Review
Infectious diseases such as norovirus can induce emesis (vomiting), which can be of a projectile nature. Although studies have been carried out on transmission, prevalence and decontamination of such micro-organisms within various environments, little is known about the extent to which the surrounding environment is contaminated when an individual vomits. This is an important consideration for infection control purposes. The aim of this study was to develop a simulated vomiting system (Vomiting Larry) to be used for assessing the extent to which projected fluid can contaminate the environment. Vomiting Larry was set up within a Controlled Atmosphere Chamber (CAC) facility at the Health and Safety Laboratory (HSL). Simulated vomiting was undertaken using water as a vomitus substitute containing a fluorescent marker enabling small splashes, ordinarily missed, to be visualised using UV lighting. Experiments revealed that splashes and droplets produced during an episode of projectile vomiting can travel great distances (>3 m forward spread and 2.6 m lateral spread). The research highlighted that small droplets can be hard to see and therefore cleaning all contaminated surfaces is difficult to achieve. Evidence from this study suggests that areas of at least 7.8 m should be decontaminated following an episode of projectile vomiting.

OBJECTIVE
To report a case and review literature of bowel metastases from cervical squamous cell carcinoma.
CASE REPORT
A 49-year-old woman with a history of FIGO 2013 stage IVB cervical squamous cell carcinoma presented with refractory nausea, projectile vomiting, anorexia, postprandial abdominal pain, and significant weight loss for six months. Restaging images didn't reveal viable tumors but thickened duodenal wall indicating gastric outlet obstruction. Initially, the etiology was masked by chronic erosive duodenitis and mistreated as a duodenal ulcer. After repeated gastrointestinal endoscopic biopsy confirming intramural duodenal metastasis from cervical squamous cell carcinoma, the patient was treated successfully by gastrojejunostomy and adjuvant chemotherapy. She has remained asymptomatic and disease-free for more than 12 months since the surgical metastasectomy.
CONCLUSION
Intestine metastasis from cervical cancer is a rare cause that may present as projectile vomiting due to gastric outlet obstruction. Prompt recognition and surgical intervention may provide good outcomes despite the metastatic nature.

Review
Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated food allergy presenting with delayed onset of projectile vomiting in the absence of cutaneous and respiratory symptoms. The pathophysiology of FPIES remains poorly characterized. The first international consensus guidelines for FPIES were published in 2017 and provided clinicians with parameters on the diagnosis and treatment of FPIES. The guidelines have served as a resource in the recognition and management of FPIES, contributing to an increased awareness of FPIES. Since then, new evidence has emerged, shedding light on adult-onset FPIES, the different phenotypes of FPIES, the recognition of new food triggers, center-specific food challenge protocols and management of acute FPIES. Emerging evidence indicates that FPIES impacts both pediatric and adult population. As a result, there is growing need to tailor the consensus guidelines to capture diagnoses in both patient groups. Furthermore, it is crucial to provide food challenge protocols that meet the needs of both pediatric and adult FPIES patients, as well as the subset of patients with atypical FPIES. This review highlights the evolving clinical evidence relating to FPIES diagnosis and management published since the 2017 International FPIES Guidelines. We will focus on areas where recent published evidence may support evolution or revision of the guidelines.

Meta-Analysis Review
BACKGROUND
Traumatic hyphema is the entry of blood into the anterior chamber (the space between the cornea and iris) subsequent to a blow or a projectile striking the eye. Hyphema uncommonly causes permanent loss of vision. Associated trauma (e.g. corneal staining, traumatic cataract, angle recession glaucoma, optic atrophy, etc.) may seriously affect vision. Such complications may lead to permanent impairment of vision. Patients with sickle cell trait/disease may be particularly susceptible to increases of elevated intraocular pressure. If rebleeding occurs, the rates and severity of complications increase.
OBJECTIVES
To assess the effectiveness of various medical interventions in the management of traumatic hyphema.
SEARCH METHODS
We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 8), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to August 2013), EMBASE (January 1980 to August 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 30 August 2013.
SELECTION CRITERIA
Two authors independently assessed the titles and abstracts of all reports identified by the electronic and manual searches. In this review, we included randomized and quasi-randomized trials that compared various medical interventions versus other medical interventions or control groups for the treatment of traumatic hyphema following closed globe trauma. We applied no restrictions regarding age, gender, severity of the closed globe trauma, or level of visual acuity at the time of enrolment.
DATA COLLECTION AND ANALYSIS
Two authors independently extracted the data for the primary and secondary outcomes. We entered and analyzed data using Review Manager 5. We performed meta-analyses using a fixed-effect model and reported dichotomous outcomes as odds ratios and continuous outcomes as mean differences.
MAIN RESULTS
We included 20 randomized and seven quasi-randomized studies with 2643 participants in this review. Interventions included antifibrinolytic agents (oral and systemic aminocaproic acid, tranexamic acid, and aminomethylbenzoic acid), corticosteroids (systemic and topical), cycloplegics, miotics, aspirin, conjugated estrogens, traditional Chinese medicine, monocular versus bilateral patching, elevation of the head, and bed rest. No intervention had a significant effect on visual acuity whether measured at two weeks or less after the trauma or at longer time periods. The number of days for the primary hyphema to resolve appeared to be longer with the use of aminocaproic acid compared with no use, but was not altered by any other intervention.Systemic aminocaproic acid reduced the rate of recurrent hemorrhage (odds ratio (OR) 0.25, 95% confidence interval (CI) 0.11 to 0.57), but a sensitivity analysis omitting studies not using an intention-to-treat (ITT) analysis reduced the strength of the evidence (OR 0.41, 95% CI 0.16 to 1.09). We obtained similar results for topical aminocaproic acid (OR 0.42, 95% CI 0.16 to 1.10). We found tranexamic acid had a significant effect in reducing the rate of secondary hemorrhage (OR 0.25, 95% CI 0.13 to 0.49), as did aminomethylbenzoic acid as reported in one study (OR 0.07, 95% CI 0.01 to 0.32). The evidence to support an associated reduction in the risk of complications from secondary hemorrhage (i.e. corneal bloodstaining, peripheral anterior synechiae, elevated intraocular pressure, and development of optic atrophy) by antifibrinolytics was limited by the small number of these events. Use of aminocaproic acid was associated with increased nausea, vomiting, and other adverse events compared with placebo. We found no difference in the number of adverse events with the use of systemic versus topical aminocaproic acid or with standard versus lower drug dose. The available evidence on usage of corticosteroids, cycloplegics, or aspirin in traumatic hyphema was limited due to the small numbers of participants and events in the trials.We found no difference in effect between a single versus binocular patch or ambulation versus complete bed rest on the risk of secondary hemorrhage or time to rebleed.
AUTHORS' CONCLUSIONS
Traumatic hyphema in the absence of other intraocular injuries uncommonly leads to permanent loss of vision. Complications resulting from secondary hemorrhage could lead to permanent impairment of vision, especially in patients with sickle cell trait/disease. We found no evidence to show an effect on visual acuity by any of the interventions evaluated in this review. Although evidence was limited, it appears that patients with traumatic hyphema who receive aminocaproic acid or tranexamic acid are less likely to experience secondary hemorrhaging. However, hyphema in patients treated with aminocaproic acid take longer to clear.Other than the possible benefits of antifibrinolytic usage to reduce the rate of secondary hemorrhage, the decision to use corticosteroids, cycloplegics, or nondrug interventions (such as binocular patching, bed rest, or head elevation) should remain individualized because no solid scientific evidence supports a benefit. As these multiple interventions are rarely used in isolation, further research to assess the additive effect of these interventions might be of value.

Hypertrophic pyloric stenosis, a relatively common condition, is caused by hyperplasia of the musculature of the pylorus. The diagnosis is made by a history of projectile vomiting and failure to gain weight, the observation of gastric peristaltic waves, and the palpation of a pyloric “tumor.” A method of palpating this tumor is described in detail. Roentgenological studies are rarely indicated. Pylorotomy for treatment of hypertrophic pyloric stenosis was not successful until the development of necessary supporting measures. Preparation for operation consists of intravenous administration of fluids and electrolytes and sometimes serum or whole blood. The position of the tumor governs the choice between two different incisions. The operative procedure herein described is essentially that devised by Ramstedt many years ago, with modifications to facilitate the procedure.

UNLABELLED
Neonatal liver abscess is a rare condition with a high mortality rate. However, in a low-resource setting, high clinical vigilance and the use of readily accessible diagnostic modalities can help in early diagnosis and, along with appropriate medical management, prevent lethal complication.
CASE PRESENTATION
We present the case of a patient who presented with one day of sudden abdominal distension and two episodes of projectile nonbilious vomiting. A solitary liver abscess was diagnosed using ultrasonography and contrast-enhanced computed tomography findings, and the patient was treated conservatively with parenteral broad-spectrum antibiotics. Following the completion of the antibiotic dose, an ultrasound of the abdomen reveals that the size of the liver abscess has decreased.
CLINICAL DISCUSSION
Neonatal liver abscess is a rare clinical condition that causes significant morbidity and mortality in premature and term babies. In a neonate with potential risk factors, a high index of suspicion is required to make the diagnosis. Baseline tests, as well as computed tomography with or without contrast, aid in the definitive diagnosis of a hepatic abscess. For management, a multidisciplinary approach should be considered, including correction of the predisposing factor as well as appropriate medical and/or surgical intervention.
CONCLUSION
Neonatal liver abscess is frequently overlooked due to its rarity. Thus, whenever a neonate exhibits the aforementioned clinical spectrum, it should be considered in the differential diagnosis, and a diagnostic workup and treatment should be initiated as soon as possible to avoid debilitating complications.

BACKGROUND
Vomiting is one way in which the body rids itself of harmful gastric contents rapidly. Whilst this process is generally beneficial for the emetic individual, it can pose significant infection control issues if they are infected with a highly communicable pathogen such as norovirus. It is not known how far norovirus could spread through vomiting while remaining viable, particularly in far-reaching droplets and splashes that might be missed during cleaning.
AIM
To identify the potential level of dissemination of viable norovirus after simulated vomiting.
METHODS
This study used a system called 'Vomiting Larry' to simulate vomiting with infection medium containing the norovirus surrogate feline calicivirus (FCV) as a worst-case scenario for distribution and survival of viruses after simulated vomiting. Air and floor samples were taken after simulated vomiting, and analysed for viable virus via plaque assay. Analysis of covariance investigated differences in FCV concentration by sample volume and location.
FINDINGS
Whilst viable virus was not isolated from any air samples taken after simulated vomiting, FCV concentrations of ≥10 plaque-forming units/mL were recovered from almost all samples taken from the floor (88/90). These included small droplets of fluid that travelled 3 m away from the vomiting system. There was evidence that FCV concentration depended on both sample volume and location.
CONCLUSION
This study suggests that norovirus can survive being ejected even within small far-reaching droplets at concentrations capable of eliciting infection. Such droplets could easily go unnoticed and be overlooked during cleaning, adding to the challenge of controlling norovirus outbreaks.

BACKGROUND
Severe headaches, projectile vomiting, focal neurological deficits and early onset seizure are regarded as early warning symptoms of subarachnoid hemorrhage (SAH). Earlier diagnosis based on such warning symptoms theoretically would improve the clinical prognosis. However, it is still not clear whether the prognosis is correlated with early warning symptoms. Here, we reviewed warning symptoms and other predictive factors in the emergency room (ER) setting and examined their correlations with mortality.
METHODS
Ninety saccular aneurysmal SAH cases were reviewed in a single medical center between January 2011 and December 2013. We examined differences in mortality rate related to warning symptoms, SAH scales, onset-to-ER time, hydrocephalus, and aneurysm size, location, and complexity. Logistic regression analyses were performed to determine the correlations of warning symptoms and other predictive factors with mortality. Receiver operating characteristic (ROC) curve analysis was used to calculate the area the under curve (AUC) of SAH mortality prediction tools.
RESULTS
Warning headache, projectile vomiting, the Hunt and Hess scale, Fisher scale, World Federation of Neurological Surgeons (WFNS) grading scale, and modified WFNS (m-WFNS) scale, body mass index, aneurysm complexity and hydrocephalus were significantly different between the survivors and the decedents. The warning headache and WFNS grade were strongly correlated with mortality. The rate of prognostic prediction improved from 90.4% to 94.6% when warning headache was additionally evaluated.
CONCLUSIONS
With growing healthcare costs and recognition of the value of palliative care, early identification via warning headache and a detailed clinical history review is necessary for cases of aSAH.
