The alarming trend of substance abuse in anesthesia providers.

The role of the anesthesia provider requires a high level of awareness and constant vigilance. Literature indicates, however, that the substance abuse rate in certified registered nurse anesthetists (CRNAs) and anesthesiologists has reached staggering levels. The literature also shows that there has been a change in which controlled drugs are being misused. It is imperative that perianesthesia nurses be aware of the current problem and take steps when indicated to protect both providers and patients. This article discusses the current trends of addiction in anesthesia providers, treatment, and reentry, as well as the role of the perianesthesia nurse in recognizing, reporting, and preventing substance abuse.     

Comparative study of the effectiveness of cefixime and penicillin V for the treatment of streptococcal pharyngitis in children and adolescents.

An open label randomized trial conducted in rural Kentucky compared the efficacy and safety of cefixime (CFX), 8 mg/kg once daily, with those of penicillin V (PEN), 250 mg 3 times daily, in 110 pediatric patients with Group A beta-hemolytic streptococcal pharyngitis. Forty-eight CFX and 47 PEN patients were evaluable for efficacy. At the end of therapy bacteriologic eradication was 45 of 48 (94%) and 36 of 47 (77%) in the CFX and PEN V groups, respectively (P < 0.05). Up to 6 weeks posttherapy 10 (21%) CFX patients and 21 (45%) PEN patients had positive Group A beta-hemolytic Streptococcus cultures (P < 0.05). Concordant serotypes were identified from 4 of 7 CFX and 15 of 17 PEN patients with positive repeat cultures. All discordant serotypes (5 of 31) were identified at greater than 19 days posttherapy. Symptomatic treatment failures (concordant serotypes) occurred in 1 (2%) CFX and 8 (17%) PEN patients (P < 0.05). Drug-related adverse experiences consisted of 2 cases of mild diarrhea and loose stools in the CFX group and none in the PEN group. No clinically significant laboratory test abnormalities occurred in either group. CFX, once daily, was as safe as and significantly more effective than PEN given 3 times daily for the treatment of Group A beta-hemolytic streptococcal pharyngitis.     

Retention of "safe" blood donors. The Retrovirus Epidemiology Donor Study

BACKGROUND: There are obvious advantages to increasing donor retention. However, for reasons of blood safety, certain donors may, in fact, be more desirable to retain than others. “Safe” donors are defined as those who provided a blood donation that was negative on all laboratory screening tests and who subsequently reported no behavioral risks in response to an anonymous survey. This study identifies the most important factors affecting the intention of “safe” donors to provide another donation. STUDY DESIGN AND METHODS: An anonymous survey asking about donation history, sexual history, injecting drug use, and recent donation experience was mailed to 50,162 randomly selected allogeneic donors (including directed donors) who gave blood from April through July or from October through December 1993 at one of the five United States blood centers participating in the Retrovirus Epidemiology Donor Study. Before mailing, questionnaires were coded to designate donors with nonreactive laboratory screening tests at their most recent donation. RESULTS: A total of 34,726 donors (69%) responded, with substantially higher response among repeat donors. According to reported intentions only, the vast majority of “safe” donors indicated a high likelihood of donating again within the next 12 months. Only 3.4 percent reported a low likelihood of donating again. A comparison of those likely to return and those unlikely to return reveals significant differences in demographics and in ratings of the donation experience. A higher proportion of those unlikely to return were first-time donors, minority-group donors, and donors with less education. The highest projected loss among “safe” donors was seen for those who gave a fair to poor assessment of their treatment by blood center staff or of their physical well-being during or after donating. CONCLUSION: These data suggest that efforts to improve donors' perceptions of their donation experience, as well as attention to the physical effects of blood donation, may aid in the retention of both repeat and first-time donors.     

Rupture of the posterior tibial tendon: CT and surgical findings

Computed tomography (CT) was performed in 42 patients with 49 clinically suspected tears of the posterior tibial tendon. Twenty-eight of the 49 suspected tears were subsequently surgically explored and repaired. Three patterns of tendon abnormalities were recognized on CT scans: type I-intact, hypertrophied, heterogeneous tendon; type II-attenuated tendon; and type III-absence of a portion of a tendon. Types I and II correlated with partial rupture seen during surgery, and type III correlated with complete rupture of the tendon. CT findings were accurate in 96% of the patients who underwent surgery. In four cases (14%), tendon rupture was seen on CT scans, but the extent of the injury was underestimated and the rupture was misclassified. Reactive periostitis of the distal tibia was seen in 71% of diseased tendons and may represent an important factor in the diagnosis of tendon rupture.     

Nonimmune hydrops caused by massive fetomaternal hemorrhage and treated by intravascular transfusion.

Fetal hydrops at 26 weeks' gestation was diagnosed following a massive fetomaternal hemorrhage. Fetal intravascular transfusion was performed, and the hydrops completely resolved within 72 hours. The fetus required one more transfusion at 27 weeks' gestation. A subsequent percutaneous umbilical blood sampling at 30 weeks' gestation demonstrated a normal fetal hematocrit. A vaginal delivery at term resulted in a normal newborn. Massive fetomaternal hemorrhage is a well-known cause of nonimmune hydrops and may occur spontaneously in an otherwise normal pregnancy. Confirmation by percutaneous umbilical blood sampling and treatment by intravascular transfusion is recommended when massive fetomaternal hemorrhage causes hydrops in preterm gestations.     

Prevalence and intensity of Cephalobium microbivorum (Nematoda: Diplogasterida) infection in three species of Gryllus field crickets

Here we report on the results of a survey for nematode parasites in three species of field cricket, Gryllus integer, Gryllus lineaticeps, and an undescribed Gryllus species. The nematode, Cephalobium microbivorum, was recovered from the intestine of the crickets. To our knowledge, this paper is just one of two to report on the biology of C. microbivorum. This nematode was first described from the cricket, Gryllus assimilis. It has not been documented in any other Gryllus species to date. G. integer were collected from two locations: Aguila, Arizona and Davis, California. G. lineaticeps were collected from Davis, CA and an undescribed species of Gryllus cricket was collected from Aguila, AZ. Results of the survey revealed the presence of nematodes in all three species of Gryllus, at all collection sites. The intensity of infection ranged from 1 to 113 nematodes.
