Differences in Severity and Outcomes Between Hypertriglyceridemia and Alcohol-Induced Pancreatitis

Background: Alcohol and hypertriglyceridemia (HTG) are among the most common causes of acute pancreatitis (AP) after gallstones. However, differences in severity at the time of presentation and outcomes have not been well-studied. Objective: The aim of this study is to assess the differences between severity at presentation and outcomes of AP of hypertriglyceridemic and alcoholic origins. Materials and Methods: A retrospective review of 177 patients who were discharged with diagnosis of AP was performed. Severity at presentation was identified by the presence of systemic inflammatory response syndrome, bedside index for severity in AP (BISAP) score, and Balthazar index. Outcomes were measured by the length of stay, intensive care unit care, surgical intervention, and mortality. Results: We found 147 patients with alcoholic pancreatitis and 30 patients with hypertriglyceridemic pancreatitis. A larger percentage of hypertriglyceridemic pancreatitis patients (23.33%) had a BISAP score of ≥2 compared to the alcoholic group (12.24%). Only 32.65% of the patients with alcoholic pancreatitis but 60% of the patients with hypertriglyceridemic pancreatitis had the presence of systemic inflammatory response syndrome (SIRS) at admission (P = 0.0067). There were 73.34% hypertriglyceridemic pancreatits patients and only 40.28% alcoholic pancreatitis patients with Balthazar index C or greater, suggesting a higher disease burden at admission for hypertriglyceridemic pancreatitis patients (P = 0.0047). There was a statistically significant difference in the relative number of hypertriglyceridemic and alcoholic pancreatitis patients receiving intensive care (P = 0.00030) and in receiving surgical interventions related to pancreatitis (P = 0.016). Conclusion: Our study found that patients with hypertriglyceridemic pancreatitis have a greater severity of disease and they experience less favorable outcomes than patients with alcoholic pancreatitis.

Role of cannabis in digestive disorders.

Cannabis sativa, a subspecies of the Cannabis plant, contains aromatic hydrocarbon compounds called cannabinoids. [INCREMENT]9-Tetrahydrocannabinol is the most abundant cannabinoid and is the main psychotropic constituent. Cannabinoids activate two types of G-protein-coupled cannabinoid receptors: cannabinoid type 1 receptor and cannabinoid type 2 receptor. There has been ongoing interest and development in research to explore the therapeutic potential of cannabis. [INCREMENT]9-Tetrahydrocannabinol exerts biological functions on the gastrointestinal (GI) tract. Cannabis has been used for the treatment of GI disorders such as abdominal pain and diarrhea. The endocannabinoid system (i.e. endogenous circulating cannabinoids) performs protective activities in the GI tract and presents a promising therapeutic target against various GI conditions such as inflammatory bowel disease (especially Crohn’s disease), irritable bowel syndrome, and secretion and motility-related disorders. The present review sheds light on the role of cannabis in the gut, liver, and pancreas and also on other GI symptoms, such as nausea and vomiting, cannabinoid hyperemesis syndrome, anorexia, weight loss, and chronic abdominal pain. Although the current literature supports the use of marijuana for the treatment of digestive disorders, the clinical efficacy of cannabis and its constituents for various GI disorders remains unclear.

Role of cannabis in cardiovascular disorders

The growing popularity of medical and recreational consumption of cannabis, especially among the youth, raises immediate concerns regarding its safety and long-terms effects. The cardiovascular effects of cannabis are not well known. Cannabis consumption has been shown to cause arrhythmia including ventricular tachycardia, and potentially sudden death, and to increase the risk of myocardial infarction (MI). These effects appear to be compounded by cigarette smoking and precipitated by excessive physical activity, especially during the first few hours of consumption. Cannabinoids, or the active compounds of cannabis, have been shown to have heterogeneous effects on central and peripheral circulation. Acute cannabis consumption has been shown to cause an increase in blood pressure, specifically systolic blood pressure (SBP), and orthostatic hypotension. Cannabis use has been reported to increase risk of ischemic stroke, particularly in the healthy young patients. The endocannabinoid system (ECS) is currently considered as a promising therapeutic target in the management of several disease conditions. Synthetic cannabinoids (SCs) are being increasingly investigated for their therapeutic effects; however, the value of their benefits over possible complications remains controversial. Despite the considerable research in this field, the benefits of cannabis and its synthetic derivatives remains questionable even in the face of an increasingly tolerating attitude towards recreational consumption and promotion of the therapeutic complications. More efforts are needed to increase awareness among the public, especially youth, about the cardiovascular risks associated with cannabis use and to disseminate the accumulated knowledge regarding its ill effects.

Level of red cell distribution width is affected by various factors.

To the Editor, We read with much interest the recently published article ‘Prognostic value of red blood cell distribution width in acute pancreatitis patients admitted to intensive care units: an analysis of publicly accessible clinical database MIMIC II’ in the January 2016 issue of your esteemed journal Clinical Chemistry and Laboratory Medicine [1]. In this study, the authors concluded that red cell distribution width (RDW) can be used to predict hospital mortality in acute pancreatitis (AP) patients who were admitted to an intensive care unit (ICU). However, some of their findings in this study need extra attention. MIMICII is an old database and the definition and criteria of diagnosis of acute pancreatitis has changed since then [2]. Because of these new criteria some of these patients may not qualify to be considered as AP anymore. The authors did not point out if these patients had primary or secondary diagnosis of acute pancreatitis as RDW can also be affected by other acute inflammatory conditions [3]. RDW can be affected by many conditions including liver disease, anemia, folate and vitamin B12 deficiency [4]. It is well known that alcoholism is the second most common cause of AP after gallstones. Alcohol use is related to development of macrocytosis and both of these conditions can affect RDW directly [5]. We understand that these values might not be available in the MIMIC II database but because of presence of so many aforementioned confounding factors, results of this study should be interpreted with caution.

Spontaneous Acute Tumour Lysis Syndrome in Gastric Adenocarcinoma: A Case Report and Literature Review

Acute tumour lysis syndrome (ATLS) is one of the lifethreatening complications of chemotherapy for cancers. It has typical biochemical finding of hyperuricaemia, acute renal failure, hyperkalaemia, hypophosphataemia and hypocalcaemia. These findings are caused by disintegration of tumour cells and subsequent release of their content in to the blood [1]. ATLS is usually seen in tumours with heavy cell turnover and large burden. It is because of this reason, ATLS is primarily seen in cancers of the blood but it has also been more increasingly recognized in solid tumours. Recently, ATLS has been described in relation to cancers of the colon [2], gall bladder [3], biliary tract [4], skin [5] and breast [6]. Here, we describe an exceedingly rare case of spontaneous ATLS in a patient with gastric adenocarcinoma. To our knowledge, only one case of spontaneous ATLS has been described previously in literature with adenocarcinoma of the stomach which was reported more than a decade ago [7].

Herpes zoster meningitis with multidermatomal rash in an immunocompetent patient

A case of herpetic rash in an immunocompetent patient is described, which was present in multiple dermatomes at the same time. First, patient was thought to have immunodeficiency, but further workup turned out to be negative for it. Patient also had pleocytic lymphocytosis in cerebrospinal fluid, which was suggestive of viral meningitis. Later, the patient responded well to the acyclovir therapy and was discharged home without any sequel. This case illustrates the need for emergency physicians to be extra vigilant for involvement of other dermatomes in case a patient presents with herpetic rash in 1 dermatome because patients with multidermatomal/disseminated herpetic rash need to be started on airborne isolation in addition to contact precautions to prevent the transmission of disease in health care settings.

Does obesity affect the outcomes in takotsubo cardiomyopathy? Analysis of the Nationwide Inpatient Sample database, 2010-2014

Obesity can lead to increased oxidative stress which is one of the proposed mechanisms in the etiopathogenesis of takotsubo cardiomyopathy (TCM).

superior mesenteric artery syndrome: a unique complication following carboplatin-based chemotherapy

Superior mesenteric artery syndrome (SMAS) is an uncommon condition, attributable to vascular compression of the third part of the duodenum between the superior mesenteric artery and the abdominal aorta. It can present in patients due to mechanical compression or severe weight loss. We present a unique case of SMAS in a patient undergoing carboplatin-based chemotherapy for mesothelioma. An 81-year-old male with mesothelioma was treated with carboplatin-based chemotherapy. He subsequently suffered a progressive, unintentional 18 kg weight loss and presented acutely with intense epigastric pain, severe nausea, and vomiting. Diagnosis was confirmed by abdominal computed tomography and esophagogram with upper gastrointestinal series, which revealed gastric and duodenal distention and a narrow angle between the superior mesenteric artery and aorta, causing compression of the duodenum. Prompt recognition of this syndrome allowed us to treat our patient successfully and avoid the risks of operative interventions. To our knowledge, this is the first reported case of SMAS in patients receiving carboplatin. Furthermore, this case of SMAS was unique in that it was due to weight loss as compared with mechanical obstruction. Our experience illustrates the importance of considering SMAS in chemotherapy patients, especially those with substantial weight loss. A high index of suspicion for this potential complication coupled with appropriate radiographic studies are necessary for early diagnosis and can prevent severe consequences.

Wearing the mask of ST-elevation myocardial infarction: postpericardiotomy syndrome

INTRODUCTION Postpericardiotomy syndrome (PPS) is an inflammatory process, affecting 15% to 20% of patients, after surgery involving pleura, pericardium, or both. The role of electrocardiogram (ECG) in diagnosing PPS is uncertain because ECG is rarely normal (especially after cardiac surgery). We report a case of PPS that presented initially with localized ST-segment elevation and also discuss proposed mechanisms. CLINICAL CASE A 60-year-old White man presented to the emergency department (ED) after having chest pain, shortness of breath, and palpitation for approximately 2 hours. Patient had known coronary artery disease, status postcoronary artery bypass graft a month earlier with a graft to right coronary artery, and 2 grafts to marginal arteries. In the ED, ECG revealed localized ST-segment elevations in leads II, III, and aVF. Coronary angiography did not reveal significant coronary artery stenosis, and all the grafts were found to be patent. Following ECG showed PR depression along with diffuse ST elevation consistent with pericarditis. Patient was started on nonsteroidal anti-inflammatory drugs and colchicine with significant improvement of his symptoms in a few days. DISCUSSION In our patient, injury or surgical manipulation to the area perfused by right coronary artery might have initiated a process, initially localized to the inferior wall with subsequent diffuse involvement of the entire pericardium. The presentation of our patient shortly after the development of chest pain and availability of 2 ECGs a few minutes apart may have shed light on the pathophysiology of PPS.

A Rare Cause of Acute Pancreatitis: Intramural Duodenal Hematoma

We describe an interesting case of intramural duodenal hematoma in an otherwise healthy male who presented to emergency room with gradually progressive abdominal pain, nausea, and vomiting. This condition was missed on initial evaluation and patient was discharged from emergency room with diagnosis of acute gastritis. After 3 days, patient came back to emergency room and abdominal imaging studies were conducted which showed that patient had intramural duodenal hematoma associated with gastric outlet obstruction and pancreatitis. Hematoma was the cause of acute pancreatitis as pancreatic enzymes levels were normal at the time of first presentation, but later as the hematoma grew in size, it caused compression of pancreas and subsequent elevation of pancreatic enzymes. We experienced a case of pancreatitis which was caused by intramural duodenal hematoma. This case was missed on initial evaluation. We suggest that physicians should be more vigilant about this condition.
