Background: Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease caused by the polyomavirus JC (JCV) affecting subjects with impaired immune system. While JCV-DNA detection in cerebrospinal fluid (CSF) is diagnostic of PML, the clinical significance of plasma JCV-DNA is still uncertain. Methods: We retrospectively analyzed plasma samples drawn from patients with PML close to disease onset, and controls without PML. In PML patients, we compared plasma JCV DNA detection and levels to: JCV DNA in the other biological samples, clinical and laboratory parameters and patients' survival...

Prognostic genomic biomarkers that can be measured at diagnosis to aid choice of treatment options are unavailable for most common cancers. This is due in part to the poor quality and quantity of available diagnostic specimens for discovery research and to limitations in genomic technologies. Recent technical advances now enable high-density molecular analyses using suboptimal biological specimens. Here we describe the optimization of a transcriptome-specific protocol for use with formalin-fixed, paraffin-embedded (FFPE) diagnostic prostate cancer (PrCa) specimens...

INTRODUCTION: Surgery is an essential component of a functional health system, with surgical conditions accounting for nearly 11-15% of world disability. While communicable diseases continue to burden low- and low-middle-income countries, non-communicable diseases, such as cancer, are an important cause of morbidity and mortality worldwide. Preliminary data on malignancies in low- and middle-income countries, specifically in Africa, suggest a higher mortality compared to other regions of the world, a difference partially explained by limited availability of screening and early detection systems as well as poorer access to treatment...

Infectious spleen and kidney necrosis virus (ISKNV) has been recognized as the causative agent of the most serious disease in cultured mandarin fish, Siniperca chuatsi, in China. Disease outbreaks have resulted in substantial losses to the aquaculture industry. Currently, reliable laboratory detection and identification methods are available for this virus. However, rapid detection methods applicable for on-site diagnosis of this infectious agent are unavailable. To address this need, a nearly instrument-free, cost-effective and simple detection method was developed and optimized and incorporates cross priming amplification coupled with vertical flow visualization for rapid identification of ISKNV (ISKNV-CPA-VF)...

Otitis media with effusion (OME) is an important and common condition affecting hearing in pediatric patients characterized by the presence of fluid in the middle ear space. The fluid is normally described as serous or mucoid based on differences in the fluid viscosity. The differential diagnosis of two OMEs namely serous and mucoid is of significant clinical value because while the former is self-limiting, surgical procedure is commonly required for the latter. However, accurate identification of fluid types remains a challenging target unattainable with current clinical modalities due to unavailability of non-perturbative molecular tools...

Gastrointestinal (GI) endoscopy plays an indispensable role in the diagnosis and management of various pediatric GI disorders. While the pace of development of pediatric GI endoscopy has increased over the years, it remains sluggish compared to the advancements in GI endoscopic interventions available in adults. The predominant reasons that explain this observation include lack of formal training courses in advanced pediatric GI interventions, economic constraints in establishing a pediatric endoscopy unit, and unavailability of pediatric-specific devices and accessories...

Diagnosing and managing drug hypersensitivity is challenging because there are no clear limits between different types of drug reactions. Distinguishing between type A (predictable) and type B (hypersensitivity) reactions when a drug is introduced on the market is not easy. When many people use a drug, adverse reactions can occur, conditioned by diverse genetic profiles, viral infections or concomitant therapy. Occasionally the only tool clinicians have on which to base the diagnosis is the clinical history...

Today, 80% of children and adolescents with cancer survive their disease. From the results of aftercare research arises the question: Are the survivors also healthy? Many late effects depend on the type of cancer and its treatment. Patients with brain tumors and with malignant sarcomas are very often affected by secondary diseases. Data from the USA report that around 2/3 of all patients still living 30 years after their cancer treatment in childhood suffer from late complications. Equivalent figures for Germany were previously unavailable...

Calcitonin (CT), a tumor marker for medullary thyroid cancer (MTC), can be stimulated with pentagastrin or calcium. Because of the unavailability of pentagastrin, basal CT measurement is frequently used for the preoperative diagnosis of MTC. The aim of the study was to define basal serum calcitonin (bCT) cut-off thresholds for diagnosing MTC. Within a retrospective analysis, 114 patients (51 males) were included fulfilling the criteria of an increased preoperative bCT level (>10 pg/ml) and the criteria of an available postoperative histology analysis...

Sickle cell anemia (SCA) is the commonest severe monogenic disorders of humans. The disease has been highly characterized in high-income countries but not in sub-Saharan Africa where SCA is most prevalent. We conducted a retrospective cohort study of all children 0-13 years admitted from within a defined study area to Kilifi County Hospital in Kenya over a five-year period. Children were genotyped for SCA retrospectively and incidence rates calculated with reference to population data. Overall, 576 of 18,873 (3...

Prostatic involvement is common in men with melioidosis. Indeed, some clinicians recommend radiological screening of all male patients as an undrained prostatic abscess may result in relapse of this potentially fatal disease. However, sophisticated medical imaging is frequently unavailable in the remote and resource-poor locations where patients are managed. In this retrospective study from Queensland, Australia, 22/144 (15%) men with melioidosis had a radiologically confirmed prostatic abscess. The absence of urinary symptoms had a negative predictive value (NPV) (95% confidence interval [CI]) for prostatic abscess of 96% (90-99%), whereas a urinary leukocyte count of < 50 × 10(6)/L had an NPV (95% CI) of 100% (94-100%)...

Recent World Health Organization (WHO) guidelines recommend antiretroviral therapy (ART) for all HIV-infected people; previously CD4+ T lymphocyte quantification (CD4 count) or clinical staging determined eligibility for children ≥ 5 years old in low- and middle-income countries. We examined positive predictive value (PPV) of a rapid diagnostic test (RDT) algorithm and ART eligibility for hospitalized children with newly diagnosed HIV infection. We enrolled 363 hospitalized Malawian children age 2 months to 16 years with two serial positive HIV RDT from 2013 to 2015...
