The clinical characteristics consisted of spotted and striated leuconychia, dark spots and fragility of the nails. The mycology is.

Read the full review: Proper clinical diagnosis, laboratory workup, and adequate antifungal therapy are the standard of care for all forms of aspergillosis. A recent review on the epidemiology of onychomycosis due to Aspergillus species has shown that Aspergillus spp.

About 10 million cases of onychomycosis are attributable to Aspergillus species. The affected nail may have been previously subjected to trauma and is most often a toenail; peripheral vascular disease is occasionally implicated.

The risk of having Aspergillus onychomycosis among diabetics increases with age and duration of diabetes Wijesuriya et al. Aspergillus onychomycosis is seen more among individuals with occupational exposures such as vegetable vendors Banu et al. Some individuals diagnosed with onychomycosis due to Aspergillus spp.

Onychomycosis due to Aspergillus spp. Infection starts under the nail near the hyponychium where spores may have lodged or at the lateral nail folds, or on a diseased nail plate colonised by Aspergillus spp Moore and Weiss, Once the fungus starts to grow, the infection spreads back toward the cuticle.

It looks much the same as any fungal nail infection, discolouring the nail, causing it to become thick, distorted, and flaky Zaias et al. The fungus will not, however, spread to the surrounding skin like some other fungal causes of nail infection Banu et al.

Particular features suggestive of Aspergillus infection are a chalky, deep white nail with early involvement of the lamina and painful perionyxis without pus Gianni and Romano, The toenails are involved 25 times more frequently than fingernails Banu, There are 2 common patterns of disease: Variations of clinical presentations have been observed among the different Aspergillus spp.

For example, a study in India showed A. Distal-lateral subungual onychomycosis due to Aspergillus ochraceopetaliformis left ; mixed-pattern onychomycosis total dystrophic onychomycosis and superficial white onychomycosis due to Aspergillus candidus middle ; yellowish pigmentation of the nail plate with mild hyperkeratosis due to Aspergillus versicolor right.

Outbreaks in immu- nocompetent hosts are caused by ingestion of oocysts. Infectious oocysts are excreted in human feces, causing human-to-human transmission. Waterborne transmission of Infection may be asymptomatic in immunocompetent and immunosuppressed hosts. Diarrhea is typi- cally watery and nonbloody and may be associated with abdominal pain, nausea, fever, and anorexia. In immunocompetent hosts, symptoms usually subside in 1 to 2 weeks without therapy.

Nitazoxanide is approved for treatment of Cryptosporidium but to date has not been shown to be effective in HIV- infected patients. The best available therapy for these patients is antiretroviral therapy to reduce immune suppression.

Tinidazole and metronidazole are used to treat giardiasis and trichomoniasis, not cryptosporidiosis. Because most infections are asymptomatic, this may be an underestimate. Recent outbreaks in North American have been related to ingestion of wild game, particularly bear.

Heavy infections can cause enteritis; periorbital edema; myositis; and, infrequently, death. This infection, caused by ingesting Trichinella cysts, occurs when infected meat from pigs or other carnivorous animals is eaten. Laws that prevent feeding pigs uncooked garbage have been an important public health measure in reducing Trichinella infection in this country. Person-to-person spread has not been described.

The majority of infections are mild and resolve spontaneously. The organism can also be transmitted through the inges- tion of meat from dogs, horses, and bears. Recent outbreaks in the United States and Canada have been related to consumption of wild game, particularly bear meat.

During the first week of infection, diarrhea, nausea, and vomiting are prominent features. As the parasites migrate from the gastrointestinal GI tract, fever and eosinophilia are often present.

Larvae encyst after 2 to 3 weeks in muscle tissue, leading to myositis and weak- ness. Myocarditis and maculopapular rash are less common features of this illness. However, arctic Trichinella nativa larvae in walrus or bear meat are resistant to freezing.

Although both cause GI symptoms and Campylobacter causes fever , neither causes eosinophilia or myositis. Cytomegalovirus has varied presentations but none that lead to this presentation. The answers are D and B, respectively. Toxocara eggs are ingested and begin their life cycle in the small intestine.

They migrate to many tissues in the body. Staphylococci will not typically cause eosinophilia. Trichinellosis, caused by ingesting meat from carnivorous animals that has been infected with Trichinella cysts, does not cause hepatosplenomegaly and is uncommon without eating a suspicious meal.

Giardiasis is characterized by profuse diarrhea and abdominal pain without systemic features or eosinophilia. Cysticercosis typically causes myalgias and can spread to the brain, where it is often asymptomatic but can lead to seizures. The vast majority of Toxocara infections are self-limited and resolve without therapy.

Rarely, severe symptoms may develop with deaths caused by central nervous system, myocardial, or respiratory disease. Severe myocardial involvement manifests as acute myocarditis. In these patients, glucocorticoids are administered to reduce the inflammatory complications. Antihelminthic drugs such as albendazole, mebendazole, or praziquantel have not been shown conclusively to alter the course of visceral larval migrans. Metronidazole is used for infections caused by Trichomonas, not tissue nematodes.

The infection principally occurs in Southeast Asia and the Pacific Basin, although cases have also been described in Cuba, Australia, Japan, and China. Infective larvae are excreted in rat feces and ingested by land snails and slugs.

The larvae migrate to the brain, where they initiate a marked eosinophilic inflammatory response with hemorrhage. Clinical symptoms develop 2 to 35 days after ingestion of larvae, and the initial presentation typically includes headache indolent or acute , fever, nausea, vomiting, and meningismus.

The diagnosis usually relies on the pres- ence of eosinophilic meningitis and compatible epidemiology. There is no specific chemo- therapy for A. Glucocorticoids may reduce inflammation.

In most cases, cerebral angiostrongyliasis has a self-limited course with complete recovery. It also causes migratory cutaneous swellings or eye infections. It is also endemic in Southeast Asia and China and is usually transmitted by eating undercooked fish or poultry som fak in Thai- land and sashimi in Japan.

Trichinella murrelli and Trichinella nativa cause trichinosis in North America and the Arctic, respectively. Trichinella cara is the cause of larval migrans. Humans acquire Strongyloides when larvae in fecally contaminated soil penetrate the skin or mucous membranes. The larvae migrate to the lungs via the bloodstream; break through the alveolar spaces; ascend the respiratory air- ways; and are swallowed to reach the small intestine, where they mature into adult worms.

Adult worms may penetrate the mucosa of the small intestine. Many patients with Strongyloides are asymptomatic or have mild gastrointestinal symptoms or the characteristic cutaneous eruption, larval currens, as described in this case. Small bowel obstruction may occur with early heavy infection. Eosinophilia is common with all clinical manifestations. In patients with impaired immunity, particularly glucocorticoid therapy, hyperinfection or dissemination may occur.

This may lead to colitis, enteritis, meningi- tis, peritonitis, and acute renal failure. Bacteremia or gram-negative sepsis may develop because of bacterial translocation through disrupted enteric mucosa.

Because of the risk of hyperinfection, all patients with Strongyloides infection, even asymptomatic carriers, should be treated with ivermectin, which is more effective than albendazole.

Fluconazole is used to treat candidal infections. Mebendazole is used to treat trichuriasis, enterobiasis pinworm , ascariasis, and hookworm. Mefloquine is used for malaria prophylaxis. It resides in tropical and subtropical regions. In the United States, it is found mostly in the rural Southeast.

Transmission is through fecally contaminated soil. Most commonly, the worm burden is low, and it causes no symptoms. Clinical disease is related to larval migration to the lungs or to adult worms in the gastrointestinal tract. The most common complications occur because of a high gastrointestinal adult worm burden, leading to small bowel obstruction most often in children with a narrow-caliber small bowel lumen or migration leading to obstructive complications such as cholangitis, pancreatitis, or appendicitis.

Rarely, adult worms can migrate to the esophagus and be orally expelled. During the lung phase of larval migration 9—12 days after egg ingestion , patients may develop a nonproductive cough, fever, eosinophilia, and pleuritic chest pain. Meningitis is not a known complication of ascariasis but can occur with disseminated strongyloidiasis in an immunocompromised host.

Fluconazole is mostly used to treat Candida infections. Diethyl- carbamazine DEC is first-line therapy for active lymphatic filariasis. Vancomycin has no effect on nematodes. This is a nematode infection in which humans are an accidental host. It occurs hours to days after ingesting eggs that previously settled into the muscles of fish. The main risk fac- tor for infection is eating raw fish. Presentation mimics an acute abdomen.

History is critical because upper endoscopy is both diagnostic and curative. There is no medical agent known to cure anisakiasis. It is endemic throughout the tropics and subtropics, including Asia, the Pacific Islands, Africa, parts of South America, and the Caribbean. Lymphatic infection is common and may be acute or chronic.

Chronic lower extremity lymphatic infection causes elephantiasis. Definitive diagnosis requires demonstration of the parasite. Microfilariae may be found in blood, hydrocele, or other body fluid collections by direct microscopic examination. Polymerase chain reaction—based assays have been developed that may be as effective. In cases of acute lymphadenitis, ultrasound examination with Doppler may actually reveal motile worms in dilated lymphatics. Live worms have a distinctive movement pattern filarial dance sign.

Stool ova and parasite examination is not useful for demonstration of W. Albendazole, doxycycline, and ivermectin are also used to treat microfilarial infections not macrofilarial. There is growing consensus that virtually all patients with Wuchereria bancrofti infection should be treated, even if asymptomatic, to prevent lymphatic damage.

Many of these patients have microfilarial infection with subclinical hematuria, proteinu- ria, and so on. Albendazole and doxycycline have demonstrated macrofilaricidal efficacy. Combinations of DEC with albendazole, ivermectin, and doxycycline have efficacy in eradication programs.

The World Health Organization established a global program to eliminate lymphatic filariasis in using a single annual dose of DEC plus either alben- dazole non-African regions or ivermectin Africa. Praziquantel is used for treatment of schistosomiasis.

It is endemic to the rain forests of Central and West Africa. Loiasis is often asymptomatic in indigenous regions with recognition, as in this case, only with visualized macrofilarial migration. Angioedema and swelling may occur in affected areas. Diethylcarbamazine DEC is effective treatment for the macro- filarial and microfilarial stages of disease.

Multiple courses may be necessary. Albendazole and ivermectin are effective in reducing microfilarial loads but are not approved by the U. Food and Drug Administration. There are reports of deaths in patients with heavy loads of microfilaria receiving ivermectin. Terbinafine is the treatment for ringworm. Voriconazole is an antifungal with no activity against worms.

Whereas Schistosoma mansoni, Schistosoma japonicum, Schistosoma mekongi, There are reportedly up to million individuals infected with Schisto- soma. Figure IV shows the global distribution.

All forms of schistosomiasis are initiated by penetration of infective cercariae released from infected snails into fresh water. After entering the skin, the schistosome migrates via venous or lymphatic vessels to either the intestinal or urinary venous system, depending on the species. Katayama fever, acute schistosomal serum sickness—related to migration, may develop in 4 to 8 weeks. Eosinophilia is common in acute infection.

This has become a more common global health problem because travelers are exposed while swimming or boating in infected fresh water bodies. Chronic schistosomiasis depends on the species and the location of infection. The intestinal species are responsible for portal hyperten- sion.

Immunologic tests are available to diagnose schistosomiasis, and in some cases, stool or urine examination results may be positive. The major endemic countries for S. Approximately 4 to 8 weeks after exposure, the parasite migrates through the portal and pulmonary circulations. Because there is not a large enteric burden of parasites during this phase of the illness, stool study results may not be positive, and serology may be helpful, particularly in patients from nonendemic areas.

Praziquantel is the treatment of choice because Katayama fever may progress to include neurologic complications. Praziquantel remains the treatment for most helminthic infections, including schisto- somiasis. Chloroquine is used for treatment of malaria; mebendazole for ascariasis, hook- worm, trichinosis, and visceral larval migrans; metronidazole for amebiasis, giardiasis, and trichomoniasis; and thiabendazole for Strongyloides spp.

Hepatosplenomegaly, hypersplenism, and esophageal varices develop quite commonly, and schistosomiasis is usually associated with eosinophilia. The computed tomography CT scan shows a parenchymal cysticercus with enhancement of the cyst and an internal scolex arrow. The cyst represents larval oncospheres that have migrated to the central nervous system CNS. Infections that cause human cystercicosis result from ingestion of T. Autoinfection may occur if an individual ingests tapeworm eggs excreted in their own feces.

Cysticerci may be found anywhere in the body, but clinical manifestations usually arise from lesions in the CNS, cerebrospinal fluid CSF , skeletal muscle, subcutaneous tissue, or eye. Neurologic manifestations are most common, including generalized or focal seizures from surrounding inflammation, hydrocephalus from CSF outflow occlusion, or arachnoiditis. As shown in Table IV, neuroradiologic demonstration of a cystic lesion containing a characteristic scolex is absolute criteria for diagnosis of cysticercosis.

Intestinal infection may be detected by fecal examination for eggs. More sensitive enzyme-linked immunosorbent assay, polymerase chain reaction, and serologic testing is not currently commercially available. Treatment of neurocysticercosis after neurologic stabilization is with albendazole or praziquantel. Studies have shown faster resolution of clinical and radiologic findings compared with placebo.

Initiation of therapy may be associated with worsening symptoms caused by inflammation that is treated with glucocorticoids. CNS cystic lesions but without the visualized scolex are typical of toxoplasmosis in patients with advanced HIV infection and are treated with pyrimethamine and sulfadiazine.

However, in this case, the patient was documented HIV antibody negative, and the CT lesion was typical for cysticercosis. Viral testing for HIV would not be helpful because toxoplasmosis is seen in advanced cases, not acute infection. Echocardiography would be indicated for suspected staphylococcal or other bacterial endocarditis with systemic embolization.

ELISA, enzyme-linked immunosorbent assay. Modified from Del Brutto OH et al: Proposed diagnostic criteria for neurocysticercosis. Echinococcal cysts, most commonly in the liver followed by the lung, are typically slowly enlarging and cause symptoms because of space-occupying effects. Cysts are often inci- dentally discovered on radiologic studies.

Compression or leakage into the biliary system may cause symptoms typical for cholelithiasis or cholecystitis. Echinococcal cysts may be characterized by ultrasonography. Demonstration of daughter cysts within a larger cyst is pathognomonic. Serodiagnosis may be helpful in questionable cases for diagnosis of E. Small cysts may respond to medical therapy with albendazole or praziquantel. Percutaneous aspiration-injection-resaspiration PAIR therapy is recommended for most noncomplex nonsuperficial cysts.

Surgical resection is recommended for complex cysts, superficial cysts with risk of leakage, and cysts involving the biliary system. Albendazole therapy is generally administered before and after PAIR or surgical therapy. Choose the one best response to each question.
