Anorexia Nervosa is one of the eating disorders, as classified in the Diagnostic and Statistical Manual, the fifth edition. It is characterised by a pathological fear of weight gain associated
with an overwhelming drive for thinness. Patients do present to primary care with vague, non-specific complaints. A heightened degree of suspicion is required for the diagnosis, as patients tend to hide symptoms and are often in denial. We present a case in an 11-year-old girl brought by her mother to the polyclinic with a history of restrictive eating and excessive
exercise for three weeks. This case provided a learning opportunity on the assessment and management of an eating disorder, as well as the adverse effects of undernutrition.

Purpose:
We aimed to identify the anterolateral ligament (ALL) tears in anterior cruciate ligament (ACL)-deficient knees using standard 1.5-Tesla magnetic resonance imaging (MRI).
Methods:
We included all patients who underwent primary ACL reconstruction at our center between 2012 and 2015. Exclusion criteria included patients with multiple ligament injuries, lateral collateral ligament, posterolateral corner, and infections, and patients who underwent MRI more than 2 months after their injury. All patients (n = 148) had ACL tears that were subsequently arthroscopically reconstructed. The magnetic resonance (MR) images of the injured knees performed within 2 months of injury were reviewed by a musculoskeletal radiologist and an orthopedic surgeon. The patients were divided into two groups. The first group of patients had MRI performed within 1 month of injury. The second group of patients had MRI performed 1–2 months after the index injury. Both assessors were blinded and the MR mages were read separately to assess the presence of ALL, presence of a tear and the location of the tear. Based on their readings, interobserver agreement (kappa statistic (K)), sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were compared.
Results:
The ALL was identified in 100% of the patients. However, there was a discrepancy of up to 15% in the identification of tear of the ALL. In the first group in which MRI scans were performed within 1 month of injury, the ALL tear was identified by the radiologist in 92% of patients and by the surgeon in 90% of patients (Κ = 0.86). In the second group in which MRI scans were performed within 1–2 months of the injury, the ALL tear was identified by the radiologist in 78% of patients and by the surgeon in 93% of patients (K = 0.62).
Conclusion
The ALL can be accurately identified on MRI, but the presence and location of ALL tear and its location cannot be reliably identified on MRI. The accuracy in identification and characterization of a tear was affected by the interval between the time of injury and the time when the MRI was performed.Level of evidence: Diagnostic, level IIIb, retrospective.

INTRODUCTIONThis is the fi rst prospective study done locally to determine the effectiveness of vacuum-assisted closure (VAC) therapy in the healing of chronic diabetic foot ulcers.
MATERIALS AND METHODSAn electronic vacuum pump was used to apply controlled negative pressure evenly across the wound surface. Changes in wound dimension, presence of wound granulation and infection status of diabetic foot ulcers in 11 consecutive patients with diabetes were followed over the course of VAC therapy.
RESULTSHealing was achieved in all wounds. Nine wounds were closed by split-skin grafting and 2 by secondary closure. The average length of treatment with VAC therapy was 23.3 days. Ten wounds showed reduction in wound size. All wounds were satisfactorily granulated and cleared of bacterial infection at the end of VAC therapy.
CONCLUSIONSVAC therapy was useful in the treatment of diabetic foot infection and ulcers, which after debridement, may present with exposed tendon, fascia and/or bone. These included ray amputation wounds, wounds post-debridement for necrotising fasciitis, wounds post-drainage for abscess, a heel ulcer and a sole ulcer. It was able to prepare ulcers well for closure via split-skin grafting or secondary closure in good time. This reduced cost of VAC therapy, as therapy was not prolonged to attain greater reduction in wound area. VAC therapy also provides a sterile, more controlled resting environment to large, exudating wound surfaces. Large diabetic foot ulcers were thus made more manageable.

INTRODUCTION:
Frailty is associated with adverse health outcomes and can be measured using the FRAIL scale. In Singapore, its use has been studied in tertiary hospitals but not in community hospitals. A tool to predict rehabilitation outcomes would allow for better risk stratification and allocation of resources. We aimed to determine whether the FRAIL scale is associated with rehabilitation outcomes in patients admitted to the community hospital setting, where post-acute care and rehabilitation are primarily delivered.
METHODS:
This was a retrospective cohort study. The FRAIL scale was utilised to screen 560 older adults who were admitted to a community hospital for rehabilitation. Data were analysed to determine the relationship between baseline characteristics and frailty status, with rehabilitation outcome measures of absolute functional gain, rehabilitation effectiveness, rehabilitation efficiency, length of stay and discharge destination.
RESULTS:
The combined score of the FRAIL scale showed significant negative association with absolute functional gain (P < 0.001), rehabilitation effectiveness (P < 0.001) and rehabilitation efficiency (P < 0.001), whereas it was positively associated with increased length of stay (P < 0.05) and a need for continued support in increased care settings (P < 0.001). Individual components of the FRAIL scale, in particular, the 'fatigue', 'ambulation' and 'loss of weight' components, appeared to be highly associated with rehabilitation effectiveness and efficiency, especially among pre-frail patients.
CONCLUSION
The utility of the FRAIL scale as an indicator of frailty status and its association with rehabilitative outcomes in the post-acute care setting were demonstrated. Moreover, the FRAIL scale may better predict the rehabilitative progress of pre-frail patients.

INTRODUCTIONEnterovirus infections in childhood can be associated with significant neurological morbidity. This study aimed to describe the prevalence and range of neurological manifestations, determine the clinical characteristics and assess differences in clinical outcomes for Singaporean children diagnosed with enterovirus infections.
METHODSIn this single-centre, case-control study, clinical data was collected retrospectively from patients admitted to National University Hospital, Singapore, from August 2007 to October 2011 and diagnosed with enterovirus infection, based on the enterovirus polymerase chain reaction test, or cultures from throat and rectal swabs or cerebrospinal fluid samples. The occurrence of neurological manifestations was reviewed and clinical outcomes were assessed.
RESULTSA total of 48 patients (age range: six days-17.8 years) were included in the study. Neurological manifestations were seen in 75.0% of patients, 63.9% of whom presented with aseptic meningitis. Other neurological manifestations included encephalitis, acute cerebellitis, transverse myelitis and autonomic dysfunction. The incidence of neurological manifestations was significantly higher in patients aged > 1 year as compared to younger patients (p = 0.043). In patients without neurological manifestations, a significantly higher proportion presented with hand, foot and mouth disease and poor feeding. Long-term neurological sequelae were seen in 16.7% of patients with neurological manifestations.
CONCLUSIONA wide spectrum of neurological manifestations resulting in a relatively low incidence of long-term neurological sequelae was observed in our study of Singaporean children with enterovirus infections. As some of these neurological morbidities were severe, careful evaluation of children with neurological involvement is therefore necessary.
