Central nervous system diseases associated with blood brain barrier breakdown - A Comprehensive update of existing literature

Published on: 25th August, 2020

OCLC Number/Unique Identifier: 8799409922

Blood vessels that supply and feed the central nervous system (CNS) possess unique and exclusive properties, named as blood–brain barrier (BBB). It is responsible for tight regulation of the movement of ions, molecules, and cells between the blood and the brain thereby maintaining controlled chemical composition of the neuronal milieu required for appropriate functioning. It also protects the neural tissue from toxic plasma components, blood cells and pathogens from entering the brain. In this review the importance of BBB and its disruption causing brain pathology and progression to different neurological diseases like Alzheimer’s disease (AD), Parkinson’s disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington’s disease (HD) etc. will be discussed.

Post-stroke dizziness of visual-vestibular cortices origin

Published on: 27th November, 2020

OCLC Number/Unique Identifier: 8799408842

Many patients with chronic cerebrovascular diseases complain “dizziness”, which is a distortion of static gravitational orientation, or an erroneous perception of motion of the sufferer or of the environment. In the vestibular cortical system, the parieto-insular vestibular cortex (PIVC) serves as the core region having the strong interconnections with other vestibular cortical areas and the vestibular brainstem nuclei. By forming the reciprocal inhibitory interactions with the visual cortex (VISC), it also plays a pivotal role in a multisensory mechanism for self-motion perception. In a line of our studies on post-stroke patients, we found that there was a significant decrease in the cerebral blood flow in both the VISC and PIVC in the patients who suffered from dizziness. In this article, we provide a new concept that due to dysfunction of the visual-vestibular interaction loop, low cerebral blood perfusion in the PIVC and VISC might elicit post-stroke dizziness.

Cortical spreading depolarizations in the context of subarachnoid hemorrhage and the role of ketamine

Published on: 23rd March, 2021

OCLC Number/Unique Identifier: 9026724760

Delayed cerebral ischemia (DCI) is one of the main complications of spontaneous subarachnoid haemorrhage and one of its causes is the cortical spreading depolarizations (CSDs). Cortical spreading depolarizations are waves of neuronal and glial depolarizations in which there is loss of neuronal ionic homeostasis with potassium efflux and sodium and calcium influx. In damaged brain areas and brain areas at risk, such as those adjacent to subarachnoid haemorrhage (SAH), CSDs induce microvascular vasoconstriction and, therefore, hypoperfusion and spread of ischemia. Several studies have been devoted to minimize secondary injuries that occur hours to days after an acute insult. Ketamine, a drug until recently contraindicated in the neurosurgical population for potentially causing intracranial hypertension, has re-emerged as a potential neuroprotective agent due to its pharmacodynamic effects at the cellular level. These effects include anti-inflammatory mechanisms, and those of microthrombosis and cell apoptosis controls, and of modulation of brain excitotoxicity and CSDs. A literature review was performed at PubMed covering the period from 2002 to 2019. Retrospective studies confirmed the effects of ketamine on the control of CSDs and, consequently, of DCI in patients with SAH, but did not show improvement in clinical outcome. The influence of ketamine on the occurrence/development of DCI needs to be further confirmed in prospective randomized studies

Characterization of the immune response in neuroimmune disorders in children

Published on: 20th April, 2021

OCLC Number/Unique Identifier: 9026721284

Background: A misguided auto-reactive injury is responsible for several types of central nervous system (CNS) conditions in pediatrics. We propose that, in some of these conditions, the adaptive immune system has a common cellular immune pathogenesis, driven predominantly by T cells, despite variability on the phenotypical clinical presentation. Methods: We have characterized the CD4+/CD8+ adaptive immune response (AIR) on pediatric patients presenting with clinical symptoms compatible with Neuroimmune Disorders (NID). Flow cytometry with deep immunophenotyping of T cells was performed on peripheral blood obtained during the acute clinical phase and compared to an age-matched cohort group (Co). Results: We found that pediatric patients with confirmed NID, exhibit a pattern of dysregulation of CD4+ lineages associated with autoimmune processes. Discussion: The autoimmune associated CD4+ dysregulation was associated with patients with NID, as compared to healthy controls and patients with non-autoimmune diagnoses. If we can improve our capacity for early accurate diagnosis and meaningful disease monitoring of pathogenic T cell subsets, we can both expedite disease detection and may serve as a guide to the administration of effective immunotherapeutic agents.

Five-year follow up on the single level corpectomy

Published on: 27th July, 2021

OCLC Number/Unique Identifier: 9147510496

Single-level Anterior Cervical Decompression and Fusion (ACDF) was initially performed using Iliac Crest Bone Graft (ICBG) [1]. Fusion rates improved when a surgical technique change, the addition of anterior plate fixation, was incorporated decades later [2,3]. Single level ACDFs with a machined allograft and plate fixation technique eventually became the industry standard as it demonstrated equivalent fusion rates with fewer complications than single level ACDFs with ICBG. This surgical technique was extended for use in patients with contiguous disk herniations. Multilevel ACDFs performed with machined allografts or interbody spacers and a two-level plate offered shorter operative times, less blood loss, better restoration of lordosis, and less immediate pain [4]. Successful multi-level ACDFs were strongly influenced by the bone graft source [5], the smoking addiction [6], and the construct stability [7]. Placement of two additional fixation screws in the central vertebral body, another improvement in the surgical technique, increased the construct strength compared to constructs with screws only placed into the end vertebral bodies [8]. Using allografts for multilevel ACDFs was a device disadvantage as they often resulted in high non-union rates [9,10].

Sleep quality and associated factors among patients with chronic illness at South Wollo Zone Public Hospitals, Northeast Ethiopia

Published on: 20th July, 2021

OCLC Number/Unique Identifier: 9186943722

Background: Pathological and nighttime sleep deprivations have substantial adverse effects on regulation of weight, sugar and blood pressure because of endothelial dysfunction, sympathetic nervous system stimulation, regulation and activation of systemic inflammation. Thus, this study was aimed to assess quality of sleep among patients with chronic illness and its associated factors at South Wollo Zone Public Hospitals, Northeast Ethiopia. Methods and Materials: The study was conducted at South Wollo Zone Public Hospitals, Northeast Ethiopia from February 15 2019 till April 15 2019. Institutional based cross sectional study design was employed. All patients with chronic illness who are on follow up in South Wollo Zone Public Hospitals were sources of population. Sample size was calculated by using EPI info version 7 and the total sample size was 344. The study employed stratified random sampling technique and study participants were selected by systematic sampling. After taking ethical approval from College of Medicine and Health Sciences Ethical Approval Committee, permission from selected Hospitals and informed verbal consent from patients, the data were collected by a tool which has 3 parts: Sociodemographic data, Pittsburgh Sleep Quality Index and factors affecting sleep quality. Data were entered in to Epi data version 4.1 and exported to Statistical Package for Service Product 25 for analysis. Different data presentation tools and binary logistic regression were enrolled by considering 95% confidence level and p value of 0.05. Result: Among the total study participants, near to one third (31.7%) of them got sleep after 30 minutes. More than one fourth of them slept for less than 7 hours. Less than half of the study participants had habitual sleep efficiency of more than 85% however 296(86%) of them did not face day time dysfunction Conclusion and recommendations: more than one third of patients with chronic illness had poor sleep quality. One third of study participants had sleep duration of less than the recommendations(less than 7 hours). Age, educational status, residence, and perception of prognosis of disease were factors that have associations with poor sleep quality among patients with chronic illness. Health care providers who are doing in chronic illness follow up clinic should be initiated to assess and screen those patients with poor sleep quality.

Application and utility of alternative methods in isolation of pure cells from forensic biological mixtures in modern-day: a review

Published on: 23rd August, 2021

OCLC Number/Unique Identifier: 9206128467

Development of genetic profiles from the biological mixtures has remained challenging, although modern-day technologies may help forensic scientists to attain a reliable genetic profile in the identification of the accused. In the case of rape, vaginal swab exhibits usually contain epithelial cells of victims and sperm cells of accused, such samples are more challenging when there is more than one contributor. In such cases, separation of distinct cells from a mixture that includes blood cells, epithelial cells and sperm cells for their single genetic profile is important. In the last ten decades several new techniques were developed and invented for the separation of single cell from the biological mixture that includes differential lysis, laser micro-dissection, cell sorting (FACS), sieve-based filtration, (vi) micro-fluidic devices or immunomagnetic beads cell separation of fresh samples, and the magnetic activated cell sorting (MACS). Out of them, some techniques have been commonly applied for cell separation in forensic biology. Each technique has its own limitation. Some recent studies showed, magnetic activated cell sorting (MACS), laser capture microdissection (LCM), DEPArray technology and fluorescence activated cell sorting (FACS) has proved to be effective in separation of single cell from cell mixtures. Therefore, in this review we have evaluated these four alternative methods and their potential application in the modern-day over the others for the separation of a single cell from the mixture. In this review we also discuss the advantage of these methods and their modern–day applicability and acceptance in the forensic world.

Victim of violent death: what is the role of alcoholemia?

Published on: 25th August, 2021

OCLC Number/Unique Identifier: 9206121369

Introduction: The tendency to impulsive behaviors and/or violence is exacerbated after alcohol consumption. Still, the relation between alcohol/violent deaths reported in the literature is not accurate, and in general, alcohol is only seen as a trigger to aggressive actions. The relationship of the victims with their blood alcohol is less studied. They were especially concerned about the role of alcohol as a risk factor for victims of unnatural death. Thus, our goal is to check the influence of alcohol in victims of violent deaths as homicides, suicides, and accidents. Materials and methods: Retrospectively the medical records of 805 autopsies performed at the Institute of Forensic Medicine (IML) of Franco da Rocha, in the period 2001 to 2017 were reviewed. The variables studied were sex, age, types of violent death rates, and alcohol - these were considered positive when above 0.3 mg/ml. The dosage of blood alcohol concentration (BAC) was performed using samples of 10 ml of blood collected at necropsy, is preferably taken from the cardiac chambers or of the right femoral vein. Dosages of alcohol in blood samples were done in the Forensic Toxicology Center of the IML by gas chromatography, using the technique of separation “headspace” and double column. Results: Drug testing for alcohol was available for 488 (79.1%) of 617 necropsies. Of the 617 subjects studied, 532 (85.7%) were male, and 85 (13.8%) were females (with high rates of adolescents). The vast majority (n = 230) were killed, and 40.5% of victims had BAC above 0.3 mg/ml of blood. Traffic accidents came next, accounting for 181 deaths, with 41% of victims presenting positive BAC. Discussion: High blood alcohol levels of the victims were associated mainly with the genesis of accidents (drowning, falls, traffic, aspiration/ smothering) and murder (with impaired ability to resist or by causing the release of impulses to engage in violent situations), about 40% of cases. Conclusion: Our results indicate that alcohol abuse is a risk factor for victims of violent death. In these cases, alcohol has two types of action. Direct: contributes to accidents of various kinds - from traffic by decreasing powers of concentration, attention, and loss of reflexes, to other types of accidents such as drowning, falls, swallowing disorders causing airway obstruction, and mechanical asphyxia. And they were indirect, making it easier for individuals to engage in conflict (and thus become victims of crimes).

Contemplating SARS-CoV-2 infectivity with respect to ABO blood groups

Published on: 26th October, 2021

OCLC Number/Unique Identifier: 9322470952

COVID-19 is a disease that is caused by SARS-CoV-2 and very speedily spreading all over the world. The blood group’s effect on COVID-19 is not clear. The main aim of this article is to determine the relationship between sensitivity of COVID-19 and ABO blood group. For this study we have observed that the individuals with blood group A are at higher risk of getting COVID-19 because they contain the higher concentration of Angiotensin-converting enzyme-2 that provide the site to virus for entry. But in other blood groups the natural Anti A antibodies block the interaction between host receptor and virus and disturb their interaction. Certain studies show that the infectivity and mortality rate in covid patients is not affected by AB blood group system. But according to research, increased ventilator usage, ICU stay was observed in critically ill patients with AB blood group than of other blood groups. O blood group has proved to be protective against SARS-CoV-2 due to the presence of both anti-A and anti-B antibodies as they prevent the binding of the spike protein S of the virus with the ACE2 receptors which are present on the surface of cells. Moreover, furin also plays a major role in penetration of virus in the host cells. Furin is required for the activation of the spike protein S of the virus and due to the low efficiency of furin cleavage in blood group O it is protected from SARS-CoV-2 and other chronic diseases. Mortality rate of covid 19 depends upon the environmental factors, number of people living in the area and also some economic factors. The different strains of COVID-19 effect the different people differently and as the time passes the strain of COVID-19 has changed and thus according to this the mortality rate of different provinces and areas varies due to environmental factors. Pregnant women have no any kind of transportation of covid to their fetuses but mostly patients of blood group A are being affected by COVID-19 and hence their fetuses are somehow effected. And those pregnant women having blood group O does not have any risk of COVID-19 of severe stages.

Published on: 28th October, 2021

OCLC Number/Unique Identifier: 9322406717

Background: The survival of people living with HIV (PLWHIVs) is increased and Health systems will have to deal with the early-aging-associated medical conditions.Objective: The objective of this study is to compare the clinical and biological profiles of PLWHIVs aged 50 and over and those aged less than 50 years.Material and methods: This study conducted at Kinshasa University Teaching Hospital (KUTH) covers 6 years. The clinical and biological characteristics of PLWHIVs aged 50 and over were compared with those under 50. Statistical analysis used the means ± SD, the calculation of frequencies, Student’s t-test and Chi-square.Results: PLWHIVs aged 50 or over represented 35.1%. Their average age was 58.0 ± 4.8 years. Women predominate among those under 50 and men among those 50 and over. Married people were more numerous (54% among those under 50). There were more unemployed (50% of PLHIV under 50). Patients 50 years and older were significantly classified as WHO stage 4 with a high frequency of history of tuberculosis, genital herpes, high blood pressure, smoking, vomiting, hepatomegaly, moderate elevation of diastolic blood pressure (DBP) and sytolic blood pressure (SBP), tuberculosis and anemia.Those under 50 had a significantly increased frequency of shingles, hepatitis B-hepatitis C, headaches and more survivals. The mean of Hb, HDL-C, and CD4s+ were significantly lower in patients 50 years and older, and urea, LDL-c, and ALAT levels were significantly higher. Conclusion: The average age was higher from 50 years old. These PLWHIVs were more frequently in WHO stage 4 with more common TB and anemia. Their Hb, HDL-C, and CD4s+ levels were lower while their urea, LDL-C and ALAT levels were significantly elevated.

A study to correlate the central corneal thickness to the severity of diabetic retinopathy and HbA1c levels in type 2 diabetes mellitus

Published on: 14th December, 2021

Background: Diabetic retinopathy (DR) is one of the most common causes of preventable blindness. Patients with Diabetes Mellitus (DM) develop not only DR but also corneal endothelial damage leading to anatomical and physiological changes in cornea. Central corneal thickness (CCT) is a key parameter of refractive surgery and Intraocular pressure (IOP) estimation. The role of CCT and higher glycemic index in DR needs to be researched upon.Objectives: To identify the corneal endothelial morphology in patients with type 2 DM, to measure the Central Corneal thickness (CCT) in patients with type 2 Diabetes Mellitus, to assess the relationship of CCT with HbA1C levels in the study group and to correlate the CCT with the severity of Diabetic retinopathy in the study group.Methods: A cross-sectional observational study was conducted between January 2018 and June 2019 in Vydehi Institute of Medical Sciences and Research Centre, Bangalore. The study included 100 subjects with type 2 DM for 5 years or more. Patients with comorbidities that may affect the severity of DR or alter CCT and other corneal endothelial parameters such as glaucoma, previous ocular surgery or trauma, corneal degenerations and dystrophies, chronic kidney disease and Hypertension were excluded. DR was assessed by dilated fundoscopy, fundus photography and optical coherence imaging of the macula and graded as per the Early Treatment of Diabetic Retinopathy Study (ETDRS) classification. CCT and other corneal endothelial parameters were measured through specular microscopy. Relevant blood investigations including blood sugar levels were done for all patients.Statistical analysis: Relationship between CCT and grades of DR and HbA1c levels were established using the Chi-Square test. The level of significance was set at p < 0.05.Results: The mean CCT in patients with no diabetic retinopathy, very mild and mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe and very severe NPDR and PDR was 526.62 ± 8.084 μm, 542.07 ± 8.713 μm, 562.16 ± 8.255 μm, 582.79 ± 7.368 μm and 610.43 ± 18.256 μm respectively. Analysis of the relationship between CCT and severity of DR showed a statistically significant positive correlation between the two parameters (Pearson r = 0.933, p = 0.001). Beyond this, a correlation was found between all the corneal endothelial parameters and severity of DR. Multivariate analysis showed that advanced DR was positively correlated with CV (r  = 0.917) and CCT (r = 0.933); while it was negatively correlated with ECD (r = -0.872) and Hex (r = -0.811). A statistically significant correlation was also found between CCT and HbA1c. Also increasing age, duration of DM and higher glycemic index were positively correlated with severity of DR. Conclusion: This study, by demonstrating a strong correlation between the central corneal thickness to the severity of DR and HbA1c levels emphasizes the importance of evaluation of corneal endothelial morphology in the early screening and diagnosis of microvascular complications of DM.

Extraction of DNA from face mask recovered from a kidnapping scene

Published on: 7th January, 2022

OCLC Number/Unique Identifier: 9395237994

Deoxyribonucleic acid (DNA) extraction has considerably evolved since it was initially performed back in 1869. It is the first step required for many of the available downstream applications used in the field of molecular biology and forensic science. Blood samples is one of the main body fluid used to obtain DNA. This experiment used other body fluids such as saliva, sweat tears and mucus. There are many different protocols available to perform nucleic acid extraction on such samples. These methods vary from very basic manual protocols to more sophisticated methods included in automated DNA extraction protocols. This experiment used extraction kit (Zymo research). The DNA result from isolated saliva samples on the facemask range from 133.7, 213.6, 599.1 and 209.1 mg/ml. theoretically; such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 707.7, 202.5, 99.2, and 62.6 mg/ml. Theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 615.3, 66.2, 78.5, and 68.2 mg/ml. theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. Extracted DNA from saliva and sweat produced visible bands on agarose gel, mucous stain produce obscure band on agarose gel and the tears stain produce invisible bands. DNA from sweat satin, saliva stain, mucus stain and tears stain in face mask can be used as alternative for forensic investigation.

Effect of fresh red grape juice and grape fermentative product on oxidative-stress in human erythrocytes in vitro

Published on: 26th January, 2022

OCLC Number/Unique Identifier: 9403421666

Introduction: Oxidative stress is a phenomenon induced by an imbalance between production and the biological system's ability to readily detoxify oxygen reactive species (ROS) in cells. It has been shown that grape juice can reduce oxidative stress due to the presence of polyphenols. The aim of this study was to evaluate the effect of fresh red grape juice and grape fermentative product on oxidative stress in human erythrocytes.Methods: 5 ml of blood from 125 healthy individuals as control group collected in EDTA containing tubes. To perform biochemical assays, erythrocytes were incubated at 37 ºC for different times including 4, 24, 48, and 72 hours in the presence or absence of grape juice and grape red wine in amounts of 5 ml. Results: Grape juice and grape red wine reduced lipid peroxidation and increase of thiol groups, and total antioxidant capacity after 24 hours of treatment (p < 0.05). Also, the activity of catalase enzyme was increased 4 and 24 hours after treatment with red wine and grape juice, respectively. Conclusion: Grape juice and grape fermentative product may improve the antioxidant power of erythrocytes. This may lead to reducing the risk of free-radical damage and chronic diseases. However, more research with a higher number of samples is necessary to confirm the antioxidant effect of grape juice and red wine on human erythrocytes.

To compare serum Vitamin D status in pre-eclamptic and non-preeclamptic pregnant women in labour: A tertiary care centre study of Northern India

Published on: 28th January, 2022

OCLC Number/Unique Identifier: 9406533422

Background: Pre-eclampsia and eclampsia have remained a major global public health threat in contributing significantly to maternal and perinatal morbidity and mortality. Based on the inverse relationship between serum 1,25(OH)2D3 levels and plasma renin activity found previously, it is speculated that 1,25(OH)2D3 might be a negative endocrine regulator of renin production in vivo. During pregnancy, vitamin D may play a role in implantation and placental function potentially due to angiogenic, immunomodulatory, and antiinflammatory effects. Vitamin Ddeficiency can affect the health of both mother and fetus by increasing the production of inflammatory cytokines and stimulating the activity of T-regulating cells. Vitamin D is emerging as a promising agent for pre-eclampsia prevention. Aims and objectives: The objective of this study is to compare the vitamin D levels in pre-eclamptic and healthy non-pre-eclamptic pregnant women in labor and find out the relationship between vitamin D levels and pre-eclampsia. Methodology: The present cross-sectional study was carried out on pregnant women with pre-eclampsia in labor. For each case with pre-eclampsia, one uncomplicated, normotensive pregnant woman in labor was taken as control. On admission to the labor room detailed history, physical examination followed by thorough obstetrics and systemic examination was done. Required investigations were done including vitamin D and calcium levels. Maternal and fetal condition was monitored during labor/cesarean section, mode of delivery, maternal and fetal outcomes were recorded. After delivery, 2cc of cord blood was collected in a serum tube and sent for vitamin D levels. Data was collected and analyzed statistically using Epi-info version 7.1.Results: It was observed that the patients in both groups were comparable with respect to demographic and obstetrics characteristics except for significantly high BP in group I. Vitamin Ddeficiency (i.e. < 20 ng/ml) was significantly more in group I as compared to group II and the difference was highly significant (p < 0.0001). Similarly, the mean maternal calcium levels were significantly lower in group I in comparison to group II (p < 0.0001) i.e. the mean maternal calcium level in group I and group II were 8.03 ± 0.94 and 9.19 ± 0.67 respectively. It was also observed that the level of 25-OH-D in neonates of preeclamptic women was significantly lower than for those of the normal pregnant women (p < 0.0001). Conclusion: Vitamin D deficiency is highly prevalent in all parts of the world. Pregnant women and neonates are highly vulnerable to vitamin D deficiency. Preeclampsia is indeed associated with lower vitamin D levels and the pathophysiology of pre-eclampsia involves vitamin D and calcium metabolism through their role in immunomodulation, angiogenesis and anti-inflammatory effects. From the present study, it was observed that vitamin D and calcium levels were significantly lowered in women with pre-eclampsia as compared to those of the normotensive pregnant women. So early detection of vitamin D and calcium deficiencies may be helpful in preventing occurrence of PET and its complications.

Ceftriaxone in pediatrics: Indication, adverse drug reaction, contraindication and drug interaction

Published on: 5th April, 2022

OCLC Number/Unique Identifier: 9470678055

Ceftriaxone is having many uses and useful “third-generation” cephalosporin that necessitates being given every day. Ceftriaxone acts as binds to one or many of the penicillin-binding proteins which inhibit the final transpeptidoglycan step of peptidoglycan synthesis in the bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.Ceftriaxone-associated biliary adverse events in children less than eighteen years cause biliary pseudolithiasis and scarcely nephrolithiasis often happen in children less than eighteen years after receiving overdoses of ceftriaxone. Ceftriaxone perhaps binds with calcium and figure insoluble chelation leading to biliary pseudolithiasis. Cholelithiasis, increased biliary thickness, and pseudolithiasis rarely happen in a period of being a child, but there are two modes of distribu¬tion described by two peaks, the first being at an early stage of development and the second is a period of life when a child develops into an adult. Hyperbilirubinemia is significantly contraindicated for neonates administrated ceftriaxone, particularly premature neonates, because of the displacement of bilirubin from albumin-binding sites and increase in blood concentrations of free bilirubin. A child than one month old and a child less than twelve-month old in special are at great risk of poor results because of bilirubin encephalopathy. Coincident administrations of ceftriaxone with aminoglycosides such as gentamycin and loop diuretics (furosemide) perhaps increase the risk of nephrotoxicity (rapid degeneration in the kidney function to the toxic outcome of double or triple medications). Coincident administrations of ceftriaxone with anticoagulant medications such as warfarin are associated with bleeding due to increased prothrombin times, which is reversible with vitamin K.

Review on epidemiology of bovine hemoparasites in Ethiopia

Published on: 29th April, 2022

A literature-based review was made to assess available information on bovine hemoparasites related to their epidemiology, distribution, and economic importance in Ethiopia. Babesiosis, anaplasmosis, cowdriosis, theileriosis, and trypanosomosis are the major hemo-parasitic disease of bovine in Ethiopia. Their adverse effects on the health of the animals can decrease production and productivity. Hemoparasites generally cause fever, anemia, jaundice, anorexia, weight loss, milk drop, malaise, swelling of lymph nodes, dyspnoea, diarrhea, nervous disorders, and death by affecting blood vessels and/or lymphatic system of the animal. Reports from different parts of the country displayed there is a high distribution of bovine hemoparastic disease throughout the country. Anaplasmosis, Babesiosis (redwater), Ehlichiosis (Heartwater), Theileriosis, and Trypanosomosis are the major hemoparasitic diseases with heavy economic losses. Their mode of transmission was by arthropod vectors ticks and flies. Applying effective vector control and using vaccines drugs are the two most important control methods for hemoparasites diseases. Also having knowledge of parasite life cycles, their biological vector, and the immune response of bovines to vectors and parasites were also used in the successful application of control strategies. Creating awareness of the mode of transmission, method of control, and prevention of hemoparastic disease of bovine to livestock owners were warranted to decrease the effect of the disease.

Antimycolytic agents: fungistatic and fungicide

Published on: 6th May, 2022

Invasive fungal infections are described as a continuous and severe harm to human health and they are associated with at least 1.5 million deaths worldwide each year. Amphotericin B exerts its activity through hydrophobic interactions with cell membrane ergosterol, cause the rupturing or leakage of cell membrane. The antifungal azole medicine group is classified as imidazoles (clotrimazole, ketoconazole, miconazole) and triazoles (fluconazole, itraconazole, voriconazole, posaconazole, isavuconazole) that are named according to the number of nitrogen atoms in the azole ring. Flucytosine is a first-line treatment for the management of cryptococcal meningitis. The most routine adverse effects of fluconazole involve accelerated liver enzymes, gastrointestinal complaints, headache, and skin rash. If antacids, PPIs, H2 blockers administered together with ketoconazole medicines; they will reduce the blood levels of ketoconazole by increasing gastric pH because ketoconazole requires an acidic media for dissolution and systematic absorption. Griseofulvin ruptures mitotic spindle during metaphase by interacting with fungal microtubules-(-), fungal mitosis (metaphase arrest), adequate to block expansion of fungi (drug is static), preventing them from damaging.

A witnessed intra-operative blood transfusion-related air embolism under epidural anaesthesia for vesicovaginal fistula repair

Published on: 21st June, 2022

OCLC Number/Unique Identifier: 9554643394

The transfusion is a normal life-saving procedure conducted commonly by the nurses at the prescription of the attending physician or the emergency physicians. It is generally a safe procedure if guidelines for processing and administering are carefully followed. Blood transfusion is an independent risk factor for morbidity and mortality and major complications arising from transfusion are generally rare. We present a case of a mild case of iatrogenic air embolism exacerbated by pressure infusion for a patient who had undergone an exploratory laparotomy for an iatrogenic fistula repair under epidural anesthesia.

Can infants develop meningitis in the absence of bacteremia in the first ninety days of life? A retrospective chart review

Published on: 4th July, 2022

OCLC Number/Unique Identifier: 9554569888

The overall incidence of meningitis in infants 0-90 days is low; however, it remains a serious cause of morbidity and mortality among affected patients. It is standard of care to perform lumbar punctures as part of the work-up of fever in the first four weeks of life and sick-looking babies up to the age of 90 days. This particular procedure is often refused by parents, and physicians are left to predict the possibility of meningitis based on blood culture results.The aim of this study is to determine whether it would be safe to rule out meningitis based on a negative blood culture in this age group.
