Korean Hemorrhagic Fever was recognized during the Korean War (1950-1953) and intensive studies have been done especially in early 1950's. However, the etiologic agent, vector, and reservoir are not known conclusively. The occurrence has two peak seasons in spring and autumn, and is not limited to military personnel in front lines but also civilians are attacked. Still the study is going on.

Extra-nodal malignant lymphoma is often characterized by a lack of typical symptoms and positive results of auxiliary examinations, which make diagnosis difficult. In some cases, fever can be the only clinical manifestation. For the lymphoma patients presenting with persistent fever with a duration over 3 weeks, characteristics of fever including time of fever attack, fever type and effects of drugs may have significant value in the diagnosis, especially in the early stage of the disease or in rare cases.

OBJECTIVETo investigate the pathogenic and clinical presentation and laboratory tests of bullous rash in hand, foot and mouth disease (HFMD) in Xi'an from January 2013 to December 2014 by retrospective analysis.

METHODA total of 224 specimens were collected from clinically diagnosed HFMD cases who were characterized by widespread mucocutaneous bullous reactions in Xi'an Children's Hospital from January 2013 to December 2014, the identification and subtyping of the isolates were conducted with real-time fluorescent quantitative RT-PCR. A retrospective analysis was performed to analyze the clinical presentation, laboratory tests and late follow-up problems of the HFMD.

RESULTIn the clinically diagnosed HFMD cases who were characterized by widespread mucocutaneous bullous reactions, 207 were caused by coxsackievirus A6 (CA6), accounting for 92. 4% of all cases with bullous, 4 were caused by enterovirus 71 (EV71), accounting for 1.8%, 10 were caused by coxsackievirus A16 (CA16), accounting for 4. 5%; 4 cases were negative for these viruses. In the cases positive for intestinal virus-nucleic acid, 130 were male, 90 were female; male to female ratio was 1. 44: 1, 203 were <5 years old, accounting for 92. 3%. Leukocytosis was found in 75 cases (34. 1%); high-sensitivity C-reactive protein (hsCRP) increased in 200 cases (90. 9%); elevated myocardial enzyme CK-MB was found in 35 cases (15. 9%), alanine aminotransferase increased in 15 cases (6. 8%); 187 cases had fever (85. 0%). None of the cases had serious complications such as encephalitis or myocarditis. In the course of the critical phase bullous rash or large vesicle-like changes, obvious itching, and facial rash appeared. After the fluid in the bullae was absorbed or the bullae ruptured or became ulcerated, scar formation and large areas of exfoliation occurred, with no effusion on the newly formed epithelium in the base, without significant pigmentation on later follow-up. In the late follow up process, 52 cases in CA6-positive patients (25. 1%) developed onychomadesis within 2-4 weeks after onset, 1 to 8 nails, an average of 4. 3 fell off, new nails grew, the nail bed showed no structural abnormalities and hyperplasia after falling off, the surface was smooth, had no hypertrophy, left no sequelae.

CONCLUSIONThe pathogen in HFMD characterized by widespread bullous reactions was mainly the CA6, this kind of HFMD was mainly mild type, with significant itching, later the bullae may have scar formation and skin exfoliation, in some cases onychomadesis may occur.

OBJECTIVETo present six cases of Brucella infection in children, analyze the characteristics of the disease, diagnostic and therapeutic process.

METHODThe clinical manifestations, laboratory test results and diagnostic process of 6 confirmed cases of brucellosis seen between 2011-2012 were retrospectively analyzed and domestic and foreign literature was reviewed.

RESULTAll the 6 children had a history of either exposure to, travelling to endemic area, or consuming infected lamb/beef. After the relevant examinations for these children, either positive etiologic or serologic evidence of brucellosis infection was obtained. The main clinical manifestation was fever in all cases, the peak body temperature was 37.5-38.0 °C in 3 cases, 38.1-39.0 °C in 2 cases, 39.1-41 °C in 1 case. Except for 1 case whose fever type was undulant fever, all the rest had irregular fever.Joint pain existed in 3 cases, orchitis in 1 case, cervical lymphadenopathy in 3 cases, hepatosplenomegaly in 2 cases, and impaired liver function in 4 cases. The Brucella agglutination test was positive in 5 cases. The blood culture was positive for all cases. In 4 cases the sulfamethoxazle and rifampicin were used for treatment, 1 case was treated with rifampicin and erythromycin, parents of 1 case refused to use the drug. The "brucellosis in children" was used to search literature at Wanfang database, Pubmed database for literature of recent 10 years, and a total of 13 articles including 15 cases were retrieved. All the patients had fever, 6 cases had joint swelling and pain, 10 cases had hepatosplenomegaly, 6 cases had cervical lymphadenopathy, 4 cases were complicated with central nervous system infection. Brucella agglutination test was positive in 9 cases and blood culture was positive for Brucella infection in all cases.

CONCLUSIONChildhood Brucella infections are usually presented with various clinical manifestations, and are often accompanied by symptoms of systemic infection. For fever of unknown origin, one should include tests associated with brucellosis and pay special attention to differential diagnosis against other diseases.

The authors analysed bone marrow findings of sixteen cases of culture proven typhoid fever to reveal the pathologic changes according to the disease stage. The most frequent finding was chronic granulomatous inflammation (eight cases). Infection (bacteria) associated hemophagocytic syndrome (four cases), reactive marrow (two cases), and non specific findings (two cases) were also encountered. Granulocytic hyperplasia with hemophagocytosis appeared at the early stage and was followed by infection (bacteria) associated hemophagocytosis and granuloma in proliferative stage. In lysis (late) stage, granulomatous inflammation was noted. However, resolution of granulomatous inflammation was not distinct. Some nuclear debris and phagocytosis were remarkable in well-formed granulomas. Thrombocytopenia was the most remarkable peripheral blood finding at the time of biopsy. Anemia, leukopenia, and pancytopenia were also observed in descending order.

Since the early part of the twentieth century, many authors have claimed that eosinophilia is found in the nasal secretions and blood of patients with allergic diseases. This observation has now become an established fact, and recent evidence based on extensive investigation, suggests that the eosinophil may play an active role in allergic disease. Thus, we report changes in nasal eosinophils in a group of nasal allergy patients treated by specific hyposensitization. The following results were obtained; 1. Eosinophilia was noted in 52.8 percent of untreated nasal allergy patients. 2. The eosinophilic count was gradually decreased with increasing S.D.V.(specific desensitizing vaccine) hyposensitization.

Actinomycosis, rare in pelvic localization and a severe condition not well known to gynecologists, is an uncommon entity caused by anaerobic bacteria, Actinomycosis israelii. After trauma, surgery, or other infections that alter the host's mucosal barriers, these organisms advance to invade surrounding tissue and organs. The pelvic loculation of the disease generally presents as a pseudoneoplastic formation, so it is very difficult to make an accurate diagnosis initially. We experienced a pelvic and abdominal actinomycosis confirmed by pathology in a woman who had been wearing an IUD and complained fever, chill, headache for one month, and lower abdominal pain and palpable mass. This case illustrates the importance of considering the possibility of actinomycosis when we met a vague abdominal mass.
