This is a timely, concise, eminently practical, thoughtfully, even tenderly, written 28 page report of a recent WHO Expert Committee meeting on the health problems of adolescence. The members and the consultants to the Committee deftly summarize the major worldwide trends affecting our adolescent population. The size of this population is staggering; in the age group 15-19 years alone there are already 300 million adolescents in the world, and there seems every likelihood that these numbers will increase rapidly during the next decade.

STANDARDIZATION of terminology for drugs and scientific substances appears to be a highly desirable goal. Exchange of information through publication and individual communication would be far less subject to misinterpretation if nomenclature were precise and unchanged. Furthermore, increase in world travel makes it more necessary than ever that patients, physicians, and pharmacists be able severally to request and comply with requests for drugs without worry about differences in names. International health co-operation and regional health program would obviously benefit from simplification of terminology. The situation has recently been reviewed by P. Blanc, Secretary of the World Health Organization Expert Committee on the International Pharmacopoeia, before the International Pharmaceutical Federation. His paper has been summarized in the Chronicle of the World Health Organization, for November 1952, volume 6, page 322, from which the following extracts are taken: "At first sight it might seem that, for the numerous drugs which are chemical compounds, the chemical names could be used; but the latter are often so complicated that manufacturers and sales agents spontaneously adopt simpler and shorter names. Obviously `riboflavine' sounds better and is more easily remembered than 6:7-dimethyl-9-(D-1'-ribityl)izo-alloxazine. But, unfortunately, the same substance is known elsewhere by the name of `lactoflavine' or `vitamin B2'. Another example may be cited, namely that of the methadone hydrochloride of the Pharmacopoea Internationalis (6-dimethylamino-4,4-diphenyl-3-heptanone), which is known in different countries under the following names: amidone, miadone, diadone, diaminon, mephenon, symoron, etc.

Abstract The World Health Organization (WHO) is in the process of developing the 11th edition of the International Classification of Diseases (ICD–11). Part of this process includes replacing mental retardation with a more acceptable term to identify the condition. The current international consensus appears to be replacing mental retardation with intellectual disability. This article briefly presents some of the issues involved in changing terminology and the constraints and conventions that are specific to the ICD.

Context.— In 2016 the World Health Organization published a revised classification of testicular neoplasms based upon advances in understanding their pathogenesis and molecular biology. The rationale for this revision and additional clinically relevant observations were the topics of a talk given to the Houston Society of Clinical Pathologists in April 2017. This paper summarizes that talk. Objective.— To summarize and explain the most important changes to the classification of testicular neoplasms in the World Health Organization 2016 revision. Data Sources.— Peer-reviewed published literature and contributions by individuals with expertise in this area that were also reviewed by genitourinary pathologists. Conclusions.— Most changes occurred in the germ cell tumor classification, including replacement of the terms intratubular germ cell neoplasia unclassified and carcinoma in situ by germ cell neoplasia in situ; subdivision of the tumors into 2 main categories, those derived from germ cell neoplasia in situ and those not derived from germ cell neoplasia in situ; distinction of germ cell neoplasia in situ from germ cells with delayed maturation and pre–germ cell neoplasia in situ; expansion of the trophoblastic tumor category to include epithelioid trophoblastic tumor and cystic trophoblastic tumor; and substitution of spermatocytic tumor for spermatocytic seminoma and its placement in the non–germ cell neoplasia in situ group. Other revisions included eliminating sclerosing Sertoli cell tumor as a distinct entity; the recognition of intratubular hyalinizing Sertoli cell tumor; and acceptance of the role of undifferentiated gonadal tissue in the pathogenesis of gonadoblastoma.

According to the World Health Organization histological classification of bronchial tumors, clear and giant cell carcinomas are two subtypes of large cell carcinoma. As clear and giant cells can also be observed in other types of bronchial carcinoma, we investigated the frequency of the finding of these cells in different histological types. The tumor size and degree of differentiation, the amount of necrosis and keratinization, and the presence of giant and clear cells were analyzed. Statistical analysis by χ2 test showed (for all classified histological types of bronchial carcinomas, except small cell carcinoma) that: 1) larger tumors had a great quantity of giant cells (P < 0.05; P < 0.01), 2) large tumors had more clear cells (P < 0.05; P < 0.01) and 3) tumors with a greater amount of necrosis had a larger number of giant and clear cells (P<0.05; P < 0.01). Findings of an identical cytological characteristic can cause some difficulty in determination of bronchial cancer.

Physical medicine and rehabilitation—physiatry—is the medical specialty focusing on the restoration of functional status of patients with musculoskeletal, nervous system, or congenital disorders. The World Health Organization defined disability and created the International Classification of Functioning, Disability, and Health. With this classification, a physiatrist addresses the 3 domains of disability: impairment, activity limitation, and restricted participation.
