Encephalitozoonidae are microsporidia associated with human infections including hepatitis, encephalitis, conjunctivitis, and disseminated disease. Microsporidia produce a small resistant spore containing a polar tube which serves as a unique vehicle of infection. Polar tube proteins (PTPs) from Encephalitozoon hellem. Encephalitozoon (Septata) intestinalis, and Encephalitozoon cuniculi were purified to homogeneity by HPLC. By SDS-PAGE, the Mr of E. hellem PTP was 55 kDa, while the Mr of E. intestinalis and E. cuniculi PTP was 45 kDa. Polyclonal rabbit antiserum to these purified PTPs localized to polar filaments by immunogold electron microscopy and immunofluorescence, and demonstrated cross-reactivity by both immunoblotting and immunogold electron microscopy. These PTPs have similar solubility properties, hydrophobicity, and proline content to a 43-kDa PTP we have previously purified from Glugea americanus, a fish microsporidium. As the polar tube is critical in the transmission of this organism, further study of PTPs may lead to the development of new therapeutic strategies and diagnostic tests.

During the period from July 1, 1999 to September 30, 2000, 9 children with severe adenovirus infection were treated at Chang Gung Children's Hospital. The mean age was 22 months (range, 5-50 months). All of them had lower respiratory tract infections, which manifested as lobar or segmental pneumonia and pleural effusion. Eight (88.9%) of the 9 patients required intensive care and 4 of them required mechanical ventilation. Abnormal laboratory findings included leukocytosis, elevated C-reactive protein, anemia, and prolonged prothrombin time and partial thromboplastin time. Extrapulmonary complications included hepatitis (6 cases), encephalitis (3), conjunctivitis (3), periorbital ecchymosis (1), and coagulopathy (2). One patient died, resulting in a mortality rate of 12.5%. Follow-up at 3 months postdischarge, 5 patients (62.5% of survivors) had bronchiolitis obliterans and/or organizing pneumonia. Seven patients were infected by serotype 3 adenovirus, 1 patient by serotype 2, and another by serotype 11. In conclusion, the clinical, laboratory, and radiographic features of severe adenovirus infection may mimic bacterial infection. Rapid progression of the clinical course despite antibiotic therapy and the presence of unusual extrapulmonary symptoms are important clinical clues in the diagnosis of severe adenoviral infection.

By presenting this case report describing Parinaud's oculoglandular syndrome, we review the medical literature on its most frequent etiology: catscratch disease, a self-limited, systemic illness caused by a Gram-negative bacillus, Bartonella henselae, principally affecting children under 15 years of age. Typical symptoms include regional lymphadenopathy, fever, malaise, and fatigue, possibly with more severe complications such as splenomegaly, granulomatous hepatitis, and encephalopathy. Ocular manifestations may include follicular conjunctivitis, Parinaud's oculoglandular syndrome, neuroretinitis, optic neuritis, and chorioretinitis. Diagnosis is based on serologic tests, and when necessary, antimicrobial treatment can be considered.

Enteroviruses are members of Enterovirus genus of Picornaviridae family. On the basis of their pathogenesis and host range, most human enteroviruses are classified into one of three groups (Coxsackie's viruses, echoviruses and polioviruses). Some unclassified human enteroviruses may cause bronchitis (type 68), acute hemorrhagic conjunctivitis (type 70), meningitis and paralysis (types 70 and 71) and hepatitis (type 72 or hepatitis A virus). Enteroviruses can be propagate in primary cultures of human monkey kidney cells and in some cell lines such as HeLa, Vero and WI-38. Virions are small (22-30 nm diameters) containing ss RNA, monopartite and have icosahedra symmetry. The fast, high sensitive and specific detection of enteroviruses today is achieved by using of PCR (Polymerase chain reaction) method. But, PCR is so much more than just mixing reagents in a tube and running a thermal cycler. In each laboratory with PCR facilities, it is necessary to find optimal PCR conditions (performing of PCR optimization experiments). In this paper we presented results of PCR optimization for enteroviruses by using of poliovirus type 1(Sabin). Optimal obtained PCR parameters were: 2,5 mM MgCl2, dNTPs dilution 10(-1) and annealing temperature 50 degrees C, after 30 amplification cycles in Perkin Elmer 2400 thermal cycler.

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency caused by mutations in the gene for Bruton tyrosine kinase (BTK) that result in the deficient development of B lymphocytes and hypogammaglobulinemia. Because the disorder is uncommon, no single institution has had sufficient numbers of patients to develop a comprehensive clinical picture of the disorder. Accordingly, a national registry of United States residents with XLA was established in 1999 to provide an updated clinical view of the disorder in a large cohort of patients. A total of 201 patients were registered by 66 physicians. The estimated birth rate for the 10-year period of 1988-1997 was 1/379,000. Infection was the most common initial clinical presentation (85%), followed by a positive family history (41%) and neutropenia (11%). Although the average age of diagnosis was younger in patients with a positive family history (mean, 2.59 yr) than in patients with a negative family history (mean, 5.37 yr) (p < 0.001), only 34.5% of patients with a positive family history at the time of their birth were diagnosed before clinical symptoms developed-that is, based on family history alone. Seventy percent of patients had at least 1 episode of otitis, 62% at least 1 episode of pneumonia, 60% at least 1 episode of sinusitis, 23% at least 1 episode of chronic/recurrent diarrhea, 21% at least 1 episode of conjunctivitis, 18% at least 1 episode of pyoderma and/or cellulitis, 11% at least 1 episode of meningitis/encephalitis, 10% at least 1 episode of sepsis, 8% at least 1 episode of septic arthritis, 6% at least 1 episode of hepatitis, and 3% at least 1 episode of osteomyelitis. Fourteen of 201 (6.9%) patients were dead at the time they were entered in the Registry. However, in a prospective 4 /4-year follow-up of living patients, only 3/80 (3.75%) patients died. Causes of death included disseminated enterovirus infection (n = 6), pulmonary insufficiency (n = 5), adenovirus infection (n = 1), sepsis (n = 1), acquired immunodeficiency disease syndrome (AIDS) (n = 1), myocarditis (n = 1), hepatitis (n = 2), and stem cell transplantation (n = 1).

A 46-year-old woman presented with chronic fluctuated liver function impairment, Raynaud's phenomenon, digital gangrene, pulmonary hypertension, and intense pruritus within a period of 2 years. Laboratory investigations revealed antinuclear antibodies, anticentromere antibodies (ACA), hypergammaglobulinemia, lymphocytic infiltration of the liver parenchyma, and mild cholangitis. The associated symptoms included thyroiditis, conjunctivitis sicca, xerostomia, and polyarthralgia. There was no conspicuous sclerodactyly, calcinosis, or dysphagia. The symptoms were relieved with intravenous, as well as oral, methylprednisolone. This constellation of presentations, including chronic autoimmune hepatitis with mild cholangitis and pulmonary hypertension, suggested that the presence of serum ACA might indicate relentless visceral organ damage.

Kawasaki Disease is a small-to-medium-vessel vasculitis that preferentially affects children. Kawasaki Disease can occur in adults, but the presentation may differ from that observed in children. Typical findings in both adults and children include fever, conjunctivitis, pharyngitis, and skin erythema progressing to a desquamating rash on the palms and soles. Adults more frequently present with cervical adenopathy (93% of adults vs. 15% of children), hepatitis (65% vs. 10%), and arthralgia (61% vs. 24-38%). In contrast, adults are less frequently affected by meningitis (10% vs. 34%), thrombocytosis (55% vs. 100%), and coronary artery aneurysms (5% vs. 18-25%). We report a case of acute Kawasaki Disease in a 24-year-old man who presented with rash, fever, and arthritis. He was successfully treated with high-dose aspirin and intravenous immunoglobulin (IVIG). Our case highlights the importance of considering Kawasaki Disease in adults presenting with symptoms commonly encountered in a general medical practice.

An outbreak of chlamydiosis was diagnosed in hatchling and juvenile Indopacific crocodiles (Crocodylus porosus) on a crocodile farm in Papua New Guinea. The outbreak was characterised by high mortality with hepatitis and exudative conjunctivitis. The agent appears to have been introduced with live wild-caught crocodiles, which are purchased routinely by the farm. Improved quarantine procedures and treatment with tetracycline led to a rapid reduction of losses on the farm.

Exfoliative erythema of malnutrition is a collective term for skin lesions caused by a combination of multiple deficiencies in vitamins, microelements, essential fatty acids and amino acids. We report a 3-year-old Iraqi girl with malnutrition due to coexisting coeliac and Hartnup's disease. On admission to hospital, she presented with kwashiorkor, anaemia, hepatitis and hypoalbuminia. She had severe skin changes with erythema, desquamation, erosions and diffuse hyperpigmentation involving the whole integument, particularly the perioral area, trunk and legs. She also had angular cheilitis, glossitis, conjunctivitis and diffuse alopecia. After treatment with a high-protein gluten-free diet and supplementation with vitamins and microelements there was a rapid improvement in the skin lesions. The severity of the skin lesions in this case can be explained by the coexistence of two metabolic diseases causing complex malnutrition.

Adenoviruses (AdV) are important pathogens primarily associated to respiratory infections of children and military staff even though it is also associated to many clinical manifestations, such as cystitis, conjunctivitis, diarrhea, hepatitis, myocarditis, and encephalitis. The goals of this study were to detect and type acute respiratory disease associated AdV isolates among military trainees in a selected region without an evidence of an outbreak. Throat swab samples were obtained during February 2006-March 2006 period, from 180 military male trainees aged 20-29, who were presented with respiratory tract symptoms and an oral temperature of > or = 38.0 degrees C. All specimens were tested by HEp-2 cell culture and real-time TaqMan PCR with AdV specific primers and probes. Positive cell culture results, presented as AdV-specific cytopathic effects, were confirmed by real-time polymerase chain reaction (PCR). AdV subgroup differentiation were performed using conventional PCR assays with the primer set specific for subgroup B, C or E. Subgroup specific PCR products were restricted with Mspl enzyme in order to check whether they were specific or not. AdV positivity was detected in 8 (4.4%) samples by cell culture and in 9 (5.0%) by the real-time PCR. All culture positive samples were also positive by real-time PCR. Eight of the nine real-time PCR-positive specimens were found to be in the subgroup E (this group contains only AdV type 4) and the results were confirmed with restriction enzyme analysis. One isolate could not be typed with the available primers. These data indicated that both real-time TaqMan PCR and restriction enzyme analysis provide sensitive and specific tools for AdV detection and subgroup differentiation for throat swab specimens. It can be concluded that since the prevalence of AdV infections was low in the study group, AdV infections were not considered as a vaccine requiring health problem in Turkish armed forces, however, larger scale studies were needed to reach a more precise conclusion.
