Impact of benign childhood epilepsy with centrotemporal spikes (BECTS) on school performance

BECTS represents the vast majority of childhood focal epilepsy. Owing to the age peculiarity of children who suffer from this disease, i.e., school-going age of between 6 and 9 years, the condition is often referred to as a school disorder by parents and teachers. Objective: The aim of this study was to evaluate the academic performance of children with BED'S, according to the clinical and electroencephalographic ILAE criteria, and compare the results of neuropsychological tests of language and attention to the frequency of epileptic discharges. Methods: The performances of 40 school children with BED'S were evaluated by applying a school performance test (SBT), neuropsychological tests (WISC and Trail-Making), and language tests (Illinois Test Psycholinguistic Abilities - ITPA - and Staggered Spondaic Word - SSW). The same tests were applied in the control group. Results: Children with BED'S, when compared to those in the control group, showed lower scores in academic performance (SPT), digits and similarities subtests of WISC, auditory processing subtest of SSW, and ITPA - representational and automatic level. The study showed that epileptic discharges did not influence the results. Conclusion: Children with BED'S scored significantly lower scores in tests on academic performance, when compared with those in the control group probably due to executive dysfunction.

Postural Control in Older Patients with Benign Paroxysmal Positional Vertigo

Objective. To evaluate the effectiveness of a canalith-repositioning procedure in postural control of older patients with idiopathic benign paroxysmal positional vertigo (BPPV). Study Design. Prospective clinical trial. Setting. A tertiary referral center. Methods. A 9-month follow-up survey with a prospective design was conducted among 33 older patients with BPPV. Patients underwent static posturography (Balance Rehabilitation Unit [BRU]) and were administered the Dizziness Handicap Inventory (DHI) before and after the maneuver. After the treatment, they were compared with 33 healthy older subjects. The posturography parameters were the limit of stability (LOS), the center of body-pressure area (COP), and the velocity of oscillation (VOS) under conditions of visual, somatosensory, and visual-vestibular conflict. Results. One canalith-repositioning procedure relieved most patients' complaints (54.5%), and 100% were relieved with 1 to 3 maneuvers. Total DHI score and all subscales improved after treatment (P < .01). The LOS values pretreatment (mean [SD] 134.27 [55.32] cm(2)) and posttreatment (181.03 [47.79] cm(2)) were significantly different (P < .01). Comparative analysis of COP values showed a relevant statistical difference in 8 of 10 postmaneuver conditions (P < .01). The postmaneuver VOS showed a significant difference under 7 conflict conditions. There were no differences between the healthy older subjects and treated patients for all VOS values under all conditions and for COP values under 9 conditions. Conclusion. The canalith-repositioning procedure promotes remission of symptoms, an increase in LOS, and improvement in postural control under conditions of somatosensory and visual conflict and visual-vestibular interaction.

Intraoral carcinosarcoma on the floor of the mouth mimicking a benign lesion

Carcinosarcoma is a rare malignant disease with aggressive behaviour rarely producing oral manifestations. This article reports a case of an intraoral carcinosarcoma affecting a 71-year-old black male; the diagnosis was made by histopathological and immunohistochemical analyses. Computed tomography scanning showed metastatic masses in the lungs. The patient was underwent a chemotherapy protocol regimen, but died as a consequence of the disease within 10 months of diagnosis. Distinctive characteristics of this presentation were the location of the lesion (floor of the mouth) and its clinical features resembling a benign lesion. A brief review of intraoral carcinosarcoma cases in the literature is also presented.

Genotype analysis of the human endostatin variant p.D104N in benign and malignant adrenocortical tumors

OBJECTIVE: Endostatin is a potent endogenous inhibitor of angiogenesis. It is derived from the proteolytic cleavage of collagen XVIII, which is encoded by the COL18A1 gene. A polymorphic COL18A1 allele encoding the functional polymorphism p.D104N impairs the activity of endostatin, resulting in a decreased ability to inhibit angiogenesis. This polymorphism has been previously analyzed in many types of cancer and has been considered a phenotype modulator in some benign and malignant tumors. However, these data are controversial, and different results have been reported for the same tumor types, such as prostate and breast cancer. The purpose of this study was to genotype the p.D104N variant in a cohort of pediatric and adult patients with adrenocortical tumors and to determine its possible association with the biological behavior of adrenocortical tumors. METHODS: DNA samples were obtained from 38 pediatric and 56 adult patients (0.6-75 yrs) with adrenocortical tumors. The DNA samples were obtained from peripheral blood, frozen tissue or paraffin-embedded tumor blocks when blood samples or fresh frozen tissue samples were unavailable. Restriction fragment length polymorphism analysis was used to genotype the patients and 150 controls. The potential associations of the p.D104N polymorphism with clinical and histopathological features and oncologic outcome (age of onset, tumor size, malignant tumor behavior, and clinical syndrome) were analyzed. RESULTS: Both the patient group and the control group were in Hardy-Weinberg equilibrium. The frequencies of the p.D104N polymorphism in the patient group were 81.9% (DD), 15.9% (DN) and 2.2% (NN). In the controls, these frequencies were 80.6%, 17.3% and 2.0%, respectively. We did not observe any association of this variant with clinical or histopathological features or oncologic outcome in our cohort of pediatric and adult patients with adrenocortical tumors.

Standard surgical treatment for benign prostatic hyperplasia is safe for patients over 75 years: Analysis of 100 cases from a high-volume urologic center

OBJECTIVES: In this study, we aimed to determine the complications of standard surgical treatments among patients over 75 years in a high-volume urologic center. METHODS: We analyzed 100 consecutive patients older than 75 years who had undergone transurethral prostatic resection of the prostate or open prostatectomy for treatment of benign prostatic hyperplasia from January 2008 to March 2010. We analyzed patient age, prostate volume, prostate-specific antigen level, international prostatic symptom score, quality of life score, urinary retention, co-morbidities, surgical technique and satisfaction with treatment. RESULTS: Median age was 79 years. Forty-eight patients had undergone transurethral prostatic resection of the prostate, and 52 had undergone open prostatectomy. The median International Prostatic Symptom Score was 20, the median prostate volume was 83 g, 51% were using an indwelling bladder catheter, and the median prostate-specific antigen level was 5.0 ng/ml. The most common comorbidities were hypertension, diabetes and coronary disease. After a median follow-up period of 17 months, most patients were satisfied. Complications were present in 20% of cases. The most common urological complication was urethral stenosis, followed by bladder neck sclerosis, urinary fistula, late macroscopic hematuria and persistent urinary incontinence. The most common clinical complication was myocardial infarction, followed by acute renal failure requiring dialysis. Incidental carcinoma of the prostate was present in 6% of cases. One case had urothelial bladder cancer. CONCLUSIONS: Standard surgical treatments for benign prostatic hyperplasia are safe and satisfactory among the elderly. Complications are infrequent, and urethral stenosis is the most common. No clinical variable is associated with the occurrence of complications.

Botulinum Neurotoxin Type A for the Treatment of Benign Prostatic Hyperplasia: Randomized Study Comparing Two Doses

Purpose. To assess the efficacy and safety of intraprostatic injection of two botulinum neurotoxin type A (BoNT-A) doses for the treatment of benign prostatic hyperplasia (BPH). Materials and Methods. Men with symptomatic BPH who failed medical treatment were randomized to receive 100 U or 200 U of BoNT-A into the prostate. The International Prostatic Symptom Score (IPSS), maximum flow rate (Q(max)), post-void residual volume (PVR), PSA levels and prostate volume before injection and after 3 and 6 months were evaluated. Adverse events were compared between the groups. Results. Thirty four patients were evaluated, including 17 in the BoNT-A 100 U group and 17 in the BoNT-A 200 U group. Baseline characteristics were similar in both groups. Both doses produced significant improvements in IPSS, Q(max) and PVR after 3 and 6 months and both doses promoted comparable effects. Prostate volume was affected by 200 U BoNT-A injection only after 6 months of treatment. PSA levels were significantly affected in the 100 U group only after 6 months of treatment. In the 200 U group, PSA levels were significantly decreased after 3 and 6 months. The complication rate was similar in both groups. Conclusions. Efficacy and safety of both BoNT-A doses are similar for BPH treatment in the short term followup.

Immunolocalization of podoplanin in benign odontogenic tumours with and without ectomesenchyme

Objectives: To investigate podoplanin expression in epithelial odontogenic tumours with and without ectomesenchyme and verify the association between its immunoexpression and proliferative activity in keratocystic odontogenic tumours (KCOTS) and orthokeratinized odontogenic cysts (OOCs). Design: Eight ameloblastomas, nine adenomatoid odontogenic tumours, twenty KCOTS, five OOC, one calcifying epithelial odontogenic tumour, two ameloblastic fibromas, four ameloblastic fibro-odontomas and five calcifying cystic odontogenic tumours were immunohistochemically analysed with anti-podoplanin antibody. For KCOTS and OOC, the cell proliferation index was determined with Ki-67 immunostaining and compared by Spearman correlation coefficient. Results: Podoplanin was expressed in the peripheral odontogenic epithelium of most tumours. Ectomesenchyme was negative, except for odontoblasts. KCOTS exhibited positive podoplanin expression while in OOC it was absent/weak. There was statistically significant correlation ( p = 0.006) between podoplanin expression and cellular proliferation index of KCOTS and OOC. Conclusion: Podoplanin seems to be related to the proliferative activity of KCOTS and may have a role in the process of local invasion of odontogenic tumours with and without ectomesenchyme

Coexistence of benign phyllodes tumor and invasive ductal carcinoma in distinct breasts: case report

This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.

Design and synthesis of multipotent drugs: application to Alzheimer's disease and benign prostatic hyperplasia

The aim of this thesis was to synthesize multipotent drugs for the treatment of Alzheimer’s disease (AD) and for benign prostatic hyperplasia (BPH), two diseases that affect the elderly. AD is a neurodegenerative disorder that is characterized, among other factors, by loss of cholinergic neurons. Selective activation of M1 receptors through an allosteric site could restore the cholinergic hypofunction, improving the cognition in AD patients. We describe here the discovery and SAR of a novel series of quinone derivatives. Among them, 1 was the most interesting, being a high M1 selective positive allosteric modulator. At 100 nM, 1 triplicated the production of cAMP induced by oxotremorine. Moreover, it inhibited AChE and it displayed antioxidant properties. Site-directed mutagenesis experiments indicated that 1 acts at an allosteric site involving residue F77. Thus, 1 is a promising drug because the M1 activation may offer disease-modifying properties that could address and reduce most of AD hallmarks. BPH is an enlargement of the prostate caused by increased cellular growth. Blockade of α1-ARs is the predominant form of medical therapy for the treatment of the symptoms associated with BPH. α1-ARs are classified into three subtypes. The α1A- and α1D-AR subtypes are predominant in the prostate, while α1B-ARs regulate the blood pressure. Herein, we report the synthesis of quinazoline-derivatives obtained replacing the piperazine ring of doxazosin and prazosin with (S)- or (R)-3-aminopiperidine. The presence of a chiral center in the 3-C position of the piperidine ring allowed us to exploit the importance of stereochemistry in the binding at α1-ARs. It turned out that the S configuration at the 3-C position of the piperidine increases the affinity of the compounds at all three α1-AR subtypes, whereas the configuration at the benzodioxole ring of doxazosin derivatives is not critical for the interaction with α1-ARs.

ChronOS Inject in Children with Benign Bone Lesions – Does It Increase the Healing Rate?

Benign bone lesions in children although rare, can result in a pathological fracture. Although their etiology and pathogenesis are not yet entirely clear, the phenomenon of spontaneous healing is well known. Nevertheless, some benign bone lesions are unlikely to heal spontaneously due to the patient's age or high risk of fracture and deformity due to the lesion's location or size. The following study presents our results after treatment of these bone cysts with chronOS Inject.

Benign neonatal sleep myoclonus: a review of the literature

OBJECTIVE: Neurologically normal term infants sometimes present with repetitive, rhythmic myoclonic jerks that occur during sleep. The condition, which is traditionally resolved by 3 months of age with no sequelae, is termed benign neonatal sleep myoclonus. The goal of this review was to synthesize the published literature on benign neonatal sleep myoclonus. METHODS: The US National Library of Medicine database and the Web-based search engine Google, through June 2009, were used as data sources. All articles published after the seminal description in 1982 as full-length articles or letters were collected. Reports that were published in languages other than English, French, German, Italian, Portuguese, or Spanish were not considered. RESULTS: We included 24 reports in which 164 term-born (96%) or near-term-born (4%) infants were described. Neonatal sleep myoclonus occurred in all sleep stages, disappeared after arousal, and was induced by rocking the infant or repetitive sound stimuli. Furthermore, in affected infants, jerks stopped or even worsened by holding the limbs or on medication with antiepileptic drugs. Finally, benign neonatal sleep myoclonus did not resolve by 3 months of age in one-third of the infants. CONCLUSIONS: This review provides new insights into the clinical features and natural course of benign neonatal sleep myoclonus. The most significant limitation of the review comes from the small number of reported cases.

Chickenpox is not always benign: postvaricella purpura fulminans requires prompt and aggressive treatment

We present 2 patients, who were admitted owing to rapidly progressing purpuric lesions due to postvaricella purpura fulminans, a coagulopathy leading to life- or limb-threatening thrombosis caused by a severe transient autoimmune protein S deficiency. Laboratory results were being consistent with disseminated intravascular coagulation secondary to protein S deficiency; treatment with fresh frozen plasma, intravenous immunoglobulins, and prednisone was started. In our experience, a prompt therapy may limit the course and the extent of the disease. We present a review of the topic with supporting literature for the therapeutic options. Therefore, we should be reminded that purpura fulminans is a rare but severe complication of chickenpox, which demands quick action.
