Diffuse Primary Angiosarcoma of the Pleura: A Case Report and Review of the Literature
Primary pleural angiosarcoma is an extremely rare tumor. We report the case of a patient who presented with recurrent
massive bilateral hemothoraxes. Although thoracoscopy was performed, biopsy samples of the pleura were inconclusive.
The delayed onset of skin metastases led to the diagnosis of angiosarcoma, however the patient died from pleuropulmonary
progression before treatment could be started. We review the literature of primary pleuropulmonary angiosarcoma and
discuss its treatment modalities
Successful Treatment of a Granulocytic Sarcoma of the Uterine Cervix in Complete Remission at Six-Year Follow-Up
Background. Localized granulocytic sarcoma of the uterine cervix in the absence of acute myelogenous leukemia (AML) at presentation is very rare, its diagnosis is often delayed, and its prognosis almost always ominous evolving into refractory AML. Case. We present the case of a 30-year-old woman with vaginal bleeding and a large cervical mass. Further evaluation confirmed the presence of a granulocytic sarcoma but failed to reveal systemic involvement. Results. AML type chemotherapy followed by radiotherapy of the uterus led to a durable complete remission. She remains in complete remission six years after diagnosis. Conclusion. Granulocytic sarcoma of the cervix is a rare entity for which early intensive AML type therapy is effective
Influenza vaccination of healthcare workers in acute-care hospitals: a case-control study of its effect on hospital-acquired influenza among patients
<p>Abstract</p> <p>Background</p> <p>In acute-care hospitals, no evidence of a protective effect of healthcare worker (HCW) vaccination on hospital-acquired influenza (HAI) in patients has been documented. Our study objective was to ascertain the effectiveness of influenza vaccination of HCW on HAI among patients.</p> <p>Methods</p> <p>A nested case-control investigation was implemented in a prospective surveillance study of influenza-like illness (ILI) in a tertiary acute-care university hospital. Cases were patients with virologically-confirmed influenza occurring ≥ 72 h after admission, and controls were patients with ILI presenting during hospitalisation with negative influenza results after nasal swab testing. Four controls per case, matched per influenza season (2004-05, 2005-06 and 2006-07), were randomly selected. Univariate and multivariate conditional logistic regression models were fitted to assess factors associated with HAI among patients.</p> <p>Results</p> <p>In total, among 55 patients analysed, 11 (20%) had laboratory-confirmed HAI. The median HCW vaccination rate in the units was 36%. The median proportion of vaccinated HCW in these units was 11.5% for cases vs. 36.1% for the controls (<it>P </it>= 0.11); 2 (20%) cases and 21 (48%) controls were vaccinated against influenza in the current season (<it>P </it>= 0.16). The proportion of ≥ 35% vaccinated HCW in short-stay units appeared to protect against HAI among patients (odds ratio = 0.07; 95% confidence interval 0.005-0.98), independently of patient age, influenza season and potential influenza source in the units.</p> <p>Conclusions</p> <p>Our observational study indicates a shielding effect of more than 35% of vaccinated HCW on HAI among patients in acute-care units. Investigations, such as controlled clinical trials, are needed to validate the benefits of HCW vaccination on HAI incidence in patients.</p

Muscle fibre ontogenesis in farm animal species
In farm animals (bovine, ovine, swine, rabbit and poultry), muscle fibre characteristics
play a key role in meat quality. The present review summarises the knowledge on muscle
fibre characteristics and ontogenesis in these species. Myofibre ontogenesis begins very
early during embryonic life, with the appearance of two or three successive waves
of myoblasts which constitute the origin of the different types of muscle fibres.
In small animals (rodents and poultry), a primary and a secondary generation of fibres
arise respectively during the embryonic and foetal stages of development. In the largest
species (bovines, sheep, pigs) a third generation arises in the late foetal or early
postnatal period. Following these two or three waves of myogenesis, the total number
of fibres is fixed. This occurs during foetal life (bovines, ovines, pigs and poultry)
or during the first postnatal month in rabbits. Contractile and metabolic differentiation
proceed by steps in parallel to myogenesis and are partially linked to each other.
In bovines and ovines, the main events occur during foetal life, whereas they occur
soon after birth in the pig, poultry and rabbit, but some plasticity remains later
in life in all species. This comparative survey shows that the cellular processes
of differentiation are comparable between species, while their timing is usually
species specific
