The Children's PTSD Inventory: development and reliability.

Information involving the development of the DSM-IV version of the Children's PTSD Inventory is described. Independent ratings by highly experienced judges denote that the instrument encompassed the universe of definition that it was intended to measure (i.e., the DSM-IV criteria for PTSD). The instrument was administered to 82 traumatized and 22 nontraumatized youths at Bellevue Hospital. Moderate to high Cronbach alphas (.53-.89) were evident at the subtest level. An alpha of .95 was evident at the diagnostic level. In terms of inter-rater reliability, 98.1% agreement was evident at the diagnostic level. Inter-rater intraclass correlation coefficients (ICCs) ranged from .88 to .96 at the subtest level and .98 at the diagnostic level. Good to excellent kappas (.66-1.00) were reported for inter-rater reliability at the subtest level. An inter-rater reliability kappa of .96 was evident at the diagnostic level. In terms of test-retest reliability, 97.6% agreement was evident at the diagnostic level. Good to excellent test-retest kappas (.66-1.00) and ICCs (.66-.94) were observed. A test-retest kappa of .91 and an ICC of .88 was observed at the diagnostic level.

Hepatic malignancies.

The battle against malignancies of the liver is far from over, although tremendous strides have been made in the past decade, such as improved diagnostic capabilities, safe surgical resection, availability of safe nonsurgical ablative modalities, multimodality therapy, and aggressive approach to recurrent disease. Even after the best attempts at curative treatment, recurrence of primary and secondary malignancies of the liver continues to be the cause of demise for more than 70% of treated patients. The battle continues in the laboratories, where investigations are focused on delineating the pathophysiology of cancer on the molecular and genetic levels and mapping the patterns of cancer emergence and spread. The new millennium holds promise for formulating therapies that may improve disease-free survival for patients with malignancies of the liver.

Management of invasive squamous cell carcinoma of the bulbomembranous male urethra with co-ordinated chemo-radiotherapy and genital preservation.

OBJECTIVE: To determine the success of chemo-radiotherapy for squamous cell carcinoma (SCC) of the bulbar male urethra, an uncommon but aggressive cancer usually treated by radical deforming surgery. PATIENTS AND METHODS: Two men, aged 42 and 49 years, with locally advanced SCC of the proximal deep urethra were treated with a modified Nigro chemo-radiation protocol. The initial treatment was by suprapublic cystotomy urinary diversion followed by 45 Gy in 25 fractions over 5 weeks to the penis, perineum and regional lymphatics. Chemotherapy consisted of a single intravenous dose of mitomycin C (10 mg/m2) and an intravenous infusion of 5-fluorouracil (1 g/m2/day) for 96 h starting on the first day of radiation therapy and repeated 28 days later. RESULTS: Follow-up evaluation with urethral biopsies, retrograde urethrography, computed tomography of the pelvis and cysto-urethroscopy under anaesthesia showed no residual tumour in either patient but the development of a proximal urethral stricture at 1.5 and 4 years, respectively. CONCLUSION: This report presents the first evidence of a successful reduction of tumour stage with the local eradication of invasive SCC and penile preservation with no recurrence of the tumour or the need to excise the urethra.

Long-term brachial artery catheterization: ischemic complications.

The brachial artery is not used for long-term catheterization and routine hemodynamic monitoring because a high incidence of ischemic complications is anticipated. However, in a review of 157 patients who had 225 percutaneous transbrachial hepatic artery catheters placed for infusion of chemotherapeutic agents, catheters remained in situ from 1 day to 14 months (median 68 days). One hundred seventy-three catheters (77%) were removed electively and 52 catheters (23%) were removed because of complications. Diminution or loss of the radial pulses occurred on insertion of 88 catheters (39.1%) and 16 of these (8%) were removed after 24 hours because ischemic symptoms developed. Subsequently, 25 other catheters (11.1%) were removed because of complications such as paresthesia, eight (3.5%); brachial artery thrombosis, four (1.7%); microembolization, three (1.3%); claudication, two (0.8%); and pseudoaneurysm, one (0.4%). Seven catheters (3.1%) were removed because of a combination of pallor, diminished pulses, and muscle weakness. Hemorrhage from the arteriotomy site necessitated the removal of 11 other catheters (4.9%). Amputation, ischemic ulceration, major neuromuscular sequelae, and peripheral embolization to the head or lower limbs did not occur. This study suggests that long-term brachial artery catheterization is associated with a low incidence of permanent ischemic complications.

Prolonged and continuous percutaneous intra-arterial hepatic infusion chemotherapy in advanced metastatic liver adenocarcinoma from colorectal primary.

Sixty patients with advanced metastatic adenocarcinoma of the liver from a colorectal primary were treated by prolonged and continuous intra-arterial hepatic arterial infusion chemotherapy over a period of time from December 1969 through July 1976. A 10-day course of 5-FU was administered in the hospital, and patients were discharged receiving 5-FUDR by continuous arterial infusion through a chronometric infusion pump. Objective responses of 100% were obtained in 15% of patients, 50% response in 39% of patients, and 25% response in 21% of patients. The median survival from onset of treatment was 8.5 months, 6.9 months, and 7 months, respectively, for 100%, 50%, and 25% responders versus 3.6 months for nonresponders. Survivals from onset of treatment were generally less in those with no disease-free interval. No relationship of response to sex and age was found. Patients previously treated with 5-FU intravenously responded to intra-arterial chemotherapy; 13% had a 100% response, and 54% had a 50% response. No relationship of drug dose to response was observed. Drug toxicity was frequently systemic and mild to moderate. Numerous complications occurred due to the catheter, complete or partial thrombosis occurring in 18.6% and 20.8%, respectively, and 30% of patients had displacement of the catheter. The role of partial arterial occlusion in terms of response and survival may be significant. Future studies should involve comparison of direct surgical placement versus percutaneous placement of catheters.

Adrenalectomy-oophorectomy and combined chemotherapy for carcinoma of the breast with metastases.

Thirty-one patients with carcinoma of the breast with metastases were treated by adrenalectomy-oophorectomy and randomized either for combined chemotherapy, vincristine, fluorouracil, methotrexate and thiotepa, beginning within one week after operation and continuing for three months or no chemotherapy. Statistical analyses were Gehan's modification of the Wilcoxon test for censored data, chi-square tests and life table analysis. Pretreatment characteristics--menopausal status, age, disease-free interval, prior hormone treatment and sites of metastases--of both groups were similar. Objective response occurred in 73 per cent of 11 patients in the treatment. A group compared with 47 per cent of 15 patients in the treatment B group, p greater than 0.50. Median duration to relapse in responders was 16 months in the treatment A group and 15 months in the treatment B group, p greater than 0.50. Median survival was 19 months in the treatment A group and 20 months in the treatment B group, p greater than 0.50. Results were not significant, and inclusion of five patients with less than three months of treatment, did not alter the results. Hence, the group receiving early symptomatic treatment did not show an improved response rate, improved duration of remission or enhanced survival time from ablative treatment.

Intraaterial hepatic infusion and intravenous adriamycin for treatment of hepatocellular carcinoma: a clinical and pharmacology report.

Four patients received intraarterial (ia) hepatic infusion and 10 received intravenous (iv) adriamycin for hepatocellular carcinoma. Four of each group are evaluable. The remaining 6 patients died within 14 days of intravenous therapy and are, therefore, considered nonevaluable. Patients received 2 to 9 courses of adriamycin every 3 weeks. One half of each group of evaluable patients had partial responses (pr). The group had pr for 22.5 weeks (range 8 to 37). The iv group had pr 27.2 weeks (range: 16 to 38.5). Mean survival was 21 weeks for nonresponders, and 43 weeks for responders. Intraarterial infusion did not protect patients from adriamycin toxicity. Cardiac and liver toxicity were not seen, but marrow and gastrointestinal toxicity developed at 1.2 X 10(-7)M adriamycin serum level. Adriamycin disappearance curves after ia and iv therapy were similar for similar bilirubin levels, and prolonged with hyperbilirubinemia. Ascites fluid did not accumulate detectable adriamycin. Pharmacokinetics are described in this report.

Carcinomatous versus radiation-induced brachial plexus neuropathy in breast cancer.

A retrospective study was performed of 18 women in whom ipsilateral brachial plexus neuropathy developed after treatment for carcinoma of the breast. In the absence of metastatic tumor elsewhere, the only distinguishing feature between carcinomatous neuropathy and radiation-induced neuropathy was the symptom-free interval after mastectomy and radiation therapy. Women with an interval of less than a year have radiation-induced neuropathy. Brachial plexus exploration in difficult diagnostic situations will permit early treatment and avoid debilitating loss of function. Brachial plexus exploration for biopsy is safe and free of complications if performed carefully. Treatment of carcinomatous neuropathy is most likely to succeed if the tumor is hormonally sensitive, but radiotherapy may also be effective. Treatment of radiation-induced neuropathy remains largely ineffective.
