First Tunisian Cluster Admissions of Critically Ill Patients with Multisystem Inflammatory Syndrome in Children (MIS-C).

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a new emerging severe disease that is temporally related to previous exposure to coronavirus infection disease (COVID-19). AIM: To describe the clinical features, laboratory findings, therapies, and outcomes for the first Tunisian cluster admissions of critically ill children with severe MIS-C. METHODS: Retrospective study conducted from November 01 to November 30, 2020According to the WHO definition case, we included eight children aged less than 15 years who were admitted to our pediatric intensive care and met MIS-C criteria. We reviewed all patients' medical records to collect demographic and clinical data, severity scores, laboratory test results, echocardiographic findings, treatment, and outcomes. RESULTS: The median age was 8 years (IQR: 4-10years). All children were previously fit and well. Seven patients were boys. Known exposure to COVID-19 was reported in 4 cases. Fever and gastrointestinal symptoms were reported in all cases. Five patients had marked abdominal pain and were examined by the surgeon for possible appendicitis. Seven patients had diarrhea. On examination, we found rash (n=7), conjunctivitis (n=7), cheilitis (n=5), and meningism (n=3). We reported cardiac dysfunction in 7 cases and shock with hypotension in 3 cases. All patients received immunoglobulins, methylprednisolone, and a low dose of aspirin. No deaths occurred. CONCLUSION: We reported here the first Tunisian cluster admissions of 8 critically ill children with MIS-C to highlight the increase of a new severe emerging disease with evidence of prior COVID-19 infection in older children.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module.

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.

Findings of the International Nosocomial Infection Control Consortium (INICC), part III: effectiveness of a multidimensional infection control approach to reduce central line-associated bloodstream infections in the neonatal intensive care units of 4 developing countries.

OBJECTIVE: To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach to reduce central line-associated bloodstream infection (CLABSI) rates. SETTING: Four neonatal intensive care units (NICUs) of INICC member hospitals from El Salvador, Mexico, Philippines, and Tunisia. PATIENTS: A total of 2,241 patients hospitalized in 4 NICUs for 40,045 bed-days. METHODS: We conducted a before-after prospective surveillance study. During Phase 1 we performed active surveillance, and during phase 2 the INICC multidimensional infection control approach was implemented, including the following practices: (1) central line care bundle, (2) education, (3) outcome surveillance, (4) process surveillance, (5) feedback of CLABSI rates, and (6) performance feedback of infection control practices. We compared CLABSI rates obtained during the 2 phases. We calculated crude stratified rates, and, using random-effects Poisson regression to allow for clustering by ICU, we calculated the incidence rate ratio (IRR) for each follow-up time period compared with the 3-month baseline. RESULTS: During phase 1 we recorded 2,105 CL-days, and during phase 2 we recorded 17,117 CL-days. After implementation of the multidimensional approach, the CLABSI rate decreased by 55%, from 21.4 per 1,000 CL-days during phase 1 to 9.7 per 1,000 CL-days during phase 2 (rate ratio, 0.45 [95% confidence interval, 0.33-0.63]). The IRR was 0.53 during the 4-12-month period and 0.07 during the final period of the study (more than 45 months). CONCLUSIONS: Implementation of a multidimensional infection control approach was associated with a significant reduction in CLABSI rates in NICUs.

Neurological variant of Lemierre's Syndrome with purulent meningitis: a case report and literature review.

We report an unusual variant of Lemierre's Syndrome (LS) in a 10-year-old-girl admitted to the intensive care unit for septic shock with meningitis. The primary infection was otitis media. A gram negative bacillus was identified in the direct exam of the purulent ear discharge and the cerebrospinal fluid but cultures were negative. Computerized tomography of the neck revealed a thrombus in the internal jugular vein. Septic shock improved rapidly under supportive treatment. The patient recovered without sequellae after a prolonged duration of parenteral antibiotherapy and hospital stay. Neurologic variants of LS with meningitis, previously reported in the literature, are reviewed.

Findings of the International Nosocomial Infection Control Consortium (INICC), Part II: Impact of a multidimensional strategy to reduce ventilator-associated pneumonia in neonatal intensive care units in 10 developing countries.

Design. Before-after prospective surveillance study to assess the efficacy of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control program to reduce the rate of occurrence of ventilator-associated pneumonia (VAP). Setting. Neonatal intensive care units (NICUs) of INICC member hospitals from 15 cities in the following 10 developing countries: Argentina, Colombia, El Salvador, India, Mexico, Morocco, Peru, Philippines, Tunisia, and Turkey. Patients. NICU inpatients. Methods. VAP rates were determined during a first period of active surveillance without the implementation of the multidimensional approach (phase 1) to be then compared with VAP rates after implementation of the INICC multidimensional infection control program (phase 2), which included the following practices: a bundle of infection control interventions, education, outcome surveillance, process surveillance, feedback on VAP rates, and performance feedback on infection control practices. This study was conducted by infection control professionals who applied National Health Safety Network (NHSN) definitions for healthcare-associated infections and INICC surveillance methodology. Results. During phase 1, we recorded 3,153 mechanical ventilation (MV)-days, and during phase 2, after the implementation of the bundle of interventions, we recorded 15,981 MV-days. The VAP rate was 17.8 cases per 1,000 MV-days during phase 1 and 12.0 cases per 1,000 MV-days during phase 2 (relative risk, 0.67 [95% confidence interval, 0.50-0.91]; [Formula: see text]), indicating a 33% reduction in VAP rate. Conclusions. Our results demonstrate that an implementation of the INICC multidimensional infection control program was associated with a significant reduction in VAP rate in NICUs in developing countries.

Lidocaine toxicity secondary to local anesthesia administered in the community for elective circumcision.

We report three previously healthy infants aged, respectively, 23 days, 6 weeks, and 3 months with systemic lidocaine toxicity following administration of subcutaneous lidocaine for regional anesthesia during an elective circumcision. The patients developed a generalized seizure requiring endotracheal intubation but recovered fully with supportive care. We report the clinical details of these cases as well as a review of lidocaine toxicity.

[Outcome at 2 years of very premature infants. A Tunisian series]. / Devenir neurologique à l'âge de 2 ans des grands prématurés. Série Tunisienne.

BACKGROUND: Neurodevelopmental outcome of very premature infant can be associated with a high rate of cerebral palsy. AIM: To assess the impact of very preterm birth on neurological outcome at the age of two years. METHODS: Retrospective study of all cases of very premature infants born at less than 33 weeks of gestational age, during the years 2005 to 2007. Neurodevelopmental outcome is reported. RESULTS: During the study period, the very premature infant rate was 1.5 %. A complete information about neurological outcome at the age of two years, was obtained in 60 cases.Eight infants (13.4%) showed major handicap (cerebral palsy) and four others infants developed neurosensoriel difficulties. CONCLUSION: The incidence of neurosensoriel handicap in our population seems relatively high. A strong effort must be made for identification of risk factors of neurodevelopmental disability.

Management of meconium aspiration syndrome with highfrequency oscillatory ventilation.

BACKGROUND: High-frequency oscillatory ventilation (HFOV) has been advocated for use to improve lung inflation while potentially decreasing lung injury. There were few data on the early use of HFOV in hypoxemic term neonates. AIM: To evaluate the effectiveness of HFOV, used as the initial mode of ventilation, in neonates with severe meconium aspiration syndrome (MAS). METHODS: In a tertiary care paediatric intensive care unit, 17 term neonates with severe MAS were managed with HFOV, used as the initial mode of ventilation, and prospectively evaluated. Ventilator settings, blood gases, oxygenation index (OI) and alveolar-arterial oxygen difference (P(A-a)O2) were prospectively recorded during HFOV treatment and compared at the multiple time intervals. RESULTS: Target ventilation was easily achieved with HFOV. Initiation of HFOV caused a significant decrease in FIO2, achieved as early as 1 hour (from 0.93 ± 0.11 to 0.78 ± 0.25; p=0.031) and the improvement was sustained during the 1-32 hours period. There were a significant decreases in P (A-a) O2 and OI, respectively, at 4 hours (from 562.5 ± 71.7 to 355.4 ± 206 mm Hg; p=0.03) and 8 hours (from 23.3±17 to 14.6±16.3; p=0.04), that were sustained up to 16 and 40 hours . Three neonates (17.6%) developed pneumothorax on HFOV. One patient required oxygen support at 28 days. No significant others complications associated with HFOV were detected. Sixteen infants (94 %) were successfully weaned from HFOV and 15 (88%) survived to hospital discharge. CONCLUSION: Use of HFOV as the initial mode of ventilation in neonates with severe MAS is an effective strategy.

Datura stramonium L. poisoning in a geophagous child: a case report.

Datura stramonium L. (DS) is a wild-growing plant widely distributed and easily accessible. It contains a variety of toxic anticholinergic alkaloids such as atropine, hyoscamine, and scopolamine. Voluntary or accidental ingestion can produce severe anticholinergic poisoning. We report an unusual case of DS intoxication occurring in a geophagous young child after accidental ingestion of the plant. Our case is original because of the young age of the victim and the underlying geophagia facilitating the occurrence of poisoning.

Fatal subdural empyema caused by Streptococcus constellatus and Actinomyces viscosus in a child--case report.

Group milleri streptococci that colonize the mouth and the upper airways are generally considered to be commensal. In combination with anaerobics, they are rarely responsible for brain abscesses in patients with certain predisposing factors. Mortality in such cases is high and complications are frequent. We present a case of fatal subdural empyema caused by Streptococcus constellatus and Actinomyces viscosus in a previously healthy 7-year-old girl.

Community acquired methicillin-resistant Staphylococcus aureus preseptal cellulitis complicated by zygomatic osteomylitis, cavernous sinus thrombosis and meningitis in a healthy child.

We report a case of community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA) preseptal cellulitis complicated by zygomatic osteomyelitis, cavernous sinus thrombosis, meningitis, and necroziting pneumonia in a previously healthy two and half month old girl. This case exemplifies an aggressive and disseminated CA-MRSA infection with deep venous thrombosis in an infant without predisposing risk factors. The literature is reviewed and recommendations for management are provided.

[Early neonatal infection caused by Streptococcus pneumonias: report of 3 cases]. / Infection neonatale precoce a streptococcus pneumoniae: a propos de 3 observations.

BACKGROUND: S pneumoniae is a rare cause (1-8 %) of maternofetal infection causing an important morbi-mortality in the newborn and the mother. AIM: To report 3 cases of early neonatal infection due to S pneumonia. CASES REPORT: Three cases of early neonatal infection due to S pneumoniae are reported. The three newborns were at term or near term babies with a vaginal delivery in two cases and a caesarean section in one case. They presented severe symptoms, with a progressive onset after birth, leading to hypoxemic pneumonia in one case and to septic shock in two newborns associated with meningitis in one case. S pneumoniae was isolated in the blood culture in two patients with positive soluble antigens in the cerebrospinal fluid in one case and positive peripheral bacteriological swabs in the other case. In the third case, S pneumoniae was isolated in the tracheal sample of the newborn and his mother. S pneumoniae was sensitive to ampicillin in two patients and of decreased sensitivity to ampicillin in one patient. The clinical course was favourable in the three patients after hospitalization in the intensive care unit. CONCLUSION: Early neonatal infections caused by S pneumonia are rare and are an important cause of morbi-mortality in the newborn and the mother.

Toxic epidermal necrolysis complicated by small bowel intussusception: a case report.

Intestinal involvement in toxic epidermal necrolysis (TEN) has been identified only rarely. We report a case of TEN complicated by small bowel intussusception. The patient was a previously healthy 8-year-old boy who presented with TEN and extensive lesions, including up to 40% of the body surface area as well as conjunctival, oropharyngeal, respiratory, and genital mucosa. Rapidly after the onset of a constant rate of enteral feeding, he developed bilious vomiting, diarrhea, and significant abdominal distension. Abdominal sonography showed a small bowel intussusception. At abdominal exploration, an ileoileal intussusception was observed with a viable but inflamed bowel wall. Manual reduction was performed. During the postoperative clinical course, the patient was managed with total parenteral nutrition and local care of the skin and mucous membranes. Enteral feeding was introduced on the sixth postoperative day, and the child left the hospital 15 days after his admission. The association of TEN and small bowel intussusception has not been previously reported in the literature.

Multifocal atrial tachycardia: an unusual cause of cardiogenic shock in a newborn.

BACKGROUND: Chaotic or multifocal atrial tachycardia (MAT) is a rare tachyarrhythmia in children, accounting for less than 1% of supraventricular tachycardia seen in childhood. The majority of children with MAT are healthy; a few may exhibit mild to life threatening cardiorespiratory disease. AIM: To report a new case of MAT revealed by a severe respiratory distress and cardiogenic shock. CASE REPORT: We report a rare case of MAT revealed by a severe respiratory distress and cardiogenic shock in a 12-day-old newborn. The echocardiogram demonstrated an isolated secundum-type atrial septal defect with a decreased left ventricular function. He was successfully treated with intravenous amiodarone. A relay by oral amiodarone and digoxine was made. Four months later, he had no recurrence of arrhythmia and left ventricular function returned to normal. CONCLUSION: Our case is original by its association to an isolated ostium secondum-type atrial septal defect and by the occurrence of a congestive heart failure revealing the arrhythmia and the structural heart disease during the neonatal period.

Hepatorenal injury induced by cutaneous application of Atractylis gummifera L.

INTRODUCTION: In Mediterranean countries, intoxication by Atractylis gummifera L. is frequent and characterized principally by hepatorenal injury, often fatal. Its toxicity after a cutaneous application is unknown. We report a case of poisoning by A. gummifera L. induced by repeated cutaneous application. CASE REPORT: A 30-month-old boy was admitted in our pediatric intensive care unit in coma (Glasgow Coma Scale 8). Investigations showed hepatic cellular injury, cholestasis, decreased prothrombin level, and increased creatinine. History from the parents revealed repeated and occlusive cutaneous application of A. gummifera L. on a skin burn. Qualitative analysis of urine confirmed the diagnosis of A. gummifera poisoning. The child was discharged after 16 days of hospitalization with residual renal insufficiency. DISCUSSION: Poisoning by A. gummifera L. after cutaneous application has not previously been reported in the literature. The prevention of this poisoning, particularly frequent in Mediterranean countries, is mainly based on the education of the public concerning the dangers of this plant.

Respiratory failure revealing a multilocular thymic cyst in an infant.

Multilocular thymic cysts are rare benign acquired lesions of the neck and mediastinum. In children, multilocular thymic cysts are usually symptomatic after the age of 2 years and produce few symptoms. We report an unusual case of a multilocular thymic cyst diagnosed in a 3-month-old girl, causing severe respiratory failure. We believe that this unusual presentation has not been previously reported in the literature.

Unusual cause of severe toxic methemoglobinemia in an infant: a case report.

Toxic methemoglobinemia is an uncommon blood disorder induced by exposure to certain oxidizing agents and drugs. In severe cases, this condition may rapidly lead to major cardiopulmonary compromise and constitutes an emergency requiring prompt recognition and early management. We report an unusual case of severe toxic methemoglobinemia following wide cutaneous application of a pomade containing benzocaine, resorcin, and oxyquinoline (Nestosyl) in an infant.
