Patterns of paediatric end-of-life care: a chart review across different care settings in Switzerland.

BACKGROUND: Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease-specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end-of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. METHODS: In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long-term institutions and 10 community-based healthcare service providers throughout Switzerland. RESULTS: Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. CONCLUSIONS: The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families.

Patterns and severity of vincristine-induced peripheral neuropathy in children with acute lymphoblastic leukemia.

Vincristine, a critical component of combination chemotherapy treatment for pediatric acute lymphoblastic leukemia (ALL), can lead to vincristine-induced peripheral neuropathy (VIPN). Longitudinal VIPN assessments were obtained over 12 months from newly diagnosed children with ALL (N = 128) aged 1-18 years who received vincristine at one of four academic children's hospitals. VIPN assessments were obtained using the Total Neuropathy Score-Pediatric Vincristine (TNS©-PV), National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE©), Balis© grading scale, and Pediatric Neuropathic Pain Scale©-Five (PNPS©-5). Of children who provided a full TNS©-PV score, 85/109 (78%) developed VIPN (TNS©-PV ≥4). Mean TNS©-PV, grading scale, and pain scores were low. CTCAE©-derived grades 3 and 4 sensory and motor VIPN occurred in 1.6%/0%, and 1.9%/0% of subjects, respectively. VIPN did not resolve in months 8-12 despite decreasing dose density. VIPN was worse in older children. Partition cluster analysis revealed 2-3 patient clusters; one cluster (n = 14) experienced severe VIPN. In this population, VIPN occurs more commonly than previous research suggests, persists throughout the first year of treatment, and can be severe.

Astigmatism: risk factor for postoperative corneal haze in conventional myopic photorefractive keratectomy.

PURPOSE: To retrospectively assess risk factors other than high myopia for corneal haze in patients who had conventional photorefractive keratectomy (PRK) without mitomycin-C (MMC). SETTING: Department of Ophthalmology, Naval Hospital Camp Pendleton, California, USA. METHODS: This retrospective study comprised 362 eyes of 193 military members who had conventional PRK with the Star excimer laser system from 2004 to 2006. Study inclusion criteria were myopia less than -6.0 diopters (D) spherical equivalent with or without astigmatism, no MMC applied, and at least 3 months of postoperative data available. RESULTS: Nine eyes had grade 2 corneal haze or greater. Of these eyes, 5 had greater than 2.0 D of astigmatism and 4 had no identifiable risk factors. Clinically significant postoperative corneal haze was associated with the level of preoperative astigmatism (P<.001). CONCLUSIONS: Preoperative astigmatism was significantly associated with the development of corneal haze after conventional PRK without MMC. Based on these data, surgeons should consider prophylactic MMC use during conventional PRK procedures for patients with moderate to high levels of astigmatism (approximately >or=1.25 D).

Ocular Injuries and Cultural Influences in Afghanistan During 5 Months of Operation Enduring Freedom.

In support of Operation Enduring Freedom, American, North American Treaty Organization (NATO) Coalition, and Afghan forces worked together in training exercises and counterinsurgency operations. While serving at the NATO Role 3 Multinational Medical Unit, Kandahar, Afghanistan, numerous patients with explosive blast injuries (Coalition and Afghan security forces, and insurgents) were treated. A disparity was noted between the ocular injury patterns of US and Coalition forces in comparison with their Afghan counterparts, which were overwhelmingly influenced by the use, or lack thereof, of eye protection. Computed tomography imaging coupled, with a correlative clinical examination, demonstrated the spectrum of ocular injuries that can result from an explosive blast. Patient examination was performed by Navy radiologists and an ophthalmologist. A cultural analysis by was performed to understand why eye protection was not used, even if available to Afghan forces, by the injured patients in hope of bridging the gap between Afghan cultural differences and proper operational risk management of combat forces.

Medical considerations before refractive surgery retreatment.

We report a case of a significant hyperopic shift 2 years after myopic photorefractive keratectomy with an interim of stability. The patient was an otherwise healthy man who reported a sudden change in vision when climbing to altitude. Medical considerations for refractive shifts should be looked at before retreatment is proposed. Diabetes was diagnosed in our patient; after initiation of insulin, the patient's uncorrected visual acuity returned to 20/20 in both eyes.

Intraocular lens calculation adjustment after laser refractive surgery using Scheimpflug imaging.

PURPOSE: To test a new method of intraocular lens (IOL) calculation after corneal refractive surgery using Scheimpflug imaging (Pentacam HR) and partial coherence interferometry (PCI) (IOLMaster) that does not require historical data; that is, the Schuster/Schanzlin-Thomas-Purcell (SToP) IOL calculator. SETTING: Shiley Eye Center, San Diego, California, and Walter Reed National Military Medical Center, Bethesda, Maryland, USA. DESIGN: Retrospective data analysis and validation study. METHODS: Data were retrospectively collected from patient charts including data from Scheimpflug imaging and refractive history. Target refraction was calculated using PCI and the Holladay 1 and SRK/T formulas. Regression analysis was performed to explain the deviation of the target refraction, taking into account the following influencing factors: ratio of posterior-to-anterior corneal radius, axial length (AL), and anterior corneal radius. RESULTS: The regression analysis study included 61 eyes (39 patients) that had laser in situ keratomileusis (57 eyes) or photorefractive keratectomy (4 eyes) and subsequent cataract. Two factors were found that explained the deviation of the target refraction using the Holladay 1 formula; that is, the ratio of the corneal radii and the AL and the ratio of corneal radii for the SRK/T formula. A new IOL adjustment calculator was derived and validated at a second center using 14 eyes (10 patients). CONCLUSIONS: The error in IOL calculation for normal eyes after laser refractive treatment was related to the ratio of posterior-to-anterior corneal radius. A formula requiring Scheimpflug data and suggested IOL power only yielded an improved postoperative result for patients with previous corneal laser refractive surgery having cataract surgery.

Delayed diagnosis of microsporidial stromal keratitis: unusual Wessely ring presentation and partial treatment with medications against Acanthamoeba.

The authors report a case of an immunocompetent 38-year-old male who presented with an indolent keratitis that eluded diagnosis after multiple cultures taken over 9 months. He was started initially on medications against Acanthamoeba, after presenting with a nearly complete corneal ring 2 months after trauma. These medications likely partially treated his condition, thereby making laboratory diagnosis more difficult. He was identified as having Encephalitozoon hellum by PCR. The patient subsequently underwent cornea transplant after a full course of medical treatment and recovered best-corrected visual acuity of 20/20.

Visual acuity recovery after late traumatic femtosecond laser in situ keratomileusis flap loss.

We report a case of traumatic flap loss from a fingernail 2 months after femtosecond laser-assisted laser in situ keratomileusis. On presentation, the patient's uncorrected visual acuity (UCVA) was 20/400 and complete flap avulsion was noted. Irrigation and treatment with mitomycin-C were done immediately, and a bandage contact lens was inserted. The epithelium healed completely over 1 week. One month after the injury, the UCVA was 20/15(-2). This case illustrates an excellent outcome from a potentially devastating event following refractive surgery in a military member.

Direct quantitation of omega-3 fatty acid intake of Canadian residents of a long-term care facility.

An increased dietary intake of n-3 highly unsaturated fatty acids (HUFA; >or=20 carbons, >or=3 carbon-carbon double bonds), particularly eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3), is associated with the decreased risk and incidence of several morbidities afflicting the elderly, including cognitive decline, dementia, rheumatoid arthritis, and macular degeneration. In this study, the dietary intake and blood levels of fatty acids were directly determined in residents of a retirement home or assisted living phase of a continuum of care facility for Canadian seniors. Finger-tip-prick blood samples, 3-day food duplicates, and 3-day food records were collected. The fatty acid composition of food duplicates and blood was determined by gas chromatography. Fifteen participants (7 male, 8 female; 87.1 +/- 4.8 years of age) completed the protocol. The daily intake of EPA and DHA combined, determined directly, was 70 mg (95% CI, 41-119) or 0.036% of total energy (95% CI, 0.022-0.058). In finger-tip-prick blood, the percent of n-3 HUFA in total HUFA of whole blood, a biomarker of n-3 polyunsaturated fatty acid status, was 28.8 +/- 5.2%. Correlations between daily n-3 HUFA intake and n-3 HUFA in blood were not significant (r = 0.14; n = 15), but became significant after the removal of 2 participants who appeared to consume fish irregularly (r = 0.59; n = 13). The n-3 HUFA intake and corresponding n-3 HUFA blood levels of Canadian long-term care residents are lower than levels estimated to prevent several morbidities associated with aging.
