Abstract
Importance The association between place of birth and hypothermic neuroprotection after hypoxic-ischemic encephalopathy (HIE) in low- and middle-income countries (LMICs) is unknown. Objective To ascertain the association between place of birth and the efficacy of whole-body hypothermia for protection against brain injury measured by magnetic resonance (MR) biomarkers among neonates born at a tertiary care center (inborn) or other facilities (outborn). Design, Setting, and Participants This nested cohort study within a randomized clinical trial involved neonates at 7 tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh between August 15, 2015, and February 15, 2019. A total of 408 neonates born at or after 36 weeks' gestation with moderate or severe HIE were randomized to receive whole-body hypothermia (reduction of rectal temperatures to between 33.0 °C and 34.0 °C; hypothermia group) for 72 hours or no whole-body hypothermia (rectal temperatures maintained between 36.0 °C and 37.0 °C; control group) within 6 hours of birth, with follow-up until September 27, 2020. Exposure 3T MR imaging, MR spectroscopy, and diffusion tensor imaging. Main Outcomes and Measures Thalamic N-acetyl aspartate (NAA) mmol/kg wet weight, thalamic lactate to NAA peak area ratios, brain injury scores, and white matter fractional anisotropy at 1 to 2 weeks and death or moderate or severe disability at 18 to 22 months. Results Among 408 neonates, the mean (SD) gestational age was 38.7 (1.3) weeks; 267 (65.4%) were male. A total of 123 neonates were inborn and 285 were outborn. Inborn neonates were smaller (mean [SD], 2.8 [0.5] kg vs 2.9 [0.4] kg; P = .02), more likely to have instrumental or cesarean deliveries (43.1% vs 24.7%; P = .01), and more likely to be intubated at birth (78.9% vs 29.1%; P = .001) than outborn neonates, although the rate of severe HIE was not different (23.6% vs 17.9%; P = .22). Magnetic resonance data from 267 neonates (80 inborn and 187 outborn) were analyzed. In the hypothermia vs control groups, the mean (SD) thalamic NAA levels were 8.04 (1.98) vs 8.31 (1.13) among inborn neonates (odds ratio [OR], -0.28; 95% CI, -1.62 to 1.07; P = .68) and 8.03 (1.89) vs 7.99 (1.72) among outborn neonates (OR, 0.05; 95% CI, -0.62 to 0.71; P = .89); the median (IQR) thalamic lactate to NAA peak area ratios were 0.13 (0.10-0.20) vs 0.12 (0.09-0.18) among inborn neonates (OR, 1.02; 95% CI, 0.96-1.08; P = .59) and 0.14 (0.11-0.20) vs 0.14 (0.10-0.17) among outborn neonates (OR, 1.03; 95% CI, 0.98-1.09; P = .18). There was no difference in brain injury scores or white matter fractional anisotropy between the hypothermia and control groups among inborn or outborn neonates. Whole-body hypothermia was not associated with reductions in death or disability, either among 123 inborn neonates (hypothermia vs control group: 34 neonates [58.6%] vs 34 [56.7%]; risk ratio, 1.03; 95% CI, 0.76-1.41), or 285 outborn neonates (hypothermia vs control group: 64 neonates [46.7%] vs 60 [43.2%]; risk ratio, 1.08; 95% CI, 0.83-1.41). Conclusions and Relevance In this nested cohort study, whole-body hypothermia was not associated with reductions in brain injury after HIE among neonates in South Asia, irrespective of place of birth. These findings do not support the use of whole-body hypothermia for HIE among neonates in LMICs. Trial Registration ClinicalTrials.gov Identifier: NCT02387385.

Abstract
BACKGROUND Although therapeutic hypothermia reduces death or disability after neonatal encephalopathy in high-income countries, its safety and efficacy in low-income and middle-income countries is unclear. We aimed to examine whether therapeutic hypothermia alongside optimal supportive intensive care reduces death or moderate or severe disability after neonatal encephalopathy in south Asia. METHODS We did a multicountry open-label, randomised controlled trial in seven tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh. We enrolled infants born at or after 36 weeks of gestation with moderate or severe neonatal encephalopathy and a need for continued resuscitation at 5 min of age or an Apgar score of less than 6 at 5 min of age (for babies born in a hospital), or both, or an absence of crying by 5 min of age (for babies born at home). Using a web-based randomisation system, we allocated infants into a group receiving whole body hypothermia (33·5°C) for 72 h using a servo-controlled cooling device, or to usual care (control group), within 6 h of birth. All recruiting sites had facilities for invasive ventilation, cardiovascular support, and access to 3 Tesla MRI scanners and spectroscopy. Masking of the intervention was not possible, but those involved in the magnetic resonance biomarker analysis and neurodevelopmental outcome assessments were masked to the allocation. The primary outcome was a combined endpoint of death or moderate or severe disability at 18-22 months, assessed by the Bayley Scales of Infant and Toddler Development (third edition) and a detailed neurological examination. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT02387385. FINDINGS We screened 2296 infants between Aug 15, 2015, and Feb 15, 2019, of whom 576 infants were eligible for inclusion. After exclusions, we recruited 408 eligible infants and we assigned 202 to the hypothermia group and 206 to the control group. Primary outcome data were available for 195 (97%) of the 202 infants in the hypothermia group and 199 (97%) of the 206 control group infants. 98 (50%) infants in the hypothermia group and 94 (47%) infants in the control group died or had a moderate or severe disability (risk ratio 1·06; 95% CI 0·87-1·30; p=0·55). 84 infants (42%) in the hypothermia group and 63 (31%; p=0·022) infants in the control group died, of whom 72 (36%) and 49 (24%; p=0·0087) died during neonatal hospitalisation. Five serious adverse events were reported: three in the hypothermia group (one hospital readmission relating to pneumonia, one septic arthritis, and one suspected venous thrombosis), and two in the control group (one related to desaturations during MRI and other because of endotracheal tube displacement during transport for MRI). No adverse events were considered causally related to the study intervention. INTERPRETATION Therapeutic hypothermia did not reduce the combined outcome of death or disability at 18 months after neonatal encephalopathy in low-income and middle-income countries, but significantly increased death alone. Therapeutic hypothermia should not be offered as treatment for neonatal encephalopathy in low-income and middle-income countries, even when tertiary neonatal intensive care facilities are available.

Abstract
A rapid and early diagnostic test to identify the encephalopathic babies at risk of adverse outcome may accelerate the development of neuroprotectants. We examined if a whole blood transcriptomic signature measured soon after birth, predicts adverse neurodevelopmental outcome eighteen months after neonatal encephalopathy. We performed next generation sequencing on whole blood ribonucleic acid obtained within six hours of birth from the first 47 encephalopathic babies recruited to the Hypothermia for Encephalopathy in Low and middle-income countries (HELIX) trial. Two infants with blood culture positive sepsis were excluded, and the data from remaining 45 were analysed. A total of 855 genes were significantly differentially expressed between the good and adverse outcome groups, of which RGS1 and SMC4 were the most significant. Biological pathway analysis adjusted for gender, trial randomisation allocation (cooling therapy versus usual care) and estimated blood leukocyte proportions revealed over-representation of genes from pathways related to melatonin and polo-like kinase in babies with adverse outcome. These preliminary data suggest that transcriptomic profiling may be a promising tool for rapid risk stratification in neonatal encephalopathy. It may provide insights into biological mechanisms and identify novel therapeutic targets for neuroprotection.

Abstract
BACKGROUND Although thalamic magnetic resonance (MR) spectroscopy (MRS) accurately predicts adverse outcomes after neonatal encephalopathy, its utility in infants without MR visible deep brain nuclei injury is not known. We examined thalamic MRS metabolite perturbations in encephalopathic infants with white matter (WM) injury with or without cortical injury and its associations with adverse outcomes. METHODS We performed a subgroup analysis of all infants recruited to the MARBLE study with isolated WM or mixed WM/cortical injury, but no visible injury to the basal ganglia/thalamus (BGT) or posterior limb of the internal capsule (PLIC). We used binary logistic regression to examine the association of MRS biomarkers with three outcomes (i) WM injury score (1 vs. 2/3); (ii) cortical injury scores (0/1 vs. 2/3); and (iii) adverse outcomes (defined as death, moderate/severe disability) at two years (yes/no). We also assessed the accuracy of MRS for predicting adverse outcome. FINDINGS Of the 107 infants included in the analysis, five had adverse outcome. Reduced thalamic N-acetylaspartate concentration [NAA] (odds ratio 0.4 (95% CI 0.18-0.93)) and elevated thalamic Lactate/NAA peak area ratio (odds ratio 3.37 (95% CI 1.45-7.82)) were significantly associated with higher WM injury scores, but not with cortical injury. Thalamic [NAA] (≤5.6 mmol/kg/wet weight) had the best accuracy for predicting adverse outcomes (sensitivity 1.00 (95% CI 0.16-1.00); specificity 0.95 (95% CI 0.84-0.99)). INTERPRETATION Thalamic NAA is reduced in encephalopathic infants without MR visible deep brain nuclei injury and may be a useful predictor of adverse outcomes.

Abstract
OBJECTIVE To examine the effect of therapeutic hypothermia on MR biomarkers and neurodevelopmental outcomes in babies with mild hypoxic-ischaemic encephalopathy (HIE). DESIGN Non-randomised cohort study. SETTING Eight tertiary neonatal units in the UK and the USA. PATIENTS 47 babies with mild HIE on NICHD neurological examination performed within 6 hours after birth. INTERVENTIONS Whole-body cooling for 72 hours (n=32) or usual care (n=15; of these 5 were cooled for <12 hours). MAIN OUTCOME MEASURES MRI and MR spectroscopy (MRS) within 2 weeks after birth, and a neurodevelopmental outcome assessment at 2 years. RESULTS The baseline characteristics in both groups were similar except for lower 10 min Apgar scores (p=0.02) in the cooled babies. Despite this, the mean (SD) thalamic NAA/Cr (1.4 (0.1) vs 1.6 (0.2); p<0.001) and NAA/Cho (0.67 (0.08) vs 0.89 (0.11); p<0.001) ratios from MRS were significantly higher in the cooled group. Cooled babies had lower white matter injury scores than non-cooled babies (p=0.02). Four (27%) non-cooled babies with mild HIE developed seizures after 6 hours of age, while none of the cooled babies developed seizures (p=0.008). Neurodevelopmental outcomes at 2 years were available in 40 (85%) of the babies. Adverse outcomes were seen in 2 (14.3%) non-cooled babies, and none of the cooled babies (p=0.09). CONCLUSIONS Therapeutic hypothermia may have a neuroprotective effect in babies with mild HIE, as demonstrated by improved MRS biomarkers and reduced white matter injury on MRI. This may warrant further evaluation in adequately powered randomised controlled trials.

Abstract
Effective communication, team working and human factors are given little attention in traditional medical curricula. However, these skills are fundamentally important during crisis resource management (CRM) in healthcare. These skills can be learnt and can be taught very effectively within a simulated environment. Thus simulation-based training on CRM can positively impact patient safety. One such course which focuses on the management of common neonatal emergencies is the ‘Neonatal Emergencies Simulation Team training’ (NEST) program. This one day multiprofessional educational program, originally designed by the London Neonatal Transfer Service, aims to develop multidisciplinary confidence and competence in the management of common neonatal emergencies. This program has been evaluated positively in India, Nepal, Saudi Arabia and the UK and shows promise for wider implementation in high-, middle- and lowincome countries. Here we give an overview of the program and its implications. Citation: Mohinuddin S, Rajkumar Rajendram R, Swamy S.

Abstract
Background In neonatal encephalopathy, the clinical manifestations of injury can only be reliably assessed several years after an intervention, complicating early prognostication and rendering trials of promising neuroprotectants slow and expensive. We aimed to determine the accuracy of thalamic proton magnetic resonance (MR) spectroscopy (MRS) biomarkers as early predictors of the neurodevelopmental abnormalities observed years after neonatal encephalopathy. Methods We did a prospective multicentre cohort study across eight neonatal intensive care units in the UK and USA, recruiting term and near-term neonates who received therapeutic hypothermia for neonatal encephalopathy. We excluded infants with life-threatening congenital malformations, syndromic disorders, neurometabolic diseases, or any alternative diagnoses for encephalopathy that were apparent within 6 h of birth. We obtained T1-weighted, T2-weighted, and diffusion-weighted MRI and thalamic proton MRS 4–14 days after birth. Clinical neurodevelopmental tests were done 18–24 months later. The primary outcome was the association between MR biomarkers and an adverse neurodevelopmental outcome, defined as death or moderate or severe disability, measured using a multivariable prognostic model. We used receiver operating characteristic (ROC) curves to examine the prognostic accuracy of the individual biomarkers. This trial is registered with ClinicalTrials.gov, number NCT01309711. Findings Between Jan 29, 2013, and June 25, 2016, we recruited 223 infants who all underwent MRI and MRS at a median age of 7 days (IQR 5–10), with 190 (85%) followed up for neurological examination at a median age of 23 months (20–25). Of those followed up, 31 (16%) had moderate or severe disability, including one death. Multiple logistic regression analysis could not be done because thalamic N-acetylaspartate (NAA) concentration alone accurately predicted an adverse neurodevelopmental outcome (area under the curve [AUC] of 0·99 [95% CI 0·94–1·00]; sensitivity 100% [74–100]; specificity 97% [90–100]; n=82); the models would not converge when any additional variable was examined. The AUC (95% CI) of clinical examination at 6 h (n=190) and at discharge (n=167) were 0·72 (0·65–0·78) and 0·60 (0·53–0·68), respectively, and the AUC of abnormal amplitude integrated EEG at 6 h (n=169) was 0·73 (0·65–0·79). On conventional MRI (n=190), cortical injury had an AUC of 0·67 (0·60–0·73), basal ganglia or thalamic injury had an AUC of 0·81 (0·75–0·87), and abnormal signal in the posterior limb of internal capsule (PLIC) had an AUC of 0·82 (0·76–0·87). Fractional anisotropy of PLIC (n=65) had an AUC of 0·82 (0·76–0·87). MRS metabolite peak-area ratios (n=160) of NAA–creatine (<1·29) had an AUC of 0·79 (0·72–0·85), of NAA–choline had an AUC of 0·74 (0·66–0·80), and of lactate–NAA (>0·22) had an AUC of 0·94 (0·89–0·97). Interpretation Thalamic proton MRS measures acquired soon after birth in neonatal encephalopathy had the highest accuracy to predict neurdevelopment 2 years later. These methods could be applied to increase the power of neuroprotection trials while reducing their duration. Funding National Institute for Health Research UK.

Abstract
SUMMARY Inflammatory myofibroblastic tumours (IMTs) are rare and clinically benign in childhood, and malignant in adults. The aetiology of IMTs is not clear, and recent studies report it as true neoplasm rather than a reactive or inflammatory lesion. IMTs can involve any part of the body, but are usually common in lungs. These are rarely seen in adults and tracheal involvement is also rare in both adults and children. We describe an 18-year-old woman who presented with respiratory difficulty to the emergency department. On clinical examination, the patient had complete absence of breath sounds on the right side of the chest. CT of the chest and virtual bronchoscopy revealed a polypoidal soft tissue mass lesion involving the carina with occlusion of right main bronchus. Endoscopic-assisted resection was performed under general anaesthesia and the final pathological diagnosis was tracheal IMT.

Abstract
UNLABELLED Although therapeutic hypothermia (TH) is the standard of care for hypoxic ischaemic encephalopathy in high-income countries, the safety and efficacy of this therapy in low-income and middle-income countries (LMICs) is unknown. We aimed to describe the feasibility of TH using a low-cost servo-controlled cooling device and the short-term outcomes of the cooled babies in LMIC. DESIGN We recruited babies with moderate or severe hypoxic ischaemic encephalopathy (aged <6 hours) admitted to public sector tertiary neonatal units in India over a 28-month period. We administered whole-body cooling (set core temperature 33.5°C) using a servo-controlled device for 72 hours, followed by passive rewarming. We collected the data on short-term neonatal outcomes prior to hospital discharge. RESULTS Eighty-two babies were included-61 (74%) had moderate and 21 (26%) had severe encephalopathy. Mean (SD) hypothermia cooling induction time was 1.7 hour (1.5) and the effective cooling time 95% (0.08). The mean (SD) hypothermia induction time was 1.7 hour (1.5 hour), core temperature during cooling was 33.4°C (0.2), rewarming rate was 0.34°C (0.16°C) per hour and the effective cooling time was 95% (8%). Twenty-five (51%) babies had gastric bleeds, 6 (12%) had pulmonary bleeds and 21 (27%) had meconium on delivery. Fifteen (18%) babies died before discharge from hospital. Heart rate more than 120 bpm during cooling (P=0.01) and gastric bleeds (P<0.001) were associated with neonatal mortality. CONCLUSIONS The low-cost servo-controlled cooling device maintained the core temperature well within the target range. Adequately powered clinical trials are required to establish the safety and efficacy of TH in LMICs. CLINICAL TRIAL REGISTRATION NUMBER NCT01760629.

Abstract
Background Therapeutic hypothermia reduces death and disability after moderate or severe neonatal encephalopathy in high-income countries and is used as standard therapy in these settings. However, the safety and efficacy of cooling therapy in low- and middle-income countries (LMICs), where 99% of the disease burden occurs, remains unclear. We will examine whether whole body cooling reduces death or neurodisability at 18–22 months after neonatal encephalopathy, in LMICs. Methods We will randomly allocate 408 term or near-term babies (aged ≤ 6 h) with moderate or severe neonatal encephalopathy admitted to public sector neonatal units in LMIC countries (India, Bangladesh or Sri Lanka), to either usual care alone or whole-body cooling with usual care. Babies allocated to the cooling arm will have core body temperature maintained at 33.5 °C using a servo-controlled cooling device for 72 h, followed by re-warming at 0.5 °C per hour. All babies will have detailed infection screening at the time of recruitment and 3 Telsa cerebral magnetic resonance imaging and spectroscopy at 1–2 weeks after birth. Our primary endpoint is death or moderate or severe disability at the age of 18 months. Discussion Upon completion, HELIX will be the largest cooling trial in neonatal encephalopathy and will provide a definitive answer regarding the safety and efficacy of cooling therapy for neonatal encephalopathy in LMICs. The trial will also provide important data about the influence of co-existent perinatal infection on the efficacy of hypothermic neuroprotection. Trial registration ClinicalTrials.gov, NCT02387385.

Abstract
BACKGROUND Accelerated infant weight gain in individuals born full term is linked to cardiovascular risk in adulthood, but data in those born preterm are inconsistent. OBJECTIVE To investigate the association between weight gain in infancy and childhood with later markers of the metabolic syndrome in adolescents who were born preterm. STUDY DESIGN Longitudinal cohort study. SETTING Children born preterm with regular assessments of infant growth had auxology, body composition (dual X-ray absorptiometry), blood pressure, insulin sensitivity and lipid profile determined in adolescence. RESULTS We reviewed 153 children (mean gestation 30.8 weeks, median birth weight 1365 g) of whom 102 consented to venepuncture at a median age of 11.5 years. Adolescent height and weight standard deviation scores (SDS) were similar to population averages (0.01±0.92 and 0.3±1.2, respectively) and did not differ between infants when grouped according to degree of catch-up in weight gain in the immediate postdischarge period to 12 weeks of age. There were no significant associations between infant weight gain (change in weight SDS adjusted for length) and later metabolic outcome. However, there were strong associations between more rapid childhood weight gain (after 1 year of age) and subsequent body composition (higher fat mass %, fat mass index and waist circumference) and metabolic markers (higher fasting insulin, blood pressure and lower insulin sensitivity). CONCLUSIONS The association of rapid weight gain on health is time critical in those born preterm; in early infancy, this does not impact on metabolic status in adolescence, in contrast to rapid weight gain in childhood, which should be discouraged. However, given the critical importance of brain growth in the neonatal period and infancy, further research is needed before strategies that discourage infant weight gain or catch-up can be recommended for infants born preterm.

Abstract
OBJECTIVE To evaluate bronchopulmonary dysplasia (BPD), serious brain injury, and severe retinopathy of prematurity (ROP) as predictors of poor long-term outcome in very low birth weight infants. STUDY DESIGN We examined the associations between counts of the 3 morbidities and long-term outcomes in 1514 of 1791 (85%) infants with birth weights of 500-1250 g who were enrolled in the Caffeine for Apnea of Prematurity trial from October 1999, to October 2004, had complete morbidity data, and were alive at 36 weeks postmenstrual age (PMA). BPD was defined as use of supplemental oxygen at 36 weeks PMA. Serious brain injury on cranial ultrasound included grade 3 and 4 hemorrhage, cystic periventricular leucomalacia, porencephalic cysts, or ventriculomegaly of any cause. Poor long-term outcome was death after 36 weeks PMA or survival to 5 years with 1 or more of the following disabilities: motor impairment, cognitive impairment, behavior problems, poor general health, deafness, and blindness. RESULTS BPD, serious brain injury, and severe ROP occurred in 43%, 13%, and 6% of the infants, respectively. Each of the 3 morbidities was similarly and independently correlated with poor 5-year outcome. Rates of death or disability (95% CI) in children with none, any 1, any 2, and all 3 morbidities were 11.2% (9.0%-13.7%), 22.9% (19.6%-26.5%), 43.9% (35.5%-52.6%), and 61.5% (40.6%-79.8%), respectively. CONCLUSIONS In very low birth weight infants who survive to 36 weeks PMA, a count of BPD, serious brain injury, and severe ROP predicts the risk of a late death or survival with disability at 5 years.

Abstract
UNLABELLED Although brain injury after neonatal encephalopathy has been characterised well in high-income countries, little is known about such injury in low- and middle-income countries. Such injury accounts for an estimated 1 million neonatal deaths per year. We used magnetic resonance (MR) biomarkers to characterise perinatal brain injury, and examined early childhood outcomes in South India. METHODS We recruited consecutive term or near term infants with evidence of perinatal asphyxia and a Thompson encephalopathy score ≥6 within 6 h of birth, over 6 months. We performed conventional MR imaging, diffusion tensor MR imaging and thalamic proton MR spectroscopy within 3 weeks of birth. We computed group-wise differences in white matter fractional anisotropy (FA) using tract based spatial statistics. We allocated Sarnat encephalopathy stage aged 3 days, and evaluated neurodevelopmental outcomes aged 3½ years using Bayley III. RESULTS Of the 54 neonates recruited, Sarnat staging was mild in 30 (56%); moderate in 15 (28%) and severe in 6 (11%), with no encephalopathy in 3 (6%). Six infants died. Of the 48 survivors, 44 had images available for analysis. In these infants, imaging indicated perinatal rather than established antenatal origins to injury. Abnormalities were frequently observed in white matter (n = 40, 91%) and cortex (n = 31, 70%) while only 12 (27%) had abnormal basal ganglia/thalami. Reduced white matter FA was associated with Sarnat stage, deep grey nuclear injury, and MR spectroscopy N-acetylaspartate/choline, but not early Thompson scores. Outcome data were obtained in 44 infants (81%) with 38 (79%) survivors examined aged 3½ years; of these, 16 (42%) had adverse neurodevelopmental outcomes. CONCLUSIONS No infants had evidence for established brain lesions, suggesting potentially treatable perinatal origins. White matter injury was more common than deep brain nuclei injury. Our results support the need for rigorous evaluation of the efficacy of rescue hypothermic neuroprotection in low- and middle-income countries.

Abstract
INTRODUCTION Angiosarcoma of the spleen is a rare malignancy of vascular origin with a high rate of metastasis and poor prognosis. We report one such rare case of spontaneous splenic rupture, along with a review of current literature. PRESENTATION OF CASE A 30 year old man presented to our emergency services with severe abdominal pain, distension, hypotension and splenomegaly. Investigations revealed a marked anaemia, coagulopathy, severe lactic acidosis, and acute kidney injury. Imaging demonstrated splenomegaly with acute haemorrhage and lymphadenopathy. Laparotomy and splenectomy revealed piecemeal spleen and nodular omentum. The patient suffered an intra-operative cardiorespiratory arrest, and despite successful resuscitation, fatally arrested postoperatively in ICU. Histology revealed a primary splenic angiosarcoma with omental metastases. DISCUSSION Primary splenic angiosarcoma was first reported in 1879, with only 200 cases reported to date, largely as isolated case reports, with an annual incidence of 0.14-0.25 per million. With variable symptomatology and a potential to present with life-threatening complications, early diagnosis is paramount. CT scanning shows distinctive changes and is invaluable in disease assessment. Tissue diagnosis is often possible only after splenectomy. Spontaneous rupture carries the worst prognosis. CONCLUSION Primary splenic angiosarcoma is a rare and aggressive malignancy that often presents with metastatic disease, and largely carries a dismal prognosis. Definitive diagnosis is challenging, but imaging with CT scanning can show characteristic changes and establish any metastatic disease. With no established adjuvant therapy long term outlook remains poor even if treated successfully by surgery.

Abstract
Rectus capitis posterior muscles are located in the suboccipital triangle and function in extension and lateral rotation of the head and neck. There are two of these muscles on each side: the rectus capitis posterior major and the rectus capitis posterior minor. In the present case we observed bilateral double rectus capitis posterior major muscle and bilateral absence of rectus capitis posterior minor muscle. The additional rectus capitis posterior major may put more strain to the spine of the axis and mean time the bilateral absence of rectus capitis posterior minor muscles will result in muscular in coordination in the suboccipital region while balancing the head. The present variation should be considered in the aetiology of cervicogenic headache.

Abstract
BACKGROUND Although survival rates for infants of less than 26 weeks' gestation have increased, rates for those born at less than 24 weeks do not appear to have changed. While there are good data on overall survival, it is unclear how many infants are offered active resuscitation but do not survive. The study objectives were to describe the numbers receiving active treatment and the length of survival in infants live born at 22 or 23 weeks' gestation but who did not survive, and any changes over the last 15 years. METHODS The authors used a well-validated population-based database to identify deaths among live born infants born at 22 or 23 weeks' completed gestation between 1993 and 2007 from a single region in the north of England. The study period was divided into three 5-year cohorts. Survivors were identified from regional databases and individual case notes reviewed. RESULTS During the study period, there were 480 662 total live births, of which 229 were live born at 22-23 weeks' gestation (birth prevalence of 0.05%). Of the 210 infants who did not survive, 71 (34%) survived for longer than 6 h. The median survival of those who died but had received active resuscitation and were still alive at 6 h of age was 11 h in 1993-1997 (n=17), 20 h in 1998-2002 (n=28) and 3.7 days (n=26) in 2003-2007. CONCLUSION Over the last 15 years, increasing numbers of babies <24 weeks received active resuscitation. Overall survival has not changed, but non-survivors endured significantly longer durations of intensive care.

Abstract
AIM Talipes is a congenital anomaly that can be corrected conservatively or surgically. Despite advances in management, a proportion of pregnancies still result in termination. We therefore aimed to establish the birth prevalence, interventions and outcome of talipes in our population. METHODS Cases with foetal talipes were identified from the ultrasound register at the James Cook University Hospital between 1990 and 2006. Infants with congenital talipes between 1998 and 2006 were identified from the physiotherapy database. Management details were obtained from case records. RESULTS A total of 46 cases with foetal talipes were identified among 75 933 pregnancies. Of the 34 live-born infants, 24 (70.5%) required surgery to correct the talipes. Congenital talipes was found in 69 infants, giving a birth prevalence of 2 per 1000 live births. Sixteen (72.7%) infants with an antenatal diagnosis required surgical correction. Infants with an antenatal diagnosis were at an increased risk of requiring surgery (relative risk [RR]= 1.6). CONCLUSION Surgical management was required in more than two-thirds of babies with foetal talipes. Conservative management was successful in the majority of the babies without an antenatal diagnosis. Infants with an antenatal diagnosis are 1.6 times as likely to need surgical correction as infants without an antenatal diagnosis.

Abstract
OBJECTIVE The birth prevalence and malignant tumour recurrence of sacrococcygeal teratoma (SCT) have not been clearly defined. We conducted this study to determine the birth prevalence, prenatal detection rate, frequency of tumour recurrence and outcome of SCT in a population-based cohort. METHODS Cases were identified from a population-based, regional database of congenital anomalies for the years 1985-2006. Prenatal diagnosis, management details, tumour recurrence and outcome were obtained from case records and cross linked with a regional oncology database. RESULTS There were 754,172 live births and 28 live born infants with SCT giving a birth prevalence of 1 per 27 000 live births. There was a prenatal diagnosis in 50% of cases. No cases presenting in the neonatal period had malignant tumour present at diagnosis or subsequent tumour recurrence. Nine (37.5%) of the survivors had chronic morbidities. CONCLUSIONS The birth prevalence of SCT was higher than that of previously reported. Infants who were live born and survived definitive surgical management had a good prognosis.

Abstract
BACKGROUND In 1998, the senior author presented the intraoperative fluid ratio, defined as the volume of super-wet solution and intraoperative intravenous fluid divided by the aspiration volume, to guide resuscitation fluid volumes in super-wet liposuction. The senior author demonstrated that intraoperative fluid ratios of 2.1 for small-volume and 1.4 for large-volume liposuction were safe and did not cause volume overload sequelae. A high urine output was common and reflected a mild overresuscitation, which could have adverse consequences in patients with undiagnosed cardiopulmonary disease. The purpose of this study was to compare overresuscitation sequelae in a cohort of consecutive super-wet liposuction patients using a new fluid management formula in which replacement fluid was given after 5000 cc of lipoaspirate instead of 4000 cc, as initially described. METHODS The charts of 89 consecutive patients undergoing super-wet liposuction were retrospectively reviewed. RESULTS The intraoperative fluid ratio was 1.8 for the small-volume reductions (< 5000 cc, n = 68) and 1.2 (> 5001 cc, n = 21) for the large-volume reductions. There were no episodes of pulmonary edema, congestive heart failure exacerbation, or other major complications. The average urine output in the operating room, the recovery room, and while on the floor was 1.5, 1.6, and 2.9 cc/kg/hour for the small-volume group and 1.7, 1.8, and 2.5 cc/kg/hour for the large-volume group. CONCLUSIONS The super-wet subcutaneous infiltration liposuction technique for both small- and large-volume reductions is safe and can be performed without adverse cardiopulmonary sequelae. Given the high urine outputs, the intraoperative fluid ratio can be further improved by possibly eliminating the replacement fluid altogether.

Abstract
Numerous techniques have evolved in facial plastic surgery to treat rosacea and solar lentigines. The treatment regimens range from avoidance of causative factors to the use of topical agents or other modalities that target the superficial layers of the skin. Of the modalities that target the epidermis, lasers offer the physician and patient the ability to target specific chromophores in the skin. Advances in laser technology led to the implementation of targeting certain characteristic pigments of abnormal areas with minimal damage to surrounding normal tissue. Rosacea and solar lentigines have characteristic cells that are targeted by a potassium-titanyl-phosphate (KTP) laser. The lesions are different in their origins but share the ability to be treated successfully with the KTP laser. A review of both conditions and other treatment options is discussed.

Abstract
OBJECTIVE To delineate the course of serum neopterin (s-neo) concentrations in patients with pulmonary tuberculosis who are on anti-tuberculosis therapy. DESIGN S-neo concentrations were measured by high performance liquid chromatography (HPLC) in 39 patients treated for pulmonary tuberculosis at pretreatment, at one month and at end of treatment. It was also measured in 11 relapse cases and their matched controls at the above time points and at the time of relapse. The results were correlated with bacteriological and radiological findings. RESULTS All patients had elevated levels of s-neo at pretreatment which had declined at 1 month and were near normal at the end of treatment. The decline was more significant in patients with moderate lesions, suggesting that immune activation is maximum in this group of patients. The mean decrease was 37% at one month and 66% at the end of treatment. The corresponding decreases were 11% and 56% in patients with limited lesions and 11% and 45% in those with extensive lesions. It continued to fall after completion of therapy in patients who did not relapse, whereas an increase after completion of therapy was associated with bacteriologically proven relapse. CONCLUSIONS The measurement of s-neo concentration could be of help in evaluating response to therapy. This study provides a rational basis for the association between s-neo concentration and relapse.

Abstract
SETTING Cell-mediated immunity (CMI) involves macrophage activation and T cell proliferation. These two parameters are compared in this study. OBJECTIVE To ascertain the role of neopterin as a biochemical marker for CMI in patients with pulmonary tuberculosis. DESIGN We measured neopterin levels in serum and the culture supernatants of peripheral blood mononuclear cells (MNC) after stimulation with purified protein derivative (PPD) in 11 patients with pulmonary tuberculosis and 10 healthy individuals. Lymphocyte proliferative response to PPD was carried out in these two groups. RESULTS The mean concentration of serum neopterin was significantly higher in patients than in controls (P < 0.01). The spontaneous release of neopterin was significantly higher in culture supernatants of MNC from patients when compared with those of healthy controls (P < 0.05). Release of neopterin from MNC stimulated with PPD, however, was similar in both groups. The neopterin release and the stimulation index (SI) in lymphocyte proliferation assay were not comparable, suggesting that these two parameters do not run in parallel for measuring the status of CMI. However, serum concentration of neopterin was inversely related to the SI in a large proportion of subjects (66%). CONCLUSION Measurement of neopterin, a soluble product of immune cells (macrophage), may provide information on the state of CMI.

Abstract
Monocytes from purified protein derivative S Mantoux-negative children and young adults inhibited intracellular growth of Mycobacterium microti more in Chingleput than in London. Mycobacterium bovis BCG vaccination did not enhance bacteriostasis with the Indians but did so with the Londoners. No evidence was found for involvement of cytokines such as macrophage-activating factor and granulocyte macrophage colony-stimulating factor in the differences.
