[Influence of social support on patients with essential hypertension].

OBJECTIVE: To determine whether social support affects blood pressure control in patients diagnosed with essential Hypertension. DESIGN: Observational, prospective study, with a year's follow-up. SERRING: Mariñamansa-A Cuña Health Centre, Ourense (Galicia), Spain. PARTICIPANTS: 236 patients diagnosed with essential hypertension in health centre controls. MEASUREMENTS: During the one-year follow-up the following clinical variables were measured: age, sex, blood pressure, severity of hypertension, tobacco consumption, alcohol consumption, presence of diabetes mellitus, hypercholesterolaemia, Body Mass Index and compliance with treatment. Social and family variables were: marital status, cultural level, economic and social status, type of family, stressful vital events and social support. RESULTS: Mean age was 63.51 (62.05-64.96); 66.1% were women. Predominant kind of family was nuclear (64.3%). 30.2% had low social network (0-1 social contacts). We found 22% poor functional social support. Social support remained stable throughout the study. Hypertense patients with poor social networks had, after control for possible confusing variables, their systolic pressure 9.59 mm Hg (2.6716,51) and diastolic pressure 4.29 mm Hg (0.448.15) higher than hypertense patients with broader social networks. CONCLUSION: Hypertense patients with a poor social network had higher blood pressure figures than hypertense patients with wider social networks.

[Cryotherapy with nitrous oxide in primary care].

OBJECTIVE: To study the efficacy, tolerance and safety in primary care of the cryotherapy technique using nitrous oxide. Design. Descriptive, observational and transversal study. SETTING: Mariñamansa-A Cuña Health Centre, Ourense. PARTICIPANTS: All the patients who consulted for cutaneous lesions caused by cryotherapy between March and April 2000 (n=130). MAIN MEASUREMENTS: Age, sex, diagnosis, location, size of lesion, duration of application of the cryogenic agent, previous treatment, side-effects observed, and evolution of the lesion. RESULTS: Mean age was 36.65 (95% CI, 32.57-40.74), of whom 53.8% (95% CI, 44.80-62.50) were women. The most common lesions were common warts (68.5%), actinic Keratosis (12.3%) and plantar warts (7.7%). We found that most lesions were located on an upper limb (50.8%). The mean size of lesions was 8.65 mm2 (95% CI, 4.50-12.80). 69.7% of warts were scraped prior to cryotherapy; and 16.2% received prior keratolysis. We found no side-effects in 32.3% of the patients; the commonest side-effect detected was blisters. Mean number of cryotherapy sessions was 2.82 (95% CI, 2.39-3.29). The technique was tolerated well in 83.8% of cases. We found total cure in 87.7%. Most of the cutaneous lesions that failed were common warts. CONCLUSIONS: Nitrous oxide is effective in most lesions caused by cryotherapy. The technique is tolerated well, can be handled easily and can be used in primary care.

[Environmental stress and cardiovascular reactivity: the effect of stressful life events on hypertense patients].

OBJECTIVE: To assess the effect of stressful life events (SLE) on the monitoring of patients with essential hypertension. DESIGN: Observational and prospective. SETTING: Primary care. PARTICIPANTS: 236 hypertense patients selected by systematic randomised sampling. MEASUREMENTS: Age, sex, marital status, cultural level, kind of family, presence of SLE, social support, blood pressure, severity of hypertension, tobacco consumption, alcohol, presence of diabetes, hypercholesterolaemia, body mass index, compliance with hypertension treatment. RESULTS. Mean age was 63.51 (62.05; 64.96), with 66.1% being women and 33.9% men. 48.7% of the patients referred to some SLE during the follow-up. These reached a mean of 47.65 (33.16; 62.15) life change units (LCU). Patients with high-impact SLE (>150 LCU) had a significant increase of 10.91 mm Hg (0.43; 21.40) in their systolic blood pressure and of 9.48 beats per minute (3.78; 15.19) in their heart rate, after monitoring for possible factors of confusion. We observed a similar trend for diastolic pressure, but this did not reach statistical significance. CONCLUSION: The presence of SLE has a negative effect on systolic blood pressure in hypertense patients.

[Comparison of family physicians' and gynecologists' use of the intrauterine device (IUD)].

OBJECTIVE: To quantify differences between general practitioners (GPs) and gynaecologists in the technique of insertion and follow-up of the intra-uterine device (IUD). DESIGN: Multicentred, descriptive, longitudinal study. SETTING: Two urban health centres and a family guidance clinic. PARTICIPANTS: Target population (n = 1700) between January 1993 and January 1996. Estimated mean of complications was 25%. Sample size was 247 for alpha = 0.05 and 1-alpha = 0.95. The sample was extended to 300 to allow for possible losses of files, estimated at 20%. MEASUREMENTS AND MAIN RESULTS: The variables age, sex, marital status, educational level, parity, abortions, previous contraception, type of job, type of IUD, post-insertion and follow-up complications, subjective evaluation, removal and average follow-up time, were analysed. 158 (54.9%) of the 288 IUDs finally studied were inserted by GPs, and 130 (45.1%) by gynaecologists. 69.5% were anchor-shaped, and 30.5% T-shaped. In 85.5% no immediate complications were found. Mean follow-up time was 22.67 months (CI 95%, 21.3-24.0), during which time 36.6% had complications detected, which led to removal of the device in 22.3% of complications. We found no statistically significant differences between the two populations for age, marital status, subjective evaluation, number of abortions, parity or previous contraception. Likewise, no differences between G.P.s and gynaecologists were detected for post-insertion or follow-up complications, percentage of IUDs removed, or period of time evaluated. There were differences found for the type of IUD used, with more anchor-shaped IUDs in primary care. There were no differences for the type of IUD or complications requiring its removal. CONCLUSIONS: In the population studied we found no differences in immediate or later complications between IUDs inserted by GPs and by gynaecologists.

[Validation of the chronometer test as a method of screening for hypoacusis in patients aged 65 years and older].

OBJECTIVE: Evaluation of the chronometry test as a screening procedure for hypoacusia compared with tonal audiometry, in patients over 65 years. DESIGN: Cross-sectional study. SETTING: Mariañamansa health area (Ourense). PATIENTS: The first 49 patients over 65 who came to the medical consultations in June and July 1992 were selected, irrespective of the reasons for their visit; there were 17 males and 32 females, with and average age of 72.4 +/- 4.6 and 71.9 +/- 4.5. Only one patients consulted directly about loss of hearing. MEASUREMENTS AND MAIN RESULTS: A statistically significant association was found between the chronometry test and the audiometry test (gold-standard), significant at p < 0.005 for the left ear and p < 0.05 for the right ear. The test achieved a sensitivity of 0.85 and specificity of 0.76 in the case of the left ear, and 0.84 (sensitivity) and 0.56 (specificity) for the right ear. The kappa rate was 0.55 for the right ear and 0.67 for the left ear, showing agreement that went well beyond chance. CONCLUSIONS: In our view, the chronometry test constitutes an cheap, effective, simple, and replicable procedure for the detection of hypoacusia in patients aged over 65, and one which can usefully be used when no audioscope is available.

[Urethral duplication: apropos a case].

We report a case of dorsal blind-ending urethral duplicity in a 37-year-old male who presented dysuria and occasional mucopurulent discharge. The presumptive diagnosis was made on the findings at physical examination and was corroborated by retrograde urethrography. The patient was treated conservatively because the symptoms were minimal.
