Evaluation of a face-to-face psychosocial screening intervention for cancer patients: acceptance and effects on quality of life.

OBJECTIVE: This study evaluated a psychosocial screening intervention that offers cancer patients counselling. The assumption underlying the intervention was that barriers are often present that hamper patients' awareness of and active request for psychosocial care. An active yet unobtrusive approach was hypothesized to improve accessibility to psychosocial services. METHODS: In a sequential cohort design, patients newly admitted to the oncology department of an academic hospital were assigned to a usual care group (n=50) or a screening group (n=79). A retrospective, medical records group (n=89) was also included. At baseline and 4 weeks following discharge, the usual care and screening groups completed mental health and quality of life questionnaires. RESULTS: Half the screening group actually wanted and received counselling. At follow-up, the screening group reported significantly less pain, better mental health and better physical and role functioning than the usual care group. CONCLUSION: The face-to-face screening intervention appears an effective means of identifying patients interested in obtaining formal psychosocial counselling, and may result in improvements in physical and mental health outcomes. PRACTICE IMPLICATIONS: This screening intervention may be particularly useful for hospitals that prefer a personal approach to psychosocial screening, but do not have sufficient resources to interview every new patient.

Minimally invasive parathyroidectomy without intraoperative localization.

Minimally invasive parathyroidectomy (MIP) is gaining popularity as an alternative to traditional bilateral exploration for patients with primary hyperparathyroidism. The success of MIP relies on the ability of preoperative and intraoperative localization studies to guide a directed exploration for resection of a diseased gland. We hypothesize that excellent results can be achieved with MIP when only technetium-99m sestamibi (MIBI) is used for localization. We conducted a prospective analysis of all patients presenting with a biochemical diagnosis of primary hyperparathyroidism between January 1997 and November 2000. Patients meeting inclusion criteria were given a choice of MIP and directed exploration versus traditional bilateral exploration. Fifty patients chose MIP. Three patients who chose MIP had a negative MIBI, which left 47 patients in the primary study group. The MIBI correctly identified a parathyroid adenoma in 42 patients (89.3%). In two other patients MIBI was inaccurate; however, directed exploration was successfully converted to a bilateral exploration. Overall 44 of 47 (93.6%) patients in the study group were rendered normocalcemic after the initial operation. Three patients experienced persistent hypercalcemia and subsequently underwent successful bilateral exploration. Including those patients choosing a bilateral exploration, a total of 59 positive MIBI scans were evaluated. There were 54 true positives (positive predictive value 91.5%), and if all patients had chosen a MIP 94.9 per cent would have been successfully treated at the initial operation. Mean operative time for MIP was 54.6 minutes, and in 32 patients (68.1%) MIP was performed with local anesthesia and sedation. Twenty-six patients (55.3%) were discharged the same day of the procedure. There were no significant complications in any group analyzed. We conclude that MIP can be successfully performed on the basis of a positive MIBI scan. The present study highlighting many of the advantages of MIP questions the necessity of additional adjuncts such as intraoperative parathyroid hormone measurement and gamma-probe localization.

Stereotactic breast biopsy: a study of first core samples.

Stereotactic core needle biopsy (SCNB) is a sensitive and specific indicator of breast pathology. Commonly the first biopsy core is taken from the center of the lesion in question. Multiple cores are then taken from points peripheral to the central core. The sensitivity and specificity of the central core to diagnose breast disease is unclear. We compared the pathology of the central core biopsy with that of the remaining cores in a prospective study to determine the sensitivity and specificity of the central core to diagnose breast disease. All patients undergoing SCNB for breast lesions in a single surgical office during a 7-month period were eligible for inclusion. One hundred thirty-three patients with first cores from 145 biopsy sites were included. The histologic diagnosis from 117 (81%) of the first cores from these 145 biopsy sites were representative of their respective samples as a whole. Seventy-seven (53%) of the first cores were in complete agreement with the final histologic diagnosis whereas 40 (28%) had minor differences with the histologic diagnosis that had little or no clinical significance. Twenty-eight (19%) central core samples did not agree with the final pathologic diagnosis. Seven of these 28 patients each had a final diagnosis of cancer missed by the central core biopsy. The first core sample had a sensitivity for cancer detection of 79 per cent and specificity 100 per cent. SCNB remains a sensitive and specific identifier of breast pathology. When mammographic evidence of calcifications was the primary indication for SCNB (n = 75) calcification was present in the central core in 51 (68%). In these 51 patients the central core biopsy was in agreement with the final histologic diagnosis in 46 (90%) specimens. Histologic review of the first core sample alone lends no increased benefits and in fact misrepresents the pathology present in a significant number of patients. When analyzed as an independent predictor of breast pathology the first core is a more sensitive indicator than subsequent individual cores, but the most accurate predictor of pathology is examination of the entire group of core samples. This study confirms the need for acquisition of multiple cores from each lesion in question.

Vacuum pack technique of temporary abdominal closure: a 7-year experience with 112 patients.

BACKGROUND: Temporary abdominal wound closure after celiotomy for trauma is often desirable. The ideal method of temporary closure should allow rapid closure, easy maintenance, and allow reexploration and wound repair with minimal tissue damage. Over the past 7 years, we have successfully used a vacuum closure system (the vacuum pack) for temporary management of the open abdomen. METHODS: Medical records of trauma patients undergoing exploratory celiotomy from April of 1992 to February of 1999 were reviewed. Demographic data as well as indications for open-abdominal management and complications of open-abdominal management were collected. RESULTS: Two hundred sixteen vacuum packs were performed in 112 trauma patients. Of the 216 vacuum packs placed, 2.8% were placed for increased intra-abdominal pressure, 5.3% for inability to achieve tension-free fascial closure, 20% for damage control, 55% for reexploration, and 16.7% for a combination of factors. Sixty-two patients (55.4%) went on to primary closure and 25 patients (22.3%) underwent polyglactin mesh repair of the defect followed by wound granulation and eventual skin grafting. Twenty-two patients (19.6%) died before abdominal closure was attempted. Five patients (4.5%) developed enterocutaneous fistulae. Five patients (4.5%) developed intra-abdominal abscesses. There were no eviscerations. Three patients (2.7%) required further explorations after abdominal closure. Overall mortality rate was 25.9%, none related to the vacuum pack. CONCLUSIONS: The vacuum pack is the temporary abdominal wound closure of choice in patients undergoing open abdominal management at our institution. Primary closure is achieved in the majority of patients with a low rate of complication. The technique is simple and easily mastered. Technical complications are rare and easily repaired.

The evaluation of subatmospheric pressure and hyperbaric oxygen in ischemic full-thickness wound healing.

We evaluated the efficacy of subatmospheric pressure and hyperbaric oxygen (HBO) as adjuncts in the treatment of hypoxic full-thickness wounds in a rabbit model. We hypothesized that subatmospheric pressure and HBO independently are effective in improving wound healing in the ischemic wound model and that when they are used in combination there is an increased positive effect on wound healing. Using a standard ischemic wound model four full-thickness wounds were created on each ear of 41 male New Zealand white rabbits (N = 82 ears). On each rabbit one ear was dressed with the vacuum-assisted closure (VAC) device and connected to suction; the other was dressed identically without the suction and suction tubing. Twenty rabbits were treated with HBO daily for 10 days at 2.0 atmospheres absolute for 90 minutes plus descent and ascent times. Necropsy on all rabbits was performed on postoperative day 10. Four ischemic wound treatment groups were evaluated: Group 1 (N = 21) VAC dressing alone; Group 2 (N = 20) VAC dressing plus HBO; Group 3 (N = 21) VAC dressing to suction alone; and Group 4 (N = 20) VAC dressing to suction and HBO. Using light microscopy a veterinary pathologist blinded to treatment groups quantified peak granulation tissue, granulation tissue gap, and epithelialization tissue gap. Data were analyzed by analysis of variance with significance indicated by P < 0.05. Statistical significance was found in a comparison of VAC dressing to suction and VAC dressing alone for peak granulation tissue and granulation tissue gap both with and without use of HBO. VAC device use appears to increase the rate of healing in a rabbit ischemic wound model. HBO therapy did not significantly affect the rate of healing in this model.

Traumatic fracture of the hyoid bone: three case presentations of cardiorespiratory compromise secondary to missed diagnosis.

Hyoid bone fractures secondary to blunt trauma other than strangulation are rare (ML Bagnoli et al., J Oral Maxillofac Surg 1988; 46: 326-8), accounting for only 0.002 per cent of all fractures. The world literature reports only 21 cases. Surgical intervention involves airway management, treatment of associated pharyngeal perforations, and management of painful symptomatology. The importance of hyoid fracture, however, rests not with the rarity of it, but with the lethal potential of missed diagnosis. We submit three cases with varying presentations and management strategies. All three of our cases incurred injury by blunt trauma to the anterior neck. Two patients required emergent surgical airway after unsuccessful attempts at endotracheal intubation. One patient presented without respiratory distress and was managed conservatively. After fracture, the occult compressive forces of hematoma formation and soft tissue swelling may compromise airway patency. It is our clinical observation that hypoxia develops rapidly and without warning, leading to cardiorespiratory collapse. With endotracheal intubation prohibited by obstruction, a surgical airway must be established and maintained. Recognition of subtle clinical and physical findings are critical to the diagnosis of laryngotracheal complex injuries and may be life-saving in many instances. To ensure a positive outcome, a strong degree of suspicion based on mechanism of injury is mandated.

Craniometaphyseal dysplasia. Report of a case.

Craniometaphyseal dysplasia, often referred to as Pyle's disease, is a hereditary disease involving the expansion of the metaphyses of the long bones, giving the appearance of an Erlenmeyer flask. There is diffuse hyperostosis of the entire cranial vault, along with absence or decreased development of the paranasal sinuses. In the case presented here the mouth demonstrated an abnormality wide maxilla with a slight palatal vault. Genetically, this appeared to be a dmoninant form of dysplasia.
