Stenting in Brain Hemodynamic Injury of Carotid Origin Caused by Type A Aortic Dissection: Local Experience and Systematic Literature Review.

In this study, we report our local experience of type A aortic dissections in patients with cerebral malperfusion treated with carotid stenting before or after aortic surgery, and present a systematic literature review on these patients treated either with carotid stenting (CS) before or after aortic surgery (AS) or with aortic and carotid surgery alone (ACS). We report on patients treated in our center with carotid stenting for brain hemodynamic injury of carotid origin caused by type A dissection since 2018, and a systematic review was conducted in PubMed for articles published from 1990 to 2021. Out of 5307 articles, 19 articles could be included with a total of 80 patients analyzed: 9 from our center, 29 patients from case reports, and 51 patients from two retrospective cohorts.

Dendrimer nanotherapy for severe COVID-19 attenuates inflammation and neurological injury markers and improves outcomes in a phase2a clinical trial.

Hyperinflammation triggered by SARS-CoV-2 is a major cause of disease severity, with activated macrophages implicated in this response. OP-101, a hydroxyl-polyamidoamine dendrimer--acetylcysteine conjugate that specifically targets activated macrophages, improves outcomes in preclinical models of systemic inflammation and neuroinflammation. In this multicenter, randomized, double-blind, placebo-controlled, adaptive phase 2a trial, we evaluated safety and preliminary efficacy of OP-101 in patients with severe COVID-19.

Specific increase of Fusobacterium in the faecal microbiota of neonatal calves infected with Cryptosporidium parvum.

The faecal microbiota plays a critical role in host health, with alterations in the human faecal microbial composition associated with various conditions, particularly diarrhoeal diseases. However, little is known about microbial changes during cryptosporidiosis, one of the most important diarrhoeal diseases caused by protozoa in cattle. In this study, alterations in the faecal microbiota of neonatal calves as a result of Cryptosporidium parvum infection were investigated on a C.

First detection of Allobilharzia visceralis (Schistosomatidae, Trematoda) from Cygnus cygnus in Japan.

Adult schistosomes were detected in the veins or capillaries of the large intestine, mesentery, liver, and adrenal glands in eight of 13 whooper swans (Cygnus cygnus) examined in Iwate Prefecture, Japan. However, neither eggs nor severe tissue injuries were observed in any of the swans. The schistosomes were definitively identified as Allobilharzia visceralis based on the nucleotide sequences of the ribosomal internal transcribed spacer (ITS) region.

Novel methods for the molecular discrimination of Fasciola spp. on the basis of nuclear protein-coding genes.

Fasciolosis is an economically important disease of livestock caused by Fasciola hepatica, Fasciola gigantica, and aspermic Fasciola flukes. The aspermic Fasciola flukes have been discriminated morphologically from the two other species by the absence of sperm in their seminal vesicles. To date, the molecular discrimination of F.

Molecular epidemiological analyses of Cryptosporidium parvum virus 1 (CSpV1), a symbiotic virus of Cryptosporidium parvum, in Japan.

We show that Cryptosporidium parvum virus 1 (CSpV1), a member of the family Partitiviridae, genus Cryspovirus that can infect Cryptosporidium parvum, is a new candidate for high-resolution tool for tracing C. parvum. CSpV1 was detected in all C.

Molecular characterization of Cryptosporidium parvum detected in Japanese black and Holstein calves in Iwate Prefecture and Tanegashima Island, Kagoshima Prefecture, Japan.

Cryptosporidium oocysts were found in 43 out of 77 calves from two farms in Iwate Prefecture and nine farms on Tanegashima Island, Kagoshima Prefecture, Japan. The DNA fragments of 18S ribosomal RNA (18S rRNA) gene were amplified by a nested PCR from 43 oocyst-positive as well as one oocyst-negative samples. All of them were precisely identified as C.

Molecular characterization of Cryptosporidium parvum from two different Japanese prefectures, Okinawa and Hokkaido.

Infectious diarrhea is the most frequent cause of morbidity and mortality in neonatal calves. Cryptosporidium parvum is one of the main pathogens associated with calf diarrhea. Although diarrhea is a symptom of infection with various pathogens, investigations to detect the types of pathogens have never been performed in Japan.

[Prevalence of the bacteria causing diarrea in a Rosario Hospital, Argentina].

Bacterial agents causing diarrea in patients attended in a hospital of Rosario, Argentina. The frequency of bacterial agents causing diarrhea can vary in patients of different areas, and through the time. In an epidemiological surveillance we studied 304 patients with diarrheal diseases looking for Salmonella enterica, Shigella spp, Campylobacter spp, Aeromonas spp, Yersinia enterocolitica, and diarrheogenic Escherichia coli.

[Late-presenting congenital diaphragmatic hernia: a possible cause of sudden respiratory distress in children].

OBJECTIVE: To emphasize that congenital defects of the diaphragm should be considered in the differential diagnosis of sudden onset of respiratory distress in children. MATHOD: Two illustrative cases of children (aged 2 years) with late presenting congenital diaphragmatic hernia who developed sudden respiratory distress and were managed at the University Hospital of Santa Maria are reported. The medical literature was reviewed to identify cases reports and other articles related to late presenting congenital diaphragmatic hernia.

The paracentral visual field in multiple sclerosis: evidence for a deficit in interneuronal spatial summation?

A visual complaint such as blurred or "washed-out vision" can be one of the early signs of multiple sclerosis (MS). Although visual deficits are commonly attributed to optic nerve demyelination even with preserved visual acuity, the results of a considerable number of visual studies are inconsistent with this interpretation [Camisa, Mylin, & Bodis-Wollner, Annals of Neurology 10 (1981) 532-539; Regan & Neima, British Journal of Ophthalmology 68 (1984) 310-315]. However, a retinal axonal (nerve fiber layer) defect can be detected in some eyes, this is not the rule.

Hospital transmission of multidrug-resistant Mycobacterium tuberculosis in Rosario, Argentina.

Multidrug-resistant tuberculosis has emerged over the last two years at Carrasco Hospital, located in Rosario city. Nosocomial transmission among 7 AIDS patients admitted into the same ward between June and December/94 was supported by temporal clustering of cases, matching drug susceptibility, and identical IS6110 fingerprints. Among 8 non-HIV chronic cases without evidence of reciprocal contact outside the hospital, two additional clusters of 2 and 4 cases, respectively, were identified.

Spinocerebellar ataxia type 1 and Machado-Joseph disease: incidence of CAG expansions among adult-onset ataxia patients from 311 families with dominant, recessive, or sporadic ataxia.

The ataxias are a complex group of diseases with both environmental and genetic causes. Among the autosomal dominant forms of ataxia the genes for two, spinocerebellar ataxia type 1 (SCA1) and Machado-Joseph disease (MJD), have been isolated. In both of these disorders the molecular basis of disease is the expansion of an unstable CAG trinucleotide repeat.

Neuropsychological test performance in patients with dominantly inherited spinocerebellar ataxia: relationship to ataxia severity.

To determine whether the cognitive status of patients with dominantly inherited spinocerebellar ataxia (DSCA) might be related to neurologic severity, we administered a comprehensive neuropsychological test battery to 43 patients with DSCA, ranging in ataxia severity from mild to end-stage. As compared with the controls, the mildly ataxic patients scored normally or close to normal as a group on all of the neuropsychological tests. In contrast, approximately one-half of the moderately and all of the severely ataxic patients showed poor performance, independent of age, Hamilton Rating Scale for Depression score, or education, on the Wisconsin Card Sorting Test, suggesting impaired executive system function.

Etiology of syncope in 100 patients with associated pale facial appearance.

Since publication and discussion of the original patients, I have continued to evaluate patients with loss or near loss of consciousness using the patient's facial color as a guide to underlying etiology. This has consistently provided a quick, reliable method for trying to sort through these difficult cases. Others have similarly noted value of a pale, ashen facial color in diagnosing patients with transient loss of consciousness.

Women at risk of family violence.

Presented here are the basic, core picture and pathognomonic features of spouse (or partner) violence, stripped of obscuring traditional, often male-dominated misinformation. Spouse abuse, like other forms of intentional injury or violence, should no longer be considered tolerable or "normal." It represents a form of psychopathology, corrupting the family emotional setting, provoking human anguish and even death.

Transient ischemic attack (TIA) secondary to subdural hematoma.

Subdural hematomas many sometimes clinically resemble Transient Ischemic Attacks (TIA's). We present three cases which were initially evaluated for, diagnosed as having and were treated for TIA's, but later were found to have subdural hematomas. As in case one, patients with subdurals may have antecedent head trauma which they may or may not recall.

Autosomal dominant spinocerebellar ataxia: locus heterogeneity in a Nebraska kindred.

SCA1 is an adult-onset autosomal dominant ataxia that is genetically linked to loci on chromosome 6p. A highly informative GT-repeat marker, D6S89, has been closely linked to the SCA1 locus in five large kindreds. We have used this marker to perform linkage analysis in a smaller autosomal dominant ataxia family consisting of five generations designated as the Nebraska kindred.

Psychosurgery: a retrospective.

Of the 56 patients within the Yakovlev collection who had undergone psychosurgery 11 (20%) improved, 18 (32%) were either worse or without improvement, and 27 (48%) were without any clinical follow-up. Thus, in retrospect, psychosurgery was perhaps not as successful as once envisioned.
