Combat and personality change.

In response to combat, some soldiers develop a feeling of satisfaction in killing. The authors label this reaction the "heart of darkness experience," after the story by Joseph Conrad (1903/1982). They describe their clinical experience of seeing this response as part of a spectrum of reactions ranging from no personality change to rather gross personality change. After exploring psychological factors involved in this change, they suggest relevant treatment considerations.

The love of war: Vietnam and the traumatized veteran.

Many veterans treated for posttraumatic stress disorder (PTSD) keep alive their war experiences because of their significance and meaning. For these veterans, combat was a positive as well as a negative experience. The authors suggest that many veterans suffer from PTSD because they are continuing to live out their war experiences and to hold onto the meaning of these experiences. Effective treatment requires these veterans to develop a competent peacetime self that incorporates the positive features of the warrior identity.

Cystic adventitial disease of the popliteal artery.

Cystic adventitial disease of the popliteal artery has been recognized as a cause of arterial stenosis and calf claudication for 30 years. It is reported infrequently and its etiology remains unknown. In addition, a peculiar geographic distribution of the reported cases of this disorder has been noted, with a majority of cases from Europe and Australasia. The authors report here a case from South Carolina in which a fibrous band may have contributed to compression during exercise. Noninvasive studies and angiographic studies were negative before exercise and positive after exercise. Current ideas of diagnosis, surgical treatment and possible etiology are presented.

Diagnosis and management of thoracic outlet syndrome.

During the past 15 years, using plethysmography and maneuvers originally described by other researchers, we have tested 1,140 patients who had thoracic outlet symptoms. The vascular compression was recorded noninvasively, which also reflected the pressure on accompanying nerves in the brachial bundle. If the neurologic symptoms were reproduced at this time, the diagnosis of thoracic outlet syndrome was positive. Following exercise treatment (without improvement), 194 patients underwent operative exploration. By performing costoclavicular and hyperabduction maneuvers during axillary exploration, the tissue causing compression was identified and the muscle, bone, or tendon was divided or resected. Division of soft tissues in 180 patients resulted in improvement in the conditions of 173 patients (96%). Bone resection allowed relief of symptoms in six (43%) of 14 patients.

Negative phleborheography: clinical follow-up in 593 patients.

Approximately 500,000 cases of pulmonary embolism appear each year in the United States, with most having clots that originated in the deep veins of the lower extremities. Since the clinical diagnosis of deep venous thrombosis (DVT) is accurate only half the time, a safe method that affords immediate and definitive diagnosis of DVT is urgently needed. One diagnostic technique now available is phleborheography (PRG). We examined 1,076 patients (2,152 limbs) during the period of 1976 to 1979. By performing PRG before hospital admission, 392 patients who had negative study results were not hospitalized, resulting in an estimated savings of +960,400 and avoiding both the hazardous treatment and the stigma associated with a diagnosis of DVT. After one to three years of follow-up in 593 patients (1,186 limbs) who had had negative results from PRG, only three (0.5%) have shown evidence of postphlebitic swelling and one (0.2%) has had pulmonary embolus.

A noninvasive method to assess sympathetic activity.

Reflex adjustments of the blood flow through the skin are mediated largely by the sympathetic nervous system and play a fundamental role in the regulation of body temperature. Since blood flow in the digits is almost entirely through skin vessels, surface temperature measurements and digital plethysmography are useful methods of studying the changes in digital blood flow. Sweating is also primarily controlled by the sympathetic system and can be monitored by measuring the electrical resistance of the skin. A noninvasive test to assess sympathetic activity is described comparing the findings in normal subjects and patients with arterial diseases, vasospasm, and diabetes. Digital arteries obstructed by diseases or clot can be delineated from obstruction due to vasospasm, and diabetic neuropathy can be objectively identified. Follow-up studies in more than 1200 patients have demonstrated that an accurate prediction of the outcome of sympathectomy or nonoperative treatment can be made after assessing the results of this safe and inexpensive noninvasive test.
