ABSTRACT
Background and objective: This study aimed to investigate the effect of oral administration of tranexamic acid (TXA) on reducing intraoperative bleeding during spinal surgeries. Method: The study was a single-center, double-blind, randomized, placebo-controlled clinical trial. Participants were individuals over 20 years old who underwent spinal surgery. Patients received 1.5 g of TXA orally, 2 h before surgery. Intraoperative bleeding volume, blood volume in the drain after surgery, length of hospital stays after surgery, incidence of nausea or vomiting, decrease in hemoglobin (Hb) level, and postoperative coagulation test results were evaluated in each group. Results: In this study, patients were assigned to each study group based on inclusion and exclusion criteria. The mean age of patients was 69.6±6.47 years, and 65% were male. There was no significant difference in age, sex, pre and postoperative Hb levels, prothrombin time (PT), or international normalized ratio (INR) between the study groups. Intraoperative bleeding volume and blood volume in the drain after surgery were significantly lower in the TXA group. Additionally, the length of hospital stay after surgery was significantly shorter in the TXA group. The incidence of nausea or vomiting was significantly higher in the TXA group. Furthermore, postoperative partial thromboplastin time (PTT) was significantly higher in the TXA group compared to the placebo group. Conclusion: Oral administration of TXA before spinal surgery leads to a significant reduction in intraoperative and postoperative bleeding without significant adverse effects and also reduces the length of hospital stay.
ABSTRACT
Background: Coronary heart disease (CHD) is an underlying cardiac condition contributing to increased COVID-19 mortality and morbidity which can be assessed by several diagnosis methods including coronary artery calcification (CAC). The goal of this study was to find out if there were potential links between CAC, clinical findings, severity of COVID-19, and in-hospital outcomes. Methods: This retrospective study evaluated 551 suspected patients admitted to teaching hospitals of the Babol University of Medical Sciences, Babol, Iran, from March to October 2021. Data included previous diseases, comorbidities, clinical examinations, routine laboratory tests, demographic characteristics, duration of hospitalization, and number of days under ventilation were recorded in a checklist. Results: Findings of current study provide evidence of a significant relationship between coronary artery calcification (CAC) and in-hospital mortality. Additionally, we observed significant correlations between CAC and several clinical parameters including age, duration of hospitalization, pulse rate, maximum blood pressure, erythrocyte sedimentation rate (ESR), blood urea nitrogen (BUN), neutrophil count, white blood cell (WBC) count, and oxygen saturation. However, we did not observe a significant association between CAC and the severity index of COVID-19. In addition, logistic regression tests did not find a significant value of CAC to predict in-hospital mortality. Conclusion: Our findings showed a significant relationship between CAC and in-hospital mortality.
ABSTRACT
Background: Coronary artery calcification (CAC) has been established as an independent risk factor for major adverse cardiovascular events. Nevertheless, the effect of CAC on in-hospital mortality and adverse clinical outcomes in patients with COVID-19 has yet to be determined. Objective: To investigate the association between CAC score and in-hospital mortality of COVID-19 patients. Method: This retrospective cohort study was conducted across tertiary hospitals of University of Medical Sciences in Babol, a northern city in Iran, and enroled 551 confirmed COVID-19 patients with definitive clinical outcomes of death or discharge between March and October 2021. Demographic and clinical data, along with chest computed tomography (CT) findings and CAC score on admission, were systematically collected. The study utilized logistic regression analysis and Kaplan-Meier plots to explore the association between CAC score and in-hospital death and adverse clinical outcomes. Results: The mean age was 60.05±12.8. A significant difference regarding CAC score, age, history of hypertension, hyperlipidemia, cardiovascular diseases, and respiratory diseases among survivors and non-survivors was observed; however, gender was not found to be different. Furthermore, in multivariate analysis, CAC score greater than or equal to 400 [odds ratio (OR): 4.2, 95% CI: 1.70-10.33, P value: 0.002], hospitalization time (OR: 1.31, 95% CI: 1.13-1.53, P value < 0.001), length of ICU stay (OR: 2.02, 95% CI: 1.47-2.77, P value < 0.001), severe or critical COVID-19 severity in time of admission (95% CI: 1.79-18.29, P value: 0.003), and history of respiratory diseases (95% CI: 2.18-40, P value: 0.003) were found to be associated with higher odds of in-hospital mortality. Log-rank test also revealed a significant difference regarding the time of admission to death between patients with CAC score greater than or equal to 400 and those with CAC score less than 400 (P value < 0.001). Conclusion: Elevated CAC score is a crucial risk factor linked to in-hospital mortality and unfavourable clinical results in confirmed COVID-19 patients. This finding emphasizes the need for careful monitoring of individuals with high CAC scores.
ABSTRACT
INTRODUCTION: Frontal sinus mucoceles commonly manifest with orbital complications. Intracranial complications, though rare, are significant in the differential diagnosis. Tumefactive and giant mucoceles can resemble intracranial tumors. CASE PRESENTATION: We present the case of a 24-year-old male patient who initially presented to our institution after experiencing a single generalized tonic-clonic seizure. Initial imaging revealed large masses in both frontal lobes. Surgical intervention revealed mucoceles originating from the frontal and paranasal sinuses. DISCUSSION: Mucoceles are often misdiagnosed due to the wide variety of symptoms they can present. In particular, the tumefactive type of mucoceles can present brain tumors both clinically and radiologically. CONCLUSION: Mucoceles can manifest as tumefactive lesions, mimicking intracranial masses, and may present as perplexing neurological conditions.
ABSTRACT
Introduction: Patients diagnosed with Coronavirus disease 2019 exhibit varied clinical outcomes, with a reported mortality rate exceeding 30% in those requiring admission to the ICU. The objective of this study was to assess the predictive capacity of Sequential Organ Failure Assessment (SOFA) and quick Sequential Organ Failure Assessment (qSOFA) scores in determining mortality risk among severe COVID-19 patients. Method and materials: This retrospective study was performed by analyzing the data of patients with COVID-19 who were hospitalized in the ICUs. Data collection of the parameters required to calculate the SOFA and qSOFA Scores were extracted from patient's medical records. All data analysis was performed using SPSS V.25. Significance level considered as P less than 0.05. Findings: In this study, 258 patients were included. The results showed that the subjects ranged in age from 21 to 98 years with a mean and SD of 62.7±15.6. Of all patients, 127 (49.2%) were female and the rest were male. The mortality rate was 102 (39.5%). The underlying disease of diabetes mellitus with an odds ratio of 1.81 (CI=1.02-3.22) had a significant effect on mortality. In addition, a significant correlation was obtained between admission duration and SOFA score (r=0.147, P=0.018). The SOFA had a very high accuracy of 0.941 and at the cut-off point less than 5 had a sensitivity and specificity of 91.2% and 82.7%. In addition, qSOFA had high accuracy (0.914) and a sensitivity and specificity of 87.3% and 91.7% at the optimal cutting point of greater than 1. Conclusion: The findings of present study illustrated that deceased COVID-19 patients admitted to the ICU had higher scores on both SOFA and qSOFA scales than surviving patients. Also, both scales have high sensitivity and specificity for anticipating of mortality in these patients. The underlying diabetes mellitus was associated with an increase in patient mortality.
ABSTRACT
Introduction and importance: SARS-CoV-2 infection, besides respiratory symptoms, as cardinal manifestation, may present with neurological involvement. Immune-mediated polyradiculoneuropathy is one of the important neurological complications manifested by COVID-19 mainly includes Guillain-Barré syndrome (GBS), treatment-related fluctuation of GBS, and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Also, there are several reports of COVID-19 vaccine-related GBS and CIDP. According to possible severe manifestations of neuropathies like respiratory failure, considering these complications for early diagnosis and treatment is very important. Case presentation: The authors presented a 67-year-old woman with severe weakness in upper and lower extremities, the patient was diagnosed as case with CIDP initiated after COVID-19 virus infection and/or vaccination that experienced one relapse in 11 months. In both episodes, treatment with intravenous immunoglobulin started and the patient respond. Clinical discussion: To the best of our knowledge, this is one of the first reported cases with a typical chronic course of CIDP associated with COVID-19 virus infection and/or vaccination. Conclusion: Considering this complication and differentiation between GBS and CIDP, and then initiating maintenance therapy can prevent long-term disability.
ABSTRACT
Objective:To review the safety issues surrounding tyrosine kinase inhibitors (TKIs), specifically, hematological adverse effects, cardiovascular issues, renal adverse effects and nephrotoxicity, endocrine system adverse effects, concerns related to the reproductive system, dermatological and gastrointestinal adverse effects. Data Sources: A literature search was performed through Web of Science, PubMed, Google Scholar, Scopus, and the Food and Drug Administration. Data Summary: Several safety issues have been raised following the use of TKIs. Most TKIs show hematological side effects. Considering cardiovascular toxicities, as opposed to imatinib which is relatively safe, new-generation TKIs may be associated with severe cardiovascular side effects. Both acute and chronic renal failure were reported with TKIs such as gefitinib, imatinib, pazopanib, sorafenib, and sunitinib. Many endocrine adverse effects have been reported including hypercholesterolemia and hypertriglyceridemia (with lorlatinib) and thyroid dysfunction (with dasatinib). TKIs may interfere with fetus implantation, growth, and gonadal development. Females receiving TKIs and encountering unwanted pregnancy may have a normal pregnancy, miscarriage, or an abnormality in the fetus. Skin toxicity has been identified as the most debilitating adverse effect in patients receiving EGFR-TKI. Gastrointestinal side effects are common with TKIs. Diarrhea was the most frequently reported adverse effect of many TKIs. Conclusions: TKIs are increasingly taking up a critical role in the treatment of cancers due to their specific action toward malignant cells compared to conventional cytotoxic chemotherapy. Despite a dramatic improvement in the survival of patients with cancer following approval of TKIs, various early and late adverse effects were reported.
ABSTRACT
INTRODUCTION AND IMPORTANCE: Spontaneous hemothorax is a rare but life-threatening condition, which is the main cause of respiratory distress during pregnancy and after delivery without any evidence of post-traumatic injury. CASE PRESENTATION: A 34-year-old woman, pregnant at 20 weeks, presented in the emergency department complaining of dyspnea accompanied by epigastric pain, with dominance on the left side. Chest X-ray and CT-scan revealed an opacity by displacing heart to the right side. Considering, there was a probability of bleeding from venous arterial malformation. Inappropriate cervical condition two days after the patient appeared thermodynamically stable a cesarean section was performed. CLINICAL DISCUSSION: Pregnancy leads to increasing the size of AVM by rising cardiac output and hypoxia. Patients who are predisposed to PAVM and intend to be pregnant should be evaluated a priori. CONCLUSION: Although the hemothorax is a rare phenomenon during pregnancy, management of fetus following this critical condition requires multidisciplinary assessment.
ABSTRACT
Introduction: and importance: There are increasing case reports of mucormycosis in patient with coronavirus disease 2019 (Covid-19). Herein, we describe the case of mucormycosis after recovery from Covid-19. Case presentation: The patient was a 73 years old woman with a history of chronic kidney disease, diabetes mellitus, hypertension, and dyslipidemia that referred to the emergency department with clinical presentation of Covid-19. On the third day of admission, the Covid-19 PCR test was negative, but the patient presented headache and pain in her upper jaw. Physical examination showed fever, erythema, and tenderness in the right cheek. Emergency biopsy and culture from sinus by subsection to mucormycosis conducted. and the diagnosis of mucormycosis was confirmed by the positive result of biopsy and culture. Despite anti-fungal treatment with Amphotericin B, patient developed severe diarrhea and became hemodynamically unstable. In the stool analysis, Strongyloides stercoralis was reported. Unfortunately, patient was expired on day thirty-two of this admission. Clinical discussion: Mucormycosis is a dangerous infection, and its rapid diagnosis is so important. On the other hand, Covid-19 may associated with many nonspecific sign and symptoms. These finding may overlap with other infections.In patients with prolonged mucormycosis infection, the development of strongyloidiasis should not be neglected. A single dose of ivermectin as strongyloidiasis prophylaxis should be given if the duration of the illness is prolonged. Conclusion: Clinicians should consider mucormycosis and its complications after Covid-19 treatment in diabetic and immunocompromised patients.
ABSTRACT
Introduction and importance: Limited information is available regarding various effects of lifestyle changes caused by coronavirus pandemic on human life. On the other hand, if the fear of getting infected by coronavirus is accompanied by other psychological crises, it can possibly lead to psychosis in people with or without a previous history of mental illness. Case presentation: The patient is a 36-year-old man with no previous history of mental illness who divorced his wife 6 months before the onset of COVID-19 pandemic. The patient developed auditory hallucinations and paranoid thoughts after the outbreak. After diagnosis of psychosis, treatment with injectable haloperidol was started. He was then treated with risperidone for maintenance therapy. On the other hand, for depressive symptoms, the patient was treated with bupropion. One week after starting the treatment, the patient's paranoid thoughts and auditory hallucinations improved. Clinical discussion: Getting infected with coronavirus or being severely afraid of it may cause symptoms of psychosis in those with a history of previous mental disease. There is also evidence that extreme fear of infection with coronavirus can lead to psychosis if accompanied by other psychological crises. Conclusion: It is necessary to pay more attention to the diagnosis and treatment of anxiety caused by COVID-19. Failure to immediately treat the anxiety caused by the fear of infection in this pandemic or other epidemics can lead to more serious problems such as psychosis and create further risks for the individual, family and community.
ABSTRACT
INTRODUCTION AND IMPORTANCE: Diabetes mellitus and hypertension are two conditions that can coexist in obese individuals. Roux-en-Y gastric bypass (RYGB) surgery, are used to control obesity. Complications such as steatorrhea, hyperoxaluria, and decreased bone mineral density, may occur after RYGB. CASE PRESENTATION: A 58-year-old woman referred to the emergency department complaining of pain on the right side of her lower abdomen. Her past medical history was RYGB surgery, COVID-19 with 40% pulmonary involvement, and Chronic Kidney Disease (CKD). Rapid progressive glomerulonephritis (RPGN) was predicted based on extensive laboratory test results. A kidney biopsy demonstrated oxalate nephropathy. Along with the findings from the kidney biopsy, acute tubulointerstitial nephritis with tubular injury secondary oxalosis was diagnosed. CLINICAL DISCUSSION: RYGB surgery and chronic kidney disease, can increase the risk of secondary oxalosis. Recent studies introduce enteric hyperoxaluria as an important marker for diagnosing end-stage kidney disease. Renal biopsy is often prescribed for absolute recognition of oxalosis. On the other hand, our patient has a recent history of COVID-19 infection. The use of anti-Covid-19 drugs in patients with renal insufficiency should be considered with caution. CONCLUSION: It is important to monitor kidney function following RYGB surgery, particularly in patients with underlying diseases such as diabetes or hypertension.
