Ultra-intense short-pulse lasers interacting with matter are capable of generating exceptionally bright secondary radiation sources. The short pulse duration (picoseconds to nanoseconds), small source size (sub-mm), and comparable high peak flux to conventional single particle sources make them an attractive source for radiography using a combination of particle species, known as multimodal imaging. Simultaneous x-ray and MeV neutron imaging of multi-material objects can yield unique advantages for material segmentation and identification within the full sample.

Objectives: To compare the efficacy of wide excision operations and minimal trephine surgery in patients with primary pilonidal disease.
Background: Hemorrhoids are a common disorder that affects the quality of life of millions of people worldwide. The effectiveness of OTC medication is limited and they mainly provide symptomatic relief. In order to treat this ailment, we formulated PP110 Gel and Wipes, as a novel treatment for hemorrhoids.

The authors hypothesize that palmar hyperhidrosis is a systemic manifestation of abnormal sudomotor function; consequently, thoracoscopic sympathectomy to alleviate symptoms in the hands may result in heat dissipation because sweating is transferred to other sites. To investigate this phenomenon and to determine whether it adversely affects patient satisfaction, a standard questionnaire was administered to 626 patients who underwent sympathectomy at a university-associated public hospital between 1991 and 1998; only patients treated at least 6 months before questionnaire distribution were included in the study. Replies were received from 336 (53.

The disorder usually is accompanied by other congenital anomalies on the same limb or other parts of the body. A report is made of 22 limbs observed in 18 patients from 1970 to 1987 at San Juan de Dios Hospital in Caracas, Venezuela, with more than a 5-year follow-up.

Abdominal compartment syndrome is still a controversial entity. We report on a patient who developed the classical hemodynamic, respiratory, and renal changes of abdominal compartment syndrome after surgical intervention for blunt abdominal trauma. A decompressive laparotomy improved the situation dramatically.

Four groups of animals (each group numbering 30 mice) were studied. Group 1 consisted of sham operated mice and served as the control group.

We have shown recently that treatment with CsA preoperatively overcomes the suppressive effect of flushing and returns the regenerative response to a normal time scale. The present study was designed to investigate whether administration of FK506 would also return the observed delayed regenerative response to normal.

Between 1971 and 1987, we treated 26 patients with congenital absence of the radius which had produced a club hand; 37 hands were affected. Treatment before the age of 8 months was by gentle manipulation and serial plasters. If a functional position was not obtained, and in patients over 8 months, surgical reduction was carried out.

Surgically excised "parathyroid glands" were found to be, in fact, large lymph nodes with sarcoid granulomata. In one patient, the preoperative localization of the "parathyroid adenoma" was based on scintigraphy (thallium-technetium subtraction imaging) and sonography procedures.

We have reviewed all endoscopies performed in our hospital between 1977 and 1986. During that period, 1337 endoscopies were performed to identify bleeding from peptic ulcers. Excluded were cases in which a predisposing factor was found, such as the use of ulcerogenic drugs.

Design: Open study.
Subjects: Seven consecutive patients treated for perineal suppurative hidradenitis during the past three years, and 10 control subjects who were being treated for acute cryptogenic perianal abscesses.
The hormone somatostatin, a tetra-deca-peptide, was discovered in 1972. It inhibits the central nervous system and the endocrine and exocrine secretions of the gastrointestinal tract. The first clinical use of the hormone was to inhibit hormone-secreting tumors of the CNS.

The effect of leukotriene and prostaglandin antagonists on hemodynamic response and survival of rats after superior mesenteric artery (SMA) occlusion was investigated. The animals were divided into five groups: in group 1 (n = 105) the SMA was clamped for 2 h and mortality assessed after 24 h.
