Marshall's syndrome or periodic fever syndrome was first described in 1987 in the USA based on observations of 12 children under the age of five with periodic fever (> 38 degrees C) and accompanying aphtous stomatitis, pharyngitis, and cervical adenopathy (PFAPA). In 1998, a national retrospective study was carried out in France by the pediatric infectious pathology group, and a semeiological analysis was made of 22 cases. The main characteristics of Marshall's syndrome found in this patient population were in agreement with those reported in the literature. The onset of symptoms occurred between the age of 3 months and 12 years, with a mean age of 5 years; no geographical or ethnic predisposing factors were noted. The diagnosis of symptoms was subsequently established at an age ranging from 5 months to 16 years, with a mean age of 6.5 years. It was determined that following an initial phase of generalized clinical manifestations (asthenia, cranial neuritis, dysphagia, anorexia), the symptoms become stereotyped, with the sudden appearance of high fever (> 40 degrees C), shivering, aphtous stomatitis, pharyngitis, and cervical adenopathy. Other symptoms such as cranial neuritis, arthralgia, and abdominal pain may also be present (50% of cases in the present study), but due to their variability of appearance they are of lesser diagnostic value. The main characteristic of Marshall's syndrome is its periodic aspect; with fever occurring every 6 to 9 weeks, with a mean interval of 66 days before recurrence of fever compared to the shorter interval of 21 to 28 days reported in the literature. After excluding the presence of an infection, the differential diagnosis includes the following: familial Mediterranean fever, hyper IgD syndrome, and feverish neutropenia. During the periods of fever, an inflammatory syndrome with hyperleucocytosis and a marked increase in C-reactive protein (CRP) levels and sedimentation rate is observed. The most effective treatment seems to be the early administration of corticoids during the initial phase, prior to the appearance of more specific symptoms. The prognosis is excellent, with a progressive decrease in the incidence of periodic fever and an absence of complications. However, the etiology of Marshall's syndrome has not yet been determined.

The effects of virus dose on host response were evaluated for the PPR strain of feline immunodeficiency virus (FIV-PPR). Specific pathogen-free cats were inoculated intravenously with 50, 250 or 1250 TCID(50) of FIV-PPR. Two weeks after inoculation, virus was detected in 10(6) peripheral blood mononuclear cells (PBMCs) of all infected animals, and the CD4(+):CD8(+) T lymphocyte ratios fell from greater than 2 to approximately 1 in all infected animals within the first 8 weeks after infection. Provirus detected in all groups using PCR and 10(3) PBMC was biphasic. Nine of 15 animals were positive between weeks 2 and 4 p.i. and 14 of 15 were positive by week 8 p.i. Transient lymphadenopathy was detected in most cats receiving 1250 TCID(50) and the 250 TCID(50) of virus, whereas no lymphadenopathy was detected in the 50 TCID(50) group or the five uninfected cats. Animals that had received the largest dose seroconverted earliest (on average at week 4.0) and those receiving the least seroconverted last (on average at week 5.6). Neither neutropenia nor lymphopenia were detected. FIV-specific CTL responses of memory effector cells could be detected in animals receiving all three doses but was highly variable among individual animals. Neurological manifestations determined after 15 weeks p.i. were observed in most infected cats, including two of the three that had received 50 TCID(50) of virus. However, the observed neurologic abnormalities were markedly less severe in the animals receiving the least amount of virus. Therefore, lymphadenopathy and neurologic signs of illness were less severe and seroconversion was slower in the animals that received the lowest dose compared with those receiving the 250 and 1250 TCID(50) doses of the FIV-PPR strain.

Kikuchi's lymphadenitis is a histiocytic necrotizing lymphadenitis without granulocytic infiltration, with fever and generally with a benign course, despite its pathologic resemblance to malignant lymphoma. The illness usually begins with localized cervical adenopathy in young adult females, predominantly before the fourth decade of life. Clinically, several agents could be the cause of such an illness--toxoplasmosis, herpes group viral infection, cat scratch disease, lymphoma, SLE and other infectious agents. The diagnosis is made by using a histological technique. The lymph node biopsy reveals fibrinoid necrosis, loss of lymph node structure with many histiocytes and an absence of granulomatous reaction. The immunohistochemical analysis shows that the main affected cellular components are the T cells. Laboratory exams show an erythrocyte sedimentation increase, neutropenia, leukopenia and lymphocytosis. We describe two cases that were followed since 1994 and 1996, respectively. Both were females under 25 years old, who developed a febrile disease with lymphadenopathy. Lymph node biopsies showed necrotizing lymphadenitis without granulocytic infiltrations. The patients had no evidence of other systemic diseases. Our objectives are to present a rare cause of febrile disease with enlargement of cervical lymph nodes, to review Kikuchi's disease, and to alert the medical community to this rare cause of fever and lymphadenopathy.

Kikuchi's disease is usually a self limiting illness characterised by pyrexia, neutropenia, and cervical lymphadenopathy particularly in young women of Asian descent. This often leads to an initial misdiagnosis of lymphoma. A case of a young Asian woman who presented with pyrexia of unknown origin is described.

The term periodic fever syndrome has been used in a restricted sense to denote two diseases in which episodic fevers occur with a regular periodicity: cyclic neutropenia and the periodic fever, aphthous stomatitis, pharyngitis, and adenopathy (PFAPA) syndrome. Other authors have used the term in a more general sense to encompass a larger group of disorders characterized by recurrent episodes of fever that do not necessarily follow a strictly periodic pattern. These include familial Mediterranean fever, the autosomal dominant familial fevers (also known as Hibernian fever), and the hyperimmunoglobulin D syndrome. This article follows the latter usage, and reviews recent advances in our understanding of the genetics and molecular pathology of this group of diseases, as well as their clinical characterization and treatment.

Lymphoproliferative disorders of large granular lymphocytes (LGL) can arise from either CD3+ T cells or CD3- natural killer cells. Polyclonal proliferation of LG lymphocytes is called LGL lymphocytosis, monoclonal proliferation of LG lymphocytes is LGL leukaemia. Prominent clinical manifestations of LGL lymphocytosis and leukaemia are bacterial infections, splenomegaly, and may be connected with rheumatic or autoimmune disorders. Hematologic findings reveal particularly lymphocytosis, and severe neutropenia. The beta chain gene of T cell receptor rearrangement analysis is necessary for distinguishing of T LGL lymphocytosis from T LGL leukaemia. The authors report a case of young woman with T cells LGL lymphroproliferative disorder, bacterial infection, reactive lymphadenopathy, and spontaneous regression of the lymphocytosis within 6 months.

Paclitaxel is an active agent for adenocarcinomas and squamous cell carcinomas of the esophagus and is a radiation sensitizer. We sought to investigate the toxicity and complete response rate of paclitaxel, cisplatin, and concurrent radiation for esophageal cancer. Forty-one patients with esophageal cancer were studied, 29 with adenocarcinomas and 12 with squamous cell cancers. Twelve patients had tumor extension into the proximal stomach and/or abdominal adenopathy. Patients received paclitaxel 60 mg/m2 by 3-hour intravenous (i.v.) infusion, and cisplatin 25 mg/m2 weekly on days 1, 8, 15, and 22. Radiation was administered concurrently to a total dose of 39.60 Gy, in 1.80 Gy fractions, for 22 treatments. Patients with medical or surgical contraindications to esophagectomy received 2 additional weeks of paclitaxel with a radiation boost to 50.4 Gy. Neutropenia was the most common grade 3/4 toxicity occurring in 10 patients (24%). Only 2 patients (5%) had grade 4 esophagitis requiring parenteral nutrition. Twelve patients (29%) obtained a complete response. The 2-year progression-free and overall survival rates were 40% and 42%, respectively. Esophagitis was less severe than expected and prophylactic enteral feeding tubes were not necessary. Additional effective systemic treatments are needed to reduce the development of distant metastases.

Kikuchi-Fujimoto's disease (KFD), Histiocytic Necrotizing lymphadenitis, is a rare self-limiting condition characterized by lymphadenopathy, fever and neutropenia. The aetiology of KFD is controversial, and its diagnosis is confirmed histologically. Although KFD has rarely been reported associated to Systemic lupus erythemotosus (SLE) should be ruled out given its different prognosis and management. We present the clinical, histological and evolution the two cases of patients with Kikuchi's disease; one case had evolution classic and the other case were associated with SLE.

To investigate whether cytokine responses may have a bearing on the symptoms and outcome of parvovirus B19 infection, circulating cytokines were measured during acute infection (n=51), follow-up of acute infection (n=39) and in normal healthy controls (n=50). At acute B19 virus infection (serum anti-B19 IgM-positive), patients ranged in age from 4 to 54 years, with a mean age of 28.2 years. The male:female ratio was 1:4.1 and symptoms were rash (n=15), arthralgia (n=31), fatigue (n=8), lymphadenopathy (n=4), foetal hydrops (n=3), transient aplastic crisis (n=2), neutropenia (n=2), myelodysplasia (n=1), thrombocytopenia (n=1) and pancytopenia (n=1). Of these patients, 39 were contacted after a follow-up period of 2-37 months (mean of 22.5 months). In comparison with normal controls, detectable IL-6 was associated with acute B19 virus infection (26%; P=0.0003), but not with follow-up (6%; P=0.16). Detection of interferon (IFN)-gamma was associated with acute B19 virus infection (67%; P<0.0001) and follow-up (67%; P<0.0001). Detection of tumour necrosis factor (TNF)-alpha was associated with acute B19 virus infection (49%; P<0.0001) and follow-up (56%; P<0.0001). IL-1beta was detected in acute infection (20%), but not at follow-up. At acute B19 virus infection, detection of serum/plasma IL-6 was associated with rheumatoid factor (P=0.038) and IFN-gamma (> or =7 pg/ml) was associated with fatigue in those patients of > or =15 years of age (P=0.022). At follow-up, fatigue was associated with IFN-gamma (> or =7 pg/ml) and/or TNF-alpha (> or =40 pg/ml) (P=0.0275). Prolonged upregulation of serum IFN-gamma and TNF-alpha appears to represent a consistent host response to symptomatic B19 virus infection.

We describe a 69-year-old Japanese male with acute leukemia with a CD7+ and CD56+ immunophenotype presenting with multiple lymphadenopathy. He was treated with idarubicin and cytosine arabinoside. Although the leukemia showed partial response, the patient did not achieve complete remission. He died of sepsis due to severe neutropenia after the third course of chemotherapy. His autopsy revealed blast infiltration in the lymph nodes, liver, spleen and vertebral bone marrow. Recently, CD7+ and CD56+ myeloid/natural killer precursor acute leukemia has been associated with a poor prognosis. Our case illustrates that myeloid/natural killer cell precursor acute leukemia shows some response to intensive chemotherapy for acute myeloid leukemia, but such therapy is insufficient to effect a cure. To overcome the resistance of this disease to chemotherapy, further studies should explore other treatment strategies.
