Functional intraperineal pouch of rectal wall (posterior rectocele)

We have identified 18 cases of functional pouch of the posterior rectal wall visualized by defecography. In the absence of previous evidence in the literature, we named this anomaly posterior rectocele and studied it from the clinical, radiologic, and endoscopic points of view.     

Amyotrophic lateral sclerosis and frontotemporal dementia: A behavioural and cognitive continuum

Our objective was to compare the cognitive and behavioural profile of patients with amyotrophic lateral sclerosis (ALS) and behavioural variant frontotemporal dementia (bvFTD), and to explore the continuum between these disorders according to neuropsychological and behavioural performance using novel methods of testing and analysis. Twenty patients with ALS, 20 bvFTD patients and 20 healthy controls completed a neuropsychiatric and neuropsychological assessment including cognitive screening, working memory, inhibitory control, decision making and emotion recognition. The resulting neuropsychological and behavioural data were analysed by Rasch analysis. ALS patients showed a similar profile to bvFTD patients on tests of working memory, inhibitory control and behavioural measures. Nine ALS patients (45%) had cognitive impairment and five (25%) met criteria for bvFTD. Even in a subset of MND patients with no impairment on the ACE-R, subtle impairment of inhibitory control together with moderate to severe apathy, were found. The Rasch analysis confirmed that all patients could be ranked on the same continuum, based on their neuropsychological performance and behaviour. Thus, the cognitive and behavioural profiles of ALS mirror those seen in bvFTD. Impaired inhibitory control and behavioural changes suggest subtle orbitofrontal dysfunction in ALS. The Rasch analysis revealed a clear overlap between bvFTD and ALS.     

Orofacial Granulomatosis: Clinical Signs of Different Pathologies

Orofacial granulomatosis (OFG) is an uncommon disease characterized by persistent or recurrent soft tissue enlargement, oral ulceration and a variety of other orofacial features. It could be an oral manifestation of a systemic disease. For a correct differential diagnosis, local and systemic conditions characterized by granulomatous inflammation should be excluded using appropriate clinical and laboratory investigations. In fact, the diagnosis of OFG may be confirmed only by histopathological identification of noncaseating granulomas. The literature from 1943 to 2014 was reviewed with emphasis on the etiology of OFG and on clinical manifestations of systemic pathologies associated with OFG. The precise cause of OFG is still unknown, although several theories have been suggested, such as infection, hereditary factors and allergy. OFG is a disease that has a wide spectrum of presentation, which may include the oral manifestation of a systemic condition such as Crohn''s disease, sarcoidosis, granulomatosis with polyangiitis and Melkersson-Rosenthal syndrome.Key Words: Orofacial granulomatosis, Inflammatory bowel disease, Crohn''s disease, Sarcoidosis, Granulomatosis with polyangiitis, Melkersson-Rosenthal syndrome     

Intraperitoneal calcitriol in infants on peritoneal dialysis.

BACKGROUND: Calcitriol has long been used as the main therapy in renal osteodystrophy, but the efficacy of the oral route is not always as high as expected. OBJECTIVE: To asses the safety and efficacy of intraperitoneal calcitriol in infants undergoing peritoneal dialysis (PD). PATIENTS AND METHODS: PD patients on oral calcitriol therapy, with serum parathyroid hormone (PTH) >1000 pg/mL during the previous 3 months of treatment, were switched to intraperitoneal calcitriol therapy, 1 microg twice per week. Dose was increased to 1 microg three times per week if PTH remained >1000 pg/mL, and was later readjusted. Target PTH was 200-300 pg/mL according DOQI guidelines. STATISTICS: All results are expressed as mean +/- SE. The Wilcoxon signed rank test was used to evaluate differences in measurements for each pair of values. The confidence interval for differences between population medians was 96.9%. A p value less than 0.05 was considered significant. RESULTS: Six male children, mean age 17 +/- 3.86 months, completed a 12-month follow-up. Mean pretreatment PTH was 1654 +/- 209 pg/mL. Mean PTH at months 0, 3, 6, 9, and 12 was 1448 +/- 439*, 1277 +/- 723, 910 +/- 704, 582 +/- 282*, and 465 +/- 224* pg/mL, respectively (*p < 0.05). Twelve hypercalcemic and 10 hyperphosphatemic episodes were successfully treated. CONCLUSION: Infants on PD who fail to respond to oral calcitriol therapy can be safely treated with intraperitoneal administration of active vitamin D.     

Patient identification errors: The detective in the laboratory

BackgroundThe eradication of errors regarding patients' identification is one of the main goals for safety improvement. As clinical laboratory intervenes in 70% of clinical decisions, laboratory safety is crucial in patient safety. We studied the number of Laboratory Information System (LIS) demographic data errors registered in our laboratory during one year.MethodsThe laboratory attends a variety of inpatients and outpatients. The demographic data of outpatients is registered in the LIS, when they present to the laboratory front desk. The requests from the primary care centers (PCC) are made electronically by the general practitioner. A manual step is always done at the PCC to conciliate the patient identification number in the electronic request with the one in the LIS. Manual registration is done through hospital information system demographic data capture when patient's medical record number is registered in LIS. Laboratory report is always sent out electronically to the patient's electronic medical record. Daily, every demographic data in LIS is manually compared to the request form to detect potential errors.ResultsFewer errors were committed when electronic order was used. There was great error variability between PCC when using the electronic order.ConclusionsLIS demographic data manual registration errors depended on patient origin and test requesting method. Even when using the electronic approach, errors were detected. There was a great variability between PCC even when using this electronic modality; this suggests that the number of errors is still dependent on the personnel in charge of the technology.
