BRITISH MEDICAL JOURNAL 8 MARCH 1975 561 sensorineural loss a few hours after the explosion and when there are no contraindications related to the other injuries. In less severe cases it is our practice to prescribe vasodilator drugs and steroids, which appear to improve the recovery, though there is no controlled statistical evidence for this. ConclusionsOur experience with blast injuries shows that the ear has excellent properties of recovery after exposure to blast, with a high rate of spontaneous repair of the tympanic membrane and improvement of sensorineural deafness. Unfortunately this does not happen in every case, and some patients are left with residual perforations and permanent sensorineural deafness, often accompanied by tinnitus.All of the E.N.T. surgeons in Belfast have been involved in the nrnagement of blast injuries of the ear, and we wish to express our gratitude for the generous and co-operative way in which they have agreed to our reviewing both their notes and their patients. Summary Impaction of foreign bodies in the oesophagus was analysed in 54 patients, 45 of whom were children. Of the 45 children 28 were aged 2-4 years. Coins were the most common foreign body in children (27 cases) while in adults a bolus of meat was most common (nine cases). In 41 children there was no predisposing factor, but an underlying mechanism was detected in 88% of the adults. The mechanisms were of three types: oesophageal (stricture), neuromuscular (myasthenia gravis), and extrinsic and mechanical (ankylosing spondylitis). In children most of the foreign bodies were impacted in the upper oesophagus at the cricopharyngeal junction, which is the narrowest part of the oesophagus, while in adults the foreign body was usually impacted at the site of the predisposing lesion or in the lower oesophagus. In all patients oesophagoscopy was performed under general anaesthesia to remove the impacted foreign body. Complications were more frequent in adults, mainly owing to the underlying condition.

Febrile neutropenia (FN) is often observed in hematological malignancies (HEM). Presepsin is also known as soluble CD14 subtype; it is a glycoprotein fragment derived from monocytes and macrophages. We aimed to evaluate the significance of presepsin and other biomarkers for diagnosis of bacteremia in children with HEM. Sixty pediatric patients with different HEM (acute lymphoblastic leukemia 36, acute myeloid leukemia 12, non-Hodgkin lymphoma 10, and Hodgkin disease 2). Thirty age and sex-matched healthy children serving as control were enrolled in this study. Estimation of presepsin, procalcitonin (PCT), and C-reactive protein (CRP) during episode of FN in addition to absolute neutrophils count (ANC) and blood culture was performed for all the participants. Presepsin levels were higher in the patients than in control with a higher increments in the positive blood cultures than the sterile cases. Presepsin concentration was significantly higher in bacteremia than clinically proved infection and fever of unknown origin. A statistically significant positive correlation between presepsin and CRP plus PCT levels but negative correlation with ANC were observed in the patients subgroups. Presepsin is a useful marker for detection of bacteremia with sensitivity and specificity (100 and 85.7%). This finding supported that presepsin was superior to PCT and CRP in identifying bacterial infection in FN.
A prospective study was carried out for 6 months to determine the efficacy of blood ordering routines for elective surgery. It was found that only 23% of procedures needed preoperative crossmatching of blood (transfusion index 'TI' greater than 0.5). There was an excessive over-ordering of blood for 77% of the operations (crossmatch/transfusion ratio greater than 2.5). In addition, the transfusion index for the latter group showed that there was no need to prepare blood preoperatively (TI less than 0.5). A transfusion tariff is worked out which abandons crossmatching for the majority of procedures (cholecystectomy, thyroidectomy and surgery for duodenal ulcer excluding gastrectomy). Instead a 'group and screen' policy is suggested.
Ten cases of necrotizing fasciitis are reviewed. Three patients died but only two of these deaths were due to uncontrolled septicaemia. All isolated organisms were sensitive to a combination of piperacillin and ampicillin which we now regard as the initial antibiotic combination of choice. Prompt and aggressive surgical debridement remains the cornerstone of management.
Monitoring of minimal residual disease (MRD) is currently considered the most powerful predictor of outcome in acute lymphoblastic leukemia (ALL). Achievement of a negative MRD state assessed by multicolor flowcytometry (MFC) is an important predictor of disease-free survival (DFS) and overall survival (OS) in ALL patients. We sought to determine whether panels of antibodies combination are more suitable for detection of MRD in Childhood ALL. Eighty-four (84) patients with ALL (B-lineage subtype) were enrolled in this study. Normal template for B cell precursors was established in 15 control participants using 4-four panels of monoclonal Antibodies (Mo Abs),{CD22, CD45, CD58 and CD97 in combination with CD10, CD19, CD34}. At diagnosis, CD22 exhibited the lowest incidence of expression in only 50% of all patients, while CD45, CD58, and CD97 were expressed in 80.9, 59.5 and 92.8%, respectively. Analysis of MRD was performed for each Mo Abs combination at day 0 and day 14 post-induction of chemotherapy by 4-color (FCM). The incidence of MRD was 61.9, 70.6, 60.0 and 55.1% for CD22, CD45, CD58 and CD97, respectively. In B-ALL patients, (CD10/CD19/CD34/CD45) + (CD10/CD19/CD34/CD97) represented the highest incidence of expression of leukemic cells markers with a significant correlation with blasts count, suggesting that these are more specific for MRD detection. Also FCM is relatively cost effective for detection of MRD in ALL patients and its applicability in routine leukemia lab is valuable. MRD evaluation at the end of the induction therapy (i.e. day 35 or 42 according to the different schedules) is advised. Also, Ig/T cell receptor gene rearrangements and gene fusions analyzed by polymerase chain reaction (PCR) are preferred.
