The microbiological, clinical and radiological findings of cerebral tuberculomas in four patients with and in five patients without HIV infection were compared. The study was carried out during the last 14 years. The CT scans were analyzed in a blinded fashion. Cerebral tuberculoma in HIV-negative patients was clinically characterized by seizures, while in HIV-positive patients this finding was absent. All four HIV-infected patients had headache and fever and their CSF showed lymphocytic meningitis. Two HIV-negative and three HIV-positive patients had concurrent extracerebral tuberculosis. In HIV-infected patients, the cerebral tuberculoma was a secondary finding of disseminated tuberculosis. In our small patient samples, the cerebral tuberculoma presented as spontaneous hypodense cerebral lesions in all the HIV-positive patients but as a hyperdense cerebral lesion in the HIV-negative patients. Two patients of each group had ring enhancement lesions. Cerebral tuberculoma was diagnosed in about 4 weeks for HIV-positive patients, but took some 16 weeks for HIV-negative patients, the latter being first suspected of having a cerebral tumor or bacterial abscess. Diagnostic craniotomy was thus necessary for the HIV-negative patients. One patient of each group died as a consequence of cerebral tuberculoma, all the remaining patients improved with treatment.

Aims There is little information on the familial nature of dyslipidemias in the Spanish population. This knowledge could have potential diagnostic and treatment implications. The objective of the GALIPEMIAS study was to determine the prevalence of familial dyslipidemia in Galicia, as well as determine the degree of lipid control in the participants. Prevalence of atherosclerotic cardiovascular disease (ASCVD) was also estimated. This paper presents the design, methodology and selected preliminary results. Methodology A cross‐sectional study was performed in the population aged ≥18 years using cluster sampling and then random sampling. A sample of 1000 subjects was calculated and divided into three sequential phases with a specific methodology for each one. Phase I: selection of subjects from the general population and collection of informed consent documents; Phase II: collection of data from the digital clinical history to select subjects with dyslipidemia according to study criteria; Phase III: personal interview, blood analysis, family tree, and definitive diagnosis of dyslipidemia. Prevalence of different diseases and active medication was analysed. Corrected prevalence (to the reference population) of different risk factors and ASCVD was estimated. Results Phase I participation was 89.5%. We extracted complete information from 93% of the participants (Phase II). According to the study′s own criteria, 56.5% (n = 527) of the participants had some form of dyslipidemia and almost 33.7% of them had familial dyslipidemia with autosomal dominant inherit pattern. The corrected prevalence of ASCVD was 5.1% (95% CI 3.1‐7.2). Conclusions Dyslipidemia was the most prevalent cardiovascular risk factor in our population with an autosomal dominant inheritance pattern in one out of every three dyslipidemia cases. Approximately, 5.1% of the sample population aged ≥18 has suffered an episode of ACVD.
