Suicide attempts of high medical seriousness in schizophrenic patients.
A retrospective study was conducted that included all patients who in the previous 6 years had required admission to our hospital for medical reasons following attempted suicide (N = 253). Those diagnosed as schizophrenic (n = 43) in accordance with DSM-III-R criteria were compared with the other nonschizophrenic suicide attempters. Schizophrenic patients were significantly different in that they were younger and generally unmarried, usually used violent methods, made more attempts while in a psychiatric center, and presented a lower incidence of concurrent organic illness than the nonschizophrenics; almost all of them were chronic. A large majority (80%) showed delusional and hallucinatory symptoms at the time of the attempt. In contrast, depressive symptoms were noted in an appreciably lower percentage of subjects than that in other studies of suicidal behavior in schizophrenics.

Natural Leishmania infection of Lutzomyia spp. in Peru.
Natural infection of Lutzomyia spp. with Leishmania was studied with the aid of the polymerase chain reaction (PCR) in Chaute, Lima, Perú, a locality endemic for Andean cutaneous leishmaniasis (uta). The PCR, with primers specific for the L. braziliensis complex, was applied to sandfly pools. Sandflies were sampled from April 1990 to May 1991 with CDC light traps in homes, and from near homes with a Shannon trap using protected human bait. Lu. verrucarum (4 pools) and Lu. peruenis (2 pools) from the anthropophilic collections, and Lu. verrucarum (2 pools) from indoors were found to be infected with Leishmania. The majority of infected sandflies were recorded mainly in April 1991 (4 pools), coinciding with the highest sandfly densities and the maximum number of new cases of uta (7). Non-infected sandflies were found from May to October 1990 and January to March 1991. Thus, these 2 sandfly species play a role in the spread of leishmaniasis among humans and other animals in Chaute.

Differential features between bipolar I and bipolar II disorder.
Although bipolar II disorder is generally viewed as a mild form of classic manic-depressive illness, recent investigations suggest that it could be a valid diagnostic category different from bipolar I in genetic, biological, clinical, and pharmacological aspects. Twenty-two patients fulfilling Research Diagnostic Criteria for the diagnosis of bipolar II disorder and 38 bipolar I patients were evaluated with the Schedule for Affective Disorders and Schizophrenia by two independent interviewers and compared. Bipolar II patients had significantly more previous episodes (P = .001), including both depressive (P = .003) and hypomanic (P = .006) switches, but had been hospitalized (P = .001) and presented psychotic symptoms (P < .001) less frequently. These results suggest that bipolar II disorder is less severe than bipolar I with regard to symptom intensity, but is more severe with respect to episode frequency.

[Bipolar II disorder: course and suicidal behavior].
INTRODUCTION: Bipolar II disorder seems to be more than a mild form of classic manic-depressive illness. Differences with bipolar I concern genetic, biological, clinical and pharmacological aspects. Nevertheless, studies on suicidal behavior in both groups have resulted in inconsistent results PATIENTS AND METHOD: Twenty-two patients fulfilling Research Diagnostic Criteria for the diagnosis of bipolar II disorder and 38 bipolar I were evaluated with the Schedule for Affective Disorders and Schizophrenia by two independent interviewers, and compared. RESULTS: Bipolar II patients had significantly more previous episodes (p = 0.001), including both depressive (p = 0.003) and hypomanic switches (p = 0.006), but had been hospitalized (p = 0.001) and presented psychotic symptoms (p < 0.001) less frequently. CONCLUSIONS: There were no significant differences between both groups regarding suicidal behavior variables. These results suggest that bipolar II disorder is less severe than bipolar I regarding symptoms intensity, but more severe with respect to episodes frequency, and that suicide attempts rates are not useful to discriminate between both groups.
