Diphyllobothriasis
Diphyllobothriasis is the infection caused by tapeworms of the genus '' Diphyllobothrium'' (commonly '' D. latum'' and ''D. nihonkaiense''). Diphyllobothriasis mostly occurs in regions where raw fish is regularly consumed; those who consume raw fish are at risk of infection. The infection is often asymptomatic and usually presents only with mild symptoms, which may include gastrointestinal complaints, weight loss, and fatigue. Rarely, vitamin B12 deficiency (possibly leading to anaemia) and gastrointestinal obstructions may occur. Infection may be long-lasting in absence of treatment. Diphyllobothriasis is generally diagnosed by looking for eggs or tapeworm segments in passed stool. Treatment with antiparasitic medications is straightforward, effective, and safe. Signs and symptoms Most infections (~80%) are asymptomatic. Infections may be long-lasting, persisting for many years or decades (up to 25 years) if untreated. Symptoms (when present) are generally mild. Manifestati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Diphyllobothrium
''Diphyllobothrium'' is a genus of cestoda, tapeworms which can cause diphyllobothriasis in humans through consumption of wikt:raw, raw or undercooked fish. The principal species causing diphyllobothriasis is ''D. latum'', known as the broad or fish tapeworm, or broad fish tapeworm. ''D. latum'' is a pseudophyllid cestode that infects fish and mammals. ''D. latum'' is native to Scandinavia, western Russia, and the Baltics, though it is now also present in North America, especially the Pacific Northwest. In Far East Russia, ''D. klebanovskii'', having Pacific salmon as its second intermediate host, was identified. Other members of the genus ''Diphyllobothrium'' include ''Diphyllobothrium dendriticum, D. dendriticum'' (the salmon tapeworm), which has a much larger range (the whole northern hemisphere), ''D. pacificum'', ''D. cordatum'', ''D. ursi'', ''D. lanceolatum'', ''D. dalliae'', and ''D. yonagoensis'', all of which infect humans onl ...

Vitamin B12 Deficiency
Vitamin B12 deficiency, also known as cobalamin deficiency, is the medical condition in which the blood and tissue have a lower than normal level of Vitamin B12, vitamin B12. Symptoms can vary from none to severe. Mild deficiency may have few or absent symptoms. In moderate deficiency, Fatigue, feeling tired, Headache, headaches, glossitis, soreness of the tongue, Aphthous stomatitis, mouth ulcers, breathlessness, Presyncope, feeling faint, Tachycardia, rapid heartbeat, low blood pressure, pallor, hair loss, decreased ability to think and severe arthralgia, joint pain and the beginning of neurological symptoms, including Paresthesia, abnormal sensations such as ''pins and needles'', numbness and tinnitus may occur. Severe deficiency may include symptoms of cardiomyopathy, reduced heart function as well as more severe neurological symptoms, including changes in reflexes, poor muscle function, memory problems, blurred vision, irritability, ataxia, decreased Anosmia, smell and Hy ...

Intestinal Mucosa
The gastrointestinal wall of the gastrointestinal tract is made up of four layers of specialised tissue. From the inner cavity of the gut (the lumen) outwards, these are the mucosa, the submucosa, the muscular layer and the serosa or adventitia. The mucosa is the innermost layer of the gastrointestinal tract. It surrounds the lumen of the tract and comes into direct contact with digested food (chyme). The mucosa itself is made up of three layers: the epithelium, where most digestive, absorptive and secretory processes occur; the lamina propria, a layer of connective tissue, and the muscularis mucosae, a thin layer of smooth muscle. The submucosa contains nerves including the submucous plexus (also called Meissner's plexus), blood vessels and elastic fibres with collagen, that stretches with increased capacity but maintains the shape of the intestine. The muscular layer surrounds the submucosa. It comprises layers of smooth muscle in longitudinal and circular orientation that als ...

Cholecystitis
Cholecystitis is inflammation of the gallbladder. Symptoms include Right upper quadrant (abdomen), right upper abdominal pain, pain in the right shoulder, nausea, vomiting, and occasionally fever. Often gallbladder attacks (biliary colic) precede acute cholecystitis. The pain lasts longer in cholecystitis than in a typical gallbladder attack. Without appropriate treatment, recurrent episodes of cholecystitis are common. Complications of acute cholecystitis include gallstone pancreatitis, common bile duct stones, or cholangitis, inflammation of the common bile duct. More than 90% of the time acute cholecystitis is caused from blockage of the cystic duct by a gallstone. Risk factors for gallstones include combined oral contraceptive pill, birth control pills, pregnancy, a family history of gallstones, obesity, diabetes, cirrhosis, liver disease, or rapid weight loss. Occasionally, acute cholecystitis occurs as a result of vasculitis or chemotherapy, or during recovery from major tr ...
