The emergence of COVID-19 worldwide in an unprecedented pandemic. COVID-19 has a significant mortality, mostly from acute lung injury. We reviewed the available literature from China and Europe in regard to the behavior of SARS-Cov2 and ability to adhere to the cell wall [1,2]. The evidence based literature describes three component for the virus to grant entry to the target cells including Cathepsin B/L (the viral cap protein needed for initial connectivity to the cell wall), the angiotensin converting enzyme 2 and a low PH environment to allow the first connectivity of the virus to the cell wall [3]. The goal of our Case study was to prevent SARS- SARS-Cov2 from entering target cells by raising the airways PH using sodium bicarbonate inhalation. The sodium Bicarbonate inhalation (4.2% concentration) has been used safely in Cystic fibrosis (CF) patients with inspissated mucoid impaction [3,4] and in chloride inhalation toxicity by opposing the effect of the low PH induced by the insulting agent [4,5]. It has not been administered for COVID -19 patients particularly prior to this study. 

We present a 54-year-old male with abdominal pain, Vomiting and weight loss since 5 months. Perforation was noted at recto-sigmoid junction and underwent Hartman’s procedure with end colostomy. Histology of sigmoid colon confirmed a Stercoral perforation without any evidence of dysplasia or malignancy. Patient had chemotherapy for squamous cell carcinoma (SCC) of epiglottis a year ago and was on codeine phosphate and Oromorph as and when required since his treatment for SCC for pain. Patient also had been suffering from constipation since he finished chemotherapy. Stercoral perforation always need to kept in mind in patients who present with constipation and need to take all patients who present with chronic constipation and initiate measures we encounter commonly in everyday practice. We present a brief review about Stercoral perforation and its management.

Levosimendan is a calcium sensitizer and its inotropic effect is mainly attributed to the troponin C of the myocardial fine filaments with calcium. Levosimendan also inhibits phosphodiesterase III. In contrast to inotropic effects, this does not increase calcium entry into the cell, which explains that levosimendan does not worsen myocardial diastolic dysfunction and may even improve diastolic function. Levosimendan does not increase the use of myocardial oxygen and increases coronary vasodilation and myocardial oxygen delivery. Levosimendan opens potassium channels and causes hyperpolarization in smooth muscle cell membrane, thus causing vasodilatation [1]. Levosimendan has also been reported to have antiinflammatory [2,3] and antiapoptotic effects [2].

Background: Despite its negative effects, approximately 23% of Palestinians (≥ 18 years) smoke cigarettes. Studies have shown physicians to be an important channel for smoking cessation intervention. This investigation examines physicians’ smoking-related knowledge, attitudes, and behaviors in the Gaza strip (Palestinian Territories). Methods and findings: A convenience sample of 154 physicians in medical and surgical units took part in this investigation (87.7% response rate). The data show that 37.8% of physicians in Gaza smoke, and most of them about 72% smoke in the hospital’s public spaces, thereby implicitly giving public approval for smoking. While 82.4% reported that they advise patients who smoke to stop, the majority (59%) also believe that their own smoking habits negatively influence the impact of that advice. Unfortunately, our survey showed that physicians’ knowledge levels towards smoking addiction and management were lower than expected (e.g. only 34% knew that nicotine dependence is a psychiatric disorder that necessitates treatment). The physicians in this study believed that the primary barriers to failure of their patients’ smoking cessation were the perceived lack of will (81.3%), and the strength of patients’ addiction (67.9%). Moreover, (61%) of physicians did not spend enough time to convince their patients to quit smoking. Conclusion: Smoking is common among Gaza-strip physicians, and unfortunately, most of them smoke in the hospital’s public spaces. Many obstacles face the smoking cessation program that some physicians linked it to patients, and others linked it to the health-care system. Furthermore, smokers in Gaza receive poor care regarding assessment, referral, and management of their smoking habit.

In this article different numerical techniques for solving optimal control problems is introduced, the aim of this paper is to achieve the best accuracy for the Optimal Control Problem (OCP) which has the objective of minimizing the size of tumor cells by the end of the treatment. An important aspect is considered, which is, the optimal concentrations of drugs that not affect the patient’s health significantly. To study the behavior of tumor growth, a mathematical model is used to simulate the dynamic behavior of tumors since it is difficult to prototype dynamic behavior of the tumor. A tumor-immune model with four components, namely, tumor cells, active cytotoxic T-cells (CTLs), helper T-cells, and a chemotherapeutic drug is used. Two general categories of optimal control methods which are indirect methods and direct ones based on nonlinear programming solvers and interior point algorithms are compared. Within the direct optimal control techniques, we review three different solutions techniques namely (i) multiple shooting methods, (ii) trapezoidal direct collocation method, (iii) Hermit- Simpson’s collocation method and within the indirect methods we review the Pontryagin’s Maximum principle with both collocation method and the backward forward sweep method. Results show that the direct methods achieved better control than indirect methods.

In this paper we summarise, in chronological order, all COVID-19 preventive measures undertaken by the Macau Special Administrative Region (SAR) government during the first quarter of 2020. The information and narrative contained herein may be of useful to other parts of the world in COVID-19 control and prevention, especially cities with ultra-high population densities. The four main lessons from Macau SAR are: (1) Proactive leadership and early prevention. (2) Strict adherence to community endemic control. (3) Clear prioritising of public health. (4) Planed relief for financial hardships amidst the post-pandemic recession.

Objective: The liver is the second most common site of distant metastases from breast cancer. We investigated the risk factor liver metastasis in patients with breast cancer. Methods: We studied Age, Menopausal status, Histologic Type, Tumor size, Number of cancerous axillary lymph nodes, in two groups with liver metastases with logistic regression to identify independent liver metastasis risk factors in breast cancer patients. Results: Age, menopausal status, number of cancerous axillary lymph nodes and tumor size are the independent risk factors liver metastases in patients with breast cancer. Conclusion: The increase number of cancerous axillary lymph nodes and tumor size may be diagnostic markers for liver metastases from breast cancer.

The onset of the pandemic has caused widespread concern about the rapid spread of the infection and serious concern about the lack of specific treatment for it. Calls and demands for strict compliance with sanitary and anti-epidemic measures, a sharp reduction in direct contacts and movements of people with the introduction of quarantine measures in large regions and even countries have become a familiar modern reality. All these efforts do not yet allow us to see and feel their positive results, and the next wave of infection destroys hopes for the likelihood of achieving rapid and complete success in the fight against this evil. At the same time, a detailed analysis of the material accumulated during this period allows us to identify the most problematic links in the process of diagnostics and providing care to such patients and to note the reasons that require priority solutions.

Owing to the ever westernizing lifestyles in developing countries like India, the escalation of oral cancer patients are in need of urgent plan of action. With tobacco being the commonest cause for causation of oral cancer, Global Adult Tobacco Survey, 2016-17 revealed that almost 28% of whole population of India is consuming tobacco in either smoking or smokeless form. With these increasing numbers, the expected death toll to be expected to touch 1-2 million mark by the year 2035 [1]. Although, the current Onco-medicine fraternity excels in rendering care to oral cancer patients in the form of surgeries, chemotherapy and radiation-therapy. Often, these treatment modalities impart some unwanted adverse effects like, docetaxel (DCT) is known for its hepatotoxicity [2,3] whereas, one of the commonly used cisplatin (CIS) presents with nephrotoxicity, neurotoxicity, bone marrow suppression and vomiting [4,5]. Literature suggests of many non conventional medicaments being tested in past for their anti onco-genic effect, where few being effective and others being questionable ones. Chlorhexidine being one among them showing some how promising anti onco-genic activity with feeble amount of studies being conducted in past. Chlorhexidine, one of the most commonly prescribed mouthrinse in the field of dentistry, with varying concentrations of 0.12% and 0.2% concentrations. Although, apart from being broad spectrum antibiotic, its capability to dismantle the protein – protein bond between anti – apoptotic Bcl-2 family protein Bcl-xL and its pro – apoptotic binding partners [6]. The current study was conducted on three cell lines of squamous cell carcinoma (SCC-4, SCC-9, SCC -15) and two pharynx carcinoma cell lines (FaDu and Detroit 562). The compounds induced apoptosis through mitochondria dependent apoptotic pathway in oral tumour cell lines. Another study conducted to assess the similar anti – oncogenic activites of chlorhexidine mouthrinse along with cranberry [7]. It was evident from results that, with increasing concentrations of chlorhexidine mouthrinse, there was increase in mean percent growth inhibition. The authors concluded saying, chlorhexidine has showed both anti cancerous as well as anti bacterial activity required to tackle common oral infections, part of common anti cancer therapy. Fernando Martínez-Pérez et al (2019) conducted study, where antitumor activity of Lipophilic Bismuth Nanoparticles (BisBAL NPs) and chlorhexidine on human squamous cell carcinoma was assessed using energy dispersive X – ray spectroscopy in conjunction with scanning electron microscopy (EDS-SEM). Study revealed, BisBAL NPs and chlorhexidine both showed cell growth inhibition on both cancer cell line (CAL-27) and human gingival fibroblasts (HGFs). Although, chlorhexidine showed non specific cytotoxicity for both tumoral and non tumoral control cells. The suggestive mechanism of action might be loss of cell membrane integrity [8]. Although Eliot MN (2013) conducted study, to assess the risk of head and neck squamous cell carcinoma secondary to use of alcohol containing and non alcoholic mouthwashes including chlorhexidine. The study was concluded with an assumption based on chlorhexidine mouthwash alters the oral flora [9], thus resulting in increasing risk exponentially through diverse change in oral bacteria and altered immune response with contribution towards genesis or promotion of cancer [10]. On the contrary, alcohol consumption and smoking are predisposing factors towards upper digestive tract cancer. The main causative factor being the first metabolite of alcohol, acetaldehyde. And much higher levels are derived from oral bacteria and thus, same can be altered in favour through usage of chlorhexidine mouthwash, to avoid excessive production of acetaldehyde intra orally. In conclusion, chlorhexidine mouthwash has been into dental practice since long and the role it plays in either ways has to be assessed by a multi dimensional study with cell lines including that of control to derive better compared conclusions.

Introduction: The contents of the retropharyngeal space are limited to fat and retropharyngeal nodes. Primary tumors originating from the retropharyngeal space are rare, therefore, the existence of schwannoma in the retropharyngeal space is infrequent. Method: This paper describes a case of a large schwannoma of the retropharyngeal space excised transorally with the use of co2 laser. This lesion measured about 6/6 x 3/5. Result: No peri-or post-operative complications were encountered. The procedure allowed quick resumption of an oral diet and a return to normal activity for the patient. Conclusion: This is, to our knowledge, the first report of this technique used in the excision of a large retropharyngeal space schwannoma.

Objective: Colorectal cancer is one of the most commonly occurring cancers in men and women worldwide as well as one of the most common causes of death from cancer. It has a higher prevalence in men than women. The treatment of colorectal cancer (surgically or through chemotherapy) severely affects both patients and their families. The objective of the study was to identify cases of colorectal cancer, evaluate their demographic and clinical data, and identify any statistical relationship. Methods: This is a retrospective study. The data were collected through the revision of cancer patients’ files in the Chemotherapy Center at Vlore Regional Hospital, Vlore, Albania. The analysis included files from 2015-March 2019. A total of 72 patients’ files with colorectal cancer were analyzed. Result: Mean age of patients 66.36 ± SD10.99 years old, range 38-86. Most of the patients were male (n = 45) and with colon cancer type (n = 44). 19 patients had treatment with surgery, radiation, and chemotherapy. 56.34% of patients with colorectal cancer are still alive. The results of the study are the same as the global trend in terms of age, gender, type of cancer but not in terms of years of survival, which appear lower. Conclusion: The study suggests that in demographic terms patients with colorectal cancer have no difference from world trend. There was also a marked lack of documentation regarding the clinical data of patients. The complete and accurate documentation of cases with colorectal cancer is recommended to develop quality models of nursing care as well as to design effective promotional and preventive campaigns for colorectal cancer.

The present study aimed to investigate and identify the association between the intake of allium vegetables and colorectal cancer (CRC) in population. A hospital‐based matched case‐control study was conducted between June 2009 and November 2011 in three hospitals. Eight hundred thirty three consecutively recruited cases of CRC were frequency matched to 833 controls by age (within 2.5 years of difference), sex, and residence area (rural/urban). Demographic and dietary information were collected via face‐to‐face interviews using a validated food frequency questionnaire. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated by using unconditional logistic regression.

Sexual addiction is a growing reality. The acknowledgment of this disorder requires to identify vulnerability factors. Besides, it would improve the management and treatment of these people. We used a cross-sectional study with a sample of voluntary subjects recruited online anonymously. A prepared questionnaire explored the general and clinical data of the sample. The psychometric scales used were: Carnes Sexual Addiction Screening Test, the French Big Five Inventory for personality dimensions and the Rosenberg Scale for self-esteem. Five hundred and ten individuals were included. 38 people (8%) had sexual addiction. 68 people (13%) had attenuated symptoms of sexual addiction. The average age of the group with sexual addiction was 30.8 years with a male predominance. The majority had a higher academic level, was single (39.5%) and are working (73.7%). Our study revealed that self-esteem was below average in 73.7% of people with sexual addiction. Concerning personality dimensions, individuals with sexual addiction had higher scores in Neuroticism. The analytic study showed that four variables were statistically correlated with sexual addiction: male sex; low self-esteem; a large N dimension and a low C and E dimension. The concept of sexual addiction, still poorly defined, is beginning to be recognized. The need for more research is required to identify the factors of vulnerability with the aim of developing the preventive axis and improving the quality of life.

For the millions of patients experiencing chronic pain despite pharmacotherapy, deep brain stimulation (DBS) provides a beacon of hope. Over the past decade the field has shifted away from DBS towards other forms of neuromodulation, particularly spinal cord stimulation (SCS). DBS for pain is still performed, albeit off-label in US and UK, and experiences variable success rates. SCS is an extremely useful tool for the modulation of pain but is limited in its application to specific pain aetiologies. We advocate use of DBS for pain, for patients for whom pharmacology has failed and for whom spinal cord stimulation is inadequate. DBS for chronic pain is at risk of premature neglect. Here we outline how this has come to pass, and in the process argue for the untapped potential for this procedure.

According to the World Health Organization definition, palliative care is an approach aimed at increasing the quality of life of patients and their relatives by addressing physical, psychosocial and spiritual needs and treating conditions early, such as pain while they are coming to terms with a life-threatening disease [1]. Palliative care services have started a rapid progress in developed countries such as Scandinavian countries, England and Canada since the beginning of 1990 [2]. Although palliative care cares for any patient who is in need of care, whether bed-bound or unable to look after themselves, one of the main area of interest is of course oncological patients and their relatives. Patients with advanced cancer, frequent sufferings from physical and psychological symptoms - primarily pain, reduced functional capacity, and reduced quality of life are in the scope of palliative care protocol [3]. The most common end-of-life symptoms and signs in palliative cancer patients are pain, anorexia, nausea, cachexia, weakness, dyspnea, ascites, anxiety, agitation, delirium, confusion and pressure sores. In order to achieve quality and continuous care in case management, a family doctor, specific branch specialist, nurse, dietician, psychologist, cleric, etc. should work together in a multidisciplinary approach and clinical guidelines and care protocols should be implemented [4]. However, it should be kept in mind that increasing the medication dose may not always be beneficial to the oncological patients in palliative services. The goal should always be maximum benefit with minimal tests and treatment. Palliative care does not aim to accelerate or postpone death; but it has many benefits in cancer patients and their relatives including the integration of the psychosocial and spiritual aspects of patient care into physical care, providing support for patients to live as active as possible until the last moment, improving the quality of life and the disease process, providing help and support in the grieving process [1,5]. Providing good care to advanced cancer patients requires that caregivers are educated and supported about their patients’ physical, psychological and social care needs. Balancing the physical and emotional needs of the caregivers will reduce the stress they experience, as well as increase the quality of life of their patients [6,7]. Professionalism in palliative care comes into play right at this point. There is no consensus in the medical world about by whom, when and to whom palliative care should be given. In this regard, the conflicts of opinion between specific branches such as anesthesia, internal medicine and neurology are inevitable. We think that the team leader should be a family physician or a palliative care specialist. The reason for this is the family medicine’s principles of core competencies including biopsycosocial, holistic, comprehensive approach and equal distance to specific branches. Of course when the palliative care specialist is the team leader the patient’s own family doctor still provides invaluable service because of his intimate and long-term knowledge about the patients. One key difference in some countries is that no distinction is being made between palliative and hospice care. Neither the insurance companies nor the state demands such classification because it doesn’t serve any practical purpose at the moment. However, in due time such distinction will be inevitable as one of the cost-cutting measure. Medical oncology will have to report about the expected survival of the cancer patients and it will further increase their workload given the exponential increase in cancer cases.

Background: the level of alcohol consumption per capita is an important indicator of the alcohol-related problems. However, it is difficult to estimate the real level of alcohol consumption, since part of the consumption comes from illegal sources. Aim: an overview of studies estimating the overall level of alcohol consumption in Russia. Methods: in this review, 9 articles were analyzed estimating the overall level of alcohol consumption in Russia. Results: in the period from 1956 to 2015 the overall level of alcohol consumption was subject to significant fluctuations: it grew almost linearly in the period from 1965 to 1979; decreased markedly in 1981; declined sharply between 1984 and 1987; rose sharply between 1991 and 1994; decreased significantly between 1995 and 1998; then increased significantly in the period from 1999 to 2003, after which it began to decline. The lowest estimate of the level of alcohol consumption for the entire period under consideration was obtained using the method proposed by Razvodovsky (7.25 litres - 1987), and the highest - using the method proposed by Norstrom (19.64 litres - 1994). Conclusion: despite a significant decrease in the level of alcohol consumption in Russia over the past decade, this level remains high.

Rectourethral fistula (RUF) is a divesting complication after prostate cancer treatment. The RUF incidence after radical prostatectomy is about 0.5% to 2%, [1,2]. Radiotherapy, criotherapy and high intensity focused ultrasound are other more severe causes [3,4]. Repair of RUF is a challenging surgical procedure. There are some possible approaches but transperineal is the most utilized. In cases of complex fistulas interposition of muscle flaps between the rectum and urethra is highly recommended. Gracilis muscle transposition (GMT) is the preferred, due to excellent mobility and vascularization for perineal reconstruction [5,6]. Dissection of the gracilis muscle is done using one, 2 or 3 large incisions in the medial border of the thigh. The aim of this report is present a new minimally invasive access to obtain a pediculate flap of gracilis muscle to interposition between bladder and rectum to treat RUF.

The hunger experiment was carried out in 1944 by Anselm Keys and others in the American city of Minnesota. The aim was to investigate the consequences of starvation in order to be able to restore the health of hunger victims of the Second World War. How could they be treated in the best possible way to regain a healthy weight? For this purpose 36 physical and psychosocial healthy young men were selected from a large group of men who refused to serve in the American Army. They were examined very carefully in the period before the hunger experiment which lasted 6 months. In this period they received only two mails a day with half of the number of calories they were used to eat. This period of malinutrition was followed by 3 months of refeeding. Not only their weight recovered quite well, but also the psychosocial consequences of starvation disappeared completely [1]. 

Methods: Experimental phase: Performed a partial nephrectomy off clamp in pig model followed by cauterization of lidocaine gel 2% with different power (control, 30W, 50W and 100W) in the kidney resection bed to evaluate efficacy and deep injury extension. Clinical phase: 20 patients submitted to laparoscopic or partial nephrectomy for low risk RENAL score were utilized greased lidocaine gel 2% with 50W in cautery scalpel to hemostasis of renal parenchima to validate efficacy and safety. Results: Experimental study shows that this technique is effective and promote better hemostasis with 50W and 100W, with deep injury of less than 3 mm. Clinical study confirm efficacy, good control of hemorrage, few complications and no transfusion. Minimal changes in hematocrit, haemoglobin and creatinine were observed. Conclusion: In this preliminary experience the use of this new alternative to hemostasis for low risk partial nephrectomy was satisfactory and with good intra and postoperative results. The best advantages were safety in terms of the depth thermal injury, low cost and absence of artifacts over the resection area observed at CT scan postoperatively.

Background: Epidemiological studies in smokers indicate a dose-response relationship between the number of cigarettes smoked per day and the risk of developing certain smoking related diseases. The alkaloid nicotine is the major pharmacologically active substance in tobacco. Objective: To estimate the cotinine level excretion in urine among smoked and smokeless tobacco users and nonsmokers among the Indian population. Materials and methods: The study sample consisted of 250 subjects who were apparently healthy, asymptomatic and not using any drug. The study sample was divided into smoked tobacco users (bidi and cigarette), smokeless tobacco users, both smoked and smokeless tobacco users and controls (non-users of tobacco in the past or present). Results: The mean Cotinine level in urine was significantly (p – value < 0.05) more among smoked tobacco users in comparison to smokeless tobacco users and non-users of tobacco. Whereas, the mean Cotinine level in urine was significantly (p – value < 0.05) more among smokeless tobacco users in comparison to non-users of tobacco.
