Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists…

BACKGROUND: Cognitive fatigue (CF) is a common complaint in persons with MS (PwMS). Fampridine-SR improves ambulation, fatigue and endurance, due to enhancing action potential formation by blocking potassium channels in demyelinated axons. Thus, through this same mechanism, it is hypothesized that Fampridine-SR could i…

The chemo-thermal oxidation method at 375°C (CTO-375) has been widely used to quantify black carbon (BC) in sediments. In the present study, CTO-375 was tested and adapted for application to soil, accounting for some matrix specific properties like high organic carbon (≤ 39%) and carbonate (≤ 37%) co…

Hypocalcemia due to hypoparathyroidism (HPT) is a late complication of iron-overloaded patients with b-thalassaemia major (TM). The majority of patients have mild disease with parasthesias, while in the more severe form tetany, seizures or cardiac failure may occur. In the last 20 years we observed heart failure in 2 o…

Over the last 20 years at the Rizzoli Orthopaedic Institute in Bologna 20 cases of chondrosarcoma (CS) of the thoracic wall (14 males, 6 females, mean age 49 years) have been submitted to surgery. Localization was costal in 11 cases, costosternal in 3, sternal in 3, costovertebral in 3. The most frequent histological v…

OBJECTIVE: The aim of this study was to evaluate suicide attempts in pediatric population and analyze the morbimortality. PATIENTS AND METHODS: We have reviewed thirty reports from twenty six patients hospitalized in UCIP by suicide attempts with an average age of 15.5 years (range 11-19) between January 1991 and Apri…

Very few reports in the literature have dealt with lumbar disc herniation in the elderly and its treatment by chymopapain chemonucleolysis. Between September 1981 and May 1991, 42 patients aged between 60 and 80 years were treated by chemonucleolysis for lumbar disc herniation. The clinical symptoms and signs, similar…

A total population study of children, aged 13 years and under, suggested that there has been an apparent rise in the frequency of autistic disorder and autistic-like conditions (excluding Asperger's syndrome) in one area of western Sweden over the last ten years. The frequency was 4.0/100,000 in 1980, 7.5/10,000 in 198…

Sixteen hospitalized patients, aged between 10 and 76 years (mean: 34.3 years), with bacterial meningitis were treated i.v. with cefoperazone at daily doses of 4.5 g to 9 g. In two cases ampicillin was given in combination with cefoperazone during the last four days and the first five days of treatment, respectively. T…

From a total of 1,152 consecutive patients with heart valve replacement (1964-87) 108 patients (9.4%) had to be reoperated. Mechanical valves had to be replaced (n = 89) mainly because of perivalvular leakage followed by prosthetic stenosis and dysfunction. The lowest reoperation rate was found with Björk-Shiley p…

For 30 years, GH deficient children have been treated with human GH. Earlier, therapy was given by intramuscular injections, but recently subcutaneous injections have been used. For the last few years, many children have been given daily injections, which have proved more effective. The form in which GH is supplied and…

This paper represents a historical analysis of the results achieved by esophageal cancer surgery over the last three decades, as they appear in the literature of the years 1954-1985, and in our own experience between 1965 and 1985, with the aim of assessing the evolution of operative mortality and long-term survival. I…

20 medulloblastomas in children were treated at the Neurosurgical Department of Perugia over the last 6 years. The age ranged between 1.2 and 15 years, with a mean of 8 years. The ratio between males and females was 3/1. Only three tumors were localized within one cerebellar hemisphere. A shunt was performed before the…

Eighty-five eyes with severe vitreous hemorrhage on initial visit were followed for three to ten years without treatment. A comparison of initial and final visual acuities showed vision to have worsened in 36 eyes (42%), improved in 25 eyes (30%) and remained unchanged in 24 eyes (28%). Vision in 60 eyes was 5/200 or w…

BACKGROUND & AIMS: Screening colonoscopies are of uncertain benefit for persons with negative results from a fecal immunochemical test (FIT). We investigated detection of CRC by colonoscopy in asymptomatic, average-risk, FIT-negative subjects. METHODS: We conducted a retrospective, population-based cohort study of 96,…

The aim of the study was to evaluate the effectiveness and toxicity of CyberKnife (CK) stereotactic radiosurgery (SRS) and stereotactic ablative radiation therapy (SABR) of patients with prostate cancer bone metastases. Analysis of prognostic and predictive factors was also performed. Material consisted of 51 patients…

Doxylamine succinate, one of the antihistamines available without a prescription for patients suffering from insomnia, is also an antihistamine with the potential for abuse. Although there are case reports about the addictive potential of antihistamines, there are not many studies on doxylamine succinate addiction in t…

Surfactant crystals can stabilize liquid foams. The crystals are adsorbed at bubble surfaces, slowing down coarsening and coalescence. Excess crystals in the liquid channels between bubbles arrest drainage, leading to ultrastable foams. The melting of crystals upon raising the temperature allows thermoresponsive foams…

Hip arthroscopy has evolved significantly over the last 5 to 10 years. With this comes the burden of patients with continued pain after their index procedure. Reasons for the need for revision surgery can be many, including incomplete resection of impingement morphology, unrecognized/unaddressed acetabular dysplasia or…
