In a prospective, randomized study of 16 volunteers, a new galenic formulation of the induction hypnotic etomidate in lipid emulsion was compared with the commercial form in propylene glycol (Hypnomidate). After 0.3 mg/kg etomidate plasma levels (HPLC) and hypnotic effects (visual EEG analysis) of both formulations were almost identical. Onset of action occurred after 41.6 s in the propylene glycol group (group I) and 35.6 s in the lipid emulsion group (group II). The hypnotic effect (greater than or equal to D0) lasted 7 min 20 s in group I and 6 min in group II. Plasma levels in group I decreased from 630 ng/ml after 2 min to 170 after 8 min and 37 after 130 min. With group II the plasma levels decreased from 770 ng/ml after 2 min to 150 after 8 min and 42 after 130 min (Fig. 1). In the propylene glycol experiment, 4 of 8 volunteers reported pain on injection. Within 7 days 4 persons developed phlebitis or thrombophlebitis. One showed signs of an allergic reaction (urticaria). With the new formulation of etomidate in lipid emulsion, neither venous sequelae nor allergic reactions were observed in any of the 8 volunteers (Table 2).

Cannulae made of polytetrafluoroethylene (PTFE: n = 11), thermoplastic polyether-urethane (TPEU: n = 11), and a new test material, polyamide-ether-elastomer (XLON: n = 10) were inserted into the veins of the dorsum of the hand in 32 healthy volunteers (10 women and 22 men), 21-50 years old. The cannulae were intended to be left in place for 5 days. No infusion was given and the dressings were not exchanged. The resulting thrombophlebitis, defined as two or more of the symptoms pain, redness, oedema and hardness, was estimated on a scale which took into account the incidence, location, intensity, and duration of the symptoms. Except for one volunteer in the XLON group, all the volunteers developed thrombophlebitis, generally observed on the third day of cannulation, and being more frequent and intense over the cannulae (P less than 0.001) and at the tip (P less than 0.01) than at the insertion sites. Pain and oedema were, on the whole, the most frequent and severe symptoms during the period of indwelling. After withdrawal, hardness was the most intense, and together with pain, the most long-lasting (up to 10 days) symptom. The differences between the materials in thrombophlebitis incidence and intensity were statistically significant only when each symptom was analysed separately. Thus, the PTFE cannulae caused more pain and hardness (probably because of greater platelet adhesion and a relatively greater stiffness), while the TPEU and XLON cannulae produced more periphlebitis (redness and oedema), probably because of potentially irritant and antigenic substances leaking from them (polyurethane oligomers and polyamide/polyethyleneglycol oligomers).

Between January 1 1974 and October 31 1987, 98 patients with biopsy proven unresectable adenocarcinoma of the pancreas were treated with I-125 implants during laparotomy. Presenting symptoms were pain (57 patients), jaundice (45 patients), and weight loss (34 patients). All patients underwent laparotomy and surgical staging. Thirty patients had T1NoMo disease, 47 patients had T2-3NoMo disease, and 21 patients had significant regional lymph node involvement (T1-3N1Mo). The surgical procedure performed was biopsy only (16 patients), gastric bypass (36 patients), biliary bypass (49 patients), and partial or total pancreatectomy with incomplete resection (5 patients). The total activity and the number of seeds used were determined from the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Stereoshift localization X ray films were taken 3-6 days after operation. The mean activity, minimal peripheral dose (MPD), and volume of the implants were 35 mCi, 13,660 cGy, and 53 cm3, respectively. In addition, 27 patients received postoperative external irradiation and 27 patients received chemotherapy. Postoperative complications were observed in 19 patients. These included post-operative death (1 patient), biliary fistula (4), intraabdominal abscess (4), GI bleeding (3), gastric or small bowel obstruction (6), sepsis (5), and deep vein thrombophlebitis (4). Pain relief was obtained in 37/57 patients (65%) presenting with pain. A multivariate analysis showed that four factors significantly affected survival: T stage, N stage, administration of chemotherapy, and more than 30% reduction in the size of the implant on follow-up films. The median survival for the entire group was 7 months. A subgroup of patients with T1No stage disease who received chemotherapy survived 18.5 months. The indications for I-125 seed implantation in unresectable carcinoma of the pancreas are discussed.

Ovarian vein thrombophlebitis is often misdiagnosed because of vague symptoms leading to unnecessary surgery, morbidity, and mortality. CT findings in such a case are very useful in making a definite diagnosis of ovarian vein thrombophlebitis. We consider CT the preferred method for evaluating pain in the right lower quadrant associated with a mass in the postpartum patient.

A 26-year-old male shortly after an acute respiratory disease was affected by a thrombophlebitis of the left leg. After a few days he had two syncopal attacks. Later on, a myocardial ischemia was diagnosed. Subsequently the patient began to complain of a bilateral claudication of the calves; after an attack of fever, the ischemia of the lower limbs worsened with recurring pain at rest. At the same time, in absence of any symptom, a myocardial ischemia occurred again and the presence of a thrombus was observed in the right atrium. After surgical removal of it, the ischemic troubles of the lower limbs once again began to worsen with the occurrence of bilateral gangrene of the feet. An amputation of both the legs was promptly performed at the level of the thighs. The histological examination of the arteries of the amputated legs showed segmental arteritis with partially recanalized thrombi of the popliteal, left femoral and tibioperoneal arteries. In the meantime, the titres for Coxsackie virus B2 and B6 were found slightly increased. One month later, the left radial pulse disappeared for a few days. The histopathological findings may relate this arteritis to a form of Buerger's disease even if a systemic thromboangiitis obliterans is not commonly accepted. In case that the acute respiratory infection represented the true onset of the sickness, it seems conceivable that the hypothesis of a viral infection gave raise to arteritis with morphological features recalling those of Buerger's disease.

Two hundred patients requiring sedation for minor oral surgery were randomly allocated to receive either midazolam or diazepam as Diazemuls intravenously through a 23-gauge indwelling needle in the dorsum of the hand. The site of injection was inspected at 7 days and 14 days post injection and assessed for pain, tenderness, redness, induration, painless thrombosis, and thrombophlebitis. The mean dose administered was 0.119 mg/kg of midazolam and 0.298 mg/kg of Diazemuls. At 7 days there was no significant difference in venous complications. At the 14 day follow up, the midazolam group had a significantly greater incidence of tenderness and redness (p less than 0.001 and p less than 0.05 respectively using Chi squared test). The incidence of thrombophlebitis in the midazolam group was 2% at 7 days and 1% at 14 days, the corresponding figures in those given Diazemuls being none and 1% respectively. We conclude that the dorsum of the hand is a satisfactory site of injection for administration of these drugs. The higher incidence of minor complications at 14 days following midazolam was offset by its more reliable amnesic properties.

The causalgic form of the postphlebitic syndrome or reflex sympathetic dystrophy resulting from acute deep thrombophlebitis is a relatively uncommon and, unfortunately, frequently unrecognized form of the postphlebitic syndrome. The usual signs of venous insufficiency are minimal, but severe burning pain is characteristic, usually increased by dependency. The diagnosis is confirmed by phlebography and the response to a lumbar sympathetic block. A lumbar sympathectomy produces permanent pain relief.

Orbital venous vasculitis has been suggested to cause characteristic periorbital pain in patients with pathologic changes in their orbital phlebograms. The orbital pain is characterized by being unilateral, not shifting side, boring and pressing, but not throbbing, increasing on eye strain, exposure to cold, or weather changes, and resistant to analgesics. It is ameliorated by steroids. Fifty patients with symptoms of orbital venous vasculitis were investigated for other symptoms that could be related to the vasculitis. When the 32 female patients were compared with a randomly selected age- and sex-matched control group, there was a significant increase of symptoms of chronic fatigue, cold feet, gut problems such as constipation and/or diarrhea, arthralgia, memory impairment, rotatory vertigo, spontaneous ecchymoses (all, p less than 0.0001), back pain (p less than 0.012), and thrombophlebitis (p less than 0.022) in the patient group. These symptoms, although commonly occurring, seem in these patients to be related to the vasculitis. Blood tests of the fifty patients showed signs of inflammation which did not disagree with the hypothesis of an immunologic cause of the orbital venous vasculitis.

Intravenous diazepam was compared with intravenous midazolam for conscious sedation in a single-blind study of 50 Hong Kong Chinese patients acting as their own controls. Verrill's sign was used as the end-point of sedation, and bilateral, similarly impacted lower third molars served as the surgical model. The drugs produced comparable levels of sedation, stable vital signs, and good operating conditions in all patients. Midazolam had numerous advantages over diazepam: more rapid onset of sedation, less pain during injection, profound anterograde amnesia, and fewer postoperative complications. The incidence of thrombophlebitis was low with both drugs and appears to be so in Chinese in general. A significant majority of the patients preferred sedation to other techniques and midazolam to diazepam.

A 55 year-old woman was admitted to hospital in January 1981 with transient expressive dysphasia. Past personal history was unremarkable except for a six-month history of renal colic and thrombophlebitis in the veins of the right leg. Computed tomographic scan of the head and carotid angiogram revealed a left calcified temporoparietal tumor. Because of pulmonary embolism it was decided to refute a cerebral biopsy. The patient also declined radiotherapy. In May 1983, a thorough workup revealed an incomplete fracture of the first lumbar vertebra and a diffuse demineralization of the rachis and pelvis. Four weeks later she developed temporal epilepsy and pulmonary embolism. A whole brain irradiation (60 Gy) was performed in August 1983. The patient's condition remained clinically stable until December 1984 when she was readmitted to hospital with a severe weight loss, diffuse osseous pain and pancytopenia. A bone marrow biopsy from the iliac crest showed a diffuse tumor involvement. Peroxidase-antiperoxidase staining using monoclonal antiserum to glial fibrillary acidic protein was strongly positive in numerous tumors cells. The pathological diagnosis was bone marrow metastasis by glioma. She died in March 1985, 4 years and 3 months after the first admission to hospital. Autopsy was not performed. A literature search reveals only 9 cases of extraneural spreading of astrocytomas and glioblastomas in the absence of previous craniotomy with post-mortem examination. The authors also comment on the clinical, pathological and histogenic aspects of extraneural metastasis of gliomas.
