The course of treatment and the number of drugs used vary depending on the severity of the disease and the parts of the body involved. The resistant tuberculosis to treatment has increased in recent years. Thus, this study was conducted to investigate the frequency distribution of response to treatment of patients with tuberculosis in Sirjan, Iran. Methods: This descriptive cross-sectional study investigated all patients with tuberculosis in Sirjan city who had referred to health centers during the years 2011-2019. The data collection tool was a pre-prepared checklist that included information on age, sex, sputum smear results, sputum culture results, diabetes, patients' nationality, drug side effects, and response to treatment. Finally, data was entered into SPSS version 22, and analyzed. Results: In this study, the overall response rate was 83% and the mortality rate was 10%. Between the frequency distribution of response to treatment in terms of gender, age, sputum smear results, sputum culture results, patients' nationality and diabetes was not statistically significant difference. Also, no statistically significant difference was found between the frequency distribution of pulmonary TB treatment response in terms of drug allergy, drug hepatitis and other drug side effects. Conclusion: According to results, can be concluded that none of the variables: age, sex, smear and culture result, and history of diabetes have no an effect on response to treatment and mortality of tuberculosis. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200004&lng=pt&nrm=iso&tlng=pt Abstract Introduction: In mechanically ventilated patients, ventilator-associated pneumonia (VAP) is a major cause of prolonged hospitalization with increased morbidity and mortality. There is a lack of studies on the relationship between bacterial colonization of the ventilator circuit (VC) and VAP. This study aimed to investigate the role of bacterial colonization of VC in the development of VAP and identify antibiotic susceptibility trends for isolated strains. Methods: A prospective study of the bacterial culture has been performed between February 2021 to March 2021 on a total of 100 mechanically ventilated patients, (n =50) samples have been obtained from patient's lower respiratory tract (LRT) and (n =50) were taken from mechanical ventilator equipment VC. Paired samples of bacteria isolated from VC and LRT, where VC was colonized before LRT. Results: A total of 58 samples were cultured positively, while 42 specimens showed negative bacterial growth. However, there was no substantial difference in comparing between the bacterial colonization of the ventilator system and the patient samples. Most isolated organisms were gram-negative bacteria which were found in the ventilator circuit with 26 (68.4%), and 14 (70%) in patient's LRT. Gram-positive was detected in 12 (31.6%) and 6 (30%) of the ventilator circuit, and patient's LRT, respectively. The predominant bacterial type was Acinetobacter baumannii organism at the VC with 10 (26.3%) and LRT at 4 (20%) followed by Klebsiella pneumoniae (8 (21.1%) in VC and 4 (20%) in LRT). Moreover, A. baumannii showed a full resistance to amoxicillin and the first generation of cephalosporins, while the other bacterial types were resistant to the most antibiotics used in this research. Conclusions: Bacterial colonization of ventilator circuit VC is a significant cause of VAP development in mechanically ventilated patients. Preventive strategies for the early detection and decontamination of contaminated VC can play a crucial role in ventilator-associated pneumonia prevention. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200005&lng=pt&nrm=iso&tlng=pt Abstract Introduction: Diabetes mellitus is a chronic metabolic disorder that induces elevated plasma glucose levels. Diabetic patients are more susceptible to infections, especially fungal infections. There is a direct relationship between increased blood glucose levels and the number of Candida hyphae in the oral mucosa. This study aimed to evaluate oral candidiasis and the different Candida species found in patients with and without diabetes mellitus. Methods: A search for studies on oral candidiasis and diabetes mellitus was carried out in the following databases: PubMed (MEDLINE, Cochrane Library), Web of Science (WoS) and Google Scholar. For dichotomous outcomes, the estimates of effects of an intervention were expressed as odds ratios (OR) using the Mantel-Haenszel (M-H) method with 95% confidence intervals. Results: 25 studies were included in this meta-analysis. Diabetes Mellitus patients tripled the probability of being infected by Candida species (OR:3.16, p<0.001). Likewise, Candida species infections were more likely in patients with poor glycemic control (OR:2.94, p<0.001) and with dentures (OR:2.22, p<0.001). In contrast, neither gender nor diabetes mellitus type of diabetes conditioned fungal infections (p>0.05). The most prevalent Candida species in both diabetics and controls were C. albicans and C. tropicalis. Diabetics had significantly fewer C. non-albicans species oral infections than non-diabetics (p=0.04). Conclusions: Diabetics are more prone to oral candidiasis, especially C. albicans infections. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200006&lng=pt&nrm=iso&tlng=pt Abstract The COVID-19 pandemic and the limited therapeutic arsenal available strain daily clinical practice. Guidelines have recently recommended routine anticoagulation of hospitalized COVID-19 patients. However, apart from the expert panels' experience, the provenance of this recommendation is not clear, due to the scarce published evidence. We provide a narrative review with the objective of unraveling the rationale for this practice. First, we analyze the biochemical, histopathological and clinical evidence for a pro-thrombotic profile in COVID-19 patients. Then, we present the clinical data from previous studies and discuss to what extent they aid in clinical decision-making. We conclude that, in the absence of randomized controlled trials, which are of utmost importance, prophylactic-dose anticoagulation should be offered to critically ill patients hospitalized for COVID-19 pneumonia, particularly those with high d-dimer levels, since they are the population most likely to benefit from it. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200007&lng=pt&nrm=iso&tlng=pt Abstract The relationship between the intra-abdominal pressure (IAP) and intracranial pressure (ICP) has been suspected for more than 100 years and was subsequently confirmed by numerous studies in both animals and humans which demonstrate the link and the positive correlation between IAP and ICP. There are mounting concerns that the pneumoperitoneum created during laparoscopic surgery to create space for instrument placement and to allow safe tissue dissection may result in an increase in the ICP secondary to the increase in the IAP which may result in serious consequences in patients with Ventriculoperitoneal (VP) shunts. There is uncertainty about the safety of laparoscopic surgery in VP shunt patients. The aim of this article is to review the literature to answer the question [Is laparoscopic surgery safe in VP shunt patients with and without intraoperative monitoring of ICP]? http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200008&lng=pt&nrm=iso&tlng=pt Abstract During December 2019, a rapid increase in the number of SARS-CoV-2 (COVID-19) cases was reported worldwide. We investigated several factors for rapid increase in SARS-COV-2. Genomic sequence reveals that domestic and wild animals were likely ancestors and zoonotic source for SARS-CoVs, MERS-CoVs, and SARS-CoV-2; these viruses replicated in animals and humans during past several decades, exhibiting diverse mutations and self-limiting diseases except during outbreaks. SARS-CoV-2 has been retrospectively isolated in different studies in August 2019, several months before Wuhan reported. Hence, there is a possibility that viruses went undetected and infecting sub-clinically, in past several years, and SARS-CoV-2 antigens and neutralizing antibodies may have been present in humans since years. All SARS-CoVs are basically respiratory viruses, spread by droplets, hence droplet precautions are essential. Furthermore, silent phase of transmission (asymptomatic/subclinical) can be beneficial for humans. Lack of symptoms eventually lessen virus transmission and reduce the pathogen's long-term survival and provide strong humoral herd immunity (with sropositivity and diverse antibodies) up to several years and during epidemics. RT-PCR has low sensitivity and specificity, carries a high risk of handling live virus antigens, and requires difficult protocols. As viral load also sharply declines after few days of onset of infection, this technique might overlook infection. Furthermore, SARS-CoV-2 infection may be present in blood when oropharyngeal swabs are negative by RT-PCR. Conversely, antibodies against SARS-CoVs develop robustly in by reduced amount of antigens and ELISA for diagnosing antibodies demonstrates 100% specificity and 100% sensitivity, even in clinically asymptomatic individuals. These antibodies can be used for serologic surveys, monitoring and screening. Furthermore, screening tests for SARS-COV-2 should be avoided in unhygienic public places by nasopharyngeal swabs, which carry a high risk of further transmission, co-infection or super-infection. If above mentioned factors and Infection control policy is followed, SARS-CoV-2 pandemic can be controlled effectively. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200009&lng=pt&nrm=iso&tlng=pt Abstract Change is a learning process modeling the attitudes and values of the involved staff to adapt and show the change in daily work life. Leading the change in medical schools or in the health care system is considered one of the assignments of successful leadership that can achieve an effective organizational change under complex conditions. This review aims to show an implementation view about how to manage the change in medical institutions and how to overcome obstacles, and how to face the challenges. The resistance to change represents a major obstacle to the change process in any medical school or health care system. Thus, it should address this resistance by creating a suitable climate for carrying out the change based on a flexible strategy that may be translated into practical steps during the implementation. Moreover, the change should be institutionalized wherein new behaviors are persisting and generalizing in the medical school or the health care system as a result of the change application. In addition, the successful management of change in any medical school or system requires a well-functioning and efficient management system for achieving the intended results. Therefore, many benefits may be gained as a result of the success of a change process in any organization wherein it improves the effectiveness and efficiency of organizational and staff performance besides creating an opportunity for getting the best practices. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200010&lng=pt&nrm=iso&tlng=pt Abstract Introduction: Oral and dental (OD) disorders in children with Rubinstein-Taybi syndrome (RTS) are frequent but not well-known by dentists and pediatricians due to the syndrome being extremely rare. Objective: To describe the OD findings observed in a 5-year-old girl with RTS and to update the literature. Clinical case: The patient presented the following OD manifestations: prominent lower lip, narrow mouth opening, narrow and arched palate, history of angular cheilitis, micrognathia, poor lingual motility, plaque and tartar, bleeding from gingival areas due to poor dental prophylaxis, and malocclusion in the form of an anterior open bite. These OD manifestations are seen in more than 40-60% of patients with RTS. Conclusions: Professionals who treat children with RTS should become aware of the advisability of referring them to the pediatric dentist from 1 year of age and performing check-ups every 6 months. Dental management is often difficult so collaboration with anesthesiologists is recommended in order to carry out a safe and effective treatment. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200011&lng=pt&nrm=iso&tlng=pt Abstract Retinitis pigmentosa (RP) or hereditary retinal dystrophy is a rare disease that can be isolated (non-syndromic RP) or associated with other systemic signs (syndromic RP). Kidney damage is exceptionally reported in patients with RP, particularly in syndromic forms. Association with renal amyloidosis remains unusual with only one reported case of RP and hereditary gelsolin amyloidosis due to a G654A gelsolin mutation defining the new syndrome of Ardalan-Shoja-Kiuru. Apart from this publication, no case associating RP and AL amyloidosis has been found. We report an original case of renal damage revealing kappa-type systemic light chains amyloidosis (AL amyloidosis) in 35-year-old man with sporadic RP. Our observation is, to our knowledge, the first to report this association. http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S2695-50752021000200012&lng=pt&nrm=iso&tlng=pt Abstract Retinitis pigmentosa (RP) or hereditary retinal dystrophy is a rare disease that can be isolated (non-syndromic RP) or associated with other systemic signs (syndromic RP).
