Neutron scattering cross sections and partial kerma values for oxygen, nitrogen and calcium at 18 less than En less than 60 MeV.

Recent measurements of differential elastic and inelastic neutron scattering from oxygen, nitrogen and calcium at 18 less than En less than 26 MeV are presented and analysed in terms of the optical model. These data, together with earlier measurements of scattering and total cross sections, are used to construct model potentials that may be used to calculate various quantities of interest in neutron dosimetry in an energy region (20-60 MeV) where very few cross section data are available. The heavy-ion-recoil contribution to kerma is obtained directly from the data at each energy. The value of proton inelastic scattering data for validating potential models at high energy is discussed.

[The Othello syndrome].

A case is described and 7 others are discussed of the Othello Syndrome, characterized by cognitive, affective and conative manifestations plus non-specific psychosomatic accesory symptoms. The nuclear symptom is the delusional or delusion-like idea of jealousy. The syndrome is seen in both sexes, as part of a number of clinical entities (paranoia, psychoses, organic brain syndromes, neuroses and personality disorders). Premorbid personality and family history are always abnormal. Cases of cocaine abuse, involutional melancholia and borderline syndrome are remarkers. The management of this syndrome and of its social sequelae is emphasized.

[Community psychiatry in Latin America].

Present trends of communitary Psychiatry are considered, with an assessment of their measurable parameters and degrees of feasibility. Three models are set forth, taking into account their principal factors: primary mental health agents, actual resources, socio-political structures, geographical setting, cultural patterns, possible strategies, and community participation. Model I is a traditional one, it relies on decisions taken from the administration, which endows both scientific authority and normative power. Participation of the community is not called for, and has neither a place nor a function. The stress is on secondary and tertiary prevention. Model II is more focused on community needs and primary prevention. Programs are conceived after the community is consulted. They use primarily the health efectors within the community itself. Model III stresses active participation of community leaders and members at all levels of decision, and implementation, as well as the use of community's own resources for promoting health. Assistential centers and personnel are only the specialized supports and supervisors of actions, mainly carried out by the protagonists themselves. All three models are analyzed from several standpoints, including theoretical conception, feasbility of implementation, efficacity, vulnerability, cost-benefit ratios and foreseeable outlooks.
