Background Melasma is a common hyperpigmentation disorder with numerous, but often unsatisfactory treatment options. Aims A pilot study to evaluate the efficacy and safety of a novel topical combination of 12% hydroquinone, 6% kojic acid, and 5% vitamin C cream for melasma. Patients and methods A pilot study of 6 women with melasma was conducted at an academic dermatology department and a private dermatology practice to evaluate the efficacy of a topical combination of 12% hydroquinone, 6% kojic acid, and 5% vitamin C cream, entitled the "Tam Formula." Two blinded evaluators calculated Melasma Area and Severity Index (MASI) Scores before and after treatment to evaluate change from baseline, and statistical analysis was performed. Results Treatment with this combination topical cream resulted in an average 63.77 ± 22.10 percent reduction in MASI Scores. Conclusions While there is a need for further investigation, this pilot study indicates the Tam Formula may provide an alternative treatment option for melasma.

BACKGROUND: Postoperative concerns after Mohs micrographic surgery (MMS) are not well characterized. OBJECTIVE: To better define patient concerns and contributing characteristics in the immediate postoperative period after MMS. MATERIALS AND METHODS: A standardized telephone encounter template was implemented to better assess patient concerns in the 24-hour postoperative period. A review was then performed of patients undergoing MMS from October 2016 to July 2017 to assess for the most common patient concerns and association with clinical characteristics. RESULTS: We included 307 patients. Overall, 60.6% of patients reported a concern. Fifty-four percent of patients reported pain. Most pain was characterized as “a little” (67.7%). On univariate analysis, flap repairs, location on the upper extremities, and swelling were associated with higher mean postoperative pain. Tumor type was not associated with increased pain. On multivariate analyses, patients with larger defects and associated edema were statistically significantly associated with higher degrees of pain. CONCLUSION: Over half of patients experience postoperative concerns after MMS, most commonly pain. The immediate postoperative period may be an optimal time to identify patient concerns allowing for reassurance or early intervention when necessary.

Melasma on the face is difficult to treat and is often refractory to multiple treatment modalities.To investigate the safety and efficacy of fractional photothermolysis (FP) for the treatment of melasma and to determine recurrence rates with this treatment method.Eight female patients (Fitzpatrick skin type II-IV) with clinically diagnosed melasma on the face were treated using FP (1,550 nm Fraxel SR laser). Two to seven treatments were performed at 3- to 8-week intervals. Treatment levels ranged from 3 to 10, corresponding to 9% to 29% surface area coverage (8-10 passes per treatment). Energies used ranged from 6 to 40 mJ. Physician and patient assessments were recorded at each visit and at a follow-up visit 7 to 36 months (mean 13.5 months) after the last treatment session.At the last treatment, assessments revealed greater than 50% clinical improvement in melasma in five of eight patients. Follow-up assessments by the evaluating physician revealed sustained efficacy in five patients. Recurrence was reported in three patients. No significant adverse effects were noted.FP is a safe and effective treatment for refractory melasma, with long-term remission.

Background Refractory dermatitis can frequently cause loss of personnel and poses an economic drain on the military due to the evacuation of civilians and soldiers out of theater. Objective Proof-of-concept retrospective analysis to review the utility of the T.R.U.E. Test in the combat environment. Methods Thirty T.R.U.E. Tests were performed by the dermatology clinic in Baghdad, Iraq, between January 15, 2008, and July 15, 2008. Thirty active-duty and civilian contractors referred to the dermatology clinic for dermatitis were tested and four others were clinically rechallenged for suspected bacitracin contact allergy. Results Of the 30 patients tested, 14 (46.7%) had a positive test reaction to at least one antigen. In these positive tests, nickel, neomycin, and thimersol each comprised 17% followed by neomycin, thimerosal, budesonide, epoxy resin, potassium dichromate, p-phenylenediamine, formaldehyde, quaternium-15, fragrance, and balsam of Peru. All four clinical rechallenges for bacitracin allergy were also positive. Conclusions The use of the T.R.U.E. Test in the combat desert environment is an efficient, easy, and clinically relevant method of testing for allergic contact dermatitis. Continued study of the prevalence of allergic contact dermatitis at Ibn Sina Hospital, Baghdad, Iraq, is recommended.

Background Several specialties and textbooks continue to advocate that local anesthesia using epinephrine should not be used during surgery involving the digits. Objective We sought to assess the association between local anesthesia (buffered 0.5% lidocaine and 1:200,000 epinephrine) injected into digits, comorbid patient conditions, and postoperative complications including ischemia or necrosis. Methods A retrospective review of all patients presenting for Mohs micrographic surgery in a private practice ambulatory surgery center was performed between October 2002 and January 2009. Patient factors including amount of anesthesia injected; preoperative vitals; history of hypertension, stroke, or circulatory disorders; and presence of anticoagulation were assessed. Results Three Mohs surgeons' patients were included in the study. No digital blocks were performed; local anesthesia was infiltrated directly into the tumor site. Patients received buffered 0.5% lidocaine plus epinephrine 1:200,000. Of 63 patients presenting for surgery (59 fingers and 4 toes), there were no cases of digital ischemia or necrosis. Approximately one-third had a circulatory disorder or diabetes, and more than half had a diagnosis of hypertension or were taking anticoagulation. The average amount of anesthesia injected was 6.92 mL, with the greatest amount being 25 mL. Limitations This was a retrospective review with possible overestimation of adverse effects as a result of referral bias of complicated patients to an ambulatory surgery center for treatment. Conclusion There is no evidence that buffered 0.5% lidocaine with epinephrine 1:200,000 causes ischemia or necrosis when injected into digits. This is true despite a history of circulatory disorders, thrombosis, diabetes, smoking, anticoagulation, or significant preoperative hypertension.

Actinic keratosis (AK), also termed solar keratosis and senile keratosis, is a very common lesion of the skin and is a potential precursor to squamous cell carcinoma (SCC). Estimates of AK progression to invasive SCC range from less than 1 to16% [1]. SCC of the skin has the potential to metastasize and may account for up to 20% of deaths from skin cancer [2]. With the incidence of nonmelanoma skin cancer on the rise, treatment for AKs has been recommended to reduce the development of invasive SCC, to lower healthcare expenditure, and for patient well-being [3, 4]. The likelihood of an invasive SCC evolving from one AK lesion has been estimated to occur at a rate of 0.075–0.096% per lesion per year. For a person with the average number of AKs, or 7.7 AKs, SCC would develop at a rate of 10.2% over 10 years. Other estimates quote even higher rates for untreated lesions, from 13 to 20% over a 10-year period [4].

Reconstruction of the scalp after Mohs surgery can pose dilemmas for the dermatologic surgeon, especially for extensive tumors. The authors present a unique technique for removing large in-situ epidermal tumors of the scalp during Mohs surgery in four patients. Although invasive tumor was removed with a standard No. 15 scalpel, the extensive epidermal component of the tumor was removed through the mid-dermis using the flexible scalpel. This technique allowed the superficial defect to heal by second intention. The results showed minimal scarring and hair regrowth in what could have been large defects requiring complex reconstruction.

A 43-year-old African-American female with anemia secondary to uterine leiomyomas and menorrhagia presented with induration and stiffness of the right arm and hand four weeks after receiving intravenous iron infusions at multiple infusion sites along the right proximal forearm. Multiple intravenous sites between her right antecubital fossa and wrist had to be used because developing pain necessitated the site changes. The iron infusions were performed because the patient had refused blood transfusions and her symptoms failed to resolve on oral iron supplementation. The skin induration persisted and progressed for several months at which time a skin biopsy was performed. The skin histology was consistent with eosinophilic fasciitis and her complete blood count was notable for a peripheral eosinophilia. Because of the location of the fibrosis and the time proximity in relation to her infusions, a relationship between the iron infusions and eosinophilic fasciitis was made. Cutaneous fibrosis has been linked to immunologic dysfunction, autoantibody production, tissue hypoxia, and vascular damage, which may have been contributing factors in this patient. Eosinophilic fasciitis has been linked to certain drugs and chemicals, notably L-tryptophan ingestion and the statin family of drugs.

Since July 2004, the United States (U.S.) Army has operated a forward-deployed dermatology clinic in Baghdad, Iraq. This paper outlines the prevalence of skin disease among deployed service men and women in Operation Iraqi Freedom.A cross-sectional study was performed for all dermatology visits presenting to the Combat Dermatology Clinic, Ibn Sina, Iraq, between January 15, 2008 and July 15, 2008.In the six-month period reviewed, 2,696 total patients were evaluated. The most prevalent diagnoses included eczematous dermatitis [17%, n=462] and benign neoplasms [14%, n=375]. Eight percent (n=205) of the total visits were for skin cancer. This included: basal cell carcinoma, squamous cell carcinoma both in-situ and invasive, mycosis fungoides and melanoma. Actinic keratosis comprised 5% of the total visits (n=129). Bacterial infections comprised 6% (n=158) of the total visits and 31 of these cases were community acquired methicillin resistant Staphylococcus aureus (MRSA).Cross-sectional study with referral bias.This is the largest publication of the prevalence of skin disease in an exclusively dermatologic clinic in a combat setting. For the first time the presence of skin cancer is noted in a combat setting. The prevalence of MRSA is noted and was exclusively seen in U.S. soldiers. There was a statistically significant rise in the prevalence of eczematous dermatitides when compared with previous conflicts. Dermatologists can have a significant and strategic impact on deployed military medicine.

BACKGROUND Despite the large contribution by dermatology to military readiness, there have been no published reports regarding dermatologic surgery or skin cancer in the combat environment. OBJECTIVE To outline the contribution of dermatologic surgery, including skin cancer and benign tumors, to deployed service men and women in Operation Iraqi Freedom. METHODS A retrospective chart review was performed of all dermatology visits at the 86th Combat Support Hospital, Ibn Sina, Iraq, between January 15, 2008 and July 15, 2008. RESULTS Two thousand six hundred ninety-six patients were seen in the combat dermatology clinic during the 6-month period reviewed; 8% (205/2,696) of the total visits were for skin cancer, and another 129 patients were treated for actinic keratosis. The specific diagnoses were basal cell carcinoma (n=70), in situ and invasive squamous cell carcinoma (n=68), mycosis fungoides (n=1), bowenoid papulosis (n=1), and in situ and invasive melanoma (n=9). Benign lesions and tumors accounted for 14% (357/2,696) of total patient visits. Three hundred seven surgeries were performed during the 6-month period (178 skin cancers and 129 benign lesions), and 20 patients were referred for Mohs micrographic surgery. The surgical complications included five postoperative wound infections (1 methicillin-resistant Staphylococcus aureus), one wound dehiscence, and seven allergic contact dermatitis. CONCLUSIONS To the authors' knowledge, this is the first publication regarding skin cancer and dermatologic surgery in the combat setting. This report outlines the important contribution of dermatologic surgery in the combat environment. The authors have indicated no significant interest with commercial supporters.

Pain characteristics and analgesia in patients undergoing Mohs micrographic surgery have not been systematically studied. It is important to know about pain after Mohs micrographic surgery to better serve patient needs.We sought to measure pain in patients after Mohs micrographic surgery, and to investigate the relationship among postoperative pain, surgical characteristics, patient characteristics, and analgesics used.The Wong-Baker 0-to-10 pain scale was prospectively administered postoperatively to all patients presenting for Mohs micrographic surgery in a private practice setting between October 1, 2007, and December 31, 2008. Patients recorded their pain level from the day of surgery through postoperative day 4. The age, sex, location of surgery, number of lesions operated on, postoperative size, type of repair, severity of pain, and oral analgesics consumed and dosages used were recorded.A total of 433 patients were included in the final analysis. The highest pain scores were found on the day of surgery and steadily declined until postoperative day 4 (P.000). In all, 52% of patients took pain medication on the day of surgery, which declined successively with each postoperative day. The highest mean pain scores were statistically significantly associated with repair type (flaps), age (66 years), number of lesions, and consumption of narcotics for pain relief. No statistically significant differences existed for sex or postoperative defect size.The instrument used to measure pain relied on patient self-report in a private practice surgery center. Only the validated Wong-Baker pain scale was used to assess pain in this study.Approximately half of the patients after Mohs micrographic surgery take medication for pain control. Type of closure, location of surgery, age, and type of pain medication taken were significantly associated with postoperative pain.

A 64-year-old man presented with a superficial, well-demarcated, skin-colored tumor on the left posterior scalp that measured 4 x 5 x 6 cm. The tumor was nearly hairless, rubbery, non-tender, and mobile over the underlying subcutaneous tissues. The lesion had grown slowly since arising approximately 30 years ago. Treatment options were declined in the past. However, with relatively more rapid growth over the past five years, the nodule began to cause intermittent pain and interfere with the patient's ability to lie on his back. The patient denied a history of similar lesions in himself or his family. A biopsy specimen showed a ruptured proliferating trichilemmal cyst with focal calcification. Complete excision is recommended for all benign proliferating variants owing to their potential for locally aggressive behavior and malignant transformation.

A 37-year-old woman presented with a one-year history of asymptomatic, red-brown patches and plaques on the abdomen and extremities, in the context of Raynaud phenomenon and anti-centromere antibodies. Two biopsy specimens confirmed the diagnosis of inflammatory morphea. Even in the absence of initial symptoms to support systemic disease, patients presenting with morphea in the setting of Raynaud phenomenon or anti-centromere antibodies deserve close surveillance for the possibility of CREST syndrome and systemic sclerosis.

A 75-year-old woman with end-stage renal disease on hemodialysis presented with a 2-month history of progressive skin thickening of the lower extremities. A punch biopsy specimen showed plump fibroblasts entrapping collagen bundles and positive staining for CD34 and procollagen. These changes were consistent with a diagnosis of nephrogenic fibrosing dermopathy (NFD). Nephrogenic fibrosing dermopathy is a rare, sclerosing disorder in patients with renal failure, which may be mistaken for scleromyxedema. The etiology of NFD is unclear but may be associated with systemic involvement, antecedent surgical procedures, gadolinium, or an underlying hypercoagulable state. The treatment is limited, and only a few reported cases have shown remission after stopping dialysis in transient renal failure.

A 51-year-old man presented with itchy, erythematous patches and plaques on his trunk, arms, and legs. A skin biopsy specimen showed mycosis fungoides. Initially the patient did not respond to PUVA photochemotherapy but later improved on NB-UVB phototherapy combined with bexarotene and interferon-alpha. The lesions progressed from erythematous patches and plaques to hyperpigmented patches with central depigmentation and localized areas of follicular repigmentation. The development of depigmentation after PUVA photochemotherapy for mycosis fungoides has been described in the literature and does not have associated prognostic implications. It is important to be cognizant of phototoxicity associated with PUVA photochemotherapy or NB-UVB phototherapy in patients with mycosis fungoides, who may be taking photosensitizing medications or have depigmented patches which renders them more sensitive to lower doses of ultraviolet light.

To estimate the value of skin biopsy in the evaluation of suspected acute cutaneous graft-vs-host disease (GVHD) after allogeneic stem cell transplantation.Decision analysis using parameters specified by expert opinion for skin biopsy characteristics, prevalence of acute GVHD, and value of potential outcomes. One-, 2-, and 3-way sensitivity analyses were performed.Major stem cell transplantation centers in the United States.Hypothetical cohort of patients with suspected acute cutaneous GVHD after stem cell transplantation.The following 3 interventions were compared: treat immediately for GVHD without performing a skin biopsy, perform a skin biopsy and treat immediately but stop treatment if skin biopsy specimen findings are inconsistent with GVHD, and perform a skin biopsy and await results of the skin biopsy specimen before treating.Number of patients appropriately and inappropriately treated with each intervention, consistency of physician-reported behavior, individualized decision analyses, and preferred intervention based on the aggregate estimates of respondents.The decision to treat immediately for GVHD without performing a skin biopsy yielded the best clinical outcome for the specified clinical setting and under the parameters specified by expert opinion. One-way sensitivity analyses showed that these conclusions are robust if the prevalence of acute cutaneous GVHD in stem cell recipients with rash is greater than 50%, if the sensitivity of skin biopsy specimen is less than 0.8, and the specificity of skin biopsy specimen is less than 0.9. Only 25% of physicians interviewed chose an intervention consistent with their estimates of prevalence, test characteristics, and outcome evaluations, indicating an opportunity to improve management of this important clinical condition.This decision analysis modeling technique predicts that in patient populations in which the prevalence of GVHD is 30% or greater (typical for allogeneic stem cell transplantation), the best outcomes were obtained with treatment for GVHD and no skin biopsy. In populations with prevalence of GVHD of 30% or less, obtaining a skin biopsy specimen to guide treatment was predicted to provide the best patient outcomes.
