Fibromatosis and/or desmoid tumors which constitute less than 1% of all neoplasms and 3.0% of all soft-tissue tumors are pathologically benign proliferations of the fibroblasts but are locally aggressive with infiltrative type of growth and tendency toward recurrence. Bilateral symmetrical perirenal involvement has been described in many conditions which can be renal, subcapsular, or perirenal in origin. However, bilateral perirenal fibromatosis as an isolated presentation was very uncommon. We report an exceptionally rare case of bilateral perirenal fibromatosis with renal infiltration...

Hepatic endometriosis is a very rare medical condition characterized by the implantation of ectopic endometrial tissue within the hepatic parenchyma. Preoperative diagnosis is difficult via cross-sectional imaging and histopathologic evaluation remains the gold standard for diagnosis. We report a case of hepatic endometrioma in a 44-year-old woman with history of endometriosis. The literature is reviewed, and magnetic resonance imaging findings together with differential diagnosis of hepatic endometriosis are highlighted...

REVIEW
Joshua L Hood
Cells produce extracellular nanovesicles known as exosomes that transport information between tissue microenvironments. Exosomes can engage and regulate the function of various immune cell types facilitating both normal and pathological processes. It follows that exosomes should also associate with lymph nodes containing immune cells. Herein, data derived from investigations that incorporate experiments pertaining to the trafficking of exosomes to lymph nodes is reviewed. Within lymph nodes, direct evidence demonstrates that exosomes associate with dendritic cells, subcapsular sinus macrophages, B lymphocytes and stromal cells...

BACKGROUND: It has been suggested that the higher prevalence of cataract in women is caused by a withdrawal effect of oestrogen at menopause. In vitro studies have demonstrated protection of serum oestradiol (E2) against oxidative stress through upregulation of antioxidant enzymes, including superoxide dismutase (SOD). The purpose of the present study was to investigate E2 levels and SOD erythrocyte activity in patients with age-related cataract. METHODS: The studied subjects consisted of 103 patients with age-related cataract and 22 controls...

A 22-year-old male patient presented in 1988 with active vernal keratoconjunctivitis. He was treated with topical mast cell stabilisers and corticosteroids. Chronic inflammation despite topical treatment necessitated oral immunosuppressants. Active disease came under control with this; however, the patient gradually developed limbal stem cell deficiency. He underwent bilateral pannus resection with amniotic membrane transplantation that resulted in improved ocular surface. In 2007, patient was found to have significant bilateral posterior subcapsular cataracts and underwent bilateral cataract surgery with intraocular lens implantation with good visual outcome...

The spontaneous subcapsular hematoma of the liver is very rare. There are only a few reported cases in the literature.Most reported cases of liver hematoma often occur during pregnancy as part of the hemolysis, elevated liver enzymes, and low platelet count syndrome. The other causes may be due to amylosis, rupture of hepatocellular carcinoma, adenoma, focal nodular hyperplasia, hemorrhagic cyst, or hemopathy. Idiopathic spontaneous subscapular hematoma is a rare and often fatal condition.We report a case of a 43-year-old woman having Steinert disease who died because of a fatal spontaneous liver hemorrhage occurring without any traumatism...

An 18-year-old boy with an obsessive-compulsive disorder of eye rubbing presented with forme fruste keratoconus (KC) and posterior subcapsular cataracts. After evaluation, he underwent phacoemulsification in his left eye with intraocular lens implantation. The aggressive eye rubbing, however, aggravated the rapid progression to established KC, and further acute corneal hydrops within 3 months. Within the next 3 months, the eye rubbing precipitated rhegmatogenous retinal detachments (RDs) in both eyes. Furthermore, after undergoing a combined cataract and RD surgery with belt buckling and silicone oil endotamponade in his right eye, the repeated eye rubbing caused extrusion of the implanted silicone oil into the subconjunctival space and within the corneal stroma...

The 2015 Global Meningococcal Initiative (GMI) meeting discussed the global importance of meningococcal disease (MD) and its continually changing epidemiology. Areas covered: Although recent vaccination programs have been successful in reducing incidence in many countries (e.g. Neisseria meningitidis serogroup [Men]C in Brazil, MenA in the African meningitis belt), new clones have emerged, causing outbreaks (e.g. MenW in South America, MenC in Nigeria and Niger). The importance of herd protection was highlighted, emphasizing the need for high vaccination uptake among those with the highest carriage rates, as was the need for boosters to maintain individual and herd protection following decline of immune response after primary immunization...

Designing modern vaccine adjuvants depends on understanding the cellular and molecular events that connect innate and adaptive immune responses. The synthetic TLR4 agonist glycopyranosyl lipid adjuvant (GLA) formulated in a squalene-in-water emulsion (GLA-SE) augments both cellular and humoral immune responses to vaccine Ags. This adjuvant is currently included in several vaccines undergoing clinical evaluation including those for tuberculosis, leishmaniasis, and influenza. Delineation of the mechanisms of adjuvant activity will enable more informative evaluation of clinical trials...

Page kidney refers to the occurrence of hypertension secondary to renal compression and is usually associated with a subcapsular or perinephric hematoma. It generally occurs weeks to months after the initial injury. We report on a case of Page kidney occurring acutely after Grade IV blunt renal trauma in a pediatric patient with a solitary kidney following a tobogganing accident. The child was initially managed conservatively and discharged after six days bed-rest. He re-presented post-injury Day 12 with recurrent hematuria, anemia, hypertension, and renal failure that required eventual, and successful, surgical exploration...

BACKGROUND: Reliable and reproducible transplantation is essential to the success of a number of particular investigations. Renal subcapsule is the most selected site for islet transplantation mainly owing to its easy access, readiness for retrieval, and possibility of reimplantation. METHODS: Syngeneic, allogeneic, and xenogeneic islets were transplanted into kidney capsules of Balb/C and C57BL/6J mice, and the blood glucose levels of the experimental animals were periodically monitored...

Gastrin is a peptide hormone that is involved in the regulation of sodium balance and blood pressure. Dopamine, which is also involved in the regulation of sodium balance and blood pressure, directly or indirectly interacts with other blood pressure regulating hormones, including gastrin. This study aimed to determine the mechanisms of the interaction between gastrin and dopamine and tested the hypothesis that gastrin produced in the kidney increases renal dopamine production to keep blood pressure within the normal range...

Our group previously purified human and rat aldosterone synthase (CYP11B2 and Cyp11b2, respectively) from their adrenals and verified that it is distinct from steroid 11β-hydroxylase (CYP11B1 or Cyp11b1), the cortisol- or corticosterone-synthesizing enzyme. We now describe their distributions immunohistochemically with specific antibodies. In rats, there is layered functional zonation with the Cyp11b2-positive zona glomerulosa (ZG), Cyp11b1-positive zona fasciculata (ZF), and Cyp11b2/Cyp11b1-negative undifferentiated zone between the ZG and ZF...
