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%.

Visualization of the tissue loss tangent property can provide distinct contrast and offer new information related to tissue electrical properties. A method for non-invasive imaging of the electrical loss tangent of tissue using magnetic resonance imaging (MRI) was demonstrated, and the effect of loss tangent was observed through simulations assuming a hyperthermia procedure. For measurement of tissue loss tangent, radiofrequency field maps (B1+ complex map) were acquired using a double-angle actual flip angle imaging MRI sequence. The conductivity and permittivity were estimated from the complex valued B1+ map using Helmholtz equations. Phantom and ex-vivo experiments were then performed. Electromagnetic simulations of hyperthermia were carried out for observation of temperature elevation with respect to loss tangent. Non-invasive imaging of tissue loss tangent via complex valued B1+ mapping using MRI was successfully conducted. Simulation results indicated that loss tangent is a dominant factor in temperature elevation in the high frequency range during hyperthermia. Knowledge of the tissue loss tangent value can be a useful marker for thermotherapy applications.

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

Fever (body temperature above 38℃) is relatively common during the first few days after general anesthesia. Postoperative fever is usually caused by the inflammation induced by surgery and resolves spontaneously; however, it can be a manifestation of a serious complication such as malignant hyperthermia. We report a case of postoperative hyperthermia (body temperature > 40℃) that was refractory to conventional anti-pyretic measures and finally resolved with dantrolene administration.

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.

The authors experienced a case of myoglobinuria accompanied by generalized myalgia and mild fever that developed 3 hours 30 minutes after general anesthesia. Tracheal intubation was done smoothly 5 minutes after injection of thiopental sodium(275 mg) and pancuronium bromide(6 mg), and anesthesia was maintained with ethrane/N2O/O2(1.5-2%/21/21/min). There was no specific event except tachycardia and fluctuation of blood pressure throughout operation. In this case, we assume that the myoglobinuria is a presentation of the sign of an abortive type of malignant hyperthermia. However, it was not confirmed. We had good patient outeome with the supportive measures of hydration and diuresis. The patient was discharged twenty three days after operation without any complication.
