RESUMO
Neurobrucellosis is rare in children, presenting with a variety of clinical manifestations, including meningitis, meningoencephalitis, cranial neuropathies, and intracranial mass-like lesions. We present a case of a 17-year-old girl admitted to the hospital in Istanbul for headache. Lumbar puncture showed elevated intracranial pressure, monocytic pleocytosis, elevated total protein, and hypoglycorrhachia. Brucella melitensis grew from the cerebrospinal fluid. The patient was treated with doxycycline, rifampin, amikacin, and ceftriaxone and showed persistent sensorineural hearing loss. It is essential to consider brucellosis in the differential diagnosis of infectious neurological disease in areas where the disease is endemic. Serologic tests and cultures are needed for diagnosis, and efforts need to be made to identify the infecting organism to the species level to guide zoonotic source control efforts.
RESUMO
BACKGROUND: Purpura fulminans (PF) is a rare, life-threatening condition involving consumptive coagulopathy and intravascular thrombosis, causing purpura and necrosis in the skin and soft tissue. CASE REPORT: A 4-year-old Tajik girl with PF secondary to varicella-zoster virus (VZV) infection presented with purplish red, diffuse, painful lesions localized to the entire right leg. Her vaccination status was unknown, and she did not have concurrent chronic illness. Ten days before admission, the girl was admitted to another hospital in Tajikistan with a diagnosis of chickenpox and PF. She was then transferred to the hospital of the authors of the current report due to the enlargement of lesions to the gluteal region, a change in the color of lesions from red to black, and the detection of arterial thrombosis via Doppler ultrasonography. Multiple surgical debridements were performed to manage tissue necrosis, and the patient's right leg was amputated at the 18th week of admission. The patient was discharged after 26 weeks of hospitalization. CONCLUSION: Although VZV infections mostly cause mild and self-limiting eruptive disease, they can progress, with life-threatening complications, including PF. To prevent VZV infection and resulting complications, immunization with live attenuated vaccines and maintaining population immunity above a certain threshold are the most important strategies to prevent the circulation of the virus.

BACKGROUND: Fosfomycin is gaining increasing attention for its activity against MDR or XDR pathogens. Currently, IV fosfomycin is a potential option for treating various infections, including urinary tract infections, pneumonia and skin infections when first-line treatments fail. OBJECTIVES: To evaluate the demographic, clinical, microbiological and treatment modality of children received IV fosfomycin to treat infections caused by MDR pathogens since there are few data on the use of fosfomycin in children. METHODS: This study was conducted retrospectively with patients under 18 years of age who were treated with IV fosfomycin for at least 72 h due to infections caused by MDR pathogens between January 2019 and October 2023 at Marmara University Pendik Training and Research Hospital, Istanbul, Türkiye. Data on demographic and clinical features, microbiological findings, treatment modalities and side effects were evaluated. RESULTS: Twenty-five children, for a total of 32 cases of infection episodes, with a mean age of 11.4â±â3.92 years who received IV fosfomycin were included. The most frequent comorbidity was chronic pulmonary diseases, and the most common infection needed for IV fosfomycin was MDR Pseudomonas aeruginosa pneumonia. In all cases, fosfomycin was administered in combination with other antibiotics, mainly meropenem-colistin (68.7%) or meropenem (15.6%). Twenty-two (71.9%) cases had favourable clinical responses at the end of therapy. CONCLUSIONS: Our results suggest that IV fosfomycin may be an effective treatment option for MDR pathogens in the paediatric population. Nevertheless, careful stewardship is necessary to maintain efficacy and reduce antimicrobial resistance selection risk.
RESUMO
INTRODUCTION: Central nervous system (CNS) aspergillosis is an opportunistic infection with an increasing incidence and a high mortality rate. It is seen in immunocompromised patients as well as in immunocompetent patients. Here, we present disseminated aspergillosis in a child with nephrotic syndrome treated with long-term and aggressive systemic antifungal treatment and intraventricular (IVent) liposomal amphotericin B (L-AmB) as well as surgical excision and drainage due to difficulty in management. CASE REPORT: A 10-year-old boy with nephrotic syndrome on steroid therapy was admitted with limping and weakness. The cranial magnetic resonance imaging showed multiple intraparenchymal scattered abscesses. The largest one was excised and drained. Abscess culture revealed Aspergillus fumigatus and histopathological examination revealed septate hyphae compatible with Aspergillosis. Intravenous (IV) voriconazole was started, and IV L-AmB was added. The size of lesions and perilesional edema continued to increase, and then IVent L-AmB was added. With IVent and systemic antifungal treatment, regression of the lesions was observed. He was followed up with oral voriconazole and weekly IVent L-AmB. After 2 and a half months, he was re-operated because of increased lesion size, number and perilesional edema, and IV voriconazole and other salvage antifungal therapies were started. Since the lesions had decreased and remained stable, IV voriconazole was switched to oral therapy, and he was followed up as an outpatient. Immunodeficiency diseases were excluded by immunological and genetic tests. CONCLUSION: Management of central nervous system aspergillosis can be challenging despite long-term and aggressive systemic and IVent antifungal treatment as well as surgical excision and drainage.
RESUMO
Echinococcosis is the most common cestode infection globally caused by the Echinococcus species. The most common organ involvement is the lungs and liver, but other organs can be rarely involved. Here, we present a case with a giant cerebral hydatid cyst. A 4-year-old boy presented with abnormal gait and walking at Marmara University School of Medicine Pendik Training and Research Hospital, Istanbul, Türkiye in September 2022. Cranial magnetic resonance imaging showed a cyst of 13 cm in diameter. The cyst was enucleated successfully with no rupture. Oral albendazole therapy was started. There was no eosinophilia, and the echinococcal indirect hemagglutination test was negative. Ultrasonography detected an anechoic cystic lesion in the liver. He was evaluated for deep-organ involvement; however, no cysts were detected in other organs. The histopathological examination was compatible with a hydatid cyst. Although intracranial hydatid disease in children is rare, it should be considered among the differential diagnoses in patients with neurological symptoms, especially in endemic regions.
RESUMO
OBJECTIVES: Septic arthritis (SA) is a serious bacterial infection that must be treated efficiently and timely. The large number of culture-negative cases makes local epidemiological data important. Accordingly, this study aimed to evaluate the etiology, clinical characteristics, and therapeutic approach of SA in children in Turkiye, emphasizing the role of real-time polymerase chain reaction (PCR) techniques in the diagnosis. METHODS: In this multi-center, prospective study, children hospitalized due to SA between February 2018 and July 2020 in 23 hospitals in 14 cities in Turkiye were included. Clinical, demographic, laboratory, and radiological findings were assessed, and real-time PCR was performed using synovial fluid samples. RESULTS: Seventy-five children aged between 3 and 204 months diagnosed with acute SA were enrolled. Joint pain was the main complaint at admission, and the most commonly involved joints were the knees in 58 patients (77.4%). The combination of synovial fluid culture and real-time PCR detected causative bacteria in 33 patients (44%). In 14 (18.7%) patients, the etiological agent was demonstrated using only PCR. The most commonly isolated etiologic agent was Staphylococcus aureus, which was detected in 22 (29.3%) patients, while Streptococcus pyogenes was found in 4 (5.3%) patients and Kingella kingae in 3 (4%) patients. Streptococcus pyogenes and Kingella kingae were detected using only PCR. Most patients (81.3%) received combination therapy with multiple agents, and the most commonly used combination was glycopeptides plus third-generation cephalosporin. CONCLUSIONS: Staphylococcus aureus is the main pathogen in pediatric SA, and with the use of advanced diagnostic approaches, such as real-time PCR, the chance of diagnosis increases, especially in cases due to Kingella kingae and Streptococcus pyogenes.
