Biliary decompression: an institutional comparison of percutaneous and endoscopic methods

Endoscopically performed biliary drainage (EPBD) is now an alternative to percutaneous biliary drainage. The morbidity, mortality, and survival statistics of 97 patients with obstructive jaundice who had undergone percutaneous transhepatic biliary drainage (PTBD) and surgery, PTBD alone, EPBD and surgery, or EPBD alone were compared. Overall, the EPBD group had fewer complications and lower mortality than the other groups. When palliative treatment of patients with malignancies was compared, the complication rates associated with EPBD and PTBD were similar; however, mortality was lower with EPBD. No negative effect on survival was found with EPBD. In addition, EPBD offered several additional advantages over PTBD, including fewer bleeding complications, better patient acceptance, and avoidance of external catheter care. EPBD should be considered as a viable alternative to PTBD. Additional studies are needed to determine whether it is to be considered the initial drainage procedure of choice in patients with obstructive jaundice.     

tdic(9;12): a nonrandom chromosome abnormality in childhood B-cell precursor acute lymphoblastic leukemia: a Pediatric Oncology Group Study

In a review of 432 children with newly diagnosed acute lymphoblastic leukemia (ALL), we identified a new nonrandom translocation, tdic(9;12)(p1?1;p1?2), in the leukemic marrow cells of eight patients. Seven had hypodiploid karyotypes that lacked chromosomes 9 and 12 and contained a der(12), tdic(9;12); the eighth had a pseudodiploid karyotype with two normal 9 chromosomes, one normal 12 and the der(12), tdic(9;12). Abnormalities involving chromosomes other than 9 and 12 were noted in four of the eight patients. All cells with the tdic(9;12) expressed both the common ALL antigen and HLA-DR. Cytoplasmic immunoglobulin, a marker of pre-B ALL, was detected in one case with the tdic(9;12) but was absent in the other seven. Our results suggest that the tdic(9;12)(p1?1;p1?2) rearrangement is specifically associated with leukemic B cell precursors.     

Determining mandibular condyle and ramus height with the help of an Orthopantomogram®– a valid method?

summary The asymmetry of condylar and rami heights was determined from Orthopantomograms® of 25 macerated skulls and compared with the results of the 'true' values obtained by direct measurements of the skulls. The correlation between the two measuring methods was low.     

Lethal neonatal Menkes' disease with severe vasculopathy and fractures

A male neonate presented with an acute onset of severe intra-abdominal bleeding, haemorrhagic shock and multiple fractures leading to death on d 27. Menkes' disease was diagnosed at autopsy and confirmed by copper accumulation studies on cultured fibroblasts. Such an early onset of fatal complications in this condition has not been previously reported. New insights into the pathogenesis of Menkes' disease provided by DNA mutation analysis and difficulties in neonatal diagnosis are discussed. Menkes' disease should be considered in male infants with pathological fractures and other signs of connective tissue disease, even in the neonatal period.     

Dummies and the sudden infant death syndrome

The association between dummy use and sudden infant death syndrome (SIDS) was investigated in 485 deaths due to SIDS in the postneonatal age group and compared with 1800 control infants. Parental interviews were completed in 87% of subjects. The prevalence of dummy use in New Zealand is low and varies within New Zealand. Dummy use in the two week period before death was less in cases of SIDS than in the last two weeks for controls (odds ratio (OR) 0.76, 95% confidence interval (CI) 0.57 to 1.02). Use of a dummy in the last sleep for cases of SIDS or in the nominated sleep for controls was significantly less in cases than controls (OR 0.44, 95% CI 0.26 to 0.73). The OR changed very little after controlling for a wide range of potential confounders. It is concluded that dummy use may protect against SIDS, but this observation needs to be repeated before dummies can be recommended for this purpose. If dummy sucking is protective then it is one of several factors that may explain the higher mortality from SIDS in New Zealand than in other countries, and may also explain in part the regional variation within New Zealand.     

CAESAREAN SECTION — CHANGING TRENDS DURING LAST TWO DECADES

Changing trends of caesarean section during last twenty years have been studied. There seems to be a gradual increase in the incidence of caesarean section over the years with a simultaneous decline in the perinatal mortality rate. The incidence of caesarean section has slowly been increasing for post-caesarean pregnancy, breech presentation and foetal distress. This opens up a debate as to what extent this increase is justifiable. The trend needs a close observation.KEY WORDS: Cesarean section, Trends     

Cutaneous T-cell lymphoma treated with electron beam irradiation in Indian patients

BACKGROUND: Cutaneous T-cell lymphoma (CTCL) is a rare occurrence in India. Total skin electron irradiation (TSEI) is a well-accepted therapeutic modality for the treatment of CTCL throughout the world. The aim of this study was to retrospectively analyze the treatment outcome of TSEI in Indian patients with CTCL and to determine the different parameters affecting the disease-free survival in these patients. METHODS: Fourteen male patients between 27 and 82 years of age with CTCL (duration of disease, 4 months to 2 years) were treated with TSEI between 1985 and 1998. Seven patients had early stage disease, while the other seven had advanced disease. Two patients had lymph node involvement at the time of presentation. The TSEI was performed according to the Stanford technique delivering a total dose in the range 8-36 Gy. RESULTS: Of the 14 patients, 10 showed complete remission following TSEI. The total follow-up period was 4-110 months (median, 52 months). Five patients were disease free at the end of 5 years. Two patients died due to rapid progression of the disease, while the cutaneous lesions relapsed in three patients after 2-27 months and one patient developed visceral metastasis. CONCLUSIONS: TSEI was an effective therapeutic modality for the treatment of CTCL in this group of patients, both as a curative and palliative measure, although the long-term prognosis is poor.
