Herpes zoster is a common disease, affecting up to 30% of the population in their lifetime. We examined the burden of this disease over the period of 1997-2013 using administrative healthcare data to determine changes over time. Key medications used to treat herpes zoster and postherpetic neuralgia became generic, resulting in costs reductions, where was offset by increased drug utilization leaving drug-episode costs unchanged. Mean per-episode medical costs increased moderately. Combined, these resulted in increased outpatient costs over time. However, dramatic reduction in HZ-related hospitalizations countered these trends, resulting in no net change in overall burden. The total healthcare cost of treating HZ and PHN in Manitoba in 2011/12 was $1,997,183, slightly less than the $2,095,633 burden determined for 1997/98, the first study year. Long-term demographic projections suggest the population will continue to grow and age, likely driving the future burden upwards. / October 2016

A neuralgia pós-herpética é uma complicação da infecção pelo vírus da varicela zoster (VVZ). O nervo trigêmeo é acometido em cerca de 20-25% dos casos. Este estudo transversal teve como objetivo avaliar a sensibilidade orofacial de doentes com NPH trigeminal e identificar as características odontológicas da amostra. Foram utilizados os seguintes instrumentos de avaliação: exame sensitivo padronizado da face (algiometria, testes de sensibilidade térmica e táctil), questionário RDC/TMD, eixo I e II, (critérios de diagnóstico em pesquisa) para o diagnóstico de disfunção mandibular (DTM), protocolo para avaliação de dor orofacial (EDOF-HC), questionário McGill para avaliação de dor, exame periodontal (índice de placa - IP, índice de sangramento - IS, índice de profundidade clínica de sondagem - PCS e índice de profundidade clínica de inserção - PCI), e o índice CPO-D (somatória do número de dentes cariados, perdidos em razão de cárie dentária e restaurados). Houve diferença significativa entre o lado ipsolateral e o contralateral aos testes de sensibilidade no V1 com frio (p=0,038), vonFrey (p=0,008), alfinete (p=0,022) e algiometria (p=0,001); no V2 com frio (p=0,034), calor (p=0,019) e alfinete (p=0,037) e no V3 com frio (p= 0,042) e calor (p= 0,036); e na região intra-oral com alfinete (p=0,021). Dos 19 pacientes avaliados, 63,2% eram desdentados totais, a média do CPO-D foi de 28,3, a média do índice de placa foi de 48,0 e a média do índice de sangramento foi de 31,6. Neste estudo, 21% dos doentes relataram lesão na cavidade oral como sinal inicial do Herpes zoster. Com relação à condição músculo-esquelética da face (RDC/TMD), 78,9% tinha dor miofascial à palpação. Como conclusão destaca-se alteração de sensibilidade ipsolateral, mesmo nos ramos onde não houve erupção do VVZ, hipoalgesia em V1 e na mucosa oral ipsolateral; saúde oral comprometida, dor miofascial mastigatória e anormalidade da ATM na maioria dos doentes. / Postherpetic neuralgia is a complication after a varicella-zoster virus infection (VZV), affecting the trigeminal nerve in about 15-25% of the cases. This transversal study had the objective to evaluate the orofacial sensitivity and odontological characteristics of patients with trigeminal postherpetic neuralgia. The instruments used were: mechanical, thermal and pain sensory test, RDC/TMD questionnaire axis I and II (research diagnostic criteria for temporomandibular disorders), EDOF-HC protocol (for orofacial pain), McGill´s questionnaire, periodontal form (plaque index, blending index, clinical insertion and clinical deep level measures, to evaluate the periodontal disease as well the activity of disease) and DMFT index (Add of the number of teeth decayed, lost because caries and restored). There was significant difference compared the affected and the opposite side for tests of sensitivity at V1 with cold (p=0.038), vonFrey (p=0.008), pinpricks (p=0.022) and algiometric (p=0.001); at V2 with cold (p=0.034), heat (p=0.019) and pinpricks (p=0.037) and at V3 with cold (p = 0.042) and heat (p = 0.036) and in the intra-oral region with pinpricks (p=0.021). 63.2 % was edentulous, the average of the DMFT was 28.3, the average of the plaque\'s index was 48 and the average of the blending index was 31.6. In this study, 21 % of the patients reported lesion in the oral cavity like initial sign of the Herpes zoster. 78.9 % had myofascial pain with palpation (RDC/TMD). The main conclusions were alteration of sensitivity in the ipsolateral, even in the branches wherethere were no eruptions of the VVZ, hypoalgesia at V1 and oral mucosa ipsolateral; poor oral heath, masticatory myofascial pain and abnormality of the TMJ in the majority of the patients.

Provoked Vestibulodynia (PVD) is a common form of chronic genital pain, affecting approximately 12% of premenopausal women. Even though knowledge of vulvodynia has been present in the medical field for many years, it was previously thought to be of psychogenic origin and has never been thoroughly investigated for the purpose of pain classification. When investigating any pain condition, one of the most important distinctions to make is whether or not the pain is neuropathic. Even though this possibility has never been investigated in women with PVD, some have claimed that PVD pain contains elements of neuropathy, even treating this pain with medication created for neuropathic pain conditions. The purpose of this study was to use standardized measures and determine whether PVD may have a neuropathic component. Women with PVD completed an online survey assessing various pain and psychosocial variables. Their responses were compared with those of pain-free controls and women experiencing an established neuropathic pain condition, post-herpetic neuralgia (PHN). Women with PVD scored above established cut-offs on measures of neuropathic pain (NP). Further, for some NP measures there was no difference in scores between PVD and PHN women. Women with PVD also had similar psychosocial profiles as those with PHN, although women with PHN reported poorer health-related quality of life. Interestingly, the number of NP symptoms did not predict pain/psychosocial disturbance, or vary as a function of pain duration or intensity. Overall, these results lend support to the argument that PVD is a chronic pain condition. Further, these results indicate that women with PVD likely experience some form of NP. These results add to the understanding and classification of PVD, justifying further investigation, for example, via psychophysical testing and functional magnetic resonance imaging. / Thesis (Master, Psychology) -- Queen's University, 2011-09-21 16:25:34.216
