Mechanobiological computational model for the development and formation of synovial joints
2019
El desarrollo de las articulaciones sinoviales se debe a diferentes factores genéticos, bioquímicos y mecánicos. Comienza en el brote de las extremidades, que tienen una masa ininterrumpida de células mesenquimales dentro de su núcleo, el blastema esquelético. La mayoría de estas células blastemales se diferencian en condrocitos; sin embargo, algunas de estas células permanecen, sin diferenciar, en el sitio de la futura articulación (interzona). La separación de los rudimentos ocurre con el proceso de cavitación dentro de la interzona. Después de la cavitación, se produce la morfogénesis articular y el hueso toma su forma final. Una vez finalizado el período embrionario, la articulación sin…
Measuring Aksak Rhythm and Synchronization in Transylvanian Village Music by Using Motion Capture
2015
<p>Techniques based on motion capture can be useful in <span><span style="font-size: x-small;">analyzing a wide range of musical styles and practices</span></span>: in this case, Transylvanian village music. We focused on a repertoire known as “Gypsy songs of sorrow”, played by professional Gypsy musicians during parties and celebrations of their own community. Two parameters were the object of study: rhythmic duration, and synchronization between musicians (a violinist and a viola player). Results show that rhythm is a local variant of <em>aksak</em> and is based on two duration units (S=short, L=long) which respect the formula 2:3 &lt; S:L &am…
Serratia marcescens infection or hypoxic-ischaemic encephalopathy in neonates: Is magnetic resonance imaging a problem-solving tool?
2017
To the Editor: We read with great interest the retrospective case series by A Madide and J Smith,[1] describing brain ultrasound (US) findings of neonates with Serratia marcescens hospital-acquired infections. S. marcescens is a Gram-negative organism that frequently colonises neonatal intensive care units (NICUs). This bacterium can cause severe brain infections in neonates, with irreversible neurological damage and long-term neurodevelopmental impairment. The authors conclude that in babies with acute onset of the illness, US scans allow doctors to highlight pathological changes in the brain immediately before the microbiological diagnosis of infection, and to follow the evolution of thos…
Autosomal recessive severe dwarfism in a Sicilian girl: a new form of osteodysplastic primordial dwarfism?
1996
A new type of osteodysplastic primordial dwarfism is delineated in a 5- year-old female child with severe growth retardation of prenatal onset, gross skeletal changes, a non-Seckel facial phenotype, and presumed autosomal recessive inheritance.
Pathomorphology of hereditary sensory neuropathies
1995
Currently, the hereditary sensory neuropathies (HSN) — because of the involvement of the autonomic system recently called HSAN — comprise types I–V predicated on clinical differences. This classification of HSAN I–V seems to be uncontested, at the present time. Morphologically, individual forms I–V only differ in the non-specific loss or lack of myelinated and unmyelinated nerves in varying degrees in that in HSAN II large myelinated axons are most affected, in HSAN IV unmyelinated axons are almost absent; but each HSAN is considered an axonal type of neuropathy. Early onset, slow or no progression of the neuropathic process, and little or no evidence of ongoing degeneration suggest maldeve…
The role of US examination in the management of acute abdomen.
2013
Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. …
Hospital Admissions for Acute Myocardial Infarction Before and After Lockdown According to Regional Prevalence of COVID-19 and Patient Profile
2020
Aim: to evaluate the impact of a nationwide lockdown in France on acute myocardial infarction (AMI) admissions, by patient characteristics and regional prevalence of the pandemic. Methods and Results: We collected data from 21 centres participating in the on-going FRENCHIE registry (NCT04050956), which collects data from all patients admitted for STEMI or NSTEMI within 48 hours of symptom onset. We compared weekly admissions in the 4 weeks preceding and the 4 weeks following institution of the lockdown. We observed a brutal 30% decrease in AMI admissions (24% for STEMI and 36% for NSTEMI, P=0.14) following institution of the lockdown, with similar trends according to gender (30% decrease in…
The comparison of cold-water immersion and cold air therapy on maximal cycling performance and recovery markers following strength exercises
2016
This study examined the effects of cold-water immersion (CWI) and cold air therapy (CAT) on maximal cycling performance (i.e. anaerobic power) and markers of muscle damage following a strength training session. Twenty endurance-trained but strength-untrained male (n = 10) and female (n = 10) participants were randomised into either: CWI (15 min in 14 °C water to iliac crest) or CAT (15 min in 14 °C air) immediately following strength training (i.e. 3 sets of leg press, leg extensions and leg curls at 6 repetition maximum, respectively). Creatine kinase, muscle soreness and fatigue, isometric knee extensor and flexor torque and cycling anaerobic power were measured prior to, immediately afte…
Allergic contact dermatitis in patients with frontal fibrosing alopecia: An international multi‐center study
2020
Frontal fibrosing alopecia (FFA) mainly affects the anterior hairline and eyebrows and its etiology and associated factors remain obscure. The aim of this study was to evaluate the allergic contact dermatitis with patch test in patients with FFA. In this prospective study, 20 patients with FFA and 24 age and sex-matched healthy individuals were evaluated with patch testing. Diagnosis was made histologically, clinically and based on dermoscopic findings. Demographic data, age of onset, disease duration and FFA severity index are evaluated in all patients. Positive patch test reaction to one or more allergen was observed in 65% of patients while it was 37.5% in control group (P = .003). There…
Concepts for the treatment of Alzheimer's disease: molecular mechanisms and clinical application
2005
To date, various strategies have been developed in order to prevent or to slow down the progression of Alzheimer's disease (AD). Despite the medical need for an effective therapeutic treatment of AD, progress towards this goal is painstakingly slow. Although AD is the most common neurodegenerative disorder and a large amount of primary basic and clinical research has been performed already, it appears very difficult to identify appropriate targets, which would promise fast, effective and safe strategies to combat the disease onset and progression. In this review, we present some of clinically applied treatment options, which may improve AD symptoms for a short period but so far lack the abi…
