===================
Hello friends of the Net, DERMAGIC again with you. Today a quite interesting NON DERMATOLOGIC topic. THE CAT'S CLAW AND THE SHARK CARTILAGE:

 
Uña de Gato

 
THE CAT'S CLAW is not in fact the "fingernail of a cat", it is a plant from PERU called UNCARIA TOMENTOSA, to which have been  discovered some beneficent actions for the organism, being able to be used in: arthritis, rheumatism, bursitis, gout, immunologic deficiencies, intestinal permeability, intoxications, it inhibits the platelet aggregation and it acts as anti-inflammatory.in:  
 
USES OF CAT'S CLAW (UNCARIA TOMENTOSA):

1.) arthritis, osteoarthritis.
 
2.) rheumatism.
 
3.) bursitis.
 
4.) gout.
 
5.) immunologic deficiencies.
 
6.) intestinal permeability.
 
7.) intoxicationS.
 
8.) inhibits the platelet aggregation.
 
9.) anti-inflammatory.
 
10.) Anti-cancer activity (breas cancer, lung cancer, thyroid cancer).
 
11.) aids.
 
12.) Diabetes and others.

CAT'S CLAW CONCLUSIONS:

CAT'S CLAW (UNCARIA TOMENTOSA) is used today for various conditions, including:

It is a
NATURAL ANTI-INFLAMMATORY, used as a complementary treatment for arthritis and osteoarthritis.

It also
MODULATES and STRENGTHHENS THE IMMUNE SYSTEM, stimulating the production of white blood cells and preventing immunosuppressive states.

It has an
ANTIOXIDANT effect, due to its alkaloid and proanthocyanidin content, protecting cells from oxidative stress caused by free radicals.

Use in
INFECTIONS: It is used to prevent and treat mild bacterial infections and infections of the urinary, digestive, and respiratory tracts, due to its immune-boosting effect.

Other uses: Relief from chronic diseases such as gastritis, rheumatism, fibroids, polycystic ovary syndrome, support in healing and cell regeneration, 
 
Which demonstrate from this plant native from the Peruvian Amazon its usefulness today as anti-inflammatory and anti-tumor effects.

 
Cartilago de Tiburon

 
THE SHARK CARTILAGE is not left behind, as many studies have shown that its components have been used in conditions such: he has effects scientifically proven ANTI-TUMOR and ANTI-ANGIOGENESIS activities, its use has even been suggested in PSORIASIS (reference D). Other effects include: anti-inflammatory, analgesic, and suppression of atherogenesis.:  

USES OF SHARK CARTILAGE:

1,) ANTI-TUMOR-CANCER (tumor growth).
 
2.) ANTI ANGIOGENESIS (atherosclerosis, suppression of atherogenesis, TROMBOSIS).
 
3.) PSORIASIS.
 
4.) anti-inflammatory.
 
5.) analgesic.
 
6.) hemodialysis.
 
7.) fibrosis.
 
8.) viral and protozoan infections.
 
9.) hyperglycemia and others. 

CONCLUSIONS OF SHARK CARTILAGE:

Currently, SHARK CARTILAGE has its best effects on joints and
OSTEOARTHRITIS. Supplements containing shark cartilage (due to its chondroitin and collagen content) have been shown to be effective in reducing joint pain, and also have analgesic and anti-inflammatory effects.

It has also been tested in
PSORIASIS to reduce scaling and itching, but the results are controversial.

Regarding its anti-angiogenesis effects, there is a product called
NEOVESTAT or AE-941, a shark cartilage extract that has been studied in CANCER, for its effect on reducing blood vessel formation in tumor lesions. However, it is not approved as a therapy for this condition, and the results of the studies are controversial.

Thus, the greatest benefit of this natural medicine is in
JOINT HEALTH, and it is used today by many athletes as a supplement to maintain and improve joint health. 
 
 SUMMARY:
 
In these references you will know the chemical components of UNCARIA TOMENTOSA (CAT'S CLAW) and SHARK CARTILAGE and their beneficial effects on different diseases...So

The really TRUTH is that these products today in day they are a truthful sample that that these ALTERNATIVE medicines are occupying an important place in our SCIENTIFIC WORLD.

Greetings to all !

EL SÍNDROME DE LARVA MIGRANS CUTÁNEO Y LAS MASCOTAS.THE CUTANEOUS LARVA MIGRANS SYNDROME AND PETS /


 El síndrome de Larva Migrans Cutáneo y las mascotas (perros y gatos). !!! 


 The Cutaneous Larva Migrans Syndrome and pets (dogs and cats). !!! 


The  cutaneous larva migrans syndrome

Actualizado 2025

 

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

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.

So take care of the cute pets, take them regularly to the veterinarian and be careful when go to the beach and the countryside or field to avoid this disease!

In the references you will know the disease and its variants, the causal agents and the therapeutic options

Hello friends of the network, DERMAGIC is back with you again. Today's topic: SERENOA REPENS VS FINASTERIDE in ANDROGENIC ALOPECIA.

When the FINASTERIDE molecule was launched on the market, perhaps it was not thought that a medicine with similar or identical characteristics already existed, with the only difference being that this one is a plant.

SAW PALMETTO BERRIES, better known as SERENOA REPENS or SABAL SERRULATA, have been shown through scientific studies to be useful for both hair loss and Benign Prostatic Hyperplasia (BPH).

If we examine these bibliographic references carefully, we find the following:

1.) It has the same properties as FINASTERIDE in reducing prostate symptoms, perhaps not as potent as FINASTERIDE, but still useful.

2.) It inhibits isoenzymes 1 and 2 in the prostate.

3.) It has anti-inflammatory effects on the prostate.

4.) It lowers DHT (dihydrotestosterone) levels, which is responsible for Androgenetic Alopecia, because it inhibits 5-alpha reductase.

5.) It has been used topically and orally against 
Androgenetic Alopecia.

6.) And it obviously has fewer side effects than FINASTERIDE.

With these main characteristics, we must consider that

1.) Saw palmetto also has effects like FINASTERIDE against 
Androgenetic Alopecia.

2.) These two medicines, one NATURAL
(SERENOA REPENS = SABAL SERRULATA), the other CHEMICAL (FINASTERIDE), boths are useful in Prostatic Hyperplasia, improving the symptoms of enlargement, because both have been proven to inhibit the 5-alpha reductase enzyme, decreasing DHT levels.

3.)
SAW PALMETTO or SERENOA REPENS (SABAL SERRULATA) is now considered an ANTI-ANDROGENIC herb.

One of the reasons you might want to use SERENOA REPENS for the treatment of 
Androgenetic Alopecia, is to avoid the SIDE EFFECTS OF FINASTERIDE, primarily sexual dysfunction.

On the other hand, FINASTERIDE has been tested TOPICALLY, with good results for both 
Androgenetic Alopecia in men and HIRSUTISM in women, thus avoiding the effects of sexual dysfunction.

However, its commercial presentation was officially launched in November 2024 under the name
FINASTOPIC, from the ISDIN laboratory. Although its topical use has been studied since the 2010s.

In my opinion, finasteride is a great molecule for the treatment of androgenetic alopecia and benign prostatic hyperplasia (BHP). However, for those who wish to use or try Serenoa repens as a natural therapeutic alternative, this is a valid option.

Finally: A study was conducted that showed that KETOCONAZOLE shampoo locally reduces DHT. It could be used in conjunction with FINASTERIDE or SERENOA REPENS for 
Androgenetic Alopecia (reference 60).

I remind you that there is another molecule similar to FINASTERIDE called
DUTASTERIDE. Unlike dutasteride, this one, in addition to being presented in tablets, also comes in ampoules for local infiltration into the scalp. However, IT HAS NOT BEEN OFFICIALLY APPROVED for use in Androgenetic Alopecia, but widely used for its beneficial effects demonstrated in published articles.

==================
Hola Amigos de la red, DERMAGIC de nuevo con ustedes, El tema de hoy: SERENOA REPENS VS FINASTERIDE en ALOPECIA ANDROGÉNICA. 
 
Cuando la molécula FINASTERIDE fue lanzada al mercado quizá no se pensó que ya existía una medicina con similares o iguales características, con la única diferencia que esta es una planta.
 
LAS CEREZAS O BAYAS DEL SAW PALMETTO, mejor conocida como SERENOA REPENS o SABAL SERRULATA,  la cual ha demostrado a través de estudios científicos que es útil tanto en la caída del cabello como la Hiperplasia Prostatica Benigna (BHP). 

Si examinamos bien estas referencias bibliográficas nos encontramos con lo siguiente:  


LA SERENOA REPENS:  

1.) Tiene iguales propiedades al FINASTERIDE en disminución de la sintomatología prostática, quizá no tan potente como el FINASTERIDE, pero si es útil. 

2.) INHIBE LAS izoenzimas 1 y 2 a nivel de la próstata. 

3.) Tiene efectos antiinflamatorios a nivel prostático. 

4.) Disminuye el nivel de la DHT (dihidrotestosterona), la responsable de la Alopecia Androgénica porque INHIBE la 5 alfa-reductasa. 

5.) Ha sido utilizada en forma TOPICA como oral contra la Alopecia Androgénica.

6.) Y obviamente tiene menos efectos secundarios que el FINASTERIDE.  


Con estas característica principales debemos pensar que  

1,) LA SERENOA REPENS también tiene EFECTOS como el FINASTERIDE contra la Alopecia Androgénica. 

2.) Estas dos medicinas, una NATURAL (EL SAW PALMETTO=SERENOA REPENS=SABAL SERRULATA), otra QUÍMICA (FINASTERIDE) son útiles en la hiperplasia prostática mejorando los síntomas del agrandamiento, porque se comprobó que ambas inhiben la enzima 5 alfa reductasa disminuyendo los niveles de DHT. 

3.) El SAW PALMETTO o SERENOA REPENS (SABAL SERRULATA), hoy en dia   es considerada una planta ANTI-ANDROGENOS. 

Una de las razones que te puede conducir a utilizar LA SERENOA REPENS para el tratamiento de la Alopecia Androgénica, es evitar los EFECTOS SECUNDARIOS DEL FINASTERIDE, principalmente la disfunción sexual.

Por otra parte el FINASTERIDE ha sido probado en forma TOPICA, con buenos resultados tanto en la Alopecia Androgénica  en hombres, como el HIRSUTISMO en las mujeres, evitando asi los efectos de la disfunción sexual. 
 
Pero su presentación comercial fue oficialmente lanzada al mercado en Noviembre del 2024 con el nombre de FINASTOPIC, del laboratorio ISDIN, aunque su uso tópico se viene estudiado desde la decada del 2010.
 
 
En mi opinion EL FINASTERIDE ES una gran MOLÉCULA para el tratamiento de la Alopecia Androgénica y la Hiperplasia Prostatica Benigna,(BHP), pero aquellos que desean usar o probar la SERENOA REPENS como alternativa terapéutica naturista, esta valida la opción. 

Para finalizar: Se hizo un estudio donde se comprueba que el champú de KETOCONAZOLE a nivel local disminuye la DHT, el cual podría usarse en conjunto con FINASTERIDE o SERENOA REPENS, en la Alopecia Androgénica  (referencia 60) 

 Les recuerdo que existe otra molécula similar al FINASTERIDE denominada DUTASTERIDE, la cual a diferencia de esta ultima, ademas de presentación en tabletas, viene en ampollas para infiltración local en el cuero cabelludo, mas NO HA SIDO APROBADA OFICIALMENTE para su uso en la Alopecia Androgénica, pero utilizado ampliamente por sus efectos beneficiosos demostrados en articulos publicados. 
 
El DUTASTERIDE conocido con el nombre comercial de AVODART fue aprobado por la FDA para su uso en la Hiperplasia Prostatica Benigna (HPB), al i¡gual que el FINASTERIDE, Pero como dijimos NO APROBADO PARA LA ALOPECIA ANDROGENICA. 
 
USO OFF LABEL: (Fuera de etiqueta): en la ALOPECIA ANDROGENICA:  
 
El DUTASTERIDE es usado ampliamente en esta condicion, aun NO ESTANDO APROBADO OFICALMENTE por LA FDA, para la Alopecia Androgenica, los medicos lo recetan y aplican localmente, basandose en la evidencia de estudios clinicos publicados que demuestran su efectividad. 

 En estas referencias los hechos... 

Saludos a todos !!!
