatric assessment and initiation of MPH treatment."The results published by Man and colleagues  (open-access) sit right with me. I say that on the basis........ Read more »

Parkinson's disease (PD) is a progressive neurodegerative disorder estimated to affect 7 to 10 million individual worldwide.The primary mechanism for Parkinson's disease is a reduction in the neurotransmitter dopamine in the midbrain region of the substantia nigra highlighted in red in the figure.PD impairs motor and cognitive functions and leads to significant decline in psychosocial functioning.Drugs for PD can be effective in reversing and slowing the progression of the illness.

The results published by Robert Joseph and colleagues  provide some blogging fodder today, observing that as part of the ELGAN (Extremely Low Gestational Age Newborns) Research Study, gestational age might matter when it comes to offspring risk of autism spectrum disorder (ASD).Gestational age is a measure of how far along a pregnancy is but in the context of the Joseph study refers to premature birth or those "born at least 3 months early." Researchers included data for nearly 1000........ Read more »

I don’t mean to brag, but I’ve got irritable bowel syndrome, says a character of a sitcom.
Irritable bowel syndrome used to be a rare condition, but became a problem of epidemic proportions, until the disease "came out of the closet". Then Internet searches and doctor visits started to dwindle down and less than halved compared to earlier decades.

Follicular lymphoma is a B-cell lymphoma that remains incurable with conventional therapies. Ying et al. (2016) present a new study exploring the biological and genetic features of follicular lymphoma and identifying potential new therapeutic targets. The authors identified recurrent mutations in the mTOR regulator RRAGC, a small G-protein, in approximately 10% of follicular lymphoma cases. Mutations in RRAGC localized to one protein surface area surrounding the GTP/GDP–binding sites. In s........ Read more »

Consider this short blog post an extension of some previous discussions (see here and see here) on a rather peculiar 'association' between urinary tract infections (UTIs) and psychosis. UTIs basically refer to an infection in any part of the urinary system (kidneys, bladder, etc) typically treated with antibiotics. Psychosis is a state that causes a person to perceive or interpret things around them in an atypical way, usually accompanied by delusions or hallucinations. For a while now........ Read more »
