ABSTRACT
Cysticercosis, a parasitic disease caused by larval form of Taenia solium, is a major health concern in the developing world. The encysted larval stage can affect any part of the body, but are most frequently detected in brain, eye, skeletal muscle and subcutaneous tissue. Most muscular cysticercosis are almost always associated with central nervous system involvement or with multiple intramuscular cysts or both. Here we report an unusual case of cysticercosis in right rectus muscle which was an isolated muscle involvement without any other systemic manifestation.

Parasitism in skeletal muscles and myositis are commonly observed during experimental Trypanosoma cruzi infection. The effect of T. cruzi infection on contractile properties of skeletal muscles in consecutive periods of the acute infection in BALB/c mice was studied. Albarrada strain (clone 4) which was isolated in Mexico and has demonstrated a high level of blood parasitemia and parasitism in skeletal muscles was used. Isolated strips of rectus abdominis muscle were subjected to direct electrical field in vitro. Alternatively, plantaris muscles were stimulated in situ through the sciatic nerve. The peak amplitudes of a single twitch and tetanus contractions were considered to estimate the mechanical properties of muscles. Histopathological analysis was performed to correlate functional changes with the evolution of tissue parasitism and tissue injury. Contractile properties of muscles were significantly attenuated during acute T. cruzi infection. The percentage of damaged muscles rather than the character of tissue pathology affected their contractile properties significantly.

A case of primary hydatid disease, a rare location, is presented. The patient was a 20 year old female who presented with complaining of painful mass in the right hypochondrium 2 months before presantation. This cyst was strongly adherent to the two layers of m.rectus abdominis fascias. It was completely removed. No other site of hydatid disease was found and the patient remained well postoperatively.
