Current Mycoplasma pneumoniae outbreak: Don't forget its role in Bickerstaff encephalitis.

Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in children and young adults. It is responsible of a broad array of extrapulmonary manifestations, the most severe affecting the central nervous system. We report a challenging diagnosis of macrolide-resistant M.

Estimating the global reduction in transmission and rise in detection capacity of the novel coronavirus SARS-CoV-2 in early 2020.

To better control the SARS-CoV-2 pandemic, it is essential to quantify the impact of control measures and the fraction of infected individuals that are detected. To this end we developed a deterministic transmission model based on the renewal equation and fitted the model to daily case and death data in the first few months of 2020 in 79 countries and states, representing 4.2 billions individuals.

[Pseudotumoral hepatic tuberculosis. Ultrasonics and x-ray computed tomography apropos of a case].

Results of CT scan and ultrasound exploration were discordant in a patient with the pseudotumoral form of hepatic tuberculosis. Although rare, this localization should not be unrecognized because of the curable nature of the affection. Tissular characterization of lesion was not possible by medical imaging alone and liver puncture-biopsy examination was necessary.

[Calcifying muscular metastases of colonic origin. Apropos of a case localized in the psoas muscle].

A case is reported of calcifying metastases of colon origin localized to psoas muscle. Emphasis is placed on the effectiveness of CT scan and MR imaging and the rarity of this localization. The presence of intra-lesional calcifications as described in hepatic metastases raises the question of the etiopathogenic mechanism and the predictive value of the detection of a calcified mass during the course of colon adenocarcinoma.

[Computerized x-ray tomographic aspects of calcifying hepatic metastases. Incidence of cancer of colorectal origin].

A total of 24 patients with liver metastases of the calcifying type were detected during CT scan imaging for cancer of different primary origin (colorectal, ovarian, mammary, gastric, prostatic, melanoma). These calcifying metastases represented 27% of the 89 liver metastases cases detected, and the incidence of a colorectal origin for these calcifying lesions (20% of cases) appears to be highly significant, their number being relatively larger than reported in previous studies. Identification of liver calcifications of possible diagnostic importance requires a two-stage CT scan investigation, before and after bolus.
