Painful unanesthetized arterial puncture may produce transient hyperventilation, and this hyperventilation might alter resting values of arterial pH and PCO2. We investigated this possibility by comparing pH and PCO2 values of blood samples obtained by arterial puncture with values of arterialized venous blood obtained by a painless method. In 19 consecutive subjects, virtually no difference in pH or PCO2 resulted from an arterial puncture that could not be attributed to the inherent precision of the measuring instrument. Mean +/- SEM pH was identical (7.45 +/- 0.05) both before and during an arterial puncture, as was PCO2 (34.4 +/- 1.2 mm Hg). The variation (SD) in PCO2 within an individual subject was +/- 1.7 mm Hg, which was almost identical to the inherent precision of the Radiometer ABL-2 acid base laboratory (SD, +/- 1.32). We conclude that an unanesthetized arterial puncture provides an accurate measurement of resting pH and PCO2.

A visual analogue scale (VAS) and a 4-point scale (FPS) have been compared in patients suffering from prolonged constant pain due to chronic inflammatory or degenerative arthropathy. Each patient was treated with a constant low or high dose of paracetamol or dihydrocodeine throughout a four week period. The VAS was accurate, as reliable and more sensitive than the FPS in registering the intensity of chronic pain. Separate records of each estimate, sealed immediately on completion by the patient, resulted in omission of significantly more pain recordings on the FPS, whereas retention by the patients of their previous records did not systematically influence subsequent judgments. In this study, the VAS appeared to be more satisfactory than the FPS for patient self-rating of pain intensity.

A total of 100 heterosexual adults of either sex with frequent episodes of recurrent genital herpes were allocated to treatment with either Genivir (DIP-253) 1% cream or placebo cream. All patients had genital herpes previously verified by a positive viral culture. The study was carried out as a double-blind parallel group trial. Fifty patients were allocated to each of the two treatment groups. The treatment was initiated within 24 hours after the first sign of a recurrence, and at the pretreatment examination all patients had developed typical lesions with blisters and/or sores. At baseline a sample for herpes virus culture and typing was obtained. The creams were applied four times daily for five days. Follow-up examinations were carried out on days 1, 2, 4 and if needed on days 7, 10 and 14. The major factor used for assessment of efficacy was the time to complete healing of all lesions. Duration of pruritus and pain were also recorded. In the group of patients treated with Genivir cream the time to complete healing was 3.3 days and in the placebo group 6.1 days. The difference was statistically significant (P less than 0.001). The mean duration of pain was 1.3 days in the Genivir group and 2.5 days in the placebo group: this difference also reached significance (P less than 0.01). The duration of pruritus was about the same in both groups. The active agent in Genivir, DIP-253, is a heterocyclic aromatic complex with confirmed anti-herpetic activity and with evidence of a local immunomodulatory effect. It was concluded that the efficacy of topical application of DIP-253 may be due to combined antiviral and immunomodulatory activities.

66 female inpatients with dysfunction pain syndrome, chronic cephalgia and facial pain participated in a randomized, placebo-controlled double-blind study, half the patients receiving a multivitamin preparation for 12 days and the other half a placebo. The biochemically determined vitamin status at the start of the study revealed gaps in the coverage of the vitamin supply, particularly with regard to the vitamins thiamin, riboflavin and folic acid. 65% of the patients showed a subclinical vitamin deficiency of two or more vitamins. With regard to the development of pain during the study no statistically significant differences could be determined, however, between the active-treatment and placebo groups. Nevertheless, a clear reduction in pain was more frequently observed in the active-treatment group, and a deterioration of pain more frequently in the placebo group. A reduction in pain was reported more often by patients in whom the values of alpha-ETK, alpha-EGOT, folic acid and cyanocobalamin improved in the course of the study. Vitamin administration in physiological doses evidently have only weak effects on the behavior of pain; analgesic vitamin effects may be presumed in the case of correspondingly high therapeutic doses for a prolonged period.

From December 1980 to December 1985, 54 patients underwent 56 lower extremity arterial procedures with the use of lesser saphenous vein (LSV) as graft material. LSV was used in all cases because a satisfactory greater saphenous vein (GSV) was unavailable to accomplish the proposed revascularization. Indications for operation were rest pain, ulceration, and gangrene (74%), and 26% had claudication alone. Fifty of the 56 procedures were femorotibial and femoroperoneal bypasses. Three graft combinations were used: LSV alone (29), lesser saphenous vein and other autogenous vein composites (LSV/AUTO) (14), and lesser saphenous vein with synthetic composite grafts (LSV/SYN) (13). Graft patency rates were determined by life-table analysis. The 3-year patency rate for LSV was 60% and for LSV/AUTO was 38%. LSV/SYN graft composites had a graft patency rate at 18 months of 21%. These data suggest that the LSV may function as an autogenous venous graft for lower extremity revascularization when sufficient GSV is not available.

The purpose of this study was to determine whether selected clinical features can distinguish salpingitis associated with endocervical Neisseria gonorrhoeae from that caused by Chlamydia trachomatis in black, inner-city adolescents. We reviewed retrospectively the charts of teenagers presenting to a university hospital outpatient department between January 1982 and January 1984 who were diagnosed as having salpingitis. We included all teenagers who presented with a history of low abdominal pain plus (1) either cervical motion tenderness (n = 15), adnexal tenderness (n = 13), or both (n = 57); and (2) either cervical cultures positive for N. gonorrhoeae and negative for C. trachomatis (n = 31) or cervical cultures negative for N. gonorrhoeae and positive for C. trachomatis (n = 54). Discriminant analysis indicated that the presence of breakthrough vaginal bleeding (standard regression coefficient [SRC] = 0.301; P = 0.023), current usage of oral contraception (SRC = 0.408; P = 0.009), and an elevated erythrocyte sedimentation rate (SRC = 0.522; P = 0.0002) were significantly more often related to the presence of endocervical C. trachomatis. However, we found no significant differences between the two groups for other variables that have been described as distinguishing features (i.e., duration of pain, fever, and leukocyte count).

The effects of 50% nitrous oxide and 50% oxygen and of 30% nitrous oxide and 70% oxygen were evaluated in 88 patients with significant pain while in the prehospital setting. Under the telemetry physicians' supervision, EMT-Ps directed patients in the technique of self-administration of the analgesic gas. Fifty percent (36/72) reported complete or almost complete amelioration of pain; all but 15% (11/72) reported some degree of relief. No patients experienced clinically deleterious side effects, although 48% (41/85) reported side effects, of which 90% were mild. The analgesic properties, lack of complications, quick onset and short duration of action, and acceptance by patients, physicians, and paramedics make N2O a nearly ideal analgesic agent for advanced life support use in the prehospital relief of significant pain.

Risk factors for postcoital bleeding were examined in 475 women who were enrolled in a study of heterosexual transmission of human immunodeficiency virus (HIV). In bivariate analyses, history of sexually transmitted diseases (STDs; P = .03), HIV infection (P = .008), and dyspareunia or pain during intercourse (P = .0001) were significant risk factors. In multivariate analysis, the two latter factors remained significant (for HIV, odds ratio [OR] = 2.1, P = .02, 95% confidence interval [CI] = 1.1-4.0; for dyspareunia, OR = 3.5, P < .001, 95% CI = 1.8-6.6), as did the interaction term of STD history and heavy smoking (OR = 2.4, P = .02, 95% CI = 1.2-5.0). Pain during intercourse was the strongest predictor of postcoital bleeding but may be part of the same phenomenon. Similarly, because this study relied on cross-sectional data, the direction of the causal pathway linking HIV to postcoital bleeding cannot be established. However, these data suggest that smoking, a modifiable risk factor, may increase risk of postcoital bleeding and contribute to susceptibility for HIV and other STDs.

To investigate whether the addition of epinephrine would enhance postoperative pain relief by intrathecal morphine, we studied 36 patients scheduled to have spinal anesthesia for gynecologic surgery. Patients were randomly allocated to one of three groups: the first received epinephrine 0.12 mg, morphine 0.2 mg, and hyperbaric tetracaine 12 mg intrathecally (EMT group, n = 11); the second received morphine 0.2 mg and hyperbaric tetracaine 12 mg intrathecally (MT group, n = 13); and the third received epinephrine 0.12 mg and hyperbaric tetracaine 12 mg intrathecally (ET group, n = 12). The time to the first request for supplemental analgesics was longest (2182 +/- 251 min, mean +/- SEM) and the injection number of supplemental analgesics was least in the EMT group (P < 0.05). The percentage of patients who received supplemental analgesics in the EMT group (45.5%) was less than the other two groups (P < 0.05). Six patients in the EMT group and one in the MT group needed no additional analgesics during 48 h (P < 0.05 versus the MT and ET groups). The visual analog scale (VAS) pain score was larger in the ET group than the EMT group (P < 0.05), but was similar in the EMT and MT groups. There were no differences among groups in the incidence of nausea and pruritus. Our data show that the addition of epinephrine enhances postoperative analgesia by intrathecal morphine without increasing the incidence of adverse effects as compared with intrathecal morphine alone.

This is a retrospective review of 279 pelvic ultrasound examinations requested over 19 months by a department of GU medicine. An abnormal ultrasound was rarely seen in women with pain but no pelvic mass (16%). If a mass was found on bimanual palpation, the yield of abnormal ultrasound was much higher (52%). Pelvic ultrasound was also useful in refuting a diagnosis of ectopic pregnancy by demonstrating an intrauterine gestational sac.
