A 61-year-old Brazilian black woman consulted with a nephrologist due to proteinuria identified on a routine urine test. She has a personal history of thymoma resection five years ago, followed by multiple episodes of pulmonary infections including mycobacteriosis, recurrent mucocutaneous candidiasis, and paraneoplastic pemphigus. Physical examination showed no edema or hypertension and laboratory tests identified proteinuria of 2.43 g/day without hematuria, serum creatinine of 0.69 mg/dl, urea 34 mg/dl, serum albumin of 2.4 g/dl, hemoglobin 10.9 g/dl, platelets 292,000/mm3, leukocytes 4950/mm3, lymphocytes 594/mm3 and neutrophils 3910/mm3. The hemolysis tests were negative and serum iron was low. Analysis of glicemia and serum lipids levels were normal as well as serum complement and imunoglobulins, except for an IgM level of 283 mg/dl (normal values 40 to 230 mg/dl) and undetectable IgE. Serologies for Syphilis, HIV, hepatitis B, C and antibodies for autoimmune diseases were negative.

Introduction: Acute kidney injury (AKI) is one of the complications associated with severe COVID-19 infection, and it can present in up to 20% to 40% of the cases; of these, approximately 20% will require renal replacement therapy (RRT).
Objective: To establish clinical and laboratory characteristics in a group of patients from Colombia with COVID-19 infection and AKI that received intermittent and prolonged RRT with the GENIUS® 90 technology in between March and July 2020.
Design: Cross-sectional study.
Results: 78.9% of participants were men and 21.1% were women. The main comorbidities were the following: Hypertension (65.3%), diabetes mellitus (38.9%), obesity (26.3%), cancer (5.3%), Chronic obstructive pulmonary disease (11.6%), cardiovascular disease (23.2%), active smoking (11.6%). 33.7% had chronic kidney disease (CKD) in the average serum creatinine on admission was 4.4 mg/dl.
The following inflammatory markers were elevated: C-reactive protein (CRP), d-dimer and ferritin (20.3 mg/dl, 931mcg/l and 1174 ng/ml, respectively). 63.5% of patients underwent sustained low-efficiency dialysis (SLED) (6 to 12 hours) and the rest of the patients (36.35%) underwent conventional hemodialysis (less than 4 hours). The mortality of the total patient sample was 36.9%, lower in patients with CKD than in patients with no previous renal disease history (18.7% and 40.1%, respectively).
Conclusion: Renal complications are frequent in patients with severe COVID-19. The development of AKI could be an isolated prognostic marker associated with an increase in mortality in patients with COVID-19, and one of the options is intermittent and prolonged RRT with the GENIUS® 90 system.
Frequency of renal tubular acidosis in children with down syndrome
Published on: 2nd October, 2020
OCLC Number/Unique Identifier: 8691889815
Background: Down syndrome (DS) is associated with various congenital diseases and malformations, including those of the kidneys and urinary tract. It has been thought that renal tubular acidosis (RTA) is more frequent in this population. The objective of this study was to assess the frequency of RTA and, secondarily, of other renal and urological disorders in persons with DS.
Method: An observational, ambispective, descriptive and cross-sectional study of patients diagnosed with RTA, or suspected kidney or urological disorders, was carried out from July 2016 to September 2017 at the Down syndrome clinic of the Mexican National Institute of Paediatrics. Urinalysis was performed, along with analyses of venous blood gas, sodium, potassium, chlorine, calcium, phosphorus, albumin and creatinine. Those with any abnormal values were referred to nephrology for diagnostic evaluation.
Results: Of a total of 700 patients seen at the clinic, 47 met the selection criteria. Of these, 32 had no RTA or other renal or urological alterations. The remaining 15 continued to the second phase of the study, where 6 were diagnosed with nephropathy or uropathy (RTA, systemic arterial hypertension, monosymptomatic familial haematuria, mild renal failure secondary to reflux nephropathy, urinary tract infection or right ureteropelvic stenosis). Four had mild metabolic acidosis without meeting the criteria for diagnosis of RTA.
Conclusion: RTA is not more common in children with Down syndrome. Nephropathies and uropathies should be investigated in the evaluation of DS patients.
Prognostic factors for chronic kidney disease and end-stage renal disease in patients with lupus nephritis: A retrospective cohort study
Published on: 27th April, 2021
OCLC Number/Unique Identifier: 9022387289
Background: Lupus Nephritis (LN) occurs in approximately half of all patients with Systemic Lupus Erythematosus (SLE) and it is the most common cause of morbidity and mortality in patients with SLE. Factors associated with poor renal outcome vary among studies, and researches coming from Brazil are scarce.
Objectives: To identify the prognostic factors associated to the development of Chronic Kidney Disease (CKD) and End Stage Renal Disease (ESRD) in LN patients followed in a tertiary hospital.
Design and Settings: We conducted a retrospective cohort study set in a tertiary hospital in Fortaleza, Ceará, Brazil. Methods: We compiled a total of 214 LN patients diagnosed between 1983 and 2015. Data was collected from medical records and further analyzed using logistic regression.
Results: LN prevalence was 53.9%. The cohort had a mean follow-up of 11.2 years (SD ± 7.2 years). At the end of follow-up, 93 of 197 patients (47.2%) had CKD, and 49 of 191 (25.6%) were on regular dialysis. The main factors associated for developing CKD after logistic regression analysis were the following predictors: hypertension (HR 2.80; 95% CI 1.30-6.01; p = 0.008), time between diagnosis of SLE and diagnosis of LN (HR 0.98; 95% CI 0.97-0.99; p = 0.009) and discontinuation of medications (HR 2.41; 95% CI 1.08-5.37; p = 0.03).
Conclusion: Hypertension, discontinuation of medications, and time between diagnosis of SLE and diagnosis of LN are independent variables associated with the development of CKD and ESDR in our study.
Acute Kidney Injury due to spontaneous Atheroembolic disease, superimposed on diabetic nephropathy, with no recent vascular or cardiac intervention, presented as Rapidly Progressive Glomerulonephritis (RPGN)
Published on: 14th July, 2021
Atheroembolic disease (AED), or Cholesterol Crystals Embolism, is a systemic disease presented as a complication of severe atherosclerosis [1], where older age, male sex, diabetes hypercholesterolemia, smoking and hypertension [2], are the main risk factors for the development of Atherosclerosis, it is known that spontaneous atherosclerotic renal disease is rare in the absence of any vascular intervention [3], and in the absence of anticoagulant [4], or the absence of calcified aorta, with the most common presentation of the disease is subacute kidney injury progress into renal dysfunction occurs in like a staircase pattern and the renal dysfunction is usually observed several weeks after a possible intervention, caused by dislodging the micro cholesterol plaques from a major artery, and start showering multiple organs causing micro and macro embolic phenomena.
In our case, we report acute kidney injury on a previously stable kidney disease in a female with diabetes mellitus type 2 presented with severe anemia, dyspnea, massive fluid overload with bilateral pleural effusion, patient had a history of multiple IV contrast exposures, with peripheral vascular occlusive disease (PVOD), required amputation of right below the knee amputation, presented during the COVID-19 pandemic, found with nephrotic syndrome, a kidney biopsy has shown cholesterol crystal embolization compatible with Athero-embolic Disease with severe Diabetic Nephropathy.
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
Stiff “Left Atrial” syndrome post-mustard procedure
Published on: 1st December, 2021
OCLC Number/Unique Identifier: 9359567131
Objectives: We describe the clinical course and management of two patients with post-capillary pulmonary hypertension due to diffuse pulmonary venous baffle calcification decades post-Mustard procedure.Background: From the late 1950s to the early 1990s, the definitive surgical repair for children with D-transposition of the great vessels (D-TGA) was an atrial switch procedure (either Senning or Mustard operation) which utilizes atrial-level baffles to shunt pulmonary venous blood to the morphologic right (systemic) ventricle and caval blood to the morphologic left (sub-pulmonary) ventricle. From a hemodynamic standpoint, baffle leaks and stenoses as well as precapillary pulmonary hypertension have all been described as both early and late complications [1]. Recently, delayed post-capillary pulmonary hypertension (in the absence of discrete baffle obstruction) decades post-atrial switch has also been described [2]. The underlying pathophysiology for this postcapillary pulmonary hypertension is unclear but is theorized to involve impaired diastology referable to the pulmonary venous baffle. Methods/Results: Using hemodynamic and imaging data, we describe two patients with extensive pulmonary venous baffle calcification and resultant pulmonary hypertension from the so-called “stiff left atrial (LA) syndrome.” This problem can be difficult to treat medically and is not amenable to catheter-based interventions. We hypothesize that this is an underlying mechanism for pulmonary hypertension in at least some post-Mustard and Senning patients. Conclusion: We describe the treatments and clinical course for each of these patients, and in particular describe how the surgical revision of the pulmonary venous baffle in one case led to the complete resolution of symptoms.
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.

Published on: 3rd January, 2022
OCLC Number/Unique Identifier: 9396216057
Background and objectives: Brainstem gliomas are tumors of the central nervous system which have varying presentations and clinical courses. This study aims to analyze the frequency, clinical and therapeutic aspects of brainstem glioma.Methods: We retrospectively analyzed the data from the record of the patients treated for brainstem glioma under the age of 20 between January 2007 and July 2020 in the Radiation Oncology department of the Ibn Rochd UHC.Results: There were fifteen patients (10 males and 5 females). The mean age of onset was 12 years (range 8 - 14 years). The duration of symptoms varied from 1 month to 2 years. Nine of the patients had intracranial hypertension due to hydrocephalus, six had cranial nerve deficits at presentation, and five patients had cerebellar signs. The lesion was pontine in 12 cases. None of the patients had a tumoral resection, nine had a ventriculo-peritoneal shunt insertion for the hydrocephalus and three had a Stereotactic biopsy that revealed one astrocytoma grade 1, one low grade glioma and one glioblastoma. The radiotherapy was indicated in all the cases but only nine patients had a 3D radiotherapy with a total dose of 54 Gy. Three patients received chemotherapy. Six patients are still alive, two are lost to follow up and seven patients are dead with a mean survival period of 8 months.Conclusion: Brainstem glioma is a devastating disease with a bad prognosis. The clinical presentation is variable and the management is multidisciplinary. Our study illustrates the importance of treatment by radiation.
Age, smoking, hypertension, and aortic aneurysm: Interactions and risks
Published on: 6th January, 2022
OCLC Number/Unique Identifier: 9391753907
Background/Aim: Aortic aneurysm is the bulging of a weakened portion of the aorta. The aorta is the major blood vessel that feeds blood (carrying oxygen, nutrients and water) to the tissues of the body. When a portion of the wall of the aorta becomes weak, blood pushing against the vessel wall can cause it to bulge like a balloon (aneurysm) leading to aortic dissection (a tear in the wall of the aorta that can cause life-threatening bleeding or sudden death). Blood pressure is the force arterial blood exerts on the wall of the artery. When this pressure is consistently high above 140/100 mmHg it is referred to as hypertension. As an individual gets older over time, physiological functions of the body depreciate leading to some abnormalities. Smoking is the consumption of tobacco mostly by inhalation of the smoke that is produced from burning the tobacco. This review article examines the close interactions between age, smoking, hypertension and aortic aneurysm, with a view to understanding mechanisms by which these factors predispose a patient to an aortic aneurism. It is also to observe if these factors interfere with treatment and recovery from aneurysms. Conclusion: After careful review, it is observed that age and smoking are risk factors for hypertension, and together with hypertension, the three factors predispose an individual to high risk for aortic aneurysm.
Lifestyle modification practice and associated factors among diagnosed hypertensive patients in selected Hospitals in West Arsi Zone, Oromia Regional State, Ethiopia
Published on: 1st February, 2022
Background: Globally 1.13 billion people were living with hypertension, Out of this two-thirds of them were living in low and middle-income countries. In Ethiopia, Non-Communicable Disease deaths are estimated at around 42%. However, it remains widely undetected and poorly controlled. To resolve these, lifestyle modification approaches that are often overlooked are the cornerstone of the prevention and management of hypertension. Objective: To assess lifestyle modification practice and associated factors among hypertensive patients in selected hospitals in West Arsi Zone, Oromia Regional, Ethiopia December 7 to 21, 2019. Method: Hospital-based cross-sectional study was conducted in the selected public hospital among 299 hypertensive patients. Systemic random sampling methods were used to select the study participants. Data were collected by face-to-face interviews using a structured questionnaire by trained data collectors. Data were analyzed using descriptive statistics and multivariate logistic regression method to identify predictors of the outcome (p < 0.05). Results: Of the total participants, only 25.2% (95% CI: 18.8-32.9) of the patients were practiced recommended lifestyle modifications. Patients Age older than 65 years (AOR = 2.9, 95% CI: 1.17 - 7.0), the patients with 2-5 years’ time since diagnosed hypertension (AOR = 0.26, 95% CI: 0.07 - 0.9), multiple co-morbidity (AOR = 2.7, 95% CI: 1.25 - 5.8,) and their knowledge on hypertension management (AOR = 14.6, 95% CI: 4.6 - 45.9) have an independently associated with recommended lifestyle modification. Conclusion: Lifestyle modification practices among hypertensive patients were low in this study. Age, comorbidity, time since diagnoses of hypertension, and knowledge of lifestyle were identified as predictors of the outcome.
Journey with a 21 weeks primi with acute massive pulmonary thromboembolism secondary to possible “Latent Lupus”: an audacious ride
Published on: 9th March, 2022
OCLC Number/Unique Identifier: 9445952693
In pregnancy, the incidence of pulmonary embolism (PE) is increased fivefold when compared to nonpregnant women of the same age, and PE is one of the leading causes of death during pregnancy.However, the diagnosis of PE among pregnant women is complicated by concerns regarding radiation exposure. Systemic lupus erythematosus (SLE) is an autoimmune disorder with a wide array of presentations and a predilection to affect women of certain ethnic backgrounds. The hallmark of the disease is multisystem involvement, dispersed in time and severity. Usual pulmonary involvement includes pleuritis, pleural effusions, pneumonitis, shrinking lung syndrome, pulmonary hypertension, and alveolar hemorrhage. Pulmonary embolism (PE) is a relatively unusual presentation of SLE. We report the case of a 20-year-old primi at 21 weeks gestation with an acute PE with central chest pain and shortness of breath. The absence of overt signs and symptoms and traditional risk factors prompted a fragmentary workup. This led to the detection of antibodies sensitive for SLE, in the absence of overt signs and symptoms. We revive the concept of latent lupus, a condition construed as early lupus. We firmly suspect direct causation between SLE and PE. Further studies are needed to establish pathogenesis to facilitate early diagnosis and prevent morbidity and mortality from PE. Due to persistent hypotension, thrombolytic therapy with streptokinase was administered and the clinical and hemodynamic response was excellent, with no maternal or fetal hemorrhagic complications. The clinical presentation of pulmonary embolism is sometimes camouflaged by the physiological changes that occur in pregnancy and diagnosis is often delayed by a reluctance to expose the fetus to ionizing radiation.
Control of arterial hypertension and risk of new-onset of atrial fibrillation in patients with metabolic syndrome
Published on: 10th March, 2022
Background: An association between Atrial Fibrillation (AF) and Metabolic Syndrome (MS) a constellation of abnormalities (high blood pressure, hyperglycemia, dyslipidemia, and abdominal obesity), has been demonstrated. There have been many studies that have shown that elevated blood pressure (BP), was significantly associated with an increased risk of AF. It is uncertain whether maintaining the optimal BP levels can prevent AF in the patients with MS categorized as ‘high-risk’ patients.Objective: The aim of this study was to evaluate the influence of control of BP on the occurrence of new-onset atrial fibrillation in patients with Metabolic Syndrome.Methods: Into this observational study, was enrolled 435 consecutive patients (210 males and 225 females) aged 45-79 years who fulfilled criteria for MS. Participants were selected among primary and secondary care patients, who were receiving ongoing care for arterial hypertension in the period from November 2018 till November 2021. The study was conducted at outpatients in 5 Health Care Clinics (3 Secondary Health Care Clinics and 2 Primary Health Clinics). Patient were categorized according to their BP levels as Group 1-patients with controlled BP, {(patients aged < 65 years Systolic Blood Pressure (SBP) of 120 - 130 mmHg, patients aged ≥ 65 years SBP of 130 - 139 mmHg)} and Diastolic Blood Pressure (DBP), {(patients aged < 65 years of < 80 mmHg. but not < 70 mmHg; patients aged ≥ 65 years of 85 - 89 mmHg)}, or Group 2-patients with uncontrolled BP(> 130/80 mmHg),and in patients aged ≥ 65 years BP (≥ 140/90 mmHg ). Results: New-onset of AF, was more frequent in participants with uncontrolled BP, respectively (34.7% vs. 19.5%, p = 0.009).Patients with uncontrolled BP have more frequent persistent AF (15.2% vs. 0.04%) and permanent AF (0.08% vs. 0.02%), whereas there was not significant changes between groups in relation to frequency of paroxysmal AF, respectively (12.8% vs. 10.9%, p = 0.29). There was observed significant association of uncontrolled BP with: increased frequency of AF (OR = 2.193; 95% CI 1.390 - 3.439), persistent AF (OR = 3.931; 95% CI 1.771 - 8.084), permanent AF (OR = 4.138; 95% CI 1.383-12.381), LA. Dimension ≥ 2.2 cm/m2 (OR = 2.089, 95% CI 1.330 - 3.252), BMI (OR = 5.226, 95% CI 3.155 - 8.659) and 5-risk factors for MS, respectively (OR = 2.998, 95% CI 1.833 - 4.901).Conclusion: Optimal BP levels, can reduce the frequency of new-onset AF in patients with MS categorized as ‘high-risk’ patients. Uncontrolled BP was associated with an increased risk of both subtypes of AF (persistent and permanent) in the patients with MS categorized as ‘high-risk’ patients.
Fibromuscular dysplasia and aortic dissection
Published on: 30th March, 2022
Fibromuscular dysplasia is a rare, non-atherosclerotic, non-inflammatory vascular disease that typically affects women between the ages of 20 and 60 years.Although any artery can be affected fibromuscular dysplasia most commonly affects the renal and carotid arteries. Fibromuscular dysplasia of the renal arteries usually presents with hypertension, while carotid or vertebral artery disease causes transient ischemic attacks, strokes, or dissection. Aortic dissection is rare. We present the clinical case of a patient with fibromuscular dysplasia with type B aortic dissection.
Prevalence and pattern of congenital heart disease among children with Down syndrome seen in a Federal Medical Centre in the Niger Delta Region, Nigeria
Published on: 11th April, 2022
Background: Down syndrome (DS), or Trisomy 21, is the most common genetic disorder in the world and congenital heart disease (CHD) contributes significantly to morbidity and mortality in this population. Early diagnosis and prompt cardiac intervention improve their quality of life. This study was done to determine the prevalence and pattern of congenital heart disease among children with Down syndrome seen at the Paediatric Cardiology Unit of Federal Medical Centre (FMC), Bayelsa State.Method: A prospective study of children with Down syndrome referred for cardiac evaluation and echocardiography at the Paediatric Cardiology Unit of FMC, Bayelsa State over four years from 1st January 2016 to 30th December 2019. Data on socio-demographic information, echocardiographic diagnosis, and outcome were retrieved from the study proforma and analyzed.Results: A total of 24 children with Down syndrome were seen over the study period. Their age ranged from 0 to 16years. The majority, 20 (83.3%) of the children with Down syndrome were aged 5 years and below. There were 13 males and 11 females with a male to female ratio of 1.2:1. A total of 23 (95.8%) of the children with Down syndrome had CHD. The most common CHD was AVSD (including complete, partial, isolated, or in association with other defects) in 66.6% followed by TOF in 8.3%. Multiple CHDs were seen in 43.5% of the children. Only one child (4.2%) had a structurally normal heart on echocardiography. All the children with Down syndrome had pericardial effusion of varying severity while 33% had pulmonary artery hypertension (PAH). The fatality rate among the children seen with Down syndrome over the study period was 34.8% and only one child (4.2%) had open-heart surgery with the total repair of cardiac defect during the study period. Conclusion: Morbidity and mortality are high among children with Down syndrome due to the high prevalence of CHD. Early referral, diagnosis, and prompt intervention are encouraged.

Possible conditions causing high intracranial pressure and papilledema include intracerebral mass lesions, cerebral hemorrhage, head trauma, meningitis, hydroce-phalus, spinal cord lesions, impairment of cerebral sinus drainage, anomalies of the cranium, and idiopathic intracranial hypertension (IIH) [1].
Persistent symptomatic hyponatremia post-COVID 19: case report
Published on: 16th May, 2022
OCLC Number/Unique Identifier: 9524461908
Background: Hyponatremia associated with COVID-19 is considered an independent risk factor for a prolonged hospital stay, intensive care admission, and death, but its causes and treatment are not yet well known. Many workers attribute hyponatremia associated with COVID-19 to acute kidney injury and nephropathy associated with the disease. Others suggest that it is related to the syndrome of inappropriate antidiuretic hormone secretion, sepsis, or hypothalamic-pituitary dysfunction. We report a case of persistent acute hyponatremia in a COVID-19 patient with multifactorial etiology. Case presentation: A managed 77 years with known hypertension, type II DM, ischemic heart disease, chronic kidney disease (stage 3B and on treatment) presented with post-COVID-19 pneumonia, confusion, fever, generalized fatigability, dizziness, and lower limb edema. COVID-19 ad has been diagnosed two weeks earlier with a positive nasopharyngeal swab and was managed with dexamethasone, 10 mg oral for 10 days, azithromycin, 500 mg once orally, and levofloxacin, 500 mg once orally. At presentation, laboratory investigation showed hyponatremia (127.7 mg/dl). Conclusion: The etiology of hyponatremia associated with COVID-19 is different from that in other cases of hyponatremia and its management should be individualized according to patient history and clinical assessment, and effort is needed to determine the exact cause.
Novel extractive visible spectrophotometric method for determination of antihypertensive drug irbesartan with sulfonephthalein acid dyes in tablets
Published on: 22nd June, 2022
Irbesartan (IRB) is one of the drugs used for the treatment of hypertension. The present work develops and validates two methods for the evaluation of irbesartan in bulk and tablets. Sulfonephthalein acid dyes, bromophenol blue (BPB), and bromocresol purple (BCP) were used to produce stable yellow ion-association complexes with the basic drug IRB in dry chloroform. The colored products are quantified spectrophotometrically at their corresponding λmax. The relation between the absorbed signal and the drug concentration was linear up to 45.0 μg mL-1 (n = 6, r ≥ 0.9998). LOD reaches 40 ng mL-1. The composition of the ion associates was found 1:1 by Job’s and mole ratio methods. Application of the suggested methods to dosage forms is presented with percentage recoveries ranging from 99.33% to 101.67%. The results of the analysis were validated statistically and compared with the official method. No interference was observed from common pharmaceutical adjuvants.
Role of perioperative plasma D-dimer in intracerebral hemorrhage after brain tumor surgery: A prospective study
Published on: 2nd August, 2022
Background: Intracerebral hemorrhage (ICH) is one of the most feared complications after brain tumor surgery. Despite several factors being considered to influence bleeding, an increasing number of clinical studies emphasize that hemostatic disorders, developed during surgical aggression and tumor status, could explain unexpected ICH. The objective of this prospective study was to evaluate the influence of perioperative D-dimer levels on ICH after brain tumor surgery. Methods: This prospective, observational, 18-month study, at a single third-level hospital, included all consecutive adults operated on brain tumors and postoperative stay in an intensive care unit. Three blood samples evaluated D-dimer levels (A-baseline, B-postoperative and C-24 hours after surgery). The normal range considered was 0-500ng/ml. ICH, as a primary outcome, was defined as bleeding that generates radiological signs of intracranial hypertension either by volume or by mass effect on the routine CT scan 24 hours after surgery. Other tumor features and hemostasis variables were analyzed. Chi-squared and Fisher’s exact test were used in the inferential analysis for qualitative variables and Wilcoxon and T-Test for quantitative ones. P-value < 0.05 was considered significant for a confidence interval of 95%. Results: A total of 109 patients operated on brain tumor surgery were finally included, 69 male (63,30%) and 40 female (36,70%), with a mean age of 54,60 ± 14,75 years. ICH was confirmed in 39 patients (35,78%). Their average of DDimer was A-1.526,70 ng/dl, B-1.061,88 ng/dl, and C-1.330,91 ng/dl (A p0.039, B p0,223 C p0.042, W-Wilcoxon test). The male group was also associated with ICH (p0,030 X2 test). Of those 39 patients with ICH, 30 in sample A (76,9%), 20 in sample B (51,28%) and 35 in sample C (89,74%) had a D-dimer > 500 ng/dl (p0,092, p1, p0,761 X2 test) and the relative risk of developing a postoperative hematoma in this patients was increased 0,36-fold presurgery, 0,25-fold postsurgery and 0,40-fold 24hours after surgery. D-dimer variation, had no statistical significance (p0,118, p0,195, p0,756 T-test).

In 2017, I submitted a manuscript to the journal Archives of Biotechnology and Biomedicine belonging to Heighten Science Publications Corporation. Within one week I already received the response from the editor. All processing steps were really fast so in terms of a speedy publication I can particularly recommend the journal Archives of Biotechnology and Biomedicine. The responsible contact person of the journal was always available, which gives a trustworthy impression to the author. Also the peer review process was clear and constructive. So from my experience with Heighten Science Publications Corporation I can recommend publishing there.
