Article Comprehensive Proteomic and Metabolomic Analysis of Novel Substituted Fluoroquinolone Derivatives in Escherichia Coli Isolates(John Wiley and Sons Ltd, 2026) Nigiz Ş.; Kulabaş N.; Türe A.; Kablan S.; Koçak E.; Özkul C.; Küçükgüzel İ.; Koçak, Engin; Nigiz, Şeyma; Kablan, Sevilay Erdoğan; Özkul, Ceren; Kulabaş, Necla; Küçükgüzel, İlkay; Türe, AslıAntimicrobial resistance is one of the most important global problems, and new antibiotic requirements have been emerging as a key point in this issue. In the present work, we focused on the efficiency of two novel promising fluoroquinolone derivatives on resistant Escherichia coli isolates at the molecular level. Their mode of action and adaptation process were evaluated by using proteomics and metabolomics analysis. Proteomics analysis showed that two compounds have an effect mainly on the ribosomal process and energy metabolism. Moreover, we observed compounds that affect various important antimicrobial targets, such as ribosomal subunits, phosphotransacetylase, and chaperone proteins. In metabolomics analysis, we found that compounds altered bacterial metabolism directly. Pathway analysis showed that cofactor biosynthesis and energy metabolism were affected mainly by undertreated groups. Our experiments demonstrated that novel fluoroquinolone derivatives have promising results at the molecular level and results will contribute to further studies. © 2026 John Wiley & Sons Ltd.Article Ludwig's Angina in a 6-Year Child: Case Report(Wiley, 2025) Akbari, Negarin; Razavi, Ali; Sabzi, Zahra; Parhiz, JabbarLudwig's angina is a rare but potentially fatal cellulitis that affects the submandibular, sublingual, and submental spaces, typically triggered by dental infections. This case report details a severe presentation of Ludwig's angina in a 6-year-old girl who presented with submandibular swelling, fever, voice alterations, and respiratory distress. Diagnosis was based on clinical evaluation, supported by CT imaging, revealing significant airway narrowing and lymphadenopathy. The patient was promptly intubated to secure the airway, followed by emergency surgical drainage and intravenous antibiotics. Postoperative care included sedation, ongoing monitoring in the PICU, and close follow-up by multiple specialties. After a 10-day hospitalization, the patient showed significant recovery with no complications. The case underscores the importance of early diagnosis and intervention in preventing severe complications such as airway obstruction, sepsis, and mediastinal spread. It highlights the critical role of interdisciplinary collaboration, including pediatric infectious disease specialists, surgeons, and anesthesiologists, in managing this life-threatening condition effectively.Article Post-Covid Neutropenia in an Infant With Thalassemia Minor: Case Report(Wiley, 2025) Elsherif, Yasmine; Elsherif, Omar; Karimi, Mehran; Ibrahim, Ismail A.; Abukhadijah, Hana J.This case of an 11-month-old female who developed severe neutropenia following COVID-19 infection underscores the need for heightened vigilance and monitoring of hematological parameters in infants post-COVID-19. The exact mechanism of COVID-19-induced neutropenia is not fully understood, but it may involve cytokine-induced suppression of hematopoiesis and bone marrow repression due to the inflammatory response. Given the potential for serious clinical implications, including increased susceptibility to infections, it is crucial to effectively identify and manage neutropenia in this vulnerable population. Further research is necessary to elucidate the underlying mechanisms and optimize treatment strategies for COVID-19-related hematological complications in infants.Article A Guide To Facilitate the Creation of a Femoral Tunnel for Arthroscopic Ligamentum Teres Reconstruction: a Three-Dimensional Computed Tomography Study(Oxford Univ Press, 2024) Ismailoglu, Abdul Veli; Ismailoglu, Pelin; Zeynalov, Samir, I; Ozdogmus, Omer; Yildizhan, Saliha Elif; Bayramoglu, Alp; Kayaalp, AsimThe ideal femoral tunnel passing through the centre of the femoral neck targeted to the footprint of the ligamentum teres (LT) is established during the LT reconstruction surgery with the free-hand technique. We aimed to quantitatively determine the entry site and define the angular orientation of the ideal femoral tunnel with its relevance to the femoral valgus angle (FVA) and the femoral anteversion angle (FAA) to facilitate the creation of an ideal femoral tunnel during the LT reconstruction surgery. A total of 60 randomly selected CT images were obtained to reconstruct three-dimensional femur models. A virtual reamer representing the ideal femoral tunnel was placed in the femur models. The femur length, FVA, FAA, the femoral tunnel anterior angle, the femoral tunnel superior angle and the skin- and bony-entry sites were measured. The femoral tunnel angular orientation was strongly correlated with the FVA and the FAA. Mathematical formulas were defined by which entry site of the reamer and the anterior and superior angulation of the femoral tunnel could be estimated before the surgery. The mean skin-entry site was 67.3 mm distal and 0.1 mm anterior to the centre of the greater trochanter's superior border. The angular orientation of the femoral tunnel using FVA and FAA can be easily estimated using mathematical formulas before LT reconstruction surgery. The entry site and angular orientation of the femoral tunnel described in this study can be used to reduce dependency on the usage of fluoroscopy and the workload on the surgeon during the LT reconstruction surgery.Article Tinea Capitis (favus) in a 8-Year Child: Case Report(Wiley, 2024) Akbari, Negarin; Parhiz, Jabbar; Sabzi, ZahraKey Clinical MessageIn examining any scalp itch or skin lesions, especially in children with long hair, fungal lesions under the hair may not be diagnosed in a timely manner. Additionally, fungal infection of the scalp, known as tinea capitis, is considered a chronic condition and if left untreated, it can lead to alopecia (hair loss) and permanent scarring.AbstractTinea capitis (TC) is a common cutaneous fungal infection in childhood. In this report, we describe the case of an 8-year-old child presenting with erythematous scalp lesions accompanied by hair loss. Upon examination, palpation revealed a swollen and tender left parotid gland. Notably, the frontal region of the scalp exhibited erythematous lesions and scaly red plaques resembling yellowish paste-like dough. Subsequent clinical evaluation and culture analysis confirmed the diagnosis of TC. The patient received treatment with Terbinafine 125 mg for a duration of 8 weeks. Follow-up examinations conducted after 3 months showed no signs of recurrence. Accurate diagnosis and timely treatment, along with adherence to medication regimens, are crucial in cases of TC, and differential diagnoses should be considered. Treatment should commence promptly upon diagnosis to prevent complications such as scalp baldness and transmission to others. This case report underscores the significance of establishing a precise diagnosis and effective treatment for this dermatophytosis to mitigate the risk of recurrences or therapeutic shortcomings, particularly in infants.Article Citation - WoS: 1The Unlikely Combination: Anderson-Fabry Disease and Congenital Dyserythropoietic Anemia Type Ii in a Pediatric Patient(Wiley, 2024) Elsherif, Yasmine; Ibrahim, Ismail A.; Elsherif, Omar; Abukhadijah, Hana J.Anderson- Fabry disease (AFD) is a rare condition, characterized by a lysosomal storage disorder affecting lipid storage. It manifests in two forms: classic (early- onset) and nonclassic (late- onset). Conversely, congenital dyserythropoietic anemia (CDA) is a rare blood disorder caused by ineffective erythropoiesis, which results in the production of abnormal erythroblasts during the maturation of red blood cells, with CDA type II being the most frequent type. Both disorders have well- understood pathophysiologies, yet they are genetically distinct. AFD is inherited in an X- linked manner, whereas CDA type II follows an autosomal recessive pattern of inheritance. Although both AFD and CDA type II have been reported separately in the literature. The co- existence for both AFD and CDA type II has not been reported. We describe a 10- year- old boy, with both which is believed to be the first documented case.
