Abstract
Abstract
Introduction
The gold standard for treatment of Obstructive sleep apnea (OSA) is continuous positive airway pressure (CPAP). However, CPAP adherence is less than 50%. An alternative treatment is the hypoglossal nerve stimulator (HNS) which displaces the tongue anteriorly to treat upper airway obstruction. Difficulties tolerating HNS are related to stimulation discomfort. In this study, we investigated insomnia as a barrier to adherence.
Methods
Patients implanted and activated with HNS at The Ohio State University Wexner Medical Center between 2015 and 2019 were eligible. Patient usage data from the previous six months was obtained and subjects were asked to complete an Insomnia Severity Index (ISI). Participants were divided into adherent (defined as use ≥28 hours/week) and non-adherent (use <28 hours/week).
Results
32 subjects were enrolled, 22 in the adherent group and 10 in the non-adherent group. There was a significant decrease in mean treatment AHI in both groups: 36.25 to 11.14 in the adherent group and 36.30 to 15.69 in the non-adherent group (p<0.0001). The mean ISI score in the adherent group was 6.84 which is consistent with no clinically significant insomnia and 8.67 in the non-adherent group consistent with subthreshold insomnia. However, there was not a statistically significant difference between the two groups (p=0.441). There was a statistically significant higher score for the question “Do you worry about your sleep problems?” in the non-adherent group (1.78, SD1.39 vs 0.74. SD 0.81) (p =0.018).
Conclusion
This study suggests that patients who have difficulty with sleep may have more difficulty with HNS adherence than those who do not. In particular the question stating “Do you worry about your sleep problems” had a statistically higher score in the non-adherent group. Prospective studies are needed to further explore a possible relationship between insomnia and HNS adherence.

Abstract
The present study examines the potential of sequencing a neurocognitive intervention with behavioral parent training (BPT) to improve executive functions (EFs), psychiatric symptoms, and multiple indices of functional impairment in school-age children aged 7 to 11 years who have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Specifically, in a randomized controlled trial design, 85 children were assigned to either Cogmed Working Memory Training (CWMT) followed by an empirically supported, manualized BPT intervention, or to a placebo version of CWMT followed by the same BPT intervention. Working memory maintenance (i.e., attention control/short-term memory), working memory processing and manipulation, ADHD and oppositional defiant disorder (ODD) symptoms, impairment in parent-child dynamics, familial impairment, and overall functional compromise were evaluated as outcomes. The results suggest specific effects of the combined CWMT and BPT program on verbal and nonverbal working memory storage and nonverbal working memory processing and manipulation but no incremental benefits in regard to ADHD symptoms, ODD symptoms, and functional outcomes. The present findings do not support the hypothesis regarding the complementary and augmentative benefits of sequenced neurocognitive and BPT interventions for the treatment of ADHD. These results, the study's limitations, and future directions for research are further discussed.

Abstract
Heterotaxy syndrome with left ventricular non-compaction is a rare co-existence of abnormalities with unknown cause. It can be isolated with no other associations, or associated with congenital heart diseases, or it can occur with multiple other congenital abnormalities. We describe the third reported case of heterotaxy syndrome with left ventricular non-compaction presenting in an adult.

Abstract
BACKGROUND Surgical options for the management of early lumbosacral spondylolisthesis and degenerative disc disease with instability vary from open lumbar interbody fusion with transpedicular fixation to a variety of minimal access fusion and fixation procedures. We have used a combination of micro discectomy and axial lumbosacral interbody fusion with presacral screw fixation to treat symptomatic patients with lumbosacral spondylolisthesis or lumbosacral degenerative disc disease, which needed surgical stabilization. This study describes the above technique along with analysis of results. MATERIALS AND METHODS Twelve patients with symptomatic lumbosacral (L5-S1) instability and degenerative lumbosacral disc disease were treated by micro discectomy and interbody fusion using presacral screw stabilization. Patients with history of bowel, bladder dysfunction and local anorectal diseases were excluded from this study. Postoperatively all patients were evaluated neurologically and radiologically for screw position, fusion and stability. Oswestry disability index was used to evaluate results. RESULTS We had nine females and three males with a mean age of 47.33 years (range 26-68 years). Postoperative assessment revealed three patients to have screw placed in anterior 1/4(th) of the 1(st) sacral body, in rest nine the screws were placed in the posterior 3/4(th) of sacral body. At 2 years followup, eight patients (67%) showed evidence of bridging trabeculae at bone graft site and none of the patients showed evidence of instability or implant failure. CONCLUSION Presacral screw fixation along with micro discectomy is an effective procedure to manage early symptomatic lumbosacral spondylolisthesis and degenerative disc disease with instability.

Abstract
BACKGROUND Cogmed Working Memory Training (CWMT) has received considerable attention as a promising intervention for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in children. At the same time, methodological weaknesses in previous clinical trials call into question reported efficacy of CWMT. In particular, lack of equivalence in key aspects of CWMT (i.e., contingent reinforcement, time-on-task with computer training, parent-child interactions, supportive coaching) between CWMT and placebo versions of CWMT used in previous trials may account for the beneficial outcomes favoring CWMT. METHODS Eighty-five 7- to 11-year old school-age children with ADHD (66 male; 78%) were randomized to either standard CWMT (CWMT Active) or a well-controlled CWMT placebo condition (CWMT Placebo) and evaluated before and 3 weeks after treatment. Dependent measures included parent and teacher ratings of ADHD symptoms; objective measures of attention, activity level, and impulsivity; and psychometric indices of working memory and academic achievement (Clinical trial title: Combined cognitive remediation and behavioral intervention for the treatment of Attention-Deficit/Hyperactivity Disorder; http://clinicaltrials.gov/ct2/show/NCT01137318). RESULTS CWMT Active participants demonstrated significantly greater improvements in verbal and nonverbal working memory storage, but evidenced no discernible gains in working memory storage plus processing/manipulation. In addition, no treatment group differences were observed for any other outcome measures. CONCLUSIONS When a more rigorous comparison condition is utilized, CWMT demonstrates effects on certain aspects of working memory in children with ADHD; however, CWMT does not appear to foster treatment generalization to other domains of functioning. As such, CWMT should not be considered a viable treatment for children with ADHD.

Abstract
Moyamoya is a rare cerebrovascular disease characterised by progressive stenosis of the terminal portion of the internal carotid artery and its main branches. We report on the progression of the disease in a 3-year-old boy, confirmed to have idiopathic Moyamoya disease, over 6 ensuing years, using serial magnetic resonance imaging with MR angiography. Comparison is also made with conventional angiography at the last visit. Characteristic imaging appearances of asymmetric narrowing of the internal carotid arteries (especially the supra-clinoid portion) with numerous collateral vessels around the brainstem especially within the ambient and quadrigeminal plate cisterns are demonstrated with progression.

Abstract
OBJECTIVE To evaluate the etiology, presentation, complications and management of chronic pancreatitis in children. DESIGN Retrospective chart review. SETTING Gastroenterology department at Christian Medical College and Hospital, Vellore, India between January 2005 and December 2010. PARTICIPANTS 99 Children (>18 yrs) diagnosed with chronic pancreatitis based on clinical and imaging features. MAIN OUTCOME MEASURES Etiology, clinical presentation, complications and management of chronic pancreatitis in children. RESULTS Of 3887 children who attended the Gastroenterology department, 99(2.5%) had chronic pancreatitis, of which 60 (60.6%) were males. In 95(95.9%) patients no definite cause was detected and they were labeled as Idiopathic chronic pancreatitis. All patients had abdominal pain, while 9(9.1%) had diabetes mellitus. Of the 22 children tested for stool fat, 10(45.5%) had steatorrhea. Pancreatic calcification was seen in 69 (69.7%). 68 (71.6%) patients with idiopathic chronic pancreatitis had calcification. Calcific idiopathic chronic pancreatitis was more frequent in males (67.6% vs. 48.1%, P=0.07), and was more commonly associated with diabetes mellitus (13.2% vs. none, P=0.047) and steatorrhea (61.5% vs. 16.7%, P=0.069). Pseudocyst (17.1%) and ascites (9.1%) were the most common complications. All children were treated with pancreatic enzyme supplements for pain relief. 57 patients were followed up. With enzyme supplementation, pain relief was present in 32 (56.1%) patients. Of those who did not improve, 10 underwent endotherapy and 15 underwent surgery. Follow up of 8 patients who underwent endotherapy, showed that 5 (62.5%) had relief. Follow up of 11 patients who underwent surgery showed that only 3 (27%) had pain relief. There was no death. CONCLUSIONS Idiopathic chronic pancreatitis is the predominant form of chronic pancreatitis in children and adolescents. It can present with or without calcification. The calcific variety is an aggressive disease characterized by early morphological and functional damage to the pancreas.

Abstract
INTRODUCTION Two decades ago tropical sprue, Immunoproliferative Small Intestinal Disease (IPSID) and infections were common causes of malabsorption in India. It is possible that implementation of preventive health measures and improved sanitation may have changed the spectrum of disorders causing malabsorption. The aim of this study therefore was to assess the spectrum of malabsorption seen at our center during the past nine years. METHODOLOGY Patients seen at our center with malabsorption from January 2000 to December 2008 were included in this study. The etiological, clinical and investigation details were recorded on uniform structured data forms. The data obtained was retrospectively analyzed. RESULTS Malabsorption was detected in 124 patients during the study period. The mean age of patients was 31.9+16 years and 60.5% were males. Tropical sprue was the commonest etiology (29%) followed by celiac and Crohn's disease (15.3% each). Other important etiologies included parasitic infestations (9.7%) and immune deficiency disorders (5.6%). Intestinal tuberculosis was seen in only 2.4% patients. CONCLUSIONS We are witnessing a change in etiological spectrum of malabsorption . Celiac disease and inflammatory bowel disorders are emerging as important causes and ImmunoProliferative Small Intestinal Disease (IPSID) and intestinal tuberculosis are on the decline. Tropical Sprue however continues to be the commonest cause as in the past.

Abstract
The medical records of three children who were entrapped inside vehicles are reviewed and their outcome following the incidents were assessed in this report. The children developed heat stroke following the incidents and survived after several days in coma but with severe cognitive functions impairment. Two of the children were left with hyperactivity and attention deficit, while the third had active epilepsy.Vehicular entrapment heat stroke is one of the preventable brain injuries in children. Several children get entrapped in cars or other vehicles yearly and survivors are left with significant brain damage. The usual cause for brain damage is heat stroke the lesson learned was to never leave children unattended in cars. Therefore, it is essential to double check that doors are locked when leaving children unattended near vehicles.

Abstract
OBJECTIVES To find the incidence, clinical pattern and outcome of Guillain-Barre syndrome in the Sultanate of Oman in children less than 15 years of age. METHODS All children under fifteen years with acute flaccid paralysis were admitted to identify the underlying cause. The diagnosis of Gullain Barre syndrome was made by clinical criteria, cerebrospinal fluid findings and nerve conduction studies. Intravenous immunoglobulins were given to all and two needed plasmapharesis. RESULTS Sixty-one children were diagnosed as Guillan-Barré syndrome and constituted 20% of cases of acute flaccid paralysis. Males 39 (63.9%) outnumbered females (36.1%).The annual incidence below 15 years was 0.45/100,000. Cranial nerves were involved in 31 (50.8%) children. Albumino-cytological dissociation in cerebrospinal fluid was seen in 42/45(93.3%) cases. Acute relapse was seen in six (9.8%) cases. Eleven children (18.3%) needed ventilation. Complete recovery was seen in 45 to 310 days (mean 69.1 days). Three children (4.9%) were left with minimal residual deficit. There was no mortality. CONCLUSIONS Guillain Barre syndrome is a serious disease, although recovery is the rule in children. The disease is associated with very low mortality and long term morbidity. Immunoglobulins have reduced the duration of hospital stay and the total time needed for recovery.

Abstract
This article presents a retrospective study and a prospective study on spinal muscular atrophy in Oman. For the retrospective study, data were collected from neurophysiology records, from both inpatient and outpatient files. The prospective study was conducted on children as they presented to the hospital and was funded by Sultan Qaboos University. The patients of spinal muscular atrophy were classified into types I, II, and III based on their clinical features as per the International Spinal Muscular Atrophy Consortium classification. The incidence of spinal muscular atrophy was about 1 per 6000 live births. Spinal muscular atrophy type I formed 65% of the cases. Survival motor neuron deletion was seen in 70% of cases of all types of spinal muscular atrophy. The deletion was 83% in spinal muscular atrophy type I. A further study to look into the nondeletional cases is in progress.

Abstract
The association between severe and persistent strongyloidiasis with human T cell lymphotropic virus type I (HTLV-1) infection is well documented in reports from HTLV-1 endemic regions like Japan and Jamaica. But there are no reports from non-endemic areas like India. We report a case of severe intestinal strongyloidiasis in a 45-year old Keralite man, living in Sikkim. Despite standard treatment with many courses of albendazole, his stool persistently showed Strongyloides stercoralis larvae. In the absence of other immunosuppressive conditions, human T cell lymphotropic virus type I infection was considered and determined positive. Subsequently, treatment with 2 courses of ivermectin achieved eradication of the infection. On follow-up, 3 years later, his stools again revealed Strongyloides stercoralis larvae.

Abstract
Bortezomib (Velcade, PS341) was licensed in 2003 as a first-in-class 20S proteasome inhibitor indicated for treatment of multiple myeloma, and is currently being evaluated clinically in a range of solid tumours. The mechanisms underlying its cancer cell toxicity are complex. A growing body of evidence suggests proteasome inhibition-dependent regulation of the BCL-2 family is a critical requirement. In particular, the stabilization of BH3-only proteins BIK, NOXA and BIM, appear to be essential for effecting BAX- and BAK-dependent cell death. These mechanisms are reviewed and the implications for favourable novel drug interactions are highlighted.

Abstract
We report a 2.5-year-old girl who presented with acute history of fluctuating level of consciousness in the form of drowsiness, extreme irritability, and involuntary abnormal movements in the form of shaking of the whole body. She was treated with acyclovir empirically, contemplating herpes simplex virus encephalitis. Overtime she improved substantially. The opsoclonus, myoclonus, and ataxia disappeared without treatment. However, 6 weeks later she presented again with classic opsoclonus-myoclonus syndrome. The investigations revealed neuroblastoma. This case illustrates that transient opsoclonus-myoclonus may occur with neuroblastoma and should not be assumed to be due to viral cause. Thus, a thorough search for occult neuroblastoma should be initiated even if opsoclonus-myoclonus resolves spontaneously.

Abstract
Neuronal migrational disorders form a significant cause of psychomotor delay and intractable epilepsy in children. Pediatric neurology services are available at Sultan Qaboos University Hospital, Muscat, Oman, which is a tertiary care hospital for the whole country. The children undergoing evaluation for developmental delay and epilepsy formed the subjects of the study. Data were analyzed from children found to have neuronal migrational disorders on imaging (computed tomography [CT] or magnetic resonance imaging [MRI]). There were 40 cases of neuronal migrational disorders. Corpus callosum agenesis and lissencephaly or pachygyria formed the major group. There were 22 cases of corpus callosum agenesis, 12 of lissencephaly or pachygyria, 2 of schizencephaly, and 1 each of polymicrogyria, holoprosencephaly, hydranecephaly, and hemimegalencephaly. Nineteen of these 40 (47.5%) cases of neuronal migrational disorders had epilepsy. The break-down was 8 of 22 cases of corpus callosum agenesis (36%), 7 of 12 (58.3%) cases of lissencephaly or pachygyria, and 1 each of polymicrogyria, hydranencephaly, and hemimegalencephaly. The family history of developmental delay, similar to the index case, was present in two children with lissencephaly. However, the brain imaging did not reveal the abnormality. The types of seizures were infantile spasms in five, tonic-clonic in nine, myoclonic in two, partial in one, and mixed in five. Nineteen of 40 cases of neuronal migrational disorders had epilepsy. Only 2 of 19 (10.5%) with epilepsy had good seizure control. This raises the possibility of more and more surgical intervention in the management of such cases. Neuronal migrational disorders are related to exogenous and genetic factors from the 6th to 26th weeks of gestation. Molecular and genetic research is defining the mechanism of these disorders. This could help in early diagnosis, prevention, and eventual gene therapy in such conditions.

Abstract
Three siblings (one boy and two girls) with Brown-Vialetto-van Laere syndrome are reported. A peculiar feature of onset with hearing loss in a patient with multiple cranial nerve palsies and a positive family history suggests this diagnosis. In our family, an autosomal recessive mode of inheritance was seen. In addition, we observed that early onset was associated with rapid deterioration and death. Optic nerve involvement and hyperintensity of the brainstem nuclei on magnetic resonance imaging (MRI) are two new features described in this report.

BACKGROUND Prevalence of Crohn's disease (CD) among patients with rheumatic illnesses in India is grossly under estimated, especially when it has overtaken that of Ulcerative Colitis in the West. AIM To study the frequency of histologically unequivocal CD amongst clinically suspected patients with enteropathic arthropathy and to ascertain if the arthritics with CD have any independent clinical predictor. SETTINGS AND DESIGNS Retrospective datasheet analysis from a Rheumatology clinic of a large tertiary care centre. MATERIALS AND METHODS Patients of suspected enteropathic arthropathy were studied by ileocolonoscopy and segmental colonic biopsy for histological evidence of Crohn's disease and followed up. STATISTICAL ANALYSIS Logistic regression analysis was done to find out any clinical predictor of histologically proven CD. RESULTS Fourteen of the twenty-nine patients studied had histologically confirmed CD. Those with CD were younger than those without (34.7 yr vs 41.6 yrs, p=0.057). The CD group also had significantly higher number of people with loss of weight (12 vs 1), fever (11 vs 0), perianal fistula (4 vs 0), abdominal pain (8 vs 2), history of dysentery (4 vs 0) and uveitis (6 vs 1) (p=0.00002, 0.00001, 0.026, 0.013, 0.026 & 0.01 respectively). However logistic regression analysis of the most relevant ones among these, namely, loss of weight, fever, and perianal fistula showed loss of weight as only independent predictor of CD in this subset of patients (p=0.03 with odds ratio of 28). CONCLUSION Presence of significant loss of weight in an Indian patient with clinically suspected enteropathic arthropathy is an independent predictor of CD.

Abstract
A prospective study of Guillain-Barré syndrome from January 1992 to December 2001 was undertaken. Intravenous immunoglobulins were used in all patients. All patients were followed up until complete recovery. Various parameters, such as onset of weakness, duration of hospital stay, ventilation requirement, residual deficit, and mortality, were recorded. Acute relapses and fluctuations were also noted. The pattern of this group was compared with patients before 1992, who were not given intravenous immunoglobulins in the Sultanate of Oman. Our data were compared with a few studies prior to 1992 from the medical literature. Our study revealed a definite benefit with intravenous immunoglobulins. The disease course and hospital stay were shortened. Fewer patients needed ventilation. There was no mortality, and the residual deficit was less than 5%. Occasional relapses at a later stage in the course of illness have been noted in acute Guillain-Barré syndrome. However, acute relapse, a new phenomenon that was not seen in the pre-intravenous immunoglobulin era, stood at 11.9%. Intravenous immunoglobulins have made a significant difference in the outcome of Guillain-Barré syndrome, but one has to be aware of acute relapses, which usually occur in the first 2 to 3 weeks after administration.

Abstract
A young female with no identifiable risk factors developed rapid, overwhelming Staphylococcus aureus endocarditis. Despite rapid sterilization of the blood and the mitral valve with optimal antimicrobials, she had persistent septic shock. In order to investigate this, the toxin-producing capacity of the infecting strain and the patient's ability to produce antibodies were determined. The strain produced high levels of both alpha-toxin and staphylococcal enterotoxin A (SEA), whilst the patient responded with modestly high levels of antibodies to alpha-toxin and low-normal levels to SEA. The patient was most probably susceptible to the actions of SEA and developed a toxic-shock-syndrome-like disease that further aggravated her valvular dysfunction. This case illustrates that optimal antimicrobial therapy alone is not sufficient treatment in patients with persistent toxic shock and that there is a need to evaluate immunomodulatory strategies in such patients.

Abstract
Sixty-eight children 2 months to 14 years of age were admitted with status epilepticus to Sultan Qaboos University Hospital from November 1993 to December 2001. Thirty-eight children (55.9%) had refractory status epilepticus and 30 (44.1%) had established status epilepticus. The children with refractory status epilepticus had received intravenous or per rectal diazepam and intravenous phenytoin/phenobarbital (either or both) before continuous infusion of midazolam was given. Fifty-one children received continuous midazolam infusion. In 38 children with refractory status epilepticus, the midazolam infusion was given in addition to the long-acting antiepilepsy drug, whereas 13 (18.8%) children needed only midazolam to control the established status epilepticus. Seventeen (25%) children were controlled with phenytoin sodium alone. Midazolam was given 0.15 mg/kg/minute initially as bolus in 1 minute, followed by 1 to 7 microg/kg/minute as continuous infusion. The status could not be controlled in one child (1.5%) suffering from neurodegenerative disease. Two children needed mechanical ventilation following prolonged apnea after diazepam administration in one and diazepam plus phenobarbital in the other. No metabolic derangements or compromise of vital functions was noted on midazolam infusion. All children made a complete recovery. There was one death related to meningoencephalitis.

Abstract
OBJECTIVE To analyze all cases of childhood neuropathies (under 14 years of age) and report on their profile, pattern, clinical features and management. METHODS Children with acute flaccid paralysis, longstanding weakness of extremities, neuroregression and children receiving anti cancer drugs with symptoms suggestive of neuropathy were evaluated for evidence of peripheral neuropathy. The evaluation of children with acute flaccid paralysis was a prospective study from January 1992 through to December 2000. The rest of the patients were studied retrospectively from the hospital medical records, pediatric neurology outpatient clinic and the neurophysiology laboratory, Sultan Qaboos University Hospital, Al-Khod, Oman RESULTS Eighty-two (39 Male: 43 Female) children were found to have peripheral neuropathy. Acute Guillain-Barre syndrome was the most common with 37 children (45.1%), followed by genetic neuropathies [hereditary motor and sensory neuropathy with 17 (20.7%), hereditary sensory and autonomic neuropathy with 2 (2.4%), hereditary spastic paraplegia associated neuropathy with 9 (11%) and metachromatic leucodystrophy with 9 (11%)]. Chronic inflammatory demyelinating neuropathy was seen in 5 (6.1%) and vincristine induced neuropathy in 3 (3.5%) children. CONCLUSION Acute Guillain-Barre syndrome is the most common neuropathy amongst the acquired neuropathies. The treatable neuropathies constituted 54.7% (45 children) and the preventable genetic neuropathies accounted for the remaining 45.3% (37 children).

Abstract
An 11-year-old girl presented with headache of 3 months' duration. There was bilateral disc edema. The cerebrospinal fluid pressure was 50 cm of water with normal cerebrospinal fluid cytology and biochemistry. She developed severe headache (different and disabling), dizziness, vomiting, and backache on sitting up 6 hours after lumbar puncture, and lying supine relieved all of her symptoms. Intravenous fluids, analgesics, and complete bed rest did not relieve her symptoms over the next 72 hours. She was completely relieved of her symptoms on receiving two tablets of Caffergot containing 200 mg of caffeine and 2 mg of ergotamine 72 hours after lumbar puncture. The symptoms recurred 48 hours later, and a repeat dose of Caffergot was required. Magnetic resonance imaging (MRI) done 96 hours after lumbar puncture revealed the entire dura overlying the brain, including the posterior fossa, showing intense enhancement on contrast injection with leak at the lumbar puncture site. Oral caffeine (coffee, three times a day) was advised over 1 week. The patient remained asymptomatic, and a repeat MRI scan after 10 days showed complete clearing of the cerebrospinal fluid leak with no dural enhancement. The syndrome of cerebrospinal fluid hypovolemia following lumbar puncture is reported in a girl with idiopathic intracranial hypertension.

Abstract
We present a 2-year old boy with accidental ingestion of a tricyclic antidepressant and outline the clinical features, management and prevention. Despite ingesting a high dose of amitriptyline (20mg/kg) and showing serum levels above the toxic range (1380 ng/ml), our patient did not develop any life threatening complications. Gastric lavage followed by instillation of activated charcoal, repeated at 6 hours, along with supportive measures led to complete recovery in 48 hours. As children are often exposed to tricyclic antidepressant poisoning, their carers and physicians need to be well aware of the disorder and its management.

Abstract
BACKGROUND Recent reports have established that eye changes occur in patients treated with vigabatrin. AIM To identify the eye changes associated with vigabatrin, based on a prospective study of children treated for seizures. METHODS Twenty nine children on vigabatrin (mainly as add on therapy) were followed up for 6.5 years. Ophthalmic examination was performed before starting treatment and then six monthly in the outpatient clinic. RESULTS Twenty one children fulfilled the inclusion criteria. Most had epileptic syndromes with infantile spasms-namely West syndrome, Lennox-Gastaut syndrome, and partial seizures. Vigabatrin dose was 25-114 mg/kg/day (mean 55.8); duration of therapy was 6-85 months (mean 35.7). Four children (19%) developed eye changes (retinal pigmentation, hypopigmented retinal spots, vascular sheathing, and optic atrophy). Visual evoked potentials were abnormal in 16 children. Electroretinography and electro-oculography, which could have picked up eye changes in early stages, were not performed, as this facility was not available. CONCLUSIONS Vigabatrin causes eye damage. Most children with epileptic syndromes on vigabatrin cannot complain of their eye problems, hence 3-6 monthly ophthalmic follow up is strongly advised, along with regular electroretinography, electro-oculography, and visual evoked potentials if possible.

Abstract
Rippling muscle disease (RMD) has previously been reported as a skeletal myopathy that was attributed to a defect in the sarcomere. Here we report a new form of RMD that is more severe, characterized by fatal arrhythmic cardiomyopathy and delayed bone age. Mortality has previously not been associated with RMD. With this report we hope to raise awareness that a subset of patients with this clinical entity are predisposed to severe cardiac disease.

Abstract
Forty-four children (20 male: 24 female) with West syndrome (infantile spasms, mental retardation/regression and hypsarrhythmia) diagnosed at Sultan Qaboos University Hospital (Pediatric Neurology Division of the Department of Child Health) are reported, with thirty-four (77.3%) children constituting the symptomatic group. All children were followed up for an initial 1 year at this hospital. Thirty-seven cases (84%) still continue their follow-up with us. The age of onset ranged from 1 to 14 months (mean, 6.0 months). Developmental delay before the onset of infantile spasms was noted in 29 (65.9%) children. Brain computed tomography was abnormal in 29 (65.9%). Sodium valproate and vigabatrin were the most often used drugs, though other antiepileptic drugs were also used. Nine (24.5%) children achieved good seizure control, out of which five have normal development. Only one child could be weaned off antiepileptic drugs completely. There was one death in the whole series, related to aspiration pneumonia.

Abstract
RATIONALE AND OBJECTIVES Soft-copy viewing of digital radiographs allows for image processing to improve visualization of anatomy and lesions, but it can take more time than film-based viewing. Enhanced visualization processing (EVP) was developed to increase the latitude of an image without reducing the vital contrast, potentially reducing the need for the radiologist to manipulate images. This study examined the influence of processing radiographic images with EVP on workflow in a picture archiving and communications system (PACS). MATERIALS AND METHODS Portable computed radiographic chest images were obtained and processed either with EVP or without. A security camera with a videocassette recorder was positioned above the PACS workstation. Four radiologists reviewed the images during their normal work schedule. The current diagnostic image was used to determine if the case contained EVP or non-EVP images. The videotapes of the sessions were reviewed to determine diagnostic viewing times and how zoom and/or window and level manipulation was used. RESULTS Viewing time was significantly longer for the non-EVP than the EVP cases. The difference occurred with all readers. Window and level manipulation was used on 35% of the EVP and 41% of the non-EVP images. Zoom was used on 64% of the EVP and 69% of the non-EVP images. Average time spent using zoom and window and level manipulation was significantly shorter with the EVP than with the non-EVP images. CONCLUSION EVP of chest images displayed on PACS monitors significantly improved workflow as measured by viewing time. EVP decreased use of window and level manipulation and zooming and the amount of time each one was used.

Abstract
Five children (3F:2M), in the age group 1 years to 11 years, with Munchausen syndrome by proxy are reported from the Sultanate of Oman. They were seen over a four years period from 1996-1999. In all these children, the mother came up with history of uncontrolled epilepsy. Carbamazepine was the most common antiepileptic drug used. One of these children remained hospitalized elsewhere for nearly 9 months, as a case of uncontrolled status epilepticus. It took 18 months to 6 years (mean 2.8 years) to establish the diagnosis and the mother was the offender in all. The main lead to diagnosis, was the disparity between history and clinical presentation to hospital. The carbamazepine levels were several times above the upper limit of therapeutic range. Munchausen syndrome by proxy very much exists here, but is possibly less recognized and needs immediate attention to formulate policies to identify and manage these children. It is necessary to create awareness even in the medical community, to recognise this problem. There is an urgent need to develop a child protection council at the national or regional level.

Abstract
No definite criteria exists in Guillian-Barre syndrome in children regarding prolonged ventilation through an endo-tracheal tube without tracheostomy and successful weaning using a T-piece. Here we report two such cases of Guillian-Barre syndrome requiring prolonged intubation for 56 days and ventilation for 30 days and ultimately successfully weaning them using the T-piece. Both the children eventually made a complete recovery, highlighting the point that in children prolonged intubation and ventilation using the portex tube is equally good, if not, better than tracheostomy with its attendant risks.

Abstract
The purpose of this study was to survey radiologists experienced in soft-copy diagnosis using computer workstations about their current reading room environment, their impressions of the efficacy of their reading room design, and their recommendations based on their experience for improvement of the soft-copy reading environment. Surveys were obtained from radiologists at seven sites representing three major picture archiving and communication system (PACS) vendors throughout the world that have had extensive experience with soft-copy interpretation of radiology studies. The radiologists filled out a detailed survey, which was designed to assess their current reading room environment and to provide them with the opportunity to make suggestions about improvement of the PACS reading rooms. The survey data were entered into a database and results were correlated with multiple parameters, including experience with PACS, types of modalities interpreted on the system, and number of years of experience in radiology. The factors judged to be most important in promoting radiologist productivity were room lighting, monitor number, and monitor brightness. Almost all of the radiologists indicated that their lighting source was from overhead rather than indirect or portable light sources. Approximately half indicated they had the capability of dimming the brightness of the overhead lighting. Most radiologists indicated that they were able to adjust room temperature but that they did not have individual temperature controls at their workstations. The radiologists indicated that the most troublesome sources of noise included background noise, other radiologists, and clinicians much more than noise from computer monitors, technologists, or patients. Most radiologists did not have chairs that could recline or arm rests. Most did have wheels and the capability to swivel, both of which were judged important. The majority of chairs also had lumbar support, which was also seen to be important. Radiologists commonly adjusted room lighting and their reading chair, but rarely adjusted room temperature or monitor brightness. The median number of hours spent at the workstation before taken a "break" was 1.5. Common recommendations to improve the room layout included compartmentalization of the reading room and availability of the hospital/radiology information system at each workstation. The survey data suggest several areas of potential improvement based on radiologists' experience. Optimization of soft-copy reading room design is likely to result in decreased fatigue and increased productivity.

Abstract
Strategies for deployment of picture archiving and communications systems (PACS) in new hospitals often involve the establishment of initial PACS operations. Such a strategy is flawed in the sense that the clinical and radiological users must adapt to PACS operations, while being faced with several other new facility learning curves. This increases the complexity and risk of the radiological services. A strategy of implementing PACS operations in the old facility and performing a zero-downtime transition into the new facility offers several advantages to this method. The successful undertaking of such a project will support not only the physical movement of the existing PACS, but the accomplishment of other re-engineering goals associated with the new hospital. This report will describe the strategy used in two successful transitions of PACS into newly constructed hospitals.
