    Post-Meningitic Syndrome: Pathophysiology and Consequences of Streptococcal Infections on the Central Nervous System.
    (2024-10-15) Kaddoura, Rachid; Abdalbari, Karim; Badla, Beshr Abdulaziz; Hijleh, Amin Abu; Hanifa, Mohamed; AlAshkar, Masa; Asbaita, Mohamed; Othman, Deema; Faraji, Hanan; AlBakri, Orjwan; Tahlak, Sara; Hijleh, Amir Abu; Kabbani, Raneem; Resen, Murtadha; Du Plessis, Stefan S; Omolaoye, Temidayo S
    Streptococcus species represent a significant global cause of meningitis, leading to brain damage through bacterial virulence factors and the host inflammatory response. Upon entering the central nervous system (CNS), excessive inflammation leads to various neurological and psychological complications. This review explores the pathophysiological mechanisms and associated outcomes of streptococcal meningitis, particularly its short- and long-term neurological sequelae. Neurological symptoms, such as cognitive impairment, motor deficits, and sensory loss, are shown to vary in severity, with children being particularly susceptible to lasting complications. Among survivors, hearing loss, cognitive decline, and cranial nerve palsies emerge as the most frequently reported complications. The findings highlight the need for timely intervention, including neurorehabilitation strategies that focus on optimizing recovery and mitigating long-term disabilities. Future recommendations emphasize improving early diagnosis, expanding vaccine access, and personalizing rehabilitation protocols to enhance patient outcomes. As a novel contribution, this review proposes the term "post-meningitic syndrome" to showcase the broad spectrum of CNS complications that persist following streptococcal meningitis, providing a framework for a future clinical and research focus.

    A Rare Case of Sarcoidosis Presenting as an Isolated Breast Mass and Pain: A Case Report and Literature Review
    (2023) Kaddoura, Rachid; Al Haj, Maitha; Faraji, Hanan; Abdalbari, Karim
    Abstract: Objective: Rare disease Background: Sarcoidosis is a benign systemic granulomatous disorder of unknown etiology that affects multiple organs. Patients diagnosed with sarcoidosis usually present with nonspecific symptoms: fatigue, fever, weight loss, and respiratory symptoms such as cough and dyspnea; 50% of the patients are asymptomatic at the time of diagnosis. In 90% of patients, sarcoidosis targets hilar and mediastinal lymph nodes. In rare cases, it presents solely in the breast with no other symptoms. The diagnosis is established based on compatible clinical and radiological findings and supported by histological evidence in 1 or more organs of non-caseating epithelioid cell granulomas in the absence of organisms or particles. Case Report: We herein present a unique case of a 27-year-old woman who presented with pain and swelling in her left breast. On examination, the left breast revealed multiple, firm-hard, and tender masses. Breast ultrasound showed large loculated focally dilated ducts with significant periductal vascularity and inflammation. Fine-needle aspiration (FNA) showed an inflammatory process with granulomatous formation. An ultrasound-guided core biopsy, which was histologically consistent with granulomatous mastitis, and elevated angiotensin-converting enzyme (ACE) levels confirmed a diagnosis of sarcoidosis. The patient was started on IV steroids followed by oral prednisolone and azathioprine. During treatment, the mass size decreased and the pain substantially improved. Conclusion: It is important to consider sarcoidosis in a patient who presents with only pain and swelling in the breast to ensure early diagnosis and initiate treatment, improving the patient’s overall prognosis.
