Urinary tract infection (UTI) is the most prevalent urological condition worldwide. Choosing appropriate antibiotics for patients who have fever before receiving a culture result is challenging. This retrospective study enrolled patients 394 patients hospitalized at Gangneung Asan Hospital for UTI from May 2017 to April 2021. Fever at 48 h of hospitalization was the analysis point, as this is when the response to antibiotic therapy manifest, although the results of antibiogram are not available. Multivariate analysis was performed to assess the correlation between ESBL producing bacteria (EPB) and fever at 48 h. Overall, 36.3% of patients had EPB and 27.9% had fever at 48 h. In multivariate analysis, a significant positive association was found between EPB and fever (odds ratio 1.17, 95% CI 1.05-1.30, P = 0.004) Female had negative association with multivariate model (OR 0.83, 95% CI 0.73-0.94, P = 0.004). Diabetes did not demonstrate a significant association with EPB. (OR 1.10, 95% CI 0.99-1.22, P = 0.072). Fever at 48 h is associated with EPB and could be considered a predictive factor for EPB infection in patients with UTI. Antibiotic escalation may be considered in patients with fever at 48 h.

Fever of unknown origin in adolescents is a challenging disease state for which potential underlying etiology can include infectious, non-infectious inflammatory, and malignancy processes. Careful and thorough history (including exposure history), serial examination, and targeted laboratory and imaging testing is critical for these patients. In adolescents in which an etiology is discovered, infectious etiology remains the most prevalent, followed by non-infectious inflammatory diseases. In patients with non-diagnostic overall reassuring work up, the prognosis is typically self-limiting and favorable.

UNASSIGNED: Dengue fever is a mosquito-borne infectious disease endemic in over 100 countries around the world. Among the complications that dengue can cause the Hemophagocytic Lymphohistiocytosis is one of great concern for its severity and complex diagnosis.
UNASSIGNED: Hereby we document a case of this disease expressed on a previously healthy 6-year-old female patient whose dengue infection was so severe that needed intensive care management with vasoactive drugs and diuretics. After a short period of wellness began newly with fever, pancytopenia, hepatitis, and inflammatory response symptoms.
UNASSIGNED: A Dengue associated Hemophagocytic Lymphohistiocytosis syndrome was suspected and treated with intravenous corticosteroids on a 3-day scheme at no signs of malignancy with excellent response. The health care professionals must know about this not novel entity in order to reach an efficient diagnosis and treatment mostly, but not only, those in tropical and sub-tropical regions of the word were dengue virus is endemic.
UNASSIGNED: La fiebre por dengue es una enfermedad infecciosa transmitida por mosquitos, endémica en más de 100 países alrededor del mundo. La Linfohistiocitosis Hemofagocítica, dentro de las complicaciones que puede ocasionar el dengue, es una de las más preocupantes por su complejidad diagnostica y gravedad.
UNASSIGNED: Femenino de 6 años de edad, previamente sana, cuya infección por dengue fue tan grave que requirió manejo en cuidados intensivos. Después de un breve período de bienestar recrudeció la fiebre, además de pancitopenia, hepatitis y síntomas de respuesta inflamatoria.
UNASSIGNED: Se sospechó síndrome de Linfohistiocitosis Hemofagocítica asociada a Dengue y se trató con corticoides intravenosos en un esquema de 3 días con excelente respuesta. Los profesionales de la salud deben conocer esta entidad no novedosa para poder llegar a un diagnóstico y tratamiento eficaz en su mayoría, pero no solo, en las regiones tropicales y subtropicales del mundo donde el virus del dengue es endémico.

A prolonged fever in a child can be due to a range of causes including infectious, autoimmune, malignant, or genetic in etiology. In our report, we present the case of a previously healthy three-year-old female diagnosed with macrophage activation syndrome (MAS) due to complications of systemic juvenile arthritis (sJIA). MAS is considered a secondary subtype of hemophagocytic lymphohistiocytosis (HLH), a rare and life-threatening group of syndromes characterized by overstimulation of the immune system leading to systemic inflammation. Through our case, we wanted to bring awareness to this uncommon group of diseases as well as discuss the importance of differentiating between its subtypes. While HLH and MAS have similar clinical presentations, the treatment regimen for each is distinct. Moreover, further research should be conducted to create standardized criteria and treatment guidelines that are evidence-based in order to properly manage these patients.

Kikuchi disease (KD) is a benign self-limiting rare disease with unknown etiology. Prolonged fever with tender neck lymphadenitis is the most common presentation. Blood tests are not specific, and the final diagnosis is by biopsy. We describe two patients, ages seven and twelve years, who presented with fever and neck lymphadenitis. Both cases received antibiotics for more than two weeks without improvement. Blood work showed high inflammatory markers. The manifestation of the second case overlapped with Hashimoto\'s disease. The later diagnosis was confirmed by lymph node (LN) biopsy.

BACKGROUND: Kawasaki disease is an acute febrile condition in children. It affects mainly children under 5 years old, and is known to cause coronary artery abnormalities if treatment is delayed. The diagnosis rests mainly on clinical criteria. However, it is also known that some infants do not have diagnostic criteria sufficient enough for the diagnosis of Kawasaki disease. Further, children may rarely present with unusual features, and this entity is recognized as \"Atypical Kawasaki disease.\"
METHODS: We present the case of a 9-month-old Tamil boy who presented with sterile gross hematuria in association with prolonged fever, lymphadenopathy, and generalized maculopapular rash. He had high inflammatory markers and echocardiogram disclosed left coronary artery dilatation. The diagnosis of incomplete Kawasaki disease was confirmed based on clinical grounds supported by investigations and exclusion of differential diagnosis. The child showed a good response to intravenous immunoglobulin and aspirin.
CONCLUSIONS: Kawasaki disease is one of the important differential diagnoses of protracted fever of unknown origin in very young children. Since delayed treatment is associated with a high risk of complications, atypical Kawasaki disease needs to be suspected in children presenting with unusual features such as macroscopic hematuria that occurs in association with unexplained prolonged fever.

Kawasaki disease (KD) is the leading cause of acquired heart disease. The cardiac clinical features seen with KD require diagnosis and treatment within 10 days of symptoms to decrease the risk of complications. This case report examines the complexity of prolonged fever in a pediatric patient with a positive test for severe acute respiratory coronavirus 2 and meets the KD criteria.
