Fever of unknown origin (FUO) is defined as fever over 7 to 10 days without a diagnosis despite a complete initial study. The most frequent causes are infections, autoimmune and tumors. Even though most cases are self-limited there is a minority that has an underlying etiology with an ominous forecast, encouraging a systematized study. OBJECTIVE: To report a rare case of a boy who presented fever of unknown origin associated to panniculitis and was diagnosed of subcutaneous panniculitis-like-T cell lymphoma and to emphasis the importance of a sequential study of FUO, in order to reach a diagnosis in patients who need a timely intervention...

Fever of unknown origin (FUO) is a rather rare clinical syndrome representing a major diagnostic challenge. The occurrence of more than three febrile attacks with fever-free intervals of variable duration during 6 months of observation has recently been proposed as a subcategory of FUO, Recurrent FUO (RFUO). A substantial number of patients with RFUO have auto-inflammatory genetic fevers, but many patients remain undiagnosed. We hypothesize that this undiagnosed subgroup may be comprised of, at least in part, a number of rare genetic febrile diseases such as Fabry disease...

RATIONALE: Adult-onset Still disease (AOSD) is a rare systemic inflammatory disease of unknown etiology characterized by evanescent salmon-pink rash, fever spikes, arthralgia, and lymphadenopathy. AOSD usually has a good prognosis, but it can sometimes be fatal, especially when it is complicated by systemic inflammatory response syndrome (SIRS) and multiple organ failure. PATIENT CONCERNS: A previously healthy 26-year-old woman was referred to our hospital for persistent high fever and mild systemic edema...

Kawasaki disease (KD) may be an acute systemic immune-mediated disease which occurs after infection of unknown KD pathogen(s). The aim of this study is to evaluate the changes in platelet count and immunoglobulin (Ig) levels (IgG, IgM, IgA, and IgE) during hospitalization.Forty-three patients with complete KD who received intravenous Ig at 2 g/kg were enrolled in South Korea. The platelet count and Ig levels of the patients were examined twice at presentation and around discharge (mean 6.2 ± 2.4 days apart) and the relationships between platelet level and Ig levels were evaluated...

Serotonin (5-HT) is a neuromodulator involved in several central-mediated mechanisms, such as endocrine processes, behavior, and sleep. Dysfunction of the serotonergic system is mainly linked to psychiatric disorders, but emerging evidence suggests that immune system activation may also alter brain 5-HT signaling. However, whether central 5-HT modulates systemic inflammation (SI) remains unknown. For this purpose, male Wistar rats (280-350 g, 8-9 weeks) were submitted to the experimental protocols beginning between 9 and 10 AM with the performance of injections...

Etiology of acute undifferentiated febrile syndrome (AUFS) is often unknown, leading to inaccurate diagnosis and treatment. Villeta town has been identified as an endemic area for spotted fever group (SFG) rickettsioses but little is known about possible amplifier hosts and other Rickettsia species different from Rickettsia rickettsii. Besides, few studies have approached other AUFS etiologies in the region. We investigated the role of dengue, leptospirosis, rickettsioses, human anaplasmosis, and Q fever as possible causes of AUFS in patients from Villeta...

INTRODUCTION: Adult-onset Still disease (AOSD) is a rare systemic inflammatory disease of unknown cause. Its symptoms usually include persistent fever, fugitive salmon-colored rash, arthritis, sore throat (not specific), but it may also lead to internal organs' involvement, which presents with enlargement of the liver and spleen, swollen lymph nodes, carditis or pleuritis - potentially life-threatening complications. In rare cases, AOSD can cause aseptic meningitis or/and encephalitis...

Background: Large spatial heterogeneity was observed in the dengue fever outbreak in Guangzhou in 2014, however, the underlying reasons remain unknown. We examined whether socio-ecological factors affected the spatial distribution and their interactive effects. Methods: Moran's I was applied to first examine the spatial cluster of dengue fever in Guangzhou. Nine socio-ecological factors were chosen to represent the urbanization level, economy, accessibility, environment, and the weather of the 167 townships/streets in Guangzhou, and then the geographical detector was applied to analyze the individual and interactive effects of these factors on the dengue outbreak...

INTRODUCTION: Antibiotics represent one of the most widely prescribed therapeutic agents in children. It has been estimated that 30-50% of antibiotic prescriptions for this population are inappropriate. In this scenario, analysis of prescription data provides an invaluable source of information as a basis for implementing strategies for improvement in this field. OBJECTIVE: To assess the appropriateness of antibiotic prescriptions in a paediatric population at an emergency department...

The Flavivirus genus contains some of the most prevalent vector-borne viruses, such as the dengue, Zika and yellow fever viruses that cause devastating diseases in humans. However, the insect-specific clade of flaviviruses is restricted to mosquito hosts, albeit they have retained the general features of the genus, such as genome structure and replication. The interactions between insect-specific flaviviruses (ISFs) and their mosquito hosts are largely unknown. Pathogenic flaviviruses are known to modulate host-derived microRNAs (miRNAs), a class of non-coding RNAs that are important in controlling gene expression...

Chronic nonbacterial osteomyelitis (CNO) is a bone disease with nonbacteria osteitis of unknown etiology. Symptoms, including pain, swelling, fever, etc, always result in misdiagnosis and wrong therapy. This study aims to introduce the clinical features and the therapy of patients with CNO accompanied with mucocutaneous disease. The authors retrospectively reviewed the patients who presented to our hospital from 2000 to 2016, the final sample including 3 patients with CNO accompanied with mucocutaneous disease, who presented repeated severe pain of bone, swelling, tenderness, and fever during attack stage with no evidence of bacterial infections...

A combination of unexplained peripheral neuropathy, hypoparathyroidism, and the inability to cope with metabolic stress could point to a rare inborn error of metabolism, such as mitochondrial trifunctional protein (MTP) deficiency.Here, we describe a 20-year-old woman who was known since childhood with axonal motor sensory polyneuropathy of unknown origin. She presented with progressive dyspnoea, and increased muscle weakness, preceded by 6 days of fever, vomiting, and diarrhoea. Laboratory testing showed rhabdomyolysis, and hypocalcaemia with low parathyroid levels...

Background: Dengue can cause increased vascular permeability that may lead to hypovolemic shock. Endothelial dysfunction may underlie this; however the association of endothelial nitric oxide pathways with disease severity is unknown. Methods: We performed a prospective observational study in two Vietnamese hospitals, assessing patients presenting early (<72 hours fever) and patients hospitalized with warning signs or severe dengue. The reactive hyperaemic index (RHI), which measures endothelium-dependent vasodilation and is a surrogate marker of endothelial function and NO bioavailability was evaluated using peripheral artery tonometry (EndoPAT) and plasma levels of L-arginine, Arginase-1 and ADMA were measured at serial time-points...

Fever is the most leading symptom of autoinflammatory diseases (AID). Therefore, AID have to be considered in differential diagnosis concerning fever of unknown origin. Unspecific Inflammatory manifestations may lead to misinterpretations that possibly cause irreversible organ damage. Effective treatment options are available and imply profound diagnostics.

Fever of unexplained (or unknown) origin (FUO) remains a relevant clinical problem even with modern diagnostic methods. In addition to the classical definition, new categories of FUO describe different clinical situations: nosocomial FUO, FUO in neutropenic/immundeficient patients and FUO in patients with HIV-infection. The new categories are defined by much shorter duration of fever, i. e. mostly three days. Each category of FUO shows a different spectrum of infectious diseases. Often, subacute bacterial endocarditis is very difficult to verify...

BACKGROUND: Previous studies have found increased rates of musculoskeletal problems in adults with allergic disease, but whether this association holds true for children is unknown. OBJECTIVE: To investigate the association of bone, joint, and muscle problems in children with a history of allergic disease. METHODS: Data were obtained from the 2007 Child and Adolescent Health Measurement Initiative. Univariable and multivariable logistic regression models accounting for the sampling design were used to evaluate associations of bone, joint, and muscle problems with allergic diseases, such as asthma, hay fever, food allergies, and eczema...
