An unusual localization of snakebite treated without antivenin: case report

Snakebite is one of the commonest causes of morbidity and mortality in tropical regions. This paper focuses on the medical treatment of a patient who had been bitten by a snake on the vertex of his head. It was a severe envenomation with ensuing marked edema associated with coagulation abnormalities. Although the antivenin was extensively sought in various medical centers, it was unavailable. We observed and treated the patient, with special regard to his hematological findings and potential complications. Specifically, tetanus prophylaxis and intravenous fluids were administered, and the wound was cleaned and dressed. Fresh frozen plasma was also administered. The patient responded well, and was discharged on the fourth day of his admission, without any sequelae.     

Intraocular Pressure Change in Orbital Disease

Intraocular pressure change has been found concurrent with many orbital pathologies, particularly those involving proptosis. The objective of this review is to offer an inclusive classification of orbital disease–related intraocular pressure change, not only for oculoplastics and glaucoma specialists, but also for general ophthalmologists. Various orbital conditions associated with increased intraocular pressure and glaucoma are comprehensively summarized, and pathophysiology, clinical manifestations, and treatment options of these diseases are discussed. Graves disease, arterio-venous shunts, trauma, and orbital neoplasia, and other common conditions are discussed in detail; less frequent syndromes such as orbitocraniofacial deformities, phakomatoses, and mucopolysaccharidoses are included for the sake of comprehensiveness, but discussed less extensively.     

The effect of parathion-methyl and antidotes on parotid and pancreatic glands: a pilot experimental study

The objective of this study is to investigate the functions of parotid and pancreatic glands in response to intoxication with parathion-methyl (PM) and the effects of treatment in rats. Seventy-five male Wistar rats were divided equally into five groups: Group I, control; group II, received atropine and pralidoxime (2-PAM) for 24 h, but no PM; group III, oral PM but no atropine and 2-PAM; group IV, PM and atropine for 24 h and 2-PAM; group V, PM and atropine for 96 h and 2-PAM. After the administration of the chemicals, blood samples were drawn to test for amylase, lipase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE), while pancreatic and parotid glands of each rat were removed for light microscopic examination. Amylase levels were found significantly elevated in groups II, III, IV, and V, whereas lipase levels were supranormal in groups III, IV, and V. The blood levels of AChE were decreased in groups III and IV and BChE were decreased in II, III, IV, and V. No evidence of pancreatitis and parotitis was identified in the histopathologic evaluation in any group in 96 h; however, hyperchromasia, irregularity in nuclei, and binuclear cells were observed in all parotid glands in group V. Parotitis and pancreatitis were not evident; however, hyperamylasemia and hyperlipasemia were found, whereas various histologic changes in parotid glands were documented in the groups that were administered organophosphate and treatment.     

Anxiety disorder in patients with non-specific chest pain in the emergency setting

Objectives

Many patients who have been discharged from the emergency department (ED) with a diagnosis of “non‐specific chest pain” (NSCP) have anxiety disorder (AD), a commonly missed entity in acute care. The objective of this study was to delineate characteristic properties that could enhance recognition of AD in ED patients admitted with NSCP.

Methods

All patients between 18 and 65 years of age diagnosed with NSCP were enrolled. The Hospital Anxiety and Depression Scale (HADS) anxiety subscale was used as a screening test for AD. The patients with high HADS scores (⩾10) were evaluated by a psychiatrist for AD.

Results

In total, 157 patients were enrolled in the study. HADS scores were found to be "high" (⩾10) in 49 patients (31.2%). Patients with high HADS scores had a higher frequency of associated symptoms (p = 0.004). Dizziness or lightheadedness, chills or hot flushes, and fear of dying were found to have been reported more frequently by patients with high anxiety scores. Of the group with high score, 33 patients (67.3%) were interviewed by a psychiatrist, and 23 (69.7%) of these patients were diagnosed with AD. Associated symptoms were described by 21 patients with AD (91.3%). Of those with AD, 18 (78.3%) had been previously admitted to the ED with chest pain. Atypical chest pain was described by 21 patients (91.3%).

Conclusions

Physicians should always consider AD in patients presenting to the ED with chest pain after ruling out organic aetiology. Patients'' definition of atypical pain, recurrent admissions to ED, and presence of associated symptoms such as dizziness, chills or hot flushes, and fear of dying could aid in considering AD.     

Burnout: need help?

Background  

Burnout syndrome is a psychological situation induced with working, especially in high-risk parts of the hospitals that affects the physical and mental conditions of the staff. The aim is to identify the characteristics of the staff related to Burnout Syndrome in the Emergency Department (ED).     

Prognostic value of thyroid hormone levels in acute myocardial infarction: just an epiphenomenon?

The purpose of this study was to investigate whether thyroid hormone levels have any predictive value for mortality in patients presenting to the emergency department with acute myocardial infarction (AMI). Three groups of patients admitted to the emergency department within the 11-month study period were considered eligible: 95 patients with chest pain and proven AMI, 26 patients with chest pain and no AMI, and 114 patients who served as controls with no evidence of any major disease. Cardiac enzymes and the following thyroid hormones were analyzed and compared between groups, regarding effects of historical and demographic factors: thyrotrophin, free triiodothyronine (FT3), total triiodothyronine (TT3), free thyroxine (FT4), and total thyroxine (TT4). Sixteen patients with AMI (16.8%) died within the study period. Troponin T and creatine kinase-B with an M-type subunit levels were significantly higher in the nonsurvivors when compared with survivors. Survivors in the AMI group had higher TT3, TT4, and lower FT4 levels, while the nonsurvivors in the AMI group had higher thyrotrophin and lower TT3, FT3 and FT4 levels than controls. In the AMI group, the nonsurvivors had lower TT3 and FT3 levels than the survivors. A history of diabetes mellitus and/or angina, TT3, or FT3 was an independent predictor of mortality. TT3 and FT3 appear to be independent prognostic factors in patients with AMI.     

The radioprotective effects of WR-2721 on radiation-induced goblet cell loss.

We assessed the efficacy of the radioprotective effects of WR-2721 in radiation-induced goblet cell loss. Fourteen female New Zealand white rabbits were divided into radioprotected, radiounprotected, and control groups. Ten rabbits received 5,000 rad of beta irradiation to the temporal conjunctiva of both eyes. The right eyes were pretreated with topical applications of WR-2721 30 minutes and 1 minute before irradiation. The left eyes received irradiation only. Four additional rabbits received neither irradiation nor pretreatment with WR-2721. After a 2-month waiting period, each animal was killed and goblet cell densities per high-power field (GCD/HPF) were determined over the areas in question and compared using paired sample t tests. The mean GCD/HPF for the radioprotected, unprotected, and control groups were 10.93, 4.68, 23.15 (right eye), and 26.25 (left eye). Paired sample t tests showed a significant radioprotective effect when comparing WR-2721-treated animals with those receiving radiation only (p less than 0.003). Independent sample t tests showed significant goblet cell loss in both the radioprotected (p less than 0.018) and radiounprotected eyes (p less than 0) when compared with control groups. These data suggest a radioprotective effect of WR-2721 in radiation-induced goblet cell loss.
