DYKE–DAVIDOFF–MASSON SYNDROME-A Rare Cause of Cerebral Hemiatrophy in a 17-Years-Old Ethiopian Patient: A Case Report

BACKGROUND: Dyke-Davidoff-Masson syndrome (DDMS) is a rare disease with unknown frequency, mainly presented with seizures, facial asymmetry, contralateral hemiparesis and mental retardation. Often, resulting from brain injury due to a multitude of causes, especially in early life, associated with birth asphyxia. Radiological findings include cerebral hemiatrophy/hypoplasia, calvarial thickening, and hyperpneumatization of the frontal sinuses.CASE PRESENTATION: We report the case of a 17-year-old male patient who presented to Neurology Clinic with complaints of left side body weakness, walking difficulty and poorly controlled seizure for the past 6 years. Brain MRI revealed atrophy of the right cerebral hemisphere.CONCLUSION: Dyke-Davidoff-Masson syndrome should be suspected in any patients who present with classical features and brain imaging showing hemiatrophy. Early identification andtreatment is important in such patients, as it can improve patients prognosis and quality of life

Giant Pituitary Adenoma Presenting with Foster-Kennedy Syndrome in a 21-Year Old Ethiopian Patient: A Rarely Reported Phenomenon: A Case Report

BACKGROUND: Disorders of the pituitary gland and the sellar region present a wide spectrum of clinical problems. A variety of lesions in this area tend to present with similar problems; namely, headache, hormonal disorders, and loss of vision. Benign adenomas of the pituitary gland are by far the most common disorders of sellar region. Rarely, patients with pituitary adenoma may present with blindness in one eye and visual field cut (temporal hemianopia) in the contralateral eye. This rare clinical entity is called Foster-Kennedy Syndrome (FKS).CASE PRESENTATION: We present a 21-year-old male patient, presented with progressive visual disturbance of the left eye, associated with global headache. The headache was refractory to over-counter medications. In addition, he had history of sleep disturbance and loss of appetite. Neurological examination was pertinent for left side visual loss with optic atrophy and right eye temporal visual field cut with disc edema. Brain MRI showed 4 cm X 3.5 cm sized lobulated intra and supra sellar mass with heterogeneous contrast enhancement and minimal surrounding edema. Serum prolactin level was 6,705 ng/mL. Otherwise, the other pituitary hormones were in normal range.CONCLUSION: This case highlighted that pituitary adenoma may present with the full picture of Foster Kennedy syndrome. Therefore, we recommend considering pituitary adenoma as a possible differential diagnosis of intracranial lesions presenting as Foster Kennedy syndrome, as early detection and management could potentially salvage patients’ vision and quality of life

Sellar tuberculoma: a rare presentation in a 30-year-old Ethiopian woman: case report

Background: Tuberculosis rarely involves the hypothalamo-pitutary axis. Only 1% of CNS Tuberculoma involves sellar and suprasellar structures. It mainly presents with symptoms of chiasmal compression, hypopituitarism and diabetes insipidus due to destruction of pituitary itself. Definitive diagnosis is made by tissue analysis collected by trans-sphenoidal biopsy.Case presentation: We report a 30-year-old female patient from Addis Ababa, who presented with a global headache, blurring of vision, excessive polyuria, constitutional symptoms of tuberculosis and multiple axillary lymph node enlargement. Biopsy from the axillary lymph node showed caseous granulomatous lesions and brain MRI showed mild thickening of the pituitary stalk and mildly enlarged posterior piturary lobe with hypo-sellar extension and mild communicating hydrocephalus.Conclusion: Considering the available evidence a diagnosis of systemic tuberculosis involving pituitary, lung and lymph node was made and a patient was started on anti-tuberculosis medication together with dexamethasone and carbamazepine. Following treatment initiation patient showed significant clinical improvement. After nine months of anti-tuberculosis treatment all brain MRI findings were resolved and patient become symptom free and discharged from care after one year completion of anti-tuberculosis medication.Keywords: Tuberculoma, Polyuria, Pituitary gland, Diabetes Insipidu

Bilateral subdural hematoma a rare complication of common procedure in 30-year-old female patient: A case report and literature review

Background: Lumbar puncture (LP) is a frequent procedure done for administration of spinal anesthesia or for obtaining cerebrospinal fluid for analysis. The common complications of LP are pain at the local site and post LP headache. Rarely the following complication could occur: infections of central nervous system, brain stem herniation, and subdural hematoma. Post LP hematoma needs to be suspected in those patients whom post LP conservative management failed and headache lasts more than one week.Case presentation: We report a 30-year-old, Ethiopian woman who present with bilateral subdural hematoma following lumbar puncture for spinal anaesthesia. She presented with three weeks history of persistent headache, nausea and vomiting. The symptoms started three days following spinal anaesthesia procedure done for cesarean section.Conclusion: Post-dural puncture headache is the commonest benign complication of lumbar puncture. However, change in character of headache, absence of response to routine measures, development of neurological signs, and persistence of headache beyond one week should prompt physicians to consider rare and fatal complications of post-dural puncture such as subdural hematoma. Moreover, timely diagnosis and management is often associated with good prognosis. French title: Hematome sous dural bilateral secondaire a une ponction lombaire   Introduction: La ponction lombaire (PL) est une procédure fréquente effectuée pour l'administration de l'anesthésie rachidienne ou pour obtenir du liquide céphalo-rachidien pour analyse. Les complications courantes de la PL sont la douleur au site local et la céphalée post PL. Les complications suivantes sont plus rares : infections du système nerveux central, engagement du tronc cérébral et hématome sous-dural. Un hématome post PL doit être suspecté chez les patients dont la prise en charge conservatrice du syndrome post PL a échoué et chez lesquels les maux de tête durent plus d'une semaine. Observation :Nous rapportons le cas d’une femme éthiopienne de 30 ans qui a présenté un hématome sous-dural bilatéral après une ponction lombaire pour une rachianesthésie. Elle avait des antécédents de céphalées persistantes, de nausées et de vomissements pendant trois semaines. Les symptômes ont commencé trois jours après la procédure d'anesthésie rachidienne effectuée pour la césarienne. Conclusion: La céphalée post-PL est la complication bénigne la plus courante de la ponction lombaire. Cependant, la modification du caractère des céphalées, l'absence de réponse aux mesures de routine, le développement de signes neurologiques et la persistance des céphalées au-delà d'une semaine devraient inciter les médecins à envisager des complications rares et mortelles de la PL telles qu'un hématome sous-dural. De plus, un diagnostic et une prise en charge rapides sont souvent associés à un bon pronostic. &nbsp

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Global burden of 369 diseases and injuries in 204 countries and territories, 1990–2019: a systematic analysis for the Global Burden of Disease Study 2019

Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. Findings: Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990–2010 time period, with the greatest annualised rate of decline occurring in the 0–9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10–24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10–24 years were also in the top ten in the 25–49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50–74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. Interpretation: As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and developm nt investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

Migraine-related disability and co-morbid depression among migraineurs in Ethiopia: a cross-sectional study

Abstract Background Migraine headache is a neurologic disorder which mainly affects younger and productive segment of population. Migraine not only causes pain; but also affects quality of life in terms of low productivity and economic loss. The main aim of this study was to examine migraine-related disability, co-morbid depression, and relationship between the two. Methods A cross-sectional study was conducted among migraineurs who visited two neurology referral clinics. The study was conducted between June 1st 2016 to December 30th2016. Migraine disability assessment score [MIDAS] and patient health questionnaire [PHQ-9] were used to assess disability and depression, respectively. Results A total of 70 patients participated in the study. Fifty-three (74.3%) of our study participants were women. Fifty one (72.9%) study participants were between age group 20–40 years. Migraine without aura was the most common subtype (70%); migraine with aura accounted for the other 28.6%. The mean (± SD) headache frequency and intensity was 23.4 ± 14.9 days and 7.4 ± 1.2 respectively. Major depressive disorder was common in this group (41.4%). The mean MIDAS and PHQ-9 scores were 46.7 ± 30 and 9.2 ± 4.4 respectively. More than two-thirds (74.3%) of our participants had severe disability. We found a statistically significant correlation between migraine-related disability and co morbid depression among our participants(r = 0.318, p-value = 0.007). Conclusion The positive correlation observed between migraine-related disability and co-morbid depression warrant routine screening and treatment of disability and depression in migraineurs; In addition, the observed high degree of disability among our participants may indicate sub optimal treatment of these patients

Severe hypokalemia mimicking Guillain-Barré Syndrome in 42-years-old Ethiopian patient: case report

Acute neuromuscular paralysis is one of the common neurological emergencies, of which Guillain Barre Syndrome (GBS) remains the most common cause. This syndrome presents with acute ascending muscle weakness and loss of deep tendon reflexes (DTR), often preceded by distal paresthesia and back pain. However, a severe hypokalemia may have a similar presentation and put the treating physician in dilemma.We report a 42-year-old previously healthy man, who presented with acute areflexic ascending quadriparesis associated with impending respiratory failure. This followed a one day history of frequent diarrhea, vomiting and low grade fever. A provisional diagnosis of GBS was given by the treating physician and the patient was intubated for ventilatory support. A few hours later the serum potassium and magnesium were reported to be very low, so the patient was given parenteral potassium chloride (KCl), later supplemented with magnesium. Following KCl infusion, the patient’s neurologic and respiratory conditions improved dramatically and he was extubated .Despite continued KCL infusion; however, the patient suddenly sustained cardiac arrest and expired, which is attributable to multiple electrolyte disturbance especially low potassium and low magnesium, it’s important to bear in mind that in 5% of the cases GBS is associated with autonomic dysfunction.Even though severe hypokalemia related muscle weakness reported rarely, it is a potentially treatable and correctable cause of neuromuscular weakness. Therefore treating physician should have this in mind whenever faced with such acute areflexic ascending weakness associated with hypokalemia, especially in resource limited setup like Ethiopia, where it’s difficult to have comprehensive emergency work up for such patients to differentiate possible causes of acute generalized weakness.Keywords: Cardiac arrest, Guillain-Barre syndrome, Hypokalemia, Hypomagnesemi
