RESUMO
Objective: This article describes a case of polymicrobial Arcanobacterium haemolyticum pharyngitis and sinusitis complicated by intracranial complications and reviews similar cases in the literature. Case summary: A 21-year-old immunocompetent male presented with symptoms of sore throat, rhinorrhoea, lethargy, headache, and rash. Imaging demonstrated sinusitis, pre-septal sinusitis, peritonsillar abscess formation, subdural empyema and cerebritis. He was managed with endoscopic sinus surgery, craniotomy for evacuation of subdural empyema and antibiotics. Microbiological samples demonstrated growth of A. haemolyticum, strep. anginosus, and fusobacterium necrophorum. He subsequently developed a cerebral abscess requiring stereotactic needle drainage. After a prolonged course of antibiotics, the patient was discharge and made a good recovery. Discussion: A. haemolyticum is an uncommon cause of non-streptococcal pharyngitis that may occur alongside other microorganisms and is rarely associated with severe intracranial complications. This organism and its antibiotic susceptibility patterns should be considered in complicated upper respiratory tract infections in immunocompetent hosts. Penicillins and macrolide antibiotics form the mainstay of therapy for A. haemolyticum.
RESUMO
OBJECTIVE: Juvenile Otosclerosis (JO) and Congenital Stapes Footplate Fixation (CSFF) are rare ossicular chain disorders seen in the paediatric population and present with conductive hearing loss. Ongoing controversy exists regarding the role of surgical intervention in JO and CSFF given the poorer hearing outcomes and complications when compared with surgical intervention for adult otosclerosis. The objective of this study is to assess the published data on the surgical outcomes of JO and CSFF in order to guide clinicians and counsel patients on the various medical options for these disease entities. METHODS: A systematic review of MEDLINE, EMBASE and Cochrane was performed with inclusion criteria of children with JO or CSFF and hearing outcomes following stapes surgery. Studies identified by the search were reviewed and assessed by two independent reviewers in line with the PRISMA guidelines. RESULTS: 464 articles were initially reviewed and 28 articles met inclusion in the systematic review and meta-analysis. A total of 810 ears (473 and 337 cases of JO and CSFF respectively) underwent stapes surgery. Average age at time of surgery for JO and CSFF was 14.3 and 10.2 years old respectively. The mean pre-operative Air-Bone-Gap (ABG) for JO and CSFF was 31.8 ± 5.2 dB and 39.4 ± 10 dB respectively. Following stapes surgery, the mean post-operative ABG for JO and CSFF was 9.6 ± 6 dB and 19.2 ± 12.5 dB respectively. Surgical success rate (defined as ABG <10 dB) was 81% for JO and 41% for CSFF. Mean ABG gain for JO and CSFF was 24.8 dB (95% CI: 18.6-33.1) and 22.6 dB (95% CI: 18.4-27.8) respectively. The reported number of dead ears was 4/473 (0.8%) for JO and 2/337 (0.6%) for CSFF. 23 cases (2.8%) reported sensorineural hearing loss (SNHL) >10 dB. CONCLUSION: CSFF was associated with poorer hearing outcomes compared to JO, however both entities showed similar improvement in ABG post operatively. Counselling patients and their families on the surgical success rates and complications of JO or CSFF is an important part of the decision making process when deciding between a surgical option or conservative measures such as hearing aids.

PURPOSE OF REVIEW: Necrotizing fasciitis of the face is uncommon but potentially life threatening. With adequate multidisciplinary treatment, mortality and has significantly improved. This article highlights current concepts and supporting literature in the management of facial necrotizing fasciitis. RECENT FINDINGS: Management of necrotizing fasciitis involving the face requires a multisciplinary team approach, including early medical and surgical intervention. With early haemodynamic support, broad spectrum antibiotics and aggressive surgical debridement, mortality has reduced significantly. Soft-tissue reconstruction can be effectively utilized once the infection has been adequately treated. Although some adjunctive treatment such as vacuum assisted closure dressing has shown to be of benefit, other treatments such as hyperbaric oxygen remains controversial. SUMMARY: Necrotizing fasciitis is an aggressive soft tissue involving that rapidly spreads along fascial planes. Necrotizing fasciitis involving the face is rare owing to its rich blood supply but is also difficult to manage due to the complex regional anatomy. Common sources are odontogenic, sinugenic, peritonsillar or salivary gland infections and often polymicrobial. The principles of treatment include early and aggressive haemodynamic support, broad spectrum antibiotics and aggressive surgical debridement. Often times repeat debridements following close monitoring is required. Reconstructive options are viable only after the infection has been adequately treated. Although mortality has significantly improved, mediastinal involvement, multiple comorbidities and delayed treatment confers a worse prognosis.

INTRODUCTION: Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are blistering cutaneous disorders that often manifest with epidermal and mucosal necrosis. In extreme cases, the upper or bronchial airways are threatened, necessitating intubation and mechanical ventilation. This systematic review and meta-analysis examines the prevalence of mechanical ventilation (MV) in patients with SJS or TENS, despite maximal medical therapy, and additionally aims to identify the risk factors associated with this requirement. MATERIALS AND METHODS: A systematic review of the literature was performed using the PRISMA guidelines and meta-analysis of proportions. RESULTS: Six articles were included, with pooled total of 18648 cases. The weighted prevalence of MV was 27.5% (95%CI 17.8-39.9%). The need for MV was more closely associated with TEN, compared to SJS (OR 4.40, 95%CI 2.73-7.10, I2=48%, p<.00001.) Risk factors associated with the need for MV included bacteremia (OR 5.02, 95%CI 2.87-8.79, I2=0%, p<.00001), shock/organ failure on admission (OR 261.99, 95%CI 21.88-3137, I2=71, p<.0001), total body surface area (TBSA) >30% (OR 4.47, 95%CI 1.41-14.20, I2=71, p=.01.). CONCLUSION: Limited published evidence with significant heterogeneity exists within the literature regarding the need for MV in SJS and TEN. Greater cutaneous involvement, and more critically unwell patients appear more likely to require MV.

Fracture risk evaluation of postmenopausal women is suboptimal, but most women undergo screening mammography. Digital X-radiogrammetry (DXR) determines bone mineral density (BMD) at the metacarpal shaft and can be performed on mammography equipment. This study examined correlations between DXR and dual-energy X-ray absorptiometry (DXA) in women undergoing mammography, to identify optimal DXR thresholds for triage to osteoporosis screening by central DXA. Postmenopausal women over age 50 years, recruited from Westmead Hospital's Breast Cancer Institute, underwent mammography, DXR and DXA. Agreements were determined using the area under the receiver operator characteristic (AUC ROC) curve and Lin's concordance correlation coefficient. Optimal DXR T-scores to exclude osteoporosis by DXA were determined using the Youden's method. Of 200 women aged 64 ± 7 years (mean ± standard deviation [SD]), 82% had been diagnosed with breast cancer and 37% reported prior fracture. DXA T-scores were ≤ -1 at the spine, hip or forearm in 77.5% and accorded with DXR T-scores in 77%. For DXR and DXA T-scores ≤ -2.5, the AUC ROC was 0.87 (95% confidence interval [CI], 0.81-0.94) at the 1/3 radius, and 0.74 (95% CI, 0.64-0.84) for hip or spine. DXR T-scores > -1.98 provided a negative predictive value of 94% (range, 88%, 98%) for osteoporosis by central DXA. In response to a questionnaire, radiography staff responded that DXR added 5 minutes to patient throughput with minimal workflow impact. In the mammography setting, triaging women with a screening DXR T-score < -1.98 for DXA evaluation would capture a significant proportion of at-risk women who may not otherwise be identified and improve current low rates of osteoporosis screening. © 2022 The Authors.

RESUMO
BACKGROUND: Human papilloma virus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) continues to increase in incidence. Patients are younger, non-smokers and most commonly present with a neck mass often with no other symptoms. This altered presentation compared with non-HPV OPSCC may not be recognized by medical practitioners, leading to delayed diagnosis. METHODS: Patients with histopathological confirmation of OPSCC and known HPV and/or P16 status who presented to our institution between 2012-2017 inclusive were included in the study. Demographic data, tumour characteristics and presenting symptoms were retrospectivxely obtained from both electronic- and paper-based records. Descriptive statistics were used to report demographic data and the two sample t-test and Fisher's exact test were used to compare groups based on HPV status. Time to diagnosis was also reported. RESULTS: A total of 184 patients were included in the study. The majority of patients were male (85.4%) and HPV + (85.3%). The tonsillar complex (53.8%) and tongue base (42.4%) were the most common primary sites. HPV+ patients were less likely to smoke (17.8%) and they commonly presented with a neck mass (39.5% alone or with other symptoms 61.2%). Time to diagnosis in the HPV+ group was longer (15 weeks). CONCLUSION: Our review has highlighted the altered presentation of OPSCC due to the increased incidence of HPV infection. We showed a delayed time to diagnosis in HPV+ OPSCC compared with non-HPV disease. This confirms the importance of focusing our efforts on educating medical practitioners and creating further awareness to facilitate early detection and treatment.

BACKGROUND: Acinic cell carcinoma (AcCC) is a rare malignant neoplasm of the salivary glands and generally considered to be a low-grade tumour. Surgical treatment is often curative, but a more aggressive high-grade variant has been associated with poorer survival and propensity for distant metastasis. No standard treatment guidelines exist and the approach to treatment is varied in the published series. The aim of this study is to present the experience of three major hospitals in Sydney, Australia, in treating AcCC of the salivary gland, with a focus on clinico-pathological features of disease and their associations with survival outcomes. METHODS: Adult and paediatric cases of AcCC of the salivary gland during the time period 1979-2018 were retrospectively included. Demographic, clinico-pathological, treatment and survival outcome data were extracted. Survival analysis was undertaken to assess the effect of clinical and pathological variables on overall and disease-free survival. RESULTS: Thirty-two cases were reviewed (29 adult and three paediatric). Thirty tumours (93.8%) were parotid gland primary tumours. Mean overall and disease-free survival was 17.0 ± 0.7 and 16.0 ± 0.9 years, respectively. Features associated with poorer survival were cT staging >1, presence of preoperative clinical facial nerve deficit and local recurrence. Positive margins were associated with recurrence. CONCLUSION: These data suggest that disease-free and overall survival in AcCC of the salivary gland is excellent with surgery as the first-line treatment. Poor survival outcomes are uncommon and may be associated with locally advanced disease in the presence of other well-established high-risk features.
