A second edition of the Histological Typing of Upper Respiratory Tract Tumours in the WHO series International Histological Classification of Tumours was published in 1991. The new edition has been entitled Histological Typing of Tumours of the Upper Respiratory Tract and Ear. The task of revising the first edition, which was published in 1978, was undertaken at the WHO Center for Upper Respiratory Tract Tumours by K. Shanmugaratnam in collaboration with L. H. Sobin and pathologists in 8 countries. Several tumour types have been added to the classification, and some have been redefined in light of current knowledge. This presentation outlines the changes in the revised WHO classification as regards tumours of the larynx, hypopharynx, and trachea and discusses the grounds for said revisions.

Infertility is an important medical issue that has serious medical and psychosocial effects on affected individuals. In 2003, the Iraqi community suffered from profanation acts because of conflicts in the country. Toxic chemicals and radioactive materials caused numerous injuries and deaths. The people who survived these horrific events eventually suffered either from cancer or infertility. The aim of this study was to determine the levels of malondialdehyde (MDA) and some trace elements in the seminal plasma of infertile males and determine their effects on sperm parameters. This study included 41 infertile males 18-40 years old. Levels of MDA, zinc, copper and magnesium were measured in their semen via spectrophotometry. According to the classification of the World Health Organisation, the patients were classified into three groups: normospermia, oligospermia and asthenspermia. Results showed significant differences in MDA and zinc levels among the three groups (p < 0.001). Moreover, results showed a mildly positive correlation between MDA levels and sperm count (r = 0.57). This study established that levels of MDA and some trace elements contribute to male infertility.

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.

Contemporary Management

The management of low-grade glioma (LGG) is shifting as evidence has emergedthat refutes the previously commonplace imaging-based ‘watch and wait’ approach, in favour of early aggressive surgical resection. This coupled with the recent 2016 update to the World Health Organisation Classification of Tumours of the Central Nervous System is changing LGG imaging and management. Recently in Practical Neurology the contemporary management of low-grade glioma and the changes to this grading system were discussed in detail. 1 In this complementary article, we discuss the role of imaging in the diagnosis, surgical planning and post-treatment follow-up of LGG. We describe the principles of imaging these tumours and use several cases to highlight some difficult scenarios.
