A 13 year review at the University Hospital, Kuala Lumpur reveals that chronic myeloid leukaemia (CML) constitutes 4.3% of all childhood leukaemia. Adult type of CML occurs in older children and is associated with marked splenomegaly, leukocytosis and thrombocytosis and the presence of Philadelphia chromosome. Although the initial response to busulphan was encouraging most of the patients succumbed; 2 patients underwent acute lymphoblastic transformation. Juvenile CML occurs in younger children and is associated with less marked splenomegaly, leukocytosis and thrombocytopenia and the presence of elevated fetal haemoglobin levels. The disease is characterised by an acute fulminating course. Despite improved survival in acute lymphoblastic leukaemia, the outlook for chronic myeloid leukaemia in childhood remains poor and treatment needs re-evaluation.

Hybrid acute leukaemia--a report of 3 cases

Ng SC, Wong TK, Lin HP

Ann Acad Med Singap, 1989 Nov;18(6):721-3.

PMID: 2624424

The simultaneous expression of both lymphoid and myeloid phenotypic features in acute leukaemia is rare. We report 3 cases of biphenotypic hybrid acute leukaemia seen in our institution. All 3 patients achieved remission with treatment for acute lymphoblastic leukaemia but two subsequently relapsed while on treatment. The hybrid acute leukaemias are important areas for further research both for delineation of basic biology and choice of optimal treatment.

Single incubation double esterase cytochemical reaction using a single coupling reagent

Ainoon O, Jabamoney AJ, Cheong SK

Malays J Pathol, 1991 Jun;13(1):47-9.

PMID: 1724544

Most methods used in double esterase cytochemistry for the diagnosis and classification of acute myeloid leukaemias require double incubation and staining, using separate coupling reagents. We evaluated a method by Swirsky on our normal and abnormal blood and bone marrow smears where only a single incubation and the use of a single coupling reagent is required. Its short incubation period and its strong positive reaction for butyrate esterase in demonstrating cells of monocytic lineage gives it an advantage over the conventional double incubation technique.

Fulltext Analysis of ras gene mutations in acute myeloid leukemia by the polymerase chain reaction and oligonucleotide probes

Chin YM, Bosco JJ, Koh CL

Singapore Med J, 1992 Feb;33(1):48-50.

PMID: 1598607

In vitro deoxyribonucleic acid (DNA) amplification by the polymerase chain reaction (PCR) followed by hybridization with oligonucleotide probes were used to study ras gene mutations in acute myeloid leukemia (AML). The DNA of 30 AML patients at presentation of the disease at the University of Malaya Hospital, Kuala Lumpur were screened for ras gene mutations in codons 12, 13 and 61 of the N-ras, K-ras and H-ras genes. Four patients (13.3%) had ras gene mutations. They were all below their early thirties in age. Of the four patients with ras gene mutations, three were M3 and one was M4 according to the French American British (FAB) classification of AML.

Biphenotypic hybrid acute leukaemia detected by two colour flow cytometry

Gudum HR, Chin YM, Menaka N, Jeyaranee S, Lin HP, Tay A

Malays J Pathol, 1992 Jun;14(1):25-8.

PMID: 1469914

Immunophenotypic studies using immunofluorescent flow cytometry were performed on the blast cells of 36 patients with acute leukaemia using a panel of eight monoclonal antibodies. Six patients had blasts which co-expressed markers for lymphoid and myeloid differentiation, and which were therefore defined as biphenotypic hybrid acute leukaemia. Of the six, three patients were in the paediatric age group (below 12 years old) while the other three were more than 12 years old. Peripheral blood counts were variable; however, bone marrow infiltration was extensive (blasts > or = 75% in all). At the time of study, remission was achieved in only two patients. The authors' data show that biphenotypic hybrid acute leukaemia is not rare in Malaysia. This represents a subgroup of acute leukaemia identifiable by immunophenotyping but not by the French-American-British classification based on morphological and basic cytochemical studies alone. The recognition of this subgroup is important for both practical and theoretical reasons. There are implications for treatment of the individual patient because treatment directed at a single lineage may not be effective. The two colour flow cytometry proved to be a useful tool for diagnosis and classification of acute leukaemia.

PMID: 8466468

Neutropenic enterocolitis is a complication of patients receiving chemotherapy for malignant disease. It has a characteristic presentation and may lead to gut perforation with consequent high mortality. It is best treated by early surgical intervention. Considerable mortality is inevitable in these gravely ill patients.

Fulltext Varicella in children with haematological malignancy--outcome of treatment and prevention

Ho CM, Khuzaiah R, Yasmin AM

Med J Malaysia, 1994 Mar;49(1):29-35.

PMID: 8057987

Primary varicella-zoster virus infection in children with haematological malignancy is a life threatening disease. In one year, there were 10 cases of varicella and 2 cases of zoster among these children as well as 5 mothers who were accompanying their children who developed varicella in the oncology ward. Two children died of fulminating disease despite aggressive antiviral and supportive treatment. Acyclovir can be used in treatment and prophylaxis in exposed susceptible children. Varicella -zoster immune globulin is not available in this country. Vaccination with live virus has been shown to be protective in immunocompromised children and needs consideration.

Retinal findings in adult leukaemia: correlation with leukocytosis

Jackson N, Reddy SC, Hishamuddin M, Low HC

Clin Lab Haematol, 1996 Jun;18(2):105-9.

PMID: 8866143

The associations between retinal findings and haematological parameters in acute leukaemia are controversial. Sixty-three newly-diagnosed acute leukaemia patients, aged 12-77 years, were studied prospectively for the presence of intra-retinal haemorrhages (IRH), white-centred haemorrhages (WCH), cotton wool spots (CWS) and macular haemorrhages (MH), Thirty-three patients (52.4%) showed at least one retinal abnormality. The prevalence of individual findings was: IRH (30 cases), WCH (20 cases), CWS (5 cases), MH (11 cases). In contrast to previous studies, there was no association between any of these retinal findings and the haemoglobin level or the platelet count. There was a higher median WBC in patients with IRH (68 x 10(9)/l) than in those without IRH (15.4 x 10(9)/l), P = 0.037. When the acute myeloblastic leukaemia cases were considered separately, an association was also found between higher WBC and the presence of WCH and CWS. There was no association between retinal findings and FAB type in the AML cases. We conclude that a high WBC may be at least as important as anaemia and thrombocytopenia in the pathogenesis of the retinopathy of acute leukaemia.

PMID: 8942241

A 45-year-old Malay lady developed brisk vesicular, plaque-like reaction to a Mantoux test concomitant with a diagnosis of acute myeloid leukaemia (AML). The lesion resolved one month after chemotherapy. Similar lesions developed later after she was bitten by mosquitoes on the forearms. She also had the lesions over her cheek. A skin biopsy showed infiltration of the dermis with neutrophils and some monocytoid cells. The lesion resolved one week after prednisolone therapy.

Macular haemorrhage in adult acute leukaemia patients at presentation and the risk of subsequent intracranial haemorrhage

Jackson N, Reddy SC, Harun MH, Quah SH, Low HC

Br J Haematol, 1997 Jul;98(1):204-9.

PMID: 9233585

Retinal changes are common in adult acute leukaemia patients at presentation, but whether they correlate with the risk of subsequent intracranial haemorrhage is unknown. A 4-year study has been carried out in 82 newly-diagnosed acute leukaemia patients, aged 12-77 years, who were studied prospectively for the presence of intra-retinal haemorrhages (IRH), white-centred haemorrhages (WCH), cotton-wool spots (CWS) and macular haemorrhages (MH). Groups with and without these features were compared for their risk of intra-cranial haemorrhage (ICH) within the first 30 d following diagnosis. There was no association between the incidence of ICH and the presence of IRH, WCH or CWS. However, 6/13 of those with MH developed ICH, compared to 6/69 of those without MH (relative risk 5.0, CI 95% [2.03-12.33], P=0.003). The only other identifiable risk factor for ICH was the M3 subtype of AML, but if the four cases of M3-AML were discounted from analysis, MH remained a highly significant risk factor for ICH. Patients with MH should be monitored intensively for the development of ICH, and receive priority in the allocation of platelets where these are in short supply.

A prospective study of ocular manifestations in childhood acute leukaemia

Reddy SC, Menon BS

Acta Ophthalmol Scand, 1998 Dec;76(6):700-3.

PMID: 9881556

PURPOSE: To determine the prevalence of ocular manifestations in childhood acute leukaemia at the time of presentation.

METHODS: Eighty-two children with acute leukaemia were examined for ocular lesions within two days of diagnosis before starting chemotherapy. The detailed ocular examination of both eyes was carried out by the ophthalmologist irrespective of the presence or absence of eye symptoms in all cases.

RESULTS: Only 3 out of 82 children presented with eye symptoms (3.6%). However, ocular changes were found in 14 children (17%); ten with lymphoblastic and four with myeloid leukaemia. The ocular lesions observed were proptosis, intraretinal haemorrhages, white centered haemorrhages, cotton wool spots, macular haemorrhage, subhyaloid haemorrhage, vitreous haemorrhage, papilloedema, cortical blindness, sixth nerve palsy, and exudative retinal detachment with choroidal infiltration.

CONCLUSION: In view of the high prevalence of asymptomatic ocular lesions in childhood acute leukaemia, routine ophthalmic examination should be included as a part of evaluation at the time of diagnosis.

Immunophenotyping pediatric leukemias in Kelantan, Malaysia

Menon BS, Dasgupta A, Jackson N

Pediatr Hematol Oncol, 1998 Mar-Apr;15(2):175-8.

PMID: 9592844

This study reviewed the immunophenotyping results of children with acute leukemia in Kelantan, Malaysia. In the 3.5-year period (January 1994 to June 1997), 45 cases were identified. All children were under the age of 12 years and the predominant ethnic group was Malay. Thirty-six cases (80%) were acute lymphoblastic leukemia (ALL) and 9 cases (20%) were acute myeloblastic leukemia (AML). Of the ALL cases, 3% were of B-cell and 22% of T-cell origin, and 96% of the B-lineage ALL were CD10 positive. All the AML cases expressed CD33 and 78% were positive for CD13. The incidence of mixed-lineage leukemias was 13.8% for My+ ALL and 11.1% for Ly+ AML.

Fusarium species is an emerging genus of fungal pathogens which until recently were rare causes of human disease apart from localized infection of the skin and nails. Two cases of fungaemia due to Fusarium sp. in children are described. The first child, an 8-year old girl with acute myeloid leukaemia developed character-sitic pyoderma gangrenosum-like skin lesions before succumbing to disseminated Fusarium infection and acute respiratory distress syndrome. The second child, a 5-month old boy, developed pneumonia associated with a transient erythematous skin rash while on chemother-apy for congenital leukaemia. Both patients had Fusarium isolated from blood. The second child improved after six weeks of treatment with ampho-tericin B and granulocyte-macrophage colony stimulat-ing factor but ultimately she died of the disease follow-ing discharge. Fusarium spp should be recognised as an opportunistic pathogen in immunocompromised patients. Current literature suggests that liposomal amphotericin B in conjunction with leukocyte growth factors are the treatment of choice in this potentially fatal infection.
