Global Spine J 2021 Apr 20:21925682211005406. Epub 2021 Apr 20.

Sina Trauma and Surgery Research Center, Tehran University of Medical Sciences, Tehran, Iran.

Study Design: Scoping review.

Objective: Regarding that inappropriate medical care approaches, absence of rehabilitation services, and existing barriers in physical, social, and policy environments lead to poor outcomes in individuals with spinal cord injury (SCI) and provision for appropriate interventions and care must be created by health policymakers, we conducted this scoping review to investigate how policymakers can be persuaded to set new plans for individuals with SCI.

Methods: This review was performed according to Arksey and O'Malley's framework. PubMed was searched in February2019 without language limitation. We looked for other potential gray literature sources and some professional websites. References sections of selected articles were also scanned for other relevant literature.

Results: We included literature that met inclusion criteria to answer our research question. The literature was divided into 3 categories. The first category included economic impact of SCI. The second category included the role of research and developing research strategy. The third category included effective interaction and communication with policymakers.

Conclusion: It is essential to consider multiple factors for influencing policymakers' decisions. These factors include knowing how to communicate with policymakers and presenting constructive ideas, providing a source of valid, reliable, and consistent data, considering the role of patients' advocacy groups and Non-Governmental Organizations (NGOs), and presentation of the importance of early intervention in reducing healthcare system costs. Ultimately, the goal is to have a comprehensive and flexible plan for influencing policymakers.

Electronic address:

Background: Protective helmets may reduce the risk of death and head injury in motorcycle collisions. However, there remains a large gap in knowledge regarding the effectiveness of different types of helmets in preventing injuries.

Objective: To explore and evaluate the effectiveness of different types of motorcycle helmets; that is the association between different helmet types and the incidence and severity of head, neck, and facial injuries among motorcyclists. Also, to explore the effect of different helmet types on riders.

Methods: A systematic search of different scientific databases was conducted from 1965 to April 2019. A scoping review was performed on the included articles. Eligible articles were included regarding defined criteria. Study characteristics, helmet types, fixation status, retention system, the prevention of injury or reduction of its severity were extracted.

Results: A total of 137 studies were included. There was very limited evidence for the better protection of full-face helmets from head and facial injury compared to open-face and half-coverage helmets. There was however scarce evidence for the superiority of a certain helmet type over others in terms of protection from neck injury. The retention system and the fixation status of helmets were two important factors affecting the risk of head and brain injury in motorcyclists. Helmets could also affect and limit the riders in terms of vision, hearing, and ventilation. Multiple solutions have been discussed to mitigate these effects.

Conclusion: Full-face helmets may protect head and face in motorcycle riders more than open-face and half-coverage helmets, but there is not enough evidence for better neck protection among these three helmet types. Helmets can affect the rider's vision, hearing, and ventilation. When designing a helmet, all of these factors should be taken into account.

Association of anthropometric indices with cardiovascular disease risk factors among adults: a study in Iran.

Eur J Cardiovasc Nurs 2020 Dec 4. Epub 2020 Dec 4.

Liver and Pancreatobiliary Diseases Research Center, Digestive Diseases Research Institute, Tehran University of Medical Sciences, Shariati Hospital, Digestive Diseases Research Institute, North Kargar Street, Tehran 1411713135, Iran.

Aims: Cardiovascular diseases (CVDs) are the leading cause of death in the world. Many modifiable risk factors have been reported to synergistically act in the development of CVDs. We aimed to compare the predictive power of anthropometric indices, as well as to provide the best cut-off point for these indicators in a large population of Iranian people for the prediction of CVDs and CVD risk factors.

Methods And Results: All the data used in the present study were obtained from Khuzestan comprehensive health study (KCHS). Anthropometric indices, including BMI (body mass index), WC (waist circumference), HC (hip circumference), WHR (waist-to-hip ratio), WHtR (waist-to-height ratio), ABSI (a body shape index), as well as CVD risk factors [dyslipidaemia, abnormal blood pressure (BP), and hyperglycaemia] were recorded among 30 429 participants. WHtR had the highest adjusted odds ratios amongst anthropometric indices for all the risk factors and CVDs. WC had the highest predictive power for dyslipidaemia and hyperglycaemia [area under the curve (AUC) = 0.622, 0.563; specificity 61%, 59%; sensitivity 69%, 60%; cut-off point 87.95, 92.95 cm, respectively], while WHtR had the highest discriminatory power for abnormal BP (AUC = 0.585; specificity 60%; sensitivity 65%; cut-off point 0.575) and WHR tended to be the best predictor of CVDs (AUC = 0.527; specificity 58%; sensitivity 64%; cut-off point 0.915).

Conclusion: In this study, we depicted a picture of the Iranian population in terms of anthropometric measurement and its association with CVD risk factors and CVDs. Different anthropometric indices showed different predictive power for CVD risk factors in the Iranian population.

Retinal changes in patients with angina pectoris and anginal equivalents: a study of patients with normal coronary angiography.

Rom J Intern Med 2021 Jun 8;59(2):174-179. Epub 2021 May 8.

Cardiovascular Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Approximately 10-30% of the patients with typical symptoms of angina pectoris have normal angiography showing normal macrovasculature. In these patients, however, the microvascular problems should be monitored. Hence, the main aim of this study is to evaluate retinal changes in normal angiographic patients. In this descriptive cross-sectional study, 60 normal angiographic patients with typical chest pain or anginal equivalents visiting Modarres Hospital Cardiology Research Center between 2018 and 2019 were enrolled and retinal changes were determined in Labbafinejad Hospital by Optical Coherence Tomography Angiography using Foveal Avascular Zone (FAZ), Superficial Vascular Density (SVD), and Deep Vascular Density (DVD). The results of this study demonstrated that FAZ was normal in all subjects, but SVD and DVD were abnormal in 45% and 8.3%, respectively. Totally, 18.5% and 66.7% showed abnormal SVD among stable angina (SA) and unstable angina (UA) cases, respectively (P < 0.001). There was no statistically significant difference between abnormal DVD in SA and UA cases (P = 0.058). Abnormal SVD was significantly more common among diabetic patients (P < 0.001), while DVD was not related to diabetes presence in the study population (P > 0.05). Moreover, abnormal SVD was more common among patients with chest pain (P = 0.036), while there was no significant difference for DVD (P = 0.371). Interestingly, abnormal ECG was associated with both abnormal DVD and SVD. The results of this study showed that nearly half of the patients with angina pectoris or anginal equivalents who revealed normal angiographic findings may suffer from retinal changes. Thus, retinal assessment is needed in these patients to evaluate microvascular changes.

The impact of air pollution on skin and related disorders: A comprehensive review.

Dermatol Ther 2021 Mar 12;34(2):e14840. Epub 2021 Feb 12.

Skin Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

As the largest organ in the body, human skin is constantly exposed to harmful compounds existing in the surrounding environment as the first-line barrier. Studies have indicated that exposure to high concentrations of many environmental factors, such as ultraviolet (UV) radiation, outdoor air pollutants, including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), particulate matter (PM), heavy metals, gaseous pollutants, such as carbon monoxide (CO), nitric oxides (NO ), sulfur oxide (SO ), ozone (O ), and indoor air pollutants (solid fuels consumption), might interrupt the skin's normal barrier function. Besides, the intensity of the pollutants and the length of exposure might be a contributing factor. Air pollutants are believed to induce or exacerbate a range of skin conditions, such as aging, inflammatory diseases (atopic dermatitis, cellulitis, and psoriasis), acne, hair loss, and even skin cancers (mainly melanoma and Squamous Cell Carcinoma) through various mechanisms. The interaction between pollutants and the skin might differ based on each agent's particular characteristics. Also, damaging the skin barrier seems to be closely related to the increased production of reactive oxygen species (ROS), induction of oxidative stress, activation of aryl hydrocarbon receptor (AhR), and inflammatory cytokines. This article reviews recent studies on the correlation between air pollutants and skin diseases, along with related mechanisms.

Clinical features and short-term outcomes of COVID-19 in Tehran, Iran: An analysis of mortality and hospital stay.

Acta Biomed 2020 11 10;91(4):e2020147. Epub 2020 Nov 10.

Array.

Background The sudden outbreak of the COVID-19 disease originated in Wuhan, China, in December 2019. There have been few reports of the clinical course of the disease, but detailed information on the risk factors for increased hospital stay and mortality is not available. In this study, we aimed to present the details of 53 confirmed COVID-19 cases to share the clinical course and the risk factors for longer hospital stay and death. Methods In this study, we enrolled fifty-three patients with confirmed COVID-19 infection from a referral academic hospital in Tehran, Iran admitted between March and April 2020. Patients' demographics, laboratory tests, treatments, length of hospital stay (LOHS), and final outcome were recorded and analyzed. Results Fifty-three patients were included in this study. The higher LOHS was associated with clinical symptoms, including hemoptysis (IRR= 0.73, P-value= 0.02), diarrhea (IRR= 0.78, P-value= 0.01), headache (IRR= 0.81, P-value= 0.05), and dry cough (IRR= 0.82, P-value= 0.05). Mortality was associated with older age(Odds ratio=1.148, 95%CI=1.032-1.276), lower calcium level (Odds ratio=0.087, 95%CI=0.010-0.788), lower serum albumin (Odds ratio=0.036, 95%CI=0.002-0.655), as well as increased level of neutrophil/lymphocyte ratio (NLR) (Odds ratio=1.468, 95%CI=1.086-1.985), lactate dehydrogenase (LDH) (Odds ratio=1.004, 95%CI=1.000-1.007), and urea (Odds ratio=1.023, 95%CI=1.006-1.039).  Conclusion Our study identified that decreased levels of O2saturation, platelet count, calcium, albumin, and increased NLR, LDH, urea, and old age were correlated with mortality. Also, LOHS was significantly associated with clinical findings, such as hemoptysis and diarrhea.

SARS-CoV-2: An insight into detection tools.

Infect Disord Drug Targets 2021 Jan 4. Epub 2021 Jan 4.

Department of Pathology, Shariati Hospital, Tehran University of Medical Sciences, Tehran. Iran.

The novel coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), was announced as a pandemic in March 2020. Different diagnostic laboratory tests have been used to detect the infection. Each diagnostic tool, such as Chest Computed tomography (CT) imaging, genome sequencing, nucleic acid amplification methods, whole genome sequencing, microarray, and serology testing have several advantages and disadvantages. Nucleic acid amplification methods are better diagnostic tools for the detection of SARS-CoV-2 in early stages of the infection, while serological tests are more appropriate for the recognition of previously infected patients. In this review, we will briefly consider each diagnostic method, and discuss its pros and cons.

Ethical considerations in neurology during the COVID-19 pandemic.

Neurol Sci 2021 Feb 2;42(2):437-444. Epub 2021 Jan 2.

Department of Neurology, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Coronavirus disease 2019 (COVID-19) pandemic has struck many countries and caused a great number of infected cases and death. Healthcare system across all countries is dealing with the increasing medical, social, and legal issues caused by the COVID-19 pandemic, and the standards of care are being altered. Admittedly, neurology units have been influenced greatly since the first days, as aggressive policies adopted by many hospitals caused eventual shut down of numerous neurologic wards. Considering these drastic alterations, traditional ethical principles have to be integrated with state-of-the-art ethical considerations. This review will consider different ethical aspects of care in neurologic patients during COVID-19 and how this challenging situation has affected standards of care in these patients.

Protective effect of modafinil on skin flap survival in the experimental random-pattern skin flap model in rats: The role of ATP-sensitive potassium channels and nitric oxide pathway.

J Plast Reconstr Aesthet Surg 2020 Nov 10. Epub 2020 Nov 10.

Experimental Medicine Research Center, Tehran University of Medical Sciences, Tehran, Iran; Department of Pharmacology, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran. Electronic address:

Background: The brain-stimulating agent modafinil acts through nitric oxide (NO) and adenosine triphosphate (ATP)-sensitive potassium (K) channels, involved in the skin flap survival (SFS). The main aim of this study was to investigate the efficacy of modafinil on SFS in rats through the involvement of NO pathway and K channels.

Methods: Using controlled experiment study design, we enrolled a sample of Wistar male rats. Different doses of modafinil (10, 25, 50, and 100 mg/kg) were injected intraperitoneally (i.p.) before the surgery. L-NAME (non-selective nitric oxide synthase [NOS] inhibitor), aminoguanidine (inducible NOS inhibitor), and 7-nitroindazole (neuronal NOS inhibitor) were administered prior to modafinil. The role of K channels was determined by coadministering glibenclamide (K channel blocker) or cromakalim (K channel opener) with modafinil. The predictor variables were administration of different doses of modafinil, and the coadministration of modafinil with L-NAME, aminoguanidine, 7-nitroindazole, glibenclamide, and cromakalim. The main outcome variables included the percentage of necrotic area (PNA) in flap tissues, histopathological results, vascular endothelial growth factor (VEGF) immunohistochemical (IHC) staining, and nitrite concentrations. Appropriate statistics were computed considering p-value ≤ 0.05 significant.

Results: Modafinil 25 mg/kg was the most effective dose (PNA: 26 [95% CI: 19-33]) vs. control (PNA: 81 [95% CI: 71-92]) (p< 0.001). All NOS inhibitors significantly reversed the protective effect of modafinil (p< 0.001). Non-effective dose of cromakalim had a synergistic effect with the sub-effective dose of modafinil (10 mg/kg), while glibenclamide reversed the effect of modafinil 25 mg/kg (p< 0.001).

Conclusions: Modafinil increases SFS mediated by NO pathway and K channels, which could therefore be a target to improve SFS.

Ivermectin Increases Random-Pattern Skin Flap Survival in Rats: The Novel Role of GABAergic System.

J Surg Res 2021 03 14;259:431-441. Epub 2020 Oct 14.

Experimental Medicine Research Center, Tehran University of Medical Sciences, Tehran, Iran; Department of Pharmacology, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran. Electronic address:

Background: Ivermectin (IVM) was first used as an antiparasitic agent; however, the role of this drug evolved into a broad spectrum. Many mechanisms have been proposed, including interaction with the GABAergic system. Considering the presence of GABA receptor in the skin tissue and its role in ischemia-reperfusion I/R injury, we aimed to evaluate the effect of IVM through GABA receptors on random-pattern skin flap survival.

Methods: Sixty Wistar male rats were used. Multiple doses of IVM (0.01, 0.05, 0.2, and 0.5 mg/kg) were injected intraperitoneally before the surgery. Baclofen (selective GABA agonist) and bicuculline (selective GABA antagonist) were administered in combination with IVM to assess the role of the GABAergic system. Histopathological evaluations, immunohistochemical staining, quantitative assessment of IL-1β and TNFα, and the expression of GABA α1 subunit and GABA R1 receptors were evaluated in the skin tissue.

Results: IVM 0.05 mg/kg could significantly increase flap survival compared with the control group (P < 0.001). Subeffective dose of baclofen (0.1 mg/kg) had synergistic effect with the subeffective dose of IVM (0.01 mg/kg) (P < 0.001), whereas bicuculline 1 mg/kg reversed the effect of IVM (0.05 mg/kg) (P < 0.001). IVM 0.05 mg/kg could also decrease the IL-1β and TNFα levels and increase the expression of GABA α1 subunit and GABA R1 receptors in the flap tissue compared with the control group.

Conclusions: IVM could improve skin flap survival, probably mediated by the GABAergic pathway. Both GABA and GABA receptors are involved in this process. This finding may repurpose the use of old drug, "Ivermectin."

How to overcome cardiovascular challenges in COVID-19 patients: a guide for common practice.

Acta Biomed 2020 09 7;91(3):e2020021. Epub 2020 Sep 7.

.

The COVID-19 epidemic initially started in Wuhan, China in December 2019 due to SARS-CoV-2. SARS-CoV-2 is genetically similar to the bat beta-coronavirus genus, but the novel specie of this genus can infect humans. The most common clinical features of COVID-19 are fever, cough, myalgia, fatigue, expectoration, and dyspnea. The primary reported mortality rate was about 2-3% in China; however, it reached up to 10% among patients with underlying cardiovascular diseases. The primary epidemiological investigations showed a high prevalence of underlying cardiovascular diseases in more than 40% of infected patients. A high prevalence of hypertension, ischemic heart disease, and diabetes were reported among deceased patients in Italy. Previous experiments in different pandemic situations showed that the cardiovascular system has been affected in many ways. Previous studies on SARS-CoV and MERS-CoV reported that cardiovascular co-morbidities had a direct correlation with the risk of infection, the severity of disease, and the mortality rate. Therefore, brief and available protocols for controlling the negative effects of this novel respiratory infection on the cardiovascular system, especially in a high-risk populations with underlying cardiovascular conditions, is one of the most serious concerns among healthcare providers. Herein, we aimed to review the available data on the cardiac manifestation of COVID-19. Besides, we described useful maps for the better treatment of COVID-19 infection in patients with underlying cardiovascular conditions, as a high-risk group of patients.

Air Pollution and Cardiac Arrhythmias: A Comprehensive Review.

Curr Probl Cardiol 2021 Mar 22;46(3):100649. Epub 2020 Jul 22.

Air pollution is the mixture of some chemical and environmental agents including dust, fumes, gases, particulate matters, and biological materials which can be harmful for the environment and the human body. The increasing trend of the air pollution, especially in developing countries, may exert its detrimental effects on human health. The potentially harmful effects of air pollution on the human health have been recognized and many epidemiological studies have clearly suggested the strong association between air pollution exposure and increased morbidities and mortalities. Air pollutants are classified into gaseous pollutants including carbon mono oxide, nitrogen oxides, ozone and sulfur dioxide, and particulate matters (PMs). All air pollutants have destructive effects on the health systems including cardiovascular system. Many studies have demonstrated the effect of air pollutant on the occurrence of ST elevation myocardial infarction, sudden cardiac death, cardiac arrythmias, and peripheral arterial disease. Recently, some studies suggested that air pollution may be associated with cardiac arrhythmias. In this study, we aimed to comprehensively review the last evidences related to the association of air pollutant and cardiac arrythmias. We found that particulate matters (PM, PM, and UFP) and gaseous air pollutants can exert undesirable effects on cardiac rhythms. Short-term and long-term exposure to the air pollutants can interact with the cardiac rhythms through oxidative stress, autonomic dysfunction, coagulation dysfunction, and inflammation. It seems that particulate matters, especially PM have stronger association with cardiac arrhythmias among all air pollutants. However, future studies are needed to confirm these results.

Pathologic features of COVID-19: A concise review.

Pathol Res Pract 2020 Sep 4;216(9):153097. Epub 2020 Jul 4.

Department of Pathology, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran. Electronic address:

The novel coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), first appeared in December 2019, in Wuhan, China and evolved into a pandemic. As Angiotensin-Converting Enzyme 2 (ACE2) is one of the potential target receptors for SARS-CoV-2 in human body, which is expressed in different tissues, multiple organs might become affected. In the initial phase of the current pandemic, a handful of post-mortem case-series revealed COVID-19-related pathological changes in various organs. Although pathological examination is not a feasible method of diagnosis, it can elucidate pathological changes, pathogenesis of the disease, and the cause of death in COVID-19 cases. Herein, we thoroughly reviewed multiple organs including lung, gastrointestinal tract, liver, kidney, skin, heart, blood, spleen, lymph nodes, brain, blood vessels, and placenta in terms of COVID-19-related pathological alterations. Also, these findings were compared with SARS and MERS infection, wherever applicable. We found a diverse range of pathological changes, some of which resemble those found in SARS and MERS.

CT-scan findings of COVID-19 pneumonia based on the time elapsed from the beginning of symptoms to the CT imaging evaluation: a descriptive study in Iran.

Rom J Intern Med 2020 Dec 17;58(4):242-250. Epub 2020 Dec 17.

Department of Infectious Diseases, School of Medicine, Imam Khomeini Hospital, Tehran University of Medical Sciences, Tehran, Iran.

Coronavirus disease 2019 (COVID-19) was initially detected in Wuhan city, China. Chest CT features of COVID-19 pneumonia have been investigated mostly in China, and there is very little information available on the radiological findings occurring in other populations. In this study, we aimed to describe the characteristics of chest CT findings in confirmed cases of COVID-19 pneumonia in an Iranian population, based on a time classification. Eighty-nine patients with COVID-19 pneumonia, confirmed by a real-time RT-PCR test, who were admitted to non-ICU wards and underwent a chest CT scan were retrospectively enrolled. Descriptive evaluation of radiologic findings was performed using a classification based on the time interval between the initiation of the symptoms and chest CT-scan. The median age of patients was 58.0 years, and the median time interval from the onset of symptoms to CT scan evaluation was 7 days. Most patients had bilateral (94.4%) and multifocal (91.0%) lung involvement with peripheral distribution (60.7%). Also, most patients showed involvement of all five lobes (77.5%). Ground-glass opacities (GGO) (84.3%) and mixed GGO with consolidation (80.9%) were the most common identified patterns. We also found that as the time interval between symptoms and CT scan evaluation increased, the predominant pattern changed from GGO to mixed pattern and then to elongated-containing and band-like-opacities-containing pattern; on the other hand, the percentage of lung involvement increased. Bilateral multifocal GGO, and mixed GGO with consolidation were the most common patterns of COVID-19 pneumonia in our study. However, these patterns might change according to the time interval from symptoms.

Oncoplastic Repair in Breast Conservation: Comprehensive Evaluation of Techniques and Oncologic Outcomes of 937 Patients.

Clin Breast Cancer 2020 12 7;20(6):511-519. Epub 2020 Jun 7.

Division of Pulmonary, Allergy and Critical Care Medicine, Department of Medicine, University of Pittsburgh, Pittsburgh, PA.

Background: Breast-conserving surgery, especially with oncoplastic breast surgery (OBS), is becoming the standard of care in the surgical management of breast cancer. We investigated the applied technique of OBS and oncologic outcomes in a large series of patients.

Patients And Methods: This study was conducted between January 2008 and June 2018 in two centers in Iran. Patients underwent OBS. Early and late postoperative complications, oncologic outcomes, and follow-up data were documented.

Results: Nine hundred thirty-seven patients with a mean ± standard deviation age of 48.1 ± 11.3 underwent OBS. Most of the patients were diagnosed with early-stage disease, of which the most common pathology was invasive ductal carcinoma (83.3%). Lateral oncoplasty was the most commonly used OBS technique (324 cases, 34.6%). The most common complication was seroma formation. Reduction-type OBS technique had the highest rate of complications (13.1%). Thirty-four patients (5.4%) experienced local recurrence, with a median recurrence time of 26.4 months. Nine patients (1.3%) died from cancer recurrence.

Conclusion: OBS is a safe procedure with minor complications and good oncologic outcomes. These techniques can be applied to most patients who are candidates for breast-conserving surgery.

Orbital anatomical parameters affecting outcome of deep lateral orbital wall decompression.

Eur J Ophthalmol 2020 Jul 6:1120672120941433. Epub 2020 Jul 6.

Division of Orbital and Ophthalmic Plastic Surgery, Jules Stein Eye Institute, University of California-Los Angeles, Los Angeles, CA, USA.

Purpose: To determine orbital anatomical parameters that affect surgical outcome of deep lateral orbital wall decompression.

Methods: Twenty orbits of 20 patients with moderate proptosis (maximum 25 mm) due to thyroid eye disease who were stable for at least 6 months were included in this prospective cohort study. Four parameters including lateral orbital wall distance (LOWD), removable surface area (RSA), removable surface length (RSL), and sphenoid door jamb thickness (SDJ) were evaluated by computed tomography (CT) scan prior to surgery in these patients. Deep lateral orbital wall decompression without fat removal was done in all patients. Relationship between all these factors and proptosis reduction, 6 months after surgery was assessed.

Results: Mean proptosis before decompression surgery (mean ± SD) was 23.22 ± 1.19 mm and reduction in Hertel exophthalmometry (mean ± SD) was -3.27 ± 1.03 mm ( = 0.006). Pearson correlation showed that LOWD, RSL, and SDJ had statistically significant correlation with proptosis reduction ( = 0.017, 0.002, and 0.001, respectively.). Linear multivariate regression analysis showed SDJ as the only independent factor in predicting surgical outcome.

Conclusion: several orbital anatomical factors have significant role in predicting surgical outcome following deep lateral wall orbital decompression. Among these parameters, SDJ is an independent factor, whereas LOWD and RSL are dependent factors. Preoperative assessment of the bony sphenoid anatomy may be helpful in predicting the amount of potential decompression.

Association between Serum Vitamin D Level and Echocardiographic Abnormalities in Patients with Thalassemia Major.

Cardiovasc Hematol Disord Drug Targets 2020 ;20(3):214-220

Cardiovascular Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Objectives: Thalassemia major (TM) is one of the most common blood disorders with a high mortality rate due to cardiovascular disease. Vitamin D deficiency has been suggested to implicate in cardiac abnormalities. In this prospective study, we aimed to investigate the relationship between serum levels of vitamin D and tissue Doppler (TD) echocardiographic indices in thalassemia major patients.

Methods: A total of 81 TM patients, including 56 females and 25 males, with a mean age of 27.5± 6.8 years, were enrolled consecutively. Serum levels of vitamin D and other biomedical parameters were measured. Then, all patients were subjected to TD echocardiography. Correlations between the serum parameters and systolic and diastolic indices were examined.

Results: The serum level of vitamin D was correlated with systolic and diastolic indices such as the EF (r= 0.33, P= 0.003) and TD Imaging (TDI)-lateral (r= 0.31, P= 0.005). However, no correlations were observed between vitamin D deficiency and the LV septal and posterior wall thickness, TDIseptal, tricuspid regurgitation peak gradient (TRPG), pulmonary artery systolic pressure (PASP), deceleration time (DT), and propagation velocity (PVcm/s) indices. The results revealed also no linear correlations between serum vitamin D and albumin (r= -0.17, P= 0.06), ALP (r= -0.12, P= 0.14), T4 (r= -0.11, P= 0.16), as well as TSH (r= -0.10, P= 0.19).

Conclusion: It seems that vitamin D deficiency in patients with TM is associated with systolic but not diastolic dysfunctions, possibly as consequences of related biochemical abnormalities.

Double orifice mitral valve in a patient with bicuspid aortic valve and coarctation of the aorta: A rare presentation.

Clin Case Rep 2020 Jun 10;8(6):1021-1024. Epub 2020 Mar 10.

Cardiovascular Research Center Shahid Beheshti University of Medical Sciences Tehran Iran.

Double orifice mitral valve is a rare condition and may be accompanied by a bicuspid aortic valve (sometimes normal functioning) and coarctation of the aorta. Echocardiography is valuable in detecting the accompanied anomalies. Management depends on the severity of mitral valve function and the severity of associated anomalies.

Hand Hygiene Among Health Care Workers During COVID-19 Pandemic: Challenges and Recommendations.

Dermatitis 2020 Jul/Aug;31(4):233-237

From the Skin Research Center, Shahid Beheshti University of Medical Sciences.

In-hospital transmission is one of the main routes of the 2019 novel coronavirus (SARS-CoV-2) spreading among health care workers (HCWs) who are the frontline fighters. However, coming into contact with COVID-19-positive patients is unavoidable. Therefore, hand hygiene is of utmost importance for the prevention of COVID-19 among HCWs. This purpose can be achieved by applying alcohol-based hand rubs, washing hands properly with soap and water, and applying other antiseptic agents. Nevertheless, regular hand hygiene could also be challenging, because water, detergents, and disinfectants may predispose HCWs to hand dermatitis. The current article reviews the risk factors for the development of hand dermatitis, with further focus on the most common agents used among HCWs. In addition, the risk of occupational hand dermatitis for each agent is evaluated to increase awareness of this common condition. Finally, some recommendations are discussed to reduce the effect of hand dermatitis on HCWs.
