BACKGROUND: Although different studies associated sleep deprivation with systemic inflammatory changes, the effect of sleep duration on the pathology of allergic chronic diseases is poorly understood. OBJECTIVE: To evaluate the influence of sleep deprivation on allergen-induced pulmonary inflammation. METHODS: Ovalbumin (OVA)-sensitized C57BL/6 mice were exposed to a first set of intranasal OVA challenge under sleep deprivation (SD) or healthy sleep (HS) conditions followed by a second OVA challenge, one week apart...

Physicians can assess the risk of fracture based on bone density (BMD) and several risk factors. Some of them and BMD are incorporated into FRAX, an assessment tool that estimates the 10-years probability of fracture. BMD didn't take into account the microarchitecture. TBS is a texture parameter related to bone microarchitecture. A low TBS is associated with a history of fracture and the incidence of new fracture independently of BMD, clinical risk factors and FRAX. TBS is yet integrated in the FRAX tool, and this effect is of greatest utility for individuals who are close to an intervention threshold...

REVIEW
Federica Vanoni, Francesca Minoia, Clara Malattia
In the past years, pediatric rheumatology has seen a revolution in the treatments for rheumatic diseases, particularly juvenile idiopathic arthritis. Even if nonsteroidal anti-inflammatory drugs (NSAID), intra-articular corticosteroids (IAC) injections, and methotrexate remain the mainstay of the treatment for JIA patients, in aggressive disease, these treatments may be not sufficient to reach disease remission and to prevent long-term disability. Comprehension of immunological mechanisms involved in the pathogenesis of the diseases allowed to conceive new drugs targeting specific steps of the immune response...

Vedolizumab is a humanized IgG1 monoclonal antibody that selectively blocks the lymphocyte integrin α4β7 and prevents its interaction with endothelial adhesion molecules and subsequent transmigration to the gastrointestinal tract. The drug was approved in 2014 for the induction and maintenance treatment of ulcerative colitis and moderate to severe Crohn's disease that is refractory or intolerant to conventional treatment with corticoids and immunosuppressants and/or anti-TNFα drugs. However, inflammatory bowel disease has a variable behavior following liver transplant...

Evangelia Passia, Stéphane Genevay
The efficacy of spinal injection for chronic spinal pain is dubious for most conditions. They are however frequently prescribed. Side effects are poorly reported in the literature. In addition to benign and transient problems, serious and lethal side effects have been reported due to infection, hematoma or central and spinal cord infarctions which could be related to intravascular injection of corticoids. Although their frequency is excessively low, they should be discussed with every patient before prescription and should be mentioned in the consent form...

BACKGOUND AND IMPORTANCE: Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare fibrosing inflammatory process involving the dura mater. Currently, there is no consensus on the treatments for IHCP, and the usefulness of immunosuppressive agents as a first-line option remains controversial. Cerebral venous sinus occlusion (CVSO) and cerebral venous sinus thrombosis (CVST) secondary to IHCP, which may cause progressive intracranial hypertension and venous obstructive parenchymal lesions, make the diagnosis and treatment of IHCP more complicated...

Two-step one-pot microbial transformation enables obtaining of valuable steroids that are difficult to produce chemically. Here we describe a method for obtaining 11α-hydroxyandrost-4-ene-3,17-dione (11α-HAD) from cheap and available natural sterols (phytosterols or cholesterol).11α-HAD is a primary adrenal steroid in mammals and also a key precursor in the syntheses of halogenated corticoids. Conventional routes for its obtaining are based on chemical synthesis, or microbial hydroxylation of androst-4-ene-3,17-dione (AD)...

Rodent models provide valuable insight into mechanisms that underlie vulnerability to adverse effects of early-life challenges. Few studies have evaluated sex differences in anxiogenic or depressogenic effects of adolescent social stress in a rodent model. Furthermore, adolescent stress studies often use genetically heterogeneous outbred rodents which can lead to variable results. The current study evaluated the effects of adolescent social stress in male and female inbred (BALB/cJ) mice. Adolescent mice were exposed to repeat cycles of alternating social isolation and social novelty for 4 weeks...

Bening strictures of the esophagus are a frequently encountered problem in endoscopy. Dilation by Savary-Gilliard dilators or balloon dilators is the first line treatment and relieves dysphagia in about 75 % of cases. Complex strictures are at higher risk of treatment failure than simple ones and are considered as refractory after repetitive unsuccessful dilations. Adjunction of locally injected corticoids favors outcome in strictures of peptic origin. Further treatment options of refractory strictures are endoscopic incision therapy in short ones and temporary self expandable metallic (SEMS), plastic (SEPS) or biodegradable stent insertion in complex ones...

Hypertrophic pachymeningitis is an infrequent disorder. It can be idiopathic or secondary to infectious, autoimmune or neoplastic disease. The recently described 〈IgG4-related disease〉 could be the origin of many cases considered cryptogenic. We present the case of a 60-year-old man, with a history of headache and episcleritis in both eyes, with partial response to corticoid therapy. The brain MR study with gadolinium showed enhancement and thickening of the dura mater, extending from lateral wall of left temporal and occipital lobes to ipsilateral tentorium...

BACKGROUND: Granulosa cell tumor of the ovary is the most frequent sex cord stromal tumor and represents 2 to 5% of all primary ovarian cancers. Ovarian granulosa cell tumor is a malignant tumor with slow progression and in some cases this tumor is hormonally active. The recurrence of granulosa cell tumor often happens after 5 years. CASE PRESENTATION: We describe two cases of postmenopausal women with adult-type granulosa cell tumors of the ovary. Patient 1 is a 49-year-old European woman with a recurrent tumor; patient 2 is a 55-year-old European woman without recurrence of tumor...

In Duchenne muscular dystrophy (DMD), lack of dystrophin leads to progressive muscle degeneration, with DMD patients suffering from cardiorespiratory failure. Cell therapy is an alternative to life-long corticoid therapy. Satellite cells, the stem cells of skeletal muscles, do not completely compensate for the muscle damage in dystrophic muscles. Elevated levels of proinflammatory and profibrotic factors, such as metalloproteinase 9 (MMP-9), impair muscle regeneration, leading to extensive fibrosis and poor results with myoblast transplantation therapies...

Radiation-induced lung injuries mainly include the (acute or sub-acute) radiation pneumonitis, the lung fibrosis and the bronchiolitis obliterans organizing pneumonia (BOOP). The present review aims at describing the diagnostic process, the current physiopathological knowledge, and the available (non dosimetric) preventive and curative treatments. Radiation-induced lung injury is a diagnosis of exclusion, since clinical, radiological, or biological pathognomonic evidences do not exist. Investigations should necessarily include a thoracic high resolution CT-scan and lung function tests with a diffusing capacity of the lung for carbon monoxide...

The number of children and adult with congenital heart disease requiring implantation of cardiac pacemaker or cardioverter defibrillator is constantly increasing. The lead between stimulation/defibrillation site and the generator constitutes the main weakpoint of those devices despite the numerous recent technological advances: use of bipolar probes, corticoid elution electrodes, insulation improvement, magnetic resonance imaging (MRI) compatibility. Risk of device failure remains high in this population. Long term adverse events with endovascular devices remain high...

There is considerable interest in refining laboratory rodent environments to promote animal well-being, as well as research reproducibility. Few studies have evaluated the long term impact of enhancing rodent environments with resources and additional cagemates. To that end, male and female Sprague Dawley (SD) rats were housed singly (n = 8/sex), in pairs (n = 16/sex), or in groups of four (n = 16/sex) for five months. Single and paired rats were housed in standard cages with a nylon chew toy, while group-housed rats were kept in double-wide cages with two PVC shelters and a nylon chew toy and were provided with food enrichment three times weekly...

This is a case report of a rare isolated eosinophilic granuloma of vertebra L3, in a 15-year-old adolescent. Vertebral instability, due to aggravation of the osteolysis, occurred without neurological symptoms despite orthopedic treatment. Surgery was necessary to correct and stabilize the spinal deformation. Postoperative chemotherapy (vinblastine and corticoids) was given as recommended for Langerhans cell histiocytosis (HL2010). No recurrence was observed after 5 years of follow-up.

BACKGROUND: The current EAACI/GA(2)LEN/EDF/WAO guideline for urticaria provide specific recommendations for the diagnostic workup and treatment of patients with chronic spontaneous urticaria (CsU). This study explored if physicians in Ecuador know these recommendations and implement them in their actual clinical practice for CsU. METHODS: We investigated physicians who treat CsU patients in a cross-sectional study using a standardized questionnaire. Descriptive statistics were employed, adjusted logistic regression was performed to assess the link of guideline knowledge and use of therapy...
