Atrioventricular (AV) block in pregnancy is infrequently encountered and there is little management guidance available. We present a case of a 24-year-old G3P1011 at 24 weeks' gestation who presented to the obstetrics and gynecology clinic complaining of palpitations, fatigue, and dyspnea on exertion. Cardiology workup including an electrocardiogram (ECG) and Holter monitor detected second-degree type II (Mobitz) AV block with the longest asystole event lasting 15.8 seconds. A St. Jude's dual-chamber pacemaker (Abbott Laboratories, Abbott Park, IL) was implanted immediately. Standard radiation precautions were taken with additional shielding for the fetus. The patient experienced significant improvement in her symptoms. The patient went into labor at 37 3/7 weeks. Due to non-reassuring fetal heart tones, a cesarean section was performed, and a healthy baby girl was born. The management of heart block in pregnancy can be divided into involving those who are symptomatic and those who are asymptomatic. Symptoms of heart block can include palpitations, fatigue, dyspnea, and/or syncope; the presence of these symptoms warrants the placement of a pacemaker, preferably during pre-pregnancy or during the first two trimesters, as high-grade heart block is associated with significant mortality. Those who are in their last trimester or postpartum should consider the use of a temporary pacemaker as heart block could be due to pregnancy-related cardiovascular changes. For women with heart block, labor and delivery could result in worsening of bradycardia due to uterine contractions displacing blood into the central circulation. Most women with heart block do well in labor and delivery and having a pacemaker is not necessarily an indication for a cesarean section.This is the case of a 30-year-old pregnant female who presented to the medical emergency department with signs and symptoms consistent with a psychotic episode. At the time of presentation, the patient was noted to have paranoia and delusions focused on her current pregnancy. On further evaluation in the emergency department, the patient's urine toxicology was found to be positive for methamphetamines. Following medical clearance, the patient was admitted for acute inpatient psychiatric stabilization. During hospitalization, her psychosis rapidly resolved with only the use of two emergency treatment injections containing antipsychotic medication. This case presents an interesting differential diagnosis between a brief psychotic disorder with peripartum onset and a substance-induced psychosis, and allows for further discussion in the differentiation and clinical treatment of these diagnoses.Statins are a ubiquitous medication class in the primary care setting where they provide effective primary and secondary prevention of coronary artery disease by lowering cholesterol. selleckchem While statins are mostly safe, muscle-related adverse events are well described. Very rarely patients can actually develop elevated creatine kinase (CK) consistent with myonecrosis. We present a case of progressive anti-hydroxymethylglutaryl coenzyme A reductase (anti-HMGCR) inflammatory myopathy, which was misdiagnosed for many months. Our patient was a 67-year-old gentleman sent to the ER by the Internal Medicine Clinic for profound weakness and melena. He had recently undergone esophagogastroduodenoscopy (EGD) for evaluation of progressive dysphagia and was found to be significantly anemic. Repeat EGD demonstrated a bleeding ulcer, and his weakness was attributed to anemia; however, careful examination demonstrated objective muscle weakness which could not be attributed to anemia alone. Subsequent work-up demonstrated myositis due to HMGCR antibody. Statin cessation and treatment with steroids and intravenous immunoglobulin (IVIG) led to a nearly full recovery in strength and resolution of dysphagia over the next several months.Acute epiploic appendagitis is a benign condition caused by inflammation of the epiploic appendages that are serosal lined outpouchings of the colon lying adjacent to the tenia coli. This rare condition has non-specific clinical findings and is frequently misdiagnosed as either acute diverticulitis or acute appendicitis. However, unlike other surgical causes of acute abdomen, epiploic appendagitis is a self-limited condition and resolves with conservative management. CT of the abdomen plays a vital role in diagnosing this condition and excluding other causes of acute abdomen. This case report highlights the importance of being aware of this rare condition and its consideration in the differential diagnosis of acute lower abdominal pain to avoid unnecessary hospitalization and surgery.Sarcoidosis is a systemic granulomatous disease with a highly variable clinical impact. Accurate prognostic evaluation is fundamental to establish the best therapeutic approach. Multiorgan disease and especially the involvement of vital organs, such as the heart, are associated with worse outcomes and often require more aggressive therapy. Here, we describe the case of a young adult with sarcoidosis with lymph node, pulmonary, hepatosplenic, and cardiac involvement. This clinical scenario emphasizes the importance of a thorough prognostic assessment and highlights some of the main unmet clinical needs for the risk stratification and management of these patients.Subacute combined degeneration (SCD) is caused by demyelination of spinal cord white matter secondary to vitamin B12 (cobalamin) deficiency leading to core symptoms of spastic paresis and vibratory and proprioceptive deficits. Most common causes of B12 deficiency revolve around malabsorption and pernicious anemia; however, nitrous oxide (N2O) can also indirectly cause B12 deficiency by inactivating its biologically active form. We report a case of a patient who took advantage of the unregulated N2O market and presented with signs and symptoms of SCD secondary to N2O abuse. Prior to symptom onset, the patient reported approximately 3,000g of N2O inhalation within five days prior to symptom onset in addition to daily use three weeks prior. Work up revealed laboratory and imaging abnormalities consistent with SCD, although B12 levels were normal intrinsic-factor-blocking (IFB) antibodies were present. Appropriate treatment was undertaken, and the patient was followed up at one week and one month with noticeable clinical improvements.
