Neonatal parotitis

Neonatal parotitis is a rare condition. Infection of the parotid glad is more common than that of the submandibular glad. Dehydration is the most important predisposing factor for this. Most common organism responsible for this condition is Staphylococcus aureus. Untreated condition can lead to various complications.     

A comprehensive view of sex-specific issues related to cardiovascular disease

Cardiovascular disease (CVD) is the leading cause of mortality in women. In fact, CVD is responsible for a third of all deaths of women worldwide and half of all deaths of women over 50 years of age in developing countries. The prevalence of CVD risk factor precursors is increasing in children. Retrospective analyses suggest that there are some clinically relevant differences between women and men in terms of prevalence, presentation, management and outcomes of the disease, but little is known about why CVD affects women and men differently. For instance, women with diabetes have a significantly higher CVD mortality rate than men with diabetes. Similarly, women with atrial fibrillation are at greater risk of stroke than men with atrial fibrillation. Historically, women have been underrepresented in clinical trials. The lack of good trial evidence concerning sex-specific outcomes has led to assumptions about CVD treatment in women, which in turn may have resulted in inadequate diagnoses and suboptimal management, greatly affecting outcomes. This knowledge gap may also explain why cardiovascular health in women is not improving as fast as that of men. Over the last decades, mortality rates in men have steadily declined, while those in women remained stable. It is also becoming increasingly evident that gender differences in cultural, behavioural, psychosocial and socioeconomic status are responsible, to various degrees, for the observed differences between women and men. However, the interaction between sex-and gender-related factors and CVD outcomes in women remains largely unknown.     

Experience with Kangaroo mother care in a neonatal intensive care unit (NICU) in Chandigarh, India

Objective  To study the feasibility and acceptability of Kangaroo mother care (KMC) on the low birth weight infants (LBWI) in the neonatal intensive care unit (NICU) by the mothers, family members and health care workers (HCW) and to observe its effect on the vital parameters of the babies. Method  A observation in the NICU. Results  A total of 135 babies (74 boys and 61 girls) who completed minimum of 4 hrs of KMC/day, were included. The mean birth weight and gestation were 1460gm and 30 week respectively. 47% babies started KMC within first week of age. Mean duration of KMC was 7 days (3–48) days. The O₂ saturation improved by 2–3%, temperature (°C) rose from 36.75 ± 0.19 to 37.23 ± 0.25, respiration stabilized (p<0.05 for all) and heart rate dropped by 3–5 beats. No episodes of hypothermia or apnea were observed during KMC. KMC was accepted by 96 % mothers, 82% fathers and 84% other family members. 94% HCW considered it to be safe and conservative method of care of LBWI. Benefits of KMC on the babies’ behavior and on maternal confidence and lactation were reported by 57%, 94% and 80% respectively. A decline in use of heating devices in the NICU was reported by 85% and 79% said it did not increase their work load. Conclusion  KMC was found to be safe, effective and feasible method of care of LBWI even in the NICU settings. Positive attitudes were observed in mothers, families and HCW.     

ACTH therapy in refractory generalized epilepsy

Adrenocorticotropic hormone (ACTH) has a long track record for the treatment of infantile spasms. However, there is paucity of data on the use of ACTH in the treatment of epilepsy beyond infantile spasms. We report the use of ACTH in two children with refractory generalized epilepsy. Both patients responded well. ACTH may be considered as a useful adjunctive therapy in patients with intractable generalized seizures. Side effects and cost however, remain important concerns.     

Role of HLA class II genes in susceptibility/resistance to inflammatory arthritis: studies with humanized mice

Summary: Predisposition to develop rheumatoid arthritis (RA) has been associated with certain human leukocyte antigen (HLA) class II molecules, although the mechanism is still unknown. Various experimental animal models of inflammatory arthritis have been studied to address the role of major histocompatibility complex (MHC) genes in pathogenesis. We have generated transgenic mice expressing HLA class II molecules (DR and DQ) lacking complete endogenous class II molecules to study the interactions involved between class II molecules (DQ and DR) and to define the immunologic mechanisms in inflammatory arthritis. The HLA transgene can positively select CD4⁺ T cells expressing various Vβ T-cell receptors, and a peripheral tolerance is maintained to transgenic HLA molecules. The expression of HLA molecules on various cells in these mice is similar to that known in humans. In this review, we describe collagen-induced arthritis as a model for human inflammatory arthritis using these transgenic mice. The transgenic mice carrying RA-susceptible haplotype develop gender-biased inflammatory arthritis with clinical and histopathological similarities to RA. Our studies show that polymorphism of HLA class II genes determine the predisposition to rheumatoid/inflammatory arthritis and the epistatic interactions between HLA-DQ and HLA-DR molecules dictate the severity, progression, and modulation of the disease.     

Cognitive effects of nicotine in humans: an fMRI study

To elucidate the neural correlates of cognitive effects of nicotine, we examined behavioral performance and blood oxygenation level-dependent regional brain activity, using functional magnetic resonance imaging, during a parametric "n-back" task in healthy nonsmoking males after the administration of nicotine (12 microg/kg body weight) or saline. Nicotine, compared to placebo, improved accuracy (P = 0.008) in all active conditions (2%-11%), and had a load-specific effect on latency (P = 0.004; 43.78% decrease at the highest memory load). Within a network of parietal and frontal areas activated by the task (P < 0.05, corrected at the voxel level), nicotine produced an increased response (P < 0.05; uncorrected within the regions of interest) in the anterior cingulate, superior frontal cortex, and superior parietal cortex. It also produced an increased response in the midbrain tectum in all active conditions and in the parahippocampal gyrus, cerebellum, and medial occipital lobe during rest (P = 0.05; uncorrected). The present observations point to altered neuronal activity in a distributed neural network associated with on-line task monitoring and attention and arousal systems as underlying nicotine-related enhancement of attention and working memory in human subjects.     

Capitalizing on technology for developing communication skills in autism spectrum disorder: a single case study

Purpose: In this case study, we discuss the application of a patient-centred clinical approach that led to the use of an assisted communication platform to combat severe communicative deficit in a child with autism spectrum disorder (ASD).

Methods: Initial assessment at four years of age revealed that the patient had rudimentary communication skills, with significant sensory integration dysfunction manifested as oral, olfactory, and tactile seeking behaviours; self-stimulatory behaviour; and complete dependence on caregiver for activities of daily living. Intensive, multi-disciplinary intervention resulted in minimal improvement in communicative skills and sensory seeking over six months. Subsequently, a tailor-made picture-assisted communication training with the mother as the communication facilitator was adopted. This approach was abandoned due to the patient’s poor response and mother’s low acceptance of picture-based interaction. A preference for printed material was observed in the patient. Accordingly, further management was focused on employing a computer-based interactive platform that the patient was taught to use over the course of a few months as a part of augmentative and alternative communication (AAC) intervention program. This resulted in a remarkable improvement in the child’s skills that now allowed for a better intentional communication of his thoughts and needs.

Conclusions: This study highlights the importance of revisiting conventional rehabilitation strategies for communicative deficits and tailoring them according to the patient’s needs and preferences. It also emphasises that besides excellent observation skills, clinicians must be willing to consider technology based approaches in patients responding poorly to traditional approaches in order to develop effective interventional programmes.

• Implication for Rehabilitation

• The current study highlights the importance of exploring the application of technology based intervention for building communication skills in the early stages of rehabilitation for persons with communicative deficit.

• It also emphasises the need for excellent observation skills among clinicians so that the peculiar interests of children with ASD may be applied in designing training programmes to overcome communication barriers.

• Additionally, clinicians should familiarise themselves with the latest assistive technology-based rehabilitation approaches and be willing to explore newer approaches if traditional ones fail to yield satisfactory outcomes.

• Use of technology-based interventions to reduce dependence among persons with disability would be beneficial, both socially and economically, in developing countries with limited resources.

     

Anthropometry, glucose tolerance, and insulin concentrations in Indian children: relationships to maternal glucose and insulin concentrations during pregnancy

OBJECTIVE: The purpose of this study was to test the hypothesis that the environment experienced by fetuses of mothers with gestational diabetes mellitus (GDM) and mothers with higher glucose concentrations that are in the normal range causes increased adiposity and altered glucose/insulin metabolism in childhood. RESEARCH DESIGN AND METHODS: Children (n = 630) whose mothers were tested for glucose tolerance during pregnancy had detailed anthropometry performed at birth and annually thereafter. At 5 years, plasma glucose and insulin concentrations were measured in the children (2-h oral glucose tolerance test) and their fathers (fasting samples only). RESULTS: Newborns of diabetic mothers (n = 41) were larger in all body measurements than control newborns (babies with nondiabetic parents). At 1 year, these differences had diminished and were not statistically significant. At 5 years, female offspring of diabetic mothers had larger subscapular and triceps skinfold thicknesses (P = 0.01) and higher 30- and 120-min insulin concentrations (P < 0.05) than control children. Offspring of diabetic fathers (n = 41) were lighter at birth than control children (P < 0.001); they showed no differences in anthropometry at 5 years. In control children, skinfold thickness and 30-min insulin concentrations were positively related to maternal insulin area under the curve, and skinfold thicknesses were related to paternal fasting insulin concentrations independently of the parents' skinfold thickness and socioeconomic status. CONCLUSIONS: Maternal GDM is associated with adiposity and higher glucose and insulin concentrations in female offspring at 5 years. The absence of similar associations in offspring of diabetic fathers suggests a programming effect in the diabetic intrauterine environment. More research is needed to determine whether higher maternal glucose concentrations in the nondiabetic range have similar effects.
