H1-antihistamines exacerbate high-fat diet-induced hepatic steatosis in wild-type but not in apolipoprotein E knockout mice.

Hide Abstract
We examined the effects of two over-the-counter H1-antihistamines on the progression of fatty liver disease in male C57Bl/6 wild-type and apolipoprotein E (ApoE)-/- mice. Mice were fed a high-fat diet (HFD) for 3 mo, together with administration of either cetirizine (4 mg/kg body wt) or fexofenadine (40 mg/kg body wt) in drinking water. Antihistamine treatments increased body weight gain, gonadal fat deposition, liver weight, and hepatic steatosis in wild-type mice but not in ApoE-/- mice. Lobular inflammation, acute inflammation, and necrosis were not affected by H1-antihistamines in either genotype. Serum biomarkers of liver injury tended to increase in antihistamine-treated wild-type mice. Serum level of glucose was increased by fexofenadine, whereas lipase was increased by cetirizine. H1-antihistamines reduced the mRNA expression of ApoE and carbohydrate response element-binding protein in wild-type mice, without altering the mRNA expression of sterol regulatory element-binding protein 1c, fatty acid synthase, or ApoB100, in either genotype. Fexofenadine increased both triglycerides and cholesterol ester, whereas cetirizine increased only cholesterol ester in liver, with a concomitant decrease in serum triglycerides by both antihistamines in wild-type mice. Antihistamines increased hepatic levels of conjugated bile acids in wild-type mice, with the effect being significant in fexofenadine-treated animals. The increase was associated with changes in the expression of organic anion transport polypeptide 1b2 and bile salt export pump. These results suggest that H1-antihistamines increase the progression of fatty liver disease in wild-type mice, and there seems to be an association between the severity of disease, presence of ApoE, and increase in hepatic bile acid levels.

Role of chest X-ray in citing central venous catheter tip: A few case reports with a brief review of the literature.

Hide Abstract
Central venous catheter (CVC) insertions are increasingly performed in surgical patients and intensive therapy. A simple and invasive procedure performed under strict sterile precautions with complications ranging from arrhythmias; infections; and life-threatening complications such as pericardial tamponade, cardiac perforation and even death. A post-procedure chest X-ray (CXR), though does not accurately assess the tip of the catheter in relation to the superior vena cava (SVC) and right atrium (RA), can detect malpositions, safety of catheter tip, pneumothorax and kinking. We would like to share some of the malpositions we encountered in our centre, their management and a brief review of the literature on optimal catheter tip location.

Progressive nodular histiocytosis with normal karyotypic analysis.

Hide Abstract
Non-Langerhans cell histiocytoses (NLH) comprise a spectrum of diseases that includes sinus histiocytosis with massive lymphadenopathy, hemophagocytic lymphohistiocytosis, xanthogranuloma, and reticulohistiocytoma. Progressive nodular histiocytosis (PNH) is a rare NLH that microscopically mimics juvenile xanthogranuloma but presents with disseminated persistent and progressive papulonodules in adults. Herein, we describe a case of PNH presenting as diffuse, progressively enlarging papules, nodules, and pedunculated tumors in a 38-year-old male. The diagnosis is supported microscopically by the morphologic and immunohistochemical findings. Whereas conventional cytogenetic analysis of Langerhans cell histiocytosis and juvenile xanthogranuloma has previously been described, there are no reports of the karyotype of PNH. In our patient, conventional cytogenetic analysis of the tumor revealed a normal karyotype. Although these results may represent the overgrowth of normal stromal cells rather than lesional cells, we believe this to be an important finding, indicating karyotypic analysis will not allow for distinction between PCH and other NLH or Langerhans cell histiocytoses.

Nonconvulsive status epilepticus: An unusual cause of postoperative unresponsiveness following general anaesthesia.
Indian J Anaesth

Hide Abstract
Any altered behaviour or sensorium following general anaesthesia is of concern to the anaesthesiologist, as it could be attributed to the anaesthetic itself or to a hypoxic insult, both of which can have medicolegal implications. It is important to be aware of a relatively unfamiliar entity known as nonconvulsive status epilepticus in this context. We report two cases to highlight this condition.

Low cost continuous femoral nerve block for relief of acute severe cancer related pain due to pathological fracture femur.
Indian J Palliat Care
PUBLISHED: 10-04-2010
Show Abstract
Hide Abstract
Pathological fractures in cancer patient cause severe pain that is difficult to control pharmacologically. Even with good pain relief at rest, breakthrough and incident pain can be unmanageable. Continuous regional nerve blocks have a definite role in controlling such intractable pain. We describe two such cases where severe pain was adequately relieved in the acute phase. Continuous femoral nerve block was used as an efficient, cheap and safe method of pain relief for two of our patients with pathological fracture femur. This method was proved to be quite efficient in decreasing the fracture-related pain and improving the level of well being.

Greater interobserver agreement by endoscopic mucosal resection than biopsy samples in Barretts dysplasia.
Clin. Gastroenterol. Hepatol.
PUBLISHED: 01-25-2010
Show Abstract
Hide Abstract
Endoscopic mucosal resection (EMR) is an important diagnostic, staging, and therapeutic tool for patients with Barretts esophagus (BE)-associated neoplasia. We analyzed the histopathologic characteristics of specimens collected during EMR compared with biopsy specimens from patients with BE and assessed interobserver variability in pathologists assessment of EMR and biopsy specimens.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
