The authors report on one case of Wolfram syndrome, a rare condition, which is characterized by juvenile onset diabetes mellitus, diabetes insipidus, optic atrophy and sensorineural deafness. The findings of this 13-year follow-up show that this patient developed typical neurological complications of long-standing diabetes mellitus as in the common type 1 variant. Moreover, some peculiar signs occurred such as anosmia, ophthalmoplegia interna, and central nystagmus. Since Wolfram syndrome is probably part of a more generalized neurodegenerative disorder, long-term prognosis will depend both upon the severity of chronic diabetic complications and upon the rapidity, by which degeneration of cerebellar, pontine and brain stem structures appear. Prognosis of the cardinal clinical signs is such that optic atrophy, though usually quite rapid in the beginning, generally does not lead to complete blindness. Sensorineural hearing loss progresses very slowly so that deafness might be expected exceptionally only. The hearing deficit in classical diabetics, however, is of retrocochlear origin. Therefore, in Wolfram syndrome, a combined inner-ear and retrocochlear hearing loss may occur.

Eye movement tests (saccade tests: reaction time, peak velocities and accuracy, and the eye tracking test) were studied in 53 insulin-dependent diabetic (IDDM) patients and 42 randomly selected non-diabetic control subjects, aged between 20 and 40 years. All subjects had central visual acuity of at least 0.1 in one eye, and none had ophthalmoplegia. The reaction time was longer and the accuracy decreased in the saccade test in diabetic patients as compared to control subjects. Peak velocities tended to be slower in diabetic patients, but no significant differences between diabetic and non-diabetic subjects were observed. The maximum eye movement velocities were reduced at all target velocities in diabetic patients as compared to control subjects. These findings can be explained on the basis of many potential disturbances in the central nervous system. Only the duration of diabetes had a clear association with maximum smooth pursuit eye movement velocities in the eye tracking test. Microvascular complications (retinopathy, nephropathy), autonomic neuropathy or metabolic control (high fasting blood glucose and glycated hemoglobin A1c) had no clear association with the results of eye movement tests. In conclusion, insulin dependent diabetes mellitus deteriorates the visuomotor responses.

Background: Mucormycosis is a rapidly progressive, angioinvasive fungal infection that has a predilection for the paranasal sinuses and adjacent mucosa. Rhinocerebral mucormycosis (RCM) is the most common form and is known to invade the skull base and its associated blood vessels-leading to mycotic aneurysms, ischemic infarcts, and intracerebral hemorrhage. There are documented cases of mechanical thrombectomy in ischemic stroke due to RCM, however, there are no known cases that were diagnosed primarily by histological and pathological analysis of the embolus. We present a case of treatment of large vessel occlusion that led to the diagnosis and treatment of RCM. Case Presentation: A 21 year-old male inmate with history of type 1 diabetes presented with generalized weakness, abdominal pain, right eye blindness, and ophthalmoplegia after an assault in prison. He underwent treatment for diabetic ketoacidosis, but subsequently developed left hemiplegia and was found to have complete occlusion of his right internal carotid artery. He underwent successful mechanical thrombectomy and pathological analysis of the embolus revealed a diagnosis of mucormycosis. He completed a course of amphotericin B, micafungin, and posaconazole. With the aid of acute rehabilitation he achieved a modified Rankin score of 2. Discussion: We review the pathogenesis, diagnosis, and treatment of RCM. A comprehensive multidisciplinary approach is critical in the management of this often-fatal disease. Early diagnosis and treatment are essential in RCM as delaying treatment by more than 6 days significantly increases mortality. Treatment includes surgical debridement and intravenous antifungal therapy (amphotericin B + micafungin or caspofungin) for a minimum of 6-8 weeks.
