Specialty Registrars’ Experience of Managing Head and Neck Cancer Patients

Objective The aim of this study was to collate and compare data on the training of Specialty Registrars in Restorative Dentistry (StRs) in the management of head and neck cancer (HANC) patients across different training units within the UK and Ireland. Methods Current trainees were invited to complete an online questionnaire by the Specialty Registrars in Restorative Dentistry Group (SRRDG). Participants were asked to rate their confidence and experience of assessing and planning treatment for HANC patients, attending theatre alone and manufacturing surgical obturators, and providing implants for appropriate cases. Respondents were also asked to appraise clinical and didactic teaching at their unit, and to rate their confidence of passing a future Intercollegiate Specialty Fellowship Examination (ISFE)-station assessing knowledge of head and neck cancer. Results Responses were obtained from 21 StRs (n=21) training within all five countries of the British Isles. Most respondents were based in England (76%), with one StR in each of Scotland, Wales, Northern Ireland and the Republic of Ireland. A third (33%) were in their 5th year of training. Almost half of the StRs indicated that they were confident of independently assessing (48%) new patients with HANC, with fewer numbers reporting confidence in treatment planning (38%). The majority (52%) of respondents indicated that they were not confident of attending theatre alone and manufacturing a surgical obturator. A third (33%) rated their experience of treating HANC patients with implants as ‘poor’ or ‘very poor’, including three StRs in their 5th year of training. Less than one third (<33%) rated didactic teaching in maxillofacial prosthodontics at their unit as ‘good’ or ‘excellent’, and only 7 StRs indicated that they were confident of passing an ISFE-station focused on HANC. Conclusion Experience and training regarding patients with head and neck cancer is inconsistent for StRs across the UK and Ireland with a number of trainees reporting a lack of clinical exposure.

Affective Instability, Childhood Trauma and Major Affective Disorders

BACKGROUND: Affective instability (AI), childhood trauma, and mental illness are linked, but evidence in affective disorders is limited, despite both AI and childhood trauma being associated with poorer outcomes. Aims were to compare AI levels in bipolar disorder I (BPI) and II (BPII), and major depressive disorder recurrent (MDDR), and to examine the association of AI and childhood trauma within each diagnostic group. METHODS: AI, measured using the Affective Lability Scale (ALS), was compared between people with DSM-IV BPI (n=923), BPII (n=363) and MDDR (n=207) accounting for confounders and current mood. Regression modelling was used to examine the association between AI and childhood traumas in each diagnostic group. RESULTS: ALS scores in descending order were BPII, BPI, MDDR, and differences between groups were significant (p<0.05). Within the BPI group any childhood abuse (p=0.021), childhood physical abuse (p=0.003) and the death of a close friend in childhood (p=0.002) were significantly associated with higher ALS score but no association was found between childhood trauma and AI in BPII and MDDR. LIMITATIONS: The ALS is a self-report scale and is subject to retrospective recall bias. CONCLUSIONS: AI is an important dimension in bipolar disorder independent of current mood state. There is a strong link between childhood traumatic events and AI levels in BPI and this may be one way in which exposure and disorder are linked. Clinical interventions targeting AI in people who have suffered significant childhood trauma could potentially change the clinical course of bipolar disorder.

SAR determination and influence of the human head in the radiation of a mobile antenna for two different frequencies

The big proliferation of mobile communication systems has caused an increased concern about the interaction between the human body and the antennas of mobile handsets. In order to study the problem, a multiband antenna was designed, fabricated and measured to operate over two frequency sub bands 900 and 1800 MHz. After that, we simulated the same antenna, but now, in the presence of a human head model to analyze the head's influence. First, the influence of the human head on the radiation efficiency of the antenna has been investigated as a function of the distance between the head and the antenna and with the inclination of the antenna. Furthermore, the relative amount of the electromagnetic power absorbed in the head has been obtained.

A Memória e o Impacto do Trauma: Numa Perspectiva Desenvolvimental

Pretende-se realizar uma revisão sobre as estruturas neuroanatómicas e os processos de neurotransmissão e de modulação neuronal envolvidos na memória. A memória é vista como um processo activo, baseado na reunião de variados aspectos dos padrões de activação neuronal, num processo dependente da experiência. Descreve-se a importância das regiões límbicas e sua inter-relação no processamento da memória, desde a codificação até à consolidação que implica uma reestruturação neuronal. Procede-se à caracterização dos tipos de memória (implícita e explícita) e suas características,a relação com as diferentes fases do desenvolvimento, tocando alguns aspectos mais descritivos de diferentes componentes da memória. Numa perspectiva contextual são também focadas as áreas da amnésia infantil, a lembrança, o esquecimento e o trauma. O esquecimento é parte essencial da memória explícita. Vários estudos apontam para um efeito de curva em U invertida, em relação com o impacto emocional. Eventos com intensidade moderada a elevada parecem ser etiquetados como importantes (envolvimento de estruturas do sistema límbico como a amígdala e o córtex orbito-frontal) e são mais facilmente recordadas no futuro. Se os eventos são muitos intensos o processamento no hipocampo da codificação memoria explícita e subsequentemente a recordação são inibidos,há também um bloqueio da consolidação cortical da experiência, porém mantém-se a memória implícita, que pode levar a vivência de imagens intrusivas não elaboradas. No que concerne ao trauma, levanta-se a questão da precisão da memória e do seu impacto, tanto ao nível das implicações neurofisiológicas como das consequências psicopatológicas. As alterações ao nível das neurotransmissões induzidas pelo stress vão condicionar alterações na mielinização, sinaptogénese e neurogénese, que podem levar a alterações a longo prazo em várias regiões do cérebro entre as quais a amígdala. Nestas condições, o processo explícito e a aprendizagem podem ser cronicamente impedidas, para além do risco importante para o desenvolvimento de psicopatologia, nomeadamente: Perturbação da Personalidade, Perturbações de Humor (depressão); Perturbações de Ansiedade; Perturbações Dissociativas e maior risco de Psicose.

Abordagem ao Doente “ABCDE”. Biomecânica do Trauma

Apresentação na qual é efectuada uma caracterização epidemiológica do Trauma comparando a distribuição bimodal vs trimodal assim como a causa e local de morte. De seguida são definidos cuidados emergentes a nível pré-hospitalar e as competências indispensáveis à práxis por parte do Enfermeiro. Por último reflectimos de que forma a abordagem e o assegurar do continuum de cuidados desde o pré-hospitalar à UCI (com passagem no SU) contribuem para a melhoria dos cuidados ao doente politraumatizado.
