Prevalence, correlates and common methods of non-suicidal self-injury in South Asia: a systematic review

INTRODUCTION

The dynamics of self-harm vary substantially around the world, yet it is severely under-researched outside of a small number of high-income 'Western' countries. South Asia is disproportionately impacted by suicide, yet we know less about non-suicidal self-injury (NSSI) in the region.

OBJECTIVE

To review and summarise evidence on the prevalence, correlates and common methods of NSSI in South Asia.

METHODS

We searched Medline, Embase and PsycINFO for the period 1 January 2000 to 31 August 2023, for peer-reviewed observational studies. A total of 11 studies from eight South Asian countries that reported prevalence and/or correlates of NSSI were included in this review. We assessed the quality of the studies using the Study Quality Assessment Tools for Observational Cohort and Cross-Sectional Studies. We used meta-regression to describe the sources of heterogeneity. Abstracted data were summarised using thematic synthesis.

RESULTS

For non-clinical populations, the 12-month prevalence of NSSI ranged from 3.2% to 44.8%, and the lifetime prevalence ranged from 21% to 33%. For clinical populations, the 12-month prevalence of NSSI ranged from 5% to 16.4%, while the lifetime prevalence ranged from 2% to 27%. Male sex, unemployment, financial stress, history of suicidal behaviour and depression were associated with a higher risk of NSSI. Better access to counselling services, higher self-esteem and self-knowledge were associated with a lower risk of NSSI.

CONCLUSION

The burden of NSSI in South Asia appears to be high in both clinical and non-clinical populations. Further research, especially with general population samples, is needed to build evidence on the epidemiology, context and meaning of NSSI in South Asia to inform the design of context-specific interventions.

Thyroglossal Duct Cyst Carcinoma: Lessons from a 20-Case Series

Aims and Objectives

Thyroglossal duct cyst (TDC) is a common congenital cyst with an incidence of about 7%. Thyroglossal duct cyst carcinoma (TDCC) is a rare sequel which arises from TDC and has an incidence of about 1%. As these are rare, they do not have well-defined management guidelines. The aim of this study was to analyse the clinical profile and pathological characteristics of patients with thyroglossal duct cyst carcinoma and to propose a protocol for their treatment and follow-up.

Materials and Methods

A retrospective study was done from January 2000 to December 2019. All the clinical details, imaging characteristics, treatment and histopathology were analysed.

Results

The mean age group in our study was 37.9 years with a female preponderance. The clinical features like rapid increase in size, fixity of the lump and lymph node metastasis were not very common. Seventy-five percent of our patients who underwent imaging had suspicious characteristics. Fifty-six percent of our patients had FNAC suggestive of TDCC. Fifty percent of our patients had concomitant thyroid carcinoma. None of our patients had distant metastasis at follow-up.

Conclusions

TDCC is rare and a disease of young adulthood and usually has good prognosis. It may be a clinical surprise or a small lesion which can be detected with ultrasound and targeted FNAC. There is high rate of concomitant thyroid carcinoma and hence needs careful assessment. Sistrunk's procedure with total thyroidectomy either staged or simultaneously has good outcome and permits adjuvant treatment.

Training for mental health professionals in responding to experienced and anticipated mental health-related discrimination (READ-MH): protocol for an international multisite feasibility study

BACKGROUND

Mental health and other health professionals working in mental health care may contribute to the experiences of stigma and discrimination among mental health service users but can also help reduce the impact of stigma on service users. However, few studies of interventions to equip such professionals to be anti-stigma agents took place in high-income countries. This study assesses the feasibility, potential effectiveness and costs of Responding to Experienced and Anticipated Discrimination training for health professionals working in mental health care (READ-MH) across low- and middle-income countries (LMICs).

METHODS

This is an uncontrolled pre-post mixed methods feasibility study of READ-MH training at seven sites across five LMICs (China, Ethiopia, India, Nepal and Tunisia).

OUTCOME MEASURES

knowledge based on course content, attitudes to working to address the impact of stigma on service users and skills in responding constructively to service users' reports of discrimination. The training draws upon the evidence bases for stigma reduction, health advocacy and medical education and is tailored to sites through situational analyses. Its content, delivery methods and intensity were agreed upon through a consensus exercise with site research teams. READ-MH will be delivered to health professionals working in mental health care immediately after baseline data collection; outcome measures will be collected post-training and 3 months post-baseline, followed by qualitative data collection analysed using a combined deductive and inductive approach. Fidelity will be rated during the delivery of READ-MH, and data on training costs will be collected. Quantitative data will be assessed using generalised linear mixed models. Qualitative data will be evaluated by thematic analysis to identify feedback about the training methods and content, including the implementability of the knowledge and skills learned. Pooled and site-specific training costs per trainee and per session will be reported.

CONCLUSIONS

The training development used a participatory and contextualised approach. Evaluation design strengths include the diversity of settings, the use of mixed methods, the use of a skills-based measure and the knowledge and attitude measures aligned to the target population and training. Limitations are the uncertain generalisability of skills performance to routine care and the impact of COVID-19 restrictions at several sites limiting qualitative data collection for situational analyses.

Media reporting of suicide in the bengaluru E-edition of three major indian dailies: An archival study

India has the world's largest newspaper market, with over 100 million copies sold daily. The media scapegoat, simplify, speculate, and sensationalize suicide-related news instead of signposting people to seek help. Suicide affects individuals, families, and communities and is worthy of responsible reporting. This study examined the quality of newspaper coverage of suicides from January to December 2017 in three popular English dailies in Bengaluru, South India. Three hundred and ninety-five online suicide reports were evaluated for compliance with the 2017 WHO recommendations for responsible suicide reporting by media professionals. The secondary data were obtained from digital newspaper archives and analyzed. A handful of the sampled articles met key recommendations. While reporting on suicide in the Indian media, three critical areas that require the most attention are reducing sensationalism, providing help-seeking information, and educating the public on suicide prevention without perpetuating myths.

Indian media professionals' perspectives regarding the role of media in suicide prevention and receptiveness to media guidelines: a qualitative study

OBJECTIVES

Crime reports of suicide incidents routinely feature in the Indian mass media, with minimal coverage of suicide as a broader public health issue. To supplement our recently published content analysis study, we undertook qualitative interviews to examine media professionals' perspectives and experiences in relation to media reporting of suicide-related news in India.

DESIGN AND SETTING

In 2017-2018, we undertook semistructured qualitative interviews with media professionals with experience reporting on suicide-related news. A semistructured interview guide was designed to initiate discussions around their perspectives and experiences in relation to reporting on suicide. Interviews were digitally audio-recorded and transcribed, and a deductive and inductive approach to thematic analysis was used.

PARTICIPANTS

Twenty-eight interviews were undertaken with media professionals in Delhi, Chandigarh and Chennai.

RESULTS

A clear role for media in suicide prevention framed around educating and informing the public was articulated by several participants and a majority of participants also reported concerns and anecdotal accounts that their reporting may negatively influence vulnerable people in the population. Nonetheless, a fatalistic attitude towards suicide was evident among several participants including dismissing or minimising concerns around imitation suicides. Several participants also expressed doubts around the quality of suicide helplines in India and were hesitant to add such contact details to their reports. Participants were largely very receptive to the idea of developing voluntary media guidelines for the Indian context, although doubts were raised around compliance unless additional initiatives were taken to engage media professionals at the highest levels.

CONCLUSIONS

Our findings reveal the perspectives of media professionals operating in the Indian context and can be used to support constructive partnerships between media professionals and suicide prevention experts. There is a clear need for a genuine and sustained partnership between suicide prevention experts and media professionals at all levels.

Does Baseline PTH Influence Recovery of Bone Mineral Density, Trabecular Bone Score and Bone Turnover Markers? A Prospective Study Following Curative PArathyroidectomy in Primary Hyperparathyroidism

OBJECTIVE

This prospective study was carried out to assess trabecular bone score, bone mineral density (BMD), and bone biochemistry in Indian subjects with symptomatic primary hyperparathyroidism (PHPT), and to study the influence of baseline parathyroid hormone (PTH) on recovery of these parameters following curative surgery.

METHODS

This was a 2-year prospective study conducted at a tertiary care centre in southern India. Baseline assessment included demographic details, mode of presentation, bone mineral biochemistry, BMD, trabecular bone score (TBS), and bone turnover markers (BTMs). These parameters were reassessed at the end of the first and second years following curative parathyroid surgery.

RESULTS

Fifty-one subjects (32 men and 19 women) with PHPT who had undergone curative parathyroidectomy were included in this study. The mean (SD) age was 44.6 (13.7) years. The TBS, BTMs, and BMD at lumbar spine and forearm were significantly worse at baseline in subjects with higher baseline PTH (≥250 pg/mL) when compared to the group with lower baseline PTH (<250 pg/mL). At the end of 2 years, the difference between high versus low PTH groups (mean ± SD) persisted only for forearm BMD (0.638±0.093 versus 0.698±0.041 g/cm²; P =.01). However, on follow-up visits in the first and second year after curative parathyroidectomy, there was no significant difference in BTMs, BMD at the femoral neck, lumbar spine, and TBS between the 2 groups stratified by baseline PTH.

CONCLUSION

The BMD at the forearm remained significantly worse in individuals with high baseline PTH even at 2 years after surgery, while other parameters including TBS improved significantly from baseline.

Toward identifying reproducible brain signatures of obsessive-compulsive profiles: rationale and methods for a new global initiative

BACKGROUND

Obsessive-compulsive disorder (OCD) has a lifetime prevalence of 2-3% and is a leading cause of global disability. Brain circuit abnormalities in individuals with OCD have been identified, but important knowledge gaps remain. The goal of the new global initiative described in this paper is to identify robust and reproducible brain signatures of measurable behaviors and clinical symptoms that are common in individuals with OCD. A global approach was chosen to accelerate discovery, to increase rigor and transparency, and to ensure generalizability of results.

METHODS

We will study 250 medication-free adults with OCD, 100 unaffected adult siblings of individuals with OCD, and 250 healthy control subjects at five expert research sites across five countries (Brazil, India, Netherlands, South Africa, and the U.S.). All participants will receive clinical evaluation, neurocognitive assessment, and magnetic resonance imaging (MRI). The imaging will examine multiple brain circuits hypothesized to underlie OCD behaviors, focusing on morphometry (T1-weighted MRI), structural connectivity (Diffusion Tensor Imaging), and functional connectivity (resting-state fMRI). In addition to analyzing each imaging modality separately, we will also use multi-modal fusion with machine learning statistical methods in an attempt to derive imaging signatures that distinguish individuals with OCD from unaffected siblings and healthy controls (Aim #1). Then we will examine how these imaging signatures link to behavioral performance on neurocognitive tasks that probe these same circuits as well as to clinical profiles (Aim #2). Finally, we will explore how specific environmental features (childhood trauma, socioeconomic status, and religiosity) moderate these brain-behavior associations.

DISCUSSION

Using harmonized methods for data collection and analysis, we will conduct the largest neurocognitive and multimodal-imaging study in medication-free subjects with OCD to date. By recruiting a large, ethno-culturally diverse sample, we will test whether there are robust biosignatures of core OCD features that transcend countries and cultures. If so, future studies can use these brain signatures to reveal trans-diagnostic disease dimensions, chart when these signatures arise during development, and identify treatments that target these circuit abnormalities directly. The long-term goal of this research is to change not only how we conceptualize OCD but also how we diagnose and treat it.

Laparoscopy-assisted ureterostomy- technique

INTRODUCTION

Urinary tract anomalies in children at times pose challenges in which immediate urinary diversion is required before definitive reconstruction. Open cutaneous ureterostomy technique is a well-established approach for this scenario. We describe the laparoscopy-assisted alternative.

MATERIAL AND METHODS

Transperitoneal laparoscopy is performed with three ports. One trans-umbilical 5mm port for vision and two 3mm working instruments, one of which is through the proposed ureterostomy site minimising scarring. The position of the third port is carefully checked both externally and internally. Laparoscopic identification of the dilated ureter is quick and easy. The redundant ureter is mobilised and excess excised if needed. The ureteric loop is then exteriorised and the ureterostomy fashioned externally. Proximal and distal patency is checked both externally and laparoscopically.

RESULTS

Nineteen patients underwent the procedure for primary VUR (n=6), neuropathic bladder 7, posterior urethral valve 4, and vesico-ureteric obstruction 2. The mean operative time was 40 minutes. the patients received three doses of perioperative antibiotics and were discharged in 72 hours (mean). At three months, clinical and ultrasound review have shown satisfactory and stable upper tracts and no episodes of UTI.

DISCUSSION

The laparoscopic view gives the benefit of direct visualisation and identification with adequate dissection in order to bring the ureter to the surface in a tensionless manner. A redundant ureter can be easily addressed to correct tortuosity or redundancy appropriately. Bladder drainage can be ensured with careful dissection of the distal ureter and inspection at the end of the procedure.

CONCLUSION

Laparoscopy-Assisted ureterostomy formation is easy and quick to perform. It is feasible even in the smallest of babies, assures the shortest segment of ureter to the bladder providing prompt drainage in a refluxing ureterostomy setting. Our early experience is promising with potential benefits.

Laparoscopic posterior appendix Mitrofanoff using the modified Shanfield anastomosis

Laparoscopic transperitoneal technique for appendicovesicostomy was performed in a 5-year-old boy with a non-neurogenic neuropathic bladder using a transumbilical 5-mm port, two 3-mm working ports and a modified Shanfield anastomosis. Posterior extramucosal detrusorotomy and submucosal dissection was performed. The proximal appendix was spatulated and advanced into the bladder through a mucosal window using a U-stitch and fixed. The detrusor was then approximated creating an antirefluxing extramucosal tunnel. VQ plasty was fashioned for stoma formation. The procedure and postoperative period were uneventful. Clean intermittent catheterisation (CIC) was established subsequently and continued for the last 6 months. Our experience shows that appendix Mitrofanoff can be performed with minimal number and size of ports, resulting in a good cosmetic outcome. A simplified anastomosis makes it less cumbersome, and catheterisation is reliable as there is no mucosa-mucosa junction to negotiate.

Mass media representation of suicide in a high suicide state in India: an epidemiological comparison with suicide deaths in the population

OBJECTIVES

Suicide rates in India are among the highest in the world, equating to over 200 000 suicides annually. Reports of suicides are a routine feature in major newspapers in India, and reporters may selectively present 'newsworthy' suicide stories. The aim of this paper was to systematically investigate whether mass media reports of suicides reflect the epidemiological data on suicide in a high suicide state in India.

DESIGN

We undertook a content analysis study to extract sociodemographic data on suicides reported among nine of the most highly read daily newspapers in the high suicide southern state of Tamil Nadu between June and December 2016. A total of 1258 newspaper articles were retrieved containing reports on 1631 suicides. Two-tailed binomial tests on aggregate frequencies assessed whether the sociodemographic characteristics of suicides in the newspaper articles were different to the population suicide statistics for Tamil Nadu.

RESULTS

We identified some statistically significant discrepancies between suicide characteristics in the population and the media. Suicides involving females (p<0.001), those aged under 30 years (p<0.001), separated or widowed males (p<0.001), unmarried females (p<0.001), those using methods with a higher case fatality rate (ie, hanging (p<0.001), jumping off high structures (p<0.001) and coming under vehicles (p<0.001) and those who were students (p<0.001) or working in the agricultural sector (p<0.001) were significantly over-reported relative to their occurrence in the broader population. Suicides involving men (p<0.001), those aged over 30 years and above (p<0.001), those who were married and suicides by poisoning (p<0.001) were significantly under-reported relative to their occurrence in the broader population.

CONCLUSIONS

The suicide characteristics in the print media were not entirely representative of suicides in the broader Tamil Nadu population, which may lead the general public to develop misunderstandings about suicide in their state. The discrepancies we identified will inform tailored suicide prevention education for media professionals.

Mid- to long-term outcomes of the 'anatomical approach' to congenital megaprepuce repair

INTRODUCTION

The understanding of the aetiopathogenesis and the long-term outcomes of correctional repair of congenital megaprepuce (CMP) remains unestablished. Different techniques have been described; however, optimum results have been difficult to achieve.

OBJECTIVE

The aim of our study was to review our experience of the 'anatomical approach' to the correction of CMP.

MATERIAL AND METHODS

This is a retrospective review of boys who underwent CMP repair between 2003 and 2014. All of them had the anatomical approach: A curved incision is made between the scrotal and penile skin. Circumferential dissection superficial to Buck's fascia frees the penis and allows the scrotum to assume a more caudal position. The dissection distally lifts the preputial sac that is opened ventrally. The redundant inner preputial skin is excised. After full degloving, the dorsal flap of skin is thinned. The base of the flap is anchored, and the rectangle of skin is wrapped around the shaft. The remaining diamond-shaped incision is closed in a vertical line. Postoperatively, foam dressings and urethral catheter are left in place. Symptomatology, hospital stay, postoperative complications, redosurgery, voiding and cosmesis were evaluated.

RESULTS

Sixty-one patients had surgery at 5-151 months (median 17 months). Median hospital stay was 24 h (12-168 h). Foam dressings and urethral catheter were used in 47 boys and removed in outpatient clinic after 3-7 days. There were two immediate postoperative complications requiring surgery. One due to severe oedema and constriction ring, and the other had wound infection with wound breakdown, both in patients with no dressings (P < 0.05). Follow-up was available for 58 patients, with a median of 22 months (3-79 months). Two required redosurgery (3.5%), one with poor cosmetic result and one recurrence. In all patients, a normal circumcised appearance had been achieved and in 47, cosmetic result was excellent (81%). Five patients have residual suprapubic fat, and four, excess ventral skin. One with residual suprapubic fat has reached puberty and it has resolved. All declared good stream. The same technique was used for six patients with poor cosmetic result after surgery elsewhere. The outcome is excellent for all, with median follow-up of 20.5 months (5-31 months).

CONCLUSION

The 'anatomical' repair provides the ability to create the appearance of a standard circumcision, which is generally accepted as normality. Apart from the penis itself, this technique facilitates correction of the penoscrotal transposition, giving the external genitalia the best appearance. It seems to provide good functional and cosmetic outcomes, and it holds true at mid- to long-term follow-up. Dressings and catheter can potentially prevent postoperative complications. However, a prospective study with standardised parameters is required to confirm these findings.

Abstract P5-07-05: Obesity, adipose inflammation, and race in patients with early stage breast cancer

Background: Elevated body mass index (BMI) is associated with increased risk of estrogen receptor-positive postmenopausal breast cancer. Mechanistically, most individuals with elevated BMI have breast white adipose tissue inflammation (WATi) which confers increased breast cancer risk, particularly in those with existing benign breast disease. Individuals with WATi have elevated in-breast expression of aromatase and several systemic changes that increase breast cancer risk, including hyperinsulinemia and higher levels of C-reactive protein. However, women with normal BMI but high levels of body fat are also likely to harbor WATi and are at increased risk of postmenopausal breast cancer. The accuracy of BMI for assessing adiposity and predicting obesity-related disorders, including cancer, varies across race and ethnicity. Whether the association between BMI and WATi varies by race is unknown. Here we aimed to characterize relationships among breast WATi and clinicopathologic features in a racially diverse cohort undergoing mastectomy for breast cancer treatment.

Methods: Non-tumorous breast tissue and fasting blood were collected from women undergoing mastectomy for breast cancer treatment or prevention at a single center serving a racially diverse patient population. Breast WATi was detected by the presence of crown-like structures in the breast (CLS-B), which are composed of a dead/dying adipocyte surrounded by CD68+ macrophages. Clinicopathologic data were abstracted from electronic medical records. Associations among categorical variables were examined using Fisher's exact test. Relationships between continuous variables were examined using the Spearman correlation.

Results: As of May 18, 2018 62 patients have been accrued; median age 55 (range 32 to 84). Self-reported race distribution was: 36 (58%) Asian, 5 African American (8%), 20 (32%) Caucasian, and 1 (2%) unknown. Breast tissue has been analyzed for WATi in 60 cases thus far. Clinicopathologic features stratified by the presence or absence of breast WATi are presented in. Breast WAT inflammation was associated with obesity (P=0.02) and a trend to association was observed with dyslipidemia (P&lt;0.09).

Conclusions: Breast adipose inflammation is associated with elevated BMI and possibly metabolic syndrome disorders in a racially diverse population. These findings are consistent with observations from predominantly Caucasian cohorts. Race-specific characteristics will also be examined. Study accrual is ongoing and updated results will be presented.

External stent in laparoscopic pyeloplasty: The K-wire technique

The majority of surgeons leave internal stents following laparoscopic pyeloplasty, which necessitates a second anaesthetic for removal. A novel technique of placing external nephro-ureteric stents, thus obviating a second procedure for retrieval, is shown in this video bank. As demonstrated in the video, a Kirschner wire (K-wire) is used to thread the stent in place. Although, there are few reports of using externalised stents in laparoscopic pyeloplasty, it is believed that this technique has not been previously described. So far this technique has been used in 22 patients without any stent-related complications. The technique is feasible, safe and reproducible. It obviates the need for a further anaesthetic and avoids potential risks of another procedure. Secondary benefits include avoiding another hospital admission.

Hydronephrotic kidney with multiple extra-renal calyces

Extra-renal calyces are a rare anomaly of the renal collecting system, characterised by the presence of calyces and pelvis outside the renal parenchyma. It may also be associated with other anomalies, such as renal ectopia, fusion and malrotation. We describe an unusual case of extra-renal calyces with six long calyces arising from a suspected multicystic dysplastic kidney that was successfully managed laparoscopically.

Global minimally invasive pyeloplasty study in children: Results from the Pediatric Urology Expert Group of the European Association of Urology Young Academic Urologists working party

INTRODUCTION

Minimally invasive pyeloplasty (MIP) for ureteropelvic junction (UPJ) obstruction in children has gained popularity over the past decade as an alternative to open surgery. The present study aimed to identify the factors affecting complication rates of MIP in children, and to compare the outcomes of laparoscopic (LP) and robotic-assisted laparoscopic pyeloplasty (RALP).

MATERIALS AND METHODS

The perioperative data of 783 pediatric patients (<18 years old) from 15 academic centers who underwent either LP or RALP with an Anderson Hynes dismembered pyeloplasty technique were retrospectively evaluated. Redo cases and patients with anatomic renal abnormalities were excluded. Demographics and operative data, including procedural factors, were collected. Complications were classified according to the Satava and modified Clavien systems. Failure was defined as any of the following: obstructive parameters on diuretic renal scintigraphy, decline in renal function, progressive hydronephrosis, or symptom relapse. Univariate and multivariate analysis were applied to identify factors affecting the complication rates. All parameters were compared between LP and RALP.

RESULTS

A total of 575 children met the inclusion criteria. Laparoscopy, increased operative time, prolonged hospital stay, ureteral stenting technique, and time required for stenting were factors influencing complication rates on univariate analysis. None of those factors remained significant on multivariate analysis. Mean follow-up was 12.8 ± 9.8 months for RALP and 45.2 ± 33.8 months for LP (P = 0.001). Hospital stay and time for stenting were shorter for robotic pyeloplasty (P < 0.05 for both). Success rates were similar between RALP and LP (99.5% vs 97.3%, P = 0.11). The intraoperative complication rate was comparable between RALP and LP (3.8% vs 7.4%, P = 0.06). However, the postoperative complication rate was significantly higher in the LP group (3.2% for RALP and 7.7% for LP, P = 0.02). All complications were of no greater severity than Satava Grade IIa and Clavien Grade IIIb.

DISCUSSION

This was the largest multicenter series of LP and RALP in the pediatric population. Limitations of the study included the retrospective design and lack of surgical experience as a confounder.

CONCLUSIONS

Both minimally invasive approaches that were studied were safe and highly effective in treating UPJ obstruction in children in many centers globally. However, shorter hospitalization time and lower postoperative complication rates with RALP were noted. The aims of the study were met.

Plasma cytokine abnormalities in drug-naïve, comorbidity-free obsessive-compulsive disorder

Growing evidence in the last decade suggest significant role of immune alterations in the pathogenesis of obsessive-compulsive disorder (OCD). Cytokines, mediators of inflammation, alter the neurotransmitter concentration and result in a hyposerotonergic and hyperglutamatergic state implicated in pathogenesis of OCD. However, only few studies have examined cytokine abnormalities in OCD with inconsistent results possibly due to confounding effects of medications and comorbid anxiety-depression. We examined 20 comorbidity free, drug free OCD patients and 20 age and sex matched healthy controls. Clinical severity was assessed using Yale Brown Obsessive Compulsive Scale, Hamilton anxiety rating scale, Hamilton depression rating scale and Clinical Global Impression. Levels of different cytokines, Interleukin (IL)-2, IL-4, IL-6, IL-10, Tumor necrosis factor (TNF)-α and Interferon (IFN)-γ were assessed using Cytometric Bead Array. OCD patients had significantly greater plasma levels of IL-2, IL-4, IL-6, IL-10 and TNF-α levels than controls but not IFN-γ. Reanalysis of data with only drug naïve patients (excluding 4 drug free patients) did not alter the results. Presence of these abnormalities in drug-naïve patients suggests the possible role of cytokines in the pathogenesis of OCD. Study findings have potential clinical utility in development of novel therapeutic options targeting cytokine aberrations in OCD.

Single incision retro-peritoneoscopic paediatric nephrectomy: early experience

Single incision, single port, or single site surgery for retro-peritoneoscopic nephrectomy and nephro-ureterectomy in paediatric practice using an advanced access platform (GelPOINT Mini) is described in two patients. One patient had bilateral synchronous nephrectomy. The technique, advantages, and challenges are reported. Beyond the initial hurdles and learning curve, this technique is promising and has the potential to be extended to other procedures in paediatric urology.

Primary bladder exstrophy closure in neonates: challenging the traditions

PURPOSE

We describe a novel approach to neonatal bladder exstrophy closure that challenges the role of postoperative immobilization and pelvic osteotomy.

MATERIALS AND METHODS

We reviewed the primary management of bladder exstrophy at our institutions between 2007 and 2011. In particular we compared postoperative management in the surgical ward using epidural analgesia to muscle paralysis and ventilation in the intensive care unit. Clinical outcome measures were time to full feed, length of stay, postoperative complications and redo closure. Cost-effectiveness was also evaluated using hospital financial data. Data are expressed as median (range). Significance was explored by Fisher exact test and unpaired t-test.

RESULTS

A total of 74 patients underwent primary closure without osteotomy. Successful closure was achieved in 70 patients (95%). A total of 48 cases (65%) were managed on the ward (group A) and 26 (35%) were transferred to the intensive care unit (group B). The 2 groups were homogeneous for gestational age (median 39 weeks, range 27 to 41) and age at closure (3 days, 1 to 152). Complications requiring surgical treatment were noted in 4 patients (8.3%) in group A and 3 (11.5%) in group B (p = 0.609). Length of stay was significantly shorter for the group managed on the ward (11 vs 18 days, p <0.0001). Median costs were $42,732 for patients admitted to the intensive care unit and $16,214 for those admitted directly to the surgical ward (p <0.0001).

CONCLUSIONS

Primary closure of bladder exstrophy without lower limb immobilization and osteotomy is feasible. Postoperative care on the surgical ward using epidural analgesia results in shorter hospitalization.

We present a case of a 27-year-old Royal Marine with a massive pericardial effusion, presenting with minimal clinical findings, suggesting that high levels of physical fitness may effectively mask the normal symptoms of this potentially life-threatening condition.

Combined laparoscopic and cystoscopic injection sclerotherapy for bladder venous malformation: a novel technique

Treatment of vascular malformations of the urinary bladder can be challenging. We report a case of bladder venous malformation treated with sodium tetradecyl sulphate (STS 3%) sclerotherapy, using a combined cystoscopic and percutaneous transperitoneal laparoscopy guided approach. When cystoscopic views are poor, the laparoscopic approach is a useful adjunct to aid sclerotherapy of bladder venous malformation. This technique has not been previously described.

Ileal bladder augmentation and vitamin B12: levels decrease with time after surgery

OBJECTIVE

We investigated vitamin B12 deficiency following ileocystoplasty in children.

METHODS

Patients who underwent ileocystoplasty between December 1993 and September 2006 were included and B12 levels were retrospectively analysed. Patients with a serum B12 of less than 150 pg/ml were considered deficient. The distance of the ileal segment from the ileocaecal valve was recorded.

RESULTS

There were 105 patients in the series; 61 were male. Mean age at surgery was 7.7 years (SD = 3.9). The mean interval from surgery to most recent B12 level was 50 months (SD = 30). None of the patients were on B12 supplementation. Two patients were B12 deficient, both more than 7 years after surgery; 44% of patients with levels available 7 years after surgery had a B12 below 300 pg/ml. There was a significant negative correlation between B12 level and length of follow up (Spearman's rank, P < 0.01). Twenty patients with an ileal segment sparing 60 cm from the ileocaecal valve had a higher mean B12 (524 vs 419, SEM 60 vs 28). This was not statistically significant.

CONCLUSION

We demonstrate a reduction in serum B12 level with time following ileocystoplasty. These patients should have their B12 levels measured in the long term.

A randomized control trial comparing two enteral feeding volumes in very low birth weight babies

Poor post-natal growth of preterm neonates is common and fortification is recommended. However, this is not always practical in low-resource areas. Hypothesizing that increasing the volume of feeds would be safe and lead to better post-natal weight gain, we randomized 64 babies with birth weight <1500 g, once they reached full feeds, to continue feeds at 200 ml/kg/day (standard volume) or increase to 300 ml/kg/day (high volume) of expressed breast milk. There was a significantly higher daily weight gain in the high-volume group as compared to the standard volume group (24.9 vs. 18.7 g/kg/day, p < 0.0001). There were no differences in complications like feed intolerance, tachypnoea, sepsis, patent ductus arteriosus or necrotizing enterocolitis. High-volume feeds at 300 ml/kg/day was safe and resulted in better weight gain than standard volume feeds in very low birth weight babies.

Intracranial hypertension with delayed puberty: a rare presentation of juvenile onset systemic lupus erythematosus

An adolescent boy presented with headache, bilateral papilloedema, growth retardation and absent secondary sexual characteristics. The diagnosis of intracranial hypertension was confirmed by increased intracranial pressure and normal neuroimaging of the brain except for partial empty sella and prominent perioptic cerebrospinal fluid (CSF) spaces. Evaluation showed an erythrocyte sedimentation rate of 150 mm/hr, positive antinuclear antibody, anti-dsDNA and antiribosomal P protein. Renal biopsy revealed diffuse segmental proliferative lupus nephritis (LN) class IV-S (A), which confirmed the diagnosis of systemic lupus erythematosus (SLE). Treatment of LN with intravenous pulse methylprednisolone and cyclophosphamide normalised the patient's CSF pressure and symptoms. In cases of intracranial hypertension, SLE must be considered. Growth retardation and absence of secondary sexual characteristics could coexist and may be presenting features of SLE. These manifestations point to advanced grades of LN, which could be asymptomatic and may be missed without a renal biopsy.

Motor cortical prediction of EMG: evidence that a kinetic brain-machine interface may be robust across altered movement dynamics

During typical movements, signals related to both the kinematics and kinetics of movement are mutually correlated, and each is correlated to some extent with the discharge of neurons in the primary motor cortex (M1). However, it is well known, if not always appreciated, that causality cannot be inferred from correlations. Although these mutual correlations persist, their nature changes with changing postural or dynamical conditions. Under changing conditions, only signals directly controlled by M1 can be expected to maintain a stable relationship with its discharge. If one were to rely on noncausal correlations for a brain-machine interface, its generalization across conditions would likely suffer. We examined this effect, using multielectrode recordings in M1 as input to linear decoders of both end point kinematics (position and velocity) and proximal limb myoelectric signals (EMG) during reaching. We tested these decoders across tasks that altered either the posture of the limb or the end point forces encountered during movement. Within any given task, the accuracy of the kinematic predictions tended to be somewhat better than the EMG predictions. However, when we used the decoders developed under one task condition to predict the signals recorded under different postural or dynamical conditions, only the EMG decoders consistently generalized well. Our results support the view that M1 discharge is more closely related to kinetic variables like EMG than it is to limb kinematics. These results suggest that brain-machine interface applications using M1 to control kinetic variables may prove to be more successful than the more standard kinematic approach.

Central nervous system tuberculosis

Central nervous system (CNS) involvement, one of the most devastating clinical manifestations of tuberculosis (TB) is noted in 5 to 10% of extrapulmonary TB cases, and accounts for approximately 1% of all TB cases. Definitive diagnosis of tuberculous meningitis (TBM) depends upon the detection of the tubercle bacilli in the CSF. Every patient with TBM should preferably be evaluated by imaging with contrast enhanced CT either before or within the first 48 hours of treatment. An extra-neural focus of tuberculosis should be sought clinically and radiologically in all patients with CNS TB as it may indicate safer and more accessible sites for diagnostic samplings. A minimum of 10 months treatment is warranted, prompted by the uncertain influences of disease severity, CNS drug penetration, undetected drug resistance and patient compliance. All patients with TB meningitis may receive adjunctive corticosteroids at presentation regardless of disease severity even for those with HIV infection. Drug resistance is strongly associated with previous treatment. The key principle of managing drug-resistant TB is never to add a single drug to a failing regimen. Early ventriculo-peritoneal shunting should be considered in those with hydrocephalus failing medical management. The single most important determinant of outcome is the stage of tuberculous meningitis at which treatment has been started.

Strong purified protein derivative responses are associated with poor mycobacterium inhibition in latent TB

The tuberculin skin test (TST) using purified protein derivative (PPD) of Mycobacterium tuberculosis is traditionally used to diagnose latent tuberculosis (TB) infection (LTBI). However, LTBI diagnosis by peripheral blood mononuclear cell (PBMC) interferon (IFN)-gamma responses to M. tuberculosis-specific antigens, early secreted antigenic target 6 kDa (ESAT-6) and culture filtrate protein (CFP)-10 has greater specificity. We investigated the difference in antimycobacterium cellular immunity in TB contacts who were strong TST reactors but nonresponsive to the ESAT-6/CFP-10 assay compared with those with concordant results. Healthy TB contacts were tested using the above two assays and mycobacterium survival was measured after co-culture of infected macrophages with their PBMCs. Whether PPD reactivity was tested by TST or by PBMC-specific IFN-gamma responses, strongly PPD-reactive TB contacts without ESAT-6/CFP-10 responsiveness showed significantly better mycobacterium inhibition activity than ESAT-6/CFP-10-responsive TB contacts with the same PPD reactivity. In the former group, stronger PPD reactivity was associated with improved mycobacterium killing, whereas ESAT-6/CFP-10 responders showed the opposite result. PPD-reactive ESAT-6/CFP-10-nonresponsive TB contacts in our population may have had protective immunity related to prior mycobacterium exposure. ESAT-6/CFP10-responsive TB contacts are more likely to have LTBI and, in this group, strong PPD reactivity may paradoxically be associated with poor mycobactericidal activity.

Low-flow anaesthesia at a fixed flow rate

AIMS AND OBJECTIVES

This study attempts to assess the safety of low-flow anaesthesia (LFA) at fixed flow rates with particular reference to the incidence of a decline in FiO(2) below safe levels of 0.3 and to determine whether LFA can be used safely in the absence of an FiO(2) monitor.

METHODS

A total of 100 patients undergoing procedures under general anaesthesia at fresh gas flows of 300 ml/min of O(2) and 300 ml/min of N(2)O were monitored while maintaining the dial setting of isoflurane at 1.5% for 2 h. The changes in gas composition were analysed and even a single recording of FiO(2) of <0.3 was considered sufficient to render the technique unsafe in the absence of gas monitors.

RESULTS

The lowest recorded value of FiO(2) was 31% (v/v%). There was no incidence of adverse events necessitating the conversion from low flows to conventional flows.

CONCLUSIONS

We conclude that low flows of 300 ml/min of N(2)O and 300 ml/min of oxygen can be used safely for a period of 2 h without the use of monitors for gas analysis of oxygen and agent in adult patients weighing between 40 and 75 kgs.

Splenogonadal fusion: a rare cause of testicular enlargement

Splenogonadal fusion is a rare congenital abnormality found in boys and girls. There is fusion of the developing splenic anlage and the gonadal mesoderm at approximately week 5 of intrauterine life. It commonly presents as a testicular mass treated with an unnecessary orchidectomy. We report two cases of the discontinuous type presenting with testicular swelling and review the literature.

Thoracoscopic repair of diaphragmatic eventration

We report a 6-month-old child who presented with recurrent chest infections associated with a right diaphragmatic eventration. Failure in conservative management lead to thoracoscopic plication at 17 months of age and discharge on the third postoperative day. At one year followup he is completely free from all symptoms, and his chest x-ray demonstrates a marked improvement in the position of the diaphragm. We recommend thoracoscopy as a viable approach in treating this condition in children.

Small bowel volvulus due to giant mesenteric lipoma

We report on a 14-year-old girl with acute intestinal obstruction due to volvulus of the small bowel caused by a giant mesenteric lipoma. To the best of our knowledge, this presentation of a mesenteric lipoma is unknown in the previous paediatric literature.

Maternal depression and low maternal intelligence as risk factors for malnutrition in children: a community based case-control study from South India

AIMS

To determine whether current and postpartum maternal depression and low maternal intelligence are risk factors for malnutrition in children.

METHODS

In rural South India 72 children with malnutrition were identified from a central register; 72 controls were matched for age, gender, and residence.

RESULTS

Major depression in the postpartum period (OR 5.0, 95% CI 1.0 to 24.0), current major depression (OR 3.2, 95% CI 1.1 to 9.5), and low maternal intelligence (OR 3.8, 95% CI 1.3 to 11.1) were associated with malnutrition in the child. Low birth weight (OR 2.9, 95% CI 1.2 to 6.8) was also significantly associated with infant malnutrition. Conditional logistic regression adjusting for all other determinants yielded the following results: major depression during the postpartum period (OR 7.8; 95% CI 1.6 to 38.51), current major depression (OR 3.1; 95% CI 0.9 to 9.7), low maternal intelligence (OR 4.6; 95% CI 1.5 to 14.1), and low birth weight (OR 2.7; 95% CI 2.5 to 6.8). The interactions between current maternal depression and low birth weight and between postpartum depression and low maternal intelligence were statistically significant. The level of maternal intelligence was associated with nutritional status. The severity of malnutrition was also significantly associated with major depression during the postpartum period and low maternal intelligence.

CONCLUSION

There is evidence for an association between postpartum maternal depression, low maternal intelligence, and low birth weight with malnutrition in children aged 6-12 months.
