Idiopathic Mental Retardation

Abstract Background: Mental retardation is a group of heterogeneous disorders associated with generalized developmental delay during infancy and early childhood, while impairment in cognitive functions and adaptive behaviors became generally apparent during pre-school and early school years depending on the severity of the condition. Little is known about the etiology of mental retardation in Iraq. The aim of this paper is to describe the etiology of mental retardation in a sample of Iraqi children. Patients and methods: During one-year period (February 2018 to February 2019), thirty-six patients with mental retardation (25 males and 11 females) were observed at the neuropsychiatry clinic at the Children Teaching hospital of Baghdad Medical City. Their ages ranged from two to seventeen years. Patients with cerebral palsy, atypical autism with mental retardation and Rett syndrome were not included in this series. Results: Eighteen patients (50%) had idiopathic mental retardation (11 males and 7 females). Seven patients (19%) had Down syndrome (5 males and 2 females). Two male patients had Beckwith Wiedemann syndrome, one of them had an affected brother. Three males had inborn errors of metabolism, each one had phenylketonuria, homocystinuria and Lesch Nyhan syndrome. The patient with Lesch Nyhan syndrome had an older brother who died from the same condition. Six patients each one had Prader-Labhart-Willi syndrome, Sanjad Sakati Richardson Kirk syndrome, Coffin Siris syndrome, kernicterus, Bartter syndrome, Pediatric Huntington disease. Nonspecific abnormalities were present in three patients and included bilateral optic atrophy in one boy, squint and obesity in one girl and a second girl had large ears. Brain CT-scan was available for two patients with idiopathic mental retardation and one patient with kernicterus and showed normal findings. Conclusion: The causes of mental retardation in about two thirds of Iraqi patients with mental retardation were idiopathic mental retardation and Down syndrome.

Idiopathic Mental Retardation

Background: Down syndrome is an extensively studied chromosomal disorder characterized by mental retardation and distinct physical manifestations, and it is the second most common cause of mental retardation in Iraqi children after idiopathic mental retardation. However, the chronic cutaneous conditions associated with the syndrome have received relatively inadequate attention. This paper aims to determine chronic cutaneous disorders persisting more than six months or reoccurring over six months in Down syndrome patients. Patients and Methods: Twenty-seven patients (17 males and 10 females) with Down syndrome were observed at the Children Teaching Hospital of Baghdad medical City and the Medical Consultation Clinic of Iraq headquarter of Copernicus Scientists international panel in Baghdad during 2018 and 2019. Their ages when they were first seen ranged from 4 months to 30 years. Results: Chronic cutaneous disorders were observed in four patients of the twenty-seven patients observed. Three patients including a thirteen-year-old girl and two boys had alopecia areata, and a man aged thirty years had familial baldness and Tinea corporis of the dorsum of the right hand. Conclusions: This paper highlights the association between Down syndrome and Tinea corporis which has not been noticeably emphasized in the medical literature.

Abstract Introduction/Objective The aim of this study was to investigate the effects of GH administration on basic coagulation parameters: PT, aPTT and fibrinogen concentrations in adult GHD patients before and during one year of GH replacement. Methods Twenty-one adult patients with severe GHD (mean age +/- SE: 38.6 +/- 2.8 years) were included in this hospital based, prospective, interventional study. All patients were treated with rhGH for 12 months (GH dose: 0.4 mg/day for male and 0.6 mg/day for female patients). IGF-1 concentrations were determined using RIA-INEP kits. Basic coagulation tests, i.e. aPTT and fibrinogen concentrations, were measured before and after 3, 6 and 12 months of treatment with rhGH. Control values were obtained from fourteen “healthy” subjects matched by age, sex and body mass index (BMI). Results At baseline, we observed no significant differences in PT, aPTT and fibrinogen values between GHD and healthy subjects. IGF-1 concentrations increased significantly within 3 months of GH therapy (8.2 +/- 1.5 vs. 24.2 +/- 2.9 nmol/l, p <0.05) and remained stable thereafter. A significant increase in PT values, which was more pronounced in female subjects, was noted after 6 and 12 months of treatment with GH. aPTT values increased significantly after 12 months of treatment only in male patients (28.8 +/- 4.6 vs. 39.7 +/- 2.1 s.; p <0.05). No significant changes in fibrinogen concentrations were found during the study. Conclusion Twelve months of GH replacement therapy led to a significant increase in PT and aPTT values in adult GHD patients, while fibrinogen concentrations did not change. Changes in PT were more pronounced in female GHD patients, while an increase in aPTT values was observed only in male patients with GHD. The clinical significance of these changes needs further evaluation.

Logit, probit and complementary log-log models are the most widely used models when binary dependent variables are available. Conventionally, these models have been frequentists. This paper aims to demonstrate how such models can be implemented relatively quickly and easily from a Bayesian framework using Gibbs sampling Markov chain Monte Carlo simulation methods in WinBUGS. We focus on the modeling and prediction of Down syndrome (DS) and Mental retardation (MR) data from an observational study at Kuwait Medical Genetic Center over a 30-year time period between 1979 and 2009. Modeling algorithms were used in two distinct ways; firstly, using three different methods at the disease level, including logistic, probit and cloglog models, and, secondly, using bivariate logistic regression to study the association between the two diseases in question. The models are compared in terms of their predictive ability via R2, adjusted R2, root mean square error (RMSE) and Bayesian Deviance Information Criterion (DIC). In the univariate analysis, the logistic model performed best, with R2 (0.1145), adjusted R2 (0.114), RMSE (0.3074) and DIC (7435.98) for DS, and R2 (0.0626), adjusted R2 (0.0621), RMSE (0.4676) and DIC (23120) for MR. In the bivariate case, results revealed that 7 and 8 out of the 10 selected covariates were significantly associated with DS and MR respectively, whilst none were associated with the interaction between the two outcomes. Bayesian methods are more flexible in handling complex non-standard models as well as they allow model fit and complexity to be assessed straightforwardly for non-nested hierarchical models.

Abstract The purpose of this study was to identify the risk factors associated with low peripheral oxygen saturation (SpO2) and delayed recovery of dental patients with disabilities after intravenous sedation. A total of 1213 patients with disabilities were retrospectively investigated with respect to demographic parameters and sedation conditions. Multivariate logistic analyses were conducted for patients with an SpO2 <90% and a recovery period of >60 minutes to identify the risk factors for poor sedation conditions. A significant odds ratio related to decreased SpO2 was observed for age, sex, midazolam and propofol levels, concurrent use of nitrous oxide, cerebral palsy, Down syndrome, and mental retardation. The most problematic patients were those diagnosed with Down syndrome (odds ratio, 3.003–7.978; 95% confidence interval; P < .001). Decision tree analysis showed an increased risk of decreased SpO2 in males with Down syndrome or after administration of >0.493 mg/kg propofol in combination with midazolam. An increased risk of delayed awakening was seen in patients aged less than 21 years and in males administered >0.032 mg/kg of midazolam. Intravenous sedation for dental patients with disabilities, particularly those with cerebral palsy, Down syndrome, or mental retardation, increases the risk of decreased SpO2. In addition, delayed recovery is expected after midazolam administration.
