In a factorial randomized trial conducted in Sri Lanka, de Silva and colleagues evaluate the safety and efficacy of pretreatments intended to reduce the risk of serious reactions to antivenom following snakebite.
BackgroundInternal jugular vein thrombosis is a rare vascular event with a potentially fatal outcome. Of the known etiologies, internal malignancies, either known or occult, are well described. Even though malignancies are known to present with internal jugular vein thrombosis, it rarely occurs due to prostate carcinoma. Many cases of jugular vein and superior vena cava thrombosis secondary to malignancies are due to metastatic compression of veins. Recurrent and unusual vascular thrombosis due to hypercoagulability associated with malignancies is also known as Trousseau’s syndrome. Here we report a rare case of a patient with internal jugular vein thrombosis as a presenting feature of metastatic prostate carcinoma, which is a case of Trousseau’s syndrome.Case presentationA 75-year-old Sri Lankan man with hypertension, hyperlipidemia, and past history of spontaneous intracranial hemorrhage presented with a short history of painless swelling in his left supraclavicular fossa. An examination revealed the swelling was due to a thickened left external jugular vein. A duplex ultrasound scan revealed left-sided internal jugular, external jugular, and brachiocephalic venous thrombosis. Surveillance into underlying malignancies showed an irregular, hard prostate gland suspicious of prostate carcinoma, which was proven with histology, and biochemically. A computed tomography scan found extensive vertebral, pelvic bone, intra-abdominal lymph node metastasis, and a single right-sided lower lung metastatic lesion, with no direct involvement of the jugular vein.ConclusionsSpontaneous thrombosis of the internal jugular vein due to Trousseau’s syndrome is rare and unusual. Clinicians should promptly investigate for malignancies as it can be the first presentation of underlying occult malignancies. Although prostate carcinomas are rare to present with internal jugular vein thrombosis, this case illustrates the importance of having a high degree of suspicion in the appropriate clinical setting.
Background
Dengue haemorrhagic fever is a severe form of acute dengue infection characterized by leakage of plasma through capillaries into body spaces resulting in circulatory insufficiency leading to shock. Despite varying degrees of liver involvement occurring in acute dengue infection, intrahepatic cholestasis is very rare in the literature with only two cases reported so far. We report a challenging case of a middle-aged woman with DHF complicated by acute liver failure, coagulopathy, acute renal failure and prolonged intrahepatic cholestasis. She was successfully managed in the intensive care unit with supportive therapy, Cytosorb® and therapeutic plasma exchange.
Case presentation
A 54-year-old Sri Lankan obese woman with multiple comorbidities presented with fever, headache, vomiting and generalized malaise for 3 days and was diagnosed with dengue haemorrhagic fever. Despite the standard dengue management, she clinically deteriorated due to development of complications such as, acute liver injury, intrahepatic cholestasis and acute renal injury. Acute liver failure was evidenced by transaminitis, lactic acidosis, coagulopathy with pervaginal bleeding and severe encephalopathy necessitating elective intubation and mechanical ventilation. She was immediately transferred to intensive care facilities where she underwent supportive management for liver failure, continuous renal replacement therapy coupled with cytosorb and therapeutic plasma exchange with which she made a remarkable recovery.
Conclusion
Acute liver failure with a prolonged phase of intrahepatic cholestasis is a very rare complication of acute dengue illness which is sparsely documented in medical literature so far. This patient was managed successfully with supportive therapy, aided by cytoSorb hemo-adsorption and therapeutic plasma exchange.
Bronchiectasis is a disabling respiratory disease which results in permanent distortion and dilatation of the affected bronchi. It is a chronic obstructive lung disease with clinical manifestations of chronic cough, sputum production, and recurrent chest infections. It has several aetiologies which include infections, primary immunodeficiency, recurrent aspiration, inhaled foreign body, cystic fibrosis and primary ciliary dyskinesia. Yellow nail syndrome (YNS) is a very rare disease with a clinical triad of nail changes, respiratory manifestations and lymphoedema. Diagnosis can be made in the presence of two of these symptoms. We present a case of a young woman with cystic bronchiectasis and maxillary sinusitis, later diagnosed with yellow nail syndrome. A 22-year-old woman diagnosed with cystic bronchiectasis for 3 years presented with an infective exacerbation. She was noted to have characteristic nail changes involving hands and feet which raised suspicion of YNS. It should be considered in a patient with bronchiectasis and characteristic nail changes, even in the absence of lymphoedema. Therefore, a high degree of clinical suspicion and exclusion of other underlying causes are necessary to arrive at a timely diagnosis.
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.
