How do Physicians Manage Functional Neurological Symptom Disorder and Somatic Symptom Disorder in the Emergency Department? A Vignette Study.

INTRODUCTION: We aimed to explore how physicians from different specialties approach the management of functional neurological symptom (conversion) and somatic symptom disorders in the emergency department compared with pulmonary embolism and how physicians' professional and personal characteristics influence their diagnostic preferences. METHODS: Using a vignette methodology, and cross-sectional design, three emergency department case vignettes of possible functional neurological symptom, somatic symptom disorder, and pulmonary embolism were presented to physicians from internal medicine, emergency medicine, and psychiatry. A structured survey including questions on diagnosis and management of these cases, and physicians' professional and personal characteristics (childhood trauma, attachment style) was conducted. RESULTS: Physicians from internal medicine and emergency medicine tended to consider functional neurological symptom disorder as 'malingering' while psychiatrists tended to diagnose the pulmonary embolism case as a psychiatric condition. Emergency medicine physicians preferred to manage functional neurological symptom disorder themselves, while other doctors endorsed recommending a psychiatric consultation. In the univariable model, being a physician from psychiatry, emergency medicine, or internal medicine; being a specialist, history of childhood sexual abuse, dismissive, and fearful attachment styles of doctors were significant predictors of diagnosing functional neurological symptom disorder as malingering. Being a psychiatrist stayed as the only significant predictor in the multivariable model. CONCLUSION: Objectively-aberrant functional neurological symptoms and subjective somatic symptoms may be creating different reactions in physicians. In the emergency department, physicians' diagnostic and treatment preferences of conversion disorder may be influenced by lack of training in conversion disorder, rather than their personal characteristics.

Conventional vs invert-grayscale X-ray for diagnosis of pneumothorax in the emergency setting.

INTRODUCTION: Pneumothorax is a pathologic condition in which air is accumulated between the visceral and parietal pleura. After clinical suspicion, in order to diagnose the severity of the condition, imaging is necessary. By using the help of Picture Archiving and Communication Systems (PACS) direct conventional X-rays are converted to gray-scale and this has become a preferred method among many physicians. METHODS: Our study design was a case-control study with cross-over design study. Posterior-anterior chest X-rays of patients were evaluated for pneumothorax by 10 expert physicians with at least 3years of experience and who have used inverted gray-scale posterior anterior chest X-ray for diagnosing pneumothorax. RESULTS: The study included posterior anterior chest X-ray images of 268 patients of which 106 were diagnosed with spontaneous pneumothorax and 162 patients used as a control group. The sensitivity of Digital-conventional X-rays was found to be higher than that of inverted gray-scale images (95% CI (2,08-5,04), p<0,01). There was no statistically significant difference between the gold standard and digital-conventional images (95% CI (0,45-2,17), p=0,20), while the evaluations of the gray-scale images were found to be less sensitive for diagnosis (95% CI (3,16-5,67) p<0,01). CONCLUSION: Inverted gray-scale imaging is not a superior imaging modality over digital-conventional X-ray for the diagnosis of pneumothorax. Prospective studies should be performed where diagnostic potency of inverted gray-scale radiograms is tested against gold standard chest CT. Further research should compare inverted grayscale to lung ultrasound to assess them as alternatives prior to CT.

Baseline characteristics and the association between hyponatraemia and pulmonary embolism prognosis.

OBJECTIVE: To evaluate the effect of hyponatraemia on pulmonary thromboembolism mortality rates. METHODS: The retrospective study was conducted at the Cumhuriyet University Medicine Faculty's Emergency Department, and involved the analysis of records related to all patients who were diagnosed with acute pulmonary thromboembolism between January 2005 and June 2011. Diagnoses were confirmed by pulmonary angiography, multi-slice computed tomography or high-probablity ventilation/perfusion scintigraphy. All patients (n=260) were over 16 years of age. SPSS 14 was used for statistical analysis. RESULTS: Plasma sodium level, platelet count and hospitalisation time were significiantly lower among those who died (n=16; 6.29) (p<0.005, p<0.035, p<0.035). Pearson correlation analysis found a negative correlation between plasma sodium level and C-reactive protein, white blood cells and pulmonary artery pressure (r = -0.238, p<0.001; r = -0.222, p<0.001; r = -0.444, p<0.018 respectively). A positive correlation was found between plasma sodium level and hospitalisation time (r=0.130; p<0.039). CONCLUSION: While mortality rates in hyponatraemic pulmonary thromboembolism patients increases, low plasma sodium is an easy parameter that should be kept in mind for the prognosis of pulmonary thromboembolism disease.

Effects of spinal immobilization devices on pulmonary function in healthy volunteer individuals.

BACKGROUND: We aimed to investigate the effects of spinal immobilization devices on pulmonary functions. METHODS: This study was a cross-over trial in healthy volunteer subjects; 60 volunteers were included. We performed a full spirometry in the supine position, and forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and FEV1/FVC were recorded in all subjects. Then, Philadelphia type cervical collar (Philly) and Kendrick extrication device (KED) were applied to all subjects. We measured FVC, FEV1, FEV1/FVC in all subjects in the supine position at the 5th and 30th minutes after application of cervical collar and KED. After a one-hour relaxation period, Philly and long spinal backboard with straps were applied to all subjects. FVC, FEV1, FEV1/FVC were measured again in all subjects at the 5th and 30th minutes after application of cervical collar and long spinal backboard. RESULTS: After application of KED, baseline levels were compared with levels at the 5th and 30th minutes. Statistically significant decreases were determined in FEV1 (p=0.000) and FVC levels (p=0.000) after application of KED, but there were no significant differences in FEV1/FVC levels. After application of the long spinal backboard, a comparison of baseline levels and levels at the 5th and 30th minutes demonstrated statistically significant decreases in FEV1 (p=0.000) and FVC levels (p=0.000), but no significant difference in FEV1/FVC levels. CONCLUSION: We determined that both KED and long spinal backboard cause a decrease in pulmonary functions.

Mushroom poisoning: retrospective analysis of 294 cases.

OBJECTIVE: The objective of this study was to present special clinical and laboratory features of 294 cases of mushroom poisoning. MATERIALS AND METHODS: In this retrospective study, 294 patients admitted to the Pediatric and Adult Emergency, Internal Medicine and ICU Departments of Cumhuriyet University Hospital were investigated. RESULTS: Of 294 patients between the ages of 3 and 72 (28.97 +/- 19.32), 173 were female, 121 were male and 90 were under the age of 16 years. One hundred seventy-three patients (58.8%) had consumed the mushrooms in the early summer. The onset of mushroom toxicity symptoms was divided into early (within 6 h after ingestion) and delayed (6 h to 20 d). Two hundred eighty-eight patients (97.9%) and six (2.1%) patients had early and delayed toxicity symptoms, respectively. The onset of symptoms was within two hours for 101 patients (34.3%). The most common first-noticed symptoms were in the gastrointestinal system. The patients were discharged within one to ten days. Three patients suffering from poisoning caused by wild mushrooms died from fulminant hepatic failure. CONCLUSION: Education of the public about the consumption of mushrooms and education of health personnel working in health centers regarding early treatment and transfer to hospitals with appropriate facilities are important for decreasing the mortality.

Sensitivity and specificity of rapid antigen detection testing for diagnosing pharyngitis in the emergency department.

Acute pharyngitis in adults is primarily a viral infection; only about 10% of cases are of bacterial etiology. Most cases of bacterial pharyngitis are caused by group A beta-hemolytic streptococci (GABHS). One laboratory method for the diagnosis of GABHS is rapid antigen diagnostic testing (RADT), which can be processed during an emergency department visit and which has become a popular alternative to throat swab cultures. We conducted a study to define the sensitivity and specificity of RADT, using throat culture results as the gold standard, in 100 emergency department patients who presented with symptoms consistent with streptococcal pharyngitis. We found that RADT had a sensitivity of 68.2% (15 of 22), a specificity of 89.7% (70 of 78), a positive predictive value of 65.2% (15 of 23), and a negative predictive value of 90.9% (70 of 77). We conclude that RADT is useful in the emergency department when the clinical suspicion is GABHS, but results should be confirmed with a throat culture in patients whose RADT results are negative.

Acute mercury poisoning: a case report.

BACKGROUND: Mercury poisoning can occur as a result of occupational hazard or suicide attempt. This article presents a 36-year-old case admitted to emergency department (ED) due to exposure to metallic mercury. CASE PRESENTATION: A 36-year-old woman presented to the ED with a three-day history of abdominal pain, diarrhea and fever. One week ago her daughter had brought mercury in the liquid form from the school. She had put it on the heating stove. One day later, her 14-month old sister baby got fever and died before admission to the hospital. Her blood pressure was 134/87 mmHg; temperature, 40.2 degrees C; heart rate 105 bpm and regular; respiration, 18 bpm; O2 saturation, 96%. Nothing was remarkable on examination and routine laboratory tests. As serine or urinary mercury levels could not be tested in the city, symptomatic chelation treatment with N-acetyl cysteine (NAC) was instituted with regard to presumptive diagnosis and history. At the 7th day of admission she was discharged without any sequelae or complaint. At the discharge day blood was drawn and sent for mercury levels which turned out to be 30 microg/dL (normal range: 0-10 microg/dL). CONCLUSION: Public education on poisoning and the potential hazards of mercury are of vital importance for community health.

A rare clinic presentation of abdominal pain: rupture of splenic artery aneurysm: a case report.

BACKGROUND: Splenic artery aneurysms (SAA) are uncommon but the most common visceral artery aneurysm. Splenic artery aneurysms are important to recognize because up to 25% may be complicated by rupture and the mortality rate after rupture is between 25% and 70%. CASE REPORT: We present a patient who have abdominal pain. Previously healthy 22-year-old female admitted to emergency department with abdominal pain. Her physical examination reveals only left upper quadrant tenderness. Suddenly she developed hypovolemic shock. On emergent laparotomy massive blood collection within peritoneal cavity and retroperitoneal space at the left upper quadrant was detected. The source of bleeding was evident as rupture of splenic artery aneurysm. Splenectomy was performed following the ligation of splenic artery proximal to lesion. On the tenth day she was discharged from the hospital with complete recovery. CONCLUSION: It is important to remember rupture of splenic artery aneurysm in patients with abdominal pain and hypovolemic shock status.

An unusual cause of allergy: Case report of normal saline solution allergy.

Anaphylaxis and acute allergic reactions may sometimes be fatal. They occur within minutes in a sensitized individual. So quick diagnosis and management are necessary issues. In the literature, cases are widely reported against allergens found in drugs, foods and their additives, radiocontrast material, bee stings, and many other materials. Here, we present a 37-year-old woman who developed an anaphylactic reaction to normal saline infusion during evaluation for her acute abdominal pain. We found only one report about normal saline allergy in the literature (Litvin ME, Shemchuck AS, Lisetskii VA. Anaphylactic shock caused by intravenous injection of isotonic solution of sodium chloride. Klin Khir 1976;(7):59-61).

[Effects of co-morbid disease and drug consumption on trauma patients 65 years of age and older: a university emergency department experience]. / Altmisbes yas ve üstü travmali hastalarda yandas hastalik ve ilaç kullaniminin travma üzerine etkileri: Universite acil servis deneyimi.

BACKGROUND: The objective of this study was to evaluate the causes and demographics of trauma patients 65 years of age and older, and also the effects of co-orbidities and drug use on trauma. METHODS: This study was performed in Medicine Faculty of Yeditepe University Hospital Department of Emergency Medicine Outpatients Clinic between January 2005 - February 2006. Ninety-one trauma patients (48 males [52.7%], 43 females [47.3%]; mean age 73+/-5.42; range 65 to 92 years) 65 years of age and older were included into the study. Age, gender, trauma causes, injury types, co-morbidities, drug consumption and injury severity scores were recorded onto the study form. RESULTS: Fifty-seven (62.6%) patients were admitted to the emergency department because of low-energy fall, 13 patients (14.3%) for high-energy falls, 6 patients (6.6%) for low-energy motor vehicle crush, and 14 patients (15.4%) for high-energy motor vehicle crush. Hypertension was significantly more frequent in falls than the other trauma mechanisms (p=0.003). There was a higher rate of femur fracture in low-energy falls than the others (p=0.026). However, the rate of vertebral fracture was higher in high-energy falls (p=0.037). Soft tissue injuries were seen most often in low-energy motor vehicle crush injuries (p=0.01) while rib fractures were seen most frequently in high-energy motor vehicle crush injury (p<0.01). CONCLUSION: Acute or chronic disease and drug side effects may facilitate the exposure of elderly people to trauma. Drug consumption, co-morbid diseases and trauma causes should be taken into consideration during the evaluation of elderly trauma patients.

Role of papaverine hydrochloride administration in patients with intractable renal colic: randomized prospective trial.

OBJECTIVES: To evaluate the therapeutic effect of papaverine hydrochloride in the treatment of patients with renal colic pain unresponsive to conventional treatment. METHODS: From March 2007 to January 2008, a total of 561 patients with severe renal colic pain due to a ureteral stone were treated with conventional agents (hyoscine-N-butylbromide and diclofenac sodium) in the emergency and urology departments. Of these 561 patients, 110, with no response to the treatment and persistent severe pain, were randomized into 3 groups for additional treatment. The patients in group 1 (n = 37) received intravenous hyoscine-N-butylbromide, those in group 2 (n = 37) received papaverine hydrochloride, and those in group 3 (n = 36) received pethidine. Before and after treatment, all patients completed a visual analog scale (VAS) questionnaire, with a scale of 0 (no pain) to 10 (maximal complaint), to measure their subjective pain. The mean VAS score of each group was compared with that of the other groups. RESULTS: The pretreatment mean VAS scores of all 3 groups were not significantly different statistically from each other (4.02 +/- 1.20, 4.36 +/- 1.97, and 4.27 +/- 1.50; P > .05). However, after treatment, the mean VAS scores of the patients treated with papaverine (0.93 +/- 0.29) and pethidine (0.81 +/- 0.38) were significantly different from those of the hycosine group (3.67 +/- 2.21; P < .001). However, the mean VAS scores of groups 2 and 3 were comparable (P = .67). Unlike opioids, no papaverine-related severe side effects were observed. CONCLUSIONS: Our results indicate that papaverine hydrochloride can used in an effective manner in the management of renal colic pain in patients unresponsive to commonly used conventional agents.

Acute aortic dissection with painless paraplegia: report of 2 cases.

Acute aortic dissection is often a life-threatening event that usually presents as a sudden, severe, exquisitely painful, ripping sensation in the chest or back. There are a few reports of atypical findings or no pain in the literature. We report 2 patients with painless acute aortic dissection who presented to the emergency department (ED) with sudden onset paraplegia.
