    A "Hot Cross Bun" sign on T2-weighted MRI was described as a result of selective loss of myelinated transverse pontocerebellar fibers and neurons in the pontine raphe with preservation of the pontine tegmentum and corticospinal tracts (CST). However, neuropathologic studies showed contradicting results with no sparing of the CST. This is a pictorial and quantitative demonstration of the sign on diffusion tensor imaging and tractography, which provides the imaging evidence that is consistent with neuropathologic findings.

    Background: Atopic dermatitis (AD) is a common skin condition among Asians. Recent studies have shown that Asian AD has a unique clinical and immunologic phenotype compared with European/American AD.

    Objective: The Asian Academy of Dermatology and Venereology Expert Panel on Atopic Dermatitis developed this reference guide to provide a holistic and evidence-based approach in managing AD among Asians.

    Methods: Electronic searches were performed to retrieve relevant systematic reviews and guidelines on AD. Recommendations were appraised for level of evidence and strength of recommendation based on the U.K. National Institute for Health and Care Excellence and Scottish Intercollegiate Guidelines Network guidelines. These practice points were based on the consensus recommendations discussed during the Asia Pacific Meeting of Experts in Dermatology held in Bali, Indonesia in October 2016 and April 2017.

    Results: The Expert Panel recommends an approach to treatment based on disease severity. The use of moisturizers is recommended across all levels of AD severity, while topical steroids are recommended only for flares not controlled by conventional skin care and moisturizers. Causes of waning efficacy must be explored before using topical corticosteroids of higher potency. Topical calcineurin inhibitors are recommended for patients who have become recalcitrant to steroid, in chronic uninterrupted use, and when there is steroid atrophy, or when there is a need to treat sensitive areas and pediatric patients. Systemic steroids have a limited role in AD treatment and should be avoided if possible. Educational programs that allow a patient-centered approach in AD management are recommended as an adjunct to conventional therapies. Recommendations on the use of phototherapy, systemic drugs, and emerging treatments are also included.

    Conclusion: The management of AD among Asians requires a holistic approach, integrating evidence-based treatments while considering accessibility and cultural acceptability.

    OBJECTIVE: To develop a decision tree based on standard magnetic resonance imaging (MRI) and diffusion tensor imaging to differentiate multiple system atrophy (MSA) from Parkinson's disease (PD).

    METHODS: 3-T brain MRI and DTI (diffusion tensor imaging) were performed on 26 PD and 13 MSA patients. Regions of interest (ROIs) were the putamen, substantia nigra, pons, middle cerebellar peduncles (MCP) and cerebellum. Linear, volumetry and DTI (fractional anisotropy and mean diffusivity) were measured. A three-node decision tree was formulated, with design goals being 100 % specificity at node 1, 100 % sensitivity at node 2 and highest combined sensitivity and specificity at node 3.

    RESULTS: Nine parameters (mean width, fractional anisotropy (FA) and mean diffusivity (MD) of MCP; anteroposterior diameter of pons; cerebellar FA and volume; pons and mean putamen volume; mean FA substantia nigra compacta-rostral) showed statistically significant (P < 0.05) differences between MSA and PD with mean MCP width, anteroposterior diameter of pons and mean FA MCP chosen for the decision tree. Threshold values were 14.6 mm, 21.8 mm and 0.55, respectively. Overall performance of the decision tree was 92 % sensitivity, 96 % specificity, 92 % PPV and 96 % NPV. Twelve out of 13 MSA patients were accurately classified.

    CONCLUSION: Formation of the decision tree using these parameters was both descriptive and predictive in differentiating between MSA and PD.

    KEY POINTS: • Parkinson's disease and multiple system atrophy can be distinguished on MR imaging. • Combined conventional MRI and diffusion tensor imaging improves the accuracy of diagnosis. • A decision tree is descriptive and predictive in differentiating between clinical entities. • A decision tree can reliably differentiate Parkinson's disease from multiple system atrophy.

    A 2-year-old girl who was under genetic follow up for developmental delay and dysmorphism was accidentally found to have bilateral optic disc swelling during screening examination. She showed response to optokinetic drum examination and the anterior segment examination was unremarkable. Optic disc swellings were seen in both eyes. Lumbar puncture shows high opening pressure of 50 cm H2O with unremarkable CSF analysis. MRI of brain was done and showed features in keeping with mild cerebral atrophy, with no evidence of hydrocephalus or space oc- cupying lesion. She was diagnosed with idiopathic intracranial hypertension and oral acetazolamide 125mg bd was commenced. However, papilloedema persist despite medical therapy. Ventriculoperitonel shunt was inserted to re- duce the csf pressure. This case report highlights the importance of considering idiopathic intracranial hypertension as a cause of optic disc swelling in pre-pubertal children because delay in diagnosis and treatment may permanently affect visual function especially in children.

    Lipoatrophic panniculitis is a rare condition affecting mainly children, often associated with connective tissue disease. We report a healthy 12-month-old girl with no clinical or laboratory features of connective tissue disease who presented with the progressive appearance of annular atrophic plaques beginning at the left arm. A histopathological analysis revealed lobular panniculitis, with fat necrosis and an associated inflammatory infiltrate supporting the diagnosis of lipoatrophic panniculitis. Lipoatrophic panniculitis should be considered in infants and young children with clinical features of panniculitis and fat atrophy even without clinical or serologic evidence of connective tissue disease.

    Genetic diagnosis of spinal muscular atrophy (SMA) is complicated by the presence of SMN2 gene as majority of SMA patients show absence or deletion of SMN1 gene. PCR may amplify both the genes non selectively in presence of high amount of DNA. We evaluated whether allele-specific PCR for diagnostic screening of SMA is reliable in the presence of high amount of genomic DNA, which is commonly used when performing diagnostic screening using restriction enzymes.

    OBJECTIVE: The aim of this overview was to evaluate the effectiveness of phytoestrogens on vaginal health and dyspareunia in peri- and post-menopausal women.

    MATERIAL AND METHODS: Three databases including MEDLINE, Scopus and the Cochrane Central Register of Controlled Trials were from inception to August 2017.

    RESULT: Two systematic reviews and 11 RCTs were included in the overview. According to the findings, isoflavones increased the maturation value and attenuated the vaginal atrophy in the post-menopausal women. Topical isoflavones had beneficial effects on the vaginal atrophy. Similar efficacy was found in Pueraria mirifica and conjugated estrogen cream on dryness ( p = 0.277), soreness ( p = 0.124) and irritation ( p = 0.469), as well as discharge ( p = 0.225) and dyspareunia ( p = 0.089). However, the conjugated estrogen cream was more effective compared to Pueraria mirifica ( p > 0.005) regarding maturation index improvement. Comparison of fennel 5% vaginal cream and placebo gel showed significant difference in superficial cells ( p

    In Malaysia, Spinal Muscular Atrophy (SMA) is diagnosed based on clinical observation with or without muscle biopsy. Molecular analyses of the SMA-related genes have not been available so far. In this preliminary study, we searched for homozygous deletion of Survival Motor Neuron (SMN1) and Neuronal Apoptosis Inhibitory Protein (NAIP) genes in Malay patients with SMA and found homozygous deletion of SMN1 exon 7 and 8 in all the patients while homozygous deletion of NAIP exon 5 was detected in only our type 1 patients but not in the type 3 patient. To the best of our knowledge, these are the first SMA cases diagnosed at the molecular level in Malaysia.

    Apoptosis is a programmed cell death which occurs following a variety of stimuli. Physiologically the process is important for morphogenesis of organs and homeostasis of different types of cells. Apoptotic cell death is responsible for a variety of pathologic states such as elimination of cell death in mutated cells, infected cells, tumour cells and transplant rejection well as the pathological atrophy. In this review, there is discussion about the control of apoptosis, detection methods of apoptosis, its association with infectious and non-communicable diseases. Intracellular microorganisms survive through inhibition of host cell apoptosis as well as they destroy the parenchymal cells causing impaired functions. It plays important role in tumourigenesis. There are possible therapeutic roles of drugs that modify apoptosis in human diseases.

    Morphological and neuroelectrical changes of the skeletal muscle fibres after various types of injury to the nerve was studied in monkey. The percentage of normal and atrophic muscle fibres after various types of injury to the nerve was compared with the proportion of innervated and denervated muscle as shown by the position of the bend (kink) on the I.D. at corresponding stages. It was found that the pattern and the position of the I.D. curve when considered together only gave an approximate estimation of the proportion of all innervated and denervated muscle fibres as well as the condition ofthe muscle after denervation.

    Phytochemical contents of honey are presumed to be beneficial to the female reproductive system (FRS). However, the biological effects of honey supplementation (HS) in vivo on the FRS remain unclear. This review aims to investigate the current literature on the effects of HS on the FRS, particularly on the sex hormone profile and reproductive organs (uterus and vagina). A systematic literature search using Scopus, MEDLINE via Ovid and Cochrane Library databases was conducted. Records were screened and identified for preclinical and clinical studies addressing the effects of HS on the FRS. Data on populations, interventions, outcomes and methodological quality were extracted. Studies were synthesised using tables and written summaries. Of the 198 identified records, six fulfilled the inclusion criteria. All six records were used for data extraction: two experimental studies using rats as the model organism and four human clinical studies of honey on female reproductive health. HS elevated the progesterone levels, restrained body weight increase, prevented uterine and vaginal atrophies in ovariectomised rats, attenuated symptoms of candidiasis and improved oxidative status in patients. Current evidence shows that short-term HS following surgical or physiological menopause exerts an oestrogenic, antioxidant and anti-inflammatory effect on the FRS. However, insufficient long-term studies preclude any definitive conclusions.

    Posterior Segment Eye Diseases (PSED) namely Diabetic Retinopathy (DR), glaucoma and Age-related Macular Degeneration (AMD) are the prime causes of vision loss globally. Vision loss can be prevented, if these diseases are detected at an early stage. Structural abnormalities such as changes in cup-to-disc ratio, Hard Exudates (HE), drusen, Microaneurysms (MA), Cotton Wool Spots (CWS), Haemorrhages (HA), Geographic Atrophy (GA) and Choroidal Neovascularization (CNV) in PSED can be identified by manual examination of fundus images by clinicians. However, manual screening is labour-intensive, tiresome and time consuming. Hence, there is a need to automate the eye screening. In this work Bi-dimensional Empirical Mode Decomposition (BEMD) technique is used to decompose fundus images into 2D Intrinsic Mode Functions (IMFs) to capture variations in the pixels due to morphological changes. Further, various entropy namely Renyi, Fuzzy, Shannon, Vajda, Kapur and Yager and energy features are extracted from IMFs. These extracted features are ranked using Chernoff Bound and Bhattacharyya Distance (CBBD), Kullback-Leibler Divergence (KLD), Fuzzy-minimum Redundancy Maximum Relevance (FmRMR), Wilcoxon, Receiver Operating Characteristics Curve (ROC) and t-test methods. Further, these ranked features are fed to Support Vector Machine (SVM) classifier to classify normal and abnormal (DR, AMD and glaucoma) classes. The performance of the proposed eye screening system is evaluated using 800 (Normal=400 and Abnormal=400) digital fundus images and 10-fold cross validation method. Our proposed system automatically identifies normal and abnormal classes with an average accuracy of 88.63%, sensitivity of 86.25% and specificity of 91% using 17 optimal features ranked using CBBD and SVM-Radial Basis Function (RBF) classifier. Moreover, a novel Retinal Risk Index (RRI) is developed using two significant features to distinguish two classes using single number. Such a system helps to reduce eye screening time in polyclinics or community-based mass screening. They will refer the patients to main hospitals only if the diagnosis belong to the abnormal class. Hence, the main hospitals will not be unnecessarily crowded and doctors can devote their time for other urgent cases.

    Cerebral lupus (CL) is a common cause of morbidity and mortality in patients with SLE. The brain CTs of 27 consecutive adult patients with SLE and various neurological presentations were reviewed. The median age and duration of neurological symptoms at the time of the brain CT were 30 years (range = 14-51 years) and six days (range = 1 day-22 years), respectively. Eleven patients (41%) had normal CTs. The abnormalities in the remaining patients could be divided into six categories: (a) cerebral atrophy alone (two patients); (b) calcification alone (three patients); (c) infarct(s) alone (five patients); (d) cerebral atrophy and calcification (three patients); (e) cerebral atrophy and infarct(s) (one patient) and (f) cerebral atrophy, calcification and infarct(s) (two patients). Altogether eight patients (30%) (age range = 17-47 years) had intracerebral calcification: the globus pallidus was involved in all, putamen in two, head of the caudate nucleus in one, thalamus in one, centrum semiovale in two and cerebellum in three patients. Two patients had extensive calcifications of most of the basal ganglia, centrum semiovale and cerebellum. There was no relationship between the presence/degree of calcification and age of patients/duration or type of neurological presentation. The pathogenesis of cerebral calcification in CL is unknown. Cerebral lupus must now be included in the differential diagnosis of intracerebral calcification.

    OBJECTIVE: To test the hypothesis that imaging signs of 'brain frailty' and acute ischaemia predict clinical outcomes and symptomatic intracranial haemorrhage (sICH) after thrombolysis for acute ischaemic stroke (AIS) in the alteplase dose arm of ENhanced Control of Hypertension ANd Thrombolysis strokE stuDy (ENCHANTED).

    METHODS: Blinded assessors coded baseline images for acute ischaemic signs (presence, extent, swelling and attenuation of acute lesions; and hyperattenuated arteries) and pre-existing changes (atrophy, leucoaraiosis and old ischaemic lesions). Logistic regression models assessed associations between imaging features and death at 7 and 90 days; good recovery (modified Rankin Scale scores 0-2 at 90 days) and sICH. Data are reported with adjusted ORs and 95% CIs.

    RESULTS: 2916 patients (67±13 years, National Institutes of Health Stroke Scale 8 (5-14)) were included. Visible ischaemic lesions, severe hypoattenuation, large ischaemic lesion, swelling and hyperattenuated arteries were associated with 7-day death (OR (95% CI): 1.52 (1.06 to 2.18); 1.51 (1.01 to 2.18); 2.67 (1.52 to 4.71); 1.49 (1.03 to 2.14) and 2.17 (1.48 to 3.18)) and inversely with good outcome. Severe atrophy was inversely associated with 7-day death (0.52 (0.29 to 0.96)). Atrophy (1.52 (1.08 to 2.15)) and severe leucoaraiosis (1.74 (1.20 to 2.54)) were associated with 90-day death. Hyperattenuated arteries were associated with sICH (1.71 (1.01 to 2.89)). No imaging features modified the effect of alteplase dose.

    CONCLUSIONS: Non-expert-defined brain imaging signs of brain frailty and acute ischaemia contribute to the prognosis of thrombolysis-treated AIS patients for sICH and mortality. However, these imaging features showed no interaction with alteplase dose.

    Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by mutations in the SMN1 gene. The SMN2 gene is highly homologous to SMN1 and has been reported to be correlated with severity of the disease. The clinical presentation of SMA varies from severe to mild, with three clinical subtypes (type I, type II, and type III) that are assigned according to age of onset and severity of the disease. Here, we aim to investigate the potential association between the number of copies of SMN2 and the deletion in the NAIP gene with the clinical severity of SMA in patients of Malaysian origin. Forty-two SMA patients (14 of type I, 20 type II, and 8 type III) carrying deletions of the SMN1 gene were enrolled in this study. SMN2 copy number was determined by fluorescence-based quantitative polymerase chain reaction assay. Twenty-nine percent of type I patients carried one copy of SMN2, while the remaining 71% carried two copies. Among the type II and type III SMA patients, 29% of cases carried two copies of the gene, while 71% carried three or four copies of SMN2. Deletion analysis of NAIP showed that 50% of type I SMA patients had a homozygous deletion of exon 5 of this gene and that only 10% of type II SMA cases carried a homozygous deletion, while all type III patients carried intact copies of the NAIP gene. We conclude that there exists a close relationship between SMN2 copy number and SMA disease severity, suggesting that the determination of SMN2 copy number may be a good predictor of SMA disease type. Furthermore, NAIP gene deletion was found to be associated with SMA severity. In conclusion, combining the analysis of deletion of NAIP with the assessment of SMN2 copy number increases the value of this tool in predicting the severity of SMA.

    We report a 35 year-old Iranian female who presented with a sudden onset of left sided hemiparesis associated with temporary loss of consciousness of about 3 minutes. Neurological examination revealed a power of 0/5 over the left upper/lower limbs but reflexes were normal and plantar reflex was downgoing and equivocal. A computed tomography scan was done and it revealed mild bilateral frontal atrophy and a temporal arachnoid cyst which was decidedly an incidental finding and it did not have any relation to the clinical presentation. Electroencephalogram and other laboratory findings were all normal. When the psychiatric team interviewed her, it was revealed that the patient had recently experienced a major stressful event just prior to the hemiparesis. On further interview, the patient had complained of delusions of persecution, delusions of reference and also auditory hallucinations for approximately a year prior to admission. There have been only a spatter of reports of conversion symptoms seen in patients with schizophrenia and this is such a case.

    Cutis marmorata telangiectatica congenita is characterized by the presence of a bluish-purple reticulated cutaneous vascular network on the skin intermixed with telangiectasia and occasionally prominent veins at birth. Areas of the skin within the reticulated cutaneous vascular network may be normal, erythematous, atrophic, and, at times, ulcerated. Areas of ulcerations and focal cutaneous and subcutaneous atrophy occasionally occur resulting in body asymmetry. On the other hand, cutaneous and subcutaneous atrophy, extensive and severe enough leading to hemiatrophy, of the entire limb is rare. A search of the English literature revealed only eight documented cases to which we are adding two more cases.

    The authors suggest a simplification for the current molecular genetic testing of spinal muscular atrophy (SMA). Deletion analysis of SMN1 exon 7 alone may be necessary and sufficient for the diagnosis of SMA. It is based on sole contribution of survival motor neuron 1 (SMN1) exon 7 to SMA pathogenesis.
