The effect of brushing on hair loss in women.

BACKGROUND: Hair loss is a common, bothersome problem among women. OBJECTIVE: To evaluate the effect of different brushing frequencies on hair loss in women. METHODS: This was a non-randomized crossover study. During a 4-week period, 14 women were asked to brush their hair with different frequencies during each of the 4 weeks. The amount of hairs lost during each week was counted and the average hairs lost during each week was compared with that of a week with a different brushing frequency. RESULTS: In all comparisons analyzed, hair loss was reduced by reducing brushing frequency. A subgroup analysis found strong association (p < 0.05) between brushing frequencies and the magnitude of hair loss. A limitation of the study was that the majority of the subgroup analyses did not find a statistically significant association between brushing frequency and amount of hair lost. CONCLUSION: Brushing is associated with hair loss. Reducing the brushing frequencies may reduce the amount of hair shed.

Breast cancer and psychological distress: mothers' and daughters' traumatic experiences.

GOAL OF WORK: The objective of this exploratory retrospective study was to assess the effects of breast cancer diagnosis upon the psychological distress of adult breast cancer patients and their mothers, particularly mothers who experienced past trauma. MATERIALS AND METHODS: Four groups of mother-daughter dyads were evaluated using self-reporting measures of psychological distress [Brief Symptom Inventory (BSI)], familial support (PFS), and adjustment to cancer (MAC, IES): breast cancer patients whose mothers were Holocaust survivors (group 1), breast cancer patients with non-traumatized mothers (group 2), healthy daughters of Holocaust survivor mothers (group 3), and a control group of healthy daughters with non-traumatized mothers (group 4). MAIN RESULTS: Distress levels of both mothers and daughters in group 1 were significantly higher than distress levels of mothers and daughters in the other three groups. Daughters' distress levels in all four groups were found to be significantly related to mothers' distress levels, with the highest correlation found in both groups of cancer patients. The factors of having a clinically distressed mother and being a second-generation daughter contributed the most to predicting the clinical distress of the daughter. CONCLUSIONS: The outcomes imply that the mother's traumatic past intensifies the distressing effect of cancer diagnosis upon both the patient and her mother. The findings concerning the impact of cancer diagnosis upon the patients' non-traumatized mothers were more ambiguous. The results support the idea that in the case of breast cancer patients, a complete psychological evaluation must include not only spouses and children but also the familial background of the patient and the history of the patients' mothers.

Psychological distress and coping in breast cancer patients and healthy women whose parents survived the Holocaust.

Psychological distress levels of breast cancer patients whose parents were Holocaust survivors ('second-generation Holocaust' patients) were previously shown to be significantly higher than those of a matched group of patients with non-traumatized parents. In this study, we investigated whether this effect reflects only the generally higher distress levels of second-generation Holocaust women or whether breast cancer patients with traumatized parents also present lower adaptation abilities, which result in increased distress to the breast cancer diagnosis. We assessed psychological distress and measures of coping in 193 second-generation Holocaust patients diagnosed with breast cancer, 164 breast cancer patients with non-traumatized parents, 176 healthy second-generation Holocaust women, and 143 healthy women with non-traumatized parents. The main effect of cancer and the main effect of second-generation Holocaust survivor on psychological distress were found to be significant. These two factors (cancer x second generation) had a synergistic effect on the levels of depression and psychoticism. These results support the hypothesis that, at least on some psychological measures, the cumulative distressing effect of having traumatized parents and breast cancer diagnosis is higher than the effect of each factor alone.

Iontophoresis-gentamicin delivery into the rabbit cornea, using a hydrogel delivery probe.

PURPOSE: To evaluate the efficacy of penetration of gentamicin into the cornea of rabbits using iontophoresis with a hydrogel-gentamicin containing probe. METHODS: Eight of 10 groups (groups 3-10) of 6 rabbits (one eye per rabbit), underwent corneal iontophoresis using soft stable hydroxyethyl methacrylate hydrogel discs (80% water content) loaded with gentamicin sulphate which were mounted on an iontophoresis probe. The studied current intensities were 0, 0.1, 0.3 and 0.6 mAmp, and the durations of iontophoresis were 10 and 60 sec. Two control groups received 1.4% topical drops of gentamicin every 5 min for 1 hr (group 1) or sub-conjunctival injection of 10 mg gentamicin (group 2). Following sacrifice, aqueous humour was taken, corneas were excised, and gentamicin concentration was determined in aqueous humour and cornea samples. RESULTS: Post-iontophoresis, the concentration of gentamicin in the corneas ranged from high (88.60 +/- 38.64 microg ml(-1)) to very low (0.10 +/- 0.89 microg ml(-1)). Both the control groups and those rabbits treated with current intensity of 0.1 mAmp or greater obtained therapeutic gentamicin levels in the corneas. Use of iontophoresis for 60 sec or current intensity greater than 0.1 mAmp obtained corneal gentamicin levels not different from sub-conjunctival injection. Application of current intensity of 0.1 mAmp or greater gave corneal gentamicin concentrations comparable to topical application of the drug, except when 0.6 mAmp were used for 60 sec (p = 0.05). Increasing current intensity or duration of iontophoresis significantly increased (p = 0.001 for both) gentamicin penetration into the cornea. Current intensity had more influence (Beta2 = 0.40) than duration (Beta2 = 0.13) on drug penetration. A significant interaction was found between the duration of iontophoresis and the current intensity. Very small or no concentrations of the drug were discovered in the anterior chambers of rabbits. CONCLUSIONS: Iontophoresis using hydrogel-gentamicin probe may deliver therapeutic concentrations of gentamicin into the cornea.

Is perceived family support a relevant variable in psychological distress?. A sample of prostate and breast cancer couples.

OBJECTIVE: In this cross-sectional pilot study of couples in whom the man was diagnosed with prostate cancer or the woman with breast cancer, the purpose was to identify and compare the variables that characterize couples where both spouses are in high psychological distress with couples where the psychological distress of both spouses is within the normal range. METHODS: Psychological distress and perception of family support in 574 individuals (118 consecutive prostate cancer patients and their spouses, and 169 randomly selected breast cancer patients and their spouses) were assessed using the Brief Symptom Inventory (BSI) and the Perceived Family Support (PFS) self-report questionnaires. RESULTS: Couples experiencing high psychological distress reported lower levels of perceived family support than couples in whom both spouses reported normal levels of psychological distress. CONCLUSION: The findings support the notion that perceived family support is associated with the psychological distress in both patients and spouses.
