Relation between electroconvulsive therapy, cognitive side effects, neuron specific enolase, and protein S-100

To systematically investigate obsessive-compulsive traits in Parkinson's disease, patients were administered the Maudsley obsessional-compulsive inventory (MOCI) and a modification of the Leyton obsessional inventory (LOI) to a sample of non-demented and non-depressed patients with Parkinson's disease. Patients with severe Parkinson's disease showed more obsessive traits than normal controls in MOCI and LOI total scores, and in the "checking", "doubting", and "cleaning" subscales of the MOCI. By contrast, patients with mild disease did not differ from controls. A significant correlation was found between severity and duration of illness and MOCI total score. These results support the involvement of basal ganglia in obsessive-compulsive symptomatology. As patients with mild Parkinson's disease did not differ from controls, obsessive-compulsive disorder does not seem to be directly related to the initial nigrostriatal dopaminergic deficiency which causes clinical Parkinson's disease symptomatology. The appearance of obsessive symptoms could be related to the subset of neurochemical changes taking place at the level of the basal ganglia circuitry as disease progresses.     

Hepatic derangement following N‐Acetylcysteine enemas in an infant with cystic fibrosis

We discuss an infant with MI secondary to cystic fibrosis, who was managed surgically by a double barrel ileostomy for mid – small bowel atresia and developed severe faecal impaction in the post – operative period. The faecal impaction was treated successfully with oral NAC and 0.2% NAC contrast enemas. The patient's liver function tests revealed a dramatic increase in transaminases and bilirubin contemporaneous with the administration of the enemas. The levels showed a spontaneous improvement after discontinuation. This is only the second reported case of hepatotoxicity secondary to NAC enemas in the literature. While our experience offers modest support for the use of NAC, its efficacy is not yet proven and paediatric surgeons using NAC in the enema form need to closely monitor liver function contemporaneous with this agent's administration and adjust their treatment accordingly.     

Urinary albumin excretion rate and puberty in non-diabetic children and adolescents

Slightly elevated urinary albumin excretion rate (microalbuminuria) is a marker of early diabetic nephropathy, but it is unclear if the established definition of microalbuminuria (20–200 μg/min) is correct for children and adolescents. We investigated the albumin excretion rate, albumin/creatinine ratio and urinary albumin concentration in 150 healthy schoolchildren and adolescents to (a) obtain a reference value for albumin excretion rate, (b) relate albumin excretion to pubertal stages and (c) evaluate albumin/creatinine ratio and morning albumin concentration as screening methods for elevatcd albumin excretion rate. Albumin concentration was measured by immunoturbidimetry in timed overnight urine samples. The albumin excretion showed a skewed distribution (geometric mean 3.2 μg/min, 95 percentile 15.1 μg/min). In girls, a peak in the albumin excretion rate was found at the pubertal stage 4 (Tanner) and in boys at stage 5. Albumin/creatinine ratio of 2.5 mg/mmol as a scrccning level for elevatcd albumin cxcrction (15 μg/min) showed a high positivc (0.88) and negative (0.99) predictive value.     

Prediction of survival in extrahepatic biliary atresia by hepatic duplex sonography

BACKGROUND: The clinical course of biliary atresia patients is extremely variable. To optimize conservative treatment and correctly schedule liver transplantation, noninvasive investigations that are predictive of individual survival and that can be performed regularly are needed. In this study, the prognostic value of Doppler sonography was investigated in these patients. METHODS: Thirty biliary atresia patients (age range, 1 month to 15.2 years; mean, 4.0 years) and 38 control subjects underwent standardized Doppler sonography of liver and spleen. Biochemical tests of liver function and of fibrogenesis were performed in parallel. Individual clinical outcome was registered 1 and 2 years later. RESULTS: In control subjects, maximum portal flow velocity (Vmax) was more than 16 cm/sec, and the hepatic vein flow pattern was triphasic. Among children with biliary atresia, those with diminished portal Vmax, a flattened hepatic vein flow curve, or a hepatic artery resistance index of 0.8 or more had significantly lower indices of hepatic protein synthesis (albumin, cholinesterase), higher bilirubin levels, and higher concentrations of markers of connective tissue turnover (procollagen peptides, laminin P1) than did those with normal Doppler sonography measurements. The rate of survival without transplantation during the following 2 years was significantly lower in children with abnormal Doppler findings. From portal and hepatic vein flow measurements, patient survival 2 years later could be predicted with an accuracy of 93%. CONCLUSIONS: In children with extrahepatic biliary atresia, Doppler sonography of the hepatic blood flow is a noninvasive indicator of disease severity. Moreover, it allows a highly accurate prediction of patient survival for the following 2 years.     

Complete rupture of the urethra in combination with anterior pelvic fracture and symphyseal rupture after spontaneous vaginal delivery

Summary We report on a complete longitudinal rupture of the urethra in combination with a rupture of the pubic symphysis and pelvic fracture during spontaneous vaginal delivery. Only after stabilisation of the pelvic fracture by external skeletal fixation adaptation of the urethra was possible. Three weeks later after removing of the transurethral catheter a mild stress incontinence could be observed. In the follow up one year later the patient was completely continent. The cosmetic result was satisfactory. There was no cystocele. An unclear haematuria after delivery needs a meticulous urological examination. Early repair of urethral disruption minimize the risk of severe incontinence. Coordinated care between the trauma surgeon and urologist is required for successful treatment of this rare combined injury after birth.      

Traumatic death in urban children

Trauma has remained one of the leading causes of death in children in spite of improved medical care. A review of 911 pediatric trauma deaths which occurred over a 5 yr period in an urban setting revealed that almost 50% of these children died before receiving medical care. A significant improvement of the trauma mortality can thus only be accomplished by reducing the number of “DOAs”. We therefore analyzed the cause and type of injury and its relationship to age, sex, race, seasonal occurrence, and sociological circumstances. The following four categories are merely part of the overall material developed in this review. Even with improved medical care of trauma patients the overall pediatric trauma mortality cannot be significantly reduced unless the number of DOAs is decreased through prevention. Educational and family assistance programs can be designed for specific problem areas to reach identified susceptible groups through existing channels such as day care centers, schools, or welfare agencies. Statistical data, such as presented here (but not previously available) are essential to analyze the particular problems of specific geographic and sociologic areas. Since the vast majority of pediatric trauma deaths fall within the interest sphere of the pediatric surgeon, our active participation in accident prevention is essential to achieve a significant reduction of pediatric trauma mortalities.     

Active surveillance with selective delayed intervention using PSA doubling time for good risk prostate cancer

Good risk prostate cancer, defined as patients with a Gleason score of 6 or less, PSA<10-15, and T1c-T2a, now constitutes 50% of newly diagnosed prostate cancer. For most of these patients, the disease is indolent and slow growing. There is substantial evidence that it does not pose a threat during the lifetime of most patients. The challenge is to identify those patients who are not likely to experience significant progression while offering radical therapy to those who are at risk. To date, molecular markers have failed to provide sufficiently reliable predictive information to influence decision making. The approach to favorable risk prostate cancer described in this article uses estimation of PSA doubling time (PSA DT) to stratify patients according to the risk of progression. Patients who select this approach are managed initially with active surveillance. those who have a PSA DT of 3 years or less (based on a minimum of 3 determinations over 6 months) are offered radical intervention. The remainder are closely monitored with serial PSA and periodic prostate re-biopsies (at 2, 5, and 10 years). In this series of 299 patients, the median doubling time was 7.0 years. 42% had a PSA DT>10 years, and 20% had a PSA DT>100 years. The majority of patients in this study remain on surveillance. The approach of active surveillance with selective delayed intervention based on PSA DT represents a practical compromise between radical therapy for all (which results in overtreatment for patients with indolent disease), and watchful waiting with palliative therapy only (which results in undertreatment for those with aggressive disease).
