Anti-inflammatory Effect of Metronidazole in Hospitalized Patients with Pneumonia due to COVID-19.

Metronidazole (MTZ) can decrease the levels of several cytokines. This research aimed at the investigation of the anti-inflammatory impact of MTZ in COVID-19. A randomized, single-blind clinical trial for comparing the anti-inflammatory effect of MTZ in two eligible groups of adult patients with lower respiratory tract involvement due to Covid-19 treated with a standard national method with or without MTZ was performed. Inflammatory markers were measured as the primary outcome in two groups. Oxygen saturation, length of hospital stays, and mortality of patients were evaluated as secondary outcomes. Among 44 patients with lower respiratory tract due to Covid-19, 20(45.5%) were randomly allocated in group A with the current standard treatment plus the MTZ tablet for 7 days orally and 24 (54.5%) in group B with the current standard treatment. The mean of ESR in group A was statistically significantly lower than that of group B on the seventh day (A: 38.25 ± 18.75 vs. B: 47.67 ± 26.41, p = 0.02). Moreover, the mean of IL6 diminished significantly in both A (p = 0.01) and B (p = 0.01) groups on the seventh day compared to the first day. The decrease of TNF was not significant in any of the groups A (p = 0.3) and B (p = 0.4) from the 7th day to the first day. No significant difference was not found between group A and group B groups on the CRP level (p = 0.1). Findings of this study showed the anti-inflammatory impact of MTZ in the patient with lower respiratory inflammation due to COVID-19.

Unusual presentation of the germinoma: A 26-year-old female.

BACKGROUND: Germinoma is a rare lesion found commonly in the pineal and suprasellar regions of the brain. Clinical presentation mainly involves the location and size of the tumor and the patient age. Endocrine abnormalities are the most common symptom. CASE PRESENTATION: The patient was a 26-year-old Iranian female who suffered from germinoma for a long time and was referred to Loghman Hakim Hospital for amenorrhea, polyuria, and polydipsia. Despite diagnostic challenges, she was finally diagnosed with suprasellar germinoma after endoscopic transsphenoidal surgery, followed by radiotherapy and medical interventions to complement the surgery. CONCLUSION: It is important to be able to diagnose the patient's problem at an early stage based on their history, hormonal profile, laboratory results and radiological view.

Tumor invasion to the spinal region after primary surgery: A case report.

BACKGROUND: It is believed that pituitary carcinoma is a rare disorder and arise from the transformation of benign invasive macroadenomas, and the process of this transformation takes place slowly. CASE PRESENTATION: A 51-year-old man presented with the clinical features of Cushing syndrome and walking impairment who was diagnosed with metastatic corticotroph pituitary carcinoma to the spine region, 6 years after the initial resection of a primary invasive pituitary adenoma. He made a visit to neurosurgery and endocrinology clinic with the chief complaint of weight gain, facial and extremities swelling, paresthesia, weakness, motion and speaking impairments, and HTN which all appeared through the last 1 year; hormonal laboratory tests showed urine free cortisol (UFC) 197.8 and 367. 30 ug/24hrs (36-137), cortisol 8 am after 1 mg overnight dexamethasone test 375 ng/mL (50-250) and ACTH 59 pg/mL. MRI study revealed a mass in the brainstem with the compression effect on spinal region, pituitary imagine does not differ from the last MRI. He underwent a neurosurgery for spinal mass resection, which was successful and the total mass was resected. After surgery, the patient's condition became better. CONCLUSION: Pituitary carcinoma is a rare entity impossible to recognize as a primary tumor because its diagnosis by definition requires the presence of metastasis. Clinical awareness of the rare possibility for aggressive adenomas will progress, to metastasize is essential to appropriately monitor patients for possible early detection and treatment of pituitary carcinoma.

Lifestyle Assessment in Young Adults with Ischemic Stroke: One Cross-Sectional Study in Iran.

BACKGROUND AND AIM: Lifestyle changes are associated with an increased incidence of stroke especially in young adults. The purpose of this study was to investigate the lifestyle of ischemic stroke cases under the age of 50 years. METHODS: This descriptive cross-sectional study was conducted on young adults with ischemic stroke who were admitted to some hospitals, Tehran, Iran between 2018 and 2019. Total lifestyle information collected in the form then was compared in males and females. RESULTS: Totally 11% ischemic stroke was under age 50 years. 60.7% of young adult patients were men. There was significant difference between body mass index (BMI) (P = 0.03), type of job (P = 0.04), physical activity (P = 0.02), fruit and vegetables consumption, and gender of patients (P = 0.02). CONCLUSION: According to the association between inappropriate lifestyle and ischemic stroke in young adults, it is recommended to set preventive medicine and health promotion units with insurance coverage in all clinics for risk assessment of stroke in healthy general population specialty young adults.

Comparison of two diagnostic protocols in the management of possible cardiac chest pain: One follow-up study in Iran.

BACKGROUND: Chest pain indicating acute coronary syndrome (ACS) accounts for approximately 5-10% of presents in the emergency departments (EDs). Rapid decision making is very important because longer hospital stay is associated with higher financial burden. The aim of this study was to compare current practice with a 2-hour accelerated diagnostic protocol (ADP) to manage chest pain in patients suspected to have ACS. METHODS: This is a longitudinal follow-up study on 900 patients with negative troponin measured on entrance to the ED and initially low-risk for myocardial infarction according to the emergency department of chest pain assessment score (EDACS) at the Loghman Hakim Hospital, Tehran, Iran in 2018. Patients were divided in two groups (based on odd or even days at admission time) at a ratio of 2:1 (i) current protocol with a second troponin measuring after 6 hours and (ii) ADP with a second troponin measured after 2 hours. Major adverse cardiac events (MACE) associated factors assessed in two groups over 30-days. RESULTS: Totally, the rate of return to EDs with the major adverse cardiac events was 4% (n=24) in the current protocol group and 1% (n=1) in the ADP group within 30 days. The odds ratio for MACE in 30 days in the current protocol was 4.3 times more than ADP group (95% CI: 1.28-14.56, OR: 4.33, p:0.02). In multivariable logistic regression analysis, this estimation for the current protocol was 4.10 times more than comparison group (95% CI: 1.23-13.81, OR: 4.10, p:0.01). CONCLUSION: A 2-hour ADP in patients at low-risk for myocardial infarction by EDACS had fewer adverse follow-up events than the current protocol.

Blood Lead Levels in Opium-Poisoned Children: One Cross-Sectional Study in Iran.

BACKGROUND: Lead poisoning is now more common due to accidental or intentional exposure to opium impregnated with lead. We aimed to determine the relationship between the blood lead levels (BLLs) and basic characteristics in opium-poisoned children. METHODS: In this cross-sectional study, 32 children younger than 13 years old who had been admitted to Loghman Hakim Poison Center, Tehran, Iran, due to opium poisoning, were evaluated for BLLs. Patients' demographics, symptoms, signs, and lab tests were evaluated as well as the BLLs. FINDINGS: The median and range of age in children with opium poisoning were 14 and 141 months with minimum and maximum age of 3 and 144 months, respectively, and 62.5% were boys. Their mean BLL was 9.78 ± 3.44 µg/dl and in 70% of opium-poisoned children, BLL was ≥ 5 µg/dl. There was a significant difference between mean BLLs in girls and boys (17.07 ± 6.57 µg/dl in girls and 6.61 ± 3.22 µg/dl in boys, P = 0.02). We found a significant correlation between BLL and hemoglobin (Hb) level. In very low Hb level (< 8 g/dl), the BLL was higher but with increasing Hb level, BLL increased as well; in Hb levels > 14 g/dl, BLL decreased again (P = 0.01). CONCLUSION: Although none of the children needed chelation therapy, strategies should be developed to prevent children from being exposed to opium and other materials impregnated with lead regarding its effects on all organs of children.

Pituitary macroadenoma resulting from primary hypothyroidism; a 16-year-old girl.

BACKGROUND: Primary hypothyroidism is a common medical condition. It can lead to pituitary adenoma which is usually asymptomatic, but it can also lead to symptomatic macroadenomas which are hard to diagnose due to different clinical presentations. CASE PRESENTATION: A 16-year-old girl presented for endocrinology consultation prior to neurosurgical operation. She had galactorrhea which was accompanied by vertigo & low grade blurred vision without a headache and was diagnosed with pituitary macroadenoma and was planned for a surgery. She had TSH level of more than 100 mU/L, free thyroxine of 1.9 pmol/L. Her thyroid peroxidase (TPO) antibody level was 13.3 IU/mL, insulin growth factor-1 392 µ/l and serum prolactin level 42 ng/ml. During physical exam and with the laboratory findings, we suspected for a primary hypothyroidism as the leading cause of pituitary macroadenoma. As the result, we cancel the surgery and start levothyroxine therapy 100µg daily for her. In the follow-up it revealed that our diagnosis was correct and she went into remission with pituitary gland shrinking and decreasing TSH and prolactin levels. CONCLUSION: It is important to understand the different presentation of primary hypothyroidism to decrease the unnecessary risk of maltreatment in patients.

Investigating related factors with mortality rate in patients with postoperative meningitis: One longitudinal follow up study in Iran.

Background: Postoperative meningitis (POM) is the most dreaded cause of morbidity and mortality in neurosurgery patients. This study aimed to identify incidence and mortality rate as well as related factors to outcome in patients with POM. Methods: This descriptive longitudinal study conducted on patients with POM in duration of 2 years. Incidence and mortality rates as well as related factors were studied. Results: The incidence and mortality rates of POM was 8.9% and 50%, respectively. There were statistically significant association between male gender, as well as having mechanical ventilation, and death outcome in univariable analysis. In addition, in multivariable logistic regression analysis, length of intensive care unit (ICU) stay of more than 7 days [Odds ratio (OR): 1.2, confidence interval of 95% (95%CI): 1.02-6.2), mechanical ventilation (OR: 1.1, 95%CI: 1.05-5.1], positive cerebrospinal fluid (CSF) culture (OR: 2.4, 95%CI: 1.9-4.08) were predicting factors to death outcome. Finally, we found an inverse relationship between survival function and length of ICU stay in patients with POM. Conclusion: According to the high rates of incidence and mortality due to POM in this study, preventive studies to decrease this dreaded cause of morbidity and mortality in neurosurgery patients should be the planned.

Is a Low Incidence Rate of Ventilation Associated Pneumonia Associated with Lower Mortality? a Descriptive Longitudinal Study in Iran.

BACKGROUND: Ventilator-Associated Pneumonia (VAP) is an important cause of morbidity and mortality in patients admitted to Intensive Care Unit (ICU). The current study conducted to estimate VAP incidence, attributable mortality and case fatality rate, cost, so related factors can affect the outcome in patients. MATERIALS AND METHODS: In this descriptive longitudinal study, demographic, clinical and para-clinical data were collected and attributable mortality and case fatality rate was estimated. Multivariable analysis was done to predict the possible risk factors on the outcome of VAP patients. Also, patients' survival curve was plotted based on their length of ICU stay. Finally, the additional cost due to VAP in ICU was estimated. RESULTS: Totally, 8% ICU admissions were affected by VAP and 4% expired during the ICU stay. Further, the attributable mortality rate of VAP was high as compared with standard mortality rate. The most case fatality rate was for Acinetobacter sp. (n=17 60.7%). In multivariable logistic regression analysis, age greater than 40 years, more than 96 hours mechanical ventilation and uncontrolled diabetes mellitus were predictor factors of higher mortality. Inverse association between survival time and ICU length of stay was reported. Finally, the additional cost of VAP was estimated of about 700 US$ per patients. CONCLUSION: According to the results, strategies to prevent mortality by reducing the duration of ventilation and ICU length of stay should be performed. Also, mandatory fees for the family and the healthcare system should be planned.

Association Between Socioeconomic Status and Participation in Colonoscopy Screening Program in First Degree Relatives of Colorectal Cancer Patients.

BACKGROUND: Approximately 15% to 25% of colorectal cancer (CRC) cases have positive family history for disease. Colonoscopy screening test is the best way for prevention and early diagnosis. Studies have found that first degree relatives (FDRs) with low socioeconomic status are less likely to participate in colonoscopy screening program. OBJECTIVES: The aim of this study is to determine the association between socioeconomic status and participation in colonoscopy screening program in FDRs. PATIENTS AND METHODS: This descriptive cross-sectional, study has been conducted on 200 FDRs who were consulted for undergoing colonoscopy screening program between 2007 and 2013 in research institute for gastroenterology and liver disease of Shahid Beheshti University of Medical Sciences, Tehran, Iran. They were interviewed via phone by a valid questionnaire about socioeconomic status. For data analysis, chi-square, exact fisher and multiple logistic regression were executed by SPSS 19. RESULTS: The results indicated 58.5% participants underwent colonoscopy screening test at least once to the time of the interview. There was not an association between participation in colonoscopy screening program and socioeconomic status to the time of the interview in binomial analysis. But statistical significance between intention to participate and educational and income level were found. We found, in logistic regression analysis, that high educational level (Diploma and University degree in this survey) was a predictor to participate in colonoscopy screening program in FDRs. CONCLUSIONS: According to this survey low socioeconomic status is an important factor to hinder participation of FDRs in colonoscopy screening program. Therefore, planned interventions for elevation knowledge and attitude in FDRs with low educational level are necessary. Also, reducing colonoscopy test costs should be a major priority for policy makers.
