ABSTRACT
Tick paralysis (TP) occurs worldwide and is caused by a neurotoxin secreted by engorged female ticks that affects the peripheral and central nervous system. The clinical manifestations range from mild or nonspecific symptoms to manifestations similar to Guillain-Barré syndrome, bulbar involvement, and death in 10% of the patients. The diagnosis of TP is clinical. To our knowledge, there are no formal reports of TP in humans in South America, although clusters of TP among hunting dogs in Argentina have been identified recently. In this paper, clinical features of two cases of TP occurring during 1994 in Jujuy Province, Argentina, are described.
A paralisia por carrapatos (PC) ocorre mundialmente e é causada por uma neurotoxina secretada por carrapatos fêmea engolidores de sangue que afeta o sistema nervoso periférico e central. As manifestações clínicas variam de suave ou sintomas não específicos a manifestações semelhantes à síndrome de Guillain-Barré, envolvimento de bulbar, e morte em 10% dos pacientes. O diagnóstico de PC é clínico. A nosso conhecimento, não há nenhum relatório formal em seres humanos na América do Sul, embora grupos de PC entre cães de caça na Argentina, tenham sido identificados recentemente. Neste artigo, descrevo dois casos de PC ocorridos durante o ano de 1994 na província de Jujuy, Argentina.

Tick paralysis (TP) is a rare disease with rapid progression and potential fatal evolution. Immediately after the diagnosis, removal of all ticks from the body of the patient is mandatory. The present study reports for the first time a human case of the disease in Brazil. The patient had loss of muscle strength, decreased reflexes and marked palpebral ptosis. Six hours after removal of the last tick, the ptosis improved and on the following day, the patient had near total regression of the symptoms. This report emphasizes the possible presence of similar cases that should be promptly diagnosed and quickly treated. A new induction pattern for TP in humans associated with immature stages of ticks is also presented.

The Guillan-Barre syndrome [GBS] is characterized by the acute onset of rapidly progressive, symmetric muscle weakness with absent or decreased deep tendon reflexes. GBS is the most common cause of acute flaccid paralysis in childhood, with an incidence of 0.6-4 per 100000 Population per year. The clinical features are district and obtaining patient's history and conducting and examination generally lead to the diagnosis that can be confirmed by supportive laboratory tests and electrodiagnostic studies. The major considerations in differential diagnosis include transverse myelities, toxic neuropathy, tick paralysis, infantile butolism and myasthenia gravis. Although most, children with GBS have a relatively care monitoring. Immunomodulating treatment should be used for any child who loses the ability to walk

Tick paralysis is caused by a neurotoxin secreted by female tick. Characteristic initial manifestation is bilateral flaccid ascending paralysis similar to Guillain-Barr? syndrome. The predominant electrophysiological abnormality is a reduction in complex muscle action potentials. Here, we present a 62-year-old man who initially experienced a sudden biting pain on his scalp. Subsequently he developed bilateral lower extremity paralysis that ascended symmetrically involving the upper extremities. Within 2 weeks, the patient showed a full recovery without treatment.

En el presente trabajo presentamos las características clínicas y de laboratorio que se encontraron en dos pacientes en los que se hizo el diagnóstico de enfermedad de Lyme. Se hace una revisión somera del ciclo biológico y las características clínicas de los diferentes estadios en que se puede identificar al paciente con esta enfermedad. Se mencionan las técnicas de laboratorio útiles en el diagnóstico y la terapéutica actual del padecimiento. Enfermedad de Lyme

Se ha comprobado que en Panamá las garrapatas intervienen en diversos problemas de la salud humana y de los animales, no obstante, poca es la información que sobre dichos artrópodos y su ecología está a disposición del personal médico nacional. En este trabajo se exponen algunos conceptos generales sobre la biología de las garrapatas; y, asimismo, se describe someramente la epidemiología de las enfermedades que son transmitidas por ellas al ser humano en el país
