Safe pre-operative fasting times after milk or clear fluid in children. A preliminary study using real-time ultrasound.

Gastric emptying of orange-flavoured glucose (group I), low-fat milk (group II) and breast milk (group III) was evaluated in 45 ASA grade I children of < or = 5 years of age by using real-time ultrasonography and residual gastric volume and pH was then measured. In 15 more children, residual gastric volume and pH was measured after a midnight fast (group IV). Mean (SD) gastric emptying time in group I was 1.53 (0.25) h (range 1.00-1.75), group II 2.32 (0.31) h (range 1.75-2.75) and group III 2.43 (0.27) h (range 2.00-2.75). According to Robert and Shirley's criteria, no children of group I and II were found to be 'at risk' at 2 h and 3 h, respectively, but 13.3% of group III children were labelled as 'at risk' at 3 h. The incidence of 'at risk' children in group IV was 33.3%. It was concluded that 3% fat milk or 17.5% glucose in a volume of 10 ml.kg-1 (maximum volume of 100 ml) can be given in children safely 3 h and 2 h, respectively, before anaesthesia. More real-time studies are required on breast milk to establish guidelines for its potential use as a pre-operative feed 3 h before anaesthesia.

Brainstem auditory evoked potentials among rubber factory workers.

The study was conducted on 27 rubber factory workers for the functional assessment of brainstem auditory pathway. Neurobehavioural questionnaire was administered to the workers and the personal sampler was used to evaluate the respirable particulate load inhaled per day of each worker along with qualitative analysis for PAH compounds. Evoked potential recording was carried out for brainstem auditory responses. Chest X-rays of workers exhibited varied abnormal features. Multiple regression analysis of data showed definite prolongation of latencies with increasing concentration of respirable particulate load though it was not statistically significant. Comparison with normative data indicated prolongation of latencies of rubber factory workers.

Diagnostic significance of excretory urography and ultrasonography in renal diseases.

A comparative study of intravenous urography (IVU) and ultrasonography (USG) was performed in 100 patients of all age groups, having symptoms and signs of various renal diseases. Sonography was found to be 100% sensitive and diagnostic in approximately 74% of renal pathologies included in this study, namely calculous disease (excluding midureteric calculi), obstructive lesions of pelvicalyceal system (PCS), cystic diseases, gross congenital lesions, traumatic lesions and neoplasms. It also provided information about the complications of long standing obstruction to PCS such as non-functional and atrophied kidneys, infection, etc. IVU proved better in midureteric calculi (100%), 88.2% of all congenital lesions including the major as well as minor variations. Both modalities proved to be of poor help in diffuse parenchymal diseases (IVU-40% and USG-50%) and renal tuberculosis (IVU-18.2% and USG-45.5%). Sonography was able to delineate the cause of obstruction to PCS in only 72.3% of cases as compared to 88% by IVU.

Roentgenographic evaluation of erosive changes in early cases of rheumatoid arthritis: using magnified view.

The diagnosis of typical cases of rheumatoid arthritis can be done on clinical grounds but problem arises in equivocal cases and radiological changes suggestive of rheumatoid arthritis help in confirmation or overweight the clinical diagnosis. Radiological changes viz, osteoporosis and soft tissue swelling can be assessed by conventional projections but problem arises in early detection of minute erosive changes of the articular surfaces. These lesions have been very well demonstrated by using magnification radiography and hence may be recommended for early diagnosis of rheumatoid arthritis.

Growth and sexual maturation of low birth weight children: a 14 year follow up.

OBJECTIVE: To evaluate the physical growth and sexual maturation of children born with low birth weight (< 2000 g). (LBW). DESIGN: Longitudinal follow up. SETTING: Hospital born urban cohort. METHODS: Weight, height, head circumference and pubertal changes were recorded till 14 years at specified intervals in 252 LBW and 176 control (term neonates with birth weights > or = 2500 g) children. Effect of prematurity and fetal growth retardation (SFD) was studied in 79 preterm appropriate for gestation and 45 term SFD children. RESULTS: LBW boys significantly lagged behind their controls for all physical growth parameters till 14 years, while the LBW girls had a physical growth comparable to controls after 11 years. Preterms had comparable weight, height and head circumference with their controls after 11 years. The SFDs, however, remained significantly handicapped in their overall physical growth even at 14 years. In comparison to controls, menarche occured 6 months earlier in preterms and 12 months earlier in SFD girls. However, there was no change in the sequence of pubertal changes in either preterms or SFDs. CONCLUSIONS: Fetal growth retardation has a lasting adverse effect on later physical growth, while most preterms catch up with their peers by adolescence.

Abnormal pattern of lung functions in rubber factory workers.

The influence of suspended particulate matter, benzo(e) pyrene, benzo(e) pyrene and benzo(a) anthracene concentration on pulmonary lung functions ie, residual volume, total lung capacity, residual volume/total lung capacity, forced residual capacity were studied in 667 rubber factory workers during 1990-91. The respirable fraction of the particulate size (< 0.5 micron) showed high mean concentration of suspended particulate matter, benzo(a) pyrene, benzo(e) pyrene and benzo(a) anthracene in the compounding section (group III), when compared with vulcanising (group II) and packing loading (group I) units. While comparing the lung functions amongst these groups, the higher results of residual volume, residual volume/total lung capacity ratio, forced respiratory capacity and lower values of total lung capacity were observed in group III workers as compared with other two groups. And also these results seem to be correlated with the high pollutant concentrations to which group III workers were exposed, and reflect a clear combination of obstructive and restrictive pattern of lung functions in them.

A study of extra-auditory effects of noise.

Paper mill workers (106) exposed to noise ranging from 80 to 96 dBA were assessed for alteration in clinical status. Neurobehavioral functions were examined with the help of a questionnaire. The study did not reveal any changes attributable to noise in subjects exposed to 86-90 dBA and > 90 DBA noise in course of their occupations.

Broken tracheostomy introducer--an unusual tracheobronchial foreign body.

We present a rare case where the introducer of a metal tracheostomy tube became lodged in the tracheobronchial tree. This may be the only reported case. The literature is reviewed to study the possible cause of tracheostomy tube component fracture and to suggest methods for preventing this complication.

Leiomyosarcoma of gallbladder: a case report.

A case of leiomyosarcoma of gallbladder, a rare tumor in hepatobiliary region, is reported. The present case differs from previously reported cases in its presentation with empyema of gallbladder and multiple intrahepatic cholangiolytic abscesses. Curative surgery could not be undertaken on account of poor condition of patient, and invasion of tumor into liver and adjacent organs.

Acute osteomyelitis: early diagnosis by ultrasonography.

A prospective study was carried out to evaluate the role of ultrasound in early detection of infections of bone. Presence of a hypoechoic collection adjacent to bone was considered highly suggestive of osteomyelitis whereas a hypoechoic collection away from the bone implied a soft tissue abscess. Cellulitis presented as increased subcutaneous thickness. Of the 31 patients clinically suspected to have osteomyelitis, and subjected to ultrasound, 25 were proven to be osteomyelitis at surgery or by subsequent radiological changes, 4 had soft tissue abscesses and the remaining 2 had cellulitis. Co-existent hip joint effusion was seen in 2 patients. It is felt that ultrasound is simple and non-invasive investigation, capable of detecting bone and soft tissue infections.
