A rare case of Dysphagia secondary to a large oesophageal lipoma.

Dysphagia is considered a warning symptom that requires exclusion of significant pathology such as oesophageal cancer, especially in elderly patients. Benign neoplasms of the oesophagus are rare. We report the case of a 69-year-old lady who presented with a five years history of infrequent intermittent dysphagia that had rapidly progressed over one month. This was associated with globus sensation, weight loss, intermittent episodes of stridor and aspiration pneumonia. Investigations revealed a large oesophageal lipoma in the proximal oesophagus extending down to the lower oesophagus. This was successfully resected via a left cervical approach. She remained well two years after the surgery.

Gabapentin toxicity: an important cause of altered consciousness in patients with uraemia.

Gabapentin toxicity should be considered one of the differential diagnoses of altered consciousness in patients with compromised renal function even after a single dose. We report a 57-year-old woman with diabetes mellitus and uraemia on regular haemodialysis who developed severe dizziness and lethargy after a single recommended dose of gabapentin for bilateral leg dysthesia. Because of progressive drowsiness and decreasing level of consciousness, one session of haemodialysis was performed and clinical recovery was dramatic. The adverse effects of gabapentin seem to vary from person to person and should be viewed with a high degree of suspicion, especially in patients taking this drug at the beginning.

Ovarian torsion caused by teratoma masquerading as renal colic.

Ovarian torsion is a well known but poorly recognised disease and prompt treatment is necessary to avoid adverse outcomes. We report a patient with severe right flank pain initially diagnosed as renal colic. She was brought to our emergency department because of persistent pain. After further investigation, ovarian torsion caused by teratoma was diagnosed. Because of the timely management, the patient made a good recovery. This is an uncommon but important case that emergency physicians should be aware of.

Differences between emergency patients and their doctors in the perception of physician empathy: implications for medical education.

CONTEXT AND OBJECTIVES: Conveying empathy is a multi-phase process involving an inner resonation phase, communication phase, and reception phase. Previous investigations on physician empathy have focused on a physician's inner resonation phase or communication phase and not on the patient's reception phase. The purpose of this study was to investigate the differences in the perception of physicians' empathy between emergency physicians (EPs) and their patients. The answer to this question will allow us to more fully understand all phases of empathy and will help guide the teaching of how to effectively communicate empathy in the clinical setting. METHODS: From 2004 to 2005, we conducted in-depth, semi-structured interviews with 7 each of EPs, patients, patients' family members and nurses. A phenomenological approach was used to analyze the data. RESULTS: Four themes emerged from the analysis: (1) When patients expressed their feelings, EPs usually did not resonate with their concerns; (2) Patients needed EPs to provide psychological comfort, but EPs focused only on patients' physical discomfort; (3) Patients needed appropriate feedback from EPs, but EPs did not reflect on whether their patients had received empathy from them; (4) EPs' ability to empathize was affected by environmental factors, which EPs found difficult to overcome. CONCLUSION: EPs and their patients perceive the physicians' empathy differently. These findings provide insights into patients' perceptions of their physicians' empathic expressions and provide a framework for teaching physicians how to convey empathy in the emergency department setting.

Predictors of long-term neurological outcomes in non-accidental head injury.

BackgroundNon-accidental head injury (NAI) is an inflicted injury usually on a child, often resulting in long-term neurological impairment and occasionally death. This study aimed to investigate the predictive values of acute findings, especially ocular, for long-term neurological outcomes.MethodsMedical records including retinal images of all children who attended the local Children's hospital with a diagnosis of NAI from over a period of 5 years were reviewed and data collected via the electronic patient record system. Patient demographics, injuries sustained, wide-field digital retinal images, visual acuity and sequalae, neurological function, and global function was noted. IBM SPSS software program was used for statistical analysis.ResultsOf the 38 patients (24 males, 14 females), 12 children died acutely from the head injury with the remaining 26 children available for long-term follow-up. A younger age of injury (P=0.004) was the only statistically significant predictor of good neurological outcome as compared with absence of macular retinoschisis, unilateral retinal haemorrhage, and unilateral subdural haemorrhage. Of the 38 children, 17 children had retinoschisis; 9 children with macular retinoschisis died acutely while 4 suffered a degree of developmental delay and only 4 were developmentally normal at the last follow-up. Long-term visual acuity data was available for 18 of the 26 survivors (range: NPL to Snellen 6/5). A statistical significance was noted between retinoschisis and worsened visual acuity (P<0.05).ConclusionsBilateral macular retinoschisis on acute presentation of NAI is associated with a seven-fold and unilateral with a four-fold increase in the development of a poor neurological outcome and eventual death. Conflicting to other studies, younger children presented better neurological outcomes.

Xanthogranulomatous pyelonephritis with reno-colic fistula: A rare complication of urinary tract infection.

Urinary tract infection (UTI) is one of the most common presentations in general practice and, in most instances, occurs in a single episode and is easily treated with a course of anti-microbial therapy. In the case of recurrent urinary tract infections, it is important to consider evaluation for any underlying causes. We report the case of a 32 year old female who had recurrent UTIs; this was a case of recurrent UTI secondary to xanthogranulomatous pyelonephritis from renal stones with resultant reno-colic fistula formation.

Mesenteric injury caused by minor blunt abdominal trauma.

The authors present an unusual case of mesenteric injury caused by minor blunt abdominal trauma and also provide a review of the literature.

Risk stratification of severe sepsis patients in the emergency department.

OBJECTIVE: To determine the efficacy of the Mortality in Emergency Department Sepsis (MEDS) score in the stratification of patients who presented to the emergency department (ED) with severe sepsis. METHODS: Adults who presented to the ED with severe sepsis were retrospectively recruited and divided into group A (MEDS score <12) and group B (MEDS score > or =12). Their outcomes were evaluated with 28 day hospital mortality rate, length of hospital stay, Kaplan-Meier survival analysis, and receiver operating characteristic (ROC) analysis. Discriminatory power of the MEDS score in mortality prediction was further compared with the Acute Physiology and Chronic Health Evaluation (APACHE) II model. RESULTS: In total, 276 patients (44.6% men and 55.4% women) were analysed, with 143 patients placed in group A and 133 patients in group B. Patients with MEDS score > or =12 had a significantly higher mortality rate (48.9% v 17.5%, p<0.01) and higher median APACHE II score (25 v 20 points, p<0.01). Significant difference in mortality risk was also demonstrated with Kaplan-Meier survival analysis (log rank test, p<0.01). No difference in the length of hospital stay was found between the groups. ROC analysis indicated a better performance in mortality prediction by the MEDS score compared with the APACHE II score (ROC 0.75 v 0.62, p<0.01). CONCLUSION: Our results showed that mortality risk stratification of severe sepsis patients in the ED with MEDS score is effective. The MEDS score also discriminated better than the APACHE II model in mortality prediction.

Atypical manifestation of Vibrio vulnificus septicaemia.

Vibrio vulnificus is a Gram-negative marine bacterium that may cause local wound infection, gastroenteritis, or septicaemia. Fatal septicaemia usually presents with fever, shock, and large haemorrhagic bullae on the legs. This report is about a man who had severe V. vulnificus septicaemia but presented with atypical features of leg pain and diffuse purpuric skin lesions. V. vulnificus septicaemia should be suspected if the following are present: septic shock, leg pains associated with diffuse purpuric skin lesions, recent consumption of raw seafood, and a past medical history of liver cirrhosis.

Isolated oculomotor nerve palsy from minor head trauma.

Isolated third cranial nerve palsies in head trauma patients can be the result of direct or indirect damage to the oculomotor nerve. They are usually associated with severe head trauma. We reported a case of isolated oculomotor nerve palsy associated with minor head injury. No initial loss of consciousness was recalled. Computed tomography (CT), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA) of the brain were normal. Previous reports in the literature were reviewed and the possible mechanism of injury was discussed. Head injuries are commonly seen in sports settings. Our case illustrated that even minor head trauma can cause isolated oculomotor nerve palsy in the absence of abnormal brain imaging findings.

An unusual presentation of baclofen overdose.

Baclofen has become increasingly popular in the treatment of spasticity disorders. Its availability for misuse has also increased. We report a case of baclofen overdose in a 20-year-old man, who manifested atypical symptoms of baclofen overdose--that is, delirium and rhabdomyolysis. He was treated successfully with full supportive management, and was discharged from the hospital on the 12th day following admission. If a past medication history is not immediately available, baclofen overdose should be included in the differential diagnosis of an acutely confused patient complicated with rhabdomyolysis, as routine toxicology screening does not include baclofen.

Evaluation of blunt abdominal trauma: current practice in Taiwan.

OBJECTIVE: To gain an overview of the current practice of different major institutions in Taiwan in the evaluation of abdominal injuries. A further comparison was made between general surgeons and emergency physicians in this aspect. METHOD: A telephone survey was conducted of all emergency departments of 58 major institutions (14 medical centres, 44 district hospitals) that are capable of providing definitive care for trauma victims in Taiwan in June 2002. Respondents were asked to select the diagnostic modality of choice in the evaluation of a haemodynamically abnormal blunt trauma victim with suspected intra-abdominal injuries. In the same study period, this particular telephone scenario was also used to survey 109 individual doctors (45 emergency physicians, 64 general surgeons). RESULTS: Most respondents preferred ultrasound (also known as focused assessment with sonography for trauma or "FAST") instead of diagnostic peritoneal lavage (DPL) because DPL is invasive and most doctors in Taiwan have limited experience in performing DPL or interpreting the results. CONCLUSIONS: It seems reasonable to devote greater resources for emergency departments to incorporate a FAST based algorithm into their initial management of trauma victims, and to improve training in its use. It is also suggested that future ATLS teaching in Taiwan should include didactic material on FAST.

Comparison of lidocaine and bronchodilator inhalation treatments for cough suppression in patients with chronic obstructive pulmonary disease.

BACKGROUND: This study aimed to assess and compare the effectiveness of lidocaine and bronchodilator inhalation treatments for rapid cough suppression in patients with chronic obstructive pulmonary disease (COPD). METHODS: Prospective comparison study carried out in a tertiary emergency department. Consecutive COPD patients presenting with intractable cough were randomly assigned to receive lidocaine or terbutaline inhalation treatments for cough suppression. Patients with dyspnoea, unstable vital signs, and pneumonia or neoplasm on chest x ray were excluded. A subjective, 10 point questionnaire based cough severity score was used for assessing the outcome. RESULTS: The final study sample included 127 patients (mean (SD) age, 69.2 (12.1) years; 33.1% women) of whom 62 received nebulised lidocaine and 65 nebulised bronchodilator. The cough severity score was significantly reduced one hour after inhalation treatment with both lidocaine and bronchodilator, with no significant difference in efficacy. Common but mild side effects in the lidocaine group included oropharyngeal numbness and bitter taste, and, in the bronchodilator group, tremor and palpitation. Dyspnoea, dizziness, and nausea and vomiting were equally uncommon in both groups. None of these problems caused any of the patients to discontinue their treatments and no allergic reactions were reported. CONCLUSIONS: Both lidocaine and bronchodilator inhalation treatments are equally effective for short term cough suppression in patients with COPD.

Preconsultation use of analgesics on adults presenting to the emergency department with acute appendicitis.

OBJECTIVE: 279 cases of appendicitis were reviewed and compared for the difference between those patients who received pain medication before consulting a surgeon and those who were not treated with analgesics. METHODS: All patients aged 15 years and older who underwent appendicectomy for appendicitis between 1 July 2001 and 30 June 2002 were divided into group 1 (those who received preconsultaion use of analgesics) and group 2 (those who were not treated with analgesics). The following measures were compared: age, sex, symptom duration, initial vital signs, white blood cell counts, frequency of imaging studies, time to operative intervention, and operative findings. Continuous and categorical variables were analysed using t and chi(2) tests, respectively. RESULTS: A total of 279 patients were included for analysis. Patient details (age, sex, symptom duration) of the two study groups were similar. There was no statistically significant difference between group 1 and group 2 with respect to vital signs (systolic blood pressure, pulse rate, respiratory rate, body temperature), white blood cell counts, and frequency of imaging studies (ultrasound, computed tomography). There was no significant difference in the rate of perforated appendicitis between the two study groups although a shorter median time to operative intervention has been found in the group who received analegesia. CONCLUSION: The preconsultation use of analgesics in ED patients with a final diagnosis of appendicitis is not associated with a longer delay to operative intervention and is not associated with an increased rate of perforated appendicitis.
