EGFR inhibitor-induced folliculitis decalvans: a case series and management guidelines

Epidermal growth factor receptor (EGFR) is one of therapeutic targets in oncology for solid tumors originating from epithelial tissue, such as non-small-cell lung carcinoma (NSCLC) and breast cancer. EGFR inhibitors used in cancer treatment may cause a broad spectrum of dose-dependent cutaneous adverse events, including acneiform papulopustular rash, nail and hair disturbances, xerosis, and mucositis. The pathogenesis of the EGFR inhibitor-induced adverse reactions originates from disturbances in keratinocyte differentiation, cytokine secretion, and neutrophil chemotaxis. One of the rare, yet distressing adverse events may be folliculitis decalvans, a progressive neutrophil-driven scarring alopecia with hair tufts formation resembling doll's hair. Early diagnosis and introduction of treatment are crucial for disease prognosis since a long course of the disease leads to decreased quality of life. Here, we review the literature cases of EGFR inhibitor-induced folliculitis decalvans and provide guidance on management and prevention of this condition in oncologic patients. Furthermore, we report the first afatinib-associated folliculitis decalvans in three female patients with NSCLC.

Standardized care pathways for patients with suspected urinary bladder cancer: the Swedish experience

OBJECTIVES

To compare time intervals to diagnosis and treatment, tumor characteristics, and management in patients with primary urinary bladder cancer, diagnosed before and after the implementation of a standardized care pathway (SCP) in Sweden.

MATERIALS AND METHODS

Data from the Swedish National Register of Urinary Bladder Cancer was studied before (2011-2015) and after (2016-2019) SCP. Data about time from referral to transurethral resection of bladder tumor (TURBT), patients and tumor characteristics, and management were analyzed. Subgroup analyses were performed for cT1 and cT2-4 tumors.

RESULTS

Out of 26,795 patients, median time to TURBT decreased from 37 to 27 days after the implementation of SCP. While the proportion of cT2-T4 tumors decreased slightly (22-21%, p < 0.001), this change was not stable over time and the proportions cN + and cM1 remained unchanged. In the subgroups with cT1 and cT2-4 tumors, the median time to TURBT decreased and the proportions of patients discussed at a multidisciplinary team conference (MDTC) increased after SCP. In neither of these subgroups was a change in the proportions of cN + and cM1 observed, while treatment according to guidelines increased after SCP in the cT1 group.

CONCLUSION

After the implementation of SCP, time from referral to TURBT decreased and the proportion of patients discussed at MDTC increased, although not at the levels recommended by guidelines. Thus, our findings point to the need for measures to increase adherence to SCP recommendations and to guidelines.

Improving outcomes and quality of life for patients with transfusion-dependent β-thalassemia: recommendations for best clinical practice and the use of novel treatment strategies

INTRODUCTION

β-thalassemia is one of the most common inherited monogenic diseases. Many patients are dependent on a lifetime of red blood cell (RBC) transfusions and iron chelation therapy. Although treatments have a significant impact on quality of life (QoL), life expectancy, and long-term health outcomes have improved in recent decades through safer RBC transfusion practices and better iron chelation strategies. Advances in the understanding of the pathology of β-thalassemia have led to the development of new treatment options that have the potential to reduce the RBC transfusion burden in patients with transfusion-dependent (TD) β-thalassemia and improve QoL.

AREAS COVERED

This review provides an overview of currently available treatments for patients with TD β-thalassemia, highlighting QoL issues, and providing an update on current clinical experience plus important practical points for two new treatments available for TD β-thalassemia: betibeglogene autotemcel (beti-cel) gene therapy and the erythroid maturation agent luspatercept, an activin ligand trap.

EXPERT OPINION

Approved therapies, including curative gene therapies and supportive treatments such as luspatercept, have the potential to reduce RBC transfusion burden, and improve clinical outcomes and QoL in patients with TD β-thalassemia. Cost of treatment is, however, likely to be a significant barrier for payors and patients.

IMI 2021 Yearly Digest

Purpose

The International Myopia Institute (IMI) Yearly Digest highlights new research considered to be of importance since the publication of the first series of IMI white papers.

Methods

A literature search was conducted for articles on myopia between 2019 and mid-2020 to inform definitions and classifications, experimental models, genetics, interventions, clinical trials, and clinical management. Conference abstracts from key meetings in the same period were also considered.

Results

One thousand articles on myopia have been published between 2019 and mid-2020. Key advances include the use of the definition of premyopia in studies currently under way to test interventions in myopia, new definitions in the field of pathologic myopia, the role of new pharmacologic treatments in experimental models such as intraocular pressure-lowering latanoprost, a large meta-analysis of refractive error identifying 336 new genetic loci, new clinical interventions such as the defocus incorporated multisegment spectacles and combination therapy with low-dose atropine and orthokeratology (OK), normative standards in refractive error, the ethical dilemma of a placebo control group when myopia control treatments are established, reporting the physical metric of myopia reduction versus a percentage reduction, comparison of the risk of pediatric OK wear with risk of vision impairment in myopia, the justification of preventing myopic and axial length increase versus quality of life, and future vision loss.

Conclusions

Large amounts of research in myopia have been published since the IMI 2019 white papers were released. The yearly digest serves to highlight the latest research and advances in myopia.

International consensus guidelines for phosphoglucomutase 1 deficiency (PGM1-CDG): Diagnosis, follow-up, and management

Phosphoglucomutase 1 (PGM1) deficiency is a rare genetic disorder that affects glycogen metabolism, glycolysis, and protein glycosylation. Previously known as GSD XIV, it was recently reclassified as a congenital disorder of glycosylation, PGM1-CDG. PGM1-CDG usually manifests as a multisystem disease. Most patients present as infants with cleft palate, liver function abnormalities and hypoglycemia, but some patients present in adulthood with isolated muscle involvement. Some patients develop life-threatening cardiomyopathy. Unlike most other CDG, PGM1-CDG has an effective treatment option, d-galactose, which has been shown to improve many of the patients' symptoms. Therefore, early diagnosis and initiation of treatment for PGM1-CDG patients are crucial decisions. In this article, our group of international experts suggests diagnostic, follow-up, and management guidelines for PGM1-CDG. These guidelines are based on the best available evidence-based data and experts' opinions aiming to provide a practical resource for health care providers to facilitate successful diagnosis and optimal management of PGM1-CDG patients.

Case Series and Review on Managing Abscesses Secondary to Hyaluronic Acid Soft Tissue Fillers with Recommended Management Guidelines

With the number of aesthetic soft tissue filler treatments rapidly increasing, we have witnessed an increase in complications associated with such treatments. While rare, abscesses can arise as a result of these treatments, and current detailed guidelines do not exist detailing exactly how to manage them. OBJECTIVE: Our aim was to develop evidence-based and experience-based guidelines on how to, specifically, manage abscesses secondary to hyaluronic acid dermal fillers. METHODS: A thorough MEDLINE literature search of keywords, including abscess, abscess management/treatment, hyaluronic acid, dermal fillers, and soft tissue fillers, was completed to collect specific cases of abscesses secondary to soft tissue filler. Inclusion criteria involved papers published from 2010 to 2020 that focused specifically on soft tissue fillers in the face. In addition, we looked at papers that discussed abscesses secondary to soft tissue fillers in general and their management. We also reported three cases of abscesses secondary to hyaluronic acid dermal fillers that have been described by three different practitioners, detailing their history, examination, management, and outcomes. Experience and evidence have been collated to produce management guidelines. RESULTS and CONCLUSION: It is clear that each case is unique, but there is no current universal consensus on the risk assessment before treatment nor general management of abscesses secondary to soft tissue filler. The majority of the reports and cases discussed in the paper suggested the use of co-amoxiclav along with a macrolide or quinolone for at least two weeks. Incision and drainage are universally accepted as gold standard management. Microbiology, sensitivities, and cultures are also recommended. Hyaluronidase use, while controversial, is encouraged in effectively managing abscesses secondary to hyaluronic acid dermal filler.

Non-consensual recommendations for managing bipolar II disorder

OBJECTIVE

The objective of this study is to report on the degree of consensus in experts' recommendations for managing bipolar II disorder.

METHODS

Eighteen international clinician researchers with expertise in managing bipolar disorders were provided with 14 questions addressing nuances in managing those with a bipolar II disorder.

RESULTS

To all questions, the independently derived recommended strategies demonstrated distinct divergence.

CONCLUSION

The lack of consensus in management recommendations is likely to reflect the disorder being relatively recently formalised, the lack of condition-specific randomised controlled trial data and the nature of psychiatric practice.

Anticoagulation and Spine Surgery

STUDY DESIGN

Literature review.

OBJECTIVE

Preoperative management of therapeutic anticoagulation in spine surgery is critical to minimize risk of thromboembolic events yet prevent postsurgical complications. Limited research is available, and most guidelines are based on drug half-lives. We aim to clarify current guidelines and available evidence for safe practice of spine surgery in this patient population.

METHODS

A literature search in PubMed was done encompassing comprehensive search terms to locate published literature on anticoagulation and spine surgery. Predefined inclusion and exclusion criteria were applied and data extraction was performed.

RESULTS

A total of 17 articles met the final inclusion criteria. Of these, 12 articles were retrospective chart reviews, 3 were prospective observational studies, and 2 were systematic reviews. Current practice suggests holding warfarin until international normalized ratio <1.4, anti-Xa drugs for 48 to 72 hours, 12 to 24 hours for low-molecular-weight heparin, and 4 to 24 hours for heparin, before surgery. Antiplatelet agents can be stopped for 1 to 3 days prior to operation (81-500 mg) but must be stopped for 1 week for doses >1 g/d. For Plavix, 5 to 7 days of discontinuation advised to prevent complications.

CONCLUSIONS

This review provides an overview of main anticoagulation agents seen in preoperative setting for spine patients. Although data is mixed and no true randomized control trials are available, there is growing evidence suggesting the aforementioned guidelines are needed to optimize anticoagulation in setting of spine surgery. Further studies are needed to elucidate risk of complications while operating under therapeutic levels of anticoagulation for a variety of comorbid conditions.

Management of incidental pulmonary nodules: current strategies and future perspectives

Introduction: Detection and characterization of pulmonary nodules is an important issue, because the process is the first step in the management of lung cancers.Areas covered: Literature review was performed on May 15 2019 by using the PubMed, US National Library of Medicine National Institutes of Health, and the National Center for Biotechnology information. CT features helping identify the druggable mutations and predict the prognosis of malignant nodules were presented. Technical advancements in MRI and PET/CT were introduced for providing functional information about malignant nodules. Advances in various tissue biopsy techniques enabling molecular analysis and histologic diagnosis of indeterminate nodules were also presented. New techniques such as radiomics, deep learning (DL) technology, and artificial intelligence showing promise in differentiating between malignant and benign nodules were summarized. Recently, updated management guidelines for solid and subsolid nodules incidentally detected on CT were described. Risk stratification and prediction models for indeterminate nodules under active investigation were briefly summarized.Expert opinion: Advancement in CT knowledge has led to a better correlation between CT features and genomic alterations or tumor histology. Recent advances like PET/CT, MRI, radiomics, and DL-based approach have shown promising results in the characterization and prognostication of pulmonary nodules.

Family still matters: Counseling patients with complex family histories of colon and endometrial cancers

Background

There are no national guidelines for the management of patients with a family history consistent with Lynch syndrome (LS) but a negative genetic test. To determine current management practices, genetic counselors’ (GCs) recommendations were assessed.

Methods

A survey of GCs using five hypothetical pedigrees was posted to National Society of Genetic Counselors (NSGC) discussion forums. Descriptive statistics were used.

Results

One‐hundred and fifteen surveys were completed. A pedigree with a first‐degree relative (FDR) with early‐onset colorectal cancer (CRC) and a family history of CRC and endometrial cancer (EC) prompted 83% (n = 95) of respondents to recommend early and frequent colonoscopies, based on family history. When the CRCs and ECs occurred in family members removed from the proband, 96% (n = 110) of GCs said they would screen based on family history. However, only 52% (n = 60) suggested CRC screening should begin earlier and occur more often, and 43% (n = 50) suggested CRC screening should follow standard age and frequency guidelines.

Conclusion

Concordance of opinion among GCs for the management of patients with negative genetic test results exists when FDRs are affected. However, when affected relatives are more distant, GCs disagreed on screening recommendations. These data suggest a need for guidelines for patients with a family history of cancer and a negative genetic test.

Costello syndrome: Clinical phenotype, genotype, and management guidelines

Costello syndrome (CS) is a RASopathy caused by activating germline mutations in HRAS. Due to ubiquitous HRAS gene expression, CS affects multiple organ systems and individuals are predisposed to cancer. Individuals with CS may have distinctive craniofacial features, cardiac anomalies, growth and developmental delays, as well as dermatological, orthopedic, ocular, and neurological issues; however, considerable overlap with other RASopathies exists. Medical evaluation requires an understanding of the multifaceted phenotype. Subspecialists may have limited experience in caring for these individuals because of the rarity of CS. Furthermore, the phenotypic presentation may vary with the underlying genotype. These guidelines were developed by an interdisciplinary team of experts in order to encourage timely health care practices and provide medical management guidelines for the primary and specialty care provider, as well as for the families and affected individuals across their lifespan. These guidelines are based on expert opinion and do not represent evidence-based guidelines due to the lack of data for this rare condition.

Diagnosis and management of glycogen storage diseases type VI and IX: a clinical practice resource of the American College of Medical Genetics and Genomics (ACMG)

PURPOSE

Glycogen storage disease (GSD) types VI and IX are rare diseases of variable clinical severity affecting primarily the liver. GSD VI is caused by deficient activity of hepatic glycogen phosphorylase, an enzyme encoded by the PYGL gene. GSD IX is caused by deficient activity of phosphorylase kinase (PhK), the enzyme subunits of which are encoded by various genes: ɑ (PHKA1, PHKA2), β (PHKB), ɣ (PHKG1, PHKG2), and δ (CALM1, CALM2, CALM3). Glycogen storage disease types VI and IX have a wide spectrum of clinical manifestations and often cannot be distinguished from each other, or from other liver GSDs, on clinical presentation alone. Individuals with GSDs VI and IX can present with hepatomegaly with elevated serum transaminases, ketotic hypoglycemia, hyperlipidemia, and poor growth. This guideline for the management of GSDs VI and IX was developed as an educational resource for health-care providers to facilitate prompt and accurate diagnosis and appropriate management of patients.

METHODS

A national group of experts in various aspects of GSDs VI and IX met to review the limited evidence base from the scientific literature and provided their expert opinions. Consensus was developed in each area of diagnosis, treatment, and management. Evidence bases for these rare disorders are largely based on expert opinion, particularly when targeted therapeutics that have to clear the US Food and Drug Administration (FDA) remain unavailable.

RESULTS

This management guideline specifically addresses evaluation and diagnosis across multiple organ systems involved in GSDs VI and IX. Conditions to consider in a differential diagnosis stemming from presenting features and diagnostic algorithms are discussed. Aspects of diagnostic evaluation and nutritional and medical management, including care coordination, genetic counseling, and prenatal diagnosis are addressed.

CONCLUSION

A guideline that will facilitate the accurate diagnosis and optimal management of patients with GSDs VI and IX was developed. This guideline will help health-care providers recognize patients with GSDs VI and IX, expedite diagnosis, and minimize adverse sequelae from delayed diagnosis and inappropriate management. It will also help identify gaps in scientific knowledge that exist today and suggest future studies.

Deep Vein Thrombosis in Acute Stroke - A Systemic Review of the Literature

We present a systemic review of available literature on the complications of deep venous thrombosis that develops in patients presenting with acute stroke. There are several pharmacological and physical treatment options available and used. We aim to summarize the management plans currently used at different centers. In conclusion, low-dose anticoagulant therapy for ischemic stroke is recommended. In the case of intracerebral hemorrhage, pneumatic sequential compression devices should be placed initially, followed by the administration of ultra-fractioned heparin on the next day, and then oral anticoagulant therapy to replace the heparin after a week in high-risk patients. Similar prophylactic treatment recommendations are used for subarachnoid hemorrhage.

ACR Thyroid Imaging, Reporting and Data System (TI-RADS): White Paper of the ACR TI-RADS Committee

classification that is widely used in breast imaging, their authors chose to apply the acronym TI-RADS, for Thyroid Imaging, Reporting and Data System. In 2012, the ACR convened committees to (1) provide recommendations for reporting incidental thyroid nodules, (2) develop a set of standard terms (lexicon) for ultrasound reporting, and (3) propose a TI-RADS on the basis of the lexicon. The committees published the results of the first two efforts in 2015. In this article, the authors present the ACR TI-RADS Committee's recommendations, which provide guidance regarding management of thyroid nodules on the basis of their ultrasound appearance. The authors also describe the committee's future directions.

Surveillance and management of patients with tuberous sclerosis complex

Tuberous sclerosis complex (TSC) is an autosomal dominant disease due to the uncontrolled differentiation, proliferation, and migration of cells in several organs. Clinical expression is highly variable, from mild skin findings and asymptomatic brain lesions to seizures, mental retardation, autism, and potentially fatal kidney, cardiac, or pulmonary disease. Aim of this paper is to summarize the diagnostic criteria, surveillance and therapeutic issues of this multisystemic disorder emphasizing the most important neurological consequences. Presenting the state-of-the-art management recommendations and comparing them with the local protocols, we hope that our review might help in the proper assessment of one of the most important single gene disorder.

Addition of the Fleischner Society Guidelines to Chest CT Examination Interpretive Reports Improves Adherence to Recommended Follow-up Care for Incidental Pulmonary Nodules

RATIONALE AND OBJECTIVES

The study aimed to determine whether the addition of the Fleischner Society guidelines to chest computed tomography (CT) reports identifying incidental pulmonary nodules affects follow-up care.

PATIENTS AND METHODS

Beginning in 2008, a template containing the Fleischner Society guidelines was added at the interpreting radiologist's discretion to chest CT reports describing incidental solid pulmonary nodules at our institution. The records of all medical centers in Olmsted county were used to capture the complete medical history of local patients >35 years old diagnosed with a pulmonary nodule from April 1, 2008 to October 1, 2011. Patients with a history of cancer or previously diagnosed nodule, or who died before follow-up, were excluded. Patients were categorized according to whether they did ("template group") or did not ("control group") have the template added. Nodule size and smoking history were used to determine recommended follow-up care. Differences in follow-up were compared between groups using Pearson's chi-square test.

RESULTS

A total of 510 patients (276 in the template group, 234 in the control group) were included in the study. Only 198 patients (39%) received their recommended follow-up care. Template group patients were significantly more likely to receive recommended follow-up care compared to control group patients (45% vs 31%, P = .0014). Most patients whose management did not adhere to Fleischner Society guidelines did not receive a recommended follow-up chest CT (210 out of 312, 67%).

CONCLUSIONS

The addition of the Fleischner Society guidelines to chest CT reports significantly increases the likelihood of receiving recommended follow-up care for patients with incidental pulmonary nodules. Additional education is needed to improve appropriate guideline utilization by radiologists and adherence by ordering providers.

Low adherence of HIV providers to practice guidelines for hepatocellular carcinoma screening in HIV/hepatitis B coinfection

BACKGROUND

In the era of combination therapy for human immunodeficiency virus (HIV), liver disease, and hepatocellular carcinoma (HCC) are major causes of death for patients coinfected with HIV and hepatitis B virus (HBV). This study compared HIV provider and hepatologist awareness of and adherence to the American Association for the Study of Liver Diseases (AASLD) practice guidelines for chronic HBV management. The primary endpoint of HIV provider adherence to HCC screening recommendations was compared to that of hepatologists at a large metropolitan academic medical center.

METHODS

Medical record database searches by ICD-9 codes were used to identify HIV/HBV coinfected (n = 144) and HBV monoinfected (n = 225) patients who were seen at least twice over a 2-year period in outpatient clinics. Adherence to AASLD guidelines was assessed by chart review. Provider awareness was evaluated through a voluntary anonymous survey with knowledge-based questions.

RESULTS

Over a 2-year period, only 36.0% of HIV/HBV coinfected patients seen in HIV practices completed HCC screening compared to 81.8% of HBV monoinfected patients in hepatology practices (P < .00001). Similarly, HIV providers less frequently monitored HBV viral load (P < .0001), HBeAg/anti-HBe (P < .00001), HBsAg/anti-HBs (P < .00001) than hepatologists but screened more often for hepatitis A immunity (P = .028). Self-reported adherence and knowledge scores were similar among 19 HIV providers and 16 hepatologists.

CONCLUSIONS

HIV providers ordered significantly fewer HCC screening and HBV monitoring tests than hepatologists within a single academic medical center. In the setting of increased reliance on quality indicators for care, both patients and providers will benefit from greater adherence to established guidelines.

Cardio-facio-cutaneous syndrome: clinical features, diagnosis, and management guidelines

Cardio-facio-cutaneous syndrome (CFC) is one of the RASopathies that bears many clinical features in common with the other syndromes in this group, most notably Noonan syndrome and Costello syndrome. CFC is genetically heterogeneous and caused by gene mutations in the Ras/mitogen-activated protein kinase pathway. The major features of CFC include characteristic craniofacial dysmorphology, congenital heart disease, dermatologic abnormalities, growth retardation, and intellectual disability. It is essential that this condition be differentiated from other RASopathies, as a correct diagnosis is important for appropriate medical management and determining recurrence risk. Children and adults with CFC require multidisciplinary care from specialists, and the need for comprehensive management has been apparent to families and health care professionals caring for affected individuals. To address this need, CFC International, a nonprofit family support organization that provides a forum for information, support, and facilitation of research in basic medical and social issues affecting individuals with CFC, organized a consensus conference. Experts in multiple medical specialties provided clinical management guidelines for pediatricians and other care providers. These guidelines will assist in an accurate diagnosis of individuals with CFC, provide best practice recommendations, and facilitate long-term medical care.

The International Society of Pediatric and Adolescent Diabetes guidelines for management of diabetic ketoacidosis: Do the guidelines need to be modified?

The current version of the International Society of Pediatric and Adolescent Diabetes (ISPAD) guidelines for management of diabetic ketoacidosis (DKA) is largely based on the Lawson Wilkins Pediatric Endocrine Society/European Society of Pediatric Endocrinology (LWPES/ESPE) consensus statement on DKA in children and adolescents published in 2004. This article critically reviews and presents the most pertinent new data published in the past decade, which have implications for diagnosis and management. Four elements of the guidelines warrant modification: (i) The definition of DKA; (ii) insulin therapy; (iii) water and salt replacement; and (iv) blood ß-hydroxybutyrate measurements for the management of DKA.

Changing clinical practice: management of paediatric community-acquired pneumonia

RATIONALE AND AIM

To compare clinical features and management of paediatric community-acquired pneumonia (PCAP) following the publication of UK pneumonia guidelines in 2002 with data from a similar survey at the same hospitals in 2001-2002 (pre-guidelines).

METHODS

A prospective survey of 11 hospitals in Northern England was undertaken during 2008-2009. Clinical and laboratory data were recorded on children aged ≤16 years who presented with clinical and radiological features of pneumonia.

RESULTS

542 children were included. There was a reduction in all investigations performed (P < 0.001) except C-reactive protein (P = 0.448) between surveys. These included full blood count (76% to 61%); blood culture (70% to 53%) and testing of respiratory secretions for viruses (24% to 12%) and bacteria (18% to 8%). Compared to pre-guidelines, there was a reduction in the use of intravenous antibiotics as a proportion of the total prescribed from 47% to 36% (P < 0.001) and a change in the route of antibiotic administration with increasing preference for oral alone (16% pre-compared to 50% post-guidelines, P < 0.001).

CONCLUSION

Apart from the acute phase reactants that should not be measured routinely, these changes are in line with the guideline recommendations. Improvements in antibiotic use are possible and have implications for future antimicrobial stewardship programmes. Further work using cost-effectiveness analysis may also demonstrate a financial benefit to health services from adoption of guidelines.

Adherence to management guidelines for growth faltering and anaemia in remote dwelling Australian Aboriginal infants and barriers to health service delivery

BACKGROUND

Remote dwelling Aboriginal infants from northern Australia have a high burden of disease and frequently use health services. Little is known about the quality of infant care provided by remote health services. This study describes the adherence to infant guidelines for anaemia and growth faltering by remote health staff and barriers to effective service delivery in remote settings.

METHODS

A mixed method study drew data from 24 semi-structured interviews with clinicians working in two remote communities in northern Australia and a retrospective cohort study of Aboriginal infants from these communities, born 2004-2006 (n = 398). Medical records from remote health centres were audited. The main outcome measures were the period prevalence of infants with anaemia and growth faltering and management of these conditions according to local guidelines. Qualitative data assessed clinicians' perspectives on barriers to effective remote health service delivery.

RESULTS

Data from 398 health centre records were analysed. Sixty eight percent of infants were anaemic between six and twelve months of age and 42% had documented growth faltering by one year. Analysis of the growth data by the authors however found 86% of infants experienced growth faltering over 12 months. Clinical management and treatment completion was poor for both conditions. High staff turnover, fragmented models of care and staff poorly prepared for their role were barriers perceived by clinicians' to impact upon the quality of service delivery.

CONCLUSION

Among Aboriginal infants in northern Australia, malnutrition and anaemia are common and occur early. Diagnosis of growth faltering and clinicians' adherence to management guidelines for both conditions was poor. Antiquated service delivery models, organisation of staff and rapid staff turnover contributed to poor quality of care. Service redesign, education and staff stability must be a priority to redress serious deficits in quality of care provided for these infants.

Nonvestibular schwannoma tumors in the cerebellopontine angle: a structured approach and management guidelines

The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma, but one in five CPA tumors are not vestibular schwannomas. These tumors may require different management strategies. Compared with vestibular schwannomas, symptoms and signs from cranial nerve VIII are less frequent: other cranial nerve and cerebellar symptoms and signs predominate in patients with these less common CPA tumors. Computed tomography and magnetic resonance imaging often show features leading to the correct diagnosis. Treatment most often includes surgery, but a policy of observation or subtotal resection is often wiser. This review provides a structured approach to the diagnosis of nonvestibular schwannoma CPA lesions and also management guidelines.
