[Ab] Abstract:A new species of treefrog of the Boophis rappiodes group (Anura, Mantellidae) is described from the Sahamalaza - Iles Radama National Park in northwest Madagascar. This new species is green in colour with bright red speckling across its head and dorsum; similar in morphology to other species of this group including: B. bottae, B. rappiodes, B. erythrodactylus and B. tasymena. The new species can be distinguished by its advertisement call and by a genetic divergence of more than 4.9% in the analysed mitochondrial 16S rRNA gene fragment. Its call consists of two note types: a trill and a click; although similar sounding to B. bottae, the trill note of the new species has a faster pulse rate while the click note is predominantly two-pulsed rather than three. All individuals were detected from the banks of two streams in Ankarafa Forest. The new species represents the only member of the B. rappiodes group endemic to Madagascar's western coast, with the majority of other members known from the eastern rainforest belt. Despite its conspicuous call, it has not been detected from other surveys of northwest Madagascar and it is likely to be a local endemic to the peninsula. The ranges of two other amphibian species also appear restricted to Sahamalaza, and so the area seems to support a high level of endemicity. Although occurring inside a National Park, this species is highly threatened by the continuing decline in the quality and extent of its habitat. Due to these threats it is proposed that this species should be classified as Critically Endangered according to the IUCN Red List criteria.

[Ab] Abstract:OBJECTIVE: To analyze the progression of asymptomatic osteonecrosis of the femoral head by evaluating its lesion size and location. METHODS: From January 2008 to June 2009, 24 cases or hips were available for outcome analysis. There were 16 males and 8 females with a mean age of 36.4 (22-46) years and a mean body mass index of 25.4 (17.5-35). The stages were Ia (n = 2), b (n = 4), IIa (n = 6), IIb (n = 8) and IIc (n = 4) according to ARCO staging system. The etiologies included corticosteroids (n = 16), alcohol abuse (n = 4) and idiopathic disease (n = 4). Magnetic resonance imaging (MRI) was used to measure lesion sizes with necrotic index method. And lesion locations were classified as medial, central and lateral. RESULTS: The mean follow-up period was 40.3 (32-60) months. Among 7 painful hips, there were corticosteroids (n = 5) and alcohol abuse (n = 2). And 5 hips (20.8%) collapsed. The mean interval between diagnosis and symptom was 40 (36-48) months. The lesion locations were lateral-central (n = 4) lateral-central-medial (n = 3). Significant difference existed between the average necrotic index of symptomatic and asymptomatic hips (45.4% vs 32.7%). CONCLUSION: There is a high risk of progression into symptomatic disease when the necrotic lesion occurs on the lateral and lateral-central or lateral-central-medial zone of the femoral head. Asymptomatic small and medially located lesions may be managed conservatively with close medical imaging observations.

[Ab] Abstract:OBJECTIVE: To explore the causes of emergency dizziness stratified to improve the diagnostic efficiency. METHODS: A total of 1 857 cases of dizziness at our emergency department were collected and their etiologies stratified by age and gender. RESULTS: The top three diagnoses were benign paroxysmal positional vertigo (BPPV, 31.7%), hypertension (24.0%) and posterior circulation ischemia (PCI, 20.5%). Stratified by age, the main causes of dizziness included BPPV (n = 6), migraine-associated vertigo (n = 2), unknown cause (n = 1) for the group of <18 years; BPPV (51.5%), migraine-associated vertigo (14.5%) and neurosis (7.3%) for 18-44 years; BPPV (36.8%), hypertension (22.4%) and migraine-associated vertigo (11.2%) for 45-59 years; hypertension (30.8%), PCI (29.8%) and BPPV (22.9%) for 60-74 years; PCI (30.7%), hypertension (28.6%) and BPPV (25.5%) for 75-92 years. BPPV, migraine and neurosis were more common in females while hypertension and PCI predominated in males (all P < 0.05). CONCLUSION: As the main causes of emergency dizziness, BPPV, PCI, hypertension, neurosis and migraine showed the following significant demographic features: BPPV, PCI, hypertension, neurosis and migraine may be the main causes of dizziness. BPPV should be considered initially when vertigo was triggered repeatedly by positional change, especially for young and middle-aged women. And the other common causes of dizziness were migraine-associated vertigo, neurosis and Meniere's disease.Hypertension should be screened firstly in middle-aged and elderly patients presenting mainly with head heaviness and stretching. In elders with dizziness, BPPV is second in constituent ratio to PCI and hypertension.In middle-aged and elderly patients with dizziness, psychological factors should be considered and diagnosis and treatment should be offered timely.

[Ab] Abstract:Head trauma accounts for a significant number of injuries in the wilderness setting. Concussions are possible sequelae of falls or encounters with unforeseen obstacles. Although not immediately life-threatening, concussions can be a source of significant short- and long-term morbidity. Diagnosis of a concussion in the wilderness may be challenging as symptoms can often be confused with other conditions, such as altitude illness and hyponatremia. Successful management depends on accurate diagnosis and determination of the severity of symptoms so that appropriate decisions regarding treatment and need for evacuation can be made.

[Ti] Title:Management of the hemiplegic shoulder complex.

[Ab] Abstract:Hemiplegia in the upper limb and shoulder complex is a common secondary impairment resulting from a cerebrovascular event; evidence-based intervention is required for effective treatment. Prior to addressing shoulder movement, biomechanical alignment of the pelvis and trunk must first be assessed. Extreme care must be taken when completing passive range of motion with the hemiplegic shoulder; motion should not exceed beyond 90° of shoulder flexion and abduction without scapular upward rotation and humeral head external rotation. It is recommended that the use of slings with upper limb hemiplegia be limited. A subluxation of the shoulder can be treated with surface neuromuscular electrical stimulation if the recommended protocol of 6 hours daily, 5 days a week, for 6 weeks is utilized. Taping/strapping for a subluxation has conflicting evidence for reducing the development of hemiplegic shoulder pain, and it does not improve upper limb function or range of motion.

[Ab] Abstract:BACKGROUND: Since 2003, very few publications have described brain examinations using neonatal MR-compatible incubator (INC). The authors present their first experience in these examinations, not limited to brain scans, with the use of an incubator equipped not only with head coil, but also with a coil designed for examinations of the spinal canal and spinal cord as well as the whole body, at the Institute of Mother and Child in Warsaw. MATERIAL/METHODS: Examinations were performed in 27 newborns (12 girls, 15 boys). Most of the neonates were prematurely born: 19 (70.4%) were born at gestational age of 23-37 weeks, mean of 30 weeks. They were examined at the corrected age of 26 weeks-1 month, mean of 36 weeks. Body weight of the newborns on the day of the study was 600-4,300 g, mean of 2,654 g. The study was performed with a GE Signa HDxT 1.5 T system with the use of a Nomag IC 1.5 incubator by Lammers Medical Technology Co., equipped with three coils: an eight-channel, phased-array head coil and a twelve-channel phased-array coil for the whole body, consisting of an eight-channel coil integrated in the incubator and a separate four-channel surface coil. RESULTS: Of the 27 children, 25 (92.6%) required a brain scan. Two children (7.4%) were referred to MRI for assessment of the spinal canal and the abdomen. We compared the results of transfontanelle ultrasound and MRI scans in 21 children. MRI provided significantly more diagnostic information in 18 cases (85.7%); in 3 cases (14.3%), no additional knowledge about the pathology was provided by the exam. CONCLUSIONS: The MR-compatible incubator increases the availability of MRI to newborns, especially premature newborns and those with low and extremely low body weight, for whom MR examinations are necessary to determine the extent of changes, not limited to the central nervous system, as well as to establish prognosis. Dedicated neonatal coils integrated with the incubator permit more accurate diagnosis than the previously used adult coils.

[Ab] Abstract:OBJECTIVE: To comparatively evaluate condylar surface bone formation and cortical thickening in patients with temporomandibular joint osteoarthritis, with or without stabilization splint (SS) therapy. STUDY DESIGN: This retrospective study of 57 OA patients included 18 patients who had undergone SS therapy (SS group), compared with 39 patients that had not received SS therapy (non-SS group). To evaluate osseous changes on the condylar bone formation and cortical thickening, pre- and post-treatment cone beam computed tomography images of each patient were superimposed using voxel registration. RESULTS: The SS group exhibited a higher ratio of bone formation in the anterior division of the condyle; the non-SS group exhibited mostly no change. The SS group was found to have higher frequencies of cortical thickening in the anteromedial, anterior-intermediate, anterolateral, posteromedial, and posterior-intermediate sections than the non-SS group. CONCLUSIONS: SS therapy in temporomandibular joint osteoarthritis induced favorable bone remodeling in the anterior division of the condylar head.

[Ab] Abstract:OBJECTIVE: The objectives of this study were to assess the organ and effective doses (International Commission on Radiological Protection [ICRP] 103 standard) resulting from supine, prone, and oblique phantom positions in the maxillofacial region using a novel cone beam computed tomography (CBCT) device and to compare the results with conventional dental CBCT and multislice computed tomography (MSCT) devices. STUDY DESIGN: Measurements were performed using an anthropomorphic RANDO head phantom (Radiation Analogue Dosimetry System) with 20 MOSFET (metal-oxide-semiconductor field-effect transistor) dosimeters placed in the most radiosensitive maxillofacial organs. Effective doses were measured in 3 phantom positions using a combined extremity and maxillofacial CBCT device: the Planmed Verity CBCT scanner. Reference values were measured in the upright position with 2 CBCT devices and in the prone position with one MSCT scanner. RESULTS: The Planmed Verity CBCT scanner effective doses were 247 µSv in supine, 192 µSv in prone, and 134 µSv in oblique position. The effective dose with ProMax 3D MAX CBCT was 168 µSv; with i-CAT Next Generation, 170 µSv; and with Philips Brilliance 64 MSCT, 781 µSv. CONCLUSIONS: Head positioning has an important effect on the organ and effective doses. The Planmed Verity CBCT scanner effective dose results were comparable with those attained on 2 conventional CBCT devices and were considerably lower than the MSCT scanner results.

[Ab] Abstract:OBJECTIVE: The aim of this study was to assess the prognostic value of residual node involvement after induction chemotherapy (ICT) for head and neck squamous cell carcinoma and to investigate post-ICT node status associated with tumor characteristics. STUDY DESIGN: We retrospectively analyzed a cohort of 109 patients with operable oral squamous cell carcinoma who underwent ICT followed by surgery with neck dissection. The median follow-up was 45 months. The primary endpoints were overall survival (OS) and disease-free survival (DFS). RESULTS: After ICT, 48 patients (44.0%) had no positive nodes, 46 (42.2%) had 1 to 3 residual nodes, and 15 (13.7%) had more than 3 residual nodes. The number of residual nodes was significantly associated with OS and DFS. On multivariate analysis, the number of residual nodes was an independent prognostic factor (P = .011 for DFS and P = .034 for OS). CONCLUSIONS: Although constituting a different parameter from primary surgery data, the number of positive nodes could remain a prognostic factor even after ICT (at secondary surgery).

[Ab] Abstract:OBJECTIVE: Extracranial vascular injuries of the head and neck are relatively underdiagnosed in patients with acute trauma and can carry devastating sequelae. We wished to identify the correlation between mandibular fractures and injuries to major vessels of the head and neck. STUDY DESIGN: A retrospective review of our trauma registry was performed for the 1993-2007 period. The data on all mandibular fractures were collected. RESULTS: A total of 2288 patients presented to Parkland Memorial Hospital with mandibular fractures, of whom 47 (2%) had an injury to a major vessel of the neck. Nearly half, 23 (48.9%), were the result of high-velocity penetrating injuries, namely gunshot wounds, whereas 17 (36.2%) were the result of high-velocity blunt motor vehicle or motorcycle collisions. CONCLUSIONS: Patients who sustain a mandibular fracture in the setting of a high-velocity mechanism should be approached with the possibility of vascular injury of the great vessels of the neck kept in mind.
