Cyclospora cayetanensis is an agent of emerging infectious disease, and a recognized cause of diarrhea in some patients. Also, the flagellated protozoan, Giardia intestinalis, induces a diarrheal illness of the small intestine. Cases of cyclosporiasis are frequently missed, primarily due to the fact that the parasite can be quite difficult to detect in human fecal samples, despite an increasing amount of data regarding this parasite. On the other hand, G. intestinalis can be readily recognized via the microscopic visualization of its trophozoite or cyst forms in stained preparations or unstained wet mounts. In this report, we describe an uncommon case of co-infection with G. intestinalis and C. cayetanensis in an immunocompetent patient with prolonged diarrhea, living in a non-tropical region of Turkey.

Cytomegalovirus (CMV)-associated esophageal ulcer is rare in immunocompetent infants. The presence of inclusion bodies and immunohistochemical staining for CMV in biopsy specimens obtained during esophagogastroduodenoscopy (EGD) indicate that such ulcers occur because of CMV infection. A 7-week-old female infant who experienced frequent vomiting and feeding intolerance was diagnosed with a massive CMV-associated ulcer in the distal esophagus. The ulcer improved after conservative treatment using proton-pump inhibitors; however, ganciclovir was not administered. In a follow-up EGD biopsy specimen, no CMV inclusion bodies were present, and immunohistochemical staining results for this virus were negative. The presence of CMV inclusion bodies indicates active viral replication. If persistent inclusion bodies or positive immunohistochemical staining for CMV is observed in follow-up biopsy specimens, ganciclovir may be used to treat CMV-associated esophageal ulcers.

Strongyloides stercoralis (SS) is an intestinal nematode that is mainly endemic in tropical and subtropical regions and sporadic in temperate zones. SS infection frequently occurs in people who have hematologic malignancies, HIV infection and in individuals undergoing immunosuppressive therapy. In this study, we report a 12year-old immunocompetent boy who was admitted to our hospital with acute abdomen. Laboratory evaluation showed strongyloidiasis, amebiasis and giardiasis. Clinical and laboratory findings immediately improved with albendazole therapy. Therefore, when diarrhea with signs of acute abdomen is observed, stool examinations should be done for enteroparasitosis. This approach will prevent misdiagnosis as acute abdomen. Complete clinical improvement is possible by medical therapy without surgical intervention.

Primary laryngeal candidiasis is rare in immunocompetent patients and is prone to confusion with early glottic carcinoma or leukemia. We experienced a case of 74-year-old man who has 3- month history of hoarseness. The pathologic diagnosis was laryngeal candidiasis. He was treated with antifungal agents for 4 weeks after vocal cord stripping under general anesthesia. After treatment, the patient had no candidiasis or discomfort with his voice. We report this case with a review of literature.

Ramsay Hunt syndrome with the complication of encephalitis or meningoencephalitis is rarely reported and uncommon in immunocompetent patients. The radiological manifestations of such cases usually involve the cerebellum and brainstem or exhibit the absence of any abnormality. We report a case of a 78-year-old immunocompetent man hospitalized with Ramsay Hunt syndrome, who later developed meningoencephalitis. The cerebrospinal fluid-study excluded other causes of meningoencephalitis, and the clinical diagnosis indicated varicella zoster virus meningoencephalitis. Magnetic resonance imaging revealed increased signal intensities in the bilateral temporal lobe, midbrain, and pons on T2-weighted imaging, and T2 fluid attenuated inversion recovery and contralateral asymmetric pachymeningeal enhancement. Contrast-enhanced T1-weighted imaging revealed ipsilateral facial nerve enhancement.

This report describes a case of coinfection of Sphingomonas paucimobilis meningitis and Listeria monocytogenes bacteremia in a 66-year-old immunocompetent female patient. The patient had undergone traditional procedures, including acupuncture, which possibly caused the coinfection. During treatment with susceptible antibiotics for bacterial meningitis, she developed hydrocephalus on the third day. Consequently, the patient recovered with a mild neurological deficit of grade 4 motor assessment in both upper and lower extremities at discharge. S. paucimobilis and L. monocytogenes are rare pathogens in developed countries, occurring only during environmental outbreaks. S. paucimobilis meningitis is rarely reported. Hence, the various presentations of S. paucimobilis meningitis and the antibiotic regimen for its treatment are hereby reported, in addition to a review of other similar reported cases. This case is a possible traditional procedure-related infection. Appropriate oversight and training should be emphasized regarding preventive measures of this kind of infection. A team approach with neurologists and neurosurgeons is imperative in treating patients with hydrocephalus-complicated meningitis.

Blunt trauma, drugs, infection, congenital anomalies of the pancreaticobiliary system, and multisystem diseases are the main causes of acute pancreatitis in children. Various viruses can cause acute pancreatitis, but varicella-induced pancreatitis is unusual and generally observed in adults or immunocompromised patients. We report a rare case of acute pancreatitis associated with varicella-zoster virus infection in a 6-year-old immunocompetent girl. The patient initially presented complaining of severe abdominal pain and repetitive vomiting. The patient had multiple cutaneous crusts that has been caused by preceding varicella infection and had elevated values of serum amylase and lipase. Abdominal ultrasonography demonstrated swelling of the pancreas and pancreatic duct dilatation, findings which were compatible with acute pancreatitis. The patient's clinical and laboratory abnormalities were completely normalized through conservative treatment consisting of fasting, total parenteral nutrition, and analgesic therapy.

Purpose: Studies on cytomegalovirus (CMV) infections in immunocompetent children are lacking, and minimal information is available in the medical literature on hepatic manifestations and complications of CMV. The aims of this study were to evaluate the clinical characteristics, laboratory data, and prognosis of children with CMV hepatitis, and to investigate its prevalence at a single medical center in Korea over a 10-year period. Methods: One hundred thirty-two children diagnosed with CMV infection based on specific markers (anti-CMV IgM, CMV polymerase chain reaction in blood and urine, or CMV culture of urine) were included in the study. Clinical and biochemical characteristics, immunological markers, and outcomes of hepatic CMV infection were determined. Results: The median age of patients (n=132) was 8.5 months (range, 14 days-11.3 years). Peak total bilirubin and alanine aminotransferase levels in serum ranged from 0.11-21.97 mg/dL, and 5-1,517 IU/L, respectively. Alanine aminotransferase remained elevated from 2-48 weeks. Jaundice was the most common clinical feature of hepatic CMV infection during infancy. The hematologic findings revealed anemia, leukocytosis, and monocytosis in CMV-infected patients. All participants recovered without administration of ganciclovir. Conclusion: In children with CMV hepatitis, fever was the most common symptom at presentation, and jaundice was the most common clinical feature of hepatic CMV infection in infants younger than 3 months of age. Hepatic CMV infection in immunocompetent children is often a self-limited illness that does not require antiviral therapy, as most patients in this study had favorable outcomes.

Background and Aim: The incidence of extra nodal non Hodgkin lymphoma (ENL) is rising throughout the world. However, data regarding ENL as a group is limited. The aim was to study the epidemiological and histomorphological trends of primary ENL (pENL) in India. Material and Methods: The biopsy materials from sixty eight patients with pENL (45 male, 23 female, M:F= 1.9:1), diagnosed over a five year period (2005-2009), were analysed and pathologically reclassified according to the World Health Organization (WHO) classification, 2008 criteria. Results: Primary extra nodal non Hodgkin lymphomas constituted 22.0% (68/308) of all non Hodgkin lymphomas (NHL). The mean age at presentation for pENL and primary nodal NHL was 43 years and 58 years, respectively with a male predilection (M: F=2:1). Central nervous system (CNS) constituted the most common extranodal site (20/68, 29.5%) followed by gastrointestinal tract (17/68, 25%), and nose/nasopharynx (8/68, 11.8%). Diffuse large B-cell lymphoma (DLBCL, not otherwise specified), extranodal marginal lymphoma of mucosa associated lymphoid tissue (MALT) type, and B cell NHL unclassified (U) were the three most common histological types observed. T-cell phenotype was rarely noted (4%). Follicular lymphomas and anaplastic large cell lymphoma, seen among nodal NHL, were absent at extra nodal sites. Majority (41/68, 60%) of the patients with pENL were immunocompetent and 55% were in stage I-II with favorable prognosis. Conclusion: Central nervous system was the most common site of ENL, followed by gastrointestinal tract. Majority of pENL occurred in immunocompetent hosts with a favorable prognosis.
