✨ta-da✨

Emery. Succimer child. We love her

[havemyheartt]

a few of my f/os (Blue, Green, Korah, n Ian) are pumped full of headcanons cuz they don’t exactly have canon personalities all that much. The one that has the most personality per se is Green but that’s because of the OVA (thanks Kokoro :3)

so. these guys just have a bunch of headcanons. yaya

selfshippers always characterize their f/os 1000x better than canon x canon shippers and I appreciate that dearly 🫶 🫶 🫶

I had a 2 year old in clinic today whose lead level was elevated. It was 56 after the nurse checked it twice. This is what UpToDate says about management of elevated lead levels: The only effective long-term treatment is ending further lead exposure by eradication of environmental lead contamination. Because of the cognitive and behavioral effects of lead toxicity, primary prevention of lead exposure is the single most important strategy in the management of childhood lead poisoning.

Children at risk because of lead in their environment are often not found until elevated blood lead levels (BLLs) are detected during routine screening. At that point, secondary prevention of further lead exposure becomes the main treatment:

1) Report to appropriate health authorities (eg, city, county, or state health department)

2) Take emergency measures to reduce lead exposure. Relocate the child and family to lead-free housing if necessary.

3) Initiate intensive blood lead screening and/or chelation as determined by the degree of the child's blood lead elevation.

4) Educate the family about sources of lead exposure so that they can be eliminated

5) Follow-up on long-term abatement procedures by a licensed contractor to reduce lead exposure.

Chelation therapy may be necessary depending upon the degree of blood lead elevation (see 'Lead level 45 to 69 mcg/dL' below and 'Symptomatic lead poisoning' below). However, it has limited efficacy. With chronic ingestion or inhalation, lead can be incorporated into the skeletal system, which becomes an endogenous reservoir of lead that is resistant to elimination. While chelating agents can bind to lead in blood, they are ineffective in removing lead from the deep bone stores.

Lead level 45 to 69 mcg/dL — Asymptomatic children with venous BLLs 45 to 69 mcg/dL (2.17 to 3.33 micromol/L) should have a confirmatory venous lead level within 48 hours. These patients should also receive the same general management as for children with lower levels as described above and listed in the table.

We recommend that asymptomatic children with BLL ≥45 mcg/dL (2.17 micromol/L) receive chelation therapy. Treatment should begin as soon as possible after the BLL is confirmed, and only when the child is in a lead-safe environment. We suggest that chelation be performed orally with succimer (table 6) rather than by continuous infusion of calcium disodium edetate (CaNa2EDTA) or oral penicillamine. If succimer is contraindicated, not tolerated, or causes significant adverse reactions, then CaNa2EDTA is suggested [37]. Chelation should be performed in consultation with a toxicologist or clinician who has experience with the chelating agents.

Ongoing care includes:

●BLLs should be measured weekly at the end of oral chelation until the lead level plateaus to ensure no sudden increase from re-exposure. The interval for testing may be increased once the level plateaus and no ongoing exposure occurs.

●Retreatment with chelation therapy should occur if the BLL rebounds to >80 percent of the original lead level and is ≥45 mcg/dL (2.17 micromol/L).

●An acute rise in levels may signify a new exposure to lead, and repeat evaluation, including a plain abdominal radiograph, and renewed surveillance of the child's environment will be necessary. This is especially true if the "rebound" levels rise above pre-chelation levels.

Symptoms attributable to lead poisoning can include intermittent vomiting, anorexia, and abdominal pain (lead colic); intermittent irritability or lethargy; and/or lead encephalopathy (eg, persistent vomiting, persistent lethargy or coma, headache, or afebrile convulsions)

Symptomatic lead intoxication is a medical emergency warranting an emergency repeat blood lead level (BLL) for confirmation, emergency evaluation, hospitalization, and chelation. Children with lead encephalopathy should be admitted to a pediatric intensive care unit.

Performing a lumbar puncture should be avoided in encephalopathic children unless absolutely necessary to rule out meningitis because lead intoxication can cause increased intracranial pressure. Extreme caution should be exercised if lumbar puncture is attempted, and only a small amount of spinal fluid (less than 1 mL) should be removed.

Succimer — Succimer (meso-2,3-dimercaptosuccinic acid) is a water-soluble analog of dimercaprol (British anti-Lewisite, BAL) that can be administered orally [48,49]. Like dimercaprol and CaNa2EDTA, succimer increases the urinary excretion of lead.

Calcium disodium edetate — In 1950, calcium disodium edetate (CaNa2EDTA), was found to be clinically useful in the treatment of lead poisoning. Like dimercaprol, CaNa2EDTA increases the urinary excretion of lead through the formation of a nonionizing, soluble chelate.

Dimercaprol — Dimercaprol (2,3-dimercapto-1-propanol), also known as British Anti-Lewisite or BAL, was developed in 1946 by the British to counteract German arsenical war gases. It was the first chelating agent found to be useful in the treatment of childhood lead poisoning. Dimercaprol increases the fecal and urinary excretion of heavy metals through the formation of stable, nontoxic, soluble chelates. Dimercaprol lacks stability in water and must be dissolved in peanut oil for deep intramuscular injection.

D-penicillamine — D-penicillamine is another oral chelating agent. It was developed originally to reduce serum copper concentration in patients with Wilson disease [67]. American Academy of Pediatrics (AAP) guidelines for the treatment of lead toxicity describe penicillamine as a third-line agent, indicated only when unacceptable reactions have occurred to succimer or CaNa2EDTA, and continued therapy is required. Given the potential for significant adverse events (including leukopenia, thrombocytopenia, hematuria, abnormal liver function, urticaria, angioedema, Stevens-Johnson syndrome, and nephritic syndrome), use of this agent is not generally recommended and consultation with a clinician with expertise in managing pediatric lead poisoning with D-penicillamine chelation is advised before starting this treatment

From First Aid for USMLE Step 2 CK

Dimercaprol is a chelating agent (binds to heavy metals).

In a fire, burning textiles generate cyanide. You also are exposed to carbon monoxide in a fire. So for anyone who was in a fire in an enclosed space, check for carbon monoxide and cyanide poisoning.

If someone has cyanide poisoning due to the anti-hypertensive drug nitroprusside, you can treat it with amyl nitrite. But amyl nitrite should not be used to treat cyanide poisoning due to smoke inhalation because amyl nitrite-> methemoglobin, which worsens the carboxyhemoglobinemia that occurs with carbon monoxide poisoning. So if the pt has cyanide poisoning due to smoke inhalation, treat it with thiosulfate.

Harmful Treatment #1: Chelation

Chelation is a chemical process in which a substance is used to bind molecules, such as metals or minerals, and hold them tightly. It is originally used to rid the body of excess or toxic metals. It has some uses in conventional medicine, such as treating lead poisoning or iron overload.

During the process of chelation, a synthetic solution-EDTA (ethylenediaminetetraacetic acid) is injected into the bloodstream to remove heavy metals and/or minerals from the body.

This treatment stems from the idea that vaccines cause Autism, which is an untrue claim with no scientific evidence to back it up. 

Chelation Therapy is used as a treatment for acute heavy metal poisoning in removing metals such as arsenic, lead, and mercury from the bloodstream with the administrating of chelating agents. The medication binds to the heavy metals and then would be filtered out through urine. Chelating agents are nondiscriminating and they will bind to any heavy metal it comes to contact in, which can result in vital metals, such as calcium and iron, to be filtered out of the body alongside with the toxins if administrated incorrectly. There are several different types of Chelating drugs that are used depending on the type of poisoning that has occurred. Each one has its own benefits and risks to it.

The different types include:

Succimer (DMSA, 2,3-dimercaptosuccinic acid) is taken by mouth to treat poisoning by lead, mercury, and arsenic. Serious side effects are uncommon.

Dimercaprol (British Anti-Lewisite, BAL) is given by injection to treat severe lead, mercury, and arsenic poisoning. Side effects are usually dose-related but can cause coma and seizures.

Edetate calcium disodium (CaNa2EDTA) is given intravenously to treat severe lead poisoning. This can be toxic to the kidneys.

Deferoxamine is given intravenously to treat iron poisoning. Possible side effects include very low blood pressure, lung injury, and infections

Penicillamine is sometimes used to treat bismuth, copper, lead, mercury, and nickel toxicity. The primary adverse effect is an allergic reaction in people who are also allergic to penicillin.

There have been several unapproved uses for Chelation Therapy as of late for treatment in the autism spectrum, cardiovascular diseases, Parkinson's disease, Alzheimer's disease, and other serious conditions.

The idea of using Chelation for these purposes is that it is believed that the caused for these disorders are caused by damage from heavy metal poising. For autism, it is believed that the cause may be mercury poisoning from the thimerosal in vaccines.

Prescrire réserve son jugement sur Spinraza* et Bavencio*

La revue Prescrire, dans son numéro d'août, a refusé de se prononcer sur le bénéfice du traitement de l'amyotrophie spinale Spinraza* (nusinersen, Biogen) et de l'anti-PD-L1 Bavencio* (avélumab, Merck KGaA/Pfizer).

L'oligonucléotide antisens Spinraza* est le premier médicament à avoir décroché une autorisation de mise sur le marché (AMM) européenne dans le traitement de l’amyotrophie spinale 5q, en mai 2017, rappelle-t-on. 

Si "la rédaction ne peut se prononcer", c'est que les inconnues concernant les effets indésirables sont "encore nombreuses", malgré une réduction de la mortalité à court terme sans effet important sur le handicap. Prescrire considère qu'il est préférable de réserver Spinraza* à la recherche clinique.   

"Autoriser ce médicament sur la base d'une telle évaluation place les parents et les soignants à la hauteur des incertitudes, car à partir des données disponibles, on ne peut pas déduire ce que vont avoir à vivre les nourrissons traités", souligne Prescrire.  

La revue consacre par ailleurs son éditorial au "prix exorbitant" de Spinraza*, dont le coût de traitement atteint 500.000 euros la première année et 250.000 les suivantes. "Partout dans le monde, le prix monstrueux de certains nouveaux médicaments épuise leur valeur pratique", souligne cet éditorial.

Bavencio* a été homologué en septembre 2017 dans le traitement en monothérapie du carcinome métastatique à cellules de Merkel chez l'adulte. A ce jour, la balance bénéfices/risques est "incertaine", juge Prescrire.

L'essai clinique ne démontre pas que Bavencio* apporte un "avantage clinique concret" par rapport à des soins symptomatiques. Les données ne sont pas comparatives pour attester l'effet antitumoral du produit et le recul est à ce jour insuffisant pour savoir si cela modifie le pronostic ou la qualité de vie des patients, alors que les effets indésirables sont nombreux et parfois graves.

Prescrire juge aussi que l'anticancéreux Tecentriq* (atézolizumab, Roche) "n'apporte rien de nouveau" dans une des deux indications de son AMM initiale concernant le carcinome urothélial localement avancé ou métastatique, chez les patients déjà traités avec une chimiothérapie à base de sels de platine ou considérés comme inéligibles au cisplatine, peu importe le statut de PD-L1. L'autre indication concerne le cancer du poumon non à petites cellules (NAPC), rappelle-t-on.

Dans l'essai clinique, Tecentriq* "n'a pas été plus efficace" sur la mortalité que des taxanes ou la vinflunine (Javlor*, Pierre Fabre), mais il présente toutefois un profil d'effets indésirables potentiellement plus faibles.

Prescrire juge que Stelara* (ustékinumab, Janssen, groupe Johnson & Johnson) n'apporte rien dans le traitement de la maladie de Crohn active modérée à sévère chez les patients adultes présentant une réponse insuffisante, une perte de réponse ou une intolérance à un traitement conventionnel ou par anti-TNF alpha ou qui présentent une contre-indication médicale à ces traitements.

Stelara* n'a pas été comparé à un anti-TNF alpha et, en cas d'échec avec un produit de ce type, il entraîne une rémission clinique seulement chez une minorité de patients sans prouver un maintien de cet effet à long terme. Les effets indésirables sont nombreux et parfois graves.

Améliorations dans la "vraie vie"

L'insuline aspart à action ultra-rapide Fiasp* (Novo Nordisk) n'apporte rien de nouveau car le délai d'action est réduit de cinq minutes par rapport à NovoRapid*, sans preuve que cette différence apporte un progrès en cas d'injection après un repas.

Prescrire a évalué deux fois Trolovol* (D-pénicillamine, Erempharma) dans son numéro d'août:

il est "éventuellement utile" dans le traitement de la cystinurie (extension d'AMM obtenue fin 2016) car il constitue une alternative à Acadione* (tiopronine, Sanofi) qui a cessé d'être commercialisé, malgré une évaluation jugée pas assez rigoureuse

mais la revue n'est "pas d'accord" pour son extension d'AMM de 2016 dans le traitement de l’intoxication au plomb car son efficacité semble inférieure à Succicaptal* (succimer, SERB) et son profil d'effets indésirables est "plus préoccupant", sans qu'une formulation soit adaptée aux enfants.

Les antihypertenseurs à base d'olmésartan Alteis* et Olmetec* (Daiichi Sankyo) ont écopé de la mention "pas d'accord" dans leur indication pédiatrique car la balance bénéfices/risques est négative et les effets indésirables nombreux.

La nouvelle formulation buvable de l'enzyme de conversion captopril Noyada* (Martindale Pharma) apporte quelque chose car elle permet une "adaptation précise" des doses et facilite l'administration.

La chronique "Le mot de Gaspard" est consacrée à cette nouvelle présentation: si les autorités sanitaires ne voient pas toujours les améliorations qui rendent plus pratiques dans la "vraie vie" certains médicaments, cela n'en constitue pas moins un progrès.

La nouvelle présentation du traitement de la fibrose pulmonaire idiopathique Esbriet* (pirfénidone, Roche) en comprimés à 267 mg et 801 mg n'apporte rien de nouveau car ils sont équivalents aux gélules, soit gros à avaler et avec une balance bénéfices/risques de la pirfénidone incertaine.

Prescrire a aussi considéré que le premier traitement à base de plantes avec le statut de médicament indiqué dans les troubles du climatère liés à la périménopause Fémélis* (Sérélys Pharma) n'apporte rien de nouveau "faute de données cliniques spécifiques" empêchant de savoir si les femmes sont soulagées d'une gêne liée à la ménopause ou d'un syndrome prémenstruel. Des réactions allergiques peuvent survenir.

Le numéro d'août de Prescrire consacre par ailleurs des articles ou dossiers aux lithiases vésiculaires d'origine médicamenteuse, à la désensibilisation de la rhinite allergique saisonnière, aux morsures de chien ou de chat, aux critères combinés dans les essais cliniques, à l'évaluation des technologies de santé et aux IVG médicamenteuses.

A haiku on lead poisoning

Red cells get stippled Chelate lead with succimer Consider the source

[mcatmemoranda]

Lead interferes with numerous bodily processes and affects various organ systems including cardiovascular, nervous, hematopoietic and renal systems. Young children are most commonly exposed to lead through lead based wall paint in their homes, while adults are most commonly exposed due to occupational exposures. Manifestations of acute poisoning can vary and either be asymptomatic or can include symptoms such as altered mental status, seizures, motor weakness, abdominal pain, vomiting, constipation, headaches, ataxia, somnolence and weakness secondary to hemolytic anemia. History of exposure whether environmental or occupational is vital to making the diagnosis. The combination of any neurological abnormalities, abdominal pain and hemolytic anemia should increase the suspicion for this diagnosis. The definitive diagnosis is made with a serum blood lead level. Levels that are greater than 10 µg/dL is considered elevated. The three therapies available for the treatment of lead toxicity include chelation therapy with dimercaprol, edetate calcium disodium, or succimer. The choice of chelation therapy is based on the patient's age, serum lead levels, and symptom manifestation.

Bottom Line: When suspecting the diagnosis of lead poisoning, the serum lead level is the most important diagnostic modality.
