Altered taste and stroke: a case report and literature review.

Patients with altered taste perception following stroke are at risk for malnutrition and associated complications that may impede recovery and adversely affect quality of life. Such deficits often induce and exacerbate depressive symptomatology, which can further hamper recovery. It is important for clinicians and rehabilitation specialists to monitor stroke patients for altered taste perception so that this issue can be addressed. The authors present the case of a patient who experienced an isolated ischemic infarct affecting a primary cortical taste area. This case is unusual in that the isolated injury allowed the patient to remain relatively intact cognitively and functionally, and thus able to accurately describe her taste-related deficits. The case is further used to describe the relevant neurological taste pathways and review potential taste-related therapies.

Lemierre syndrome secondary to community-acquired methicillin-resistant Staphylococcus aureus infection associated with cavernous sinus thromboses.

BACKGROUND: Lemierre Syndrome (LS) is a highly aggressive rare disease process with a predilection for young, healthy adolescents. Often beginning with a primary cervicofacial infection, LS rapidly progresses to thrombophlebitis of the cerebral vasculature, metastatic infection, and septicemia. Untreated LS can be rapidly fatal. Thrombus within the cerebral vasculature can have devastating neurological effects. Advances in antibacterial therapy have resulted in a global decline in the incidence of LS, and clinicians may not consider LS early in the disease process. Although the mortality of LS has declined, the morbidity associated with the disease has increased, particularly the neurological sequelae. OBJECTIVES: This report will provide readers with a better understanding of the etiology, clinical presentation, evaluation methods, and appropriate treatment of LS. CASE REPORT: We present an atypical case of LS secondary to community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infection progressing to bilateral cavernous sinus and ophthalmic vein thromboses with resultant binocular vision loss secondary to optic nerve and retinal ischemia. CONCLUSION: This case highlights the importance of early recognition of LS in the setting of a community-acquired MRSA infection as the unifying condition in a young patient with multiple acute neurologic impairments.

The effects of gait impairment with and without freezing of gait in Parkinson's disease.

OBJECTIVE: To compare the effects of gait impairment without freezing of gait (FOG) versus FOG without gait impairment in Parkinson's disease (PD) on disability and quality of life. BACKGROUND: FOG is frequently characterized as the major cause of gait-related disability in PD. However, gait impairment may also result from other PD symptoms including slowing, motor asymmetry, gait variability, dystonia or stooped posture. METHODS: The Unified Parkinson's Disease Rating Scale (UPDRS), Older Americans Resources and Services Disability Scale (OARS) and the SF-12 Health Status Survey were used to evaluate patients with PD. Responses to UPDRS Items #14 (Freezing) and # 29 (Gait) were used to create 4 subgroups: 1) No FOG or gait impairment, 2) FOG, no gait impairment, 3) Gait impairment, no FOG, and 4) Both FOG and gait impairment. Disease severity, disability, and quality of life were compared across the subgroups with ANOVAs, and between subgroups with t-tests. RESULTS: 916 PD patients were divided into 4 subgroups based on their gait and freezing score (#1: n = 213, #2: n = 41, #3: n = 323 and #4: n = 339). Total UPDRS progressively increased from Group 1 through Group 4 (1 = 25.2, 2 = 33.7, 3 = 39.2, 4 = 59.2; p < 0.001). Motor UPDRS also progressively increased (1 = 17.4, 2 = 19.7, 3 = 26.9, 4 = 36.5; p < 0.0001). Similarly, disability and health-related quality of life progressively increased from Group 1 through Group 4 (Total OARS: 1 = 15.3, 2 = 17.2, 3 = 18.9, 4 = 28.4; p < 0.001). Group 3 (Gait impairment, no FOG) showed greater disease severity than Group 2 (FOG, no gait impairment; Total and Motor UPDRS; p < 0.05), but the difference did not reach significance for disability or quality of life. CONCLUSIONS: Gait impairment without FOG was associated with greater disease severity than FOG without gait impairment. The combination of gait impairment and FOG was associated with the greatest disease severity and disability. These results show differential effects of diverse features of gait impairment in PD and demonstrate the importance of gait features unrelated to freezing.
