Extrapulmonary tuberculosis (TB) still presents a diagnostic and therapeutic challenge. Genitourinary TB constitutes about 20% of the extrapulmonary cases in regions where TB is endemic. Tuberculous infection of epididymis and testis is difficult to differentiate clinically from pyogenic infection, tumour or infarction. High-resolution sonography is currently the best readily available technique for imaging the scrotum and its contents, and accurate differentiation is important for proper diagnosis and treatment. The authors are presenting a unique case of chronic epididymo-orchitis with scrotal ulcers.
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 fever, dengue fever, dengue haemorrhagic fever (DHF), or dengue shock syndrome. Annually, 100 million cases of dengue fever and half a million cases of DHF occur worldwide and 2.5 billion people are at risk. At present, dengue is endemic in 112 countries. Early recognition and prompt initiation of appropriate treatment are vital if disease related morbidity and mortality are to be limited. We present an interesting case of dengue fever with headache, skin rash and abnormal behaviour who had a massive intracranial haemorrhage with fatal outcome.
Lupus mastitis is a form of lupus profundus that is seen in patients with systemic lupus erythematosus. It usually presents as a swelling (or swellings) in the breasts, with or without pain. The condition is recurrent and progresses along with the underlying disease, with fat necrosis, calcification, fibrosis, scarring, and breast atrophy. Lupus mastitis is often confused with malignancy and lymphoma and, in our part of the world, with tuberculosis. Confusion is especially likely when it occurs in an unusual clinical setting. In this article, we present a case that presented with unique radiological, pathological, and clinical features. Awareness of the various manifestations of lupus mastitis is essential if unnecessary interventions such as biopsies and surgeries, and their consequences, are to be avoided.
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 usually life threatening with a 50% mortality rate. A strong association with concomitant infection is thought to act as the main trigger of microthromboses in cAPS. Several theories have been proposed to explain these physiopathological features. Some of them suggest the possibility of molecular mimicry between components of infectious microorganisms and natural anticoagulants, which might be involved in the production of cross-reacting antiphospholipid antibodies. We present a case of catastrophic cerebral APS characterised by massive temporal lobe infarction and subsequent haemorrhagic transformation after sudden withdrawal of warfarin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
