A Unique Case of Moraxella catarrhalis Meningitis Following Neurosurgical Intervention.

We present a rare case of Moraxella catarrhalis meningitis in a 51-year-old immunocompetent woman after surgical resection of a fourth ventricle ganglioma. Notably, the patient had no history of sinusitis or otitis media, which are typical predisposing factors for Moraxella infection. She developed symptoms including headache, altered mental status, and neurological deficits three days post discharge, leading to her diagnosis confirmed by cerebrospinal fluid culture. This case highlights the diagnostic challenges and management complexities of atypical meningitis post neurosurgery. The occurrence emphasizes the necessity of considering Moraxella catarrhalis in differential diagnoses, particularly following neurosurgical procedures. This instance contributes to the scarce documentation of such infections in immunocompetent adults, underscoring the importance of vigilant microbiological evaluation and tailored antimicrobial therapy in postoperative settings.

Successful Management of Pasteurella multocida Pneumonia in a Chronic Obstructive Pulmonary Disease Patient: A Case Report Highlighting the Importance of Tailored Antibiotic Therapy.

This report describes a patient with Pasteurella multocida pneumonia. The patient was a man in his 70s with significant comorbid conditions, including chronic obstructive pulmonary disease (COPD), and is an example of the diverse presentations of P. multocida infections increasingly found in the literature. The novelty of this case lies in the manifestation of P. multocida pneumonia in a patient with underlying respiratory conditions and its successful management, outlining a unique clinical scenario and a tailored therapeutic approach. A 71-year-old male with a medical history of COPD, asthma, tremors, hypertension, and arthritis presented to the emergency department with progressive shortness of breath, productive cough, and chest tightness. The initial diagnosis was COPD exacerbation and left lower lobe pneumonia, for which a regimen of ceftriaxone and azithromycin was initiated. The patient's condition was further complicated by the persistence of symptoms. Following sputum culture analysis, P. multocida infection was identified. Consequently, the antibiotic regimen was tailored, transitioning the patient to doxycycline, which led to substantial clinical improvement, enabling discharge with a 10-day course of oral doxycycline. This case elucidates the importance of precise microbiological diagnosis in patients with complex respiratory conditions, as it guides more targeted antibiotic therapy. It highlights the need for clinical vigilance for atypical pathogens like P. multocida in patients with COPD exacerbations, especially when conventional treatment strategies yield suboptimal responses. The successful resolution of the pneumonia underscores the effectiveness of antibiotic stewardship guided by sputum culture findings.

Toxic shock syndrome associated with menstrual cup use.

Staphylococcal toxic shock syndrome is a rare but life-threatening condition. It occurs when Staphylococcus aureus bacteria colonizing the vagina of a healthy woman, produce toxic shock syndrome toxin 1 activating the immune system and leading to multiorgan failure. Menstrual cups also known as vaginal cups are usually used as alternatives to other intravaginal products for menstrual blood collection. In rare cases, they can also lead to toxic shock syndrome. We report a case of toxic shock syndrome associated with vaginal cup use in a healthy menstruating woman. The diagnosis was made based on the United States Centers for Disease Control and Prevention criteria of the syndrome and confirmed with a vaginal cultural growth of Staphylococcus aureus.

Propionibacterium acnes Infection after Craniotomy in a Young Adult with Subdural Hematoma.

Propionibacteriumacnes is a Gram-positive bacillus that can be part of the human skin flora. This bacterium infecting the subdural space postoperatively is quite a rare entity. When present, it likely reflects a true infection rather than contamination requiring urgent intervention. We are reporting a rare case of craniotomy for subdural hematoma evacuation complicated by subdural Propionibacterium acnes infection. The infection was successfully treated with surgical debridement and antibiotics.

New Onset Granulomatosis with Polyangiitis Associated with COVID-19.

The coronavirus disease 2019 (COVID-19) has recently been found to cause cutaneous vasculitis in patients. Granulomatosis with polyangiitis (GPA) is a type of small and medium vessel vasculitis that is often associated with pulmonary issues and has been shown to raise diagnostic complications in COVID-19 infection. In this report, we discuss the first case of new-onset GPA in the setting of active COVID-19 infection. Symptoms often overlap between the two diseases, and while there is no current cure for COVID-19, rapid immunosuppressive initiation can be lifesaving for patients with GPA. Thus, this case is essential in expanding our current knowledge of COVID-19 and its many skin manifestations.

Marked Elevation in Serum Procalcitonin Levels Do Not Correlate With Severity of Disease or Mortality in Hospitalized Patients: A Retrospective Study.

BACKGROUND: Bacteremia and sepsis are significant contributors to the morbidity, mortality, and economic burden of health care systems worldwide. Procalcitonin has been identified as a potentially useful marker of disease and severity in sepsis. However, the assumption that greater procalcitonin levels correlate with greater burden of disease has not been adequately studied. METHODS: A retrospective chart review of adult patients admitted to an urban teaching hospital with suspected sepsis was undertaken to test the association of elevated procalcitonin (>30 ng/mL) with other markers of sepsis (lactic acid, white blood cell count, percent bands), severity of disease (Sequential Organ Failure Assessment [SOFA] and Acute Physiology and Chronic Health Evaluation-II [APACHE II] scores), and mortality. RESULTS: In total, 168 patients were identified over 18 months (42% ward, 11% Stepdown, 44% medical intensive care unit [MICU], 2% surgical intensive care unit (STICU), 1% gynecology [GYN]). The Spearman correlation analysis showed that serum procalcitonin level did not correlate with SOFA (P = .238) or APACHE II (P = .918) scores on admission, and did not correlate with survival (Kruskal-Wallis test, P = .937). However, higher serum procalcitonin levels were associated with patients who had positive blood cultures (Kruskal-Wallis test, P = .0016 for Gram-positive and P = .0007 for Gram-negative bacteria). Lactic acid levels on admission strongly correlated with SOFA APACHE II (the Spearman correlation, P < .0001 for both) and mortality (P = .0001 for both). CONCLUSIONS: Higher serum procalcitonin levels above 30 ng/mL failed to correlate with indicators of sepsis, severity of disease (SOFA and APACHE II scores), and mortality but were associated with positive blood cultures. Lactic acid levels did show correlation to both severity of disease and mortality. Serum procalcitonin levels >30 ng/mL do not appear to correlate with the severity of disease in a sample of patients with markedly elevated initial procalcitonin levels.

Corynebacterium propinquum: A Rare Cause of Prosthetic Valve Endocarditis.

Nondiphtheria Corynebacterium species are often dismissed as culture contaminants, but they have recently become increasingly recognized as pathologic organisms. We present the case of a 48-year-old male patient on chronic prednisone therapy for rheumatoid arthritis with a history of mitral valve replacement with prosthetic valve. He presented with fever, dizziness, dyspnea on exertion, intermittent chest pain, and palpitations. Transesophageal echocardiography revealed two medium-sized densities along the inner aspect of the sewing ring and one larger density along the atrial surface of the sewing ring consistent with vegetation. Two separate blood cultures grew Corynebacterium propinquum, which were sensitive to ceftriaxone but highly resistant to vancomycin and daptomycin. The patient completed a course of ceftriaxone and repeat TEE study and after 6 weeks demonstrated near complete resolution of the vegetation. To our knowledge, this case represents the first in the literature of Corynebacterium propinquum causing prosthetic valve endocarditis. The ability of these organisms to cause deep-seated systemic infections should be recognized, especially in immune-compromised patients.

Coexistent Pseudogout and Mycobacterium avium-intracellulare Septic Arthritis in a Patient with HIV and ESRD.

Pseudogout is a crystal-induced arthropathy characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in synovial fluid, menisci, or articular cartilage. Although not very common, this entity can be seen in patients with chronic kidney disease (CKD). Septic arthritis due to Mycobacterium avium-intracellulare (MAI) is a rare entity that can affect immunocompromised patients such as those with acquired immunodeficiency syndrome (AIDS) or those who are on immunosuppressive drugs. Here, we describe a 51-year-old female who presented with fever, right knee pain, swelling, warmth, and decreased range of motion for several days. The initial assessment was consistent with pseudogout, with negative bacterial and fungal cultures. However, due to high white blood cell (WBC) count in the synovial fluid analysis, she was empirically started on intravenous (IV) vancomycin and piperacillin-tazobactam and discharged on IV vancomycin and cefepime, while acid-fast bacilli (AFB) culture was still in process. Seventeen days later, AFB culture grew Mycobacterium avium-intracellulare (MAI), and she was readmitted for relevant management. This case illustrates that septic arthritis due to MAI should be considered in the differential diagnosis of septic arthritis in immunocompromised patients.

Herpes zoster meningitis with multidermatomal rash in an immunocompetent patient.

A case of herpetic rash in an immunocompetent patient is described, which was present in multiple dermatomes at the same time. First, patient was thought to have immunodeficiency, but further workup turned out to be negative for it. Patient also had pleocytic lymphocytosis in cerebrospinal fluid, which was suggestive of viral meningitis. Later, the patient responded well to the acyclovir therapy and was discharged home without any sequel. This case illustrates the need for emergency physicians to be extra vigilant for involvement of other dermatomes in case a patient presents with herpetic rash in 1 dermatome because patients with multidermatomal/disseminated herpetic rash need to be started on airborne isolation in addition to contact precautions to prevent the transmission of disease in health care settings.

Cholera gravis associated with acute renal failure in a traveler from Haiti to the United States.

Cholera is a gastroenteric disease caused by epidemic or pandemic Vibrio cholerae which still is responsible for over 100,000 annual deaths worldwide. Since October 2010, Haiti experienced a cholera outbreak affecting more than 300,000 persons. Few imported cases related to the Haitian epidemic have been reported so far in the United States and Canada. We presented a patient who developed cholera gravis soon after arrival at New York City from Haiti. The patient needed admission to an Intensive Care Unit, for vigorous intravenous hydration, antibiotic therapy, and hemodialysis due to refractory oliguric renal failure. The patient was discharged the day 6 after admission and V. cholerae O1 was isolated from the stool culture. Cholera can be a life-threatening disease; early recognition based on travel history and clinical features is the corner stone for successful management.

An illustrative case of subcutaneous panniculitis-like T-cell lymphoma.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a very rare form of skin lymphoma that is localized primarily to the subcutaneous adipose tissue without palpable involvement of the lymph nodes. Diagnosis of SPTCL is a challenge, especially during its early phases when symptoms mimic other, more common conditions, such as benign panniculitis, eczema, dermatitis, psoriasis and cellulitis. Clinical and systemic features are nonspecific and can include fever, chills, and weight loss. Further complicating diagnosis is the high number of false negatives provided by biopsy. Here we present a case of SPTCL that illustrates the full course of the disease, from presentation and multiple misdiagnoses to correct disease recognition and successful treatment. A review of the challenges of diagnosis is provided with recommendations for more accurate and timely recognition of SPTCL.

Candida parapsilosis meningitis associated with shunt infection in an adult male.

Candida parapsilosis is a very rare cause of meningitis. Though several cases have now been reported in neonates and children, only one has been described in an adult. We report on a 55-year-old male that was admitted due to altered mental status. He had recent sinus drainage and polypectomy, craniotomy with drainage of brain abscess, and ventriculo-peritoneal shunt placement. On admission, imaging studies showed no evidence of shunt dysfunction but did reveal extensive white matter decreased attenuation. Microscopic examination of the first 10 daily cerebrospinal fluid (CSF) cultures revealed yeast. Flucytosine and liposomal amphotericin B were started and externalization of shunt was performed on day 3. On day 8, CSF culture from admission grew C. parapsilosis; fluconazole was added. On day 10, daily CSF still showed yeast and cultures consistently grew C. parapsilosis. Shunt was removed and bilateral ventriculostomy drains were inserted. CSF after procedure as well as at follow-up examinations throughout his 3-month hospitalization were negative for yeast. Extended treatment with flucytosine and fluconazole was initiated. At 8-month follow-up, successful treatment of C. parapsilosis infection without recurrence was confirmed. This case underscores the need for suspicion of C. parapsilosis as a cause of meningitis after invasive surgeries in adults.

Herpetic and candidal infections of the esophagus in an elderly male.

We present the unique case of an eighty-nine-year-old male without any immunodeficiency state or taking immunosuppressive medication and who did not have conditions affecting clearance of the esophageal lumen who was diagnosed with simultaneous herpetic esophagitis and candidal duodenitis.

Wegener's granulomatosis presenting as fever of unknown origin in an African-American male.

Wegener's Granulomatosis (WG) is a rare, Multisystem disease of the medium and small sized arteries and veins. It most commonly involves the upper respiratory tract, lungs, and kidneys and often presents as chronic fatigue, upper respiratory infection, sinusitis, and otitis media. Symptoms can include fever, weight loss and fatigue, though these are not usually the primary presenting complaints. development of the disease is highly skewed across ethnicities, with up to 98% of cases being reported in caucasians. We present the case of a 56-year-old African-American male who presented primarily with complaints of uncontrollable fever of unknown origin (FUO) for past two weeks with accompanying sore throat, nasal congestion, night sweats, malaise, and unexplained weight loss of 10 pounds over the past month. Treatment with antibiotics for one week prior to admission showed no relief of symptoms. Chest x-ray showed focal course markings in the right upper lobe. Urinalysis revealed microscopic hematuria and leukocyturia. Chest and abdominal CT scans revealed a right lower lobe pulmonary nodule and heterogeneous areas of enhancement in the spleen. Head CT revealed right mastoid opification. Labs revealed proteinase-3 antibody titer > 100, which is characteristic of WG. Steroids and cyclophosphamide were started with relief of presenting symptoms. Renal biopsy showed pauci-immune P-ANCA associated crescentic and focally necrotizing glomerulonephritis and vascilitis. This case is unique in that the patient presented with primary complaint of FUO. WG should be considered as a rule-out in cases of uncontrollable FUO, even if none of the classic triad of symptoms is present. Though rare, WG should be considered in cases involving non-Caucasian patients.
