Genital psoriasis: a questionnaire‐based survey on a concealed skin disease in the Netherlands

Background Psoriatic lesions may involve nearly all sites of the body. Involvement of the genital skin is frequently classified as part of intertriginous psoriasis without special awareness and treatment for this presentation of the disease. Gaining knowledge about the frequency of the involvement of genital skin in these patients will improve the overall care for patients with psoriasis. Objectives We studied the prevalence of genital psoriasis in the Netherlands and epidemiological characteristics of this specific presentation of the disease. Furthermore, we studied the relation between flexural and genital psoriasis. Patients/Methods A self‐administered questionnaire was sent to all 5300 members of the Dutch Psoriasis Society. Sociodemographic patient characteristics and disease‐related data (such as localization of psoriatic lesions, involvement of the genitalia, age at onset of genital psoriasis and severity of genital psoriatic lesions) were collected and analysed. Results A response rate of 37% was achieved. Almost 46% of the responding patients with psoriasis, that is 16.5% of all potential responders (n = 5300), report genital involvement at some time during the course of their disease. The genitalia can become affected at any age. Many patients with current genital involvement (38%) do not have the flexural skin affected. Conclusions A large part of patients with psoriasis suffer from genital psoriasis, which was not associated with flexural involvement in at least one third of them. More attention to the genital region is required in the current standard treatment of both male and female psoriatic patients at any age.

Latanoprost-associated recurrent herpes simplex keratitis

PURPOSE/METHOD: We present a case of a patient who developed recurrent epithelial herpes simplex keratitis after starting treatment with latanoprost. Her ophthalmic history was only remarkable for a past episode of herpetic keratitis 21 years previously. RESULTS/CONCLUSIONS: Episodes of herpetic keratitis were under remission only when latanoprost was discontinued. No recurrences of herpes simplex keratitis have been observed since then. Latanoprost usage might be associated with recurrent episodes of herpes simplex keratitis in patients with previous history of ocular herpes simplex virus infection.     

Peripheral multineuritis pointing at systemic sarcoidosis

We report a patient with a peripheral neuropathy as the first symptom of sarcoidosis. The systemic illness was proved by the presence of typic granulomes in the bone marrow. The fact that sarcoidosis is the cause for the neuropathy is supported by the temporary relation and by the good response of all clinical picture to the corticosteroid therapy.Sarcoid neuropathy can rarely be the presenting feature of sarcoidosis.     

山苍子水提物柠檬醛抗哮喘作用的实验研究

目的：研究山苍子水提物柠檬醛的抗哮喘作用及其机理。方法：通过豚鼠氯化乙酰胆碱-磷酸组胺喷雾致喘法、小鼠浓氨水喷雾引咳法、小鼠酚红排泻法观察柠檬醛的平喘、镇咳、祛痰作用，通过观察张力变化研究柠檬醛对豚鼠离体气管环张力的影响及乙酰胆碱对气管收缩的抑制作用。结果：柠檬醛能明显延长氯化乙酰胆碱-磷酸组胺喷雾引起的豚鼠哮喘潜伏期，能延长浓氨水喷雾诱发小鼠咳嗽反应潜伏期，明显减少咳嗽次数。能增加小鼠呼吸道酚红排泌量，能抑制乙酰胆碱对豚鼠离体气管平滑肌的收缩作用，使乙酰胆碱所致气管平滑肌量效曲线右移。结论：柠檬醛气雾剂具有一定的平喘、镇咳和祛痰作用，具有良好的支气管解痉作用。     

Variability of results of cavernous nerve stimulation during radical prostatectomy

PURPOSE: We assess the reliability of intraoperative cavernous nerve stimulation for producing an erectile response during radical prostatectomy. MATERIALS AND METHODS: In 61 patients cavernous nerve function was assessed during radical retropubic prostatectomy using a CaverMap nerve stimulator. Control stimulation was also performed before and after prostatic dissection by placing the nerve stimulator tip on the anterior bladder wall. An increase in penile circumference measured by the device was considered a tumescence response while any measurable detumescence was also categorized. RESULTS: Patient age ranged 43 to 72 years (mean 59.8). Before apical dissection 41% and 46% had tumescence, 31% and 21% had detumescence, and 28% and 33% had no response with stimulation of the neurovascular bundle and anterior bladder wall, respectively. After dissection 42% and 25% had tumescence, 16% and 18% had detumescence, and 42% and 57% had no response with stimulation of the neurovascular bundle and anterior bladder wall, respectively. CONCLUSIONS: A response to neurovascular bundle stimulation using this device does not necessarily correlate with the precise anatomical location of the cavernous nerves. There is considerable background variability related to anesthesia, surgical manipulation and other undefined factors that may cause minor but measurable changes in penile circumference.
