[Evaluation of the efficacy of dapoxetine in primary and secondary forms of premature ejaculation]

OBJECTIVE

to compare the efficacy of dapoxetine in treatment of primary and secondary premature ejaculation.

MATERIALS AND METHODS

The study included 60 patients with premature ejaculation (PE). Depending on the form of premature ejaculation they were divided into two groups: 27 patients with primary PE (group 1) and 33 patients with secondary PE (group 2). Patients were recommended to take dapoxetine 30 mg 1 hour before intercourse. A follow-up visit was scheduled on day 30 after receiving the drug. The intravaginal ejaculation latency time (IELT) and the Premature ejaculation diagnostic tool (PEDT) score were evaluated before dapoxetine was given and after 30 days from the start of the study. The significance of differences between baseline and follow-up values were compared using Wilcoxons test. In both groups, the proportion of patients with an incomplete response (IELT less than 2 minutes, PEDT more than 10) to symptomatic therapy with dapoxetine was evaluated. The proportion of patients with incomplete response to therapy was compared using the chi-square test.

RESULTS

The median IELT among all patients before starting therapy was 63 seconds (interquartile interval [IQR]: 28.75-94). After one month of therapy median IELT increased to 119 seconds (IQR: 58.75-321.75). Median PEDT score was 16 (IQR: 13-19) at baseline and 7 (IQR: 4-12) at follow-up. In group 1, the median IELT increased from 57 to 83 seconds (p = 0.02088), and in group 2, the median IELT increased from 70 to 173 seconds (p<0.00001). The mean PEDT score decreased to 7 in both groups (p<0.00001). Incomplete response to therapy was observed in 66.7% of patients in group 1 and in 39.4% of patients in group 2. The difference between two groups was statistically significant (p=0.035456).

CONCLUSION

Symptomatic therapy with dapoxetine has a positive effect on the intravaginal ejaculation latency time and patient satisfaction in both primary and secondary premature ejaculation. However, the incidence of incomplete response to therapy is higher in patients with primary premature ejaculation, which may be due to characteristic differences in the pathogenesis of primary and secondary premature ejaculation.

Copepods associated with a perirectal abscess and copepod pseudo-outbreaks in stools for ova and parasite examinations

We observed copepods, an intermediate host for several human parasites, in material obtained from a perirectal abscess of a 22-year-old man with Crohn's disease. We subsequently noted copepod "outbreaks" in stool specimens submitted for ova and parasite examination. Copepods in the hospital tap water supply were the source for one "outbreak".

Duration of rifampin chemoprophylaxis for contacts of patients infected with Haemophilus influenzae type B

Rifampin is recommended as a prophylactic treatment for intimate contacts of young children who develop invasive infections with Haemophilus influenzae type B (Hib). A 4-day course of rifampin (20 mg/kg of body weight per day, not to exceed 600 mg as a maximum single daily dose) is 95% effective in eradicating pharyngeal colonization with Hib, thus effectively reducing the risk of both associated patients and recurrent illness in index patients less than 2 years old. This study compares rates of eradication of pharyngeal colonization with Hib for 2- and 4-day courses of rifampin therapy. One hundred sixty-three patients with Hib infection were treated at Children's Hospital of Pittsburgh between January 1986 and December 1988; prophylaxis was recommended for 128. Participating families were randomized to receive either 2- or 4-day therapy. Throat swabs were obtained from contacts prior to therapy. Repeat cultures were obtained from colonized contacts 2 days after completing rifampin and again on all contacts 7 to 10 days after completing therapy. Of 68 participating families, 34 received 2-day and 34 received 4-day therapy with rifampin. Twenty-two of 24 colonized contacts in the 2-day group and 17 of 18 in the 4-day group had negative cultures for Hib on follow-up. Two-day therapy with rifampin appears to be as effective as 4-day treatment in the eradication of Hib pharyngeal colonization.

Electrocardiographic findings in children with Lyme disease

The incidence of cardiac involvement in Lyme disease (LD) has been estimated to be 4 to 10% in adults, with conduction and rhythm disturbances noted most frequently. To assess the frequency of electrocardiographic abnormalities in children with LD, we prospectively performed 12-lead electrocardiograms in 32 randomly selected children presenting with LD between May and September 1989. No patient had symptoms of cardiac involvement. Using defined diagnostic criteria, combining symptoms, signs, serology, and residence in or travel to an endemic area, 14 patients were classified as having definite LD and 10 were categorized as probable. The incidence of electrocardiographic abnormalities in the definite group was 29% (4/14), including two patients with 1 degree atrioventricular block, one with left axis deviation, and one with ventricular ectopy. Thirty percent (3/10) of the probable group had abnormal ECGs, including one with ST-T wave abnormalities, one with prominent sinus arrhythmia, sinus bradycardia, and wandering atrial pacemaker, and one with ectopic atrial bradycardia. No patient required cardiac therapy. The incidence of abnormal ECG findings in this group of children with either probable or definite LD was thus 29%, with 1 degree atrioventricular block noted most frequently. When the diagnosis of LD is highly suspected, an electrocardiogram may be a useful screening test for cardiac involvement.

Liver abscess caused by Clostridium bifermentans following blunt abdominal trauma

A case of hepatic abscess and subsequent septicemia caused by Clostridium bifermentans is described. The abscess manifested itself on the third day after blunt trauma to the torso. The patient had nausea, vomiting, fever, evidence of hepatic dysfunction, and subphrenic gas. This case illustrates the association of hepatic abscess and blunt trauma to the torso.

Haemophilus influenzae type b colonization in household contacts of infected and colonized children enrolled in day care

Strategies for management of children attending day-care facilities after a case of Haemophilus influenzae type b disease are controversial. The success of chemoprophylaxis in preventing subsequent cases has been variable. Failure of rifampin prophylaxis as currently recommended may result from usage limited to direct contacts of the index patient. This prospective study was designed to ascertain the extent of colonization in household contacts of colonized children attending day-care facilities with an index case of H influenzae disease. Outer membrane protein analysis was used to determine similarity between strains isolated from contacts and index patients. Of children attending six day-care facilities, 15% were colonized with subtypes of H influenzae identical with those of their respective index patients, and 7% of children were colonized with different subtypes. Colonization with identical outer membrane protein subtypes in children from day-care homes was more frequent than in the larger day-care centers (91% v 8%, P less than .00001). Within families of children with identical outer membrane protein subtypes, 25% of household members (17% of parents and 44% of siblings) were colonized despite lack of direct contact with the index patients. This colonization rate was comparable to that of household contacts of index patients (26%). Among household contacts of index patients, especially siblings, colonization with H influenzae tended to be lower if the patient attended day care than if the patient did not attend day care (17% v 73%; P = .05 for siblings). We have found that household contacts of colonized day-care children are a reservoir of H influenzae.(ABSTRACT TRUNCATED AT 250 WORDS)

Isolated uvulitis due to Haemophilus influenzae type b

Infections of the uvula are infrequently recognized and have been previously described only in association with group A streptococcal pharyngitis or Haemophilus influenzae type b epiglottitis. Three cases of H influenzae type b bacteremic uvulitis are described. In suspected cases of H influenzae type b uvulitis, a lateral neck radiograph should be performed and parenteral antibiotics initiated.
