Filter by:This randomized prospective double-blind trial will be conducted on 80 Full-term pregnant females aged 21- 30 years presented for elective cesarean section under spinal anesthesia where they will be randomly allocated into two equal groups:- - Group F (40 Patients): Patients in this group will receive spinal anesthesia with 10 mg hyperbaric bupivacaine (2 ml) plus 25 ug of fentanyl (0.5 ml). - Group FN (40 patients): Patients in this group will receive spinal anesthesia with 10 mg hyperbaric bupivacaine (2 ml) plus 25 ug of fentanyl (0.5 ml) plus 20 ug naloxone. The study aim is to evaluate the effect of adding an ultra-low dose of naloxone (20 ug) to hyperbaric bupivacaine (10 mg0 and fentanyl (25 ug) in spinal anesthesia for C.S. Primary outcome: The incidence of pruritis Secondary outcome: The onset, the duration, the site, and the severity of pruritis.
This first in human, Phase 1/1b trial will evaluate the safety, tolerability, and pharmacokinetics of single and multiple ascending doses of EP547 in healthy subjects and subjects with cholestatic or uremic pruritus.
This is a double-blind, randomized, vehicle-controlled study to assess the efficacy, safety, and tolerability of 2 doses of B244 for the treatment of pruritus in adults with a history of atopic dermatitis. Subjects who meet the study entry criteria will be randomized in a 1:1:1 ratio to receive twice daily topical doses of B244 O.D. 5.0, B244 O.D. 20.0, or vehicle (placebo) for 4 weeks.
This is a multi-center, randomized, double-blind, placebo-controlled phase II clinical trial. The main objective is to evaluate the safety, pharmacokinetics, and efficacy of HSK21542 injection in subjects undergoing hemodialysis
Pediculosis capitis is a parasitic infestation that can cause scalp pruritus and quality of life disturbances. There are two objective measurement for pruritus, visual analog scale (VAS) and 5-D itch scale, which can assess the severity of the scalp pruritus and the latter can also asses the quality of life affected by pruritus. Even though VAS can not be used to evaluate the impact of pruritus on quality of life, it is very easy to use while 5-D itch scale is complex and not child-friendly. The aim of this study is to determine the relationship between two different pruritus scales and to establish validity of pruritus VAS scale in evaluating quality of life in children with pediculosis capitis. We compare two pruritus scale on students with pediculosis of two boarding school in Bogor, West Java, Indonesia.
In order to validate the accuracy and reliability of the histamine skin prick model for histaminergic itch and vasodilation, the dermal blood flow response induced by a histamine skin prick will be evaluated after the administration of certain H1-antihistamines. Besides, the influence of these H1-antihistamines on the dermal blood flow response induced by the topical application of cinnamaldehyde and capsaicin will be evaluated. Changes in dermal blood flow will be measured with laser speckle contrast imaging.
To determine the effective dose and the time course, the dermal blood flow response to histamine will be evaluated at different doses (5 µg, 15 µg and 50 µg). Histamine will be administered by a skin prick on the volar surface of subjects' forearm, alongside a negative control. Changes in dermal blood flow will be measured with laser Doppler imaging at different time points following the skin prick.
In order to validate the accuracy and reliability of the histamine skin prick model for histaminergic itch and vasodilation, the dermal blood flow response induced by a histamine skin prick will be evaluated after the administration of certain antipruritics. Besides, the influence of these antipruritics on the dermal blood flow response induced by the topical application of cinnamaldehyde and capsaicin will be evaluated. Changes in dermal blood flow will be measured with laser speckle contrast imaging.
To evaluate the inter-arm and inter-period reproducibility of the dermal blood flow response induced by a skin prick of histamine, subjects will receive histamine (10 mg/ml) and negative control skin pricks on the volar surface of both forearms during two subsequent study visits to allow an intra-individual comparison. Changes in dermal blood flow will be measured during the hour after the skin pricks with laser Doppler and/or laser speckle contrast imaging.
Immune checkpoint inhibitors (ICIs) are commonly used in the therapeutic arsenal of metastatic melanoma, Merkel cell carcinoma and cutaneous squamous cell carcinoma, thanks to their inhibiting effects on cytotoxic T-lymphocyte-associated protein 4 (anti-CTLA4) and anti-programmed death-1 (anti-PD1) respectively. These treatments can induce numerous cutaneous and non-cutaneous adverse effects that are mainly due to their immunological action. Their most frequent adverse effects are dysthyroidism, autoimmune hepatitis, colitis and skin disorders. Among those, pruritus is frequently reported as a side effect of these treatments. Its incidence has been estimated between 11% and 47%. Pruritus can deeply affect the patient's quality of life and may lead to treatment discontinuation. Until now, ICI-related pruritus has been poorly studied and it is not understood. In the literature, data on the presence and characteristics of pruritus in patients treated by ICIs were provided, without analyzing the causes of this pruritus. Indeed, it is not known if the occurrence of pruritus is related to direct or indirect effects of ICIs. Some authors reported a correlation between the occurrence of cutaneous adverse events under ICIs and the survival. The principal aim of our study was to analyze the putative causes of pruritus occurring in patients treated with ICIs for melanomas and cutaneous carcinomas. The other objectives were to assess the association between the occurrence of pruritus and survival, and between the other adverse events and pruritus.
