Background and purpose: The purpose of this study was to investigate the 5‐year risk of a third bleeding event in cavernous malformations (CMs) of the central nervous system. Methods: Patients with cerebral or spinal CMs treated between 2003 and 2021 were screened using our institutional database. Patients with a complete magnetic resonance imaging dataset, clinical baseline characteristics, and history of two bleeding events were included. Patients who underwent surgical CM removal were excluded. Neurological functional status was obtained using the modified Rankin Scale score at the second and third bleeding. Kaplan–Meier and Cox regression analyses were performed to determine the cumulative 5‐year risk for a third haemorrhage. Results: Forty‐two patients were included. Cox regression analysis adjusted for age and sex did not identify risk factors for a third haemorrhage. 37% of patients experienced neurological deterioration after the third haemorrhage (p = 0.019). The cumulative 5‐year risk of a third bleeding was 66.7% (95% confidence interval [CI] 50.4%–80%) for the whole cohort, 65.9% (95% CI 49.3%–79.5%) for patients with bleeding at initial diagnosis, 72.7% (95% CI 39.3%–92.7%) for patients with a developmental venous anomaly, 76.9% (95% CI 55.9%–90.3%) for patients with CM localization to the brainstem and 75% (95% CI 50.6%–90.4%) for patients suffering from familial CM disease. Conclusions: During an untreated 5‐year follow‐up after a second haemorrhage, a significantly increased risk of a third haemorrhage compared to the known risk of a first and second bleeding event was identified. The third bleeding was significantly associated with neurological deterioration. These findings may justify a surgical treatment after a second bleeding event. [ABSTRACT FROM AUTHOR]

Background: Whereas until 2003 Lymphogranuloma venereum (LGV) was rare in industrialised countries, there have been increasing reports of cases of LGV proctitis in men having sex with men (MSM) over the last six years in Europe, America and Australia., Patients and Methods: After the alarming message from the Netherlands in 2003, physicians in a dermatological and STI private clinic in Zurich started examining rectal swabs from patients with proctitis for LGV serovars of C. trachomatis on a regular basis. A test system based on PCR with sequencing and databank comparison was used. Clinical files of all patients with proctitis observed in this time period were examined., Results: Since 2003 twelve cases of proctitis, all in MSM, caused by the LGV serovar L2 C. trachomatis were observed. Of the overall 11 patients the majority were HIV positive and only 2 were HIV negative. Only one patient reported previous sexual contacts outside Europe (Thailand) as the likely place of infection. The clinical presentation was characterised by anorectal pain, discharge, tenesmus and change in stool frequency. Four patients were successfully treated with a single dose of 1 g azithromycin. In all seven cases treated with doxycycline 2 x 100 mg for 10-20 days clinical cure and a negative PCR result after treatment were observed, except for one patient lost to follow-up., Conclusions: Zurich has not been spared by the recent outbreaks of LGV proctitis in MSM. Anorectal LGV infections may progress to severe destructive changes, with formation of granulomas, strictures, and perirectal abscesses. Increased awareness of this problem and establishment of reliable diagnostic tools are required.
