Paediatric trainees and the transportation of critically ill neonates: experience, training and confidence

AIM: To study the experience of, training in, and confidence in the transportation of critically ill neonates amongst paediatric trainees in one UK region. DESIGN: An anonymized questionnaire was sent to all middle grades with paediatrics National Training Numbers from the Trent region. RESULTS: The response rate was 78%. Less than half (45%) of the respondents reported receiving any training in the transportation of neonates, either in the UK or abroad; 45% (30/66) of the trainees reported having performed 10 or fewer neonatal transfers. The self-perceived confidence for transporting neonates was scored on a 10-point scale, to produce a "confidence score", the median score being 7 (IQ range 5, 8). Both as a group and individually, the trainee paediatricians were more confident in transporting neonates than older infants or children (p < 0.0001). Using multiple analysis of covariance, it was found that the most important and significant variables affecting the "confidence scores" for the inter-hospital transportation of critically ill neonates were receipt of any relevant transport training, and the current frequency of transports performed. CONCLUSIONS: Many training-grade paediatricians lack both the experience and training in transporting critically ill neonates, factors that were found to affect their confidence in transferring sick neonates. As the overwhelming majority of neonatal transports in the UK are still arranged by individual units and performed by training-grade paediatricians, concerns regarding both the safety and effectiveness of the current service provision for the inter-hospital transfer of critically ill neonates remain valid.     

Ventral hernia repair: a study of current practice

Ventral wall hernias are common; despite this, there are no guidelines on the best surgical management. The aim of this study was to examine the types of repair in use for abdominal wall hernias in the West of Scotland over a 3-month period. Data were gathered on 120 patients. There were 60 incisional, 32 umbilical, and 28 epigastric hernias. The main indication for repair was pain (78%), while 12 patients (10%), presented acutely with incarceration or strangulation. The most common method of repair was sutured (55%), followed by mesh (29%) and Mayo repair (16%). There was no correlation between use of mesh and hernia size or whether repair was for a recurrent hernia. Surgical practice varies widely in the repair of ventral wall hernias. Clinical trials are required to establish the best method of repair for this common condition. Electronic Publication     

D2 lymphadenectomy in the management of gastric cancer

Background Gastric carcinoma is a significant cause of death in Ireland. Surgery offers the best option of cure, but the five-year survival following resection remains dismal at 10–15%. Experience from Japan and from some Western units suggest that an extended (D2) lymphadenectomy in association with gastrectomy increases the prospect of cure, but concern about the morbidity and mortality of this operation and lack of evidence from randomised studies has limited its acceptance. Aims This study reports the experience of a specialist upper gastrointestinal unit with D2 gastrectomy in a four-year audit. Methods Sixty-two resections were performed for gastric cancer. Results Nineteen patients were deemed unsuitable for the D2 procedure and underwent a more limited lymphadenectomy (DO or D1). Forty-three patients underwent D2 resection, 12 with an oesophagogastrectomy, 22 with total gastrectomy and nine with a sub-total distal resection. Eight patients undergoing D2 resection had extended resections, five with splenectomy and three with a distal pancreatectomy. Post-operative complications occurred in 31% of patients. Thirty-day and 90-day mortality were zero. Median survival was 822 days in the D2 group (range 120–1,320). Conclusions These results show that a D2 gastrectomy can be performed with a low morbidity and mortality and a median survival of greater than two years.     

Effect of tumour and chemoradiotherapy on oesophageal motility

Background The contribution of dysmotility to dysphagia in oesophageal cancer is unclear. Aim To examine oesophageal motility in patients with oesophageal carcinoma and to assess the effect of chemoradiotherapy on motility. Methods Stationary manometry and 24-hour pH-metry were performed in 12 patients with oesophageal carcinoma and one week following completion of chemoradiotherapy using 5-fluorouracil (5-FU), cisplatin and 40Gy radiotherapy. Results All patients had abnormal motility prior to treatment. Peristalsis was impaired in 11 patients with a mean (SD) of 25% (9) of waves normally propagated. Eight patients had 20% or more simultaneous waves. Following chemoradiotherapy, the percentage of waves normally propagated increased from 25% (9) to 52% (10) (p < 0.03) and normal peristalsis was restored in four patients. The percentage of simultaneous waves decreased from 38% (11) to 21.6% (10) (p=0.129) while the percentage of dropped or increased waves decreased from 20% (11) to 8.3% (4) (p=0.264). Conclusions Oesophageal motility is disturbed in oesophageal cancer. Dysphagia in oesophageal cancer may be partly explained by oesophageal dysmotility. This is improved by chemotherapy.     

Impact of the fungicide carbendazim in freshwater microcosms. I. Water quality, breakdown of particulate organic matter and responses of macroinvertebrates

Effects of chronic application of the fungicide Derosal(R) (active ingredient carbendazim) were studied in indoor macrophyte-dominated freshwater microcosms. The concentrations (0, 3.3, 33, 100, 330 and 1000 μg/l) were kept at a constant level for 4 weeks. This paper is the first of a series of two, and describes the fate of carbendazim and its effects on water quality parameters, breakdown of POM, and responses of macroinvertebrates. Carbendazim proved very persistent in the water layer. Values for t(12) varied between 6 and 25 weeks, and decreased with the treatment level. Significant effects on water quality parameters (DO, pH, alkalinity, conductivity) could not be demonstrated. After 4 weeks of incubation, the breakdown of Populus leaves was significantly slower at the two highest carbendazim concentrations. The macroinvertebrate community was seriously affected by carbendazim application, with Oligochaeta, Turbellaria, Hirudinea and some Crustacea as the most sensitive groups. The snail Bithynia decreased in numbers, but other gastropods increased in numbers. Safety factors as proposed by the Uniform Principles (European Union) for the risk assessment of pesticides, to be multiplied with toxicity data of the standard test species (Daphnia, fish, algae), appeared to ensure adequate protection of sensitive populations present in the microcosms.     

Neuropsychiatric side-effects of lidocaine: examples from the treatment of headache and a review

Lidocaine has been used in treatment of patients with refractory headache. Personal observations of neuropsychiatric toxicity in these patients led us to review our cases and the literature systematically for lidocaine side-effects, especially neuropsychiatric symptoms. In our series of 20 patients, side-effects were observed in all, the most frequent being neuropsychiatric (75%) and cardiological (50%). When reviewing published series on intravenous lidocaine use, reports of side-effects range from 0 to 100%, with neuropsychiatric symptoms being reported in 1.8–100%. Thirty-six case reports of lidocaine-induced psychiatric symptoms were also analysed. Psychiatric symptoms of toxicity were similar in most patients, despite their differing ages, pathologies, co-therapies and lidocaine dosages. In conclusion, lidocaine neuropsychiatric toxicity has a well-recognized stereotypical clinical presentation that is probably unrecognized in headache series. As lidocaine represents an emerging alternative therapy in headache, particularly in short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing, clinicians and patients should be aware of the extent of this problem.

Vasodilator agents and supracollicular transection fail to inhibit cortical spreading depression in the cat

It remains an open question as to whether cortical spreading depression (CSD) is the pathophysiological correlate of the neurological symptoms in migraine with aura. In the experimental animal, CSD is an electrophysiological phenomenon mainly mediated via NMDA receptors. However, according to case reports in humans, visual aura in migraine can be alleviated by vasodilator substances, such as amyl nitrite and isoprenaline. There is also circumstantial evidence that brainstem nuclei (dorsal raphe nucleus and locus coeruleus) may play a pivotal role in the initiation of aura. In this study, CSD was elicited in alpha-chloralose anesthetized cats by cortical needle stab injury and monitored by means of laser Doppler flowmetry. Topical application of isoprenaline (0.1-1%) and amyl nitrite (0.05%) onto the exposed cortex had no effect on the elicitation or propagation of CSD. Also, after supracollicular transection, subsequent CSDs showed no differences in the speed of propagation and associated flow changes. We conclude from these data that--given CSD probably exists in humans during migraine--spreading neurological deficits during migraine aura are independent of brainstem influence and have a primarily neuronal rather than vascular mechanism of generation.
