In patients with the adrenogenital syndrome, a single intramuscular injection of 40 mg every two weeks may be adequate. For maintenance of patients with rheumatoid arthritis , the weekly intramuscular dose will vary from 40 to 120 mg. The usual dosage for patients with dermatologic lesions benefited by systemic corticoid therapy is 40 to 120 mg of methylprednisolone acetate administered intramuscularly at weekly intervals for one to four weeks. In acute severe dermatitis due to poison ivy, relief may result within 8 to 12 hours following intramuscular administration of a single dose of 80 to 120 mg. In chronic contact dermatitis, repeated injections at 5 to 10 day intervals may be necessary. In seborrheic dermatitis, a weekly dose of 80 mg may be adequate to control the condition.
Epidemiology. Findings regarding prevalence rates depend on the methodology employed, the sample under study, how PD is defined, and how men are queried with ranges from % to % within specific populations. Using a population-based methodology in a . sample aged 18 years and older, Dibenedetti (2011) reported a prevalence rate of % for men who had been formally diagnosed with PD, a rate of % for men who had been diagnosed or treated for PD, and a rate of % for men who had been diagnosed or treated or had any symptom of PD. 12 Schwarzer (2001) conducted a community-based study among men in Cologne, Germany and reported a prevalence rate of % in men aged 31-78 years. 13 Another population-based study in Italian men reported a prevalence rate of % among men aged 50-69 years. 14 Among men older than age 40 years screened for prostate cancer in the ., a prevalence of % was reported. 15 Men older than 50 years screened for prostate cancer in Southern Brazil had a prevalence rate of %. 16 Rates may be higher among men who present with comorbidities. El-Sakka (2006) reported a prevalence rate of % among men who presented with ED. 17 Arafa (2007) reported a rate of % among men who were diabetic with ED. 18 Together, this group of studies suggests that prevalence rates historically have been under-estimated. The higher rates detected in more recent studies suggest a greater awareness of the disease and its symptoms.
