Assessment of the Thyroid Functions among Female Flight Attendants

Introduction: Epidemiological observations indicate that stewardesses are exposed to reproductive and endocrine system disturbances. The aim of the study was to assess of thyroid function disturbances as well as to identify factors affecting the thyroid function among stewardesses working both within one time zone and on long-distance flights. Material and methods: The cross-sectional study covered 103 women aged 23–46. The study group (I) was divided into two subgroups: group Ia comprising stewardesses flying within one flight zone and group Ib stewardesses working on long-distance flights. The control group (II) were women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, BMI, menstrual cycle regularity, length of work, frequency of flying, thyroid stimulating hormone (TSH) concentration, level of free thyroxine (fT4), antibodies to thyroglobulin (aTG) and to thyroperoxidase (aTPO), prolactin concentration, sex hormone binding globulin (SHGB) concentration, total cholesterol, and low density lipoprotein (LDL) fraction. Descriptive methods and inferential statistics methods were used to compile the data. Results: The difference between the concentrations of TSH in the study group (2.59 mcIU/mL) and the control group (1.52 mcIU/mL) was statistically significant (p < 0.01). An elevated titer of thyroid antibodies (aTPO and/or aTG) was revealed in 46.3% of stewardesses and in 15.1% of patients from the control group (p < 0.001). Groups Ia and Ib in individual concentrations were not statistically significant. The frequency of occurrence of an elevated titer of thyroid antibodies depended on the length of work in the study group (p > 0.05). No statistically significant difference was found in patients spending up to 60 h a month flying and in patients spending more than 60 h flying, the percentage of the occurrence of thyroid antibodies was 50% and 43.5, respectively. Conclusions: The occurrence in stewardesses of a higher TSH concentration than in the control group can signify that stewardesses are burdened with a higher risk of the development of hypothyroidism in the future. The character of the work of stewardesses (frequency of flying as well as length of work) does not affect the immunological profile of the thyroid.

Work Affect

The work of flight attendants is associated with exposure to long-term stress, which may cause increased secretion of cortisol. The aim of the study is to determine the circadian rhythm of cortisol and to seek factors of potential influence on the secretion of cortisol in female flight attendants working within one time zone as well as on long-distance flights. The prospective study covers 103 women aged 23–46. The study group (I) was divided into two subgroups: group Ia, comprising female flight attendants flying within one flight zone, and group Ib, comprising female flight attendants working on long-distance flights. The control group (II) are women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, BMI, menstrual cycle regularity, the length of service, the frequency of flying, diurnal profile of the secretion of cortisol, testosterone, estradiol, 17-OH progesterone, SHBG, androstenedione, and progesterone concentration. Descriptive methods and inferential statistics methods were used to compile the data. Comparing the profile of flight attendants from groups Ia and Ib shows that the curve flattened among women flying within one time zone. The secretion curve is also more flattened in women with less years worked and in flight attendants working less than 60 h per month. Due to the character of work, the female flights attendants do not have hypersecretion of cortisol. Frequency of flying and length of work affect the dysregulation of HPA axis.

Sepsis And Septic Shock

Abstract Background Challenges of diagnosing and treating sepsis only seem more difficult as incidence increases, patients become older and sicker, and pathogenic organisms evolve. New understanding of inflammatory mediators and pathways, immunity, and genetic variability in this disease state suggests that the current definitions of SIRS, sepsis, severe sepsis, and septic shock are oversimplified. Objective The aim of our study is to evaluate the level of RDW, CRP and clinical scores "SOFA and APACHI" as markers in patients with sepsis and their levels on the outcome and resolution of sepsis in ICU. Methodology We conducted a prospective observational controlled study on 90 adult persons of both sex, 45 of them are adult patients and served as the study group (Group I), and the other 45 are healthy adult volunteers and served as the control group (Group II). The study group represented patients admitted to the ICU of Intensive Care Unit at Damanhour Medical National Institute who fulfilled the diagnostic criteria for sepsis, severe sepsis and septic shock on arrival to ICU according to the SCCM/ ESICM/ ACCP/ ATS/SIS International Sepsis Definitions Conference. Results. In the present study we found that CRP measured on admission was not a predictor of mortality, while that measured at day 5 and day 10 predicted mortality, where there was no statistically significant difference in CRP levels between survivors and non-survivors at the day of admission while there were statistically significant differences between survivors and non survivors according to CRP levels at day 5 (p = 0.001*) and at day 10 (p = 0.001*). It was found also that there were statistically significant differences between survivors and non-survivors according to RDW at day 1(p = 0.011*) and at day 5(p = 0.009*), at day 10 was found there was no statistically significant difference between survivors and non-survivors (p = 0.338). Conclusion RDW is a new promising cheap and readily available biomarker that can be able to diagnose patients with sepsis with accuracy comparable to CRP. Also, RDW at admission is able to predict mortality.

Background: the aim was to study the prevalence of abnormal thyroid function and thyroid autoimmunity in infertile women and in general population (control group) and to correlate the thyroid dysfunction with presence of anti-thyroid antibodies. It was a case control study. The study was carried out at Department of obstetrics and gynaecology, Kasturba Hospital, Delhi. Population of the study was fifty infertile women in whom other causes of infertility are excluded and fifty fertile women attending out- patient department with other complaints.Methods: All the women enrolled in the study were non pregnant, clinically euthyroid (with no signs and symptoms of thyroid disorders and no documented abnormal thyroid function test) and no known autoimmune disorder. Detailed history and a thorough general physical examination, including thyroid examination was done. Haemogram, blood group, fasting and post prandial blood sugar, VDRL, transabdominal ultrasound, TSH, free T3, free T4, and antithyroid per-oxidase antibody assay was done using the ELISA technique.Results: The mean age of the study group was found 28.38±2.45 years, 22% had abnormal thyroid function, 20% had antithyroid antibodies positive and the mean TSH of the study group was 4.61±1.72µIU/ml. The mean age of the control group was found to be 29.10±2.01 years, 12% had abnormal thyroid function, 10% had antithyroid antibodies positive and the mean TSH of the control group was 3.89±1.56µIU/ml.Conclusions: Thyroid dysfunction and anti-thyroid antibodies were more prevalent in patients with infertility. A statistically significant correlation was established between thyroid autoimmunity and thyroid dysfunction in infertile women in the study.

Brainstem Response

Abstract Background Migraine is a neurological disease associated with abnormal excitability in visual, somatosensory and motor cortex. Previous researches reported abnormalities in the auditory brainstem response (ABR) and in vestibular functions. These results are an indicator of impending auditory malfunction in Migraine and disruption of central auditory processing mechanisms. Objectives This study aimed to assess and compare central auditory processing (CAP) performance in migraine patients with and without dizziness and healthy controls. Subjects and method Sixty subjects aged between18 and 60 years divided into 3 groups; control group (twenty normal healthy subjects), study group I (twenty subject diagnosed with migraine) and study group II (twenty subjects diagnosed with vestibular migraine). They were subjected to a headache sheet, central auditory processing questionnaire and Psychophysical central auditory tests: including Arabic Speech Intelligibility In Noise (SPIN) test for adults, Arabic Dichotic digit test, Gap In Noise (GIN) test, Duration pattern test and Arabic memory tests. Results Statistically significant difference was found between the 2 study groups and control group regarding right dichotic (p = 0.004),right and left duration pattern tests (p = 0.01) with highly statistically significant difference(p < 0.001) Gap In Noise (GIN) test, left dichotic digit test, right and left speech in noise. But there was no statistically significant difference between the two study groups regarding all tests. Conclusions Patients with migraine and vestibular migraine had poor performance in all central auditory tests when compared with control this mean that migraine lead to impaired central auditory processing in adults. Also, there was no significant difference between the 2 study groups regarding central auditory test results which may support that both migraine with and without dizziness have the same pathophysiology.

The aim of this in-vivo study was to evaluate/compare the clinical periodontal parameters in patients with true combined endo-perio lesions (EPL), treated with gutta-percha (GP) and mineral trioxide (MTA) as an obturation material alone and with addition of bone grafting in such lesions. 120 Saudi patients (mean age = 41yrs) diagnosed with true combined EPL participated in this study. Group I (control group, n = 30) was treated with conventional endodontic treatment using GP for obturation. Group II (n = 30) was treated with conventional endodontic treatment using MTA for obturation. Group III (n = 30) was treated with conventional endodontic treatment using GP for obturation + grafting procedure to fill the bony defect. Group IV (n = 30) was treated with conventional endodontic treatment using MTA for obturation + grafting procedure to fill the bony defect. Clinical parameters (Pocket depth (PD); Clinical attachment loss (CAL); keratinized tissue width (KTW); gingival phenotype (G.Ph.) and Cone Beam Computed Tomography Periapical Index (CBCTPAI)) were recorded and compared at baseline, 3, 6, 12 months’ interval. For the groups III and IV, CBCTPAI showed significant difference (p < 0.0001) with the other groups at 6 months and 1-year interval. The group with MTA + bone graft showed 76% and 90% patients with 0 score at 6 months and 1-year follow-up, respectively. Comparison of mean values of PD among study groups at 3 months, 6 months and 1 year showed significant difference at 3 months, whereas the mean PD values of subjects in GP + bone graft showed significantly higher PD values than other 3 groups (p = 0.025). Use of GP and MTA for root canal obturation along with periodontal therapy and bone augmentation helps in resolving complex endo-perio lesions. Bone grafting in addition to obturation with MTA was found to be the best treatment strategy in management of EPL cases and is recommended for clinicians who are treating EPL patients.

Abstract Introduction Good hearing in pilots, including central auditory skills, is critical for flight safety and the prevention of aircraft accidents. Pure tone audiometry alone may not be enough to assess hearing in the members of this population who, in addition to high noise levels, routinely face speech recognition tasks in non-ideal conditions. Objective To characterize the frequency-following response (FFR) of a group of military pilots compared with a control group. Methods Twenty military pilots in the Study Group and 20 non-pilot military personnel, not exposed to noise in their work, in the Control Group, all with normal hearing, aged between 30 and 40 years old, completed a questionnaire to assess their hearing habits, and their FFRs were measured with a /da/ syllable (duration 40 milliseconds, speed 10.9/s), at 80 dB NA in the right ear. All procedures were approved by the ethical committee of the institution. Statistical analysis was performed using the t-Student or Mann-Whitney tests for quantitative variables, and the Fisher or chi-squared tests for qualitative variables, and a value of p < 0.05 was considered to be statistically significant. Results There was no significant difference between the groups regarding auditory habits. In the FFR, wave amplitudes A (p = 0.01) and C (p = 0.04) were significantly lower in the Study Group. Conclusion Working as a military pilot can be a crucial factor in determining an individual's typical FFR pattern, demonstrated in the present study by statistically significant reductions in the amplitudes of the A and C waves.

AbstractFracture resistance of endodontically treated teeth restored with post. Aims: This study aims to compare the fracture resistance of endodontically treated teeth restored with resin fiber and stainless steel post. Commercially available prefabricated resin fiber post(Dentsply Maillefer Easy Post), prefabricated stainless steel post(Coltene/Whaledent Parapost) were used. Methods and Material: Forty five maxillary central incisors were obturated and divided into 3 groups: Control Group (Group I) without any post (n = 15), Resin Fiber Post Group (Group II) (n = 15) and Stainless Steel Post Group (Group III) (n = 15). In all Groups except control group, post space was prepared; a post was cemented, and a core build-up was provided. All the specimens were subjected to compressive force under a universal testing machine until fracture. Statistical analysis used: The results were analyzed using the variable analysis test (ANOVA). Results: One-way analysis of variance revealed significant difference among test groups. The control group demonstrated highest fracture resistance (925.2183 N), followed by the resin fiber post group (486.7265 N) and stainless steel post group (423.539N). Conclusions: Teeth restored with resin fiber post showed higher fracture resistance values than prefabricated stainless steel post.
