Abstract
Dental surgeons may encounter in their clinical practice patients who present with aggressive pathologies that require early diagnosis and prompt treatment. This action may limit the extent of tissue damage and, where relevant, improve survival outcome. Clinicians should therefore be aware of the range of resective, reconstructive and rehabilitative options that are available in the management of these patients. We present our experience with the free fibula flap used for oromandibular reconstruction; this was undertaken in 21 patients following resective surgery for malignant pathology, cytologically benign but biologically aggressive odontogenic pathology and radiation induced osteonecrosis. We also review the history, surgical anatomy, surgical assessment and potential complications that are relevant to the free fibula flap.

Abstract
BACKGROUND Egg allergy is common and although resolution to uncooked egg has been demonstrated, there is lack of evidence to guide reintroduction of well-cooked egg. OBJECTIVES To examine the rate of resolution to well-cooked, compared with uncooked egg in children, and safety of egg challenges. METHOD A longitudinal study of egg-allergic children from 2004 to 2010, who underwent challenge with well-cooked and if negative, uncooked egg. Participants underwent repeat annual challenges and egg-specific IgE measurement. RESULTS One hundred and eighty-one open egg challenges were performed in 95 children whose median age of allergy onset was 12 months. Fifty-three of 95 (56%) had at least one annual repeat challenge. Pre-study historical reactions occurred to baked egg in five (5%), lightly cooked in 58 (61%) and uncooked in nine (9%); respiratory reactions occurred in 11 (12%) and seven (7%) had anaphylaxis; adrenaline was used during five reactions. There were 77 well-cooked and 104 uncooked egg challenges. Tolerance was gained twice as rapidly to well-cooked than uncooked egg (median 5.6 vs. 10.3 years; P<0.0001) and continued to 13 years; hazard ratio 2.23 (95% confidence interval 1.6-3.9). Nearly 1/3 had resolved allergy to well-cooked egg at 3 years and 2/3 at 6 years. Of 28/77 (37%) positive well-cooked egg challenges, 65% had cutaneous symptoms, 68% gastrointestinal and 39% rhinitis, with no other respiratory reactions. Adrenaline was not required. CONCLUSIONS AND CLINICAL RELEVANCE RESOLUTION: of egg allergy takes place over many years, with children outgrowing allergy to well-cooked egg approximately twice as quickly as they outgrow allergy to uncooked egg. There were no severe reactions to well-cooked egg challenge, and adrenaline was not required. Our data support initiation of home reintroduction of well-cooked egg from 2 to 3 years of age in children with previous mild reactions and no asthma. Resolution continues to occur in older children, so that despite an earlier positive challenge, attempts at reintroduction should be continued.

Abstract
BRCA1 overexpression and phosphoinositide 3-kinase (PIK3CA) pathway activation are involved in the resistance to DNA damaging agents. Thus, we hypothesized that BRCA1 protein expression and activating PIK3CA mutations are potential tumor biomarkers for the chemotherapeutic response to doxorubicin/cyclophosphamide plus docetaxel in locally advanced breast cancer. Informed consent was obtained and clinical, pathological and response data were collected. BRCA1 protein expression levels were assessed by immunohistochemistry of the archived tissue by two independent pathologists. The PIK3CA mutation status was assessed by nested PCR amplification and DNA sequencing. BRCA1 protein levels and the PIK3CA mutation status were correlated with pathological complete response and a partial response or better using the Chi-square test, Fisher's exact test and logistic regression. Of the 136 eligible participants, 59 samples could be analyzed. There was a trend of relatively low levels of BRCA1 protein achieving a pathological complete response (pCR), although this was not statistically significant [odds ratio (OR)=1.74; p=0.437]. Twenty-eight percent of patients had PIK3CA mutations, but no statistically significant association with pCR (OR=0.977; p=0.971) was noted. Neither BRCA1 protein levels (OR=1.18; p=0.818) nor PIK3CA mutations (OR=1.03; p=0.971) appeared to be associated with the likelihood of achieving a partial response or better from neoadjuvant chemotherapy. PIK3CA wild-type mutation status showed a trend towards an increased likelihood of not presenting with inflammatory disease (OR=5.34; p=0.101). In this exploratory study, neither BRCA1 protein expression levels nor the presence of PIK3CA mutations were significantly associated with chemotherapy response in locally advanced breast cancer. However, the relatively small sample size limits the overall interpretation.

Abstract
BACKGROUND Double-blinded challenges are widely used for diagnosing food allergy but are time-consuming and cause severe reactions. Outcome relies on subjective interpretation of symptoms, which leads to variations in outcome between observers. Facial thermography combined with nasal peanut challenge was evaluated as a novel objective indicator of clinical allergy. METHODS Sixteen children with positive blinded peanut challenge underwent nasal challenge with 10 μg peanut protein or placebo. Mean skin temperatures were recorded from the mouth and nose using infrared thermography over 18 min. RESULTS The area under curve of nasal skin temperature was significantly elevated after peanut vs placebo (18.2 vs 4.8°Cmin). The maximum increase in temperature was also significantly greater after peanut: mean difference +0.9°C. CONCLUSION This feasibility study shows thermography can detect inflammation caused by nasal challenges whilst employing one thousand-fold less peanut than an oral challenge. This novel technique could be developed to provide a rapid, safe and objective clinical allergy test.

Abstract
Dental curricula in UK dental schools are seemingly excising ever more skills as each generation of students is trained. This has implications for the quality of education held by the latest dental graduates, and furthermore potentially for the standard of care that their patients may receive. This leaves us today somewhat nostalgic for a bygone era when dental undergraduate education was replete with a fuller repertoire.

Abstract
In order to find out the fluctuation of pain by weather change, a descriptive cross-sectional study was conducted among 138 individuals having musculoskeletal disorders (MSDs) attending the out patient department (OPD) of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, during March 2004 to June 2004. Data were collected by face to face interview employing a pre-tested interview schedule containing structured questions. Among 138 respondents, male were predominant (52.2%). Mean age of the respondents was 39.42±10.79 years, while the most common age group was found as '31 to 40 years'. By occupation, majority were housewives (40.58%), followed by businessmen (29.71%), service holder (15.22%), laborer (7.97%), and students (6.52%). The primary sites of pain were back and low back (38.4%), knee (24.6%), leg (8.7%), ankle and heel (8.0%), hand and wrist (6.5%), neck (5.8%), shoulder (5.8%), and elbow (2.2%). Highest number (47.8%) patients reported aching pain, while one fifth (20.3%) of them experienced burning pain. About 36.2 percent respondents mentioned 'prolonged standing' as the main cause of pain aggravation, while almost half (48.6%) of the patients perceived that 'application of heat' was the key relieving factor of their pain. About two third (63%) of the respondents were sensitive to weather change; among them 56.3 percent reported that their pain increased during cold weather. Moreover, more than two third (67.4%) study-patients experienced deterioration of pain due to seasonal variation; of them 59.1 percent reported that their pain was exacerbated in winter season. Of all respondents, less than one third (30.4%) experienced aggravation of pain due to lunar change; of them majority (85.7%) experienced increased pain during dark fortnights. Our study concluded that weather change might have an important role in fluctuation of pain among individuals having musculoskeletal disorders.

Abstract
BACKGROUND Breast cancer 1 (BRCA1) protein inactivation in sporadic ovarian carcinoma (OC) is common and low BRCA1 expression is linked with platinum sensitivity. The clinical validation of BRCA1 as a prognostic marker in OC remains unresolved. PATIENTS AND METHODS In 251 patient samples from the NCIC CTG clinical trial, OV.16, BRCA1 protein expression was determined by immunohistochemistry. RESULTS For all patients, when BRCA1 score was analyzed as a continuous variable, there was no significant correlation between BRCA1 protein expression and progression-free survival (PFS) [adjusted hazard ratio (HR) = 1.15 (0.96-1.37), P = 0.12] or response rate [HR = 0.89 (0.70-1.12), P = 0.32]. In the 116 patients with minimal residual disease (RD), higher BRCA1 expression correlated significantly with worse PFS [HR = 1.40 (1.04-1.89), P = 0.03]. Subgroup analysis divided patients with minimal RD into low (BRCA1 ≤2.5) and high (BRCA1 >2.5) expression groups. Patients with low BRCA1 expression had a more favorable outcome [median PFS was 24.7 and 16.6 months in patients with low and high BRCA1, respectively; HR = 0.56 (0.35-0.89), P = 0.01]. CONCLUSIONS This study suggests that BRCA1 protein is a prognostic marker in sporadic OC patients with minimal RD. Further research is needed to evaluate BRCA1 as a predictive biomarker and to target BRCA1 expression to enhance chemotherapeutic sensitivity.

Abstract
AIMS/HYPOTHESIS Although diabetes is an established risk factor for myocardial infarction (MI), disease control may vary. HbA(1c) is a reliable index of ambient glucose levels and may provide more information on MI risk than diabetes status. METHODS The relationship between HbA(1c) levels in MI patients and controls who participated in the 52 country INTERHEART study was analysed. RESULTS In 15,780 participants with a HbA(1c) value (1,993 of whom had diabetes), the mean (SD) levels for HbA(1c) were 6.15% (1.10) in the 6,761 MI patients and 5.85% (0.80) in the control participants. After adjustment for age, sex and nine major MI risk factors (including diabetes), higher HbA(1c) fifths above the lowest fifth (HbA(1c) <5.4%) were associated with progressively higher OR of MI, with OR for the highest HbA(1c) fifth (≥ 6.12%) being 1.55 (95% CI 1.37-1.75). When analysed as a continuous variable after adjustment for the same factors, every 1% higher HbA(1c) value was associated with 19% (95% CI 14-23) higher odds of MI, while every 0.5% higher HbA(1c) was associated with 9% higher odds of MI (95% CI 7-11). Concordant relationships were noted across subgroups, with a higher OR noted in younger people, patients without diabetes or hypertension, and those from some regions and ethnicities. CONCLUSIONS/INTERPRETATION The HbA(1c) value provides more information on MI odds than self-reported diabetes status or many other established risk factors. Every 1% increment independently predicts a 19% higher odds of MI after accounting for other MI risk factors including diabetes.
