Acceptance of a psychiatric screening questionnaire by general practice attenders.
The general health questionnaire (GHQ) is a self-reporting psychiatric screening questionnaire which has been tested and validated in a number of languages and cultural settings. The translated and validated 30 item GHQ was given to a selected sample of women between 15 and 49 years attending a suburban general practice, as a part of a study on emotional disorder. The acceptance of the questionnaire was high with a compliance of 91.5% from those who were invited to participate. The majority of respondents showed much interest and willingness in filling in the questionnaire.

Treating alcohol problems in Sri Lanka.
Treatment in settings where facilities are limited poses many challenges. Attempts are being made to use untrained but committed people to help dependent persons maintain abstinence after withdrawal. This experience makes us question the need for highly trained specialized staff in helping in this task.

Behavior therapy in Sri Lanka.
The development of behavior therapy in Sri Lanka is presented. Its beginnings in the decade of the 70s in the two medical schools in Colombo and Peradeniya and its current status are reviewed, and future prospects are discussed. The need for developing and expanding behavior therapy practice in the country, and possible directions in training, are commented on.

The ependyma of the saccular pineal gland in the non-eutherian mammal Trichosurus vulpecula. A scanning electron microscopic study.
The pineal gland in the possum is represented by a thickening in the wall of the pineal recess. A superficial pineal body and a pineal stalk are characteristically lacking. The ependyma related to the gland is specialized but differs markedly from the lining in other circumventricular organs in form and in surface morphology. Two distinct topographic zones have been recognized. In the middle is a mass of cells which form a prominent knobby-surfaced central zone. These cells are characterized by the absence of cilia, the paucity of microvilli and blebs and the presence of processes which overlap adjacent cells. A surface pattern formed of cell outlines was lacking. it is suggested that the central zone is lined by pinealocytes, supporting cells and the processes of both cell types. Most of the central zone is surrounded by an intermediate zone of variable width. The latter region has been observed to possess a circumventricular organ-type surface morphology. It is sparsely ciliated, almost totally covered by a carpet of microvilli and it exhibits a variety of surface specializations. Supraependymal cells and various transitory supraependymal cell processes are also present. Outside the specialized ependyma is the peripheral zone which like the regular ventricular lining is densely ciliated. Supraependymal processes are found among the clusters of cilia, or rarely, on the surface of the ciliary bed. Season and sex related differences in surface ultrastructure were not observed.

TB or not TB?
These 3 cases illustrate what we believe to be unusual presentations of tuberculosis. In no case was there conclusive proof of infection with Mycobacterium tuberculosis using histological, microbiological or radiological techniques. All were treated empirically with anti-tuberculous medication, with complete recovery. With the re-emergence of tuberculosis, there may be a rise in such cases, and the importance of their recognition and empirical treatment is discussed.
