Role of N-acetylcysteine and vitamin B complex in improving outcomes of corrosive ingestion.

Background: Corrosive ingestion remains a worldwide public health problem. To date, there are no specific medications with approved efficacy in reducing gastrointestinal injury progression following corrosive ingestion. Aim: The current study assessed the efficacy of N-acetylcysteine (NAC) and vitamin B complex as adjuvant therapy in improving the outcome of patients with corrosive ingestion. Subjects and methods: The study included 92 patients with acute corrosive ingestion admitted to Alexandria Poison Center. Patients were distributed into four equal-sized groups and managed as such; Group I received the standard treatment protocol. The other three groups received IV antioxidants in addition to the standard treatment; Group II received NAC, Group III received vitamin B complex, and Group IV received both NAC and vitamin B complex. To assess occurrence of delayed complications, barium swallow and meal were done 21 days after acute corrosive ingestion, and every patient was followed up for one year. Results: Start of oral intake was earliest among patients in Group II, and as a result, the need for parenteral nutrition decreased significantly with a subsequent decrease in duration of hospitalization. The highest percentage of patients showing normal findings of barium swallow and meal was among the two groups that received NAC (72.7% in Group II and 77.8% in Group IV). Group IV patients who received NAC and vitamin B complex had no esophageal strictures with improved outcomes. Conclusion: NAC and vitamin B complex enhanced recovery in the acute stage, in addition to prevention of delayed complications, especially esophageal strictures. Highlights: Acute corrosive ingestion is associated with high morbidity because of its catastrophic presentation and lifelong complications.This study was conducted on 92 patients admitted to Alexandria Poison Center (APC).IV NAC significantly decreased the time needed for starting oral intake after acute corrosive ingestion and consequently, the need for parenteral nutrition and duration of hospitalization.No patients suffered from esophageal strictures in the group which received both IV NAC and vitamin B complex.Both NAC and vitamin B complex improved the outcome of patients after ingestion of corrosives whether acids or alkalis.

Effect of caring leadership intervention program for first-line nurse managers on their managerial actions and nurse outcomes.

AIM: The aim of the study was to examine the effect of a caring leadership intervention program for first-line nurse managers (FLNM) on their caring knowledge and managerial actions as well as nurses' perceived FLNM caring behaviours and nurse outcomes. DESIGN: A quasi-experimental study design was implemented on two groups; study and control, including 30 FLNM and 150 nurses for each. METHODS: Self-report questionnaires about FLNMs' knowledge of caring behaviours and their managerial actions, nurses perceived line nurse managers' caring behaviours and nurses' outcomes (job satisfaction and work engagement) were utilized to collect study data from 1 July 2022 to 30 December 2022. RESULTS: A statistically significant difference and changes were revealed between the study and control groups in FLNMs' caring knowledge and their managerial actions, and nurses' perceived FLNMs' caring behaviours, nurses' job satisfaction and nurses' work engagement during post-test in comparison to pre-test. Higher total mean scores of post-test in the study group were recorded compared to those of control group regarding FLNMs' caring knowledge and their managerial actions as well as nurses 'perceived FLNMs' caring behaviour, job satisfaction and work engagement. CONCLUSION: The caring leadership intervention program for FLNMs was highly effective in enhancing their caring knowledge and managerial actions as well as nurses' perceived FLNM caring behaviours and nurse outcomes. IMPLICATIONS FOR THE PROFESSION: Caring leadership can help FLNMs to create a healthy environment, resulting in a positive outcome for nurse staff, patients and healthcare organizations. PATIENT AND PUBLIC CONTRIBUTION: No patient and public contribution.

Two case reports of fatal injuries sustained from tear gas guns loaded with pebbles as missiles.

These two case reports are of fatal injuries from less-lethal weapons (tear gas guns) using pebbles as an unconventional ammunition. Reported here are the fatal outcomes of two 19-year-old males, one with head trauma and the other with abdominal trauma. They were admitted to the ED and subjected to immediate exploratory operations, but they passed away. On autopsy, the first case demonstrated a right frontal bone fracture with subdural hemorrhage and a 3 × 2.5 cm pebble retained in the skull. The second case showed severe liver laceration in close vicinity to a cubical pebble (3.2 × 3 cm). The mechanical forces involved in skull fracture and autopsy are discussed. In the current cases, the relatively larger weight and size together with the surface configuration of the pebble projectile were the main influential factors that contributed to the severity of damage and fatality.These case reports are a working example of the effect of the mass of projectiles in increasing the power of penetration. The direct shooting to the head and the abdomen together with the misuse of these weapons are capable of inflicting fatal injuries.

Physicians' perspectives on different therapeutic approaches for aluminum phosphide poisoning and their relevant outcomes.

Background: Aluminum phosphide is a highly toxic pesticide that results in high mortality. To date, there is neither a definitive antidote nor a unified protocol for managing acute aluminum phosphide poisoning. Objectives: This cross-sectional questionnaire-based study aims to explore different management approaches and rely on the expertise of Egyptian medical professionals to enhance the prognosis for acute aluminum phosphide poisoning. Subjects and methods: A self-administered questionnaire was formulated and electronically distributed according to published literature and experience of senior physicians. Results and conclusions: Responses were received from 151 physicians from 10 governorates. Management modalities were variable among respondents. Noradrenaline was used by 90.7% of respondents with no fixed-dose regimen. In all, 84.1% of participants utilized oil in gastrointestinal decontamination; paraffin oil was the most used solution. Overall, 92.1, 61.6, 46.4, and 34.4% of participants used sodium bicarbonate, proton pump inhibitors, IV magnesium sulfate, and antioxidants, respectively. Regarding the frequency of acute aluminum phosphide poisoning, 47% of participants managed these cases daily or a few times a week. Participants' responses denoted a poor prognosis of acute aluminum phosphide poisoning, and high percentages attributed the prognosis to exposure factors rather than treatment modalities. Statistical analysis revealed that using oil in gastrointestinal decontamination improved the outcome by 4.62-fold. Clinical toxicologists were more likely to rescue ≥ 30% of the cases about 3-fold (2.97) than other specialties. Clinical toxicologists used oil in gastrointestinal decontamination, magnesium sulfate, and antioxidant therapy and calculated base deficit before administration of sodium bicarbonate by 7.70-, 5.30-, 3.26-, and 2.08-fold than other specialties.

Outbreak of foodborne botulism in Alexandria, Egypt: modulating indications for administration of heptavalent botulinum antitoxin.

In October 2019, ninety-four patients were admitted into Alexandria Poison Center (APC) with a history of ingestion of Feseekh (salted fish). In an attempt to allocate the resources, not all patients were given HBAT (botulism antitoxin heptavalent (A, B, C, D, E, F, G) equine immediately. The current study aimed to portray the clinical characteristics of the cases, explore the possible relation between these characteristics and necessity of HBAT administration, explore the reliability of mouse lethal test, and establish a clinical guide for management including preservation of resources. The current prospective study included 94 patients who were admitted to Alexandria Poison Center (APC) in the period from the 29th of September to the 27th of October 2019. The patients' data were recorded using a checklist that includes: personal data, past medical history, clinical assessment, investigations, treatment, and the outcome. The checklist was carried out to assess and follow up each patient. Hospitalized patients were categorized according to symptoms consistent with botulism. The equine HBAT, made by Emergent BioSolutions Canada Inc. (formerly Cangene Corporation), was used in the treatment. HBAT was given to thirty-four patients (36.2%) only out of the total admission. However, eighty-two (87.2%) of patients were completely cured, whereas ten patients (10.6%) were discharged with mild neurological sequels and death occurred only in two cases (2.2%). Sixty cases (63.8%) with suspected foodborne botulism could be managed by supportive treatment only with no need for HBAT, while patients with evident neurological signs received HBAT immediately.

Child maltreatment: knowledge, attitudes and reporting behaviour of physicians in teaching hospitals, Egypt.

BACKGROUND: Lack of diagnosis and reporting of child maltreatment are important problems worldwide. AIMS: This study aimed to assess the knowledge, attitude and practice of physicians in Alexandria University teaching hospitals about the diagnosis and reporting of child maltreatment cases. METHODS: A descriptive cross-sectional study was conducted at three hospitals. All physicians working regularly in emergency units were invited to complete a self-administered questionnaire. Data collected included sociodemographic characteristics, knowledge of and formal training on child maltreatment, attitude to dealing with child maltreatment, and experience of child maltreatment cases and reporting behaviour. RESULTS: A total of 90 physicians were included in the study. Only 11% correctly identified all the signs of child maltreatment and 29% correctly answered all questions on the social indicators of maltreatment. Only 41% of the participants had a good knowledge score (≥ 75%) on child maltreatment. Longer work experience (P = 0.019) and older age (P = 0.039) were associated with better knowledge. Of 249 suspected cases of child maltreatment that the physicians reported they had experienced, only 36% were reported. Formal training on child maltreatment (P < 0.001) and older age (P = 0.006) were associated with physicians' reporting behaviour. Over half (56%) of the participants thought their workplaces did not provide them with procedures to follow if they suspected child maltreatment. CONCLUSION: Physicians' knowledge of the signs and social indicators of child maltreatment was unsatisfactory. Clinical training and education are needed to improve their ability to diagnosis and report cases of child maltreatment.

Serial ultrasonographic monitoring of diaphragmatic and mid-upper arm muscle thickness in mechanically ventilated respiratory patients: A single-center observational study.

INTRODUCTION: Muscle monitoring during mechanical ventilation (MV) is gaining great interest nowadays; however, a proper monitoring tool is not well-established yet. OBJECTIVES: To assess the role of ultrasound in muscle monitoring during MV in respiratory patients. METHODS: Eligible 68 mechanically ventilated patients were consecutively enrolled. Serial ultrasound measurements of diaphragmatic thickness at the end of inspiration (Tdi) and mid-upper arm (MUA) muscle thickness were recorded every other day till weaning. Before discharge, functional status score (FSS) was assessed. RESULTS: Tdi decreased in 72.1%, did not change in 13.2% and increased in 14.7% of the patients. MUA muscle thickness decreased in 47.17% and did not change in others. Significant correlation between Tdi and MUA muscle thickness change was found (r = 0.404, P = 0.001); however, MUA muscle thickness change could not predict Tdi change (B = 0.067, P = 0.059). Diaphragmatic and MUA thickness change showed significant negative correlation with ICU stay (r = -0.260, -0.647, P = 0.032, <0.001) and MV duration (r = -0.335, -0.596, P = 0.005, <0.001), respectively. Weaning failure was significantly higher among patients with decreased Tdi (64.28%) and FSS was significantly lower in those with decreased MUA muscle thickness. US measurements of Tdi and MUA muscle thickness showed excellent intra-observer (ICC = 0.996, 0.999, P < 0.001) and inter-observer agreement (ICC = 0.992, 0.998, P < 0.001), respectively. CONCLUSION: Sonographic muscle monitoring during MV is promising. Changes in the diaphragmatic thickness during MV are common and weakly related to those of peripheral muscles. Early decreased muscle thickness heralds poor weaning and functional outcome.

Nursing workplace and its relation to occupational health outcomes and physical activity.

Background: Working in hospitals entails several risks to nurses. A better nursing workplace can help in improving physical activity and reducing adverse occupational health outcomes among nurses. Aim: This study aimed to investigate the relationships of the nursing workplace with occupational health outcomes and physical activity. Methods: A cross-sectional correlation study was conducted with 623 nurses. Data were collected through report self-administered questionnaires that included employment and occupational conditions, hospital workplace environment, and adverse occupational health outcomes as well as physical activity pattern. Results: The current study showed that the nursing workplace environment and conditions had a negative effect on occupational health outcomes and physical activity among nurses in the study units. Nurses in this study reported a high prevalence of low back pain (82.7%), burnout (78.3%), and occupational injuries (70.5%). They also reported insufficient physical activities (90.6%). High prevalence of burnout and low back pain were associated with low levels of physical activities among nurses. Conclusion: A fair working environment and conditions have been implicated as a causative factor of negative occupational health outcomes and limitations of physical activity among nurses. Adverse occupational health outcomes also affect the nurses engaging in physical activity.

A descriptive study of accidental skeletal injuries and non-accidental skeletal injuries of child maltreatment.

BACKGROUND: Lack of awareness and recognition of child maltreatment is the major reason behind underreporting. All victims often interact with the health care system for routine or emergency care. In several research works, non-accidental fractures are the second most common injury in maltreated children and it is represented up to one-third of cases. AIM OF THE STUDY: To determine the incidence of different types of accidental and non-accidental skeletal injuries among children, estimate the severity of injuries according to the modified injury severity score and to determine the degree of fractures either closed or opened (Gustiloe-Anderson open fracture classification). Moreover, identifying fractures resulting from child abuse and neglect. This aimed for early recognition of non-accidental nature of fractures in child maltreatment that can prevent further morbidity and mortality. PATIENTS AND METHOD: A descriptive study was carried out on all children (109) with skeletal injuries who were admitted to both Main Alexandria and El-Hadara Orthopedic and Traumatology University Hospitals during six months. History, physical examination and investigations were done for the patients. A detailed questionnaire was taken to diagnose child abuse and neglect. Gustiloe-Anderson open fracture classification was used to estimate the degree of open fractures. RESULTS: Out of 109 children, twelve cases (11%) were categorized as child maltreatment. One case was physical abuse, eight cases (7.3%) were child neglect and three cases (2.8%) were labour exploitation. Road traffic accidents (RTA) was the commonest cause of skeletal injuries followed by falling from height. Regarding falls, they included 4 cases of stair falls in neglected children and another four cases of falling from height (balcony/window). The remaining 36 cases of falls were accidental. The skeletal injuries were in the form of fractures in 99 cases, dislocation in two cases, both fracture and/or dislocation in three cases, and bone deformity from brachial plexus injury in five cases. Fractures of the lower limb (42.2%) and both bones of the forearm (35%) represented the highest incidence of skeletal injuries in children. 54.5% of fractures due to neglect were lower limb fractures due to falling from height. Ninety-nine cases were diagnosed as long bone fractures and classified as the following; eighty patients as closed fractures, six patients as open grade I fractures, three patients as open grade II fractures, three patients as open grade IIIA fractures, four patients as open grade IIIB fractures and three patients as open grade IIIC fractures. CONCLUSION AND RECOMMENDATION: Cases of neglect and child abuse represented 11% of all the studied cases, where neglect was the main cause. RTA and falling from height represented the most common cause of skeletal injury in children. Most fractures due to neglect were lower limb fractures resulting from falling from height. This demonstrates the need for early detection of neglect and child maltreatment aiming for early initiation of parental educational programs about child care and safety. Misinterpretation of skeletal injuries due to neglect or abuse can be avoided by proper training of orthopedic and traumatology staff on signs of child neglect and abuse.

Acute pulmonary thromboembolism in emergency room: gray-scale versus color doppler ultrasound evaluation.

BACKGROUND: Pulmonary thromboembolism (PTE) remains under-diagnosed fatal disease at emergency units suggesting the need for alternative, easy, and noninvasive bedside diagnostic approaches. OBJECTIVES: To determine the diagnostic role of gray-scale and color Doppler transthoracic ultrasonography (TUS) in patients with PTE. PATIENTS AND METHODS: Blinded to 64 multi-detectors CT pulmonary angiography (MDCTPA) examination as a gold standard, 60 patients with clinically suspected PTE underwent gray-scale and then color Doppler TUS examination. Results were compared and diagnostic accuracy of TUS was assessed. RESULTS: Forty patients proved to have PTE by MDCTPA. TUS showed typical lesions in 33 patients with the mean of 2 lesions per patient. Most lesions were hypoechoic, wedge- shaped, and pleural- based and the majority (80%) was located in the lower lobes. Consolidation with little perfusion was detected by Color Doppler ultrasound in 97% of lesions. Isolated central PTE was significantly higher in TUS negative patients. For gray -scale TUS, sensitivity, specificity, positive and negative predictive values and accuracy were 82%, 90%, 94%, 72%, and 85%. Meanwhile the sensitivity, specificity, positive and negative predictive values and accuracy of color Doppler TUS were 80%, 95%, 97%, 70% and 87%, respectively. CONCLUSION: TUS is a reliable diagnostic bedside test for PTE in critically ill and immobile patients. Adding color Doppler to gray-scale TUS increases the specificity and accuracy and consequently the confidence in the diagnosis of peripheral pulmonary infarctions and differentiates them from other pulmonary lesions that allow initiation of anticoagulants.

A Horned Viper Bite Victim with PRES.

Neurological complications of snake bites have been well documented in the literature as neuromuscular paralysis and cerebrovascular complications; posterior reversible encephalopathy syndrome was rarely described. A 23-year-old lady presented near full term of her pregnancy with a horned snake Cerastes cerastes bite; after successful delivery she started complaining of altered mental status and visual disturbance with ulceration over the site of the snake bite. On admission, the patient had Glasgow Coma Score of 12, blood pressure 130/80 mmHg, temperature 38°C, sinus tachycardia at 120 beats per minute, severe dehydration, and reduction in visual acuity to "hand motion" in both eyes with poor light projection and sluggish pupillary reactions. CT brain was not conclusive; MRI revealed features of PRES. Treatment was mostly supportive within one week; the patient regained consciousness; visual disturbance, however, persisted. This patient as well as the few previously described cases highlights PRES as a possible complication of snake bites.

Diagnostic value of ex vivo pleural fluid interferon-gamma versus adapted whole-blood quantiferon-TB gold in tube assays in tuberculous pleural effusion.

BACKGROUND: Noninvasive diagnosis of pleural tuberculosis (TB) remains a challenge due to the paucibacillary nature of the disease. As Mycobacterium tuberculosis (MTB)-specific T cells are recruited into pleural space in TB effusion; their indirect detection may provide useful clinical information. OBJECTIVES: Evaluation of pleural fluid interferon (INF)-γ levels vs Quantiferon-TB Gold In tube assay (QFT- IT) in blood and its adapted variants, using pleural fluid or isolated pleural fluid cells in the diagnosis of pleural TB. METHODS: Thirty-eight patients with pleural effusion of unknown etiology presented at Assiut University Hospital, Egypt, were recruited. Blood and pleural fluid were collected at presentation for INF-γ assays. Ex vivo pleural fluid INF-γ levels, QFT-IT in blood and its adapted variants were compared with final diagnosis as confirmed by other tools including blind and/or thoracoscopic pleural biopsy. RESULTS: The final clinical diagnosis was TB in 20 (53%), malignancy in 10 (26%), and effusion due to other causes in eight patients (21%). Ex vivo pleural fluid INF-γ levels accurately identified TB in all patients and were superior to the QFT-IT assays using blood or pleural fluid (70 and 78% sensitivity, with 60 and 83% specificity, respectively). QFT-IT assay applied to isolated pleural fluid cells had 100% sensitivity and 72% specificity. The optimal cut-off obtained with ROC analysis was 0.73 for TB Gold assay in blood assay, 0.82 IU/ml for the cultured pleural fluid assay, and 0.94 for isolated pleural cells assay. CONCLUSION: The ex vivo pleural fluid INF-γ level is an accurate marker for the diagnosis of pleural TB. QFT- IT assay in peripheral blood or its adapted versions of the assay using pleural fluid and/or washed pleural fluid cells had no diagnostic advantage over pleural fluid INF-γ in the diagnosis of pleural TB.

Home-based pulmonary rehabilitation program: Effect on exercise tolerance and quality of life in chronic obstructive pulmonary disease patients.

BACKGROUND: A key component in the management of chronic obstructive pulmonary disease (COPD) patients is pulmonary rehabilitation (PR), the corner stone of which is exercise training. AIM: This study aims to evaluate the effect of a two-months, home-based PR program with outpatient supervision every two weeks, on exercise tolerance and health-related quality of life (HRQL) using Arabic-translated standardized generic and specific questionnaires in COPD patients recently recovered from acute exacerbation, DESIGN: Randomized clinical trial. SETTING AND SUBJECTS: A total of 39 COPD patients who recovered from acute exacerbation were randomly allocated either a two-month home-based PR program in addition to standard medical therapy or standard medical therapy alone in the period between July 2008 and March 2009. METHODS: Pulmonary function tests (PFTs), six-minute walk distance (6-MWD) test, Arabic-translated chronic respiratory disease questionnaire-self administered standardized format (CRQ-SAS) and quality of life scale Short Form (SF-36) were compared between 25 patients with moderate to severe COPD who underwent a two-month PR program (group 1) and 14 COPD patients who did not (group 2). RESULTS: Group 1 showed significant improvement in the 6-MWD, and HRQL scores at two months compared with the usual care patients in group 2 (P less than 0.05). Improvement in both CRQ-SAS and SF-36 scores were statistically significant and comparable in group 1. CONCLUSION: The supervised, post discharge, two-month home-based PR program is an effective non pharmacological intervention in the management of stable patients with COPD. The 6-MWD is a simple, inexpensive and safe test to assess physical and functional capabilities among COPD patients. HRQL can be measured in patients with COPD either by disease-specific tools that have been specifically designed for use in patients with respiratory system disorders or by generic HRQL tools that can be used across populations with a variety of medical conditions. The Arabic-translated CRQ-SAS is a new tool for assessment of Arabic-speaking patients with chronic respiratory diseases.

Evaluation of recently validated non- invasive formula using basic lung functions as new screening tool for pulmonary hypertension in idiopathic pulmonary fibrosis patients.

BACKGROUND: A prediction formula for mean pulmonary artery pressure (MPAP) using standard lung function measurement has been recently validated to screen for pulmonary hypertension (PH) in idiopathic pulmonary fibrosis (IPF) patients. OBJECTIVE: To test the usefulness of this formula as a new non invasive screening tool for PH in IPF patients. Also, to study its correlation with patients' clinical data, pulmonary function tests, arterial blood gases (ABGs) and other commonly used screening methods for PH including electrocardiogram (ECG), chest X ray (CXR), trans-thoracic echocardiography (TTE) and computerized tomography pulmonary angiography (CTPA). MATERIALS AND METHODS: Cross-sectional study of 37 IPF patients from tertiary hospital. The accuracy of MPAP estimation was assessed by examining the correlation between the predicted MPAP using the formula and PH diagnosed by other screening tools and patients' clinical signs of PH. RESULTS: There was no statistically significant difference in the prediction of PH using cut off point of 21 or 25 mm Hg (P = 0.24). The formula-predicted MPAP greater than 25 mm Hg strongly correlated in the expected direction with O2 saturation (r = -0.95, P < 0.000), partial arterial O2tension (r = -0.71, P < 0.000), right ventricular systolic pressure measured by TTE (r = 0.6, P < 0.000) and hilar width on CXR (r = 0.31, P = 0.03). Chest symptoms, ECG and CTPA signs of PH poorly correlated with the same formula (P > 0.05). CONCLUSIONS: The prediction formula for MPAP using standard lung function measurements is a simple non invasive tool that can be used as TTE to screen for PH in IPF patients and select those who need right heart catheterization.
