A systematic review of the effectiveness of ofloxaxin otic solution for the treatment of suppurative otitis media

The objectives of the study were to determine the effectiveness and incidence of adverse events of ofloxacin otic solution for suppurative otitis media compared with other treatments. All randomized controlled trials and nonrandomized comparative clinical trials published from 1966 to 2000 using ofloxacin otic solution as one of the interventions were reviewed and data were extracted and analyzed. Eleven clinical trials (9 randomized and 2 nonrandomized) enrolling 1,484 adults and children were finally included in the analysis. Five studies employed clear concealment procedure in the allocation of treatment whereas evaluation of outcome was at least single-blinded in 6 trials. The probability of overall cure rate was higher with 0.3% ofloxacin otic solution than with other topical or systemic antibiotics in 9 of the studies analyzed (OR = 2.67; 95% CI = 2.04, 3.50). Resolution of secondary outcome parameters evaluated at least 1 week after treatment was higher with 0.3% ofloxacin otic solution: resolution of otalgia (4 trials; OR = 2.41; 95% CI = 1.2, 4.82); resolution of otorrhea (11 trials; OR = 2.78; 95% CI = 2.12, 3.65), and bacterial eradication rate (6 trials; OR = 3.86; 95% CI = 2.54, 5.87). A subgroup analysis of 4 studies comparing ofloxacin otic solution with antibiotic- and steroid-containing otic solution showed a higher cure rate for ofloxacin otic solution (OR = 2.73; 95% CI = 1.52, 4.90). Another subgroup analysis on 3 studies comparing ofloxacin otic solution with oral systemic antibiotics showed higher resolution of otorrhea with ofloxacin otic solution (OR = 2.78; 95% CI = 2.12, 3.65). Of 4 studies with data on adverse events, the probability of adverse events was lower with ofloxacin otic solution than with other topical antibiotics (OR = 0.28; 95% CI = 0.19, 0.42). Subgroup analysis showed that 0.3% ofloxacin otic solution showed better results in terms of overall cure rate, resolution of otorrhea, otalgia, bacterial eradication rate and incidence of adverse events. Whether due to chronic suppurative otitis media (CSOM) or draining tympanostomy tube, the overall cure rate (CSOM OR = 4.86; with tympanostomy tube OR = 2.13) and resolution of otorrhea (CSOM OR = 4.42; with tympanostomy tube OR = 1.66) were likewise in favor of 0.3% ofloxacin otic solution. The studies included in this meta-analysis showed generally homogenous results in all clinical and laboratory outcomes analyzed, except for the evaluation of adverse events. The authors conclude that 0.3% ofloxacin otic solution is better than other otic antibiotic drops and other oral antibiotics in terms of overall cure rate and resolution of secondary outcome parameters. Estimates on the beneficial effects of ofloxacin otic solution are limited to the period of study included in this review.     

Knowledge use among occupational therapists for infant feeding assessments

BACKGROUND: Canadian occupational therapists practice in a variety of clinical settings and use different assessment approaches. To understand best practice, this study explored therapists' knowledge use for infant feeding assessments. This was chosen as one specific area of practice to study knowledge use. PURPOSE: The purpose of this qualtitative study was to investigate what therapists assess and what procedures they use to carry out their assessments. METHOD: Semi-structured interviews were conducted with 13 therapists with experience evaluating infant feeding. A constant comparative method of data analysis was used to identify common themes. RESULTS: Three themes emerged: the value of medical information, the importance of doing by observing and the need for an adaptive trial and error approach. PRACTICE IMPLICATIONS: These findings suggest therapists' experiential knowledge shape their best practice. This study informs us about the everyday knowledge used by therapists working with infants on feeding issues and helps us to understand why assessment practices may vary amongst therapists and across clinical settings.     

Early decentration of plate-haptic silicone intraocular lenses

We report 4 eyes of a consecutive series of 1299 that developed early decentration of a 10.5 mm diameter plate-haptic silicone intraocular lens (IOL) after uneventful phacoemulsification. All eyes had an intact continuous curvilinear capsulorhexis (CCC) with the IOL placed in the capsular bag. After an initial period of good vision, patients noted the onset of glare or monocular diplopia between 1 and 5 weeks after surgery. On examination, there was no significant anterior capsule contraction; however, the edge of the IOL optic was visible in the undilated pupil. There was adhesion between the anterior and posterior capsules at the margin of the CCC that maintained the IOL decentration. Decentration recurred in 1 eye after the IOL was rotated 90 degrees and recentered. Symptoms resolved in 3 eyes after the IOL was removed and replaced with a rigid IOL with a larger diameter optic.     

Safety and efficacy of peribulbar block as adjunct to general anaesthesia for paediatric ophthalmic surgery

METHODS: Fifty children (age 5-14 years, ASA I-II) undergoing elective ophthalmic surgery were chosen for the study. Of these, 25 received intravenous pethidine (control group) and 25 received a peribulbar block (block group) for perioperative analgesia, and were monitored intraoperatively and postoperatively by an investigator blinded to the analgesic technique. RESULTS: Intraoperative values of haemodynamic variables were significantly higher in the control group (P < 0.01). Requirement for intraoperative rescue analgesic and postoperative analgesia was higher in the control group (P < 0.05 and P < 0.001, respectively). Children in the block group had lower postoperative pain scores at all times. Incidence of oculocardiac reflex was significantly higher (P < 0.001) in the control group. Seventy-six percent of children in the control group had postoperative nausea and vomiting compared to 20% children in the block group (P < 0.001). CONCLUSION: There were no complications related to the block. Peribulbar block appears to be a safe and useful analgesic technique for paediatric ophthalmic surgery.     

Blunt trauma to scrotum in men with spinal cord injury after they had completed rehabilitation in a spinal unit

STUDY DESIGN: A report of three men with spinal cord injury (SCI) who sustained blunt trauma to scrotum after they had completed rehabilitation in the spinal unit. OBJECTIVES: To raise awareness amongst health professionals regarding: (1) mechanism of scrotal trauma in men with SCI (2) need for prompt assessment of scrotal injury (3) measures to be taken by men with SCI and their carers to prevent injury to the scrotum. SETTING: Regional Spinal Injuries Centre, Southport, England. CASE REPORTS: (1) A 31-year-old with C-6 tetraplegia sustained traumatic haematocele as he squashed his right testis while he jumped on to a toilet seat in a hurry for bowel movement. (2) A 28-year-old male with T-7 paraplegia sat on his left testis while transferring on to a car seat. (3) A boxer dog jumped on to the scrotum of a 40-year-old male with T-8 paraplegia, while he was lying on his bed. CONCLUSIONS: Men with SCI are at high risk of sustaining trauma to scrotum during transfers. The scrotum may be squashed by the weight of the body during transfers, or the scrotum may be trapped between the thighs or under the torso. Men with SCI or their carers should check after each transfer that the scrotum is not trapped between the thighs or under the torso. The health professionals should encourage men with SCI to update their transfer skills at regular intervals in order to prevent trauma to the scrotum during transfers. Blunt trauma to scrotum requires prompt evaluation by ultrasonography so that appropriate treatment can be instituted without delay.     

Dexamethasone is a cost-effective alternative to ondansetron in preventing PONV after paediatric strabismus repair

This study evaluated the antiemetic efficacy, cost-effectivenessand clinical utility of prophylactic ondansetron and dexamethasonecompared with placebo in the prevention of postoperative nauseaand vomiting (PONV) in 135 children (2–15 yr, ASA I–II)undergoing strabismus repair. After induction with halothaneand nitrous oxide in oxygen or i.v. thiopental, the childrenreceived i.v. dexamethasone 1 mg kg^–1 to a maximumof 25 mg, ondansetron 100 µg kg^–1to a maximum of 4 mg or placebo (n=45). Episodes of PONVwere recorded for the first 24 h after the operation. Trueoutcome measures (parental satisfaction score, duration of stayin the postanaesthesia care unit and fast tracking time), therapeuticoutcome measures (number needed to prevent (NNTP) PONV) andthe cost to benefit a child with each drug were analysed. Theincidence and severity of PONV in the first 24 h were significantlyless in the dexamethasone and ondansetron groups than in theplacebo group (P<0.05). The incidence (P=0.04) and severity(P=0.03) of PONV at the 6–24 h epoch were significantlyless in the dexamethasone group than in the ondansetron group.Recovery time (P=0.07), fast tracking time (P=0.6), parentalsatisfaction scores (P=0.08) and NNTP PONV were comparable (NNTP=2)in both the ondansetron and the dexamethasone group. The costto benefit a child with dexamethasone was approximately 22 timesless than that of ondansetron. Br J Anaesth 2001; 86: 84–9
