    Retinal changes are common in adult acute leukemia patients at presentation, but their prognostic significance is controversial. A 5-year study has been carried out with newly diagnosed acute leukemia patients aged 12-77 years. Seventy-seven cases (49 AML, 28 ALL) were studied prospectively for the presence of intraretinal hemorrhages (IRH), white-centered hemorrhages, cotton-wool spots, and macular hemorrhages. They were treated according to standard chemotherapy protocols, and then achievement of complete remission (CR) and the duration of overall survival (OS) were compared between the groups with and without these different retinal features. No association was found between the presence of any retinal abnormality and CR induction rate, although there was a trend to a lower CR rate among patients with IRH. The median OS of those with IRH was 72 days, compared with 345 days among those without IRH (p=0.002). A WBC at presentation greater than 50x10(9)/l and age greater than 40 years were also associated with shorter OS (p<0.0001 and p=0.0045, respectively). However, after regression analysis, IRH remained statistically significant as a poor prognostic indicator (p=0.01). We conclude that the presence of IRH is an indicator of poor prognosis in acute leukemia.

    OBJECTIVE: To evaluate the usefulness of antifilarial IgG4 antibody assay in detecting B. malayi infection in a filaria endemic area in Malaysia.

    METHODS: A sandwich ELISA using B. malayi soluble antigen was employed to detect antifilarial IgG4 antibodies in serum samples of 330 individuals who comprised 88 healthy individuals from nonendemic areas, 15 B. malayi microfilaraemic cases, 22 individuals with soil-transmitted helminthiases, 9 elephantiasis cases and 196 residents from a B. malayi-endemic area. An O.D. value of > 0.420 at serum dilution of 1:400 was used as the cut-off point. This cut-off point was obtained by taking the mean optical density (0.252 + 4 S.E.) of 36 negative sera which had O.D. values greater than 0.1 at serum dilution of 1:400.

    RESULTS: All 15 microfilaraemic persons were positive for antifilarial IgG4 antibody. Non-endemic normals, soil-transmitted helminth infected persons and chronic elephantiasis cases were negative for antifilarial IgG4 antibody. Of the 196 individuals from the filaria endemic area, 37 (18.8%) demonstrated presence of antifilarial IgG4 antibodies; and only eight individuals (4.1%) were positive for microfilariae. All eight microfilaraemic individuals were also positive for antifilarial IgG4 antibodies.

    CONCLUSION: Antifilarial IgG4-ELISA could detect 4.6 times more positive cases than the microfilaria detection method. With appropriate cut-off values that eliminate cross-reactivities, this serological tool is very useful for Brugia malayi prevalence surveys and diagnosis.

    Congenital laryngotracheo-oesophageal cleft is a rare anomaly which presents a challenge to the anaesthetists because of the potential problems of establishing and maintaining an airway. We report the anaesthetic management of a one-month old baby with complete or type IV laryngotracheo-oesophageal presenting for the repair of the defect. The management of the precarious airway is presented and the various techniques of managing the airway are reviewed.

    Pharyngeal involvement in tuberculosis is rare and is usually secondary to pulmonary tuberculosis. We report a very rare case of chronic granulomatous pharyngitis, which later turned out to be due to primary tuberculosis of the pharynx. The clinical presentation, diagnosis, treatment and complications of this rare clinical entity are presented.

    The constancy of strain genotypes of multiple isolates of Burkholderia pseudomallei from 13 patients with melioidosis was examined by BamHI ribotyping and pulsed-field gel electrophoresis (PFGE) of XbaI digests of DNA. Seven of 8 patients with single episodes of melioidosis each yielded genetically identical isolates and only one of five patients with recurrent episodes was infected with a new strain clearly distinct from the original primary strain. Variation was observed in PFGE patterns of primary and relapse isolates of another patient but this was insufficient to define genetically distinct strains. We conclude that most patients with single or multiple episodes of melioidosis retain a single strain.

    Dental pulp is prone to dystrophic mineralization; this mineralization can be so extensive that the entire root canal system is obliterated. As a result, root canal treatment can become a difficult if not impossible task. This article presents the endodontic management of a tooth with an obliterated pulp chamber and associated with a discharging sinus in a teenage patient. The role of a calcium hydroxide lining to induce mineralization and cause the obliteration of the pulpal space is also discussed.

    Retropharyngeal abscess (RPA) is relatively rare today. A study of 17 cases of RPA treated at our hospital in the past 10 years showed a shift in the disease from children below 6 years of age (41%) to older children and adults (58%). Upper respiratory tract infection (URTI) was found to be the commonest (52%) aetiological predisposing factor in all age groups. Other aetiological factors were septicaemia (11%) in children below the age of 6 years and trauma due to foreign body (35%) in the older children and adult age groups. Klebsiella, Staphylococcus and Streptococcus were the commonest species of microorganisms grown from pus. The changing clinical trends, microbiology, choice of antibiotics, usefulness of radiology, and complications of this potentially fatal illness are discussed.
