  • S Mansoni ovum is laterally spined, hence diarrhoea is often blood mixed
    Mohammed Naim

    Schistosoma mansoni parasitizes medium sized mesenteric veins and arteries and its ovum is armed with a lateral spine, so intestinal mucosa suffers on account of ova from mesenteric arteries reaching the mucosal capillaries. Spine helps rupture of capillary facilitating release of the ovum and blood into the lumen of the intestine. So diarrhoea in case of S mansoni infestation is often blood mixed, particularly in the ph...

    Loretta S Cheung

    On 24 April 2010 at about 8 pm I was taken to Accident and Emergency Department of Prince of Wales hospital (Sydney) by my daughter because I could not recall what had happened during the afternoon. I could remember events up till meeting friends for lunch at 12 noon, then events from 5 pm. My daughter stated that I "was not myself" and repeated same questions/phrases since I returned home at 4:30 pm,

    I do not h...

  • B12 and neurology
    Santosh V Kondekar

    B12 deficiency has always been a puzzle in pediatric population. Theoretically B12 deficiency is claimed to not occur in children due to reduced need of children and it takes years to develop cobalamine deficiency in children from malnutrition. Although most B12 deficient infants are failing to thrive, the aetiology for B12 deficiency is probably intrauterine and may be maternal B12 deficiency in addition, which explain...

  • Long-haul air travel motion sickness and cerebellar oedema.
    mohammed naim

    The evidence presented by authors (Brian Hurwitz,and Joshua Richardson) is informative. However, it may be added further that Long-haul air travel has been well known to give rise to high altitude motion sickness, cerebellar edema and speech and orientation problems[1]. The young 14-year-old fellow and his father, since, showed no investigative findings confirmatory of viral disease. So it could be that they were more sus...

  • Caption Marks on MRI images.
    Mohammed Naim
    Sir,caption marks which appear missed on MRI images in this case are important for learning of the new and the practicing generations of the pathologists besides of the imaging diagnosticians, and clinicians. For the pathologists MRI images give cut surface views in vivo helpful in final diagnosis on biopsy or autopsy where ever required. Image markings hence may be promoted by reviewers and editors.

  • Massive cerebellar infarctions; where are standing and what are we expecting?
    Osama SM Amin

    We are thankful to Epstein and Naqvi for reporting this case and reminding us of its lesson. However, I would like to address the following:

    The cerebellum is supplied by three arteries; posterior inferior cerebellar arteries (PICA), anterior inferior cerebellar artery AICA) which is usually a single artery, and superior cerebellar arteries (SCA). These vessels and their branches anastomose with each other to f...

  • Catatonia in recent days
    Osama Hammer

    Catatonia is not a diagnosis. Rather, catatonia is a descriptive term for a presentation observed in a wide variety of disorders. Catatonia continues to be recognised in the UK by about 1/3 of psychiatrists surveyed in South West England and Wales. The understanding of the condition may differ. This implies that under diagnosis may lead to suboptimal treatment and fatalities as the differential diagnosis of catatonia in...

  • Evidence of MALTL poorly presented
    Mohammed Naim

    MRI in this case depicted tumor in a location where carcinoma is the most common neoplasm and lymphoma rare. Evidence is hardly of any use for readers unless microscopic evidence accompanied the MRI images. More important it was in view of the documentation that it was not typical lymphoid lesion in biopsy report but a lymphoepithelial mass; so, not necessarily neoplasm nor necessarily lymphoma, hence, awaiting final di...

  • Intra-cranial dural venous sinus thrombosis: what have we learned?
    Osama S.M. Amin

    Dear Editor,

    I read with interest this article about intra-cranial dural venous sinus thrombosis, and many thanks go to the authors for the images.

    Because the article is an "Images in...," I have the following notes:

    The images do not tell which dural sinus (or sinuses) is thrombosed.

    Pointing out to the abnormal areas on the images would be very helpful to the readership.
