Clinical trials

The goal of this clinical study is to find out whether using ketoconazole 2% shampoo for seven days works better than using it for three days in treating pityriasis versicolor. The study will also evaluate the safety of both treatment durations. The main questions this study aims to answer are: * Does treatment with ketoconazole 2% shampoo for seven days result in better mycological efficacy compared with three days of treatment in patients with pityriasis versicolor? * Does treatment with ketoconazole 2% shampoo for seven days lead to better clinical improvement compared with three days of treatment? * Are there differences in side effects between the seven-day and three-day ketoconazole 2% shampoo treatment regimens? * Are there differences in dermoscopic features of pityriasis versicolor before and after treatment with ketoconazole 2% shampoo when used for seven days compared with three days?

This clinical trial aims to evaluate whether direct neurotization using fully autologous components during autologous breast reconstruction improves postoperative breast sensation and sensory-related quality of life in women undergoing unilateral mastectomy. Direct neurotization involves coapting the recipient intercostal nerve to an autologous nerve graft placed within the flap to facilitate reinnervation. The study's primary questions are: 1. Does direct neurotization using fully autologous nerve grafts improve cutaneous sensory recovery, as assessed by Semmes-Weinstein monofilament thresholds measured at standardized breast locations? 2. Does neurotization enhance patient-reported sensory outcomes and quality of life, as assessed by the BREAST-Q Sensation Module? As secondary objectives, the study will assess whether biological predictors of nerve regeneration correlate with sensory outcomes. These include: 1. Neuregulin-1 (NRG1) expression in flap tissue biopsy; 2. Cross-sectional area of the recipient nerve fibres; 3. Breast morphometry measured at baseline and follow-up; 4. Intraepidermal nerve fibre density (IENFD) on skin biopsy. Participants will be randomly assigned to receive either: 1. Neurotized autologous breast reconstruction using fully autologous graft components, or 2. Standard (non-neurotized) autologous breast reconstruction. The study will compare these groups to determine whether neurotization accelerates or enhances the return of breast sensation over a 6-month follow-up period, with evaluations at 1 month, 3 months, and 6 months after surgery. Participants will undergo: 1. Autologous breast reconstruction with or without direct neurotization as part of their planned cancer surgery. 2. Sensory testing using Semmes-Weinstein monofilaments at baseline, 1, 3, and 6 months. 3. Completion of BREAST-Q questionnaires evaluating breast sensation, symptoms, and quality of life at each follow-up visit. 3\. Intraoperative tissue sampling for NRG1 analysis and nerve morphometry. 4. Skin biopsy (if applicable) to assess intraepidermal nerve fibre density. 5. Breast morphometry assessment using a breast morphometry measurement software tool. This study seeks to provide high-quality evidence on the effectiveness of direct neurotization using fully autologous components in restoring breast sensation and to explore biological predictors that may influence sensory recovery after autologous breast reconstruction.

The goal of this clinical trial is to learn if N-Acetylcysteine drug works to protect kidney function in adults patient with cancer. Kidney function will be measured by laboratory parameter using urine sample (KIM-1 urine) and blood sample (serum creatinine). The main questions it aims to answer are: 1. Does N-Acetylcysteine lower the level of KIM-1 (Kidney Injury Molecule) in patients urine indicating kidney function protection? 2. Does N-Acetylcysteine lower the level of creatinine in patients blood indicating kidney function protection? Participants will: 1. Had their blood and urine sample taken before taking the drugs (N-Acetylcysteine or placebo) 2. Underwent cisplatin based chemotherapy 3. Taken placebo or N-Acetylcysteine for seven days (1 day before chemotherapy, on the chemotherapy day, and 5 days after chemotherapy) 4. Had their blood and urine sample taken twice after taking the drugs (1 week and 3 weeks after chemotherapy) 5. Had their symptoms monitor during and after taking the drugs. Every possible side effect, hospitalization, or death will be recorded.

The goal of this clinical trial is to learn if Cognitive Behavioral Therapy (CBT) can improve psychological, neurological, and hormonal aspects in women undergoing In Vitro Fertilization (IVF). The main questions it aims to answer are: * Is CBT effective in improving psychological aspects (anxiety, depression, and coping mechanism) in women undergoing IVF? * Is CBT effective in improving neuroendocrine aspects (cortisol levels, neuroepinephrine levels, free trioodothyronine levels) in women underoing IVF? Researchers will compare CBT to no intervention to see if CBT is effective in improving psychoneuroendocrine aspects.
