Improving outcomes in acute and chronic periprosthetic hip and knee joint infection with a multidisciplinary approach.

AIMS: Periprosthetic hip and knee infection remains one of the most severe complications following arthroplasty, with an incidence between 0.5% to 1%. This study compares the outcomes of revision surgery for periprosthetic joint infection (PJI) following hip and knee arthroplasty prior to and after implementation of a specialist PJI multidisciplinary team (MDT). METHODS: Data was retrospectively analyzed from a single centre. In all, 29 consecutive joints prior to the implementation of an infection MDT in November 2016 were compared with 29 consecutive joints subsequent to the MDT conception. All individuals who underwent a debridement antibiotics and implant retention (DAIR) procedure, a one-stage revision, or a two-stage revision for an acute or chronic PJI in this time period were included. The definition of successfully treated PJI was based on the Delphi international multidisciplinary consensus. RESULTS: There were no statistically significant differences in patient demographics or comorbidities between the groups. There was also no significant difference in length of overall hospital stay (p = 0.530). The time taken for formal microbiology advice was significantly shorter in the post MDT group (p = 0.0001). There was a significant difference in failure rates between the two groups (p = 0.001), with 12 individuals (41.38%) pre-MDT requiring further revision surgery compared with one individual (6.67%) post-MDT inception. CONCLUSION: Our standardized multidisciplinary approach for periprosthetic knee and hip joint infection shows a significant reduction in failure rates following revision surgery. Following implementation of our MDT, our success rate in treating PJI is 96.55%, higher than what current literature suggests. We advocate the role of a specialist infection MDT in the management of patients with a PJI to allow an individualized patient-centred approach and care plan, thereby reducing postoperative complications and failure rates.

Care of culturally diverse patients undergoing ophthalmic surgery.

We live and work in a multicultural world and need to be knowledgeable about culture and how it affects the quality of care given to patients. Although people of the non-dominant culture may have knowledge of the English language, many have limited English proficiency (LEP), a topic of great importance for the ophthalmic patient in the healthcare setting where populations grow increasingly diverse. Knowing how to communicate effectively with patients includes an understanding oflanguage. Because of the need for accuracy in ophthalmic surgical treatment, it is critical for ophthalmic caregivers to learn the skills necessary to communicate proficiently with their patients in order to assure a positive outcome in patient care. To achieve this goal, ophthalmic healthcare providers need to realize that accessing medical interpreter services is a necessary component of providing culturally sensitive patient care.

Care of the child undergoing an examination under anesthesia for retinoblastoma.

In conclusion, the welfare of the child is of paramount importance in the detection and treatment ofretinoblastoma. It is important for the parents to feel comfortable with the care their child is receiving since they are facing a lengthy course of therapy. Consequently, the family will require the support of the entire ambulatory surgical daycare team for years to come.

One year prospective survey of Candida bloodstream infections in Scotland.

A 12 month survey of candidaemia in Scotland, UK, in which every Scottish hospital laboratory submitted all blood isolates of yeasts for identification, strain typing and susceptibility testing, provided 300 isolates from 242 patients, generating incidence data of 4.8 cases per 100,000 population per year and 5.9 cases per 100,000 acute occupied bed days; 27.9 % of cases occurred in intensive care units. More than half the patients with candidaemia had an underlying disease involving the abdomen, 78 % had an indwelling intravenous catheter, 62 % had suffered a bacterial infection within the 2 weeks prior to candidaemia and 37 % had undergone a laparotomy. Candida albicans was the infecting species in 50 % of cases, followed by Candida glabrata (21 %) and Candida parapsilosis (12 %). Seven cases of candidaemia were caused by Candida dubliniensis, which was more prevalent even than Candida lusitaniae and Candida tropicalis (six cases each). Among C. glabrata isolates, 55 % showed reduced susceptibility to fluconazole, but azole resistance among other species was extremely low. Multilocus sequence typing showed isolates with high similarity came from different hospitals across the country, and many different types came from the hospitals that submitted the most isolates, indicating no tendency towards hospital-specific endemic strains. Multiple isolates of C. albicans and C. glabrata from individual patients were of the same strain type with single exceptions for each species. The high prevalence of candidaemia in Scotland, relative to other population-based European studies, and the high level of reduced fluconazole susceptibility of Scottish C. glabrata isolates warrant continued future surveillance of invasive Candida infections.

The spectrum of HIV-related disease in rural Central Thailand.

To determine the spectrum of HIV-related illnesses presenting to a rural primary and secondary healthcare facility in Central Thailand, a cross-sectional study was conducted. Routinely collected data were extracted from outpatient medical notes for all adult HIV-infected new attenders of the Manorom Christian Hospital Infectious Disease Clinic. Data concerning inpatient admissions of HIV-infected individuals were collected from ward admission books and discharge summaries. Complete data were available for 229 outpatients, 70% of whom were men. The median age at presentation was 31 years for men and 30 years for women. The majority of the outpatients were married (69%) and infected heterosexually (91%). The commonest conditions requiring admission were cryptococcal meningitis (15%), bacterial pneumonia (12%), extrapulmonary tuberculosis (12%), Pneumocystis carinii pneumonia (7%), cerebral toxoplasmosis (4%) and pulmonary tuberculosis (3%). Of the patients presenting for the first time, 32% had AIDS-defining illnesses. Presentations with some conditions, such as tuberculosis and septicemia, were fewer than expected. The common opportunistic infections among HIV-infected adults in this rural region are treatable and preventable. Most patients present with advanced disease and earlier diagnosis, through improved access to voluntary counseling and testing, would enable them to receive appropriate preventive therapies and antiretrovirals as they becomes available. The high prevalence of cryptococcal disease suggests that prophylactic anti-fungal therapy may be of value in this area. Septicemia and tuberculosis may be under-diagnosed, highlighting the need for improved diagnostic laboratory facilities or treatment based upon validated clinical algorithms. Community care and palliative care services for HIV-infected individuals will increasingly be required in this region.
