Abstract
BACKGROUND AND AIMS Defecation Disorders (DD) are a frequent cause of refractory chronic constipation. DD diagnosis requires anorectal physiology testing. Our aim was to evaluate the accuracy and Odds Ratio (OR) of a straining question (SQ) and a digital rectal examination (DRE) augmented by abdomen palpation on predicting a DD diagnosis in refractory CC patients. METHODS Two hundred and thirty-eight constipated patients were enrolled. Patients underwent SQ, augmented DRE and balloon evacuation test before entering the study and after a 30-day fiber/laxative trial. All patients underwent anorectal manometry. OR and accuracy were calculated for SQ and augmented DRE for both dyssynergic defecation and inadequate propulsion. RESULTS "Anal Muscles" response was associated to both dyssynergic defecation and inadequate propulsion, with an OR of 13.6 and 5.85 and an accuracy of 78.5% and 66.4%, respectively. "Failed anal relaxation" on augmented DRE was associated with dyssynergic defecation, with an OR of 21.4 and an accuracy of 73.1%. "Failed abdominal contraction" on augmented DRE was associated with inadequate propulsion with an OR >100 and an accuracy of 97.1%. CONCLUSIONS Our data support screening constipated patients for DD by SQ and augmented DRE to improve management and appropriateness of referral to biofeedback.

Abstract
Both computed tomography enterography (CTE) and video capsule endoscopy (VCE) are used in identifying small intestinal pathology in patients with suspected small bowel bleeding (SSBB) following normal upper gastrointestinal endoscopy and colonoscopy. Evidence of the comparative accuracy of these two modalities is crucial for clinical and healthcare decision-making. Comprehensive electronic searches were performed for studies on CTE and/or VCE with reference standard(s). Study selection, data extraction and quality assessment were completed by two authors independently. The QUADAS-2 and QUADAS-C tools were used to assess risk of bias, and applicability. Meta-analysis was performed using a bivariate model to obtain summary estimates of sensitivity, specificity, positive and negative likelihood ratios. Twenty-five studies involving 1986 patients with SSBB were included. Four of these were head-to-head comparison of CTE and VCE. Overall, VCE provided significantly higher sensitivity of 0.74 (95% CI: 0.61-0.83) versus 0.47 (95% CI: 0.32-0.62) for CTE, while CTE showed significantly higher specificity of 0.94 (95% CI: 0.64-0.99) versus 0.53 (95% CI: .36-0.69) for VCE. The positive likelihood ratio of CTE was 7.36 (95% CI: 0.97-56.01) versus 1.58 (95% CI: 1.15-2.15) for VCE and the negative likelihood ratio was 0.49 (95% CI: 0.33-0.72) for VCE versus 0.56 (0.40-0.79) for CTE. A secondary analysis of only head-to-head comparative studies gave results that were similar to the main analysis. Certainty of evidence was moderate. Neither VCE nor CTE is a perfect test for identifying etiology of SSBB in small intestine. VCE was more sensitive while CTE was more specific. Clinicians should choose the appropriate modality depending on whether better sensitivity or specificity is required in each clinical scenario.

Abstract
OBJECTIVE Acute dizziness/vertigo is usually due to benign inner-ear causes but is occasionally due to dangerous neurologic ones, particularly stroke. Because symptoms and signs overlap, misdiagnosis is frequent and overuse of neuroimaging is common. We assessed the accuracy of bedside findings to differentiate peripheral vestibular from central neurologic causes. METHODS We performed a systematic search (MEDLINE and Embase) to identify studies reporting on diagnostic accuracy of physical examination in adults with acute, prolonged dizziness/vertigo ("acute vestibular syndrome" [AVS]). Diagnostic test properties were calculated for findings. Results were stratified by examiner type and stroke location. RESULTS We identified 6,089 citations and included 14 articles representing 10 study cohorts (n = 800). The Head Impulse, Nystagmus, Test of Skew (HINTS) eye movement battery had high sensitivity 95.3% (95% confidence interval [CI] = 92.5-98.1) and specificity 92.6% (95% CI = 88.6-96.5). Sensitivity was similar by examiner type (subspecialists 94.3% [95% CI = 88.2-100.0] vs non-subspecialists 95.0% [95% CI = 91.2-98.9], p = 0.55), but specificity was higher among subspecialists (97.6% [95% CI = 94.9-100.0] vs 89.1% [95% CI = 83.0-95.2], p = 0.007). HINTS sensitivity was lower in anterior cerebellar artery (AICA) than posterior inferior cerebellar artery (PICA) strokes (84.0% [95% CI = 65.3-93.6] vs 97.7% [95% CI = 93.3-99.2], p = 0.014) but was "rescued" by the addition of bedside hearing tests (HINTS+). Severe (grade 3) gait/truncal instability had high specificity 99.2% (95% CI = 97.8-100.0) but low sensitivity 35.8% (95% CI = 5.2-66.5). Early magnetic resonance imaging (MRI)-diffusion-weighted imaging (DWI; within 24-48 hours) was falsely negative in 15% of strokes (sensitivity 85.1% [95% CI = 79.2-91.0]). INTERPRETATION In AVS, HINTS examination by appropriately trained clinicians can differentiate peripheral from central causes and has higher diagnostic accuracy for stroke than MRI-DWI in the first 24-48 hours. These techniques should be disseminated to all clinicians evaluating dizziness/vertigo. ANN NEUROL 2023;94:295-308.

Abstract
OBJECTIVE To evaluate the utility of diagnostic studies in identifying treatable etiologies of trigeminal neuropathy (TNP). PATIENTS AND METHODS We performed a review of consecutive patients with nontraumatic, noniatrogenic TNP seen at Mayo Clinic between January 1, 2000, and August 31, 2019. Patients were excluded if they had trigeminal neuralgia without neuropathy or if their diagnostic work-up had been completed elsewhere. Data were analyzed to determine which diagnostic studies were most useful in identifying treatable etiologies. RESULTS In total, 439 patients were included. The mean ± SD age was 56.3±13.6 years and 285 (64.9%) were female. Among the 180 cases in which an etiology was identified (41.0%), neoplasms were causative in 76 (42.2%), while specific connective tissue diseases were implicated in 71 (39.4%). Bilateral TNP (n=83) was associated with the presence of underlying connective tissue disease (P<.01). Identification of etiology was made by magnetic resonance imaging in 88 cases (48.8%), by abnormal connective tissue disease cascades combined with rheumatology consultation in 42 (23.3%), by a previously known connective tissue disorder in 30 (16.7%), and by abnormal connective tissue disease cascades alone in 8 (4.4%). Among the 439 study patients, electromyography was performed in 211 (48.1%) and lumbar puncture in 139 (31.7%), but their diagnostic utility was low. CONCLUSION Underlying causes of nontraumatic, noniatrogenic TNP can be identified in approximately 40% of cases. Bilateral TNP is strongly associated with underlying connective tissue disease. Careful history taking, dedicated magnetic resonance imaging, and connective tissue panels have the greatest diagnostic utility. Electromyography and cerebrospinal fluid analysis are unlikely to elucidate treatable etiologies of TNP.

Abstract
BACKGROUND Chronic cough is the main reason why parents seek medical treatment for their children. This study aimed to evaluate changes in airway function and inflammation levels and associated values in diagnosing and treating chronic cough. MATERIAL AND METHODS This study involved 118 children with chronic cough, including 45 cough-variant asthma (CVA) patients, 53 upper-airway cough syndrome (UACS) patients, and 20 post-infection cough (PIC) patients. Chronic cough was diagnosed as described by guidelines of the American College of Chest Physicians for evaluating chronic cough. Pulmonary ventilation function and airway hyperresponsiveness (AHR) were evaluated. Fractional exhaled nitric oxide (FeNO) levels and eosinophilic airway inflammation were measured. Eosinophil (EOS) count in sputum was also examined. CVA patients were treated with inhaled glucocorticoids, which have anti-inflammatory effects. RESULTS FeNO and sputum EOS levels were higher in CVA patients compared with UACS and PIC patients (P<0.05). CVA patients demonstrated significantly higher small airway indexes, including 25% forced expiratory flow (FEF), 50% FEF, and 75% FEF, compared with UACS and PIC patients (P<0.05). FeNO level was positively correlated with EOS in sputum (r=0.468, P=0.0001) and cough symptom scores (r=0.402, P<0.05). FeNO, EOS, and cough symptoms were significantly improved in CVA patients after glucocorticoid treatment. AHR was improved in all chronic cough patients after treatment. Cough-relief CVA patients demonstrated significantly higher FeNO levels compared with those without cough relief (P<0.05). CONCLUSIONS FeNO integrating pulmonary function and AHR examination can improve etiologic diagnosis and treatment for chronic cough in children.

Abstract
OBJECTIVE Saline infusion test (SIT) and captopril challenge test (CCT) are standard confirmatory procedures routinely used in the diagnostic work-up of primary aldosteronism (PA). However, side effects and complications during testing have not been systematically studied. DESIGN We performed a cohort study with patients undergoing SIT and/or CCT in two centers from 2016 until 2018. METHODS We studied 272 study participants with suspected PA enrolled at two outpatient centers in Germany. We assessed the frequency and severity of side effects during adjustment of blood pressure medication and during SIT and CCT. RESULTS During the adjustment phase prior confirmatory testing, side effects including palpitations, headaches, edema and hypertensive episodes occurred in 18.4% of study participants. Side effects were associated with higher defined daily doses (DDD) (r = 0.25, P < 0.005), number of antihypertensive drugs (r = 0.285, P < 0.005) and higher blood pressure (r = 0.145, P = 0.019). During SIT, 17.5% of study participants had side effects, associated with higher blood pressure (systolic: r = 0.541, P < 0.0005; diastolic: r = 0.426, P < 0.0005) and DDDs (r = 0.727, P < 0.0005). During CCT, only 1.5% of study participants developed side effects. CONCLUSIONS In contrast to the high rate of side effects during SIT, CCT appears to be the safer test with a very low event rate. This makes CCT especially suitable for severely hypertensive patients.

Abstract
BACKGROUND The enteric string test can be used to obtain a specimen for microbiological confirmation of tuberculosis in children, but it is not widely used for this. The aim of this analysis to evaluate this approach in children with tuberculosis symptoms. METHODS We conducted a cross-sectional study to assess children's ability to complete the test (feasibility), and self-reported pain (tolerability). We examined caregivers' and children's willingness to repeat the procedure (acceptability) and described the diagnostic yield of cultures for diagnostic tools. We stratified estimates by age and compared metrics to those derived for gastric aspirate (GA). RESULTS Among 148 children who attempted the string test, 34% successfully swallowed the capsule. Feasibility was higher among children aged 11-14 than in children 4-10 years (83% vs 22% respectively, p < 0.0001). The string test was better tolerated than GA in both age groups; however, guardians and older children reported higher rates of willingness to repeat GA than the string test (86% vs. 58% in children; 100% vs. 83% in guardians). In 9 children with a positive sputum culture, 6 had a positive string culture. The one children with a positive gastric aspirate culture also had a positive string culture. CONCLUSION Although the string test was generally tolerable and accepted by children and caregivers; feasibility in young children was low. Reducing the capsule size may improve test success rates in younger children.

Abstract
PURPOSE The diagnosis of adult GH deficiency (AGHD) is challenging and often requires confirmation with a GH stimulation test (GHST). The insulin tolerance test (ITT) is considered the reference standard GHST but is labor intensive, can cause severe hypoglycemia, and is contraindicated for certain patients. Macimorelin, an orally active GH secretagogue, could be used to diagnose AGHD by measuring stimulated GH levels after an oral dose. MATERIALS AND METHODS The present multicenter, open-label, randomized, two-way crossover trial was designed to validate the efficacy and safety of single-dose oral macimorelin for AGHD diagnosis compared with the ITT. Subjects with high (n = 38), intermediate (n = 37), and low (n = 39) likelihood for AGHD and healthy, matched controls (n = 25) were included in the efficacy analysis. RESULTS After the first test, 99% of macimorelin tests and 82% of ITTs were evaluable. Using GH cutoff levels of 2.8 ng/mL for macimorelin and 5.1 ng/mL for ITTs, the negative agreement was 95.38% (95% CI, 87% to 99%), the positive agreement was 74.32% (95% CI, 63% to 84%), sensitivity was 87%, and specificity was 96%. On retesting, the reproducibility was 97% for macimorelin (n = 33). In post hoc analyses, a GH cutoff of 5.1 ng/mL for both tests resulted in 94% (95% CI, 85% to 98%) negative agreement, 82% (95% CI, 72% to 90%) positive agreement, 92% sensitivity, and 96% specificity. No serious adverse events were reported for macimorelin. CONCLUSIONS Oral macimorelin is a simple, well-tolerated, reproducible, and safe diagnostic test for AGHD with accuracy comparable to that of the ITT. A GH cutoff of 5.1 ng/mL for the macimorelin test provides an excellent balance between sensitivity and specificity.

Abstract
Recent data suggest that knowledge of radiation exposures among physicians is inadequate. This study, therefore, aimed to evaluate their knowledge of the radiation doses their patients received and awareness of associated biological risks of radiation exposure. A questionnaire in multiple-choice format consisted of four sections with a total of 10 questions based on the literature review. A total of 136 questionnaires were returned from 69 general practitioners and 67 physicians in various specialties from 10 different hospitals in the capital city of Tehran, Iran. Fifty-four percent of general practitioners and twenty-five percent of specialties declared that they are not aware of biological risks of radiation exposure. Fifty-six percent of physicians did not know the correct definition of absorbed dose. Only 33% of physicians knew the dose exposure of a chest X-ray and only 31% knew the approximate doses of various procedures relative to a chest X-ray. Forty-seven percent of physicians incorrectly distinguished the stochastic effects of radiation from the deterministic effects, and thirty-eight of physicians did not know the organs of the body that are most sensitive to ionizing radiation. Only 23.5% of physicians were aware of the one in 2000 risk of induction of fatal carcinoma from computed tomography of the abdomen. Seventy-nine percent of physicians incorrectly underestimated the contribution of nuclear and radiological tests in exposure of an average person. The mean score of the specialties trended toward being more accurate than general practitioners (4.18 ± 1.28 vs. 3.89 ± 1.46, respectively, from a potential accurate total score of 9), but these differences were not statistically significant. Among specialists, orthopedics had the highest scores. The present study demonstrated the limited knowledge of radiation exposures among general practitioners and specialists and a need to improve their knowledge by means of targeted training and re-education.

Abstract
UNLABELLED The 2011 IOM report stated that pain management in children is often lacking especially during routine medical procedures. The purpose of this review is to bring a developmental lens to the challenges in assessment and non-pharmacologic treatment of pain in young children. METHOD A synthesis of the findings from an electronic search of PubMed and the university library using the keywords pain, assessment, treatment, alternative, complementary, integrative, infant, toddler, preschool, young, pediatric, and child was completed. A targeted search identified additional sources for best evidence. RESULTS Assessment of developmental cues is essential. For example, crying, facial expression, and body posture are behaviors in infancy that indicate pain: however in toddlers these same behaviors are not necessarily indicative of pain. Preschoolers need observation scales in combination with self-report while for older children self-report is the gold standard. Pain management in infants includes swaddling and sucking. However for toddlers, preschoolers and older children, increasingly sophisticated distraction techniques such as easily implemented non-pharmacologic pain management strategies include reading stories, watching cartoons, or listening to music. DISCUSSION A developmental approach to assessing and treating pain is critical. Swaddling, picture books, or blowing bubbles are easy and effective when used at the appropriate developmental stage and relieve both physical and emotional pain. Untreated pain in infants and young children may lead to increased pain perception and chronic pain in adolescents and adults. Continued research in the non-pharmacological treatment of pain is an important part of the national agenda.

Abstract
It has been suggested that Pap tests, when used as surrogate markers for routine pelvic examinations in asymptomatic women, may be associated with an increased short-term risk of urinary tract infections (UTIs). This retrospective cohort study used Defense Medical Surveillance System (DMSS) data from 2007 through 2013 to compare the incidence of UTIs in active component women before and after receiving a routine screening Pap examination. The pre-Pap (baseline) UTI incidence rate in this cohort was 105.9 per 1,000 person-years (p-yrs) compared to 129.8 per 1,000 p-yrs post-Pap; the rate ratio was 1.23 (95% CI: 1.18-1.27). The adjusted relative risk of UTI post-Pap was 1.14 (95% CI: 1.10-1.18) and the adjusted percentage of UTIs attributable to a Pap test in the post-exposure period was 12.2% (95% CI: 9.1-15.2). Routine Pap tests, when used as a surrogate marker for pelvic examination, may be a modifiable risk factor for UTI in active component U.S. military women.

Abstract
We evaluated the diagnostic yield of open-lung biopsies (OLBs) in a large tertiary cancer center to determine the role of infectious diseases as causes of undiagnosed pulmonary lesions. All consecutive adult patients with either single or multiple pulmonary nodules or masses who underwent a diagnostic OLB over a period of 10 years (1998-2007) were retrospectively identified. Their risk factors for malignancy and clinical and radiological characteristics were reviewed, and their postoperative complications were assessed. We evaluated 155 patients with a median age of 57 years (range, 19-83 years). We identified infectious etiologies in 29 patients (19 %). The most common diagnosis in this group was histoplasmosis (12 [41 %]), followed by nontuberculous mycobacterial infection (7 [24 %]) and aspergillosis (4 [14 %]). The majority of the 126 remaining patients had nonmalignant diagnoses, the most prevalent being nonspecific granuloma (26 %), whereas only 17 % had malignant diagnoses. We observed no significant differences among the patients with infectious, malignant, or both noninfectious and nonmalignant final diagnoses regarding their demographic, laboratory, and clinical characteristics. Six percent of the patients had at least one post-OLB complication, and the post-OLB mortality rate was 1 %. OLB is a safe diagnostic procedure which frequently identifies a wide variety of infectious and inflammatory diseases.

Abstract
The work is devoted to an analysis of hospitalized patients to the specialized department of injuries of the chest and abdomen of the Mariinskaja hospital at the period from 1993 through 2010. The diagnosis of injury of the pericardium and heart had 280 patients, during the operative treatment heart injuries were detected in 156 (55.71%) patients. Penetration to the heart chambers was found in 132 (84.61%) of them, with perforating and multiple injuries there were 24 (15.39%) patients. Operations were performed during 20 minutes after admission on 65 (28.9%), and during the following two hours on 160 (71.1%) patients. Expectant management and conservative treatment were used in treatment of 34 patients (12.14%), three patients were admitted in the state of apparent death and died during 15 minutes. The lethality of 41 patients was 26.28%. mainly it was those who were operated at the period from 80 to 100 minutes from the moment of injury. The success of treatment depends on the early hospitalization, correct diagnosis and emergent surgery.

Abstract
BACKGROUND Acute pain is a common experience for hospitalized children. Despite mounting research on treatments for acute procedure-related pain, it remains inadequately treated. OBJECTIVE To critically appraise all systematic reviews on the effectiveness of acute procedure-related pain management in hospitalized children. METHODS Published systematic reviews and meta-analyses on pharmacological and nonpharmacological management of acute procedure-related pain in hospitalized children aged one to 18 years were evaluated. Electronic searches were conducted in the Cochrane Database of Systematic Reviews, Medline, EMBASE, the Cumulative Index to Nursing and Allied Health Literature and PsycINFO. Two reviewers independently selected articles for review and assessed their quality using a validated seven-point quality assessment measure. Any disagreements were resolved by a third reviewer. RESULTS Of 1469 published articles on interventions for acute pain in hospitalized children, eight systematic reviews met the inclusion criteria and were included in the analysis. However, only five of these reviews were of high quality. Critical appraisal of pharmacological pain interventions indicated that amethocaine was superior to EMLA (AstraZeneca Canada Inc) for reducing needle pain. Distraction and hypnosis were nonpharmacological interventions effective for management of acute procedure-related pain in hospitalized children. CONCLUSIONS There is growing evidence of rigorous evaluations of both pharmacological and nonpharmacological strategies for acute procedure-related pain in children; however, the evidence underlying some commonly used strategies is limited. The present review will enable the creation of a future research plan to facilitate clinical decision making and to develop clinical policy for managing acute procedure-related pain in children.

Abstract
The oral glucose tolerance test, which is considered the gold standard for the diagnosis of active acromegaly, should not be performed in the presence of basal hyperglycemia. Moreover, false-positive responses may occur in patients with diabetes mellitus. Galanin has previously been demonstrated to induce paradoxical inhibition of growth hormone (GH) secretion in most patients with active acromegaly. In this study, we assessed GH response to galanin infusion in a series of 17 consecutive patients with active acromegaly, 7 of whom had coexistent type 2 diabetes mellitus and 10 were without either diabetes mellitus or impaired tolerance to glucose. 6 acromegalic patients with diabetes mellitus (85.7%) and 7 without diabetes (70.0%) showed a decrease in serum GH values during galanin infusion (chi2 0.9; p = 0.6). The GH nadir occurred at a comparable time in the two groups of acromegalic patients. Moreover, the two groups showed no significant difference (p = 0.45) in DeltaGH during galanin infusion. Galanin infusion did not induce any significant change in plasma glucose levels in both diabetic and non-diabetic patients with acromegaly. The results of our study provide evidence that the galanin test may be of value for the diagnosis of acromegaly in patients with type 2 diabetes mellitus.

Abstract
OBJECTIVES Adverse events (AEs) are poor patient outcomes, resulting from medical care. We performed this study to quantify the misclassification rate obtained using current AE detection methods and to evaluate the effect of combining physician AE ratings. STUDY DESIGN AND SETTING Three physicians independently rated poor patient outcomes. We used latent class analysis to obtain estimates for AE prevalence and reviewer accuracy. These estimates were used as a base case for four simulations of 10,000 cases rated independently by five reviewers. We assessed the effect of AE prevalence, reviewer accuracy, and the number of agreeing reviewers on the probability that cases were correctly classified as an AE. RESULTS Reviewer sensitivity and specificity for AE classification were 0.86 and 0.94, respectively. When prevalence was 3%, the positive predictive value that an AE occurred when a single reviewer classified the case as such was 31%, whereas when 2/3 reviewers did so it was 51%. The positive predictive values of ratings for AE occurrence increased with AE prevalence, reviewer accuracy, and the number of reviewers. CONCLUSION Current methods of AE detection overestimate the risk of AE. Uncertainty regarding the presence of an AE can be overcome by increasing the number of reviews.

Abstract
OBJECTIVES To determine the tolerability and morbidity rate of multichannel urodynamics (UDS). METHODS A total of 154 consecutive patients were included in the present study; 87 men and 67 women underwent UDS and completed a questionnaire. All patients undergoing UDS were given a two-part questionnaire. The first part, given immediately after UDS, contained four questions regarding pain, embarrassment, and physical burden (assessed with a visual analogue scale on which 0 = not at all, 10 = unbearable), as well as willingness to undergo UDS again. The second part, given within 2 weeks after UDS, contained five questions regarding micturition pain, gross hematuria, dysuria, cloudy urine, and fever episodes after UDS. Urine specimens were also analyzed. RESULTS The mean (+/-SD) degrees of pain, embarrassment, and physical burden were 2.27 +/- 2.53, 2.59 +/- 2.69, and 1.76 +/- 2.43, respectively, and 73.6% of men and 80.6% of women were willing to repeat UDS. The most common complaint after UDS was micturition pain. Two men and 1 woman had fever after UDS; there was no relationship between fever and urinary tract infections. Urinalysis showed that 4.6% of men and 7.5% of women had leukocyturia after the investigation. CONCLUSIONS The complication rates of UDS were relatively low. For most patients, UDS were tolerable and acceptable. Proper informed consent is necessary.

Abstract
We report the observation and analysis of a new adverse event during the insulin tolerance test (ITT) and propose additional safety procedures. An 8-year-old girl with growth hormone insufficiency had a cardiac arrest due to ventricular flutter when she was tested for growth hormone deficiency by the ITT. Severe hypokalaemia (K+ 2.6 mmol/l) was observed after resuscitation. Ergometry ECG revealed catecholaminergic polymorphic ventricular tachycardia, a hereditary arrhythmogenic disease. Consecutive measurements of serum potassium during ITT in 29 short children (21 boys) with growth failure revealed a mean decrease of serum potassium by 1.1 +/- 0.4 mmol/l with the nadir at 30 min after the insulin bolus. Hypokalaemia (serum potassium < 3.5 mmol/l) occurred in all but one child; severe hypokalaemia (serum potassium < 2.9 mmol/l) was measured in every third child. This observation indicates that acute hypokalaemia which is induced by insulin and catecholamine excess occurs frequently in ITT. The case shows that the combination of acute hypokalaemia and the adrenergic counterregulation in ITT is a strong trigger of cardiac arrhythmias, which can become life-threatening if the child has an arrhythmogenic disease. Therefore, we recommend ECG monitoring during ITT to enhance the detection of cardiac arrhythmias. In addition, in the case of a comatose child during ITT the determination of the glucose and potassium level as well as adequate treatment are necessary.

Abstract
AIM To study the availability and quality of adult and paediatric colonoscopy in three National Health Service (NHS) regions. METHOD A prospective four month study of colonoscopies in North East Thames, West Midlands, and East Anglia. PATIENTS Subjects undergoing colonoscopy in 68 endoscopy units. RESULTS A total of 9223 colonoscopies were studied. The mean number of colonoscopies performed over the four month period was 142 in district general hospitals and 213 in teaching hospitals. Intravenous sedation was administered in 94.6% of procedures, but 2.2% and 11.4% of "at risk" patients did not have continuous venous access or did not receive supplemental oxygen, respectively. Caecal intubation was recorded in 76.9% of procedures but the adjusted caecal intubation rate was only 56.9%. Reasons for failing to reach the caecum included patient discomfort (34.7%), looping (29.7%), and poor bowel preparation (19.6%). A normal colonoscopy was reported in 42.1%. The most common diagnosis was polyps (22.5%) followed by diverticular disease (14.9%). Inflammatory bowel disease was recorded in 13.9% and carcinoma in 3.8%. Only half of the patients remembered being told of possible adverse events prior to the procedure. Rectal bleeding requiring admission following colonoscopy was reported in six patients. The overall perforation rate was 1:769 and colonoscopy was considered a possible factor in six deaths occurring within 30 days of the procedure. Only 17.0% of colonoscopists had received supervised training for their first 100 colonoscopies and only 39.3% had attended a training course. CONCLUSION There is serious under provision of colonoscopy service in most NHS hospitals. Endoscopy sedation guidelines are not always adhered to and there is a wide variation in practice between units. Colonoscopy is often incomplete and does not achieve the target 90% caecal intubation rate. Serious complications of colonoscopy were comparable with previous studies. Training in colonoscopy is often inadequate and improved practice should result from better training.

Abstract
In the past decade, our knowledge of pain in newborn infants has advanced considerably. However, infants at significant risk for neurologic impairment (NI) have been systematically excluded from almost all research on pain in neonates. The objectives of this study were to compare: (a). the nature, frequency and prevalence of painful procedures, (b). analgesics and sedatives administered, and (c). the relationship between painful procedures and analgesia for neonates at risk for NI. One hundred and ninety-four infants at high (cohort A, n=67), moderate (cohort B, n=59) and low (cohort C, n=68) risk for NI from two tertiary level Neonatal Intensive Care Unit's in Canada were included in a retrospective cohort study on the first 7 days of life. Data were collected from medical records and analyzed using chi-square, ANOVA and regression approaches. All cohorts had a mean of >10 painful procedures per day during the first 2 days of life. There was an interaction effect between cohort group and day of life (F(5,188)=2.13, P<0.06) with cohort A having significantly more painful procedures on day 1 (F(2,191)=4.79, P<0.009). There was no statistical difference in the number of infants who received continuous infusion (F(2,20)=1.9, P=0.13) or bolus (F(2,20)=1.3, P=0.25) opioids or sedatives (F(2,20)=0.45, P=0.84) by cohort over the 7 day period. There was a statistical difference in bolus opioid administration for days 1 (P<0.05) and 2 (P<0.001) with less than 10% of infants in cohort A receiving bolus opioids compared with approximately 22-33% of infants in cohorts B and C. There was a statistically significant correlation between painful procedures and analgesic use (r=0.29, P<0.001), although significant associations existed for cohorts B and C only. The number of painful procedures and study site primarily accounted for the variance (61% in cohort B and 35% in cohort C) in analgesic use, while in cohort A, only study site contributed to the variance (16%). Neonates at the highest risk for NI had the greatest number of painful procedures and the least amount of opioids administered during the first day of life. There was no relationship between painful procedures and analgesic use in this group. As these infants are vulnerable to pain and its consequences, the rational underlying health professional strategies regarding painful procedures and analgesic use for procedural pain in this population urgently awaits exploration.

Abstract
BACKGROUND Despite an increasing awareness regarding pain management in neonates and the availability of published guidelines for the treatment of procedural pain, preterm neonates experience pain leading to short- and long-term detrimental effects. OBJECTIVE To assess the frequency of use of analgesics in invasive procedures in neonates and the associated pain burden in this population. METHODS For 151 neonates, we prospectively recorded all painful procedures, including the number of attempts required, and analgesic therapy used during the first 14 days of neonatal intensive care unit admission. These data were linked to estimates of the pain of each procedure, obtained from the opinions of experienced clinicians. RESULTS On average, each neonate was subjected to a mean +/- SD of 14 +/- 4 procedures per day. The highest exposure to painful procedures occurred during the first day of admission, and most procedures (63.6%) consisted of suctioning. Many procedures (26 of 31 listed on a questionnaire) were estimated to be painful (pain scores >4 on a 10-point scale). Preemptive analgesic therapy was provided to fewer than 35% of neonates per study day, while 39.7% of the neonates did not receive any analgesic therapy in the neonatal intensive care unit. CONCLUSIONS Clinicians estimated that most neonatal intensive care unit procedures are painful, but only a third of the neonates received appropriate analgesic therapy. Despite the accumulating evidence that neonatal procedural pain is harmful, analgesic treatment for painful procedures is limited. Systematic approaches are required to reduce the occurrence of pain and to improve the analgesic treatment of repetitive pain in neonates.

Abstract
BACKGROUND AND STUDY AIMS In an outpatient gastroenterological practice setting, highly effective diagnostic procedures and patient satisfaction play an important role. Ultrathin endoscopy in unsedated patients has been shown to be more cost-effective and time-efficient in comparison with standard endoscopy. A prospective randomized study was carried out in unsedated patients to compare performance, feasibility, safety, and patient tolerance between ultrathin transnasal (UT), ultrathin oral (UO), and standard (SO) esophagogastroduodenoscopy (EGD). PATIENTS AND METHODS A total of 200 of 600 eligible patients consented to participate in the study, and were randomly assigned to undergo UT, UO, or SO. Patients reported their tolerance of the procedure (anxiety, pain, gagging, and overall satisfaction; Likert scale 1-10), and the endoscopists reported the effectiveness of the procedure (handling, picture quality, and overall performance; Likert scale 1-10). Statistics were calculated using the Kruskal-Wallis test. RESULTS After randomization, 65, 67, and 68 patients were allocated to the UT, UO, and SO groups, respectively. Failure to achieve complete EGD by the intended route occurred in 14 patients (22 %) in the UT group. Compared to the SO group, patients in the UT and UO groups rated anxiety before the procedure as being more intense - median score (10 % quantile estimate; 90 % quantile estimate): UT, 2.0 (1.0; 4.0); UO, 2.0 (1.0; 4.0); SO, 0.0 (0.0; 2.0); p < 0.0001), whereas SO patients experienced a higher level of anxiety during the procedure ( P < 0.0001). Pain during insertion of the endoscope was the least intense in the UO group: UT, 2.0 (1.0; 5.0); UO, 1.0 (1.0; 3.0); SO, 2.0 (1.0; 4.0); P < 0.001). Gagging during insertion was more pronounced in the UO group: UT, 2.0 (1.0; 4.0); UO, 3.0 (1.0; 7.0); SO, 2.0 (1.0; 5.0); P < 0.01). The patients' score for the overall assessment was better in the SO group ( P < 0.0001). The endoscopists' overall assessment for ultrathin EGD was poorer than for standard EGD: UT, 3.0 (2.0; 5.0); UO, 3.0 (2.0; 5.0); SO, 2.0 (1.0; 3.0); P < 0.0001). CONCLUSIONS Ultrathin endoscopy through both the transnasal and oral routes has limited use in routine outpatient practice. Techniques for reducing pain and gagging may improve patient tolerance. Further technical improvements are needed to allow routine implementation.

Abstract
This study investigated preserved memory in 26 pediatric cancer patients (65% boys, 77% Caucasian, mean age = 12.5 years) undergoing midazolam-induced conscious sedation during painful medical procedures to treat hematological or oncological diseases. The sedative midazolam had a significant anterograde amnesic effect on participants' performance on a visual recognition (explicit) memory task but not on a visual perceptual facilitation (implicit) memory task. That implicit memory scores were relatively unaffected while explicit memory scores deteriorated significantly indicates that leaning occurred while participants were sedated, even when participants did not recollect the learning event. These findings, which replicate those of M. R. Polster, R. A. McCarthy, G. O'Sullivan, P. A. Gray, and G. R. Park (1993) in a study of adults, have implications for the development and treatment of conditioned anxiety reactions associated with aversive medical procedures.

Abstract
BACKGROUND Colonoscopy can be difficult in some women who have undergone hysterectomy, which can be associated with a fixed, angulated sigmoid colon caused by postoperative pelvic adhesions. Our goal was to determine whether colonoscopy is easier and more comfortable for women after hysterectomy when performed with a pediatric colonoscope, which is thinner in diameter and more flexible than a standard "adult" colonoscope. METHODS One hundred women with a history of hysterectomy undergoing outpatient colonoscopy were randomized in unblinded fashion to colonoscopy with a standard colonoscope (CF-100L or CF-Q140L, Olympus) or with a pediatric colonoscope (PCF-100, Olympus). All procedures were performed by a faculty endoscopist and timed. After examination, the endoscopist graded procedure difficulty, and patients were given a questionnaire that assessed their experience. RESULTS The cecum was intubated more frequently in the pediatric colonoscope group than in the standard colonoscope group (96.1% vs. 71.4%, p < 0.001). Success increased in the standard colonoscope group to 89.8% when the pediatric colonoscope was used to complete the examination. There were no differences in the two groups in terms of mean total procedure times (21.4 minutes vs. 22.6 minutes), mean doses of meperidine administered (57 mg both groups), mean doses of midazolam administered (1.5 mg vs. 1.7 mg), scales of procedure difficulty as graded by the endoscopists, and comfort scales as graded by patients. For the cases in which the cecum was intubated, the mean time to reach the cecum (11.7 minutes for the pediatric colonoscope group vs. 12.7 minutes for the adult) was similar. CONCLUSIONS The pediatric colonoscope is a reasonable choice for colonoscopy in women who have had a hysterectomy. Alternatively, if the endoscopist elects to start the procedure with a standard colonoscope, it is helpful to have a pediatric colonoscope available for use should a fixed, angulated sigmoid colon be encountered that cannot be easily or safely traversed with the standard colonoscope.

Abstract
OBJECT The routine use of intraoperative angiography as an aid in the surgical treatment of aneurysms is uncommon. The advantages of the ability to visualize residual aneurysm or unintended occlusion of parent vessels intraoperatively must be weighed against the complications associated with repeated angiography and prolonged vascular access. The authors reviewed the results of their routine use of intraoperative angiography to determine its safety and efficacy. METHODS Prospectively gathered data from all aneurysm cases treated surgically between January 1996 and June 2000 were reviewed. A total of 303 operations were performed in 284 patients with aneurysms; 24 patients also underwent postoperative angiography. Findings on intraoperative angiographic studies prompted reexploration and clip readjustment in 37 (11%) of the 337 aneurysms clipped. Angiography revealed parent vessel occlusion in 10 cases (3%), residual aneurysm in 22 cases (6.5%), and both residual lesion and parent vessel occlusion in five cases (1.5%). When compared with subsequent postoperative imaging, false-negative results were found on two intraoperative angiograms (8.3%) and a false-positive result was found on one (4.2%). Postoperative angiograms obtained in both false-negative cases revealed residual anterior communicating artery aneurysms. Both of these aneurysms also subsequently rebled, requiring reoperation. In the group that underwent intraoperative angiography, in 303 operations eight patients (2.6%) suffered complications, of which only one was neurological. CONCLUSIONS In the surgical treatment of intracranial aneurysms, the use of routine intraoperative angiography is safe and helpful in a significant number of cases, although it does not replace careful intraoperative inspection of the surgical field.

Abstract
BACKGROUND Elevation of cardiac troponin I in the serum is a specific marker for myocardial injury. We measured levels of troponin I in the serum in children before and after cardiac catheterization to determine if this procedure was associated with an increase in levels of troponin. METHODS We enrolled patients under 21 years of age undergoing cardiac catheterization at our institution. A baseline sample of serum was drawn at the start of the procedure. Repeat samples were obtained immediately after, and six hours subsequent to the procedure. All samples were analyzed for cardiac troponin I using the Abbott AxSYM microparticle immunoassay system. Levels were considered normal (0-0.4 ng/ml) or elevated (>0.4 ng/ml). Patients were excluded if the baseline level was elevated. RESULTS Levels of cardiac troponin I were elevated in the serum from 11 of 14 (79%) cases immediately after the procedure (p < 0.0001), and in 12 of 14 (86%) six hours later (p < 0.0001). Only 2 patients had recognized complications potentially causing myocardial injury. CONCLUSION Levels of cardiac troponin I increase in the serum in a high proportion of children after cardiac catheterization. These elevations can be observed immediately, and are maintained for at least six hours. Our study suggests that cardiac catheterization, predominantly intervention, is associated with myocardial injury, even in the absence of complications.

Abstract
This article discusses the interpretation of the diagnostic tests in the management of ventilated patients with suspicion of pneumonia. The specific steps for diagnostic evaluation are identified. An accurate interpretation of the significance of the bacterial burden requires previous evaluation of the sample quality, knowledge of administration of new antibiotics within the prior 48 hours, and evaluation of presence of comorbidities. Finally, the article presents a review of the current debate of impact on outcome.

Abstract
OBJECTIVE The aim of this study was to determine whether endoscopic evaluation of patients referred for liver transplant evaluation contributes significantly to patient selection or management. METHODS Esophagogastroduodenoscopy (EGD) was performed in transplant candidates who had not undergone this examination within a previous 6-month period. Colonoscopy (CSP) was performed if the patient was >50 yr of age or had anemia, a history of colonic pathology such as adenomatous polyps, or a history suggesting gastrointestinal tract abnormalities. RESULTS A total of 118 patients were studied. EGD was performed in 74 (63%) patients. Forty-seven patients had esophageal varices identified; in 26, this represented a new diagnosis. Other findings on EGD included portal gastropathy (21 patients), gastric varices (seven patients), peptic ulceration (10 patients), Barrett's esophagus (three patients), and one case each of esophageal and gastric carcinoma. CSP was performed in 56 patients. Findings included adenomatous polyps (24 patients) and one case of colon carcinoma. Overall, gastrointestinal pathology was discovered in 67 (57%) of the patients undergoing endoscopic evaluation as part of our study. Alterations in patient selection or management resulted from 44% of the procedures performed; 42% of the patients were affected by these management changes and 2.5% of patients were removed from further transplant evaluation because of the diagnosis of malignancy. CONCLUSION Endoscopic evaluation of liver transplant candidates often identifies important gastrointestinal pathology and frequently impacts patient selection and management before OLT.

Abstract
BACKGROUND Despite an increased awareness among clinicians regarding pain and pain management for infants undergoing surgery, pain associated with procedures performed outside the operating room may not be adequately managed. PURPOSE To examine the beliefs and self-described behavior of physicians and nurses regarding the management of procedural pain in newborn infants. METHODS A survey was distributed to 467 clinicians (nurses and physicians) working in 11 level II and 4 level III nurseries in a large metropolitan area. Respondents were asked to rate the painfulness of 12 common bedside nursery procedures and how often pharmacologic and nonpharmacologic (comfort) measures are currently used and should be used for those procedures. Demographic data were also collected. RESULTS Surveys were completed by 374 clinicians (80% response rate). Physicians and nurses believe infants feel as much pain as adults and that 9 of the 12 listed procedures are moderately to very painful. Neither pharmacologic nor comfort measures are believed to be used frequently, even for the most painful procedures. Physicians and nurses believe both pharmacologic and comfort measures should be used more frequently, but nurses believe comfort measures should be used more frequently than do physicians. Beliefs about infant pain and procedural pain were related to pain management preferences. Physicians' but not nurses' ratings were associated with significant personal pain. CONCLUSIONS Despite their beliefs that infants experience significant procedure-related pain, clinicians believe pain management for infants remains below optimal levels. Barriers to more consistent and effective pain management need to be identified and surmounted.

Abstract
In the past two decades, the medical model has extended its jurisdiction to cover a new medical entity-the at-risk health status-which is frequently accompanied by what I call a diagnostic invitation and the 'gift' of knowing. In cases, however, where the diagnosis may only reaffirm the risk but can provide no cure, the value of the 'gift' of knowing is questioned. The at-risk health status also can: (1) develop a symbiotic relationship with diagnostic technology, (2) become an organizing principle in individual and social behavior and (3) provide new tasks for clinical medicine. The perceived cost effectiveness of preventive measures, combined with the desire to use high-technology medicine, to achieve newly expanded definitions of health make it likely that the concept of the at-risk health status will be integrated into whatever health care plan is finally enacted for the United States. In light of the possible negative, as well as positive, effects of at-risk health labelling, American society needs to establish standards for the diagnostic invitation as a gift of knowing especially when the line between prevention and overuse is not always clear.

Abstract
Diagnostic tests and investigations are standard tools for today's general practitioner. However, without reliable systems for the management of tests and test results, these valuable assets may become a liability to the GP, with the possibility of unforeseen adverse events arising at several points in the total investigative process. Exploring GPs' reports of such incidents may provide opportunities for improvements in patient care.

Abstract
The utility of mass screening of preoperative patients has never been demonstrated for the majority of tests. Although screening patients to uncover occult disease appears logical, in reality it has resulted in excessive expenditure of our health care dollars with limited benefit. More than $30 billion is spent annually on preoperative examinations, 60% of which are unnecessary. In addition, iatrogenic injury has resulted from the further evaluation and treatment of false-positive results. A selective utilization of routine examinations can accurately supplement the clinician's evaluation, providing the patient with a complete preoperative assessment. The benefits of selective testing must be balanced against the possible omission of warranted examinations, highlighting the need for a more reliable system for test ordering.

Abstract
This paper argues that clinicians are sometimes justified in not testing diagnoses or in not subjecting them to a full battery of tests. In deciding whether to conduct a test, a clinician may consider and weigh several different factors, including her confidence in her initial diagnosis, the specificity and sensitivity of the test, the consequences of making a false diagnosis, the pain, harm, and inconvenience caused by the test, and the costs of the test to the patient and society. This view suggests that diagnoses are fundamentally different from scientific hypotheses in that they are not always subjected to the same evidential standards.

Abstract
Most fetuses in developed countries are exposed in utero to diagnostic ultrasound examination. Many pregnant women express concern about whether the procedure harms the fetus. Since most routine ultrasound examinations are done at weeks 16-22, when the fetal brain is developing rapidly, effects on neuronal migration are possible. We have sought an association between routine ultrasonography in utero and reading and writing skills among children in primary school. At the age of 8 or 9 years, children of women who had taken part in two randomised, controlled trials of routine ultrasonography during pregnancy were followed-up. The women had attended the clinics of 60 general practitioners in central Norway during 1979-81. The analysis of outcome was by intention to treat: 92% of the "screened" group had been exposed to ultrasound screening at weeks 16-22, and 95% of controls had not been so exposed, but there was some overlap. 2428 singletons were eligible for follow-up, and the school performance of 2011 children (83%) was assessed by their teachers on a scale of 1-7; the teachers were unaware of ultrasound exposure status. A subgroup of 603 children underwent specific tests for dyslexia. There were no statistically significant differences between children screened with ultrasound and controls in the teacher-reported school performance (scores for reading, spelling, arithmetic, or overall performance). Results from the dyslexia test sample showed no differences between screened children and controls in reading, spelling, and intelligence scores, or in discrepancy scores between intelligence and reading or spelling. The test results classified 21 of the 309 screened children (7% [95% confidence interval 3-10%]) and 26 of the 294 controls (9% [4-12%]) as dyslexic. The risk of having poor skills in reading and writing was no greater for children whose mothers had been offered routine ultrasonography than for those whose mothers had not been offered the procedure.
