ABSTRACT

BACKGROUND AND OBJECTIVE: Parathyroid hormone (PTH) resistance, the main biochemical feature of a rare group of disorders known as Pseudohypoparathyroidism (PHP) is an uncommon cause of hypocalcaemia. In addition to the biochemical abnormalities, some individuals with PHP may have features of Albright Hereditary Osteodystrophy (AHO). Being a rare disorder with a significant level of variation and overlap in its clinical presentation, diagnosis of PHP may be challenging in some clinical settings. This case report highlights the diagnosis of this rare disorder. CASE REPORT: A 20-year-old Ghanaian female who had been involved in a road traffic accident (RTA) was referred to the endocrine clinic after a computer tomography (CT) scan of her head revealed an incidental finding of multiple basal ganglia calcifications. Investigations revealed hypocalcaemia, hyperphosphatemia, and elevated intact PTH in the presence of normal levels of 25-hydroxyvitamin D and magnesium, and a normal kidney function. She also had phenotypic features of AHO. Findings suggested a diagnosis of PHP, however, the type could not be identified due to the unavailability of further testing. CONCLUSION: This report of a Ghanaian female with PTH resistance and features of AHO diagnosed at the age of 20 years, is expected to add to the existing literature and assist in increasing the level of awareness and facilitate the diagnosis of this disorder in our setting.


CONTEXTE ET OBJECTIF: La résistance à l'hormone parathyroïdienne (PTH), principale caractéristique biochimique d'un groupe rare de troubles connus sous le nom de pseudohypoparathyroïdie (PHP), est une cause rare d'hypocalcémie. En plus des anomalies biochimiques, certaines personnes atteintes de PHP peuvent présenter des caractéristiques d'ostéodystrophie héréditaire d'Albright (AHO). Étant un trouble rare avec un niveau significatif de variation et de chevauchement dans sa présentation clinique, le diagnostic de PHP peut être difficile dans certains contextes cliniques. Ce rapport de cas met en lumière le diagnostic de cette maladie rare. RAPPORT DE CAS: Une femme ghanéenne de 20 ans qui avait été impliquée dans un accident de la circulation routière (RTA) a été référée à la clinique endocrinienne après qu'une tomodensitométrie (TDM) de sa tête a révélé la découverte fortuite de multiples calcifications des ganglions de la base. Les examens ont révélé une hypocalcémie, une hyperphosphatémie et une PTH intacte élevée en présence de taux normaux de 25 hydroxyvitamine D et de magnésium et d'une fonction rénale normale. Elle avait également des caractéristiques phénotypiques d'AHO. La découverte a suggéré un diagnostic de PHP, mais le type n'a pas pu être identifié en raison de l'indisponibilité de tests supplémentaires. CONCLUSION: Ce rapport d'une femme ghanéenne présentant une résistance à la PTH et des caractéristiques d'AHO diagnostiquée à l'âge de 20 ans, devrait s'ajouter à la littérature existante et aider à accroître le niveau de sensibilisation et à faciliter le diagnostic de ce trouble dans notre contexte.

ABSTRACT

BACKGROUND: Anecdotally, increasing number of patients are seen at Korle Bu Teaching Hospital (KBTH) with brain tumour. Neuro-ophthalmic symptoms and signs may help in timely diagnosis and intervention. OBJECTIVE: To evaluate the neuro-ophthalmic and clinical characteristics of brain tumour in patients presenting at a tertiary hospital in Ghana. STUDY DESIGN: A prospective case series involving 36 consecutive patients newly diagnosed with brain tumour from November 2010 to October 2011, at the Ophthalmology, Neurosurgery and Endocrine units of KBTH, Ghana. All patients had clinical diagnosis of brain tumour with confirmation by computerized tomography (CT) or magnetic resonance imaging (MRI). Thirteen patients had histological confirmation of diagnosis. OUTCOME MEASURES: Presenting Visual acuity, Colour vision, Visual fields and Cranial nerve deficits. RESULTS: Data of 36 patients were analyzed. Ages ranged from 3 to 69 years, mean (SD) 42.56 (±16.6 years). Twenty-six (72%) were females. Tumours included pituitary adenoma (20, 55.5%), meningioma(10, 27.8%), choroid plexus tumour(1, 2.8%), medulloblastoma(1, 2.8%), craniopharyngioma(1, 2.8%), haemangioblastoma(1, 2.8%), thalamic tumour(1, 2.8%) and haemangioma(1, 2.8%). Histologically confirmed tumours included pituitary adenoma (9, 69.2%), meningioma (3, 23.1%), craniopharyngioma (1, 7.7%). One patient had both a pituitary adenoma and meningioma. Blurred vision (30, 83.3%), headache (28, 77.8%) and photophobia (13, 36.1%) were predominant symptoms. Commonest neuro-ophthalmic signs were impaired colour vision (62 eyes, 88.6%), optic atrophy (26, 74.3%), unilateral or bitemporal hemianopia (15, 41.5%) and relative afferent pupillary defect (12, 34.3%). Seven (19.4%) patients were visually impaired and nine (25%) blind. Thirty-three of 72 (45.8%) eyes had monocular blindness. CONCLUSIONS: Common neuro-ophthalmic characteristics were blurred vision, headache, impaired colour vision, optic atrophy, and relative afferent pupillary defect (RAPD). Significant numbers of patients were blind or visually impaired at presentation.

ABSTRACT

BACKGROUND: Persistent hyperglycaemia is a hallmark of Diabetes Mellitus (DM). It causes increased production of free radicals, especially reactive oxygen species (ROS), - resulting in oxidative stress. Reactive Oxygen Species have been implicated in the development of haematological complications in patients with diabetes. Superoxide Dismutase (SOD) is one of the most effective antioxidant enzyme defense systems against free radicals. METHODS: From February through May 2014, we assessed the relationship between oxidative stress and haematological profiles among individuals with and without diabetes. A cross sectional study of 66 case patients and 44 age-matched controls were recruited from the National Diabetes Management and Research Centre (NDMRC), Korle-Bu Teaching Hospital, Accra, Ghana. Blood samples were obtained from study participants with consent. We determined the haematological profiles of study participants and measured their oxidative stress levels using a standardized kit for SOD activity. RESULTS: Higher white blood cell (WBC) counts were seen in the diabetes cohort (p-value = 0.023). The SOD activity tended to be lower in diabetes patients (p-value = 0.144 however) while higher neutrophil levels seemed to correlate with SOD activity (R = 0.249; R2 = 6.2 %; p-value = 0.049). There did not appear to be a correlation between fasting blood glucose (FBG) and SOD activity (R = -0.044; p-value = 0.727). CONCLUSION: The study reports similar oxidative stress levels, as measured by SOD activity, in diabetic and non-diabetic adults. The SOD activity did not appear to correlate with FBG and several other haematological parameters. Further study would be required to investigate the relationship between these haematological indices and diabetic micro- and macro-vascular complications in our population.

ABSTRACT

BACKGROUND: There is evidence linking the Metabolic Syndrome with an increased risk of developing cardiovascular disease, previously thought to be rare in Africa but now a major public health concern. OBJECTIVES: To determine the frequency of occurrence of the Metabolic Syndrome among patients presenting with cardiovascular disease at the Korle Bu Teaching Hospital, Ghana. METHODS: This was a case-control study of 100 consecutive cardiovascular disease patients and 100 age- and sex- matched controls who underwent an interview and physical examination. Anthropometric measurements and fasting blood samples for plasma glucose and lipids were taken. The National Cholesterol Education Programme: Adult Treatment Panel III criteria were used for the diagnosis of the Metabolic Syndrome. RESULTS: The prevalence of Metabolic Syndrome among cases and controls was 54% and 18% respectively, with the prevalence increasing with advancing age. Hypertension and central obesity were the two components with the highest frequency among individuals with Metabolic Syndrome. The Metabolic Syndrome was associated with the development of cardiovascular disease (OR=5.35, 95% CI: 2.81-10.18, p=0.0001), with the odds ratio increasing with the number of components present. CONCLUSION: The Metabolic Syndrome is prevalent among cardiovascular disease patients attending the Korle Bu Teaching Hospital, with a significant association between the number of components of the Metabolic Syndrome present and the probability of developing a cardiovascular disease. A policy to institute routine screening in clinical practice and provision of appropriate interventions for Metabolic Syndrome components among Ghanaian adults is needed.
