Dengue viral infections are one of the most important mosquito borne diseases in the world. The dengue virus is a single stranded RNA virus belonging to the Flaviviridae family. There are four serotypes (DEN 1-4) classified according to biological and immunological criteria. Patients may be asymptomatic or their condition may give rise to undifferentiated(More)
Sheehan's syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some(More)
Actinomycosis is an infectious disease caused by anaerobic gram-positive, non-spore forming bacteria of the genus Actinomyces that affects the oropharynx, digestive tract, and genitalia. Thoracic actinomycosis may affect the respiratory tract and the pleura, even extending to the chest wall. Pulmonary actinomycosis occurs in immunocompetent persons during(More)
Catastrophic antiphospholipid syndrome (APS) is caused by thrombotic vascular occlusions that affect both small and large vessels, producing ischaemia in the affected organs. The "catastrophic" variant of the antiphospholipid syndrome (cAPS) develops over a short period of time. Although patients with cAPS represent <1% of all patients with APS, they are(More)
Peptic ulcer perforation and haemorrhage is not unusual as a complication of peptic ulcer disease. In the older patientspresentation can be dramatic and atypical. The authors are presenting a case of duodenal ulcer perforation and haemorrhage which was misdiagnosed as a gastric malignancy and thus failure to have Helicobacter pylori eradication, recurrence(More)
Chiari in 1891 described a constellation of anomalies at the base of the brain inherited congenitally, the characteristic of which are (1) extension of a tongue of cerebellar tissue posterior to the medulla and cord that extends into the cervical spinal canal; (2) caudal displacement of the medulla and the inferior part of the fourth ventricle into the(More)
Congenital chloride diarrhoea (CCD) is a serious inherited defect of intestinal electrolyte absorption transmitted in an autosomal recessive way. The molecular pathology involves an epithelial Cl(-)/HCO(3)(-) exchanger protein, encoded by the solute carrier family 26 member 3 gene (SLC26A3) and known DRA (down regulated in adenomas) in the distal ileum and(More)
Toxic epidermal necrolysis (TEN) is a rare but life threatening skin disease that is most commonly drug induced. The exact pathogenesis of TEN is still unknown and many drugs, including prednisolone, cyclosporin and intravenous immunoglobulin (IVIG), have been used in an attempt to halt the disease process. The use of IVIG in particular is controversial.(More)
A method for generating the cursive scripts of Arabic-Farsi -Urdu fami ly of languages was developed by Hyder (1). This principle, commonly known as contextual analysis, has now become the universal standard for all input-output devices: e.g. computer terminals, teleprinters, typewri ters, etc. In the present paper the inverse problem is studied and the(More)
