ABSTRACT Introduction: Tuberculous brain abscess (TBA) is a rare but serious condition. It resembles a pyogenic brain abscess clinically and radiologically and poses a problem in diagnosis and treatment. A final diagnosis is established by smear or culture demonstration of acid fast bacilli (AFB) within the abscess. Here, we report four such cases in our fiveyear study on brain abscesses, along with the different diagnostic modalities used. Materials and Methods: A total of 75 brain abscess pus specimens were collected during neurosurgery, either by burr hole or by craniotomy. These specimens were further subjected to Gram stain, Ziehl-Neelsen (ZN) stain, and conventional microbiological culture. Only those cases which showed presence of AFB on ZN stain along with the growth of Mycobacterium tuberculosis were considered as TBAs. Such TBA cases were further presented along with their In vitro Proton Magnetic Resonance (MR) Spectroscopic findings. Results: Of these four patients, three were males. Though this condition is more commonly seen in immunocompromised patients, three of the patients in this study were immunocompetent. All the four pus specimens showed presence of AFB in the ZN stain. Three of them grew M. tuberculosis as sole isolate. The fourth case was of concomitant tuberculous and pyogenic brain abscess. In vitro Proton MR spectroscopy of the pus specimens showed absence of multiple amino acids at 0.9 ppm, which was found to be hallmark of TBA. One patient died of four. Conclusions: TBA always poses a diagnostic dilemma. ZN stain and conventional microbiological culture for Mycobacteria always help to solve this dilemma. In vitro Proton MR Spectroscopy also seems to have the diagnostic utility.

Introduction: We lack data on the epidemiology and management of brain abscesses in the Middle East. The aim of this study is to report a case series of brain abscesses admitted at a tertiary care center in Lebanon, between January 2008 and December 2018. Methodology: This retrospective study aimed at determining the demographic data, treatment, and correlations between different studied variables with prognosis of patients that received treatment. Results: Forty-one patients (30 males) were included with a median age of 37 years (2-85). The analysis showed that the classic triad of fever, headache and neurologic deficit was only present in 12% of patients on admission. The source of infection was contiguous in 36.5%, post surgical in 32%, and distant in 17% of cases. Stereotactic biopsy was performed in 41.5% of patients, and craniotomy in 19.5%. A microorganism was isolated in 63% of patients (26 cases). The most used antibiotics were carbapenems (46%) and glycopeptides (66%). Eighty percent of patient (33) had a good outcome. A worse prognosis was significantly correlated with immunosuppression and multiple cerebral abscesses. Conclusions: Brain abscess remains a relatively rare condition.

Die verursachenden Erreger von Hirnabszessen variieren in Abhängigkeit von der Grunderkrankung. Typisch sind Mischinfektionen aus Aerobiern und Anaerobiern. Hirnabszesse entwickeln sich meist subakut. Sensibelster Entzündungsparameter im Blut ist das C-reaktive Protein (bei 80–90% der Patien-ten erhöht). Die entscheidende diagnostische Maßnahme ist das kraniale CT ohne und mit Kontrastmittel (KM). Die rasche Kultur von Abszeßinhalt durch Punktion, Drainage oder Abszeßexzision ist entscheidend für die Erregeridentifikation. Eine alleinige Chemotherapie zur Abszeßbehandlung wird nur angewandt, wenn 1. multiple, tief gelegene und/oder sehr kleine Abszesse vorliegen oder 2. sich der Patient in einem so schlechten Allgemeinzustand befindet, daß ihm ein invasiver Eingriff nicht zugemutet werden kann oder 3. eine Hirnphlegmone und kein abgekapselter Abszeß vorliegt. Gebräuchliche operative Verfahren sind die Abszeßaspiration (meist nach stereotaktischer Abszeßpunktion), die offene Kraniotomie mit Abszeßexzision und die offene Abszeßevakuation ohne Kapselentfernung. Für die ungezielte Chemotherapie vor Erregernachweis bevorzugen wir die Kombination von Cefotaxim (3×2–4 g/d i.v.) mit Metronidazol (3–4×0,5 g/d i.v.). Kortikosteroide sind indiziert, wenn der Prozeß raumfordernd ist und eine Herniation droht oder multiple Abszesse vorliegen, die nur teilweise operativ angehbar sind, oder Hirnregionen mit besonderer Ödemneigung betroffen sind.

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.
