Subacute fatal aluminum encephalopathy after reconstructive otoneurosurgery: a case report.

We report a 52-year-old woman who underwent otoneurosurgery to resect acoustic neurinoma. Bone reconstruction was performed with an aluminium (Al)-containing cement. Six weeks later the patient suffered from loss of consciousness, myoclonic jerks, and persistent grand mal seizures, clinical symptoms that resembled those of lethal dialysis encephalopathy of the 1960s and 1970s.

Transgenic rat hearts expressing a human cardiac troponin T deletion reveal diastolic dysfunction and ventricular arrhythmias.

Objective: Familial hypertrophic cardiomyopathy (FHC) due to mutations of cardiac troponin T (cTnT) is associated with a high frequency of sudden death even in the absence of cardiac hypertrophy. To investigate the causal relationship of cTnT mutations and this particular phenotype, we sought to establish a transgenic rat model for the disease.

Methods: Transgenic rats were generated expressing human wild-type cTnT or two truncated cTnT molecules (del ex16, del ex15/16), resulting from an intron 15 splice donor site mutation previously observed in FHC patients.

Colonic primary large cell lymphoma with marginal zone growth pattern presenting as multiple polyps.

We report a rare case of primary gastrointestinal lymphoma, stage IE, in a 58-year-old white man who had multiple colonic polyps measuring up to 1 x 1.1 cm. The tumor originated in the marginal zone of the follicles infiltrating the interfollicular spaces.

Bronchoalveolar lavage cell profiles in Wegener's granulomatosis.

Pulmonary involvement due to Wegener's granulomatosis (WG) can present radiologically either as diffuse infiltrates or as nodular and linear opacities. Clinical experience suggest that these radiological patterns are associated with different bronchoalveolar lavage (BAL) cell profiles, but this has not been examined formally. We compared the BAL cell profile in eight WG patients with diffuse infiltrates on chest X-ray, indicative of highly active pneumonitis, with corresponding findings in 37 patients with nodular, linear and focal low-attenuation infiltrates on high-resolution computed tomography (HRCT) which reflected low-grade, mainly interstitial disease.

Tuberous sclerosis with intracardiac rhabdomyoma in a fetus with trisomy 21: case report and review of literature.

A large cardiac rhabdomyoma protruding into the left ventricle was diagnosed in a fetus at 21+2 weeks of gestation by grey-scale echocardiography. Obstruction to left ventricular outflow was ruled out by colour and spectral Doppler echocardiography. No other abnormalities were noted and karyotyping by cordocentesis revealed trisomy 21 (47,XY,+21).
