Pediatric Carbon Monoxide Poisoning in Southern Israel: A Cross-Sectional Study.

OBJECTIVES: This study aimed to describe the epidemiology and clinical burden of unintended carbon monoxide (CO) poisoning among children in the Negev region of southern Israel. METHODS: This was a cross-sectional retrospective study of CO poisoning patients admitted to Soroka University Medical Center in 2011 through 2015. RESULTS: Overall, 43 cases of CO poisoning were recorded among children younger than 18 years. Five patients died, all upon admission. Poisoning due to smoke "per se" and due to CO emitted from heating devices were responsible for 28 (65.1%) and 14 (32.6%) cases, respectively. Eight (18.6%) patients suffered from convulsions, and 13 (43.3%) of 30 evaluable patients complained of headaches. Twenty-two (51.2%) were found unconscious in the field, and 7 (16.3%) were unconscious at examination at the emergency department. The average carboxyhemoglobin level on admission was 10.5% ± 10.4% (level ranging from 0.1% to 46.2%). Treatment included oxygen in 34 patients (79%) and hyperbaric oxygen therapy in 8 patients (19%). No differences were found between Bedouin and Jewish children in sex, age, residence area, source of CO poisoning, symptoms severity, and need for hyperbaric oxygen therapy. More patients with exposure to water heating devices were older than 4 years, lived in villages, and were diagnosed as having loss of consciousness in the field compared with those exposed to smoke inhalation. CONCLUSIONS: Carbon monoxide poisoning in children is frequent in southern Israel. Education about prevention, implementation of safer standards for home heating systems, and government supervision are required management strategies to decrease the CO poisoning incidence in southern Israel.

[Severe and uncommon complications of anticholinesterase intoxication in children].

BACKGROUND: The Northern region of the Negev desert is an endemic area of organophosphate and carbamate intoxications in Bedouin children. Most victims are intoxicated by drinking the poisonous material kept by the parents in soft drink bottles. Signs and symptoms of intoxication are commonly known and generally include various effects on the central nervous system, usually a decreased level of consciousness in children, cholinergic muscarinic (sweating, rhinorrhea, miosis, vomiting) and nicotinic (weakness) effects. Specific therapy includes Atropine Sulphate and Oximes. PURPOSE AND RESULTS: To describe the course of disease of four (out of 47) children admitted to the Division of Pediatrics with organophosphate or carbamate poisoning during a two-year period. The four children 3-17 years of age ingested the poisonous material: organophosphate chlorpyrifos (2 children); carbamate methomyl (one child) and an unidentified compound in another child. Three of the four patients ingested the poison in a suicide attempt. All 4 children suffered from severe and uncommon complications, including severe respiratory failure from different etiologies. In addition, two of the four suffered from a neurological deficit causing prolonged disability. Three had renal failure necessitating hemofiltration in one case. One child had severe hemodynamic failure and arrhythmias necessitating, among other therapy, the insertion of a temporary pace maker. Two children had (laboratory) pancreatitis. One of the children with severe respiratory failure died after 38 days of extracorporeal membrane oxygenation. CONCLUSIONS: Intoxications by anticholinesterase compounds are not uncommon among Bedouin children in the Negev. This public health threat should be prevented and completely eradicated by the health authorities. Severe intoxication, especially in cases arising after suicide attempts, wherein the amount of the poisonous material is large, may be complicated by life threatening, multi-organ failure during and after the initial phase of poisoning and may progress into prolonged disability and death.

Organophosphate acetylcholine esterase inhibitor poisoning from a home-made shampoo.

Organophosphate acetylcholine esterase inhibitor poisoning is a major health problem in children. We report an unusual cause of organophosphate acetylcholine esterase inhibitor poisoning. Two children were admitted to the pediatric intensive care unit due to organophosphate acetylcholine esterase inhibitor poisoning after exposure from a home-made shampoo that was used for the treatment of head lice. Owing to no obvious source of poisoning, the diagnosis of organophosphate acetylcholine esterase inhibitor poisoning in one of these patients was delayed. Both patients had an uneventful recovery. Organophosphate acetylcholine esterase inhibitor poisoning from home-made shampoo is possible. In cases where the mode of poisoning is unclear, direct questioning about the use of home-made shampoo is warranted, in these cases the skin and particularly the scalp should be rinsed thoroughly as soon as possible.

Epidemiologic, clinical, laboratory, and therapeutic characteristics of influenza A/H1N1 in Moslem Bedouin and Jewish children hospitalized in southern Israel during 2009.

A total of 739 (225 H1N1(+)) children with a diagnosis of acute respiratory infection were hospitalized during July to December 2009. The H1N1(+) children were compared with 225 randomly enrolled H1N1(-) children with an influenza-like illness. As compared with influenza-like illness patients, patients with 2009 influenza A/H1N1 were characterized by older age, more vomiting, less hypoxemia and wheezing, lower white blood cell counts, less neutrophilia, and severe lymphopenia.

Multiple hymenoptera stings in children: clinical and laboratory manifestations.

Multiple hymenoptera stings are a cause of rhabdomyolysis, elevated liver enzymes, clotting abnormalities, kidney injury, and even death. However, the progression of the clinical and laboratory findings has been described mainly in sporadic case reports. We report the clinical and laboratory manifestations of multiple hymenoptera stings in six children who were hospitalized and referred for a nephrology evaluation and follow-up over a 12-year period. One patient succumbed 13 h after the stinging accident. In the five surviving patients, we found somewhat similar pattern of clinical and laboratory course: rhabdomyolysis with elevated liver enzymes are the earliest manifestations, followed by kidney injury and anemia. An asymptomatic phase of several days between the stinging accident and severe kidney injury can occur. There was a strong seasonal association, with all six events occurring in August or September. In children with multiple hymenoptera stings, a somewhat predictable clinical and laboratory course is expected and an initial laboratory evaluation is needed, and even in asymptomatic children, a repeated laboratory evaluation is highly recommended.

Organophosphate and carbamate poisoning: review of the current literature and summary of clinical and laboratory experience in southern Israel.

Organophosphate and carbamate are mainly used to kill insects, thereby protecting livestock, crops, homes and communities. Yet, these compounds also convey great danger. OP and CRB poisoning is an important clinical problem, often life-threatening, especially in the pediatric population in rural areas where reaching a physician or hospital on time is difficult. We present a summary of accumulated toxicological knowledge as well as clinical and laboratory experience from a medical center serving a relatively vast rural area and pediatric population. We stress the importance of knowing how to recognize the classic signs of OP and CRB poisoning and when it is appropriate to investigate for such poisoning even in the absence of those signs. Like any medical emergency, OP and CRB poisoning requires prompt resuscitation and use of antidotes. Atropine, oxygen and fluids are the mainstay of therapy. Oximes, which were found useful in some cases of OP poisoning and useless in some cases of CRB poisoning, are absolutely safe as empiric treatment, which is often needed since the major differential diagnosis of OP poisoning is CRB poisoning, which is clinically indistinguishable. We hope that continuing research will offer further insights into the management of such events, and we are confident that improved medical management of OP and CRB poisoning will result in a reduction of morbidity and other complications associated with intensive care procedures and hospitalization.

Interleukin-12 receptor beta1 deficiency presenting as recurrent Salmonella infection.

We describe a child with interleukin-12 receptor beta1 (IL-12Rbeta1) deficiency caused by a homozygous IL12RB1 large deletion who presented at the age of 1 year with recurrent, often asymptomatic episodes of bacteremia caused by group D Salmonella species. No mycobacterial disease or other unusual infection was present. The episodes of salmonellosis were caused by an identical serovar during a period of 18 months. This is the first case of inherited IL-12Rbeta1 deficiency diagnosed after isolated, recurrent salmonellosis.

Walterinnesia aegyptia envenomation in a 22-year-old female: a case report.

A 22-year-old woman was bitten on the third finger of her left hand by a Walterinnesia aegyptia (desert black cobra). Local signs included a marked swelling of the entire hand with pain along the left upper limb. Systemic reactions were irritability, fever, tachycardia, ventricular premature beats, nausea and high blood leukocytes count. About 15 h post-envenomation the patient had no symptoms except for a mild swelling of the hand. Despite the severe toxic venom composition of the W. aegyptia, the clinical course of our patient was relatively benign. This could be explained by the snake's behavior and the mechanism by which the venom penetrates the body. A survey of the literature revealed only a few clinical cases reported. Most of the information concerning W. aegyptia was collected from laboratory and animal studies.

Cerastes cerastes envenomation in an 18 year old female: a case report.

An 18 year old woman was bitten on the second finger of her right hand by a Cerastes cerastes. A literature search revealed very few clinical cases, and most of those were only laboratory and in 'vitro studies'. Local signs included a hemorrhagic wound at the site of the bite with marked swelling of the entire hand. Twelve hours later, the patient developed coagulopathy, which lasted 3 days and required repeated administration of blood products. Treatment was essentially supportive and the patient was discharged from the hospital after 5 days in good condition.
