Supratentorial CAPNON associated with WHO grade II meningioma: A case report

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare benign tumor of uncertain etiology, arising in the craniospinal axis. CAPNON typically arises in isolation, with only two prior reports of a concurrent second neoplasm. Here, we report the case of a male 17‐year‐old who presented with new‐onset seizures. MRIs revealed a 2 cm extra‐axial solid‐cystic mass, arising at the left temporo‐occipital junction and abutting the dura with marked surrounding parenchymal vasogenic edema. The solid components demonstrated dense calcification and avid enhancement. Gross total surgical resection was performed. Histopathological examination revealed central regions showing characteristic features of CAPNON. Toward the periphery, the CAPNON was intimately associated with and sharply demarcated from a meningioma, which showed up to five mitoses per 10 high‐power fields and had invasion into the adjacent brain parenchyma, warranting a WHO grade II designation. This is the first report of CAPNON arising in association with a meningioma. The coexistence of these two tumors raises the possibility of a reactive/dysplastic etiology for CAPNON.     

Children with untreated coeliac disease have sub-clinical cardiac dysfunction: a longitudinal observational analysis

Introduction: We assessed cardiac function (CF) in celiac disease (CD) patients and the effect of gluten-free diet (GFD) on CF.

Methods: Prospective evaluation of CF using conventional and tissue doppler echocardiography in 50 CD patients (age 4.2?±?1.1 years) at diagnosis and after a year of GFD (group 1), 100 CD children (group 2; 47 compliant and 53 non-compliant) in follow-up and 25 healthy controls.

Results: Untreated CD (n?=?50) children had larger left ventricle end diastolic dimension (35.33?±?0.87 vs. 32.90?±?0.91 mm; p?=?.04), reduced (<55%) left ventricular ejection fraction (20% vs. 0%; p?=?.01) and a higher (>0.6) myocardial performance index (MPI, 66% vs. 0%; p ≤ .01) as compared to controls. Re-evaluation after one year with good dietary compliance showed changes in isovolumic relaxation time (72.5?±?4.2 vs. 50.62?±?2.69; p?=?.0001) and deceleration time (121.05?±?10.1 vs. 99.87?±?8.5; p?=?.02), reflecting improved cardiac diastolic function. GFD compliant patients had lower MPI than non-compliant (0.60?±?.03 vs. 0.66?±?.08; p?=?.04), reflecting improvement in load-independent echocardiographic parameters.

Conclusions: Subclinical cardiac dysfunction is common in CD children at diagnosis. Improvement

in echocardiographic parameters occurs with GFD and non-compliant children continue to have

persistent cardiac dysfunction.     

Effects of diet on the lipid composition of Echinostomacaproni (Trematoda) in ICR mice

High-performance thin-layer chromatography (HPTLC) was used to determine neutral lipids and phospholipids in the intestinal trematode Echinostomacaproni from experimentally infected ICR mice fed a high-fat diet (hen's egg yolk) as compared with worms from mice fed a standard laboratory diet. Worms were removed from the hosts at 2, 3, and 4 weeks postinfection (p.i.). Analysis by TLC-densitometry showed significantly greater amounts of triacylglycerols and free sterols at 2, 3, and 4 weeks p.i. in worms from mice on the high-fat diet as compared with worms from mice on the standard laboratory diet. Significantly greater amounts of phosphatidylcholine and phosphatidylethanolamine were found in worms from mice on the high-fat diet as compared with worms from those on the standard diet at 2 weeks p.i. but not at 3 and 4 weeks p.i. The results of this study suggest that the host diet influences the lipid content of E. caproni adults.     

Efficacy and safety of beating heart coronary revascularization coupled with ascending aorta-bifemoral grafting: Analysis of short term results

Introduction  

Coronary Artery Disease (CAD) frequently coexists with Peripheral Vascular Disease (PVD) and poses management issues. When there is a concomitant infrarenal aortic occlusive disease, abdominal aorta is the traditional donor of bypass inflow to the lower limbs. However, the ascending aorta may also be used as the source of inflow to both the femoral and coronary arteries in patients who present with combined CAD and PVD. Here, 5 year follow up results of simultaneous off-pump coronary artery bypass grafting (OPCAB) and Ascending Aorto-Bifemoral Grafting [AABG] are presented and merits of the procedure are discussed.     

Free fibula flap in the reconstruction of mandible: a report of six cases

The defects secondary to surgical ablation of the mandible have far reaching consequences. Speech, respiration, mastication, deglutition and cosmesis are severely affected. Restoring these functions is a challenging task. Till the late eighties, myocutaneous flaps were the rule for mandibular reconstruction and free bone was used to restore bony continuity. In spite of the result being predictable the outcome left much to be desired. There was also a fairly regular crop of complications. Acceptable dental rehabilitation was almost non-existent. With the introduction of free flaps as a consequence of the development of the operating microscope, the field of reconstruction was revolutionized.
