[Case report: Two patients with eye worm and recurrent swelling of the extremities].

We report two cases of Loa loa (eye worm) infection in Iceland; the former in a 35-year-old woman born in Africa but living in Iceland for several years; the latter in a 31-year- old woman who had traveled in Africa. Both women sought medical attention due to discomfort in one eye. On exami-nation a worm was noted in both cases, moving under the conjunctiva, 3 cm in length and 0.5 mm in diameter. Both patients also had symptoms from the extremities; episodic swelling and itching in the former case, and muscle pain in the latter. Both patients were diagnosed with loiasis with Calabar swellings of the extremities and were successfully treated with albendazole and diethylcarbamazine. Increased awareness is needed for infections which previously have been rare in the Nordics.

Cytological diagnosis of microfilaria at unusual sites in clinically unsuspected cases: some rare presentations of filariasis.

Filariasis is a major concern, particularly in endemic regions. The majority of patients harbouring the parasite may remain asymptomatic for years. Here, we present six patients who were sent for routine cytological examination to rule out neoplastic pathology, in whom cytology identified filarial infestation. The main purposes of our paper are to highlight the importance of fine needle aspiration cytology (FNAC), a cheap and quick investigation to detect the microfilaria from tissue swelling and body fluids, and to point out that clinicians practising in endemic regions should always consider filarial infestation in patients presenting with longstanding swelling.

Immunomodulatory activity of Buchholzia coriacea seed methanol extract on Trypanosoma brucei brucei infected mice.

CONTEXT: The seeds of Buchholzia coriacea Engler (Capparaceae) are used in Eastern Nigeria to treat feverish conditions, and to treat malaria and sleeping sickness that cause fever. OBJECTIVE: The current study assesses the immunomodulatory activity of Buchholzia coriacea seed extract on Trypanosoma brucei brucei infected mice. MATERIALS AND METHODS: Delayed hypersensitivity reaction, humoral antibody response and in-vivo leucocyte mobilization tests were assessed in three different experiments to determine the effect of the extract on immune response. Seventy-five (75) mice (25 mice per experiment) were used for the study and were each infected with 1.00 × 106 trypanosomes intra-peritoneally. Groups A, B and C were given 250, 500 and 1000 mg/kg of the extract, respectively, group D received 7.5 mg/kg body weight of levamisole and group E was the control. Sheep RBCs were used as antigen. RESULTS: The acute toxicity tests did not cause clinical signs or death within 24 h post treatment at all the doses tested. The extract inhibited delayed hypersensitivity reaction by 20.9 and 20.8% at 250 and 500 mg/kg, respectively, while at 1000 mg/kg, the paw size increased (-101.9%) when compared with the control. The extract elevated the antibody titre from 1.60 ± 0.40 for control to 8.00 ± 3.58 for 500 mg/kg group. The extract increased in total leucocytes counts. DISCUSSION AND CONCLUSION: The extract has a very wide safety margin and was able to improve immune response. The results of the present study showed that Buchholzia coriacea seed methanol extract possesses immunostimulatory activity on trypanosome-infected mice.

Bug Smash, Bug Splash: A Case Report of an Unusual Transmission of American Trypanosomiasis with a Brief Review of the Literature.

BACKGROUND Chagas disease is a chronic parasitosis transmitted by the inoculation of infected triatomine feces into wounds or conjunctival sac, transfusion, congenitally, organ transplantation, and ingestion of contaminated food. The disease is classified into an acute and chronic phase; the latter is a life-long infection that can be asymptomatic or progress to cardiac or digestive complications. CASE REPORT We report a case of acute-phase Chagas disease, transmitted by the splash of gut content from an infected triatomine into the conjunctival mucosa. CONCLUSIONS The diagnosis of Chagas disease is made by the direct visualization of the parasite in blood smears during the acute phase of the disease; during the chronic phase of the disease the diagnosis is made by the detection of IgG antibodies. Parasitological cure can be achieved in up to 80% of the cases in acute phase of the disease, in contrast with less than 30% during the chronic phase.

Toxoplasmosis presented as a submental mass: a common disease, uncommon presentation.

Submental mass secondary to toxoplasmosis is not common in clinical work. A diagnosis of toxoplasmosis is rarely considered by physicians. Here we describe a 50-year-old woman presented with a progressive, painful, submental and left neck swelling for 1 month. After having obtained an insufficient evidence from the fine-needle biopsy, the patient finally received an excisional biopsy which highly indicated the possibility of lymphadenopathy consistent with toxoplasmosis. Diagnosis of toxoplasmosis was finally established by a combination of the pathological criteria, together with the positive serological finding. According to review the clinical presentations, pathological characteristics, diagnostic standard and treatment of this disease, the article aims to remind otolaryngologists who are evaluating a neck mass should be aware of the infectious cause of lymphadenopathy and the possibility of toxoplasmosis.

A 29-year-old man with an unusual cause of an abscess.

A 29-year-old man with no medical history presented with a left scalp abscess and left temporal oedema. He was initially started on treatment for community acquired Methicillin-resistant Staphylococcus aureus with sulfamethoxazole and trimethoprim. Over the next 2 weeks, his swelling improved; however, he continued to have localised swelling and drainage from the area. Eventually, larvae of a botfly were removed from his scalp, and his symptoms resolved.

[What is your diagnosis? A "fat arm". Onchocerciasis]. / Une histoire de "gros bras".

We report a case of edema of the right forearm with pruriginous papules and eosinophilia in the blood. The patient had lived in a forested area of Cameroon. The clinical, laboratory, and geographical findings led to a diagnosis of onchocerciasis, despite the absence of microfilaments on skin biopsy samples. The patient was successfully treated with ivermectin and doxycycline.

A rare manifestation of cysticercosis infestation.

There are many causes of urticaria, which may vary from infections to malignancy. Among the infections, infestations by cysticercosis (larval stage of the tapeworm called Taenia solium) is an important cause. The present report is of forty four years old female who presented with urticaria and swelling on face. The swelling was later diagnosed as cysticercosis by noninvasive ultrasonography. The urticaria subsided after the treatment of cysticercosis. We report this case for rarity of its presentation.
