ABSTRACT

PURPOSE OF REVIEW: Standard treatment for early-stage squamous cell cancer of the anal canal (SCCA) includes concurrent chemotherapy and radiation to achieve curative intent. Treatment options are limited, however, especially with locoregional disease relapse occurring in 20-30% of patients and about 10-30% of patients presenting with metastatic disease. With more than 90% of SCCAs occurring in the setting of HPV, immune-based therapies are now the target of possible new treatments for this rare disease. This review highlights the role of immunotherapy in HPV-associated SCCA. RECENT FINDINGS: Immunotherapy has been shown to extend progression-free survival and overall survival in various solid malignancies, including SCCA. So far, single-agent monotherapy with either nivolumab or pembrolizumab has shown durable clinical response with a tolerable side effect profile. The 2018 NCCN guidelines now advise nivolumab or pembrolizumab monotherapy as second-line treatment in the management of metastatic SCCA. Further investigation with immunotherapy continues to be critical for such a rare malignancy with few treatment options.

ABSTRACT

Tamoxifen is a selective estrogen- receptor modulator commonly associated with an increased risk of thrombotic events, including cere- bral venous thrombosis. Ihe superior sagittal sinus appears to be the most affected site of cerebral venous thrombosis in patients with a history of malignancy. However, the underlying mechanism of tamoxifen- induced hypercoagulability and location of cerebral venous thrombosis are notwellunderstood. Here, we present a case of a 47-year-old female with a history of breast cancer, on tamoxifen for 10 months, found to have superior sagittal sinus thrombosis with additional thrombosis of the draining cortical veins. Furthermore, we review similar cases published in literature. We recommend that physicians should be aware ofthe potential of developing superior sagittal sinus thrombosis in patients who take tamoxifen and warn patients of this adverse event when prescribing the medication.

ABSTRACT

OBJECTIVE: To estimate the frequency and correlates of involuntary emotional expression disorder (IEED) in Parkinson's disease (PD) using the Center for Neurologic Study-Lability Scale (CNS-LS) and recently-proposed diagnostic criteria for IEED. BACKGROUND: IEED is characterized by uncontrollable emotional episodes, typically unrelated to or in excess of the underlying mood, and occurring with minimal or no stimulus. IEED has been reported to occur in many neurological disorders and neurodegenerative diseases, but its prevalence and correlates in PD have not been well studied. Additionally, there is no published research using recently-proposed IEED diagnostic criteria in any population. METHODS: 193 patients with idiopathic PD were assessed with a neuropsychiatric battery, including the CNS-LS and the 15-item Geriatric Depression Scale (GDS-15). A subset (N=100) was also administered a diagnostic interview by a blinded rater that applied criteria for both IEED and Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) depressive disorders. RESULTS: Applying formal diagnostic criteria, 7.0% of patients were diagnosed with IEED, and an additional 7.0% had subsyndromal IEED symptoms. Applying recommended CNS-LS cutoff scores from other populations, either 42.5% (cutoff > or =13) or 16.6% (cutoff > or =17) screened positive for IEED. Depressive symptoms were associated with higher CNS-LS scores (B[SE]=0.27[.08], P=.001) but not with a diagnosis of IEED (odds ratio=1.1, [95% CI=1.0-1.3], P=.16). The CNS-LS had poor discriminant validity for an IEED diagnosis (AUC=.79, no cutoff value with sensitivity and specificity both >60%). CONCLUSIONS: IEED and depression are overlapping but distinct disorders in PD. IEED symptoms may occur in up to 15% of PD patients, but a disorder occurs in only half of those, suggesting that often IEED symptoms are not clinically significant in this population. The CNS-LS does not appear to be a good screening instrument for IEED in PD, in part due to its high correlation with depressive symptoms.

ABSTRACT

Does the parietal lobe have a critical role in memory? The neuroimaging literature indicates that it has an important role, especially in episodic memory. However, the neuropsychological literature suggests that its role is more limited to attentional, spatial, or imagery aspects of memory. Here, we present data to adjudicate this disagreement. Two patients with bilateral parietal lobe damage received detailed assessments of their autobiographical memories. The results show that although both patients easily recalled various memories, their freely recalled memories were relatively impoverished, lacking in detail. This deficit was ubiquitous, and not limited to spatial or perceptual aspects of memory. The memory deficit disappeared when memory was specifically probed by asking pointed questions. Additional tests show that it is unlikely that their free recall deficit can be explained by general mental imagery problems. In sum, the parietal lobe appears to have a critical role in recollection aspects of episodic memory.
