Neuroleptic Malignant Syndrome Caused by a Combination of Carbamazepine and Amitriptyline
A 32-year-old female, with a history of secondarily-generalized convulsive epilepsy, mental retardation, and a psychiatric illness, developed neuroleptic malignant syndrome while receiving carbamazepine and amitriptyline concurrently. We hypothesize that the addition of amitriptyline to carbamazepine caused a decrease in the serum level of carbamazepine, resulting in NMS. We conclude that combination therapy with carbamazepine and amitriptyline should be avoided in patients who are predisposed to NMS. The purpose of this paper is to warn physicians against combination therapy with carbamazepine and tricyclic antidepressants which may be conducive to neuroleptic malignant syndrome in susceptible patients
Bruxism Associated with Anoxic Encephalopathy: Successful Treatment with Baclofen
Introduction. Bruxism is a movement disorder characterized by grinding and clenching of the teeth. Etiology of bruxism can be divided into three groups: psychosocial factors, peripheral factors, and pathophysiological factors. Methods. The clinical investigation was conducted at King Khaled Hospital in Hail, Saudi Arabia, in 2012. Results. A 16-year-old Saudi female was brought to the hospital in a comatose state and with generalized convulsive seizures secondary to acute anoxic encephalopathy. In the third week of hospitalization, while still in a state of akinetic mutism, she developed incessant bruxism which responded favorably to a GABA receptor agonist (baclofen). Conclusion. Our data support the hypothesis that bruxism emanates from imbalance or dysregulation of the neurotransmitter system. Larger scale studies will be needed to confirm this hypothesis
Nystagmus in Laurence-Moon-Biedl Syndrome
Introduction. Laurence-Moon-Biedl (LMB) syndrome is a rare autosomal-recessive ciliopathy with manifold symptomatology. The cardinal clinical features include retinitis pigmentosa, obesity, intellectual delay, polydactyly/syndactyly, and hypogenitalism. In this paper, the authors report on three siblings with Laurence-Moon-Biedl syndrome associated with a probable pseudocycloid form of congenital nystagmus. Methods. This was a case study conducted at King Khaled Hospital. Results. The authors assert that the nystagmus in Laurence-Moon-Biedl syndrome is essentially similar to idiopathic motor-defect nystagmus and the nystagmus seen in optic nerve hypoplasia, ocular albinism, and bilateral opacities of the ocular media. Conclusion. The data support the previous hypothesis that there is a common brain stem motor abnormality in sensory-defect and motor-defect nystagmus
Acute Demyelinating Encephalomyelitis(ADEM) Presenting With Dystonia
Introduction: Acute disseminated encephalomyelitis (ADEM) is a monophasic autoimmune inflammatory demyelinating disease of the central nervous system that predominantly involves the white matter of the brain and spinal cord(1). It is a rare disease affecting both children and adults (2). In the majority of cases ADEM usually appears after vaccinations or viral/bacterial infections
Methods: This was a case study of two patients with ADEM presenting with dystonia. The study was conducted at King Khalid Hospital in Hail, Saudi Arabia.
Results: MRI studies showed subcortical white matter lesion in the right frontal region in patient 1, and a right thalamic lesion in patient 2.
Conclusion: We conclude that the lesions detected by the MRI were responsible for the limb dystonia. We believe that the lesions seriously disrupted the cortical-striatal pathways in the right cerebral hemisphere, leading to hemi-dystonia
Cholesterol-Lowering Bioactive Foods and Nutraceuticals in Pediatrics: Clinical Evidence of Efficacy and Safety
Long-term exposure to even slightly elevated plasma cholesterol levels significantly increases the risk of developing cardiovascular disease. The latest evidence recommends an improvement in plasma lipid levels, even in children who are not affected by severe hypercholesterolemia. The riskâbenefit profile of pharmacological treatments in pediatric patients with moderate dyslipidemia is uncertain, and several cholesterol-lowering nutraceuticals have been recently tested. In this context, the available randomized clinical trials are small, short-term and mainly tested different types of fibers, plant sterols/stanols, standardized extracts of red yeast rice, polyunsaturated fatty acids, soy derivatives, and some probiotics. In children with dyslipidemia, nutraceuticals can improve lipid profile in the context of an adequate, well-balanced diet combined with regular physical activity. Of course, they should not be considered an alternative to conventional lipid-lowering drugs when necessary
4. Database of dextrocardiac patients in KFSH & RC: Retrospective analysis of 360 patients over the past 20Â years
Clinical research.
Presentation Type: Oral Presentation
Introduction: Dextrocardia is the right-sided positioning of the human heart during embryological development. It may be isolated or associated with visceral dextroposition or malformations. It is usually discovered during infancy because of associated anomalies or incidentally during adulthood. There is limited information on the associated malformations and their clinical outcomes.
Methodology: This is a retrospective study that describes patients with dextrocardia at King KFSH & RC. A total of 250,000 echocardiograms since 1990 were reviewed for demographics, associated anomalies, clinical outcomes, and mortality.
Results: Three hundred and sixty patients were identified with dextrocardia. Males slightly outnumbered females with a ratio of 193 (53%) to 167 (47%). The majority of subjects (71%) were children and teenagers (2â18Â years). Isolated dextrocardia was the most commonly presented type (48%) followed by situs inversus totalis (43%), situs ambiguous (7%), and situs inversus totalis variant with polysplenia or asplenia (2%), respectively. Cyanotic heart defects were present in more than half of the subjects (54%), while acyanotic heart defects accounted for 25%. Non-cardiac anomalies included Scimitar syndrome (8%), polysplenia (7%), and asplenia (4%). Kaplan Meier survival analysis showed highest death rates among patients with cyanotic heart defects in the first 5 years of life (Figure 1). The overall crude mortality rate is 61 per 1000 patients.
Conclusion: The most common associated anomalies with dextrocardia are cyanotic heart defects, which also account for the majority of deaths in dextrocardiac patients. Scimitar syndrome was reported to be the most common non-cardiac associated anomaly in this population of interest
Molecular and Source-Specific Profiling of Hospital <i>Staphylococcus aureus</i> Reveal Dominance of Skin Infection and Age-Specific Selections in Pediatrics and Geriatrics
Staphylococcus aureus is a major human-associated pathogen that causes a wide range of clinical infections. However, the increased human dynamics and the changing epidemiology of the species have made it imperative to understand the population structure of local ecotypes, their transmission dynamics, and the emergence of new strains. Since the previous methicillin-resistant S. aureus (MRSA) pandemic, there has been a steady increase in global healthcare-associated infections involving cutaneous and soft tissue and resulting in high morbidities and mortalities. Limited data and paucity of high-quality evidence exist for many key clinical questions about the pattern of S. aureus infections. Using clinical, molecular, and epidemiological characterizations of isolates, hospital data on age and infection sites, as well as antibiograms, we have investigated profiles of circulating S. aureus types and infection patterns. We showed that age-specific profiling in both intensive care unit (ICU) and non-ICU revealed highest infection rates (94.7%) in senior-patients > 50 years; most of which were MRSA (81.99%). However, specific distributions of geriatric MRSA and MSSA rates were 46.5% and 4.6% in ICU and 35.48% and 8.065% in non-ICU, respectively. Intriguingly, the age groups 0â20 years showed uniquely similar MRSA patterns in ICU and non-ICU patients (13.9% and 9.7%, respectively) and MSSA in ICU (11.6%). The similar frequencies of both lineages in youth at both settings is consistent with their increased socializations and gathering strongly implying carriage and potential evolutionary replacement of MSSA by MRSA. However, in age groups 20â50 years, MRSA was two-fold higher in non-ICU (35%) than ICU (18.6%). Interestingly, a highly significant association was found between infection-site and age-groups (p-value 0.000). Skin infections remained higher in all ages; pediatrics 32.14%, adults 56%, and seniors 25% while respiratory infections were lower in pediatrics (14.3%) and adults (17%) while it was highest in seniors (38%). Blood and âotherâ sites in pediatrics were recorded (28.6%; 25%, respectively), and were slightly lower in adults (18.6%; 8.6%) and seniors (14%; 22.8%), respectively. Furthermore, a significant association existed between infection-site and MRSA (Chi-Square Test, p-value 0.002). Thus, the common cutaneous infections across all age-groups imply that skin is a significant reservoir for endogenous infections; particularly, for geriatrics MRSA. These findings have important clinical implications and in understanding S. aureus profiles and transmission dynamics across different age groups that is necessary for strategic planning in patient management and infection control
Community-Acquired Methicillin-Resistant <i>Staphylococcus aureus</i> in Hospitals: Age-Specificity and Potential ZoonoticâZooanthroponotic Transmission Dynamics
Methicillin-resistant Staphylococcus aureus (MRSA) lineages are a devastating clinical and public health issue. Data on local lineage profiles are limited. We report on the frequency of community-acquired and hospital-acquired cases (CA-MRSA, HA-MRSA). We studied 147 isolates from King Khalid tertiary care hospitals (KKH), each from a case in a patient and including 33 patients at the Maternity and Childrenâs Hospital (MCH). Of the 147 isolates, 87 males (59%) and 60 females (41%) were in KKH. The overwhelming majority (80%; n = 119/147) were CA-MRSA in KKH. Intriguingly, despite significant differences between males (70%) and females (53%), lineage-acquisition remained age-specific around 58â60 years in both genders. However, while CA-MRSA dominated early in life (0â20, 70% MCH), it increased with age in KKH adults; 21â50 (28%), >50 (59%) until the overall 80% (n = 144/180). Major specimens included skin-wounds, surgeries (70.3%), blood (13.5%), sputum (8.8%), very rarely urine (4.1%), and nasal (3.4%), albeit most patients showed severe enteritis and necrotizing pneumonia. Antibiograms showed high beta lactam resistances, including amoxicillinâclavulanate (83%), oxacillin (84%), cefoxitin FOX (100%), penicillin and ampicillin (~100%), as well as high resistance (82%) to carbapenem. Fortunately, high susceptibility was seen to non-beta lactams and, to a lesser extent, gentamicin, erythromycin, and fusidic acid; 33%, 34%, and 38%, respectively, in KKH. A similar pattern was seen in MCH except for a low resistance pattern to gentamicin CN, clindamycin CD, erythromycin E, and tobramycin TOB; 34%, 31%, 39%, and 41%, respectively, except for fusidic acid. These findings have significant clinical implications for MRSA patient management strategies. Clinical- and lineage-profiles imply host-selection and zoonoticâzooanthroponotic transmission dynamics. Future molecular typing, sequencing, and characterization of dominant clone(s) is imperative
