Complicated airway management in a child with prune-belly syndrome

We describe a 15-month-old boy with prune-belly syndrome (PBS) in whom airway management was complicated. Following an inhalation induction using sevoflurane, tracheal intubation by direct laryngoscopy proved impossible after repeated attempts. A laryngeal mask airway (LMAtrade mark) was inserted and the child had an uneventful anaesthetic course.     

Effects of lidocaine and prednisolone on endoscopic rigid laryngoscopy

Objective/Hypothesis: The aim of this study is to compare the effects of lidocaine and methylprednisolone on postoperative respiratory complications caused by short‐term laryngeal surgery by way of rigid laryngoscope under general anesthesia. The effects of these drugs on recovery from anesthesia are also compared. Study Design: One hundred American Society of Anesthesiologists physical status I to II patients over 20 years of age admitted for laryngeal mass, nodule, or polyp were included in this prospective, placebo‐controlled, randomized, and double‐blinded study. Methods: Patients were randomly allocated to four groups; methylprednisolone 3 mg.kg⁻¹ (group 1), 0.9% saline physiologic 5 mL (group 2), lidocaine 1.5 mg.kg⁻¹ (group 3) intravenously, seven puffs of lidocaine aerosol 10% to oropharyngolaryngeal structures topically (group 4) sprayed. Anesthesia recovery time was calculated. Respiratory system was evaluated using a scoring table during early postoperative period. Results: Ninety‐two cases were suitable for analysis. Recovery time was longer in group 1 (9.8 3± 3.79 minutes) than in groups 3 and 4 (7.22 ± 2.38, 7.50 ± 2.30 minutes, respectively) (P < .05). Postoperative respiratory complications were lower in groups 3 and 4 than group 2 (P < .05). Conclusions: Lidocaine intravenous or topical administration was effective in reducing postoperative respiratory complications after short‐term laryngeal surgery by way of rigid laryngoscope. Methylprednisolone prolonged recovery time from anesthesia.     

Gender diversity in chiropractic leadership: a cross-sectional study

BackgroundThe purpose of this cross-sectional study was to compare the number of males and females in leadership positions, and whether there is a relationship between gender and degrees held in those positions, within chiropractic academic institutions, national regulatory bodies and the most widely representative national professional associations in the United States and Canada.MethodsPublicly accessible websites from chiropractic institutions and organizations were used to collect data. Pearson χ² tests of independence were conducted to determine the relationship between gender (male vs. female) and other variables, including position (principal vs secondary), and chiropractic and other advanced professional degrees.ResultsA total of 107 leaders were identified across institutions and organizations. Under one-third of leaders (30.8%) were identified as female. Males were more likely to be in principal leadership roles (86.2%) and more likely to be in a secondary leadership position (62.8%).ConclusionMale leaders significantly outnumber female leaders in both principal and secondary leadership positions within American and Canadian chiropractic institutions. Strategies should be developed to include gender diversity within all chiropractic organizations.

Is there a role for kisspeptin in pathogenesis of polycystic ovary syndrome?

Aim: To investigate association of kisspeptin levels in infertile women with different ovarian reserve patterns.

Materials and methods: In this prospective cross-sectional study, 157 participants were recruited. The women were divided into three groups: (i) adequate ovarian reserve (AOR) (n?=?57), (ii) high ovarian reserve (PCOS) (n?=?60), (iii) diminished ovarian reserve (DOR) (n?=?40). Weight, height, waist circumference (WC), hip circumference (HC), body mass index (BMI), waist/hip ratio (WHR) were measured. The blood samples were analyzed for estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), 17-hydroxy progesterone (17OHP), dehydroepiandrosterone sulfate (DHEAS), antimullerian hormone (AMH), kisspeptin measurements.

Results: FSH concentration was higher and AMH concentration was lower in DOR group (p?p?p?=?.001, p?p?=?.003, respectively). The 17OHP level did not differ among the groups (p?=?.15). Women with PCOS possessed the highest kisspeptin level (p?=?.01). The kisspeptin level was negatively correlated with FSH level (r?=??0.18, p?=?.02) and positively correlated with TT and DHEAS levels (r?=?0.17, p?=?.02 and r?=?0.23, p?=?.003, respectively).

Conclusions: Women with PCOS had increased serum kisspeptin levels. Kisspeptin concentrations were negatively correlated with serum FSH and positively correlated with serum TT and DHEAS levels.     

L-glutamic acid-g-poly hydroxyethyl methacrylate nanoparticles: acute and sub-acute toxicity and biodistribution potential in mice

The aim of this safety study in mice was to determine in vivo toxicity and biodistribution potential of a single and multiple doses of L-glutamic acid-g-p(HEMA) polymeric nanoparticles as a drug delivery system. The single dose did not cause any lethal effect, and its acute oral LD₅₀ was >2.000 mg/kg body weight (bw). Multiple doses (25, 50, or 100 mg/kg bw) given over 28 days resulted in no significant differences in body and relative organ weights compared to control. These results are supported by biochemical and histological findings. Moreover, nanoparticle exposure did not result in statistically significant differences in micronucleus counts in bone marrow cells compared to control. Nanoparticle distribution was time-dependent, and they reached the organs and even bone marrow by hour 6, as established by ex vivo imaging with the IVIS^® spectrum imaging system. In conclusion, L-glutamic acid-g-p(HEMA) polymeric nanoparticles appear biocompatible and have a potential use as a drug delivery system.KEY WORDS: biocompatibility, blood biochemistry, genotoxicity, histology, in vivo toxicity, micronucleus test, polymers     

Behavioural effects of chronic exposure to sub-anesthetic concentrations of halothane, sevoflurane and desflurane in rats

BACKGROUND: A double-blind, randomized trial was conducted to determine the behavioural effects of chronic exposure to subanesthetic concentrations of halothane, sevoflurane and desflurane in rats. METHODS: Halothane, sevoflurane and desflurane group rats received 0.1%, 0.3%, and 0.6% concentrations in a flow rate of 3 L.min(-1) O(2) respectively. Control animals also received 3 L.min(-1) O(2) in another investigation room, which had the same properties as the study group rooms. Rats breathed inhaled agents or oxygen between 09:00-13:00 hr every day for 30 days. After 30 days of inhalation of subanesthetic doses of inhaled agents or oxygen, behavioural tests were applied. RESULTS: Tests of exploratory activity and curiosity (hole-board test), anxiety (elevated plus maze test) and learning and memory functions (multiple T maze test), demonstrated that chronic exposure to subanesthetic concentrations of all three anesthetics alters behavioural functions in rats. However, impairment of learning (P<0.05) and memory function (P<0.05) were greater in association with desflurane, in comparison to halothane and sevoflurane-treated rats. CONCLUSION: Chronic exposure to subanesthetic concentrations of halothane, sevoflurane and desflurane is associated with behavioural change in rats. Of the three drugs, desflurane was associated with the lowest learning and memory function test scores.     

Effects of Creating Awareness Through Photographs and Posters on Skin Self-Examination in Nursing Students

Nurses can have an influence on primary and secondary prevention of skin cancer. Therefore, it is important to help them acquire knowledge and skills necessary to modify behavior in relation to skin cancers. The aim of this study was to examine effects of creating awareness through photographs and posters on knowledge and skills of skin self-examination in nursing students. The study had a quasi-experimental design with a pretest and a posttest in a single group. The study population included 249 last-year nursing students in Turkey. Non-probability sampling was used to reach the population. The study sample was composed of 201 students volunteering to participate in the study, and the response rate was 81 %. Of the students, 85.1 % (n?=?171) were female and the mean age of the students was 22.18?±?0.78 years. Of the students, 94.5 % did not know the asymmetry, border, color, diameter, evolution (ABCDE) criteria on the pretest, but this rate decreased to 20.9 % on the posttest. The mean score for knowledge of symptoms of skin cancer was 10.95?±?1.37 on the pretest and 11.48?±?0.90 on the posttest. There was a significant linear increase in the scores for knowledge of the symptoms (F?=?7.874, p?<?0.001) after the intervention with photographs and posters. The students were observed to learn the ABCDE criteria and had increased knowledge of skin cancer symptoms after the intervention using photographs and posters. Photographs and posters are effective tools which can be used to increase awareness of skin self-examination.
