Epithelioid hemangioendothelioma in pleural effusion

Epithelioid hemangioendothelioma (EHE) is a rare mesenchymal tumor of vascular origin with variable morphological features and unpredictable biological behavior. EHE occasionally involves the pleural fluid. However, the cytomorphology of EHE found in pleural fluid has not been well characterized in the literature. Herein we describe a case of EHE, initially presenting as multiple liver lesions plus several small nodular densities at the bases of the lungs followed by bilateral pleural effusions. Diagn.

Mother's dietary diversity and association with stunting among children <2 years old in a low socio‐economic environment: A case–control study in an urban care setting in Dhaka,Bangladesh

Mothers are often responsible for preparing nutritious foods in their households. However, the quality of mother's diets is often neglected, which may affect both mother's and child's nutrition. Because no single food contains all necessary nutrients, diversity in dietary sources is needed to ensure a quality diet. We aimed to study the association between mother's dietary diversity and stunting in children <2 years attending Dhaka Hospital of icddr,b, a diarrhoeal disease hospital in Dhaka, Bangladesh. A case–control study (n = 296) was conducted from November 2016 to February 2017. Data were collected from mothers of stunted children <2 years (length‐for‐age z score [LAZ] < ?2) as “cases” and nonstunted (LAZ ≥ ?1) children <2 years as “controls.” Mothers were asked to recall consumption of 10 defined food groups 24 hr prior to the interview as per Guidelines for Minimum Dietary Diversity for Women. Among the mothers of cases, 58% consumed <5 food groups during the last 24 hr, compared with 45% in control mothers (P = 0.03). Children whose mothers consumed <5 food groups were 1.7 times more likely to be stunted than children whose mothers consumed ≥5 food groups (P = 0.04). Intake of food groups such as pulses, dairy, eggs, and vitamin A rich fruit was higher in control mothers. Proportion of mother's illiteracy, short stature, monthly family income <BDT 11,480, absence of bank account, and poor sanitation was also found to be higher in stunted group. Further study particularly intervention or longitudinal study to see the causality of mother's dietary diversity with child stunting is recommended.     

Novel mutation in FOXC1 wing region causing Axenfeld-Rieger anomaly

PURPOSE: To determine the possible molecular genetic defect underlying Axenfeld-Rieger anomaly (ARA) and to identify the pathogenic mutation causing this anterior segment dysgenesis in an Indian pedigree. METHODS: The FOXC1 gene was amplified from genomic DNA of members of an ARA-affected family and control subjects using four novel sets of primers. The amplicons were directly sequenced, and the sequences were analyzed to identify the disease-causing mutation. RESULTS: A heterozygous novel missense mutation was identified in the coding region of the FOXC1 gene in all three patients in this family. Consistent with the autosomal dominant inheritance pattern, the mutation segregated with the disease phenotype and was fully penetrant. The mutation was found in the wing region of the highly conserved forkhead domain of the FOXC1 gene and resulted in a very severe phenotype leading to blindness. CONCLUSIONS: This is the first study to demonstrate that a mutation in the FOXC1 wing region can cause an anterior segment dysgenesis of the eye. This mutation resulted in blindness in the ARA-affected family, and the findings suggest that the FOXC1 wing region has a functional role in the normal development of the eye. Moreover, this is the first study from India to report the genetic etiology of Axenfeld-Rieger anomaly. Genotype-phenotype correlations of FOXC1 may help in establishing the disease prognosis and also in understanding the clinical and genetic heterogeneity associated with various anterior segment dysgenesis caused by this gene.     

Mutational analysis of the RB1 gene in Indian patients with retinoblastoma

Twenty-one probands, twelve with bilateral and nine with unilateral retinoblastoma, were screened for mutations in the RB1 gene using genomic DNA from peripheral blood leukocytes as well as tumors. Amplification of individual exons and flanking regions of the RB1 gene were carried out, followed by direct sequencing of the amplified products. Sequences of affected individuals were compared with those of controls. Mutations were identified in seven patients, five with bilateral and two with unilateral retinoblastoma. Six out of seven mutations involved the formation of premature termination codons by means of single base substitutions (2), frameshifts due to splice-site mutations (2), or deletion and duplication (2). One missense mutation was identified. Of the remaining fourteen patients, seven with bilateral disease had no mutations in peripheral blood (7 cases) or tumors (3/7 cases). Analysis of the peripheral blood of seven patients with unilateral disease also showed no mutations. Mutations were detected in about one-third of the cases, suggesting that hemizygous deletions at the RB1 locus or mutations outside the coding regions of RB1 may be responsible for the disease in the remaining patients.     

Inter-rater reliability of the Brazilian version of the Paykel scale of stressful life events

The inter-rater reliability of the Brazilian version of the Recent Life Events Interview, developed by Paykel in order to evaluate stressful life events, was studied in 21 psychiatric inpatients and 20 psychiatric outpatients. Data concerning the agreement between the two raters showed a satisfactory reliability for specific occurrence of events, month of occurrence, independence of events and negative objective impact. This preliminary study suggests that the Brazilian version of the Recent Life Events Interview is a reliable instrument for the assessment of life events in Brazilian samples.     

The algogenic-induced nociceptive flexion test in mice: studies on sensitivity of the test and stress on animals

Recently we developed a new technique, known as peripheral nociception test or algogenic-induced nociceptive flexion (ANF) test, to study the in vivo signal transduction of pain at the peripheral nerve endings in mice. In the present report, we examined the sensitivity of the method to detect pain signal and the stresses induced by the test on experimental animals. In the algogenic-induced biting and licking (ABL) test, bradykinin could not induce significant biting-licking response even at a dose of 1nmol. It induced significant biting-licking response only at 10nmol. However, with the ANF test, 100fmol of bradykinin was enough to produce sharp and significant nociceptive flexion response. Similarly, substance P, ATP and ONO-54918-07, a stable prostaglandin I(2) agonist, induced nociceptive flexion response in ANF test at much lower doses than needed to induce biting-licking responses in ABL test. Next, we measured the plasma corticosterone level after different nociception tests, which is a measure of stress on animals due to experimental manipulations. However, no significant rise in corticosterone level was observed with ANF test. Altogether, these findings indicate that the ANF test is a highly sensitive and less stressful technique to study in vivo mechanisms of pain at the peripheral nerve ending.     

Zinc in CSF of patients with febrile convulsion

OBJECTIVE: This prospective study was carried out from July-December 1999 to see the status of zinc in CSF of children with febrile convulsion and to compare this to that of control. METHODS: Forty-two cases of febrile convulsion and 30 controls (fever without convulsion) were enrolled into the study. CSF zinc was estimated by atomic absorption spectrophotometry (AAS) in Atomic Energy Center, Dhaka and compared between the two groups. RESULTS: The mean zinc level in CSF in the study sample was 40.19mgm/L and that in control was 74.98mgm/L. This difference was statistically significant (p<0.001). CONCLUSION: The study concludes that a significantly lower of zinc exists in CSF of children with febrile. However no relationship was found between CSF zinc status with age, sex, degree & duration of fever and time of lumbar puncture after convulsion.     

Aspirin and statin medication decreases the risk of myocardial infarction associated with LTA and NFKBIL1 polymorphisms

Lymphotoxin-α (LTA) is a cytokine involved in inflammatory reactions. NFKBIL1 is a regulator of the NF-κB complex. The study investigated the associations of LTA 804 C>A and NFKBIL1-63 T>A polymorphisms with the use of statin and acetylsalicylic acid (ASA) treatment in relation to myocardial infarction (MI). The study population comprised of 600 Finnish individuals who underwent coronary angiography volunteering for the Angiography and Genes Study. Genotypes were detected by the TaqMan 5′ nuclease assay. We found a interaction between the LTA genotype (p=0.002) and the NFKBIL1 genotype (p=0.012) and statin treatment in relation to MI. Subjects with the LTA AA or the NFKBIL1 AA genotype were at a 2.77 (95% CI:1.22-6.24) and 2.85 (95% CI:1.22-6.66) times higher risk, respectively, of suffering an MI when compared to other genotypes among statin non-users. ASA treatment also modulated associations between LTA and NFKBIL1 genotypes and MI (p=0.015 and p=0.028 respectively). The NFKBIL1-A-LTA-A haplotype showed a 61% increase in the risk of MI compared to the NFKBIL1-T-LTA-C haplotype among statin non-users. Anti-inflammatory medication modifies the genotype-related risk of MI, suggesting that subjects with LTA and NFKBIL1 AA haplotype might especially benefit from the treatment.
