Background: This article reviews current knowledge of Gaucher’s disease (GD) and liver involvement and reports our experience: how many patients with chronic liver disease of unknown origin could be affected by Gaucher’s disease. Patients and methods: Over 24 months, we tested 75 sine causa chronic liver disease patients (30 women and 45 men, mean age 55 years, range 15 to 77). Results: None of the 75 patients was affected by Gaucher’s disease. Conclusion: We believe that the chronic liver disease patient is unlikely to be affected by Gaucher’s disease. Probably this disease is to be found in cases of coexistence of hepatic disease and other symptoms of Gaucher’s disease (bone, neurological, bone marrow involvement).

There is growing evidence that gastroesophageal disease is influenced by the esophageal microbiome, and that commensal bacteria of the oropharynx, stomach, and colon are thought to have a role in modulatiing pathogenesis. These emerging hypotheses are based on observed changes in the composition of the esophageal flora, notably, repeated observations: 1. There is an abundance of gram-positive bBacteria in the healthy esophagus. are more gram positive prevalent 2. The esophageal bacterial population becomes increasingly gram negative with disease progression. Associated with this shift to a more gram negative prevalence is an increase in the potential for the presence of antigenic lipopolysaccharide (LPS). The immunoreactivity of LPS endotoxin thought to promote susceptibility to inflammation and disease. The pathogenesis of the more common diseases of the esophagus e.g. gastroesophageal reflux disease (GERD), esophageal dysmotility (achalasia), eosinophilic esophagitis (EoE), Barrett’s esophagus (BE), and esophageal cancer, are well-established. Emerging data suggest however, that these are all characterized by an immune-mediated inflammatory cascade, propogated by a dysbiotic state. Thereby, the ability of the healthy “normative state” to protect against foreign bacteria is compromised. This dysbiosis thereby can create adverse inflammatory or immunoregulatory responses with progression of disease. In the normal healthy state, the esophageal microbiome is constituted in-part, by a multitude of gram positive bacteria, many of which produce antibacterial peptides called bacteriocins. Bacteriocins are selective and used to maintain population integrity by killing off foreign bacteria. When the “normative biome” is interrupted (e.g. antibiotics, medications, diet, environmental factors), the constitutional changes may allow a more hospitable imbalance favoring the proliferation of opportunistic pathogens. Therefore it seems rational that defining, perhaps that defining, perhaps cultivating, a protective bacterial community that could help prevent or mitigate inflammatory diseases of the esophagus. Furthermore, in conjunction with evidence demonstrating that some bacteriocins are cytotoxic or antiproliferative toward cancer cell lines, further exploration might provide a rich source of effective peptide-based drug targets. Therapeutic options targeting the microbiome, including prebiotics, probiotics, antibiotics and bacteriocins, have been studied, albeit the attributable effects on the esophagus for the most part, have been unrecognized by clinicians. This review focuses on the current knowledge of the involvement of the microbiome in esophageal diseases (most notably GERD/Barrett’s esophagus/esophageal cancer) and identifies emerging new concepts for treatment.

Background:While recognition and documentation of true drug allergy is critically important, most physicians acknowledge that its prevalence is likely overestimated, often on the basis of historical, sometimes anecdotal evidence. Correct or not, once applied, drug allergy labels may result in altered, potentially inferior therapy, increased costs and prolonged hospitalisation. Objective:Estimate the point prevalence, accuracy and symptomatology of self-reported drug allergy in a typical, large NHS Acute Trust adult inpatient population. In the subset with penicillin allergy (PA), estimate additional management costs from the use of alternative antibiotics and readmission rates in the previous 5 years. Methods:Data on self-reported drug allergies were extracted from 440 adult inpatient prescription charts over a 4 month period. Where penicillin allergy (PA) was reported, alternative antibiotic regimens were recorded and their additional costs calculated. Hospital electronic records were used to assess readmission rates of PA patients. Results:194/440 inpatients (44.5%) reported at least one drug allergy. Antibiotic allergy was most commonly reported (51%), followed by analgesic (23%) and antiemetic (12%) allergy. PA accounted for 76% of reported antibiotic allergy. The commonest reported symptoms were cutaneous (42%) and gastrointestinal (18%). Where antibiotic therapy was required for patients with PA to manage acute infections, Ciprofloxacin, Clarithromycin, Teicoplanin, Clindamycin and Cefuroxime were the most commonly employed alternatives. Extrapolation of these figures to include the entire Trust inpatient population suggested that the use of alternative antibiotics in PA patients incurred additional annual expenditure of £268,000. Further, 87% of PA patients had been admitted more than once in the preceding 5 years, with 74% requiring further courses of antibiotics during these admissions. Conclusion:Self-reported drug allergy, and in particular PA, is common in hospital inpatient populations and, in addition to the potentially unnecessary hazards to individual patients resulting from the use of alternative antibiotics, results in a considerable additional financial burden to the healthcare system. This problem could be eliminated by the provision of a nationwide and equitable tertiary Allergy service.

Background: Intensive care patients are often in need of sedation to endure being intubated. Light sedation is increasingly common since it has been proved to offer benefits such as faster recovery to patients. Aim: The aim of this study was to describe critical care nurses’ experiences of nursing patients lightly sedated with dexmedetomidine. Research Methodology: Qualitative personal interviews were conducted during 2015 with 10 critical care nurses in Sweden. Interview transcripts were analysed using inductive qualitative thematic analysis. Results: Light sedation of the patient facilitated communication and interaction with him or her, and the relationship between the patient and his or her family members. Dexmedetomidine was described as a fairly new drug, and the critical care nurses stated that they needed more knowledge about it and about sedation scales in order to learn more about the drug’s mechanism of action and its potential side effects on patients. Conclusion: It is important to critical care nurses to learn more about dexmedetomidine and about sedation scales to assess levels of sedation, as light sedation has been shown to benefit the patient as opposed to deep sedation that can increase recovery time.

Objectives: The study aims to assess the knowledge, attitude and practices of physicians who deal with pediatric age group SSTIs in reference to the Infectious Diseases Society of America (IDSA) guidelines on this regard that was published in 2014. Background: Skin and soft tissue infections rank among the most frequent infections worldwide. It is estimated that over 11 million ambulatory healthcare visits occur each year in US for skin and soft tissue infections due to Staphylococcus aureus (S. aureus) alone. SSTIs are clinical entities of variable presentation, etiology and severity that involve microbial invasion of the layers of the skin and underlying soft tissues. SSTIs range from mild infections, such as pyoderma, to serious life-threatening infections, such as necrotizing fasciitis. One of the main challenges in managing SSTIs is to be able to identify those who need immediate inpatient intervention versus the more stable ones that can be manages in outpatient basis. In June of 2014, The Infectious Diseases Society of America (IDSA) released evidence based guidelines that has nicely covered all aspects related to the management of SSTIs. Method:An anonymous 20-item survey exploring knowledge, attitude and practices associated with diagnosis and management of skin and soft tissue infection was distributed to physicians of different levels of expertise (from residents to consultants) in the departments of Pediatrics, Emergency Medicine and Family Medicine in different governmental facilities in Al-Ain city which is one of the major cities in United Arab Emirates.

Background: Chronic rhinosinusitis (CRS) is a heterogeneous and multifactorial inflammatory disease of the nasal and paranasal mucosa. To date, no internationally standardized uniform classification has been developed for this disease. Usually, a phenotype classification according to CRS with (CRSwNP) and without (CRSsNP) polyposis is performed. However, through a variety of studies, it has been shown that even within these phenotypes, different endotypes of CRS exist, each with a different underlying inflammatory pathophysiology. In this mini-review, we aim to outline the essential immunological processes in CRSwNP and to highlight the modern therapeutic options with biologics derived from this disease. Methods: Current knowledge on the immunological and molecular processes of CRS, especially CRSwNP, was compiled by means of a structured literature review. Medline, PubMed, national/international trial and guideline registries as well as the Cochrane Library were all searched. Results: Based on the current literature, the different immunological processes involved in CRS and nasal polyps were elaborated. Current studies on the therapy of eosinophilic diseases such as asthma and polyposis are presented and their results discussed. Conclusion: Understanding the immunological basis of CRSwNP may help to develop new personalized therapeutic approaches using biologics. Currently, 2 biologics (dupilumab, omalizumab) have been approved for the therapy of CRSwNP (polyposis nasi) in Europe.

The problem of the alcohol misuse in Russia is well known; but there is a tendency to exaggerate it, which seems to be used to disguise shortages of the healthcare and public assistance. In this way, responsibility for the relatively low life expectancy is shifted onto the patients, who are supposed to drink excessively. In parallel, there is a tendency to exaggerate successes of the anti-alcohol campaign (1985-1989) and to trivialize the harm caused by the campaign e.g. mass consumption of surrogates [1]. The bias can be illustrated with the example of papers by Yuri Razvodovsky [2-5]. Yuri asked me per e-mail to write a “friendly” letter to the Editor referring to his article. An excerpt from the correspondence is presented here as documentary evidence (Figure 1). In reply, I cited the phrase: “The official statistical data do not support the claims that the… аnti-alcohol campaign contributed to the dramatic growth in fatal poisonings by non-beverage alcohol surrogates” [4] and commented that I witnessed mass poisonings with window cleaner in 1988. Considering the large scale of the window cleaner sales, it was knowingly tolerated by authorities. Poisonings with methanol and organochlorides (used e.g. in dry cleaning) were known to occur as well. Yuri replied that “there are two realities: one, which we both witnessed, and another-official statistics” (Figure 1). Obviously, Razvodovsky should have discussed in his articles the “realities we both witnessed”, i.e. common knowledge and observations, otherwise his papers are misleading. 

Background: There is a huge gap in the U.S. health care system when it comes to the prevention of substance abuse and addiction, specifically involving adolescents. It has been determined through literature review that parents in Utah are not informed about/knowledgeable of/aware of the current usage of alcohol/drugs in the adolescent population in this area or the inherent risks involved with consumption/use/misuse/abuse/addiction. Aim: The overarching aim of the doctoral project was to prevent Utah County middle school students from harmful alcohol and drug consumption by involving parents in prevention efforts. The prevention goals of this project included: increased parental knowledge of the brain disease of addiction, warning signs of adolescent drug use, what to do if their child is already using, and increased parental self-efficacy on communicating with teens on this subject. Design: For parents to be productively involved, barriers were broken down through education. The DNP student completed a 15-minute presentation at five separate parent meetings that took place annually during middle school registration at Lehi Jr High. Population: The education was for parents, foster parents, guardians, etc. of first-year middle school students only; an estimated 420 participants were in attendance. Data collection and analysis: A pre-and post- combined self-efficacy and knowledge test was given to the attendees. Data was gathered from 117 appropriately completed tests and analyzed using a paired t-test. The results were studied to evaluate effectiveness of the program relating to parental self-efficacy and knowledge. Findings: The presentation ultimately increased parental self-efficacy and knowledge (p-value <0.01) which in turn increases protective factors and decreases risk factors associated with adolescent substance abuse. Conclusions: The DNP project was successful, and the results assisted in the refinement of the presentation for sharing on a mass level to all Jr. High schools in Utah County, Utah.

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.

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.

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.

Inferior vena cava (IVC) involvement by intraluminal extension of tumor is infrequent, occuring in 4% to 10% of patients with renal cell carcinoma (RCC) [1-5]. Based on the cephalic extension of the thrombus, Mayo [6] described a classification of inferior vena cava thrombi in 4 categories, which has implications on surgical complexity, estimated blood loss (EBL) and peri-operative complications, but not cancer-specific survival [2,7]. Level III IVC thrombus is classified as being located in the retro-hepatic IVC below the diaphragm. Total resection of this tumor is the best chance of cure when no distant metastases are present [4,8]. Actually, open radical nephrectomy with concomitant thrombectomy is still the standard treatment. This procedure is technically challenging and involves a large incision and prolonged convalescence [9]. Recently, the feasibility of robotic IVC thrombectomy has been demonstrated, with potential lower EBL and shorter hospitalization and convalescence [7,10-14]. This surgery requires thorough knowledge of surgical anatomy, detailed pre-operative preparation and meticulous robotic technique [7]. The key point in the surgical management is the correct assessment of the extension of the endocaval thrombus, what is mainly based on radiological examinations [8]. Although Ultrasonography (US) and computerized tomography (CT) are useful in demonstrating the extent of the thrombus, CT is not always accurate in delineating the superior margin of the tumor in the IVC. More precisely, magnetic resonance imaging (MRI) can demonstrate a tumor thrombus and its extension, besides signs of wall invasion, being extremely useful to surgical procedure planning [8,15]. Vena cavography is not additive to US, CT, and MRI, and it increases the risk of contrast-associated renal injury [4,8]. However, new modern image technologies has emerged to help surgical planning, as three-dimensional visualization technique (3DVT) based on routine CT or MRI processed image data [16-20]. Recently, a comparative study showed advantage of 3DVT in management of complex renal tumor during laparoscopic partial nephrectomy [20]. This modality is able to demonstrate anatomy relations, allowing the surgeon to observe the relationship between targeted tumor and peripheral structure before surgery and perform virtual manipulation. This kind of preoperative accurate assessment can enhance surgeons confidence of surgical procedure and decrease surgical risk and incidence of complications [20]. There is no report in the literature of the use of this type of technology in cases of IVC tumor thrombus. We present the use of 3D holographic interactive reconstruction in a single case of robotic radical nephrectomy with level III IVC thrombectomy.

Five key sectors of transport have been selected as the target groups: seafarers, truck drivers, dockworkers, rail workers and airline workers. Transport workers often operate under stressful working conditions, long-work hours, lack of good sleep, healthy diet and physical exercises that contribute to fatigue, impaired well-being, mental ill-health, stress and chronic diseases. The hypothesis is that good mental health workplace culture depends on good education, staffing and management. Objectives: To create, implement and evaluate a research based mental health culture promotion program Determinate existing researches and training programs, To study the knowledge, skills and needs for specific training in diferent age-groups Create and implement effective and relevant training, Produce training materials and scientific evidence available for ship owners, students and workers and to develop proposals for new mental health policies, legislations and regulations Methods: Multidisciplinary training and research methodology with quantitative and qualitative research methods will be used. Validated mental health culture promotion methods with new programs for the specific sectors. Expected impact • Significant less sickness absence and suicides • Benefit for the workers’ health including benefit for the company economy. • Policies developed for improved mental health culture based on the research. • The training programs are ready to be continued at the end of the project.

One of every four visits to eye care professionals is for dry eye disease which affects an estimated 7-34% of Americans [1]. Knowledge regarding etiology and treatments has advanced exponentially in the last 20 years. 

Irvine-Gass syndrome, is one of the most common causes of painless decrease in vision following even uneventful cataract surgery. It usually responds well to medical therapy, but, there are no widely acceptedconsensus on the efficacy of various therapeutic options for the treatment of Irvine-Gass syndrome. The patient presenting in this case report, has systemic hypertension and chronic obstructive pulmonary disease and he use oral anti-hypertension medication and inhaler steroid. He diagnosed as Irvine-Gass syndrome due to presence of decrease in visual acuity and macular edema with hyporeflective cystic intraretinal spaces in optical coherence tomography (OCT) since4th weekcontrol visitfollowing uneventful cataract surgery. After the responsiveness of several medications including topical steroid and non-steroidal anti-inflammatory drugs and intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF), intravitreal sustained-release dexamethasone implant was applied. The visual acuity improved to 0.00 logMAR at 1st month after intravitreal dexamethasone therapy and consecutive OCT images showed complete resolution of macular edema with a normalization of the foveal profile.The visual acuity and foveal architecture remained stable in 2-year follow-up period and additional treatment was not needed. To the best of our knowledge, this is the first reportthatmentions the increment of visual acuity after a single dexamethasone implant, even though it did not response anti-VEGF combined with topical steroid and non-steroidal anti-inflammatory drugs. 

The work is an attempt to create a complete system of conditions which influence genesis, existence, and response characteristics of stapedial reflex in impedance audiometry. The author divides the conditions into the internal-reflex arc integrity, temporal acoustic summation, mixed-external auditory meatus and middle ear, and internal-side of stimulation and energy content of the stimulus. The system of conditions that influence stapedial reflex is based on a criterion, that stapedial reflex depends on energy, which is percepted by the inner ear as subjective loudness. The system of conditions stated in this work is based mainly on the author’s own experiments and measurements, which are herein also documented. At the same time, these results are in accordance with data in literature as quoted. This system is not closed-it potentially may be completed using the basic criterion and further knowledge.

WHO declared the coronavirus disease 2019 (COVID-19) outbreak, caused by SARS-CoV-2, to be a pandemic on March 12, 2020. In Morocco, the first case was reported in March 2nd 2020. The mental health of general population, medical and nursing staff especially has been greatly challenged. The aim of the present article is to explore the stress status of medical and nursing staff associated with exposure to the COVID-19. The medical staff was asked to complete a self-reported questionnaire anonymously. In University Hospital Mohamed VI, in Marrakesh, Morocco. During May 2020. In total, 120 valid questionnaires were collected. Among them, there were 57 residents (47,5%), 30 internes (25%), 22 nurses (19%) and others: medicine students and technical staff. The age was between 23 and 60 years. 15% of professional lived alone, 85% with their family, 74% lived with an old person or with a person having a chronic disease. In our study: the severity of symptoms in 36% of the asked professional, deaths among health professionals in 15%, death of a family member in 14%, the rapid spread of pandemic in 90%, the lack of knowledge in 83%, and finally contamination risk especially if comorbidity associated in 2%. Further risk factors: feelings of being inadequately supported by the hospital in 42%, fear of taking home infection to family members or others in 80%, being isolated, feelings of uncertainty and social stigmatization in 43%. The psychological presentation was the nightmare 19 in %, the insomnia in 48%, the somatization in 18%, the irritability in 22%, the aggressiveness in 14%, the nervousness in 70% and the drowsiness in 5%. During the vulnerability of the individual’s conditions during and after the COVID-19, psychological intervention should be done and a mental health support for the health professional.

Background: An infectious disease caused by a novel coronavirus called COVID-19 has raged across the world since December 2019. The novel coronavirus first appeared in Wuhan, China, and quickly spread to Asia and now many countries around the world are affected by the epidemic. The deaths of many patients, including medical staff, caused social panic, media attention, and high attention from governments and world organizations. Today, with the joint efforts of the government, the doctors and all walks of life, the epidemic in Hubei Province has been brought under control, preventing its spread from affecting the lives of the people. Because of its rapid spread and serious consequences, this sudden novel coronary pneumonia epidemic has become an important social hot spot event. Through the analysis of the novel coronary pneumonia epidemic situation, we can also have a better understanding of sudden infectious diseases in the future, so that we can take more effective response measures, establish a truly predictable and provide reliable and sufficient information for prevention and control model. Methods: We establish different models according to the different developments of the epidemic situation, different time points, and different response measures taken by the government. To be specific, during the period of 2020.1.23-2020.2.7, the traditional SIR model is adopted; during the period of 2020.2.8-2020.3.30, according to the scientific research results, it was considered that the novel coronary pneumonia has a latent period, so in the later phase of epidemic development, the government has effectively isolated patients, thus we adopt the SEIQR model accordingly. During the period of 2020.3.31-2020.5.16, because more asymptomatic infected people were found, we use the SEIQLR model to fit. Finally, through a SEIR simulator, considering the susceptible number, the latent number, the infected number, the cured number, death number and other factors, we simulate the change of various numbers of people from the beginning to the next 180 days of novel coronary pneumonia. Findings: The results based on the analysis of differential equations and kinetic models show that through the prediction of the model established in the first phase, the epidemic situation of novel coronary pneumonia in Hubei Province was controlled at the end of March, which is in line with the actual situation. The rest of Hubei province, except for Wuhan, lifted control of the departure channel from 0:00 am on March 25, and Wuhan was also unblocked on April 8. Through the establishment of the second-phase model, it is found that the epidemic situation will reach its peak in mid-February. For example, the quarantine admission of the hospital declined after mid-February, which is inseparable from the measures to build square cabin hospitals in early February so that more and more patients can be admitted. The model established in the third phase shows that the epidemic had been completely controlled by the end of May, which is also in line with the reality. Because in mid-May, the Wuhan government conducted a nucleic acid test on all the citizens to screen for asymptomatic infected persons to fundamentally control the spread of novel coronary pneumonia. Interpretation: Hubei Province, as the center of the initial outbreak of novel coronary pneumonia, people were forced to be isolated at home during the Spring Festival, the most important Chinese holiday, and the whole society was in a state of suspension of work and study. The Chinese government had taken many measures in response to the epidemic, such as shutting down the city, vigorously building square cabin hospitals, and prohibiting people from gathering. At the beginning of May this year, the epidemic in Hubei Province was finally effectively controlled. For ordinary citizens, we should not cause unnecessary panic about the unknown novel coronavirus. Instead, we should fully understand and be familiar with this virus. In addition to the relevant medical knowledge, we should also understand the spread of infectious diseases through appropriate mathematical models. By mathematical models, we can understand the degree of harm of infectious diseases, when to control it, how to stop it, and use scientific views to reveal the original face of the novel coronavirus to the public without causing social panic.

Behavioral dentistry is an interdisciplinary science, which needs to be learned, practiced and reinforced in the context of clinical care and within the community oral health care system. The objective of this science is to develop in a dental practitioner an understanding of the interpersonal, intrapersonal, social forces that influence the patients’ behavior. The clinician must acquire knowledge to develop appropriate behavioral skills with an improved quality of communication and management of patients. Behavior dentistry also teaches to develop a recognition and understanding that the body and mind are not separate entities and focuses on patients’ social, emotional and physiological dental experiences. Behavior is an observable act. It is defined as any change observed in the functioning of an organism. Learning as related to behavior is a process in which experience or practice results in relatively permanent changes in an individual’s behavior. Self-perceptions of dental-facial appearance begin with aesthetic values shared within families and based generally on social norms, but that they may be strongly influenced by peer values and specific experiences of individual children, particularly those involving social responses. Theories incorporating concepts of social comparison and self-efficacy suggest that individuals evaluate themselves in comparison with others in their social environment. Children who perceive themselves to be attractive will reflect those perceptions in their behaviors and generally will receive confirming social responses. The comparison group may express an attractiveness norm that reflects negatively on the individual’s behavior. This, in turn, can affect the individual perceived sense of self-efficacy or adequacy within that group and lead to behaviors that reflect more negative beliefs about the self, thereby inviting still more negative social responses. Patient cooperation is the single most important factor every dentist must contend with. Major considerations are • Regularity in keeping appointments • Compliance in wearing removable appliances • Refraining from chewing hard and tenacious substances that are likely to distort or damage the teeth or crowns • Maintenance of oral hygiene. Laxity in following these instructions may lead not only to compromised treatment but also to slow progress of treatment, loss of chair time and frustration. What may be more interesting to the Dentist than the shaping of self-perceptions in the shaping of behavior that will ensure a successful result of treatment, that is, the patient’s adherence to prescribed routines for self-care and other regimens during Dental treatment. It is helpful in this regard to know that most patients expect improved dental-facial appearance as an outcome of treatment, but there is much more to know about factors influencing cooperation. Poor motivation can also contribute to non-compliance. The regulatory loop requires a motivational system to adjust behavior to coincide with the recommended regimen. A patient may recognize that the regimen is not being followed and yet simply not be motivated to correct the discrepancy. Poor motivation can also result from a lack of concern over the long-term health consequences of one’s behavior and/or a lack of belief in the treatment. Cognitive approaches that emphasize the personal relevance of the regimen or address misconceptions about the treatment may enhance motivation. Several approaches may be useful in treating poor compliance. Providing incentives or rewards for compliant behavior might be a useful strategy to enhance motivation. The cause of noncompliance is multifactorial and strategies to improve compliance must be tailored to fit each situation. Current Dental research focuses on a critical aspect of the feedback; specifically, the input received by the comparator that quantifies the actual amount of adherent behavior. Likewise, Patients, parents, and clinicians need a way to ascertain this information.

This non-systematic review outlines the current knowledge concerning provenance, chemical composition and properties of apple cider vinegar, its general health effects, as well as the currently available knowledge concerning its action on fat storage, physiological mechanisms of its effects, as well as its safety and recommended dosage for treatment of obesity.
