A rare presentation of idiopathic small bowel diaphragm disease - A case report.

INTRODUCTION: Diaphragm disease, typically associated with long-term non-steroidal anti-inflammatory drug (NSAID) use, manifests as diaphragm-like small bowel strictures, often resulting in bowel obstruction. CASE DESCRIPTION: A 75-year-old male presented with features of recurrent subacute intestinal obstruction, later diagnosed with multiple small bowel strictures via CT imaging. Surgical intervention, including resection and anastomosis, was performed to alleviate the obstruction. Histopathological examination of the resected specimen confirmed diaphragm disease, challenging its traditional association with NSAID use. DISCUSSION: Diaphragm disease, characterized by mucosal and submucosal diaphragm-like strictures, is typically attributed to NSAID usage. However, this case underscores the possibility of diaphragm disease in the absence of NSAID exposure. Pathological findings supported the presence of diaphragm-like strictures, despite the patient's denial of NSAID use. CONCLUSION: This case emphasizes the importance of considering diaphragm disease as a differential diagnosis in patients with intermittent bowel obstruction, even in the absence of NSAID history.

Association of serum beta hCG levels in women with palpable malignant breast lesions.

This study aims to determine whether serum Beta hCG can be used as a tumour marker in Breast malignancies. The objective of this study is to evaluate the serum Beta hCG in various stages of breast carcinoma and to correlate its level with disease severity and prognosis. Cross sectional analytical study of assessing serum Beta hCG in 200 patients with palpable breast malignancies at hospitals in urban Mangalore, India. In our study there was No increase in serum Beta hCG, in women with breast malignancies, but there was a pattern amongst the negative results. A Beta hCG of < 5mIU/mL is taken as negative, but in our study of 200 individuals, a mean value of 2mIU/mL was used as differentiation between low and high risk individuals. With our study we tried to correlate the value of Beta hCG with malignant breast lesions, and even though women with such lesions did not have a value of > 5mIU/mL, we found substantial evidence that women who had a value of > 2mIU/mL had a more advanced disease, be it in terms of staging, and comparing it with markers like ki67. A direct correlation between Beta hCG and severity of the disease in terms of staging was proved, hereby directly affecting the outcome of patients. Higher the level of Beta hCG, graver the prognosis. Even though Beta hCG cannot be used as tumour marker, it can be used to prognosticate the severity in women with palpable breast malignancies.

Extensive Painless Aortic Dissection in a Patient With Breast Cancer.

This case illustrates the unusual clinical presentation and natural progression of type A aortic dissection, found incidentally on echocardiogram in a patient with breast cancer. Possible association of tyrosine kinase inhibitor with aortic dissection is reviewed in the light of this case.

The Year in Cardio-oncology 2022.

Cardiovascular disease and cancer are the leading causes of death worldwide. With advent of novel and improved cancer therapies, a growing population of cancer patients with cardiac complications is seen. Taking this into consideration, the clinical studies have also shifted their focus from the study of a single disease to the interdisciplinary study of oncology and cardiology. This current review article provides a comprehensive review of all major articles and guidelines from the year 2021-2022 in the field of cardio-oncology.

Trigger related outcomes of takotsubo syndrome in a cancer population.

Background: Takotsubo syndrome (TTS) occurs more frequently in cancer patients than in the general population, but the effect of specific TTS triggers on outcomes in cancer patients is not well studied. Objectives: The study sought to determine whether triggering event (chemotherapy, immune-modulators vs. procedural or emotional stress) modifies outcomes in a cancer patient population with TTS. Methods: All cancer patients presenting with acute coronary syndrome (ACS) between December 2008 and December 2020 at our institution were enrolled in the catheterization laboratory registry. Demographic and clinical data of the identified patients with TTS were retrospective collected and further classified according to the TTS trigger. The groups were compared with regards to major adverse cardiac events, overall survival and recovery of left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) after TTS presentation. Results: Eighty one of the 373 cancer patients who presented with ACS met the Mayo criteria for TTS. The triggering event was determined to be "cancer specific triggers" (use of chemotherapy in 23, immunomodulators use in 7, and radiation in 4), and "traditional triggers" (medical triggers 22, and procedural 18 and emotional stress in 7). Of the 81 patients, 47 died, all from cancer-related causes (no cardiovascular mortality). Median survival was 11.9 months. Immunomodulator (IM) related TTS and radiation related TTS were associated with higher mortality during the follow-up. Patients with medical triggers showed the least recovery in LVEF and GLS while patients with emotional and chemotherapy triggers, showed the most improvement in LVEF and GLS, respectively. Conclusion: Cancer patients presenting with ACS picture have a high prevalence of TTS due to presence of traditional and cancer specific triggers. Survival and improvement in left ventricular systolic function seem to be related to the initial trigger for TTS.

Percutaneous coronary intervention in patients with cancer using bare metal stents compared to drug-eluting stents.

Background: Management of coronary artery disease (CAD) is unique and challenging in cancer patients. However, little is known about the outcomes of using BMS or DES in these patients. This study aimed to compare the outcomes of percutaneous coronary intervention (PCI) in cancer patients who were treated with bare metal stents (BMS) vs. drug-eluting stents (DES). Methods: We identified cancer patients who underwent PCI using BMS or DES between 2013 and 2020. Outcomes of interest were overall survival (OS) and the number of revascularizations. The Kaplan-Meier method was used to estimate the survival probability. Multivariate Cox regression models were utilized to compare OS between BMS and DES. Results: We included 346 cancer patients who underwent PCI with a median follow-up of 34.1 months (95% CI, 28.4-38.7). Among these, 42 patients were treated with BMS (12.1%) and 304 with DES (87.9%). Age and gender were similar between the BMS and DES groups (p = 0.09 and 0.93, respectively). DES use was more frequent in the white race, while black patients had more BMS (p = 0.03). The use of DES was more common in patients with NSTEMI (p = 0.03). The median survival was 46 months (95% CI, 34-66). There was no significant difference in the number of revascularizations between the BMS and DES groups (p = 0.43). There was no significant difference in OS between the BMS and DES groups in multivariate analysis (p = 0.26). In addition, independent predictors for worse survival included age > 65 years, BMI ≤ 25 g/m2, hemoglobin level ≤ 12 g/dL, and initial presentation with NSTEMI. Conclusions: In our study, several revascularizations and survival were similar between cancer patients with CAD treated with BMS and DES. This finding suggests that DES use is not associated with an increased risk for stent thrombosis, and as cancer survival improves, there may be a more significant role for DES.

Left sided Amyand hernia - A case report.

INTRODUCTION: Amyand hernia is a clinical condition wherein content of the inguinal hernial sac is formed by the vermiform appendix. CASE PRESENTATION: 1 year 3-month-old male child presented to our OPD with an irreducible left inguinal hernia for which he was taken up for an emergency herniotomy. The terminal ileum, caecum and appendix were found to be the contents of the hernial sac. DISCUSSION: As the appendix is anatomically located on the right, Amyand hernia more commonly occurs on the right, however its occurrence on the left, is a rare event and is usually associated with congenital anomalies like Intestinal malrotation, Situs inversus and mobile caecum. CONCLUSION: Amyand hernia presenting on the left is extremely rare and high index of clinical suspicion is required to manage such patients. We report one such rare case of a Left sided Amyand hernia in a young child.

Predictors of Recurrence and Survival in Cancer Patients With Pericardial Effusion Requiring Pericardiocentesis.

Aim: This study investigated the factors predicting survival and the recurrence of pericardial effusion (PE) requiring pericardiocentesis (PCC) in patients with cancer. Materials and Methods: We analyzed the data of patients who underwent PCC for large PEs from 2010 to 2020 at The University of Texas MD Anderson Cancer Center. The time to the first recurrent PE requiring PCC was the interval from the index PCC with pericardial drain placement to first recurrent PE requiring drainage (either repeated PCC or a pericardial window). Univariate and multivariate Fine-Gray models accounting for the competing risk of death were used to identify predictors of recurrent PE requiring drainage. Cox regression models were used to identify predictors of death. Results: The study cohort included 418 patients with index PCC and pericardial drain placement, of whom 65 (16%) had recurrent PEs requiring drainage. The cumulative incidences of recurrent PE requiring drainage at 12 and 60 months were 15.0% and 15.6%, respectively. Younger age, anti-inflammatory medication use, and solid tumors were associated with an increased risk of recurrence of PE requiring drainage, and that echocardiographic evidence of tamponade at presentation and receipt of immunotherapy were associated with a decreased risk of recurrence. Factors predicting poor survival included older age, malignant effusion on cytology, non-use of anti-inflammatory agents, non-lymphoma cancers and primary lung cancer. Conclusion: Among cancer patients with large PEs requiring drainage, young patients with solid tumors were more likely to experience recurrence, while elderly patients and those with lung cancer, malignant PE cytology, and non-use of anti-inflammatory agents showed worse survival.

Applications of indocyanine green in surgery: A single center case series.

Background: Fluorescence imaging using indocyanine green (ICG) has revolutionized commonly performed general surgical procedures by providing superior anatomic imaging and enhancing safety for patients. ICG, when injected, shows a bright green fluorescence when subjected to the near infra-red (NIR) spectrum. Materials and methods: We employed the use of ICG in Laparoscopic cholecystectomy, Intestinal Colorectal Anastomosis and Hernia to assess vascularity of resected ends and bowel viability, Sentinel Lymph node mapping, Vascular surgery to assess amputation stump success and in assessing Flap Vascularity and healing. Results: ICG when administered had successfully shown bright green fluorescence in different cases thereby aiding in surgical procedures. Conclusion: Routine intraoperative use of ICG could pave the way for a more objective assessment of different surgical circumstances and thereby reduce personalized barriers to aciurgy. ICG fluorescence therefore seems to be a promising apparatus in standard general surgical procedures minimizing untoward errors and improving patient conformance.

Rare cause of thyroid enlargement: Localized AA amyloid goiter - A case report.

INTRODUCTION: Amyloidosis is extracellular deposition of fibrillary amyloid proteins in various organs. Amyloid infiltration in thyroid is common; however, the occurrence of clinically enlarged thyroid, subsequently leading to goiter, is a rare phenomenon. CASE PRESENTATION: 36 years old female presented to our OPD with multinodular goiter. She subsequently underwent total thyroidectomy. Thyroidectomy specimen revealed amyloid deposition with characteristic congophilia and birefringence. Further evaluation revealed it to be AA amyloidosis. There were no features of systemic amyloidosis. DISCUSSION: Amyloidosis is classified on the type of amyloid protein. Treatment of individual types of amyloidosis is diverse, and hence identification of the protein subtype is paramount. CONCLUSION: AA amyloidosis localized primarily to thyroid is infrequent, as it usually occurs with chronic inflammatory conditions or infections. Currently, there are no guidelines for the treatment of localized AA amyloid goiter. We have evidence demonstrating the successful treatment of such a condition with no recurrence noted.

Double Delayed Enhancement: Concomitant Cardiac Amyloidosis and Acute Coronary Embolism.

Hereditary cardiac amyloidosis (CA) is a relatively rare cause of nonischemic cardiomyopathy. The risk of intracardiac thrombi increases significantly in patients with CA. We report a case of a patient presenting with chest pain and acute myocardial infarction who was subsequently diagnosed with concomitant CA and acute coronary embolism.

Ethical Dilemma: Should Continuous Intravenous Drug Use Affect Appropriate Management in Prosthetic Valve Endocarditis?

Drug use is a major challenge that negatively impacts many aspects of health. The issue of drug use is growing with every passing day. Efforts to mitigate its use are countered by even more people succumbing to the intravenous drug use due to their relatively easy availability and patients' poor insight into their medical condition. Infective endocarditis (IE) is a condition with high mortality and morbidity. It requires prolonged treatment with antibiotics, and, under some special circumstances, surgical management is also necessitated. Intravenous drug users who get valve replacement after index IE episode may continue to use drugs despite our utmost efforts to prevent it. They can subsequently develop prosthetic valve endocarditis (PVE), which is one of the indications for surgical valve replacement, hence requiring a redo surgery. However, their irregular behavior can create reservations while considering a repeat valvular surgery and delay the appropriate treatment. This can increase morbidity and mortality from PVE in intravenous drug users with otherwise no or few comorbidities.

Axillary Approach for Venoarterial Extracorporeal Membrane Oxygenation Cannulation.

Extracorporeal membrane oxygenation support (ECMO) is a form of mechanical circulatory support that is used in patients with severe dysfunction of heart or lung or both. Depending on whether it is venovenous or venoarterial support, it can temporarily substitute for circulation and ventilation while the underlying cause is addressed. Traditional approach for cannulation usually involves the femoral vessels. This is due to the easy accessibility, larger lumen of vessels, and physician expertise and training in femoral approach. However, in certain circumstances like critical lower extremity ischemia, crush injury or trauma to lower extremity, and lower extremity infections (like necrotizing fasciitis), this approach is not practical. In these situations, axillary vasculature provides a good substitute for ECMO cannulation.

Cardiovascular Risk Profile of Chimeric Antigen Receptor T-cell Therapy.

Chimeric antigen receptor (CAR) T-cell therapy is a novel form of immunotherapy that has been recently introduced in clinical practice for the treatment of leukemias and lymphomas after being approved by United States Food and Drug Administration (USFDA). The risk profile of this treatment modality is not yet fully explored. As the survival of cancer patients is expected to rise due to new therapies being brought into practice, physicians are going to encounter side effects of these therapies. This may include both short-term and long-term effects. Having a good knowledge of these side effects can help the physicians recognize in advance the at-risk population and risk stratify them accordingly. Cardiac oncology is a growing field that involves the study of interaction between novel immunotherapies and their cardiac side effects. Knowing the cardiotoxicity profile of CAR T-cell therapy will help us choose the most appropriate patient population (those who can benefit the most without being at risk of harmful effects including cardiotoxicity) for the therapy. It will also help us recognize various cardiac complications, as they arise later during the lifetime of these cancer survivors.

Mitral Valve Replacement Under Venoarterial Extracorporeal Membrane Oxygenation Support for Severe Streptococcus Mitis Endocarditis.

Streptococcus mitis is an alpha-hemolytic species of Streptococcus and is the most prevalent organism of the oral flora. In patients with dental procedures or trauma and underlying damaged heart valves, it can cause infection of the valves (endocarditis). It has a propensity to affect the left-sided heart valves (mitral and aortic valves) in non-intravenous drug users (IVDU), whereas right-sided heart valves (tricuspid and pulmonic valves) in IVDU. We describe a case of a patient who presented with mitral valve endocarditis that was treated with antibiotics. He was lost to follow-up and then presented four years after his index presentation in cardiogenic shock from severe streptococcal mitis endocarditis causing severe mitral regurgitation. His course deteriorated to the point where the patient required a valve replacement surgery under hemodynamic support.

A Novel Case of Idiopathic Restrictive Cardiomyopathy.

Restrictive cardiomyopathy (CM) usually develops and progresses slowly, over a course of years. The rapid development of idiopathic restrictive CM immediately following a liver transplant is unusual. We describe the case of a patient who developed idiopathic restrictive CM fairly rapidly following a liver transplant. It progressed within a few months to the point where the patient required scheduled paracenteses and dialysis. The morphological definition of restrictive CM consists of bi-atrial dilation with non-dilated and non-hypertrophic ventricles. A cardiac biopsy may be needed when the underlying cause is not evident. When a cardiac biopsy is not able to identify a specific cause, then the word "idiopathic" is used to describe the CM.

The Mystery of Low Phosphate: Marijuana is the Smoking Gun.

Hypophosphatemia is a rarely reported side-effect of cannabis use. The potential mechanisms of hypophosphatemia include enteric malabsorption/loss, excessive urinary excretion, or rapid trans-cellular shifts. Severe hypophosphatemia from daily marijuana use is a rare side-effect. A trans-cellular shift is the most likely proposed mechanism. Although it tends to self-correct fairly rapidly, close observation for the dreaded consequences related to hypophosphatemia is required. Both the users and providers must be aware of this rare association of hypophosphatemia with daily marijuana use.

Triple Valve Replacement in a Patient with Severe Combined Aortic and Mitral Stenosis.

With recent advancements and evidence in favor of transcatheter approach for valve replacements including valve-in-valve procedures, it has become a favorable choice particularly in critically ill patients. Additionally, transcatheter mitral valve-in-valve replacement (TMViVR) is emerging as a less invasive substitute for patients with early dysfunctional bioprosthetic valve. We describe the clinical course of a 52-year-old male whose initial presentation to the hospital for dyspnea on exertion secondary to combined severe aortic and mitral stenosis got complicated requiring three valvular replacement procedures with favorable outcomes.
