The purpose of this paper is to study the use of upper gastrointestinal (Gl) fiberoptic endoscopy in children. Two hundred consecutive patients referred to one of the authors were reviewed. The indications for performing upper gastrointestinal endoscopy in these 200 patients were: (1) recurrent abdominal pain (46.5%), (2) persistent vomiting (14.5%), (3) haematemesis (14.5%), (4) acute abdominal pain (13%) and (5) other indications such as foreign body removal, failure to thrive and unexplained chest pain (11.5%). The endoscopy was performed with the Olympus P3 or Olympus XP-10 gastroscopes. The sedation used was a combination of intravenous pethidine (2mg/kg) and diazepam (0.5 mg/kg). Among the patients with recurrent abdominal pain, upper Gl endoscopy showed duodenal ulcer in 7 patients (7.5%), duodenitis in 4 (4.3%), oesophagitis in 4 (4.3%) and gastric ulcer in 2 (2.2%). The rest of the patients were normal (81.7%). With regard to persistent vomiting, 37.9% of the patients showed gastroesophageal reflux and 6.9% had a hiatus hernia. Of 29 patients examined endoscopically for upper Gl bleeding, no focus of bleeding was identified in 27.6%. The remaining 72.4% were bleeding from acute gastric erosion (27.6%), oesophagitis (17.2%), oesophageal varices (13.8%), duodenal ulcer (10.3%) and Mallory-Weiss tear (3.5%). The Majority of the patients with acute abdominal pain were normal endoscopically (61.5%). The two common abnormal findings were acute gastritis (27.0%) and acute duodenitis (11.5%). No major complications were encountered during the procedure in these 200 patients. It was concluded that upper Gl endoscopy is useful for defining upper Gl mucosal pathology. The procedure can be performed safely in children under sedation.

In clinical diagnosis, a patient's symptoms are observed and the probabilities of various diseases are assessed. A widely used method of formalizing this approach is independent Bayes in which symptoms are assumed to be independent conditional on the disease category. Correspondence analysis provides a method for examining the dependence between symptoms and assists in the selection of a reduced set of symptoms for the application of the independent Bayes method. This approach is illustrated on two data sets concerned with patients attending Accident and Emergency departments with chest pain and acute abdominal pain, respectively.

An acute abdominal pain program run on a microcomputer is described and the experiences tabulated for a series of 194 patients seen in a general hospital setting. The initial diagnostic accuracy of the program compared favorably with that of attending physicians and house staff, and suggests that improvements in the program can lead to a more effective and more accurate abdominal pain program. The possibilities for developing other programs, particularly chest pain, fever, and other global categories, are obvious. We are presently working on a chest pain program and a diagnostic strategy program. Based on the results reported here, we believe that several factors could improve program accuracy. For example, with additional clinical studies and refinement of the program structure, with more expert knowledge, and with further algorithmic development, the program could be made to outperform the average clinician and possibly approach the level of true clinical experts in abdominal pain diagnosis by mimicking their analysis. Indeed, since a program of this type is capable of incorporating the expertise of many different clinicians, it has the potential of outperforming any given expert in specific cases.

Since oral contraceptives (OCs) are the method chosen by an estimated 10 million US women, health care providers must be informed about the pill's mechanism of action, its warning signs and contraindications, and its interaction with other drugs and vitamins. Although nearly 60 OC brands are currently available, there are only 2 basic types: the mini-pill, which contains progesterone only, and the combination OC, which adds estrogen. Combination OCs are further divided into monophasic, biphasic, and triphasic preparations. OC use is contraindicated in women with a history of phlebitis, stroke, coronary artery disease, liver tumors, or breast cancer. Warning signs that patients should be instructed to report include acute abdominal pain, chest pain, headaches, and severe leg pain. The effectiveness of OCs is decreased by drugs such as ampicillin, penicillin V, tetracycline, rifampin, barbiturates, and some antiepileptics. On the other hand, OCs decrease the effects of insulin and oral hypoglycemics, oral anticoagulants, and guanethidine. In addition, OCs can increase the risk of certain nutritional deficiencies, primarily of folic acid and vitamins C, B2, B6, and B12.

A case of intra- and retroperitoneal haemorrhage after a splenic vein aneurysm rupture is described. A 27-year-old woman complained of chest pain on her first postpartum day. Symptoms were initially suggestive of pulmonary embolism, but within 3 h she developed severe acute abdominal pain, abdominal distension and haemodynamic instability. Ultrasound demonstrated a non-echogenic mass in the abdomen suggestive of a fluid collection and a computed tomography scan confirmed the presence of a lesion at the pancreatic tail. Urgent laparotomy revealed splenic vein rupture near the pancreatic tail. Partial pancreatectomy and splenectomy were performed. The patient subsequently made an uneventful recovery. Histological examination revealed a splenic vein aneurysm and chronic inflammatory changes in the pancreatic tissue. Rupture of a splenic vein aneurysm is a rare event and the diagnosis may present difficulty because its presentation is similar to several other more common conditions. However, rupture of a splenic vein aneurysm should be suspected in any pregnant woman with unexplained abdominal pain or with clear signs of haemorrhage, as delay in diagnosis can have devastating consequences.

This article emphasizes on the laboratory investigations that may play a significant role in the prompt management of the patient. Hence, other conditions where laboratory investigations will not play a major role are not included in this article. An attempt has been made to highlight certain issues wherein we can prevent inadvertent ordering of tests to minimize the burden on the overworked emergency laboratory, without compromising patient care. The conditions that will be dealt here include: acute chest pain, acute abdominal pain, road traffic injuries, acute respiratory distress, high grade fever, vomiting, loss of consciousness, poisoning and laboratory accidents, and lastly occupational exposure to potential biological hazards.

Paraesophageal hernias are considered to be benign entities which are usually managed conservatively. We present a case of a middle-aged male with no previous history of esophageal hernia who presented with acute chest and abdominal pain. The patient was diagnosed to have a type 2 paraesophageal hernia with gastro-thorax. Laparotomy was performed during which it was found that herniated segment of the stomach had strangulated and gangrenous. Thoracotomy was performed and gangrenous stomach segment resected. A roux-en-Y esophago-jejunostomy was performed. Diaphragmatic defect was plicated. Patient recovered with adequate post operative support. A review of the literature revealed that paraesophageal hernias presenting as acute abdominal pain is a rare clinical entity and those with gastric gangrene is even rarer, with high mortality rates. We suggest that paraesophageal hernias require to be managed actively considering the seriousness of potential complications and the relative safety of newer elective surgical modalities. A high index of suspicion is needed in order to avoid missing this diagnosis in patients presenting with chest pain.

We report a case of a 43-year-old man who presented to the accident and emergency department with acute abdominal pain. Ultrasound investigation showed non-specific splenic pathology and treatment for a splenic abscess was started. The patient later described a history of episodic, cardiac-sounding chest pain occurring at rest, the most recent case of which (6 days prior to admission) had been unusually severe. ECG showed anterior Q waves and aneurysm-type ST-T segment changes. Echocardiography, coupled with a CT scan of the abdomen, revealed the aetiology. The patient had sustained an anterolateral myocardial infarction, which had led to mural thrombus formation and secondary embolisation to the spleen, with no other end organ damage detected. The patient responded well to conservative management of the splenic infarct and initiation on the acute coronary syndrome pathway. Coronary angiography showed mild disease of the proximal left anterior descending artery. Cardiac MRI at 1 month confirmed an ischaemic aetiology.

Acute chest pain is common in patients with cystic fibrosis (CF). Here we report the case of an adolescent who suffered acute chest pain in September after an history of acute abdominal pain and fever. The reason for this clinical sceneriao was found to be Coxsackievirus B3, known to be responsible of Bornholm disease, a frequent but under recognized viral myositis. The diagnosis is mainly clinical, but evocating this diagnosis may avoid unnecessary exam.

Introduction and aim Pain is a frequent symptom in emergency patients and opioids are commonly used to treat it at emergency departments and at pre-hospital settings. The aim of this systematic review is to examine the efficacy and safety of parenteral opioids used for acute pain in emergency medicine. Method Qualitative review of randomized controlled trials (RCTs) on parenteral opioids for acute pain in adult emergency patients. Main outcome measures were: type and dose of the opioid, analgesic efficacy as compared to either placebo or another opioid and adverse effects. Results Twenty double-blind RCTs with results on 2322 patients were included. Seven studies were placebo controlled. Majority of studies were performed in the emergency department. Only five studies were in prehospital setting. Prehospital studies Four studies were on mainly trauma-related pain, one ischemic chest pain. One study compared two different doses of morphine in mainly trauma pain showing faster analgesia with the larger dose but no difference at 30 min postdrug. Three other studies on the same pain model showed equal analgesic effects with morphine and other opioids. Alfentanil was more effective than morphine in ischemic chest pain. Emergency department studies Pain models used were acute abdominal pain seven, renal colic four, mixed (mainly abdominal pain) three and trauma pain one study. Five studies compared morphine to placebo in acute abdominal pain and in all studies morphine was more effective than placebo. In four out of five studies on acute abdominal pain morphine did not change diagnostic accuracy, clinical or radiological findings. Most commonly used morphine dose in the emergency department was 0.1 mg/kg (five studies). Other opioids showed analgesic effect comparable to morphine. Adverse effects Recording and reporting of adverse effects was very variable. Vital signs were recorded in 15 of the 20 studies (including all prehospital studies). Incidence of adverse effects in the opioid groups was 5-38% of the patients in the prehospital setting and 4-46% of the patients in the emergency department. Nausea or vomiting was reported in 11-25% of the patients given opioids. Study drug was discontinued because of adverse effects five patients (one placebo, two sufentanil, two morphine). Eight studies commented on administration of naloxone for reversal of opioid effects. One patient out of 1266 was given naloxone for drowsiness. Ventilatory depression defined by variable criteria occurred in occurred in 7 out of 756 emergency department patients. Conclusion Evidence for selection of optimal opioid and dose is scarce. Opioids, especially morphine, are effective in relieving acute pain also in emergency medicine patients. Studies so far are small and reporting of adverse effects is very variable. Therefore the safety of different opioids and doses remains to be studied. Also the optimal titration regimens need to be evaluated in future studies. The prevention and treatment of opioid-induced nausea and vomiting is an important clinical consideration that requires further clinical and scientific attention in this patient group.
