Authors: Abd-Elsattar Aliaa A. , Amin Mona M. , Elbarody Nadia H. , Abaza Ragaa H.
Published: March 2024

Background:

Alfacalcidol is a vitamin D analog mainly used in the management of osteoporosis. Apart from the well-known role of vitamin D in bone and calcium metabolism, an immune-modulator role of vitamin D in allergic diseases was suggested. Aim: To evaluate the potential effect of alfacalcidol either alone or in combination with salbutamol or/and prednisolone and its role in the protection and management of experimentally induced allergic asthma.

Materials and methods:

Male guinea pigs were divided into two groups: group A constituted normal guinea pigs (received saline) and group B constituted ovalbumin-sensitized guinea pigs, which were divided into eight subgroups: group B1 (control): groups from B2 to B4 was treated with salbutamol, prednisolone, alfacalcidol, respectively, for 1 week, while group B5 was treated with salbutamol+prednisolone; group B6 was treated with salbutamol+alfacalcidol; group B7 was treated with prednisolone+alfacalcidol; and group B8 was treated with salbutamol, prednisolone, and alfacalcidol for 1 week. Twenty-four hours after the last dose, the animals were subjected to both: (a)pharmacological studies, (b) histopathological studies (group A, group B1, B3, and B4).

Results:

(a) Pharmacological studies: sensitization of guinea pigs caused a significant increase in amplitude of histamine-induced contractions of isolated tracheal smooth muscles in comparison to that of the normal one. Treatment of sensitized guinea pigs with salbutamol, prednisolone, or alfacalcidol produced a significant reduction in the amplitude of histamine-induced contractions in comparison to sensitized nontreated guinea pigs. Addition of alfacalcidol to salbutamol or prednisolone in the treatment of sensitized guinea pigs caused more decrease in the amplitude of histamine-induced contractions. However, the highest reduction in the amplitude of contractions of isolated tracheal strips was produced by the treatment of guinea pigs with a combination of salbutamol, prednisolone, and alfacalcidol. (b) Histopathological examinations: treatment of sensitized guinea pigs with alfacalcidol resulted in an anti-remodeling effect, while prednisolone showed better anti-inflammatory effect, when it was compared with that of the control group.

Conclusion:

Alfacalcidol was shown to possess anti-inflammatory and anti-remodeling effects in allergic asthma. It was superior to prednisolone regarding the anti-remodeling effect. So, alfacalcidol could be beneficial in the management of allergic asthma.
Intravenous dexmedetomidine enhances the experience of visceral pain in parturients during cesarean delivery under spinal anesthesia
Authors: Elsawy Ahmed G.
Published: March 2024

Background and hypothesis

Visceral pain is a common incidence in cesarean delivery under spinal anesthesia. Dexmedetomidine (DEX) has analgesic, sedative, anxiolytic effect, as it is an α 2-receptor agonist. Intraoperative visceral pain resulting from manipulation of the uterus and traction of the peritoneum is still a challenge for anesthetists. The present study hypothesized that single intravenous bolus dose of DEX added as a supplement to intrathecal anesthesia for an elective cesarean section could reduce intraoperative visceral pain, lessen blood pressure swings, and produce an acceptable sedative effect, with minimal fetal and maternal consequences.

Patients and methods

A randomized double-blinded placebo-controlled study was conducted. A total of 70 patients were randomly allocated to receive either intravenous DEX or placebo (saline) before spinal anesthesia. The primary outcomes were decreased intraoperative visceral pain. Secondary outcomes included the stability of hemodynamic parameters (blood pressure and heart rate), sedation score, time to rescue analgesia reduction, neonatal APGAR score, and any adverse effects (nausea and vomiting).

Results

There was a significant difference between the groups in the incidence of moderate to severe visceral pain (P<0.001), intraoperative fentanyl requirements (P=0.004), and longer time to rescue analgesia (P<0.001). Both groups had comparable mean blood pressure (P>0.005); however, there was a highly significant difference in heart rate (P=0.01). Moreover, a significantly higher sedation score was seen in the DEX group (2.08±0.8) in comparison with the control group (1±0). APGAR score was comparable in the studied groups.

Conclusion

As a single intravenous bolus, DEX seems to be an excellent supplement to intrathecal anesthesia for an elective cesarean section. It can reduce intraoperative visceral pain and lessen blood pressure swings and produce an acceptable sedative effect with minimal fetal and maternal influence.

Authors: Hamed Rasha A. , Magid Diaa M. , Saleh Doaa M.
Published: March 2024

Background

Urinary incontinence (UI) among women of all ages is a common disorder. UI may have a major negative effect on quality of life and cause anxiety, depression, and decreased social involvement.

Patients and methods

A prospective cohort study was conducted that involved 100 postmenopausal women experiencing urinary leakage who attended the Department of Obstetrics and Gynecology in Al-Galaa Teaching Hospital from January 2018 to July 2018. All patients had been classified into three groups: group 1 included 30 patients experiencing postmenopausal urine leakage who were performed pelvic floor exercises (PFEs), group 2 included 30 patients experiencing postmenopausal urine leakage who had been on medications (solifenacin), and group 3 included 40 patients experiencing postmenopausal urine leakage who had been under observation and placebo treatment.

Results

Regarding day and night-time micturition, there was no statistical disparity between solifenacin and PFE groups. Regarding urge and urgency incontinence, no substantial distinction between solifenacin and PFE groups was found. However, the difference between solifenacin versus placebo and PFE versus placebo was significant.

Conclusion

The research proposed versatile 5-mg solifenacin dosing as a more reliable way to decrease symptoms of overactive bladder. Moreover, the intensity of UI, pelvic floor muscle force, and stamina were increased by PFEs.

Authors: Rushd Areej M. , Said Zeinab N.A. , El-Salakawy Azza , Gad Moneira
Published: March 2024

Background

Human papilloma viruses (HPVs) are a group of viruses with high global distribution. Persistent infection with high-risk HPV (HR-HPV) genotypes had been linked to the progression of different cancers including cervical cancer. Data are insufficient about HPV status in Egypt.

Aim

This study was held to determine the HR-HPV genotypes among Egyptian women by using single-tube seminested PCR.

Patients and methods

A total of 203 cervical samples were collected and subjected to pathological examination and HR-HPV DNA detection by seminested PCR using MY09/MY11 and GP6+ primers.

Results

Of 203 examined samples, 90 (45%) tested positive for HR-HPV detection. HPV DNA was detected in 68.8 and 50% of women with cervical intraepithelial neoplasia I and cervical intraepithelial neoplasia II, respectively. However, it was detected in 41.1% of women with normal cervical pathology.

Authors: AlKamhawy Ola T.K. , Mostafa Soad Y. , El-Kholy Tawfeek A.E.-A , Zaidan Mohammed F. , Ezzat Alshaimaa A.
Published: March 2024

Background

Septal deviation is usually associated with compensatory hypertrophy of the contralateral inferior turbinate. The current treatment of anterior septal deviation is septoplasty, but there is controversy about surgery for the hypertrophied inferior turbinate.

Aim

This study aims to determine the effect of septoplasty surgery alone on the size of inferior turbinate.

Patients and methods

This prospective study was done on 40 patients who attended ENT Department of Al-Zahraa University Hospital. This study was done in the period from September 2019 to September 2020. Their age ranged from 18 to 40 years. They had septal deviation on one side and inferior turbinate hypertrophy (ITH) on the opposite side. All of them underwent septoplasty without turbinate surgery. These patients were evaluated preoperatively and 6 months postoperatively by radiological (computed tomography), endoscopic examination, and nasal obstruction symptom evaluation questionnaire.

Results

Septoplasty alone significantly decreased the thickness of the medial mucosa of hypertrophied inferior turbinate by 1.03±0.74 mm (P=0.000) at the anterior part and decrease by 0.82±1.14 mm at the middle part (P=0.000), with no statistically significant decrease at the posterior part. Moreover, it also decreased the thickness of the lateral mucosa of turbinate by 0.31±0.25 mm (P=0.000) at the anterior part, decrease by 0.42±0.39 mm at the middle part (P=0.000), and no significant decrease at the posterior part. Insignificant change of conchal bone thickness on both sides was reported.

Conclusion

We conclude that septoplasty alone saves time and cost and avoids complications and sequelae associated with turbinectomy. This in turn improves quality of life, so it can be prescribed for patients with DNS with ITH mainly at anterior and middle segment soft tissue parts, but it is not enough for surgery of patients with ITH of posterior part or conchal bone.
Correlation between epicardial fat volume as detected by echocrdiography and multidetector computed tomography with the extent and severity of coronary atherosclerosis
Authors: Ali Hassan Asmaa A. , Abdel-Aziz Islam S. , Moselhy Dina , Fereig Hanaa M.
Published: March 2024

Background

Epicardial fat is a visceral deposition of fat. It causes local inflammation and affects coronary artery disease (CAD), so it has been considered a risk factor for cardiovascular disease.

Aim

To study the relationship between epicedial fat, as measured by multidetector computed tomography and transthoracic echocardiography, and the severity of CAD using invasive coronary angiography (ICA).

Patients and methods

This is an observational study that included 100 patients with suspected CAD presented to the Department of Cardiology in Kopry Elkoppa Hospital from September 2015 to December 2017. Epicardial fat thickness (EFT) was measured by transthoracic echocardiography, and epicardial fat volume (EFV) was measured by multidetector computed tomography, and ICA was done.

Results

The studied population was divided into two groups: group A (86 patients) with significant CAD and group B (14 patients) without significant CAD. We divided group A according to the number of vessel affected by ICA into group I (single-vessel or two-vessel disease) and group II (multivessel disease). EFT and EFV were significantly increased in group II compared with group I. EFT and EFV were positively correlated with age, weight, family history of ischemic heart disease, and high Ca score more than or equal to 400. Cutoff value of EFV in predicting multivessel disease was more than or equal to 55 ml, and EFT was more than or equal to 6.5 mm. By multivariate analysis, the EFV is considered an independent risk factor for CAD.

Conclusion

EFT and EFV are sig. higher in patients with multivessel disease. Epicardial fat is an indicator and also a predictor of CAD severity and multivessel disease occurrence.

Published: March 2024

Background

Plane wart is a common disease that is caused by human papillomavirus. Many modalities of treatments are introduced in practice, but none of them proved to be effective. Potassium hydroxide (KOH) solution is a keratolytic agent with many dermatological uses.

Objective

To compare between topical KOH solution and cryotherapy in the treatment of plane warts.

Patients and methods

Lesions in each patient were divided into two groups: group A was treated with topical 5% KOH solution once at night, whereas group B was treated with cotton bud method of cryotherapy once every 2 weeks. In group A, the lesions were evaluated at second and fourth week to assess the cure rates and adverse effects. In group B, the lesions were evaluated every 2 weeks for 6–12 weeks or until warts completely disappeared. Patients were followed up for 3 months after complete cure to detect any recurrence.

Results

Regarding the response between lesions of plane warts treated with KOH 5% (group A) and cryotherapy (group B), lesions in group A showed a complete response in 17 (56.7%) patients, partial response in seven (23.3%) patients, and no response in six (20.0%) patients, whereas lesions in group B showed a complete response in 16 (53.3%) patients, partial response in nine (30%) patients, and no response in five (16.7%) patients. There was a statistically significant difference between the two groups regarding the response rate. Adverse effects included itching, erythema, crust, scar formation, hypopigmentation, and hyperpigmentation. No statistically significant differences were reported regarding adverse effect, except for crust and scar formation. Regarding crust, a statistically significant difference was found (P<0.05), with a higher percentage in group B. Regarding scar formation, a statistically significant difference was found (P<0.05), with a higher percentage in group B.

Published: March 2024

Background

Attention-deficit hyperactivity disorder (ADHD) is a childhood neurodevelopmental illness. It disrupts not only the child but also the parents. Dealing with children with ADHD can have unpleasant effects on close relatives, particularly mothers.

Objective

To detect depression and anxiety between mothers of children with ADHD.

Patients and methods

This cross-sectional study was conducted on 100 mothers of children with ADHD. Interviews were conducted with mothers and their children. Stanford-Binet Intelligence Scales and Conner's Parent Rating Scale-revised, long version, were applied to all children. Participating mothers underwent Taylor Manifest Anxiety Scale and Beck's Depression Inventory − II scale, and their socioeconomic level was measured by the El-Gilany scale for measuring family socioeconomic status.

Results

This study showed the presence of depression in 48% of mothers of children with ADHD. Presence of anxiety was seen in 64% of mothers of children with ADHD. There is a positive correlation between depression and anxiety of mothers and severity of symptoms of ADHD in their child. In our study, there is no relation between depression and anxiety of mothers and their child's type of ADHD.

Conclusion

Our study determined the presence of depression and anxiety symptoms in mothers of children with ADHD. The severity of depression and anxiety in mothers increases if the symptoms (attention deficit-hyperactivity-impulsivity) increase in their children.

Authors: Kadah Sayed M.S. , Elgaber Fatma M.A. , Mohammed Wafaa K.S.
Published: March 2024

Background

Chronic suppurative otitis media is an inflammation of middle ear of more than 2 weeks with treatment without improvement.

Aim

The aim was to evaluate the effect of drill-generated noise after mastoidectomy on hearing status of the nonoperated ear.

Patients and methods

This is a prospective study of 40 patients with unilateral chronic suppurative otitis media attending ENT Departments of Al-Zahraa University Hospital, Faculty of Medicine (Girls), Al-Azhar University, and El-Maadi Armed Forces Medical Complex during the period from August 2018 till September 2019. Patients were divided into two equal groups: group A included 20 patients who underwent mastoidectomy operations with the usage of mastoid drilling and group B underwent myringoplasty without the usage of drilling. Pure tone audiometry (PTA) and otoacoustic emissions (OAEs) were done for nonoperated ear of all patients preoperatively and at days 1, 2, and 7 postoperatively.

Results

Result showed that postoperative nonoperated ear hearing was affected in group A. This effect is not significant enough to cause hearing loss as detected by PTA but can be detected by OAE in which their amplitude deteriorated at first day postoperatively and improved after that back to the normal preoperative values within 1 week. However, hearing in nonoperated ear of group B was not affected by observation of PTA or OAE.

Conclusion

Drill-induced noise during mastoidectomy affects hearing of contralateral nonoperated ear temporarily through some outer hair cells (OHC) damage.

Authors: JAVED Mansoor , ALI Akbar , KASHIF Muhammad , ALI Muhammad , RAHMAN Saeed Ur
Published: March 2024

To find out genetic variability, heritability, and trait association among yield and yield-related traits among bread wheat genotypes, an alpha lattice design was used in triplicate manner where 50 wheat genotypes were evaluated at the University of Agriculture Peshawar during rabbi growing season 2021-22 along with a regional check genotype. Data were taken on ten parameters. All the genotypes showed significant variation among them, signifying the possibility of enhancing genetic improvement through breeding programs. Highly significant differences were found in days to heading, days to maturity, plant height, spike length, grain filling duration, number of grains per spike, biological yield and grain yield these traits indicating diversity in yield potential. Moderate to low heritability values were noted for most of the traits. The study exhibits positive correlations for plant height with grain yield, spike length with biological yield, and harvest index with grain yield. On the basis of high heritability and positive correlation of grain yield with other traits, it is recommended that G-41, G-3, G-12, G-37, G-34 and G-14 genotypes which have the potential to be incorporate in further breeding programs.

Published: March 2024

Jellyfish (JF) are essential to marine ecosystems. However, JF that increases rapidly can have negative effects. On 3-4 August 2022, a significant JF (Lobonemoides robustus Stiasny, 1920) bloom was observed along Cox’s Bazar coast (from Najdirartek to Sabrang) in Bangladesh. The goal of the current investigation was to identify the fatty acids (FAs) and amino acids (AAs) of L. robustus. The AAs were determined using liquid chromatography–tandem mass spectrometry (LC-MS/MS) analysis, while the FAs were determined using a gas chromatographic system with a flame ionisation detector. The most prevalent AA was glycine. The most common FA was linoleic acid (C18:3) (0.43%), followed by myristic acid (0.12%), cis-9-oleic acid (0.18%), gamma-linolenic acid (0.24%), and heptadecanoic acid (0.29%). Based on its AA and FA contents, L. robustus can be a great candidate for the potentially sustainable manufacture of nutraceutical, cosmeceutical, and biomedical natural products to improve health and well-being. In addition, the edible L. robustus could be exported to other countries, thus way it can play a major role in achieving a blue economy.

A field experiment on the effect of zinc and molybdenum application on the yield of lentil was carried out at The University of Agriculture Peshawar during the Rabi season of 2021. The experiment was carried out in a randomised complete block design with three replications. Four levels of molybdenum (0, 1, 2 and 3 kg ha−1) and 0.5% zinc foliar spray at different intervals of lentil crop (control, 50 days after sowing, 100 days after sowing, 50 days after sowing + 100 days after sowing) were tested in the experiment. The results revealed that 3 kg ha−1 of molybdenum enhanced plant height (55 cm), nodules plant−1 (25), branches plant−1 (7), days to flowering (107) and maturity (159), dry matter of leaves at the flowering stage (64 g m−2), dry matter of leaves at the maturity stage (113 g m−2), dry matter of branches at the physiological maturity stage (304 g m−2), dry matter of pods at the maturity stage (439 g m−2), pods plant−1 (92), seeds pod−1 (2.0), 1000-seed weight (31 g), biological yield (3207 kg ha−1), and seed yield (1002 kg ha−1). Zinc foliar spray (0.5%) at 50 days after sowing + 100 days after sowing of lentil crop improved the dry matter of leaves at the flowering stage (62 g m−2), days to first flowering (109), days to physiological maturity (157), dry matter of leaves at the physiological maturity stage (111 g m−2), dry matter of pods at the physiological maturity stage (435 g m−2), pods plant−1 (91), 1000 seed weight (32 g), biological yield (3236 kg ha−1) and seed yield (1026 kg ha−1). Lastly, scatterplots revealed a significant correlation of grain and biological yield with their components. It is concluded that molybdenum application at a rate of 3 kg ha−1 and 0.5% zinc foliar spray at 50 days after sowing + 100 days after sowing of the lentil crop increased seed yield and is thus recommended for the Peshawar region.

La instalación de piso de porcelanato es una práctica común en la construcción y renovación de espacios interiores. A pesar de su popularidad, existe una falta de atención significativa en la literatura científica hacia las condiciones subestándar y los riesgos ergonómicos asociados con esta actividad. Este artículo tiene como objetivo evaluar los riesgos ergonómicos y las condiciones subestándar presentes en la instalación de piso de porcelanato en construcciones civiles mediante la observación directa y la aplicación del método OWAS, orientado a la adopción de estrategias sobre la gestión de riesgos laborales. La investigación se basa en un estudio de campo aplicado en el proceso constructivo de un centro comercial en la ciudad de Guayaquil. Los resultados revelan que el personal responsable de la instalación de piso de porcelanato, está expuesto a una serie de factores de riesgo ergonómico, incluyendo posturas incómodas y movimientos forzados con una frecuencia significativa, lo que puede dar lugar a trastornos musculoesqueléticos y enfermedades profesionales. Esta investigación determinó que, en la instalación de piso de porcelanato, en la fase de montaje de la pieza, se experimenta un nivel importante de riesgo ergonómico, recomendándose adoptar medidas correctivas lo antes posible. Se evidencia también que, las condiciones subestándares más frecuentemente encontradas en los lugares de trabajo son: el diseño de la estación de trabajo (21,3%), el orden y limpieza en el área (17,2%), la señalización de seguridad y emergencia (16,4%), el uso de equipos de protección personal (12,3%) y los procedimientos y métodos de trabajo (12,3%). Además, se identifican otras variables incidentes en los trastornos músculo-esqueléticos de los trabajadores como: la limitada capacitación, la planificación de los períodos de descanso durante la jornada, la ventilación y la iluminación en el área de trabajo. Estas deficiencias exigen la adopción de medidas correctivas oportunas en el proceso constructivo, con el fin de evitar el impacto negativo en la salud de los trabajadores, en la productividad de la industria de la construcción y en la calidad del proyecto.
