Acute Pancreatitis Secondary to Cocaine Intoxication: A Case Series.

Gallstones, alcohol use, hypertriglyceridemia, and hypercalcemia have been considered the most common causes of acute pancreatitis; however, about 20% of the cases remain idiopathic since no definite cause can be established. It has been noticed that there is a small number of patients who have presented to the hospital with a diagnosis of acute pancreatitis who have concurrently been using cocaine yet have no recent alcohol use and no gallstones. The purpose of this series of case reports is to review the evidence behind the association between cocaine and pancreatitis. In most of the cases, the etiology of acute pancreatitis is usually straightforward. However, when faced with a patient who has acute pancreatitis but lacks the common causes such as alcoholism, gallstones, normal triglyceride levels, and no evidence of malignancy, it seems reasonable to consider drugs as a potential cause for pancreatitis.

Atypical Manifestation of Adult Polycystic Kidney Disease in an Elderly Individual.

Autosomal dominant polycystic kidney disease (ADPKD) is a rare genetic disease. Diagnosis of ADPKD is usually made by the number of renal cysts on the ultrasound for each age category. There are two types of ADPKD, and the patients with the second type have later onset of symptoms, with slower disease progression than in the first type. These patients are typically at risk of recurrent urinary tract infections, hemorrhage and rupture of cysts, end-stage renal disease, calculi, liver/pancreatic cysts, and brain aneurysm development.

Massive Calcified Abdominal Aortic Aneurysm Presenting as Low Back Pain.

Calcified abdominal aortic aneurysm (CAAA) is a radiological finding that manifests the calcification in the bulged aortic walls. CAAA has high mortality. The presence of calcification as a key player in abdominal aortic aneurysm (AAA) rupture risk was reported in the literature. Factors contributing to a CAAA compared to AAA are age, dyslipidemia, hypertension, diabetes mellitus, genetics, disturbances in calcium-phosphate homeostasis, and smoking. There are a few genetic mutations associated with CAAA as well. Causes of AAA include lipid build-up in the aortic wall, inflammatory diseases, traumas, blood vessel diseases that supply the aortic wall, and connective tissue disorders.

Metastatic Clear Cell Renal Cell Carcinoma Presenting as Acute Appendicitis.

Renal cell carcinoma (RCC) is a malignant tumor arising from the epithelial cells of kidney tubules. It may metastasize to many sites; however, metastasis of RCC to the appendix is very rare. Renal cell carcinomas usually metastasize to the lungs, lymph nodes, bones, or liver. Metastasis usually occurs within three years after radical nephrectomy; however, there is evidence of RCC metastasis many years following nephrectomy.

A Case of Adult Epiglottitis in a Patient With Uncontrolled Diabetes and Occupational Risks.

Epiglottitis is inflammation of the epiglottis with or without the involvement of supraglottic structures including the hypopharynx. Timely diagnosis is crucial as the treatment of epiglottitis is tailored to the degree of airway obstruction. Most patients improve with conservative measures, while some require an emergent airway intervention. We report a case of a 39-year-old Caucasian male with a history of uncontrolled diabetes mellitus and smoking who presented to the emergency department (ED) with a sore throat, dry cough, odynophagia, and difficulty swallowing. He was afebrile, tachycardic, tachypneic, hypertensive, and saturating at 99% on room air. His physical examination was remarkable for drooling, muffled voice, pharyngeal swelling, and erythema. Laboratory tests were significant for leukocytosis, hyperglycemia, and hemoglobin A1c (HbA1c) of 14.3% with a negative infectious workup. Lateral neck X-ray and emergent direct fiberoptic laryngoscopy revealed findings of epiglottitis with airway patency. The patient did not require intubation and was started on intravenous dexamethasone, vancomycin, ampicillin-sulbactam, and humidified air with suctioning of secretions and quickly recovered. In addition to known risk factors for developing epiglottitis such as uncontrolled diabetes and smoking, our patient was exposed to metal shavings at his new job, an occupational hazard that might have contributed to his clinical presentation. Our case highlights the importance of a prompt diagnosis and risk factor identification in the management of epiglottitis in adults.

Grade III solitary fibrous tumor/hemangiopericytoma: An enthralling intracranial tumor-A case report and literature review.

Hemangiopericytomas account for less than 1% of all intracranial tumors. In 2016, World Health Organization (WHO) unified the two terms into a single medical condition known as solitary fibrous tumor/hemangiopericytoma (SFT/HPC). Our patient is an 80-year-old woman with a past medical history of sick sinus syndrome status post pacemaker placement. She presented to the emergency department with progressive headaches for one month duration. Her headaches worsened at night, waking her up from sleep. They also increased in intensity by bending forward. Review of systems was significant for bilateral lower extremity weakness accompanied by difficulty walking. The motor exam was remarkable for right upper and right lower extremity 3/5 weakness. The gait was ataxic. A Computed tomography scan of the head without contrast revealed a large dural-based right parietal hyperdense mass with surrounding edema, mass effect, and compression of the right lateral ventricle atrium. A right-to-left midline shift was also noted. Given the fact that our patient had a pacemaker, she was not a candidate for a brain MRI. Neurosurgery successfully resected the mass. Histopathological studies confirmed WHO grade III anaplastic solitary fibrous tumor/hemangiopericytoma. The patient was discharged on adjuvant radiation with imaging surveillance given the grade and the extent of resection. This case highlights a rare type of intracranial mass that resembles meningioma on imaging studies. It also illustrates that solitary fibrous tumor/hemangiopericytoma should be kept as a differential diagnosis for brain masses, given its aggressive nature, and its potential of metastasis and recurrence.

Common Variable Immune Deficiency: An Outpatient Experience.

OBJECTIVES: Common variable immunodeficiency (CVID) is one of the most common primary immunodeficiencies encountered by physicians, yet it is still poorly described and vastly underdiagnosed and underreported. It is characterized by low levels of immunoglobulins IgG, IgM, and IgA, recurrent infections, and an increased incidence of autoimmune conditions and malignancies. Diverse clinical presentation, poor understanding of its true prevalence, and the daunting, rarely ordered, diagnostic testing make this disease incredibly difficult to diagnose in a primary care setting. Our objectives in this study were to establish a simple marker that can be used in a primary care setting to raise suspicion of CVID and prompt further diagnostic testing and to demonstrate that the true prevalence of CVID is much higher than previously reported. METHODS: Data on 441 patients who underwent Ig electrophoresis testing during a 4-year period were analyzed retrospectively for the presence of hypogammaglobulinemia and number of clinic visits for infectious processes. RESULTS: The average number of clinic visits before testing in patients with no identified antibody deficiency was 1.89 and in patients with any deficiency 2.22. The odds ratio for each additional visit was 1.089, which was not statistically significant (P = 0.103). When the data were recoded to be capped at 6 clinic visits, the odds ratio for each visit up to 6 was 1.119, which was marginally significant (P = 0.058). CONCLUSIONS: Patients with Ig deficiencies tend to have a higher number of office visits related to infectious processes. This difference, however, was not statistically significant in our study, likely because of the small number of participants. Our study also demonstrated that the prevalence of CVID is likely much higher than currently reported, and it highlights the difficulties related to the convoluted diagnostic process of this disease.

Pyogenic Hepatic Abscess: A Case Report and Literature Review on a Rare Complication of Gastric Sleeve Surgery.

Gastric sleeve surgery is a frequently performed procedure. Although it is one of the safest bariatric procedures, it is like any other operation that carries significant risks and complications. Moreover, the hepatic abscess is an infrequent complication of laparoscopic gastric sleeve surgery, the infected late gastric leakage is a rare etiology of the hepatic abscess. We present a case of liver abscess developed one month after sleeve gastrectomy secondary to infected walled-off late-gastric leak. The case highlights this rare complication of gastric sleeve surgery. Moreover, early treatment of liver abscesses with imaging-guided drainage and intravenous antibiotics can prevent life-threatening outcomes.

Metastatic Mucinous Adenocarcinoma of Gastrointestinal Origin: A Rare Presentation of Peritoneal Carcinomatosis in a Woman.

Peritoneal carcinomatosis is most commonly a rare late-stage manifestation of disseminated ovarian cancer. Women with peritoneal carcinomatosis with no obvious primary tumor are presumptively treated for ovarian cancer. However, less frequently, gastrointestinal cancer disseminates to the peritoneum, which would confer other treatment options. Herein, we present a case of a 68-year-old woman who was managed for peritoneal carcinomatosis of metastatic mucinous adenocarcinoma of lower gastrointestinal origin.

A Case of Severe Dilated Cardiomyopathy and Hyperthyroidism.

Hyperthyroidism often leads to heart failure when left untreated, specifically high output heart failure and left ventricular (LV) hypertrophy. A very minimal portion of those develop severe LV dysfunction. We report a case of a 65-year-old male who presented with signs and symptoms of heart failure and was found to have hyperthyroidism, severe systolic dysfunction, and severe dilated cardiomyopathy. The patient is a 65-year-old African American male with a history of hypertension (HTN) who presented with complaints of dyspnea on exertion and bilateral lower limb edema of one-week duration. A review of systems revealed paroxysmal nocturnal dyspnea, orthopnea, palpitations, fatigue, and weight loss. Physical exam showed tachycardia but otherwise no exophthalmos, no thyromegaly, no thyroid nodules, clear lungs, normal heart sounds, regular heart rhythm, normal reflexes, and 2+ edema of bilateral lower extremities up to the knees. Labs showed elevated B-natriuretic peptide, severely suppressed thyroid-stimulating hormone, elevated free triiodothyronine (FT3), and free thyroxine (FT4). Electrocardiogram (EKG) revealed sinus tachycardia, incomplete left bundle branch block, and non-specific T wave abnormality. Echocardiography revealed abnormal (LV) structure and function, with moderate to severe dilatation without LV hypertrophy, severe LV systolic dysfunction with ejection fraction (EF) 30-35%, and an abnormal LV diastolic function. The patient was managed with diuresis for acute onset heart failure and with beta-blocker and methimazole for symptomatic hyperthyroidism. Thyroid assessment is an important step in evaluating any patient with suspected heart failure. This case highlights the balance that should exist between treating hyperthyroidism symptoms and managing disease states such as acute heart failure.

Status Epilepticus as a Life-Threatening Manifestation of Myxedema Crisis.

Myxedema coma is a rare life-threatening emergency that usually presents in the elderly during the winter months. The neurological changes caused by uncontrolled hypothyroidism may precipitate seizure activity and its deleterious consequences. A 65-year-old homeless man with a history of non-Hodgkin lymphoma in remission for over 20 years presented to the emergency department (ED) following an episode of syncope. His physical examination was remarkable for hypothermia and bradycardia. Shortly after the admission, he had two tonic-clonic seizures with sphincter relaxation and no recovery between the convulsions. His thyroid-stimulating hormone (TSH) level was 304 uIU/ml. He received appropriate treatment for his condition and was discharged after a full recovery. This case illustrates the catastrophic consequences of long-term uncontrolled hypothyroidism. A high index of clinical suspicion is essential for beginning prompt hormone supplementation in such patients.

Life-threatening sustained hypocalcemia following Denosumab use in metastatic prostate cancer.

INTRODUCTION: Prostate cancer is the second most frequently diagnosed cancer among men worldwide in 2020. Skeletal-related events (SRE) like pathologic fracture or spinal cord compression are commonly seen in metastatic prostate cancer. Denosumab, a monoclonal antibody, acts by inhibiting osteoclast-mediated bone resorption in bone metastasis from solid tumors and reduces bone turnover and destruction. However, there is an increased risk of life-threatening denosumab-induced hypocalcemia with an incidence of 0.1 to 12.8%. CASE REPORT: Our patient is a 69-year-old man with widespread skeletal metastatic disease from primary prostate cancer who presented to the hospital complaining of generalized fatigue and joint pain. Due to severe debilitating low back pain secondary to osteochondral lesions, the patient was started on Denosumab 120 mg. On presentation, serum calcium was found to be severely low at 5.9 mg/dl (serum calcium level prior to Denosumab was 9.1 mg/dl). MANAGEMENT AND OUTCOME: Denosumab was discontinued immediately, and the patient was started on IV calcium gluconate. Repeat serum calcium level continued to be low at 6.7 likely due to the long elimination half-life of Denosumab (25-30 days). He was transferred to a long-term acute care facility for long-term IV calcium replacement, where he succumbed to illness six weeks later. DISCUSSION: Denosumab, an anti-resorptive treatment for skeletal metastasis from solid tumors, is shown to cause severe life-threatening hypocalcemia. The maximum serum drug level of Denosumab reaches 7-21 days after administration. Sustained hypocalcemia is rare and life-threatening. Clinicians should use this medication with caution due to its unpredictable side effect profile.

Spontaneous pneumomediastinum: A collaborative sequelae between COVID-19 and self-inflicted lung injury - A case report and literature review.

Spontaneous pneumomediastinum is an infrequent complication of COVID-19. The mechanism is still unknown and thought to be related to patient self-inflicted lung injury. Our patient is a 49-year-old male who presented with shortness of breath and cough. A COVID-19 Polymerase Chain Reaction was positive. He required a high-flow nasal cannula, but he did not demand mechanical ventilation. Computed tomography angiography scan of the chest revealed pneumomediastinum. He was managed conservatively, and a complete recovery was achieved. This case highlights the emerging association of COVID-19, patient self-inflicted lung injury, and pneumomediastinum. Furthermore, spontaneous pneumomediastinum should be suspected even in patients who were not mechanically ventilated.

Azithromycin-Induced Liver Injury in Legionnaires' Disease.

Drug-induced liver injury (DILI) is the leading cause of acute liver failure in the United States. Azithromycin is a commonly used antibiotic for community-acquired pneumonia that causes liver injury in rare cases. Typically, cholestatic liver injury has been reported for azithromycin, but there have only been a few case reports addressing the association with direct hepatocellular liver injury. This is a case of a 66-year-old man, with no pre-existing liver disease, who was managed for Legionnaires' disease who sustained a hepatocellular pattern of liver injury associated with azithromycin. We report this case to highlight the importance of prompt recognition of these rare side effects associated with azithromycin and the discontinuation of the drug to facilitate rapid recovery.

COVID-19, Necrotizing Pancreatitis, and Abdominal Compartment Syndrome: A Perfect Cytokine Storm?

Coronavirus disease 2019 (COVID-19) induces a dysregulated immune response, leading to a drastic elevation of proinflammatory cytokines. This cytokine storm has the potential to aggravate any prior ongoing inflammation. Moreover, acute pancreatitis can cause local necrosis, thereby causing extensive abdominal inflammation. This condition increases the risk of abdominal compartment syndrome (ACS) and its deleterious consequences. We report the case of a 37-year-old male with a past medical history of chronic pancreatitis and alcohol use disorder who presented to the emergency department complaining of abdominal pain. Physical examination revealed a tender abdomen. Initial workup showed elevated amylase and lipase, a positive COVID-19 polymerase chain reaction (PCR) test, and elevated inflammatory markers. The patient denied any respiratory symptoms. Initial abdominal CT scan revealed mild pancreatic inflammation. The patient was admitted to the respiratory ICU and managed with fluid resuscitation and pain control. However, the patient had increasing oxygen requirements, leukocytosis, and worsening kidney function. A trans-bladder measurement of intra-abdominal pressure revealed severe ACS. Broad-spectrum antibiotics were started; however, after 72 hours of treatment, the patient had a cardiopulmonary arrest. He returned to spontaneous circulation after advanced cardiovascular life support (ACLS) protocol and intubation. A repeat CT scan of the abdomen showed necrotizing pancreatitis with a large-volume hemoperitoneum. Urgent pancreatic necrosectomy was performed with drainage of the hemoperitoneum. The patient was transferred to a long-term acute care facility for extended antibiotic therapy where he eventually recovered. This case illustrates the catastrophic consequences of necrotizing pancreatitis complicated by sepsis and ACS in a COVID-19-positive patient.

A Case of Focal Segmental Glomerulosclerosis With Immune Complexes: Is HIV, Hepatitis B, or Crack the Culprit?

Human immunodeficiency virus (HIV)-positive individuals are at an increased risk for kidney diseases, including HIV-associated nephropathy (HIVAN), focal segmental glomerulosclerosis (FSGS), HIV immune complex disease of the kidney (HIVICK), and acute tubular necrosis (ATN). Non-modifiable factors such as age and genetics, as well as modifiable factors such as illicit drug use and compliance, define the progression to renal failure. The patient is a 64-year-old African American male with HIV, treated latent syphilis, chronic kidney disease stage 3a, and cocaine use disorder who presented with shortness of breath, bilateral lower extremities swelling, and fatigue with normal vitals and a physical exam remarkable for bibasilar inspiratory crackles with peripheral edema. Laboratory tests showed creatinine (Cr) of 2.23 mg/dL with a baseline of 1.5 mg/dL, albumin of 1.8, blood natriuretic peptide (BNP) of 667.88, and lipidemia. His urine was remarkable for proteinuria and microalbuminuria in the presence of cocaine. Immunofixation electrophoresis showed a marked increase in IgG and IgM, free lambda, and free kappa/free lambda ratio with HIV viral load of 39,400 copies/ml, absolute CD4 count of 56, and an acute hepatitis B panel. Renal biopsy confirmed HIVAN with FSGS accompanied by collapsing features, HIVICK, and ATN. The patient was subsequently started on highly active antiretroviral therapy (HAART) with prophylactic antibiotics and close monitoring.

A Rare Case of Gemella haemolysans Infection of Knee Arthroplasty.

Gemella haemolysans is a facultative, catalase-negative, anaerobic, gram-positive cocci. It is known to mostly cause endocarditis, meningitis, peritonitis, and cerebral abscesses. However, it is extremely rare for this organism to cause infections of an orthopedic nature, with only a single report of infection in total knee arthroplasty (TKA). We present a rare case of knee arthroplasty infection caused by G. haemolysans four years after an uncomplicated TKA procedure.

Zonisamide-Induced Hallucinations: An Anticonvulsant's Psychosis.

Zonisamide is a new-generation anticonvulsant that works by altering the sodium and T-type calcium channels in the brain. It is currently approved for partial seizures, and trials are ongoing to evaluate the effectiveness against mania and chronic pain in adults. Psychosis is a rare side effect with an incidence of 2%. Our patient, a 52-year-old female with a past medical history of osteoarthritis and chronic pain only relieved by zonisamide is brought to the emergency department (ED) after a two-day history of altered mental status, agitation and visual hallucinations. One month prior, she had undergone total knee arthroplasty complicated with right knee cellulitis managed by IV (intravenous) long-term antibiotics of vancomycin and ertapenem. Physical examination was remarkable for disorientation to person, place, and time with intact remainder of the neurological exam. Initial laboratory work was unremarkable and a computerized tomography (CT) scan of the brain showed no acute intracranial abnormalities. The patient was treated as ertapenem-induced with altered mental status and the antibiotic was switched to meropenem upon discharge. Two weeks later, the patient presented to the ED with similar non-resolving complaints. As the patient's symptoms didn't improve after ertapenem discontinuation, the decision was made to stop zonisamide and carefully monitor for possible withdrawal symptoms. Progressively, our patient had a timely resolution of symptoms with a full return to baseline within a week. This case demonstrates the potential severity of zonisamide-induced psychosis. Additional studies are warranted to analyze the mechanism explaining its neurological side effect profile.

Arnold-Chiari Malformation and Scoliosis: A Chronic Lung Collapse Mimicking Sepsis.

Scoliosis is a deformity of the spine caused by excessive lateral curvature. Compared to other variants, neuromuscular scoliosis is more likely to progress, altering the body's normal architecture in a relatively short period of time. Furthermore, patients with Arnold-Chiari malformation or Chiari malformation (CM) type 2 have intrinsic neurological complications that might entangle the initial clinical assessment. A 24-year-old woman with a history of scoliosis and CM type 2 status post-tracheostomy was admitted from a skilled nursing facility after a one-day history of low blood pressure, leukocytosis, and an outpatient chest X-ray suspicious for pneumonia. Physical examination was remarkable for hypotension and decreased breath sounds at the left pulmonary base. A tracheostomy tube and central venous catheter were noticed. Initial laboratory results revealed leukocytosis with borderline bandemia and a chest X-ray with a left lower lung consolidation. She was treated as a case of sepsis, for which broad-spectrum antibiotics were immediately started. However, upon review of charts, the patient's objective findings were similar to a previous admission. Chest computed tomography scan revealed atelectasis in the left lower lung with no signs of consolidation, effusions, or abscesses. After extensive workup, no identifiable cause was found to suggest an acute process. Antibiotic therapy was halted and the patient was discharged to her nursing home. This case presents a patient with CM type 2 and scoliosis complicated by chronic and worsening atelectasis. Accurate initial assessment and communication between providers are paramount to avoid overtreatment.
