Bibliographic landmarks in the history of dermatology.

The current advancements in our understanding of cutaneous diseases should not obscure our appreciation for the past and the achievements of the founders of dermatology. Their observations, ideas, discoveries, and writings shaped the development of the specialty, influence daily practices today, and serve as the foundation for future research endeavors. This article reviews the history of outstanding contributions that were preserved in enduring landmark works on which the whole knowledge of skin diseases rests. From the earliest books written with meager prior information to the impressive 19th century texts and atlases providing significant advances, these volumes marked and recorded defining moments in the evolution of dermatology.

Medicinal plants and Alzheimer's disease: Integrating ethnobotanical and contemporary scientific evidence.

The use of complementary medicines such as plant extracts in dementia therapy, varies according to the different cultural traditions. In orthodox Western medicine, contrasting with that in China and the Far East for example, pharmacological properties of traditional cognitive or memory enhancing plants have not been widely investigated in the context of current models of Alzheimer's disease. An exception is Ginkgo biloba in which the ginkgolides have antioxidant, neuroprotective, and cholinergic activities relevant to Alzheimer's disease mechanisms. The therapeutic efficacy of Ginkgo biloba extracts in Alzheimer's disease in placebo-controlled clinical trials is reportedly similar to currently prescribed drugs such as tacrine or donepezil and, importantly, undesirable side effects of Ginkgo biloba are minimal. Old European reference books (eg, medical herbals) document a variety of other plants such as Salvia officinalis (sage) and Melissa officinalis (balm) with memory improving properties, and cholinergic activities have recently been identified in extracts of these plants. Precedents for modern discovery of clinically relevant pharmacological activities in plants with long-established medicinal use include, for example, the interaction of alkaloid opioids in Papaver somniferum (Opium poppy) with endogenous opiate receptors in the brain. With recent major advances in understanding the neurobiology of Alzheimer's disease, and as yet limited efficacy of so-called rationally designed therapies, it may be timely to re-explore historical archives for new directions in drug development. This article considers not only the value of an integrative traditional and modern scientific approach to developing new treatments for dementia, but also in the understanding of disease mechanisms. Long before the current biologically based hypothesis of cholinergic derangement in Alzheimer's disease emerged, plants now known to contain cholinergic antagonists were recorded for their amnesic and dementia-inducing properties.

Colon cancer survival rates with the new American Joint Committee on Cancer sixth edition staging.

BACKGROUND: The recently revised American Joint Committee on Cancer (AJCC) sixth edition cancer staging system increased the stratification within colon cancer stages II and III defined by the AJCC fifth edition system. Using nationally representative Surveillance, Epidemiology, and End Results (SEER) data, we compared survival rates associated with colon cancer stages defined according to both AJCC systems. METHODS: Using SEER data (from January 1, 1991, through December 31, 2000), we identified 119,363 patients with colon adenocarcinoma and included all patients in two analyses by stages defined by AJCC fifth and sixth edition systems. Tumors were stratified by SEER's "extent of disease" and "number of positive [lymph] nodes" coding schemes. Kaplan-Meier analyses were used to compare overall and stage-specific 5-year survival. All statistical tests were two-sided. RESULTS: Overall 5-year survival was 65.2%. According to stages defined by the AJCC fifth edition system, 5-year stage-specific survivals were 93.2% for stage I, 82.5% for stage II, 59.5% for stage III, and 8.1% for stage IV. According to stages defined by the AJCC sixth edition system, 5-year stage-specific survivals were 93.2% for stage I, 84.7% for stage IIa, 72.2% for stage IIb, 83.4% for stage IIIa, 64.1% for stage IIIb, 44.3% for stage IIIc, and 8.1% for stage IV. Under the sixth edition system, 5-year survival was statistically significantly better for patients with stage IIIa colon cancer (83.4%) than for patients with stage IIb disease (72.2%) (P<.001). CONCLUSIONS: The AJCC sixth edition system for colon cancer stratifies survival more distinctly than the fifth edition system by providing more substages. The association of stage IIIa colon cancer with statistically significantly better survival than stage IIb in the new system may reflect current clinical practice, in which stage III patients receive chemotherapy but stage II patients generally do not.

Dusting off old books: comments on classic gynecologic pathology books of yesteryear.

Selected outstanding books from the older literature on gynecological pathology are reviewed with emphasis on drawing attention to the abundant helpful information and outstanding illustrations that are worthy of review by present-day pathologists. The first three works are Cancer of the Uterus, Myomata of the Uterus, and Adenomyoma of the Uterus by Thomas S. Cullen. The senior author of the second book is Howard A. Kelly even though he did not have any role in the preparation of the text; he was given senior authorship by Dr. Cullen as a token of appreciation to his mentor. The next book, Fibroids and Allied Tumors by Cuthbert Lockyer, is particularly noteworthy for the quality of the numerous color illustrations. The final book on the uterus is The Cervix Uteri and Its Diseases by C. Frederic Fluhmann. It provides detailed coverage of the normal and pathologic aspects of the cervix, including the endocervical clefts (glands) and their abnormalities. The next three books are on the ovary: Ovarian Tumors by Samuel H. Geist, Atlas of Ovarian Tumors by Gemma Barzilai, and Endocrine Pathology of the Ovary by John McLean Morris and Robert E. Scully. The first is notable for the quality of the coverage of clinical and gross aspects of ovarian tumors and the second for the quality of the description of the microscopic features. The third book expanded the range of functioning ovarian tumors by showing that this could be a feature of tumors not usually considered hormonally active and also discussed in detail the endocrine function of non-neoplastic lesions. The final two books cover general gynecological pathology: Manual of Obstetrical and Gynaecological Pathology by John H. Teacher and Gynecological and Obstetrical Pathology by Emil Novak. Both have particularly outstanding coverage of normal histology and non-neoplastic lesions.

Paulus Aegineta, a seventh century encyclopedist and surgeon: his role in the history of plastic surgery.

Paulus Aegineta (625-690 ad), born on the island of Aegina, practiced medicine at Alexandria. The last of the eclectic Greek compilers in the Byzantine period, he wrote an Epitome of medicine in seven books. The sixth book, which is considered the best section of his work, is devoted mainly to surgery. The first edition, "editio princeps," of his Epitome was published in Greek by the Aldine press in Venice in 1528 and later translated into English for the Sydenham Society by Francis Adams of Banchory (1844-1847). Paulus was not only a compiler but also a competent and skillful surgeon. In addition to his achievements in general surgical progress, Paulus Aegineta, especially in the book on surgery, made valuable contributions in the history of plastic surgery. He may be considered as one of the originators of plastic surgery as it is known today. He described procedures varying from the treatment of nasal and jaw fractures to operations for gynecomastia, ganglion, and hypospadias. This Grecian master influenced not only his own but also the subsequent ages. Rhazes, Haly Abbas, Albucasis, Avicenna, and Fabricius ab Aquapendente were the greatest physicians influenced by Paulus Aegineta. Because the work of Paulus Aegineta was the only source for many of the surgical treatises of Arabian authors, his Epitome bridged Western and Eastern medicine and conveyed surgical experience and knowledge, including several plastic surgery procedures, to the subsequent ages.
