Assessment of an abbreviated odorant identification task for children: a rapid screening device for schools and clinics

To validate the level of olfactory performance of children, we tested 825 volunteers, aged 4–17 years, with an abbreviated form of our pediatric odorant identification task. The test consisted of sniffing and identifying five odorants (baby powder, bubble gum, candy cane, licorice and peach). Mean olfactory scores increased as a function of age, reaching a plateau of about 94–95% correct at 8 years of age. In general, girls out–performed boys. Physicians require a test instrument such as the one we have devised to allow them to diagnose olfactory dysfunction in children. The present task is particularly applicable in screening large numbers of children in clinics or schools because it can be administered easily and rapidly. Adult subjects with olfactory dysfunction also performed poorly on this odorant identification task designed for children. Therefore, we expect that our odorant identification task will also detect children with severe olfactory dysfunction.     

Hypertension secondary to progressive vascular neurofibromatosis

A 4 year old girl with neurofibromatosis type 1 (NF1) was referred for hypertension. An aortogram showed narrowing of the left main renal artery. An angiogram three and a half years later showed coarctation of the abdominal aorta. She underwent aortoplasty but the stenosis recurred. Vascular involvement in NF1 may be progressive and requires long term follow up.     

The presence or absence of an impalpable testis can be predicted from clinical observations alone

OBJECTIVE: To evaluate, in a prospective study, the accuracy of predicting the presence or absence of unilateral or bilateral impalpable testes from a clinical examination, particularly whether the contralateral descended testis (CDT) is hypertrophied. PATIENTS AND METHODS: Whether the ipsilateral scrotal appendages were palpable, and the size of the CDT, were determined before surgery in a series of patients, and compared with age-matched controls. Between 1992 and 2000, 100 impalpable testes in 86 consecutive patients (mean age at orchidopexy 45 months, range 6-223; 66% <36 months) were evaluated and treated. In addition to the presence or absence of palpable ipsilateral scrotal appendages, the size of the CDT, when present, and the intraoperative findings were recorded. Logistic regression analysis was used to model the probability of the presence or absence of the testis, as determined by the preoperative clinical findings alone. RESULTS: Of the 86 testes that were located at surgery, 50 (58%) were intracanalicular, 28 (32%) intra-abdominal and the remainder (10%) were in the superficial inguinal pouch. Of 13 patients with the 'vanishing testis syndrome', the atrophic testicle was intracanalicular in nine, in the upper scrotum in three and intra-abdominal in only one. All viable testes were successfully relocated in the scrotum, with one atrophic after surgery. The positive predictive value (PPV, with 95% confidence interval) of a testis being present when the ipsilateral appendages were palpable and the CDT was not hypertrophied was 0.93 (0.83-0.97). Conversely, the PPV of the impalpable testis being absent when the appendages were impalpable and the CDT was hypertrophied was 0.95 (0.64-0.99). CONCLUSION: When evaluating and surgically treating impalpable testes, the presence of palpable ipsilateral scrotal appendages and a CDT with no hypertrophy is associated with a 93% likelihood of discovering a testis that can be successfully relocated to the scrotum. Conversely, when the ipsilateral scrotal appendages cannot be palpated and the CDT is hypertrophied, there is a 96% probability that the impalpable testis is absent (vanishing testis syndrome). This readily available information may be valuable in preoperative counselling and planning.     

Clinical psychology Ph.D. program rankings: evaluating eminence on faculty publications and citations

Program rankings and their visibility have taken on greater and greater significance. Rarely is the accuracy of these rankings, which are typically based on a small subset of university faculty impressions, questioned. This paper presents a more comprehensive survey method based on quantifiable measures of faculty publications and citations. The most frequently published core clinical faculty across 157 APA-approved clinical programs are listed. The implications of these data are discussed.     

Growth monitoring: testing the new guidelines

OBJECTIVE: To assess the impact of recent guidelines from the UK joint working party of child health surveillance recommending that all children be measured at age 5 and again between 7 and 9 years of age to determine how many normal school age children are likely to be referred for specialist assessment. METHODS: The longitudinal data of 486 children measured by school nurses in a community setting were examined and compared with measurements made in a research setting by a single, skilled observer. MAIN OUTCOME MEASURES: Number of children identified as having abnormal stature (< 0.4th or > 99.6th centile) and abnormal growth rate height standard deviation score (HSDS) change > 0.67). RESULTS: The community survey identified seven (1.4%) children as having abnormal stature (four short, three tall), 11 (2.3%) were identified as "slow growing", and nine (1.9%) increased their HSDS by more than 0.67. These results were comparable to data collected in ideal research conditions. CONCLUSIONS: Following the recommendations would not result in an excess number of inappropriate referrals. However, this study highlights several unresolved issues such as interobserver variability and time interval between measurements. A large scale prospective study should be considered to establish realistic and cost-effective criteria before implementation of a national screening programme.     

COMPARATIVE EVALUATION OF NO-SCALPEL VASECTOMY AND STANDARD INCISIONAL VASECTOMY

No-scalpel vasectomy employs a refined method of dissection and delivery of the vas deferens. We compared no-scalpel vasectomy with standard incisional vasectomy in 176 patients over a 33 month period. The haemorrhage rate was 1.08 per cent for no-scalpel vasectomy compared with 11.9 per cent for standard vasectomy (p < 0.005). The infection rate was 3.26 per cent for no-scalpel vasectomy as against 14.28 per cent for standard vasectomy (p < 0.01). There was a 37.5 per cent reduction in operating time and a substantial reduction in pain during and after the procedure when no-scalpel vasectomy was performed and also there was no failure of vasectomy. No-scalpel vasectomy is a satisfactory alternative to standard vasectomy with fewer complications and increased patient acceptability.KEYWORDS: Male sterilization, Vasectomy     

Sex differences in outcomes of sinus surgery

PURPOSE: Sex has been demonstrated to affect outcome in many diseases. Our current aim is to investigate the relationship between sex and outcomes of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). METHODS: Forty-four males and 73 females undergoing ESS for CRS with a mean follow-up of 1.4 years were evaluated prospectively. Computed tomography (CT), endoscopy, and quality of life (QOL) assessment was performed. Univariate analyses were performed to evaluate whether sex was predictive of outcome. Multiple logistic regression analysis was performed to evaluate sex association with patient factors predictive of outcome. RESULTS: Although no sex differences in CT and endoscopy were observed (CT, P=.107 and endoscopy, P>.1), females consistently scored worse than males on disease-specific QOL pre- and postoperatively. Importantly, there was no effect of sex on improvement/change scores for the QOL instruments. PREDICTIVE MODELS AND MULTIPLE LOGISTIC REGRESSION ANALYSIS: Sex was not found to be predictive of QOL or endoscopic outcome. Female sex was, however, associated with acetylsalicylic acid (ASA) intolerance and depression, both factors that have been associated with poorer outcome. CONCLUSION: Despite similarities in objective disease measures, females report significantly worse QOL scores pre- and postoperatively. Postoperative improvement did not differ by sex, nor was sex predictive of postoperative outcome. Sex differences in QOL reflect sex differences in ASA intolerance and depression, both more prevalent in females.
