Genetic studies in the Markham Valley, northeastern Papua New Guinea: gamma globulin (Gm and Inv), group specific component (Gc) and ceruloplasmin (Cp) typing.

Genetic studies in the Markham Valley, northeastern Papua New Guinea; Gamma globulin (Gm and Inv), group specific component (Gc) and ceruloplasmin (Cp) typing. M. S. Schanfield, Eugene Giles and H. Gershowitz, Department of Human Genetics, University of Michigan, Ann Arbor, Michigan 48104. Immunoglobulin allotyping was carried out on 680 serum samples from inhabitants of the Markham Valley, Papua New Guinea (seven villages speaking the same Melanesian [PAP] speaking village). Family and population data verified the presence of Gm-ag, G-ab and Gm-afb among the MN speakers and Gm-ag, Gm-axg, Gm-ab and Gm-afb among the PAP speakers. The frequency of Gm-ag was between 0.048 and 0.235, while the frequency of Gm-ab was between 0.427 and 0.627 and the frequency of Gm-afb ranged between 0.261 and 0.424 among the seven MN villages; the single PAP village had frequencies of 0.568, 0.160, 0.213 and 0.059 for Gm-ag, Gm-axg, Gm-ab and Gm-afb respectively. The frequency of Inv1 ranged between 0.034 and 0.095 in the MN villages and 0.014 in the PAP village. The rare occurrence of Gm(x) without Gm(g) was explained by the presence of a Gm-axfb haplotype, while in two PAP families the presence of Gm(x) without Gm(g) was explained by the abnormally weak expression of Gm(g) in a Gm-axg haplotype. A total of 654 sera were typed for Gc, with the seven MN villages ranging between 0.350 and 0.650 for Gc-1, 0.312 and 0.575 for Gc-2 and between 0.017 and 0.112 for Gc-Ab; the single PAP village had a value of 0.627 for Gc-1, 0.165 for Gc-2 and 0.208 for Gc-Ab. A total of 693 sera were tested for ceruloplasmin type. All showed the common Cp(b) phenotype.

Gammaglobulin factors (Gm and Inv) in New Guinea: anthropological significance.

Analysis of the hereditary Gm and Inv gamma-globulin factors of 1669 New Guineans from the Morobe and Eastern Highlands districts and Bougainville Island demonstrates thatthe frequencies of the three Gm alleles present (Gm(a), GM(ab), and Gm(ax)) are similar in general to those in Mongoloids and in particular to those in Southeast Asians and Micronesians. The New Guinea frequencies are distinct from those in other populations, including Australian aborigines. Highly significant differences in frequencies of Gm and Inv alleles occur between Melanesian-and non-Austronesian-speaking New Guineans.

[Risperidone in the treatment of psychotic, affective and behavioral symptoms associated to Alzheimer's disease].

INTRODUCTION: A total of 235 patients with diagnoses of Alzheimer's dementia together with psychotic and/or affective symptomatology, as well as behavioral disturbances was included in an open label postmarketing surveillance study. The study objectives were to asses: 1) risperidone efficiency in psychotic and affective symptomatology and behavioral disturbances; 2) risperidone influence in the patient's performance, 3) dosage range at which efficiency is observed; and 4) safety in this group of patients. Patients were observed during a six month period. Risperidone was used at a mean dosage of 1.23 +/- 0.86 mg daily (range: 0.5-4.5 mg daily). MATERIAL AND METHODS: Risperidone was assessed by the Clinical Global Impression (CGI), Geriatric Depression Scale (GDS), Neuropsychiatric Inventory (NPI), Clinical Deterioration Rating (CDR), UKU subscale for neurological side effects and spontaneous reports. Patients were evaluated at baseline, 15 days and months 1, 2, 4 and 6. Sixteen patients (6.8%) were excluded from the statistical analysis due to protocol violation. Fifty four patients (24.7%) dropped out. RESULTS: Risperidone produced a significant improvement in the mean total scores of CGI, NPI, GDS (patient's satisfaction, hope.) and CDR (judgment and problem solving, community affairs, hobbies.) scales. Extrapyramidal symptoms improved from day 15 onwards in patients who had received antipsychotic treatment previously; in naive treated patients these symptoms did not change during the study period. CONCLUSIONS: Risperidone was well tolerated. Only 6 (2. 7%) discontinued treatment due to adverse events. Ninety seven percent of the patients did not suffer any adverse event; the resting 2.7% suffered one or more side effects: sedation (1.4%), constipation (0.5%) and vomiting (0.5%) among others.
