Artificial Intelligence (AI) and Drug-Induced and Idiosyncratic Cytopenia: The Role of AI in Prevention, Prediction, and Patient Participation.

Drug-induced and idiosyncratic cytopenias, including anemia, neutropenia, and thrombocytopenia, present significant challenges in fields like immunohematology and internal medicine. These conditions are often unpredictable, multifactorial, and can arise from a complex interplay of drug reactions, immune abnormalities, and other poorly understood mechanisms. In many cases, the precise triggers and underlying factors remain unclear, making diagnosis and management difficult.

Autoantibodies Directed Against Insulin Receptor During the Course of Castleman Disease: A New Case Reaffirming Autoimmune Hypoglycemia as a Relapse Warning Signal.

Unlabelled: This case study presents the case of a 54-year-old human immunodeficiency virus (HIV)-positive male who developed type B insulin resistance syndrome (TBIRS) in conjunction with a relapse of human herpesvirus 8 (HHV8)-positive multicentric Castleman disease (MCD). This case is only the sixth reported instance of TBIRS associated with HHV8-associated MCD. The diagnosis was confirmed by the presence of anti-insulin receptor autoantibodies, and the patient was treated effectively with rituximab, with no relapse in follow-up.

Unraveling the Enigma: Food Cobalamin Malabsorption and the Persistent Shadow of Cobalamin Deficiency.

Food cobalamin malabsorption (FCM) represents a prevalent, often underdiagnosed, etiology of vitamin B12 deficiency, particularly within an aging population. Unlike pernicious anemia, an autoimmune disorder targeting intrinsic factor, FCM stems from the impaired release of cobalamin from food proteins, primarily due to age-related gastric changes, medication-induced gastric hypochlorhydria, metformin, or non-immune atrophic gastritis. The clinical presentation of FCM mirrors that of general cobalamin deficiency, encompassing a spectrum of neurological (peripheral neuropathy, cognitive decline), hematological (megaloblastic anemia), and gastrointestinal (glossitis, anorexia) manifestations.

[Management of febrile neutropenia].

Febrile neutropenia is a medical emergency requiring rapid and rigorous management considering the risk of severe infection. Febrile neutropenia is a frequent complication in patients receiving chemotherapy. Initial assessment is vital in order to decide the follow-up (outpatient treatment, conventional care or intensive care unit) and to initiate adapted antibiotic therapy as soon as possible.

Delayed Neurological Sequelae of Carbon Monoxide Intoxication Initially Treated as Infectious Meningo Encephalitis.

Unlabelled: We report the case of a 75-year-old woman admitted to the emergency department for confusion, gait disturbances and mutism associated with an inflammatory syndrome occurring 3 weeks after acute carbon monoxide intoxication. The main hypothesis upon arrival was infectious meningoencephalitis, and the patient was put on acyclovir and antibiotics in meningeal doses. After a short stay in intensive care, the patient's condition did not improve, and the revaluation of her case history and imaging studies led to the diagnosis of post-interval syndrome secondary to carbon monoxide intoxication after a 3-week asymptomatic period.

[Transthyretin cardiac amyloidosis patients in internal medicine : a 10-year retrospective study].

Introduction: Transthyretin cardiac amyloidosis is a pathology increasingly encountered in all hospital departments, including internal medicine. The aim of our study is to describe the characteristics and care pathway of patients with transthyretin cardiac amyloidosis in internal medicine and to show that the number of patients diagnosed is increasing.

Methods: Descriptive, retrospective, non-interventional, single-center study at Strasbourg University Hospitals (HUS).

Hearing Loss and Sixth Cranial Nerve Paresis after COVID-19.

Unlabelled: An 80-year-old patient was admitted to the internal medicine department for binocular diplopia and hearing loss with sudden onset. The patient had presented with SARS-CoV-2 infection 3 weeks previously and had been admitted to hospital. Complete work-up including autoimmunity, serum and LCR viral serology and MRI did not allow a diagnosis to be established.

Frostbite and Cold Agglutinin Disease: Coexistence of Two Entities Leading to Poor Clinical Outcomes.

An 83-year-old woman was admitted to the emergency department for a 7-day history of fatigue and progressive cyanosis in the feet and hands after cold exposure despite physical protective measures. Upon arrival, the patient presented with necrotic cutaneous lesions in both hands and distal lower extremities. Upon admission, hemoglobin was 7.

Spinal Cord Compression Secondary to a Spontaneous Spinal Haematoma in a Patient Newly Treated with Rivaroxaban.

Unlabelled: A 74-year-old patient anticoagulated with rivaroxaban for chronic atrial fibrillation presented to the emergency department with acute lumbar pain with progressive weakness of the lower limbs and inability to stand up. No previous trauma was reported. Neurological examination was consistent with a complete spinal cord syndrome at the level of T6.

[Acquired hemophilia as the initial manifestation of colorectal cancer's recurrence].

We report the case of an 86-year-old man presenting with a spontaneous hematoma in the left iliac muscle and previous diagnosis of colon cancer in 1998 (stage pT3N0M0) treated with transverse colectomy and considered in complete remission. After a complete study, it was possible to identify the presence of Factor VIII inhibitors antibodies that confirmed the presence of acquired hemophilia. During hospitalization the patient presented a lower gastrointestinal bleeding leading to the diagnosis of recurrence of a previously treated colorectal adenocarcinoma.

Acute Confusional State Revealing Moyamoya Disease in the Emergency Department: A Rare Entity.

Unlabelled: A 54-year-old woman was admitted to the emergency department for an acute, fluctuating altered mental status and reduced perceptual awareness of her surroundings as well as disorganized thinking. Blood tests, including for drugs, were normal. A CT scan of the brain was normal.

SARS-CoV-2 infection and psychiatric manifestations in a previous healthy patient.

Background: The clinical presentation of SARS-CoV-2 infection was initially dominated by respiratory symptoms. However, the clinical spectrum is wide and neuropsychiatric syndromes are also a source of medical concern. Our aims are to present an atypical clinical presentation of SARS-CoV-2 infection characterized by auditory hallucinations and unusual behavior and to emphasize the diversity of clinical manifestations of SARS-CoV-2 infection.
