Normal Saline Versus Low Chloride Solutions in Treatment of Diabetic Ketoacidosis: A Systematic Review of Clinical Trials.

Traditionally, normal saline solution (NSS) has been the fluid of choice in diabetic ketoacidosis (DKA) patients, but the NSS is an acidic fluid and may lead to the delayed resolution of DKA. A systemic review search was conducted on PubMed, Embase, and Central Cochrane Registry to compare the efficacy of low chloride solutions with normal saline solution in DKA resolution. Randomized clinical trials with normal saline as a control arm and low chloride solutions as an intervention arm were included. Four studies were included in the analysis. The investigated outcomes, including time to resolution for DKA and duration of insulin infusion, varied depending on the endpoint were reported in the studies. Overall, balanced solutions were generally associated with faster correction of pH. The time to reach overall DKA endpoints was comparable in both groups. We concluded that crystalloid solutions may be used as an initial resuscitation fluid in the DKA population and may lead to earlier resolution of acidosis. More clinical trial data is required to reach statistical significance for the hypothesis.

An Unfortunate Case of Takotsubo Cardiomyopathy During Plasmapheresis for Myasthenia Crisis.

A literature review shows scarce reports of myasthenic crises (MC) complicated by Takotsubo cardiomyopathy (TC). This patient cohort (0.11%) has higher all-cause mortality and prolonged in-hospital course. We present a rare case of a 72-year-old man who developed cardiogenic shock post-plasmapheresis for myasthenia crisis. He became hemodynamically unstable and developed acute respiratory failure requiring intubation 30 minutes after completion of plasma exchange. Serum troponin peaked at 3.19 ng/mL while an emergent 12-lead electrocardiogram (EKG) showed new-onset diffuse ST-segment elevation. Hypokinesis of the entire apex, anterior septum, mid-and apical inferior septum, and mid-and apical inferior wall consistent with Takotsubo cardiomyopathy was seen on bedside echocardiogram. The patient received a continuous infusion of norepinephrine and vasopressin. The hospital course was complicated by multiorgan failure and eventual demise. This case highlights MC and the potential of plasma exchange therapy to induce TC.

Can Clinicians Start Prescribing Inclisiran for Hypercholesterolemia Today? A Review of Clinical Studies for Internal Medicine Physicians and Endocrinologists.

The safety profile and efficacy margin of inclisiran as a lipid-lowering drug have been assessed in clinical trials and are underway in subgroups with relevant co-morbidities. This systematic review looks at the clinical trials that have been conducted to comment on its safety and efficacy. The conclusions can serve as a guide for practicing physicians and researchers for following current and future cohorts of patients. PubMed, Cochrane, Embase, Scopus, CINAHL, Web of Science, and Clinicaltrials.gov were searched comprehensively using the terms "Inclisiran", "ALN-PCSsc", and "ALN-PCS" using the Boolean operator "OR" with data cut-off date of June 28, 2020. The outcomes of safety and efficacy were collected and charted for the systematic review. In our study, eight clinical trials were included in the final study: the ORION (1,2,7,9-11) trials and two clinical trials (phase 1 randomized clinical trials) done before ORION trials. Favourable efficacy in terms of LDL levels and PSCK9 levels was observed across all eight clinical trials. No severe adverse effects, safety concerns, or fatalities attributable directly to inclisiran were reported. Therefore, our study results suggest a positive efficacy and safety profile of inclisiran as a lipid-lowering drug in clinical trials.

Is COVID-19 an Independent Risk Factor for Heparin-Induced Thrombocytopenia?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes a viral respiratory illness initially described in Wuhan, China, and was declared a pandemic by World Health Organization (WHO) in 2020, and the disease is named coronavirus disease (COVID-19). SARS-CoV2 is known to cause fever, cough, fatigue, and acute respiratory distress syndrome. As more patients become infected, extrapulmonary manifestations came to rise and hypercoagulability is one among those. COVID-19 could predispose patients to both venous and arterial thromboembolic events which are commonly treated with unfractionated heparin or low molecular weight heparin (LMWH). The treatment of patients who develop heparin-induced thrombocytopenia (HIT) while being treated with heparin or LMWH for COVID-induced thromboembolic complications is challenging. We describe a patient admitted to the hospital with COVID-19 pneumonia, found to have a cerebrovascular event treated with unfractionated heparin. She also received therapeutic LMWH for anticoagulation on day 1 of presentation due to atrial fibrillation. She was diagnosed with HIT and was found to have a pulmonary embolism, aortic arch mural thrombus, and arterial thrombi in the lower extremities. As more recent studies showed HIT antibodies in COVID-19 patients who are naive for heparin-based products, COVID-19 may be an independent risk factor for the development of HIT. The role of COVID-19 in the development of HIT is uncertain. High vigilance is required to diagnose and initiate treatment for HIT early in the disease course as it can be life-threatening.

Acute Appendicitis Review: Background, Epidemiology, Diagnosis, and Treatment.

Appendicitis is a common occurrence in both the adult and pediatric populations. The condition most commonly occurs between the ages of 10 and 20 years with a lifetime risk of 8.6% and 6.7% for males and females respectively. Its diagnosis focuses on clinical presentation and imaging modalities classified according to scoring systems such as the Alvarado scoring system. A number of imaging modalities can be used, with CT being the most common one. For acute appendicitis, surgical intervention is considered to be the gold standard of treatment. However, recent research has focused on other modalities of treatment including antibiotics and endoscopic retrograde appendicitis therapy (ERAT) to avoid surgical complications.

A Case of Plasmodium falciparum Malaria with a Prolonged Incubation Period of Four Years.

With increased global travel, unique diseases from different parts of the world pose a new category of differential diagnosis, and an incubation period of different infectious diseases helps narrow differential diagnosis to point to one specific etiology. The normal incubation period of Plasmodium falciparum malariais 7-40 days. We report a case of symptomatic P. falciparum malaria that manifested four years after a visit to a malaria-endemic area in a 51-year-old female patient. Our case illustrates the importance of a broad differential with regard to infectious disease including remote travel history and raises questions of the survival of P. falciparum for four years despite the administration of traditional chemoprophylactic agents.

Rhabdomyolysis in a Young Patient due to Hypothyroidism without Any Precipitating Factor.

Hypothyroidism is characterized by decreased hormone production, which results in various clinical manifestations in different organ systems. Muscular symptoms are common in patents with clinical hypothyroidism which includes muscle cramps, myalgia, and mild to moderate elevation of creatinine kinase less than five times the upper limit of normal. However, rhabdomyolysis due to hypothyroidism is rare and in most of the reported cases a precipitating factor has been found. We report a unique case of a 35-year-old male with no past medical history who presented with rhabdomyolysis due to newly diagnosed hypothyroidism without any precipitating factors and was treated successfully with intravenous fluids and levothyroxine.

Adult Onset Morgagni Hernia: Medical vs. Surgical Management.

Morgagni hernia is a type of diaphragmatic hernia where bowel content herniates through an irregular opening into the thoracic cavity. Herein, we present the case of an 84-year-old female patient with multiple hospital admissions for abdominal symptoms. Radiological studies confirmed Morgagni hernia. She underwent a laparoscopic intervention with mesh placement. She was discharged in stable condition and was doing well on follow-up.

Diagnosis of Primary Colorectal Carcinoma with Primary Breast Cancer: Associations or Connections?

Introduction Although once very uncommon, multiple primary malignant neoplasms (MPMN) are becoming an increasingly popular subject in medical literature. With 182,000 new diagnoses per annum, breast cancer is the most frequently diagnosed cancer amongst women in the United States. Colorectal cancer remains the second most commonly diagnosed cancer in females, and the third in males worldwide. Methods In order to gather literature on synchronous and metachronous occurring breast and colon cancer, we searched PubMed using keywords such as 'colorectal cancer', 'breast cancer', and 'MPMN'. We searched through case reports, case series, clinical trials, letters to the editor, and retrospective series. We included any manuscript in English published between January 1990 and January 2019. The articles featured patients who had primary colorectal cancer with primary breast cancer. Articles featuring patients with more than two malignancies or malignancies other than colorectal and breast cancer were excluded. Furthermore, any metastatic cancers were excluded as well. This narrowed our search down from over 100 manuscripts to just four.  Results Fortunately, the prognosis was found to be no different for these patients with MPMN assuming diagnosis and treatment are performed in a timely fashion. Additionally, it appears that although a patient with one primary cancer is at a greater risk for the development of a second cancer, it is still an odd phenomenon and thus an unlikely occurrence. Conclusion Detection of one cancer increases the odds of detecting another cancer. Hence, it is important to consider the possibility of a synchronous tumor in a patient with a newly diagnosed colon tumor, as well as to not only consider disease recurrence when following up post-resection.

Perforated Jejunal Diverticulitis.

Small intestinal diverticula are very rare; their incidence ranges from 0.06 to 1.3%, with a higher prevalence after the 6th decade of life. Among these small intestinal diverticula, duodenal diverticula are more frequent, followed by diverticula of the jejunum and ileum. A jejunal diverticulum is usually asymptomatic; sometimes patients complain of vague chronic symptoms like malabsorption, pain, or nausea that easily lead to misdiagnosis. Complications are rarely reported, only in 10% of patients. We report a unique case of a 70-year-old female who presented with confusion due to sepsis from perforated jejunal diverticulitis, which was successfully managed with initial resuscitation and definitive surgery.

Nephrocutaneous Fistula due to Xanthogranulomatous Pyelonephritis.

While the development of a fistulous tract from the kidney to the proximal adjacent organs is relatively common, a tract leading to the skin is a rare occurrence. The primary cause of a fistula is prior surgical intervention or malignancy leading to abscess formation. Our case involves Xanthogranulomatous pyelonephritis (XGP) causing a longstanding lobulated abscess, ultimately leading to the formation of a fistulous tract.

Late-onset Bipolar I Disorder.

Bipolar I disorder is a chronic psychiatric illness in which patients alternate between symptoms of both mania and depression. Most cases are diagnosed when patients are 20 to 50 years old. We describe a patient presenting with symptoms of acute mania at an unusually late age for this condition. After a workup for an organic etiology, including imaging studies, this 71-year-old man was diagnosed with bipolar I disorder. Since diagnosis, his condition has been managed with risperidone.

Mesalamine Associated Bradycardia.

A 38-year-old female presented with an acute flare of ulcerative colitis. She was started on prednisone and mesalamine. Within 24 hours of initiating mesalamine, she developed sinus bradycardia. After holding mesalamine, the heart rate returned to normal within five days. Our case illustrates the third described case, to our knowledge, of severe sinus bradycardia secondary to mesalamine.

Anticholinergic Toxicity Secondary to Overuse of Topricin Cream, a Homeopathic Medication.

Adverse reactions from over-the-counter medications present a challenge to physicians. Homeopathic medicine is an alternative practice, originating in Germany and gaining popularity in the United States. It utilizes dilute preparations of substances in order to treat and cure disease. Patients may potentially suffer serious effects from the use of these products as the contents and concentrations are often unclear. Here, we describe a case of suspected atropine toxicity due to the overuse of a topical homeopathic cream, Topricin, which contains belladonna, a plant containing atropine.

Streptococcus Intermedius Brain and Diverticular Abscesses After Dental Manipulation: A Case Report.

A brain abscess is defined as a focal intracerebral infection consisting of an encapsulated collection of pus, which can be a life-threatening complication of infections, trauma, or surgery. While immunocompromised patients can have a wide array of causative organisms, bacterial species represent the most common etiology in immunocompetent individuals. The incidence of brain abscesses ranges from 0.4 to 0.9 per 100,000, with a high predisposition among immunocompromised patients and in those with disruption of the blood-brain barrier. The most common causative organisms found were Streptococcus species, particularly S. viridians and S. pneumonia, Enterococcus, and Staphylococcus species, mainly S. aurieus and S. epidermidis. Microorganism can invade the brain through different mechanisms, either directly by contiguous spread and odontogenic infections, which usually cause a single brain abscess, or indirectly through hematogenous spread which can cause multiple brain abscesses. Both surgical and conservative dental procedures contribute to hematogenous spreading of oral microorganisms. Although most of those organisms are eliminated shortly after they gain access to the bloodstream, some can persist and contribute to the pathogenesis of abscesses in the appropriate environment. Odontogenic origins are rarely implicated in the formation of brain abscesses, and oral foci comprise approximately 5% of identified cases. We report a case of brain and diverticular abscesses due to S. intermidius occurring two months after dental extraction. This case highlights the fact that even usual dental workup can result in the development of bacteremia and disseminated abscesses including but not restricted to the brain. Consequently, in addition to identifying the possible source of bacteremia with an extensive history and physical exam, the diagnosis of Streptococcus milleri organisms should prompt the physicians to screen for sites of possible metastatic infection spread.

Rhabdomyolysis in a Patient Taking Both Oxandrolone for Bodybuilding and Methamphetamine.

Nonprescription drug use is increasingly prevalent in the United States. We report a case of a 31-year-old male who presented with hallucinations and was found to have rhabdomyolysis. He was consuming oxandrolone for six weeks and ingested methamphetamine the night prior to presentation. With supportive treatment, including intravenous hydration, the patient's mental status returned to baseline and rhabdomyolysis resolved. Our case illustrates the need to understand the interaction between different illicit substances. More research needs to be done to further understand the reactions between different medications as patients consume different combinations of substances.

Recurrence of Urothelial Bladder Carcinoma in the Colon Presenting as Hematochezia.

Patients with superficial bladder cancers remain clinically indolent after treatment with even a modicum of urologic intervention. However, with more invasive disease, the majority of patients experience recurrence. The conventional route of metastasis and recurrence in primary urothelial cell carcinoma is through lymphatic system, with regional lymph nodes, lungs, liver, brain, and bone being the most common sites. Isolated intraluminal colonic recurrence in the absence of local invasion is extremely rare. We report a unique case of urothelial cell carcinoma presenting with an isolated colonic mass, which unexpectedly, on immunohistostaining, proved to be primarily of urothelial rather than colonic origin.
