Anti-neutrophil cytoplasmic antibody associated vasculitis of the brain and oral cavity: a case report.

We report a patient with a novel presentation of anti-neutrophil cytoplasmic antibody positive (ANCA+) vasculitis of the brain and oral mucosa. ANCA+ vasculitis of the brain is usually associated with pachymeningitis and hypophysitis, and there are no cases reported with simultaneous brain and oral mucosal involvement. A 35-year-old African Zambian man presented with headache and bleeding swollen gingiva. He was myeloperoxidase (MPO) antibody positive with cytoplasmic staining. His MRI showed stable small callosal, periventricular and subcortical white matter non-enhancing lesions, without change over 15 months-compatible with vasculitis. His gingival biopsy was consistent with vasculitis. His headache and oral lesions responded to oral corticosteroids and intravenous immunoglobulin which have induced clinical remission. Our patient expands the clinical syndrome of ANCA+ MPO+ C-type vasculitis of the central nervous system with headaches complicating cerebral vasculitis and oral mucosal involvement.

Metastatic epithelioid haemangioendothelioma masquerading as periodontal pathosis: a case report.

We present a non-healing lesion on the gingivae attached to the mandible that mimicked periodontal disease, and was refractory to local debridement and oral hygiene measures. Biopsy examination showed a metastatic epithelioid haemangioendothelioma. This rare vascular tumour is considered to be malignant and management is controversial, owing to the paucity of published data. Treatment was provided in a multi-disciplinary setting as a result of established pulmonary and musculoskeletal metastases. The patient opted for conservative management and close surveillance of the lesion, which continues to remain stable at the time of writing, nearly two years after the initial assessment.

Compliance of post-radiation therapy head and neck cancer patients with caries preventive protocols.

BACKGROUND: Caries prevention is paramount in safeguarding the life quality of head and neck cancer patients and is dependent on patient compliance with caries preventive protocols. The purpose of this study was to examine this compliance. METHODS: All records of patients referred to one public oral medicine clinic servicing a head and neck oncology unit of one major Western Australian hospital, between January 2005 and December 2011, were examined. Data extracted included patient and cancer characteristics and compliance with dietary advice, dental care, oral hygiene instruction and fluoride use over a follow-up period of at least 12 months. Compliance was assessed against various oral health outcomes and patient characteristics. RESULTS: Of the 116 participants, 75.9% complied with all caries preventive measures over a mean follow-up period of 45 months. Non-compliance with regular dental attendance (P = 0.004), oral hygiene instruction (P = 0.009), dietary advice (P = 0.034) and daily fluoride use (P = 0.018) were associated with the development of dental caries post-treatment. The presence of dental caries at the time of cancer diagnosis was predictive of poorer compliance. CONCLUSIONS: High compliance with caries preventive measures is attainable in the head and neck cancer patient group. Factors other than fluoride use seem important in caries prevention.

Oral cavity squamous cell carcinoma - characteristics and survival in aboriginal and non-aboriginal Western australians.

BACKGROUND: Squamous cell carcinoma (SCC) is the most common type of malignancy affecting the oral cavity. While exposures to main risk factors for oral SCC such as smoking and alcohol use are higher amongst the Aboriginal people, little is known about oral cancer in this population. This study aimed to describe characteristics and survival of oral SCC in Aboriginal and non-Aboriginal Western Australians. METHODS: All primary oral SCC cases reported to the Western Australian Cancer Registry (WACR) between 1990 and 1999 were analysed with respect to person characteristics including: date of birth, sex and indigenous status; and disease characteristics including: date of biopsy, disease stage and site as well as date of recurrence and date of death. Exclusion criteria included diagnosis not based on incisional or excisional biopsy, diagnosis other than oral SCC or a history of another malignant neoplasm. RESULTS: Aboriginal individuals were more likely to reside in rural areas. No statistically significant differences in oral SCC characteristics and survival were noted between Aboriginal and non-Aboriginal Western Australians. CONCLUSION: This study provides new information on person and disease characteristics of Aboriginal Western Australians diagnosed with oral SCC.

Hyposalivation in a 16-year-old girl: a case of salivary gland aplasia.

Salivary gland aplasia is a rare condition with only a small number of cases reported worldwide. It is more commonly seen in males and can occur either in isolation or association with other defects or syndromes. It may or may not occur with a hereditary background. Scant literature exists detailing the status of sublingual salivary glands in patients with any form of major salivary gland aplasia. This case report describes the clinical and magnetic resonance imaging presentation of a 16-year-old girl with major salivary gland aplasia detailing the status of all six major salivary glands.

Dental attendance of oral and oropharyngeal cancer patients in a public hospital in Western Australia.

BACKGROUND: Dentists have recently seen the introduction of devices which aim to facilitate early oral cancer detection, sparking interest in opportunistic oral cancer screening. However, concerns have been raised about the lack of regular dental attendance amongst high risk individuals. The purpose of this study was to obtain information pertaining to dental attendance of oral and oropharyngeal cancer patients. METHODS: All records of patients referred to the Oral Medicine Clinic at the Oral Health Centre of Western Australia, between January 2005 and December 2009, from one major teaching hospital were examined. Information extracted included age, gender, smoking status, referral date, tumour type, tumour site, disease stage (TNM classification), and information on dental attendance. Outcomes measured included time (months) since the patient's last dental visit and information concerning regularity of dental attendance. RESULTS: No association was found between dental attendance and gender, smoking, disease stage or age at diagnosis. Most patients had not visited a dentist in the preceding 12 months. The mean date of last dental visit was 5.6 years prior. CONCLUSIONS: More should be done in Australia to encourage patients at high risk of oral cancer to attend the dentist and undergo annual oral soft tissue examination.

Knowledge and perceptions regarding oral and pharyngeal carcinoma among adult dental patients.

BACKGROUND: The aim of this study was to assess awareness and knowledge of oral and pharyngeal carcinoma and risk perception for developing the cancer among adult patients attending a major dental centre in Perth. Influence of socio-demographic factors on awareness, knowledge and perception was ascertained. METHODS: A random sample of 120 potential participants over the age of 18 who attended the Oral Health Centre of Western Australia between 14 and 18 June 2010 were invited to participate in the survey. A total of 100 participants completed a face-to-face interview guided by a questionnaire. RESULTS: Seventy-two per cent of the participants had heard of oral and pharyngeal carcinoma. Sixteen per cent knew that both smoking and drinking increased the risk of oral and pharyngeal carcinoma and 49% knew at least one sign or symptom of the cancer. Language spoken at home, education, and employment influenced cancer awareness and knowledge. Sixty-two per cent of the participants considered themselves not at risk of developing the cancer. CONCLUSIONS: The findings suggest that knowledge concerning oral and pharyngeal carcinoma in the community may be limited and educational strategies may be required to improve such knowledge.

Oral cavity squamous cell carcinoma survival by biopsy type: a cancer registry study.

BACKGROUND: Biopsy of a suspected oral squamous cell carcinoma (SCC) is important for diagnosis. Concerns have been raised about the potential for tumour spread by incisional biopsy techniques. This study aimed to investigate the five-year survival and recurrence of oral SCC after incisional and excisional biopsy in total population data available from the Western Australian Cancer Registry (WACR). METHODS: Total population data from the WACR, comprising all primary oral SCC cases diagnosed between 1990 and 1999, were examined. Information extracted included date of birth, gender, biopsy date, biopsy type, disease stage (TNM classification), disease site, date of recurrence and date of death. Records were excluded if the diagnosis was fine needle aspiration based, was not that of oral SCC and if a history was noted of another malignant neoplasm. Incisional and excisional biopsy cases were compared for five-year survival, adjusting for disease stage. RESULTS: No association was found between biopsy type and five-year survival or recurrence amongst individuals with Stage I or II disease. CONCLUSIONS: In this study, biopsy type was not associated with survival of oral SCC patients with Stage I or II disease, adding to the evidence that incisional biopsy of oral SCC can be a safe procedure.

Eating disorders and oral health: a review of the literature.

This article is a review of the recent literature pertaining to the oral sequelae of eating disorders (EDs). Dentists are recognized as being some of the first health care professionals to whom a previously undiagnosed eating disorder patient (EDP) may present. However, despite the prevalence (up to 4 per cent) of such conditions in teenage girls and young adult females, there is relatively little published in the recent literature regarding the oral sequelae of EDs. This compares unfavourably with the attention given recently in the dental literature to conditions such as diabetes mellitus, which have a similar prevalence in the adult population. The incidence of EDs is increasing and it would be expected that dentists who treat patients in the affected age groups would encounter more individuals exhibiting EDs. Most of the reports in the literature concentrate on the obvious clinical features of dental destruction (perimolysis), parotid swelling and biochemical abnormalities particularly related to salivary and pancreatic amylase. However, there is no consistency in explanation of the oral phenomena and epiphenomena seen in EDs. Many EDPs are nutritionally challenged; there is a relative lack of information pertaining to non-dental, oral lesions associated with nutritional deficiencies.

An investigation into the use of pilocarpine as a sialagogue in patients with radiation induced xerostomia.

BACKGROUND: Radiation therapy to the head and neck region can be an effective form of treatment for malignancies. Unfortunately damage to salivary glands may occur. Treatment of resultant dry mouth is at present very poor. The purpose of this pilot study was to investigate whether pilocarpine dissolved in artificial saliva and administered in a mouth spray would be effective in relieving such symptoms. METHODS: Twenty-three patients with radiation induced hyposalivation were recruited for this randomized, double-blind investigation. Subjects were randomly allocated to placebo or control medicaments used for eight weeks. All subjects were evaluated for the severity of their xerostomia associated symptoms prior to administration of the spray and again eight weeks later. RESULTS: The questionnaire and the visual analogue scale did not reveal any improvements in the dry mouth symptoms between cases and controls. Side-effects were reported among cases, mostly mild and tolerable. All patients taking pilocarpine (with base salivary flow rates > 0ml/min) demonstrated improvement in stimulated and unstimulated salivary flow rates. Candida counts decreased among the cases and controls although decrease among the cases was much greater. CONCLUSIONS: The results obtained indicate that provided residual functioning salivary tissue exists, pilocarpine used as formulated is effective and warrants further investigation.

[Value of neuroradiologic procedures in preoperative assessment of cervical myelopathy]. / Wertigkeit neuroradiologischer Verfahren bei der präoperativen Beurteilung der zervikalen Myelopathie.

The diagnostic value of computed tomography (CT), myelography, myelo-CT and magnetic resonance imaging (MRI) was retrospectively investigated in 94 patients in whom Cloward's operation had been performed due to symptoms of cervical myelopathy (CM). In 55 patients with "classical" cervical spondylotic myelopathy all investigated diagnostic procedures demonstrated a comparably high degree of sensitivity and specificity, thus proving comparable for diagnosing pathological alterations of the cervical spine. In 39 patients with CM as a consequence of an acute cervical disk prolapse, however, MRI was superior and offered the highest diagnostic accuracy. The following general diagnostic strategy in patients with CM can be suggested: Conventional plain film radiography of the cervical spine, axial CT of the involved segments and MRI of the cervical spine in sagittal and transversal orientation, using T1 and T2 weighted pulse sequences. The combined use of these techniques allows the exact evaluation of any relevant structure alterations of the cervical spine that determine differential therapeutic approaches.

Stabilizing hemostatic clamp for arterial anastomosis in microneurosurgery. Technical note.

The authors describe a "stabilizing hemostatic clamp" of their own design for use in end-to-side anastomosis. Its application facilitates simultaneous stabilization and hemostasis of the cortical artery at the site where anastomosis is to be performed. Using this instrument, the authors have performed anastomosis of the superficial temporal artery with a branch of the middle cerebral artery in 60 patients. On evaluation of the clinical effects of the treatment and results of control angiography, and taking into account the authors' relatively small experience with this type of surgical treatment, they conclude that their new clamp facilitates this form of surgery.

[Post-traumatic hematoma of the posterior cranial fossa in a 4-year-old boy with hemophilia A]. / Pourazowy krwiak tylnego dolu czaszkowego u czteroletniego chlopca z hemofilia A.

A case of a rare post-traumatic complication of haemophilia A is reported. Similarly as other authors an atypical clinical course and growing internal hydrocephalus were observed in the present case. Haemorrhagic diathesis prolonged only the period of healing of the surgical wound.
