A 51-year-old man presented with vertigo, slurred speech and left facial droop. He had been previously diagnosed with transient ischaemic attack (TIA) and had a prior lacunar infarct. Imaging showed heavy symmetrical calcification in the globus pallidus, frontal white matter and cerebellar dentate nuclei/deep white matter. The imaging was pathognomonic for Fahr’s disease and diagnosis was confirmed when other secondary causes of hypercalcemia were excluded. Fahr’s disease is a rare, autosomal dominant, neurological condition characterised by primary brain calcification. Patients present with progressive neurological and psychiatric symptoms; commonly, Parkinsonian movement disorders, seizures, headaches, dysarthria, cognitive decline, psychosis and personality changes. There is an association with intracerebral ischaemic events. This case supports a growing body of anecdotal evidence of this association and is the first in which crescendo TIA may be the initial presentation of Fahr’s disease. Referral for genetic counselling and symptomatic relief for neurological symptoms are the main management strategies.

Microglia participate in central nervous system (CNS) development and homeostasis and are often implicated in modulating disease processes. However, less is known about the role of microglia in the biology of the neurovascular unit (NVU). In particular, data are scant on whether microglia are involved in CNS vascular pathology. In this study, we use a mouse model of primary familial brain calcification, Pdgfbret/ret, to investigate the role of microglia in calcification of the NVU. We report that microglia enclosing vessel calcifications, coined calcification-associated microglia, display a distinct activation phenotype. Pharmacological ablation of microglia with the CSF1R inhibitor PLX5622 leads to aggravated vessel calcification. Mechanistically, we show that microglia require functional TREM2 for controlling vascular calcification. Our results demonstrate that microglial activity in the setting of pathological vascular calcification is beneficial. In addition, we identify a previously unrecognized function of microglia in halting the expansion of vascular calcification.

AbstractPrimary familial brain calcification (PFBC) is a neurological condition characterized by the presence of intracranial calcifications, mainly involving basal ganglia, thalamus, and dentate nuclei. So far, six genes have been linked to this condition: SLC20A2, PDGFRB, PDGFB, and XPR1 inherited as autosomal-dominant trait, while MYORG and JAM2 present a recessive pattern of inheritance. Patients mainly present with movement disorders, psychiatric disturbances, and cognitive decline or are completely asymptomatic and calcifications may represent an occasional finding. Here we present three variants in SLC20A2, two exonic and one intronic, which we found in patients with PFBC associated to three different clinical phenotypes. One variant is novel and two were already described as variants of uncertain significance. We confirm the pathogenicity of these three variants and suggest a broadening of the phenotypic spectrum associated with mutations in SLC20A2.

Introduction. The heterotopic gastric mucosal patch or inlet patch is the presence of gastric columnar mucosa outside the stomach, most frequently located in the proximal esophagus. Its manifestations vary from esophageal and extraesophageal reflux symptoms to major complications, most of them being asymptomatic. Aim. To determine the prevalence of cervical heterotopic gastric mucosa in our environment and its association with esophageal and extraesophageal reflux symptoms. Material and methods. Prospective cross-sectional and observational study; consecutive patients who came to our institution between December 2018 and October 2019 for diagnostic upper gastrointestinal videoendoscopy were included, following a questionnaire on clinical manifestations. Results. A total of 1,408 patients were included. In 89 (6.3%), a cervical heterotopic gastric mucosal patch was described. The mean age of the patients without this condition was 54.6 and 55.5 in patients with it. The esophageal symptoms of gastroesophageal reflux (heartburn, regurgitation, and chest pain) in patients with cervical heterotopic gastric mucosa was observed in 40 (44.9% / p = 0.473), 12 (13.5% / p = 0.783) and 4 (4.5% / p = 0.199) patients respectively. The presence of extraesophageal symptoms (globus, chronic cough, dysphonia, and throat clearing) in patients with cervical heterotopic gastric mucosa was: 9 (10.1% / p = 0.011); 7 (7.9% / p = 0.155); 4 (4.5% / p = 0.458) and 9 (10.1% / p = 0.036) respectively. Conclusions. A statistically significant association was found between the presence of cervical heterotopic gastric mucosal patch and symptoms of globus (p = 0.011) and throat clearing (p = 0.036). It could be interpreted that this group of patients would benefit from the research and treatment of this condition with the intention of improving their symptoms.
