Awareness of eclampsia among rural tribal women of reproductive age

BACKGROUND

Globally, eclampsia is the leading cause of maternal and neonatal morbidity and mortality.

OBJECTIVE

The present community-based study was conducted among rural tribal women of reproductive age in remote villages of central India to determine their awareness of eclampsia and its likely impact.

METHODS

This cross-sectional analytic study included randomly selected 4500 tribal women, between 15 and 45 years of age, residing in 140 villages in the proximity of one village with a health facility (study center), and who were willing to undergo a personal interview. In-depth face-to-face interviews (each lasting 15-30 min) of study subjects regarding awareness, knowledge, practices, and perceptions about eclampsia were conducted using a predesigned tool completed by research assistants (not the subjects).

RESULTS

Of the 4500 women interviewed, the majority (62.4%) were 20-29 years old, minimally educated (40.6%), laborers (41.3%), and of a low socioeconomic class (40.8%). Of all the participants, only 35.9% were aware of eclampsia, associated events during pregnancy, labor, and the immediate post-delivery period; 81.7% of those who were aware understood about symptoms and signs like headache, blurring of vision, dizziness, swelling over the body, ad high blood pressure. Of all the women who knew about eclampsia, 73.9% were aware that the occurrence of convulsions during antenatal and postnatal periods was an emergency and required urgent management, whereas 88.4% were not aware that severe convulsions affected maternal and neonatal health seriously, only 38.2% knew that eclampsia was a preventable condition.

CONCLUSION

There was lack of awareness about eclampsia in many women and, of those who knew, some were not aware that it was dangerous. There is a need for awareness among women and their families of the disorder, its impact, and what action is needed in case it occurs.

The Blunt Liver and Spleen Trauma (BLAST) audit: national survey and prospective audit of children with blunt liver and spleen trauma in major trauma centres

PURPOSE

To compare the reported and observed management of UK children with blunt liver or spleen injury (BLSI) to the American Pediatric Surgical Association (APSA) 2019 BLSI guidance.

METHODS

UK Paediatric Major Trauma Centres (pMTCs) undertook 1 year of prospective data collection on children admitted to or discussed with those centres with BLSI and an online questionnaire was distributed to all consultants who care for children with BLSI in those centres.

RESULTS

All 21/21 (100%) pMTCs participated; 131 patients were included and 100/152 (65%) consultants responded to the survey. ICU care was reported and observed to be primarily determined using haemodynamic status or concomitant injuries rather than injury grade, in accordance with APSA guidance. Bed rest was reported to be determined by grade of injury by 63% of survey respondents and observed in a similar proportion of patients. Contrary to APSA guidance, follow-up radiological assessment of the injured spleen or liver was undertaken in 44% of patients before discharge and 32% after discharge, the majority of whom were asymptomatic.

CONCLUSIONS

UK management of BLSI differs from many aspects of APSA guidance. A shift towards using clinical features to determine ICU admission and readiness for discharge is demonstrated, in line with a strong evidence base. However, routine bed rest and re-imaging after BLSI is common, contrary to APSA guidance. This disparity may exist due to concern that evidence around the incidence, presentation and natural history of complications after conservatively managed BLSI, particularly bleeding from pseudoaneurysms, is weak.

Neuroanatomical changes of ionotropic glutamatergic and GABAergic receptor densities in male mice modeling idiopathic and syndromic autism spectrum disorder

Autism spectrum disorder (ASD) comprises a wide range of neurodevelopment conditions primarily characterized by impaired social interaction and repetitive behavior, accompanied by a variable degree of neuropsychiatric characteristics. Synaptic dysfunction is undertaken as one of the key underlying mechanisms in understanding the pathophysiology of ASD. The excitatory/inhibitory (E/I) hypothesis is one of the most widely held theories for its pathogenesis. Shifts in E/I balance have been proven in several ASD models. In this study, we investigated three mouse lines recapitulating both idiopathic (the BTBR strain) and genetic (Fmr1 and Shank3 mutants) forms of ASD at late infancy and early adulthood. Using receptor autoradiography for ionotropic excitatory (AMPA and NMDA) and inhibitory (GABAA) receptors, we mapped the receptor binding densities in brain regions known to be associated with ASD such as prefrontal cortex, dorsal and ventral striatum, dorsal hippocampus, and cerebellum. The individual mouse lines investigated show specific alterations in excitatory ionotropic receptor density, which might be accounted as specific hallmark of each individual line. Across all the models investigated, we found an increased binding density to GABAA receptors at adulthood in the dorsal hippocampus. Interestingly, reduction in the GABAA receptor binding density was observed in the cerebellum. Altogether, our findings suggest that E/I disbalance individually affects several brain regions in ASD mouse models and that alterations in GABAergic transmission might be accounted as unifying factor.

Evaluation of ultrasound airway assessment parameters in pregnant patients and their comparison with that of non-pregnant women: a prospective cohort study

BACKGROUND

Clinical airway assessment parameters differ significantly between pregnant and non-pregnant patients, however literature comparing their ultrasound (US) airway parameters is limited. We planned a prospective cohort study to compare US-assessed airway parameters between pregnant and non-pregnant women.

METHODS

We enrolled 82 pregnant females scheduled for elective cesarean section under neuraxial anesthesia and 80 age-matched non-pregnant females scheduled for elective surgery. Pre-operative clinical airway assessment was performed in both groups. The US airway assessment was done pre-operatively in non-pregnant and postoperatively in pregnant patients. Our primary objective was to compare US-assessed parameters, and secondary objectives included a comparison of clinical airway assessment parameters and investigating a relationship between a difficult airway (defined as a modified Mallampati grade (MMG) ≥ 3) and other airway assessment parameters.

RESULTS

Among several US airway parameters, pregnant patients had significantly higher hyomental distance, anterior neck soft tissue thickness at the hyoid and vocal cord level, and oral cavity height, while the tongue thickness and mandibular condylar movements were significantly lower than in non-pregnant patients. Similarly, for the clinical airway assessment, pregnant patients had significantly higher MMG and upper lip bite test scores, mentohyoid distance, and neck circumference. Pregnancy, the ratio of pre-epiglottic space and epiglottis-to-vocal cords distance (Pre-E/E-VC), and hyoid bone visibility were independent predictors of a difficult airway.

CONCLUSION

The US airway assessment parameters differ significantly between pregnant and non-pregnant patients. Pregnancy, hyoid bone visibility, and Pre-E/E-VC ratio were independent predictors of the difficult airway in female patients.

Striatal increase of dopamine receptor 2 density in idiopathic and syndromic mouse models of autism spectrum disorder

Autism spectrum disorder (ASD) comprises a wide range of neurodevelopmental phenotypes united by impaired social interaction and repetitive behavior. Environmental and genetic factors are associated with the pathogenesis of ASD, while other cases are classified as idiopathic. The dopaminergic system has a profound impact in the modulation of motor and reward-motivated behaviors, and defects in dopaminergic circuits are implicated in ASD. In our study, we compare three well-established mouse models of ASD, one idiopathic, the BTBR strain, and two syndromic, Fmr1 and Shank3 mutants. In these models, and in humans with ASD, alterations in dopaminergic metabolism and neurotransmission were highlighted. Still, accurate knowledge about the distribution of dopamine receptor densities in the basal ganglia is lacking. Using receptor autoradiography, we describe the neuroanatomical distribution of D1 and D2 receptors in dorsal and ventral striatum at late infancy and adulthood in the above-mentioned models. We show that D1 receptor binding density is different among the models irrespective of the region. A significant convergence in increased D2 receptor binding density in the ventral striatum at adulthood becomes apparent in BTBR and Shank3 lines, and a similar trend was observed in the Fmr1 line. Altogether, our results confirm the involvement of the dopaminergic system, showing defined alterations in dopamine receptor binding density in three well-established ASD lines, which may provide a plausible explanation to some of the prevalent traits of ASD. Moreover, our study provides a neuroanatomical framework to explain the utilization of D2-acting drugs such as Risperidone and Aripiprazole in ASD.

Pre-Transplant Marital Status and Hematopoietic Cell Transplantation Outcomes

Background

Evidence about the impact of marital status before hematopoietic cell transplantation (hct) on outcomes after hct is conflicting.

Methods

We identified patients 40 years of age and older within the Center for International Blood and Marrow Transplant Research registry who underwent hct between January 2008 and December 2015. Marital status before hct was declared as one of: married or living with a partner, single (never married), separated or divorced, and widowed. We performed a multivariable analysis to determine the association of marital status with outcomes after hct.

Results

We identified 10,226 allogeneic and 5714 autologous hct cases with, respectively, a median follow-up of 37 months (range: 1-102 months) and 40 months (range: 1-106 months). No association between marital status and overall survival was observed in either the allogeneic (p = 0.58) or autologous (p = 0.17) setting. However, marital status was associated with grades 2-4 acute graft-versus-host disease (gvhd), p < 0.001, and chronic gvhd, p = 0.04. The risk of grades 2-4 acute gvhd was increased in separated compared with married patients [hazard ratio (hr): 1.13; 95% confidence interval (ci): 1.03 to 1.24], and single patients had a reduced risk of grades 2-4 acute gvhd (hr: 0.87; 95% ci: 0.77 to 0.98). The risk of chronic gvhd was lower in widowed compared with married patients (hr: 0.82; 95% ci: 0.67 to 0.99).

Conclusions

Overall survival after hct is not influenced by marital status, but associations were evident between marital status and grades 2-4 acute and chronic gvhd. To better appreciate the effects of marital status and social support, future research should consider using validated scales to measure social support and patient and caregiver reports of caregiver commitment, and to assess health-related quality of life together with health care utilization.

Unusual presentation of intussusception: Gallstone ileus

Gallstone ileus is a rare pathology, occurring in an estimated 0.5% of cases, which preferentially affect females and the elderly population. This rare pathology is the result of a fistulous connection between the bowel and gallbladder. This connection allows gallstones to pass into the bowel leading to mechanical obstruction. On rare occasions the enteric gallstone can act as a lead point causing intussusception. We present a rare case of intussusception secondary to gallstone ileus in a young, relatively asymptomatic patient. CT played a critical role in diagnosis and appropriate management of our patient.

Atypical theileriosis with cutaneous involvement in a cow in India: a case report

Bovine tropical theileriosis caused by Theileria annulata is an overwhelming haemoprotozoan tick-borne disease in taurine and cross-bred cattle in Punjab, India. However, there seems to be no report from India of cutaneous nodules associated with the disease. This report describes a five-year-old cross-bred cow presented to a university clinic with a history of fever, inappetence and malaise for the past six to seven days. Clinical examination revealed normal vital parameters, pale mucous membranes, mild enlargement of the prescapular lymph nodes and multiple subcutaneous nodular masses (2-4 cm) on the neck and abdomen. Haematology revealed mild anaemia and leucopenia with 48% neutrophils, 48% lymphocytes and 4% eosinophils. Romanowsky-stained smears of fineneedle aspiration biopsy samples from swollen lymph nodes and subcutaneous masses showed an increased number of lymphoid cells, suggesting cutaneous lymphomatosis. However, a critical examination of the smears from subcutaneous nodules showed a large number of Koch's blue bodies in macrophages and lymphoblasts, and several piroplasms were also noticed within the red blood cells in lymph node smears. A peripheral blood smear revealed mild to moderate parasitaemia. Extracted DNA from the parasitologically positive blood sample was subjected to nested polymerase chain reaction (nPCR) using T. annulata speciesspecific primers encoding the 30-kiloDalton major sporozoite surface antigen. The desired 572-base pair amplified product of the nPCR was comparable to the positive control. This seems to be a rare case of T. annulata in an adult cross-bred cow, showing cutaneous nodular involvement.

Parental decisional satisfaction after hypospadias repair in the United Kingdom

BACKGROUND

In hypospadias, the aim of surgical treatment is to achieve both desirable functional and cosmetic outcomes; however, complications following surgery are common and 18% of boys require re-operation. In mild degrees of hypospadias, repair may be offered entirely to improve cosmesis, meaning parents should be fully informed of this and the potential for complications, during the consent process. Parents' decision-making may be aided by making them aware of how others in a similar position have felt about the decision that they made for their child. One method of measuring parental satisfaction is decisional regret (DR).

OBJECTIVES

To assess parental satisfaction following hypospadias surgery in the United Kingdom by assessing DR and to determine the feasibility of obtaining meaningful data via a mobile phone survey.

STUDY DESIGN

The National Outcomes Audit in Hypospadias database was commissioned by the British Association of Paediatric Surgeons to capture clinical information from hypospadias repairs. Following ethical approval (16/NW/0819), a text message was sent to mobile numbers in the database inviting participation in a questionnaire incorporating the validated DR scale (DRS). The primary outcome measure was mean DRS score, which was correlated with clinical information, a score of zero indicated no regret and 100 indicated maximum regret.

RESULTS

There were 340 (37%) responses. The median age at the primary procedure was 16 (interquartile range 13-20) months. No DR (score = 0) was detected in 186 (55% [95%CI 49-60]) respondents; however, moderate-to-severe DR (score = 26-100) was seen in 21 (6.2% [95%CI 3.6-8.7]) respondents. On multivariate analysis, a distal meatus, a small glans and developing complications requiring repeat surgery were all associated with increased levels of regret (Table). There was no association between DR and cases performed per surgeon.

DISCUSSION

Around half of respondents demonstrated no DR and postoperative complications requiring surgery were associated with the highest levels of DR, which is similar to a Canadian study. Lorenzo et al. however found that DR was associated with circumcision, which was undertaken in all boys; however, in this UK study, around a third of boys were circumcised and regret levels between those circumcised and those not circumcised were similar. The limitations of this work include the following: surgeons submitting their own data on complications and there is potential of selection bias between respondents and non-respondents as with any survey.

CONCLUSIONS

Data from this study can be used to improve pre-operative counselling during the consent process. Smart mobile phone technology can be used successfully to distribute and collect parent-reported outcomes.

In this review, we discuss the concept and nature of functional foods, the constituents or ingredients that are commonly used to fortify these foods, and the purpose of fortification. Finally, the review surveys consumers� attitudes toward functional foods and their importance to help their development and marketing.

Choosing The Right Animal Model for Renal Cancer Research

The increase in the life expectancy of patients with renal cell carcinoma (RCC) in the last decade is due to changes that have occurred in the area of preclinical studies. Understanding cancer pathophysiology and the emergence of new therapeutic options, including immunotherapy, would not be possible without proper research. Before new approaches to disease treatment are developed and introduced into clinical practice they must be preceded by preclinical tests, in which animal studies play a significant role. This review describes the progress in animal model development in kidney cancer research starting from the oldest syngeneic or chemically-induced models, through genetically modified mice, finally to xenograft, especially patient-derived, avatar and humanized mouse models. As there are a number of subtypes of RCC, our aim is to help to choose the right animal model for a particular kidney cancer subtype. The data on genetic backgrounds, biochemical parameters, histology, different stages of carcinogenesis and metastasis in various animal models of RCC as well as their translational relevance are summarized. Moreover, we shed some light on imaging methods, which can help define tumor microstructure, assist in the analysis of its metabolic changes and track metastasis development.

E6AP inhibits G-CSFR turnover and functions by promoting its ubiquitin-dependent proteasome degradation

Granulocyte colony-stimulating factor receptor (G-CSFR) plays a crucial role in regulating myeloid cell survival, proliferation, and neutrophilic granulocyte precursor cells maturation. Previously, we demonstrated that Fbw7α negatively regulates G-CSFR and its downstream signaling through ubiquitin-proteasome mediated degradation. However, whether additional ubiquitin ligases for G-CSFR exist is not known. Identifying multiple E3 ubiquitin ligases for G-CSFR shall improve our understanding of activation and subsequent attenuation of G-CSFR signaling required for differentiation and proliferation. Here, for the first time we demonstrate that E6 associated protein (E6AP), an E3 ubiquitin ligase physically associates with G-CSFR and targets it for ubiquitin-mediated proteasome degradation and thereby attenuates its functions. We further show that E6AP promoted G-CSFR degradation leads to reduced phosphorylation of signal transducer and activator of transcription 3 (STAT3) which is required for G-CSF dependent granulocytic differentiation. More importantly, our finding shows that E6AP also targets mutant form of G-SCFR (G-CSFR-T718), frequently observed in severe congenital neutropenia (SCN) patients that very often culminate to AML, however, at a quite slower rate than wild type G-CSFR. In addition, our data showed that knockdown of E6AP restores G-CSFR and its signaling thereby promoting granulocytic differentiation. Collectively, our data demonstrates that E6AP facilitates ubiquitination and subsequent degradation of G-CSFR leading to attenuation of its downstream signaling and inhibition of granulocytic differentiation.

A unique case of Babesia gibsoni infected dog with paraplegia

A 4 year old male Rottweiler was presented to Teaching Veterinary Clinics of GADVASU with a primary complaint of paraplegia, fever and inappetence. The dog was found to be dull with elevated rectal temperature (105 °F), heart rate (158 per minute) and respiration rate (57 per minute). Blood smear examination and PCR assay revealed that dog was positive for Babesia gibsoni. Elevated bilirubin, alanine aminotransferase, alkaline phosphatase, creatinine, total leucocyte count, neutrophils and hypoglycaemia were haemato-biochemical alterations. The therapy targeting babesiosis was carried out with a single dose of diminazene aceturate in combination with doxycycline, enrofloxacin and metronidazole for 21 days. Complete follow up of the case revealed complete clinical recovery within 21 days.

Meckel's diverticular perforation presenting as acute abdomen in the second trimester of pregnancy

Meckel's diverticular perforation is a rare cause of acute abdomen during pregnancy. We report the case of a 24-year-old woman at 24 weeks of gestation who presented with abdominal pain for 4 days accompanied with abdominal distension, tenderness and guarding in right lower quadrant. Ultrasonography was inconclusive. The patient underwent exploratory laparotomy with the clinical suspicion of appendicular perforation peritonitis. Intraoperatively, a perforated Meckel's diverticulum was detected. Owing to gross contamination of the peritoneal cavity, a diverticulectomy with ileostomy was performed. She had a normal full-term vaginal delivery, and ileostomy was reversed 1 month after delivery. The physiological and anatomical changes in pregnancy can make a straightforward clinical diagnosis difficult. A high index of suspicion is required to prevent delay in diagnosis and surgical intervention, which could prove detrimental to the mother and fetus.

Circulating T-helper 17 cells and associated cytokines in psoriasis

BACKGROUND

Recently, a new population of IL-17-producing CD4 T helper (Th) cells, named Th17, was identified and shown to be involved in various inflammatory and autoimmune diseases, including psoriasis.

AIM

To determine the frequency of Th17 cells and related cytokines in peripheral blood of patients with psoriasis, and to analyse their association with disease severity.

METHODS

This was a prospective study comprising 34 patients with psoriasis and 24 healthy controls. Clinicoepidemiological details of patients were recorded, and severity of psoriasis was assessed by means of the Psoriasis Area and Severity Index. Circulating Th1 and Th17 cells in untreated patients with psoriasis and healthy controls were quantified by flow cytometry. In sera collected from patients with psoriasis and healthy controls, concentrations of IL-17A and IL-23 were examined by ELISA.

RESULTS

Increased frequencies of CD4+ IL-17A+ T cells were seen in peripheral blood of patients with psoriasis vulgaris (P < 0.001). Although serum IL-17A and IL-23 concentrations were higher in patients with psoriasis than in controls, the results did not reach statistical significance. We could not find any correlation between the studied T cells or related cytokines and the disease severity.

CONCLUSION

Increased serum levels of circulating Th17 cells and related cytokines may contribute to the cutaneous pathology of psoriasis, as well as the inflammatory process that is a hallmark of psoriasis.

Identification of β-Amino alcohol grafted 1,4,5 trisubstituted 1,2,3-triazoles as potent antimalarial agents

In a quest to discover new drugs, we have synthesized a series of novel β-amino alcohol grafted 1,2,3-triazoles and screened them for their in vitro antiplasmodial and in vivo antimalarial activity. Among them, compounds 16 and 25 showed potent activity against chloroquine-sensitive (Pf3D7) strain with IC50 of 0.87 and 0.3 μM respectively, while compounds 7 and 13 exhibited better activity in vitro than the reference drug against chloroquine-resistance strain (PfK1) with IC50 of 0.5 μM each. Compound 25 showed 86.8% in vivo antimalarial efficacy with favorable pharmacokinetic parameters. Mechanistic studies divulged that potent compounds significantly boosted p53 protein levels to exhibit the antimalarial activity.

Trends of vulvar cancer

Vulvar cancer is an uncommon malignancy of the female genital tract in developing countries, accounting for 3% of gynaecological cancers. Here, cervical cancer is an everyday problem; ovarian cancer is the second commonest gynaecological cancer; endometrial is less common and vulvar cancer is rare. It is advanced at admission, though is a visible cancer. Records of women who had histopathologically proven vulvar cancer over 24 years were analysed for epidemiological status and preventive possibilities. During the analysis period, 9,419 total cancer cases were diagnosed; 4,726 (50.17%) were in women. A total of 39.52% (1,868 of 4,726) were gynaecological; 18 cases were vulvar (0.38% of the 4,726 women with cancer) and 0.96% of the 1,868 gynaecological cancer cases. Decreasing trends were 2.25% between 1984 and 1988, down to 0.33% between 2004 and 2008. Leading presenting complaints were: dyspareunia, 88.88% (16 of 18 patients); pruritus 13; ulcers 14; vulvar swelling 12 and urinary problems 13. Dystrophy was present in 8 of 18 cases. Overall, four had stage I, one stage II, three stage III and four stage IV disease at admission; all at labia majora or minora, some too advanced to know origin. Four women with metastasis in the lungs, liver and bones could only be given palliation. While vulvar cancer is uncommon, advanced disease at admission is a concern. Awareness is essential. Research is needed as to why cervical cancer is common and vulvar uncommon, as HPV plays a major aetiological role, so that cervical cancer can be prevented, with early diagnosis, management of vulvar cancer should also be available.

Compact, hydrophilic, lanthanide-binding tags for paramagnetic NMR spectroscopy

The design, synthesis and evaluation of four novel lanthanide-binding tags for paramagnetic NMR spectroscopy are reported.

The design, synthesis and evaluation of four novel lanthanide-binding tags for paramagnetic NMR spectroscopy are reported. Each tag is based on the ((2S,2′S,2′′S,2′′′S)-1,1′,1′′,1′′′-(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrayl)tetrakis(propan-2-ol)) scaffold, featuring small chiral alcohol coordinating pendants to minimise the size and hydrophobic character of each tag. The tags feature different linkers of variable length for conjugation to protein via a single cysteine residue. Each tag's ability to induce pseudocontact shifts (PCS) was assessed on a ubiquitin A28C mutant. Two enantiomeric tags of particular note, C7 and C8, produced significantly larger Δχ-tensors compared to a previously developed tag, C1, attributed to the extremely short linker utilised, limiting the mobility of the bound lanthanide ion. The C7 and C8 tags' capacity to induce PCSs was further demonstrated on GB1 Q32C and 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase (HPPK) S112C/C80A mutants. Whilst factors such as the choice of lanthanide ion, pH and site of conjugation influence the size of the PCSs obtained, the tags represent a significant advance in the field.

Impact of iron deficiency on hemoglobin A2% in obligate β-thalassemia heterozygotes

INTRODUCTION

The potential impact of concomitant iron deficiency on hemoglobin A2 (HbA2)-based identification of β-thalassemia trait (βTT) is a worrisome issue for screening laboratories. This is especially true for resource-constrained settings where iron deficiency is widespread and molecular confirmatory tests for borderline low HbA2 values may be unavailable.

METHODS

Obligate βTT carrier individuals (n = 752) were identified during screening studies on the parents of thalassemia major patients. HbA2%, complete blood counts and serum iron, ferritin and transferrin saturation were studied. Iron-deficient individuals (n = 135) with normal range HbA2% were taken as controls.

RESULTS

Concomitant iron deficiency (defined as ferritin ≤15 ng/mL and/or transferrin saturation ≤15%) was present in 20.7% (156/752) βTT cases, that is, 33.3% females (122/366) and 8.8% males with βTT (34/386). Mean HbA2 in iron-replete βTT was 5.4 ± 0.8 (range 3.1-7.9) and in iron-deficient βTT was 5.4 ± 0.9 (range 3.3-7.6). HbA2 < 4.0% was found in 23/752 (3.1%) βTT: 13/595 iron-replete (2.2%) and 10/157 (6.4%) iron-deficient βTT individuals. However, five of the 10 iron-deficient βTT cases carried the silent CAP+1 (A>C) β-thalassemia allele accounting for the borderline HbA2%. On a separate analysis, all five severely anemic βTT (Hb < 80 g/L) and 16/17 βTT with severe hypoferritinemia (<5 ng/mL) had HbA2 > 4.5%. The single case with serum ferritin 4.8 ng/mL and HbA2 3.3% showed a CAP+1 (A>C) mutation.

CONCLUSIONS

Iron deficiency was prevalent among north Indian βTT individuals, especially women. After adjusting for other causes of low HbA2 in βTT, iron deficiency, even when very severe, was very unlikely to interfere significantly with HbA2-based identification of βTT.

Histomorphometry of Umbilical Cord and its Vessels in Pre- Eclampsia as Compared to Normal Pregnancies

Aims: To study and compare the morphometric alteration in the umbilical cord obtained from thirty normal pregnancies (Group-I) and thirty pre-eclamptic pregnancies (Group-II). Methods: Morphological changes in umbilical cords were examined on formalin fixed paraffin embedded section. Various parameters were measured by planimeter. Results: In pre-eclamptic group total vessel area, total vein area, total luminal area of vein, and wall thickness of arteries were increased, whereas jelly area and wall thickness of vein were decreased as compared to normal group. Conclusion: Increased umbilical arterial thickness, decreased umbilical vein wall thickness and increased luminal area of vein which could be a predictor of intrauterine growth retardation in term pre-eclamptic patients. Nepal Journal of Obstetrics and Gynaecology / Vol 7 / No. 1 / Issue 13 / Jan- June, 2012 / 28-32 DOI: http://dx.doi.org/10.3126/njog.v7i1.8832

Memory binding in clinical and non-clinical psychotic experiences: how does the continuum model fare?

INTRODUCTION

Both clinical and non-clinical auditory hallucinations (AH) have been associated with source memory deficits, supporting a continuum of underlying cognitive mechanisms, though few studies have employed the same task in patient and nonpatient samples. Recent commentators have called for more debate on the continuum model of psychosis. Consequently, the current study investigated the continuity model of AH with reference to memory binding.

METHODS

We used an identical voice and word recognition memory task to assess binding in two separate studies of: (1) healthy hallucination-prone individuals and controls (30 high and 30 low scorers on the Launay-Slade Hallucination Scale-Revised) and (2) schizophrenia patient samples (32 with AH, 32 without AH) and 32 healthy controls.

RESULTS

There was no evidence of impaired binding in high hallucination-prone, compared to low hallucination-prone individuals. In contrast, individuals with schizophrenia (both with and without AH) had difficulties binding (remembering "who said what"), alongside difficulties remembering individual words and voices. Binding ability and memory for voices were also negatively linked to the loudness of hallucinated voices reported by patients with AH.

CONCLUSIONS

These findings suggest that different mechanisms may exist in clinical and non-clinical hallucinators, adding to the growing debate on the continuum model of psychotic symptoms.

Simultaneous triple point-of-care testing for HIV, syphilis and hepatitis B virus to prevent mother-to-child transmission in India

An innovative simultaneous triple point-of-care (STPOC) screening strategy for syphilis, hepatitis B and HIV with Determine(®) tests was offered to pregnant women presenting for antenatal care and evaluated for feasibility and preference in rural India. Of 1066 participants approached, 1046 consented, of which 1002 (96.0%) completed the strategy. Only 9% reported any history of testing in their current pregnancy. With STPOC screening, 989 women (98.7%) tested negative and 13 had preliminary positive results for infection. The total time taken was 45 minutes per participant. Mothers and infants were provided prophylaxis/treatment for HIV, syphilis and hepatitis B, with interventions initiated within 3-5 days. STPOC was preferred by 99.3% (95%CI: 98.8-99.8%) of participants, facilitated early simultaneous screening for the three infections, timely initiation of prophylaxis/treatment and was feasible in this rural setting. These data suggest that multiplexed STPOC screening for syphilis, hepatitis B and HIV in pregnancy would be desirable for women in rural India.

Late postpartum eclampsia

Studies lack data regarding incidence, risk factors, optimal treatment and outcome of postpartum eclampsia (PPE), convulsions within 7 days (mostly convulsions occur within 24 - 48 h) after delivery of fetus placenta. However, convulsions can occur late, up to 4 weeks. After 48 h, it is late PPE. Late postpartum eclampsia without preceding pre-eclampsia is rare and poses a diagnostic challenge. An observational study was carried out to find the frequency of PPE, late PPE and clinical profile for prediction/prevention of mortality. PPE cases were analysed from retrospective records and prospective cases. Of 39,050 births, 386 were eclampsia (0.98%); PPE 101 (26.1% eclampsia, 0.26% births); 14.85% were late PPE. Of PPE, 52 (51.48%) were diagnosed hypertensive disorders pre-delivery and 49 (48.51%) were de novo. Prior to convulsions, 56 (55.5%) had headaches, six (5.9%) visual disturbances; nine (8.9) dizziness; four (4.0%) epigastric pain; 18 (17.8%) had no complaints. Research needs to continue and quality care is essential.

Bilateral superficial ulnar artery with high origin from the axillary artery: its anatomy and clinical significance

The superficial ulnar artery (SUA) is a rare anatomical variant that usually arises either in the axilla or the arm and runs a superficial course in the forearm, enters the hand, and participates in the formation of superficial palmar arch. During the routine dissection of cadavers in the department of anatomy, whilst preparing the specimen for medical students, an unusual bilateral branch of the axillary artery was found in one of the cadavers: a rare variant of the artery known as SUA, which originates from the 2nd part of the axillary arteries of both sides. The SUA is a known anatomical variant, but the bilateral high origin from the 2nd part of the axillary artery is extremely unusual. Its occurrence is of great clinical importance to the surgical and radiological departments.

Recurrent bilateral TMJ dislocation in a 20-month-old child: a rare case presentation

Temporomandibular joint dislocations are extremely rare in children and only four such cases have been reported in the literature so far. However, a case of recurrent bilateral mandibular dislocation is even rare to occur and a report of one such case is presented in this article.

Role of myofibroblasts and collagen type IV in patients of IgA nephropathy as markers of renal dysfunction

The aim was to evaluate the role of a-smooth muscle actin (SMA) and collagen type IV as markers of chronicity in renal biopsies of IgA nephropathy patients and to correlate the degree of their interstitial expression with renal function as judged by serum creatinine. Renal biopsies from 29 clinically, histologically and immunologically confirmed cases of IgA nephropathy were reviewed to assess activity and chronicity indices. Immunohistochemical stains for α-SMA and collagen type IV was performed on 23 patients with adequate tissue available in the block. The interstitial expression of α-SMA and collagen type IV was then correlated with chronicity and activity indices, serum creatinine and 24 hours urinary protein. Pearson's coefficient of correlation, unpaired-t test were used for statistical analysis. α-SMA and collagen type IV were shown to be expressed in the interstitium in all 22 cases showing interstitital fibrosis. Both showed a similar distribution pattern with predominant periglomerular and peritubular positivity. The cases were divided into two groups (low and high grade) depending on the percentage of interstitial area showing positivity for these two antibodies. On statistical analysis, the expression of both a-smooth muscle actin and collagen type IV showed a striking correlation with the histological chronicity index (P<0.01). A positive correlation was also noted with the serum creatinine at the time of diagnosis. It is seen that an immunohistochemical approach to grading interstitial fibrosis as in this study is far simpler than the histological grading systems prevalent and is an important baseline prognostic indicator.

Loss of the Parkinson's disease-linked gene DJ-1 perturbs mitochondrial dynamics

Growing evidence highlights a role for mitochondrial dysfunction and oxidative stress as underlying contributors to Parkinson's disease (PD) pathogenesis. DJ-1 (PARK7) is a recently identified recessive familial PD gene. Its loss leads to increased susceptibility of neurons to oxidative stress and death. However, its mechanism of action is not fully understood. Presently, we report that DJ-1 deficiency in cell lines, cultured neurons, mouse brain and lymphoblast cells derived from DJ-1 patients display aberrant mitochondrial morphology. We also show that these DJ-1-dependent mitochondrial defects contribute to oxidative stress-induced sensitivity to cell death since reversal of this fragmented mitochondrial phenotype abrogates neuronal cell death. Reactive oxygen species (ROS) appear to play a critical role in the observed defects, as ROS scavengers rescue the phenotype and mitochondria isolated from DJ-1 deficient animals produce more ROS compared with control. Importantly, the aberrant mitochondrial phenotype can be rescued by the expression of Pink1 and Parkin, two PD-linked genes involved in regulating mitochondrial dynamics and quality control. Finally, we show that DJ-1 deficiency leads to altered autophagy in murine and human cells. Our findings define a mechanism by which the DJ-1-dependent mitochondrial defects contribute to the increased sensitivity to oxidative stress-induced cell death that has been previously reported.

Pelvic tuberculosis continues to be a disease of dilemma--case series

Tuberculosis (TB) has become a global epidemic again with emergence of HIV/AIDS and multi-drug resistant strains of TB. Female genital tuberculosis (GT) is typically a disease of young women and its occurrence in post menopausal women is rare. Amongst the genital disorders, GT is the most baffling especially because of its various presentations. So GT is notorious for evading diagnosis. A series of cases of females GT between the age 25 yrs to 40 yrs is being reported with women having spectrum of clinical features, creating diagnostic dilemma and so final diagnosis by histopathology after laparotomy. So a high degree of suspicion aided by intensive investigations may be required for the diagnosis of GT. Medical therapy is the main treatment, however some do need surgery. Research needs to be continued for early establishment of timely diagnosis of GT and modalities of effective therapies.

Social issues around advanced unwanted pregnancies in rural single women

SUMMARY

This study covers issues on advanced unwanted pregnancies in rural single women in South-east Asia, with reference to age, education, occupation, person responsible (i.e. baby's father) and reasons for delay in seeking assistance. It describes single women with pregnancy beyond the time for abortion, as set by the Indian abortion law. The study involved 314 girls/women and was set in the Mahatma Gandhi Institute of Medical Sciences, Sevagram, India. The girls/women were admitted, provided with free facilities and had their babies looked after by hospital staff until given up for adoption, or otherwise. The outcomes of the study showed that most individuals (71.01%) were rural, less-literate, working girls. In 94.26% of cases, the baby's father was known; 24 (7.64%) reported rape (13 by a known person). A total of 66 individuals (21.02%) did not inform their parents about the pregnancy for up to 5 months. Five (1.59%) went to unqualified medical practitioners and 16.56% to private practitioners who did not give their services. A total of 47 (14.96%) had waited for the person responsible for their pregnancy before seeking assistance. There was a total of 315 babies born to 310 mothers (five twins); four absconded undelivered; 13 absconded after delivery (two with their babies, 11 leaving babies). The study found that pregnancies were often caused by rape and girls/women with no knowledge of abortion laws, shyness, fear, lack of desired privacy, lack of resources, misleading management at periphery all went beyond 20 weeks. Mostly, the babies were not accepted--the girls married the babies' fathers, but left their babies. Emergency contraception for unprotected sexual intercourse is essential.

Persistence of fruitless caesarean sections in Indian rural women

Caesarean section is one of the commonest major surgical procedures in public and private hospitals. The worldwide rise in the caesarean section rate during the last 50 years is cause for alarm and a matter of concern. This increase deserves international attention not only because of health consequences, resource administration and policies, but also because high caesarean section rates are not associated with low perinatal mortality rates. The present study is an analysis of indications of caesarean sections performed with no take-home baby ('fruitless' caesarean section) between April 1983 and March 2007. It was revealed that the caesarean section rate has increased from 15.47% of births in 1983 to 37.96% births in 2007, and 03.75% of these were fruitless. The overall perinatal mortality rate has reduced from 91.56 in 1983 to 51.20 in 2007, for various reasons. This analysis reveals a large increase in caesarean sections with many being fruitless. While the major causes of perinatal mortality were sepsis, prematurity and congenital anomalies which need to be addressed, it is also essential to review the indications of caesarean section, so as to prevent fruitless caesarean sections.

Gender and sufferings

The World Health Organization describes violence against women, as the most pervasive yet least recognised human rights abuse which cuts across geographical, racial, social and economic boundaries in the world. In the present study of the 2000 women interviewed, nearly 50% reported having been physically assaulted. Age, education or socioeconomic status did not change anything but more women from nuclear families were assaulted (52%) compared with other group. Some 68% of women were assaulted by husbands and 7% by multiple perpetrators. The reasons for assault varied. Nearly 60% of those assaulted had informed someone and in around 65% of cases someone had tried to help, but in only 50% of those where help was offered, was the situation improved. The complex problem of gender violence needs to be remembered while providing healthcare because it is common. Women need to be aware of their rights and possible help. We need to progress towards a civilised society with gender equality and no violence.

Averting maternal deaths in spite of resource constraints: an Indian rural experience over two decades

The present study was conducted to analyse the changing trends in maternal deaths and the factors affecting them in a rural institution in India. Analysis of case records of maternal deaths over a period of 20 years, between April 1982 and March 2002 was performed in relation to the age, parity and disorders leading to death. It was revealed that the maternal mortality ratio has declined significantly, from 890.7 between April 1982 and March 1987 to 259.4 between April 1997 and March 2002. Most of the deaths were in young women (20-29 years) and primigravidae. Hypertensive disorders (27.4%) and haemorrhage (12.9%) were the leading direct causes, while anaemia (13.9%) was the main indirect cause. It was shown that from 1982-1987 to 1997-2002 there was a fall in the percentage of deaths due to hypertensive disorders, from 27.5% to 14.6%, peripartum sepsis from 13.7% to 7.3% and ruptured uterus from 3.9% to nil, but there was a rise in deaths due to septic abortions from 9.8% to 14.0% and haemorrhage from 7.8% to 17.1%. Deaths within 24 hours of admission decreased from 60.8% between 1982 and 1987 to 46.3% between 1997 and 2002. It appears that even with resource constraints, maternal mortality can be reduced by improving peripheral services and individualised evidence- based appropriate interventions at referrals. However, the problems of anaemia and septic abortions need to be examined further.
