Stress in families of HIV-positive children living in south Texas.

The purpose was to conduct a pilot study of the extent of stress and differences in sources of stress experienced by HIV+ and HIV- caregivers of HIV+ children living in South Texas. 13 infected and 9 uninfected caregivers each completed the Questionnaire on Resources and Stress for their preschool-aged HIV+ child. Both HIV+ and HIV- caregivers experienced clinically significant stress. HIV+ caregivers reported that relative to the HIV- group, they perceived themselves to be in poorer physical or emotional health, to receive less social support from others, and to be less pessimistic about the future of their child or family.

An evaluation of two primary care interventions for alcohol abuse among Mexican-American patients.

AIMS: This study examined the effects of two primary care interventions (a physician intervention and a clinic-based psychoeducational group) on drinking patterns, psychosocial problems and blood test results (MCV, GGT, SGOT and SGPT). DESIGN: Subjects were randomized into one of four treatment groups: physician intervention, psychoeducation, both interventions, or no intervention. Follow-up data were collected at 12 and 18 months. SETTING: Subjects were recruited from a family practice outpatient clinic managed by a public hospital. PARTICIPANTS: Included 175 Mexican-American female and male primary care patients who screened positive for alcohol abuse or dependence. These patients were not seeking help for alcohol problems. INTERVENTIONS: Included a brief physician intervention and a 6-week patient psychoeducational group. MEASUREMENTS: The Diagnostic Interview Schedule assessed subjects for alcohol abuse; the Addiction Severity Index measured alcohol-related problems, including psychosocial issues. FINDINGS: All four treatment groups demonstrated significant improvement over time, with few differences between intervention and control groups. CONCLUSIONS: Assessment can be confounded with brief interventions; future investigators should use non-assessed control groups.

[Sensory stimuli in the reproductive function].

There is very ancient evidence that sensory systems and specific stimuli affect reproductive functions. Studies of the reproductive cycles and behavior led to the concept that simuli acting through the nervous system could affect the endocrine system. The event which normally induces the milk ejection reflex is stimulation of the teat; however under certain conditions the reflex can be provoked by other sensory stimuli as the sound of other rats nursing their litters. The endocrine mechanisms involved in the termination of pregnancy in rats seem to be essential for the occurrence of parturition, the expression of maternal behavior and lactation. Ovariectomy performed on day 20 of pregnancy impaired parturition, maternal behavior and lactation. Treatment with estrogen permitted normal delivery, maternal response and lactation only when the hormone was injected immediately after ovariectomy. Estrogen administered the day after was not effective. The administration of progesterone to ovariectomized pregnant rats prevented parturition. Maternal behavior did not occur in ovariectomized-progesterone treated rats when delivery was induced by Caesarean section on day 22 of pregnancy. The association of a progesterone decrease and a simultaneous estrogen secretion is an important step for normal parturition, maternal behavior appearance and normal lactation. After parturition a progressive increase in circulating progesterone seems to "adapt" the C.N.S. to the steroid which may modulate the release of prolactin induced by suckling. An acute increase of the progesterone level by s.c. silastic implant or injection during the first 3 or 6 days following parturition impairs the normal growth of the litter probably by impairing milk secretion and milk ejection. Prolactin release was significantly diminished by the progesterone treatment. Pretreatment with an antiestrogen potentiates the inhibitory effect of progesterone on litter growth.(ABSTRACT TRUNCATED AT 250 WORDS)
