The function of blood neutrophil granulocytes was studied in vitro in 17 patients with preleukaemia. 3 patients had a cellular defect of chemotaxis. 2 of them had monosomy-7 in bone marrow karyotype, in 1 associated with the deletion of the long arm of a chromosome 20. The third patient had trisomy-8. In the patient with trisomy-8, the high percentage of band neutrophils was possibly associated with the chemotactic defect. In another patient with trisomy-8 chemotaxis was normal. There was a statisically significant tendency to reduced phagocytosis and impaired ability to kill Staphylococcus aureus. 1 patient with a chemotactic defect and monosomy-7 suffered from repeated infections. The other 2 patients with defective chemotaxis had several febrile episodes most probably of infectious origin, and 1 of them died in sepsis. All of these 3 patients had cutaneous abscesses. It is concluded that defects in neutrophil granulocyte function are not uncommon in preleukaemia and may result in reduced resistance to infection.

Although survival in infants with congenital intestinal obstruction has improved, duodenal obstruction continues to present unique challenges. One hundred thirty-eight newborns and infants (aged 0 to 30 days) were treated for congenital duodenal obstruction. Sixty-five were boys and 73 were girls. Sixty-one (45%) were premature. Forty-six had an intrinsic defect (atresia, web, stenosis, or duplication), 64 had an extrinsic defect (annular pancreas or malrotation with congenital bands), while 28 had various combinations of these. Presenting signs included vomiting (90%, bilious in 66%), abdominal distention (25%), dehydration (24%), and weight loss (17%). Although plain film abdominal x-ray was diagnostic in 58%, upper and/or lower gastrointestinal contrast studies were obtained in 71% of infants to confirm diagnosis. Thirty-eight percent of patients had associated anomalies, including Down's syndrome (11%), cardiac defects, other atresia, other trisomy syndrome, imperforate anus, and central nervous system anomalies. Fourteen patients (10%) had 3 or more other anomalies, many of which required additional surgical therapy. The operative repair of the various defects included Ladd's procedure for malrotation (31%), duodenoduodenostomy (14%), duodenojejunostomy (22%), gastrojejunostomy or gastroduodenostomy (4%), excision of the web and duodenoplasty (3%), or combination of the above (22%). Gastrostomy was placed in 61%. One hundred twenty-eight patients survived (93%). The causes of death were combinations of sepsis, pneumonia, brain hemorrhage, short bowel, and cardiac anomaly. Eight of 10 (80%) who died had other serious anomalies. Twenty patients (14%) required reoperation 5 days to 4 years postoperatively for obstructing lesions (5), wound dehiscence (3), anastomotic leak or dysfunction (6), other atresias (2), choledochal cyst (1), pyloric stenosis (1), and gastroesophageal reflux (2).(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 30-month-old female with intrauterine growth retardation, postnatal failure to thrive, pancytopoenia and myelodysplasia with monosomy 7 in the marrow. The child succumbed to overwhelming sepsis, following a bone marrow transplant to facilitate chemotherapy for metastatic hepatoblastoma--a tumour that has not been previously reported in myelodysplasia syndromes. Cytogenetic, molecular and microarray analysis of peripheral blood, skin fibroblasts and bone marrow revealed unusual results, suggestive of somatic chromosome instability. A normal peripheral blood karyotype was documented in infancy. Monosomy 7 was found in the bone marrow. Molecular (microsatellite marker) results for a later peripheral blood specimen were suggestive of partial maternal isodisomy 7q, and this was supported by microarray data on single-nucleotide polymorphisms. Microarray data on gene copy number, collected for the same blood specimen, indicated cryptic mosaicism for the monosomy 7 cell line, with the monosomic line lacking the paternal copy. In fibroblasts, cytogenetic data showed mosaic partial trisomy for distal 7p.

Streptococcus bovis very occasionally causes rarely sepsis, endocarditis, and meningitis in newborns and the elderly. We report the case of infant meningitis caused by S. bovis despite normal cerebrospinal fluid (CSF) findings at the first CSF examination. A 77-day-old boy with 21-trisomy and patent foramen ovale and seen for a high fever underwent blood examination and lumbar puncture due to toxic appearance despite a lack of meningeal signs, and was admitted. His CSF findings were normal and he was given intravenous ceftriaxone against potential bacteremia. He had systemic seizures with continuous fever for 2 days after admission and a second CSF examination. Gram-positive coccus grew from his CSF at the first examination, and CSF cells from the second lumbar puncture increased to 4060/tL (86% neutrophils), so vancomycin was added against potential enterococcal meningitis. S. bovis was finally grown from the first CSF, ceftriaxone discontinued, and intravenous ampicillin added. He recovered after 20 days of antibiotic administration. S. bovis becomes a potential pathogen for meningitis in infants, and must be considered as a cause of meningitis despite its very rarity. CSF findings at the first lumbar puncture may be normal for meningitis in newborns and infants at the first CSF examination, so we must be very careful in the diagnosis of bacterial meningitis even with normal CSF findings, and considered antibiotic treatment against potential bacterial meningitis.

Cytogenetic classification of acute lymphoblastic leukemia (ALL) is primarily based on numerical and structural chromosomal abnormalities. In T-cell ALL (T-ALL), chromosomal rearrangements are identified in up to 70% of the patients while the remaining patients show a normal karyotype. In the present study, a 16-year-old male was diagnosed with T-precursor cell ALL and a normal karyotype after standard GTG-banding, was studied retrospectively (>10 years after diagnosis) in frame of a research project by molecular approaches. In addition to molecular cytogenetics, multiplex ligation-dependent probe amplification (MLPA) and high resolution array-comparative genomic hybridization (aCGH) were also applied. Thus, the following yet unrecognized balanced chromosomal aberrations were detected: der(3)t(3;5)(p23;q31.1), der(5)t(3;5)(p23;q35.3), der(5)t(5;10)(q31.1;p12.3) and der(10)t(5;10)(q35.3;p12.3). The oncogene MLLT10 was involved in this rearrangement as was the IL3 gene; in addition, trisomy 4 was present. All of these clonal aberrations were found in 40% of the cells. Even if this complex karyotype would have been identified at the time of diagnosis, most likely no other protocol of anticancer therapy (ALL-BFM 95) would have been applied. Three months after the end of a successful 2-year treatment, the patient suffered from isolated bone marrow relapse and died of sepsis during ALL-REZ-BFM protocol treatment.

There is a lack of standardized nomenclature for renal cysts lined by multiple cell layers or with short papillary projections but without nests of epithelial cells within the stroma. We retrieved 29 cases (15 nephrectomies, 14 partial nephrectomies) from the surgical pathology files of Johns Hopkins Hospital from 1993 to 2014 and performed immunohistochemistry for CK7, alpha-methylacyl-CoA racemase (AMACR), CAIX, and CD10 and fluorescence in situ hybridization for trisomy 7 and 17 and 3p deletion. The mean age at excision was 58 years (range, 29 to 80 y) with 16 men and 13 women. Mean size was 2.9 cm (range, 0.3 to 10 cm). The cysts were grouped by their morphology into (1) clear cell, (2) eosinophilic stratified, and (3) eosinophilic papillary. By immunohistochemistry, 7/9 (78%) of the clear cell cases were diffusely positive for both CK7 and CAIX resembling the pattern seen in clear cell papillary renal cell carcinoma. The majority of eosinophilic stratified (4/6; 67%) and eosinophilic papillary (12/14; 86%) cases were positive for CK7 and had variable staining for AMACR, CD10, or CAIX, suggesting a differentiation more aligned with papillary renal cell carcinoma. The most common molecular alterations detected were trisomy 17 (n=6) and trisomy 7 (n=4). One case showed deletion of chromosome 3p. Clinical follow-up information was available in 23 patients; 20 were alive with no evidence of disease after a median follow-up of 20 months (range, 3 to 120 mo), 1 patient was dead due to metastatic lung cancer, 1 of sepsis, and 1 of unknown reason. Atypical renal cysts present as complex radiologic lesions, as secondary lesions in patients with a renal mass, or in a background of chronic renal disease. These atypical cysts appear heterogenous, and some follow in their morphology and immunoprofile with well-established renal tumors. The presence of 3p deletion and trisomy 7/17 suggests that in some cases they may be precursors of renal cell carcinoma. Longer follow-up with more cases is needed, but on the basis of our data, these lesions should not be diagnosed as carcinoma.

Chronic lymphocytic leukemia (CLL) typically pursues a prolonged course. Its transformation into a more aggressive lymphoma occurs in 2-8% of all patients. Most commonly, diffuse large B-cell lymphoma develops. Transformation into a classical Hodgkin's lymphoma (cHL) occurs in <1%. Plasmablastic transformation has been only rarely reported. Cases of synchronous divergent transformation of CLL into a composite lymphoma are exceedingly rare. We describe the unique occurrence of the transformation of a long-standing CLL into a synchronous clonally related cHL as well as plasmablastic lymphoma (PBL) in an 85-year-old female patient. After 10 years of asymptomatic CLL, our patient was treated with a rituximab-chlorambucil scheme in combination with pegfilgrastim for recurrent infections and the development of B symptoms. Five cycles (of six planned) were administrated with no adverse effects. After the fifth cycle, lymphadenopathy with pronounced B symptoms appeared. Histology showed the presence of cHL in the lymph node, while the bone marrow was infiltrated by PBL. Our patient died in sepsis not receiving further specific oncologic treatment due to her poor general condition. Additional cytogenetic and molecular studies showed that this was a case of mutated CLL with trisomies of chromosomes 12, 3, and 18 (a rare specific +12 plus other-non+19 CLL subgroup). The presence of trisomy 12 has also been proved in plasmablasts and in cHL cells.
