In recent years the use of immunomodulating therapy to treat various cancers has been on the rise. Three checkpoint inhibitors have been approved by the Food and Drug Administration (ipilimumab, pembrolizumab and nivolumab). The use of these drugs comes with serious adverse events related to excessive immune activation, collectively known as immune-related adverse events (irAEs). We conducted a system-based review of 139 case reports/case series that have described these adverse events between January 2016 and April 2018, found in the PubMed database. There was a broad spectrum of presentations, doses and checkpoint inhibitors used. The most common check point inhibitor observed in our literature review was nivolumab. The most common adverse effects encountered were colitis (14/139), hepatitis (11/139), adrenocorticotropic hormone insufficiency (12/139), hypothyroidism (7/139), type 1 diabetes (22/139), acute kidney injury (16/139) and myocarditis (10/139). The treatment most commonly consisted of cessation of the immune checkpoint inhibitor, initiation of steroids and supportive therapy. This approach provided a complete resolution in a majority of cases; however, there were many that developed long-term adverse events with deaths reported in a few cases. The endocrine system was the mostly commonly affected with the development of type 1 diabetes mellitus or diabetic ketoacidosis being the most frequently reported adverse events. While immunomodulating therapy is a significant advance in the management of various malignancies, it is capable of serious adverse effects. Because the majority of the cases developed pancreatic dysfunction within five cycles of therapy, in addition to the evaluation of other systems, pancreatic function should be closely monitored to minimize adverse impact on patients.
The MDRD equations were more accurate in predicting the group mean GFR in patients with ESRD than the Cockcroft and Gault formula. However, the predicted GFR using either formula was related to the basal GFR and percentage body fat.
The utility of immunotherapy, such as pembrolizumab, is becoming essential in the treatment of certain cancers. Pembrolizumab works through binding of programmed cell death 1 receptor that blocks the binding of the programmed cell death ligand 1 and is commonly used in non-small cell lung cancer and melanoma. Pembrolizumab has been reported to be associated with multiple adverse reactions such as pneumonitis, colitis, hepatitis, hypophysitis, hyperthyroidism, hypothyroidism, nephritis, and type 1 diabetes; however, pembrolizumab causing type 1 diabetes was only reported in 0.1% of the patients in clinical trials. A review of the literature generated 1,001 unique citations of which six reported cases of autoimmune diabetes associated with pembrolizumab were selected and compared. Review of the cases showed no sexual predilection and the average age of onset was 58 years old. The majority of the patients were treated for melanoma (5/6 cases), initially presented with diabetic ketoacidosis (4/6 cases), and had at one point taken ipilimumab (4/6 cases). There was no association found between the number of treatments received and the development of diabetes. With the increasing use of pembrolizumab in cancer treatment regular blood glucose monitoring during treatment, especially in patients who had also taken ipilimumab, may prevent the onset of this life-threatening complication.
Contrast-induced acute kidney injury is a common iatrogenic complication associated with increased health resource utilization and adverse outcomes, including short- and long-term mortality and accelerated progression of preexisting renal insufficiency. The incidence of contrast-induced nephropathy (CIN) has been reported to range from 0% to 24%. This wide range reported by the studies is due to differences in definition, background risk factors, type and dose of contrast medium used, and the frequency of other coexisting potential causes of acute renal failure. CIN is usually transient, with serum creatinine levels peaking at 2-3 days after administration of contrast medium and returning to baseline within 7-10 days after administration. Multiple studies have been conducted using variety of therapeutic interventions in an attempt to prevent CIN. Of these, careful selection of patients, using newer radiocontrast agents, maintenance of hydration status, and avoiding nephrotoxic agents pre- and post-procedure are the most effective interventions to protect against CIN. This review focuses on the basic concepts of CIN and summarizes our recent understanding of its pathophysiology. In addition, this article provides practical recommendations with respect to CIN prevention and management.
Background: A patient decides to leave the hospital against medical advice. Is this an erratic eccentric behavior of the patient, or a gap in the quality of care provided by the hospital? With a significant and increasing prevalence of up to 1–2% of all hospital admissions, leaving against medical advice affects both the patient and the healthcare provider. We hereby explore this persistent problem in the healthcare system. We searched Medline and PubMed within the last 10 years, using the keywords “discharge against medical advice,” “DAMA,” “leave against medical advice,” and “AMA.” We retrospectively reviewed 49 articles in our project. Ishikawa fishbone root cause analysis (RCA) was employed to explore reasons for leaving against medical advice (AMA). This report presents the results of the RCA and highlights the consequences of discharge against medical advice (DAMA). In addition, the article explores preventive strategies, as well as interventions to ameliorate leaving AMA.
Background: Morgagni hernia is a rare form of congenital diaphragmatic hernia with a prevalence of 2-3%. It occurs due to a defect on the anterior part of the diaphragm, which allows abdominal organs to penetrate into the thoracic cavity. This condition can be detected during fetal life by routine ultrasonography or late during adult life. Late diagnosis of this condition in adults is extremely rare. According to our literature search, only a few cases of symptomatic hernia in adults have been reported so far. Surgery provides definitive treatment for patients with Morgagni hernia; it is always recommended for symptomatic and asymptomatic adult patients to avoid future complications such as volvulus, small bowel obstruction, incarceration, or strangulation. We report a case of a patient who presented with chest pain due to newly diagnosed congenital diaphragmatic hernia. Case presentation: A 29-year-old unemployed white man with no significant past medical history or family history of coronary artery disease, who was a current smoker with a 1-pack-per-day history, presented to our hospital with a 1-month history of intermittent chest pain. His chest pain was localized to the right side with a pressure-like quality, moderate intensity 4-6/10, nonradiating, and relieved by standing up and worsened by lying flat. His pain was not associated with increase or decrease in activity level. The pain had progressively worsened, which prompted the patient to come to the emergency room. The patient was admitted for further evaluation. A chest x-ray showed a suspected loop of bowel on the right side of the chest. Subsequently, the patient underwent computed tomography of the chest, which revealed a 7-cm defect in the right hemidiaphragm with a large amount of intra-abdominal fat and a loop of the proximal transverse colon within the hernial sac. The patient was evaluated by a surgeon and eventually underwent laparoscopic repair of the diaphragmatic hernia with mesh repair. In follow-up, the patient's symptoms resolved. Conclusion: Morgagni hernia is a rare form of congenital diaphragmatic hernia. It is commonly found either in the first few hours of life or in the antenatal period. It is less common in adults and is usually diagnosed accidentally in asymptomatic patients. Symptomatic adult cases are extremely rare. Respiratory symptoms are the most common presenting symptoms. The primary management for both symptomatic and incidentally discovered asymptomatic cases of Morgagni hernia is surgical correction. Various thoracic and abdominal surgical approaches have been described without a clear consensus on preference for operative repair technique.
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.
