ABSTRACT

@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

ABSTRACT

AIM: Within New Zealand (NZ) there is limited research concerning demographics and utilisation of the Emergency Department (ED) for dental-related conditions. The aim of this research was to identify the prevalence of dental presentations to Waikato Hospital ED, defining patient demographics, discharge diagnoses, management, and re-presentation rates. METHODS: Patients who presented to the Waikato Hospital ED from 2015 to 2019 with ICD-10 dental diagnoses were included in the study. Data collected included patient demographics, discharge diagnosis and management of these presentations. Statistical analysis was completed using IBM SPSS Statistical Version 26.0. RESULTS: Over the five-year study period, 4030 presentations to Waikato Hospital ED were dentally related, making up 0.98% of all ED presentations. Patients were primarily male (54%), NZ European (45%) or Maori (42%), from regions of high deprivation, presenting outside of work hours (68%). Seventy-three percent of dental presentations were non-traumatic. Ninety percent of patients were discharged with symptomatic management. Of patients admitted only 4% required management under general anaesthesia (GA). Representation occurred in 6% of patients, primarily for non-traumatic dental disease (89%). Fifty-one percent of re-attenders were male, 42% Maori and 50% of patients had a deprivation index of 9 or 10. Forty-one percent of patients re-presented within a week. CONCLUSION: At Waikato Hospital, males, NZ European, and patients of high deprivation most commonly presented to ED for dental related presentation, which were primarily non-traumatic in origin. Many patients did not require hospital care, and were managed by ED and discharged. Few patients re-presented to ED for further care. Dental presentations to ED are potentially preventable, and may be related to barriers such as cost, access or health knowledge, or an increased need. Further research is required on strategies to reduce ED presentations for dental conditions.

ABSTRACT

OBJECTIVES: To compare tooth colour change and participant's satisfaction following: home (HB), in-office (IOB) and combined (CB) bleaching treatments. METHODS: A group of 105 participants received HB, IOB and CB treatments. HB was performed using custom-made trays and 10 % carbamide peroxide for 14 days. IOB was performed using 37.5 % hydrogen peroxide applied in 3 cycles. CB bleaching treatment involved IOB followed by HB. Tooth colour change was assessed visually (VC-ΔVC) and using a digital spectrophotometry device (ES-ΔeVS). Participant's perception of oral health, smile and straightness and whiteness of teeth were evaluated using self-reported questionnaire. Parameters/responses were evaluated/collected prior bleaching and at recalls. Linear mixed models were used to estimate between- and within-group differences. RESULTS: CB resulted in significantly higher shade difference at 15 days recall (ΔVC and ΔeVS, all p ≤ 0.046). At 6 months recall, CB group demonstrated higher ΔeVS compared to IOB (p = 0.018) but the difference was not significant between the same groups when using VC (p = 0.051). Significant colour improvement was observed among all groups at 6 months recall (all within-group p < 0.001) except older participants (≥40 years) who received HB (ΔeVS: within-group p = 0.060). Overall, self-perception of oral health and satisfaction with smile and whiteness of teeth were significantly improved in all groups (all within-group p ≤ 0.001). Satisfaction levels with straightness of teeth were significantly improved for CB and IOB overall and in younger (<40 years) participants (all within-group p ≤ 0.013). CONCLUSION: CB treatment resulted in a pronounced colour improvement when compared to both techniques used individually. All bleaching protocols resulted in significant improvement of participants' perceived oral health and satisfaction with smile and whiteness of teeth. CLINICAL SIGNIFICANCE: Accelerated whitening can be achieved using a combination of in-office and home bleaching. Patients who may accept gradual whitening of teeth can be treated effectively using a cost-effective protocol and less concentrated bleaching agents.

ABSTRACT

@#Background: The long waiting time for Tetralogy of Fallot (TOF) operation may potentially increase the risk of hypoxic insult. Therefore, the objective of this study is to determine the frequency of acute neurological complications following primary TOF repair and to identify the peri-operative risk factors and predictors for the neurological sequelae. Methods: A retrospective review of the medical and surgical notes of 68 patients who underwent TOF repair in Hospital Serdang, from January 2013 to December 2017 was done. Univariate and multivariate analyses of demographics and perioperative clinical data were performed to determine the risk for the development of acute neurological complications (ANC) among these patients. Results: ANC was reported in 13 cases (19.1%) with delirium being the most common manifestation (10/68, 14.7%), followed by seizures in 4 (5.9%) and abnormal movements in two patients (2.9%). Univariate analyses showed that the presence of right ventricular (RV) dysfunction, prolonged duration of inotropic support (≥7 days), prolonged duration of mechanical ventilation (≥7 days), longer length of ICU stays (≥7 days), and longer length of hospital stay (≥14 days), were significantly associated with the presence of ANCs (p<0.05). However, multivariate analyses did not show any significant association between these variables and the development of ANC (p>0.05). The predictors for the development of postoperative delirium were pre-operative oxygen saturation less than 75% (Odds Ratio, OR=16.90, 95% Confidence Interval, 95%CI:1.36, 209.71) and duration of ventilation of more than 7 days (OR=13.20, 95%CI: 1.20, 144.98). Conclusion: ANC following TOF repair were significantly higher in patients with RV dysfunction, in those who required a longer duration of inotropic support, mechanical ventilation, ICU and hospital stay. Low pre-operative oxygen saturation and prolonged mechanical ventilation requirement were predictors for delirium which was the commonest neurological complications observed in this study. Hence, routine screening for delirium using an objective assessment tool should be performed on these high-risk patients to enable accurate diagnosis and early intervention to improve the overall outcome of TOF surgery in this country

ABSTRACT

Young people experience high rates of mental health issues. However, many do not seek professional help. In order to encourage help-seeking behavior among young people, it is important to ensure that services are youth-friendly. This study aims to evaluate the Community Health Assessment Team (CHAT)'s mental health assessment service model using the World Health Organization (WHO) youth-friendly health service framework of accessibility, acceptability, and appropriateness (AAA), and to ascertain the extent to which the CHAT service model is youth-friendly. Three hundred young people aged 16-30 years, who had gone through CHAT mental health assessments, completed a 27-item questionnaire. Majority rated the items in the questionnaire favorably. Our results suggest that majority of the young people who accessed CHAT mental health assessment service found it to be youth-friendly.

ABSTRACT

BACKGROUND: Tightrope fixation is an emerging technique for syndesmotic fixation with promising results. However, our case series highlights the slippage of Tightrope buttons as a complication of suture button syndesmotic fixation of Weber C malleolar fractures using limited contact dynamic compression (LCDCP) plates. METHODS: We report a series of cases from our database in which slippage of the Tightrope button through the LCDCP holes in Weber C malleolar fractures was noted. We measured the medial clear space (MCS), tibiofibular clear space (TFCS), and distal tibiofibular overlap (DTFO) and computed the largest change in these measurements from the first postoperative follow-up radiographs. Patient records were reviewed for persistent symptoms that could be attributed to the loss of syndesmotic fixation and stability. RESULTS: Follow-up radiographs of 3 patients showed a slippage of the Tightrope button through the LCDCP holes. Two of the patients reported persistent ankle pain and swelling with prolonged activity. The mean increases in MCS and TFCS among these patients were 0.7 (±0.081) mm and 1.5 (±0.798) mm, respectively. The mean decrease in DTFO was 2.2 (±0.864) mm. We next highlight 3 patients with Weber C malleolar fractures who underwent suture button syndesmotic fixation using double-stacked one-third tubular plates instead of the LCDCP. CONCLUSION: This case series reported Tightrope button slippage as an early complication of syndesmotic fixation of Weber C malleolar fractures. We propose the use of double-stacked one-third tubular plates instead of the LCDCP to avoid this complication. LEVEL OF EVIDENCE: Level V, expert opinion.
