Plasma exchange (PE) versus intravenous immunoglobulin (IVIG) for the treatment of Guillain-Barré syndrome (GBS) in patients with severe symptoms: A systematic review and meta-analysis.

Background and purpose: Guillain- Barré syndrome (GBS) is a neuropathic condition that leads to the rapid development of impairments and is characterized by weakness and numbness or tingling sensation in the legs and arms and sometimes loss of movement and feeling in the legs, arms, upper body, and face. Currently, the cure for the disease is yet to be developed. However, treatment options such as intravenous immunoglobulin (IVIG) and plasma exchange (PE) have been used to minimize the symptoms and duration of the disease. Therefore, this systematic review and meta-analysis compared the efficacy of IVIG and PE in treating GBS patients with severe symptoms. Methodology: Six electronic databases, including PubMed, Embase, Scopus, ScienceDirect, Medline, and Google scholar, were scoured for articles related and relevant to our research. Additionally, more studies were obtained through the reference lists of the studies retrieved from these electronic databases. Quality assessment and statistical data analysis were conducted using Review Manager software (RevMan 5.4.1). Results: The search for relevant articles resulted in 3253 articles, of which only 20 were included for review in the current study. A sub-group analysis indicated no significant difference in the curative effect (Hughes score reduces by at least one score 4 weeks after GBS treatment; OR: 1.00; 95% CI: 0.66-1.52; p = 1.00 and Achieving grade 0 or 1 on Hughes scale; OR: 1.03; 95% CI: 0.27-3.94; p = 0.97). Similarly, the statistical showed that the difference in length of hospitalization and duration of mechanical ventilation was insignificant between the IVIG and PE group (Standard Mean Difference (SMD): -0.45; 95% CI: -0.92, 0.02; I2 = 91%; p = 0.06 and SMD: -0.54; 95% CI: -1.67, 0.59; I2 = 93%; p = 0.35, respectively). Moreover, the meta-analysis did not find any significant difference in the risk of GBS relapse (RR: 0.47; 95% CI: 0.20-1.14; p = 0.10) and risk of complications related to the treatment regimens (RR: 1.03; 95% CI: 0.71-1.48; p = 0.89). However, the statistical analysis of outcomes from 3 studies showed that the risk of discontinuation was significantly lower in the IVIG group than in the PE group (RR: 0.22; 95% CI: 0.06-0.88; p = 0.03). Conclusion: Our study suggests that IVIG and PE have similar curative effects. Similarly, IVIG seems easier to use and thus can be preferred for treating GBS.

Circadian hormone secretion of enteroendocrine cells: implication on pregnancy status.

The timing of food intake is a key cue for circadian rhythms in humans and animals. In response to food intake, gut hormones called incretin are produced by intestinal enteroendocrine cells in a circadian rhythm that stimulates insulin secretion and regulates body weight and energy expenditure. Pregnancy is associated with the expansion of ß cells, the risk of gestational diabetes mellitus, and excessive weight gain. The timing of food intake is a good way to address metabolic complications during pregnancy. The current review focuses on the circadian rhythms and biological actions of enteroendocrine hormones and their associations with pregnancy status, specifically topics like food intake and gut circadian rhythms, the circadian secretion of enteroendocrine peptides, and the effects of these factors during pregnancy.

Efficacy of Emla (Eutectic Mixture of Local Anaesthetics) and Let (Lidocaine, Epinephrine, Tetracaine) for Topical Use in Wound Management for Children: A Systematic Review and Meta-Analysis.

Lacerations are common injuries managed by emergency department practitioners and are mostly witnessed in children. These lacerations usually require wound closure, which may result in one of the most unpleasant and painful childhood experiences. The pain can be minimized through topical anesthesia, such as a combination of lidocaine, epinephrine, and tetracaine (LET) and a eutectic mixture of local anesthetics (EMLA). The current study was carried out to demonstrate the efficacy of EMLA and LET in pediatric wound management. A thorough literature search was carried out without any time limitation on five electronic databases, including PubMed, Medline, Web of Science, Embase, and Google Scholar. Relevant studies from these databases and their references were scoured for additional studies. Study quality appraisal and data analysis were conducted using Review Manager software (RevMan 5.4.1). The literature search yielded 1651 articles of which only eight were eligible for inclusion in the present study. A meta-analysis of results from 3 studies showed that LET had a significant pain reduction than the control interventions (SMD: -0.46; 95% CI: -0.69, -0.23: p<0.0001). However, the pooled effect size of data from 3 studies showed EMLA had an insignificant difference with the control interventions (SMD: -0.79; 95% CI: -1.82, -0.24: p = 0.13). Similarly, no significant difference in the number of adverse reactions was reported in either EMLA (OR: 2.31; 95% CI: 0.67, 7.93; p = 0.18) or LET (OR: 0.99; 95% CI: 0.15, 6.50; p = 0.99) Our study suggests that the topical application of EMLA and LET effectively offers pain-free wound management among pediatric patients. However, the interventions are subject to adverse reactions that should be considered when managing the wounds.

Clinical Assessment of Intermittent Fasting With Ketogenic Diet in Glycemic Control and Weight Reduction in Patients With Type II Diabetes Mellitus: A Systematic Review and Meta-Analysis.

Diabetes mellitus (DM) is a global epidemic causing significant morbidity and mortality. The most occurring DM is type 2 diabetes mellitus (T2DM) which has similar symptoms as type 1 diabetes mellitus (T1DM). However, it is less marked, making it difficult to diagnose during the early stages. The management of T2DM is usually based on weight and glycemic control, which can be achieved through dietary interventions such as intermittent fasting (IF) and the ketogenic diet (KD). Therefore, this systematic review and meta-analysis aim to demonstrate the role of IF and KD in glycemic and weight control among patients with T2DM. Two methods, including an electronic database search through ScienceDirect, Google Scholar, PubMed, Scopus, Embase, and Web of Science, and a manual search were used to identify relevant studies published between 2000 and 2022. The search yielded 1299 articles, of which only 12 met the inclusion criteria. In addition, study quality appraisal was performed using Review Manager software (RevMan 5.4.1). The pooled results have shown that IF had a similar effect on HBA1c reduction as control interventions (standardized mean differences [SMD]: 0.36%; 95% CI; -0.37, 1.10; P = 0.33, I2 = 87%). Similarly, an insignificant difference in weight reduction between IF and control interventions was recorded (SMD: -1.05%; 95% CI; -2.29, 0.19; P = 0.10, I2 = 96%). On the other hand, KD significantly reduced body weight compared with control diets (SMD: -1.91 kg; 95% CI; -2.96 kg, -0.85 kg; P = 0.0004, I2 = 96%). Similarly, KD had a better effect on the HBA1c percentage reduction than control diets (SMD: -2.00%; 95% CI; -3.76, -0.25; P = 0.03, I2 = 97%). IF and KD have shown reductions in HBA1c and body weight among patients with T2DM. However, the interventions are subject to side effects and should be used with caution and under the supervision of a health professional.

A Rare Case of Metronidazole Overdose Causing Ventricular Fibrillation.

Ventricular fibrillation is not known as a complication of metronidazole poisoning. Although some arrhythmias have been reported as a complication of metronidazole intake while taking antiarrhythmic medications, most such arrhythmias are possibly related to co-ingestion of drugs with metronidazole as it affects the metabolism of these drugs. In this case, ventricular fibrillation occurred in a young patient without preexisting medical conditions or any other known drug ingestion, which was never been reported before. We present a case of an 18-year-old male brought in by the ambulance service after attempting to end his life by overdosing on metronidazole. While being transported he developed ventricular fibrillation and received an electric shock, which reverted the episode. Laboratory investigations did not show any clear cause that might have precipitated his arrhythmia.

Intracranial Lipoma Extending Extracranially in a Five-Year-Old Patient.

Intracranial lipomas are one of the rarest brain lesions. It is thought to form due to abnormal persistence and differentiation of the meninx. Here we report a unique case of a five-year-old male child with no known chronic medical illnesses and with no history of previous surgeries or allergic problems. He was brought to the pediatric emergency department after having episodes of focal seizures, which lasted only two minutes. On arrival to the emergency department, the child had no neurological deficits or any form of distress. A detailed neurological examination was conducted, and it was normal. Brain CT was requested according to the departmental policy, which showed a well-defined oval shape homogenous fat density in the midline along the falx cerebri at the vertex level, likely representing interhemispheric lipoma. Intracranial lipomas are rare and usually asymptomatic lesions that are formed of adipose tissue. The tumor is usually diagnosed as an incidental finding on CT or MRI scans as patients are usually asymptomatic. However, if symptomatic, the most common presentation of this tumor is seizures. The management is usually conservative, and surgical intervention is not usually recommended.

Bilateral Elbow Dislocation After Trauma in a Healthy Adult Female.

Bilateral elbow dislocation is a rare injury. We report a rare case of a simultaneous bilateral traumatic elbow dislocation in a 28-year-old previously healthy Kenyan female. Initial clinical assessment and plain radiographs showed the possibility of an associated fracture at the right capitulum. CT scan demonstrated bilateral fractures at the capitulum simultaneously. This case was managed conservatively through a closed reduction under procedural sedation as a joint effort of orthopedics and the emergency department. Three days later, the left above elbow backslap was removed and the patient was discharged on analgesics and referred to the outpatient clinic for regular follow-up and physiotherapy. At seven weeks, the patient reported improvement of pain bilaterally and mild stiffness at the right elbow that is continuing to improve with physiotherapy.

Transient Left Bundle Branch Block in the Setting of Cardiogenic Pulmonary Edema.

Cardiogenic pulmonary edema complicated by transient left bundle branch block (LBBB) is a relatively rare finding. We report a case of a 52-year-old woman with underlying heart failure but no structural heart disease who was referred for evaluation due to severe shortness of breath and documented LBBB on a 12-lead EKG. She was diagnosed with cardiogenic pulmonary edema due to medication noncompliance. With the resolution of her symptoms by treating her pulmonary edema with bisoprolol and furosemide, repeated EKG showed resolution of LBBB. A review of her medical records showed similar presentations of pulmonary edema associated with transient LBBB. In conclusion, to the best of our knowledge, transient LBBB associated with cardiogenic pulmonary edema is very uncommon. The etiology of transient LBBB remains unclear, however, the most likely theory that explains our patient's transient LBBB is a consequence of ventricular enlargement from fluid overload and cardiac muscle strain with dilatation, causing bundle conduction interruption. Our patient's cardiogenic pulmonary edema was complicated with transient LBBB in multiple previous presentations with a resolution of the LBBB after treating the underlying pulmonary edema.

Thymus Gland: A Double Edge Sword for Coronaviruses.

The thymus is the main lymphoid organ that regulates the immune and endocrine systems by controlling thymic cell proliferation and differentiation. The gland is a primary lymphoid organ responsible for generating mature T cells into CD4+ or CD8+ single-positive (SP) T cells, contributing to cellular immunity. Regarding humoral immunity, the thymic plasma cells almost exclusively secrete IgG1 and IgG3, the two main complement-fixing effector IgG subclasses. Deformity in the thymus can lead to inflammatory diseases. Hassall's corpuscles' epithelial lining produces thymic stromal lymphopoietin, which induces differentiation of CDs thymocytes into regulatory T cells within the thymus medulla. Thymic B lymphocytes produce immunoglobulins and immunoregulating hormones, including thymosin. Modulation in T cell and naive T cells decrement due to thymus deformity induce alteration in the secretion of various inflammatory factors, resulting in multiple diseases. Influenza virus activates thymic CD4+ CD8+ thymocytes and a large amount of IFNγ. IFNs limit virus spread, enhance macrophages' phagocytosis, and promote the natural killer cell restriction activity against infected cells. Th2 lymphocytes-produced cytokine IL-4 can bind to antiviral INFγ, decreasing the cell susceptibility and downregulating viral receptors. COVID-19 epitopes (S, M, and N proteins) with ≥90% identity to the SARS-CoV sequence have been predicted. These epitopes trigger immunity for antibodies production. Boosting the immune system by improving thymus function can be a therapeutic strategy for preventing virus-related diseases. This review aims to summarize the endocrine-immunoregulatory functions of the thymus and the underlying mechanisms in the prevention of COVID-19.

Emerging trends in the delivery of nanoformulated oxytocin across Blood-Brain barrier.

Neurological diseases are related to the central nervous system disorders and considered as serious cases. Several drugs are used to treat neurological diseases; however, to date the main issue is to design a therapeutic model which can cross the blood-brain-barrier (BBB) easily. The delivery of neuropeptides into the brain lays as one of the important routes for treating neurological disorders. Neuropeptides have been demonstrated as potential therapeutics for neurological disorders. Among numerous neuropeptides, the oxytocin (OT) hormone is of particular interest as it serves as a neurotransmitter in the brain as well as its role as a hormone. OT has a wide-range of activities in the brain and has a key role in cognitive, neuroendocrine, and social functions. However, OT does not cross the BBB readily coupled with its half-life in the blood being too short. The current literature reveals that the delivery of OT by nanoparticle-based drug delivery system (DDS) improves its efficacy. Nanoparticle based DDS are considered important tools for the targeted delivery of drugs to the brain as they lower toxicity of the drug and improve the drug efficacy. Nanoparticles are advantageous candidates for biomedical applications due to their distinctive characteristics such as quantum effects, large surface area and their ability to carry and transport the drug to its target site. OT can be delivered through oral and intranasal routes, but the bioavailability of OT inside the brain can further be enhanced by the delivery using nanoparticles. The application of nano-based delivery system not only improves the penetration of OT inside brain but also increases its half-life by the application of encapsulation and extended release. The aim of current review is to provide an overview of nanoparticle-based drug-delivery systems for the delivery of OT inside brain.

Modeling of the irradiation effect on some physicochemical properties of metoprolol tartrate for safe medical uses.

The effect of gamma-irradiation and ionizing radiation (high-energy electrons beam) on the physicochemical properties of metoprolol tartrate at the solid phase and aqueous solution, has been investigated in the present study to model some properties affected by absorbed doses and to reveal some interesting mutual causal correlation. The proposed some interesting models can be adapted to other experimental conditions, and the newly obtained values of the adjustable parameters could be an excellent criterion of the state quality of the metoprolol tartrate or for other additional interpretations. The peculiar behaviour of variation of physicochemical properties against dose leads us to confirm the suggested optimized doses mentioned in previous work, for sterilization and safe medical uses.

Factors associated with patient delay in accessin pulmonary tuberculosis care, Gezira State, Sudan, 2009.

Analyses of patient delays in seeking treatment for tuberculosis (TB) provide useful evidence for national TB control programmes. The objectives of this study in Gezira State, Sudan were to estimate the extent of, and factors associated with, pulmonary TB patient delay in accessing care. A cross-sectional phase was conducted to determine the length of delay, followed by a nested case-control phase comparing patients delaying above or below the median time. The mean patient delay was 27.2 days, median 4 days (range 0-365 days). There were no significant differences between case and control groups in terms of age, sex, marital status, educational level or smoking status. However, patients living in urban areas, with low income status and who were housewives or unemployed were more likely to delay. Also patients with a history of contact with a TB patient, those who suspected TB and those with a history of chronic obstructive pulmonary disease were more likely to delay.

Factors associated with patient delay in accessing pulmonary tuberculosis care, Gezira State, Sudan, 2009

Analyses of patient delays in seeking treatment for tuberculosis [TB] provide useful evidence for national TB control programmes. The objectives of this study in Gezira State/ Sudan were to estimate the extent of, and factors associated with, pulmonary TB patient delay in accessing care. A cross-sectional phase was conducted to determine the length of delay, followed by a nested case-control phase comparing patients delaying above or below the median time. The mean patient delay was 27.2 days, median 4 days [range 0-365 days]. There were no significant differences between case and control groups in terms of age/ sex, marital status, educational level or smoking status. However, patients living in urban areas, with low income status and who were housewives or unemployed were more likely to delay. Also patients with a history of contact with a TB patient, those who suspected TB and those with a history of chronic obstructive pulmonary disease were more likely to delay

Epidemiology of anaemia among pregnant women in Geizera, central Sudan.

A cross-sectional study was conducted between August and September 2010 at the antenatal care clinic of the Araba Waeshreen Hospital (Geizera), central Sudan. Sociodemographic, medical, obstetric and use of pica information were gathered. Body mass index (BMI) was calculated. Haemoglobin levels were measured and blood films and stools were examined for malaria and schistosomiasis. Out of the 292 women, 119 (40.8%) had anaemia (HB < 11 g/dl); eight (2.7%) had severe anaemia (HB < 7 g/dl). One patient had a positive blood film for malaria. A total of 38 (13.0%) out of the 292 pregnant women had S. mansoni infections. While age, parity, gestational age, education, occupation, interpregnancy interval and BMI were not associated with anaemia, pica (OR = 1.7, 95% CI = 1.0-2.9, p = 0.02) and S. mansoni infections (OR = 2.8, 95% CI = 1.2-6.7, p = 0.01) were significantly associated with anaemia using univariate and multivariate analyses. The high prevalence of anaemia among these women needs to be controlled through preventive measurement of S. mansoni infections and health education to prevent practising pica.
