Objective: The clinical presentation, outcome, and risk factors for mortality in children with Fever of Unknown Origin (FUO) were determined. Methods: Medical records of pediatric patients admitted for FUO from January 2009 to December 2013 were reviewed. Clinical manifestations, physical exam findings, diagnostic work-ups and final diagnosis were determined, as well as the relationship between final diagnosis and risk for mortality. Results: Fifty-seven patients with FUO were included. Weight loss, cough, colds, and rashes were common symptoms while pallor, lymphadenopathies, and hepatomegaly were common physical exam findings. All patients underwent Phase I evaluation for FUO, while 73.7% underwent further diagnostic tests. A specific etiology was established in 96.5% of cases: infectious, 43.9%, connective tissue disease, 38.6%, and hematologic/oncologic, 14%. Two cases remained to have no specific diagnosis. Majority of patients had a benign course and were discharged improved (84.2%). The mortality rate is 15.8% and was not associated with any disease category (p-value 0.204). Conclusion FUO in children occurs across all age groups. Its clinical presentations are varied and non-specific and common signs and symptoms are pallor, lymphadenopathies, weight loss, cough, colds. and joints pains. Infection is the most common cause of FUO in children, followed by connective tissue diseases and hematologic and oncologic diseases. The mortality rate from FUO is 15.8%.
Fever of Unknown Origin

Aortic dissection most often presents with the severe chest pain and may have variable symptoms including fever. However, fever of unknown origin as the predominant manifestation of aortic dissection seems to be extremely rare. We report the case of a patient who sustained a prolonged spiking fever with unknown origin for 17 days following acute aortic dissection. The case serves as a reminder that prolonged fever may be the principal residual sequelae after aortic dissection.

Objective: To present a unique case of intravascular lymphoma of the inferior turbinate because of its rarity, unusual clinical presentation and difficulty in establishing a diagnosis. Design: Case Report Setting: A tertiary hospital Patient: A 66-year-old male admitted to the hospital due to intermittent high grade fever of six months duration. Result: The patient presented with fever of unknown origin, and exhaustive laboratory, ancillary procedures and biopsies to rule in/out infectious, autoimmune and oncologic causes were performed to arrive at a diagnosis. Nasal endoscopy revealed an enlarged, hypertrophied and violaceous right inferior turbinate with watery to mucoid discharge and septal deviation to the right confirmed by CT scans of the paranasal sinuses. Functional Endoscopic Sinus Surgery (FESS), septoplasty and turbinoplasty with biopsy revealed intravascular lymphoma. Chemotherapy was deferred due to the deteriorating medical condition and the patient expired seven months after the initial onset of symptoms. Conclusion: Patients who present with fever of unknown origin should undergo a thorough otorhinolaryngologic examination to exclude primary ENT conditions and ensure proper management. Given its rarity and multiplicity of presentation, it is extremely difficult to make a diagnosis of intravascular lymphoma. A high index of suspicion of intravascular lymphoma is necessary so that timely acquisition of tissue biopsy of any lesion involved will make a definite diagnosis. (Author)
LYMPHOMA FEVER FEVER OF UNKNOWN ORIGIN CASE REPORTS

Relapsing polychondritis is a rare autoimmune disease of unknown etiology with episodic but potentially progressive inflammatory manifestations. Auricular, articular and nasal manifestations are the most frequent disturbances. Fever is one of the manifestations of this disease but it rarely appears as an initial presentation. In this situation, the diagnosis is delayed until other manifestations are obvious. We report a case of relapsing polychondritis, which was presented as fever of unknown origin. Ten months after the onset of fever, auricular chondritis appeared and gave us the key to diagnosis.

Extra-nodal malignant lymphoma is often characterized by a lack of typical symptoms and positive results of auxiliary examinations, which make diagnosis difficult. In some cases, fever can be the only clinical manifestation. For the lymphoma patients presenting with persistent fever with a duration over 3 weeks, characteristics of fever including time of fever attack, fever type and effects of drugs may have significant value in the diagnosis, especially in the early stage of the disease or in rare cases.

Multiple chemical sensitivity/idiopathic environmental intolerance (MCS/IEI) is a commonly used diagnostic term for a group of symptoms. These symptoms have been described and commented on for more than 15 years in the USA. Recently, it has also been observed in Japan. The main features of this syndrome are multiple symptoms involving in multiple organ systems that are precipitated by a variety of chemical substances with relapses and exacerbation under certain conditions when exposed to very low levels which do not affect the population at large. There are no laboratory markers or specific investigative findings. Although traditional medical organizations have not agreed on a definition for this syndrome due to the lack of obvious evidence to demonstrate the existence of these symptoms, it is being increasingly recognized. It constitutes an increasing percentage of the caseload at occupational/environmental medical clinics. Part one of this review article discusses pathophysiological theories, substances which cause symptoms, prevalence in the general and specific populations, past history and family history, and clinical symptoms of MCS/IEI patients.

Multiple chemical sensitivity/idiopathic environmental intolerance (MCS/IEI) is a commonly used diagnostic term for a group of symptoms without apparent organic basis. The symptoms are characteristic of dysfunction in multiple organ systems. They wax and wane fluctuate according to exposure to low levels of chemical agents in the patient’s environment, and sometimes begin after a distinct environmental change or injury such an industrial accident or chemical introduced after remodeling. Although traditional medical organizations have not agreed on a definition for this syndrome, it is being increasingly recognized and makes up an increasing percentage of the caseload at occupational/environmental medical clinics. Part two of this review article discusses diagnosis, clinical examination, long-term follow up of MCS/IEI, and the role of physicians, research on odor and treatment, diseases with similar symptoms, and further research regarding MCS/IEI patients.
