One hundred and eleven children with Mycoplasma pneumonia infection were studied. Their mean age was 6.2 +/- 3.1 years. The two commonest symptoms were cough (98%) and fever (95%). Only 23% of children had cough of greater than one week's duration. Ninety one per cent had positive chest signs. Radiological abnormalities were seen in 95% of chest x-ray. Complications included dermatological (10%), pleural effusion (5%), neurological disorder (3%), septicaemia (1%), bronchiectasis (1%). Two children with Down's Syndrome died. A rare case of Mycoplasma bronchitis with Reye's Syndrome was observed.

The prevalence of nasal septal deformity and its relationship with the different types and difficulty of delivery were studied in a randomised group of newborns at the Maternity Hospital Kuala Lumpur between 1st November 1989 to 31st January 1990. Out of a total of 674 noses examined using the otoscope, 147 (21.8%) were found to have nasal septal deformity. There was no significant difference in the prevalence of nasal septal deformity in the different types of delivery. There was also no significant increase in the prevalence of nasal septal deformity with increasing degree of difficulty of the delivery. Therefore, we cannot then attribute parturition pressures or birth trauma as the etiology of these congenital nasal septal deformity. Nevertheless a policy of routine screening in view of early correction is advocated to decrease the morbidity associated with this deformity in newborns and children.

We report a patient with acute lymphoblastic leukemia who underwent treatment comprising chemotherapy, radiotherapy (cranial and testicular) and then a bone marrow transplant from an identical twin. He was cured of his leukemia and has been disease-free for nine years. With long term survival, there were problems, notably those of growth and endocrine insufficiency, which needed special considerations in management.

We report two brothers with anhidrotic ectodermal dysplasia (AED). AED is characterised by a triad of inability to sweat dental abnormalities and hypotrichosis. Although rare, it is important to diagnose this condition as it may lead to considerable morbidity and mortality if unrecognised. The typical features of this entity as described in the literature and as seen in our patients are emphasized as increased awareness can lead to early diagnosis and better prognosis.

A Malay baby with multiple cranial nerve involvement consistent with the Moebius sequence (syndrome) is reported. He also had many non-Central Nervous System (CNS) related defects which include limb reduction defects and the Poland sequence. A short annotation and the spectrum of this disorder are presented. In view of many reported related disorders, Moebius sequence may occur as a part of a broader pattern of malformation.

Molecular and non-molecular techniques have been utilized for the detection and characterisation of alpha- and beta-thalassaemia genes. Non-molecular techniques example, haematological indices and haemoglobin electrophoresis allow samples to be screened rapidly without the use of radionuclides but these techniques are unable to detect mutations at the gene level. Molecular analysis of alpha- and beta-globin genes either by Southern Blotting and radionuclides or DNA amplification using the polymerase chain reaction (PCR) allows detection of specific mutations and have enabled prenatal diagnosis of the thalassaemias.

The diagnosis of bacterial meningitis can be difficult nowadays when antibiotics are freely used in infants and children with fever due to infection, so that a positive smear or culture may be difficult to achieve. In areas where sophisticated methods of diagnosis may be hard to come by, the simple procedure of simultaneously estimating the blood and cerebrospinal fluid (CSF) glucose levels may be helpful in distinguishing bacterial meningitis from viral meningitis. 74 proven cases of bacterial meningitis and aseptic meningitis were investigated prior to treatment. There were 36 cases of bacterial meningitis and 38 cases of aseptic meningitis. The CSF glucose/plasma glucose ratio was calculated for each patient. The cases were divided into two groups; Group A with CSF glucose/plasma glucose ratio of (0.38-2.0) and Group B with CSF glucose/plasma glucose ratio of (0.1-0.35). In Group A, two out of 59 cases died while in Group B, nine out of 15 died (p < 0.01). 44 out of 59 in Group A recovered fully while only two out of 15 in Group B were cured (p < 0.01). It was also found that 54.2% in Group A were admitted in deep coma compared with 86.7% in Group B (p < 0.05) and 25.4% in Group A were admitted with seizures while 66.7% in Group B had convulsion (p < 0.01). Hence, a low CSF glucose/plasma glucose ratio was associated with a poor outcome. The mechanisms responsible for these findings are discussed especially with reference to the blood-brain barrier (BBB).(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty infants with obstructive jaundice were reviewed. Other than jaundice, hepatomegaly and splenomegaly were the other common presentations. The mean age of referral was 9.4 weeks. This was unsatisfactory as the prognosis depends on the age of corrective surgery. Majority of the non surgical cholestasis were due to idiopathic hepatitis. These patients did well as all of them were asymptomic and had no evidence of liver disease at 2 years of age.
