Solitary cavities of the lung: diagnostic implications of cavity wall thickness

Sixty-five solitary cavities of the lung were evaluated for wall thickness. All lesions in which the thickest part of the cavity wall was 1 mm were benign. Of the lesions whose thickest measurement was 4 mm or less, 92% were benign. Of cavities that were 5-15 mm in their thickest part, 51% were benign and 49% malignant. Of those over 15 mm thick, 95% were malignant. Measurement of the thickest part of te cavity wall gives a more reliable indication of benignancy or malignancy than measurement of the thinnest part.     

Extracorporeal shock wave lithotripsy (ESWL) in the management of complex biliary tract stone disease.

The use of extracorporeal shock wave lithotripsy (ESWL) in the management of ten patients with complex biliary tract stones is described. General or epidural anesthesia was used in all cases, and stone fragmentation was performed, using an unmodified Dornier HM3 waterbath lithotripter (Dornier Medical Systems Inc., Marietta, GA). In all cases, biliary drainage was established before the procedure to allow contrast visualization during and after the procedure, as well as to ensure free drainage of the common bile duct. Indications for ESWL included failure of basket extraction (4 cases), unfavorable anatomy (duodenal diverticulum, previous Billroth II reconstruction, hepatic duct stone, gallbladder stone, cystic duct remnant stone), and immaturity of the T-tube tract (2 cases). Cholangitis was the presenting diagnosis in four cases. Fragmentation of the stones was successful in all patients; in two cases, two ESWL sessions were needed for stone disruption. Morbidity was minimal (there was a minor elevation of LDH and transaminases and asymptomatic hemobilia and hematuria); pancreatitis did not occur. After ESWL, hospital stays ranged from 1 to 13 days (mean of 5.3 days). ESWL can be a valuable adjunct in the management of patients with complex biliary stones.     

Editorial

The present study was conducted to determine whether older adults can learn and retain information on asthma and play a role as community health workers to teach children about asthma. A total of 36 older adults and 28 students in grades K-6 participated. Pre-tests and post-tests were administered to participants. Improvement in older adult scores after training was significant (p =. 001), and improvement persisted through the conclusion of teaching sessions (p = 0.001). The increase in lower student scores was significant (p = 0.050). Results suggest that older adults can learn and retain asthma information and schoolchildren can learn asthma-related information taught by older adults.     

Collar spine models in the genus <Emphasis Type="Italic">Echinostoma</Emphasis> (Trematoda: Echinostomatidae)

This paper discusses collar spine arrangements in the genus Echinostoma. All arrangements are of uneven numbers of collar spines on the oral collar. The total number of collar spines in these arrangements ranges from a low 31 to a high 51. There are 11 models of collar spine arrangements in the Echinostoma consisting of spine numbers 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, and 51. Representative species with these collar spine arrangements are given in the article. The number of collar spines in a species is identical in both the larval and adult forms. Reports of even numbered spine counts in the genus Echinostoma are erroneous and probably reflect counts on worms with lost, retracted, or supernumerary spines.     

Effects of partial hepatectomy on extrarenal erythropoietin production in rats

Studies were performed to determine the effects of partial hepatectomy on extra-renal erythropoietin production. Rats were either partially hepatectomized or sham operated. At intervals of from 5 min to 7 days afterward, both kidneys were removed from cohorts of the above two groups of rats and the animals were then exposed to hypoxia for 7.5 hr. Immediately afterward, their plasma was collected and its erythropoietin titer was assayed. Rats which were partially hepatectomized 2-4 days prior to nephrectomy and hypoxia had significantly higher plasma erythropoietin levels than did sham- operated controls, whereas rats hepatectomized 5 min, 1 day, or 7 days prior to nephrectomy and hypoxia did not. These data are consistent with the conclusion that extrarenal erythropoietin production is enhanced in association with rapid regeneration of hepatic cells.
