Comprehensive laparoscopic approach to pediatric varicocele based on preoperative color Doppler ultrasound assessment
2008
Abstract: Background This study aimed to assess whether laparoscopic treatment for any kind of varicocele is possible after preoperative identification of refluxing veins by color Doppler ultrasound (CDUS). Methods At the authors'' institution, 98 patients with a median age of 11.3 years (range, 7.1-16 years) were evaluated for a left varicocele. Preoperatively, all the patients underwent ultrasound scan assessment of testicular volume and CDUS to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. In all the patients, laparoscopic division of the spermatic artery and veins was performed as close as possible to the internal inguinal ring. The other…
Predictors of microvascular complications in type 1 diabetic patients at onset: The role of metabolic memory
2011
Background Several epidemiological studies showed a close association between metabolic control and microvascular complications in type 1 Diabetes Mellitus (T1DM). The aim of our longitudinal observational study was to evaluate the predictive role of the main clinical and biochemical parameters in determining microvascular complications. Methods 376 T1DM patients, hospitalized in our division from 1991 to 2005 (mean follow-up = 10.93 ± 4.26 years) were studied. Stepwise Cox regression analysis was used to identify the influence of residual ß-cell function, ß-cell autoimmunity, HbA1c levels and other clinical and laboratory parameters in the development of microalbuminuria and retinopathy.

Enuresis Subtypes Based on Nocturnal Hypercalciuria: A Multicenter Study
2003
Purpose: Desmopressin may not be effective for nocturnal enuresis associated with polyuria and hypercalciuria. Nighttime hypercalciuria in an enuretic population from 5 centers and its correlation with nighttime polyuria were verified. Materials and Methods: A total of 450 enuretic patients (278 males, 172 females, mean age 9.7 years) were evaluated with 72-hour micturition charts, urinalysis, serum creatinine and osmolarity, diurnal and nocturnal electrolytes with fractional Na+ and K+ urinary excretion, and nocturnal (4 a.m.) plasma vasopressin. Creatinine electrolytes and osmolarity were measured in daytime (8 a.m. to 8 p.m.) and nighttime (8 p.m. to 8 a.m.) urine volumes. Patients were …
Antibiotic single-dose prophylaxis of shunt infections.
1989
Shunt infections after implantation or revision of a shunt for CSF drainage in hydrocephalic patients are serious complications. In view of their frequency, this study investigated the efficacy of prophylactic administration of a single dose of the antibiotic cefazedone in reducing in the post-operative infection rate. Fifty children of up to 14 years of age suffering from hydrocephalus of various etiologies were treated prophylactically and compared with a similar untreated group. The diagnosis of infection was based mainly on microbiological and clinical observations and investigations. Classical infection parameters were also recorded and evaluated, but played only a secondary role in es…
Treatment of acute mastoiditis in children with cochlear implants
2009
Abstract Introduction Acute mastoiditis (AM) is a paediatric infectious complication that raises a specific problem in case of implanted patients. Objective To review the cases of AM in a paediatric cochlear implant (CI) programme to study its incidence and associated problems. Materials and methods A retrospective study was conducted on 248 children aged between 8 months and 14 years who underwent CI from 1994 to 2009. The demographics, clinical data and their treatment were analyzed. Results Five patients developed acute mastoiditis (2.01%), three of them with subperiosteal abscess (1.21%). The mean age of implantation was 2 years and 4 months, and the complication presented between 1 and…
Series of fibrinous inflammation after implantation of capsular tension rings
2014
Purpose To analyze the cause of fibrinous inflammation in eyes with capsular tension rings (CTRs) after cataract surgery. Setting Department of Ophthalmology, University Medical Center, Johannes Gutenberg-University Mainz, Mainz, Germany. Design Retrospective case series. Methods High-performance liquid chromatography was implemented to eliminate impurities. One CTR was explanted for microbiologic examination. The pH values of the CTR and the storage solution were analyzed, Seldi and Maldi tests were performed, as well as toxicity tests with immortal cell lines. Material batches were analyzed. The organic carbon content of CTRs, detergents, and storage solutions was checked. The presence of…
Preoperative risk factors for postoperative delirium (POD) after urological surgery in the elderly
2011
The aim of this observational study was to investigate the occurrence of postoperative delirium (POD) in elderly patients undergoing urological surgery and to identify those factors associated with delirium. Ninety consecutive patients (81 males and 9 females; average age of 74.3 ± 0.40 years), undergoing urological surgery in University-Hospital Urological Clinic were selected. Personal, medical, cognitive and functional data, biochemical parameters, preoperative medications, conduct of surgery and anesthesia and details of hemodynamic control were collected as predictors of delirium. After surgery, the subjects were divided on the basis of delirium onset within a week observation period. …
Risk factors for postoperative delirium after colorectal surgery for carcinoma
2011
Background and aim: Data regarding the incidence and risk factors for postoperative delirium (PD) after gastrointestinal surgery are heterogeneous because they include both benign and malignant disease. The aim of this study was to investigate the incidence and risk factors for PD in 100 consecutive patients over 65 years who underwent colorectal surgery for carcinoma. Methods: Pre-operative cognitive function was assessed using the Mini Mental State Examination. The onset of PD was diagnosed by the Confusion Assessment Methods administered to the patients every 12 h starting from the first postoperative day to discharge. The severity of PD was also evaluated with the Delirium Rating Scale.…
Antihypertensive activity of angiotensin II AT1 receptor antagonists: a systematic review of studies with 24 h ambulatory blood pressure monitoring.
2007
To perform a systematic review of the antihypertensive activity of the angiotensin II AT1 receptor antagonists (ARB).Studies in which blood pressure (BP) was measured using ambulatory BP monitoring for at least 24 h were collected from MEDLINE. Data for each treatment group, ARB, placebo or the drug used for its comparison were obtained from the selected studies. Only studies with a minimum of quality criteria were selected. The final study group contained 36 publications, with a total of 47 patient cohorts receiving ARB in monotherapy, 10 with placebo, 10 with amlodipine, and five with enalapril. The reduction in clinical and ambulatory BP during 24 h, day, night and the last 4-h period fo…
Report on Intrauterine Drug Exposure During Second Trimester of Pregnancy in a Heroin-Associated Death
1999
A 17-year-old girl was found dead in a public toilet with fresh needle puncture marks. She was 18-20 weeks pregnant with a male fetus. Drug screening of her blood and urine indicated recent heroin use. Chronic drug use was confirmed by hair analysis. Amniotic fluid as well as fetal and maternal tissues and body fluids were analyzed by GC/MS and HPLC. All the fetal specimens were investigated, and the following levels of drugs were found: 6-monoacetyl-morphine (blood: 152 ng/g; amniotic fluid: 128 ng/g; brain: 140 ng/g; lung: 110 ng/g; liver: 2 ng/g; kidney: 40 ng/g), morphine (blood: 1360 ng/g; amniotic fluid: 604 ng/g; brain: 710 ng/g; lung: 1030 ng/g; liver: 2060 ng/g; kidney: 1100 ng/g),…
