A female, captive bred, juvenile swell shark ( Cephaloscyllium ventriosum ) was observed swimming in tight circles and rolling. Radiographs and computed tomography of this individual revealed extensive cartilage mineralization of the skull and cranial cervical vertebrae compared with diagnostic images of clinically healthy conspecifics. Gross necropsy and histopathologic examination revealed ossification and fibrosis of the cartilaginous matrix of the skull and cervical vertebrae with deep invasion by a pigmented hyphal fungus...

BACKGROUND: Lymphangitic streaking, characterized by linear erythema on the skin, is most commonly observed in the setting of bacterial infection. However, a number of nonbacterial causes can result in lymphangitic streaking. We sought to elucidate the nonbacterial causes of lymphangitic streaking that may mimic bacterial infection to broaden clinicians' differential diagnosis for patients presenting with lymphangitic streaking. METHODS: We performed a review of the literature, including all available reports pertaining to nonbacterial causes of lymphangitic streaking...

Cryptococcus gattii causes invasive fungal infections that have been increasing in incidence and global distribution in recent years. The major molecular genotypes of C. gattii that were previously classified as VGI to VGIV have recently been described as four new species: C. gattii (VGI), C. deuterogattii (VGII), C. bacillisporus (VGIII), and C. tetragattii (VGIV). The main driver for their classification has been phylogeny, and phenotypic diversity has not yet been extensively characterized. This study examines variation in attributes related to virulence and pathogenicity, including capsule thickness, cell size, tolerance to temperature, oxidative and osmotic stress, and cell wall integrity...

A 42-year-old man was admitted to our hospital with complaints of low back pain and intermittent right thigh pain. Twelve weeks before admission, the patient received intradiscal electrothermal therapy (IDET) at a local hospital. The patient still reported low back pain after the procedure that was managed with narcotic analgesics. Follow-up magnetic resonance imaging (MRI) was performed, and his referring physician thought the likely diagnosis was spondylodiscitis at the L4-5 spinal segment with a small epidural abscess...

Esophagitis dissecans superficialis (EDS) is a rare desquamative disorder of the esophagus. It is characterized by sheets of sloughed squamous tissue with normal underlying mucosa. We present a case of a 68-year-old man with severe anemia and a positive fecal occult blood test who was found to have features suggestive of EDS during endoscopy. However, histological features were suggestive of both EDS and fungal esophagitis. To our knowledge, this is the first reported case in literature which discusses the clinical scenario of fungal infection being a possible etiology rather than a commonly accepted differential diagnosis of EDS...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) continues to be a major public health problem worldwide. This is especially true in Northern Iran, which has high TB prevalence. The chronic nature of this disease is further exacerbated if it is accompanied by fungal infection, which usually remains undiagnosed and thus untreated. Thus, mycotic infections add fatal dimensions to pulmonary TB. Our objective was to determine the prevalence of invasive forms of fungal elements in sputum samples collected from patients with pulmonary TB at a reference laboratory in Ghaemshahr, Northern Iran, during the past 10years...

The occurrence of infections following allogeneic hematopoietic stem-cell transplant (HCT) is nearly universal. However, the relationship between infections and graft-versus-host disease (GVHD) is complex and attribution of infectious-related mortality is highly inconsistent, making comparison of infectious complication rates across allogeneic HCT clinical studies difficult. We categorized infectious complications from diagnosis or 1-year prior to HCT (whichever occurred later) through 2-years post-HCT according to timing, frequency, causative organism, severity, and contribution to mortality for 431 consecutive allogeneic HCT patients transplanted from 2008-2011...

We present the case report of a 19-year-old patient with chronic kidney disease due to chronic glomerulonephritis, in hemodialysis (HD) by central catheter, with the incidental finding of a mass of 28x16 mm in right atrium (RA). The diagnosis of thrombus, infective endocarditis or myxoma were considered. Given the context of immunosuppression and difficult access vascular therapeutic practice has proved complex. Although Doppler echocardiography suggested thrombus in RA, nuclear magnetic resonance imaging (MRI) indicated for the diagnosis of myxoma in RA...

Many countries have observed an increase in the incidence of invasive fungal infections (IFIs) over the past two decades with emergence of new risk factors and isolation of new fungal pathogens. Early diagnosis and appropriate antifungal treatment remain the cornerstones of successful outcomes. However, due to non-specific clinical presentations and limited availability of rapid diagnostic tests, in more than half of cases antifungal treatment is inappropriate. As a result, the emergence of antifungal resistance both in yeasts and mycelial fungi is becoming increasingly common...
