Allergic rhinitis is a common problem increasing greatly over the past three decades. Several studies have found a possible link between dyslipidemia and allergic disease but the relating causal mechanisms remain elusive. The aim of this study is to investigate the association between blood lipid levels and the presence of allergic rhinitis. A multicentre prospective study was carried out on 160 allergic rhinitis patients and 160 volunteers as a control according to age, gender, body mass index (BMI) values and full blood lipid profile. A possible correlation between abnormal dyslipidemia parameters and the severity of allergic rhinitis was studied too. Demographic characteristics didn’t differ between groups. While levels of LDL-C, total cholesterol, as well as TC/HDL ratio and LDL/HDL ratio, were significantly higher (p<0.001) in patients with allergic rhinitis, there was a positive correlation between abnormal dyslipidemia parameters and moderate/severe allergic rhinitis symptomatology ( p<0.001). We support the hypothesis that dyslipidemia might play a role in in the manifestation of allergic rhinitis.
The hyoid bone is the only "suspended bone" in our body, and its suspension system has an important role in posture maintenance. We studied postural modification in a group of patients affected by Obstructive Sleep Apnea Syndromewho had undergone surgical treatment including hyoid suspension. The surgical procedure performed was section of supra- and infrahyoid muscle and mobilization of the hyoid bone through its suspension to the thyroid cartilage. We studied the postural changes with stabilometric tests. In the early post-operative (one week) follow-up, we performed a posturography test with closed eyes and occlusal disjunction, and saw a worsening of the average parameter of the centre of pressure with antero-posterior oscillations. However, we would like to highlight that by the time of the one year follow up, a compensatory mechanism had been established which allowed for a return to normal hyoid bone kinematics.
The aim of the study was to evaluate individual inflammatory response after inguinal hernioplasty by measuring baseline and post-operative serum IL-6 response to surgery and quantifying the variability of the serum response in a homogeneous group of patients.Patients enrolled in the study underwent inguinal hernioplasty. Blood samples were used to analyze serum IL-6, TNF-alpha, LOOH and GSH levels. To identify high and low IL-6 responders, patients were divided into 2 groups according median values of the peak levels of IL-6. Mean levels of the cytokine were comparable at baseline but reached peak at 6 h and persisted elevated at following hours among high responders whereas remained significantly lower over time among low responders.Patients identified as low responders showed not significant changes in serum IL-6 levels over the post-operative period. In contrast, high responders demonstrated a significant response reaching the peak level of IL-6 after 6 hours post operation.
The objective of this paper is to respond to the urgent need for an increase in access to HIV care among adolescents and young people in Sub-Saharan Africa. Since 2014, doctors with Africa CUAMM in collaboration with UNICEF have been supporting specific ambulatories for the youth population (between the ages of 10- 24) aiming to improve health education, specifically in relation to HIV prevention. Mozambique has the eighth highest prevalence of HIV in the world. It represents one of the six countries in which half of the adolescents living with HIV reside. Beira is Mozambique’s second largest city, and in 2009 it had the most women and men between the ages of 15-49 were living with HIV. This study retrospectively analyzes data collected between 2013 and 2014, which described the impact of a new health service in a low resource setting with high HIV prevalence. The specificity of the service, only dedicated to young people, is the basis for this paper. We observed a significant increase in counseling in 2014 compared to 2013 (102,533 vs 63,959, p<0.01), confirming that strengthening specific youth services is an effective intervention for improving access to care of this target population. Youth ambulatories are great instruments to improve access to HIV care among young people.
Cerebral cavernous malformations (CCMs) are benign tumours that affect brain capillaries. Although many cases remain asymptomatic, their incidence is steadily increasing. CCMs can arise sporadically or be inherited as autosomal dominant character. Inherited forms result from mutations at three different loci CCM1/KRIT1, CCM2/MGC4607 and CCM3/PDCD10. Etiology of sporadic forms is still unclear. Among the various molecular mechanisms proposed, presence of somatic mutations was sometimes proven. Here we report results obtained by a molecular screening of the three CCMs genes, performed on both germ-line and somatic DNA, isolated from CCM endothelial cells, in eight patients affected by sporadic lesions, who undergone surgery. Comparison of germ-line and somatic sequencing data, for each patient, showed no differences. Our results confirm that presence of somatic mutations is not sufficient to explain CCMs onset in patients affected by sporadic forms and with no CCM genes germ-line mutations. Other possible pathogenic mechanisms are also discussed.
Rheumatoid Retinitis pigmentosa (RP) is the most common inherited retinal dystrophy affecting peripheral visual field and usually culminates in complete blindness. Among mutations in 73 genes implicated in RP pathogenesis, those in RP1 gene are inherited in autosomal recessive or dominant fashion. In RP Sicilian patients, we detected 3 polymorphisms in RP1 exon 4 hotspot region, not known to be associated with RP disease. Here, their frequency in Sicilian populations was assayed in order to detect possible association with RP. Samples from 220 unrelated healthy donors born and living in Sicily for at least two generations and 50 RP patients from Messina were screened. Frequencies of all three polymorphisms in RP patients from Messina were about twice those observed in the healthy controls from the same town and the overall Sicilian population. An association between 3 polymorphisms and RP was suggested, although their role in other related disorders cannot be excluded.
The demographic and epidemiological transitions resulted in a pressing need to reformulate the health workforce demand and to revise pre- and post-graduate training to prepare the medical profiles to meet the new health needs focused on chronic diseases. The Italian Junior Doctors Association and the Giotto Movement carried out a web survey to identify the motivational aspects and the level of satisfaction of Italian junior doctors regarding knowledge and skills acquired after attending the General Practitioners’ specific training (GP-ST). Three-hundred-forty-seven General Practitioners (GPs), 302 trainees and 45 newly qualified trainees answered a web questionnaire. Significant differences (p-value= 0.018) were documented between the two groups regarding the level of satisfaction on the GP-ST. The analysis by geographic macro-areas of the answers given by the 302 trainees showed a heterogeneous level of overall satisfaction (p-value= 0.005). In conclusion, the evidence provided by this cross-sectional study support the proposal to evolve the GP-ST regional courses into general practice and primary care specialization schools.
Human immunodeficiency virus (HIV) causes a sexually transmitted disease (STD) affecting the human immune system. It is mainly transmitted through sexual intercourse, blood transfusions, hypodermic needles, and parenterally. Multiple actions can be taken to prevent the spread of HIV/AIDS, such as condom and sterile needle use and HIV testing for pregnant women. This study aims to assess freshmen students’ awareness, knowledge, attitudes, and behavioral perceptions regarding HIV/AIDS at Oakland University (OU) in Michigan. This study is a cross-sectional survey targeting freshman students at OU. The questionnaire is comprised of seven sections including demographics, risk perception, protection measures alcohol tendencies, health-seeking behaviors, culturally sensitive issues, and methods of dissemination of information. The mean age of respondents was 20. The majority of respondents knew that HIV is transmitted sexually (98%) and by sharing needles (98%). Many misconceptions about transmission of HIV were expressed by 53%. Data showed that while there was good knowledge regarding HIV transmission and prevention, some misconceptions still prevailed. Our results indicate the need to develop educational programs with specific interventions to raise awareness about preventive measures, clear misconceptions, and promote healthy lifestyle in order to prevent new HIV infections among young college students.
Rheumatoid arthritis (RA) is an inflammatory joint disorder whose progression leads to destruction of cartilage and bone. Chemokines, molecules able to induce chemotaxis in inflammation, are involved in RA pathogenesis. Aim of this study was to determine whether -2150 A>G and delta32 (Δ32) polymorphisms in the chemokine receptor 5 (CCR5) confer susceptibility to rheumatoid arthritis. Polymorphisms were assessed in 70 seropositive RA patients and 200 healthy individuals of Messina and province. About -2150 A>G polymorphism, a significant increase in AG genotype frequency was observed in controls than in patients, despite a not significant difference in allelic frequencies. Conversely, allelic and genotypic frequencies related to Δ32 polymorphism were significantly higher in controls group than in patients. Furthermore, in the patient group no individuals with Δ32/Δ32 genotype were found. These results suggest that CCR5 polymorphisms seem to play an important role in susceptibility to RA exerting a protective role in the disease.
Positive airway pressure is the treatment of choice among obstructive sleep apnea syndrome patients. Among surgical options, multilevel approach is a good option in patients with an involvement of all tract of first airway. The aim of the present work is to establish the efficacy of anterior palatoplasty in the treatment of selected patients with mild obstructive sleep apnea syndrome or simple snoring, within a multilevel surgery. The group was composed of 16 mild obstructive sleep apnea syndrome adult patients collected from January 2015 to June 2016 at University of Palermo, Ear, Nose and Throat Department. To make diagnosis of obstructive sleep apnea syndrome, we employed polysomnography, the Epworth Sleepiness Scale and an endoscopic study of aerodigestive tract in order to identify the sites of collapse. All patients underwent to inferior turbinate reduction, anterior pharyngoplasty and hyoid suspension. After treatment, 11 patients had Apnea Hypopnea Index ≤5 and 4 patients less than 50% compared to the starting one. According to Epworth Sleepiness Scale, the daytime sleepiness enhanced from 12.6 to 8.6 post-operative average. Pre-operative mean value of Muller’s maneuver was N (nose):2.6, O (oropharinx):3.4, H (hypopharinx):2.5 Before performing surgical procedure each patient was subjected to sleep endoscopy to evaluate better the pattern of collapse. The post-operative mean outcomes of Mueller’s Maneuver was: N 1.5, O 1.3, H 1.3. Barbed Anterior pharyngoplasty, combined with other surgical procedures, can be considered a valid surgical option to relieve snoring, and mild apnoic events. Our preliminary results, show that the anterior palatoplasty, combined with other surgical procedures, can be considered a valid surgical option to relieve snoring and mild apnoic events.
