Optimizing the use of cadavers by integrating pathology during anatomy dissection.

An accurate knowledge of anatomy, especially natural variation within individuals, is of vital clinical importance. Cadaver dissection during anatomical training may be a valuable introduction to pathology for undergraduate students, which can contribute greatly to a successful medical career. The purpose of this study was to determine the extent and type of pathology lesions in a cadaver population (n = 127) used for medical dissection. This was done to gauge whether sufficient pathology lesions representative of all the organ systems were present in the cadaver population to warrant the use of cadavers as an additional pathology learning resource. This study demonstrated a wide variety of pathology lesions in different organ systems. The respiratory system was most affected with pulmonary tuberculosis (TB) lesions being the most common finding (seen in 76% of cadavers) followed by bronchopneumonia and emphysema. Other common pathology findings included atherosclerosis, colonic diverticula, and chronic pyelonephritis. Skeletal fractures and degenerative joint disease were also noted. This study shows that cadaveric dissection offers a chance to alert and expose students to a wide variety of gross pathology and histopathology. It has been suggested that most medical students will practice in primary health care and as such more attention should be given to the pathology of commonly encountered diseases. This is particularly true for developing countries, where diseases such as TB are commonly encountered. The integration of pathology into the dissection hall may therefore be beneficial to student learning while simultaneously optimizing the use of cadaver material.

Sudden and unexpected deaths in an adult population, Cape Town, South Africa, 2001-2005.

BACKGROUND: According to the regulations of the National Health Act, all 'sudden and unexpected' deaths in South Africa should be referred to Forensic Pathology Services (FPS) for further investigation. OBJECTIVES: We aimed to determine the final outcomes of forensic postmortem examinations in 'sudden and unexpected' adult deaths referred to Tygerberg FPS between 2001 and 2005. METHODS: The study was a retrospective descriptive study. Demographic and autopsy data from adult cases of 'sudden and unexpected deaths' referred to Tygerberg FPS were collected and analysed. Results. Some 816 adult cases of 'sudden' deaths were studied. The presumed manner of death was natural in 645 (79.0%) cases, unnatural in 99 (12.2%), and undetermined in 72 (8.8%). Diseases of the cardiovascular, respiratory and central nervous systems accounted for the majority of natural deaths. Infectious diseases accounted for most deaths in the youngest age group studied (18 - 29 years); however, ischaemic heart disease was the most prevalent cause of death in the total study population. CONCLUSIONS: This study highlighted the lack of useful pre-autopsy information and therefore the performance of 'unnecessary' medicolegal autopsies in a resource-limited country. Clinicians could ease the burden by giving useful information when referring cases to FPS. Feedback should be given to family members, especially where the cause of death may have an impact on surviving family members.

Errors in the completion of the death notification form.

OBJECTIVES: To determine the frequency of errors in the cause of death sequence and to assess the completeness of information recorded on death notification forms (DNFs). DESIGN: A population-based descriptive study. SETTING: All residents of two residential areas in the Cape Town metropole who died during the period 1 June 2003 to 31 May 2004. METHODS: We examined DNFs for pre-specified major and minor errors, assessed potential predictors of major errors using multivariate analysis, and assessed the DNFs for completeness in terms of particulars of the deceased, the informant and the health professional certifying death. RESULTS: 844 DNFs were evaluated. Errors were found in 91.7% (95% CI 89.7 - 93.4%) of DNFs, and 43.4% (95% CI 40.1 - 46.7%) had at least one major error, most commonly an illogical cause of death sequence. Factors that seemed to affect the frequency of major errors were the number of lines of the cause of death sequence that had been completed, the age, gender and area of residence of the deceased, and the type of facility where the DNF had been completed. Varying levels of completeness were found for different items of information with some questions such as the education, occupation, usual business and smoking history of deceased being largely ignored by health professionals. CONCLUSION: An unacceptably high proportion of DNFs in the greater Cape Town area contain errors sufficiently serious to affect the accuracy of cause of death coding. This has far-reaching implications for the reliability of mortality data in South Africa. Educational, managerial and administrative interventions are urgently needed to improve the standard of DNF completion.
