Femoral Stem Survivorship in Dorr Type A Femurs After Total Hip Arthroplasty Using a Cementless Tapered Wedge Stem: A Matched Comparative Study With Type B Femurs

Background

There is a lack of understanding on relationship between the femoral geometry and outcomes of total hip arthroplasty (THA). We investigated clinical and radiographic outcomes of THA using a cementless tapered wedge stem in patients with Dorr type A proximal femoral morphology and compared with those of type B femurs at a minimum follow-up of 5 years.

Cribado de cáncer de cabeza y cuello en pacientes candidatos a trasplante hepático

IntroductionLiver transplantation is the only alternative treatment in patients in end-stage liver function. In many cases the need for liver transplantation is a consequence of the toxic effects of alcohol.The aim of our study was to determine if patients who are candidates for a liver transplant require a systematic exploration of the head and neck to rule out malignant lesions in this area.Patients and methodsAll the candidates for a liver transplant, between 2011 and 2017, were included in our study. All of them underwent a systematic exploration of the head and neck by an otolaryngologist to rule out malignancy of the head and neck.ResultsA total of 141 patients were included in our study. In 2 of them (1.3%) a carcinoma of the head and neck was detected (one of the oropharynx and the other of the larynx). Both patients were asymptomatic from an ENT point of view. They were treated with chemoradiotherapy. One of them died during follow-up due to the appearance of a metachronous lung tumour. The other is free of disease 2 years after diagnosis but without having been transplanted. Both patients had a history of smoking and high alcohol intake.ConclusionsIn patients who are candidates for a liver transplant who have a history of smoking and / or high alcohol intake, a pretransplant head and neck study including pharyngo-laryngeal fibroscopy is indicated.     

An unusual case of a brain abscess arising from an odontogenic infection

A brain abscess that originates from an odontogenic infection, although rare, can at times be difficult to diagnose, especially in the context of pain and trismus. We report a rare case of odontogenic infection as a result of an infected maxillary third molar, causing an infratemporal and temporalis collection, resulting in a brain abscess with concurrent cerebritis. This is a clinical case review documenting an uncommon but potentially fatal complication.     

头颈部嗜酸性淋巴肉芽肿14例临床分析

目的 探讨头颈部嗜酸性淋巴肉芽肿（ELG）的临床特点,以提高临床诊治水平。方法 回顾性分析中山大学孙逸仙纪念医院口腔颌面外科2003 - 2012年14例头颈部ELG的临床资料,分别从研究对象的发病年龄、性别、发病部位、实验室检查、病理、临床表现、治疗及预后等方面进行总结。结果 所有病例均经病理检查确诊。治疗后随访时间为1 ~ 13个月,其中1例经肿块切除术,术后5个月复发;1例经药物治疗,治疗后4个月复发。其余12例患者预后良好,随访期间未出现病情进展或复发。结论 ELG常表现为一种无痛的软组织病变,好发于男性,多见于中青年人,好发部位为腮腺区、颈部等。主要依靠病理确诊,最佳治疗方案是手术切除结合适当剂量的放疗。     

The best practice tariff and hip fractures: How can Northern Ireland keep up?

IntroductionCurrent hip fractures guidelines recommend surgery within 36 h of admission. The 2011 National Hip Fracture Database (NHFD) report shows our institute has the fewest patients meeting this target (9%). Northern Irelands' exclusion from the “Best Practice Tariff” means no incentive-led treatment or prioritisation of hip fracture patients.MethodWe performed a systematic review of post-operative results to highlight deficiencies in delivery of patient care. We reviewed 702 patients admitted between September 2009 and April 2012. Patients were prospectively identified and added to our Fracture Outcome and Research Database (FORD). Results were compared to national average values from the NHFD.Results16.7% of patients met the 36-h target to theatre compared to the UK average of 66%. 81.7% underwent a pre-operative orthogeriatric review. The main reasons for surgical delay were inadequate theatre space (58%) and medically unfit patients (29%). After exclusion of medically unfit patients, medically fit patients were divided into delayed surgery and not delayed categories. Medically fit patients who had delayed surgery had inferior outcomes- longer hospital stay and higher mortality as an inpatient and at 30 days.ConclusionWithout a change in funding, Northern Ireland will struggle to compete with the UK mainland and decrease mortality in this patient group.
