"Those who care much, understand much." Maternal perceptions of children's appetite: Perspectives from urban and rural caregivers of diverse parenting experience in Bangladesh

Appetite in children is an important determinant of nutritional intake and growth. The information used by caregivers to understand children's appetite can help inform infant and young child feeding promotion and appetite assessment. We conducted a qualitative study to (a) explore maternal perceptions and responses to children's appetite and (b) to identify how these factors differ by type of caregiver, level of maternal experience, and urban versus rural context. We used purposive sampling to recruit mothers and alternate caregivers into 14 total focus group discussions (six to eight participants in each group; N = 95) in both urban and rural settings in Bangladesh. To understand children's appetite, caregivers monitor children's dietary patterns, emotional signs, and physical and verbal cues. Healthy appetite was observed by willingness to eat diverse foods, finish offered portions, and by acceptance of foods without excessive prompting. Child illness was cited for a cause of low appetite, which was manifested through fussiness, and avoiding commonly consumed foods. Mothers described a limited set of feeding practices (offering diverse foods, playing, and cheering children with videos) to encourage consumption when children lacked appetite. Mothers' stress related to work was noted as a barrier to identifying appetite cues. Urban mothers described a lower access to instrumental social support for child feeding but informational support than mothers in the rural setting. Understanding caregivers' perceptions of children's appetite may inform strategies to improve responsive feeding and tool development to assess changes in appetite as early indicators of change in health or nutrition status among high-risk children.

Efficacy of World Health Organization guideline in facility-based reduction of mortality in severely malnourished children from low and middle income countries: A systematic review and meta-analysis

AIM

Globally more than 19 million under-five children suffer from severe acute malnutrition (SAM). Data on efficacy of World Health Organization's (WHO's) guideline in reducing SAM mortality are limited. We aimed to assess the efficacy of WHO's facility-based guideline for the reduction of under-five SAM children mortality from low and middle income countries (LMICs).

METHODS

A systematic search of literature published in 1980-2015 was conducted using electronic databases. Additional articles were identified from the reference lists and grey literature. Studies from LMICs where SAM children (0-59 months) were managed in facilities according to WHO's guideline were included. Outcome was reduction in SAM mortality measured by case fatality rate (CFR). The review was reported following the Grading of Recommendations Assessment Development and Evaluation and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline and meta-analyses done using RevMan 5.3®.

RESULTS

This review identified nine studies, which demonstrated reductions in SAM mortality. CFR ranged from 8 to 16% where WHO guideline applied. High rates of poverty, malnutrition, severe co-morbid condition, lack of resources and differences in treatment practices played a key role in large CFR variation. Most death occurred within 48 h of admission in Asia, between 4 days and 4 weeks in Africa and in Latin America. CFR was reduced by 41% (odds ratio: 0.59; 95% confidence interval: 0.46-0.76) when WHO guideline were applied. A 45% reduction in CFR was achieved after excluding human immunodeficiency virus positive cases. Dietary management also differed among WHO and conventional management.

CONCLUSION

Children receiving SAM inpatient care as per WHO guideline have reduced CFR compared to conventional treatment.

Induced membrane technique for treating tibial defects gives mixed results

Aims

This study describes the use of the Masquelet technique to treat segmental tibial bone loss in 12 patients.

Patients and Methods

This retrospective case series reviewed 12 patients treated between 2010 and 2015 to determine their clinical outcome. Patients were mostly male with a mean age of 36 years (16 to 62). The outcomes recorded included union, infection and amputation. The mean follow-up was 675 days (403 to 952).

Results

The mean tibial defect measured 5.8 cm (2 to 15) in length. Of the 12 patients, 11 had an open fracture. Eight underwent fixation with an intramedullary nail, three with plates and one with a Taylor Spatial Frame. The mean interval between stages was 57 days (35 to 89). Bony union was achieved in only five patients. Five patients experienced infective complications during treatment, with two requiring amputation because of severe infection.

Conclusion

The Masquelet technique was relatively ineffective in achieving union in this series, and was associated with a high rate of infection. Cite this article: Bone Joint J 2017;99-B:680–5.

Bites by the Monocled Cobra, Naja kaouthia, in Chittagong Division, Bangladesh: Epidemiology, Clinical Features of Envenoming and Management of 70 Identified Cases

AbstractWe describe 70 cases of monocled cobra (Naja kaouthia) bite admitted to Chittagong Medical College Hospital, Bangladesh. The biting snakes were identified by examining the dead snake and/or detecting N. kaouthia venom antigens in patients' serum. Bites were most common in the early morning and evening during the monsoon (May-July). Ligatures were routinely applied to the bitten limb before admission. Thirty-seven patients consulted traditional healers, most of whom made incisions around the bite site. Fifty-eight patients experienced severe neurotoxicity and most suffered swelling and pain of the bitten limb. The use of an Indian polyvalent antivenom in patients exhibiting severe neurotoxicity resulted in clinical improvement but most patients experienced moderate-to-severe adverse reactions. Antivenom did not influence local blistering and necrosis appearing in 19 patients; 12 required debridement. Edrophonium significantly improved the ability of patients to open the eyes, endurance of upward gaze, and peak expiratory flow rate suggesting that a longer-acting anticholinesterase drug (neostigmine) could be recommended for first aid. The study suggested that regionally appropriate antivenom should be raised against the venoms of the major envenoming species of Bangladesh and highlighted the need to improve the training of staff of local medical centers and to invest in the basic health infrastructure in rural communities.

Predicting the pain continuum after adolescent idiopathic scoliosis surgery: A prospective cohort study

BACKGROUND

Chronic postsurgical pain (CPSP) affects half a million children annually in the United States, with dire socioeconomic consequences, including long-term disability into adulthood. The few studies of CPSP in children are limited by sample size, follow-up duration, non-homogeneity of surgical procedure and factors evaluated.

METHODS

In a prospective study of 144 adolescents undergoing a single major surgery (spine fusion), we evaluated demographic, perioperative, surgical and psychosocial factors as predictors of a continuum of postsurgical pain: immediate, pain maintenance at 2-3 months (chronic pain/CP) and persistence of pain a year (persistent pain/PP) after surgery.

RESULTS

We found an incidence of 37.8% and 41.8% for CP and PP. CP and acute pain were both significant predictors for developing PP (p-value <0.001 and 0.003). Preoperative pain and higher postoperative opioid requirement was significantly associated with CP (p = 0.015, p = 0.002), while Childhood Anxiety Sensitivity Index (p = 0.002) and surgical duration (p = 0.014) predicted PP. The final regression models had reasonable predictive accuracy (c-statistic of 0.73 and 0.83 for CP and PP, respectively). Anxiety scores and catastrophizing for child and parent were found to be significantly correlated (p = 0.005, p = 0.013 respectively). Pain trajectories revealed that 65% of patients who developed PP reported CP and high pain trends; however, 33% of those who developed PP could not be identified using solely pain criteria.

CONCLUSION

Persistent postsurgical pain in children is a significant problem. It can be predicted in part by combinations of psychological and clinical variables, which may provide evidence-based measures to prevent development of CPSP in the future.

SIGNIFICANCE

In a homogeneous cohort of adolescents undergoing spine fusion, we report a high incidence of persistent postsurgical pain (41.8%) predicted by child anxiety, perioperative pain, and surgical duration. Our results stress timely preventive and therapeutic strategies.

Echocardiographic comparison of regional wall motion abnormality between patients with acute anteroseptal and acute extensive anteior ST segment elevation myocardial infarction

Post myocardial infarction (MI) short and long-term clinical outcome is largely determined by the size of the infarcted area. It is generally assumed that as the lead involvement in electrocardiography (ECG) is less in anteroseptal ST segment elevation myocardial infarction (AS-STEMI), where ST segment elevation (STE) is limited to leads V1 to V3, myocardial damage is likely to be less; and in extensive anterior STEMI (EA-STEMI), as the STE extends further upto V6, the myocardial damage is likely to be more. This study was intended to compare regional wall motion abnormality (RWMA) between acute anteroseptal STEMI and acute extensive anterior STEMI patients. 90 patients with AS-STEMI and 106 patients with EA-STEMI, admitted in between October 2012 and September 2013, were included. For each patient, a transthoracic echocardiogram (TTE) was performed within 24-48 hours of MI and was interpreted by an independent investigator blinded to the patient's ECG data. No differences were observed between the two groups in baseline characteristics; except AS-STEMI group had more patients with diabetes and EA-STEMI group had more patients with family history of coronary artery disease. Distribution, extent of wall motion abnormalities and mean number of total involved segments were similar between patients with AS-STEMI and those with EA-STEMI (p > 0.05). Regarding regional dysfunction, the apical septal (99.1% vs. 92.2%, p < 0.05) and apical (76.4% vs. 60.0%, p < 0.05) segments were the only two segments that were affected significantly more in patients with EA-STEMI than in patients with AS-STEMI. So, the term AS-STEMI may be a misnomer, as it implies that only the anteroseptal segments of the left ventricle are involved. This study shows that regional dysfunction in patients with AS-STEMI extends beyond the anteroseptal region. So, any patients with anterior wall involvement, either anteroseptal or extensive anterior STEMI, should be treated with equal importance.

Expanding tuberculosis case notification among marginalized groups in Bangladesh through peer sputum collection

Case notification rates of tuberculosis (TB) in Bangladesh remain poor despite a high burden of disease. Peer sputum collection among underserved populations was implemented to expand case notification and to provide socially empowering roles in society for often excluded members of marginalized populations. Over the 55 months of the evaluation, 32 587 members of key populations were screened for TB, with 1587 smear-positive TB cases detected. Broadening TB services at human immunodeficiency virus drop-in centers using peer sputum collection to target high-risk populations for TB may be an effective way to increase TB case notification among key populations in Bangladesh.

Morphometric study of dentate nucleus of cerebellum in Bangladeshi cadaver

This cross sectional descriptive study was done by using nonprobability sampling technique and performed by examining 63 (sixty three) cerebellum. Out of them 40 postmortem human cerebellum collected from Bangladeshi cadavers of both sexes (male 25 and female 15) age ranging from 5 to 60 years and 23 cerebellums from caesarian section of intrauterine death cases of both sexes (male 14 and female 9) age ranging from 34 to 41 weeks of gestation. Specimens were collected from dead bodies autopsied on different dates from April' 2009 to September' 2009 at the autopsy laboratory of department of Forensic Medicine and prenatal cases from Gynaecology and Obstetrics Department of Mymensingh Medical College, Mymensingh. The collected specimens were grouped into three age groups like Group A (28 to 42 weeks of gestation), Group B (5 to 30 years) and Group C (31 to 60 years) and, two sex groups (male and female) and two sides (right and left). A transverse section was made at the level of horizontal fissure, and length and breadth of dentate nucleus were measured by divider and scale. The mean (±SD) length and breadth of dentate nucleus was 8.619±2.995mm and 14.770±3.604mm respectively and it was observed that length and breadth of dentate nucleus increased with age upto certain level then slightly decreased in the late age Group C. In this study, differences of the mean length of dentate nucleus on both right and left sides were statistically moderately significant between age Groups A&B. The differences of mean breadth of dentate nucleus on both right and left side were statistically highly significant between age Groups A&B and moderately significant between age Groups A&C on right side and only significant on left side. The differences between male & female were statistically insignificant in length and breadth of dentate nucleus.

Molecular-like hierarchical self-assembly of monolayers of mixtures of particles

We present a technique that uses an externally applied electric field to self-assemble monolayers of mixtures of particles into molecular-like hierarchical arrangements on fluid-liquid interfaces. The arrangements consist of composite particles (analogous to molecules) which are arranged in a pattern. The structure of a composite particle depends on factors such as the relative sizes of the particles and their polarizabilities, and the electric field intensity. If the particles sizes differ by a factor of two or more, the composite particle has a larger particle at its core and several smaller particles form a ring around it. The number of particles in the ring and the spacing between the composite particles depend on their polarizabilities and the electric field intensity. Approximately same sized particles form chains (analogous to polymeric molecules) in which positively and negatively polarized particles alternate.

Urinary excretion of arsenic following rice consumption

Patterns of arsenic excretion were followed in a cohort (n = 6) eating a defined rice diet, 300 g per day d.wt. where arsenic speciation was characterized in cooked rice, following a period of abstinence from rice, and other high arsenic containing foods. A control group who did not consume rice were also monitored. The rice consumed in the study contained inorganic arsenic and dimethylarsinic acid (DMA) at a ratio of 1:1, yet the urine speciation was dominated by DMA (90%). At steady state (rice consumption/urinary excretion) ∼40% of rice derived arsenic was excreted via urine. By monitoring of each urine pass throughout the day it was observed that there was considerable variation (up to 13-fold) for an individual's total arsenic urine content, and that there was a time dependent variation in urinary total arsenic content. This calls into question the robustness of routinely used first pass/spot check urine sampling for arsenic analysis.

Supratentorial glioblastoma multiforme metastasizing to the cervical spinal cord

Cases of glioblastoma multiforme (GBM) metastasizing to the leptomeninges or the intramedullary spine are rare and their prognosis are relatively poor. We present a case of supratentorial glioblastoma WHO grade IV which was later diagnosed to have cervical intramedullary metastasis 7 months after the primary surgery.

Evaluation of outcome of surgical excision of the nidus of osteoid osteoma of long bone

Osteoid osteoma is a benign bone tumour usually found in the lower extremities of children and young adults. This tiny bone tumour causes pain out of all proportion to its size and hinders the daily activities. This Quasi-experimental study conducted in the department of Orthopaedic surgery of BSMMU from January 2008 to December 2009. Twenty one patients were included in the study where purposive sampling technique was used on the basis of inclusion and exclusion criteria and all the ethical conditions were fulfilled. Diagnosis was almost obtained by taking history, clinical examination, and relevant investigations. Clinical variables were age, sex, site, pain, swelling, deformity and outcome variables were painless active life, removal of swelling, prevention of deformity, rate of recurrence. After localization of the tumour with the help of C arm, the nidus was excised in a small block of bone. The outcome is categorized by consensus, as clinically successful, only if the patient was free of pain and was taking no medication. The treatment was considered to have failed if a subsequent procedure had been performed to remove tumour. Among 21 cases, 14(66.7%) were male and 7(33.7%) were female. Maximum number of patients 15(71.4%) was between 10 years to 20 years. Most of the patients (76.2%) affected by osteoid osteoma were young students and most of the patients (95.2%) experienced moderate aching pain, usually aggravating at night which was typically relieved by aspirin or other NSAIDs (71.4%). Lower limbs (76.2%) particularly femur and tibia were commonly affected. Out of 21 patients, 19(90.5%) patients have got immediate pain relief or required no medication. In only 2 patients (9.5%), subsequent procedure has been performed to relief pain. So, successful outcome (in 19 out of 21) was significantly (p<0.001) higher in comparison to failed. Surgical excision of the nidus is a simple and easy procedure and does not require extensive resection of bone. If localization is done properly success rate is high and patients can return to normal daily activities.
