DERMATOLOGIC SURGERY, Issue 11 2001
Sorin Eremia MD
Background. Hypertrichosis is a common problem for which laser hair removal is becoming the treatment of choice. Optimal wavelength, pulse duration, spot size, fluence, and skin cooling parameters for various skin types have not yet been firmly established. Objective. To evaluate the long-term efficacy and safety of a 3-msec 755 nm alexandrite laser equipped with a cryogen cooling device for patients with Fitzpatrick skin types I,V. Methods. Eighty-nine untanned patients with skin types I,V underwent a total of 492 treatments of laser hair removal over a 15-month period. Each patient in the study underwent a minimum of three treatment sessions spaced 4,6 weeks apart (mean treatments 5.6). Retrospective chart review and patient interviews were used to establish hair reduction results. Treatment sites included the axillae, bikini, extremities, face, and trunk. A 3-msec pulse width, 755 nm alexandrite laser equipped with a cryogen spray cooling device was used in this study. Spot sizes of 10,15 mm were used. A spot size of 10 mm was used for fluences greater than 40 J/cm2, a spot size of 12 mm was used for fluences of 35,40 J/cm2, and spot sizes of 12 and 15 mm were used for fluences less than 30 J/cm2. Fluences ranging from 20 to 50 J/cm2 (mean fluence 36 J/cm2) were used. Results. The patients had a mean 74% hair reduction. Skin type I patients had an average of 78.5% hair reduction using a mean fluence of 40 J/cm2 (35,50 J/cm2) and a 10,12 mm spot size (12 mm in more than 95% of treatments). Skin type II patients had a mean 74.3% hair reduction using a mean fluence of 38 J/cm2 (30,40 J/cm2) and a 12,15 mm spot size. Skin type III patients had a mean 73.4% hair reduction using a mean fluence of 37 J/cm2 (25,40 J/cm2) and a 12,15 mm spot size. Skin type IV patients had a mean 71.0% hair reduction using a mean fluence of 31 J/cm2 (25,35 J/cm2) and a 12,15 mm spot size. A patient with skin type V had a 60% hair reduction using a mean fluence of 23 J/cm2 (20,25 J/cm2) and a 12,15 mm spot size. The efficiency of hair removal directly correlates significantly with the fluence used. Rare side effects included transient postinflammatory hyperpigmentation (n = 9; 10%), burn with blisters (n = 1; 1%), and postinflammatory hypopigmentation (n = 2; 2%). All complications resolved without permanent scarring. Conclusion. The 3-msec cryogen cooling-equipped alexandrite laser can safely and effectively achieve long-term hair removal in patients with skin types I,V. The best results are achieved in untanned patients with skin types I,IV. [source]


Necrotizing vasculitis in a patient affected by autoimmune hyperthyroidism treated with propylthiouracil

DERMATOLOGIC THERAPY, Issue 2010
Angela Antonucci
ABSTRACT Necrotizing vasculitis is a complex phenomenon because of an inflammation of small and larger vessels with polymorph infiltration within the vessel walls and leukocytoclasis, occurring in several autoimmune diseases. Propylthiouracil (PTU) is a medication commonly used to treat hyperthyroidism, but it is associated with various rare side effects, such as antineutrophil cytoplasm antibody-positive vasculitis. In the last decades, multiple cases of PTU causing antineutrophilic cytoplasmic antibody have been reported, some of them fatal. The present authors report the case of a 34-year-old Caucasian female affected by autoimmune hyperthyroidism treated with PTU, presenting an antineutrophil cytoplasm antibody-positive necrotizing vasculitis, with high levels of anticardiolipin antibodies that involved the upper arms and buttocks. The clinical manifestations improved after discontinuing of PTU and immunosuppressant treatment. [source]


Antenatal home blood pressure monitoring: a pilot randomised controlled trial

H. Ross-McGill Research Midwife
Objective To measure recruitment to, compliance with, and the acceptability of a trial designed to test whether a reduced schedule of antenatal visits combined with training in self-measurement of blood pressure at home may improve hypertension screening and save money. To test the specific hypothesis that even after taking into account extra unscheduled visits, the reduced schedule with ambulatory monitoring reduces total visits. Design A pilot randomised controlled trial. Setting Four urban and four rural general practices in Yorkshire and Lancashire. Population One hundred and five low risk women in the third trimester of pregnancy. Eighty women participated. Intervention Women were invited to participate at 24,28 weeks. Those who accepted were allocated either to a standard nine subsequent visit schedule (30, 32, 34, 36, 37, 38, 39, 40, 41 weeks) or to a reduced schedule (34, 38, 41 weeks). Those in the latter group measured their blood pressure weekly using a portable sphygmomanometer at home. Main outcome measures Recruitment, total number of clinic visits, frequency of blood pressure measurement, schedule preference, and anxiety. Results Although there were more unscheduled visits in the home monitoring group, this did not outweigh the reduction in scheduled visits, (total visits reduced from 7.4 to 4.5, P < 0.001), and blood pressure was measured during more weeks (9 vs 7 weeks, P < 0.001) in the experimental group. Most women expressed a preference for the reduced schedule both when the idea was first suggested, and after they had experienced it, and there were no significant differences in anxiety. Conclusion Replacement of antenatal screening visits with home blood pressure monitoring is acceptable to women. The reduction in clinic visits is not compensated by an increase in visits for other reasons and overall blood pressure measurement is omitted less often. Whether it reduces adverse outcomes or has any rare side effects will require a larger trial, but this pilot study indicates that it is likely to be safe, and that such a large trial would be feasible.

Stroke after initiation of interferon-beta treatment for relapsing,remitting disseminated white matter disease

ACTA NEUROLOGICA SCANDINAVICA, Issue 6 2006
B. Bosche
Background,,, Interferon-beta (INF- ,) is effective and used in reducing exacerbation frequency and disease progression in multiple sclerosis. In certain circumstances, INF- , can lead to rare side effects. Aims of the study,,, We report the case of a 34-year-old female patient satisfying the McDonald criteria of multiple sclerosis without showing typical pathologic changes in cerebrospinal fluid (CSF). After introduction of INF- , treatment, she quickly developed further progression of her disseminated neurological symptoms and finally an ischemic cerebral infarction. Methods,,, Evaluation of the patient included arterial angiography, magnetic resonance and positron emission tomography, histopathological assessment as well as a broad spectrum of serum and CSF analysis. Results,,, All diagnostic evaluations and the clinical course revealed evidences for a primary angiitis of the CNS. We discuss the possible worsening due to inappropriate INF- , treatment in cerebral angiitis promoting severe cerebrovascular insufficiency. Conclusion,,, The authors suggest that all diagnostic multiple sclerosis criteria including typical CSF findings should be ascertained before INF- , treatment is initiated. [source]
