Perceived barriers and opportunities of providing quality family planning services among Palestinian midwives, physicians and nurses in the West Bank: a qualitative study.

BACKGROUND: Despite advancements in family planning (FP) services, several barriers persist in the Occupied Palestinian territory (oPt), blocking women's access to suitable, high-quality and equitable FP services. The aim of this study was to understand how healthcare providers perceive their abilities, barriers and opportunities in providing good quality FP services. Furthermore, it seeks to explore knowledge and training regarding FP among healthcare providers engaged in providing FP services. METHODS: A qualitative study was undertaken from August to September 2022 in seven Primary Health Care (PHC) clinics distributed in three governorates and operating under the Palestinian Ministry of Health (MoH) in the West Bank. Semi-structured, in-depth face-to-face interviews were conducted with 13 health providers (Physicians, midwives and nurses), using an interview guide in Arabic language. Transcripts were subsequently analyzed using the six phases of reflexive thematic analysis. RESULTS: FP services face various challenges, including shortages in resources such as staff, supplies, infrastructures and FP methods. Midwives possess significant potentials to offer accessible, high-quality, efficient and equitable FP services, yet, their capacities remain underutilized, representing a missed opportunity for a country like Palestine. The study provided a current overview of FP services while illustrating the need for quality FP services and the need for an updated continuous education and training, updated standardized guidelines and protocols and supportive supervision are needed across all levels of healthcare providers. Finally, providers reported a wide range of structural barriers to FP services. CONCLUSIONS: It is crucial to meticulously address both community-related and health system factors to enhance the fulfillment of FP needs and reduce unintended and closely spaced pregnancies. Policymakers should invest in the development of laws and regulations regarding FP services, promoting a comprehensive and holistic approach to FP services. This includes formulating supportive policies, capacity building of human resources and maintaining security of FP commodities.

Foodborne botulism outbreak with potential new management options.

OBJECTIVES: To shed some light on a potential therapeutic modality that may facilitate resolution of botulism symptoms, namely 3,4-diaminopyridine (3,4-DAP). METHODS: In Riyadh, Saudi Arabia, we recently encountered a foodborne botulism outbreak that, luckily, was discovered early. In Prince Sultan Military Medical city, we admitted, during a period of approximately 3 weeks, 15 probable cases, 2 of which were excluded due to more likely alternative diagnoses. We report in this case series 13 highly suspected cases of botulism that we encountered during the outbreak. RESULTS: A total of 12 out of 13 patients required intensive care unit (ICU) admission, one of which required intubation. Symptoms included cranial nerve palsies, gastrointestinal symptoms, limb and respiratory muscle weakness. Patients showed clinical improvement when received botulinum antitoxin and 3,4-DAP if given early in the course of the disease. CONCLUSION: Early admisntration of 3,4-DAP may facilitate recovery and prevent disease progression. Larger prospective trials should be carried out to confirm that.

Ultramicroscopic organization of the exterior olfactory organ in Anguilla vulgaris in relation to its spawning migration.

Background: Catadromous fishes have well-developed elongated olfactory organs with numerous lamellae and different types of receptor neurons related to their breeding migration. Aim: The current study showed how the olfactory system adapted to the catadromous life. Our work declared the need of the migratory fishes for the sense of smell that is exhibited by a higher number of the olfactory lamellae and the receptor neuron verification in the olfactory epithelium. Methods: Ten specimens of fully grown, but pre-matured, silver eels of Anguilla vulgaris were captured at the outlet of Edco Lake, overlooking the Mediterranean Sea, east of Alexandria. Olfactory rosettes were dissected and fixed for scanning electron microscope (SEM) and transmission electron microscope (TEM). Results: Our study gave a morphological description of the olfactory system of A. vulgaris. At the ultrastructural level using SEM and TEM, one olfactory rosette was provided with 90-100 flat radial olfactory lamellae. The nasal configuration allowed water to enter and exit, transferring odorant molecules to olfactory receptor cells which comprise long cylindrical ciliated and microvillous receptors as well as rod-tipped cells. These cells are bipolar neurons with upward dendritic knobs. The olfactory epithelia also include crypt receptor cells. Interestingly, the olfactory neurons are delimited by nonsensory supporting cells, including long motile kinocilia and sustentacular supporting cells beside mucus secretory goblet cells and ionocytes or labyrinth cells that contribute to the olfaction process. Conclusion: Olfaction is crucial in all vertebrates, including fishes as it involves reproduction, parental, feeding, defensive, schooling, and migration behaviors. Here, A. vulgaris is an excellent model for catadromous fishes. It has a well-developed olfactory organ to cope with the dramatic climate change, habitat loss, water pollution, and altered ocean currents effect during their catadromous life for reproduction.

Production and characterization of novel marine black yeast's exopolysaccharide with potential antiradical and anticancer prospects.

The marine black yeasts are characterized by the production of many novel protective substances. These compounds increase their physiological adaptation to multi-extreme environmental stress. Hence, the exopolysaccharide (EPS) producing marine black yeast SAHE was isolated in this study. It was molecularly identified as Hortaea werneckii (identity 98.5%) through ITS1 and ITS4 gene sequencing analysis. The physicochemical properties of the novel SAHE-EPS were investigated through FTIR, GC-MS, TGA, ESM, and EDX analysis, revealing its heteropolysaccharide nature. SAHE-EPS was found to be thermostable and mainly consists of sucrose, maltose, cellobiose, lactose, and galactose. Furthermore, it exhibited an amorphous texture and irregular porous surface structure. SAHE-EPS showed significant antiradical activity, as demonstrated by the DPPH radical scavenging assay, and the IC50 was recorded to be 984.9 µg/mL. In addition, SAHE-EPS exhibited outstanding anticancer activity toward the A549 human lung cancer cell line (IC50 = 22.9 µg/mL). Conversely, it demonstrates minimal cytotoxicity toward the WI-38 normal lung cell line (IC50 = 203 µg/mL), which implies its safety. This study represents the initial attempt to isolate and characterize the chemical properties of an EPS produced by the marine black yeast H. werneckii as a promising antiradical and anticancer agent.

Barriers to Elderly Health Care in the Occupied Palestinian Territories.

This study examined different barriers to the access and utilization of primary health care services by the elderly in the occupied Palestinians territories. We collected quantitative data from a larger convenience sample of a national survey of 1299 persons in the occupied Palestinian territories (oPt) that examined the effects of Israel's colonization and its effects on health care delivery between October 2021 and February 2022. The research tool was based on the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) questionnaire. The data was obtained from 76 elderly participants with a mean age of 68.33 years standard deviation (SD = 7.09 years). The majority (75%) reported having at least one chronic health issue and having limited access to health care. They had all finished at least six years of education. The participants claimed having health insurance, while 47.4 percent reported paying for out-of-pocket expenses and medical care was a burden. Access and affordability of health care was a problem for 70 percent of participants. Older persons and their families face access to care issues created by political, geographic, and economic barriers. Poor incomes, war-like conditions, a weak health care system, and a lack of comprehensive care delivery all impact their health.

Experiences of Palestinian patients with hospital services: a mixed-methods study.

BACKGROUND: This study aimed at assessing patient experiences with hospital services and key factors associated with better experiences. METHODS: The study design is cross-sectional supported by qualitative interviews. The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) was used as data collection instrument. A convenience sample of 391 volunteers aged ≥18 years participated in this study. Qualitative interviews were conducted with patients and healthcare providers to further enrich and explain the quantitative results. RESULTS: The average age of the sample was 41.34, SD (16.4), range (18-87). Females represented 61.9% of the whole sample. Almost 75% were from the West Bank and 25% from the Gaza Strip. The majority of respondents reported that doctors and nurses were respectful, listened to them and explained clearly to them always or most of the time. Only 29.4% of respondents were given written information about the symptoms they may have after discharge from the hospital. Factors that were independently associated with higher scores on the HCAHPS scale were; being females (coef: 0.87, 95% CI: 0.157 to 1.587, p=0.017), being healthy (coef: -1.58, 95% CI: -2.458 to -0.706, p=0.000), being with high financial status (coef: 1.51, 95% CI: 0.437 to 2.582, p=0.006), being from Gaza (coef: 1.45, 95% CI: 0.484 to 2.408, p=0.003) and who visited hospitals outside of Palestine (coef: 3.37, 95% CI: 1.812 to 4.934, p=0.000). Overcrowding, weak organisational and management processes, and inadequate supply of goods, medicines, and equipment were reported factors impeding quality services via in-depth interviews. CONCLUSIONS: The overall hospital experiences of Palestinian patients were moderate but varied significantly based on patients' factors such as sex, health status, financial status and residency as well as by hospital type. Hospitals in Palestine should invest more in improving their services including communications with patients, the hospital environment and communication with patients.

Menstrual health and hygiene among young Palestinian female university students in the West Bank: a cross-sectional study.

OBJECTIVE: We investigated some aspects of menstrual health and hygiene among young female students at Birzeit University in the West Bank of the occupied Palestinian territory. DESIGN: Cross-sectional study in a large central university. PARTICIPANTS: Out of a total of 8473 eligible female students, a calculated sample size of 400 students aged between 16 and 27 years was obtained.SettingLarge central university, West Bank, occupied Palestinian territory (oPt). MEASURES: An anonymous structured international research instrument consisting of 39 questions based on the Menstrual Health Questionnaire, in addition to few questions relevant to the context, was administered. RESULTS: 30.5% of participants were not informed about menstruation before menarche, and 65.3% reported that they were not ready when they got their first period. The highest reported source of information regarding menstruation was family (74.1%), followed by school (69.3%). About 66% of respondents reported that they need more information on various topics of menstruation. The most common type of menstrual hygiene products used were single-use pads (86%), followed by toilet paper (13%), nappies (10%) and reusable cloths (6%). Of the total 400 students, 14.5% reported that menstrual hygiene products are expensive, and 15.3% reported that they always/sometimes had to use menstrual products that they do not like because they are cheaper. Most (71.9%) of the respondents reported that they used menstrual products for longer time than recommended due to inadequate washing facilities at the university campus. CONCLUSIONS: The findings provide useful evidence on the lack and the need for menstrual-related information for female university students, inadequate infrastructure to help them manage their menstruation with dignity and pointed to some menstrual poverty in accessing menstrual products. A national intervention programme is needed to increase awareness regarding menstrual health and hygiene among women in local communities and female teachers in schools and universities to enable them to disseminate information to and meet the practical needs of girls at home, at school and at the university.

Variation in Anti-inflammatory, Anti-arthritic, and Antimicrobial Activities of Different Extracts of Common Egyptian Seaweeds with an Emphasis on Their Phytochemical and Heavy Metal Contents.

The anti-inflammatory, anti-arthritic, and antimicrobial activities of some common Egyptian seaweeds in addition to their phytochemical and heavy metal contents were investigated. Phytochemical screening of the seaweed extracts showed the presence of different primary and secondary metabolites with different concentrations according to their species and the used solvent. The ethanolic extract of Colpmenia sinuosa (CSBE2) exhibited the maximum anti-inflammatory and anti-arthritic activity at 1000 µg/ml concentration compared to other seaweed extracts. The dichloromethane extract of Corallina officinalis (CORM) exerted the highest antimicrobial activity with an average inhibition zone diameter (AV) = 15.29 mm and activity index (AI) = 1.53 and with the highest antagonistic activity against Escherichia coli (28 mm). It is followed by Ulva linza ethanolic extract (ULGE2) which recorded (AV) of 14.71 mm and (AI) of 1.30 with the highest antifungal activity against Candida albicans (30 mm). The collected seaweeds would therefore be a very promising source for treating inflammatory, arthritic, and microbial diseases. Moreover, the investigated seaweeds showed variable concentrations of heavy metals among various species. The mean concentrations of the heavy metals took the following order: Fe > Zn > Mn > Ba > Cu > As > Cr > Ni > Pb > V > Cd > Se > Co > Mo. Based on the permissible limits set by the WHO and CEVA, Pb and Ni in the studied seaweeds were found to be within the permissible limits, whereas Cd and Zn contents were at the borderline. Significant correlations were observed between studied parameters. The estimated daily intakes for most heavy metals were lower than the recommended daily intakes.

Exploring the impact of indication on variation in rates of intrapartum caesarean section in six Palestinian hospitals: a prospective cohort study.

BACKGROUND: Caesarean section rates are rising globally. No specific caesarian section rate at either country-level or hospital-level was recommended. In Palestinian government hospitals, nearly one-fourth of all births were caesarean sections, ranging from 14.5 to 35.6%. Our aim was to assess whether variation in odds for intrapartum caesarean section in six Palestinian government hospitals can be explained by differences in indications. METHODS: Data on maternal and fetal health were collected prospectively for all women scheduled for vaginal delivery during the period from 1st March 2015 to 30th November 2016 in six government hospitals in Palestine. Comparisons of proportions in sociodemographic, antenatal obstetric characteristics and indications by the hospital were tested by χ2 test and differences in means by one-way ANOVA analysis. The odds for intrapartum caesarean section were estimated by logistic regression. The amount of explained variance was estimated by Nagelkerke R square. RESULTS: Out of 51,041 women, 4724 (9.3%) underwent intrapartum caesarean section. The prevalence of intrapartum caesarean section varied across hospitals; from 7.6 to 22.1% in nulliparous, and from 5.8 to 14.1% among parous women. The most common indications were fetal distress and failure to progress in nulliparous, and previous caesarean section with an additional obstetric indication among parous women. Adjusted ORs for intrapartum caesarean section among nulliparous women ranged from 0.42 (95% CI 0.31 to 0.57) to 2.41 (95% CI 1.70 to 3.40) compared to the reference hospital, and from 0.50 (95% CI 0.40-0.63) to 2.07 (95% CI 1.61 to 2.67) among parous women. Indications explained 58 and 66% of the variation in intrapartum caesarean section among nulliparous and parous women, respectively. CONCLUSION: The differences in odds for intrapartum caesarean section among hospitals could not be fully explained by differences in indications. Further investigations on provider related factors as well as maternal and fetal outcomes in different hospitals are necessary.

Knowledge, attitudes and practices of Egyptian healthcare professionals toward therapeutic drug monitoring service as a principal component of personalized medicine.

Aim: To assess pharmacists' and physicians' knowledge, attitudes and practices toward therapeutic drug monitoring (TDM) service at the Children's Cancer Hospital Egypt 57357. Materials & methods: This was a single-site cross-sectional study where all practicing pharmacists and physicians were eligible to participate. Results: A statistically significant difference in the knowledge scores between pharmacists and physicians (p = 0.022) was found. In general, attitudes toward TDM among pharmacists and physicians were positive. Regarding practices, pharmacists were more likely than physicians to agree or strongly agree that they have studied some scientific references on TDM (p = 0.034), but more physicians recommend the TDM service (p = 0.046). Conclusion: A multidisciplinary educational program in Egypt for TDM for both medicine and pharmacy staff will improve interprofessional collaboration in the clinical setting, leading to better personalized medication management.

The objective of the present survey was to evaluate the knowledge, attitudes and practices of pharmacists and physicians toward therapeutic drug monitoring (TDM) services at the Children's Cancer Hospital Egypt 57357. TDM is defined as 'measuring the amount of specific drugs in patients' blood to ensure that the concentrations of administered drugs are both effective and safe'. A single-centered study was conducted at the CCHE where all pharmacists and physicians participated. There was a remarkable difference in the knowledge scores between pharmacists and physicians. Generally, both pharmacists and physicians demonstrated positive attitudes toward TDM. In real-life practice, pharmacists were more likely than physicians to agree that they had scientific evidence about TDM. Multidisciplinary educational programs for TDM among physicians and pharmacists would improve interprofessional collaboration for the benefit of patients in Egypt.

Impact of Clinical Pilates Exercise on Pain, Cardiorespiratory Fitness, Functional Ability, and Quality of Life in Children with Polyarticular Juvenile Idiopathic Arthritis.

Objective: This study intended to examine the effects of Pilates exercise on pain, cardiorespiratory fitness, functional ability, and quality of life in children with polyarticular juvenile idiopathic arthritis. Methods: Forty children with polyarticular JIA aged 10−14 years old were randomly allocated into two groups: the control group (n = 20) received conventional physical therapy (CPT), and the experimental group (n = 20) received clinical Pilates exercises combined with CPT. Patients in both groups received their program three times/week for 3 months. Pain, cardiorespiratory fitness, functional ability, and quality of life were assessed through the visual analogue scale, cardiopulmonary exercise test, 6 min walk test, and PedsQL scale, respectively, just before and after treatment. Results: Pain (p = 0.001), cardiorespiratory markers (all p < 0.05), functional ability (p = 0.002), and overall quality of life (p = 0.007) improved significantly in the experimental groups compared to the control group. Conclusion: Incorporating Pilates exercises into CPT is likely more effective for decreasing pain intensity, improving cardiorespiratory fitness, augmenting functional ability, and promoting quality of life in children with JIA than CPT alone.

Suggested Sustainable Medical and Environmental Uses of Melanin Pigment From Halotolerant Black Yeast Hortaea werneckii AS1.

The marine ecosystem is a complex niche with unique environmental circumstances. Microbial communities from the sea are one of the main origins of compounds with tremendous capabilities. Marine yeasts have the ability to produce secondary metabolites that are architecturally distinct from those found in terrestrial species. Melanin pigment synthesized by marine halotolerant black yeast Hortaea werneckii AS1 isolated from Mediterranean salt lakes in Alexandria, Egypt was found to exert a radical scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) with an IC50 of 61.38 µg/ml. Furthermore, it showed no cytotoxicity toward human skin fibroblast cell line (HSF) with an IC50 value above 0.1 mg/ml. The antimicrobial capability of the pigment was revealed against the tested number of bacterial and fungal strains with the highest inhibition zone of 25 mm against Aeromonas sp. and a growth inhibition percentage up to 63.6% against Aspergillus niger. From an environmental impact point of view, the pigment disclosed a heavy metal removal efficiency of 85.7, 84.8, and 81.5% for Pb2+, Cd2+, and Ni2+, respectively, at 100 mg/L metal concentration. The previously mentioned results suggested melanin from H. werneckii AS1 as a promising biocompatible candidate in various medical, cosmetics, pharmaceutical, and environmental applications.

Optimization of melanin pigment production from the halotolerant black yeast Hortaea werneckii AS1 isolated from solar salter in Alexandria.

BACKGROUND: Melanins are one of the magnificent natural pigments synthesized by a wide range of microorganisms including different species of fungi and bacteria. Marine black yeasts appear to be potential prospects for the synthesis of natural melanin pigment. As a result, the goal of this research was to isolate a marine black yeast melanin-producing strain and improve the culturing conditions in order to maximize the yield of such a valuable pigment. RESULTS: Among five locally isolated black yeast strains, the only one that demonstrated a potent remarkable melanin pigment production was identified using ITS rDNA as Hortaea werneckii AS1. The extracted pigment's physiochemical characterization and analytical investigation with Ultraviolet-Visible (UV) spectrophotometry, Fourier Transform-Infrared spectroscopy (FTIR), and Scanning Electron Microscope (SEM) confirmed its nature as a melanin pigment. The data obtained from the polynomial model's maximum point suggested that CaCl2, 1.125 g/L; trace element, 0.25 ml/L; and a culture volume 225 mL/500 mL at their optimal values were the critical three elements impacting melanin production. In comparison with the baseline settings, the response surface methodology (RSM) optimization approach resulted in a 2.0 - fold improvement in melanin output. CONCLUSIONS: A maximum melanin yield of 0.938 g/L proved the halotolerant H. werneckii AS1 potentiality as a source for natural melanin pigment synthesis 'when compared to some relevant black yeast strains' and hence, facilitating its incorporation in a variety of pharmaceutical and environmental applications.

Development of Sedative Dexmedetomidine Sublingual In Situ Gels: In Vitro and In Vivo Evaluations.

Intravenous dexmedetomidine (DEX) is currently approved by the FDA for the sedation of intubated patients in intensive care units to reduce anxiety and to augment postoperative analgesia. Bradycardia and hypotension are limitations associated with the intravenous administration of DEX. In this study, DEX sublingual in situ gels were developed and assessed for their pH, gelling capacity, viscosity, mucoadhesion and in vitro drug release. The optimized gelling system demonstrated enhanced mucoadhesion, superior gelling capacity, reasonable pH and optimal rheological profile. In vivo, compared to the oral solution, the optimal sublingual gel resulted in a significant higher rate and extent of bioavailability. Although the in situ gel had comparable plasma levels to those observed following intravenous administration, significant amelioration of the systemic adverse reactions were attained. As demonstrated by the hot plate method, a sustained duration of analgesia in rats was observed after sublingual administration of DEX gel compared to the intravenously administered DEX solution. Furthermore, no changes in systolic blood pressure and heart rate were recorded in rats and rabbits, respectively, after sublingual administration of DEX. Sublingual administration of DEX in situ gel provides a promising approach for analgesia and sedation, while circumventing the reported adverse reactions associated with intravenous administration of DEX.

Pharmacokinetics and Pharmacodynamics of Dexmedetomidine Administered as an Adjunct to Bupivacaine for Transversus Abdominis Plane Block in Patients Undergoing Lower Abdominal Cancer Surgery.

BACKGROUND: Despite the growing interest in dexmedetomidine as an adjunct to truncal blocks, little is known about the systemic absorption of dexmedetomidine after these blocks and its role in analgesia and in hemodynamics. OBJECTIVE: We investigated the pharmacokinetics and pharmacodynamics of dexmedetomidine as an adjunct to transversus abdominis plane (TAP) block in patients undergoing lower abdominal cancer surgery. METHODS: Twenty-four adult patients were randomized to receive a bilateral single-injection TAP block before surgery with 20 mL of bupivacaine 0.5% (TAP group, n = 12) or combined with 1 µg/kg dexmedetomidine (TAP-DEX group, n = 12) and diluted with saline to a volume of 40 mL (20 mL on each side). Plasma concentrations of dexmedetomidine and its pharmacokinetics were investigated using non-compartmental methods, postoperative analgesia, hemodynamics, and adverse events (nausea, vomiting, itching, hypotension, bradycardia, and respiratory depression). RESULTS: Dexmedetomidine was detected in the plasma of 11 patients in the TAP-DEX group. The mean dexmedetomidine peak plasma concentration (Cmax) was 0.158 ± 0.085 (range, 0.045-0.31) ng/mL. The median time to reach peak plasma concentration of dexmedetomidine (Tmax) was 15 (15-45) min. From 2 to 8 h postoperatively, visual analog pain scale (VAS) scores at rest and during movement were significantly lower in the TAP-DEX group. Analgesia time was (11.3 ± 3.12 vs 9.0 ± 4.69 h; P = 0.213) and postoperative morphine consumption was (7.4 ± 3.24 vs 11.5 ± 4.46 mg; P = 0.033) in TAP-DEX and TAP groups, respectively. Lower mean heart rate and mean blood pressure were recorded in the TAP-DEX group intraoperatively and 2 h postoperatively (P < 0.05). Except for mild nausea and vomiting, no adverse events were recorded in either group. CONCLUSION: Systemic absorption of dexmedetomidine administered in a TAP block is common. Direct central effects on the locus coeruleus caused by this systemic absorption may play a role in the analgesia and hemodynamic effects produced by TAP-dexmedetomidine in addition to local mechanisms.

Pharmacokinetics and Pharmacodynamics of 3 Doses of Oral-Mucosal Dexmedetomidine Gel for Sedative Premedication in Women Undergoing Modified Radical Mastectomy for Breast Cancer.

BACKGROUND: Buccal dexmedetomidine (DEX) produces adequate preoperative sedation and anxiolysis when used as a premedication. Formulating the drug as a gel decreases oral losses and improves the absorption of buccal DEX. We compared pharmacokinetic and pharmacodynamic properties of 3 doses of buccal DEX gel formulated in our pharmaceutical laboratory for sedative premedication in women undergoing modified radical mastectomy for breast cancer. METHODS: Thirty-six patients enrolled in 3 groups (n = 12) to receive buccal DEX gel 30 minutes before surgery at 0.5 µg/kg (DEX 0.5 group), 0.75 µg/kg (DEX 0.75 group), or 1 µg/kg (DEX 1 group). Assessments included plasma concentrations of DEX, and pharmacokinetic variables calculated with noncompartmental methods, sedative, hemodynamic and analgesic effects, and adverse effects. RESULTS: The median time to reach peak serum concentration of DEX (Tmax) was significantly shorter in patients who received 1 µg/kg (60 minutes) compared with those who received 0.5 µg/kg (120 minutes; P = .003) and 0.75 µg/kg (120 minutes; P = .004). The median (first quartile-third quartile) peak concentration of DEX (maximum plasma concentration [Cmax]) in plasma was 0.35 ng/mL (0.31-0.49), 0.37 ng/mL (0.34-0.40), and 0.54 ng/mL (0.45-0.61) in DEX 0.5, DEX 0.75, and DEX 1 groups (P = .082). The 3 doses did not produce preoperative sedation. The 1 µg/kg buccal DEX gel produced early postoperative sedation and lower intraoperative and postoperative heart rate values. Postoperative analgesia was evident in the 3 doses in a dose-dependent manner with no adverse effects. CONCLUSIONS: Provided that it is administered 60-120 minutes before surgery, sublingual administration of DEX formulated as an oral-mucosal gel may provide a safe and practical means of sedative premedication in adults.

Stability Study and Clinical Evaluation of Lipid Injectable Emulsion in Parenteral Nutrition Admixtures Used for Preterm Neonates.

BACKGROUND: Intravenous administration of parenteral nutrition (PN) admixtures containing 4-oil lipid injectable emulsion (ILE) in preterm neonates is usually prohibited because of limited clinical data. The authors evaluated the stability, safety, and efficacy of PN admixtures containing 4-oil ILE, for the first time, in preterm neonates. METHODS: A series of PN admixtures were prepared for consecutive administration in preterm neonates over a period of 15 days. Admixture stability was assessed after 24 hours of storage at 25 and 37 °C via visual inspection and measurement of mean droplet size (MDS). Safety and efficacy of the admixtures in preterm neonates were assessed via serum triglyceride levels and body weight increase measurements, respectively. RESULTS: PN admixtures were stable at 25 °C and had MDS ˂500 nm. After 15 days, there was a significant increase in body weight (P ≤ .0001) and level of serum triglycerides (P ≤ .0001), compared with the level before PN administration. CONCLUSIONS: PN admixtures containing 4-oil ILE were stable at 25 °C and showed instability at 37 °C. Therefore, it is recommended to keep the temperature during administration of PN admixtures at 25 °C. PN admixtures were well tolerated and safe over a period of 8 days while providing a balanced fatty acid supply. Tight monitoring of serum triglyceride level is essential, particularly in neonates of low birth weight and/or young gestational age, to avoid hypertriglyceridemia. Hence, the use of these PN admixtures is expected to be beneficial in terms of being cost-effective and reducing the contamination risks.

Severe cutaneous adverse drug reactions: Incidence, clinical patterns, causative drugs and modalities of treatment in Assiut University Hospital, Upper Egypt.

Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and overlap SJS/TEN are life-threatening diseases that are most frequently caused by drugs. Much debate remains about the role of systemic corticosteroids (SCs) in their treatment. Our aim to determine the incidence, causative drugs, the role and side effects of SCs in severe cutaneous adverse reactions (SCARs), in Assiut University Hospital (AUH). Patients This study was conducted in Department of Dermatology at AUH, from 2012 to 2017. All patients with SJS, overlap SJS/TEN and TEN admitted during this period were included in the study. Eighty-three patients with SCARs were included in this study. The most common type was SJS (67.5%). The incidence ranged from 1.7% in 2012 to 7.7% in 2017. Carbamazepine, valproic acid, lamotrigine, diclofenac sodium, and flucloxacillin-amoxicillin were the most common causative drugs. The most common side effects of SCs were peptic ulcer (55.5%) and hypertension (51.8%). The mortality rate in patients treated with SCs was 100% in TEN, 33.3% in overlap SJS/TEN and 16.3% in SJS. The patients of SCARs must be aware of the causative drugs and must never be re-administered. SCs in treatment of SCARs may increase the complications and the mortality rate.

Analgesic Effect of Morphine Added to Bupivacaine in Serratus Anterior Plane Block Following Modified Radical Mastectomy. Only a Local Effect? Randomized Clinical Trial.

BACKGROUND: Serratus anterior plane (SAP) block, a novel regional anesthetic procedure, involves the anterolateral chest wall. Opioid receptors have been found on peripheral nerve terminals, so morphine may have a local action. OBJECTIVE: This work aimed at exploring the analgesic efficacy of morphine added to bupivacaine in SAPB in patients for whom modified radical mastectomy was conducted and whether it is a mere local effect. METHODS: Forty female patients were planned to have modified radical mastectomy participated in the study. Patients were randomly divided into two groups; Control group (C): received ultrasound-guided serratus anterior plane block with 20 mL of bupivacaine hydrochloride 0.25%; Morphine group (M): received the same in addition to 10 mg morphine sulfate. Intra- and post-operative blood samples were taken for the assessment of morphine serum levels. All patients were assessed for VAS scores during rest and movement (VAS-R and VAS-M). Time to the first request and the total amount of the rescue analgesia were recorded. RESULTS: In group M, Morphine was not detected in the plasma of all patients. Both VAS-R and VAS-M were significantly higher in group C than in group M (P<0.001) and (P≤0.003), respectively. Time to the first request of rescue analgesia was 8.5 h in group C compared to 20 h in group M (P=0.005) with a median dose of acetaminophen consumption of 2 g in group C compared to 1 g in group M (P=0.006). CONCLUSION: Ten mg of morphine, when added to bupivacaine in SAPB, improved postoperative analgesia in patients to whom modified radical mastectomy was conducted. This effect seems to be attributed merely to local mechanisms. REGISTRATION: The registration number of this study is NCT02962024 at www.clinicaltrial.gov.
