Association between bh4/bh2 ratio and Albuminuria in Hypertensive Type -2 Diabetic patients

Published on: 29th December, 2017

OCLC Number/Unique Identifier: 7338866036

Endothelial dysfunction and inflammation play a key role in the pathophysiology of diabetic nephropathy; Tetrahydrobiopterin (BH4) is an essential cofactor for nitric oxide synthase, when BH4 is reduced to dihydrobiopterin (BH2), endothelial dysfunction is induced. Purpose: The aim of this study is to evaluate the relationship between the levels of biopterins with albuminuria in type-2 diabetic hypertensive patients. Methods: We studied 30 hypertensive type-2 diabetic patients in whom biopterins levels were measured by reverse phase high performance liquid chromatography with fluorescence detection. Additionally, 24 h urinary albumin excretion was also measured (nephelometry). The levels of biopterins and albuminuria were correlated with the Pearson correlation coefficient. Results: We did not find a significantly correlation between biopterins levels and albuminuria, However, we found a significantly inverse correlation (R= -0.498, p<0.005) between the BH4/BH2 ratio and albuminuria. Conclusion: Our results suggest that the BH4/BH2 ratio instead of biopterins levels may be a marker of nephropathy in hypertensive type-2 diabetic patients.

Experiment of a novel four-spherical intrauterine contraceptive device with nickel-titanium

Published on: 20th October, 2020

OCLC Number/Unique Identifier: 8691260293

The aim of this study was to develop a novel four-spherical intrauterine contraceptive device (4-SIUD) with nickel-titanium (Ni-Ti) for human, and to evaluate the contraceptive effect. The 4-SIUD composed of 4 mesh spheres and 5 support arms. The shape of 4-SIUD was like a “T”. The height (H), upper width (D) and thickness of the 4-SIUD for macaques were 0.8 cm, 0.5 cm and 0.3 cm, and for human were 4.5 cm, 4.0 cm and 0.8 cm, respectively. The 4-SIUD was inserted into 5 macaques and pregnancy was not observed at 12 months. Three women used the 4-SIUD for 12 months, uterine perforations, expulsion, pain, and pelvic inflammatory did not occur. The results suggested that the 4-SIUD is appropriate for rhesus macaques and human use, and has a good contraceptive effect.

Posterior Reversible Leukoencephalopathy Syndrome in a patient after second dose of Rituximab for treatment of resistant Thrombotic Thrombocytopenic Purpura

Published on: 16th February, 2018

OCLC Number/Unique Identifier: 7347066275

Posterior reversible encephalopathy syndrome (PRES) is a neurological syndrome with clinical features of altered sensorium, headaches, visual problems and seizures. It has been associated with uncontrolled hypertension (HTN), thrombotic thrombocytopenic purpura (TTP) and immunosuppressive drugs. Rituximab has also been implicated as a cause of PRES that usually occurs after the first dose. We report a case of PRES that occurred after the second dose of Rituximab. A twenty three years old female known case of resistant TTP treated with multiple courses of steroids and plasmapharesis was admitted with renal failure, severe volume overload ad lower respiratory tract infection. She was treated with hemodialysis, intravenous antibiotics, steroids and plasma exchange (PEX).

4-year recurrence risk factors after tension-free vaginal tape-obturator as a treatment of stress urinary incontinence

Published on: 4th November, 2020

OCLC Number/Unique Identifier: 8875587752

Objectives: Tension-free vaginal tapes are the gold standard of the surgical treatment of stress urinary incontinence (SUI); however, long-term recurrence of SUI after this surgery has been a matter of problem. Here, we attempted to determine the incidence of its recurrence and to identify the risk factors of 4-year-recurrence of SUI after this surgery. Methods: Of all patients undergoing this surgery (n = 341, 2015-2019), 71 patients were met the study inclusion criteria. Of 71, SUI recurred in 8 patients, with the recurrence rate being 11.3%. The following three were identified to be independent risk factors: older age, history of delivery of macrosomic baby (>4 kg), and the presence of mixed urinary incontinence. The frequency of recurrence in cases with mixed incontinence amounted for 19.5%. Recurrence was 22 and 50% for women with macrosomic delivery once and more than twice, respectively. Conclusion: Advanced age, macrosomic delivery and mixed urinary incontinence have shown to be independent risk factors of recurrence of SUI after tension-free vaginal tape-obturator at 4 years. Key message: Stress urinary incontinence can recur so investigate possible risk factors is a priority. Our paper relates recurrence with: advanced age, fetal macrosomia and mixed incontinence.

Detection of IDH mutations in cerebrospinal fluid: A discussion of liquid biopsy in neuropathology

Published on: 17th September, 2020

OCLC Number/Unique Identifier: 8873201615

Isocitrate dehydrogenase (IDH) mutations are a common event in secondary glioblastoma multiforme and lower-grade adult infiltrative astrocytomas and independently confer a better prognosis [1,2]. These are highly conserved mutations during glioma progression and thus also a useful diagnostic marker amenable to modern molecular sequencing methods. These mutations can even be detected in sites distant from the primary tumour. We use an illustrative case of a patient with radiologically suspected recurrent astrocytoma and negative histology, but positive IDH-mutated tumour DNA detected within CSF. Our results demonstrated the usefulness of liquid biopsy for recurrent glioma within the context of equivocal or negative histopathological results, whilst also showing the ability to detect a de-novo IDH-2 mutation not present in the previous resection. Building on this ‘proof-of-concept’ result, we also take the opportunity to briefly review the current literature describing the various liquid biopsy substrates available to diagnose infiltrative gliomas, namely the study of circulating tumour DNA, circulating tumour cells, and extracellular vesicles. We outline the current challenges and prospects of liquid biopsies in these tumours and suggest that more studies are required to overcome these challenges and harness the potential benefits of liquid biopsies in guiding our management of gliomas

Estimating global case fatality rate of coronavirus disease 2019 (COVID-19) pandemic

Published on: 11th August, 2020

OCLC Number/Unique Identifier: 8646216717

Background: There is a huge global loss of lives due to COVID-19 pandemic, the primary epicentre of which is China, where the causative agent of the disease, SARS-CoV-2 was first emerged in December 2019. This study aims to explore the severity, in terms of case fatality rate (CFR), of COVID-19 pandemic. Methods: Data of ongoing COVID-19 global pandemic were retrieved from website of the WHO, and processed for the estimation of global (both including and excluding China) CFRs of COVID-19. CFRs were explored following the naive estimates, 14-day delay estimates, and linear regression model analysis, during January 25, 2020 to April 25, 2020, on weekly basis. To explore the current situation, in terms of CFR, data for the next 13 weeks (May 2, 2020 through July 25, 2020), were processed by naive and linear regression model analysis. Results: Mean CFRs, in naive estimates, were 4.59% for the world including China, and 3.62% for the world excluding China. The 14-day delay estimates of CFRs were 15.6% globally, and 21.65% in countries outside China. Following statistical model, global (both including and excluding China) CFRs were 6.81%, by naive estimates, and ~13%, by 14-day delay estimates. Global CFRs of COVID-19 during May 2, 2020 to July 25, 2020, ranged 4.1% – 7.04%, by naive estimates, and by statistical regression analysis the CFR was 3.19%. Conclusion and recommendations: The CFR might help estimate the need of up-to-date hospital supplies and other mitigation measures for COVID-19 ongoing pandemic, and therefore, instantaneous CFR estimations are recommended.

Atherogenic risk assessment of naive HIV-infected patients attending Infectious Diseases Service of Kinshasa University Teaching Hospital, Democratic Republic of the Congo (DRC)

Published on: 13th October, 2020

OCLC Number/Unique Identifier: 8689021635

Background and aim: Metabolic abnormalities are common in HIV/AIDS. Increasingly, lipid ratios are used as screening tools for dyslipidaemia in these medical conditions. The aim of this study was to assess the ability of 4 lipid ratios to predict cardiovascular risks. Methods: This is a cross-sectional and analytical study included 105 HIV+ patients followed in Kinshasa University Teaching Hospital (KUTH). Four indices [Atherogenic Index of Plasma (AIP), Castelli Risk Index (CRI) I and II, Atherogenic coefficient (AC)] were compared. Statistical analyzis consisted of measuring frequencies and means, Student’s t-tests, ANOVA and Ficher’s exact test, and the calculation of the Kappa value. Results: Lipid ratios predicted respectively the risk in 62% (AIP), 28.6% (CRI-I) and 23.8% (CRI-II). CRI-I and II were elevated, especially in women. The AIP appeared to be a better predictor than CRI-I and II to assess dyslipidaemia in general and the high-risk frequency. The cholesterol detected risk in 66.7% (Low HDL-C), 50% (High LDL-C), 38.9% (High TC and/or TG). The atherogenic risk was higher with age, advanced WHO stage, HIV-TB, HBV-HCV co-infections, smoking and alcohol intake. Haemoglobin (Hb) and CD4 counts were low when the risk was high. Age ≥ 50 years, stage 4 (WHO), CD4s+ ≤ 200 cells/µL were independent factors associated with atherogenic risk. Conclusion: Lipid ratios can be used as reliable tools for assessing cardiovascular risk of naïve HIV-infected patients who received HAART.

Clinical characteristics, management, maternal and neonatal outcome among seven severe and critically ill pregnant women with COVID-19 pneumonia

Published on: 30th November, 2020

OCLC Number/Unique Identifier: 8812298810

Pneumonia caused by the Novel coronavirus disease 2019 (COVID-19) is a highly infectious disease and the ongoing outbreak has been declared as a Pandemic by the World health organization. Pneumonia is a serious disease in pregnancy and requires prompt attention. Viral pneumonia has higher morbidity and mortality compared to bacterial pneumonia in pregnancy. All efforts are well exerted to understand the newly emerged disease features but still some areas are gray. The treatment is primarily supportive with antivirals, steroids, anticoagulation and antibiotics for secondary bacterial infection. Severe cases require intensive care monitoring with oxygen support, mechanical ventilation. Investigational therapies include convalescent plasma, cytokine release inhibitors and other immunomodulatory agents like interferons. The mortality appears driven by the presence of severe Adult Respiratory Syndrome (ARDS) and organs failure. COVID pandemic is a challenging and stressful socio-economic situation with widespread fear of infection, disease and death. In the specialty of obstetrics and gynecology, studies are being conducted to ascertain the manifestation of disease in pregnant women and the fetal outcome. The aim of our case series is to describe the demographics, clinical characteristics, laboratory and radiological findings, feto- maternal outcome of severe and critical COVID pneumonia in pregnant women in Latifa Hospital.

Equine Anti-Thymocyte Globulin (ATGAM) administration in patient with previous rabbit Anti-Thymocyte Globulin (Thymoglobulin) induced serum sickness: A case report

Published on: 23rd March, 2018

OCLC Number/Unique Identifier: 7666273824

Thymoglobulin is a rabbit-derived anti-thymocyte antibody directed at T-cells and commonly used for induction immunosuppression therapy in solid organ transplantation, especially in immunologically high risk kidney transplant recipients. Despite its frequent use and efficacy, the heterologous makeup of thymoglobulin can induce the immune system resulting in serum sickness which typically presents with rash, fever, fatigue, and poly-arthralgia in the weeks following drug exposure. ATGAM is another anti-thymocyte antibody, targeting the same epitopes, but differs from thymoglobulin by the animal in which the preparations are generated (equine vs. rabbit). Herein, we present a case of a patient with a known history of thymoglobulin-induced serum sickness, who presented with evidence of acute cellular and vascular rejection at their 12-month post-operative visit. Given their immunologically high risk status, they were successfully treated with ATGAM with improvement in their rejection and kidney function. To the author’s knowledge, this is the first case report of successful administration of ATGAM in a patient with a documented history of thymoglobulin induced serum sickness, demonstrating a possible treatment option for acute rejection in patients with reactions to thymoglobulin.

Emphysematous pyelonephritis – A case series from a single centre in Southern India

Published on: 3rd May, 2018

OCLC Number/Unique Identifier: 7666284358

TEmphysematous pyelonephritis (EPN) is a rare but potentially life-threatening necrotizing renal parenchymal infection characterised by the production of intra-parenchymal gas. The approach and the management of emphysematous has changed dramatically over the last two decades with the advent of computed tomography (CT)-based diagnosis and advances in antibiotic therapy as well as multidisciplinary intensive care of sepsis leading to an overall decline in mortality rates to 20-25%. The previously standard treatment for EPN which included nephrectomy of the affected kidney has been replaced by minimally invasive and nephron sparing surgery with better patient outcomes. We present our case series of 12 patients with EPN over a short period of two years treated at our tertiary care centre in South Western India.

Emergency medical care in palliative patients during the COVID-19 pandemic, it is important to provide a consistent treatment for stable patients that should be consistent with the goals and benefits, the perspective of these patients, but avoiding palliative patients with a poor prognosis that is unlikely to survive. Cancer is the second leading cause of death in the world around 8.8 million deaths a year. Worldwide, about 7-10 million patients are diagnosed with cancer each year, recently there has been a significant increase in the number of cases diagnosed with cancer. About 70% of cancer deaths are in low- and middle-income countries. The goals of emergency medical care based on the criteria of BLS and ACLS, that is should be done “Do not do resuscitation, do not intubate but continue medical treatment excluding endotracheal intubation without prospects for the patient, but offering BLS only treatment concentrated symptomatic. ED is often the only place that can provide the necessary medical interventions (e.g., intravenous fluids or pain management medications. Medications as well as immediate access to advanced diagnostic tests when needed such as CT, RM and other diagnostic and treatment procedures.

Experience with trans radial uterine artery embolisation for uterine fibroids in a tertiary center in Saudi Arabia

Published on: 1st December, 2020

OCLC Number/Unique Identifier: 8812313094

Trans-radial uterine artery embolization (UAE) is acknowledged as a non- invasive, cost-effective and safe procedure for the treatment of symptomatic fibroids. However, it is associated with the recurrence of symptoms like abnormal uterine bleeding and pressure symptom in some patients. This is a comparative study of our data with other international data, in the context of percentage reduction in fibroid size, accompanying controlling factors, short and long term follow up data analysis of the first two years was done. Careful pre-procedural counseling of future possibility of fibroid recurrence and means of management should be stressed. Materials and methods: A retrospective cohort study at the Security Forces Hospital in Riyadh, Saudi Arabia, was conducted. The study was done from 1st November 2017-31st October 2019, on symptomatic patients diagnosed with fibroids, who refused surgical treatment. The outcomes included: fibroid site, size and anatomical position, patients’ symptoms, general condition, and early and delayed complications. These data were compared with those from other international studies. Results: The study involved 23 patients (mean age: 39 years). The average percentage reduction in fibroid volume was 49%. There were no major complications and no recurrence of symptoms during the covered period. Data analysis revealed a poor correlation between the overall percentage reduction of fibroid size with fibroid number, age of patients’, and body mass indices. Conclusion: Despite poor correlation, we provided preliminary data of the first two years out of the total five-year projected period of the study where it showed effectiveness and relative safety of radial - UAE for fibroid.

AngioJetTM rheolytic thrombectomy induced intravascular haemolysis leading to Acute Kidney Injury requiring Dialysis

Published on: 3rd August, 2018

OCLC Number/Unique Identifier: 7815114583

Background: AngioJetTM rheolytic thrombectomy has been used in the treatment of deep vein thrombosis (DVT) to prevent post-thrombotic syndrome. Though not widely appreciated, it has the potential to cause intravascular haemolysis. Report: A 37 year old man with no previous medical history presented to his GP with a three week history of progressive right upper limb swelling. Doppler imaging confirmed right upper limb DVT and CT scan demonstrated thoracic outlet syndrome. The patient underwent AngioJetTM thrombectomy followed by IV heparin infusion. Successful revascularisation of the occluded vein was achieved. Overnight he developed haematuria, which was initially attributed to IV heparin. Urinalysis however revealed no red cells or casts. Apart from an Hb drop from 134 to 117 his blood profile and blood film showed no abnormality. He subsequently developed progressive oliguria with marked oedema and acute kidney injury (AKI). His creatinine peaked at 1070umol/l at 96 hours post procedure and he was started on intermittent dialysis. He remained dialysis dependent for 6 days. Ultrasound imaging excluded urinary obstruction. Autoimmune and vasculitic serology were negative. Intravascular haemolysis and haemoglobinuria was confirmed by raised LDH (1714u/L) and low haptoglobin (<0.1units). Direct Coomb’s test, Cold agglutinin test and paroxysmal nocturnal haemoglobinuria screen were negative. The patient’s renal function normalised over 3 months. Conclusions: The likely cause of this man’s AKI is heme pigment nephropathy from intra-vascular haemolysis. Increased awareness of this condition may allow early identification and intervention to reduce the risk of renal injury from AngioJetTM associated haemolysis.

Three year outcomes following positive cross match renal transplantation despite failure to convert to Negative Flow Cross Match after Desensitization

Published on: 30th August, 2018

OCLC Number/Unique Identifier: 7856143044

Desensitization allows successful transplantation of patients with a positive crossmatch (PXM) against their live donor. We evaluated outcomes following PXM renal transplant despite failure to convert to negative flow cytometric crossmatch (FCXM) after desensitization. Patients that underwent desensitization before PXM transplant between 1/1/00 and 11/1/11 were identified for analysis. Patients who received a transplant despite failure to convert to negative FCXM were identified as the not converted group. Patients who converted to negative FCXM after desensitization comprised the converted group control arm. 108 patients were desensitized before PXM transplant, (not converted group=42; converted group=66). Mean eGFR was comparable between groups at all time points, and 3-year eGFR was 57.8 mL/min vs. 57.1 mL/min, p=0.91. Patients with eGFR < 30mL/min at 3 years did not differ significantly (28% vs. 14%, p=0.15). Biopsy-proven rejection rates were numerically higher within the not converted group for each type of rejection and time point, but the values did not differ significantly. Opportunistic infections rates were comparable. Patient survival (95% vs. 91%) and death-censored allograft survival (84% vs. 95%, p=0.07) were similar between arms at 3 years post-transplant.

Each individual has a unique way of learning which is based on personal background [1]. Neuro Linguistic Programming is an ideology of communicating with an individual. It can be applied in social relations like teaching fields [2]. Each medical student deals with a set of new information in his unique way. For example with regard to the following text on vacuum extraction, one learner focuses on definition, while the other focuses on spelling, and the third one just on shapes [3] (Figures 1-3).

An audit on outpatient hysteroscopy – cervical dilatation, failure rates and patient satisfaction

Published on: 12th January, 2021

OCLC Number/Unique Identifier: 8885999148

Aims: To audit the use of cervical dilators, local anaesthetic, and failure rates in outpatient hysteroscopy over a two-year period in University Hospital Kerry. To review the experiences of women attending the outpatient hysteroscopy clinic (OHC) over a two-year period in University Hospital Kerry. Methods: Retrospective data review was carried out. Green-top Guideline No. 59: Best Practice in Outpatient Hysteroscopy, published by the Royal College of Obstetricians and Gynaecologists (RCOG), was the standard used for comparison. Results: Two hundred and twenty women were seen over a two-year period. The average age was forty-eight. The most common complaint being of menorrhagia/irregular bleeding per vaginum (PV). Local anaesthetic was used in just under one third of cases of which half required cervical dilatation. Most women reported experiencing mild to moderate levels of discomfort however most would opt for an outpatient hysteroscopic procedure again if required. Discussion/Conclusion: Outpatient hysteroscopy is a well-tolerated and safe procedure. Suitability for outpatient hysteroscopy is not predictable based on parity of menopausal status. Women would elect to undergo outpatient hysteroscopy again if required and this is likely due to several reasons including convenience and lack of requirement for general anaesthetic.

Explicating the presentations of Acanthamoeba keratitis with special concern in the COVID-19 pandemic ambient

Published on: 18th March, 2021

OCLC Number/Unique Identifier: 8987259294

This article presents an overview of information regarding Acanthamoeba keratitis per epidemiology, host-pathogen interactions, clinical manifestations, risk factors, environmental implications, diagnosis, treatment and management as well as COVID-19 characteristics which may be taken into cognizance for suspected infected patients, researchers and ophthalmologic practitioners. Acanthamoeba spp. is pathogenetically ubiquitous in nature. Acanthamoeba keratitis is considerably an ocular-threatening and debilitating keratitis that exhibits contumacious characteristics which hinder or impede treatment or management. At inception, Acanthamoeba generally depicts atypical clinical features which are frequently misdiagnosed as other microbial keratitis. Fundamentally, it constitutes a rare corneal infection of which the aetiologic agent is the protozoon Acanthamoeba spp. in contact lens wearers, presenting features of severe ophthalmic distress, blurred vision, blepharospasm, ocular excoriation, extraneous entity sensation and photophobia culminating in aberrant visual functionality. These are perspicuously due to retarded prompt and adequate treatment and management. Personal and environmental hygiene, especially on the hands, face and ocular areas as advised for the COVID-19 protocol could prevent contamination and dissemination of Acanthamoeba keratitis infection. The differentiating relatedness of Acanthamoeba keratitis, COVID-19 ophthalmologic infections and other ocular problems may not have been clearly elucidated.

Aim of this work is to analyze the coronavirus viral surface properties related the pattern of electrical features. This chemical physical property is relevant and crucial to set profile of diffusion, severity of disease, efficacy of therapeutic strategy and in order to search new way to fight COVID-19 and the NEW VARIANT. The phenomena of immune evasion and the different pattern of efficacy towards variants of some vaccine or some antibodies combination produce the need to verify if considering the electrical feature of viral surface can be a right tool or not. As result of this research it is possible to submit to the scientist that the viral surface properties and electrical feature can be an element to be considered in various preventive or treatment measure. The specificity of action of some vaccine or antibodies seem to tell us that also the aspecific methods are useful. A specific chemico physical factors can influence the electrical charges viral surface behavior. Hpertonic saline solution, humidity, electrical charge barrier in mask are simply example of the effect. That can be obtained action on viral surface chemico -physical properties.
