Over the last 10 years, 17 patients (13 males and 4 females) diagnosed as having classical polyarteritis nodosa (PAN) were treated and followed up in the rheumatology clinic of our institute. The median age and duration of symptoms at presentation were 29 years (range 13-59) and 9.5 months, respectively. Patients prese…

BACKGROUND: Little attention has been given to the reasons for failure to detect adenocarcinoma in situ (AIS) of the uterine cervix in Papanicolaou (Pap) smears. In the current study, the authors examined a series of screening or diagnostic errors in cases in which the final histologic diagnosis was either AIS or AIS c…

BACKGROUND: Scleroderma (SSc) patients with active interstitial lung disease (ILD) experience a decline in lung function and increased mortality; cyclophosphamide (CYC) therapy may stabilize lung function at one and two years follow-up. Long-term lung function and survival outcomes of SSc patients with ILD following CY…

In 2019, Italian National Institute of Health established an external quality assessment program (EQA) to evaluate the performance of oral fluid testing for classical and new psychoactive substances by laboratories participating in the National Early Warning System collaborative centres. This report presents the result…

To assess survival of ALS patients in general and in selected demographic and clinical subgroups comparing two periods (1998-2000 vs. 2008-2010).Newly diagnosed adults resident of Lombardy, Northern Italy from a population-based registry were included. Data were collected on age at diagnosis, sex, site of onset, diagno…

PURPOSE: The aim was to investigate the effects of extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA) and compare the results with those of in-hospital cardiac arrest (IHCA). METHODS: We analyzed our extracorporeal membrane oxygenation (ECMO) results for patients who received…

BACKGROUND: To determine whether single-stage, growth-friendly instrumentation with a plate-rod spinal system (PRSS) can substantially correct the deformity of EOS at surgery and continue to rectify the deformity throughout the growth period. METHODS: An observational study of 35 children with EOS treated by PRSS betw…

BACKGROUND: The effect of the Coronavirus Disease 2019 (COVID-19) pandemic on gram-negative bacteria nonsusceptibility to antibiotics is unclear. METHODS: Between January 1, 2010, and December 31, 2021, the respiratory samples of intensive care unit patients at 3 University Hospitals in Brussels were retrieved. B…

OBJECTIVE: To evaluate the accuracy, sensitivity, and specificity of nonecho planar (non-EPI) diffusion-weighted (DW) magnetic resonance imaging (MRI) to detect residual cholesteatoma in children. STUDY DESIGN: Retrospective study. SETTING: Tertiary comprehensive hospital. METHODS: Children operated on for a fi…

The extent and severity of periodontal attachment loss are described for a random sample of 690 dentate community-dwelling adults, aged 65 or over, residing in five counties in North Carolina. In addition, risk indicators for serious levels of loss of attachment and pocket depth in this population are presented. Pocket…

OBJECTIVE: To explore the surgical indications, decompression and fusion method, and fusion level selection of degenerative lumbar scoliosis (DLS) and multi-segment lumbar spinal stenosis. METHODS: Between April 2000 and November 2011, 46 cases of DLS and multi-segment lumbar spinal stenosis were treated with multi-le…

OBJECTIVE: Stereotactic radiosurgery (SRS) has been proposed as an alternative to resection for epilepsy control in patients with cerebral cavernous malformations (CCM) located in critical areas. METHODS: This multicentric, retrospective study evaluated seizure control in patients with a solitary CCM and a history of…

In this paper, we classify scientific articles in the domain of natural language processing (NLP) and machine learning (ML), as core subfields of artificial intelligence (AI), into whether (i) they extend the current state-of-the-art by the introduction of novel techniques which beat existing models or whether (ii) the…

tRNA fragments (tRNA derived fragments or tRFs) are small single stranded RNA molecules derived from pre-tRNAs and mature tRNAs. tRFs have been known for a number of years, but previously they were believed to be not important products of tRNA degradation. tRFs can be unique, like tRF-1 s, or redundant, like tRF-3…

PURPOSE: To report the stability of the functional cure in a chart review of patients with congenital esotropia. METHODS: The charts of 31 patients with congenital esotropia, encountered in 2007-2012 with functional cure, were studied. The stability of the cure and duration of follow-up were determined by comparing th…

OBJECTIVE: Do a factor analysis of the Greene Climacteric Scale for a population of Indian perimenopausal women and establish normative values. METHODS: Five hundred and eighteen women, in the age range 45-55 years, were selected and asked to fill out the Greene Climacteric Scale. RESULTS: The mean age of the women w…

Chiari malformation is a developmental disorder that is often associated with other abnormalities of the cerebrospinal axis. Despite widespread recognition of this association, there is relatively little information on the treatment of these coexisting disorders in the setting of cerebellar tonsillar ectopia. In an eff…

Computational modelling of biological processes and systems has witnessed a remarkable development in recent years. The search-term (modelling OR modeling) yields over 58000 entries in PubMed, with more than 34000 since the year 2000: thus, almost two-thirds of papers appeared in the last 5-6 years, compared to only ab…

For many years it has been assumed that the ontogeny of the mammalian hematopoietic system involves sequential transfers of hematopoietic stem cells (HSCs) generated in the yolk sac blood islands, to successive hematopoietic organs as these become active in the embryo (fetal liver, thymus, spleen and eventually bone ma…
