RESUMO

ABSTRACT: Tuberculosis (TB) remains a significant global health concern and kills millions of people every year. While TB can affect any organ in the body, breast TB is relatively uncommon. This study presents a comprehensive review of literature spanning 23 years, with a focus on cases of breast TB in Iran. Among the 96 cases found, the majority (89.6%) fell within the age range of 20-60, with a striking prevalence among women (98.9%). Common symptoms included pain and palpable mass, each presenting in approximately 60.4% of cases. Notably, only a quarter of patients had a confirmed history of exposure to a known TB case. Left breast involvement was more prevalent (58.3%), with ipsilateral lymph node enlargement observed in 40.6% of cases. Given the clinical presentation of breast TB, which often leads to misdiagnosis, a significant proportion of cases (68.7%) were diagnosed through excisional biopsy. Following a standard 6-month regimen of anti-TB drugs, relapse occurred in only 4.2% of cases. This study highlights the need for heightened awareness and vigilance in diagnosing breast TB, especially in regions with a high burden. Although breast TB poses diagnostic challenges, with prompt identification and treatment, the prognosis is generally favorable, with a low incidence of relapse.

RESUMO

The correlation between tuberculosis (TB) and lung cancer (LC) in diagnosis, epidemiology, and treatment is still unclear. Based on different cohort and retrospective studies, this correlation could be justified by immune weakness because of exposure to TB which may increase the risk of LC. In this study, we tried to exhibit a prominent connection between TB and LC. The diagnosis and treatment of patients with concomitant TB and LC differ from patients with only one of the diseases. In this review, it was well clarified that the most practical diagnostic method for LC is chest tomography, biopsy, and histopathology, and for pulmonary TB sputum microscopic examination, Autofluorescence bronchoscopy (AFB), culture, and PCR. Also, immunological methods can be a good alternative for differential diagnosis. Most epidemiological studies were about concomitant TB and LC in TB-endemic areas, especially in the Middle East. The most suggested methods for definite treatment of LC are chemotherapy, radiotherapy, and surgery while for TB, a long course of anti-TB therapy can be used. Moreover, immunotherapy is considered a good treatment for lung cancer if the interferon-gamma release assay (IGRA) is negative.

RESUMO

We aimed to review the literature to introduce some effective plant-derived antioxidants to prevent and treat COVID-19. Natural products from plants are excellent sources to be used for such discoveries. Among different plant-derived bioactive substances, components including luteolin, quercetin, glycyrrhizin, andrographolide, patchouli alcohol, baicalin, and baicalein were investigated for several viral infections as well as SARS-COV-2. The mechanisms of effects detected for these agents were related to their antiviral activity through inhibition of viral entry and/or suppuration of virus function. Also, the majority of components exert anti-inflammatory effects and reduce the cytokine storm induced by virus infection. The data from different studies confirmed that these agents may play a critical role against SARS-COVID-2 via direct (antiviral activity) and indirect (antioxidant and anti-inflammatory) mechanisms, suggesting that natural products are a potential option for management of patients with COVID-19 due to the lower side effects and high efficiency.

RESUMO

Various severe acute respiratory syndrome coronavirus 2 vaccines with different platforms have been administered worldwide; however, their effectiveness in critical cases of COVID-19 has remained a concern. In this national cohort study, 24 016 intensive care unit (ICU) coronavirus disease-2019 (COVID-19) admissions were included from January to April 2022. The mortality and length of ICU stay were compared between the vaccinated and unvaccinated patients. A total of 9428 (39.25%) patients were unvaccinated, and 14 588 (60.75%) patients had received at least one dose of the vaccine. Compared with the unvaccinated, the first, second, and third doses of vaccine resulted in 8%, 20%, and 33% lower risk of ICU mortality in the adjusted model, with risk ratio (RR): 0.92, 95% confidence interval (CI): 0.84-1.001, RR: 0.80, 95% CI: 0.77-0.83, and RR: 0.67, 95% CI: 0.64-0.71, respectively. The mean survival time was significantly shorter in the unvaccinated versus the fully vaccinated patients (hazard ratio [HR]: 0.84, 95% CI: 0.80-0.88); p < 0.001). All vaccine platforms successfully decreased the hazard of ICU death compared with the unvaccinated group. The duration of ICU stay was significantly shorter in the fully vaccinated than in unvaccinated group (MD, -0.62, 95% CI: -0.82 to -0.42; p < 0.001). Since COVID-19 vaccination in all doses and platforms has been able to reduce the risk of mortality and length of ICU-stay, universal vaccination is recommended based on vaccine availability.

RESUMO

An outbreak of pneumonia caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is called COVID-19 and has led to a pandemic worldwide. It is reasonable to investigate and control factors affecting disease severity and mortality. The relation between vitamin D and viral pneumonia has been previously reported. Vitamin D deficiency is common and may increase hospital admission and mortality rate in patients with COVID-19. This mini-review examines the pathways that show the association between vitamin D and COVID-19. On the other hand, it deals with the available evidence related to the relationship between vitamin D deficiency and the effect of vitamin D supplementation on the prevalence, severity, and mortality of COVID-19. Also, we described the pathophysiology of the organs' involvement in COVID-19 and the effect of vitamin D on these outcomes. Vitamin D strengthens the innate and adaptive immune system, modulates immune responses, prevents lung and cardiovascular system damage, and reduces thrombotic events. Vitamin D exerts these effects in several pathways. Vitamin D prevents virus entry and replication by maintaining the integrity of the body's physical barrier. Vitamin D reduces the damage to vital organs and thrombotic events by increasing the level of Angiotensin-converting enzyme 2 (ACE2), nitric oxide, and antioxidants or by reducing inflammatory cytokines and free radicals. Sufficient vitamin D may be reduced morbidity and mortality due to COVID-19. However, this issue should be investigated and confirmed by further research in the future.

RESUMO

Background: Pulmonary artery pressure (PAP) is one of the most important and valuable markers in cardiovascular disease, measured by right heart catheterization (RHC) as the gold standard diagnostic modality. However, due to several limitations, such as invasiveness, lack of repeatability, and high health costs, echocardiographic estimation of PAP has been used to substitute RHC for diagnosis and monitoring of this disease. This study aimed to evaluate the correlation of echocardiographic and RHC estimations of systolic PAP. Materials and Methods: In this study, patients, who were referred to Masih Daneshvari Hospital in Tehran, Iran, evaluated by RHC and echocardiography, were selected. The median PAP (mPAP) and systolic PAP (sPAP) for each modality, time interval between the two modalities, sex, and age were extracted from the patients' records. The RHC mPAP data was used for categorization of patients as pulmonary hypertension, while the sPAP data of two modalities was used to assess correlations and define a cut-off point by the ROC analysis. Data analysis was performed using SPSS version 24, and the level of statistical significance was less than 0.05. Results: Seventy-six patients, including 31 males (40.8%) and 45 females (59.2%) with the mean age of 45±14 years, were evaluated in this study. The mean sPAP was 71.98±30.22 mmHg when measured by RHC and 69.75±26.03 mmHg when measured by echocardiography (correlation coefficient=0.805; P<0.001). Agreement between the two measurements was 97%, and the accuracy of echocardiography was 43%. By considering 40 mmHg as the cutoff point, the sensitivity and specificity of echocardiography were estimated at 89.2% and 42.8%, respectively. Based on the ROC analysis, the highest sensitivity (86.7%) and specificity (87.5%) were achieved with an estimated sPAP of 57.5 mmHg. Conclusion: Echocardiography showed a good correlation and agreement with RHC in estimating sPAP; therefore, it is appropriate for screening of patients because of high sensitivity. However, for diagnosis confirmation, monitoring, and follow-up of pulmonary hypertension via echocardiography, high specificity is needed, which can be achieved by considering sPAP of 57.5 mmHg as the cutoff value for pulmonary hypertension.

RESUMO

Introduction: Persistent infection with one of the most high-risk genotypes of human papillomavirus causes all cases of cervical cancer and a significant proportion of other genital cancers. The HPV virus, unlike any other infection that leads to cancer, is transmitted only through sexual intercourse and is less affected by the general changes and development in lifestyle and medical standards, so only vaccination and screening can prevent the HPV virus and cancers caused by it. Therefore, determining the prevalence and distribution of HPV genotypes are of utmost importance in screening strategies regarding cervical cancer and vaccination decisions against HPV that vary based on the geographical and cultural characteristics of the study area. As a result, this study aimed to determine the frequency of human papillomavirus and the distribution of this virus's genotypes in the general population of women living in 11 provinces of Iran. Materials and Methods: This study is a community-based survey study. Sampling was done by the cluster sampling method. Women aged 15-59 years old from the general population living in 11 provinces of Iran were included in the study after considering the inclusion and exclusion criteria. Data were collected using a questionnaire and vaginal examination. The study was performed on 2562 vaginal specimens that were referred to the laboratory of the present study. HPV genome was detected by the nested MY-GP method and papillomavirus genotyping was performed using the PCR multiplex method to identify 19 papillomavirus genotypes. Results: The general prevalence of HPV in the 11 provinces was obtained at 2.4% (108 out of 2562 people). The highest prevalence of the virus was in the age group of 25-34 years. The prevalence of HPV was statistically significant among different provinces. Hormozgan province with 22 cases (5.9%) had the highest and Isfahan province with 6 cases (2.2%) had the lowest incidence of HPV. The prevalence of high-risk HPV and medium-risk HPV is 3%, and the prevalence of low-risk HPV was estimated to be 2.1% of the total female population. Also, the highest prevalence was related to genotype 16. Conclusion: According to the high prevalence of the HPV virus in young age groups in Iran, it is necessary to pay attention to screening programs to reduce the incidence of cervical cancer.

RESUMO

Background: Tuberculosis (TB) remains an infectious disease with a high prevalence worldwide and represents a major public health concern. It is known that TB causes a hyper-coagulable state due to its infective nature. Thus, patients are prone to higher incidence rates of venous thromboembolism (VTE) in comparison with the general population. Although there are many risk assessment models (RAMs) that estimate the risk of VTE incidence in the general population, none have been proven to show significant prognostic value in early and accurate VTE prediction among TB patients. This study aims to investigate the accuracy of general RAMs in prediction of VTE incidence in the population of TB-positive patients. Methods: The following survey is a retrospective study among patients afflicted with TB, in whom VTE had occurred either during or at the onset of admission. A total number of 865 smear-positive TB cases were recorded in hospital in a 7-year timespan, among which a total sum of 37 patients (67.6% males, age: 56.19 ± 20 years) experienced at least one episode of thromboembolic incidence. We nominated Padua and Geneva RAMs and calculated the scores with regard to their inpatient hospital records. Results: Of 865 adult hospitalized smear-positive TB patients, 37 patients happened to develop VTE in the course of infection, after excluding the unacceptable data. The incidence of VTE was calculated at 4.27%. Of all VTEs, 73% turned out to be deep venous thromboembolism (DVT), 18.9% were pulmonary thromboembolism (PTE), and 8.1% of patients developed both DVT and PTE during the course of disease. Among all cases, 32.4% revealed Geneva score equivalent or >3. It conveys the meaning that these patients were at greater risk for VTE development and were indicated to receive prophylactic medication. Similarly, Padua model was capable of predicting 29.7% cases scoring >4, which is alarming for elevated VTE probability. 21.6% of TB patients, who had developed VTE during the course of their disease eventually passed away. Conclusion: Our statistics show minimal positive predictive value for Padua and Geneva RAMs, which are seemingly in sharp contrast with the excellent validation of these models verified by numerous surveys in general population. This fact could be attributable to failing to consider TB, or in general chronic infections, as independent indicators of VTE incidence. These findings indicate the need for revising the presenting RAMs or establishing a separate RAM for VTE prediction in TB patients, resembling the VTE risk assessment model for cancer patients.

RESUMO

BACKGROUND: Sarcoidosis is a multifactorial immune disorder with an uncertain origin. A single nucleotide polymorphism (G→A, rs2076530) in the butyrophilin-like 2 (BTNL2) gene results in the formation of truncating protein. This study aimed to genotype the predisposition of the BTNL2 rs2076530 polymorphism in Iranian patients with sarcoidosis using the RFLP technique. MATERIALS AND METHODS: In this study, 80 patients with sarcoidosis and 80 healthy individuals were included. The rs2076530 polymorphism of the BTNL2 gene was genotyped using the PCR-RFLP method by AvrII restriction enzyme and confirmed by DNA sequencing (Capillary electrophoresis 3130, ABI). RESULTS: There was a statistically significant difference between proportions of patients with AA (47,5%) and controls (27.5%) (OR=2.38, 95%CI:1.23-4.61, P=0.009). In addition, a significant difference was observed in the frequency of the A allele (62.5%) in sarcoidosis (OR=2.14, 95%CI:1.37-3.35, P=0.001). A Bonferroni correction with P<0.0038 indicates a statistical difference for genotype AA (P=0.009). In an effective model, binary logistic regression analysis indicates a statistical association between AA genotype and sarcoidosis (P=0.018 with 60% prediction). Based on the gene analysis study using DNA sequencing, all of the mentioned mutations were seen via RFLP. CONCLUSION: According to our findings, the BTNL2 rs2076530 A allele in the Iranian population is associated with susceptibility to sarcoidosis. This designed PCR-RFLP method for detecting SNPs is effective as DNA sequencing.

RESUMO

Background: The world is currently struggling with the COVID-19pandemic. Measures to control the COVID-19 pandemic have affected other health problems and diseases, including tuberculosis (TB) and its control. The present narrative review aimed at reviewing published literature on the impact of the COVID-19 pandemic on TB control. Materials and Methods: English language databases, including PubMed, ISI, Scopus, and Google Scholar, were searched using the keywords "Tuberculosis, COVID-19, and Coronavirus" to find relevant articles. Results: Problems and limitations in financial and human resources, as well as medical and laboratory services caused by the COVID-19 pandemic, contribute to the reduction in the number of newly diagnosed patients with TB. More effort in identifying patients with TB is of great importance, and if the global number of newly diagnosed patients with TB decreases by 25% for three consecutive months due to the COVID-19 pandemic, the TB mortality rate will increase by 13%. An increase in the TB mortality rate means the failure of TB control programs to reach the targets of the Global End TB Strategy. Conclusion: According to the latest statistics released by the Ministry of Health, the incidence of TB in Iran has not yet reached fewer than 100 cases per million population. On the other hand, being a neighbor with countries with a high risk of TB is a serious threat to Iran. Therefore, further effort to control TB during the COVID-19 pandemic is particularly important.

RESUMO

Aim: To validate a questionnaire to assess stress and burnout in healthcare workers during COVID-19 pandemic. Subjects and methods: In this study, content validity, Cronbach's alpha, and test-retest reliability method were utilized among 60 HCWs to evaluate the validity, internal consistency, and reliability of the questionnaire respectively. The final questionnaire was composed of four parts asking for the background information, questions about the stress caused by the COVID-19, the Depression, Anxiety and Stress Scale - 21 (DASS-21), and six questions from the Copenhagen Burnout Inventory (CBI). Results: The CVR of 46 questions was equal to 1, making them acceptably valid (CVR > 0.78), so that the items could be arranged into a final questionnaire. Moreover, all items could successfully attain CVI values above 0.79, confirming the content validity of the questionnaire. The Cronbach's alpha was between 0.80-0.95 for different sections of questionaire, confirming the stable reliability and high repeatability of the questionnaire. Conclusion: The results of this study showed that the DASS-21 offers adequate levels of validity and reliability for assessing the stress, anxiety, and depression among the HCWs engaged with the COVID-19 pandemic. Moreover, the six items adapted from the Copenhagen burnout inventory (CBI) were found to provide a good instrument for investigating the job burnout among the HCWs at Masih Daneshvari Hospital during the outbreak of the COVID-19 epidemic.

RESUMO

History of anatomy is as long as the history of medicine itself. Development of this basic science was not possible without the dedicative effort of those physicians and scholars who were committed to discover the mysteries of human anatomy. In this regard, Iranian scholars played an important role in the development of the anatomical sciences despite the religious limitations in their societies. Mansur ibn Ilyas Shirazi is an Iranian physician of fourteenth century who wrote the first color illustrated anatomical book, Mansur's Anatomy. A considerable portion of the book has been dedicated to the central and peripheral nervous system so that he could be considered as one of the pioneers of neuroanatomy.

RESUMO

Primary sarcomas of the lung represent less than 0.5% of all primary lung tumors and comprise a heterogeneous group of malignancies including synovial sarcoma (SS). Primary pleuropulmonary SS has non-specific presentations, such as chest pain, shortness of breath and cough, and its associated imaging features resemble those of other intrathoracic malignancies. The diagnosis of these tumors needs to be confirmed by cytogenetic and molecular studies. Here, we describe two rare cases of primary pleuropulmonary SS who were admitted to our hospital. We also provide a concise review of clinical, radiological, and histopathological characteristics of pleuropulmonary SS after exploring 168 studies (415 corresponding patients) that were identified through a literature search.

RESUMO

Considering the increasing prevalence and burden of coronavirus disease 2019 (COVID-19) disease and false-negative results in routine reverse transcription-polymerase chain reaction (RT-PCR) tests, additional diagnostic methods are needed to diagnose active cases of this disease. This prospective study was conducted on patients, in whom clinical and radiological symptoms/signs were in favor of COVID-19 while their first PCR test was negative. Later on, a second RT-PCR was performed and serological evaluation was carried out and results were compared with each other. Out of 707 patients who had been referred to the hospital and were clinically and radiologically suspicious of disease, 137 patients with negative RT-PCR tests entered the study. RT-PCR assay became positive for the second time in 45 (32.8%). Anti-COVID-19 IgM and IgG antibodies were positive in 83 (60.6%) and 86 (62.8%) patients, respectively. Finally, it was determined that serological test was diagnostic in 73% of patients and the diagnostic yield of serology was significantly higher after the first week of illness (54.8% in the first week and 88% after that). Taking advantage of both serological tests and RT-PCR helps in diagnosing 83.9% of cases. Based on the present study, the serology may be useful as a complementary test and in parallel to RT-PCR assay for diagnosis of COVID-19 among admitted symptomatic cases.

RESUMO

Cystic echinococcosis (CE) or hydatid disease is a zoonosis caused by ingestion of the eggs of the tapeworm Echinococcus granulosus. Larger cysts can cause symptoms by compressing surrounding tissues. Large cysts can also rupture and cause sudden onset of cough, fever, hypersensitivity reactions, and massive hemoptysis. We report a case of hydatid cyst, which caused massive hemoptysis after an urgent percutaneous coronary intervention and was successfully controlled with bronchial artery embolization. .

RESUMO

BACKGROUND: Accelerated aging and telomere shortening have been studied in many chronic diseases such as interstitial pulmonary fibrosis and chronic obstructive pulmonary disease. Different studies have shown that patients with these diseases have shorter telomere lengths than controls; this can be a marker of the progression and outcome of the disease. So far, a few studies have been evaluated the telomere length in sarcoidosis. In this study we determine the telomere length in patients with sarcoidosis and compare it with control subjects. OBJECTIVE: Our aim is to compare telomere length in patients with sarcoidosis and normal population. Methods: We select 58 patients with sarcoidosis who were visited in the sarcoidosis clinic of Masih Daneshvari Hospital. 58 sex and age-matched (with±2 years) healthy control subjects were selected. Telomere length was measured by quantitative real time PCR as described by Cawthon on peripheral blood sample. The telomere repeat copy number (T) to single-gene copy number(S) ratio was calculated using the comparative Ct method. Results: The mean and standard deviation of telomere length in the patient and control group was 0.65 ± 0.05 and 0.72 ± 0.07 respectively. There was a statistically significant difference between the two groups. (P = 0.031). Conclusion: Sarcoidosis is an inflammatory disease that can involve many organs. Like other chronic diseases, aging phenomenon occurs in that; which led to decrease cellular and tissue telomere length. This article demonstrates shorter telomere length in Iranian sarcoidosis patients compared to normal population.

RESUMO

BACKGROUND: The study aimed to evaluate the effectiveness and safety of BAE in TB patient with massive hemoptysis and evaluate the recurrence rate of hemoptysis after BAE. MATERIALS AND METHODS: In this prospective study, 68 patients with moderate and severe hemoptysis due to active or old tuberculosis who underwent bronchial arteriography were included. CXR and CT scan were performed in all patients. Selective and nonselective bronchial artery angiography was performed in all patient and 62 patients underwent embolization. RESULTS: Thirty-two patients (47.1%) had active TB and 36 patients (52.9%) had inactive TB (post-tuberculosis sequelae). Abnormality was detected in a single vessel in 30 (44.1%) patients, in two vessels in 23 (33.8%) and in more than two vessels in 13 (19.1%) patients. Embolization was performed in 62 patients and overall 95 abnormal arteries were embolized. Hemoptysis control rate was 82.3% at one month, 73.5% at three months, 69.1 % at 6 months, 63.2% at one year and 60.3% after two years. CONCLUSION: No major complication occurred as a result of BAE procedures. BAE is a safe and effective method for the management of hemoptysis in patient with tuberculosis. Only 20.6% of the patients need to repeat BAE during 2 years of follow up.

RESUMO

Coronaviruses (CoVs) are the largest group of positive-sense RNA viruses. By increasing our understanding of the interactions between CoVs and the host innate immune system, we can evaluate the development and persistence of inflammation in the lungs and reduce the risk of CoV-induced lung inflammation with a new group of genetic variants. Here, we aim to discuss some recent changes in host cell factors that may be used by CoV to promote the proliferation cycle. We also discuss different host cell signaling pathways that can be considered in the host-pathogen interactions at the molecular level. The pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has created new challenges for the cultural, economic, and health infrastructures. Therefore, it is important that healthcare systems and physicians recognize a global integrated framework for monitoring the progression of COVID-19 to develop targeted therapies that can potentially save human lives.

RESUMO

BACKGROUND: Sleep complaints are common problems in the general population and insomnia and sleep disorders place significant economic and social burdens on the community. Postmenopausal women are 2.6 to 3.5 times more likely to develop obstructive sleep apnea (OSA) compared to non-menopausal women. In this study, we evaluated sleep disorders and mental health in postmenopausal women. MATERIALS AND METHODS: This study was a descriptive cross-sectional study and the samples were selected from postmenopausal women above 50 years who had participated in a survey entitled, "Evaluation of Sleep Disorders among Adults in Tehran" in 2017. Cluster sampling method was applied with proportional allocation. A total of 4021 samples were collected, 2075 of which belonged to women. In addition, 174 out of 2075 samples were related to postmenopausal women over the age of 50. The data were analyzed using the statistical package IBM SPSS version 22.0. P-values less than 0.05 were considered significant. RESULTS: In this study, 118 (67.8%) women had insomnia for less than three months, and 23 (13.2%) women had insomnia for more than three months. The prevalence of STOPBANG parameters in this group of postmenopausal women was 37% and significantly related to Body mass index (BMI) and neck circumference at P < 0.001 and 0.006, respectively.

The use of urgent health care and quality of life issues is essential for long-term mental and physical well-being; if there is no treatment in the menopause population, there will be serious mental and physical complications.
