Likely mechanisms for sudden and unexpected death in epilepsy (SUDEP) are cerebrogenic cardiac arrhythmias, or central respiratory depression occurring during the peri-ictal period. Pathologists should be informed of the circumstances of the death, severity of seizures, seizure control and the certainty of the clinical diagnosis of epilepsy; this allows accurate clinicopathological correlation. SUDEP autopsies include neuropathological assessment, histological examination of other organs and toxicology, and require the elimination of other causes of sudden death. Macroscopic (non-fatal) abnormalities described in SUDEP include evidence of previous cerebral injury, hippocampal sclerosis and cerebellar atrophy. Histological examination may reveal neuronal loss and gliosis consistent with seizure-related brain injury. Hippocampal sclerosis shows subfield-specific patterns of neuronal loss, granule cell dispersion and mossy fibre sprouting. Rarely, acute neuronal injury is seen as evidence of a more recent cerebral event. This article discusses the pathological findings and possible mechanisms in SUDEP, and future directions for pathology-based research.</p></div>","PeriodicalId":87954,"journal":{"name":"Current diagnostic pathology","volume":"13 5","pages":"Pages 389-400"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.cdip.2007.05.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136901613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiologists have refined criteria progressively for the definition of sudden death, while cardiologists have investigated relevant risk factors, especially in patients with cardiac failure and with inherited diseases of cardiac muscle.

In this article, the methods that should be used in routine practice are described. The ideal autopsy involves careful scrutiny of the clinical records, a full macroscopic and microscopic examination, further laboratory tests and the formulation of a final diagnosis. In addition to a full written report, a synoptic proforma summary is desirable. If a uniform method of investigation is adopted, it will lead to improvements in standards of practice, allow meaningful comparisons between different communities and regions, and, most importantly, permit future trends in the patterns of disease that cause sudden death to be monitored.</p></div>","PeriodicalId":87954,"journal":{"name":"Current diagnostic pathology","volume":"13 5","pages":"Pages 366-374"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.cdip.2007.05.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136901611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in recent decades, it has become clear that most of this syndrome is related to discontinuous spread from the appendix. Despite the uniformly malignant clinical presentation noted among all histological grades of fully developed PMP, the pathological nomenclature advocated by some authors has continued to include non-malignant terms (reminiscent of the ovarian tumours classified as borderline) for those frequent cases with very-well-differentiated histology. This article will review the clinical and pathological features of PMP in the context of the literature, and maintain that, regardless of how well differentiated they are, all cases of PMP are examples of mucinous carcinoma. Grading as either low- or high-grade carcinoma is indicated for prognostication.

The gastritis pattern is determined by a person's acid secretory status, which is the major determinant of disease outcome(s). The natural history of <em>H. pylori</em> gastritis is for the inflammation to progress from the antrum into the adjacent corpus, resulting in an atrophic front of advancing injury, leading to a reduction in acid secretion, loss of parietal cells, and development of atrophy.
