[First occurrence of an organic manic schizophreniform syndrome followed by catatonia induced by anti-NMDA-receptor encephalitis]

We report on a 39-year-old female patient who developed catatonia after there had been schizomanic symptoms in the six months before. At admission the patient exhibited catatonia, a tetraspastic syndrome and focal epileptic seizures. The cranial MRI revealed bilateral subcortical hyperintense lesions which took up contrast agent. Examination of the cerebrospinal fluid disclosed a lymphocytic pleocytosis and autochthone oligoclonal bands. In the serum autoantibodies against the NMDA-NR-1 receptor were reproducibly detected. A detailed search for a tumour was negative. In detail, we could exclude a neoplasm of the ovaries which is often present in the paraneoplastic type of anti-NMDA-receptor encephalitis. Therefore we assume an autoimmune, not paraneoplastic, encephalitis in our patient. The symptoms improved significantly after an immunosuppressive therapy - initially with glucocorticoids followed by rituximab - had been initiated. This case illustrates that an autoimmune encephalitis should be looked for when first psychotic symptoms occur.

Mobile stroke unit for diagnosis-based triage of persons with suspected stroke

BACKGROUND

In this feasibility study, we tested whether prehospital diagnostic stroke workup enables rational decision-making regarding treatment and the target hospital in persons with suspected stroke.

METHODS

A mobile stroke unit that delivers imaging (including multimodal brain imaging with CT angiography and CT perfusion), point-of-care-laboratory analysis, and neurologic expertise directly at the emergency site was analyzed for its use in prehospital diagnosis-based triage of suspected stroke patients.

RESULTS

We present 4 complementary cases with suspected stroke who underwent prehospital diagnostic workup that enabled direct diagnosis-based treatment decisions and reliable triage regarding the most appropriate medical facility for that individual, e.g., a primary hospital vs specialized centers of a tertiary hospital.

CONCLUSIONS

This preliminary report demonstrates the feasibility of prehospital diagnostic stroke workup for immediate etiology-specific decision-making regarding the necessary time-sensitive stroke treatment and the most appropriate target hospital.

Circulating serotypes and antimicrobial sensitivity of Streptococcus pyogenes isolates from children in Cyprus

The most common T-serotypes among group A streptococci (n = 88) isolated from pharyngeal samples of children referred to a tertiary hospital in Cyprus for pharyngitis or scarlet fever during a 14-month period (2003-2004) were T28 (25%), T8/25/Imp19 (22.7%) and T12 (9.1%). All 88 isolates were sensitive to penicillin and clindamycin, but 1.1% and 18.2% of isolates were resistant to erythromycin and tetracycline, respectively. Macrolide consumption was estimated at 1.7 defined daily doses/1000 inhabitants/day. The low percentage of resistance to macrolides may have been related, at least in part, to the low consumption of macrolides.
