Selected AbstractsLong-term effects of botulinum toxin A in children with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2 2009KRISTINA TEDROFF MD The long-term effects of botulinum toxin A (BoNT-A) treatment in children with cerebral palsy (CP) are still elusive. We studied a prospective clinical cohort of 94 children with different subtypes (50% spastic diplegic CP, 22% hemiplegic CP, 25% tetraplegic CP, 3% dyskinetic CP), sex (55% male, 45% female), severity according to Gross Motor Function Classification System (29% Level I, 15% Level II, 16% Level III, 17% Level IV, 23% Level V), and age (median 5y 4mo, range 11mo,17y 8mo). The longest follow-up time was 3 years 7 months (median 1y 6mo) and included a maximum of eight injections per muscle (median two injections to a specific muscle). Outcome measurements were muscle tone (Modified Ashworth Scale) and joint range of motion (ROM). Assessments were made at a minimum before and 3 months after each injection. Ninety-five per cent confidence intervals for differences from baseline were used to identify significant changes. BoNT-A injections induced reduction of long-term spasticity in all muscle-groups examined: the gastrocnemius, hamstring, and adductor muscles. The reduction in tone was most distinct in the gastrocnemius muscle, and each repeated injection produced an immediate reduction in muscle tone. However, improvement in ROM was brief and measured only after the first injections, whereupon the ROM declined. Thus, the results suggest that BoNT-A can be effective in reducing muscle tone over a longer period, but not in preventing development of contractures in spastic muscles. The dissociation between the effects on muscle tone and ROM indicates that development of contractures is not coupled to increased muscle tone only, but might be caused by other mechanisms. [source] Energy efficiency in gait, activity, participation, and health status in children with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 3 2008Claire Kerr BSc (Hons) Physio PhD The aim of the study was to establish if a relationship exists between the energy efficiency of gait, and measures of activity limitation, participation restriction, and health status in a representative sample of children with cerebral palsy (CP). Secondary aims were to investigate potential differences between clinical subtypes and gross motor classification, and to explore other relationships between the measures under investigation. A longitudinal study of a representative sample of 184 children with ambulant CP was conducted (112 males, 72 females; 94 had unilateral spastic C P, 84 had bilateral spastic C P, and six had non-spastic forms; age range 4-17y; Gross Motor Function Classification System Level I, n=57; Level II, n=91; Level III, n=22; and Level IV, n=14); energy efficiency (oxygen cost) during gait, activity limitation, participation restriction, and health status were recorded. Energy efficiency during gait was shown to correlate significantly with activity limitations; no relationship between energy efficiency during gait was found with either participation restriction or health status. With the exception of psychosocial health, all other measures showed significant differences by clinical subtype and gross motor classification. The energy efficiency of walking is not reflective of participation restriction or health status. Thus, therapies leading to improved energy efficiency may not necessarily lead to improved participation or general health. [source] Quality of life and health-related quality of life of adolescents with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 7 2007Peter L Rosenbaum MD FRCP(C) This study assessed quality of life (QOL) and health-related quality of life (HRQOL) of 203 adolescents with cerebral palsy (111 males, 92 females; mean age 16y [SD 1y 9mo]). Participants were classified using the Gross Motor Function Classification System (GMFCS), as Level I (n=60), Level II (n=33), Level III (n=28), Level IV (n=50), or Level V (n=32). QOL was assessed by self (66.5%) or by proxy (33.5%) with the Quality of Life Instrument for People With Developmental Disabilities, which asks about the importance and satisfaction associated with the QOL domains of Being, Belonging, and Becoming; HRQOL was captured through proxy reports with the Health Utilities Index, Mark 3 (HUI3), which characterizes health in terms of eight attributes, each having five or six ordered levels of function. GMFCS level was not a source of variation for QOL domain scores but was significantly associated with the eight HRQOL attributes and overall HUI3 utility scores (p<0.05). Some QOL domain scores varied significantly by type of respondent (self vs proxy; p<0.05). Overall HUI3 utility values were significantly but weakly correlated with QOL Instrument scores for Being (r=0.37), Belonging (r=0.17), Becoming (r=0.20), and Overall QOL (r=0.28), and thus explain up to 14% of the variance (r2). These findings suggest that although QOL and HRQOL are somewhat related conceptually, they are different constructs and need to be considered as separate dimensions of the lives of people with functional limitations. [source] The use of tiagabine in pediatric spasticity managementDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 6 2006Mary Lynn Chu MD Tiagabine, developed as an anti-epileptic medication, has the potential to reduce spasticity. The purpose of the present study was to assess the effectiveness of tiagabine in decreasing spasticity and improving the functional abilities of children with spastic cerebral palsy (CP). Nine children (seven females, two males) with CP (six spastic quadriplegia, three moderate to severe spastic diplegia) were treated with tiagabine for a mean of 7.2 months. Median age was 4y 5mo (range 3y 2mo-10y). All children were non-ambulatory. According to the Gross Motor Function Classification System, six were Level IV and three were Level V. Only one child showed a median decrease ,1.0 grade on the modified Ashworth scale in upper extremities, lower extremities, and overall. Another child had significant improvement in the Pediatric Evaluation of Disability Inventory Self-care score and improved feeding. None of the participants was found to have a significant improvement in motor function or a decrease in the number of motions (passive range of motion and muscle length test) that were limited. Reduction of nocturnal awakenings from painful spasms was reported in one child. Eight of the nine children experienced adverse side-effects during treatment. Although tiagabine was not found to be effective in decreasing children's spasticity or improving their function, its potential use in the relief of painful spasms associated with neurological conditions in the pediatric population warrants further investigation. [source] The distribution of lymph node metastases in supraglottic squamous cell carcinoma: Therapeutic implicationsHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002Luca O. Redaelli de Zinis MD Abstract Background. The treatment of the neck in cancer of the upper aerodigestive tract is still a matter of controversy, even though nowadays there is a trend in the literature toward elective surgery in the N0 neck when the probability of occult lymph node metastasis is greater than 20%. In the elective setup, every effort is made for preservation of uninvolved nonlymphatic structures in positive neck. The aim of this study is to analyze in a large cohort of patients treated for supraglottic carcinoma the prevalence of lymph node metastases and their distribution through various neck levels to redefine our policy of neck treatment. Methods. A retrospective review of 402 consecutive patients, who underwent surgery in the Department of Otolaryngology of the University of Brescia (Italy) for supraglottic squamous cell carcinoma in a 14-year period, has been performed. The prevalence of neck metastases was assessed by pT category and site (marginal vs vestibular) of the primary tumor. The side(s) of neck disease was related to the side of the primary tumor, whether lateral or central. The distribution of involved lymph nodes through the neck levels was determined. Results. Overall lymph node metastases accounted for 40%; their prevalence rate increased with pT category from 10% to 57% (p = .0001). Occult metastases were found in 26% of N0 patients from 0% in pT1 to 40% in pT4 (p = .02). There was no difference in metastases rate between marginal vs vestibular, and central vs lateral neoplasms, whereas bilateral metastases were more frequent in central tumors (20% vs 5%; p < .0001). Level IV was involved only in association with level II and/or level III. Levels I and V were rarely involved when overt metastases were present and never by occult metastases. Conclusions. Elective lateral neck dissection (levels II,IV) is recommended in T2,T4 N0 supraglottic cancers; clearance of both sides of the neck is indicated whenever the lesion is not strictly lateral. We still perform a selective neck dissection including levels II,V whenever there is clinical, radiologic, or intraoperative evidence of metastases at any level. © 2002 Wiley Periodicals, Inc.

Methods: A double-blind, randomised cross-over pilot study of oral baclofen versus placebo. Assessment tools included the Goal Attainment Scale, Pediatric Evaluation of Disability Inventory, Modified Tardieu Scale and parent questionnaire. Results: Fifteen children with mean age 7.4 years (SD = 2.7 years) and spastic or spastic/dystonic quadriplegia (Gross Motor Function Classification System Level IV or V) were enrolled. Children scored significantly better on the Goal Attainment Scale with baclofen compared with placebo (F(1,13) = 4.5, P = 0.05). There was no significant difference between baclofen and placebo for the Pediatric Evaluation of Disability Inventory or Modified Tardieu Scale. Parent questionnaire results are described. Conclusion: This pilot study demonstrates that oral baclofen has an effect beyond placebo in improving goal-oriented tasks, such as transfers, in children with spastic quadriplegic cerebral palsy. [source] Phase I trial of weekly docetaxel and gemcitabine in patients with refractory malignanciesCANCER, Issue 1 2003M.Sc., Tarek Mekhail M.D. Abstract BACKGROUND A Phase I study using weekly docetaxel and gemcitabine was conducted to investigate toxicity; to determine the maximum tolerated dose (MTD) of each agent; and, in a preliminary fashion, to determine the antitumor activity of the combination. METHODS Docetaxel and gemcitabine were administered intravenously on Days 1, 8, and 15 every 28 days. The dose levels of docetaxel and gemcitabine were as follows: Level I, docetaxel 20 mg/m2and gemcitabine 400 mg/m2; Level II, docetaxel 30 mg/m2and gemcitabine 400 mg/m2; Level III, docetaxel 30 mg/m2and gemcitabine 600 mg/m2; Level IV, docetaxel 36 mg/m2and gemcitabine 600 mg/m2; and Level V, docetaxel 36 mg/m2and gemcitabine 800 mg/m2. RESULTS Thirty-three eligible patients were entered. The diagnoses were as follows: Eleven patients had nonsmall cell lung carcinoma, 3 patients had carcinoma of the bladder, 3 patients had renal carcinoma, 2 patients had adrenal carcinoma, 5 patients had unknown primary tumors, and 9 patients had miscellaneous malignancies. Fifty-nine percent of patients had received prior chemotherapy. The median age was 62 years (range, 27,77 years), and the median Eastern Cooperative Oncology Group performance status was 1 (range, 0,1). Five patients were treated at Dose Levels I and II, 6 patients were treated at Dose Levels III and V, and 11 patients were treated at Dose Level IV. Grade 3,4 toxicities during Cycle I included neutropenia, thrombocytopenia, mucositis, and diarrhea. Dose-limiting toxicity, consisting of neutropenia and thrombocytopenia, occurred in three of six patients at Dose Level V. The combination of docetaxel 36 mg/m2 and gemcitabine 600 mg/m2 (Dose Level IV) was determined as the MTD and was the recommended Phase II dose. Two patients had a partial response: one patient with bladder carcinoma (Dose Level II) and one patient with nonsmall cell lung carcinoma (Dose Level III). CONCLUSIONS Overall, weekly docetaxel and gemcitabine were well tolerated. Further studies using this combination are planned, including a Phase II trial in patients with advanced nonsmall cell lung carcinoma. Cancer 2003;97:170,8. © 2003 American Cancer Society.

Background., Cerebral palsy is the commonest cause of motor impairment in childhood and is associated with life-long disability. An estimated 30% of people with cerebral palsy have severe forms and are non-ambulant. Although the underlying neurological damage is not amenable to correction, many health services are dedicated to providing therapeutic and adaptive support to help people with the condition reach their potential. Method., A cross-sectional survey of children and young people, aged 4,25 years with severe, non-ambulant cerebral palsy as defined using the Gross Motor Function Classification System (Levels IV and V). Study participants will be identified from a pre-existing, geographically defined case register and recruited via a healthcare professional known to them. Two assessments will be undertaken: one involving parents/carers at home and using questionnaires; the other involving the child/young person ideally in one of three settings and including X-rays if clinically indicated. Discussion., This study will contribute to our knowledge of the history and epidemiology of orthopaedic problems in children and young people with cerebral palsy and how these problems accumulate and impact on participation, health and well-being. The study will also identify unmet need and make recommendations for good practice in relation to the orthopaedic care and management for people with severe cerebral palsy. [source] Social functioning and communication in children with cerebral palsy: association with disease characteristics and personal and environmental factorsDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 5 2010JEANINE M VOORMAN Aim, The objective of this longitudinal study was to describe the course of social functioning and communication in children with cerebral palsy (CP) over a 3-year period, its difference with the normative course, and its relationship with disease characteristics and personal and environmental factors. Method, Participants in this study were 110 children with CP (70 males, 40 females) with a mean age of 11 years and 3 months (SD 1y 8mo). Social functioning and communication were measured with the Vineland Adaptive Behavior Scales. Comparisons were made with normative data; data were analysed with generalized estimating equations. According to the Gross Motor Function Classification System (GMFCS), 50 of the 110 children were categorized as GMFCS level I, 16 as level II, 13 as level III, 13 as level IV, and 18 as level V. Results, The course of social functioning over a 3-year period showed an increase in restrictions in children with CP (p<0.001). Restrictions in communication increased more in children with the most severe forms of CP (p<0.001). In addition to disease characteristics (GMFCS category, presence of epilepsy, and speech problems), personal factors (externalizing behaviour problems) and environmental factors (having no siblings, low parental level of education, and parental stress) were associated with greater restrictions in social functioning and communication. Interpretation, The results indicate that it is important to focus not only on the medical treatment of children with CP, but also on their behavioural problems and social circumstances, and to support the parents so that social functioning and communication in these children may be improved. [source] Cerebral palsy in siblings caused by compound heterozygous mutations in the gene encoding protein CDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 5 2010CHOONG YI FONG We report two sisters with extensive bilateral periventricular haemorrhagic infarction (PVHI) causing cerebral palsy (CP). The older sister presented at 20 months with cortical visual blindness, spastic diplegia, and purpura fulminans. The younger sister presented aged 3 days old with apnoeas and multifocal seizures. She subsequently had global developmental delay, cortical visual blindness, spastic quadriplegia, epilepsy, and purpura fulminans at age 2 years. Neuroimaging of both siblings showed bilateral PVHI consistent with bilateral cerebral intramedullary venous thrombosis occurring at under 28 weeks' gestation for the older sister and around time of birth for the younger sister. At latest follow-up, the older sister (13y) has spastic diplegia at Gross Motor Function Classification System (GMFCS) level II, and the younger sister (10y) has spastic quadriplegia at GMFCS level IV. Both sisters showed partial quantitative reduction in plasma protein C antigen and severe qualitative reduction in plasma protein C anticoagulant activity. They were heterozygous for two independent mutations in the protein C gene (PROC). There was no other risk factor for CP. To our knowledge, this is the first family reported with compound heterozygous PROC mutations as the likely genetic cause of familial CP. This report adds to the list of known monogenic causes of CP. [source] Systemic adverse events following botulinum toxin A therapy in children with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2 2010KRISHANT NAIDU Aim, We studied the incidence of incontinence and respiratory events in children with cerebral palsy who received injections of botulinum toxin A (BoNT-A). Method, We used multivariable logistic regression to investigate relationships between (BoNT-A) dose, Gross Motor Function Classification System (GMFCS) level, and the incidence of bladder or bowel incontinence, unplanned hospital admission, emergency department consultation or prescription of antibiotics for respiratory symptoms, and diagnosis of upper respiratory tract infection. Results, Of 1980 injection episodes in 1147 children (mean age 4y 7mo, SD 1y 10mo, range 9mo,23y), 488 (25%) were in children with unilateral involvement and 1492 (75%) in children with bilateral involvement. At the time of injection 440 (22.2%) of children were at GMFCS level I, 611 (30.9%) were at level II, 330 (16.7%) were at level III, 349 (17.6%) were at level IV, and 250 (12.6%) were at level V. The incidence of serious adverse events was low, with 19 episodes of incontinence (1% of injection episodes) and 25 unplanned hospital admissions due to respiratory symptoms (1.3%). Incontinence typically resolved spontaneously 1 to 6 weeks after injection. The incidence of adverse events was associated with GMFCS level and dose of BoNT-A. Interpretation, The incidence of serious adverse events was low but suggests systemic spread as well as a procedural effect. We recommend reviewing upper dose limits for children at all GMFCS levels, particularly those at levels IV and V with a history of aspiration and respiratory disease. In these children, alternatives to mask anaesthesia may be particularly important. [source] Probability of walking, wheeled mobility, and assisted mobility in children and adolescents with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 1 2010ROBERT J PALISANO Aim, Our aim was to describe how the probability of walking, wheeled mobility, and assisted mobility changes with environmental setting and age in children and adolescents with cerebral palsy (CP). Method, The parents of a population-based sample of 642 children and adolescents (360 males, 282 females; age range 16mo,21y) reported their children's mobility at home, school, and outdoors at 6- or 12-month intervals a mean of 5.2 times. Generalized mixed-effects analyses were used to model the probabilities. Results, By age 3 years, children with motor function classified as level I according to the Gross Motor Function Classification System (GMFCS) walked in all three settings. Children/adolescents classified as level V used assisted mobility, with a small number using wheeled mobility. In the case of children classified as GMFCS level II, the probability of walking varied with the environmental setting, which, at age 18, is outdoors 90% of the time. Among children classified as GMFCS level III, the probability of walking was highest at age 9 at school (68%), and at age 18 was approximately 50% in all three settings. Among children/adolescents rated as GMFCS level IV, the probability of wheeled mobility increased with age and, at age 18, 57% of mobility took place outdoors. Interpretation, The results provide evidence that age and environmental setting influence method of mobility of children/adolescents with CP. The method that is preferred in one setting may not be preferred in another setting or at another age. [source] Early motor repertoire is related to level of self-mobility in children with cerebral palsy at school ageDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 11 2009JANNEKE LM BRUGGINK MD Aim, To determine the predictive value of the early motor repertoire for the level of self-mobility in children with cerebral palsy (CP) at school age. Method, Video recordings were made at 11 to 17 weeks post-term of 37 preterm infants (20 males, 17 females) who later developed CP. The early motor repertoire was assessed by obtaining a motor optimality score. At 6 to 12 years, children were classified according to the Gross Motor Function Classification System (GMFCS). Results, Of 37 children (mean gestational age 29.1wks, SD 1.9; mean birthweight 1273g, SD 324), nine had unilateral and 28 had bilateral spastic CP. Twelve children were in GMFCS level I, three level II, 10 level III, four level IV, and eight level V. The absence of the age-adequate motor repertoire, a cramped motor repertoire, an abnormal kicking pattern, and a non-flat supine posture were associated with lower levels of self-mobility (,2 for trend test, p<0.05). Predictive for a low level of self-mobility was a cramped motor repertoire/non-flat supine posture (positive predictive values [PPV] 100%, negative predictive values [NPV] 54%). Predictive for a high level of self-mobility was a non-cramped repertoire/flat supine posture (PPV 80%, NPV 74%). Interpretation, Several aspects of the motor repertoire at 11 to 17 weeks post-term predicted the degree of functional limitations in children with CP at school age. [source] Motor function in 5-year-old children with cerebral palsy in the South Australian populationDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 7 2009JAMES RICE The aim of this study was to describe the motor function of a population of children at age 5 years enrolled on the South Australian Cerebral Palsy Register. Among children born between 1993 and 1998, there were 333 with confirmed cerebral palsy (prevalence rate 2.2 per 1000 live births), in whom 247 assessments (56.7% males, 43.3% females) were completed. The distribution by Gross Motor Function Classification System (GMFCS) level was: level I, 50.6%; level II, 18.2%; level III, 9.3%; level IV, 9.7%; level V, 12.1%. The most common topographical classification was spastic diplegia (38.5%), followed by spastic hemiplegia (34.8%) and spastic quadriplegia (14.6%). Abnormal movements occurred at rest or with intention in 19.4% of children. A high proportion of the population with relatively mild gross motor impairments have difficulty with everyday bimanual tasks, reinforcing the need to assess upper limb function independently of gross motor function. The use of ankle,foot orthoses was common, particularly across GMFCS levels II to IV. Further refinement is indicated for this population's motor dataset, to include more recently described classification measures as well as future novel measures to better describe the presence of both spasticity and dystonia. [source] Ataxia, autism, and the cerebellum: a clinical study of 32 individuals with congenital ataxiaDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 3 2005Ingegerd Åhsgren MD The suggested link between autism and cerebellar dysfunction formed the background for a Swedish clinical study in 2001. Thirty-two children (17 females, 15 males; mean age 12y, SD 3y 10mo; range 6 to 21y) with a clinical suspicion of non-progressive congenital ataxia were examined, and parents were interviewed about the presence of neuropsychiatric problems in the child. Twelve children had simple ataxia, eight had ataxic diplegia, and 12 had,borderline'ataxia. All but one of the 32 children had a mild to moderate gross motor disability according to Gross Motor Function Classification System (15 were categorized as level I,16 as level II, and one child as level IV). Neuroimaging and neuropsychological testing were achieved in most cases. There was a strong association between learning disability* and autism spectrum disorder (often combined with hyperactivity disorder) on the one hand, and both simple and borderline,ataxia'on the other, but a weaker link between ataxic diplegia and neuropsychiatric disorders. A correlation between cerebellar macropathology on neuroimaging and neuropsychiatric disorders was not supported. Congenital ataxia might not be a clear-cut syndrome of cerebellar disease, but one of many signs of prenatal events or syndromes, leading to a complex neurodevelopmental disorder including autism and learning disability. [source] Predicting the pattern of regional metastases from cutaneous squamous cell carcinoma of the head and neck based on location of the primaryHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2010Ardalan Ebrahimi FRACS Abstract Background We aimed to analyze the distribution of regional nodal metastases according to primary tumor location in patients with cutaneous squamous cell carcinoma of the head and neck (SCCHN). Methods Analysis of 295 neck dissections performed for patients with clinically evident regional metastases from cutaneous SCCHN between 1987 and 2009. Results Level I involvement in the absence of level II or III only occurred in patients with facial primaries. In patients with clear nodes in level II,III, the risk of level IV,V involvement was 0.0% for external ear primaries, 2.7% for face and anterior scalp, and 15.8% for posterior scalp and neck. Conclusion In patients undergoing parotidectomy for metastatic cutaneous SCCHN with a clinically negative neck, the results of this study support selective neck dissection including level I,III for facial primaries, level II,III for anterior scalp and external ear primaries, and levels II,V for posterior scalp and neck primaries. © 2010 Wiley Periodicals, Inc. Head Neck, 2010 [source] Routine inclusion of level IV in neck dissection for squamous cell carcinoma of the larynx: Is it justified?HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 4 2004Avi Khafif MD Abstract Background. Dissection of levels II,IV as part of an elective or therapeutic neck dissection is common practice during laryngectomy for laryngeal squamous cell carcinoma (SCC). The necessity of routine dissection at level IV has recently been questioned. The purpose of this study was to find the incidence of level IV metastases in patients with transglottic and supraglottic SCC who underwent neck dissections. Methods. The charts of 71 suitable patients were reviewed. Forty-two had supraglottic primary cancers, and 29 had transglottic primary tumors. Levels II,IV had been removed in them all, and their neck specimens were marked according to the levels of the neck. The surgical specimens were pathologically diagnosed. Results. Of 43 patients who underwent elective lateral neck dissection, the only one (2.3%) with level IV metastases also showed metastases at level II. Nine (32%) of the other 28 patients with clinical adenopathy had level IV metastases. Conclusions. Dissection of level IV as part of a therapeutic neck dissection for supraglottic and transglottic SCC is recommended for patients with clinically enlarged lymph nodes, but its necessity in the absence of detectable adenopathy is challenged. © 2004 Wiley Periodicals, Inc. Head Neck26: 309,312, 2004 [source] Feasibility of supraomohyoid neck dissection in N1 and N2a oral cancer patientsHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002Luiz P. Kowalski MD Abstract Background The use of selective neck dissection in a positive neck is still controversial. The object of this study was to ascertain the possibility of doing this procedure in oral cavity carcinoma with a single clinically metastatic lymph node smaller than 6 cm (N1 and N2a). Patients and Methods From 1970 to 1994, we analyzed 164 oral cavity cancer patients with clinically N1 or N2a stage cancer submitted to radical neck dissection. Results The histologic findings did not confirm a metastatic lymph node in 69 (42.1%) cases (pN0) and showed multiple lymph nodes in 19 (11.6%) cases. Moreover, just one patient (0.6%) had a metastatic lymph node at level IV (one case with multiple lymph nodes) and none at level V. Conclusions Because we did not find a single metastatic lymph node at levels IV and V and there was a high incidence of pN0 (57.4%) in patients with clinical N1 stage at level I, these patients could be candidates for a supraomohyoid neck dissection (extended or not to level IV) instead of radical neck dissection. © 2002 Wiley Periodicals, Inc. [source] Clinical outcome of surgical management for patients with renal cell carcinoma involving the inferior vena cavaINTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2007Tomoaki Terakawa Background: The objective of this study was to evaluate the clinical outcome after surgical management of renal cell carcinoma (RCC) extending to the inferior vena cava (IVC). Methods: This study included a total of 55 patients (41 men and 14 women; mean age, 59.3 years) with RCC (39 right- and 16 left-sided tumors) involving the IVC, who underwent radical nephrectomy and tumor thrombectomy between 1983 and 2005 at a single institution in Japan. The level of thrombus was classified as follows: level I, infrahepatic; level II, intrahepatic; level III, suprahepatic; and level IV, extending to the atrium. Clinicopathological data from these patients were retrospectively reviewed to identify factors associated with survival. Results: There were 11 and 18 patients who were diagnosed as having lymph node and distant metastases, respectively. Twenty-two patients had tumor thrombus in level I, 20 in level II, 10 in level III, and 3 in level IV. Pathological examinations demonstrated that 34 and 21 patients had clear cell carcinoma and non-clear cell carcinoma, respectively, 42, 9 and 4 were pT3b, pT3c and pT4, respectively, and 6, 35 and 14 were Grades 1, 2 and 3, respectively. Cancer-specific 1-, 3- and 5-year survival rates of these 55 patients were 74.5%, 51.4% and 30.3%, respectively. Among several factors examined, clinical stage (P = 0.047), lymph node metastasis (P = 0.016), histological subtype (P = 0.034) and tumor grade (P < 0.001) were significantly associated with cancer-specific survival by univariate analysis. Furthermore, multivariate analysis demonstrated clinical stage (P = 0.037) and tumor grade (P < 0.001) as independent predictors of cancer-specific survival irrespective of other significant factors identified by univariate analysis. Conclusions: In patients with RCC involving the IVC, biological aggressiveness characterized by tumor grade rather than tumor extension would have more potential prognostic importance; therefore, more intensive multimodal therapy should be considered in patients with high grade RCC with tumor thrombus extending into the IVC. [source] Sentinel lymph node biopsy in patients with thin melanomasTHE JOURNAL OF DERMATOLOGY, Issue 8 2007Roberto CECCHI ABSTRACT The aim of the present study is to report our experience with lymphatic mapping (LM) and sentinel lymph node biopsy (SLNB) in a selected group of patients with thin primary cutaneous melanomas. Fifty patients (22 females and 28 males; mean age, 57.8 years; range, 30,77 years) with a mean tumor thickness of 0.63 mm (range, 0.24,1.00 mm) underwent LM/SLNB. Twenty-eight (56%) of them had Clark level II, 20 (40%) had Clark level III, and two (4%) had Clark level IV. Tumor ulceration was present in two patients (4%) and histological regression in 35 patients (70%). Sentinel lymph node (SLN) metastases occurred in two of 50 patients (4%). The first case was a 0.88-mm thick, Clark level III, non-ulcerated superficial spreading melanoma of the trunk, without any regression. The second case was a 0.95-mm thick, Clark level IV, non-ulcerated superficial spreading melanoma of the neck, with regression. Both patients were disease-free 76 and 50 months after the SLNB procedure and followed complete lymph node dissection, respectively. The patients with negative SLN were disease-free after a median follow up of 44 months (mean, 43.2; range, 15,84 months). Published data and our experience suggest that LM/SLNB is not routinely indicated for melanomas less than 0.75 mm. Our results confirmed the accuracy of the new American Joint Committee on Cancer/International Union Against Cancer criteria, in which SLNB is required for thin melanomas less than 1.0 mm when they have ulceration or Clark level IV and V invasion. [source] Distributions of Cervical Lymph Node Metastases in Oropharyngeal Carcinoma: Therapeutic Implications for the N0 NeckTHE LARYNGOSCOPE, Issue 7 2006Young Chang Lim MD Abstract Objectives: This study sought to investigate the patterns and distributions of lymph node metastases in oropharyngeal squamous cell carcinoma (SCC) and improve the rationale for elective treatment of N0 neck. Materials and Methods: One hundred four patients with oropharyngeal SCC who underwent neck dissection between 1992 and 2003 were analyzed retrospectively. All patients had curative surgery as their initial treatment for the primary tumor and neck. A total of 161 neck dissections on both sides of the neck were performed. Therapeutic dissections were done in 71 and 5 necks and elective neck dissection was done on 33 and 52 necks on the ipsilateral and contralateral sides, respectively. Surgical treatment was followed by postoperative radiotherapy for 78 patients. The follow-up period ranged from 1 to 96 months (mean, 30 months). Results: Of the 161 neck dissection specimens evaluated, 90 (56%) necks were found to have lymph node metastases found by pathologic examination. These consisted of 76 (73% of 104 necks) of the ipsilateral side and 14 (25% of 57 necks) of the contralateral side dissections. The occult metastatic rate was 24% (8 of 33) of ipsilateral neck samples and 21% (11 of 52) of contralateral neck samples. Of the 68 patients who had a therapeutic dissection on the ipsilateral side and had lymphatic metastasis, the incidence rate of level IV and level I metastasis was 37% (25 of 68) and 10% (7 of 68), respectively. Isolated metastasis to level IV occurred on the ipsilateral side in three patients. There were no cases of isolated ipsilateral level I pathologic involvement in an N-positive neck or occult metastasis to this group. The incidence rate of level IV metastasis in patients with ipsilateral nodal metastasis was significantly higher in base of tongue cancer (86% [6 of 7]) compared with tonsillar cancer (34% [20 of 59]) (P = .013). Patients with level IV metastasis had significantly worse 5-year disease-free survival rates than patients with metastasis to other neck levels (54% versus 71%; P = .04). Conclusion: These results suggest that elective N0 neck treatment in patients with oropharyngeal SCC, especially base of tongue cancer, should include neck levels II, III, and IV instead of levels I, II, and III. [source] Systemic adverse events following botulinum toxin A therapy in children with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2 2010KRISHANT NAIDU Aim, We studied the incidence of incontinence and respiratory events in children with cerebral palsy who received injections of botulinum toxin A (BoNT-A). Method, We used multivariable logistic regression to investigate relationships between (BoNT-A) dose, Gross Motor Function Classification System (GMFCS) level, and the incidence of bladder or bowel incontinence, unplanned hospital admission, emergency department consultation or prescription of antibiotics for respiratory symptoms, and diagnosis of upper respiratory tract infection. Results, Of 1980 injection episodes in 1147 children (mean age 4y 7mo, SD 1y 10mo, range 9mo,23y), 488 (25%) were in children with unilateral involvement and 1492 (75%) in children with bilateral involvement. At the time of injection 440 (22.2%) of children were at GMFCS level I, 611 (30.9%) were at level II, 330 (16.7%) were at level III, 349 (17.6%) were at level IV, and 250 (12.6%) were at level V. The incidence of serious adverse events was low, with 19 episodes of incontinence (1% of injection episodes) and 25 unplanned hospital admissions due to respiratory symptoms (1.3%). Incontinence typically resolved spontaneously 1 to 6 weeks after injection. The incidence of adverse events was associated with GMFCS level and dose of BoNT-A. Interpretation, The incidence of serious adverse events was low but suggests systemic spread as well as a procedural effect. We recommend reviewing upper dose limits for children at all GMFCS levels, particularly those at levels IV and V with a history of aspiration and respiratory disease. In these children, alternatives to mask anaesthesia may be particularly important. [source] Feasibility of supraomohyoid neck dissection in N1 and N2a oral cancer patientsHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002Luiz P. Kowalski MD Abstract Background The use of selective neck dissection in a positive neck is still controversial. The object of this study was to ascertain the possibility of doing this procedure in oral cavity carcinoma with a single clinically metastatic lymph node smaller than 6 cm (N1 and N2a). Patients and Methods From 1970 to 1994, we analyzed 164 oral cavity cancer patients with clinically N1 or N2a stage cancer submitted to radical neck dissection. Results The histologic findings did not confirm a metastatic lymph node in 69 (42.1%) cases (pN0) and showed multiple lymph nodes in 19 (11.6%) cases. Moreover, just one patient (0.6%) had a metastatic lymph node at level IV (one case with multiple lymph nodes) and none at level V. Conclusions Because we did not find a single metastatic lymph node at levels IV and V and there was a high incidence of pN0 (57.4%) in patients with clinical N1 stage at level I, these patients could be candidates for a supraomohyoid neck dissection (extended or not to level IV) instead of radical neck dissection. © 2002 Wiley Periodicals, Inc. [source] Cerebral palsy in southern Sweden II.ACTA PAEDIATRICA, Issue 11 2001Gross motor function, disabilities The gross motor function and disabilities in children with cerebral palsy in southern Sweden were investigated and related to clinical features. The study covered the birth year period 1990-1993 and comprised 167 children, 145 of them born in Sweden and 22 born abroad. The clinical features and gross motor function were analysed at a mean age of 6.8 y. Clinical features were obtained from a continuing healthcare follow-up programme. Gross motor function was classified according to the Gross Motor Function Classification System (GMFCS). Walking independently was possible for 86% of the hemiplegic, 63% of the pure ataxic, 61% of the diplegic and 21% of the dyskinetic children. None of the tetraplegic children was able to walk. The classification of gross motor function revealed that 59% of the children were categorized into levels I and II (mildly disabled), 14% into level III (moderately disabled) and 27% into levels IV and V (severely disabled). Children born abroad were more severely disabled. Conclusion: The standardized age-related classification system GMFCS enabled a specific description of gross motor function in relation to clinical features. Significant differences between GMFCS levels and subgroups of diagnosis, aetiology, intellectual capacity, epilepsy and visual impairment were found. [source] |
