Adverse effects of isolation: a prospective matched cohort study including 90 direct interviews of hospitalized patients in a French University Hospital.

Isolation precautions in patients with multi-drug resistant bacteria or other communicable infectious agents can be associated with adverse effects. The aim of this study was to assess satisfaction and psychological impact of patients hospitalized with isolation precautions in comparison with controls. An observational prospective cohort study was performed in five different medical and surgical departments in a 3,000-bed university hospital in Western France between March and July 2012. Different scales were used to assess patient satisfaction (qualitative scale) and anxiety (Spielberger scale), including 30 patients with isolation precautions and 60 matched patients without isolation precautions over 45-hour interviews. Cases were significantly less satisfied than controls for healthcare workers (HCW) assistance in activities of daily life (p < 0.001), availability and relationships (17 % vs 5 %, p = 0.05 and 10 % vs 0%, p = 0.02, respectively). Sixty-seven percent of patients with isolation precautions were not satisfied about the quality of the information related to their infectious status control measures. The median score [range] of anxiety significantly was higher in patients with isolation precautions (52 [20-56] vs 31 [23-73], p <0.001). Isolation precautions may have negative psychological effects, leading to anxiety, and may compromise patient satisfaction according to the availability and relationship with HCW. Professionals should be aware of adverse effects of isolation and inform patients more actively with regard to their infectious status and precautions.

[Extensive digital necrosis during dermatomyositis associated with MDA-5 antibodies]. / Nécroses digitales étendues au cours d'une dermatomyosite avec anticorps anti-MDA-5.

BACKGROUND: Dermatomyositis (DM) is an inflammatory disease associated with auto-antibodies in 50 to 70% of cases. A new antibody, anti MDA-5, has been described in association with a specific type of DM involving severe interstitial lung disease and minimal muscle disease. We report the first case of DM with MDA-5 antibodies and with interstitial lung disease and rapidly extensive digital necrosis. PATIENTS AND METHODS: A 28-year-old male was hospitalized for asthenia, myalgia and subacute dyspnea. Examination demonstrated skin lesions with edema on every digit associated with purpuric and cyanotic lesions, as well as erythematous papules on the helix and the elbows, and Gottron's papules. Systemic corticosteroid therapy was initiated. The immunoprecipitation results indicated the presence of anti-MDA-5 antibodies. Despite corticosteroid therapy, the patient's respiratory status gradually deteriorated towards pulmonary fibrosis and rapidly extensive necrosis appeared on all fingers and toes. Theses effects were resistant to cyclophosphamide and immunoglobulin but were stabilized by cyclosporine. DISCUSSION: Anti-MDA-5 antibodies are specific to DM and constitute a risk factor for severe interstitial lung disease (70% of cases) with a higher risk of mortality (40%). The cutaneous presentation of this DM is specific with palmar papules and mucocutaneous ulceration. Rapidly extensive digital necrosis has not been previously reported. No treatment has demonstrated superiority. CONCLUSION: We report the first case of DM with anti-MDA-5 antibodies involving interstitial lung disease and massive digital necrosis. Because of the pulmonary risk, in the presence of clinical lesions containing anti-MDA-5 DM, screening for these antibodies should be carried out.

[Pseudocyst of the scalp: two cases]. / Pseudo-kystes du cuir chevelu : deux cas.

BACKGROUND: Pseudocysts of the scalp are a poorly known entity. Herein we present two new cases. CASE REPORT: Two male patients aged respectively 42 and 33 years had been presenting a small number of pseudocystic lesions on the scalp, as well as alopecia limited to the same region, for a number of years. Inflammatory episodes had occurred in certain lesions. In one case, biopsy showed an aspect typical of pseudocyst of the scalp and the lesions appeared to stabilize on treatment with doxycycline. DISCUSSION: Pseudocysts of the scalp are also known as aseptic nodules of the scalp, a term that appears to us to be less appropriate. They form lesions involving alopecia and they may be inflammatory to various degrees. Following incision of these lesions, a deep yellow fluid liquid is released that may be shown by microbiological analysis to be sterile. Histological analysis reveals a pseudocystic wall associated with perilesional inflammatory remodelling. The cysts are frequently confused with dissecting cellulitis of the scalp, but the prognosis is more encouraging. Treatment involves surgical excision, and intralesional injections of corticosteroids or doxycycline.

[Melanoma of the anal margin]. / Mélanome de la marge anale.

BACKGROUND: Primary anal mucosal melanoma is rare and is associated with a poor prognosis. The observation of a case of anal melanoma at a localized stage in a woman led us to analyze recent data from the literature on therapeutic alternatives. PATIENTS AND METHODS: A 49-year-old woman presented with a pigmented swelling of the anal margin that had begun three months earlier. Complete local excision of the tumour was performed with the conservation of the anal sphincters. Histological examination revealed SSM mucosal melanoma. Abdominoperineal resection was finally performed because of tumoural invasion of the lateral margins. Staging assessment was normal. Half-yearly MRI monitoring of the pelvis was proposed and at nine months no relapse was seen. DISCUSSION: The unusual and misleading symptoms often account for the late diagnosis and poor prognosis of anal melanoma. Treatment is not well defined: local excision with conservation of the anal sphincters is recommended as first-line therapy, but the surgical technique is controversial. Abdominoperineal resection is recommended if the surgical margins are invaded, in the case of local recurrence or if the tumour is inaccessible. The place of adjuvant therapies remains to be defined. More recently, the discovery of mutation in c-KIT mucosal melanoma has allowed the use of biotherapy. Our observation underscores the importance of early detection of anal melanoma by all practitioners concerned in view of its aggressiveness and we report the difficulties of therapeutic management in the absence of established guidelines.
