Background and Purpose:
We aimed to investigate the rate of hospital admissions for cerebrovascular events and of revascularization treatments for acute ischemic stroke in Italy during the coronavirus disease 2019 (COVID-19) outbreak.
Methods:
The Italian Stroke Organization performed a multicenter study involving 93 Italian Stroke Units. We collected information on hospital admissions for cerebrovascular events from March 1 to March 31, 2020 (study period), and from March 1 to March 31, 2019 (control period).
Results:
Ischemic strokes decreased from 2399 in 2019 to 1810 in 2020, with a corresponding hospitalization rate ratio (RR) of 0.75 ([95% CI, 0.71–0.80]
P
<0.001); intracerebral hemorrhages decreased from 400 to 322 (hospitalization RR, 0.81 [95% CI, 0.69–0.93];
P
=0.004), and transient ischemic attacks decreased from 322 to 196 (hospitalization RR, 0.61 [95% CI, 0.51–0.73];
P
<0.001). Hospitalizations decreased in Northern, Central, and Southern Italy. Intravenous thrombolyses decreased from 531 (22.1%) in 2019 to 345 in 2020 (19.1%; RR, 0.86 [95% CI, 0.75–0.99];
P
=0.032), while primary endovascular procedures increased in Northern Italy (RR, 1.61 [95% CI, 1.13–2.32];
P
=0.008). We found no correlation (
P
=0.517) between the hospitalization RRs for all strokes or transient ischemic attack and COVID-19 incidence in the different areas.
Conclusions:
Hospitalizations for stroke or transient ischemic attacks across Italy were reduced during the worst period of the COVID-19 outbreak. Intravenous thrombolytic treatments also decreased, while endovascular treatments remained unchanged and even increased in the area of maximum expression of the outbreak. Limited hospitalization of the less severe patients and delays in hospital admission, due to overcharge of the emergency system by COVID-19 patients, may explain these data.
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are caused in the majority of cases by deletions of the DMD gene and are readily detectable in affected males by multiplex polymerase chain reaction (PCR). However, different approaches must be used for the identification of female carriers, in which deletions are not detectable by PCR, because of the presence of a normal X chromosome. In this study, we used the multiple ligation probe amplification (MLPA) tool for the identification of female carriers of DMD deletions or duplications in 12 families with a single affected male, 10 of which were previously diagnosed as carriers of a DMD rearrangement, and the remaining two as having an unknown disease-causing mutation. In all the investigated affected males, MLPA analysis confirmed the presence of a DMD rearrangement, and in six of them allowed the refinement of the breakpoints. In 12 female relatives of the affected patients, MLPA analysis showed a DMD deletion or duplication, confirming their carrier status. Two of these were the mother and the sister of a patient whose disease-causing mutation was not known. MLPA analysis thus proved to be an useful tool for the analysis of both affected males and females carriers of DMD rearrangements in cases in which the disease-causing mutation in the affected male was not known, providing useful information for the genetic counselling of the family.
A 20-year-old man with mild myopathy, external ophthalmoparesis, epilepsy, and diffuse white matter hyperintensity in the brain on magnetic resonance imaging had partial merosin deficiency in muscle and absent merosin in the endoneurium. Motor and sensory nerve conduction velocities were slow. Nerve biopsy showed reduction of large myelinated fibers, short internodes, enlarged nodes, excessive variability of myelin thickness, tomacula, and uncompacted myelin, but no evidence of segmental demyelination, naked axons, or onion bulbs. Thus, in congenital muscular dystrophy, merosin expression may be dissociated in different tissues, and the neuropathy is sensory-motor and due to abnormal myelinogenesis.
The 2019 new coronavirus (SARS-CoV-2) is a novel respiratory virus which has increasingly spread all over the world. Although the predominant clinical presentation is represented by respiratory symptoms, neurological manifestation of SARS-CoV-2 is being increasingly recognized. In the present report, we present a case of post SARS-CoV-2 autoimmune encephalitis associated with a new-onset refractory status epilepticus (NORSE).
