A rare occurrence of multiple intestinal atresias, with successful one-procedure resection and primary anastomosis.

SUMMARY: Intestinal atresia is a common cause of neonatal bowel obstruction. Many theories exist relating to intestinal atresia, though the best explanation is related to vascular events. Duodenal atresia is thought to be due to a developmental anomaly of the intestine. A rare combination of concomitant Type III duodenal atresia, Type III B jejunal atresia, and Type I ileal atresia is presented. The differing pathogenesis of these atresias makes the condition exceptionally rare. This patient was successfully treated, via explorative laparotomy, with resection of the atretic segments and two primary anastomoses, without the need for enterostomies or stents.

Solid malignancies during the first year of life: A 20-year review at Red Cross War Memorial Children's Hospital, Cape Town, South Africa.

BACKGROUND: Among paediatric tumours, two groups stand out: neonatal and infantile tumours, which respectively represent 2% and 10% of paediatric tumours. The distribution of tumours in these age groups is different from that in older children. Objectives. Descriptive analysis of a cohort of patients treated for a solid malignancy at Red Cross War Memorial Children's Hospital (RCWMCH), Cape Town, South Africa. Methods. A 20-year retrospective case series review of patients aged <1 year at diagnosis was performed on data extracted from the RCWMCH oncology database. Results. Of 243 cases extracted from the database, 198 were solid tumours, of which 122 (61.1%) were included in the analysis; the 76 excluded were benign or of eye, bone or central nervous system origin and therefore did not meet the inclusion criteria. There were 38 renal malignancies (31.2%), 30 neuroblastomas (24.6%), 25 soft-tissue sarcomas (20.5%), 17 germ cell tumours/gonadal tumours (13.9%) and 12 liver tumours (9.8%). Of the patients, 119 (97.5%) had surgery, 91 (74.6%) had chemotherapy and 10 (8.2%) had radiotherapy. Tumour group 5-year survival was 78.5% for neuroblastic tumours, 79.0% for nephroblastomas, 81.5% for hepatoblastomas, 62.5% and 54.2% for rhabdomyosarcoma and non-rhabdomyosarcoma soft-tissue sarcomas, respectively, and 79.5% for malignant extracranial and extragonadal germ cell tumours. For the entire cohort, the mean follow-up was 46 months, with an estimated 5-year overall survival of 74.6%. Mortality was 21.5% and loss to follow-up 6.6%. Conclusion. The distribution of tumours differs slightly from the literature, with a predominance of renal tumours over neuroblastomas. The overall mortality rate of 21.5%, the surgical complication rate of 10.9% and the 5-year overall survival of 74.6% correspond with the literature, supporting the view that a paediatric hospital in a middle-income country can achieve results similar to those in higher-income countries when international protocols are applied by a dedicated multidisciplinary team.

Measurements in wound healing with observations on the effects of topical agents on full thickness dermal incised wounds.

INTRODUCTION: A multitude of topical wound treatments are used today. Although it is well established that the micro-environment of healing wounds can be altered to improve healing, it is difficult to measure the subtle differences in outcome where therapies are compared. METHOD: We compared wound healing properties between four different topical agents in surgically incised wounds in a pig model. The four topical agents, 5% Povidone-Iodine cream, 1% Silver-Sulphadiazine, 2% Mupirocin, and 1% Silver-Sulphadiazine plus 1mg/100g recombinant-human epithelial growth factor (EGF) were randomly assigned to four test animals each. Test agents were compared to each other and to untreated controls. We investigated existing and new methodologies of measurement of wound healing: clinical and histological visual scoring systems, immuno-histochemistry, and computerized image analysis of the wounds on days 3, 7, and 28. RESULTS: All agents were found to have improved healing rates with better cellular architecture. Healing was faster, histological appearance resembled normal architecture sooner, clinical appearance improved, mitotic activity was stimulated and more collagen was deposited in comparison to the wounds with no agents. EGF-treated wounds showed an increased rate of epithelisation, but the rate of healing did not correlate well with evaluation of cosmetic outcome. CONCLUSION: Topical agents improve all aspects of wound healing. The addition of a human recombinant EGF to Silver-Sulphadiazine increases epithelial growth and amounts of collagen in the regenerating wounds at day 7.

Local anesthetic wound infusion versus standard analgesia in paediatric post-operative pain control.

INTRODUCTION: Local anesthetic wound infusion has shown promising results in adults. Its use in children is limited to some centers and there are only a few prospective trials in this group of patients. METHODS: Sub-fascial continuous local anaesthetic wound infusion (CLAWI) (0.2% Bupivacaine) plus intravenous paracetamol and rescue intravenous morphine was compared to: (a) Epidural bupivacaine (EPI) plus paracetamol and rescue intravenous morphine for patients undergoing laparotomy. (b) Intravenous morphine and paracetamol (standard post-operative analgesia-SAPA) in children undergoing Lanz incision laparotomy for complicated appendicitis. 'InfiltralLong', PANJUNK(®) catheters were placed sub-fascially after peritoneal closure for post-operative bupivacaine infusion. Pain scores were recorded regularly by the same blinded pain specialist. The primary outcomes were pain control and total morphine. The secondary outcomes were time to full feeds, mobilization requirement for urinary catheter and complications. RESULTS: Sixty patients (18 laparotomy-CLAWI, 17 laparotomy-EPI and 12 appendectomy-CLAWI, and 13 appendectomy-SAPA) were analyzed. The average pain score was 2.5 (1-4) in the CLAWI groups, 3.0 (1-5) in the EPI group and 3.5 (2-5) in the SAPA group. Morphine requirements were markedly less for CLAWI. SAPA and EPI groups required urinary catheters for longer and took longer to mobilize (average 4 days compared to 2 days for CLAWI). There were no wound or bupivacaine complications in the CLAWI group. CONCLUSION: Continuous subfascial bupivacaine infusion is reliable, safe and effective in paediatric post-operative pain control with considerably reduced opiate requirements.

A review of community management of paediatric burns.

This study was a component of a broader review to evaluate burn care in South Africa. A prospective audit of 353 children with thermal injuries admitted to the Red Cross War Memorial Children's Hospital in Cape Town was performed during 2012/2013. The audit was based to assess the adherence of initial burn management to the provincial policy guidelines on the clinical management of the burn wound. The community management of each patient prior to admission to a burns centre was assessed for the following: basic demographics, emergency home management, wound cover, analgesia and transport to medical facilities. Their ages ranged from 1 month to 14 years. The average total body surface area [TBSA] was 15% [1-86%]. Most of the injuries were due to hot water accidents [78.5%] followed by flame burns (9%), direct contact and electricity burns. Two hundred and twenty five children [63%] received first aid measures at home, including cooling with water [166] ice [30] and a cooling agent. No cooling was instituted in 130 and 65% of the patient's wounds were cooled for 10 min or less. Eighty percent proceeded to the referral centre or burns unit without their wounds being covered; with only 19 patients having any medical type of dressing available at home. Two hundred and ninety five children [83.6%] received pain medication prior to admission at the burns unit. Of the 316 patients not directly attending the burns unit, 137 received i.v. fluids of which 95 had burns greater than 10% TBSA. None of the patients were in shock on admission and all i.v. lines were functioning. Forty-four children with burns greater than 10% did not receive i.v. fluids. The audit identified six factors that were inadequately addressed during the pre-admission period: first aid, cooling of the wound, early covering of the wound, resuscitation, pain management and transfer. If these could be readdressed, basic burn care would be substantially improved in the study area.

Burn care in South Africa: a micro cosmos of Africa.

Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

Burn resuscitation on the African continent.

A survey of members of the International Society of Burn Injuries (ISBI) and the American Burn Association (ABA) indicated that although there was difference in burn resuscitation protocols, they all fulfilled their functions. This study presents the findings of the same survey replicated in Africa, the only continent not included in the original survey. One hundred and eight responses were received. The mean annual number of admissions per unit was ninety-eight. Fluid resuscitation was usually initiated with total body surface area burns of either more than ten or more than fifteen percent. Twenty-six respondents made use of enteral resuscitation. The preferred resuscitation formula was the Parkland formula, and Ringer's Lactate was the favoured intravenous fluid. Despite satisfaction with the formula, many respondents believed that patients received volumes that differed from that predicted. Urine output was the principle guide to adequate resuscitation, with only twenty-one using the evolving clinical picture and thirty using invasive monitoring methods. Only fifty-one respondents replied to the question relating to the method of adjusting resuscitation. While colloids are not available in many parts of the African continent on account of cost, one might infer than African burn surgeons make better use of enteral resuscitation.

Thermal injury within the first 4 months of life.

AIM: To determine the incidence, magnitude of injury, fluid management, role of surgery and outcome in newborns and infants under 4 months of age admitted to a Burns Unit. METHOD: Retrospective analysis of patient records. RESULTS: 86 patients under the age of 4 months were admitted over a 37 year period (0.34% of admissions). Their injuries were caused by hot water in 45 and fire in 38, primitive heating devices in 2 and non-accidental paraffin burn in 1. Twenty-eight sustained superficial partial thickness burns, 12 deep partial thickness and 46 full thickness injuries. The total body surface area ranged from 1 to 55% with an average of 11.5%. Bacterial contamination of the burn wounds was present on admission in 52.3% and consisted of both gram positive and gram negative organisms. The resuscitation formula of 3.5 ml/kg/% burn on the first day and 1.5 ml/kg/% burn on the second day plus maintenance fluid at 30-120 ml/kg/day was not always adequate in maintaining haemodynamic stability. Three surgical methods were employed in 59 patients (69%). These included early tangential excision in 25, excision with or without allograft and delayed grafting in 27, and conventional therapy with eventual grafting in 7 patients. Releasing escharotomies were required in 9 children. Nineteen children required amputations. Three craniectomies, 2 tracheostomies and 1 colostomy were additional procedures. The mortality was 9.3%. Three causes of death were identified: magnitude of injury, sepsis and inhalation injury. CONCLUSION: Neonates and infants are very vulnerable and preventable environmental factors are often implicated. Fire and hot water are the most common causes resulting in significant physical trauma. Resuscitation especially during the first few days of life can be problematic. Wound infection and sepsis are common and surgery should be individualised. Long-term outcome is very satisfactory for those with small burns however those with larger burns may remain permanently disfigured.

Treatment of paediatric burns with a nanocrystalline silver dressing compared with standard wound care in a burns unit: a cost analysis.

Burns are a leading cause of non-natural death in South African infants and children. Conventional care of partial-thickness burns often requires painful, time consuming and costly twice-daily dressing changes to clean the wound and apply antimicrobial topical agents. A new topical nanocrystalline silver-coated NS dressing (Acticoat; Smith & Nephew) has been developed and is the first-line treatment of choice in many burn centres. However, because of its cost the Department of Health has been reluctant to introduce it as a standard of care. We retrospectively studied 4 randomly selected paediatric burn patients, calculating the cost associated with the use of NS dressings and comparing this with the projected costs of three previously standard burn wound treatment regimens. NS dressings were changed every 3 days based on their sustained and slow release of silver ions over 72 hours. Using NS clearly saved costs compared with the three other regimens. The demonstrated cost savings resulted primarily from the decreased number of dressings, and the presumed shorter hospital stay.

Colonic atresia: spectrum of presentation and pitfalls in management. A review of 14 cases.

Fourteen cases of colonic atresia seen over a 38-year period are reviewed with particular reference to clinical presentation and pitfalls in management. Seven had Type I atresia, two Type II and five Type IIIa. Ten had associated gastrointestinal anomalies. Management varied considerably. Six had primary colonic anastomosis. Two of these developed complications due to unrecognized distal hypoganglionosis, two had associated jejunal atresias resulting in short bowel syndrome, and two had primary anastomosis protected by proximal ileostomies. Seven had a staged repair with initial defunctioning enterostomy with only one complication, an unfixed mesentery that later resulted in midgut volvulus. The only mortality was a patient in which a jejunal atresia repair leaked as a result of a missed colonic atresia. Operative strategy should depend on the clinical state of the patients, the level of atresia, associated small bowel pathology and exclusion of distal pathology. Primary anastomosis would only rarely be advised with a circumspect approach. Long-term outlook, as in small bowel atresia is generally excellent.

Ultrasonography for ilioinguinal/iliohypogastric nerve blocks in children.

BACKGROUND: The ilioinguinal/iliohypogastric nerve block is a popular regional anaesthetic technique for children undergoing inguinal surgery. The success rate is only 70-80% and complications may occur. A prospective randomized double-blinded study was designed to compare the use of ultrasonography with the conventional ilioinguinal/iliohypogastric nerve block technique. METHODS: One hundred children (age range, 1 month-8 years) scheduled for inguinal hernia repair, orchidopexy or hydrocele repair were included in the study. Following induction of general anaesthesia, the children received an ilioinguinal/iliohypogastric block performed either under ultrasound guidance using levobupivacaine 0.25% until both nerves were surrounded by the local anaesthetic or by the conventional 'fascial click' method using levobupivacaine 0.25% (0.3 ml kg(-1)). Additional intra- and postoperative analgesic requirements were recorded. RESULTS: Ultrasonographic visualization of the ilioinguinal/iliohypogastric nerves was possible in all cases. The amount of local anaesthetic used in the ultrasound group was significantly lower than in the 'fascial click' group (0.19 (SD 0.05) ml kg(-1) vs 0.3 ml kg(-1), P<0.0001). During the intraoperative period 4% of the children in the ultrasound group received additional analgesics compared with 26% in the fascial click group (P=0.004). Only three children (6%) in the ultrasound-guided group needed postoperative rectal acetaminophen compared with 20 children (40%) in the fascial click group (P<0.0001). CONCLUSIONS: Ultrasound-guided ilioinguinal/iliohypogastric nerve blocks can be achieved with significantly smaller volumes of local anaesthetics. The intra- and postoperative requirements for additional analgesia are significantly lower than with the conventional method.

Dysphoria: self-devaluative and affective components in recovered depressed patients and never depressed controls.

BACKGROUND: The Interacting Cognitive Subsystems analysis of cognitive vulnerability to depression predicts that subjective experiences of dysphoria in recovered depressed patients will be qualitatively different from those of controls. This study tested this prediction using a new instrument, the Depressed States Checklist. METHODS: Twenty-three recovered recurrently depressed patients and 54 never depressed controls rated the affective and self-devaluative components of a dysphoric experience. RESULTS: Groups reported similar levels of affective component but recovered depressed patients reported higher self-devaluative dysphoric experience. At zero affective component of dysphoria neither group reported any self-devaluative feelings. With increasing affective component of dysphoria, the self-devaluative component increased significantly more in recovered patients than in controls. The ratio of self-devaluative to affective components of dysphoria significantly differentiated recovered depressed patients from controls. CONCLUSIONS: As predicted, dysphoria in recovered depressed patients is qualitatively different from controls in ways that increase vulnerability to major depression. The Depressed States Checklist is a new, brief, measure of cognitive vulnerability to depression that may be particularly useful in large, prospective, epidemiological studies.

Breastfeeding--a gradual return to mother's autonomy.

The aim of this study, the final in a series, was to assess mothers' perceptions of some aspects of midwifery care in relation to breastfeeding. These included conflicting advice and its possible effect on breastfeeding outcomes; whether information considered crucial to the maintenance of breastfeeding was provided by health professionals; and whether mother's autonomy was encouraged following the implementation of antenatal breastfeeding workshops. A structured, self-administered questionnaire was mailed to 550 women who delivered in 1994 approximately one year after the birth of their child. The results obtained were compared to those achieved in a 1991 survey of a similar population. Of the 247 respondents, 33.5% considered they had received conflicting advice, with 18.6% commenting they felt this had negatively influenced how successfully they had breastfed. Three quarters of the women surveyed indicated they received information on the factors considered crucial for the maintenance of lactation. Seventy-eight percent (78%) said they usually or always attached the baby for themselves. Fifty-three percent (53%) of the mothers breastfed for more than six months, and 37.7% were still breastfeeding at 12 months.

Functional MRI study of the cognitive generation of affect.

OBJECTIVE: The authors investigated, by whole brain functional magnetic resonance imaging (MRI), the neural substrate underlying processing of emotion-related meanings. METHOD: Six healthy subjects underwent functional MRI while viewing 1) alternating blocks of pairs of pictures and captions evoking negative feelings and the same materials irrelevantly paired to produce less emotion (reference pairs); 2) alternating blocks of picture-caption pairs evoking positive feelings and the same materials irrelevantly paired to produce less emotion; and 3) alternating blocks of picture-caption pairs evoking positive feelings and picture-caption pairs evoking negative feelings. RESULTS: Compared with the reference picture-caption pairs, negative pairs activated the right medial and middle frontal gyri, right anterior cingulate gyrus, and right thalamus. Compared with the reference picture-caption pairs, positive pairs activated the right and left insula, right inferior frontal gyrus, left splenium, and left precuneus. Compared with the negative picture-caption pairs, positive pairs activated the right and left medial frontal gyri, right anterior cingulate gyrus, right precentral gyrus, and left caudate. CONCLUSIONS: Contrasts of both 1) negative and reference picture-caption pairs and 2) positive and negative picture-caption pairs activated networks involving similar areas in the medial frontal gyrus (Brodmann's area 9) and right anterior cingu-late gyrus (areas 24 and 32). The area 9 sites activated are strikingly similar to sites activated in related positron emission tomography experiments. Activation of these same sites by a range of evoked affects, elicited by different methods, is consistent with areas within the medial prefrontal cortex mediating the processing of affect-related meanings, a process common to many forms of emotion production.

Developing effective interactions to improve breastfeeding outcomes.

The objective of this replicated research was to assess the effectiveness of antenatal Breastfeeding Workshops (Jamieson 1990) in improving breastfeeding outcomes. It was a longitudinal study using a pre-test/post-test design to evaluate any increase in the confidence, skill and knowledge of women and midwives. The research was carried out in the maternity section of a large Tasmanian teaching hospital. Fifty-six midwives who attended the workshops became the research group with 49 non-attendees as the control. Of the 159 women who indicated an interest in attending, 107 who attended formed the research group, and the remaining 52 were used as the control. The paper is in two parts. The first describes responses from midwives. The results show those midwives who attended a workshop perceived an increase in their confidence level in supporting mothers to breastfeed, altered their perception of those factors most important in successful breastfeeding, and acknowledged that updating of breastfeeding knowledge is necessary on an annual basis. The second part analyses breastfeeding outcomes in respondent women. The results show that women who attended the workshops had a significant increase in confidence levels associated with breastfeeding, and were more likely (p < 0.01) to breastfeed for an extended time even though they experienced difficulties.

Workplace health education: results from a national survey.

A national survey of individuals responsible for workplace health education was conducted by self-administered mailed questionnaire. The present analysis examines the responses to the questions on the types of health education activities undertaken and the prior training in health education of those responsible for this work. Results suggest that interest and activity in workplace health education is increasing but that there is a serious lack of training in health education on the parts of those responsible for this work.
