Kinds of Database Review Selected AbstractsDemographic Factors and Their Association with Outcomes in Pediatric Submersion InjuryACADEMIC EMERGENCY MEDICINE, Issue 3 2006Lois K. Lee MD Objectives: To describe the epidemiology and outcomes of serious pediatric submersion injuries and to identify factors associated with an increased risk of death or chronic disability. Methods: A retrospective database review of 1994,2000 Massachusetts death and hospital discharge data characterized demographic factors; International Classification of Diseases, Ninth Revision (ICD-9), Clinical Modification (ICD-9-CM), or ICD-10 injury codes; and outcomes for state residents 0,19 years of age identified with unintentional submersion injuries. The authors performed logistic regression analysis to correlate outcomes with risk and demographic factors. Results: The database included 267 cases of serious submersion injury, defined as those requiring hospitalization or leading to death. Of these 267 patients, 125 (47%) drowned, 118 (44%) were discharged home, 13 (5%) were discharged home with intravenous therapy or with availability of a home health aide, and 11 (4%) were discharged to an intermediate care/chronic care facility. The authors observed a trend of improved outcome in successively younger age groups (p < 0.0001). The multivariable logistic regression analysis showed an increased likelihood of poor outcome for males compared with females (odds ratio [OR]: 2.52; 95% confidence interval [95% CI] = 1.31 to 4.84) and for African Americans compared with whites (OR: 3.47; 95% CI = 1.24 to 9.75), and a decreased likelihood of poor outcome for Hispanics compared with whites (OR: 0.056; 95% CI = 0.013 to 0.24). Conclusions: After serious pediatric submersion injuries, the overall outcome appears largely bimodal, with children primarily discharged home or dying. The observations that better outcomes occurred among younger age groups, females, and Hispanic children, with worse outcomes in African American children, suggest that injury prevention for submersion injuries should consider differences in age, gender, and race/ethnicity. [source] The value of a specialist lipid clinicINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 6 2008S. C. Martin Summary Aims:, To establish the value of the first 3 years of a cardiovascular risk factor clinic in tackling the major risk factors for cardiovascular disease (CVD). Methods:, A database review of all 339 patients referred to the clinic. Results:, Blood pressure levels in the hypertensive patients were significantly reduced and 9% of the smokers managed to quit for 12 months, half of them subsequently relapsing. Ninety-eight oral glucose tolerance tests were performed and 40% were abnormal yielding 10 patients with hitherto unsuspected diabetes and 29 with impaired glucose tolerance. Sixty-four of the 97 referrals of patients in the primary prevention group (no evidence of CVD) were found to have calculated Framingham coronary heart disease risk estimates of < 15% per decade, the lowest being 0.3%. Lipid levels were significantly reduced in both the hypercholesterolaemic (n = 290) and hypertriglyceridaemic (n = 49) patient groups through the use of more potent statins, extensive use of combination therapy and appropriate use of fibrates and omega-3 fish oil supplements. The annual drug cost per patient treated only increased from £310.72 to £398.08, yet there was a 3.5-fold increase in the number of patients achieving the General Medical Services 2 target of a total cholesterol < 5 mmol/l and a 4.5-fold increase in patients achieving the Joint British Societies 2 target of a low-density lipoprotein (LDL) cholesterol < 2 mmol/l. Conclusion:, The need for a specialist clinic was demonstrated by the 66% of primary prevention referrals who did not meet the current NICE treatment threshold. Additionally, the clinic was able to diagnose and treat 39 patients with undiagnosed diabetes mellitus/impaired glucose tolerance and 12 with hypothyroidism. LDL cholesterol was reduced overall by 36% implying a greater than one-third reduction in future cardiovascular events before the improvements in blood pressure control and smoking cessation are included and this was achieved at marginal extra cost to the mean drug bill at referral. [source] Pre-hospital use of ketamine in paediatric traumaACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2009P. P. BREDMOSE Objectives: To describe the use of ketamine in children by a pre-hospital physician-based service. Methods: A five and a half year retrospective database review of all patients aged <16 years who were attended by London's Helicopter Emergency Medical Service and given ketamine. Results: One hundred and sixty-four children met the inclusion criteria. The median age was 10 years (range 0,15 years). One hundred and four (63%) had a Glasgow Coma Scale (GCS) of 15 and 153 (93%) had a GCS>8 before administration of ketamine. Patients received from 2 to 150 mg ketamine IV (mean=1.0 mg/kg) and 112 (68%) received concomitant midazolam (0.5,18 mg, mean=0.1 mg/kg). One hundred and forty-one (86%) received ketamine intravenously and 23 (14%) intramuscularly. Only 12 patients (7%) were trapped. The most common mechanisms of injury in those who received ketamine were road traffic collisions, burns and falls. Conclusion: The safe delivery of adequate analgesia and appropriate sedation is a priority in paediatric pre-hospital care. Ketamine was predominantly used in awake non-trapped patients with blunt trauma for procedural sedation and analgesia. Detailed database searches did not demonstrate loss of airway, oxygen desaturation or clinically significant emergence reactions after ketamine administration. This study failed to demonstrate any major side effects of the drug and reassured us that the safety profile of the drug in this environment is likely to be satisfactory. The use of ketamine in trapped children was rare. [source] Graft rejection occurring in post,liver transplant patients receiving cytotoxic chemotherapy: A case seriesLIVER TRANSPLANTATION, Issue 6 2009Hui-Hui Tan Liver transplant recipients are known to be at increased risk for the development of de novo neoplasms or the recurrence of preexisting malignancies, and this is possibly related to the use of immunosuppressive medication. Little is known about the effects of cytotoxic chemotherapy on graft function after transplantation. A retrospective chart and pathology database review was undertaken to identify post,liver transplant patients developing rejection during chemotherapy. All liver biopsies were reviewed by a hepatopathologist. Three patients were identified. All patients were diagnosed with cancer within 7 years of liver transplantation; two-thirds died soon after the diagnosis of malignancy. Rejection occurred soon after chemotherapy was started. All patients were receiving prednisone and tacrolimus (trough levels: 2.1-4.8 ng/mL). One patient developed plasma cell hepatitis (de novo autoimmune hepatitis). There was no histologic evidence of hepatotoxicity due to the chemotherapeutic agents. Cytotoxic chemotherapy should be used in liver transplant recipients with caution, and immunosuppressant doses should be maintained at therapeutic levels, as patients may be at risk for allograft rejection. Treatment of rejection or plasma cell hepatitis in this setting should be undertaken in a timely and aggressive fashion to prevent chronic ductopenic rejection.

[source] Ileovesicostomy for adults with neurogenic bladders: Complications and potential risk factors for adverse outcomes,,NEUROUROLOGY AND URODYNAMICS, Issue 3 2008Hung-Jui Tan Abstract Aims Risk factors for complications following ileovesicostomy have not been well defined. This study's purpose was to examine outcomes following ileovesicostomy in adults and identify possible risk factors that may contribute to post-operative complications. Methods Retrospective database review identified ileovesicostomy procedures from August 1999 to September 2003. Demographic, pre-operative, and post-operative data were extracted. Statistical analysis determined whether risk factors influenced outcomes of urethral continence, re-operation, and post-operative complications. Factors included age, tobacco use, diabetes, neurogenic bladder etiology, body mass index, pre-operative indwelling catheterization, or simultaneous procedures including pubovaginal sling/urethral closure. Results 50 adults status-post ileovesicostomy were identified. At last follow-up, 36 patients (72%) were continent per urethra. The incidence of complications decreased significantly from 3.38 per patient to 1.16 post-operatively (P,<,0.0001). Twenty-seven averaged 1.52 inflammatory or infectious post-operative complications per patient, 19 averaged 1.47 stomal complications, and 11 averaged 2.09 ileovesicostomy mechanical obstructions. Overall, 27 required 2.85 re-operations or additional procedures following ileovesicostomy. Sub-group analysis identified BMI (P,=,0.0569) as a possible risk factor. Differences in outcomes based on age, tobacco use, diabetes, neurogenic bladder etiology, pre-operative indwelling catheterization, or urethral closure were not significant. Conclusions Ileovesicostomy is a valuable management option for adults with neurogenic bladder unable to perform intermittent catheterization. The incidence of urinary tract comorbid events significantly decreased following ileovesicostomy though the onset of other complications should be considered. The morbidity associated with ileovesicostomy requires careful patient selection, close long-term follow-up, and potential subsequent interventions to address post-operative complications. Neurourol.

[source] Follow-Up Recommendations for Benign Breast BiopsiesTHE BREAST JOURNAL, Issue 5 2006Susanna Shin MD Abstract: Histologically proven benign breast disease increases a woman's relative risk for subsequent cancer development. Yet follow-up guidelines for mammogram and clinical breast examination after a benign breast biopsy are lacking. Our objective was to determine if increased surveillance is indicated following a benign breast biopsy. Following institutional review board approval, a retrospective database review was conducted of prospectively gathered patients who had a benign breast biopsy (core or excisional) for an abnormality detected on mammogram, ultrasound, or clinical breast examination. Follow-up, for all subjects, was a clinical breast examination and mammogram or ultrasound at 6 months, 1 year, and 2 years after benign breast biopsy by a breast surgeon. End points were the need for additional biopsies or cancer detection. Statistical analysis was performed using chi-squared analysis. From January 2000 to July 2003, 156 patients age 18,86 years had a benign breast biopsy. During the 2 year follow-up, 20 patients (13%) required a subsequent biopsy. No significant difference was observed in mean age, race, menarche, menopause, parity, age at first live birth, use of oral contraceptives, history of prior biopsy, or the pathology of the initial lesion between those who needed a subsequent biopsy and those who did not. Seven excisional biopsies were performed (one at 6 months, four at 1 year, and two at 2 years follow-up) for growth of the benign breast biopsy lesion, and pathology remained concordant with the original diagnosis. Thirteen biopsies were done for new findings on mammogram or ultrasound. Three of these (1.9%) yielded a cancer diagnosis (one at 6 months, one at 1 year, and one at 2 years follow-up). No new lesions were identified on follow-up by clinical breast examination alone. Increased surveillance following a benign breast biopsy is necessary because of the increased need for subsequent biopsy or risk of cancer development. This should include imaging (mammography or ultrasound) and a clinical breast examination 6 months, 1 year, and 2 years after a benign breast biopsy. [source] Hospital Use in the Treatment of Sleep Apnea,THE LARYNGOSCOPE, Issue 3 2004Erik J. Petersen MD Abstract Objectives Evaluate hospital use for treatment of sleep apnea. Study Design Retrospective database review. Materials and Methods The 1998 to 2000 National Inpatient Sample (NIS) was searched for admissions with a diagnosis of sleep apnea. Records were examined for demographics, diagnoses, procedures, and complications. Data were analyzed to identify factors affecting length of stay (LOS) and charges. Results There were 5,864 (0.03% NIS) admissions for sleep apnea. The sleep apnea group had lower mean age (43.1 vs. 47.2 years), higher percentages of males (71.6% vs. 41.0%) and African Americans (18.7% vs. 13.7%), and higher rates of obesity, hypertension, and anatomic airway diagnoses than the NIS population. Of sleep apnea group adults, 77.1% underwent a mean 2.3 procedures, whereas of those patients under 18 years of age, 60.8% underwent a mean of 1.2 procedures. Tracheotomy and procedures for hypopharyngeal airway compromise were used infrequently. Within the sleep apnea group, there were significant differences in LOS and charges on the basis of age, sex, race, payment method, procedures, and number of secondary diagnoses (all P < .05). Patients over 18 admitted for other diagnoses, but with secondary diagnosis of sleep apnea, had longer LOS (5.38 vs. 4.95 days) and higher charges ($16,562 vs. $13,928) than patients without sleep apnea. Conclusions Hospital use for sleep apnea remains largely for surgical treatment of the disease. Procedures directed at hypopharyngeal obstruction are seldom used. Multiple factors including patient age, number of secondary diagnoses, and procedures affect LOS and charges. The presence of sleep apnea also increases charges and LOS in patients admitted for other diagnoses. [source] Patterns of Maxillofacial Injuries As a Function of Automobile Restraint Use,THE LARYNGOSCOPE, Issue 4 2000M. Scott Major MD Abstract Objective To determine the pattern and severity of maxillofacial injuries sustained in a motor vehicle accident (MVA) resulting from automobile restraint use. Design Retrospective database review of patients injured in a MVA who were admitted to the level I trauma center at the University of Louisville Hospital in Louisville, Kentucky. Methods Demographic data, drug and alcohol impairment screening, and comorbidity data were obtained from database searches of trauma records. Forty-four patients had an airbag deployed, 34 patients wore seat belts, and 94 patients were unrestrained. All maxillofacial Abbreviated Injury Scale (AIS) ratings were compared among the three groups. Results Twenty-two of the 44 patients (50%) in the airbag group sustained only facial injuries. Fifteen of them had lacerations; four others had only facial abrasions. Three of the airbag patients had moderate facial injuries (AIS = 2); none required operative management. The airbag group had a mean AIS rating of 1.13, the seat belt group a mean AIS of 1.29, and the unrestrained group a mean AIS of 1.46. Patients using either seat belts (mean age, 40.5 y) or airbags (mean age, 44.9 y) were older than the unrestrained group (mean age, 39.6 y). Drug and/or alcohol impairment was significantly greater in the unrestrained group (mean, 38%) compared with the seat belt group (mean, 26%) and the airbag group (mean 11%). Conclusions Use of airbags is associated with less severe maxillofacial injuries compared with either a seat belt alone or no restraint. There is an inherent risk of minor maxillofacial injuries with airbag usage, but the severity of injury is distinctly reduced. [source] | ||||||||||
