A 59 years old woman, born in Fukuoka Prefecture, was admitted to our hospital in Aug, 1988 because of diarrhea, fever and skin eruption. Physical examination revealed systemic lymphadenopathy and hepatosplenomegaly. The white blood cell count was 11,200/microliters with 28% atypical lymphocytes with convoluted nuclei. Mild anemia, thrombocytopenia and hypercalcemia were also observed. Antibody against the adult T-cell leukemia (ATL) associated antigen in serum was positive. OKT 4/8 ratio was high. A diagnosis of ATL was made. Because of the complications of pneumonia and herpes simplex, systemic chemotherapy was not given, and interferon (IFN)-alpha-2b was intramuscularly injected daily from Oct, 1988, resulting in the disappearance of atypical lymphocytes and improvement of skin lesions. The effect of IFN therapy lasted for three months, followed by increase of atypical lymphocytes. Although the patient became refractory to systemic IFN therapy, local injection of IFN into a buccal tumor infiltrated with atypical lymphocytes resulted in its regression of size. In spite of continued administration of IFN, the patient died of pneumonia in Jan, 1989.

To date, the acquired immunodeficiency syndrome (AIDS) has been identified in over 50 children in the US, including those with associated hemophilia, high-risk environmental factors (Haitian background, parental intravenous drug abuse, or prostitution), and blood transfusions. The evaluation of an infant or young child in whom AIDS is suspected requires exclusion of congenital disorders of immune function. A specific test is not currently available, but inclusion criteria for childhood AIDS have been developed. The diseases accepted as indicative of underlying cellular immunodeficiency children are the same as those used in defining AIDS in adults, with the exclusion of congenital infections such as toxoplasmosis or herpes simplex virus infection in the 1st month of life or cytomegalovirus infection in the 1st 6 months of life. Specific conditions that must be excluded in children are primary immunodeficiency diseases (e.g., DiGeorge syndrome, Wiskott-Aldrich syndrome, ataxia-telangiectasia, neutrophil function abnormality) and secondary immuno-deficiency associated with immunosuppressive therapy, lymphoreticular malignancy, or starvation. Almost all young children with AIDS have hepatosplenomegaly, interstitial pneumonitis, and poor growth. The average age of 36 US child AIDS victims studied in detail was 5 months at presentation with findings suggestive of severe immunodeficiency. Mucocutaneous candidiasis was present in 75% of these 36 children, and Pneumocystis carinii and cytomegalovirus were each isolated from 30% of cases. Normal T4:T8 ratios occur in about 15% of pediatric AIDS cases. Laboratory evidence of polyclonal hypergammaglobulinemia generally supports the AIDS diagnosis. Recurrent infection and malnutrition are major problems in the clinical management of child AIDS patients.

Four Venezuelan patients with the autosomal recessive Chediak-Higashi syndrome (CHS) were studied. The results confirm the severe reduction in natural killer (NK) cell activity, as previously described and showed also a decline in the activity of cells involved in antibody-dependent cellular cytotoxicity (ADCC). No defect was found in the production of immunoglobulins and of specific antibodies to measles, varicella, herpes simplex, and cytomegalo viruses. Two of the patients had extremely high antibody titers to the Epstein-Barr virus (EBV) specific viral capsid antigen (VCA), to the restricted (R) component of the EBV-induced early antigen complex, and to the EBV-associated nuclear antigen (EBNA). These two patients had enlarged livers, spleens, and lymph nodes indicative of the lymphoproliferative phase. The other two patients were initially negative for all EBV-associated antibodies but seroconverted subsequently and, in the course of a year, also developed high antibody titers to VCA and R. In one of these patients the primary infection was accompanied by moderate signs of infectious mononucleosis (IM) followed after more than 6 months by persistent hepatosplenomegaly. The other patient also developed signs of a lymphoproliferative syndrome with hepatosplenomegaly and jaundice and died 8 months later. Such high anti-R titers are seen frequently in Burkitt's lymphoma, but rarely in other conditions. It is likely that the high antibody titers reflect an increased production of VCA and R due to defective NK and ADCC cell activities so that productively infected B lymphocytes are no longer eliminated before they have synthesized maximal amounts of antigens. The high anti-EBNA titers suggest normal T lymphocyte function. The possibility that the accelerated, lymphoma-like phase of the CHS involves EBV-transformed cells is discussed.

We studied two children who died of suspected familial erythrophagic lymphohistiocytosis. The first child, a 7-year-old boy, had fever, diffuse pulmonary infiltrates, bilateral choroidal effusions, diabetes insipidus, and marked meningitis with increased cerebrospinal fluid protein. Ocular histologic studies disclosed diffuse choroidal infiltrates consisting of atypical mononuclear cells with foamy cytoplasm. Similar histologic changes were seen in the lungs, liver, brain, and kidneys. The second child, the 5-year-old male cousin of Patient 1, had fever, hepatosplenomegaly, pulmonary infiltrates, and cerebrospinal fluid pleocytosis. Histologic changes were similar to those in the first case, but viral particles of the herpes simplex virus group were noted in brain tissue as well. The findings of virus particles in this histiocytic proliferative disease suggested a defect in the inflammatory response in these patients.

The clinicopathologic features of 23 patients with hematophagic histiocytosis (HH) are described. All of them exhibited increased histiocytes associated with hemophagocytosis in the marrow. The patients usually presented with fever, hepatosplenomegaly, lymphadenopathy, and cytopenia. The underlying illnesses were heterogeneous, including non-Hodgkin's lymphoma in 17, systemic lupus erythematosus in one, diabetes mellitus in one, acute myelomonocytic leukemia in one, myelodysplastic syndrome in one, and unknown cause in two. Among 17 non-Hodgkin's lymphoma, 14 were peripheral T-cell lymphoma, two were B-cell lymphoma, and one was an undefined phenotype. Among 14 patients with peripheral T-cell lymphoma, six of the patients had nasal T-cell lymphoma. Five of these 14 patients initially diagnosed as malignant histiocytosis turned out to be T-lineage lymphoma after immunophenotypic studies. Active infections, most of viral origin, were documented in eight patients, including Epstein-Barr virus in three, cytomegalovirus in three, herpes simplex virus in three, Pseudomonas aeruginosa in one, Bacteroides vulgatus in one, and mycoplasma in one. Some of them had mixed virus and bacteria infection. Sixteen (70%) of our patients died of their acute illness within 10 weeks of the diagnosis of HH. In the past, the clinical and histologic differentiation between hematophagic histiocytosis and true histiocytic neoplasm (histiocytic medullary reticulosis/malignant histiocytosis) has proved difficult, but now these can be distinguished with immunohistologic, immunogenetic, and cytogenetic studies, especially in the cases of peripheral T-cell lymphoma with hemophagocytic syndrome.

Indirect enzyme immunoassay, performed with Labsystems (Helsinki) kits, in 30 mothers and their newborns, revealed that 100% of parturient women present IgG antibody to hepatitis A (HAV), herpes simplex 1, and measles viruses, constantly transferring these antibodies to their newborns. 78.6% of the women had IgG to rubella (German measles) virus, passively transmitting them to their offsprings. Serological markers (HBsAg and anti-HBc) of hepatitis B virus infection were present in 42% of the investigated women, anti-HBc being also present in the serum of the newborns. Between the identified risk factors (in the past obstetrical history, current pregnancy, labor and early postnatal period) and the spectrum of IgG antibodies present in mothers no significant correlations were revealed. The same obvious lack of correlation between IgG antibodies and risk factors in the neonate (prematurity, low birth weight, malformations) was also found. However, the presence of IgG anti-measles (2 case), IgM anti-rubella (1 case) and IgM and HAV (4 cases) was associated, in the same order, with interstitial pneumonia, hepatosplenomegaly and death, icterus neonatorum, cardiovascular and neurologic malformations. Neither mothers nor their offsprings presented anti-HIV antibodies, suggesting that in the investigated patients no perinatal transmission had occurred.

Many infants with intrauterine growth retardation (IUGR) are screened for TORCH infections. The yield and costs of such a practice may not be justifiable. Medical charts of infants with IUGR who had a workup for toxoplasmosis, other (infections), rubella, cytomegalovirus (infection), and herpes (simplex) (titer) (TORCH) infections were reviewed for the presence of clinical findings, laboratory and head ultrasound abnormalities associated with intrauterine infections. Maternal charts and reports of placental pathology were reviewed for identifying maternal illnesses and placental causes associated with IUGR. Seventy-five out of 182 infants (41%) with IUGR had a workup for TORCH infection. Maternal conditions associated with IUGR included: pregnancy-induced hypertension (19%), tobacco use (43%), alcohol abuse (21%), illicit drug use (24%), chronic hypertension, diabetic vasculopathy or collagen vascular disease (12%), and multiple gestation (3%). Placental pathology was available in 53/75 cases. Thirty-six of fifty-three (67%) placentae had abnormalities associated with IUGR: placental infarcts (22 of 36), vasculitis/villitis (15 of 36), placenta previa (1 of 36), abruptio placenta (2 of 36), and velamentous insertion of umbilical cord (1 of 36). Clinical findings among infants included hepatosplenomegaly, cataract or rash (1 of 75), thrombocytopenia and/or neutropenia and/or direct hyperbilirubinemia (11 of 75). Seven out of 75 infants had dysmorphic features. None of the infants (0 of 75) had positive IgM titers for toxoplasma, rubella, cytomegalovirus (CMV), or herpes simplex virus (HSV). No infants (0 of 43) had elevated total IgM titers; one infant (1 of 57) had a positive urine culture for CMV. One infant had evidence of calcifications on head ultrasound and a second infant had hydrocephalus (2 of 43). The costs associated with workup for TORCH infections among 75 infants included: TORCH titers determination: $17,816, total IgM titers: $1318, urine culture for CMV: $5734, and head ultrasound: $28,165. The yield of workup for TORCH infection among infants with IUGR is poor and does not justify the incurred costs.

In 2 infants, a girl and a boy, congenital viral infection was diagnosed in the neonatal period. The prenatal examination (serologic investigation for Toxoplasma gondii, rubella virus, cytomegalovirus, herpes simplex virus and syphilis (TORCHES)) was negative. In both cases prenatal ultrasonography was abnormal and suggested intrauterine infection. The infants were born with typical symptoms of multisystem disease, known as symptomatic congenital cytomegalovirus infection (jaundice, petechiae, hepatosplenomegaly, intrauterine growth retardation, microcephaly and cerebral calcifications) and congenital rubella syndrome (intrauterine growth retardation, congenital heart disease, cataract, hepatosplenomegaly and cerebral calcifications), respectively. Both had severe cerebral damage. To diagnose severe congenital infection in the first trimester of pregnancy in presence of congenital anomalies in utero there are other possible methods than TORCHES investigation, such as polymerase chain reaction and virus culture in amniotic fluid or in foetal blood obtained by cord puncture.

A 24-year-old man was referred to our clinic in August 2003 with complaints of weakness, dizziness, and bilateral knee pain of 3 years' duration. Bilateral digital clubbing had been found on routine physical examination during his military service 4 years earlier. There were no cardiorespiratory or abdominal symptoms. There was no compromise in the activities of everyday life. The patient was not a chronic smoker. In the family history of the patient, his brother had been diagnosed with pachydermoperiostosis in another center 2 years earlier, but did not return to the hospital for a follow-up investigation of myelofibrosis. On physical examination, the patient showed marked drumstick clubbing of the hands (Fig. 1), and a pale general appearance. The causes of digital clubbing are shown in Table 1 (Fawcett RS, Linford S, Stulberg DL. Nail abnormalities: clues to systemic disease. Am Fam Physician 2004; 69: 1417-1424). Deep nasolabial folds were seen on the face. Skin hypertrophy, cutis verticis gyrata, and seborrhea on the face were also observed. The patient also complained of hyperhidrosis. Examination of the cardiovascular system was normal. There was bilateral swelling of the ankle and knee (Fig. 2). Hepatosplenomegaly was found on abdominal examination. Investigations showed hypochromic microcytic anemia [hemoglobin, 8.58 g/dL (normal, 12.2-18.1 g/dL); hematocrit, 28.1% (normal, 37.7-53.7%); white blood cell count, 3430/mm(3) (normal, 4600-10,200/mm(3)); neutrophils, 2470/mm(3) (normal, 2000-6900/mm(3)); lymphocytes, 820/mm(3) (normal, 600-3400/mm(3)); platelets, 162,000/mm(3) (normal, 142,000-424,000 mm(3)); mean corpuscular volume, 73.7 fL (normal, 80-97 fL)]. Anisocytosis, poikilocytosis, microcytosis, and hypochromia were observed on peripheral blood examination, and the erythrocyte sedimentation rate was 37 mm/h. The serum C-reactive protein level was 50.1 mg/L (normal, 0-5 mg/L). Biochemical parameters, including serum calcium, phosphate, alkaline phosphates and liver function tests, were found to be within the normal range. The causes of secondary hypertrophic osteoarthropathy associated with pulmonary, rheumatologic, endocrine, cardiac, and gastroenterologic disorders were excluded. Growth hormone level and thyroid function tests were normal. Antinuclear antibody, TORCH [Toxoplasma immunoglobulin M (IgM), rubella IgM, cytomegalovirus IgM, herpes simplex IgM] panel, and markers of hepatitis were negative. Serum Igs and rheumatoid factor were found to be within the normal range. There was subperiosteal new bone formation on bilateral knee X-ray (Fig. 3). Radiography of the chest, pulmonary function tests, arterial blood gas, and echocardiography were normal. Abdominal ultrasonography revealed hepatosplenomegaly. Amyloid deposition was not determined in rectal biopsy. Reticulin-type myelofibrosis was found on bone marrow biopsy (Figs 4 and 5). In the cytogenetic study, monosomy 22 was detected in four of 20 metaphase plates.

To investigate the clinical features of Kikuchi-Fujimoto disease (KFD) and the relationship between viral infection and this disease in children will be better as Kikuchi-Fujimoto disease (KFD) is a lymphadenopathy. The aim of study is to investigate the clinical features of KFD and the relationship. The age, gender, clinical features and aetiopathogenesis of 36 Chinese children with FKD were reviewed, and the viral antigens were detected. Mean age was 10.1 +/- 2.8 yr with a male to female ratio of 1.8:1. Fever and lymphadenopathy were the most common complaints, noted in 23 and all cases respectively. Skin rash and hepatosplenomegaly were also noted. Leukopenia, anemia, thrombocytopenia and raised ESR were noted in 21, 6, 4 and 31 cases respectively. Epstein-Barr virus (EBV) IgM and IgG was positive in 1 and 24 of 29 cases respectively. Antigens of EBV and herpes simplex virus 2 (HSV 2) were found in the biopsy tissue section from 2 and 1 case respectively. Autoantibodies were noted in 3 of 15 cases. Steroid hormones were administrated for 19 cases with good efficacy. These results imply that children with lymphadenopathy and/or fever may have KFD and thus excisional biopsy of lymph nodes should be performed earlier on. A hyperimmune reaction of immune cells to EBV and HSV2 may play a role in the pathology of KFD.
