EDITORIAL ESPAÑOL 
====================
Hola amigos de la red, DERMAGIC de nuevo con ustedes. El tema de hoy  EL SÍNDROME LARVA MIGRANS CUTÁNEA, Y LAS MASCOTAS (PERROS Y GATOS)  

Nos encantan las mascotas, sobre todo los perros y gatos. Pero en la mierda (caca) de estos bellos animales hay unos parásitos que pueden pasar a la piel cuando la tocamos o ingerimos, 

 El sitio favorito para contraerla es la PLAYA o el CAMPO donde nuestras  lindas mascotas hacen  su mierda. Luego venimos nosotros e ingenuamente ponemos en contacto alguna parte de nuestro cuerpo (principalmente el pie) con el pupú-caca, y la larva penetra nuestra piel directamente desde las heces provocando la enfermedad. 

También en los hogares donde hay perros y gatos no controlados por el veterinario. En fin una enfermedad más donde el hombre es  accidentalmente contaminado por el animal. 

Hoy en dia descrita en algunas publicaciones como "el souvenir de los viajeros y turistas" que la contraen en sus viajes de vacaciones. Varios parásitos son los agentes causales pero los más comunes son: ANCYLOSTOMA CANInum y ANQUILOSTOMA. BRAZILIENSE. 

OTROS AGENTES CAUSALES:

- Ancylostoma ceylanicum, A. tubaeforme (perros y gatos)

- Gnathostoma spinigerum (gatos, perros, cerdos)
 
- Uncinaria stenocephala (perros en Europa)

- Bunostomum phlebotomum (ganado)

- Pelodera strongyloides

- En raros casos, Ancylostoma duodenale, Necator americanus (uncinarias humanas), y strongyloides stercoralis.
 
 La LARVA MIGRANS CUTÁNEA, es una enfermedad SUPERFICIAL, el parásito vive en la capa superficial de la piel, haciendo túneles a medida que crece, denominada también "erupción progresiva o serpigimosa", pero es auto limitada y con un buen tratamiento desaparece sin dejar complicaciones en la mayoría de los casos.
 
La LARVA MIGRANS CUTÁNEA presenta una variante denominada PANICULITIS NODULAR MIGRATORIA:  se presenta cuando las larvas migran hacia el panículo adiposo (mas profundamente), formando nódulos, subcutáneos migratorios, edema y eosinofilia. Los agentes causales que producen esta variante son:
 
- Gnathostoma spinigerum.

- Gnathostoma doloresis.

- Gnathostoma hispidum.
 
LARVA MIGRANS VISCERAL: 
 
Hay otra variante de la LARVA MIGRANS QUE ES LA VISCERAL (PROFUNDA) causada por otros parásitos como el Toxocara canis (Perro) y otros mas, donde el el parásito "migra: a órganos profundos como: CAVIDAD VISCERAL OJO, CEREBRO, MÚSCULOS Y OTROS. esta es más peligrosa y puede dejar secuelas si no es detectada y tratada a tiempo. 
 
AGENTES CAUSANTES DE LARVA MIGRANS VISCERAL:
 
- Toxocara canis (perros)
 
- Toxocara cati (gatos) 
 
TRATAMIENTOS DE LA LARVA MIGRANS:
 
1.) Ivermectina:

Dosis: 200 mcg/kg (0.2 mg/kg) en dosis única (puede repetirse a los 7-14 días si persisten lesiones), para un adulto de 60 kg le corresponderían 2 pastillas de 6 mgr de ivermectin, que es la presentación original. Considerado actualmente el tratamiento mas eficaz.

2.)  Albendazol: 
 
 La dosis es de 400 mgr dia por 3 a 4 dias seguidos. Se recomienda repetir a la semana 3  o 4 dias mas. Tratamiento muy útil en los niños, pues la presentación es también en suspension, aparte de las tabletas que son de 200 mgr.

3.) Tiabendazol: (drofen): 
 
Dosis 25 mg/kg dia, por 2-5 dias (promedio 3 dias). No disponible en Venezuela hoy dia.

TRATAMIENTO LOCAL:
 
- Criocirugia: (casi en desuso por ser muy dolorosa), consiste aplicar "nitrógeno liquido" desde afuera en el trayecto de la lesion, la larva muere por "enfriamiento".
 
- Formulas magistrales: que contienen albendazol o tinidazol para ser aplicadas externamente: la absorción percutanea de las misma, "envenena" el parásito y muere. 

TRATAMIENTO SINTOMÁTICO:

- Antibióticos: si hay infección secundaria.
 
- Antihistamínicos orales: Para controlar el prurito que puede ser intenso.
 
- Corticoides topicos: Para disminuir la inflamación y evitar infección secundaria. 
 
El tratamiento de la LARVA MIGRANS PROFUNDA VISCERAL y OCULAR., suele ser mas prolongado, 6 a 18 meses promedio. El tratamiento de la LARVA ocular puede incluir cirugía vitroretiniana, fotocoagulación por láser y medicación para evitar daño ocular.

CONCLUSIONES:

 - Instaurar tratamiento temprano para evitar secuelas organicas, principalmente en los casos VISCERALES y OCULARES.
 
- La LARVA MIGRANS CUTANEA, clásica es relativamente fácil de identificar y los tratamientos propuestos son altamente efectivos. 

- De modo pues que cuiden las lindas mascotas, llévenlas regularmente al veterinario y tengan cuidado cuando vayan a la playa y el campo para evitar esta enfermedad. 
 
 En las referencias conocerás la enfermedad y sus variantes, los agentes causales y las opciones terapéuticas

En el attach: la larva, el niño, la mascota, y otras más.

===================
Hello friends of to the net, DERMAGIC again with you. Today's topic THE CUTANEOUS LARVA MIGRANS SYNDROME AND PETS (DOGS AND CATS).  
 
We love pets, mainly the dogs and cats. But in  the feces (poop) of these beautiful animals there are some parasites  that can pass to the skin when we touch or ingest them. 

The favorite site to contract them is the BEACH or THE FIELD  where  our pretty pets make its  feces. Then we come and frankly we put some part of our body (mainly the foot) in contact with them, and the larva penetrates our skin directly from the feces causing the disease.

Also in homes where there are dogs and cats not controlled by the veterinarian. In short another disease where the man is accidentally contaminated by the animal.
Larva migrans cutanea pie.


Nowadays described in some publications as "the souvenir of travelers and tourists" who contract it during their vacations. Several parasites are the causal agents but the most common are: ANCYLOSTOMA CANNINUM and ANCYLOSTOMA BRAZILIENZE.

OTHER CAUSING AGENTS:

- Ancylostoma ceylanicum, A. tubaeforme (dogs and cats)

- Gnathostoma spinigerum (cats, dogs, pigs)

- Hookworm (dogs in Europe)

- Bunostomum phlebotomum (cattle)

- Pelodera strongyloides

- In rare cases, Ancylostoma duodenale, Necator americanus (human hookworms), and strongyloides stercoralis.


The  cutaneous larva migrans, is a superficial disease, the parasite lives in the superficial layer of the skin, making tunnels as it grows, also called "creeping eruption", but it is self-limited and with a good treatment disappears without leaving complications in the majority of cases.

CUTANEOUS LARVA MIGRANS presents a variant called MIGRATORY NODULAR PANICULITIS: it occurs when the larvae migrate deeper into the fat pad, forming migratory subcutaneous nodules, edema, and eosinophilia. The causative agents that produce this variant are:

- Gnathostoma spinigerum.

- Gnathostoma doloris.

- Gnathostoma hispidum.

VISCERAL LARVA MIGRANS:

There is another variant of LARVA MIGRANS, VISCERAL (DEEP) caused by other parasites such as Toxocara canis (dogs) and others. The parasite migrates to deep organs such as the VISCERAL CAVITY, EYES, BRAIN, MUSCLES, and others. This is more dangerous and can leave after-effects if not detected and treated promptly.

CAUSING AGENTS OF VISCERAL LARVA MIGRANS:

- Toxocara canis (dogs)

- Toxocara cati (cats)

LARVA MIGRANS TREATMENTS:

1.) Ivermectin:

Dose: 200 mcg/kg (0.2 mg/kg) as a single dose (can be repeated after 7-14 days if lesions persist). For a 60 kg adult, the dose would be: Two 6 mg ivermectin tablets, which is the original formulation. Currently considered the most effective treatment.

2.) Albendazole: 
 
The dose is 400 mg daily for 3 to 4 consecutive days. It is recommended to repeat the treatment for 3 or 4 more days a week. This treatment is very useful in children, as it also comes in suspension form, in addition to the 200 mg tablets.

3.) Thiabendazole (Drofen): 
 
Dosage: 25 mg/kg daily, for 2-5 days (average: 3 days). Not currently available in Venezuela.

LOCAL TREATMENT:

- Cryosurgery: (almost obsolete due to its very painful nature), consists of applying "liquid nitrogen" from the outside to the lesion. The larva dies due to "cooling."

- Magistral formulations: containing albendazole or tinidazole for external application: percutaneous absorption of the It "poisons" the parasite, and it dies.

SYMPTOMATIC TREATMENT:

- Antibiotics: if there is a secondary infection.

- Oral antihistamines: To control itching, which can be intense.

- Topical corticosteroids: To reduce inflammation and prevent secondary infection.

Treatment for deep VISCERAL and OCULAR larva migrans is usually longer, averaging 6 to 18 months. Treatment for ocular larva migrans may include vitroretinal surgery, laser photocoagulation, and medication to prevent eye damage.

CONCLUSIONS:

- Establish early treatment to avoid organic sequelae, especially in visceral and ocular cases.

- Classical cutaneous larva migrans is relatively easy to identify, and the proposed treatments are highly effective.

- So, take care of your lovely pets, take them to the vet regularly, and be careful when go to the beach and the countryside to avoid this disease.
