'TAVR Infected Pseudomonas Endocarditis': a case report.

Pseudomonas aeruginosa (P. aeruginosa) rarely causes infective endocarditis (IE), previously reported for approximately 3% of all patients with IE.1 Most commonly, the infection occurs in intravenous drug users (IVDU) as right-sided endocarditis, noting presentations of P. aeruginosa IE without history of intravenous drug to be extremely rare, finding only a few cases reported in the literature. However there are increasing reports of cardiovascular implantable electronic device-related and prosthetic heart valve infections caused by this pathogen in non-IVDUs.2 This report will focus on the clinical presentation, management, and outcome of P. aeruginosa endocarditis in an 89-year-old patient with a transcatheter aortic valve replacement (TAVR). Medical management was pursued due to the patient's underlying comorbidities. Long-term suppressive antibiotic therapy with delafloxacin was successful in maintaining negative blood cultures, despite an allergy to levofloxacin and ciprofloxacin. Plain Language Summary: An 89-year-old male was admitted to our hospital after he was diagnosed with a blood stream infection. The initial identification noted gram-negative organisms consistent with Pseudomonas Aeruginosa so the patient was started on intravenous (IV) antibiotics. He improved after the antibiotics started and was discharged to a nursing facility to complete his antibiotics course. While at the facility, after he had finished his antibiotics, he started to become ill again. He was brought back to the hospital to be evaluated. His repeat blood cultures again grew P. Aeruginosa. This suggested that his infection had not been cleared the first time and most likely he had a source of bacterial growth. A few years prior, a transcatheter aortic valve replacement (TAVR) had been performed for the patient. This was suspected as the source of continued infection and so a transthoracic echocardiogram was obtained, which revealed vegetation on the TAVR. We also obtained a magnetic resonance imaging (MRI) of the brain, which demonstrated infarcts of several portions of the brain consistent with emboli. Due to his age and additional medical issues, the patient was not a candidate for surgical valve replacement. We decided to try medical therapy with a fluoroquinolone antibiotic since the bacteria was susceptible to it. Unfortunately, he had demonstrated allergies to the usual choices to include Levaquin and ciprofloxacin. Therefore, we elected to start him on a new fluoroquinolone agent that had recently been FDA approved and obtained by our facility called delafloxacin. The patient tolerated this well and his repeat blood cultures remain clear. After discussion with the infectious disease specialist, he requires a lifelong suppression with the medication since the TAVR cannot be removed. This case is meant to illustrate the effectiveness of medical therapy when surgical options are not available.

Partial Gastric Resection for Symptomatic Anemia following Diagnosis of Merkel Cell Carcinoma (MCC) of the Skin with Gastric Metastasis.

Merkel Cell Carcinoma (MCC) is a rare dermatologic malignancy with significant morbidity and mortality associated with metastatic disease. In this case, we discuss and extremely rare presentation of MCC with metastasis to the stomach in a patient that presented with profound anemia. Unfortunately, mortality following diagnosis of MCC with gastric metastasis approaches 67% at 4 months based on available published reports. Due to its rarity and high rate of mortality, there is a lack of available research and literature to help guide treatment of this rare presentation of MCC. This case report presents a positive outcome associated with a partial gastrectomy for the treatment of symptomatic MCC with gastric metastasis and continued survival with persistently stable hemoglobin at 12 months. Key clinical message: Anemia may be a significant cause of the morbidity and mortality associated with MCC with gastric metastasis. Our case demonstrates a positive outcome associated with partial gastric resection and presents a possible treatment option for this rare disease process.

A Case of Spontaneous Pneumomediastinum in Covid-19 Pneumonia.

Spontaneous pneumomediastinum (SPM) is defined as free air in the mediastinum thought to be due to non-traumatic rupture of marginal alveoli without evidence of underlying lung disease. Secondary causes must be excluded, including perforations of the esophagus, trachea, and bronchi, due to their propensity for unfavorable outcomes. Infectious etiologies have been documented to cause pneumomediastinum, but this is most frequently observed in the setting of mechanical and noninvasive positive-pressure ventilation (NIPPV). Here we present a case of asymptomatic spontaneous pneumomediastinum in a patient with COVID-19 in absence of mechanical ventilation.

'When Cryptococcus strikes and lupus is found': a unique covert unveiling of systemic lupus erythematosus presenting as subacute meningitis.

Cryptococcal neoformans is a rare fungal pathogen that has been associated with immunocompromised individuals. Due to its rare occurrence, clinicians have a low index of suspicion for diagnosis, which can lead to increased morbidity and mortality. We present an 81-year-old fully functional woman with no known predisposing risk factors or previous immunocompromising conditions who was found to have cryptococcal meningitis on cerebrospinal fluid analysis in the setting of newly diagnosed uncontrolled type 2 diabetes and systemic lupus erythematosus (SLE).

COVID-19-induced psoriatic arthritis: a case report.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which may lead to uncontrolled immune activation and cytokine response in some. The pattern of pro-inflammatory cytokines is similar to that which has been observed to be involved in rheumatic diseases and target treatments. Viral arthritis is common with a wide variety in spectrum ranging from arthralgia to spurious and chronic arthritis. However, recent studies have demonstrated a correlation with endemic coronaviruses and increased risk of developing rheumatoid arthritis (RA). Cases are being identified that describe a post-COVID reactive; however, to date, no report has been published describing the onset of psoriasis and concomitant development of psoriatic arthritis after COVID-19 infection. We report an interesting case of psoriatic arthritis in a post-COVID-19 infection patient with review of the current literature.

Sailing the ship of life: scurvy and autoimmunity . . .

Celiac disease (CD) is a multisystem disorder known to manifest in a multitude of ways to include diarrhea, anemia, and nutritional deficiencies. The malabsorptive state can present as certain classical conditions such as autoimmune gastritis and osteopenia/osteoporosis but scurvy is less recognized within the literature. In this case, we present a unique presentation of scurvy as a result of an undiagnosed CD.

Nocardia asteroides occipital abscess as a cause of lupus nephritis?

Systemic lupus erythematosus (SLE) is a multisystem disease with a complex etiology, which manifests in a multitude of manners. We present a case of lupus nephritis in a patient who developed complications of immunosuppressive treatment with eventual resolution of her nephritis following cure of her Nocardia brain abscess.

Appendiceal disease in hematopoietic cell transplantation.

Appendiceal diseases are rare reported complications during hematopoietic stem cell transplantation with no guidance on management in the published literature. Medical therapy may be considered in selected patients prior to surgical solutions.

Testicular Rupture: The Other Nutcracker Syndrome.

Scrotal trauma is a rare incident but when it occurs it is typically among 6 to 12 years old boys. It is most commonly unilateral secondary to compression of the scrotal contents against the pubic bone. The majority of trauma to the scrotal region is blunt impact but serious injuries are rare despite the vulnerable position of the testicles. The combination of the cremasteric reflex and mobility/strength of the tunica albuginea contribute to reducing occurrences. However, serious injury can occur when the testicle is trapped against the pubic bone, varying from minimal extravasation to complete parenchymal destruction. Testicular rupture is a rare injury characterized by rupture of the tunica albuginea resulting in exposure of the seminiferous tubules. Prompt evaluation of these patients is crucial as a delay in surgical care may lead to loss of the injured testicle. We present a case of acute testicular rupture in an active duty male followed by a review of the literature.

Helicobacter pylori-negative extra-nodal marginal zone B-cell lymphoma of Mucosa-Associated Lymphoid Tissue (MALT) type following Roux-en-Y Gastric Bypass (RYGB).

Gastric MALT lymphoma is a common type of non-Hodgkin's lymphoma that has the potential for cure in patients found to have concomitant Helicobacter pylori (H. pylori) infection. This case report explores the evaluation, diagnosis, and treatment of H. pylori-negative MALT lymphoma in a patient with a history of a RYGB.

'Granulomatosis with polyangiitis after Pfizer vaccination': a case report.

The advent of COVID-19, caused by the SARS-CoV-2 virus, has resulted in over 541 million cases with 6.32 million deaths worldwide as of June 2022. The devastating consequences of this global pandemic resulted in the expedited generation of mRNA-based vaccines such as the Pfizer-BioNTech and Moderna vaccines. Although the vaccines have been effective, with recent data indicating greater than 95% effectiveness, rare complications have been reported, including manifestations of autoimmune phenomena. Herein, we report a rare case of Granulomatosis with polyangiitis (GPA) in an active duty military male soon after receiving the first dose of the Pfizer-BioNTech COVID-19 vaccine.

A 27-year-old active duty marine was admitted to our hospital after being transferred from Hawaii with concern of new autoimmune disease after receiving the Pfizer vaccine. The patient initially presented to the emergency department with joint pain, fever, chest pain, hemoptysis, and a nose bleed. A comprehensive workup demonstrated elevated inflammatory markers, progressive renal dysfunction, and a positive antibody panel consistent with antineutrophil cytoplasmic antibodies (ANCA) vasculitis. Due to the limited capabilities in his deployed setting, he was transferred to our hospital for a higher level of care. We performed some additional tests to include computed tomography (CT) imaging of his lungs and a renal biopsy which came back consistent with GPA. The patient was started on high-dose prednisone and rituximab, and he achieved remission. He was discharged from the hospital with follow-up arranged with rheumatology and nephrology. He remained in remission on follow-up.

A rare presentation of an ACTH-producing high-grade large cell neuroendocrine carcinoma with Cushing's syndrome.

High-grade neuroendocrine tumors (HGNET) are rare neoplasms composed of neural and hormonal with only around 42 cases reported in the last 20 years1. Herein, we describe a rare case of pancreatic HGNET, large cell type, associated with a Cushing's syndrome presentation.

Fevers, Sweats, Weight Loss, Oh My! When IgG4 Related Disease Comes Knocking. . .

Immunoglobulin G4-related systemic disease (IgG4-RSD) is a fibro-inflammatory immune condition characterized by IgG4 positive plasma cells, fibrosis, and frequently elevated serum IgG4 level. Akin to sarcoidosis, IgG4-RSD is a systemic disease with diverse organ manifestations linked by common histopathologic features. IgG4-RSD typically presents sub acutely without significant constitutional symptoms or fever. Hepatic Inflammatory pseudotumor (HIP) is a rare manifestation of IgG4-RSD composed of dense lymphoplasmacytic infiltrate and extensive fibrosis. We present an older Asian male who presented with acute onset of fever and weight loss found to have IgG4-RSD complicated by a HIP and concomitant MSSA abscess.

Cutaneous ulcers in association with sprue-like enteropathy secondary to Losartan.

Losartan is an angiotensin II receptor blocker (ARB) which may cause severe sprue-like enteropathy (SLE) with skin manifestation. Clinicians should be informed of this side effect and its reversibility after cessation of the drug.

Recurrent pneumonia with persistent peripheral eosinophilia: Idiopathic chronic eosinophilic pneumonia.

Although ICEP is an exceptionally rare disease, it is potentially overlooked and misdiagnosed. This case highlights the importance of peripheral eosinophilia in raising suspicion for ICEP. Without treatment, majority of patients fail to improve.

Meckel's Diverticulum Strangulation.

Meckel's diverticulum is the most common congenital anomaly of the small intestine. It is a true diverticulum containing all layers of the intestinal wall and results from the incomplete resolution of the omphalomesenteric duct. The majority of the cases are asymptomatic; however, diagnostic challenges arise when it becomes inflamed, causes gastrointestinal hemorrhage, intestinal obstruction, or when it protrudes through a potential abdominal opening (Littre's hernia). We present a rare case of strangulated Meckel's diverticulum as a result of axial torsion presenting with right lower quadrant abdominal pain.

Coccygeal Polypoid Eccrine Nevus Presenting as a Skin Tag: Case Report and Review of the Literature.

Coccygeal polypoid eccrine nevi (CPEN) are rare, benign, cutaneous polypoid lesions localized to the coccyx region that are characterized by areas of hyperplastic eccrine ducts without hyperhidrosis. We present the case of an asymptomatic 16-month-old female with a congenital lesion in the lower sacral area and review the literature and the differential diagnosis for CPEN.

Therapeutic Hypothermia to Treat a Newborn With Perinatal Hypoxic-Ischemic Encephalopathy.

Hypoxic-ischemic encephalopathy is caused by neonatal asphyxia and can lead to mortality or long-term neurodevelopmental morbidity in neonates. Therapeutic hypothermia (TH) is one of the few effective ways to manage mitigating neurologic sequelae. The authors describe the case of a neonate who had a perinatal hypoxic insult and sustained no long-term sequelae after being treated with TH. It is important that osteopathic physicians who provide obstetric and gynecologic, perinatal, and emergency medical care are able to recognize a perinatal hypoxic event, understand the stratification of hypoxic-ischemic encephalopathy risk factors, and implement early TH protocols.

Patterns of injury and outcomes associated with motocross accidents.

Motocross has become a popular recreation activity in Southern California, particularly in the Inland Empire area. In order to evaluate the patterns of injury and outcomes associated with motocross accidents, the Trauma Registry data and charts of all patients with motocross-related injuries from January 2000 to December 2001 were reviewed. Of the 270 patients studied, 265 were males and 5 were females, with a mean age of 26 years (range, 5-61). The mean Injury Severity Score was 6.8 (range, 1-38). Injuries involved extremity trauma in 52 per cent of patients closed head injuries in 33 per cent, blunt chest trauma in 23 per cent, abdominal trauma in 15 per cent, spinal trauma in 14 per cent, and pelvic trauma in 8 per cent. Surgery was required in 96 patients (36%), most commonly for treatment of orthopedic injuries. After initial evaluation, 179 patients were admitted (66%), 60 were discharged home (22%), 29 were transferred for higher level of care (11%), and two expired (1%). The mean hospital length of stay was 2.3 days (range, 1-9). Motocross accidents are most commonly associated with extremity injuries and closed head trauma. Although the overall mortality is low, the morbidity is high, with a large proportion of patients requiring surgery.

Laparoscopic splenectomy for chronic recurrent thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is a serious hematologic disorder with a high rate of morbidity and mortality when it fails to go into remission. The primary treatment is total plasma exchange. The addition of corticosteroids, chemotherapeutic agents, or antiplatelet agents is of unproven benefit, and splenectomy has been offered as salvage therapy in refractory cases. We performed laparoscopic splenectomy (LS) on two patients with chronic refractory TTP. The early and late postoperative courses, including hematologic data, are presented here. The mean duration of surgery was 113 minutes and the mean estimated blood loss was 35 mL. Mean hospital stay was 1.5 days. The early postoperative platelet count showed an immediate rise in both patients. After 19 months and 16 months of follow-up, respectively, both patients remain in remission without further episodes of TTP. Laparoscopic splenectomy is a safe and effective therapy for patients with chronic relapsing and refractory TTP. The inherent benefits of the minimally invasive approach, its low morbidity, short hospital stay, and faster recovery, are significant advantages for these patients.
