An epidemic of Lyme borreliosis on Hokkaido island, Japan, was surveyed by questionnaire in 587 hunters. The 308 returns (52.4%) revealed episodes of tick bite (usually 2 or more) in 210 cases. Skin rashes appeared in 164 cases. Associated itching, pain, etc., but not skin rash, were more frequent after 2 or more tick bite. Previous determinations of anti-Borrelia burgdorferi antibody titers in these subjects and in controls suggested an association with outdoor activities other than hunting, and among 33 cases of dermatological symptoms and 23 of articular symptoms, 4 and 2, respectively, were antibody-positive. Most of these antibody-positive subjects had suffered tick bite at least twice, but had had no antibiotic treatment. Three subjects with joint disorders were antibody-positive. These findings suggested that the many hunters exposed to Borrelia burgdorferi frequently carried latent infections, and that some had latent form of arthritis, dermatitis and other disorders.

It is well known that cutaneous pain causes c-fos gene expression in the dorsal horn neurons. The present study examined whether or not an itching sensation had the same effect on these neurons. In order to produce an itching sensation, cotton balls soaked in histamine solutions of different concentrations were applied to the lower limbs of rats and then the treated area was scratched with the tip of a pair of forceps. After 2 h, the number of neurons showing Fos-like immunoreactivity was significantly increased in a dose-dependent manner in the ipsilateral dorsal horn when compared to saline-treated and scratched controls. When scratching with the forceps was omitted, the number of these neurons was reduced to one-third, but was still significantly higher than in controls treated only with saline. Expression of Fos-like immunoreactivity in these animals was markedly reduced by morphine pretreatment (10 mg/kg, i.p.), suggesting that the transmission of both itch and pain is blocked by morphine.

The safety and efficacy of patient-controlled analgesia used for postoperative pain relief were evaluated. Cumulative 24-hour requirements were analyzed for possible correlation with patient characteristics. All patients who used a patient-controlled analgesia device for postoperative pain relief were reviewed from June to October 1991. The device Baxter's basal/bolus infusor with patient control module, was used to deliver fentanyl in 379 patients. The fentanyl requirement, verbal analog pain score, first passage of flatus, side effects, sedative score, and degree of satisfaction were examined. The fentanyl requirement during the first 24 hours after operation was analyzed with regard to age, body weight, and sex. The daily fentanyl consumption in the first three postoperative days was 928 +/- 352 micrograms (n = 338), 553 +/- 259 micrograms (n = 220), and 490 +/- 222 micrograms (n = 71), respectively. The requirement for fentanyl during the first 24 hours after surgery was significantly higher than for the next two days (p-value < 0.001). Fentanyl consumption correlated well with body weight, and inversely with age. No difference was found between fentanyl consumption and sex (p-value = 0.4687). The mean time to the first passage of flatus in patients with abdominal surgery was 54.6 +/- 26.4 hours. The incidence of nausea, vomiting, and dizziness was similar, about 20% of patients. Itching was noted in 7% of patients. Oversedation (class 4) was found in three patients during the first operative day, the sedative score for other patients were around class 1-3. No patient exhibited signs of respiratory depression or withdrawal syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

Adverse effects of opioids are multiple. They are most often receptor-mediated and inseparable from their desired effects. The most severe mishaps with opioids are related to their respiratory depressant effect, which is widely influenced by factors such as pain, previous opioid experience and awareness. Other relevant central nervous system effects of opioids include cough suppression, nausea and vomiting, rigidity, pruritus and miosis. The cardiovascular adverse effects of opioids are mainly related to histamine release and differ widely between agonists and agonist-antagonists. Gastrointestinal effects such as constipation, reflux and spasms of the bile duct are well described. Adverse effects on endocrine, immunological and haematological functions are possible, while allergic reactions are extremely rare. The adverse effects of long term use are overestimated. Systemic toxicity is negligible and development of tolerance is minimal while treating pain. In the clinical setting of pain control, addiction and withdrawal do not pose significant problems. Nevertheless, the possible effects of opioids on the unborn child should always be considered. Overall, opioids show a good record of safety. Their use should not be unduly limited by unfounded fears of adverse effects, but these effects should be avoided by anticipation and prevention.

Treatment with rHuEpo can eliminate many symptoms that had been attributed to uremia. Repetitive punctures in children undergoing three times weekly subcutaneous (SC) rHuEpo can result in noncompliance with the therapeutic regimen. The aim of this study was to evaluate the efficacy of once weekly SC injection of rHuEpo in children with end-stage renal disease (ESRD) on CAPD. Six children (5 males, 1 female, mean-age: 6.0 years, range: 0.5 to 15.8 years) with ESRD on CAPD were treated with a regimen of rHuEpo 150 U/Kg/week SC for 12 weeks. All patients received oral iron supplementation. All children had improved appetite and well-being. The adolescents showed an increased ability to engage in regular activities. The hematocrit increased from 20.3 +/- 1.2% to 31.7 +/- 3.8% in 12 weeks. The mean weekly increase in hematocrit was 0.95 +/- 0.34%. There was no significant differences in iron indice prior to and during rHuEPO treatment. Side effects related to rHuEpo included transient pain at the site of injection in all, pruritus at the site of injection in 1 child, hyperphosphatemia in 1 infant, iron relative deficiency in 2 children and an asymptomatic increase in blood pressure in 1 hypertensive child. None of the 5 normotensive patients developed hypertension. We concluded that once weekly 150U/kg SC rHuEpo is effective in correcting anemia in children on CAPD. This regimen results in few side effects, decreases the cost of treatment and produces less distress to the patients by avoiding repetitive injections.

Three patients of a French family demonstrated an association of multiple endocrine neoplasia type 2A (MEN 2A) with a pruritic scapular skin lesion. The lesions are similar to those described as familial cutaneous lichen amyloidosis in unrelated MEN 2A and medullary thyroid carcinoma families, but histological, immunohistochemical, and ultrastructural analysis of skin biopsies from each patient in the French family did not show amyloid deposition. The topography of the lesion follows dermatomes C8-D3. The patients report not only pruritus but also paresthesia and hyperalgesia, and one showed touch hypoesthesia and pain hyperesthesia in the area of the lesion. Such an association of cutaneous and neurological features suggests notalgia paresthetica (NP), a neuropathy of the posterior dorsal rami nerves. We thus suggest that the cutaneous lesions associated with MEN 2A might be secondary to pathology in the neural crest-derived dorsal sensory nerves. The amyloid, when present, would be secondary to scratching. We propose that patients presenting with familial NP be suspect for MEN 2A.

We studied the effect of tranilast on the growth of carrageenin-induced granulation and the increase in capillary permeability induced by inflammatory agents in rats. In the carrageenin-induced granulation model, tranilast (50 or 100-200 mg/kg, p.o.) decreased significantly and dose-dependently the weight and the hydroxyproline content of the granulation tissue. Tranilast, however, showed no effect on the healing day of locally wounded dorsal skin of rats. Triamcinolone (10 mg/kg, p.o.) also showed an inhibitory effect on the carrageenin-induced granulation model. Tranilast (50-400 mg/kg, p.o.) dose-dependently inhibited the enhancement of capillary permeability induced by the Ca ionophore A23187, bradykinin and xanthine oxidase. Moreover, tranilast (30 and 300 microM) suppressed superoxide production induced by FMLP in human neutrophils, but did not act as a superoxide scavenger. Considering that hypertrophic scar and keloid are conditions characterized by abnormal cell proliferation and excessive collagen accumulation accompanied with itch and pain, these results suggest that tranilast is useful as a therapeutic drug for hypertrophic scars and keloids.

Epidural administration of an opioid analgesic by means of a patient-controlled analgesia (PCA) system was compared with conventional intravenous PCA for pain relief after cesarean delivery. One hundred seventeen healthy women were randomly assigned to receive hydromorphone either intravenously (IV-PCA) or epidurally (EPI-PCA) after cesarean delivery with epidural bupivacaine for operative anesthesia. The hydromorphone requirements were 3.4 and 4.2 times more in the IV-PCA group on the first (P less than 0.01) and second (P less than 0.01) postoperative days, respectively. The mean number (+/- SD) of PCA demands during the first 24 h after the operation was 105 (+/- 88) for the IV-PCA group and 33 (+/- 48) for the EPI-PCA group (P less than 0.01). This difference was also significant 24-48 h after surgery. Although the EPI-PCA group utilized significantly less opioid medication, pain and sedation scores were similar in the two treatment groups; however, a significantly larger percentage of patients in the IV-PCA group (46% vs 22%) stated that they felt drowsy during the first postoperative day. Pruritus was reported more frequently in the EPI-PCA (67%) than in the IV-PCA (33%) group. Nausea was experienced by only 10% of patients in the IV-PCA and 6% in the EPI-PCA group. There was no evidence of postoperative respiratory depression, with minimal oxygen saturation values of 93% (+/- 3%) and 94% (+/- 1%) in the IV-PCA and EPI-PCA groups, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

We have studied postoperative analgesia and unwanted side effects of a single dose of a mixture of morphine and sufentanil administered extradurally with the effects produced by extradural injection of each opioid alone in 64 patients after Caesarean delivery. The patients were allocated randomly to receive morphine 4 mg (n = 21), sufentanil 50 micrograms (n = 22) or morphine 2 mg with sufentanil 25 micrograms (n = 21) via an extradural catheter in a double-blind design. Intensity of pain was measured using a linear visual analogue scale. Compared with the effect produced by morphine alone, the morphine-sufentanil combination produced more rapid onset of pain relief (19 (SD 5) min vs 79 (23) min for a 75% reduction of pain; P less than 0.01), whereas the duration and quality of analgesia assessed during 12 h was similar for these two groups. In contrast, patients receiving sufentanil alone required significantly more supplementary analgesia 4 h after administration than with morphine alone or morphine combined with sufentanil. There were no significant changes in cardiorespiratory variables in any group. Side effects consisted mainly of pruritus and nausea and did not differ between groups, with the exception of early and transient dizziness which was observed only in patients given sufentanil either alone or in combination with morphine. We conclude that a single extradural injection of morphine and sufentanil combines the short onset time produced by sufentanil and the long duration of analgesia attributable to morphine, thus providing excellent and prolonged analgesia after Caesarean delivery.

Forty-three patients recruited from general practice with symptom-producing chronic venous insufficiency in the lower limbs participated in a randomized double-blind clinical trial with Venoruton (300 mg x 3) or a placebo for 28 days. Twenty-eight patients were treated with Venoruton and 19 with a placebo. None of the patients received other forms of treatment for chronic venous insufficiency. No differences were observed between the two groups as regards changes in symptoms (swelling, pain, heaviness, restlessness, itching and cramps) the subjective assessment of the discomfort in the extremities or the circumference of the limbs. Venoruton does not appear to have any effect on chronic venous insufficiency in the lower limbs.
