Active clinical trials for "Pruritus"

Hydroxyzine is one of antihistamines that antagonizes H1 receptor, and it's effects are reducing pruritus, nausea/vomiting, and the mild effect of sedation.With these effects Hydroxyzine should be used in the prevention of these symptoms.

Can epidural nalbuphine reduce incidence or severity of epidural morphine induced pruritus in patient undergoing cesarean section?

This study will look at melatonin vs. first generation antihistamine vs. placebo in improving nighttime itching in children with atopic dermatitis.

Dexamethasone is commonly used in clinical practice.However, intravenous dexamethasone sodium phosphate may cause perineal discomfort.With the popularization of comfortable medical technology, patients have higher and higher requirements for comfortable medical treatment.Perineal pruritus caused by intravenous dexamethasone sodium phosphate may cause adverse physiological and psychological effects on patients and increase the incidence of unpleasant experiences during anesthesia.Therefore, it is very important to find a practical and effective method of inhibition.Midazolam is a water-soluble benzodiazepine commonly used in clinical practice, which has been proved to effectively inhibit the itching caused , while its effect on the itching caused by dexamethasone has not been reported.By observing the effect of pre-injection midazolam on the perineal itching caused by dexamethasone sodium phosphate, this experiment intends to preliminarily explore its possible mechanism .

Purpose: To study the etiology and the epigenetic pathways leading to and regulating chronic itch. Similarly, to examine the mechanisms underlying skin changes, including epigenetic alterations while also testing the efficacy of opioid antagonists in atopic dermatitis. In this study, the investigators aim to examine chronic sensory disorder mechanisms related to chronic itch.

Pruritus is a troublesome side-effect of neuraxial (epidural and intrathecal) opioids. Sometimes it may be more unpleasant than pain itself. The incidence of pruritus is 83% in postpartum patients and 69% in non-pregnant patients including males and females (1). Some researchers concluded that slow injection rate of hyperbaric bupivacaine may be a simple and effective way to reduce the incidence and severity of hypotension during cesarean section under spinal anesthesia (2). In this new research I want to investigate the effect of slow injection of fentanyl separately, in spinal anesthesia for cesarean section, on the incidence of itching In this double blind randomized study two hundred parturient will be randomly allocated in to two groups; Group (R) will receive 25 mic fentanyl spinal ( after dilution with 2.5 ml CSF) in 15 seconds. Group (S) will receive the same dose in 90 seconds All parturient will receive 10 mg bupivacaine in 45 min after fentanyl. Exclusion criteria will be those with allergy to any medications, contraindications to spinal anesthesia, those who requested sedation, presence of skin lesions that may cause itching and opioid addiction. Parturient will be monitored regarding the incidence of itching, hypotension, nausea and vomiting. Onset and level of sensory block will also be recorded.

The purpose of this study is to define the mechanisms that underlie the refractory pruritus (itch) in Cutaneous T-Cell Lymphoma (CTCL).

Very little is currently known about the pathophysiology of pruritus sine materia according to the etiology. The creation of this cohort should make it possible to improve our clinical and biological knowledge according to the etiology, by collecting blood, skin, feces, and clinical data.

The main objective of this study is to identify by functional and structural MRI which are the brain areas activated in various pruritic situations to deduct a model describing the different causes of pruritus. The investigators are going to compare two chronic pruritus conditions (histaminergic urticaria and non histaminergic: psoriasis) to a healthy control group. The secondary objective of this study is to specify a classification index from the physiological results obtained by brain imaging to differentiate multiple types of pruritus.

The aim of this study is to determine the effect of aromatherapy massage on itching, comfort, skin pH level and skin moisture in individuals with liver disease. Research Hypotheses: H1: Aromatherapy massage has an effect on the level of itching in individuals with itchy liver disease. H2: Aromatherapy massage has an effect on the general comfort level in individuals with itchy liver disease, H3: Aromatherapy massage has an effect on skin pH level in individuals with itchy liver disease. H4: Aromatherapy massage has an effect on skin moisture in individuals with itchy liver disease.
