X-Ray and Ultrasonography in Forearm Trauma

Introduction

This study aimed to prevent unnecessary exposure to ionising radiation, and to exclude non-fracture cases in children admitted to the emergency department with a forearm trauma, by showing that forearm trauma could be assessed with ultrasonography (USG) as accurately and precisely as with direct radiography.

Methods

A total of 105 patients (67 males and 38 females) were included in the study. Before performing radiography, the patients were assessed with USG and the results were recorded. The findings of USG and radiography were then compared.

Results

A total of 58 (55%) patients had fractures detected with USG. When compared to X-ray, the sensitivity of USG in detecting forearm fractures was 98.3% (95% confidence interval [CI]: 90.7-100%), specificity was 95.8% (95% CI: 86.0-98.9%), negative likelihood ratio was 0.018, positive likelihood ratio was 23.58, negative predictive value was 97.9% (95% CI: 88.7-99.9%), and positive predictive value was 96.6% (95% CI: 88.1-99.6%).

Conclusion

The use of USG on selected cases of paediatric patients may provide a more rapid evaluation so as to reduce exposure to ionising radiation. We believe that USG will be useful in excluding non-fracture cases. (Hong Kong j.emerg.med. 2015;22:352-358)

Accidental Use of Sodium Hypochlorite Instead of Haemodialysis Solution: A Case Report

Haemodialysis that involves diffusion of solutes across a semi-permeable membrane allows excretion of harmful solutes and excess fluids. All dialysis machines are disinfected by chemical agents (e.g. sodium hypochlorite, formaldehyde, glutaraldehyde, peroxyacetic acid). Sodium hypochlorite (NaOCl), which is known as household bleach, is a whitening agent and used in medical treatment and disinfection of tap water. Herein, we present a 66-year-old female patient who was inadvertently connected to NaOCl solution infusion in a routine haemodialysis session. By the time the accident was noticed, approximately 200 ml of undiluted NaOCl cleaning solution (concentration 1.21-1.23 g/ml) had been added to the dialysis bath, soaking the membrane fibres. The patient was admitted to the hospital about 30 minutes after the exposure, and her Glasgow Coma Scale score was recorded as 5/15 (E1, V1, M3). In conclusion, more stringent standards should be enforced in the sterilization of haemodialysis machines and related equipments. Accidental contacts with disinfectants should be prevented in dialysis units.

Spontaneous Ruptured Splenic Artery Aneurysm: A Case Report

Splenic artery aneurysms are rare and occur predominantly in women. Most of them are asymptomatic until the aneurysms rupture. We report a previously healthy 46-year-old female who attended emergency department with abdominal pain for four hours. She had left upper quadrant tenderness and pulsatile mass. Laboratory tests showed her haematocrit 29.8%. Subsequent examinations with ultrasound and computed tomography (CT) showed a large aneurysm of the splenic artery and a heterogeneous hypodense shadows around the aneurysmal sac and perihepatic area. Just after CT scan she collapsed and was taken into emergency surgery. Splenectomy was performed following the ligation of splenic artery proximal to lesion. On the fifth day, she was discharged from the hospital with complete recovery. This case report highlights that rapid resuscitation, diagnostic imaging, surgical consultation, and subsequent laparotomy remain the priorities in patient management.

Anaphylaxis after intravenous infusion of dexketoprofen trometamol

Dexketoprofen trometamol (DT), a nonsteroidal anti-inflammatory drug, is a highly water-soluble salt and active enantiomer of rac-ketoprofen. Its parenteral form is commonly used for acute pain management in emergency departments of our country. Side effects such as diarrhea, indigestion, nausea, stomach pain, and vomiting may be seen after the use of DT. Anaphylactic shock (AS) secondary to infusion of DT is very rare and, to our knowledge, it is the first case report describing this side effect. This case report was presented to emphasize that AS may be seen after the use of DT.

Patients admitted to emergency units with injuries related to the four Hajj-associated annual animal sacrifice feasts from 2010 to 2013

BACKGROUND

During the Eid al-Adha ("Sacrifice Feast") religious holiday in Muslim communities animal sacrifices are made over a period of 3 days every year.

OBJECTIVES

The aim of this study was to determine the type of sacrifice-related injuries, the characteristics of patients, treatments for injuries, and relationships between these factors to determine precautions that could be taken to avoid or mitigate sacrifice-related injuries.

DESIGN

Retrospective study of medical records.

SETTING

Emergency units at two hospitals from 2010 to 2013.

PATIENTS AND METHODS

Patients admitted for treatment for injuries associated with sacrificial cutting during the four annual sacrifice feasts were classified as professional butchers, apprentice butchers, and third persons who were neither professional butchers nor apprentices.

MAIN OUTCOME MEASURE(S)

Injuries associated with animal sacrifice.

RESULTS

Of 592 patients, 22 (3.7%) were professional butchers, 149 (25.2%) apprentice butchers, and 421 (71.1%) third persons. Significant relationships were found between the profession of the injured person and the injury and subsequent treatment (P < .05).

CONCLUSION

To prevent and minimize the injuries associated with sacrificial cutting, there should be an area designated for sacrificing animals. Moreover, sacrifices should be performed by professionals in possession of a sacrificial cutting certificate. If owners of sacrificial animals insist on slaughtering animals, they should be trained by professional butchers who have a teaching certificate. To deal with an increasing number of such injuries during the sacrifice feast, hospital emergency units need to be adequately resourced with adequate equipment and staff.

LIMITATIONS

Regional and local data could not be assessed completely. Patients who presented on the 4th day were not included in the study.

Neuropsychiatric disorders and risk factors in carbon monoxide intoxication

Neuropsychiatric sequelae may be observed in the late phases of carbon monoxide (CO) intoxication. Establishing a link between CO-related neuropsychiatric disorders and associated risk factors may decrease morbidity and mortality by means of appropriate treatment and counseling. The aim of the present study was to determine the relationship between neuropsychiatric outcomes of CO intoxication and demographic and clinical variables. Thirty patients who presented with CO intoxication and had no known neuropsychiatric disease, and 30 healthy controls were included. Physical examinations and laboratory tests were performed. Following the 1st therapy, they underwent mental and psychiatric tests 5 times (the time of discharge, during the 1st week, and during the 1st, 3rd, and 6th months). They underwent cerebral magnetic resonance imaging (MRI) at the end of the 1st month. They were evaluated by cognitive function tests at the 6th month. Lesions relevant to CO intoxication were detected in 46.7% of the patients via cranial computed tomography and in 13.3% via MRI. Evaluation of psychiatric tests revealed a clear decrease in cognitive functions, such as immediate memory, learning, reaching the criterion, spontaneous recall, attention, visual memory, and logical memory. It was found that the patients had anxiety within the 1st month, and the frequency of anxiety reached to the value of the control group by the end of the 6th month. In conclusion, we suggested that CO intoxication might lead to neuropsychiatric disorders. Our results emphasized that in addition to standard treatment, neuropsychiatric evaluation should also be performed in patients with CO intoxication.

An unusual etiology of fever of unknown origin: Foley catheter

Fever may appear due to known causes such as infections, but may sometimes occur as a result of unknown pathologies. These pathologies can be included in a miscellaneous group of fever of unknown origin. We report one case of bladder stone including a foreign body in a 40-year-old man with a stroke admitted for high fever, blocked miction and bladder symptoms.

Air guns: toys or weapons?

Air guns and blank guns may appear relatively harmless at first glance, but they are, in fact, potentially destructive, even lethal, weapons. Approximately 2 to 2.5 million nonpowder firearms are sold annually, and again approximately 12.9 per 100,000 population are treated for such injuries in hospital emergency departments each year in the United States. Unfortunately, these guns are considered to be a toy for children. Therefore, incidents of air gun injuries are gradually increasing. Although such injuries may initially be considered trivial, it may signify severe internal tissue pathologies. These apparently trivial injuries may have catastrophic consequences if unnoticed. In this study, we report 4 cases with head injury due to a shot by these guns. The cases indicate that these people had used the guns belonging to their parents for the purpose of suicide. The cases also show that these machines are not innocent.

Amitraz: an unusual aetiology of Ogilvie's syndrome

Amitraz is an insecticide/acaricide of formamidine pesticides used worldwide for ectoparasites in animals. Because of its widespread use, amitraz poisoning is frequently encountered in Turkey.

CASE REPORT

A 36-year-old, comatose female was admitted to the hospital. Although it was stated that she had taken a glass of water containing amitraz, the exact volume of the substance was unknown. On admission, her Glasgow Coma Scale score was 10/15. Clinical findings were vomiting, miosis, bradycardia and hypotension. The patient's vital signs were body temperature 37.2 degrees C, pulse 54 bpm, blood pressure 80/50 mmHg and pulseoximetry 84%. Supportive treatment consisting of oxygen, fluid replacement and gastric lavage, activated charcoal and atropine was administered. On the second day, signs of Ogilvie's syndrome characterized by severe tenderness, distension and pain in the abdomen were seen. On the third day, the patient's condition improved except for abdominal distension and pain, inability to pass faeces or flatus through the anus. Although continuous nasogastric tube decompression was performed, her complaints were not resolved completely. Neostigmine was administered on the fourth day. On the fifth day, abdominal pain and distension were decreased, and stool passage began. She had a complete clinical and laboratory improvement, which warranted her discharge on the seventh day of admission.

[The investigation of ischemic myocardial damage in patients with carbon monoxide poisoning]

OBJECTIVE

Poisoning with carbon monoxide (CO) due to flash gas heater or stove being an important health problem in our region, causes significant pathologies in the body as well as death by decreasing oxygen-carrying capacity of blood. This study was planned to assess whether or not myocardial damage occurs in patients with CO poisoning.

METHODS

Forty consecutive adult patients with CO poisoning (30 females and 10 males) were included in this study. The mean age of the patients was 28.5+/-9.9 years (range: 15-56). The demographic characteristics, vital signs, the origin of CO gas, risk factors for coronary artery disease (CAD) and smoking habit of the patients were recorded. The evaluation of Glasgow Coma Scale score, electrocardiogram (ECG), peripheral arterial blood gases, complete blood count, creatine kinase (CK), creatine kinase-myocardial band (CKMB), troponin-T measurements were performed in all cases. Additionally, myocardial perfusion SPECT was performed in three cases with carboxyhemoglobin (COHb) levels over 50%.

RESULTS

Sinus tachycardia, was observed in 9 cases. Ventricular bigeminy was seen in a case with troponin-T positive test. Six of 40 cases (15%) had significantly increased CK and CK-MB levels with normal troponin-T measurements. High troponin-T levels (0.13 ng/ml) were detected only in 1 case with COHb level of 61.3%. Myocardial SPECT was performed in 3 cases with COHb levels higher than 50% and no images compatible with defects could be identified.

CONCLUSION

The results suggested that significant myocardial damage and life-threatening cardiac hemodynamic changes do not develop in CO-poisoned patients with COHb level below 60 % and without any known underlying CAD. It is not necessary to routinely measure CK, CK-MB and troponin-T, and perform myocardial perfusion SPECT in acute CO poisoning cases without any ECG abnormality, ischemic cardiac symptoms or known CAD.

Speed bump–induced spinal column injury

INTRODUCTION

Compression fracture of the vertebral body is common, especially in older adults. Injuries to the spinal column are one of the most frequent injuries by accidents and falls from heights. Vertebral fracture associated with minor trauma, however, is a rare occasion.

CASE REPORT

Five cases were injured in the inner city buses after passing onto speed bumps are presented. On presentation, four patients complained of severe pain in the thoracolumbar region, while in the other patient, physical examination revealed pain and tenderness on the neck. No neurologic deficit was noted except for one patient with tenderness on thoracic spines. Examination of the thoracolumbar X-ray and computed tomography displayed compression fractures in four patients. Other laboratory data obtained on admission were within normal limits. Posterior instrumentation was applied to three patients. All patients recovered well except for the one with cervical fracture.

CONCLUSION

Drivers should be strongly warned and educated on the potential hazards of traversing past such bumps in roads too fast and such barriers should be built regarding tested standards.
