Abstract
Thirteen cases of concomitant trochanteric and shaft fracture of the same femur are reported. The hip fracture was initially missed in two cases. Osteosynthesis of both fractures was performed in ten cases. Both fractures healed in the 12 cases followed for 6 months or more. Osteosynthesis of both fractures is recommended, preferably by fixation with angled or straight plates, and Ender nailing in selected cases.

Abstract
The Roux-en-Y anastomosis is a surgical procedure performed to divert the pancreaticobiliary juices from the gastric pouch in patients who have alkaline reflux gastritis or esophagitis, or both, that develop after vagotomy and Billroth I or II operations. After the Roux-en-Y procedure the inflammation subsides but is often replaced by a characteristic group of symptoms--chronic abdominal pain, nausea, and vomiting worsened by eating. Using a semiconductor recording probe, we investigated the Roux limb in 7 subjects who were fasted and then fed (liquid and solid meals). In the fasted state the migrating motor complex was either completely absent or grossly disrupted. Only 1 subject converted to a fed-state motility pattern in the Roux limb after a liquid meal (Osmolite), and all 7 subjects failed to convert to a fed state after a solid meal. These studies suggest that the Roux-en-Y syndrome of pain, nausea, and vomiting is secondary to a defect in motor function and that the Roux limb is acting as an area of functional obstruction.

Abstract
A purified Shigella enterotoxin (pST) and a cell-free lysate with pST removed (CFL-pST) from the whole-cell lysate of Shigella dysenteriae 60 R were used to study their effect on the myoelectric activity and mucosal integrity of rabbit ileal segments. We have previously defined two myoelectric patterns: the migrating action potential complex and repetitive bursts of action potentials that occur in response to certain bacteria and their enterotoxins. The in vivo model consisted of isolated ileal segments in male New Zealand White rabbits. The segments were infused with sterile saline (1 ml/h), pST (2.4-micrograms injection), or CFL-pST (1 ml/h). Myoelectric activity in the segments exposed to pST was similar to that with the saline infusion, but CFL-pST induced significant alterations in myoelectric activity in the form of repetitive bursts of action potentials. The mucosa of the segments exposed to pST showed only mild inflammatory changes. In contrast, CFL-pST caused moderate to severe inflammatory changes with enterocyte necrosis. These studies show that pST, a known enterotoxin, did not alter myoelectric activity and had no significant effect on the integrity of ileal mucosa, as determined by light microscopy. CFL-pST caused both inflammation and tissue necrosis with significant alterations in motor activity. These studies suggest that S. dysenteriae 60 R produces a substance or substances other than pST that cause florid in vivo cytotoxicity and alter myoelectric activity.

Abstract
Wound healing calls for little outside interference. All the physician need do is ensure that the wound is clean and debrided and decide whether closure by suture or by granulation tissue formation is indicated. Suture repair should be delayed if the wound is heavily contaminated. Use of skin tapes or of constant-pressure garments may enhance results.

Abstract
Nutrient malabsorption and diarrhea are characteristic of the blind loop syndrome. Alterations in motility have been implicated as a cause of bacterial overgrowth, but the possibility that altered motility may result from alterations in the flora has not been explored. The purpose of this study was to characterize the myoelectric activity of the small intestine in the blind loop rat model. Eight groups of rats were studied: rats with self-filling blind loops, which develop bacterial overgrowth; rats with self-emptying blind loops, which are surgical controls that do not develop overgrowth; unoperated litter mates; rats with self-filling blind loops and unoperated controls treated with chloramphenicol, 200 mg/d i.p.; rats with surgically removed self-filling blind loops; operated control rats; and gnotobiotic rats with self-filling blind loops. In the untreated rats with self-filling blind loops, there was altered myoelectric activity characterized by an increased percentage of slow waves occupied by action potentials and by organized activity similar to the migrating action potential complex. Migrating action potential complex activity and percentage of slow waves occupied by action potentials were significantly decreased with chloramphenicol therapy; that decrease correlated with a decrease in aerobes and anaerobes. Migrating action potential complex activity was abolished in rats with surgically removed self-filling blind loops; they also showed a significant decrease in percentage of slow waves occupied by action potentials. Gnotobiotic rats with self-filling blind loops showed no alteration in myoelectric activity. These data indicate: (a) bacterial overgrowth is associated with a significant increase in percentage of slow waves occupied by action potentials and migrating action potential complex activity; (b) chloramphenicol significantly reduced both percentage of slow waves occupied by action potentials and migrating action potential complex activity; and (c) surgical removal of the loop reduced the alterations in motor function. This study suggests that the altered myoelectric activity in this model of bacterial overgrowth was due, in part, to the abnormal bacterial flora and supports the concept that alterations in motility may contribute to the diarrhea that is characteristic of the blind loop syndrome.

Abstract
Among the different etiologies of noncardiogenic acute pulmonary edema is found the administration or ingestion of various substances. We have studied two patients with ARDS secondary to the ingestion of toxic oil. Both patients presented similar roentgenographic findings characterized by interstitial and alveolar infiltration in "butterfly" distribution, pleural effusion, and a normal cardiac silhouette. The two cases also showed a pulmonary compliance either normal or slightly diminished. With the aid of artificial ventilation, they evolved favorably, gaseous exchange and chest x-ray films returning to normal 16 and 22 days after admission.

Abstract
When C3H/10T1/2 cells are treated with a given concentration of a chemical carcinogen, the transformation frequency can vary over 4 orders of magnitude, depending primarily upon the number of cells plated. To explain this phenomenon, we have developed a probabilistic theory of the formation of transformed foci in this system. We define p1 as the probability that a cell will be activated by carcinogen treatment, p2 as the probability per cell generation that an activated cell will be transformed, and p3 as the probability per cell generation that an activated cell will be deactivated. The equation we have derived: log (F/N) = log [2p1p2(1 -- p3)/2(1 -- p3) -- 1]+ n log (1 -- p3) describes focus formation; F is mean number of loci per dish after carcinogen treatment, N is number of cells in a dish at confluence, and n is number of cell generations to confluence. This equation has been verified experimentally; p3 = 0.24 and p1p2 = 3.8 X 10(-6) at a single concentration of 3-methylcholanthrene. This relationship explains previously inexplicable effects of cell density on transformation frequency.

Abstract
A multicentre study of antibiotic susceptibility was performed in South Africa. Sensitivity to cephalothin, cefamandole, tobramycin and gentamicin was tested on a variety of aerobic and anaerobic bacteria. Two disc susceptibility techniques were used, i.e. the Kirby-Bauer technique (aerobes) and the broth-disc method (anaerobes); minimum inhibitory concentrations (MICs) were determined according to the International Collaborative Study techniques, and regression lines for individual centres were constructed. Satisfactory lines were obtained for cephalosporins, but, in some centres, problems were experienced with the aminoglycosides. Variations in MICs for Haemophilus influenzae were probably due to an inoculum effect. Accumulative percentage tables of the number of strains inhibited were compiled, and the comparative performance of the antibiotics was assessed.
