Latent Tuberculosis Infections in Different Intensity of Exposure within Moroccan Population: Influence of Age and Bacille Calmette-Guérin Vaccination.

Background: In Morocco, latent tuberculosis infection (LTBI) is a public health concern affected by the country's location as transit area between sub-Saharan Africa with high TB burden to Europe. This study aimed to assess the influence of exposure intensity to Mycobacterium tuberculosis (Mtb), age, and Bacille Calmette-Guérin (BCG) vaccination on LTBI prevalence in Morocco.

Methods: A cross-sectional study of 131 participants, including 98 non-exposed healthy volunteers (NEHV) and 33 healthcare workers exposed to active TB (exposed healthcare workers [EHCW]), was conducted.

Management of double carotid blowout with definitive repair after temporizing stent graft placement.

Carotid blowout syndrome is a life-threatening complication for patients with head and neck cancer. Temporizing stent graft procedures improve short-term survival and can be the definitive treatment for various reasons, including a poor oncologic prognosis, unsuitability for definitive reconstruction, or a lack of operative options. A second carotid blowout will often be fatal.

The Effects of Insomnia and Sleep Loss on Cardiovascular Disease.

Sleep loss has negative impacts on quality of life, mood, cognitive function and heath. Insomnia or difficulty sleeping is also a prevalent issue, affecting up to 35% of the population at some point in their lives. Insomnia is linked to poor mood, increased use of health care resources, and decreased quality of life as well as possible links to cardiovascular risk factors and disease.

CD1 gene polymorphism and susceptibility to celiac disease: Association of CD1E*02/02 in Moroccans.

CD1 glycoproteins are a class of antigen presenting molecules that bind and present non-peptidic antigens (lipids and glycolipids) for immune recognition. CD1 polymorphisms, although limited, could have a critical role in antimicrobial, anticancer, and autoimmune responses and disease susceptibility. Ethnic differences and interactions between genetic and environmental factors make it attractive the study of these molecules in autoimmune inflammatory disorders, such as celiac disease (CD), in which a strong genetic predisposition (HLA-DQ2/DQ8) and pressure of environmental factors have a central role.

Chronic Opioid Use after Laryngeal Cancer Treatment: A VA Study.

Setting: A single Veterans Health Administration site.

Moroccan lymphocyte subsets reference ranges: age, gender, ethnicity, and socio-economic factors dependent differences.

Lymphocyte subsets reference ranges are helpful for a precise diagnosis and therapy of various diseases. We attempted in the current study to establish Moroccan lymphocyte reference range and reveal age, gender, ethnicity, income, and instructional levels dependent differences. Lymphocyte subsets percentage and absolute count were determined by 4-color flow cytometry in a population study of 145 adults Moroccan healthy volunteers.

Proteomics characterization of CENP-B epitope in Moroccan scleroderma patients with anti-centromere autoantibodies.

Background: Anti-centromere auto-antibodies (ACA) have been described as a marker in Systemic sclerosis (SSc) disease. CENP-B is the major centromere auto-antigen recognized by SSc patients with positive ACA. Our aim was to characterize the major epitope involved in the anti-CENP-B immune response of Moroccan SSc patients.

Efficacy of Voice Therapy in Improving Vocal Function in Adults Irradiated for Laryngeal Cancers: A Pilot Study.

Background: Radiation therapy (XRT) for laryngeal cancers causes acute and chronic vocal dysfunction. Although these deleterious effects of XRT are well-established, there is a dearth of research with respect to effective voice rehabilitation following XRT for laryngeal cancers.

Objective: To obtain preliminary data on the efficacy of voice rehabilitation, using vocal function exercises (VFEs) in improving vocal function in adults irradiated for laryngeal cancer.

Immune activation and regulatory T cells in Mycobacterium tuberculosis infected lymph nodes.

Background: Lymph node tuberculosis (LNTB) is the most frequent extrapulmonary form of tuberculosis (TB). Studies of human tuberculosis at sites of disease are limited. LNTB provides a unique opportunity to compare local in situ and peripheral blood immune response in active Mycobacterium tuberculosis (Mtb) disease.

Immunological and Clinical Characteristics of Systemic Lupus Erythematosus: A Series from Morocco.

Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease with a high female predominance. To date, studies about SLE in Morocco are few. This retrospective study describes the clinical and immunological features in a series of 50 SLE Moroccan patients in University Hospital Center of Rabat, Morocco, between December 2011 and December 2013.

Awake vs Sedated Tracheostomies: A Review and Comparison at a Single Institution.

Objective: The literature surrounding awake tracheostomies is sparse, particularly comparing awake tracheostomy patients to that of the sedated tracheostomy population. This study sought to compare tracheostomy patient demographics, indications, and outcomes of the 2 populations.

Study Design: Case series with chart review.

Elevated International Normalized Ratio Is Not Associated With Increased Perioperative Morbidity in Podiatric Limb Salvage Surgery: A Retrospective Analysis.

The risk of hemorrhage always exists in anticoagulated patients with an elevated international normalized ratio (INR), a risk that must be measured against the necessity for surgical procedures. The objective of the present retrospective medical record study was to assess the safety with which limb salvage procedures can be conducted in patients with an INR >1.4.

New variant identified in major susceptibility locus to tuberculosis on chromosomal region 8q12-q13 in Moroccan population: a case control study.

Background: Tuberculosis (TB) remains a global health problem. Several studies have implicated genetic host factors in predisposing populations to TB disease. In this study, we have selected NSMAF (Neutral Sphingomyelinase Activation Associated Factor) as a candidate gene to evaluate its level of association with TB disease in a Moroccan population for two reasons: first, this gene is located in a major susceptibility locus on chromosomal region 8q12-q13 in the Moroccan population, closely linked to the CYP7A1 gene, which was previously shown to be associated with TB disease; second, NSMAF has an important role in immune system function.

Ceruminous Adenoid Cystic Carcinoma of External Auditory Canal.

An adenoid cystic carcinoma (AdCC) of the ceruminous glands is very rare; its diagnosis is most often challenging, and simple biopsies may be misleading. Our paper describes a case of a circumferential mass of the left ear canal that was initially reported as a basal cell carcinoma on biopsies in the clinic and on frozen sections intraoperatively. The final pathology was an AdCC of the ceruminous glands of the external auditory canal.

Otolaryngology consultation tracheostomies and complex patient population.

Purpose: To assess for the differences in patients undergoing tracheostomy by the otolaryngology consult service versus other specialties.

Materials And Methods: A series of 1035 tracheostomies performed at our institution from January 2013 through November 2015 was retrospectively reviewed. Patient-related factors that contribute to procedural difficulty were reviewed.

Outpatient versus observation/inpatient parotidectomy: patient factors and perioperative complications.

The objective of this manuscript is to review a single institution's experience with superficial or total parotidectomy in outpatient and observation/inpatient groups. All patients who underwent superficial or total parotidectomy between 2009 and 2015 were identified. Patients were excluded if they had undergone concurrent surgery such as neck dissection, had prior radiation treatment or surgery at the operative site.

The Effects of Insomnia and Sleep Loss on Cardiovascular Disease.

Sleep loss has negative impacts on quality of life, mood, cognitive function, and heath. Insomnia is linked to poor mood, increased use of health care resources, decreased quality of life, and possibly cardiovascular risk factors and disease. Studies have shown increase in cortisol levels, decreased immunity, and increased markers of sympathetic activity in sleep-deprived healthy subjects and those with chronic insomnia.

Correlation of Positron Emission Tomography/Computed Tomography Scan with Smoking, Tumor Size, Stage and Differentiation in Head and Neck Cancer Patients.

The goal of this study was to identify associations between positron emission tomography/computed tomography (PET/CT) maximum standardized uptake value (SUVmax) in patients presenting with head and neck squamous cell carcinoma (SCC) with tumor site, size, histologic differentiation, smoking, and diabetes. Charts of patients with oropharyngeal and laryngeal SCC who underwent F-fluorodeoxyglucose PET/CT scans were reviewed between May 2007 and August 2013. Statistical analyses included modeling log-transformed SUVmax values by tumor site, size, histologic differentiation, smoking status, and diabetes using unadjusted linear regressions.

CD1A, D and E gene polymorphisms in a North African population from Morocco.

CD1 molecules are specialized in capturing and presenting lipids and glycolipids to distinct subsets of T and NKT cells. Glycolipid presentation could play a significant role in the immune response against microbial infections. There are five closely linked CD1 genes in humans, named CD1A, B, C, D, and E, which all show a limited polymorphism.
