Abstract

Introduction: Basal cell carcinoma is the most common malignancy in humans. A number of treatment modalities are available. We performed this study in order to determine the efficacy of Mohs micrographic surgery in treatment of basal cell carcinoma.
Materials and Methods: This retrospective descriptive study was performed on 194 basal cell carcinoma (in 175 patients) were treated in Isfahan Al-Zahra Hospital from september 1999 to March 2003 with Mohs micrographic surgery. Data were obtained from patient's files and were analized by SPSS software.
Results: Of the 175 patients (with 194 basal cell carcinomas), 110 (62.85%) paticnls were male and 65 patients (37.14%) were females. The mean age of patients was 58±12.38 years. The majority of tumors were located on face and scalp. 180 of tumors were primary and 14 were recurrences. 17% of tumors were larger than 2cm. Recurrences of the tumor occured in 3 patients. The cosmetic results were excellent and good in 81%. The incidence of recurrnce rate was 0.9%.
Conclusion: Kecurrence rate is low when basal cell carcinomas treated with micrographic surgery so this treatment modality (when indicated) is also strongly recommended in Iran for the treatment of basal cell carcinoma.

Abstract

Introduction: Radius end fracture is one of the most common fractures of the upper limb, the treatment of which is controversial, and improper treatment can have significant side effects. In this study, we intend to examine the results of treatment with an external fixative method.
method: It was easy to study without control and sampling. The study was performed on 30 fractures (26 patients) for one year, based on radiographs of the fracture site of type 4 universal 5. Surgery with standard techniques was performed under general or regional anesthesia, and patients were followed up for up to one year after surgery and examined for shortness of breath, joint surface angle, range of motion, and pain.
Results: Twenty-four men and two women with a mean age of 5.28 years were examined. In all patients, clinical and radiographic effusion occurred. There were two cases of mild infection at the site of the pin, which were treated with medication. In one case, there was a slight sensation in the sensory branch of the radial nerve, which disappeared after a while, and in no case was there a tendon lesion. The mean deviation to the palm was 6.6.5.5 and the ulnar deviation was 4.5 to 12.5.
There were 4 cases of pain during strenuous activity, 2 cases of mild movement restriction and one case of severe movement restriction.
Conclusion: Compared to other studies, the results of this study are much better in many cases and it is recommended to use this treatment in the treatment of unstable fractures of the lower end of the radius and especially if it develops into the radiocarpal joint.

Abstract

Introduction: Cystic hygroma is a disorder in lymphatic vessel formation that involves the adjacent organs and can affect them due to its fast growing nature . The main treatment for cystic hygroma is surgical intervention that can have many complications after surgery. Treatments other than surgical interventions is the use of sclerosing agents. The goal of this study is to analyze the effect of Beliomycin in treating cystic hygroma . Materials and Methods: This quasi experimental study was carried out clinically at st-al Zahra and Kashanie hospitals of Isfahan from 1372 to 1383. A checklist including age, sex, cyst location, cystic hygroma volume before and after Beliomycin injection and/or surgery, was completed for each patient. Data was analyzed by T and paired T-Tests. p<0.05 was considered meaningful. Results:The study was carried out on 72 patients. 24 patients were treated with Beliomycin and 48 patient by surgery. Patients age was below 1 month up to 18 years old . Cystic hygroma was mainly located at neck region(46.8%). The average size of cystic hygroma was 103.9±29.66cm3 before Beliomycin injection and 34.91 16.19cm3 after that (p=0.004). and 43.511±7.81cm3 before surgery and 1.39±1.39 cm3 after that(p=0.006). The rate of recurrence of lymphingoma in the surgery treated group was 25.1% and in the group treated with Beliomycin was 29.2% with no significant difference. Conclusion: Regarding the considerable decrease in cyst volume after Beliomycin injection and it,s low complication compared to surgery, this method can be used as a primary treatment or supplementary to surgery.

Abstract

Introduction: Flexor tendon entrapment of the digits (FTED) is a disorder characterized by snapping or locking of the thumb or fingers (with or without pain) and called trigger finger. Corticosteroid injections are one of the most commonly used treatments for chronic tendon disorders. Despite their popularity, the systematic evidence for their benefits are largely lacking. This study tries to determine the efficacy of local corticosteroid injection in treatment of trigger finger. Materials and Methods: This is a clinical trial research. Variables including local tenderness, trigerring stage, pain during isometric flexion and passive stretching of the tendon (based on VAS) were evaluated before local injection of corticosteroid and then 3 weeks, 3 months and 6 months after the injection. Data was collected by special forms and analyzed using Chi square and ANOVA Tests. Results: The difference between persence of A1 pulley tenderness in 4 examinations was significant (p<0.0001). The difference between pain induced by isometric flexion and pain induced by stretching the tendon passively in extension was also significant (both p<0.0001). The difference between frequency distribution of triggering was significant (p<0.0001). Patients satisfaction was 90% . Conclusion: The rate of success in local corticosteroid injection was 90% (only with one injection). The high rate of success and low side effects, make this method a suitable treatment for trigger finger.

Abstract

Introduction: Clubfoot is one of the most common foot deformities in children. The initial treatment of clubfoot is nonsurgical. The succes rate of this treatment is 5-80%. If clubfoot does not respond to this treatment, surgery is indicated. Surgical treatment of clubfoot has several complications. The preferred method of surgical release in textbooks is a modified Mc Kay procedure with Cincinnati incision but it may have various complications such necrosis, excessive scar, infection, dehiscence and recurrence. The purpose of this article is to investigate surgical treatment of clubfoot with two incision procedure instead of Cincinnati incision. Materials and Methods: In this descriptive study 50 children (81 feet) with clubfoot disease who did not respond to nonsurgical treatment, since 1999 until 2002, in Al-Zahra hospital were selected and underwent soft tissue release procedure by posteromedial and lateral incisions. After operation they were followed for at least two years. Every six months patients were assessed for early postoperative complications, clinical and radiologic recurrence. Data was presented using descriptive statistics. Results: 74% of patients were male. Their mean age was 3.40.69. There was positive family history in 14% of patients. Clinical recurrence was seen in 6 patients, (9 feet) (5 male, one female) that all had bilateral involvement. The most common type of recurrence was metatarsus adductus. There was no skin necrosis or deep wound infection after surgery but 2 cases of superficial infection was seen which were treated by drugs. Conclusion: Regarding the excellent results of this procedure and obtained correction and the least skin complications in comparison to textbooks we suggest the two incision procedure instead of Cincinnati incision in treatment of most club foots

Abstract

Background: Bacterial vaginosis is one of the most common infections in women at reproductive age. Although metronidazole is recommended as the first-line treatment, it has various side effects which make it difficult for patients to continue the treatment. Thus, the need is felt for finding a medication with fewer side effects. The aim of this study is to compare the effects of micosin vaginal cream (made of garlic) and metronidazole vaginal gel on treatment of patients with bacterial vaginosis. Materials and Methods: This study was a clinical trial which was conducted on 100 married women, aged 18-44, whose infection with bacterial vaginosis was diagnosed through clinical Amsel criteria. The participants were randomly divided into two groups of 50 persons each: Micosin vaginal cream and metronidazole vaginal gel. Patients identified with tricamona or candidiadis infections were excluded from the study. Treatment period in each group lasted for seven days. Clinical Amsel criteria and patient complaints were again checked 2 to 7 days after completion of the treatment period, and the side-effects were registered. Results: Following the treatment with micosin vaginal cream and metronidazole vaginal gel, patient complaints and clinical Amsel criteria showed a significant decrease (p<0.05), in a way that clinical recovery rates in micosin and metronidazole groups were 80% and 70%, respectively. Conclusion: Micosin vaginal cream seems to be an appropriate alternative for metronidazole vaginal gel in treatment of bacterial vaginosis.

Abstract

Background: Quran views sleep as a divine sign with deep meaning and interpretation. The aim of this study was to investigate the content of dreams from the perspective of Quran and psychology, as an appropriate method for understanding human characteristics and presenting a proper treatment approach. Materials and Methods: The present study is a descriptive, content analysis one. First a collection of psychology and interpretation books on this issue were considered. Then 75 students at Arak University of Medical Sciences were asked to report their dreams on daily or weekly basis which totaled 5688 dreams over a 6.5 month period. The dreams were analyzed using content analysis method and descriptive statistics, including the number of dreams, age, mean, and frequency of the reported parameters. Results: Noticing the nature of dreams, the interpretation of their content and concepts is of significance to the understanding of human traits and provision of treatment methods. The content of the reported dreams were, respectively, indicative of a high percentage of ethnic (93.33%), university and professors (89.33%), family (88%), religious beliefs (86.66%), friends (86%), nightmares (66.66%) returning to the past (61.33%), lucid dreaming (42.7%), and neurosis (41.33%). Conclusion: In the view of commentators on divine verses and psychologists, the elements present in the content of dreams can be utilized in obtaining a better understanding of the unconscious stream of human mind, knowing more about human beings, and treating mental disorders. The difference between these two perspectives, religious and psychological, is in dreams known as "true dreams" which are emphasized in Quran and Islamic sources, while psychology has failed to recognize them.

Abstract

Background: According to the toxoplasmic retinochoroiditis leading to loss of central vision, corneal opacity, tearing, photophobia, and is, therefore early treatment is very important. This study aimed to evaluate the efficacy of intravitreal injection of toxoplasmic retinochoroditis clindamycin in comparison with conventional therapy (oral drug) was performed.

Materials and Methods: In this clinical trial, target population was all patients with the toxoplasmic retinochoroiditis referred to clinics in ophthalmology Arak city, that stratified randomly into two groups, interventional group “A” was received treatment with intravitreal injection clindamaycin " and control group “B” was received standard oral treatment (Pyrimethamine and sulfadiazine and clindamaycin). Tool for data gathering was questionnaires and medical records of patients in which visual acuity based on the Senllene Chart and retinal thickness with use tomography layers of the retina (OCT). Results of measurement were recorded by specialist retina before and after intervention (weekly and monthly until complete resolution of lesions in retina) during one year. The data entered into the SPSS 16 software and after matching age &sex of patients, was final analysis the using descriptive and inferential tests such as t-test was performed.

Results: Of the 26 patients with toxoplasmic retinochoroditis, 16 (61.5%), urban and number 10 (38.5%) were rural. The average improvement in visual acuity between the two groups in mean time to lesion healing (A) and (B) was different. The visual acuity in before and after treatment (separation of treatment) was significant difference in both groups (p<0.05). Also central macular thickness (in patients with toxoplasmic retinochoroditis) between before and after treatment in each group was different (p= 0.001), but the changes mean central macular thickness (in cases of toxoplasmic retinochoroditis) There was no significant difference between treatments (p=0.452).

Conclusion: Although any two methods of treatment are effective, but intravitreal injection clindamaycin method due to shorter lesion healing time and increase higher visual acuity, is better than the alternative similar way .

Abstract

Background: Treatment failure and relapse is a major problem in the treatment and control of brucellosis. The present study directed to determine risk factors for failure of treatment and relapse in patients treated for brucellosis.

Materials and Methods: This study was a descriptive - analytic and prospective study and were conducted in 72 patients with acute brucellosis.Patients were followed up during treatment and for six months after completion of therapy, and patients with treatment failure or relapse were analyzed. All data analyzed using SPSS software and P-value of less than 0.05 was considered significant.

Results: The mean value of age in patients was 40.2 ± 16.5 years. Treatment failures was 6.9% and the relapse at the end of the ninth month was 12.5% that recurrence of symptoms were associated with increased titers of serological tests and 80.6 percent had successful treatment. In this study gender of male (P = 0.026), occupational exposure (P = 0.005), delayed treatment in less than two weeks (P = 0.016), hepatosplenomegaly (P = 0.003), thrombocytopenia (P = 0.023), CRP &ge +2 (P = 0.017) and Wright &ge 1/320 and 2-ME &ge 1.160 at the end of the sixth week of treatment (P = 0.004 and P = 0.010) were risk factors of treatment failure and relapse in brucellosis.

Conclusion: The diagnosis and treatment of relapse and treatment failure in acute brucellosis is not clear, therefore, the prediction of relapse may be useful in preventing recurrence and treatment of patients.

Abstract

Background: Vesicoureteral Reflux (VUR) is the most common urologic anomaly in children. In spite of prescribing prophylactic antibiotics in children with VUR, in some cases breakthrough infection (BTI) occurs while receiving prophylactic antibiotics which may cause pyelonephritis that can ultimately lead in renal scarring.

Materials and Methods: In this discreptive-analytic study, 288 children with primary vesicoureteral reflux under Cotrimoxazole(2mg/kg) treatment have been under supervision for duration of at least one year. Based on the collected data, predictive effect of some factors like gender, mean age of VUR diagnosis, VUR grade, unilateral versus bilateral and presence of abnormal renal scar on the breakthrough infection under prophylactic treatment, were examined.

Results: Breakthrough infection while receiving prophylactic antibiotics was observed among 111(38.54%) patients consisting of 88 girls (79.28%) and 23 boys (20.72%). The moderate to high VUR grades (grade III-V), presence of renal scar and female gender were found to be the important risk factors for BTI. However, no statistically significant relationship between mean age of VUR diagnosis and unilateral versus bilateral VUR with BTI was found.

Conclusion: Results of the current study will help improving parents' and physicians' awareness of the risk factors associated with BTI which may potentially lead to renal damage.

Abstract

Background: Allergic rhinitis is a common disease which is present in 20% of general population. Major symptoms include sneezing, rhinorrhea, nasal congestion, and nasal pruritus. It seems that tricyclic antidepressants blocking histamine receptors may be used as an effective treatment in allergic rhinitis.

Materials and Methods: In this clinical trial study, 84 patients with allergic rhinitis entered the study and randomly divided into two groups. Patients of 1st group received cetirizine and 2nd group received doxepin for 2 weeks. After 2 weeks patients were evaluated about sneezing, rhinorrhea, nasal congestion, and nasal pruritus.

Results: The results of our study showed that clinical score of patients after 2 weeks was not different in both groups (p=0.261). The only symptom that was affected by the kind of treatment and was significantly different between groups was sneezing (p=0.005).

Conclusion: It seems that there is not much difference in using cetirizine and doxepin in treatment of seasonal allergic rhinitis sympotoms. It is recommended that future studies use TCAs with more potent blocking anti-histamine receptors feature and on more samples.

Abstract

  Background: The prevalence of constipation in childhood is 0.7% to 29.6%. Inorganic causes are considered as the most common cause of constipation in children. Polyethylene glycol (PEG) is the most effective and safest laxatives which is usable in children in the long-term. This study was conducted to evaluate and compare the effect of PEG treatment and probiotic bacilluscoagulans and bifidobacterium and probiotic to enhance the growth of probiotics.

  Materials and Methods: In this double blind clinical trial study(interventional study), 120 children aged 2-16 years with chronic functional constipation enrolled the study based on ROME III criteria. The bowels became empty by using liquid paraffin. Then, children were randomly divided into three groups of polyethylene glycol+placebo and Probiotics+placebo and polyethylene glycol+probiotics recipients. After 6 weeks of treatment, treatment success rates between the three groups were compared before and after the study Data analyzed by SPSS 20 software.

  Results: The results of the study conducted on the three groups for treatment of constipation showed that the effect of polyethylene glycol and probiotic on treatment was considerable before and after treatment but the levels of effect was similar in the comparison of groups. The simultaneous use of two drugs was more effective than a single drug.

Conclusion: Overall, the results of our study showed that concurrent use of polyethylene glycol and probiotics is much more effective in the treatment of constipation.

Abstract

Background: The growth of population, improvement of quality of life and the development of industries have led to increase in the rate of urban and industrial waste. As the leachate of the waste has a lot of pollution, influences harmfully human health and the environment. Researches have shown that the advanced oxidation processes (AOPs) such as Fenton and Fenton-related processes can reduce chemical oxygen demand (COD) of the leachate effectively.

Materials and Methods: In this paper, the rate of decrease in the total suspended solids (TSS) of leachate from a composting facility in Isfahan was studied using electrochemical, Fenton and electro-Fenton processes. These processes were conducted at reaction times 0, 20, 40, and 60 minutes, with the currents of 0.5, 1 and 1.5A and hydrogen peroxide dosages 1000, 2000, and 3000 mg/L.

Results: In the three mentioned processes, the most TSS removal was observed at the first 40 minute of the reactions. Among the studied processes, the electro-Fenton removed up to 92.4% of the TSS and was recognized as the most effective method. Furthermore, electrochemical and Fenton removed 41.7% and 60.3% of the TSS, respectively.

Conclusion: Therefore, decreasing the TSS of leachate could change its qualities and reduce the leachate pollution and the adverse environmental effects.

  1. Abstract
  2. Background: Students face a lot of emotional problems and psychological stress that affect their individual and social adaptation as well as their quality of life. Therefore, examining treatment models for these problems is very important. One of these models, the Fractal Diagnostic Treatment Model, is based on emotional regulation skills for a wide range of emotional disorders that can be used properly. The purpose of this study was to investigate the effectiveness of integrated diagnostic therapy on individual and social adaptations and emotional adjustment.
  3. Materials and Methods: A total of 70 female students were selected and assigned into two diagnostic groups (35 patients) and control (35 people). The experimental group received 12 sessions of diagnostic diagnosis weekly. Data were gathered in this study by Social Compliance Scale and Graz's Regulatory Emotion Questionnaire. Data were analyzed using descriptive statistics and multivariate covariance analysis (MANCOVA).
  4. Results: The results showed that transdiagnostic treatment focused on the dimensions of emotional regulation, including: refusal of emotional responses (F = 120.69, p < 0.01), impulse control problems (F = 14.57, p < 0.01), lack of emotional awareness (F =104.82, p< 0.01), lack of emotional resolution (F=42.64, p< 0.01), participation problems (F = 41.00, p<0.01), and limitations in achieving emotional regulation (F = 85.33, p<0. 01) is effective. Also, the results showed that exacerbation-based fetal diagnostic therapy was effective on individual adaptations (F = 146.76, p < 0.01) and social (F = 85.02, p<0.01).
  5. Conclusion: Regarding the effect of Fract-Intervention therapy based on emotional adjustment on personal and social adaptation and student's emotional adjustment dimensions, these results are applicable to clinical practitioners, counselors and practitioners in academic counseling centers.

Abstract

Hepatitis C is one of the important causes of liver disease in the world. It seems that HCV will emerge as the leading cause of viral hepatitis-related advanced liver diseases and death in the near future. There are approximately 71 million chronically infected individuals worldwide, many of whom are unaware of their infection (1).
It has been estimated that the prevalence of HCV in the Iranian general population is less than 0.5%. In Iran, the average prevalence of HCV is among thalassemia patients (16.6%), hemophilia patient (54%), individuals under dialysis (8.3%) and among injection drug users (51.4 percent).
After screening of blood donors for HCV in Iran, the burden of HCV infection decreased significantly in hemophilia, thalassemia and patients on hemodialysis. Unfortunately, injecting illicit drugs still continues to be a major source of infection in Iran (2, 3).
Iran has the lowest prevalence for HCV infection in the Middle East. Countries such as Pakistan and Azerbaijan with high prevalence of HCV infection are neighbors of Iran (2).
The main populations at risk of HCV infection in Iran include intravenous drug users (IDUs) followed by people with tattoos, use of common razor, multi partner, homosexuality, receiving blood, and patients on hemodialysis (2).
Clinical care for patients with hepatitis c infection has advanced considerably thanks to an enhanced understanding of the pathophysiology of the disease and because of developments in diagnostic procedures and improvement in therapy and prevention, and HCV elimination has been considered by the World Health Organization till 2030 (2,3).
Screening and treating patients is necessary to eradicate HCV, So, EIA test is used for initial screening and detecting antibody against hepatitis C. Rapid diagnostic tests (RDTs) using serum, plasma, finger stick, whole blood or saliva as matrices can be used for initial screening. If anti-HCV antibodies are detected, the presence of HCV RNA or alternatively HCV core antigen in serum or plasma should be determined to identify patients with ongoing infection. Although the sensitivity of the core antigen assay is less than HCV RNA assay, but because of low cost and good sensitivity, it is a valuable test for HCV. The positive Anti HCV by EIA and negative PCR may be occurred by following reasons: 1-false positive 2-spontaneous viral clearance 3- treatment –induced viral clearance, 4- low levels of virus DNA in the Blood that is not determined by PCR. Following spontaneous or treatment –induced viral clearance, anti HCV antibodies may be persist lifelong. Thus, the follow of treated patient use of PCR or core Ag is necessary (1). HCV has a high rate of genetic heterogeneity (1-7 genotype), therefore, no vaccine to prevent this infection today. Genotype 1a and 3a are the most prevalent genotypes in Iran. HCV reinfection can occur after spontaneous or treatment induced viral clearance, essentially if patient at high risk of infection and re exposure (4).
Strategies to promote diagnosis, screening, and treatment should be targeted to high-risk groups rather than the general population. Annual screening is recommended for Individuals with a history of injecting illicit drug. In the past, treatment of HCV was interferon and ribavirin for 24 to 48 weeks. This treatment regimen associated with low response to treatment, high drug complication and high drug cost. In 2011, protease inhibitors, the first generation of DAAs (Telaprevir and Boceprevir), were emerged as the third component of the standard of care. These drugs had a lot of complications such as drug-drug interactions, severe skin rashes/pruritus and anemia. In 2013, Sofosbuvir, a new DAA, was introduced for treatment of HCV infection. SOF-containing regimens had a shorter duration of therapy, with fewer side effects in comparison with protease inhibitor-based triple therapy (5).
At present, in Iran, the basis of treatment is sofosbovir 400 milligram that combined with second drug daclatasvir (60 mg) or velpatasvir in pan genotype and or ledipasvir (90 mg) in genotype 1a. These drugs exist in separated or combination form with different brand names. In fact, the patient with hepatitis C in both treatment-naive and non-cirrhotic, taking a combination pill daily for 12 weeks associated with high treatment response. However, in cirrhotic patients or patients with previous treatment experience, treatment prolongs 24 weeks or ribavirin (1000 -1200 mg, 5-6 200mg tablets) is added to 12 weeks of treatment according patient weight. Accurate assessment of liver fibrosis and cirrhosis is essential for predicting prognosis and for planning treatment duration and adding RBV to the standard therapy of patients with chronic HCV infection. So, percutaneous liver biopsy or elastography non-invasive methods have been considered as the gold standard for assessing hepatic fibrosis. If biopsy or elastography not available, platelet count, liver sonography and liver enzyme level is helpful for determination of liver fibrosis (6).
In EASL Recommendations on Treatment of Hepatitis C 2018, other drugs of DAAs like pibrentasvir, glecaprevir, elbatasvir and grazoprevir are recommended. Also 8, 16 and 28 weeks of treatments are suggested in special cases and treatment without sofosbovir is mentioned (1).
Determination of viral load by quantitative PCR and genotyping of HCV recommend before the treatment, if viral load and genotyping is not available, qualitative PCR without genotyping is sufficient for treatment with pan genotyping drugs (1, 5).
New treatments are free-INF and these drugs have low cost and low adverse effect (5, 7). Todays, HCV is treated very simply by consuming only one pill daily for 12 weeks. Sustained viral response (SVR) that defined negative PCR 12-24 weeks after discontinuing treatment occurred in more than 90% of patients (1, 4). In patients with cirrhosis, despite SVR, sonography of liver and αFP level test for screening of liver malignancy is recommended every 6 months (1).
It seems that the best strategy for HCV prevention in the community is increasing case finding and therapy with the ultimate goal of stopping the vicious cycle in the community. Todays, there is no vaccine for HCV prevention yet. The incidence of HCV infection should be reduced by providing safe blood transfusion and medical procedures in hospitals and out-patient clinics, increasing people awareness and public education regarding the risks of exposure such as unsafe tattooing and unsafe sexual contacts and finally implementation of harm reduction for IDUs (1, 5).

Abstract

Nephrotic syndrome
Nephrotic syndrome is a manifestation of glomerular disease as a proteinuria in the nephrotic and triad of hypoalbuminemia, edema, hyperlipidemia, and high protein in the urine. Nephrotic proteinuria is defined as protein excretion of more than 40 mg/m2 of body surface per hour or protein to creatinine ratio of more than 2-3 at the first morning urine sample. Its annual incidence in most western countries is 2-3 cases per 100000 children per year, and in developing countries it is often higher due to malaria (1). New findings in this area are often about treatment, which are evaluated and reviewed in following.

Abstract

Background and Aim: Coronavirus Disease 2019 (COVID-19) is one of the most important viral diseases in the current decade which has caused widespread crisis worldwide. The disease was first reported on December 8, 2019 in Wuhan, Hubei Province, China, in the patients with acute respiratory distress syndrome. On January 8, 2020, the Centers for Disease Control and Prevention in China identified the virus, and it was named 2019-nCoV by the World Health Organization (WHO). The name of the disease was later changed to COVID-19. According to the International Committee on Taxonomy of Viruses, the virus is called SARS-CoV-2 which belongs to the family of Coronaviridae. The viruses of this family have caused outbreaks in several countries (SARS in 2003 and MERS in 2013) which have led to death and economic loss. 
Methods & Materials: In this review study, COVID-19 was studied from various aspects including evolutionary process and molecular biology of its virus. The selected articles were examined based on the information available in the WHO database. SARS-CoV-2 proteins were identified molecularly and functionally using data analysis and bioinformatics methods, and then related drugs and their effects on virus replication and inhibition were investigated.
Ethical Considerations: All ethical principles were observed in this study.
Results: Studies on the structure of SARS-CoV-2 and drug therapies to inhibit the disease progression showed that the use of different pharmaceutical strategies is effective in treating COVID-19 depending on the progression of the disease. Molecular studies showed that the use of nucleoside analogues and protease inhibitors is effective in the course of the disease and intravenous immunoglobulin, aminoquinoline compounds, TMPRSS2 inhibitors and viral S protein can be effective in the early stages of disease.
Conclusion: In order to control COVID-19, it is very important to study the structure of SARS-CoV-2 virus and its biology in the body. It is essential to identify the drugs that affect the virus based on its biological structure. Due to the structural changes of the virus and successive mutations in the virus genome as well as the emergence of resistant strains or highly contagious strains, further studies on the structure of SARS-CoV-2 and its changes in the body are recommended for designing pharmaceutical and therapeutic strategies. These strategies varies according to the stage of the disease, such that some drugs prevent the virus from entering the target cells in the early stages of the disease and other drugs, in combination with the virus’ surface glycoproteins, prevent the virus antigen from binding to receptors in the host cells. In the late stages of the disease, antiviral drugs including protease inhibitors and nucleoside analogues, interfere with the replication and structure of the virus. Due to intermittent changes in the virus and the development of drug-resistant viruses, it is important to continuously review virological and clinical studies and the performance of existing drugs against SARS-CoV-2.

Abstract

Background and Aim: Coronaviruses are a large family of viruses that cause disease in humans and animals. Coronavirus Disease 2019 (COVID-19) is an acute respiratory infectious disease caused by a new coronavirus. The World Health Organization has declared this infectious disease as a global pandemic.
Objective: This study aims to review the latest research advances in genetics, pathogenicity, and clinical features of COVID-19, as well as current therapies to combat this disease.
Methods & Materials: This is a systematic review study on articles published from 2010 to 2020 by searching in reputable databases such as PubMed, Scopus, Google Scholar, Web of Science, and ScienceDirect.
Ethical Considerations: Ethical principles have been observed in accordance with the guidelines of the National Ethics Committee and the COPE regulations.
Results: Examining the genome and genetic studies of the virus, it can be said that there are many similarities between different coronavirus types, but there are differences in their genomic and phenotypic structures that can affect their pathogenesis. Re-use of existing therapeutic drugs, previously designed for other infections and viral pathologies is currently the only practical approach to fight COVID-19. The tests for SARS-CoV-2 genome-specific vaccines and the therapeutic antibodies are currently being tested, but they require a long-term process and complete safety testing.
Conclusion: Rapid diagnosis of SARS-CoV-2 infection is the basis of disease control. There is currently no specific antiviral drug approved for SARS-CoV-2 infection. Therefore, preventive measures are necessary to stop and control the spread of COVID-19, according to genetic studies and the obtaining knowledge of the molecular mechanism of this virus.
