Ascariasis and hookworm (ancylostomiasis) remain the most common intestinal nematodes in the world with significant economic, social, and medical impact. An understanding of the transmission and pathogenesis of ascariasis and hookworm are necessary to recognize their clinical manifestations and to manage the pulmonary sequelae of infection. Transmission occurs predominantly in the tropics and rural areas where there is suboptimal sanitation, personal hygiene, and education regarding these parasites. Ascariasis generally occurs through hand-to-mouth ingestion of agricultural products or food contaminated with parasite eggs. Hookworm is transmitted through larval penetration of the skin. Larval pulmonary migration generally is asymptomatic. However, symptomatic pulmonary disease may occur with fever, cough, chest pain, hemoptysis, dyspnea, and wheezing due to (1) Loffler's syndrome, (2) the effects of larval tissue migration, (3) airway reactivity or bronchospasm, (4) infectious bacterial complications from parasitic migration and associated aspiration, and rarely (5) chronic eosinophilic pneumonia, transdiaphragmatic penetration, or symptoms of upper airway obstruction. Clinical evaluation shows pulmonary opacities on chest radiograph, peripheral blood eosinophilia, and larvae in respiratory or gastric secretions. Symptomatic treatment may be necessary with bronchodilators and systemic steroids or antibiotics for bacterial complications. The drug of choice is mebendazole (Vermox) 100 mg twice a day for 3 days. Alternatives include a single dose of pyrantel pamoate (Antiminth) 11 mg/kg (maximum dose, 1 g) or albendazole (Zentel) 400 mg orally once. Invermectin (Mectizan) is available through the World Health Organization, and, in the United States, through the manufacturer on a compassionate-use basis. Ivermectin is as effective as currently available drugs against Ascaris but shows only partial efficacy against hookworms, which infest humans. Preventive measures, improvement of sanitary facilities, education, and school screening may be important in the endemic areas to control these parasitic infections.

Strongyloidiasis is a benign gastrointestinal infection. It can pass through the lungs and induce pulmonary strongyloidiasis. The suspicion of pulmonary involvement begins with clinical and chest radiographic features in the patients at risk. They are as follows: chronic lung diseases, age was 65 years, altered cellular immunity, and use of corticosteroids. Definitive diagnosis is made by identification of strongyloides in the secretion or tissue of the respiratory tract. We present 2 patients with pulmonary strongyloidiasis in this research. These 2 cases were patients with chronic obstructive pulmonary disease; both patients were more than 65 years old. They had the risk factors for severe strongyloides infection (advanced age, use of corticosteroids, an high serum cortisol level), worsening of pulmonary symptoms (e.g., dyspnea, cough, sputum production) and abnormal radiographic findings. Strongyloides stercoralis was found in the sputum and stool, and pulmonary strongyloidiasis was diagnosed. Mebendazole 100 mg twice daily was used and this eliminated the parasite from the stool in case 1, and from the sputum in case 2. Unfortunately, there was a relapse of parasite infection in case 1 and it also induced pulmonary strongyloidiasis. Finally, he died of respiratory failure. Since this disorder has a high relapse rate (15%), serial follow-up of stool and sputum is very important.

We report cases of Armillifer Armillatus infestation in three Nigerian adults within two and half years in our health facility. The first patient was a 70 year old farmer and a regular consumer of snake meat for over 50 years. He presented in February, 2014 for follow-up visit as he was a known systemic hypertensive patient. He was incidentally discovered to have multiple comma-shaped calcific lesions in the lungs and liver on a chest radiograph. These were better demonstrated on abdominal ultrasound and computed tomographic scans. He was asymptomatic. The second patient was a 42 year old male civil servant who presented in December 2015 with dry cough and right loin pain for five and three days respectively. His past medical history revealed that he had been treated previously for pneumonia. He has never eaten snake meat but consumed Alligator (Amphibious reptile) for many years but stopped about 12 years ago. Similar calcific lesions were also noted in his liver and lung parenchyma on chest radiograph and abdominal ultrasound scan. The third patient was an 80 year old man who presented in April, 2014 with dizziness and diminished urine output of one day duration. He was a farmer who has been consuming snake meat for many years, and has been on management for systemic arterial hypertension and prostatic hypertrophy. Chest radiograph and abdomino-pelvic ultrasound incidentally revealed multiple comma-shaped calcific lesions in the lungs and liver. The liver function test parameters were all within normal limits but the electrolytes were deranged and he was anaemic with a Packed Cell Volume of 27%. A diagnosis of Armillifer Armillatus infestation was made in these patients, and they were conservatively managed with Mebendazole. The third case was catherized and the deranged electrolytes were corrected. The first patient was lost to follow-up, whiles the second and third had no remarkable symptoms on subsequent follow-up visits.
