Acral erythema and systemic toxicity related to CHA induction therapy in acute myeloid leukemia.

Seventy-two adult patients with previously untreated acute myeloid leukemia received the CHA regimen as induction chemotherapy: CCNU 80 mg/m2 on day 1, Adriamycin 35 mg/m2 i.v. on days 1, 2 and 3, and continuous infusion of cytarabine 100 mg/m2/24 h from day 1 to 10. Forty-nine patients (68%) presented at least one of the following symptoms: acral erythema with dysesthesias in the palms and/or soles (39%); cholestatic hepatitis (39%); profuse sterile diarrhea associated with abdominal distention (33%); acute cerebellar dysfunction (32%) and non-cardiogenic pulmonary edema (21%). Most of these toxic symptoms appeared 8-20 days after the first dose. As these clinical features were absent or exceptional in patients treated with another regimen within a controlled trial, they are reported as toxic-side-effects of the chemotherapy regimen. Acral erythema was found to be predictive of complete remission (P less than 0.01, odds ratio: 6.33); neurotoxicity was prognostic for death in aplasia (P less than 0.05); the absence of any of the five symptoms was associated with failure of the induction regimen (P less than 0.02).

Skin reactions related to hand hygiene and selection of hand hygiene products.

BACKGROUND: In October 2004, The World Health Organization (WHO) launched the World Alliance for Patient Safety. Within the alliance, the first priority of the Global Patient Safety Challenge is to reduce health care-associated infection. A key action within the challenge is to promote hand hygiene in health care globally as well as at the country level through the campaign "Clean Care is Safer Care." As a result, the WHO is developing Guidelines on Hand Hygiene in Health Care, designed to be applicable throughout the world. METHODS: This paper summarizes one component of the global WHO guidelines related to the impact of hand hygiene on the skin of health care personnel, including a discussion of types of skin reactions associated with hand hygiene, methods to reduce adverse reactions, and factors to consider when selecting hand hygiene products. RESULTS: Health care professionals have a higher prevalence of skin irritation than seen in the general population because of the necessity for frequent hand hygiene during patient care. CONCLUSION: Ways to minimize adverse effects of hand hygiene include selecting less irritating products, using skin moisturizers, and modifying certain hand hygiene practices such as unnecessary washing. Institutions need to consider several factors when selecting hand hygiene products: dermal tolerance and aesthetic preferences of users as well as practical considerations such as convenience, storage, and costs.

Occupational hand infections.

Prompt diagnosis and treatment of hand and upper extremity infections is imperative because they have the potential to be life threatening and pose a risk of functional impairment. Serious infections may result in prolonged hospitalization and resultant loss of productivity. The mainstay of treatment continues to be antibiotic therapy, heat, elevation, adequate surgical drainage, and débridement. Prompt specialty consultation should be obtained in cases in which there is a doubt about the diagnosis or when there is failure to improve in the face of seemingly appropriate treatment.

Childhood nail diseases.

The diagnosis of pediatric nail populations is complicated because a large proportion of pediatric nail presentations involve parents bringing in their children with questions regarding nail appearance rather than the plain presentation of a disease or functional problem. Parents are concerned whether the nails are normal, if they are uncomfortable for the baby or child, if the nails will affect walking or other future function, or if the changes are of wider significance and suggest more sinister medical problems than are yet apparent. To address these concerns, the clinician needs a good grasp of what is normal.

Diagnosing onychomycosis.

Onychomycosis is the most prevalent nail disease, representing nearly half of all clinically diagnosed onychopathies. Given the pervasive nature of the disease and that successful treatment depends on the proper identification of the causative organism,accurate and reliable methods of diagnosis are necessary. This article discusses the efficacy of the various methods used for the diagnosis of onychomycosis.

Spotlight on nail histomycology.

The misdiagnosis of onychomycosis delays the proper treatment of the nail condition. Nail histomycology refers to the microscopic examination of histologic sections prepared from nail clippings for the purpose of detecting the presence of fungi. This laboratory method is the most sensitive procedure for the diagnosis of onychomycosis. It allows for the visualization of the precise location of the invasive fungus inside the nail apparatus. The method also distinguishes various shapes of the fungal cells, in particular filamentous fungi, yeasts, conidia, and sporodochia. The correct diagnosis provided by histomycology combined with culture not only allows for more efficient expenditure of funds and services but also is important for the timely alleviation of the disorder.

Efficacy of an alcohol-based healthcare hand rub containing synergistic combination of farnesol and benzethonium chloride.

Healthcare workers are required to disinfect the hands several times a day using hand disinfectants, which leads to chronic hand exposure to high levels of antimicrobials contained in the disinfectants, which could compromise the skin integrity. This problem may be addressed by developing hand disinfectants containing synergistic combinations of small amounts of antimicrobials and other agents. The synergistic effect of farnesol and essential oils with several antimicrobials was studied in vitro to select an effective antimicrobial system in preservative concentration for use in healthcare hand rub. Farnesol and lemon oil showed synergistic activity against S. aureus, in combination with benzalkonium chloride and benzethonium chloride, but not with other antimicrobials studied. All essential oils studied showed synergy with benzethonium chloride against Staphylococcus aureus and Escherichia coli. An alcohol-based healthcare hand rub (ZBF hand rub) containing this unique synergistic combination of farnesol and benzethonium chloride was then developed and its efficacy as a healthcare hand rub was evaluated in human volunteers according to the US FDA-TFM protocol using Serratia marcescens as a marker organism. The ZBF hand rub showed a 3.22 log(10) reduction in the microbial count after the first application and a 5.49 log(10) reduction after the tenth application in vivo and exceeds the US FDA-TFM criteria for healthcare hand rub. The ZBF hand rub did not irritate the hands when tested on human volunteers when applied 10 times everyday for five consecutive days. The ZBF hand rub exhibits more than 5.5 log(10) reduction in the microbial count within 15s and more than 2.8 log(10) reduction in the two types of viruses tested within 30s in vitro. When evaluated in an in vitro pig skin model, the ZBF hand rub shows better prolonged activity (20-35 min post-application) against transient bacteria (S. aureus and E. coli) compared to other alcohol-based hand rubs. These findings suggest that the use of the ZBF hand rub amongst health care workers may lower the risk of chronic hand exposure to high levels of antimicrobials without compromising the efficacy.

Necrolytic acral erythema: a cutaneous sign of hepatitis C virus infection.

BACKGROUND: Hepatitis C virus (HCV) infection is globally epidemic. Several mucocutaneous diseases are well established in association with HCV infection. Few case reports describe the recently recognized HCV-related skin disorder termed necrolytic acral erythema (NAE). METHODS: Thirty patients with NAE were identified in a university-based dermatology clinic in Cairo, Egypt. These patients were observed over time to document the clinical and histologic findings of this disorder. RESULTS: All patients were infected with HCV. Erythematous papules arose most commonly on the dorsal aspect of the feet, particularly the dorsal surface of the great toe. Progression resulted in confluence into erythematous dusky plaques with adherent scale and central erosion. The eruption extended to involve the lower leg and other regions in some patients but never affected palms or soles, the nail bed, nail plate, or mucous membranes. Skin biopsy specimens from fully evolved lesions displayed psoriasiform changes in association with more characteristic findings of keratinocyte necrosis and papillomatosis. LIMITATIONS: We did not perform a prospective review of patients known to be infected with HCV. Patients were identified from a general clinic population and then assayed for HCV serology. CONCLUSIONS: NAE is a distinctive skin disorder associated with HCV infection in all cases reported to date. Recognition of this disease should alert practitioners to the need for viral testing and appropriate counseling of patients.

Self-healing juvenile cutaneous mucinosis: cases highlighting subcutaneous/fascial involvement.

BACKGROUND: Self-healing juvenile cutaneous mucinosis is a rare disease affecting young people characterized by transient cutaneous lesions and sometimes mild inflammatory symptoms. The deep dermal and subcutaneous features of this disorder have not yet been well described. OBJECTIVE: The purpose of our study was to present 3 cases of self-healing juvenile cutaneous mucinosis in which the histopathologic features caused diagnostic confusion between this disorder and proliferative fasciitis. METHODS: The study includes clinical and histologic findings of 3 patients, complemented by a literature review. RESULTS: The histologic descriptions of nodular lesions in self-healing juvenile cutaneous mucinosis reveal features of proliferative fasciitis, including a myxoid stroma and gangliocyte-like giant cells. LIMITATIONS: Self-healing juvenile cutaneous mucinosis is a rare condition and has not been frequently reported in medical literature. Our findings are based on the pathologic features of 3 patients. CONCLUSIONS: Our findings further elucidate the histologic features of self-healing juvenile cutaneous mucinosis and expand the differential diagnosis for entities in which gangliocyte-like giant cells are noted.

Elevated body mass index does not increase the risk of palmar-plantar erythrodysesthesia in patients receiving pegylated liposomal doxorubicin.

OBJECTIVES: The dose-limiting toxicity of pegylated liposomal doxorubicin (PLD) is palmar-plantar erythrodysesthesia (PPE). Some physicians are reluctant to use this drug in overweight patients, postulating that larger size increases the likelihood of PPE. We sought to determine whether a correlation exists between body mass index (BMI) and the frequency or severity of skin reactions during PLD chemotherapy. METHODS: The records of all patients receiving PLD chemotherapy for gynecologic malignancy at our institution were reviewed for chemotherapy history, BMI at start of treatment, dose, infusion time, and adverse outcomes. Skin reaction sites, grade, and treatments were recorded. Possible predisposing factors were extracted, as well as the reason for drug discontinuation. RESULTS: Over 7 years, 103 patients were treated with PLD for gynecologic malignancies. 429 cycles were given, and PPE occurred in 36% of patients treated. Of those with PPE, reactions were grades 1, 2, or 3 in 54%, 32%, and 14% of patients, respectively. The BMI of patients with PPE (29.0) was not significantly different from that of patients without PPE (28.8). Analysis using finer subsets of weight also revealed no association. Finally, logistic regression revealed no relationship between BMI and rash grade. CONCLUSIONS: Elevated BMI does not appear to correlate with occurrence of PPE in our population. Of interest, among patients discontinuing PLD due to skin toxicity, 25% had clinical evidence of response. The identification of predisposing risk factors may help guide treatment decisions; however, elevated BMI does not appear to be such a risk factor.

Comparison of different regimens for surgical hand preparation.

Twenty surgical staff members participated in a clinical trial to compare the microbiology and skin condition of hands when using a traditional surgical scrub (TSS) with a detergent-based antiseptic containing 4% chlorhexidine gluconate (CHG) and a short application without scrub of a waterless hand preparation (HP) containing 61% ethyl alcohol, 1% CHG, and emollients. The HP was associated with less skin damage (P = .002) and lower microbial counts postscrub at days five (P = .002) and 19 (P = .02). The HP protocol had shorter contact time (HP mean [M] = 80.7 seconds; TSS M = 144.9 seconds; P < .0001), and more subjects preferred the HP regimen (P = .001). The HP performed better than the TSS, was less costly, and should be evaluated in larger trials and considered for widespread implementation.
