Microdialysis-based 48-hour continuous glucose monitoring with GlucoDay: clinical performance and patients' acceptance.

BACKGROUND: This study was designed to assess clinical performance and patients' acceptance of the minimally invasive microdialysis-based continuous glucose monitoring system Gluco- Day() (Menarini Diagnostics, Florence, Italy) with a targeted monitoring time of 48 h. METHODS: An inpatient sample of 28 patients with diabetes was studied. The analysis of clinical performance was performed using mean absolute differences (MAD) (in percent), Pearson correlations, the Bland-Altman analysis, and Clarke Error Grid Analysis (EGA). GlucoDay glucose values were compared with laboratory standard blood glucose measurements (glucohexokinase assay). The patients' acceptance of the monitoring device was assessed via two self-report scales (pain during application and discomfort while wearing device). RESULTS: A mean (+/- SD) monitoring time of 45.7 +/- 3.3 h with a total of 484 paired readings could be achieved. A correlation of r (average) = 0.91 and a MAD of 19.9% indicated satisfactory to good clinical performance. Of the paired readings, 95.5% fell into the acceptable A and B zones of the EGA. Rather wide 95% limits of agreement were revealed in the Bland-Altman analysis. Whereas virtually no pain was experienced during sensor application, discomfort associated with wearing the device was rather high. All of the participants, however, stated that they would wear the device again. CONCLUSIONS: Satisfactory to good performance of the GlucoDay monitor was observed, indicating the device to be suitable for routine clinical use. In particular, however, the discomfort experienced during wearing requires further improvements in its usability.

[Lipoma of the forehead].

BACKGROUND AND OBJECTIVE: Lipomas should be included in the differential diagnosis of tumors located on the forehead. They require a different operative plan. PATIENTS/METHODS: Lipomas of the forehead were extirpated in ten patients. Dermatohistopathologic investigations confirmed the diagnosis lipoma in each case and exactly identified the anatomic layers surrounding the tumor. RESULTS: Histologic investigations revealed the localization of the lipoma in the submuscular layer in eight patients and in the subgaleal layer in two patients. CONCLUSIONS: Lipomas of the forehead should be differentiated into submuscular and subgaleal lipomas depending on the exact anatomic localization below the frontalis muscle or underneath the galea aponeurotica. This classification is simple and aids in operative planning.

Clear cell hidradenoma in a young girl.

Clear cell hidradenoma was diagnosed in a girl at 3(1/2) years of age. Only one case of hidradenoma has been documented in the first decade of life, although it remains unclear whether it was clear cell hidradenoma. This case demonstrates that clear cell hidradenoma is a rare differential diagnosis of cutaneous tumors even in young children, which is of special interest, because malignant transformations can occur.

Chronic ulcerative stomatitis.

Chronic ulcerative stomatitis (CUS) has recently been described as a new disease entity characterized by chronic ulceration of oral mucosa which responds to treatment with hydroxychloroquine. It has a particular type of stratified epithelium-specific, antinuclear autoantibody as an immunological marker. Twelve cases have been reported in the literature. We present a 40-year-old woman with an 11-year history of chronic oral ulcerations. Other dermatological diseases, including oral lichen planus, pemphigus vulgaris and cicatricial pemphigoid, as well as bullous lupus erythematosus, were excluded. The clinical diagnosis of CUS was confirmed on the grounds of the immunological and ultrastructural findings. The lesions initially responded to high doses of systemic corticosteroids but relapsed promptly after dose reduction. Dapsone was ineffective. Hydroxychloroquine, given at a dosage of 200-400 mg/day, led to a complete and long-lasting remission.

A nevoid plaque with histological changes of trichoepithelioma and cylindroma in Brooke-Spiegler syndrome. An immunohistochemical study with cytokeratins.

Brooke-Spiegler syndrome is characterized by the development of multiple trichoepitheliomas and cylindromas. In addition, multiple spiradenomas have been observed in this autosomal-dominant inherited disease. We report a 53-year-old woman with multiple cylindromas on the head and neck and multiple trichoepitheliomas on the face. Additionally, she had had since birth a plaque on the right side of her neck containing two nodules with features of both cylindroma and trichoepithelioma. Immunohistochemical investigations revealed in the basaloid cells of trichoepithelioma an expression of CK 5/6, CK 14, CK 17, CK 19 and vimentin. The cells of the cylindroma lacked vimentin but expressed additionally CK 7, CK 8 and CK 18. The occurrence of cylindroma and trichoepithelioma in a single nevoid plaque from a patient with Brooke-Spiegler syndrome implies an alteration in the stem cells of the folliculosebaceous-apocrine unit and could be characteristic of the disorder.

Cyclosporin in localized and systemic scleroderma--a clinical study.

Four patients with systemic scleroderma and 1 patient with localized scleroderma were treated with ciclosporin (CS), given in daily doses between 2.2 and 5.6 mg/kg body weight for 3-26 months. Under this medication clinical improvement was observed in 4 patients with partial regression of cutaneous sclerosis and inflammation, healing of fingertip ulcerations or leg ulcers and improvement of articular mobility. However, in 1 patient with rapidly advancing systemic scleroderma a short-term therapy with CS in low doses (2-3 mg/kg body weight) resulted in arterial hypertension and renal dysfunction. Therefore careful selection of patients and close-meshed controls are indicated when CS is considered as anti-inflammatory treatment in scleroderma.
