Therapeutic strategies and outcomes: perspectives from different cultures.

Two forms of psychological therapy, one Japanese the other Euro/American, are described and compared. It is suggested that each identifies comparable goals for individual change. However, each differs in the means by which change is induced. The consensus concerning goals is taken as evidence of universal values in the definition of the fully functioning self. However, the divergence in means by which these goals are attained reflects specific cultural differences. The implications of these differences are related to individualistic versus relational values within the cultures discussed. It is proposed that the comparisons have implications for the practice of any specific form of psychotherapy on members of a culture other than that within which the therapy has developed.

Juvenile xanthogranuloma of the corneoscleral limbus.

Juvenile xanthogranuloma presenting as an isolated corneoscleral lesion is rare. We report such a case in a 5-year-old boy who required lamellar sclerokeratectomy to the level of Descemet's membrane. Ten months after treatment by total excision and lamellar corneoscleral grafting with donor tissue there was no evidence of recurrence. We discuss the clinical and histologic features of this disorder, the differential diagnosis and treatment options.

Rhinoplasty and the nasolabial area.

The nasolabial area is important to consider in achieving a satisfactory relationship between the nose and the other features of the face; this will result in a natural-looking nose. However, the importance of the entire nose on a particular face should be kept foremost in mind.

Nasal tip projection: counterpoint.

The achievement of tip projection in rhinoplasty has been overemphasized in recent programs and publications. The normal spring support of the tip by the medial crura will ordinarily give adequate tip projection in a well-executed rhinoplasty. If additional tip projection is required, the simplest procedures are advancement of the columella and tip upward on the end of the septum and similar advancement of the alar cartilages toward the bridge. For additional support, a cartilage strut is inserted between the medial crura. Retrusion of the distal nasal complex requires maxillary advancement or support beneath the base of the alae and columella. If a tip graft is required, one achieves a more natural tip by a posterior conchal graft, utilizing its natural curve, rather than by a building-block support.

International labour migration and uneven regional development in labour exporting countries.

"International labour migration involves 20 million workers from 'middle income' and 'Third World' countries. The article reviews both theoretical propositions and empirical evidence on its effects on regional disparities in labour exporting countries. It shows the variety of ways in which the departure of emigrants affects the uneven development of rural and urban areas there by changing the volume and nature of production as well as welfare conditions. Regional patterns of production and welfare are further modified by the impact of emigrants' remittances and their eventual return."

Multiple-tiered deep support of cheeks in meloplasty and rhytidectomy.

Maintaining satisfactory long-term results in a face-lift on an aging face is an important aspect of facial plastic surgery. While undermining and support of the SMAS in the posterior cheek has achieved recent popularity, plication of the fascia in the cheeks has been at least equally effective and safer. Variations of this technique have been used for 30 years with satisfactory results.

A method of direct eyebrow lift.

A very simple procedure, requiring about twenty minutes, accomplishes moderate elevation and support of the eyebrows. It may be utilized for eyebrow ptosis alone, whether unilateral or bilateral; in conjunction with meloplasty and blepharoplasty; for equalizing asymmetrical eyebrows, and for further support of markedly ptotic upper lids. It has been used by the author in instances of partial and complete facial paralysis in conjunction with other procedures about the face to accomplish better symmetry. The duration of results with this procedure varies with tissue quality and healing, surgical technique, care given the area during healing by the patient, amount of frowning and vigorous facial muscle use by the patient, and aging. It is a useful adjunct, especially when used for moderate or subtle brow lifts.

Monoclonal antibodies showing sequence specificity in their interaction with single-stranded DNAs.

Six hybridoma cell lines which secrete monoclonal antibodies binding to nucleic acids were produced from autoimmune NZB/NZW mice. Four of the antibodies were IgG's and the other two were IgM's. Using a solid phase radioimmunoassay (SPRIA) the binding of the antibodies to over thirty different nucleic acids was estimated. All the antibodies were extremely specific. There was no detectable interaction with various RNAs, and single-stranded DNAs bound more antibodies than duplex or multi-stranded DNAs. In every case the antibodies also showed considerable sequence preferences. For example one monoclonal antibody bound to d(TTC)n but not to d(TCC)n while another interacted strongly with D(TG)n and d(CA)n but not with d(TC)n, d(GA)n or homopolymers. In other cases the patterns of sequence specificity were extremely difficult to interpret although it seems clear that monoclonal antibodies have the potential to distinguish between any two nucleic acids however similar.
