Patient: Male, 46-year-old Final Diagnosis: Cholecystitis Symptoms: Chest pain Medication: — Clinical Procedure: — Specialty: General and Internal Medicine Objective: Unusual clinical course Background: Cope’s sign is the association of bradycardia with symptoms of acute cholecystitis, which can occur due to a vagal cardiobiliary reflex. The clinical and electrocardiographic changes of bradycardia or complete heart block can mimic the presentation of acute coronary syndrome. This report highlights the unique possibility that bradycardia in patients with abdominal pain and gallstones can be due to this reflex. Case Report: A 46-year-old obese man with hyperlipidemia and gallstones presented with chest pain suggestive of cardiac ischemia. The initial electrocardiography (EKG) was normal, although the patient subsequently developed bradycardia and a 2 nd -degree atrioventricular (AV) block. The results of further cardiothoracic investigations (including echocardiography and pharmacologic stress testing) were normal. An ultrasound of the abdomen revealed acute cholecystitis. After he underwent a laparoscopic cholecystectomy, the chest pain resolved completely, and the EKG reverted to its normal sinus rhythm. Conclusions: Acute cholecystitis rarely presents with cardiac chest pain and EKG changes due to triggering of the vagal cardiobiliary reflex. Given this atypical presentation, patients often undergo invasive cardiac procedures in search of a nonexistent cardiac etiology coupled with the possibility of a missed diagnosis of cholecystitis. When clinicians consider a diagnosis of acute coronary syndrome in patients with bradycardia, T-wave inversion, and ST-segment elevation (especially in the inferior leads), they should add the possibility of intra-abdominal pathologies (including cholecystitis) in the differential diagnosis.
Context:Magnesium (Mg) is an intracellular cation which takes part in various functions including smooth muscle contractility. Studies have shown that serum Mg level has no significant effect on asthma severity. There are only sparse data on the effect of serum Mg level on asthma control.Aims:The aim of this study was to evaluate the effect of serum Mg level on asthma control.Settings and Design:This hospital-based cross-sectional study was conducted at the Department of Respiratory Medicine, Kasturba Medical College, Manipal.Subjects and Methods:Our participants were adult asthma patients over 18 years of age. Asthma control was assessed using a questionnaire. Serum Mg level was estimated. The study was approved by the Institutional Ethics Committee, and informed consent was obtained from the participants.Statistical Analysis Used:Welch's ANOVA test was used to analyze the correlation between serum Mg level and level of control of asthma.Results:We screened 256 patients who met the inclusion criteria. After 96 patients were removed based on exclusion criteria, 160 patients were grouped into three based on the level of symptom control. Forty-eight patients belonged to the “well controlled” group, 59 in “partly controlled” group, and the remaining 53 in “uncontrolled” group. The mean serum Mg level (mg/dl) was 2.08 ± 0.37, 2.07 ± 0.28, and 1.83 ± 0.34 in well, partly, and uncontrolled groups, respectively. As the level of control of asthma decreased from well controlled to uncontrolled, the level of mean serum Mg also decreased.Conclusions:Serum Mg levels have a positive correlation with the level of symptom control in asthma. In uncontrolled asthma, serum Mg is significantly low. Hence, it might be useful as a biomarker in assessing control or severity of asthma.
Background and objectives: Everolimus (EVE) is a mammalian target of the rapamycin (mTOR) inhibitor that is widely used in cancer patients. Pulmonary toxicity, usually manifesting as interstitial pneumonitis, is a serious adverse effect of this drug. Radiation therapy, which is often administered in conjunction with chemotherapy for synergistic effects, also causes pulmonary fibrosis. In view of pulmonary damage development in these two forms of cancer treatment, we have examined the effect of EVE administration individually, in combination with radiation given in varying sequences, and its relation to the extent of pulmonary damage. Materials and Methods: We performed an experimental study in albino rats, which were randomized into five groups: (1) control group, (2) EVE alone, (3) EVE 22 h after radiation, (4) EVE 2 h after irradiation, and (5) only radiation. Sixteen weeks after thoracic irradiation, rat lung tissue samples were examined under light microscopy, and the extent of pulmonary damage was estimated. After this, we calculated median fibrosis scores in each group. Results: The highest fibrosis score was noted in Group 4. Among the five groups, the control group had a significantly lower median fibrosis score compared to the others. When the median fibrosis score of the group that received concurrent EVE with radiation therapy (RT) (Group 4) was compared with that of the control group, the difference was statistically significant (p = 0.0022). However, no significant differences were achieved among the study groups that received EVE only or RT only, whether concurrently or sequentially (p > 0.05). Conclusion: EVE is an effective treatment option for the management of several malignancies and is often combined with other therapies, such as radiation, for a more efficient response. However, an increased risk of pulmonary fibrosis should also be anticipated when these two modalities are combined, as they both can cause pulmonary damage, especially when administered concurrently.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
