Favorable evolution of severe paraquat poisoning. Treatment with gastric lavage, activated charcoal, cyclophosphamide + corticoids, and conventional daily hemodialysis: case study at the Franck Joly Hospital Center in French Guiana / Évolution favorable d'une intoxication grave au paraquat. Traitement par lavage gastrique, charbon activé, cyclophosphamide + corticoïdes, et hémodialyse conventionnelle quotidienne : étude des cas au centre hospitalier Franck Joly en Guyane française

We report the observations of two patients, having voluntarily ingested lethal doses of paraquat with suicidal intent, with an unfavorable prognostic score. The treatment consisted of gastric lavage, administration of activated charcoal, n-acetylcysteine and cyclophosphamide + methylprednisolone + dexamethasone. The installation of acute renal failure motivated the initiation of daily conventional hemodialysis (HD) over 10 to 14 days, with a favorable evolution. The following complications were recorded: anemia, bacteremia and deep vein thrombosis. These observations raise three questions in the treatment of paraquat intoxication: the effectiveness of HD, the interest of its association with the above therapies in the prevention of pulmonary fibrosis, and the need for infectious prevention and thromboembolism. Furthermore, the absence of a paraquatemia assay cannot constitute a limitation for management, and hemoperfusion on an inaccessible charcoal column can be replaced by an HD usually available.

Nous rapportons les observations de deux patients ayant ingéré volontairement des doses létales du paraquat à but suicidaire, avec un score pronostic défavorable. Le traitement a consisté en un lavage gastrique, une administration du charbon activé, du n-acétylcystéine et du cyclophosphamide + méthylprednisolone + dexaméthasone. L'installation d'une insuffisance rénale aiguë a motivé l'initiation d'une hémodialyse conventionnelle quotidienne (HD) sur 10 à 14 jours, avec une évolution favorable. Les complications suivantes ont été enregistrées : anémie, bactériémie et thrombose veineuse profonde. Ces observations soulèvent trois questions dans le traitement d'une intoxication au paraquat : l'efficacité de l'HD, l'intérêt de son association avec les thérapeutiques supra dans la prévention de la fibrose pulmonaire, et la nécessité d'une prévention infectieuse et thrombo-embolique. Par ailleurs, l'absence d'un dosage de la paraquatémie ne peut constituer une limite pour la prise en charge, et l'hémoperfusion sur colonne de charbon non accessible peut être remplacée par une HD habituellement disponible.

Comparison of gastric lavage/sputum and stool specimens in the diagnosis of pediatric pulmonary tuberculosis- A pilot study.

BACKGROUND AND OBJECTIVE: Global TB report 2021 mentions 11 % prevalence of pediatric TB, whereas 5.65% of the cases were reported from India in 2020. India features in the list of TB high burden countries, HIV-TB high burden and MDR-TB high burden countries. The diagnosis of pulmonary tuberculosis in children is difficult as they tend to swallow the sputum, invasive techniques of gastric aspirates needs to be followed and the disease itself is paucibacillary. The disease progresses rapidly in young children and hence rapid diagnosis is needed. Obtaining appropriate respiratory samples for diagnosis is difficult especially in primary care settings. Stool sample is easy to obtain and since children swallow sputum, it can be used to diagnose pulmonary tuberculosis. With this background, a pilot study was planned to evaluate the accuracy of the Xpert MTB/RIF assay for the detection of MTB in stool specimens obtained from pediatric pulmonary TB patients confirmed either by gastric lavage(GL) or sputum(SP) Xpert MTB/RIF assay. In addition, the results of microscopy of stool specimen were compared with that of gastric lavage/ sputum (GL/SP) specimen by Ziehl-Neelsen (ZN) and fluorescent light-emitting diode (LED) staining. MATERIAL AND METHODS: A prospective study was carried out on 50 GL/SP Xpert MTB/RIF assay positive children (0-14 years). Stool specimens from these children were processed for Xpert MTB/RIF assay. The GL/SP and stool specimens were processed for ZN and Auramine O fluorescent microscopy as well. RESULTS: Fluorescent staining detected acid fast bacilli (AFB) in 24 GL/SP and 16 stool specimens as compared to 20 GL/SP and 10 stool specimens by ZN staining. Stool Xpert MTB/ RIF assay was positive in 29 out of 50 children. Rifampicin resistance was detected in 13 of the 50 (26%) GL/SP specimens. Of these 13 children, rifampicin resistance was detected in 7 stool specimens, rifampicin indeterminate resistance was detected in one specimen and in the remaining 5 children, M.tuberculosis was not detected in stool. CONCLUSION: Stool is a good non-invasive specimen for the detection of pulmonary TB in children, especially in remote areas, where invasive techniques cannot be performed for sample collection.

Research on Flow Traceability Technology of Medical Electric Gastric Lavage Machine.

The calibration method of the electric gastric lavage machine was developed for the two-way unsteady liquid flow measurement modeland the detection device of the medical electric gastric lavage machine was developed , which flow value can be traced to the quality and time. The experimental results showed that the flow measurement range of the detection device was (50∼3000) mL/min, and the pressure measurement range was (-60∼90) kPa, and the metrological performance of the detection device verified using an active piston type flow standard device can meet the traceability requirements of the key parameters of the medical electric gastric lavage machine.

Benefits and harms of gastric suction or lavage at birth for gastrointestinal outcomes: A systematic review and meta-analysis.

The benefits of routine gastric suctioning or lavage in neonates remain uncertain, despite the common practice worldwide. To investigate the potential advantages and harms, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) examining the effects of these procedures in healthy or meconium-stained neonates at birth. We systematically searched PubMed, Scopus, Embase, Ovid, and the Cochrane Library databases from inception to February 9, 2023. We included only RCTs assessing the outcomes of gastric suction or lavage in neonates at birth. We calculated risk ratio (RR) and weighted mean differences with 95% confidence intervals (CIs) using a random-effects model. The primary outcomes were gastrointestinal symptoms including vomiting, retching, feeding intolerance, and secondary aspiration. The secondary outcomes included time to initiation of breastfeeding and potential adverse procedure-related events. Twelve RCTs with a total of 4,122 neonates were analyzed. All the studies compared neonates who received gastric suction or lavage with those who received usual care. Gastrointestinal symptoms were significantly reduced in neonates receiving gastric suction or gastric lavage compared with the control group (RR, 0.75; 95% CI, 0.63-0.89). Gastric lavage was beneficial for infants with meconium-stained amniotic fluid (RR 0.71; 95% CI, 0.60-0.84), while gastric suction had no significant benefit in reducing gastrointestinal symptoms in infants without meconium-stained amniotic fluid (RR 0.91; 95% CI, 0.61-1.37). Our findings suggest that gastric suction or lavage may reduce gastrointestinal symptoms in neonates; however, these procedures may only benefit infants born with meconium-stained amniotic fluid. Vigorous newborns without meconium-stained amniotic fluid may not benefit from these procedures. Furthermore, gastric suction may lead to adverse outcomes such as apnea and bradycardia. Registration: This study was registered in the PROSPERO International prospective register of systematic reviews in health and social care (CRD42023247780).

Impact of Delivery Room Gastric Lavage on Exclusive Breastfeeding Rates Among Neonates Born Through Meconium-Stained Amniotic Fluid: A Randomized Controlled Trial.

BACKGROUND: Delivery-room gastric lavage reduces feeding intolerance and respiratory distress in neonates born through meconium-stained amniotic fluid (MSAF). OBJECTIVES: To evaluate the effects of gastric lavage on exclusive breastfeeding and skin-to-skin contact in neonates delivered through MSAF. DESIGN: Randomized controlled trial. PARTICIPANTS: 110 late preterm and term neonates delivered through MSAF not requiring resuscitation beyond initial steps. METHODS: Participants randomized into gastric lavage (GL) (n=55) and no-GL (n=55) groups. The primary outcome was the rate of exclusive breastfeeding at 72±12 hours of life. Secondary outcomes were time to initiate breastfeeding and establish exclusive breastfeeding, rate of exclusive breastfeeding at discharge, time to initiate skin-to-skin contact and its duration, rates of respiratory distress, feeding intolerance, and the procedure-related complications of gastric lavage monitored by pulse oximetry and videography. RESULTS: Both the groups were similar in baseline characteristics. 49 (89.1%) neonates in GL group could achieve exclusive breast-feeding at 72 hours compared to 48 (87.3%) in no-GL group [RR (95% CI) 1.02 (0.89-1.17); P=0.768]. Initiation of skin-to-skin contact was significantly delayed and the total duration was significantly less in GL group compared to no-GL group. No difference in respi-ratory distress and feeding intolerance was observed. Procedure-related complications included retching, vomiting, and mild desaturation. CONCLUSION: Gastric lavage did not help to establish exclusive breastfeeding, delayed the initiation of skin-to-skin contact in delivery room and reduced its total duration. Moreover, the procedure of gastric lavage was associated with neonatal discomfort.

Pharmacobezoar after overdose of isoniazid and rifampin.

In clinical toxicology, gastric endoscopic decontamination is rarely used, and only a few cases of pharmacobezoar removal after intentional ingestion of slow-release drugs have been described. Our case describes the use of gastric endoscopic decontamination to remove potential pharmacobezoar in an adolescent after ingestion of a lethal dose of isoniazid and rifampin, even long after gastric lavage. This technique allowed the removal of pharmacobezoars still present in the stomach while preventing further deterioration of the patient.

[Suicide attempts with castor beans and jequirity beans]. / Tentamen suicidii met wonderbonen en paternosterbonen.

BACKGROUND: Intoxications by beans can have serious consequences. We describe 2 auto-intoxications using castor beans and jequirity beans with the toxins ricin and abrin, respectively. Both toxins have similar mechanisms of action. When taken orally, a toxic mucositis develops causing dehydration, gastrointestinal blood loss and multi-organ failure. Knowledge about pathophysiology is important for risk assessment and treatment. CASE DESCRIPTION: Patient A presented 27 hours after ingestion of the castor beans with frequent vomiting and watery diarrhea. Patient B presented 45 minutes after ingestion of jequirity beans without physical complaints. Gastric lavage and bowel lavage was started. The clinical course in both patients was mild. The severity of toxicity depends on how much the beans have been chewed and the amount of ricin/abrin per bean. CONCLUSION: Intoxications with ricin or abrin can be potentially serious. There is no antidote. Treatment consists of anti-absorptive measures and best supportive care.

Successful treatment of ivermectin overdose in a bearded dragon (Pogona vitticeps) using gastric lavage and intravenous lipid emulsion.

OBJECTIVE: To describe the clinical signs and outcome following ivermectin overdose in a bearded dragon. This case also describes the novel use of intravenous lipid emulsion (ILE) as a rescue therapy in reptiles, as well as the use of aggressive gastrointestinal decontamination. CASE SUMMARY: A 4-year-old female intact bearded dragon (Pogona vitticeps) (0.6 kg) was admitted to the ICU at a specialty hospital following accidental overdose of 40 mg (66.7 mg/kg) of ivermectin enterally. The patient was physically inverted to allow passive reflux of the medication, then sedated for gastric lavage. A 20% ILE was administered intravenously due to the high risk for fatality. Additional treatments included 2 doses of activated charcoal, as well as SC fluids, enteral nutrition, and sucralfate. The patient was profoundly sedate until day 4 when mild improvements in mentation were noted. The patient started ambulating on its own on day 6 and was discharged from the hospital on day 13. The patient was alive 720 days postdischarge. NEW OR UNIQUE INFORMATION PROVIDED: This is the first case report describing the events following ivermectin overdose and the use of ILE therapy and activated charcoal in a bearded dragon. These therapies were tolerated with no adverse effects noted in this patient. This report provides evidence that complete recovery from ivermectin overdose is possible.

Severe caffeine poisoning successfully treated with high flow continuous hemodialysis.

In recent years, severe or lethal cases of caffeine poisoning after large or massive ingestion of caffeinated tablets have increased in Japan. Here we report the case of a 23-year-old male who ingested high-dose caffeine tablets (total: 32.4 g caffeine) in a suicide attempt. He was transferred to our hospital about 2 h after ingesting the tablets and presented with repeated vomiting and tremor in the trunk and extremities. His respiratory rate was 40 breaths/min, heart rate 240 beats/min, blood pressure 109/77 mmHg, and Glasgow Coma Scale E3V2M5. Blood tests revealed metabolic acidosis compensated with respiratory alkalosis, hyperlactatemia, hypokalemia, hyperglycemia, and leukocytosis. After tracheal intubation, gastric lavage was performed and activated charcoal was administered. The patient gradually became hypotensive (systolic blood pressure < 90 mmHg) with a heart rate > 250 beats/min, and non-sustained ventricular tachycardia frequently occurred. Given the lack of response to intravenous noradrenaline and landiolol, high flow continuous hemodialysis (CHD) was initiated 4 h after tablet ingestion with a blood flow rate of 150 mL/min and dialysate flow rate of 2000 mL/h. This dramatically improved his clinical signs and symptoms, especially during the first 3 h. His serum caffeine concentration was 240.9 µg/mL on admission and 344.0 µg/mL at the initiation of high flow CHD, but rapidly decreased to 153.8 µg/mL 3 h after initiating high flow CHD. Our findings suggest that high flow CHD may be effective in treating cases of severe caffeine poisoning with hemodynamics too unstable for intermittent hemodialysis.

Perfil epidemiológico de pacientes intoxicados con acetaminofén con intenciones suicidas / Epidemiological profile of patients intoxicated with acetaminophen for suicidal purposes / Perfil epidemiológico de pacientes intoxicados com acetaminofen (Paracetamol) com intenções suicidas

Objetivo: este estudio busca describir los individuos evaluados por sobredosis de acetaminofén entre 2019 y 2020 en un centro de referencia de trasplante hepático en Colombia. Metodología: estudio derivado del análisis secundario de historias clínicas entre el 1.º de enero de 2019 y el 31 de diciembre de 2020. Los criterios de inclusión abarcan individuos con ingestión aguda y voluntaria de dosis tóxicas de acetaminofén (>4 g/día). Resultados: sesenta y tres casos, 68% mujeres, 67% menores de 18 años y 54% estudiantes. Reportó historia personal de enfermedad psiquiátrica el 60% y el 35% al menos un intento de suicidio previo. La mediana de dosis de acetaminofén fue 15g, 46% refirieron co-ingesta de otras sustancias y 13% estaba bajo efecto de sustancias psicoactivas. El 57% tenía la intención clara de suicidarse, así como 81% vomitó antes de acudir al servicio de urgencias, 22% recibió medidas de descontaminación y 10% no recibió N - acetilcisteína. Quince individuos desarrollaron lesión hepática aguda, nueve con criterios de severidad. Conclusiones: la población era predominantemente joven, la historia de enfermedad psiquiátrica fue muy prevalente y la mayoría refirieron un evento vital que explicara el comportamiento impulsivo de consumo. Ninguno desarrolló criterios para trasplante hepático, lo cual podría explicarse por la edad de los individuos, los episodios de vómito temprano, y la ausencia de enfermedad hepática crónica o de consumo de sustancias hepatotóxicas.

Objective: this study aims to describe patients with overdose intake of acetaminophen between 2019 and 2020 at a reference center for liver transplantation in Colombia. Methodology: study derived from a secondary analysis of the clinical records between January 1st, 2019, to December 31st, 2020. Inclusion criteria were individuals with voluntary acute ingestion of toxic doses of acetaminophen (>4 g/day). Results: sixty-three cases, 68% women, 67% <18-year-old, and 54% students. 60% had personal history of psychiatric illness and 35% reported at least one previous suicide attempt. The median dose of acetaminophen was 15g, 46% referred to co-ingestion with other substances and 13% were under the effect of any psychoactive substance. 57% had a clear intention of suicide. 81% vomited before the arrival to the emergency room, 22% received decontamination intervention with gastric lavage or activated charcoal, and 10% did not receive any dose of N-Acetylcysteine. Fifteen individuals developed an acute liver injury, nine with severity criteria. Conclusions: the population was predominantly young, the personal history of psychiatric disease was highly prevalent, and most of the cases referred a vital event that explains the impulsive behavior in acetaminophen consumption. None developed criteria for liver transplantation, and this could be explained by the young age of the individuals, the episodes of early vomiting, and the absence of chronic liver disease or hepatotoxic substance consumption.

Potential role of paraffin oil gastric lavage in acute aluminum phosphide poisoning: a randomized controlled trial.

Aluminum phosphide (ALP) poisoning is a true medical emergency associated with high mortality. The lack of a specific antidote for ALP poisoning mandates searching for new treatment modalities. This study aimed to evaluate the effectiveness and safety of gastric decontamination by paraffin oil in cases with acute ALP poisoning. This study was a randomized, controlled, parallel-group, single-blind, phase II clinical trial conducted over a period of 6 months. Sixty-two patients with acute ALP poisoning were randomly allocated into two equivalent groups. In both groups, the standard ALP treatment was given. Gastric decontamination in the control group was performed by saline and sodium bicarbonate 8.4%, while in the intervention group, it was done by paraffin oil and sodium bicarbonate 8.4%. All patients were subjected to history taking, clinical examination, and laboratory investigations. The outcomes were evaluated. The median age of the studied patients was 20 years. Most of the studied cases were females, single, and from rural areas. The median delay time was 1 h. All patients included in the study alleged ingestion of ALP during suicidal attempts. Twelve hours after admission, many clinical and laboratory findings were significantly better in the intervention group. The need for intubation, mechanical ventilation, and total amount of vasopressors was significantly lower, and the mortality rate was non-significantly lower in the intervention group compared to the control. The median length of hospital stay was significantly shorter in the control group. Gastric decontamination with paraffin oil and sodium bicarbonate 8.4% could be valuable in reducing ALP poisoning severity, the need for intubation, mechanical ventilation, and vasopressors.

[A design of anti-reflux gastric lavage tube with built-in airbag].

At present, the gastric lavage tube used in clinical practice only has a few liquid orifices at the distal end of the lumen, and its structure has defects such as residual liquid reflux and aspiration in clinical practice. This article aims to solve the shortcomings of the existing technology and design a gastric lavage tube with built-in airbag with reasonable structure and high safety, in order to optimize the design and apply it to the actual clinical work, and further reduce the complications caused by the gastric lavage tube.

Common bacteria in sputum or gastric lavage of patients presenting with signs and symptoms of lower respiratory tract infections.

INTRODUCTION: lower respiratory tract infections (LRTIs) are infections involving the trachea, primary bronchi and lungs. People with LRTIs typically experience coughs as the primary symptoms; however, shortness of breath, weakness, fever and fatigue may be coupled with the cough. It is common among the aged, children under five and the immune-suppressed. Persons with symptoms suggestive of pulmonary tuberculosis (TB) may have tuberculosis, other respiratory tract infection or co-infection of tuberculosis and other respiratory pathogens. This study aimed to identify the presence of pathogens in sputum of suspected tuberculosis cases and their antimicrobial resistance patterns. METHODS: this was a retrospective study conducted from September 2018 to November 2019 at Tamale Public Health Laboratory. Sputum or gastric lavage samples were collected from persons with suspected clinical presentations of TB and/or LRTI. These samples were cultured using standard microbiological protocols and antimicrobial susceptibility test performed on the positive cultures by Kirby-Bauer disc diffusion method. Molecular identification of M. tuberculosis was performed on all the suspected TB cases using GeneXpert mycobacterium tuberculosis/rifampin (MTB/RIF) assay. RESULTS: during the study period, there were 264 cases of which 49.2% were males and 50.8% were females. Positive cases for culture were 47.3%. Out of the 264 cases, 186 (70.5%) were suspected TB with 51.6% being positive for culture, 6.5% positive for M. tuberculosis (GeneXpert confirmed) and 3.8% co-infection of TB with other bacteria pathogens. Klebsiella spp. (35/125; 28%) and Pseudomonas spp. (19/125; 15.2%) were the most predominant pathogens isolated. There was no significant difference in detection of bacteria in males and females (p=0.89), however individuals with suspected TB were significantly infected with other bacterial species than the unsuspected individuals (p=0.03). Almost all the isolates showed high susceptibility towards carbapenem (meropenem) and high resistance towards the third generation cephalosporins (cefotaxime and ceftriaxone). CONCLUSION: this study highlights the need to test individuals with classical symptoms of LRTIs for other bacterial infections other than TB only. Sputum culture is recommended for all suspected tuberculosis cases to provide accurate laboratory diagnosis to LRTIs and mitigate unnecessary use of antimicrobials.

[Four cases of acute diquat poisoning with prominent epileptoid seizure and literature review].

Objective: To further improve the awareness of the clinical feature of acute diquat poisoning. Methods: A retrospective analysis was performed on 4 cases of acute diquat poisoning with epileptoid seizure as the main clinical manifestation, which were admitted and diagnosed by the Characteristic Medical Center of Chinese People's Armed Police Force from January 1, 2017 to December 31, 2019. Take "Diquat" or "Deiquat" or "Reward" as keyword search for CNKI, Pubmed, and EMbase in both Chinese and English. The date of literature retrieval was from the database founding to December 31, 2019. Results: Of the 4 patients, 3 were male and 1 female, with an average age of 28 years (22-33 years) . The estimated dose was 8-20 g. All patients were treated with gastric lavage, catharsis, fluid replacement, blood perfusion, and in the early stage of treatment of epileptic seizures, the initial routine antiepileptic drugs had poor effect. Then propofol and midazolam were injected into the treatment. The epilepsy was relieved, but the condition deteriorated rapidly, and the patients died eventually. The literature search retrieved 3 patients in the 3 literatures included in the study were analyzed, and their clinical course was similar to that of 4 cases in the center. Necropsy was performedon all 3 patients, and the results were cerebral edema, diffuse cerebral edema, and hemorrhage around the basal ganglia. Conclusion: Acute diquat poisoning can cause epileptic seizures. Once it occurs, the disease progresses rapidly and the prognosis is poor. The combination of large dose of sedative drugs can be used to treat epilepsy in order to improve the prognosis.

Gastric Lavage for Prevention of Feeding Intolerance in Neonates Delivered Through Meconium-Stained Amniotic Fluid: A Systematic Review and Meta-Analysis.

BACKGROUND: The role of gastric lavage in neonates delivered through meconium-stained amniotic fluid remains unclear. OBJECTIVE: This study evaluated the effects of gastric lavage, compared to no gastric lavage, on the incidences of feeding intolerance, respiratory distress, meconium aspiration synd-rome, time to establish breastfeeding, hospitalization and pro-cedure-related complications in late-preterm and term neonates delivered through meconium-stained amniotic fluid. DESIGN: Systematic review and meta-analysis. DATA SOURCES AND SELECTION CRITERIA: MEDLINE, EMBASE, CENTRAL, and other databases were searched for randomized controlled trials and quasi-randomized controlled trials using search terms: neonate OR newborn infant, meconium OR meconium-stained amniotic fluid, and lavage OR gastric lavage from inception to May 2020. Data were pooled in RevMan and analyzed in GRADE. RESULTS: Pooled effects (9 randomized controlled trials, number=3668), showed a significant reduction in the incidence of feeding intolerance (relative risk 0.70; 95% confidence interval 0.58,0.85, I2=0) after gastric lavage. No difference was observed for the incidence of meconium aspiration syndrome (4 studies) or procedure-related complications (7 studies). Only one study, reporting the proportion of neonates with low oxygenation (SpO2<85%), did not find any significant difference. No study evaluated the effects of gastric lavage on respiratory distress, breastfeeding, and hospitalization. CONCLUSIONS: Low-quality evidence supported the role of gastric lavage for the prevention of feeding intolerance in late-preterm and term neonates born through meconium-stained amniotic fluid. Applicability of results was limited by the high risk of bias. Well-conducted randomized controlled trials with important patient outcomes are needed before recommending the practice of gastric lavage.

Successful Treatment of an Acute High-Dose Clozapine Poisoning without Detoxication.

BACKGROUND Clozapine is a well-proven atypical antipsychotic drug used for therapy of treatment-resistant schizophrenia. Over the last decades only a few cases of clozapine poisoning have been reported. Hence, guidelines for in-hospital management are currently not available. Most of the reported cases underwent detoxication measures as charcoal therapy and/or gastric lavage. However, there is no evidence for primary detoxication to improve clinical outcome. In contrast, use of therapy with intravenous physostigmine in the case of anticholinergic syndrome is restricted due to concerns about safety and dosing. We present a case of acute high-dose clozapine poisoning without detoxication and complete recovery supported by physostigmine. CASE REPORT We report the case of a 28-year-old man with prior diagnosed schizophrenia who presumably ingested 8 g (regular maximum daily dose 900 mg/d) of clozapine with uncertain intent. Initial computed tomography (CT) showed pulmonary infiltrates and widespread pneumomediastinum and soft-tissue emphysema of unknown genesis. The patient developed a progressive impairment of vigilance and respiratory insufficiency requiring invasive artificial ventilation for 31 h. Afterwards, an anticholinergic syndrome led again to impaired vigilance, tachycardia, and hyperventilation. To avoid risks associated with artificial ventilation, we applied physostigmine. Subsequently, the anticholinergic syndrome and the pneumomediastinum completely regressed and no further artificial ventilation was needed. CONCLUSIONS Based on the presumably ingested dosage, we present the likely highest reported nonfatal overdose of clozapine without detoxication. Additionally, we observed widespread pneumomediastinum as an uncommon complication. Our approach was to refrain from detoxication to minimize complications and to treat early with physostigmine because of anticholinergic syndrome to minimize its impact and to avoid artificial ventilation due do vigilance impairment.

Combination of antibiotics, gastric lavage and nasojejunal feeding-an effective alternative for the management of acute phlegmonous gastritis: a case report.

BACKGROUND: Phlegmonous gastritis is a rare bacterial infection of the gastric wall, characterised by purulent inflammation of the gastric mucosa, submucosa and muscularis layers. Phlegmonous gastritis has a high mortality rate, even with correct diagnosis and antimicrobial therapy. CASE PRESENTATION: A 22-year-old man presented for acute epigastric pain associated with aqueous diarrhoea, vomiting and sustained fever. Abdominal computed tomography showed diffuse oedema and thickened gastric wall, increased number and size of abdominal lymph nodes and the absence of pneumoperitoneum. Fibregastroscopy revealed oedematous, ridged and thickened gastric mucosa with abundant purulent secretion, especially in the antrum, consistent with phlegmonous gastritis, which was confirmed by histological evaluation of gastric biopsies. Cultures of the tissue biopsies and purulent secretion were positive for Enterococcus cecorum. He was treated with sensitive antibiotics according to the antibiogram, and importantly, with continuous gastric lavage and individualised nutritional support therapy. He eventually recovered well and was discharged with no abdominal symptoms. CONCLUSIONS: Our case indicates that early diagnosis and immediate treatment are crucial to achieve positive outcomes. The combination of sensitive antibiotics, gastric lavage and early enteral nutrition via nasojejunal feeding might be an effective alternative for the comprehensive treatment of acute phlegmonous gastritis.
