Ethical issues in professional advertising.
Physician advertising has received considerable attention since the courts decided in favor of the Federal Trade Commission (FTC) in its initial complaint against the American Medical Association in the 1970s. Continued investigations by the FTC into AMA opinions on advertising and publicity have promulgated a new freedom in advertising by physicians. False and deceptive advertising though is the grounds for court action as well as license revocation. This is an attempt to analyze where physician advertising is most prevalent, which physicians are doing it and why.
Nut-like oil seeds: food for monkeys, chimpanzees, humans, and probably ape-men.
The hypothetical hyperrobust australopithecine gnathic nutcracker adaptation is reexamined in light of ecobotanical information on edible wild nuts provided by the flora of tropical and subtropical Africa. The nut producing species are tree-forms. Those of the forest region do not as a rule produce fruits with edible mesocarps. In contrast, the woodland savanna species (particularly in the Zambezian region) characteristically provide an important whole fruit, i.e., a nutritious mesocarp in addition to edible oil-rich nut seeds. These fruits drop from the tree before they are fully mature and go through the final ripening phase on the ground. They are important seasonal foods for a variety of vertebrates, including primates, elephants, and antelope. Altogether the nuts exhibit a broad range of toughness values, measured here as strength under compression. The woodland nuts are not as tough (177-934 kg force, breaking load) as those of the tropical forest (192-1,673 kg force). The seed-predators of the woodland species include squirrels, baboons, warthogs, and parrots. Paleoecological analyses indicate that it was the woodland nuts that were probably available to Australopithecus boisei and A. robustus. Preliminary estimates of adult male gnathic nut-cracking capabilities suggest that A. boisei could have orally cracked a significant portion of the woodland nuts. In spite of this, ecobotanical data indicate that we can probably reject the hypothesis that these hominids were year-round gnathic nut-cracking specialists. Both the indirect and direct evidence support this conclusion.
Emergency care of the injured hand.
A multitude of hand injuries are occupationally related. The scope of such injuries and the appropriate initial care of each is discussed. The ultimate outcome following an occupationally related hand injury is frequently determined by the initial care rendered.

The arc of the latissimus dorsi myocutaneous flap.
An anatomical description of the latissimus dorsi muscle, together with that of the latissimus dorsi myocutaneous flap, is presented, with examples of its versatility for reconstruction.

Surgical management of ulcers on the lower limbs.
Ulcers on legs may result from venous hypertension or arterial insufficiency. Ulcers of either type require skin cover. Methods of achieving such cover are explored.
Reconstruction of the hypopharynx and cervical esophagus with microvascular jejunal transplant.
A method of replacement of the hypopharynx and cervical esophagus utilizing a microvascular jejunal transplant has been presented. This has been found to be a clinically acceptable and reliable method of repair. Its primary advantage compared with other methods of reconstruction is that it is a one-stage repair with a lower incidence of postoperative complications.
Activity of nocturnal primates: influences of twilight zeitgebers and weather.
The time of onset of activity of bush babies (Galago senegalensis), slow lorises (Nycticebus coucang), and an owl monkey (Aotus trivirgatus) living in outdoor enclosures usually fell in certain illuminance ranges of dusk and kept pace with seasonal progressions of sunset time. Influences of cloud cover were variable, but excessive heat and cold were inhibitory. Accurate endogenous timekeeping and reliance on the most stable zeitgeber apparently maintain activities in synchrony with the rhythmically changing environment.
Office and emergency room care of the injured hand.
A careful initial evaluation and proper treatment of the injured hand can minimize morbidity and assure early recovery. Various hand injuries encountered and their appropriate treatment are discussed. Emphasis is placed on the initial care, and in some instances the definitive treatment, which can be given in the physician's office or the hospital emergency room.
Twilight zeitgebers, weather, and activity of nocturnal primates.
Bush babies (Galago senegalensis), slow lorises (Nycticebus coucang), and an owl monkey (Aotus trivirgatus) in outdoor enclosures usually began activity in certain illuminance ranges of dusk and accommodated to seasonal changes in sunset time. Influences of cloud cover were variable, but marked heat and cold were inhibitory. Accurate endogenous timekeeping and a reliance on the most stable zeitgeber apparently maintain activities in synchrony with the rhythmically changing environment.
