Central Nervous System Tuberculosis : Etiology, Clinical Manifestations and Neuroradiological Features.

PURPOSE: As a result of multilateral migration and globalization in times of humanitarian crises, western countries face a possible increase in the incidence of central nervous system tuberculosis (CNS TB). The diagnosis of CNS TB is challenging and often delayed due to the manifold and often non-specific presentation of the disease. The aim of this review is to analyze and summarize imaging features and correlated clinical findings of CNS TB. METHODS: The different manifestations of CNS TB are explained and illustrated by characteristic neuroradiological as well as neuropathological findings. An overview on diagnostic and therapeutic approaches is provided. For clarity, tables summarizing the lesion patterns, differential diagnoses and diagnostic hints are added. RESULTS: The CNS TB can be manifested (1) diffuse as tuberculous meningitis (TBM), (2) localized as tuberculoma or (3) tuberculous abscess or (4) in extradural and intradural spinal infections. Information on clinical presentation, underlying pathology and the distinguishing features is demonstrated. The TBM is further described, which may lead to cranial nerve palsy, hydrocephalus and infarction due to associated arteritis of the basal perforators. The differential diagnoses are vast and include other infections, such as bacterial, viral or fungal meningoencephalitis, malignant causes or systemic inflammation with CNS. Complicating factors of diagnosis and treatment are HIV coinfection, multi-drug resistance and TB-associated immune reconstitution inflammatory syndrome (IRIS). CONCLUSIONS: Neurologists and (neuro-)radiologists should be familiar with the neuroradiological presentation and the clinical course of CNS TB to ensure timely diagnosis and treatment.

Women show a higher level of anxiety during IVF treatment than men and hold different concerns: a cohort study.

PURPOSE: The aim of the present study was to determine levels of anxiety during the course of IVF treatment and gender differences in treatment anxiety. METHODS: This was a prospective cohort study set in a university affiliated, tertiary care IVF program. 119 women and 82 men entering the clinic to undergo IVF treatment filled out questionnaires containing the Spielberger state-trait-anxiety-inventory (STAI) as well as further items on specific stress triggers. RESULTS: Women and men undergoing IVF have higher levels of anxiety than the average population in Germany. Overall, female patients show significantly higher values (mean ± SD) for state and trait anxiety (47.4 ± 11.0 and 40.1 ± 9.85) than their male partners (41.4 ± 9.66 and 35.3 ± 8.57, p < 0.01). Over the course of several IVF cycles, average STAI scores increased for both genders. When asked about specific stress factors on a 4-point scale from 'not at all' to 'very much so', women report as their main anxiety the failure to achieve a successful pregnancy, scoring significantly higher on questions like 'obtaining a negative pregnancy test' (3.24 ± 0.82, p < 0.01) and 'disclosure of infertility' (3.02 ± 1.10, p < 0.001). Their male partners are more concerned about the health risks the women have to take such as 'side effects of ovarian stimulation' (2.55 ± 0.77, p = 0.002) and 'bleeding or infection after the oocyte aspiration' (2.58 ± 0.84, p = 0.007). Both genders indicated to be very little worried about multiple pregnancies after IVF. CONCLUSIONS: Women show a higher level of anxiety during IVF treatment and hold different concerns. Neither of the sexes appears to be familiar with the risks associated with multiple pregnancies, a matter that should better be addressed.
