A patient with myasthenia gravis and a large arachnoid cyst - report of a case.

Myasthenia gravis is a chronic autoimmune disease characterized by weakening of voluntary muscles during the day and a marked restitution of function during the night and after rest. The symptoms may worsen over days or weeks, sometimes even in a few hours, and are usually well controlled by appropriate therapy. Arachnoid cysts are congenital or acquired deformities of the arachnoid membrane and are usually too small to cause distinct clinical symptomatology.

MMP-2 -1575G/A polymorphism modifies the onset of optic neuritis as a first presenting symptom in MS?

Previous studies show altered activities of matrix metalloproteinase (MMP)-2 and MMP-9 in serum and cerebrospinal fluid of multiple sclerosis (MS) and neuromyelitis optica (NMO) patients. Optic neuritis (ON) is a common symptom of both disorders. Here we investigated the impacts of MMP-2 -1575G/A and MMP-9 -1562 C/T gene polymorphisms on disease phenotype in 100 MS patients with ON as a first symptom and 376 MS patients with other initial symptomatology.

Ganglia/nerve fibers ratio correlates with the need for surgery in patients diagnosed with Hirschsprung's disease allied disorder (HAD).

Treatment in Hirschsprung's disease allied disorder (HAD) is surgical. In HAD, surgery is always a question. We investigated the value of ganglia/nerve fibers ratio in prediction of the need for invasive procedures in HAD.

Recombinant mouse cytomegalovirus expressing a ligand for the NKG2D receptor is attenuated and has improved vaccine properties.

Human CMV (HCMV) is a major cause of morbidity and mortality in both congenitally infected and immunocompromised individuals. Development of an effective HCMV vaccine would help protect these vulnerable groups. NK group 2, member D (NKG2D) is a potent activating receptor expressed by cells of the innate and adaptive immune systems.
