Conjoined lumbosacral nerve roots.

Conjoined lumbosacral nerve roots is a congenital anomaly that may produce lumbosciatic pain. When symptomatic and undiagnosed, it may be one of the causes of failed back syndrome. Diagnosis with water-soluble contrast myelography has a frequency of 4%. Anatomical studies have shown to have an incidence of 14%. High quality Magnetic Resonance Imaging (MRI) with coronal views may reveal this condition without recurring to computed tomography (CT)-myelography. In this paper we describe our recent experience with five consecutive cases observed during a one year period.

Stasis ulcers: the role of compliance in healing.

The goal in treating a stasis ulcer is rapid and permanent reepithelialization of the ulcer bed. The patient can reach this goal by strict compliance with a program taught and continually reinforced by the physician. The program teaches about the effects of the force of gravity on the flow of blood and lymph in the lower extremities in various positions. The program consists of three rules for the patient to follow: (1) Never sit with legs below heart level. (2) Never stand still. Walk in place or even while sitting (if sitting is necessary). (3) Always wear compressive stockings or pneumatic leggings when walking. I present four case histories demonstrating the different rates of healing of stasis ulcers during noncompliance and during compliance with the physiologic methods of controlling edema and venous stasis in the legs.

Drifting hematomas.

When blood is released into the tissues of the lower extremities, it may drift downward under the influence of the force of gravity to produce the influence of the force of gravity to produce pain, edema, redness and heat. A crescent shaped ecchymosis may appear around the malleoli. The relationship between cause and effect may be obscured by a time interval of up to four weeks before conclusive signs are seen. Early differentiation of this condition from that of phlebitis and deep venous thrombosis is necessary. Such differentiation prevents inappropriate and potentially dangerous anticoagulation as well as the disastrous consequences of untreated edema of the legs. With prompt, appropriate treatment, complete recovery can be expected. If treatment is delayed, permanent damage to the leg can result.

Intraluminal diverticulum of duodenum with associated diverticulitis and gastrointestinal bleeding.

A case of intraluminal diverticulum of the duodenum presenting with GI bleeding and associated focal diverticulitis has been added to the 39 other cases of intraluminal duodenal diverticulum previously described in the literature. The patient was treated surgically without difficulty after he was stabilized and evaluated by endoscopy and hypotonic duodenography.
