Lack of awareness of oesophageal carcinoma among the public in Ireland

BACKGROUND

Oesophageal cancer is advanced in the majority at presentation and its symptoms are usually present for many months suggesting poor awareness of its symptoms. Few studies have examined awareness of oesophageal cancer amongst the public.

AIMS

This study aimed to identify the level of awareness among the general public of oesophageal cancer, of its symptoms, of its awareness campaigns and to compare it with other common cancers.

METHODS

Face-to-face interviews were conducted with 279 members of the public. People were asked about their awareness of a range of cancers, and their knowledge of cancer symptoms and cancer awareness campaigns.

RESULTS

Awareness of oesophageal cancer was low and knowledge of its symptoms was even lower. Despite the efforts of awareness campaigns, knowledge of these campaigns was poor amongst the public.

CONCLUSION

Awareness of oesophageal cancer and its symptoms is low amongst the public. This needs to be addressed if disease is to be detected at an earlier and curable stage.

Attitudes of Irish dental, dental hygiene and dental nursing students and newly qualified practitioners to tobacco use cessation: a national survey

BACKGROUND

Ireland has some of the strictest smoking regulations in the world. Little is known of the attitudes of student Irish dental healthcare workers towards tobacco control and tobacco use cessation. This study aimed at determining the knowledge and attitudes of these students towards the deleterious effects of tobacco in the mouth and towards tobacco use cessation in dental practice.

METHOD

A questionnaire survey was distributed to 654 students (including newly qualified) on dentistry, dental hygiene and dental nursing programmes in Irish dental schools. Information sought included college, course, year of study, sex, age, nationality, smoking status, knowledge of effects of tobacco in the mouth and attitudes towards tobacco use cessation in dental practice and towards the Irish smoking bans.

MAIN FINDINGS

There was a 90% response rate. In all, 12% of dental students, 25% of dental hygiene students and 31% of dental nursing students were current smokers. Newly qualified dental hygienists were as knowledgeable about tobacco effects in the mouth as newly qualified dentists. Overall, the majority in each student category believed that all three groups could be effective tobacco counsellors and should provide tobacco use cessation counselling to patients, although less than half of evening course dental nursing students felt that dental nurses could be effective counsellors or should provide counselling. There was overwhelming support for the Irish smoking ban. Only a minority of dental students and dental nursing students had received instruction in tobacco use cessation counselling.

CONCLUSIONS

There are strong positive attitudes to tobacco use cessation counselling in dental practice among these young dental healthcare students. This is true even amongst those who have not received specific instruction in tobacco use cessation counselling.

Office surgery incidents: what seven years of Florida data show us

BACKGROUND

In the wake of increased media attention focusing on human error in medicine, numerous state medical boards and legislatures have drafted, and are continuing to draft, regulations aimed at protecting patients undergoing procedures in the office setting. These regulations will have a considerable impact on patient access to medically necessary procedures, and any regulations should be based on good data. This report summarizes 7 years of prospective data from the state of Florida, the best data available on office surgery incidents.

OBJECTIVE

The objective was to determine the nature and incidence of hospital transfers and deaths resulting from office procedures.

METHODS

This study is a compilation of mandatory reporting by Florida physicians to a central agency of all in-office adverse incidents resulting in death, serious injury, or hospital transfer in the State of Florida from March 2000 to March 2007. Telephone and internet follow-up was conducted to determine reporting physician board certification, hospital privileges, and office accreditation.

RESULTS

In 7 years there were 31 deaths and 143 procedure-related complications and hospital transfers. Liposuction and liposuction with abdominoplasty or another cosmetic procedure resulted in 24 complications and 8 deaths. Of the offices reporting adverse incidents, 38.5% were accredited by an independent accrediting agency, 92.5% of the physicians were board-certified, and 96.6% had hospital privileges. A total of 58% (18/31) of the deaths and 61% (87/143) of the complications were associated with nonmedically necessary (cosmetic) procedures. A total of 78% (14/18) of these deaths were in ASA Class 1 patients. Plastic surgeons were responsible for 48% of all deaths (83% of cosmetic surgery deaths) and for 52% of all hospital transfers (83% of cosmetic surgery complications and hospital transfers).

CONCLUSION

Plastic surgeons were responsible for an inordinate number of deaths and hospital transfers. Requiring physician board certification and physician hospital privileges would not seem to increase safety, because most physicians already have these credentials, and physicians without these credentials were not responsible for a disproportionate share of incidents. These data do not show an emergent hazard to patients from medically necessary office surgery. Liposuction under general anesthesia deserves continued scrutiny because deaths due to this procedure continue to occur and this procedure can be performed with dilute local anesthesia, with which no deaths were reported. Mandatory reporting of office incidents should be strongly supported, as well as reporting of incidents that occur after surgery in the hospital outpatient department and ambulatory surgery center. These data should be available for analysis after protecting patient confidentiality. A national debate needs to occur to determine how many deaths and injuries are acceptable from cosmetic procedures performed under general and intravenous anesthesia.

Routine PET and PET-CT scans in melanoma patients with positive sentinel node biopsy is of limited benefit

8582

Background: Positron emission tomography (PET) scanning is increasingly used for the staging and management of malignant melanoma. The role of PET as a routine procedure in patients with positive sentinel node biopsy (SNB) is not yet established. We report in the series with longest follow up outcomes of PET scans performed in patients with subclinical lymph node disease. Methods: Case notes of 29 sequential patients with melanoma of Breslow thickness greater than 1mm who had PET scans within 130 days after a positive SNB were reviewed. Four patients had a PET after the lymph node dissection (LND). Results: 2 patients (6%) had a positive PET scan neither of which was melanoma related. The first patient had a thyroid tumour confirmed with fine needle aspiration biopsy and the second patient had increased uptake in the chest wall which on verification with bone scan proved to be old trauma. 28 patients (96%) had a LND and this was positive in 5 cases (17%). With a median follow up of 23 months 21 patients remained disease free. Out of the 8 patients (27%) who presented with recurrence 2 (25%) were successfully treated with further surgery and remained in remission, 4 (50%) died, 1 (12.5%) was lost from follow-up and 1 (12.5%) is followed up in another hospital. In none of the 29 cases did the early PET scan after a positive SNB alter subsequent melanoma management. Conclusions: The role of PET scanning soon after a positive sentinel node biopsy appears to be of uncertain benefit. It is questionable whether any imaging is beneficial at this stage. The results of this review suggest that PET scanning might not be indicated for this group of patients but larger prospective studies are required to confirm this.

The effect of thermal preconditioning of the limb on flexor tendon healing

Thermal preconditioning reduces inflammation by inducing cytoprotective heat shock proteins. We evaluated the role of limb thermal preconditioning in a rabbit model of flexor tendon repair. The treatment groups underwent limb preconditioning by elevating the limb temperature to 41.5 degrees C for 20 minutes. The animals were sacrificed three and six weeks after flexor tendon repair. Heat shock protein72 expression of the treated limb was measured at 18 hours. Macroscopic analysis demonstrated a significant decrease in adhesion formation in the three week treatment group. The inflammatory infiltrate was significantly reduced for both treatment groups. The difference in ultimate tensile strength was not significant. We conclude that thermal preconditioning of the limb before flexor tendon repair decreases inflammation and adhesion formation in a rabbit model and has the potential to improve clinical outcome of flexor tendon surgery.

Sonic hedgehog in the pharyngeal endoderm controls arch pattern via regulation of Fgf8 in head ectoderm

Fgf8 signalling is known to play an important role during patterning of the first pharyngeal arch, setting up the oral region of the head and then defining the rostral and proximal domains of the arch. The mechanisms that regulate the restricted expression of Fgf8 in the ectoderm of the developing first arch, however, are not well understood. It has become apparent that pharyngeal endoderm plays an important role in regulating craniofacial morphogenesis. Endoderm ablation in the developing chick embryo results in a loss of Fgf8 expression in presumptive first pharyngeal arch ectoderm. Shh is locally expressed in pharyngeal endoderm, adjacent to the Fgf8-expressing ectoderm, and is thus a candidate signal regulating ectodermal Fgf8 expression. We show that in cultured explants of presumptive first pharyngeal arch, loss of Shh signalling results in loss of Fgf8 expression, both at early stages before formation of the first arch, and during arch formation. Moreover, following removal of the endoderm, Shh protein can replace this tissue and restore Fgf8 expression. Overexpression of Shh in the non-oral ectoderm leads to an expansion of Fgf8, affecting the rostral-caudal axis of the developing first arch, and resulting in the formation of ectopic cartilage. Shh from the pharyngeal endoderm thus regulates Fgf8 in the ectoderm and the role of the endoderm in pharyngeal arch patterning may thus be indirectly mediated by the ectoderm.

Practice patterns in flexor tendon repair

BACKGROUND

There is a considerable volume of literature describing new and supposedly superior methods of flexor tendon repair.

AIM

The purpose of this study was to assess the flexor tendon techniques currently used in the Republic of Ireland.

METHODS

A postal survey was conducted of all consultant plastic surgeons and consultant orthopaedic surgeons who were members of the Irish Hand Surgery Society.

RESULTS

The response rate was 90% (27/30). A simple running peripheral suture was used by 73% (P = 0.03) and the Kessler was the core suture of choice for 68% (P = 0.06). A significant number of respondents use non-absorbable suture materials for core (P = 0.0028) and peripheral suture (P < 0.0001). Seventy-seven percent sutured the flexor sheath where possible (P = 0.009).

CONCLUSIONS

Notwithstanding the proposed advantages of newer techniques, it is evident from this study that the two-stranded Kessler core and simple running peripheral suture remains the most popular flexor tendon repair, with sheath closure preferred by the majority of respondents.

Routine staging radiology is not needed for all breast cancer patients

10648

Background: Early stage breast carcinoma is unlikely to have undergone metastatic spread at the time of presentation. The utility of routine staging liver ultrasound (LUS) and bone scan (BS) in early stage disease is unclear. We postulate that early stage breast cancer patients do not need routine radiological staging. Methods: We studied 200 patients with a diagnosis of invasive breast carcinoma. 100 with symptomatic breast cancer (SBC) and 100 with screen detected (SD). Patients’ histology, tumour markers (CEA, CA 15.3), hormone receptor status, CXR, LUS and BS results were reviewed. Results: All patients underwent curative surgery for early stage invasive breast cancer. 3 patients had liver metastases diagnosed by LUS. Two of these patients were from the SBC and one from SD (grade ≥2, mean tumour size 2.2 cm). 4 patients had bony metastases diagnosed by BS. Three of these were from the SBC and one from SD (grade ≥2, mean tumour size 3.2 cm.). No patients with low-grade T1 tumours had signs of metastasis on BS or US. Conclusions: The incidence of metastatic disease is very low in newly diagnosed early stage breast carcinoma. Our results suggest that patients with low-grade T1 tumours do not need staging BS or US.

One-stage Fowler-Stephens orchidopexy for impalpable undescended testis

BACKGROUND

The Fowler-Stephens orchidopexy (FSO) is a well-described treatment for high maldescended testes where the limiting factor for successful placement in the scrotum is short testicular vessels. The operation involves division of these vessels. The testicular blood supply is then dependent on collaterals from the vasal artery.

AIMS

To assess the long-term outcome of patients who underwent this procedure in our institution.

METHODS

The medical records of 20 patients who underwent 22 FSO from 1978 to 1999 by one urologist (HB) were reviewed. Outcome was assessed in terms of testicular position and size.

RESULTS

Age at operation ranged from 2 to 14 years (mean 5.8 years). All patients had a one-stage FSO and in two of them the procedure was bilateral. In five patients, FSO was preceded by a diagnostic laparoscopy. Mean follow up was 22 months (range 0-121 months). Overall, results were considered good in 18 of 22 testes (82%).

CONCLUSION

Our results for the one-stage FSO are comparable with other procedures for the management of high maldescended testis.

Percutaneous endoscopic gastrostomy: 5 years of clinical experience on 238 patients

Since Percutaneous Endoscopic Gastrostomy (PEG) feeding was introduced, 20 years ago it has been increasingly utilised in medical practice. The aim of this study was to assess the current indications and complications associated with PEG feeding. This study was a retrospective review of hospital charts dealing with PEG placement over a period of five years. The indications for insertion were, central nervous disease 76% (n = 156), other benign disease 14% (n = 28) and malignancy 10% (n = 21). Cerebrovascular accidents (CVA) alone accounted for 47% (n = 97). Ninety seven (50%) patients had minor complications, which included 43 (22%) wound infections. There were 6 (3%) major complications, including peritonitis, perforation and aspiration pneumonia. There were four deaths (2%) related to PEG placement, of whom three developed aspiration pneumonia and one peritonitis. The overall 30 day mortality rate was 16%. There was a 75% increase in the use of PEG placement over the five year period. PEG placements were associated with a 53% morbidity and a 2% procedure related mortality. There was a 16% 30 day mortality following PEG placement suggesting that the selection criteria for PEG placement may need to be refined further.

Parathyroid localisation--current practice

In patients with primary hyperparathyroidism, neck exploration by an experienced parathyroid surgeon is curative in excess of 95% of cases. Considerable efforts have been devoted to improving parathyroid imaging. New radionucleotide agents and scanning procedures have markedly improved the success rate of localization studies with subsequent development of minimally invasive surgical techniques. In this article we review the different localization techniques and their current role in parathyroid surgery for primary hyperparathyroidism

Pregnancy-associated breast cancer

Twelve premenopausal women diagnosed with pregnancy-associated breast cancer between May 1985 and October 1999 were reviewed. Three patients were diagnosed in the first trimester of pregnancy, five in the second trimester, and three during the third trimester. There was one patient who was five weeks postpartum. At the time of diagnosis nine patients had lymph node involvement and two of these had metastatic disease. Four patients received primary chemotherapy. The remainder had surgery. Five patients died, two had metastatic disease at time of diagnosis, median survival was 31 months. There were three fetal deaths, one termination and two during primary chemotherapy. The diagnosis of breast cancer during pregnancy is difficult. Presentation is usually at an advanced stage. Surgery can be safely performed during pregnancy and adjuvant chemotherapy should not be postponed until after delivery.

Fostering health in the foster care maze

The fastest growing population of children in foster care today is quite young, and many of these children have significant health care needs. The General Accounting Office (GAO) reported that children in foster care "are among the most vulnerable individuals in the welfare population" (GAO, 1995, p. 1). Poverty, increased homelessness, substance abuse, and a rise in the incidence of persons with HIV all contribute to the problems faced by these children. The Caring Communities for Children in Foster Care Project, funded by the Maternal Child Health Bureau Integrated Services Medical Home Initiative with the American Academy of Pediatrics (AAP), investigated the availability of comprehensive health care services for children in foster care. The AAP recommends that pediatricians serve as the primary health care provider for children in foster care and also as consultants to child welfare agencies. Pediatric nurses play a crucial role in providing health care services to children in foster care. With an increased understanding of the potential physical and mental health care needs of children in foster care and the important role of foster parents, pediatric nurses can increase the likelihood of positive health outcomes for children in foster care.

Extended scope of nursing practice: a multicentre randomised controlled trial of appropriately trained nurses and pre-registration house officers in pre-operative assessment in elective general surgery

OBJECTIVES

(1) To determine whether pre-operative assessment carried out by an appropriately trained nurse (ATN) is equivalent in quality to that carried out by a pre-registration house officer (PRHO). (2) To assess whether pre-assessments carried out by ATNs and PRHOs are equivalent in terms of cost. (3) To determine whether assessments carried out by ATNs are acceptable to patients. (4) To investigate the quality of communication between senior medical staff and ATNs.

DESIGN

The study design was principally a prospective randomised equivalence trial but was accompanied by additional qualitative assessment of patient and staff perceptions, and an economic evaluation.

SETTING

The study was carried out at four NHS hospitals, three of which were teaching hospitals, in three NHS Trusts in Southampton, Sheffield and Doncaster.

SUBJECTS

All patients attending at one site for assessment prior to general anaesthetic for elective general, vascular, urological or breast surgery were potentially included in the study. Of 1907 patients who were randomised, 1874 completed the study with a full evaluation.

INTERVENTIONS

The intervention consisted of a pre-operative assessment carried out by either an ATN or a PRHO. Of the patients who completed the study with a full evaluation, 926 patients were randomised to the PRHO arm of the trial and 948 to the ATN arm. Three ATNs took part in the study, one from each centre, together with a total of 87 PRHOs.

MAIN OUTCOME MEASURES

Immediately following the initial assessment of a patient by a PRHO or an ATN, one of a number of clinical research fellows, all specialist registrars in anaesthetics, repeated the assessment and recorded it on a study form, together with a list of investigations required. The clinical research fellow then evaluated the competency of the initial assessor by comparing the quality of their assessment with their own. Any deficiencies in ordering of investigations and referral to other specialities were met in order to maximise patient care. Three areas of ATN and PRHO performance were judged separately, history taking, examination and ordering of tests, and each was graded into one of four categories, the most important of which was under-assessment, which would possibly have affected peri-operative management. In the case of ordering of tests, it was possible to have both over- and under-assessed a patient on different tests.

RESULTS

The pre-operative assessments carried out by the ATNs were essentially equivalent to those performed by the PRHOs in terms of under-assessment that might possibly have affected peri-operative management, although there was variation between the ATNs in terms of the quality of history taking. This may be related to the low number of patients seen at one study site. PRHOs ordered significantly more unnecessary tests than the ATNs. The substitution of ATNs for PRHOs was calculated to be cost neutral. The results of the qualitative assessment showed that the use of ATNs for pre-operative assessment was acceptable to patients; however, there was no evidence that communication between senior medical staff and those carrying out pre-operative assessments was improved by their introduction.

CONCLUSIONS

This study demonstrated no reason to inhibit the development of fully nurse-led pre-operative assessment, provided that the nurses are appropriately trained and maintain sufficient workload to retain skills. CONCLUSIONS--IMPLICATIONS FOR THE HEALTH SERVICE: ATNs provide an acceptable and efficient alternative to PRHOs for the purposes of routine pre-operative assessment. Consideration will have to be given, however, to the positions of these nurses within the surgical team, and also to their career structure. CONCLUSIONS--RECOMMENDATIONS FOR FUTURE RESEARCH: Further research is needed in the following areas: (1) the extent and type of training needed for nurses undertaking the pre-operative assessment role; (2) the use, costs and benefits of routine pre-operative testing.

Comparison of Positron Emission Tomography Scanning and Sentinel Node Biopsy in the Detection of Micrometastases of Primary Cutaneous Malignant Melanoma

PURPOSE: Sentinel node biopsy (SNB) is a surgical technique for detecting micrometastatic disease in the regional draining nodes. 2-fluorine-18-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) scanning is an imaging technique that can detect clinically undetectable metastases. This prospective study was undertaken to compare the sensitivity of FDG-PET scanning with SNB in the detection of micromatastatic malignant melanoma.

PATIENTS AND METHODS: Fifty consecutive patients (23 women, 27 men; mean age, 53 years) with primary melanoma >1 mm thick or lymphatic invasion were recruited (mean, 2.41 mm). Primary lesions had been narrowly excised (<1 cm). Patients underwent PET scanning followed by SNB, using a dual technique. Preoperative lymphoscintigraphy was used to identify the draining basin. Lymph nodes were examined histologically and immunostained for S100 and HMB 45.

RESULTS: The sentinel node (SN) was identified in all patients. Fourteen patients (28%) had positive SNBs, including eight patients with melanoma <1.5 mm thick. In none of these 14 patients did PET scans identify metastatic disease in the SN or draining basin. In seven patients, the PET scans were positive in other locations, and in four cases, this was suspicious of metastatic disease. However, no patient has developed recurrent melanoma (mean follow-up, 15 months). All patients with positive SNBs underwent therapeutic lymph node dissection. Further lymph node involvement was found in two patients (primary lesions, 1.3 mm and 3.5 mm thick).

CONCLUSION: This study demonstrates the limitations of FDG-PET scanning in staging patients with primary melanoma. SNB is the only reliable method for identifying micrometastatic disease in the regional draining node.
