Q-switched 532 nm Nd:YAG laser therapy for physiological lip hyperpigmentation: novel classification, efficacy, and safety.

BACKGROUND: Physiological lip hyperpigmentation (PLH) is a common cosmetic concern in the Middle East and Asia. It is characterized by homogeneous symmetric diffuse hyperpigmentation affecting both lips. There is no satisfactory treatment for this condition. The aim of this study is to evaluate the efficacy and safety of Q-switched (QS) 532 nm Nd:YAG laser for PLH. METHODS: A total of 30 patients with clinical diagnosis of PLH were retrospectively reviewed and included in the study. Patients underwent at least one laser treatment using QS 532 nm with a minimum follow up of six months. Laser parameters were as follows: spot size 2-3 mm, pulse duration 20 ns, fluence 2-4 J/cm2. One to three sessions were performed depending on clinical response. Two methods were used for assessment: patient satisfaction and independent physician assessment. PLH was classified as grade 1 (upper lip fully affected plus only border of lower lip), grade 2 (upper lip fully affected plus most of lower lip), and grade 3 (majority of both lips hyperpigmented). RESULTS: Excellent (>75% improvement) response was achieved in 30% of patients. Good (51-75% improvement) response was seen in 37% and 43% of patients according to patient satisfaction and independent physician assessment, respectively. Majority of patients required only one treatment session. Reactivation of herpes labialis occurred in two patients, and mottled hypopigmentation in three patients. None of the patients developed persistent hyperpigmentation or scarring. CONCLUSIONS: PLH can be effectively treated with QS 532 nm Nd:YAG laser and is well tolerated by patients.

Use of Complementary and Alternative Medicine Among Dermatology Outpatients: Results From a National Survey.

BACKGROUND: Little is known about the prevalence and practice of complementary and alternative medicine (CAM) among dermatology patients in the Arab world. The aim of this study was to determine knowledge and attitudes about CAM, prevalence of its use, reasons for its use, and types of CAM used in dermatology patients in Saudi Arabia. METHODS: This was a national survey of various regions of Saudi Arabia. In this cross-sectional study, dermatology outpatients were interviewed using a questionnaire. Sociodemographic characteristics, acceptability, utilization pattern, and reasons for CAM use were elicited. Dermatology life quality index (DLQI) was obtained. RESULTS: Overall, 1901 patients returned complete questionnaires out of 2500 distributed (76% response rate). Of these, 808 (40%) were CAM users, and the majority were woman (55.1%), with a mean age of 31.6±12 years. Most were literate (71.2%) and just over half were married (51.9%). Patients with acute skin diseases were found to be more likely to use CAM (P=.027). The mean DLQI score was higher (worse quality of life) among CAM users than among nonusers (P=.002). The results showed that 315 of 801 (40%) and 250 of 601 (30%) CAM users agreed that CAM methods are safer and more effective than modern medicine, respectively, and 83% will continue to use CAM in future. The most commonly used CAM modalities were vitamins, prayers, natural products, and herbs. Responses indicated that 379 of 803 (47.2%) CAM users did not consult their doctor before using CAM, and 219 of 743 (30%) did not obtain sufficient answers regarding CAM use from their dermatologists. CONCLUSIONS: There is a significant use of CAM among dermatology outpatients in Saudi Arabia. In view of the common belief that CAM has fewer side effects than conventional medicine, dermatologists need to increase their awareness of CAM.

Use of Vitamins and Minerals in the Treatment of Hair Loss: A Cross-Sectional Survey among Dermatologists in Saudi Arabia.

BACKGROUND: Several controversies exist regarding the use of vitamin and mineral supplements in treating hair loss. OBJECTIVES: To explore practices, knowledge, and attitudes for using vitamins and minerals in treating hair loss among dermatologists in Saudi Arabia. METHODS: A self-administrated questionnaire containing 33 questions was distributed to 177 dermatologists attending a national dermatology conference in Riyadh, Saudi Arabia, in 2012. RESULTS: Of the 177 attending dermatologists, 144 responded to the questionnaire (81% response rate). Vitamins and minerals were recommended for treating at least one type of hair loss by 60%. Vitamins and minerals were most commonly used for acute telogen effluvium (62%). The majority (72%) reported a good knowledge of vitamins and minerals toxicity. CONCLUSION: Although dermatologists in Saudi Arabia displayed positive believes in the usefulness of vitamins and minerals in treating hair loss, further research is needed to prove their role in the management of different hair loss disorders.

Evaluation and diagnosis of the hair loss patient: part I. History and clinical examination.

Hair loss (alopecia) is a common problem and is often a major source of distress for patients. The differential diagnosis of alopecia includes both scarring and nonscarring alopecias. In addition, many hair shaft disorders can produce hair shaft fragility, resulting in different patterns of alopecia. Therefore, an organized and systematic approach is needed to accurately address patients' complaints to achieve the correct diagnosis. Part 1 of this 2-part continuing medical education article on alopecia describes history taking and the clinical examination of different hair loss disorders. It also provides an algorithmic diagnostic approach based on the most recent knowledge about different types of alopecia.

Evaluation and diagnosis of the hair loss patient: part II. Trichoscopic and laboratory evaluations.

The use of trichoscopy for evaluating a number of hair and scalp disorders is gaining popularity. It is a simple and noninvasive in vivo tool for visualizing hair shafts and the scalp. Recently, alopecias have been classified according to their trichoscopic findings. The second part of this 2-part continuing medical education article reviews recent advances in this field and describes a systematic approach for using the differential diagnostic findings of trichoscopy in alopecia.

Frontal fibrosing alopecia: a retrospective clinical review of 62 patients with treatment outcome and long-term follow-up.

BACKGROUND: Frontal fibrosing alopecia is a distinctive form of scarring alopecia presenting with frontal and temporoparietal recession of the hairline. Its etiology remains unknown, and there are no universal treatment guidelines. We conducted a retrospective cohort study to define the clinical findings and treatment outcomes of 62 patients with frontal fibrosing alopecia, one of the largest cohorts to date. METHODS: Data analysis from case notes was performed on 62 patients with a diagnosis of frontal fibrosing alopecia seen from January 2004 to March 2012. RESULTS: Except for one male, all patients in this cohort were females (80% post-menopausal) and mostly Caucasians (81%). Age at onset was between 18 and 81 years. While 35% reported no symptoms, the majority (65%) had itching, pain, or burning sensations. All patients had frontal hairline recession, and 81% had complete or partial loss of eyebrows. Perifollicular erythema and perifollicular hyperkeratosis occurred in 73% and 31%, respectively. Associated autoimmune connective tissue diseases were observed in 14% of patients. Reduction in symptoms and hairline stabilization were achieved in 97% of treated patients with intralesional corticosteroids. Thirty-one percent of patients were able to stop treatments and remained in remission for six months to six years. CONCLUSION: Frontal fibrosing alopecia is increasingly seen in postmenopausal women and rarely in men. Despite the limitations of a retrospective study, we conclude early intervention and treatment with intralesional triamcinolone acetonide may halt the progression of the disease; however, further controlled prospective studies are needed to establish treatment guidelines for frontal fibrosing alopecia.

Topical agents for hair growth promotion: what is out there?

Hair loss is a widespread complaint that carries a significant psychosocial burden for affected individuals. Androgenetic alopecia (AGA) is the predominant cause of hair loss seen in the dermatology clinic. Although a range of therapies are available, minoxidil remains the only approved topical treatment for AGA. Promising new topical agents are under current investigation.

Treatment of lymphangioma circumscriptum with sclerotherapy: an ignored effective remedy.

Lymphangioma circumscriptum is a rare lymphatic malformation that involves the skin and may extend to subcutaneous tissue and muscle. It usually presents as grouped micro- to macroscopic vesicles filled with lymph. Surgical excision has been the standard treatment, but it is associated with scarring, infection, injury to the surrounding structures, and a high recurrence rate. Herein, we report a 24-year-old male patient with a lymphangioma circumscriptum on the nape of the neck that was treated with two sessions of an intralesional injection of 1% sodium tetradecyl sulfate sclerotherapy with a very good result. After this treatment, there was no more discharge and a reduction in the lesion's size by 70%. Sclerotherapy using sodium tetradecyl sulfate can be considered a successful minimally invasive treatment option for lymphangioma circumscriptum.

A case of Pityriasis rosea concurrent with the novel influenza A (H1N1) infection.

Pityriasis rosea is a common skin disease with a self-limiting course. Multiple etiologies including viruses, bacteria, and fungi have been investigated in an attempt to confirm a casual association. Pityriasis rosea has not been associated with influenza virus, but has been associated with herpes simplex virus types 6 and 7. We encountered a case of a proven pandemic H1N1 infection associated with a clincopathological diagnosis of pityriasis rosea. We conclude that influenza A (H1N1) virus could either be a primary cause of pityriasis rosea or a trigger for reactivation of other viral causes.
