Article Abstract
Tattoo removal is considered a challenging field in cosmetic dermatology. Picosecond Q-switched Nd-YAG lasers targeting unique chromophores effectively manage this condition without serious complications. To evaluate the efficacy and safety of Picosecond Q-switched Nd-YAG laser in the treatment of black tattoos in the skin of middle eastern mostly skin type IV. The study was carried out on 20 patients with skin type IV the most common in middle eastern area with professional black tattoos. They were treated by Picosecond Nd-YAG laser (2 sessions 8 weeks apart). The percentage of improvement ranged from 20.0 to 95.0 (with a mean of 61 ± 24.6). 8 patients (40%) showed excellent improvement, 4 patients (20%) showed marked improvement, 4 patients (20%) showed moderate improvement, and 4 patients (20%) showed mild improvement. No severe side effects were detected. Picosecond Nd-YAG laser was an effective and safe technique in the treatment of professional black tattoos; with only 2 sessions most patients reached excellent to moderate response with minimal side effects.
The role of sentinel lymph node biopsy (SLNB) in locally advanced breast cancer (LABC) post-neoadjuvant chemotherapy (NACT) is debatable. We conducted a novel pilot study in which pre-NACT tattooing of breast lumps in LABC patients resulted in black tattoos being deposited in the axillary node. We hypothesized that this black node was the sentinel node.

Recent studies have shown that polycyclic aromatic hydrocarbons (PAHs) can be found in commercial black tattoo inks raising suspicion of tattoo-related PAHs exposure to cancer risk. We present a case of a 27-year-old Hispanic nonsmoker male with bladder cancer (BC) following extensive tattoo sessions totaling over 100 hours. The patient was treated with transurethral resection of the bladder tumor (TURBT) and adjuvant intravesical Bacillus Calmette-Guerin (BCG) therapy.
- The study aimed to assess hair dye usage and self-reported skin reactions among the Dutch population, finding that 63.1% of participants used hair dye and 6.8% reported adverse reactions.
- The research highlighted a positive link between hair dye users and various factors such as female gender, middle age, positive patch test results, and professions like hairdressing.
- Findings indicated that adverse reactions were commonly mild and more likely in individuals with prior henna tattoo experiences, particularly in females, suggesting a need for increased awareness about hair dye safety.
