Aspirin-Exacerbated Respiratory Disease Requiring Desensitization Prior to Planned Percutaneous Catheterization Intervention

Aspirin-exacerbated respiratory disease (AERD) consists of a triad of asthma, chronic rhinosinusitis with nasal polyposis, and a hypersensitivity reaction to aspirin consisting of nasal congestion and broncho-constriction. This disease presents a conundrum in cardiac patients undergoing percutaneous catheterization intervention (PCI) who might require stent deployment due to the need for aspirin as part of the dual antiplatelet therapy required if a stent is placed. Here, we present the case of a patient who underwent a coronary angiogram showing two-vessel disease but had to undergo aspirin desensitization first before planned PCI as he had a history of severe aspirin allergy in the past.

Septic Shock Secondary to Severe Gastroenteritis Resulting From Sapovirus Infection

Sapovirus causes acute gastroenteritis (AGE) which manifests as severe diarrhea and vomiting. It is most often seen in, but not limited to, children and toddlers but can occur in people of all ages. It is typically more prevalent in low to middle-income countries but has also been reported in progressive countries such as the United States. Due to the universal use of reverse transcriptase-polymerase chain reaction (RT-PCR) testing, the reported incidence of sapovirus has continued to grow as the culprit agent in both AGE outbreaks and isolated cases. Its symptoms resemble what is seen with rotavirus but with a milder clinical course. This discussion explores the dire implications of a relatively understated pathogen. Here, we present a rare case of a 20-year-old woman who presented with septic shock secondary to severe gastroenteritis as a result of sapovirus infection.

Incidental Finding of an Extensive Type B Aortic Dissection Extending to the Iliac Arteries

An aortic dissection is a life-threatening event that requires urgent evaluation. A dissection is defined as a tear in the innermost layer of the aortic wall forming a true and false lumen. This is normally diagnosed with a CT with contrast when clinical suspicion is present. Deciding whether urgent surgical intervention is required is key, as it may determine the survival of the patient. The treatment of type A aortic dissection involves emergent open-heart surgery. Medical treatment and clinical follow-up are recommended for uncomplicated type B dissections. In this report, we present a case of an extensive type B aortic dissection in an asymptomatic patient who required immediate surgical intervention.

Stroke-like Symptoms as Presenting Signs of Varicella Zoster Meningitis in an Immunocompetent Adult

Varicella zoster is one of the common causes of aseptic meningitis, typically seen in immunosuppressed individuals and rarely in the immunocompetent. The varicella zoster virus (VZV) infection is normally associated with a dermatomal rash in the abdomen with spread to the back. The small prevalence of VZV in immunocompetent individuals may be due to lack of recognition; thus, it is always important to keep it in mind when meningitis is in the differential. Here, we present a case of varicella zoster meningitis in an immunocompetent adult presenting with slurred speech, dizziness, and episodes of confusion.

A Broken Heart: A Case of Takotsubo Cardiomyopathy

Emotional stress-induced left ventricular dysfunction, also known as Takotsubo cardiomyopathy, is a condition that has become more prevalent since the turn of the century. Seen most commonly in postmenopausal women who experience an acute emotional stressor, its presentation resembles that of acute coronary syndrome with electrocardiogram changes, which is why most patients receive a left heart catheterization revealing clean or nonobstructive coronary arteries.

Food Bolus Masquerading as a Cardiac Mass on Echocardiogram

An echocardiogram is the most utilized imaging modality in the evaluation of patients with intracardiac masses. Of these, left atrial myxomas are the most common intracardiac tumors in which diagnostic recognition is important for appropriate management. This paper demonstrates a case study on how a proper physical exam along with proper imaging modalities may result in avoiding misdiagnosing patients with large sliding hiatal hernias who present with the complaint of chest pain.

This case reveals a food bolus within a sliding hiatal hernia masquerading as an intracardiac mass. Cardiac masses can potentially be misdiagnosed using transthoracic echocardiography (TTE). While transthoracic echocardiography is uniquely resourceful as a point-of-care modality, it can be challenging to confirm whether an identified mass is attached to the myocardium or other cardiac or intrathoracic structures. The patient exhibited symptoms compatible with a cardiac mass. Primarily, the physical examination is vital in determining whether the patient should be referred for additional diagnostic modalities to assess for a cardiac mass. Auscultation of bowel sounds on the cardiac examination is consistent with a suspected hiatal hernia. 

Torsades de Pointes With a Normal Magnesium Level in the Setting of Short Bowel Syndrome

Torsades de pointes (TdP) is a potentially fatal arrhythmia, typically presenting with a congenital or acquired etiology. Low serum magnesium level is a known cause leading to this arrhythmia. However, it has been found that even in the setting of a normal serum magnesium level and with no other foreseeable etiology, TdP may still occur, especially in those with chronic electrolyte deficiencies. TdP may be treated in a number of ways, including IV magnesium sulfate or defibrillation if the patient becomes unresponsive and hemodynamically unstable. In some cases, atrial overdrive is required with the use of isoproterenol. A final decision, however, would necessitate asking if the patient can be sent home on medical management to prevent recurrence of the arrhythmia or require placement of a permanent pacemaker. Here, we describe a patient developing recurrent TdP despite normal serum magnesium level in the setting of short bowel syndrome.

COVID-19 With an Initial Presentation of Intraperitoneal Hemorrhage Secondary to Spontaneous Splenic Rupture

The WHO declared coronavirus disease 2019 (COVID-19) a global pandemic in early 2020. As the pandemic has continued to evolve over a period of several months, many cases of unusual presentations are now emerging, which pose a greater challenge for physicians in terms of quickly identifying COVID-19 patients based on initial signs and symptoms. In this report, we present one such unusual presentation in a patient with sudden intraperitoneal hemorrhage and spontaneous splenic rupture with COVID-19 as the likely etiology and contributing factor. The patient was a 75-year-old Caucasian woman who presented to the emergency department (ED) with complaints of severe left-sided abdominal pain for several days without any preceding trauma. A CT of the abdomen/pelvis revealed a large amount of fluid in the abdomen, which raised suspicion of bleeding. An exploratory laparotomy revealed splenic rupture with hemoperitoneum, and the patient subsequently underwent an emergent splenectomy. The patient's COVID-19 antigen test returned positive during the surgery and was subsequently confirmed with a polymerase chain reaction (PCR) test. COVID-19 has been found to result primarily in respiratory symptoms through its ability to invade endothelial cells via angiotensin-converting enzyme 2 affinity. It is speculated that this mechanism may cause a predisposition to micro-thromboses, which can eventually lead to manifestations such as large lymphoid organ thrombosis. Based on this case presentation and the evolving literature on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), spontaneous splenic rupture is an emergent differential diagnosis that should be considered in COVID-19 patients presenting with gastrointestinal complaints such as abdominal pain and nausea.

Brugada Pattern Phenocopy Induced by Diabetic Ketoacidosis

Brugada syndrome is a congenital cardiac channelopathy characterized by ST-segment elevation (≥2 mm) and subsequent inverted T wave in a minimum of two right precordial leads (Brugada type 1 ECG [electrocardiogram] pattern) on ECG. Brugada syndrome is estimated to be responsible for 4%-12% of all sudden cardiac deaths and up to 20% in patients with structurally normal hearts. Development of a temporary Brugada pattern, known as Brugada phenocopy, has been observed in individuals presenting with reversible underlying conditions such as hyperkalemia, hyponatremia, acidosis, ischemia, and pulmonary embolism, among others. Herein we present a case of Brugada phenocopy seen in a patient in diabetic ketoacidosis, which resolved after the electrolyte abnormalities were corrected.

Extreme Weight Loss and Psychosis as Presenting Signs of Thyrotoxicosis

Thyroid storm is an acute, life-threatening syndrome due to an exacerbation of thyrotoxicosis, which is when you have an excess of thyroid hormone in the body. Thyroid storm can be precipitated by infections, surgery, or untreated thyrotoxicosis. Multisystem involvement is often seen. Typical symptoms include fever and tachycardia, which are rather common, as well as more severe symptoms such as atrial fibrillation, congestive heart failure, hepatic failure, delirium and coma. The Burch-Wartofsky Point Scale is often used for the clinical diagnosis of thyroid storm. Prompt diagnosis and therapy are required to prevent complications and mortality in patients with thyroid storm. Here we present a case of thyroid storm in a patient that presented with psychosis and significant weight loss.

An Atypical Presentation of Serotonin Syndrome

The purpose of this paper is to highlight an uncommon presentation of serotonin syndrome and discuss important points such as causes, the manifestation of symptoms, and available treatments. The report highlights the importance of recognizing typical signs and symptoms in order to uncover an atypical presentation of serotonin syndrome. Serotonin toxicity can become life-threatening if not identified early in its course and the offending agents discontinued. This can be achieved by educated physicians and careful prescribing of these agents.

Meloxicam-Induced Pancreatitis

There are 525 drugs that have been identified by the World Health Organization (WHO) as having the potential to cause pancreatitis. The most well-known drugs include mesalamine, azathioprine, and simvastatin, all of which have been well described in the literature. However, drug-induced pancreatitis only used to account for about 1%-2% of cases in the 1990s; this number has increased to up to 5% in some studies. By accounting for over 100,000 cases per year in the United States alone, it is important to be able to recognize these cases and act rapidly and appropriately to remove the offending agent. The vast majority of cases occur within six weeks of initiating or increasing the dosage of such medications. Here we present an interesting case of meloxicam-induced pancreatitis.

Hypertriglyceridemia-Induced Pancreatitis as a Result of Quetiapine use

Pancreatitis is caused by a number of different etiologies, most commonly caused by gallstone induced, alcohol, and familial hypertriglyceridemia. Other less common causes include trauma, medications, and autoimmune conditions. Drug-induced pancreatitis (DIP) is only responsible for less than 2% of all cases but is a very important etiology that has been observed with increasing frequency in the acute setting. Here we present a case of recurrent pancreatitis with no other risk factors except for the initiation of quetiapine approximately six months prior to the first episode. 

Gas in Your Stomach? A Curious Case of Complicated Emphysematous Gastritis With Concomitant Portal Venous Gas and Pneumoperitoneum Caused by Candida Glabrata

Emphysematous gastritis is a rare life-threatening infection caused by gas trapping within the gastric mucosal wall. It is diagnosed by radiological or operative findings most typically by CT scan of the abdomen. It is caused by gas-producing bacteria. Predisposing factors include but are not limited to alcohol intake, trauma, diabetes and surgery. Clinical presentation will typically include severe abdominal pain, abdominal distension and shock. Here we present the only reported case to our knowledge of Emphysematous gastritis with concomitant portal venous gas and pneumoperitoneum caused by Candida Glabrata.

Cannabis-induced Acute Coronary Syndrome: A Coincidence or Not?

Marijuana, derived from the Cannabis sativa plant, is the most commonly abused illicit drug in the United States. Now, more than ever, due to changing regulations, marijuana is more readily available and is known to be habitually used by millions. The neuropsychiatric effects of marijuana are well-known which include chronic fatigue syndrome and polyphagia. However, marijuana is also known to exert cardiac effects, such as tachycardia, hypotension, and hypertension. Marijuana has also been described in association with atrial fibrillation, ventricular tachycardia, and cardiac arrest. However, acute coronary syndromes, such as myocardial infarction in the setting of marijuana use, is rare. Herein, we present the case of a non-ST-elevation myocardial infarction (NSTEMI) in the setting of marijuana use in a 42-year-old African American male with no significant past medical history who presented with chest pain at rest one hour after smoking marijuana.

A Case of Pneumomediastinum and Pneumoperitoneum with Concurrent Massive Subcutaneous Emphysema due to Repositioning of a Tracheostomy Tube

Tracheostomy is a common procedure seen in critically ill patients that require long term ventilatory support. As with all airway access procedures, tracheotomy with prolonged tracheal tube placement comes with possible risks such as tracheal scarring, tracheal rupture, pneumothorax, tracheoesophageal fistula among others. Another possible complication, though rare, is escape of free air into the surrounding tissue, as well as pneumomediastinum (PM). This may occur due to various reasons, some of them being tracheal rupture, barotrauma or tracheal tube mispositioning. Pneumomediastinum may present with concurrent free air in other body cavities such as the peritoneum, thorax or subcutaneous tissue. Though often not life-threatening it may require treatment including high flow oxygen, ventilator management or occasionally, surgical intervention. Herein we describe a rare case of PM with communicating pneumoperitoneum and massive subcutaneous emphysema due to tracheal tube mispositioning along with a review of the literature.

Criticality and long-range correlations in time series in classical and quantum systems

We present arguments which indicate that a transitional state in between two different regimes implies the occurrence of 1/f time series and that this property is generic in both classical and quantum systems. Our study focuses on two particular examples: the one-dimensional module-1 logistic map and nuclear excitation spectra obtained with a schematic shell-model Hamiltonian. We suggest that a transitional point is characterized by the long-range correlations implied by 1/f time series. We apply a Fourier spectral analysis and the detrended fluctuation analysis method to study the fluctuations to each system.

Improved unfolding by detrending of statistical fluctuations in quantum spectra

A fundamental relation exists between the statistical properties of the fluctuations of the energy-level spectrum of a Hamiltonian and the chaotic properties of the physical system it describes. This relationship has been addressed previously as a signature of chaos in quantum dynamical systems. In order to properly analyze these fluctuations, however, it is necessary to separate them from the general tendency, namely, its secular part. Unfortunately this process, called unfolding, is not trivial and can lead to erroneous conclusions about the chaoticity of a system. In this paper we propose a technique to improve the unfolding procedure for the purpose of minimizing the dependence on the particular procedure. This technique is based on detrending the fluctuations of the unfolded spectra through the empirical mode decomposition method.

[The intercontinental schizophrenia outpatient health outcomes study (IC-SOHO): initial 6 month findings of the sample in Latin America]

The IC-SOHO study was designed to supply information on antipsychotic treatments in the real clinical practice by assessment of a large and diverse sample population with schizophrenia. This document describes the findings of the first 6 months of IC-SOHO in Latin America. To date, this is the largest observational study of its type in this region. In this observational and prospective study, those out-patients with schizophrenia, who require a change or initiation of antipsychotic medication are hospitalized. Effectiveness was evaluated using the Clinical Global Impression-Seriousness (CGI-S) grading scale. Tolerability was assessed by questionnaires on adverse events and weight measurements. Herein, the comparisons between olanzapine (monotherapy), risperidone (monotherapy) and conventional antipsychotics (monotherapy and combined therapy) are presented. As a whole, 7,658 patients participated in the ICSOHO; n=2,671 from 11 countries of Latin America that were included in this report. At 6 months, the proportion of patients who responded to olanzapine was significantly greater than those who responded to risperidone or conventional antipsychotics (p<0.001). Patients from the olanzapine group had greater improvements in all the symptom domains, including general, positive, negative, depressive and cognitive symptoms in comparison with risperidone (p<0.05) or conventional antipsychotics (p < 0.001). Extrapyramidal symptoms (EPS) and tardive dyskinesia (TD) decreased from baseline in the groups treated with olanzapine and risperidone, but increased in the conventional group. The adverse events related with the sexual function were more prominent in the conventional group. Weight gain was observed in each treatment group, although the patients from the olanzapine group had greater weight grain followed by those of risperidone and then by those of conventional antipsychotics. Our findings in this population of the Latin American sample emulate the results of other studies in different samples, where it was found that olanzapine was more effective and better tolerated than risperidone or conventional antipsychotics.

Response and relapse in patients with schizophrenia treated with olanzapine, risperidone, quetiapine, or haloperidol: 12-month follow-up of the Intercontinental Schizophrenia Outpatient Health Outcomes (IC-SOHO) study

OBJECTIVE

The primary aim of this study was to compare the effectiveness of 12 months' treatment with olanzapine, risperidone, quetiapine, or haloperidol in preventing relapse of schizophrenia. The study also examined other measures of clinical effectiveness and tolerability.

METHOD

Outpatients with schizophrenia (ICD-10 or DSM-IV), who initiated or changed antipsychotic treatment, entered this 3-year, naturalistic, prospective, observational study between November 2000 and December 2001. At baseline, subsets of patients were prescribed monotherapy with olanzapine (N = 3222), risperidone (N = 1116), quetiapine (N = 189), or haloperidol (N = 256). Patients remaining on monotherapy were assessed using the Clinical Global Impression-Schizophrenia scale. Relapse rate was determined from the responder subset. Treatment patterns, patient perception of treatment compliance, substance and alcohol intake patterns, and treatment tolerability were recorded. Results are based on 12-month treatment data.

RESULTS

Compared to haloperidol-treated patients, olanzapine- and risperidone-treated patients had approximately 3 to 4 times higher odds of response at 12 months (p <or= .001) and 6 times lower odds of relapse (p <or= .001 for olanzapine-treated patients). Among patients treated with atypical antipsychotics, olanzapine- and risperidone-treated patients had lower odds of relapse (although the difference was not significant at p <or= .001) and significantly higher odds of response (p <or= .001) compared to quetiapine-treated patients. The tolerability profile generally favored the atypical antipsychotics over haloperidol.

CONCLUSION

These interim results support the findings of randomized controlled trials and verify that in this naturalistic study, patients treated with olanzapine or risperidone monotherapy were less likely to experience relapse than patients who received haloperidol. The clinical effectiveness and tolerability profile varied significantly between the atypical antipsychotics.

Self-administered alcoholism screening test (SAAST): comparison of classificatory accuracy in two cultures

Results of stepwise discriminant analyses of the Self-Administered Alcoholism Screening Test (SAAST) administered to 181 alcoholics and 123 nonalcoholics in Mexico City were compared with results of a similar analysis of a sample in the United States (Rochester, MN). With sensitivities of 90% and 95%, specificities were 91.1% to 99.2% in the Mexican sample for total score and a nine-item version derived from the Mexican sample gave specificities between 95.1% and 99.2% at 90% and 95% sensitivities, as with the Rochester sample. The two items with greatest predictive power were the same in both cultures.
