Foreign Objects

Accidental swallowing of foreign bodies is a common problem among the pediatric population (6 months to 3 years), especially if the foreign body (FB) presents a sharp end that could potentially lead to perforation of the gastrointestinal (GI) tract, resulting in infection and complications. We report the case of a 2-year-old, admitted to the Emergency Department of our hospital after ingesting two FBs classifiable as sharp objects, specifically two metal nails, both approximately 4-cm long, which had been swallowed in one go, as reported by the parents. The patient had been previously admitted to another hospital in the same region, where the Emergency Department (ED) doctors took an X-ray to confirm the ingestion. The foreign bodies ingestion was thus confirmed, and they were, according to their report, located in the GI tract over the stomach. The patient has been monitored through all of his stay in the hospital and the progression of the foreign bodies has been documented with serial X-rays. Since neither clinical nor radiological signs of perforation were present, putting the FBs in the small bowel, a non-operative expectant management was followed. After 4 days of admission, the patient had passed one of the two FBS and later on the second one, without any complication. Thereafter the patient was discharged. The management of sharp gastrointestinal foreign objects ingestion is still debated, and the data of the current literature are poor. A number of case reports and small case series describe successful conservative management for the majority of ingested sharp objects. According to the literature data, our report confirms that the ingestion of sharp objects and relatively big objects in a baby can be successfully non-operatively managed, even despite the age of the patient and though the FBs are multiple.

The advantages of freeze substitution fixation over conventional chemical fixation for preservation of ultrastructural details in fungi have been discussed by various authors. As most ascomycetes, basidiomycetes and deuteromycetes do not fix well using conventional chemical fixation protocols, freeze substitution has attracted the attention of many individuals interested in fungal ultrastructure. Thus far most workers using this technique on fungi have concentrated on thin walled somatic hyphae. However, in our laboratory we have experimented with the use of freeze substitution on a variety of fungal reproductive structures and spores with promising results.Here we present data on freeze substituted samples of sporangia of the zygomycete Umbellopsis vinacea, basidia of Exobasidium camelliae var. gracilis, developing teliospores of the smut Sporisorium sorghi, germinating teliospores of the rust Gymnosporangium clavipes, germinating conidia of the deuteromycete Cercosporidium personatum, and developing ascospores of Ascodesmis nigricans.Spores of G. clavipes and C. personatum were deposited on moist pieces of sterile dialysis membrane where they hydrated and germinated. Asci of A. nigricans developed on pieces of dialysis membrane lying on nutrient agar plates. U. vinacea was cultured on small pieces of agar-coated wire. In the plant pathogens E. camelliae var. gracilis and S. sorghi, a razor blade was used to remove smal1 pieces of infected host issue. All samples were plunged directly into liquid propane and processed for study according to Hoch.l Samples on dialysis membrane were flat embedded. Serial thin sections were cut using a diamond knife, collected on slot grids, and allowed to dry down onto Formvar coated aluminum racks. Sections were post stained with uranyl acetate and lead citrate.

Although many electron microscopic studies on extracted chromatin have provided considerable information on chromatin condensation induced by divalent cations, there is only a little literature available on the effects of divalent cations on chromatin structure in intact nuclei. In the present study, the effects of Mg2+ on chromatin structure in isolated chicken liver nuclei were examined over a wide concentration range of Mg2+ by scanning electron microscopy.Nuclei were prepared from chicken liver by the method of Chauveau et al. with some modifications. The nuclei were suspended in 25 mM triethanolamine chloride buffer (pH7.4) with 1 mM EDTA or in the buffer with concentrations of MgCl2 varying from 1 to 50 mM. After incubation for 1 min at 0°C, glutaraldehyde was added to 1.8% and the nuclei were fixed for 1 h at 4°C. The fixed nuclei were mixed with 15% gelatin solution warmed at about 40°C, and kept at room temperature until the mixture set. The gelatin containing the nuclei was fixed with 2% glutaraldehyde for 2-4 h, and cut into small blocks. The gelatin blocks were conductive-stained with 2% tannic acid and 2% osmium tetroxide, dehydrated in a graded series of ethanol, and freeze-cracked with a razor blade in liquid nitrogen.

Efficacy Of Treatment

Abstract. Background: Previous suicide attempts increase the risk of a completed suicide. However, a large proportion of patients with deliberate self-wrist cutting (DSWC) are often discharged without undergoing a psychiatric interview. Aims: The aims of this study were to investigate the differences in the characteristics and outcomes of patients with DSWC and those with deliberate self-poisoning (DSP) episodes. The results of this study may be used to improve the efficacy of treatment for DSWC patients. Method: We retrospectively reviewed the medical records of 598 patients with DSWC and DSP who were treated at the emergency department of Seoul Saint Mary's Hospital between 2008 and 2013. We assessed sociodemographic information, clinical variables, the reasons for the suicide attempts, and the severity of the suicide attempts. Results: A total of 141 (23.6%) patients were included in the DSWC group, and 457 (76.4%) were included in the DSP group. A significantly greater number of patients in the DSWC group had previously attempted suicide (p = .014). A total of 63 patients (44.7%) in the DSWC group and 409 patients (89.5%) in the DSP group underwent psychiatric interviews. Conclusion: More DSWC patients had previously attempted suicide, but fewer of them underwent psychiatric interviews compared with the DSP patients.

Background: The international literature reports that for every completed suicide there are between 8 and 22 visits to an Emergency Department (ED) for attempted suicide/suicidal behavior. Aims: To describe the characteristics of admission to emergency departments (EDs) for suicide-related presenting complaints in the metropolitan area of Bologna; to estimate the risk for all-cause mortality and for suicide; to identify the profiles of subjects most at risk. Method: Follow-up of patients admitted to the EDs of the metropolitan area of Bologna between January 2004 and December 2010 for attempted suicide. A Cox model was used to evaluate the association between sociodemographic variables and the general mortality risk. Results: We identified 505 cases of attempted suicide, which were more frequent for female subjects, over the weekend, and at night (8:00 p.m./8:00 a.m.). The most used suicide methods were psychotropic drugs, sharp or blunt objects, and jumping from high places. In this cohort, 3.6% of subjects completed suicide (4.5% of males vs. 2.9% of females), 2.3% within 1 year of the start of follow-up. The most common causes of death were drug use and hanging. In the multivariate analysis, those who used illicit drugs 24 hr prior to admission to the ED (hazard ratio [HR] = 3.46, 95% CI = 1.23–9.73) and patients who refused the treatment (HR = 6.74, 95% CI = 1.86–24.40) showed an increased mortality risk for suicide. Conclusion: Deliberate self-harm patients presenting to the ED who refuse treatment represent a specific target group for setting up dedicated prevention schemes.
