Skull-base temporal encephalocele: Hidden cause of temporal lobe epilepsy

ABSTRACT

In the present study patients with previously diagnosed MRI-negative temporal lobe epilepsy (TLE) on long-term video electroencephalography (VEEG) monitoring were re-evaluated with high resolution 3T MRI brain to look out for a skull base temporal lobe encephalocoele (TE). A total of 234 VEEGs were analyzed. TLE had been diagnosed in 104 patients based on semiology, ictal, interictal EEG data, and brain positron emission tomography (PET) studies. Of these, 99 patients had temporal lobe abnormality (78 had mesial temporal sclerosis, 8 had tumor, 3 had focal cortical dysplasia, and 10 had mixed pathology). Out of the five 1.5T MRI-negative TLE patients, two patients were diagnosed with TE on subsequent 3T MRI brain scans and one patient underwent electrocorticography-guided tailored resection for complete removal of epileptogenic tissue; with Engels class I seizure freedom at one year follow-up. We propose that TE should be carefully searched for, as a cause of refractory TLE, using high-resolution MRI sequences.

Efficacy of outpatient surveillance in post-intravesical BCG management of high-risk bladder cancer

Background:

Intravesical Bacillus Calmette–Guérin (BCG) instillation is an established form of immunotherapy for intermediate and high-risk bladder cancers. Mandatory cystoscopic surveillance is commonly performed under general anaesthesia (GA) to facilitate biopsy or other procedures. However, it is resource-intensive with unclear clinical benefit.

Methods and patients:

We performed a two-cycle audit, before and after changing post-BCG surveillance policy, from GA cystoscopy to local anaesthetic flexible cystoscopy (LAFC) on trans urethral laser ablation (TULA) lists, where patients may undergo a tumour biopsy or laser ablation. In the first cycle, we audited 53 patients undergoing 114 post-BCG rigid cystoscopies from January 2018 to December 2019. In the second cycle, there were 56 patients undergoing 99 post-BCG LAFCs on TULA lists in 2020.

Results:

In the first audit cycle cohort, the mean patient age was 72.29 ± 8.98 years and 48 were men; malignant histology was identified only on five occasions (three grade progressions). Fourteen patients required overnight admission. In the second audit cycle cohort, the mean patient age was 70.44 ± 9.17 years and 47 were men. Four had a grade progression, while another a stage progression. Out of 99 LAFCs, 47 confirmed normal bladder appearance. A biopsy was taken during other 52 cystoscopies: 17 (33%) confirmed malignancy. Fifteen patients showed findings that were labelled as recurrence, but only two required a further GA procedure to deal with recurrence. One patient was admitted for post-procedure bleeding, which settled with irrigation.

Conclusion:

Local anaesthetic TULA procedure is a safe and effective alternative for a GA rigid cystoscopy to survey bladders of patients on intravesical BCG therapy.

Sporotrichoid lymphocutaneous pattern in a fish-merchant under immunosuppressant medications: Clues to differential diagnoses

Sporotrichoid-lymphocutaneous-pattern is classically seen in sporotrichosis, though also present in other infections like atypical mycobacteriosis and leishmaniasis. Cutaneous atypical mycobacterial infection presents as localized lesions in immunocompetent and is widespread in immunosuppressed patients. Here, we present a case of sporotrichoid-lymphocutaneous infection due to atypical mycobacteria, in a fish-seller under immunosuppressants.

Treatment of Infrabony Defects by Open Flap Debridement with or without Diode Laser

Background Periodontitis is the common oral condition which affects the periodontium of the teeth that leads to destruction of periodontal ligaments and alveolar bone. Open flap debridement is the surgical procedure which provides access and visibility of the site, application of laser as an adjunct has various advantanges. Objective To compare clinical outcomes after open flap debridement with or without diode laser. Method Patients aged 25-45 years diagnosed with infrabony defect ≥ 5 mm visiting Department of Dental Surgery, Bir Hospital. Control group sites were treated with open flap debridement alone, whereas test-groups were treated with Open flap debridement with diode laser. Various parameters like Plaque index, Gingival index, Pocket depth and Clinical attachment level were assessed and compared between groups at baseline, 3 and 6 months. Result The mean plaque and gingival scores improved in both the control and test groups at 3 and 6 months follow up as compared to baseline and was statistically nonsignificant between two groups. Open flap debridement with or without diode laser in the treatment of periodontal intrabony defects did not produce significant reduction in pocket depth and gain in clinical attachment level. Conclusion There was no significant differences in the clinical parameters were seen in the surgical flap debridement of infrabony pocket with and without diode laser. Diode laser can be used safely as an adjunct. However, long-term, multicentric, histologic and microbial studies are required.

Assessment of Vitamin D Level in Patients with Psoriasis and Its Correlation with Disease Severity: A Case–Control Study

Background

Chronic plaque psoriasis is a chronic inflammatory skin disorder. Vitamin D has been shown to have effects on keratinocyte differentiation as well as immune regulation in the skin.

Objective

The main objective of this study was to assess the 25hydroxyvitamin D [25 (OH) D] level in patients with psoriasis in comparison with healthy control subjects.

Materials and Methods

This case–control study included 180 persons (120 cases and 60 age- and sex-matched control subjects) from outpatient department of BPKIHS, a tertiary care hospital in eastern Nepal. Severity of psoriatic skin lesions was assessed using psoriasis area severity index (PASI) scoring. Serum vitamin D level was assessed by chemiluminescent immunoassay.

Results

The mean serum 25(OH) D levels in psoriatic patients and controls were 19.57 ± 6.85 ng/mL and 23.63 ± 6.40 ng/mL, respectively. The difference was statistically significant even after adjusting for confounding factors in a multivariate analysis (aOR 2.929, 95% CI 1.376–6.230). Low serum 25(OH) D levels were negatively associated with the severity of disease (r= −0.628, P= 0.01).

Conclusion

Serum 25(OH) D levels are significantly lower in psoriatic patients than in healthy control subjects. Deficiency of serum 25(OH) D was associated with severity of disease with an inverse relationship with PASI score.

Hirsutism and Quality of Life of Women in Tertiary Care Center in Eastern Nepal

Background Hirsutism is excess terminal hair growth in women at androgen-dependent sites of the body and it has great impact on psychological and social aspects of their lives, thus affecting their quality of life (QoL). Several studies assessing the quality of life in hirsute women could be found in world literature but none in Nepalese literature. So, this study was undertaken for the assessment of the impact of hirsutism on the quality of life in Nepalese women. Objective To assess the effect of hirsutism on quality of life of women in a tertiary center of Eastern Nepal and its association with various socio-demographic and clinical parameters. Method A cross-sectional questionnaire-based study was conducted in 49 participants aged 10 to 49 years at the Department of Dermatology, B.P. Koirala Institute of Health Sciences. Clinically diagnosed hirsute females with modified Ferriman-Gallwey (mFG) score > 8, were enrolled and asked to fill Dermatology Life Quality Index (DLQI) questionnaire in the Nepalese version. Result More than 57.2% of the study population was of age 20 to 29 years with a mean of 27.76±8.08 years. The mean Dermatology Life Quality Index score was 7.78±4.95. The moderate effect was seen in the majority of participants (36.7%) with a predominant effect upon aspects of life like daily activities and symptoms and feelings. Participants with higher mF-G score (22.15±3.82) had a very large effect on their quality of life. Younger unmarried women with a school education and having a longer duration of hirsutism were found to have a higher effect upon their quality of life. However, the association was not statistically significant. Conclusion Hirsutism had affected the quality of life moderately with predominant effect upon aspects like daily activities and symptoms and feelings. No significant association was elicited between severity of hirsutism and its effect on quality of life from our study.

Urban modelling and forecasting of landuse using SLEUTH model

The present study performs landcover modelling using the SLEUTH model. The urban land use changing factors are calibrated to predict the Land Use Land Cover (LULC) for a densely populated and developing smart city, Prayagraj, India. This research aims to use the SLEUTH model for simulating the future urban growth with the help of historical LULC (1990-2020), road network and elevation data. The influence of road gravity and slope resistant coefficients is very significant in this study's outcome. The built-up area of the region increased from 40.22 km² (5.10% of total area) in 1990 to 85.89 km² (10.89%) in 2020. According to prediction results, in the next 20 years, the built-up growth rate would be 1.9% and approximated built-up area would be 118.66 km² (14.98%) in the year 2040. The quality of the result has been quantified in terms of best fit value of Optimal SLEUTH Metric (OSM) and validated against the existing LULC. The study utilises a spatially explicit urban growth model with 30 m resolution remote sensing data and provides future landuse of Prayagraj city.

Correlation of fetal ventricular size and need for postnatal cerebrospinal fluid diversion surgery in open spina bifida

OBJECTIVES

Open spina bifida is a common cause of hydrocephalus in the postnatal period. In-utero closure of the fetal spinal defect decreases the need for postnatal cerebrospinal fluid (CSF) diversion surgery. Good prenatal predictors of the need for postnatal CSF diversion surgery are currently lacking. In this study, we aimed to assess the association of fetal ventriculomegaly and its progression over the course of pregnancy with the rate of postnatal hydrocephalus requiring intervention.

METHODS

In this retrospective study, fetuses with a prenatal diagnosis of open spina bifida were assessed longitudinally. Ventricular diameter, as well as other potential predictors of the need for postnatal CSF diversion surgery, were compared between fetuses undergoing prenatal closure and those undergoing postnatal repair.

RESULTS

The diameter of the lateral ventricle increased significantly throughout gestation in both groups, but there was no difference in maximum ventricular diameter at first or last assessment between fetuses undergoing prenatal closure and those undergoing postnatal repair. There was no significant difference in the rate of progression of ventriculomegaly between the two groups, with a mean progression rate of 0.83 ± 0.5 mm/week in the prenatal-repair group and 0.6 ± 0.6 mm/week in the postnatal-repair group (P = 0.098). Fetal repair of open spina bifida was associated with a lower rate of postnatal CSF diversion surgery (P < 0.001). In all subjects, regardless of whether they had prenatal or postnatal surgery, the severity of ventriculomegaly at first and last assessments was associated independently with the need for postnatal CSF diversion surgery (P = 0.005 and P = 0.001, respectively), with a greater need for surgery in fetuses with larger ventricular size, even after controlling for gestational age at assessment.

CONCLUSIONS

In fetuses with open spina bifida, fetal ventricular size increases regardless of whether spina bifida closure is performed prenatally or postnatally, but the need for CSF diversion surgery is significantly lower in those undergoing prenatal repair. Ventriculomegaly is associated independently with the need for postnatal CSF diversion in fetuses with open spina bifida, irrespective of timing of closure. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

COVID-19 pandemic lockdown - Is it affecting our skin hygiene and cosmetic practice?

Background

Orders such as self‐isolation, quarantine, social distancing, and lockdown implemented as a protective measure against COVID‐19 has allowed people to devote their excess leisure time to their appearance, cosmetics, and hygiene.

Objective

To assess the skin care routine regarding hygiene and cosmetic practices among female users of social media during the COVID‐19 pandemic.

Method

A cross‐sectional study was done among 300 female social media users using purposive sampling. A self‐administered questionnaire that included questions related to hygiene practices such as hand washing, use of hand sanitizers, bathing, hair washing, and use of certain cosmetics before and during the pandemic was used to collect all relevant data.

Result

Handwashing after returning home and shaking hands with others increased during the pandemic as compared with prior practices. The frequency of using a hand sanitizer had also increased during the pandemic. There was a statistically significant decrease in the frequency of the hair removal and visits to beauty salons during the pandemic. Cosmetics were used less, although face creams and lip balm were used more. Even though most of our respondents thought pandemic practices were convenient to use, more than half of them said they wished to go back to their pre‐pandemic routines once the pandemic was over.

Conclusion

The study revealed an increase in washing behavior, use of facial cream, and lip balms. Moreover, a decrease in using make‐up cosmetics, hair removal, and beauty salon visits during the pandemic.

Predicting Quadruple Semitendinosus Graft Size for Anterior Cruciate Ligament Reconstruction by Patient Anthropometric Variables: A Cohort Study of 280 Cases

Introduction:

Pre-operative identification of patients with inadequate hamstring graft for anterior cruciate ligament reconstruction is still a subject of interest. The purpose of this study is to correlate dimension of a harvested dimensions graft with patient physical anthropometric variables.

Materials and methods:

This cohort study included 280 patients (male = 226, female = 54) scheduled for primary anterior cruciate ligament (ACL) reconstruction. Interrelationships between quadruple semitendinosus (ST) graft and anthropometric parameters (age, sex, height, weight, and BMI) were assessed using Pearson Correlation test and regression analysis. Difference among gender was analysed using Mann Whitney and t test. The observed graft diameter was also compared with the literature using Bland – Altman plot.

Results:

Mean age of cohort was 29 years (range, 17-50 years), mean height was 1.69m (range, 1.6-1.9m), mean weight was 75 kg (range, 50-116kg) and mean BMI was 26kg/m2 (range 16.65-40.40kg/m2). Mean quadruple length of harvested ST graft was 7cm (7.1±0.6 cm, range, 5.6-8.8cm) and mean diameter was 8mm (8.2±0.8mm, range, 6.5-10mm). Only height and weight were significantly correlated with graft length and diameter in both sex (p value <0.05). Female, compared to male, had significantly smaller (p<0.0001) and thinner graft (p<0.0001). There was a strong agreement between the literature and our observed graft diameter, but with an overestimated graft diameter in 18.5% of the cases.

Conclusion:

Among anthropometric parameter, only height and weight had moderate positive correlation with graft diameter. Males had longer and wider ST graft in contrast to age-matched female group.

Awareness, acceptability, and satisfaction of teledermatology consultation among social-media users in Nepal

BACKGROUND

Teledermatology refers to the use of telecommunication in consulting one's skin problem to a dermatologist at distance.

AIMS

This study aims to identify the awareness, acceptability, preferred technical tools, willingness to use, comfortability, and satisfaction of teledermatology among social-media users in Nepal.

METHODS

It was an exploratory cross-sectional study performed on 360 social-media users, subjected to web-based interview based on pretested proforma containing questions to address: awareness of telemedicine, type and tools preferred for teledermatology, willingness to use, comfortability, and satisfaction of teledermatology services.

RESULTS

Most of the participants (60.8%) were initially unaware of telemedicine. Despite this, the majority (81.9%) were willing to use the services after being aware, mostly during the follow-up (36.6%). Most of the participants (61.1%) preferred the hybrid model for teleconsultation, while mobile was the preferred technical tool (68.1%) mostly because of its compatibility (84.1%) and portability (56.3%). The majority of the participants felt that teledermatology consultation would be beneficial (77.2%) and they mostly preferred it directly from a dermatologist (85.6%). About two-thirds (64.2%) also believed that teledermatology consultation would eliminate the need for a face-to-face consultation. The majority would be comfortable (68.1%) if their skin lesions are photographed and sent to a dermatologist and would be satisfied (62.5%) with the consultations, through Wi-Fi and mobile data both (55.6%), and via Facebook (97.2%) and Viber (70.8%).

CONCLUSIONS

Despite being unaware of telemedicine, the participants were willing to use teledermatology consultation and thought that they would be comfortable and satisfied with it.

Intralesional Bleomycin for the Treatment of Resistant Palmoplantar and Periungual Warts

INTRODUCTION

Periungual, palmar, and plantar warts are difficult to treat with poor treatment response. Intralesional (IL) bleomycin has shown promising results for their treatment in a few reports. However, we need further evidence before opting it for treating difficult sites and resistant warts. Hence, we conducted this study to assess the efficacy and safety of IL bleomycin for the treatment of resistant palmoplantar and periungual warts.

METHODS

In this retrospective study, we included all patients who were given IL bleomycin for warts over a year. Maximum three sittings of bleomycin (1 mg/ml) were given monthly, and they were followed up for 3 months after the procedure. The response was categorized as complete, near-complete, significant, moderate, mild, and no clearance for 100%, 75-99%, 50-74%, 25-49%, 1-25%, and 0% clearance, respectively.

RESULTS

Out of 29 patients, follow-up details were available only in 19 patients (53 warts). The mean duration was 2.5 ± 1.47 years. The number of past interventions ranged from 2-4. Wart clearance after the first intervention was complete in 36.84%, near-complete in 26.31%, significant in 26.31%, and moderate in 10.53%. Wart clearance after the last intervention was complete in 89.47% and near-complete in 10.52% of patients. However, during 3 months of follow-up after the last injection, 15.78% had a recurrence. None of them had severe local and systemic side effects.

CONCLUSIONS

IL bleomycin could be a better treatment option for the treatment of resistant and difficult warts. However, we observed a higher recurrence rate even in a shorter follow-up. Hence, we need further studies with larger samples.

Impact of Social Media and Photo-Editing Practice on Seeking Cosmetic Dermatology Care

BACKGROUND

The use of social media and photo-editing practice has grown enormously over the past decades. Photo editing can alter a person's desire to look better in photographs posted on social media platforms.

OBJECTIVE

To assess the cosmetic dermatology seeking behavior of social media users and those who edit photographs before posting them on social media platforms.

METHODS

A validated self-administered structured questionnaire via Google form was sent to 550 social media users in Nepal. It included 5 sub-headings: use of social networking sites, photo-editing practices, awareness and motivation about cosmetic dermatology care, cosmetic dermatology care seeking behavior and self-esteem.

RESULTS

Facebook and Instagram were the preferred social networking sites for posting photographs. One-fourth of the participants edited >40% of the total photos posted in social media. Hiding skin lesions was the most common reason (36.3%) for photograph editing. Fifty percent of the respondents felt the need to look better; repair skin damage; be able to look good without make up; look younger; feel happier and improve total quality of life as a "lot and top" motivation for using the cosmetic dermatological procedures. A majority preferred to seek cosmetic dermatology care from non-dermatologists because they felt dermatologist visit was not needed, the services were costly and they could not visit due to their busy schedule. On multivariate analysis, respondents who were aware of skin care favored seeking cosmetic dermatology care from dermatologists.

CONCLUSION

Higher investment in social media and photo-editing practices might be associated with increased non-dermatologist seeking behavior.

P–638 Status of insulin resistance in infertile women and its effect on ovulation induction

Study question

Is insulin resistance ( IR) a confounding variable in infertile women, other than those those having polycystic ovarian syndrome (PCOS)

Summary answer

IR was identified in 20.5% of infertile women. The presence of IR did not affect response to ovulation induction but reduced chances of conception

What is known already

Obesity is strongly correlated with insulin resistance. Obesity also has an adverse effect on fertility. In 2008 Steeg et al reported 5% reduction in chances of spontaneous conception with each unit increase in body mass index (BMI). Tetsurou Sakumoto et al (2010) reported hyperinsulinemia to affect granulose cells in small follicles inducing early response to luteinising hormone and anovulation. Adverse effect on endometrial function and implantation was also postulated. Insulin resistance has been studied in cases of PCOS but has not been studied in infertile women not fulfilling criteria for diagnosis of PCOS . So the present study was planned

Study design, size, duration

A prospective cohort study was conducted in infertility unit, King George Medical University, Lucknow, India over a period of one year from August 2018 to July 2019. Total 102 women with unexplained infertility were enrolled. Ethical clearance was obtained from institutional ethical committee

Participants/materials, setting, methods

Women with PCOS; diminished ovarian reserve documented by antral follicle count &lt;7 and anti Mullerian hormone &lt; 1.1ng/ml; bilateral tubal block; abnormal semen analysis; untreated hypothyroidism, hyperprolactinaemia; known diabetes were excluded. All women underwent ovulation induction with clomiphene citrate followed by single intrauterine insemination. Homeostasis model assessment insulin resistance index (HOMA IR) was calculated

HOMA-IR = Fasting S. Glucose (mg/dl) x Fasting insulin (µlU) / 405.

Value ≥ 2 denoted insulin resistance

Main results and the role of chance

: IR was identified in 21/102 (20.5%) cases. Fasting insulin levels were in the range of 5 – 9.9 mIU/ml in 53/102 women; &lt;5mIU/ml in 29 and &gt;10mIU/ml in 20. Fasting insulin &gt; 9.45mIU/ml was found to have 90.5% sensitivity and 96.3% specificity in predicting insulin resistance. None of the cases had abnormal fasting and post prandial plasma glucose levels. IR was seen to be significantly correlated with BMI &gt; 25kg/m2 (p = 0.0018) and waist hip ratio of &gt; 0.85 (p = 0.0024).All women had follicular development and follicle rupture irrespective of presence of IR. Women with IR were more likely to have monofollicular development (17/21 IR cases). Correlation of endometrial thickness with IR was not seen. Mean endometrial thickness was 8.9mm. There were 6 pregnancies among the 102 women studied. None of the women with IR conceived.

So IR was found to be affecting one fifth of women with unexplained infertility. Failure of any woman with IR to conceive was significant but the finding needs to be further studied.

Limitations, reasons for caution

: It was a small study with only 102 cases and the women were followed for only one cycle of ovulation induction and intrauterine insemination so results need to be validated in a larger study with a longer follow up.

Wider implications of the findings: If further larger studies corroborate the role of IR in women with unexplained infertility it could elucidate the possibility of using insulin sensitisers in management of such cases. IR may emerge as an important gamechanger in management of unexplained infertility.

Family vitiligo impact scale: A scale to measure the quality-of-life of family members of patients with vitiligo

BACKGROUND

Vitiligo places a significant psycho-social burden on caregivers and family members.

AIMS

The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members.

METHODS

Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question.

RESULTS

A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach's alpha coefficient of 0.92 (0.70-0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity.

LIMITATIONS

It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive.

CONCLUSION

Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settings.

Co-occurrence of progressive hemifacial atrophy due to morphea with homolateral segmental vitiligo: A case report

Prevalence and risk factors of striae gravidarum in a cohort of multiracial postpartum Nepalese population

BACKGROUND

Striae gravidarum (SG), popularly called as stretch marks, is a common pregnancy-related asymptomatic skin condition, but is a cosmetic concern for females. A few epidemiological studies have been reported from Asian countries. However, no such study has been done in Nepal.

AIMS

This study was aimed to know the prevalence and risk factors associated with SG in a cohort of multi-ethnic postpartum Nepalese women who had delivered after completion of 36 weeks.

PATIENTS/METHOD

A cross-sectional comparative study was conducted among 420 postpartum females who had delivered after completion of 36 weeks of gestation. Data were collected in the form of a questionnaire and relevant physical examination was done. The severity of SG was assessed by using Davey's scoring.

RESULT

Out of 420 females, 260 (62%) had SG while 160 (38%) did not. According to the results of logistic regression analysis, young age (<25 years), large abdominal circumference (>100 cm), increased weight gain during pregnancy (>15 kg), presence of family history of SG, gestational diabetes mellitus, altered bowel movement, and presence of striae on the breasts, thighs, and buttocks were found to be independent risk factors for SG.

CONCLUSIONS

Future expectant mothers must be informed about the risk factors of SG development. They need to be made aware that SG can be prevented by considering the modifiable risk factors, such as excessive weight gain. They should also be informed that SG is permanent and currently there is no definite treatment.

Dyschromatosis Universalis Hereditaria

Dyschromatosis universalis hereditaria (DUH) is a rare pigmentary genodermatosis usually inherited in autosomal dominant fashion characterized by multiple pinpoint to pea-sized hypo- and hyper-pigmented macules arranged in reticulate pattern that develops within the first few years of life. An 11 years old boy presented with multiple gradually progressive asymptomatic hypopigmented macules on hyperpigmented background on trunk, extremities and face since 2 years of age. Family history was absent. Punch biopsies revealed increased number of melanocytes in the epidermis with basal cell vacuolar alteration and pigmentary incontinence and perivascular infiltration by lymphocytes and melanophages in the dermis. We herein present a sporadic case of dyschromatosis universalis hereditaria.

Difficulties in developmental follow-up of preterm neonates in a randomised-controlled trial of Bifidobacterium breve M16-V - Experience from Western Australia

BACKGROUND

Probiotics may be neuroprotective for preterm neonates due to their anti-inflammatory effects and ability to facilitate nutrition.

AIM

To assess long-term effects of early probiotic supplementation on neuropsychological development in preterm infants.

STUDY DESIGN

Follow up study.

SUBJECTS

Children at age 3 to 5 years who had participated as preterm infants (<33 week) in the randomised controlled trial.

OUTCOMES

Primary: Continuous early learning composite measure derived from the Mullen's Scale of Early Learning (MSEL). Other outcomes were assessed by the Developmental, Dimensional and Diagnostic Interview, Developmental NEuroPSYchological assessment-2nd Edition, Parental questionnaires using children's communication checklist-2nd edition, social responsiveness scale, and Vineland Adaptive Behavioural Scales-2nd edition.

MEASURES

Continuous scores derived from all the measures.

RESULTS

67 children of the 159 participants (42%) (Probiotic: 36/79, Placebo: 31/80) were followed-up for at least one neuropsychological assessment. All six assessments were completed in 18/31 (58.1%) of the control vs. 11/36 (30.6%) probiotic group children. Multivariable analysis of MSEL composite score showed no evidence of probiotic effect univariately, or after adjustment for gestation, intrauterine growth restriction, Apgar <7 at 5 min and age at assessment (adjusted mean effect in probiotic group: -2.7, 95% CI -8.5-3.0, p = 0.349).

CONCLUSION

There was no significant effect on neurodevelopment of children assessed at the age of 3 to 5 years who participated as preterm neonates in the RCT of B. breve M-16V. The validity of these results is limited by the reduced sample size due to high rate of loss to follow up.

Long-term postnatal outcome of fetuses with prenatally suspected septo-optic dysplasia

OBJECTIVES

Septo-optic dysplasia (SOD) is a clinical syndrome characterized by varying combinations of optic nerve hypoplasia, pituitary gland hypoplasia and abnormal cavum septi pellucidi. It is suspected on prenatal imaging when there is non-visualization or hypoplasia of the septal leaflets. Long-term postnatal outcomes of fetuses with prenatally suspected SOD have been documented poorly. The aims of this study were to describe the natural history of deficient septal leaflets, to quantify the incidence of postnatally confirmed SOD and to document the visual, endocrine and long-term neurodevelopmental outcomes of these infants.

METHODS

This was an observational retrospective study of all fetuses with prenatal imaging showing isolated septal agenesis, assessed at a single tertiary center over an 11-year period. Pregnancy, delivery and neonatal outcomes and pre- and postnatal imaging findings were reviewed. Neonatal evaluations or fetal autopsy reports were assessed for confirmation of SOD. Ophthalmologic, endocrine, genetic and long-term developmental evaluations were assessed. Imaging findings and outcome were compared between infants with and those without postnatally confirmed SOD.

RESULTS

Of 214 fetuses presenting with septal absence on prenatal ultrasound and magnetic resonance imaging (MRI), 18 (8.4%) were classified as having suspected isolated septal agenesis suspicious for SOD. Uniform prenatal MRI findings in cases with suspected SOD included remnants of the leaflets of the cavum septi pellucidi, fused forniceal columns, normal olfactory bulbs and tracts and a normal optic chiasm. Twelve fetuses were liveborn and five (27.8%) had postnatally confirmed SOD. Only two of these five fetuses had additional prenatal imaging features (pituitary cyst, microphthalmia and optic nerve hypoplasia) supporting a diagnosis of SOD. The other three confirmed SOD cases had no predictive prenatal or postnatal imaging findings that reliably differentiated them from cases without confirmed SOD. Visual and endocrine impairments were present in two (40%) and four (80%) cases with confirmed SOD, respectively. In those with visual and/or endocrine impairment, developmental delay (median age at follow-up, 2.5 (interquartile range, 2.5-7.0) years) was common (80%) and mostly severe. Neonates with isolated septal agenesis and a lack of visual or endocrine abnormalities to confirm SOD had normal development.

CONCLUSIONS

Only a quarter of fetuses with isolated septal agenesis suggestive of SOD will have postnatal confirmation of the diagnosis. Clinical manifestations of SOD are variable, but neurodevelopmental delay may be more prevalent than thought formerly. © 2020 Authors.

From the Knife to the Endoscope-a History of Bariatric Surgery

PURPOSE OF REVIEW

Current bariatric surgical practice has developed from early procedures, some of which are no longer routinely performed. This review highlights how surgical practice in this area has developed over time.

RECENT FINDINGS

This review outlines early procedures including jejuno-colic and jejuno-ileal bypass, initial experience with gastric bypass, vertical banded gastroplasty and biliopancreatic diversion with or without duodenal switch. The role laparoscopy has played in the widespread utilization of surgery for treatment of obesity will be described, as will the development of procedures which form the mainstay of current bariatric surgical practice including gastric bypass, sleeve gastrectomy and adjustable gastric banding. Endoscopic therapies for the treatment of obesity will be described. By outlining how bariatric surgical practice has developed over time, this review will help practicing surgeons understand how individual procedures have evolved and also provide insight into potential future developments in this field.

FRI0033 ANTI-CARBAMYLATED PROTEIN POSITIVITY PREDICTS DAS28-REMISSION AT 12 MONTHS IN PATIENTS WITH EARLY RHEUMATOID ARTHRITIS: RESULTS FROM THE SINGAPORE EARLY ARTHRITIS COHORT

Background:

Anti-carbamylated protein antibody (anti-carp) positivity has been associated with poorer outcomes in Western cohorts of early rheumatoid arthritis; however, it is unknown if this applies to Asians.

Objectives:

We determined whether anti-carp predicted DAS28-remission, disability and radiographic progression in a multi-ethnic Asian ERA cohort.

Methods:

Patients with physician diagnosed ERA (symptom duration ≤1 year) were recruited from the Singapore Early Arthritis Cohort (n= 317) by convenience sampling. Serum anti-carp was measured cross-sectionally using a commercial ELISA (SincereBio). The test was repeated in 40 healthy individuals to establish the optimal sensitivity and specificity for the diagnosis of RA via a receiver operating curve. Disease activity (DAS28-ESR or DAS28-CRP) was recorded at baseline, 3, 6 and 12 months. Two independent accessors quantified the radiographic damage at baseline and at follow-up using the modified Sharp van der Heijde score (mSS). We used multivariable logistic regression to determine whether anti-carp predicted the following outcomes; (i) DAS-28 remission at 12 months, (ii) any disability (mHAQ>0) at 12 months and (iii) radiographic progression (any increase in the mSS). In each regression model, we chose covariates known to influence the dependent variable in our cohort or from literature.

Results:

One hundred patients were recruited, of mean age (SD) 49.8 (12.5) years, median (IQR) disease duration 10.2 (6.9-15.1) weeks at cohort entry and baseline median DAS-28 4.5 (2.9-5.9) (Table 1). The anti-carp assay was performed after a median (IQR) disease duration of 2.24 (1.82-3.14) years. 93 patients had baseline hand radiographs and 66 had follow-up hand radiographs after ≥ 12 months. Receiver operating characteristics curve yielded optimal sensitivity (95%) and specificity (60%) for the diagnosis of RA at 1.60OD. Therefore, 60 patients were anti-carp positive and 35 patients (37.2%) were positive for RF, ACPA and anti-carp (Figure 1). Anti-carp positivity independently predicted DAS28-remission at 12 months (OR 3.41, 95% CI 1.08-10.7,p=0.04) (Table 2). Anti-carp positivity did not predict disability at 12 months (OR 0.61, 95% CI 0.18-2.07,p=0.43) or radiographic progression (OR 0.23, 95% CI 0.03-2.03,p=0.18).

Conclusion:

Contrary to previous studies done on Western cohorts where anti-carp predicted worse outcomes, anti-carp positivity predicted DAS28-remission at 12 months in our multi-ethnic Asian cohort. This suggests that different genetic and environmental determinants account for anti-carp expression in patients with RA.

0707 “What We’Ve Got Here Is Failure To Communicate”: Apnea Patients And Their DME Suppliers

Introduction

Successful treatment of obstructive sleep apnea requires adherence to positive airway pressure (PAP) therapy. A key factor is the relationship between the DME provider and the patient so that treatment can be initiated and continued in a timely manner. Our quality improvement project aims to empower and enable patients towards active participation in their sleep apnea care. Our goal is to ultimately increase patients’ knowledge of their Durable Medical Equipment (DME) supplies company, and thus improve their treatment. The first step was to determine patients’ familiarity with their DME.

Methods

Forty-one patients with sleep apnea on PAP therapy volunteered to be questioned about their DME company during clinic visits at the Yale North Haven Sleep Center, Connecticut, starting November 2019. Patients were asked if they knew the name or the contact of their DME; whether they received adequate training on PAP therapy initiation; if they were receiving timely and correct PAP therapy supplies. They were asked to rate their satisfaction with the DME on a scale of 1 to 5; one being very dissatisfied and five being very satisfied.

Results

Only 12 out of 41 patients (29.3 percent) knew the names of their DME companies. The average satisfaction rating was 3 (neutral); 44% of patients were dissatisfied, or very dissatisfied with the performance of their DME. Detailed comments were mostly related to poor contact and communication with the DME.

Conclusion

Most apnea patients had difficulty identifying and contacting their DME. As the next step of this quality improvement project we plan to intervene to ensure that the patients have the name and contact information of their DME available and attached to their PAP machine equipment. We plan to repeat this questionnaire after this intervention to study the impact of this quality improvement project.

High-resolution imaging of the human incudostapedial joint using synchrotron-radiation phase-contrast imaging

The incudostapedial joint (ISJ) of the middle ear is important for proper transmission of sound energy to the cochlea. Recently, the biomechanics of the ISJ have been investigated using finite-element (FE) modelling, using simplified geometry. The objective of the present study was to investigate the feasibility of synchrotron-radiation phase-contrast imaging (SR-PCI) in visualising the ISJ ultrastructure. Three human cadaveric ISJs were dissected and scanned using SR-PCI at 0.9 µm isotropic voxel size. One of the samples was previously scanned at 9 µm voxel size. The images were visually compared and contrast-to-noise ratios (CNRs) were calculated (of both bone and soft tissues) for quantitative comparisons. The ISJ ultrastructure as well as adjacent bone and soft tissues were clearly visible in images with a 0.9 µm voxel size. The CNRs of the 0.9 µm images were relatively lower than those of the 9 µm scans, while the ratio of bone to soft tissue CNRs were higher, indicating better discernibility of bone from soft tissue in the 0.9 µm scans. This study was the first known attempt to image the ISJ ultrastructure using an SR-PCI scanner at submicron voxel size and results suggest that this method was successful. Future studies are needed to optimise the contrast and test the feasibility of imaging the ISJ in situ. LAY DESCRIPTION: The human middle ear consists of the eardrum, three small bones (the malleus, incus and stapes) and two joints connecting the bones (the incudostapedial joint and the incudomallear joint). The role of the middle ear is to amplify and transfer sound energy to the cochlea, the end organ of hearing. The incudostapedial joint (ISJ) of the middle ear is a synovial joint which is important for proper transmission of sound energy to the cochlea. Similar to other synovial joints it consists of meniscus, fluid and articulating surfaces. Recently, the biomechanics of the ISJ have been investigated using computational models, using grossly simplified geometry. Synchrotron radiation phase contrast imaging (SR-PCI) is a high-resolution imaging technique used to visualise small structures in three dimensions. The objective of the present study was to investigate the feasibility of using SR-PCI in visualising the ISJ ultrastructure. Three human cadaveric ISJs were dissected and scanned using SR-PCI at 0.9 µm isotropic voxel size. One of the samples was previously scanned at 9 µm voxel size. The images were both qualitatively and quantitatively compared. This study was the first known attempt to image the ISJ ultrastructure using an SR-PCI scanner at submicron voxel size and results suggest that this method was successful. Future studies are needed to optimise the contrast and feasibility of imaging the ISJ in situ.

Symphytum officinale augments osteogenesis in human bone marrow-derived mesenchymal stem cells in vitro as they differentiate into osteoblasts

ETHNOPHARMACOLOGICAL RELEVANCE

Mesenchymal stem cells (MSCs) are multipotent stem cells possessing regenerative potential. Symphytum officinale (SO) is a medicinal plant and in homoeopathic literature, believed to accelerate bone healing.

AIM OF THE STUDY

This study aimed to determine if homoeopathic doses of SO could augment osteogenesis in MSCs as they differentiate into osteoblasts in vitro.

MATERIALS AND METHODS

Bone marrow samples were obtained from patients who underwent bone grafting procedures (n = 15). MSCs were isolated, expanded and characterized by flow cytometry (CD90, CD105). Cytotoxicity of SO was evaluated by MTT assay. Osteogenic differentiation was induced in MSCs with β-glycerophosphate, ascorbic acid and dexamethasone over 2 weeks. Different homoeopathic doses of SO (MT, 3C, 6C, 12C and 30C) were added to the basic differentiation medium (BDM) and efficiency of MSCs differentiating into osteoblasts were measured by evaluating expression of Osteocalcin using flow cytometry, and alkaline phosphatase activity using ELISA. Gene expression analyses for osteoblast markers (Runx-2, Osteopontin and Osteocalcin) were evaluated in differentiated osteoblasts using qPCR.

RESULTS

Flow cytometry (CD90, CD105) detected MSCs isolated from bone marrow (93-98%). MTT assay showed that the selected doses of SO did not induce any cytotoxicity in MSCs (24 hours). The efficiency of osteogenic differentiation (2 weeks) for different doses of Symphytum officinale was determined by flow cytometry (n = 10) for osteoblast marker, Osteocalcin, and most doses of Symphytum officinale enhanced osteogenesis. Interestingly, gene expression analysis for Runx-2 (n = 10), Osteopontin (n = 10), Osteocalcin (n = 10) and alkaline phosphatase activity (n = 8) also showed increased osteogenesis with the addition of Symphytum officinale to BDM, specially mother tincture.

CONCLUSIONS

Our findings suggest that homoeopathic dose (specially mother tincture) of Symphytum officinale has the potential to enhance osteogenesis.

Benefits of barbed suture utilisation in gastrointestinal anastomosis: a systematic review and meta-analysis

INTRODUCTION

Anastomosis formation constitutes a critical aspect of many gastrointestinal procedures. Barbed suture materials have been adopted by some surgeons to assist in this task. This systematic review and meta-analysis compares the safety and efficacy of barbed suture material for anastomosis formation compared with standard suture materials.

METHODS

An electronic search of Embase, Medline, Web of Science and Cochrane databases was performed. Weighted mean differences were calculated for effect size of barbed suture material compared with standard material on continuous variables and pooled odds ratios were calculated for discrete variables.

FINDINGS

There were nine studies included. Barbed suture material was associated with a significant reduction in overall operative time (WMD: -12.87 (95% CI = -20.16 to -5.58) (P = 0.0005)) and anastomosis time (WMD: -4.28 (95% CI = -6.80 to -1.75) (P = 0.0009)). There was no difference in rates of anastomotic leak (POR: 1.24 (95% CI = 0.89 to 1.71) (P = 0.19)), anastomotic bleeding (POR: 0.80 (95% CI = 0.29 to 2.16) (P = 0.41)), or anastomotic stricture (POR: 0.72 (95% CI = 0.21 to 2.41) (P = 0.59)).

CONCLUSIONS

Use of barbed sutures for gastrointestinal anastomosis appears to be associated with shorter overall operative times. There was no difference in rates of complications (including anastomotic leak, bleeding or stricture) compared with standard suture materials.
