Carotid Artery Occlusion by Rhinoorbitocerebral Mucormycosis

Mucormycosis is the third most common invasive fungal infection that particularly occurs in immunocompromised patients. Intracranial and extracranial arteriovenous vasculopathy is a complication that makes this disease more complex and difficult to treat. We describe a 23-year-old female, who presented to her local hospital with acute blindness and diabetic ketoacidosis-induced coma requiring intensive care treatment. She was found to have lesions in the nasal sinuses, orbit, and frontal base. The left carotid artery was occluded from its origin in the neck to the supraclinoid segment and left cavernous sinus involvement. No cerebral infarction was noted. Biopsies obtained by endonasal debridement confirmed mucormycosis. In addition to antimicrobial therapy, she underwent several multidisciplinary approaches to treat her disease. Multiple endonasal, and cranial procedures were done including bilateral orbital exenteration. After prolonged treatment on the intensive care unit she made a remarkable recovery to the point where she was communicating verbally and had normal limb movements and later discharged home. She remained alive and well for two months, but later succumbed to a recurrence of her disease. In conclusion, mucormycosis-induced vasculopathy is a complex problem, which merits aggressive treatment of this invasive disease. It is normally regarded as an indicator of grave prognosis

New onset refractory status epilepticus due to primary angiitis of the central nervous system

Primary Angiitis of the central nervous system is a rare and poorly understood variant of vasculitis. We narrate a case of a 46-year-old male who presented with new onset refractory status epilepticus mimicking autoimmune encephalitis. In this case we are reporting clues that could be useful for diagnosis and extensive literature review on the topic

Phenotypic Variability of MEGF10 Variants Causing Congenital Myopathy: Report of Two Unrelated Patients from a Highly Consanguineous Population

Congenital myopathies are rare neuromuscular hereditary disorders that manifest at birth or during infancy and usually appear with muscle weakness and hypotonia. One of such disorders, early-onset myopathy, areflexia, respiratory distress, and dysphagia (EMARDD, OMIM: 614399, MIM: 612453), is a rare autosomal recessive disorder caused by biallelic mutations (at homozygous or compound heterozygous status) in MEGF10 (multiple epidermal growth factor-like domains protein family). Here, we report two unrelated patients, who were born to consanguineous parents, having two novel MEGF10 deleterious variants. Interestingly, the presence of MEGF10 associated EMARDD has not been reported in Saudi Arabia, a highly consanguineous population. Moreover, both variants lead to a different phenotypic onset of mild and severe types. Our work expands phenotypic features of the disease and provides an opportunity for genetic counseling to the inflicted families

Characteristics and treatment results of patients with gastroenteropancreatic neuroendocrine tumors in a tertiary care centre

Abstract Background Gastroenteropancreatic Neuroendocrine tumors (GEP-NET) are rare neoplasms with limited reported data from the Middle East. Our study aims to report the clinicopathological feature, treatment patterns, and survival outcomes of patients with GEP-NET from our part of the world. Methods Medical records of patients diagnosed with GEP-NET between January 2011 and December 2016 at a single center in Saudi Arabia were reviewed retrospectively, and complete clinicopathological and treatment data were collected. Patients’ survival was estimated by the Kaplan–Meier method. Results A total of 72 patients were identified with a median age of 51 years (range 27–82) and male-to-female ratio of (1.1). The most common tumor location was the pancreas (29.1%), followed by small bowel (25%), stomach (12.5%), rectum (8.3%), colon (8.3%), and appendix (6.9%). Forty-one patients (57%) had well-differentiated grade (G)1, 21 (29%) had G2, and 4 (6%) had G3. In five patients, the pathology was neuroendocrine carcinoma and in one it could not be classified. 54.2% of the patients were metastatic at diagnosis. Forty-two patients underwent surgical resection as primary management while 26 underwent systemic therapy, three patients were put on active surveillance, and one was treated endoscopically with polypectomy. The 5-year overall survival and progression-free survivals were 77.2% and 49%, respectively, for the whole group. Patients with G1 and 2 disease, lower Ki-67 index, and surgically treated as primary management had significantly better survival outcomes. Conclusion Our study suggests that the most common tumor locations are similar to western reported data. However, there seems to be a higher incidence of metastatic disease at presentation than in the rest of the world
