Extremely large hemangioma of the liver: Safety of the expectant management

Published on: 6th September, 2019

OCLC Number/Unique Identifier: 8257068015

Hemangiomas are known as congenital vascular malformations that can affect almost any organ or tissue, with the liver being the most common intra-abdominal organ to be involved. It is well known that hemangiomas are the most common benign tumours of the liver, and develop in about 4-20% of people, mainly young adult females. Recently, due to the dramatic rise in the use of imaging studies for different purposes, a parallel increase in the incidence of these tumours has been noticed. Most liver hemangiomas are small (less than 4cm in diameter), asymptomatic and found incidentally during abdominal operation for other indication or on radiologic studies. Giant liver hemangioma is defined as hemangioma with a diameter of more than 5cm. This unique and uncommon type of haemangioma usually poses therapeutic challenges for the treating physician, especially hepatic surgeons, due to the unclear natural history, and due to the risk of life threatening complications is yet to be established. While it is already proved by several studies that conservative management of giant hepatic hemangioma is safe, it is not known whether observation of the extremely large hepatic hemangioma (tumours larger than 10cm) is safe as well. The aim of this article is to review the English literature to find out if conservative management of the extremely giant liver hemangioma is safe and can be recommended.

Outcome of laparoscopic varicocelectomy with mass ligation technique for symptomatic varicocele

Published on: 6th September, 2019

OCLC Number/Unique Identifier: 8251963462

Background: Varicocele therapy is a controversial issue. No single approach is adopted as the best therapeutic option. Testes get blood supply from testicular artery, cremasteric artery and artery to the vas deference. So ligation of testicular artery in the abdomen do not cause ischemia to the testis. This was already demonstrated in many studies. Classical Palomo varicocelectomy also consists of open ligation of testicular vessels in the retroperitoneum. En mass ligation of testicular vein and artery is technically easy and fast in laparoscopic varicocelectomy (LV). Chance of missing some veins are also less. Henceforth recurrence is also less. Recurrence and post-operative complications are high when only testicular vein is ligated by laparoscopy in the retroperitoneum. We wanted to see the outcome of laparoscopic varicocelectomy by mass ligation technique. Methods: 56 patients of symptomatic varicoceles were included in the study from the outpatient services. Symptomatic varicoceles of grade 2 to grade 3 were operated from January 2012 till January 2019 over a period of 7(seven) years in Jahurul Islam Medical college Hospital. The patients were selected for dull pain and ugly veins not for infertility. All were operated by laparoscopy with en-mass ligation of testicular vein and artery in the retroperitoneum. They were followed up for a period of six months after surgery. We collected all the data in a retrospective manner. Results: The average operation time was 27±3 minutes. Average post-operative hospital stay was 32±7 hours. There were no technical failures requiring conversion to open varicocelectomy. There was no incidence of hydrocele formation nor testicular atrophy. One patient of bilateral varicocele had 50% reduction of his varicocele. We considered this a recurrence. All other patient had complete reduction of varicocele. One patient developed hemo-peritoneum due to dislodgement of hemo-clip, which required laparotomy. He did not require any further surgery for his varicocele. Conclusion: Laparoscopic varicocelectomy with mass ligation technique is safe, effective, less time consuming and easy to perform. Recurrence and post-operative complications are minimum. Plastic hemo-lock should be used rather than titanium heom-clip for ligation of testicular vessels. There is no incidence of testicular atrophy or any adverse effect on testis.

Similarity between Some Biological Systems, Organotropism and Metastatic Process: Active Role Played By Secondary Organ?

Published on: 19th June, 2018

OCLC Number/Unique Identifier: 7757049040

According to literature, about 90% of death from cancer is related to metastasis. Metastatic process present many similarity to some other biological processes. Once we have examined some relevant biomedical literature, by understanding the real causes of metastasis, it would become much more possible to introduce new therapeutic strategies to delay or in some cases even to stop this kind of killer process. Breast cancer, as an example, produces metastasis to different organs, which seems to be related to the subtype. We believe that a deep understanding of the roles of breast cancer cells and their interactions with the liver microenvironment in early breast cancer metastasis could be a crucial factor for the design and development of effective BCLM breast cancer liver metastases therapeutic strategies and to better understand the general process. Let’s suppose the secondary organ or organs can be considered as incubator/s for the primary metastatic cells. What kind of consequences we can have in therapy field if there is an active regulating role in determining the location of secondary cancers? Let’s observe the role played by liver, bone marrow, CNS central nervous system, lungs, lymphocytes and other secondary locations/organs a little bit closer or maybe from a different angle let’s suppose we try to come up with just a hypothesis. Just let’s take this as a possibility, and we take the thread to see where it takes us.

Changes in the frequency and intensity of Tinnitus using the Suppressive Noise Spectrum

Published on: 21st July, 2017

OCLC Number/Unique Identifier: 7325433767

Objective:To report findings of improvement in patient tinnitus intensity and changes in frequency using a novel suppressive noise spectrum. Design: Single-subject; each subject served as his or her own control. Each patient received treatment, and changes were measured over time. Setting: Tertiary referral via university otolaryngology and hospital audiology as well as audiology clinics in the region. Patients: Fifteen tinnitus ears in 8 patients. Interventions: Therapeutic and rehabilitative. Main Outcome Measures:: Tinnitus frequency, tinnitus intensity, and tinnitus questionnaire. Results (Findings): After 3 months of exposure to the customized suppressive noise spectrum therapy, patients showed a shift in tinnitus frequency in addition to a significant decrease in tinnitus intensity from the pre-treatment to post-treatment condition (p<0.05). Typically, improvement was gradual based on comparing 3 sets of data collected at baseline, 1.5 months and 3 months. Conclusion: Using suppression in tinnitus is novel. Based on our findings, using a customized suppressive noise spectrum is effective in shifting the frequency, reducing the intensity of subjective tonal tinnitus, and improving the handicap based on THQ test. From this seminal report, factors related to maximizing its effectiveness (e.g., length of listening time, level of hearing loss, and application for alternative tinnitus types) may be considered for future research.

OCLC Number/Unique Identifier: 9272357985

The outbreak of new coronavirus acute respiratory disease (SARS-CoV-2) has been a major global challenge for the scientific community to save humanity. While, the unviability of the vaccine keeps most classes of society, especially African countries, suffer from the healthcare problem. Conventional medicine plants become the alternative method for the therapeutic because it contains valuable bioactive compounds. This brief review devoted the importance of medicinal plants such as Citrus, olive, garlic, ginger, green tea, woad, broad-leaf privet, Japanese torreya, and saffron crocus, by their antiviral effects (anti-SARS coronavirus, anti-HSV, and anti-HIV diseases) and their promising uses as probable boosters of the immune and anti-inflammatory response from SARS-CoV-2 infection. Based on scientific reports, bioactive compounds could inhibit 3-chymotrypsin-like cysteine protease and human protein ACE2, where these facts can be attractive to develop effective drugs.

Nano-formulations for Ophthalmic Treatments

Published on: 29th December, 2017

OCLC Number/Unique Identifier: 7325061328

Ocular disorders encompass a multitude of diseases that are unique in their cause, therapy and degree of severity. Due to distinctive morphology of the eye, efficient ocular drug delivery has proven to be a difficult task. Current treatments of ophthalmological diseases include the usage of both intrusive as well as nonintrusive methods such as injections, eye drops, ointments, gels etc. The current state of the art drug delivery methods are associated with low bioavailability and therefore nanotechnology based drug delivery approached are evolving as for improving the therapeutic index of currently used drugs against variety of ocular disorders. This review highlights the recent developments in nano-formulations for ophthalmic treatment and also offers discussions towards the future prospectus of nano-formulations in the mainstream of ophthalmic diseases.

Bilateral transient osteoporosis of the hip with unilateral fracture in a 40 years old pregnant woman

Published on: 2nd April, 2021

OCLC Number/Unique Identifier: 8998601789

Purpose: Some physiological events in women’s life such as pregnancy and lactation can be associated to a condition known as Transient Osteoporosis of the Hip (TOH); if not promptly diagnosed it can lead to significant consequences such as femoral neck fracture. In this paper we describe a case of bilateral TOH, focusing on the importance of early treatment and how it influenced the outcome. Methods: A 40 years old post-delivery woman came to our attention for hip pain and a left femoral neck fracture was diagnosed. Magnetic resonance (MRI) showed bilateral edema of the femoral head. She underwent total hip replacement on the left side; toe-touch weight bearing and pharmacological therapy were prescribed for the right hip. Results: MRI at nine months showed complete regression of the femoral head and neck edema; the patient was clinically asymptomatic. Conclusion: If not promptly diagnosed and treated, TOH can potentially evolve in fracture. Many therapeutic strategies have been suggested since now; we believe that avoiding weight bearing on the involved hip as early as possible is the key to recovery.

Protective functions of AEURA in Cell Based Model of Stroke and Alzheimer disease

Published on: 6th June, 2017

OCLC Number/Unique Identifier: 7317651488

Stroke and neurodegenerative diseases including Alzheimer’s disease (AD) are responsible for a major proportion of mortalities in the elderly. We have previously investigated novel mechanism-based therapies of AEURA in cell culture models against viral infection and in glutamate excitotoxity. In our new studies, we propose that the homeopathic formula AEURA could serve as a potential therapeutic agent for stroke & for AD. In examining AEURA treatment of PC12 cells exposed to glutamate excitotoxicity, hypoxia /re-oxygenation injury and A-Beta toxicity. We demonstrated an increased survival rate in AEURA treated cells by comparison to control cells. In examining the therapeutic potential of AEURA in PC12 cells this homeopathic agent was found to be neuroprotective against either glutamate induced toxicity, hypoxia /re-oxygenation stress or cell stress resulting from viral infection (with either HSV-1 or rhinovirus). Our ongoing studies involve examining the neuroprotective potential AEURA in vivo using rodent models of stroke & AD.

Limb ischemia after coil migration used for a hypogastric aneurysm embolization

Published on: 10th February, 2021

OCLC Number/Unique Identifier: 8930779953

Hypogastric artery aneurysms are an uncommon entity. When the diameter achieves > 30-35 mm, they should be treated. Endovascular repair may be considered as first line therapy. One therapeutic option for internal iliac artery aneurysm exclusion is its embolization with or without covering the ostium with a covered stent. They may be some complications when it is not, as a distal coil migration that may produce ischemic symptoms. We are presenting a 73-years-old male admitted to hospital with an acute right lower limb ischemia caused by a coil migration. He recently underwent a right hypogastric artery aneurysm endovascular treatment by coil embolization without covering the hypogastric ostium with a covered stent. The patient underwent an emergency surgery to remove the coil by a transfemoral surgical approach with posterior thrombectomy of the secondary thrombus. Actually, he remains asymptomatic and with right posterior tibial pulse. Covered stent placement at the common iliac artery and external iliac artery could be the best option to avoid the risk of aneurysm rupture caused by endotension and the risk of distal coil migration.

Antiviral activity of Eucalyptus camaldulensis leaves ethanolic extract on herpes viruses infection

Published on: 13th October, 2017

OCLC Number/Unique Identifier: 7317651634

Eucalyptus camaldulensis (Ec) is considered as a traditional medicinal plant with valuable therapeutic effects. Here we evaluated the antiviral activity of its ethanolic leave extract on different herpes viruses. Vero cells were infected with either of the tested viruses [herpes simplex virus -1 and 2 (HSV-1, HSV-2) and Varicella-Zoster Virus (VZV)] with or without treatment with Ec extract and viral infection development was evaluated by plaque assay. Our results showed significant antiviral activity of the examined extract against all tested viruses. The 80%-MeOH fraction of this extract offered the highest activity against these viruses with 50% inhibitory concentration (IC50) of 0.1±0.08, 0.3±0.02 and 1±0.03 μg/ml against HSV-1, HSV-2 and VZV respectively and 50% cytotoxicity (CC50) at 700 μg/ml. The highest antiviral effect of this fraction was obtained mainly when it was added during and post infection (p.i.) or when it was added only p.i. Also, this fraction significantly reduced the amount of infective endogenous viral particles in cells that were treated with the 80%-MeOH fraction only post viral entry into the host cells. A synergistic antiviral effect against all tested viruses was also observed when cells were treated with a combination of acyclovir (ACV) and 80%-MeOH fraction of Ec. Further study is required for the isolation and identification of the anti-virally active component/s of this fraction.

Exploring pathophysiology of COVID-19 infection: Faux espoir and dormant therapeutic options

Published on: 5th May, 2020

OCLC Number/Unique Identifier: 8620512199

COVID-19 virus structural components: The 2019-nCoV, also called SARS-CoV-2, was first reported in Wuhan, China in December 2019. The disease was named Coronavirus Disease 2019 (COVID-19) and the virus responsible for it as the COVID-19 virus, respectively, by WHO. The 2019-nCoV has a round, elliptic or pleomorphic form with a diameter of 60–140 nm. It has single-stranded RNA genome containing 29891 nucleotides, a lipid shell, and spike, envelope, membrane and hemagglutinin-esterase (HE) proteins. Steps in progression of COVID-19 illness: Once inside the airways, the S protein on the viral surface recognizes and mediates the attachment to host ACE-2 receptors and gains access to endoplasmic reticulum. The HE protein facilitates the S protein-mediated cell entry and virus spread through the mucosa, helping the virus to attack the ACE2-bearing cells lining the airways and infecting upper as well as lower respiratory tracts. With the dying cells sloughing down and filling the airways, the virus is carried deeper into the lungs. In addition, the virus is able to infect ACE2-bearing cells in other organs, including the blood vessels, gut and kidneys. With the viral infestation, the activated immune system leads to inflammation, pyrexia and pulmonary edema. The hyperactivated immune response, called cytokine storm in extreme cases, can damage various organs apart from lungs and increases susceptibility to infectious bacteria especially in those suffering from chronic diseases. The current therapeutics for COVID-19: At present, there is no specific antiviral treatment available for the disease. The milder cases may need no treatment. In moderate to severe cases, the clinical management includes infection prevention and control measures, and symptomatic and supportive care, including supplementary oxygen therapy. In the critically ill patients, mechanical ventilation is required for respiratory failure and hemodynamic support is imperative for managing circulatory failure and septic shock. Conclusion: Confusion, despair and hopes: There is no vaccine for preexposure prophylaxis or postexposure management. There are no specific approved drugs for the treatment for the disease. A number of drugs approved for other conditions as well as several investigational drugs are being canned and studied in several clinical trials for their likely role in COVID-19 prophylaxis or treatment. The future seems afflicted with dormant therapeutic options as well as faux Espoir or false hopes. As obvious, not all clinical trials will be successful, but having so many efforts in progress, some may succeed and provide a positive solution. Right now, though, confusion and despair prevail.

COVID-19: The possible medical strategies

Published on: 9th June, 2020

OCLC Number/Unique Identifier: 8620504344

In late 2019, a pandemic crisis started in Wuhan, China, swept the whole world. The disease is caused by the SARS-CoV-19 virus that belongs to the corona family of viruses. The virus mainly caused failure of respiration, and led to many deaths worldwide. The main focus of research and medicine is to find more about the virus, as well as the development of effective preventive and therapeutic measures. While many trials and opinions have been published, which might support or contradict each other, this article tries to provide a simplified viewpoint about the disease. We highly recommend the therapeutic strategies to include drug combinations that can target the pathogenesis at many levels. For example, a combination of an effective anti-viral Remdesivir, soulable ACE2, and an immune modulator.

Serological and virological profile of patients with chronic hepatitis B infection in Eritrea

Published on: 24th July, 2020

OCLC Number/Unique Identifier: 8639906724

Background: Hepatitis B virus infection is a major cause of liver associated morbidity and mortality with diverse spectrum of disease. It is estimated about 15% to 40% of patients with hepatitis B virus infection progress to chronic hepatitis and about 15% to 25% die from disease complications. The main aim of this study was to evaluate the serological and virological markers of patients with chronic hepatitis B virus infection to determine the natural history of chronic hepatitis B infection in the Eritrean setting. Methods: A laboratory-based cross-sectional study was conducted on 305 patients with HBsAg positive who presented to Orotta National Referral Hospital, Halibet Hospital, Sembel Hospital and National Health Laboratory in Asmara, Eritrea from January 2017 to February 2019. Enzyme-linked immunosorbent assay was performed to detect hepatitis B serological markers (anti-HBc, HBsAg, anti-HBsAb, HBeAg and anti-HBeAg). Hepatitis B DNA viral loads and liver transaminase levels were determined. Data analysis was conducted using SPSS version 25.0. Results: A total of 305 patients presented with HBsAg positive serology with a mean age of 41.3 (± 13.7) years ranging from 16 to 78 years. Males were 218 (71.5%) and females 87 (28. 5%).Anti-HBc was positive in 300 (98.4%), of which 293 (97.5%) were positive for HBsAg and 7 (2.3%) positive for anti-HBs. Among these 293 patients, 20 (6.8%) were HBeAg positive/anti-HBe positive, 242 (82.6%) HBeAg-negative/anti-HBe-positive and 31 (10.6%) were HBeAg negative/anti-HBe-positive. Detectable HBV DNA was found in 122(41.6%) of the 293 cases. Alanine transaminase was normal in 90% of HBeAg-positive and in 91.2% of HBeAg-negative patients. Hepatitis B DNA viral load was >2,000 IU/mL in 67 (22.86%) and >200,000 IU/mL level was more frequently detected in HBeAg positive (20.0%) compared to HBeAg negative (1.8%) subjects (p < 0.001). Conclusion: This study shows predominance of HBeAg-negative and low replication phase of HBV infection among patients in Eritrea. It also documented that most patients had chronic infection with normal liver transaminase levels in the absence of biochemical signs of hepatitis. This study will provide a basis for therapeutic evaluation of patients and planning national treatment guidelines in the Eritrean setting.

OCLC Number/Unique Identifier: 8870088144

In the actual COVID-19 emergency, as pandemic disease, in many countries at the same time there was the rapid need to use preventive and therapeutic measures to control the diffusion of infection. In PC AREA (Italy north) in the period between March and May 2020, in fact, were observed about 1000 deaths related to COVID-19 (in march 2020 + 271% death vs 2019). Between all the measure submitted by public international institution like WHO, OMS, CDC and many other, the deeply use of disinfectants product became a crucial fact in safety procedure and protocols. The high amount of this disinfectants and antiseptic was needed especially in hospital settings or assimilates structure (named as COVID-19 hospital) but also for territorial healthcare need. So it was needed to buy from industries this product but also to start an internal production in galenic laboratories. This because pharmaceutical industries not provided in some cases the request amount of this “”safe life products. In this work is reported a practical experience in a public hospital, Pc AREA related GALENIC extra -ORDINARY PRODUCTION of disinfectants and antispetics. The result of this local experience experience can be easily translated to other countries in the world (advanced or also not advanced).

Exploring COVID-19: Relating the spike protein to infectivity, pathogenicity and Immunogenicity

Published on: 27th January, 2021

OCLC Number/Unique Identifier: 8906007931

Introduction: SARS-CoV-2 life cycle: The disease which reportedly began in Chinese city Wuhan in November-December 2019 manifesting as severe respiratory illness, soon spread to various parts of the world, and was named COVID-19, and declared a pandemic by WHO. The life cycle of SARS-CoV-2 begins with membrane fusion mediated by Spike (S) protein binding to the ACE2 receptors. Following viral entry and release of genome into the host cell cytoplasm there occurs replication and transcription to generate viral structural and non-structural proteins. Finally, VLPs are produced and the mature virions are released from the host cell. Immunogenicity of the spike protein: The S protein is considered the main antigenic component among structural proteins of SARS-CoV-2 and responsible for inducing the host immune response. The neutralising antibodies (nAbs) targeting the S protein are produced and may confer a protective immunity against the viral infection. Further, the role of the S protein in infectivity also makes it an important tool for diagnostic antigen-based testing and vaccine development. The S-specific antibodies, memory B and circulating TFH cells are consistently elicited following SARS-CoV-2 infection, and COVID-19 vaccine shots in clinical trials. The emerging SARS-CoV-2 variants: The early genomic variations in SARS-CoV-2 have gone almost unnoticed having lacked an impact on disease transmission or its clinical course. Some of the recently discovered mutations, however, have impact on transmissibility, infectivity, or immune response. One such mutation is the D614G variant, which has increased in prevalence to currently become the dominant variant world-over. Another, relatively new variant, named VUI-202012/01 or B.1.1.7 has acquired 17 genomic alterations and carries the risk of enhanced infectivity. Further, its potential impact on vaccine efficacy is a worrisome issue. Conclusion: THE UNMET CHALLENGES: COVID-19 as a disease and SARS-CoV-2 as its causative organism, continue to remain an enigma. While we continue to explore the agent factors, disease transmission dynamics, pathogenesis and clinical spectrum of the disease, and therapeutic modalities, the grievous nature of the disease has led to emergency authorizations for COVID-19 vaccines in various countries. Further, the virus may continue to persist and afflict for years to come, as future course of the disease is linked to certain unknown factors like effects of seasonality on virus transmission and unpredictable nature of immune response to the disease.

A Perspective on therapeutic potential of weeds

Published on: 18th June, 2020

OCLC Number/Unique Identifier: 8628652609

Nature gives us a diverse plethora of floral wealth. Weeds have been recognized as invasive plant by most of scholars in today’s world with extraordinary travel history. They are considered to be noxious for adjoining plant species and also as economic hazard. Weeds inhabited in almost entire biomes and have capability to survive in harsh conditions of environment thereby become source of inspiration for finding novel phytoconstituents. Weeds play a significant role in absorbing harmful micro pollutants that are affecting ecosystem adversely. There are so many examples like canna lily, bladder wort, coltsfoot, giant buttercup etc. playing crucial part in sustaining environment. Different isolation and characterization approaches like high pressure liquid chromatography, gas chromatography, ion exchange chromatography, nuclear magnetic resonance, mass spectroscopy etc. have also been fetched for obtaining novel constituents from weeds. The main aim of this review is to analyze the therapeutic potential of weeds established in New Zealand and effort to unfold the wide scope of its applications in biological sciences. Upon exploration of various authorized databases available it has been found that weeds not only are the reservoir of complex phytoconstituents exhibiting diverse array of pharmacological activities but also provide potential role in environment phytoremediation. Phytoconstituents reported in weeds have immense potential as a drug targets for different pathological conditions. This review focuses on the literature of therapeutic potential of weeds established in New Zealand and tried to unveil the hidden side of these unwanted plants called weeds.

Co-extract mixture from Strophanthus hispidus (roots) and Aframomum meleguta (seeds) show phytochemical synergy in its anti-inflammatory activity

Published on: 11th December, 2019

OCLC Number/Unique Identifier: 8500735034

Background: Combination of extracts from multiple plants are typically used in ethnomedicine to putatively offer more potent chemotherapeutic and chemopreventive effects than that of individual extracts from single plants. Aqueous extracts from two multipurpose plants Strophanthus hispidus (roots) and Aframomum meleguta (seeds) are topically co-administered in the nasal cavities for the ethnomedicinal management of chronic sinusitis. Aim: This study assessed the potential phytochemical synergy between constituent extracts of Strophanthus hispidus (roots) and Aframomum meleguta (seeds) in its anti-inflammation, anti-microbial and anti-oxidant effects. Methods and Materials: Broth dilution assay assessed anti-microbial activities. DPPH radical scavenging assay examined the scope of anti-oxidant activities and inhibition of carrageenan-induced 7-day old chick feet oedema revealed anti-inflammatory activities. Results: Anti-microbial activities of individual plant extracts in broth dilution assay showed comparable potency to that of the co-extract mixture. Similarly, individual extracts showed levels of DPPH radical scavenging activities in anti-oxidant assay that was comparable to those found for the co-extract mixture. In contrast to these two effects, inhibition of carrageenan-induced 7-day old chick feet oedema revealed an anti-inflammatory activity evoked by co-extract mixtures that was greater than the sum of the individual potencies of the two extracts. Conclusion: The potential phytochemical synergy of the two plants extracts in its anti-inflammatory response largely validates ethnomedicinal practice and generally confirms growing literature reports that ascribe the net pharmacological activities of herbal extracts to the combined multi-activities of unique phytochemical entities at multiple target sites.
