Antitumor necrosis factor-induced neutropenia: a case report with double positive rechallenges

A 50-year-old man with ankylosing spondylitis who developed neutropenia after treatment of etanercept, with two positive rechallenges, and after the first infliximab infusion, is described. Although leukopenia and neutropenia related to etanercept and infliximab have been described as rare adverse events from clinical trials data, their mechanism of action are unknown. This patient developed recurrent mild neutropenia after exposition of two different antitumor necrosis factors; therefore, it seems to be an adverse reaction related to the therapeutic group. Doctors should be aware of this potentially severe adverse effect in patients treated with antitumor necrosis factor.

[Nosocomial infections due to opportunistic fungi: analysis of a news outbreak in the Spanish press]

BACKGROUND

To study an outbreak of media news related to nosocomial infections due to opportunistic fungi in Spanish hospitals.

METHOD

CASE DEFINITION

any news related to possible nosocomial infection due to opportunistic fungi in Spanish hospitals, published in national or local daily newspapers, over the pre-epidemic (July-December, 1998) and epidemic periods (January-June, 1999). All news were reviewed and identified using global press reports summaries, prepared by two independent sources, and were analyzed by three different observers.

RESULTS

Over the pre-epidemic period there were not any news related to nosocomial infections due to opportunistic fungi. Over the epidemic period, a total of 218 news were identified, 154 (71%) published in national newspapers and 64 (29%) in local ones. We analyzed separately 18 editorials or opinion articles related to this subject. The epidemic curve (distribution of news by week) showed an incidence news peak at week 5 (102 news, 46.7% of all news published). The media mentioned up to 19 different hospitals as institutions with possible cases of nosocomial fungal infections. After week 8, news incidence drop, and remain thereafter at minimum levels.

CONCLUSIONS

The example provided by the analysis of this outbreak of media news, related to nosocomial infections by Aspergillus an other opportunistic fungi, is useful to allow us understand how some medical news arise, develop and were transmitted. The public alert situation created in Spain was remarkable, and it is likely that there was a transient loss of confidence in the safety of public health institutions. Today's medicine requires a great and better openness to the media, and a better cooperation between both parts.

Handwashing with soap or alcoholic solutions? A randomized clinical trial of its effectiveness

BACKGROUND

The effectiveness of an alcoholic solution compared with the standard hygienic handwashing procedure during regular work in clinical wards and intensive care units of a large public university hospital in Barcelona was assessed.

METHODS

A prospective, randomized clinical trial with crossover design, paired data, and blind evaluation was done. Eligible health care workers (HCWs) included permanent and temporary HCWs of wards and intensive care units. From each category, a random sample of persons was selected. HCWs were randomly assigned to regular handwashing (liquid soap and water) or handwashing with the alcoholic solution by using a crossover design. The number of colony-forming units on agar plates from hands printing in 3 different samples was counted.

RESULTS

A total of 47 HCWs were included. The average reduction in the number of colony-forming units from samples before handwashing to samples after handwashing was 49.6% for soap and water and 88.2% for the alcoholic solution. When both methods were compared, the average number of colony-forming units recovered after the procedure showed a statistically significant difference in favor of the alcoholic solution (P <.001). The alcoholic solution was well tolerated by HCWs. Overall acceptance rate was classified as "good" by 72% of HCWs after 2 weeks use. Of all HCWs included, 9.3% stated that the use of the alcoholic solution worsened minor pre-existing skin conditions.

CONCLUSIONS

Although the regular use of hygienic soap and water handwashing procedures is the gold standard, the use of alcoholic solutions is effective and safe and deserves more attention, especially in situations in which the handwashing compliance rate is hampered by architectural problems (lack of sinks) or nursing work overload.

[Scrotal granuloma caused by oil migrating from the hip in 2 transsexual males (scrotal sclerosing lipogranuloma)]

OBJECTIVE

To describe two patients with scrotal granuloma due to silicone oil migrated from the hip.

METHODS/RESULTS

Two male transsexuals without genitoplasty developed scrotal inflammatory masses after subcutaneous injection of silicone oil to remodel the hip contour. Imaging studies and pathologic examination disclosed lesions similar to those encountered in ruptured silicone breast implants.

CONCLUSIONS

Silicone migration to the scrotum through subdermal fascial planes can cause a granulomatous lesion similar to that of ruptured breast implants. The migratory pathway is similar to that of scrotal emphysema and, inversely, the dissemination of necrotizing fasciitis of the genitalia.
