摘要:

Genetic skin diseases are usually thought of as stable phenotypes caused by a mutant gene. However, a review of the literature on genodermatoses and my personal experience with a number of these disorders show that the concept of a stable phenotype is not always true. A number of genodermatoses actually show a regression of symptoms. Among these are monilethrix, several types of erythrokeratoderma, several forms of palmoplantar keratoderma such as the varians Wachters type and the Richner-Hanhart syndrome, and some forms of epidermolysis bullosa, for example the Dowling-Meara type. Three different reasons possibly underlying the regression of symptoms in genetic diseases are briefly discussed: (1) environmental factors, (2) hormonal influences and (3) movable, transposable elements causing instability of the genome.

摘要:

We report on 3 patients who developed a generalized eczematous skin rash under treatment with simvastatin and pravastatin for hypercholesterolemia. These drugs are 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors and suppress cholesterol synthesis in the liver. Based on experimental data from the literature that showed eczematous changes in mice treated topically with the HMG-CoA reductase inhibitor lovastatin, we suspect that the rash observed in our patients may be a consequence of skin barrier dysfunction following inhibition of cholesterol biosynthesis.

摘要:

Two consecutive studies were performed with the aim of clearly defining the optimal physical treatment for closed comedones. The first 10 patients with clinically significant numbers of facial comedones were treated with fulguration under EMLA® anaesthesia on one side of the face and topical tretinoin on the opposite side. At the end of the study fulguration was shown to be significantly (p = 0.005) superior to topical tretinoin. A direct comparison of light electrocautery using EMLA anaesthetic with fulguration without anaesthesia was then performed on 12 patients. The comedones were subdivided by size into those that were approximately 1 mm or less in diameter and those of greater dimensions. In the treatment of larger comedones electrocautery was shown to be significantly superior to fulguration (p = 0.025), but there was no significant difference in the efficacy of the treatments for the smaller lesions

摘要:

We studied the workload of the general practitioner after two skin cancer screening clinics in the Netherlands. Thirty-one physicians participated in the project. The numbers of patients presenting with benign and malignant skin lesions were recorded 2 weeks before and 6 weeks after the public campaigns. In the week immediately after the screenings there was a small increase in the number of consultations for suspected skin cancer. Thereafter, the weekly number of malignant lesions decreased to precampaign levels. Subsequently to the campaigns the numbers of referrals for benign skin lesions decreased slightly. We conclude that the extra workload for the general practitioner generated by the screening campaigns has been negligible.

摘要:

We report the case of a previously healthy 54-year-old woman, without any family history, who developed an angioneurotic edema with acquired C1 inhibitor deficiency and systemic lupus erythematosus. The search for a lymphoproliferative disorder was negative. Hydroxychloroquine therapy induced simultaneous resolution of lupus and angioedema. The pathophysiology of this association is discussed.

摘要:

A case of acute subcutaneous emphysema of the lateral region of the neck is described. The patient, a 26-year-old woman, also had radiologic evidence of pneumomediastinum. She completely recovered in a few days under prophylactic antibiotherapy. In this case, subcutaneous and mediastinal emphysema was most probably due to the introduction of air into the soft tissue during dental surgery using compressed air equipment.

摘要:

We report the case of a 47-year-old male with Kartagener’s syndrome (KS; situs inversus, bronchitis and sinusitis) who showed three types of cutaneous lesions: recurrent outbreaks of nummular eczema, recurrent deep folliculitis and two episodes of pyoderma gangraenosum. The patient had also IgA gammopathy of undetermined significance. This is the second case of KS associated with cutaneous lesions published so far and suggests that primary ciliary dyskinesia syndromes may have skin symptom
