Occasionally worms are found in the female genital organs. More rarely, they are found in the ears and nose.
Nasal myiasis is the invasion of nasal cavities by fly larvae. Local tissue destruction is common and fatal complications can result from invasion of the central nervous system.
The parasites are quite mobile and their clinical signs and symptoms always appear suddenly. The main symptoms are a foreign-body sensation and itching in the throat, followed by cough and other respiratory and nasal manifestations such as nasal discharge, sneezing, laryngospasm, dyspnoea and stridor.
To treat pinworm infection, your doctor may recommend over-the-counter pyrantel pamoate or prescribe medication to all members of your household to prevent infection and reinfection. The most common prescription anti-parasite medications for pinworms are: Mebendazole.
Complications. Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals. The parasite can travel from the anal area up the vagina to the uterus, fallopian tubes and around the pelvic organs.
Ectopic pinworm infections have been described in many organs including the vagina, inguinal area, genitals, peritoneum, liver, oral cavity, lungs, and pelvis. There are even reported cases of appendicitis caused by impaction of the organ by pinworms. While death is very rare, recurrences are common.
Pinworm infection (called enterobiasis or oxyuriasis) causes itching around the anus which can lead to difficulty sleeping and restlessness. Symptoms are caused by the female pinworm laying her eggs. Symptoms of pinworm infection usually are mild and some infected people have no symptoms.
From the infection
Occasionally worms are found in the female genital organs. More rarely, they are found in the ears and nose. Rarely, worms invade the abdominal cavity, causing granulomas of the liver, ovary, kidney, spleen and lung. Chronic pelvic peritonitis and ileocolitis have been described.
Patient with nasal myiasis commonly presents with epistaxis, foul smell, and the passage of worms, facial pain, nasal obstruction, nasal discharge, headache, dysphagia, and sensation of foreign body in the nose [5.
Nasal worm in sheep and goats are the larvae or maggots of Oestrus ovis, which is the sheep bot fly. Nasal worm or nasal bots only develop to maturity in sheep and goats, and as such, do not pose a threat to cattle and other livestock, but only to sheep and goats.
Parasitic Infections
The adult parasite is found throughout the nasal passages and sometimes can reach the sinuses and middle ear by moving through the exudate in the Eustachian tubes. In common with other nasal parasites, Linguatula serrata acts as an irritant, causing sneezing, catarrhal inflammation, and epistaxis.
Rhinoviruses, influenza viruses, and parainfluenza viruses are the most common causes of sinusitis.
Treat with albendazole, mebendazole, or ivermectin; obstructions may require surgical or endoscopic extraction of the worms.
Along with the eggs, the worm also secretes a mucus that causes itching. If the eggs get stuck on the person's fingertips when they scratch, they can be transferred to their mouth or on to surfaces and clothes. If other people touch an infected surface, they can then transfer the eggs to their mouth.
Head lice and the human hair
Man is the only known host of this parasite. Although any part of the scalp may be colonized, lice favor the nape of the neck and the area behind the ears, where the eggs are usually laid.
Symptoms may include diarrhoea, tiredness and weakness, abdominal pain and weight loss. Some worms cause anaemia.
The medicine should start to work straight away but it may take several days to kill all the worms. It's important to take the medicine as a pharmacist or doctor tells you. Do not stop early if you have been told to take it for several days.
Although often asymptomatic, parasitic infections can lead to disruptions in mood, behavior and sleep – particularly in children with worms. The most common worm infection amongst Australian children is threadwork (pinworm, Enterobius vermicularis).
Pinworms or their eggs have occasionally been detected at other sites, such as the liver and lung. Rarer clinical manifestations include salpingitis, pelvic pain and the formation of granulomas in the peritoneal cavity.
There they can cause inflammation or damage. You can also have allergic reactions to these worms. Rarely, the larvae can stay in your throat area and that's when you may develop “tingling throat syndrome” and potentially a cough. How do you diagnose such a worm in your throat?
Chlorine dioxide gas inactivates pinworm eggs in a non-invasive and non-corrosive manner.
Habitat. The pinworm lives in the lower part of the small intestine, and the upper part of the colon. It is found worldwide and causes the common infection enterobiasis in humans. Unlike many other intestinal parasites, the pinworm does not usually enter the bloodstream or any other organs besides the intestines.
Once someone has ingested pinworm eggs, there is an incubation period of 1 to 2 months or longer for the adult gravid female to mature in the small intestine. Once mature, the adult female worm migrates to the colon and lays eggs around the anus at night, when many of their hosts are asleep.
