Transient Postinflammatory Hyperpigmentation Following Eyelid Surgery.

PURPOSE: Our aim was to describe a rare mild complication of eyelid surgery presenting as transient hyperpigmentation along the suture lines. METHODS: A retrospective case series of 6 patients experiencing transient hyperpigmentation following eyelid surgery. Each patient underwent either blepharoplasty alone or blepharoplasty with ptosis repair utilizing Müller muscle conjunctival resection. Data including surgery type, hyperpigmentation laterality and location, time to diagnosis, follow-up time, and outcome were assessed. RESULTS: All 6 patients with hyperpigmentation were females. All patients underwent blepharoplasty, including 1 upper eyelid blepharoplasty and 4 with both upper and lower eyelid blepharoplasty. One patient underwent bilateral upper blepharoplasty with concurrent posterior approach ptosis surgery repair of the left upper eyelid. Hyperpigmentation was bilateral in all 5 blepharoplasty cases and unilateral in the ptosis repair case. Hyperpigmentation included the medial portion of the operated upper eyelid in all cases. Time to diagnosis ranged from 1 to 4 weeks postoperatively, and follow-up time ranged from 3 to 5 months. Management was conservative in all cases. Five patients experienced complete resolution, and 1 patient experienced near-complete resolution on a 3-month follow-up. CONCLUSIONS: Transient hyperpigmentation is a rare posteyelid surgery complication, generally with an excellent outcome not requiring additional intervention.

Retrospective clinical evaluation of Q-switched Nd:YAG laser safety and efficacy in tattoo removal: A new perspective on the Kirby-Desai scale.

BACKGROUND: With nearly 50% of the population in the United States, Italy, and Sweden tattooed with at least one tattoo, the demand for its removal has risen by 32% since 2011. Traditional removal methods, such as Q-switched (QS) laser-based tattoo removal, can be lengthy, requiring up to 20 sessions. AIM: This study presents a retrospective clinical evaluation of seven short-pulsed QS, dual-wavelength Nd:YAG laser, as an efficient alternative, that can potentially reduce the number of sessions needed as calculated by a founded scale. METHODS: The QS modality delivers high-intensity pulses in four wavelengths, ideal for removing multicolored tattoos, of which two were used. We studied 11 patients who underwent 3-8 treatments (average 5.09) every 2-3 months. Each tattoo was assessed using the Kirby-Desai scale, considering the following factors: location, Fitzpatrick skin type, ink amount, layering, scarring, tissue changes, and tattoo color. Follow-ups were conducted after 6 months and at 4-5 years following last session. RESULTS: The long-term follow-up presented a significantly higher tattoo removal efficiency than the short-term follow-up (p < 0.001), indicating a sustained process of ink breakdown and elimination. Notably, the actual number of treatments were significantly lower than that predicted by the Kirby-Desai scale (average 5.09 vs. 9.9, p < 0.001). No severe adverse events were reported. CONCLUSIONS: In conclusion, the QS Nd:YAG laser offers a safe and effective alternative for tattoo removal, requiring fewer treatments than initially expected.

Is early appendectomy in adults diagnosed with acute appendicitis mandatory? A prospective study.

INTRODUCTION: Prompt appendectomy has long been the standard of care for acute appendicitis in order to prevent complications such as perforation, abscess formation, and diffuse purulent or fecal peritonitis, all resulting in increased morbidity and even mortality. Our study was designed to examine whether the time from the beginning of symptoms to operation correlates with the pathological degree of appendicitis, incidence of postoperative complications, or increased length of hospital stay. METHODS: A prospective study of 171 patients who underwent emergent appendectomy for acute appendicitis in the course of 2 years was conducted in a single tertiary medical center. The following parameters were monitored and correlated: demographics, time from the onset of symptoms until the arrival to the emergency department (patient interval (PI)), time from arrival to the emergency department (ED) until appendectomy (hospital interval (HI)), time from the onset of symptoms until appendectomy (total interval (TI)), physical examination, preoperative physical findings, laboratory data, pathologic findings, complications, and length of hospital stay. RESULTS: The degree of pathology and complications were analyzed according to the time intervals. The time elapsed from the onset of symptoms to surgery was associated with higher pathology grade (p = 0.01). We found that longer time from the onset of symptoms to hospital arrival correlates with higher pathology grade (p = 0.04), while there was no correlation between the hospital interval and pathology grade (p = 0.68). A significant correlation was found between the pathology grade and the incidence of postoperative complications as well as with increased length of hospital stay (p = 0.000). CONCLUSION: Time elapsed from the symptom onset to appendectomy correlates with increased pathology grade and complication rate. This correlation was not related to the HI. Since the HI in our study was short, we recommend an early appendectomy in adults in order to shorten the TI and the resulting complications.

Anti-laminin-332 mucous membrane pemphigoid developing after a diphtheria tetanus vaccination.

IMPORTANCE: Bullous pemphigoid (BP) has been previously described to develop after vaccination in 26 patients. Immunoblotting or enzyme-linked immunosorbent assays (ELISAs), which were performed for 7 of these patients, have always shown circulating autoantibodies against BP180 and/or BP230 antigens. A case of anti-laminin-332 mucous membrane pemphigoid (MMP) that developed shortly after a diphtheria tetanus vaccination is described, with a review of the literature on postvaccination BP. OBSERVATIONS: A 29-year-old man developed an acute eruption of oral and cutaneous blisters and erosions 2 days after receiving a diphtheria tetanus vaccination. The histopathological, immunohistochemical, immunofluorescent, ELISA, and immunoblotting assay results were compatible with anti-laminin-332 MMP. The serum autoantibodies reacted with the α3 and ß3 subunits of laminin-332. The disease was controlled by administering a combination of glucocorticosteroids and dapsone. CONCLUSIONS AND RELEVANCE: The development of acute MMP shortly after a diphtheria tetanus vaccination may have been serendipitous, a result of a nonspecific bystander activation of the immune system, or due to structural mimicry between domains of the toxoid molecule and a subunit of laminin-332.
