Coupling HPLC to GC: why? How? With what instrumentation?

Coupling LC to GC alleviates sample preparation in the sense of preseparation, cleanup, or enrichment and replaces conventional methods such as column liquid chromatography, enrichment by or filtration through sample preparation tubes, preparative thin-layer chromatography, or liquid-liquid partitioning. LC is more efficient in separation power, more rapid, and allows fully automatic integration of sample preparation into GC. Advantages are discussed for selected applications. The transfer techniques, as well as some key requirements for an LC-GC instrument, are briefly summarized.

Italian validation of the Symptom Rating Test (SRT) and Symptom Questionnaire (SQ).

Two self-rating scales of psychological distress, the Symptom Rating Test (SRT) and the Symptom Questionnaire (SQ), have been validated in translations in Italy. They were administered in several studies to psychiatric patients (neurotics and depressives), matched controls, and patients suffering from various organic illnesses (dermatologic disorders, hypertension, secondary amenorrhea and patients undergoing amniocentesis). The SRT and the SQ sensitively discriminated between psychiatric patients and normals, between different levels of psychological distress in several of the somatic illnesses, and detected significant changes in the psychological status of patients participating in medical procedures such as amniocentesis. The scales were found to be useful in research in psychiatry and psychosomatic medicine. The findings suggest that the Italian translations are valid and sensitive scales of distress and can apparently be used as effectively in research as the original. They are likely to be of value in cross-cultural research in Canada. Both scales may be helpful in the psychological assessment of Italian immigrants in North America and Australia, especially in those whose English is poor.

Losses, Hostility, and depression.

Forty outpatients with a primary unipolar major depression of recent onset and a matched control group of employees were administered the hostility scale of the Kellner Symptom Questionnaire, depression was rated with the Hamilton Rating Scale for Depression, and life events were recorded in a structured interview. In a subgroup of depressives who had not reported losses, there was an association of hostility and depression, whereas no such association was found in depressives who had reported losses. The findings are consistent with those of previous studies showing that hostility is largely limited to a subgroup of depressives. In a substantial proportion of the depressives, depression and hostility are independent affects.

The Hamilton Depression Rating Scale in normals and depressives.

The Hamilton Rating Scale for depression (HDRS) has become the standard observer rating scale for depression, yet there are no adequate data from normal samples. The present study was carried out in northern Italy. The purposes were 1) to examine the ratings in normals and 2) to examine the scale's validity in the different language and culture. The scale was used in 40 normals and 40 depressives who were matched. Two self-rating scales of depression were administered: the Symptom Rating Test and the Symptom Questionnaire. The results show that the HDRS is a valid measure in that it sensitively discriminates between depressed patients and normals. The findings support Hamilton's view that only the first 17 items of the scale are appropriate for computing the score. The use of self-rating scales yielded additional information. The misclassification rate of the Symptom Rating Test was similar to that of the HDRS. The combined use of Research Diagnostic Criteria (RDC) and HDRS appears to be more reliable for the selection of depressed patients for research than the RDC only.

Life events and depression. A replication.

A study which was first carried out in the United States was repeated in Northern Italy. Life events reported to have occurred 6 months before the onset of illness were compared in 40 outpatients who had a first episode of primary depression, and a matched normal control group. Depressives reported significantly more events than the control groups, and had significantly more of the following: undesirable events, exits from the social field, events which had an 'objective negative impact' (rated as being traumatic) and 'independent events' (events which were unlikely to be a consequence of the depression); the last 2 were judged by a rater who was unaware whether the event had occurred in a depressed patient or in a control subject. There were no significant differences in desirable events, entrances into the social field and events which were within the subjects' control. These findings replicate previous results and are consistent with the view that certain recent life events play a substantial role as precipitants in some depressed patients.

[Reversible cerebral ischemia: psychological reactions to the disease].

Two different psychological tests were applied to 40 patients affected by reversible cerebral ischemic attacks in order to evaluate the presence of depression or neurotic symptoms. 40 normal volunteers were used as a control group. While no statistical differences emerged in the mean values of the control tests, significant psychological impairments were observed in the group of patients. Such psychological disturbances were marked in the series with minor neurological deficits. Similar reactions were noted in subjects still employed and in patients submitted to carotid surgery. The authors emphasize the importance of psychological reactions following organic disease for a better therapy in reversible cerebrovascular disorders.
