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)

The aim of this study was to approach on a psychical point of view 27 patients suffering from chronic idiopathic urticaria (14), pruritus sine materia (6), alopecia areata (3), pathomimia (4), in order to examine the possibility that psychic disorders could act as triggering or aggravating the dermatological affection. Psychical assessment was evaluated by colloquy and by the administration of some psychodiagnostic tests: EPI, MMPI, Zung. The role of psychogenic factors in skin diseases is emphasized and the results obtained from the use of antidepressant and minor tranquilizer drugs are discussed.

The immunogenicity and safety of a purified Vero-cell rabies vaccine (PVRV, VERORAB; Aventis Pasteur, France) were evaluated in 171 patients treated for severe exposure to rabies (WHO category III contacts) at the Shandong Provincial Antiepidemic Station in Jinan and an EPI center in Ping Yin, China. Post-exposure treatment consisted of a single dose of equine rabies immunoglobulin (ERIG, 40 IU/kg body weight) on Day (D) 0, and intra-muscular administration of PVRV on D 0, 3, 7, 14 and 28. Antirabies antibody levels were evaluated on D 0, 7, 14, 28, 90 and 180 using the rapid fluorescent focus inhibition test. By D 14 all subjects had seroconverted (> or = 0.5 IU/ml), with a geometric mean titer of 50.3 IU/ml. Antibody titers remained above the seroprotection threshold in all patients for 3 months, and in 98.2% of subjects for 6 months. All patients were still alive 6 months after the start of treatment. PVRV and ERIG were shown to be well tolerated and no serious adverse events were observed. Following PVRV administration, 12 patients (7.0%) had at least one local reaction (mostly pruritus, erythematous rash and pain). Fourteen patients (8.2%) developed local reactions at the site of ERIG administration. Twelve patients (7.0%) developed systemic reactions following post-exposure treatment, the most frequent of which were pruritus, rash and vertigo. This study demonstrates that PVRV is immunogenic and safe in Chinese patients treated according to WHO recommendations for severe rabies exposure.

The experimental models and the studies in man employed to assess the skin and general safety of a newly developed glyceryl trinitrate (GTN, CAS 55-63-0) transdermal patch, hereinafter coded EPI, are described. EPI was found well tolerated by the skin after single or 28-day repeated epicutaneous application on the rabbit, devoid of phototoxicity in the mouse, devoid of skin sensitizing potential in the guinea pig and devoid of photosensitizing effects in the guinea pig. Tested were also, with negative results, the cytotoxic, hemolytic and genotoxic potential, the presence of bacterial endotoxins, the systemic and intracutaneous toxicity, and the possible conjunctival irritant effects. The application of EPI for 14 consecutive days on the thoracic skin of 28 healthy volunteers did not provoke subjective discomfort such as itching, burning or pain, or objective skin lesions. On the application site a light and transient erythema was often found demonstrating the transcutaneous absorption of the vasodilating GTN from the patch. The 14-day application was followed after two weeks by the application of a challenge EPI patch to detect a possible skin sensitization by EPI. No skin reaction was elicited, showing that also in man EPI is devoid of skin sensitizing potential. During the 14-day application of EPI several GTN commonly induced systemic adverse reactions were observed, particularly headache, confirming the systemic bioavailability of GTN from the patch. Headache rapidly disappeared after removal of the patch, in parallel with the decrease of the blood concentrations of GTN and of its active metabolites, consistently with the previous pharmacokinetic findings. This is an advantage of the administration of GTN with the transdermal patch because, in the case of unbearable headache, the patient is relieved by the simple removal of the patch.

Insect bite hypersensitivity (IBH) is a Th-2, IgE-mediated dermatitis of horses caused by bites of insects of the genus Culicoides that has common features with human atopic dermatitis. Together with Th-2 cells, the epithelial barrier plays an important role in development of type I hypersensitivities. In order to elucidate the role of the epithelial barrier and of the skin immune response in IBH we studied the transcriptome of lesional whole skin of IBH-horses (IBH-LE; n = 9) in comparison to non-lesional skin (IBH-NL; n = 8) as well as to skin of healthy control horses (H; n = 9). To study the "baseline state" of the epithelial barrier, we investigated the transcriptome of non-lesional epidermis in IBH-horses (EPI-IBH-NL; n = 10) in comparison with healthy epidermis from controls (EPI-H; n = 9). IBH-LE skin displayed substantial transcriptomic difference compared to H. IBH-LE was characterized by a downregulation of genes involved in tight junction formation, alterations in keratins and substantial immune signature of both Th-1 and Th-2 types with particular upregulation of IL13, as well as involvement of the hypoxic pathway. IBH-NL shared a number of differentially expressed genes (DEGs) with IBH-LE, but was overall more similar to H skin. In the epidermis, genes involved in metabolism of epidermal lipids, pruritus development, as well as IL25, were significantly differentially expressed between EPI-IBH-NL and EPI-H. Taken together, our data suggests an impairment of the epithelial barrier in IBH-affected horses that may act as a predisposing factor for IBH development. Moreover, these new mechanisms could potentially be used as future therapeutic targets. Importantly, many transcriptional features of equine IBH skin are shared with human atopic dermatitis, confirming equine IBH as a natural model of skin allergy.
