This case of infective endocarditis masquerading as mixed cryoglobulinemia in a man with a history of intravenous drug use (IVDU) and hepatitis C virus (HCV) highlights the importance of maintaining a broad differential and continually re-evaluating the working diagnosis as new information presents itself. The patient presented to an outside hospital and was treated for presumptive mixed cryoglobulinemia with corticosteroid therapy. When the patient did not improve, he was transferred to a tertiary care center for possible Rituximab and/or plasmapheresis...

We report a case of bronchoesophageal fistula associated with tuberculosis. A 25 year old woman presented to us with 3 month history of cough worsening with deglutition. Radiological examination revealed mediastinal lymphadenopathy and bronchoscopy with esophagoscopy confirmed the presence of fistulous communication with features of endobronchial tuberculosis. Histological examination of bronchial biopsy specimen showed non necrotic granuloma with the PCR positive for Mycobacterium tuberculosis in her bronchial secretions...

The global re-emergence of syphilis is an exigent public health issue requiring both clinicians and public health practitioners to become familiar with the myriad manifestations of this great imitator. This report describes a case of an originally undiagnosed chronic oral syphilitic chancre, subsequently confirmed by both PCR and immunohistochemistry.

C Duployez, C Loïez, G Ledoux, S Armand, E Jaillette, F Wallet
Moraxella nonliquefaciens is a Gram-negative coccobacillus considered as a commensal organism from the upper respiratory tract, with low pathogenic potential. The phenotypical conventional identification is difficult and the matrix-assisted laser desorption/ionization time-of-flight technology has increased the resolution of identification of this bacterium. We report a fatal case of endocarditis due to M. nonliquefaciens whose identification was confirmed by 16S rRNA, and we review the literature on this pathogen in endocarditis...

INTRODUCTION: Raoultella planticola is a gram-negative rod associated with soil and aquatic environments that has rarely been associated with human infections. PRESENTATION OF CASE: We present the case of a 73 year old female with multiple myeloma and recurrent Clostridium difficile infection who was found to have a urinary tract infection with Raoultella planticola, which has only been reported to cause 29 cases of human infections and 2 cases of urinary tract infections...

Hemolytic uremic syndrome (HUS) is a well-described process that is known to cause severe renal dysfunction, thrombocytopenia, and anemia. HUS is typically associated with toxins (shiga-like and shigella toxin) found in strains of E. coli and Shigella spp [1], [2], [3]. We present a case of a 27 year-old man with jaundice, thrombocytopenia, and renal dysfunction who was found to have HUS in the setting of Shigella sonnei infection. Outside of developing countries, cases of HUS related to S. sonnei are largely unreported...

We report a case of an intravenous drug user (IVDU) patient who had 4 episodes of endocarditis within a 2-year time period in rural Georgia. The institutional cost was approximately $380,000. The lack of an established transitional care plan for IVDUs to outpatient care is a common phenomenon at institutions. Guidelines are essential to optimize the quality of care rendered to IVDUs with such infections, to assist providers in utilizing limited resources, and to limit the cost to the institutions.

Streptococcus canis (Sc) is a zoonotic pathogen that is transferred mainly from companion animals to humans. One of the major virulence factors in Sc is the M-like protein encoded by the scm gene, which is involved in anti-phagocytic activities, as well as the recruitment of plasminogen to the bacterial surface in cooperation with enolase, and the consequent enhancement of bacterial transmigration and survival. This is the first reported human case of uncomplicated bacteremia following a dog bite, caused by Streptococcus canis harboring the scm gene...

Lawrence Ha, Negin Niknam, Siddhi Mankame, Robin Koshy
Aerococcus urinae, a previously misidentified pathogen, has become increasingly recognized to cause severe and even fatal infections. Aerococcus-related perineal abscess infections have not previously been reported in the literature. Most reported cases of infections caused by Aerococcus are urinary tract infections, bacteremia, and even rare cases of endocarditis. We report an unusual case of a perineal abscess caused by Aerococcus urinae.

Rhinosporidiosis is a chronic granulomatous mucocutaneous disease that is endemic in South Asia. It commonly affects men in the second to fourth decade of life. The most common site of infection is the nose or nasopharynx with primary involvement of the parotid duct noted very rarely; only four cases reported in literature. We report a case of a 77 year old male patient who presented with a subcutaneous cheek swelling with no other clinical features to suggest the diagnosis of rhinosporidiosis. An unusual affliction in a patient in the seventh decade of life, at a site not reported previously with no past history of the same makes it imperative to ascertain the known facts about both the organism and the disease...

Q fever is a worldwide zoonotic infection caused by the obligate intracellular bacterium Coxiella burnetii that can course with acute or chronic disease. This series describes 7 cases of acute Q fever admitted in a Portuguese University Hospital between 2014 and 2015. All cases presented with hepatitis and had epidemiological history. Diagnosis was done by PCR on majority (5) and by serology and PCR in only 2. Serological tests can be negative in the initial period of the disease. Molecular biology methods by polymerase chain-reaction are extremely important in acute disease, allowing timely diagnosis and treatment...

A 45-year-old man was admitted for investigation of a symmetric lower limb rash associated with recurrent fever for two weeks following a hiking trip in Italy and Greece. He was treated for sepsis secondary to lower limb cellulitis with no clinical improvement and subsequently diagnosed with Streptococcus gallolyticus endocarditis mediating an infectious vasculitis.

65 year-old-male presented with a one-week history of high grade fever, fatigue and confusion which began abruptly two days after a cystoscopy procedure. Past medical history included pulmonary sarcoidosis diagnosed by mediastinal lymph biopsy, diabetes and hypertension. On admission he was febrile and confused with stable vital signs. Initial workup included negative Head CT and lumbar puncture. Blood work revealed normal metabolic and liver function tests with progressive anemia, thrombocytopenia and atypical lymphocytosis of 15-20%...

Cutaneous hyperpigmentation is a recognized adverse effect of chronic minocycline use occurring in up to 50% of patients. In this report we present a rare case of extensive skin hyperpigmentation involving both lower extremities in a patient receiving long term minocycline. The patient was receiving minocycline as suppression for chronic prosthetic joint infection. Risk factors associated with minocycline-induced cutaneous pigmentation (MICH) will be reviewed.

We report the case of an immunocompetent man who presented with fever and abdominal pain and was found to have a hepatic abscess and a peri-renal abscess with a computerized tomography scan. The hepatic abscess was drained percutaneously and cultures revealed the presence of Lactococcus lactis that was sensitive to penicillin. The patient was successfully treated with ceftriaxone and metronidazole with resolution of the abscesses. Further work-up revealed atrophic gastritis, vitamin B12 deficiency, periodontitis and gingivitis, suggesting a possible site of entry for the development of the abscesses...
