RESUMEN
Aceruloplasminemia (ACP) is a rare genetic disorder that manifests in adulthood due to mutations in the CP (ceruloplasmin) gene, causing iron accumulation and neurodegeneration. Clinically, ACP presents with a range of symptoms, including mild microcytic anemia, diabetes mellitus, liver disease, retinopathy, progressive neurological symptoms such as cerebellar ataxia, involuntary movements, parkinsonism, mood and behavior disorders, and cognitive impairment. We present the case of a 53-year-old female with a history of first-degree consanguinity and a sister with anemia. At six years old, she developed asthenia, leading to multiple hospitalizations for acute hemolytic anemia requiring transfusions and iron therapy. She exhibited later memory disturbances, slowed comprehension, social withdrawal, and school discontinuation. At the age of 51, she developed gait disturbances, unexplained falls, and cognitive decline. One year later, cranial CT revealed a chronic bilateral subdural hematoma. On admission at 53, she had anarthria, right hemiparesis, diffuse rigidity, mouth dystonia, oculomotor paralysis, and intellectual deterioration. MRI showed superficial cortical and leptomeningeal hemosiderin deposits and bilateral signal anomalies in various deep brain regions. EEG revealed paroxysmal anomalies and abdominal MRI indicated hepatic iron overload. Laboratory tests confirmed ACP. This case highlights the rare and severe neurological and systemic manifestations of ACP, emphasizing the importance of early diagnosis and intervention in such degenerative diseases to prevent irreversible neurological complications.
RESUMEN
Stiff person syndrome (SPS) is a progressive autoimmune disorder characterized by muscle rigidity, frequent falls, and spasms, affecting primarily women. Recent advances have linked SPS to specific antibodies, such as anti-glutamic acid decarboxylase (GAD)-65, but effective treatments remain elusive. We report the case of a 53-year-old female who developed chronic lower back pain, tingling paresthesias, and progressive rigidity in the lower limbs. Electromyographic examination revealed muscle spasms and co-contractions, along with severe rigidity and reactive spasms upon touch. Imaging studies showed a polymyomatous uterus and no hypermetabolic lesions. She was diagnosed with stiff person syndrome with positive anti-GAD65 autoantibodies. Patient was treated with methylprednisolone, oral corticosteroids, gabapentin, baclofen, alprazolam, immunoglobulins, and rituximab, leading to moderate improvement in her condition. This case report aims to highlight the association between SPS and anti-GAD65 autoantibodies, emphasizing the importance of early diagnosis and comprehensive management.
RESUMEN
Introduction: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is known as a therapy of choice of advanced Parkinson's disease. The present study aimed to assess the beneficial and side effects of STN DBS in Moroccan Parkinsonian patients. Material and Methods: Thirty five patients underwent bilateral STN DBS from 2008 to 2016 in the Rabat University Hospital. Patients were assessed preoperatively and followed up for 6 to 12 months using the Unified Parkinson's Disease Rating Scale in four conditions (stimulation OFF and ON and medication OFF and ON), the levodopa-equivalent daily dose (LEDD), dyskinesia and fluctuation scores and PDQ39 scale for quality of life (QOL). Postoperative side effects were also recorded. Results: The mean age at disease onset was 42.31 ± 7.29 years [28-58] and the mean age at surgery was 54.66 ± 8.51 years [34-70]. The median disease duration was 11.95 ± 4.28 years [5-22]. Sixty-three percentage of patients were male. 11.4% of patients were tremor dominant while 45.71 showed akinetic-rigid form and 42.90 were classified as mixed phenotype. The LEDD before surgery was 1200 mg/day [800-1500]. All patients had motor fluctuations whereas non-motor fluctuations were present in 61.80% of cases. STN DBS decreased the LEDD by 51.72%, as the mean LEDD post-surgery was 450 [188-800]. The UPDRS-III was improved by 52.27%, dyskinesia score by 66.70% and motor fluctuations by 50%, whereas QOL improved by 27.12%. Post-operative side effects were hypophonia (2 cases), infection (3 cases), and pneumocephalus (2 cases). Conclusion: Our results showed that STN DBS is an effective treatment in Moroccan Parkinsonian patients leading to a major improvement of the most disabling symptoms (dyskinesia, motor fluctuation) and a better QOL.
RESUMEN
BACKGROUND: Carbon monoxide (CO) intoxication is a leading cause of severe neuropsychological impairments. Peripheral nerve injury has rarely been reported. It consists usually in a demyelinating polyneuropathy or mononeuropathy affecting mainly the lower limbs. Isolated involvement of both upper extremities has been described in only 4 patients related to root damage. We report the first case of bilateral brachial plexus injury following CO poisoning and review all previous CO-induced neuropathy described in literature. CASE PRESENTATION: After being unconscious for three hours, a 42 years old man experienced bilateral brachial weakness associated with edema of the face and the upper limbs. Neurological examination showed a brachial diplegia, distal vibratory, thermic and algic hypoesthesia, deep tendon areflexia in upper limbs. There was no sensory or motor deficit in lower extremities. No cognitive disturbances were detected. Creatine kinase was elevated. Electroneuromyogram patterns were compatible with the diagnosis of bilateral C5 D1 brachial axonal plexus injury predominant on the left side. Clinical course after hyperbaric oxygen therapy was marked by a complete recovery of neurological disorders. CONCLUSION: Peripheral neuropathy is an unusual complication of CO intoxication. Bilateral brachial plexus impairment is exceptional. Various mechanisms have been implicated including nerve compression secondary to rhabdomyolysis, nerve ischemia due to hypoxia and direct nerve toxicity of carbon monoxide. Prognosis is commonly excellent without any sequelae.
