Cutaneous Warts

Cutaneous warts are one of the commonest presenting complaints of patients reporting to Dermatology OPD. Most of the warts are viral in origin and they can be either single or multiple. Their morphology varies from flat-topped, angulated, filiform etc. Nowadays, various options are available for management of warts which include topical application of medications, surgical excision and laser treatment. Conventionally, CO2 laser has been used for treatment of warts but Erbium: yttrium aluminium-garnet (YAG) laser is one of the lasers which has recently come into the literature for treatment of warts. This study highlights our experience of using of Erbium: YAG laser in the management of cutaneous warts.

Objective To examine the efficacy and safety of yttrium-aluminium garnet (YAG) laser vitreolysis for the treatment of vitreous floaters. Methods Consecutive adult patients with symptomatic vitreous floaters who attended Chongqing General Hospital from April to December 2016 were included in this prospective study. Patients had >3 mm between the vitreous opacity and retina/lens and acceptable quality peri-papillary Optical Coherence Tomography (OCT) images (i.e., signal strength ≥5). Those with history of glaucoma, severe cataracts, vitreous haemorrhages, retinal holes and/or macular disease were excluded from the study. Best corrected visual acuity (BCVA) and non-contact intraocular pressure (IOP) were measured before and for up to 6 months post-YAG laser vitreolysis. Anterior segment photography and peripapillary retinal nerve fibre layer (RNFL) measured by OCT were taken before and 6 months post-procedure. Questionnaires on patient satisfaction were completed 6 months post-procedure. Results No statistically significant differences in BCVA and IOP were observed before or after treatment. Anterior segment photography showed that vitreous opacities partially or completely disappeared after YAG laser treatment. The thickness of RNFL in four directions (upper, below, nasal and temporal) was not statistically significant different before or 6 months after the procedure. 75% patients reported significant improvement and 25% reported moderate improvement. Conclusion The results of this study conducted in a cohort of 30 Chinese patients showed that YAG laser vitreolysis was a well-tolerated and effective treatment for vitreous floaters. Randomised, controlled trials involving large numbers of participants monitored over an extended follow up period are required to confirm these results.

<p class="abstract"><strong>Background: </strong>Macular amyloidosis (MA) typically presents as small, dusky-brown or greyish pigmented macules, treatment of which remains challenging with topical and systemic therapies, however Q-switched neodymium-doped yttrium aluminium garnet (Nd:YAG) laser has proven to be an effective treatment modality to reduce hyperpigmentation.

Total number of pulses decreased with each treatment session as the intensity of the hyperpigmentation decreased. The procedure was repeated at one-month intervals for a total of 6 treatment sessions.</p><p class="abstract"><strong>Results: </strong>After completion of treatment sessions with Nd-YAG laser 36.66% patients showed &gt;50% improvement in the pigmentation. 66.6% patients were satisfied with the laser treatment. 33.3% patients showed &lt;25% improvement and unsatisfied with the treatment.</p><p class="abstract"><strong>Conclusion: </strong>MA remains an enigma and a source of concern for the suffering patients and physicians. Q-switched Nd-YAG laser 1064 nm has shown positive response in the reduction of pigmentation in MA.</p>

BACKGROUND: Dermal fillers are widely used for facial and body contouring. Polymethylmethacrylate (PMMA) is a permanent biphasic filler for soft tissue augmentation. In case of unwanted side effects, drug therapy and surgical excision have been commonly used with mixed results. AIM: We report on a series of patients with adverse events to PMMA and an innovative minor invasive procedure to reduce disfigurement by nodules and lumps. METHODS: We employed a subdermal, intralesional 1,064 nm neodymium-doped yttrium aluminium garnet (Nd: YAG) laser in combination with suction using a blunt liposuction cannula of 2.0-2.5 mm of diameter. RESULTS: For 12 years, a total of 81 consecutive subjects (79 females and 2 males) were treated. The average age of the patients was 43.7 years (range 26 to 76 years). Granulomas and lumps could be removed in a minor invasive procedure with tumescent anaesthesia. In a minority of cases, the procedure had to be repeated. The results were impressive and not adverse events related to intralesional laser therapy were observed, 86.4% of patients were satisfied. CONCLUSION: The procedure should be used before or in combination with classical surgery to remove PMMA in case of adverse tissue reactions to PMMA.

Adult hypopharyngeal haemangioma is an uncommon neoplasm. We present three cases of adult hypopharyngeal haemangioma which were successfully treated with a neodymium: yttrium–aluminium–garnet (Nd: YAG) laser in our hospital between 2000 and 2003. The patients in this series experienced no untoward events from the use of the laser. Excessive bleeding and airway problems were not encountered. Postoperative pain was minimal. Excellent long-term function and a full resolution of symptoms can be obtained using Nd: YAG laser. The laser provides a bloodless field and complete healing of the hypopharynx, without stenosis or scar formation.
