IT IS PROVERBIAL that a fool can ask more questions than a wise man can answer. It is not proverbial that for the question-asking fool there is some hope and for the others, none. Now it is my intention on this occasion to play the fool awhile, to ask a great number of questions, and I cordially invite you to join me in this game. I want to inquire into The World of the Rheumatic Child, into his internal as well as into his external world, or, as Claude Bernard has phrased it, into his milieu interieur and into his milieu exterieur. Now there is some method to my folly, and it amounts to this. We know a great deal about the disease rheumatic fever and about its devastating effects within the body of its victim. But we do not know a great deal, indeed only a very little, about the victim within whose body the disease effects its devastations. I said—we know a great deal about the disease itself. In preparation for this talk I "re-surveyed the literature" and I found it, as I have known it to be, not only enormous in quantity but most impressive in quality. It is literally studded with masterpieces of etiologic research, of clinical surveys, of pathologic studies, of follow-up surveys, of epidemiologic analyses, and of therapeutic enterprises. In my review of the literature I came upon some old and esteemed friends whose works I had witnessed "in the making," the studies, for example, of Wyckoff, and those of Alfred Cohn; Claire Ling's penetrating statistical analyses, Pearl Raymond's biologic speculations, May Wilson's classical and encyclopedic résumé of knowledge—and upon a host of others, too numerous, really, to catalogue.

Seiring dengan kemajuan ilmu kedokteran, semakin banyak tantangan yang harus dihadapi khususnya dalam bidang epidemiologi klinik. Oleh karena itu dunia penelitian semakin dikembangkan untuk menjawab tantangan tersebut. Salah satu jenis penelitian yang popular adalah penelitian etiologi atau penelitian kausal. Dalam penelitian ini faktor confounding merupakan isu yang penting karena dapat mempengaruhi hasil penelitian. Faktor confounding berhubungan dengan determinan dan outcome membentuk sebuah segitiga. Faktor confounding harus dibedakan dengan faktor intermediet dan modifier. Diperlukan pengetahuan yang cukup untuk menentukan faktor confounding yang terlibat dan mungkin akan potensial muncul dalam penelitian serta untuk menganalisanya. Walau dapat dicegah, namun lebih baik faktor confounding diatasi melalui proses analisis agar dapat menambah wawasan penelitian dan menghindari bias penelitian.

This chapter describes the use of disease clustering methods using diarrheal disease data from a rural area of Bangladesh for which the authors created a household-level GIS database. Understanding distributions of diseases in space and time can be useful for etiologic research and socio-environmental risk factor identification. Disease clustering techniques are not only useful as etiological research tools for chronic diseases but also for infectious diseases. The magnitude of clustering in different areas can assist with the generation of hypotheses about the underlying socio-environmental causes of the clusters. Once clusters are identified, studies can then focus on the socio-environmental characteristics of the areas where clusters are found.
