A standardised protocol for the acute management of corrosive ingestion in children

Laparoscopic transhiatal esophago-gastrectomy after corrosive injury

Esophago-gastric necrosis is a surgical emergency associated with high morbidity and mortality. We report a laparoscopic transhiatal esophago-gastrectomy performed on a 43-year-old male, presenting two hours after hydrochloric acid ingestion. A gastroscopy showed several oral mucosal ulcers, a significant edema of the pharynx and larynx, a necrosis of the middle and lower esophagus and of the gastric fundus and antrum. A conservative strategy with intensive care observation was initially followed. After a change of clinical signs, chest-abdominal computed tomography was realized and a pneumoperitoneum with free fluid in the left subphrenic space and bilateral pleural effusions was in evidence. A laparoscopic exploration was proposed to the patient, and confirmed the presence of free peritoneal fluid and necrosis with perforation of the upper part of the stomach. A laparoscopic total gastrectomy with subtotal esophagectomy was performed; the procedure finished with an esophagostomy on the left side of the neck and a laparoscopic feeding jejunostomy (video). Total operative time was 235 minutes. After six months a digestive reconstruction with esophagocoloplasty by laparotomy and cervicotomy was easily realized thanks to the advantages (few adhesions, bloodless, and simple colic mobilization) of the previous minimally invasive surgery.

Continuous infusion of methylprednisolone via paediatric parenteral nutrition: A pharmacokinetic animal study

BACKGROUND & AIMS

The aim of our study consisted to measure the pharmacokinetic parameters of methylprednisolone administered in a continuous infusion of a paediatric parenteral nutrition mixture for 24h in the rabbit.

METHODS

Fourteen rabbits were split into two groups and assigned a different administration vehicle (all-in-one or two-in-one nutrition mixture). We used USC PACK* pharmacokinetics software to compare the influence of the composition of the paediatric parenteral nutritional solutions on the values of the pharmacokinetic parameters of methylprednisolone.

RESULTS

Neither the steady-state plasma concentrations of methylprednisolone hemisuccinate nor the values of the pharmacokinetic parameters of methylprednisolone differed significantly when administered in two-in-one or all-in-one nutrition mixtures.

CONCLUSIONS

The composition of the nutritional medium had no discernable effect on the bioavailability of methylprednisolone. Neither the speed at which the steady-state plasma concentration was reached, nor the values of the pharmacokinetic parameters of methylprednisolone were significantly modified.

Updates on the Evaluation and Management of Caustic Exposures

In 2004, the American Association of Poison Control Centers' Toxic Exposure Surveillance System documented over 200,000 exposures to caustic substances, in both household and industrial products. Although the most commonly affected body areas are the face, eyes, and extremities, all reported fatalities were as a result of ingestion. Little controversy exists in patient management following dermal or ocular caustic exposure. Immediate water irrigation of the site of caustic exposure, followed by routine burn care, analgesia, intravenous fluids, and electrolyte replacement are standards of care. In this manuscript, a thorough review of the management of gastrointestinal caustic exposure is explored, not only because of the high rates of morbidity and mortality associated with these exposures, but also because there remains controversy regarding appropriate management of such exposures. Hydrofluoric acid, a weak acid in its aqueous form, requires special consideration and specific antidotes, and as such, is addressed separately.

Increasing tendency in caustic esophageal burns and long-term polytetrafluorethylene stenting in severe cases: 10 years experience

In recent years, lye products have come into common household use in Turkey. Unfortunately, we have noted more cases of serious corrosive esophagitis owing to accidental caustic agent ingestion. The aims of this study were to (1) evaluate our experience with these cases and (2) investigate the effects of long-term intraesophageal polytetrafluorethylene stenting on esophageal remodeling and its impact upon the need for esophageal replacement. Between 1997 and 2006, 68 patients (44 males and 22 females) with accidental caustic agent ingestion were admitted to our department, the only tertiary care referral center for the Turkish Army. Once stabilized, esophagoscopy was performed for injury grading (grades 0, 1, 2a, 3b, 3a, or 3b) as described by Millar and Cywes (Pediatric Surgery. 1998;969-979). Esophagogram was performed 3 weeks after injury to assess healing. At presentation, the injury grade for 24, 31, 11, and 1 cases were 0 or 1, 2a, 2b, and 3a, respectively. One case had gastric outlet obstruction. All cases of grade 0 or 1 injuries had a normal esophagogram at 3 weeks postinjury. For the remaining 44 patients, several treatment modalities have been applied, including antegrade and retrograde dilatations in 31 grade 2a patients, intraluminal stenting in 11 grade 2b patients, esophageal reconstruction in 1 grade 3a patient, and gastroenterostomy in 1. Of the 11 patients with esophageal stenting, 8 patients have resumed a normal diet after 9 to 14 months of stenting. Mean follow up duration is 3.5 years (1-6 years) after stent removal. In the remaining 3 cases, treatment is still ongoing. Esophagitis and esophageal structuring because of caustic agent ingestion is a major public health problem in Turkey. Our small uncontrolled pilot series suggests that intraluminal polytetrafluorethylene stenting may be an effective treatment method to reduce the need for major surgical reconstruction of recalcitrant esophageal strictures.

Suspected clindamycin-associated oesophageal injury in cats: five cases

The clinical findings, treatment and outcome of suspected clindamycin-associated oesophageal injury in five cats are reported. All cats were treated with one 75 mg clindamycin capsule twice daily (dose range 12-19 mg/kg). Capsules were administered without food or a water bolus. Dysphagia, regurgitation, choking or gagging were seen 3-9 days after starting clindamycin. On oesophagoscopy, three cats had oesophagitis, one of which progressed to stricture formation. Two cats had an oesophageal stricture at first presentation. This is the first report of suspected clindamycin-associated oesophageal injury in cats. It serves to further alert practitioners to the potential for drug-induced oesophageal disorders (DIOD) in cats treated with oral medications and to urge prevention by promoting a change in dosing practices.

A different aspect of corrosive ingestion in children: socio-demographic characteristics and effect of family functioning

OBJECTIVE

Corrosive ingestion is thoroughly investigated in terms of its complications and treatment modalities but to date family functioning, behavior, attitude and knowledge of mothers of children who ingested corrosives has not been investigated and socio-demographic data has rarely been mentioned. Therefore a study was planned to investigate the socio-demographic data, family functioning, knowledge, behavior and attitude of mothers of children who ingested corrosive materials.

METHODS

The mothers of 50 children who ingested corrosive materials and 60 controls were asked to answer a questionnaire which included socio-demographic data and questions about their attitude, behavior and knowledge of corrosive ingestion. The mothers were also asked to reply family assessment device (FAD) and parental attitude research instrument (PARI).

RESULTS

The average ages of the children were 5.31+/-2.32 in the corrosive group with an M:F ratio of 1:1. The level of education of both mothers (p=0.000) and fathers (p=0.000) in the corrosive group were lower than that of the controls. There was no difference between the two groups in terms of number of working mothers (p=0.085). In the corrosive group the families used to have three or more children (42%) and the socioeconomic status of this group was lower than the controls (p=0.001). In the corrosive group these substances were purchased unlabeled (64%) and kept mainly in coke bottles. The affective involvement dimension of the FAD and the attitude of over-parenting and democratic attitude dimensions of the PARI tests were significantly different in the corrosive group among mothers from lower educational level whereas no difference was detected among mothers from higher educational level in this regard.

CONCLUSION

It was found that both level of education of the parents and socioeconomic factors played important role in shaping the habits that might lead to corrosive ingestion in children. For the prevention of corrosive ingestion broad based strategies including education are required.
