Opportunistic Infections in HIV-Infected Patients Differ Strongly in Frequencies and Spectra between Patients with Low CD4+ Cell Counts Examined Postmortem and Compensated Patients Examined Antemortem Irrespective of the HAART Era.

Objective: AIDS-related mortality has changed dramatically with the onset of highly active antiretroviral therapy (HAART), which has even allowed compensated HIV-infected patients to withdraw from secondary therapy directed against opportunistic pathogens. However, in recently autopsied HIV-infected patients, we observed that associations with a broad spectrum of pathogens remain, although detailed analyses are lacking. Therefore, we focused on the possible frequency and spectrum shifts in pathogens associated with autopsied HIV-infected patients.

Planum temporale analysis via a new volumetric method in autoptic brains of demented and psychotic patients.

Investigations of alterations in brain asymmetry often focus on the planum temporale of patients with schizophrenia. Data also suggest changes in laterality of demented patients associated with a more marked impairment of the left hemisphere. Our study was performed on autoptic brain tissue of 84 patients, out of which there were 25 non-demented non-psychotic controls, 50 demented patients (34 Alzheimer disease, 9 multi - infarct dementia and 7 mixed-type dementia patients) and 9 people with schizophrenia.

Expression of apoptosome pathway-related transcripts in non-small cell lung cancer.

Purpose: Tumour cells killing by cytotoxic therapies largely depends on triggering the intrinsic apoptosome-mediated caspase activation pathway but it had never been evaluated whether the expression of transcripts encoding the core components of apoptosome pathway is altered in non-small cell lung carcinoma (NSCLC).

Methods: We investigated the expression status of several apoptosome pathway-related transcripts including Apaf-1, procaspase-9, -3, -6, -7 and Smac in tumour and lung tissue samples from 65 surgically treated NSCLC patients and in 10 NSCLC cell lines with using real time RT-PCR.

Results: NSCLC tissues and cell lines showed significantly increased expression of procaspase-9, -3, -6 and Smac mRNAs as compared to the lungs and expression of these transcripts was simultaneously upregulated in a subset of NSCLCs belonging to different histopathological type, grade and stage categories.

[The first death from tertian malaria in the Czech Republic].

The authors describe a fatal case of tertian malaria (Plasmodium vivax) imported to the Czech Republic from India. Severe clinical symptoms leading to shock and multi-organ failure are more frequent in tropical malaria (P. falciparum).

[A case of Creutzfeldt-Jakob syndrome with dominant ocular symptoms].

The authors present a rare case of a 46-year-old man with Creutzfeldt-Jacob's disease, its causal agent being an unconventional virus (prion). Ocular symptoms were the first which made the patient see a doctor. The course of the disease with a fatal outcome caused great diagnostic difficulties among a number of specialists.
