Boron clusters as breast cancer therapeutics. J Inorg Biochem 2021; 218:111412. [PMID: 33773323 DOI: 10.1016/j.jinorgbio.2021.111412] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 02/21/2021] [Accepted: 02/24/2021] [Indexed: 12/16/2022]
Abstract
Since the foundation of small molecule-based therapeutics over 100 years ago, their design has been dominated by organic based components. This has also been apparent in anti-cancer therapeutics in a broad range of strategies; from the older DNA chelating drugs, to the more recent molecular-targeted therapies. The main challenges facing current treatments; multidrug resistance and low therapeutic index, can potentially be alleviated by the incorporation of boron clusters. While retaining the versatility of their organic counterparts, these compounds offer a unique set of molecular interactions, which are a useful tool in targeted therapies and can improve many organic formulations with their incorporation. This review will discuss the potential of boron clusters in medicine while focusing on their activity in the breast cancer setting.

"There's always something else": Patient perspectives on improving the implementation of obesity guidelines in general practice. Obes Res Clin Pract 2020; 14:437-442. [PMID: 32962956 DOI: 10.1016/j.orcp.2020.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 09/08/2020] [Accepted: 09/11/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVES The prevalence of obesity in Australia is rising. National guidelines for the management of overweight and obesity exist but our previous work demonstrates poor implementation of key elements in general practice. The aim of this study was to describe patient perspectives on the implementation of obesity guidelines in general practice. METHODS Qualitative study of 40 people living with obesity (PwO) who were recruited through general practices in Melbourne, Australia. PwO had a recorded BMI in the overweight range or above (>25), had attended a consultation in the last 6 months and had a diagnosis of at least one of the following: diabetes, kidney disease, hyperlipidemia, hypertension, or cardiovascular disease. Semi-structured telephone interviews were conducted with patients. Interviews were audio-recorded, transcribed verbatim and analysed thematically. RESULTS While a strong general practitioner (GP)-patient relationship enabled conversation to occur about weight management there was uncertainty as to whether patients or GPs should broach the topic of weight. Patients described complacency regarding their weight and often being unprepared to take up GP advice. Other health issues were felt to take precedence, and patients described inconsistent provision of information and resources to assist them in tackling their weight problems. CONCLUSIONS It is imperative to take into account patient perspectives on obesity management in general practice in order to improve health outcomes. This study provides valuable insights into how PwO can be better managed. Interventions should also include strategies to help patients maintain motivation in making lifestyle changes to support healthy weight loss.

Sigmoid Perforation Secondary to Accidental Ingestion of a Chicken Bone. IRISH MEDICAL JOURNAL 2020; 113:12. [PMID: 32298562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
Presentation We describe an unusual presentation of sigmoid colon perforation secondary to an ingested chicken bone. Diagnosis The patient presented with a 4 day history of abdominal pain and distension. On examination there were signs of peritonism. Inflammatory markers were raised. Computed tomography revealed a linear density projecting through the wall of the colon. Treatment The patient underwent emergency laparotomy and a Hartmann's procedure. A chicken bone was found to be the causative foreign object. Conclusion Foreign body ingestion is an uncommon cause of sigmoid perforation which may mimic more common surgical presentations such as diverticulitis.

Abstract
Atrial fibrillation (AF) is the most common irregular heartbeat among the world's population and is a major contributor to cardiogenic embolisms and acute ischemic stroke (AIS). However, the role AF flow plays in the trajectory paths of cardiogenic emboli has not been experimentally investigated. A physiological simulation system was designed to analyze the trajectory patterns of bovine embolus analogs (EAs) (n = 720) through four patient-specific models, under three flow conditions: steady flow, normal pulsatile flow, and AF pulsatile flow. It was seen that EA trajectory paths were proportional to the percentage flowrate split of 25–31% along the branching vessels. Overall, AF flow conditions increased trajectories through the left- (LCCA) and right (RCCA)-common carotid artery by 25% with respect to normal pulsatile flow. There was no statistical difference in the distribution of clot trajectories when the clot was released from the right, left, or anterior positions. Significantly, more EAs traveled through the brachiocephalic trunk (BCT) than through the LCCA or the left subclavian. Yet of the EAs that traveled through the common carotid arteries, there was a greater affiliation toward the LCCA compared to the RCCA (p < 0.05).

"90% of the time, it's not just weight": General practitioner and practice staff perspectives regarding the barriers and enablers to obesity guideline implementation. Obes Res Clin Pract 2019; 13:398-403. [PMID: 31109793 DOI: 10.1016/j.orcp.2019.04.001] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 03/25/2019] [Accepted: 04/05/2019] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To identify the views of GPs and general practice staff regarding barriers and enablers to implementation of obesity guideline recommendations in general practice. METHODS Twenty general practitioners (GPs) and 18 practice staff from inner-eastern Melbourne, Australia, participated in semi-structured telephone interviews. The interview schedule was informed by the Theoretical Domains Framework (TDF). Interviews were audio-recorded, transcribed verbatim and underwent thematic analysis. RESULTS Participants lacked familiarity with and knowledge of the NHMRC obesity guidelines. Barriers and enablers were predominantly related to five theoretical domains: (1) environmental context and resources, (2) knowledge, (3) emotion, (4) beliefs about consequences, and (5) motivation and goals. Time pressures in consultations, costs for the patient, reluctance to add to patient burden particularly in those with comorbidities such as mental health issues, lack of awareness about services to refer patients to and GPs' fear of embarrassing patients and losing them were significant barriers. Enablers included having a strong doctor-patient relationship and a sense of responsibility to the patient to address weight. CONCLUSIONS Obesity guidelines and policy makers need to better engage with issues of multimorbidity, socioeconomic disadvantage and workforce issues if recommendations are to be widely adopted in general practice. Tasksharing, teamwork and technology are potential solutions to some of the barriers. Patient perspectives and approaches to being able to overcome stigma and legitimise obesity management in primary care consultations could also assist.

Abstract
BACKGROUND Adolescents living with chronic conditions often portray themselves as "healthy" online, yet use the Internet as one of their top sources of health information and social communication. There is a need to develop online support programs specific to adolescents with chronic conditions in order to provide a private space to discuss concerns. This paper endeavors to increase our understanding of the online support needs and wants of these adolescents and their interest in and preferences for an online support program. METHODS A qualitative descriptive study using semistructured interviews was completed. Stratified purposive sampling was utilized to ensure a representative sample based on age and diagnosis. English speaking adolescents (aged 12-18 years) diagnosed with a chronic condition were recruited from clinic and inpatient areas across 3 paediatric hospitals in Canada. RESULTS Thirty-three participants aged 15.3 ± 1.8 years (64% female) completed the study. The main topics identified were (a) the purpose of current online activity, (b) the benefits and challenges of existing online supports, and (c) a description of ideal online resources. The purpose of online activity was social networking, information, online gaming, and social support. When accessing health information online, participants prioritized websites that were easy to access and understand despite the trustworthiness of the site. The reported benefits and challenges varied across participants with many areas perceived as both a benefit and a challenge. The majority of participants were interested in participating in an online support program that included both accurate disease-related information and a community of other adolescents to provide social support. CONCLUSIONS Adolescents with chronic conditions are interested in online support that encompasses health information and social support that is flexible and easy to navigate. Findings can be used to develop or adapt existing online support programs for adolescents with chronic conditions to help increase engagement and utilization.

Abstract
A microsporidian species with 98.3-98.4% nucleotide identity to Tetramicra brevifilum (Journal of Fish Diseases, 3, 1980, 495) was diagnosed in lumpfish (Cyclopterus lumpus, L.) broodstock held at a breeding and rearing facility in western Ireland. The fish were wild-caught from the west coast of Ireland, and the first case was diagnosed one year after capture. Clinical signs included severe bloating, lethargy, exophthalmos, anorexia, white patches on the cornea and externally visible parasitic cysts on skin and fins. Necropsy revealed severe ascites, white nodules and vacuoles in all the internal organs and partial liquefaction of the skeletal muscle. On histological examination, microsporidian xenomas were observed in all internal organs, the skin, skeletal muscle, gills and the eyes. The microsporidian species was identified by molecular analysis and transmission electron microscopy. This is the first record of T. brevifilum infecting lumpfish, and the disease is considered to be of potential significance to the rising aquaculture industry of this species.

Abstract
UNLABELLED Cutaneous skeletal hypophosphatemia syndrome (CSHS), caused by somatic RAS mutations, features excess fibroblast growth factor-23 (FGF23) and skeletal dysplasia. Records from 56 individuals were reviewed and demonstrated fractures, scoliosis, and non-congenital hypophosphatemia that in some cases were resolved. Phosphate and calcitriol, but not skin lesion removal, were effective at controlling hypophosphatemia. No skeletal malignancies were found. PURPOSE CSHS is a disorder defined by the association of epidermal and/or melanocytic nevi, a mosaic skeletal dysplasia, and an FGF23-mediated hypophosphatemia. To date, somatic RAS mutations have been identified in all patients whose affected tissue has undergone DNA sequencing. However, the clinical spectrum and treatment are poorly defined in CSHS. The purpose of this study is to determine the spectrum of the phenotype, natural history of the disease, and response to treatment of hypophosphatemia. METHODS Five CSHS subjects underwent prospective data collection at clinical research centers. A review of the literature identified 45 reports that included a total of 51 additional patients, in whom the findings were compatible with CSHS. Data on nevi subtypes, bone histology, mineral and skeletal disorders, abnormalities in other tissues, and response to treatment of hypophosphatemia were analyzed. RESULTS Fractures, limb deformities, and scoliosis affected most CSHS subjects. Hypophosphatemia was not present at birth. Histology revealed severe osteomalacia but no other abnormalities. Skeletal dysplasia was reported in all anatomical compartments, though less frequently in the spine; there was no clear correlation between the location of nevi and the skeletal lesions. Phosphate and calcitriol supplementation was the most effective therapy for rickets. Convincing data that nevi removal improved blood phosphate levels was lacking. An age-dependent improvement in mineral abnormalities was observed. A spectrum of extra-osseous/extra-cutaneous manifestations that included both benign and malignant neoplasms was present in many subjects, though osteosarcoma remains unreported. CONCLUSION An understanding of the spectrum, natural history, and efficacy of treatment of hypophosphatemia in CSHS may improve the care of these patients.

Abstract
Subclinical hypothyroidism (SCH) is defined as a raised serum thyroid stimulating hormone level with normal thyroxine. Despite a prevalence of up to 9% of the adult population there is widespread uncertainty on how to manage it. The aim of this study was to assess how older adults with SCH are managed in primary care. A retrospective case-note review was carried out on patients attending Mallow Primary Healthcare Centre. This study identified patients 65 years and over meeting the criteria for SCH in one year. The prevalence of SCH in this study was calculated as 2.9%. 22.2% of patients were treated with thyroxine. 6.1% of untreated patients progressed to clinical hypothyroidism within the study period while 18.2% spontaneously reverted to normal TSH levels.

Abstract
OBJECTIVE Phyllodes tumours (PTs) are rare neoplasms accounting for <1% of breast lesions. With increased breast awareness and screening programmes, smaller PTs are being detected. The purpose of this study was to determine the clinical, radiological and pathological presentation of PTs and to evaluate the role of imaging follow-up, for which there are no specific guidelines. METHODS A retrospective study of all patients diagnosed with PT in a symptomatic unit between January 2006 and March 2013 was carried out. Patients were identified using breast care and electronic patient record databases. RESULTS 53 patients with 54 lesions were diagnosed as having a PT. The median age was 27.5, 35.0 and 38.5 years for benign, borderline and malignant PT, respectively. Borderline and malignant PTs were larger than benign PTs, with mean sizes of 33 and 42 mm compared with 29 mm. 38% of PTs were labelled by the reporting radiologist as fibroadenomas, including two borderline PTs and one malignant PT. In 24% of cases, the radiologist raised the possibility of PT in the report. 17 patients (40%) developed a new fibroepithelial breast lesion during follow-up of which 4 were recurrent PTs. CONCLUSION Despite adequate surgical management, the development of further fibroepithelial lesions in the ipsilateral breast is common. 3-year clinical surveillance, with the addition of 6-monthly ultrasound is advised for females with initial borderline or malignant PT histology. ADVANCES IN KNOWLEDGE We propose a follow-up protocol with ultrasound based on the grade of the PT diagnosed for 3 years to detect recurrence.

Abstract
Elm yellows (EY) is a lethal disease of American (Ulmus americana L.) and other elm species (1). On the Pennsylvania State University campus, EY, together with Dutch elm disease, has killed 82 of about 400 mature elms since 2007, the year of first EY detection. Candidatus Phytoplasma ulmi, associated with EY, has been reported to be transmitted by the whitebanded elm leafhopper Scaphoideus luteolus Van Duzee, the meadow spittlebug Philaenus spumarius L., and the leafhopper Allygus atomarius Fabricius (1) in North America, but correlation of these insects with EY in the eastern United States has not been reported. Three Cicadellidae collections using sweep nets and aspirators were performed from July to September 2012 on branches of an EY infected red elm (U. rubra Muh; 40°48.408'N, 77°52.208'W) and on vegetation within a 0.5 km radius. The red elm is in close proximity to trees, shrubs, and a managed meadow and has repeatedly tested positive for EY since 2007. During each collection, about 200 cicadellids were captured in BioQuip No-See-Um catch bags with cups, and the bags were hung around the red elm branches, forcing the insects to feed on the infected tree for 24 h. Insects were transferred to BugDorm rearing tents containing wild grasses, elm seedlings, cowpeas, celery, carrots, and basil, all grown from seed, and were kept for 3 weeks in a controlled environment chamber at 28°C and 70% humidity with a 16-h photoperiod. Insects easily recognized in the same species or individual insects of uncertain identity were then isolated for about 1 week in cages each containing one 6-month-old healthy American elm seedling (grown from seed in growth chamber). Up to 10 morphospecies were found in each collection, with 1 to 20 individuals per morphospecies. The total number of unique morphospecies used in the three transmission trials and later identified as different species was 8. Dead insects collected daily were stored in 80% ethanol and later identified to genus or species level. About 70% insect mortality was recorded, but about 60 individuals from each collection survived the change of diet and environment. After 3 months, individual elm seedlings were tested by RT-PCR (3) for the presence of phytoplasmas using universal primers fU5/rU3 (2). PCR products were visualized on 1.5% agarose gel, and if DNA was amplified, it was cloned and sequenced. Three of 30 seedlings tested positive for phytoplasmas and sequencing of the cloned products (24 clones were sequenced per transformation, per each of the three positive seedlings) confirmed that only Ca. P. ulmi was present in the 3 infected seedlings but not in the remaining 27 or in 46 unexposed control seedlings. The 3 seedlings were each exposed to a single insect and the same insects that were used in the transmission trial were identified. One spittlebug (Cercopidae) Lepyronia quadrangularis Say, one P. spumarius, and one leafhopper in the genus Latalus (Cicadellidae: Deltocephalinae) were identified as vectors. The phytoplasma-positive seedlings showed stunting and yellowing, and died shortly after testing. Other insects captured and identified in the survey were A. atomarius, Neophilaenus lineatus L., Metcalfa pruinosa Say, Amblysellus curtisii Fitch and individuals in the genera Draeculacephala, Elymana, Empoasca, Mesamia, Stroggylocephalus, and Ceratagallia. S. luteolus was not captured during this sampling but was captured on yellow sticky traps and in light traps in previous years at other locations on the campus. This is the first report suggesting that L. quadrangularis and Latalus sp. can serve as natural vectors of EY. References: (1) P. Herath et al. Plant Dis. 94:1355, 2010. (2) H. Lorenz et al.

Abstract
OBJECTIVE The aim of this study was to explore patients' perceptions of the role of the radiologist in their care. METHODS The questionnaire used was designed in conjunction with a psychologist who had an interest in oncology, and piloted. The final questionnaires were distributed to patients attending the breast clinic at St James's Hospital, Dublin, Ireland, from 1 March to 1 July 2011. Patients requiring imaging (mammography and/or ultrasound) were asked to complete the same questionnaire again after imaging procedures were performed. Paired t-tests were used to assess for changes in parameters, including ranking of members of the breast care team in order of perceived importance and levels of anxiety pre and post consultation with the radiologist. RESULTS 306 patients were recruited. 76% of patients thought that radiologists were radiographers and only 14% knew that radiologists were medical doctors. Nearly 40% of patients did not consider that radiologists had a role to play in their care. There was no statistically significant difference in the ranking of team members pre and post consultation. There was a significant improvement in patient anxiety levels after consultation with the breast radiologist, which is likely to be due to the patient learning the outcome of tests performed. CONCLUSION There is a lack of awareness amongst patients and amongst our colleagues in paramedical disciplines regarding the roles and responsibilities of the modern radiologist. ADVANCES IN KNOWLEDGE Radiology must act to increase public awareness so that future changes in the health service will reflect the scope and importance of the speciality.

Abstract
The population dynamics and prevalence of Fasciola hepatica in Galba truncatula were investigated on the Teagasc hill sheep farm in Country Mayo, Ireland from August 2006 until March 2008. Galba truncatula (n=974) were collected at fortnightly intervals in 4 snail habitats on the farm, their relative density and mean monthly rainfall and temperature were recorded. Snail abundance was associated with rainfall and temperature. G. truncatula abundance was generally low during winter 2006/2007 (December 2006-February 2007), mid spring and summer 2007 (April-July) and late autumn and winter 2007/2008 (October 2007-February 2008). Overall, two peaks in G. truncatula abundance were evident during the study period, an early spring (March) and late summer/autumn (late August-October) peak. Seasonal differences were observed in the prevalence of F. hepatica in G. truncatula, the greatest prevalence was evident in 2007 during the summer (25%) and autumn (16%). Two seasonal transmission peaks, as evident by the presence of mature infections in snails, one in summer/autumn and the other in late winter/early spring. Not unsurprising, cercariae (28%) and rediae (29%) were the predominant developmental stages observed in mature and pre-adult snails respectively. Worthy of note in this study, cercariae were also evident in pre-adult snails. The present study highlights the influence of milder temperatures and wetter conditions on both snail and fluke development. If the trend in mild and wet weather conditions continues, there is the potential for an increase in the number of G. truncatula habitats and ultimately the prevalence of fasciolosis in grazing livestock in Ireland.

Abstract
Accurate interpretation of X-ray images is dependent on image viewing conditions. A recent study in Ireland demonstrated that even with the advent of digital departments the majority of images are still viewed using viewing boxes. This investigation aimed to measure average viewing box brightness, percentage uniformity and ambient light levels in radiology and radiographer viewing areas and wards within three major Dublin hospitals. The results were compared with published recommendations by the World Health Organization and Commission of the European Communities. Following analysis of more than 4650 measurements, it was shown that mean values for average viewing box brightness for all departments failed to achieve recommended levels. Only one third of areas met the most lenient guideline for percentage uniformity. Ambient lighting was shown to be unacceptable for ward areas. For all three parameters, radiology areas generally fared best, with wards gaining the poorest scores. Following a 3 min cleaning regimen of viewing boxes, the average brightness and percentage uniformity were improved in 100% and 80%, respectively, of viewing boxes, but average brightness values remained below recommended levels. The importance of comprehensive quality assurance programmes for viewing boxes has been highlighted so that visualization of images is not reduced to sub-optimal levels. The need for consistent and more informative recommendations has been emphasized.

Abstract
BACKGROUND Seasonal affective disorder (SAD) is characterized by recurrent episodes of depression occurring regularly with the onset of winter. METHOD The study was a prospective naturalistic follow-up of the emergence of symptoms of seasonal depression with the passage of time and change in seasons. Participants were screened during summer for SAD. Participants were excluded if they were depressed (BDI > 14) during the summer reruitment. Eligible participants prospectively monitored their mood and anxiety by completing the BDI and BAI every 2 weeks from 1 September through to the 31 March. RESULTS Forty-five participants met criterion for SAD were included in the final data analyses. Depression scores rose gradually over the 30 week period reaching a peak median score around weeks 22 to 24 (January-February). The 'hallmark' physiological symptoms (changes in sleep, appetite and fatigue) emerged earlier in the winter period than cognitive symptoms. The emergence of anxiety symptoms was highly correlated with depressive symptoms, although the median anxiety scores did not reach a clinically significant level. Low self-esteem and poor perceived social support were significantly related to an earlier onset in the emergence of depressive symptoms. Both these factors together resulted in the speediest onset of depression. Poor perceived social support, but not low self-esteem, was associated with earlier emergence of anxiety symptoms. CONCLUSIONS Physiological symptoms may activate negative cognitions in individuals with risk factors of low self-esteem and poor social support so that the disorder is precipitated earlier and is of longer duration.

Abstract
A conventional giant cell tumor of the proximal femur recurred twice locally and developed pulmonary nodules. The lung lesions were felt to be an example of "benign" metastases. Eight months after the initial presentation, the patient developed a single skin nodule on the contralateral leg. Histologic features of the skin nodule showed conventional giant cell tumor identical to the bone lesion. This nodule is a manifestation of arterial metastasis typical of any malignant tumor and seemingly contradicts the concept of "benign" metastasis.

Abstract
Reliability and concurrent validity of the Movement Assessment Battery for Children were evaluated with a sample of 106 boys and girls, distributed into four age groups: 5-6 yr. (n = 20), 7-8 yr. (n = 20), 9-10 yr. (n = 46), and 11-12 yr. (n = 20). Test-retest reliability of the Movement Assessment Battery for Children, estimated using intraclass correlation coefficients, was high across all age groups, and concurrent validity yielded moderate Pearson correlation coefficients between the Move ment battery and long and short forms of the Bruininks-Oseretsky Test of Motor Proficiency. These results support the use of the Movement battery as a measure of motor ability in children, ages 5 to 12 years.

Abstract
The purpose of this study was to prefabricate a new combined composite (chimeric) flap that consists of four different tissues. The tissues were prefabricated around two independent pedicles that ultimately join as a single main pedicle. In the inguinal area of 36 rats, the saphenous and the superficial inferior epigastric (SIE) pedicles were dissected and prepared as vascular carriers. A fascial graft and a local muscle flap were wrapped around the saphenous pedicle. The SIE pedicle was then implanted under the abdominal skin to supply a future skin flap. An ear cartilage graft was also inserted under the abdominal skin and adjacent to the implanted SIE pedicle. After allowing 2-, 4-, 6-, and 12-week prefabrication periods in different groups of nine animals, the prefabricated tissues were raised around two pedicles nourished by the femoral pedicle and then transferred. Flap survival was assessed by observation, microangiography and histology. The skin flaps showed survival rates of 52 +/- 17% (mean +/- standard error of the mean), 64 +/- 16%, 86 +/- 11%, and 100 +/- 0% of the total areas in the 2-, 4-, 6-, and 12-week prefabricated flaps respectively. None of the control grafts that were prepared on the contralateral side survived totally. A significant difference was found between the 12- and 2-week (p < 0.008), 12- and 4-week (p < 0.02), and 6- and 2-week (p < 0.05) prefabrication groups. Histologically, fascial and cartilage grafts, and portions of muscle were viable in the 2- and 4-week groups. Also, noticeable necrosis was found in the skin flaps in these groups. The muscle showed mild (at 2, 4, and 6 weeks) and moderate (at 12 weeks) atrophy. After prefabrication for 6 weeks, all tissues demonstrated good survival. This study shows that a combined composite flap can be prefabricated successfully in rats after a 6-week period of prefabrication.

Abstract
The article reports the 2-year follow-up of patients suffering persistent symptoms of schizophrenia who entered a single blind randomized controlled trial. Patients were randomly allocated to cognitive-behavioral therapy (CBT) plus routine care (RC), supportive counseling (SC) plus RC, or RC alone. Treatment took place over 3 months, and follow-up was made 12 and 24 months after treatment finished. Sixty-one patients were available to the 2-year follow-up and assessed for positive and negative symptoms and clinical improvement; all of the 87 patients who entered the trial were assessed for relapse over the follow-up period. On all measures, patients who received RC alone did significantly worse at 2 years. There were no significant differences at 2 years between the CBT and SC groups.

Abstract
BACKGROUND Persistent drug-resistant psychotic symptoms are a pervasive problem in the treatment of schizophrenia. AIMS To evaluate the durability of the treatment effects of cognitive-behavioural therapy for chronic schizophrenia one year after treatment termination. METHOD A comparison of clinical outcomes was made at one-year follow-up from a randomised trial of cognitive-behavioural therapy, supportive counselling and routine care alone in the treatment of chronic schizophrenia. RESULTS Seventy out of the 72 patients (97%) who completed treatment were assessed at follow-up. There were significant differences between the three groups when positive and negative symptoms were analysed by means of ANCOVAs. Between-group comparisons indicated significant differences between cognitive-behavioural therapy and routine care at follow-up for positive symptoms. There was a trend towards significance for both cognitive-behavioural therapy and supportive counselling to be superior to routine care alone on negative symptoms. CONCLUSIONS At 12-month follow-up the significant advantage of cognitive-behavioural therapy compared to routine care alone remained.

Abstract
A liveborn and subsequently thriving child was delivered abdominally from a pregnancy in a rudimentary noncommunicating uterine horn. This is the 13th English language report of neonatal survival from such an unusual and life-threatening situation. The case presents some 'clues' in the history and a review of the literature suggests that the previously reported bleak outlook for these pregnancies can now be tempered with cautious optimism. Ultrasound diagnosis of Müllerian abnormalities during pregnancy remains difficult but has been reported in several other cases in the literature and may become more common in the future.

Abstract
BACKGROUND Outpatient-based treatments for patients suffering from chronic schizophrenia inadvertently exclude a significant proportion of subjects because they are often too poorly motivated to attend for treatment. In addition there are also concerns about whether the skills that are learnt in a hospital setting will generalize to situations when the individuals are at home. This study attempted to redress some of these potential deficiencies and followed on from an earlier local study which found that a community-based team met more of the needs of patients suffering from chronic schizophrenia. METHOD Seventy-five patients suffering from chronic schizophrenia were allocated randomly to receive traditional outpatient-based or home-based rehabilitation from a clinical psychologist and an occupational therapist. They were assessed before and after 9 months of treatment on a range of clinical, social and quality of life outcomes. Distress to carers was also assessed. Readmission to hospital was recorded for each subject. RESULTS There were significant reductions in socially embarrassing behaviour (SBS), increases in interpersonal functioning and recreational activities and a trend for quality of life to improve in the home-based group. There were fewer admissions in the home-based group but the differences, although financially substantial, were not statistically significant. CONCLUSIONS The home-based rehabilitation service was well received by the majority of patients suffering from chronic schizophrenia and led to some improvement in social behaviour, interpersonal functioning, recreational activities and quality of life.

Abstract
OBJECTIVE To determine the efficacy of teaching patients with bipolar disorder (manic-depressive psychosis) to identify early symptoms of relapse and seek prompt treatment from health services. DESIGN Single blind randomised controlled trial with matching on four baseline variables using a minimisation algorithm. SETTING Mental health services in four NHS trusts (one teaching, three non-teaching). SUBJECTS 69 patients with bipolar disorder who had had a relapse in the previous 12 months. INTERVENTIONS Seven to 12 individual treatment sessions from a research psychologist plus routine care or routine care alone. MAIN OUTCOME MEASURES Time to first manic or depressive relapse, number of manic or depressive relapses, and social functioning examined by standardised interviews every six months for 18 months. RESULTS 25th centile time to first manic relapse in experimental group was 65 weeks compared with 17 weeks in the control group. Event curves of time to first manic relapse significantly differed between experimental and control groups (log rank 7.04, df=1, P=0.008), with significant reductions in the number of manic relapses over 18 months (median difference 30% (95% confidence interval 8% to 52%), P=0.013). The experimental treatment had no effect on time to first relapse or number of relapses with depression, but it significantly improved overall social functioning (mean difference 2.0 (0.7 to 3.2), P=0.003) and employment (mean difference 0.7 (0.1 to 1.3), P=0.030) by 18 months. CONCLUSION Teaching patients to recognise early symptoms of manic relapse and seek early treatment is associated with important clinical improvements in time to first manic relapse, social functioning, and employment.

Abstract
National inpatient and ambulatory surgery data were combined to examine changes over time in the location and amount of surgical care. The main pattern was a decline in the rate of inpatient operations that was outweighed by growth in ambulatory operations. However, the rate of inpatient operations did not decrease for patients age 65 years or over, despite the growth in ambulatory surgery. Other patterns seen for specific types of operations were the substitution of ambulatory for inpatient operations, increases primarily in the rate of inpatient operations, and decreases in total operations. These patterns have implications for control of health care costs.

Abstract
The limitations of biochemical treatments in reducing the severity of hallucinations and delusions has led to an increased interest in the investigation of psychological treatments for these symptoms. These investigations have spanned the last 4 decades and have covered a range of psychological approaches from psychoanalytically oriented psychotherapy to behavioral approaches. More recently, findings that some psychotherapies are not effective treatments for psychosis and that cognitive-behavior therapy can be an effective treatment for neurotic disorders have led to increasing interest in the investigation of the effectiveness of cognitive-behavior therapy for psychosis. This review describes and evaluates the research on the cognitive-behavioral treatment of hallucinations and delusions and describes the cognitive models from which the treatments have developed. The conclusion is that, on the whole, the literature provides fairly strong evidence for the efficacy of cognitive-behavioral approaches in the management of chronic psychotic disorders and associated symptoms, although there are a number of areas where further development is necessary.

Abstract
The volar plate (VP) is critical to the stability of the proximal interphalangeal joint. This study clarifies the macro- and micro-architectural structure of the VP and correlates these findings with its functional properties. Microscopic evaluation of cadaver specimens revealed a trilaminar structure of the VP with differential orientation and organization of collagen fibers in the volar, central core, and dorsal check rein sections of the plate. This description differs from the existing literature and adds to the understanding of the functional properties of the VP. The most important finding is a dense "basket weave" of collagen fibers oriented in 2 perpendicular planes within the central core of the VP. This orientation may contribute primarily to the resistance of the VP to both longitudinal and torsional stress. This study adds to the understanding of the histologic basis for the function of the VP and the mechanisms involved in its injury.

Abstract
A case of an intraarticular epithelioid sarcoma is presented. The patient was a 35 year old man who presented with a 10 months history of a chronic monoarthritis. The MRI showed a diffuse lesion involving the synovial membrane of the knee. There was a marked increased signal on T2 weighted images. Most epithelioid sarcomas involve the subcutaneous tissues of the hands or feet. This presentation is unusual and this entity should be considered in the differential diagnosis of an intraarticular proliferative process.

Abstract
OBJECTIVES To investigate whether intensive cognitive behaviour therapy results in significant improvement in positive psychotic symptoms in patients with chronic schizophrenia. DESIGN Patients with chronic schizophrenia were randomly allocated, stratified according to severity of symptoms and sex, to intensive cognitive behaviour therapy and routine care, supportive counselling and routine care, and routine care alone. SETTING Adjunct treatments were carried out in outpatient clinics or in the patient's home. SUBJECTS 87 patients with persistent positive symptoms who complied with medication; 72 completed treatment. OUTCOME MEASURES Assessments of positive psychotic symptoms before treatment and 3 months after treatment. Number of patients who showed a 50% or more improvement in symptoms. Exacerbation of symptoms and rates of readmission to hospital. RESULTS Significant improvements were found in the severity (F=5.42, df =2,86; P=0.006) and number (F=4.99, df=2,86; P=0.009) of positive symptoms in those treated with cognitive behaviour therapy. The supportive counselling group showed a non-significant improvement. Significantly more patients treated with cognitive behaviour therapy showed an improvement of 50% or more in their symptoms (chi2=5.18, df=1; P=0.02). Logistic regression indicated that receipt of cognitive behaviour therapy results in almost eight times greater odds (odds ratio 7.88) of showing this improvement. The group receiving routine care alone also experienced more exacerbations and days spent in hospital. CONCLUSIONS Cognitive behaviour therapy is a potentially useful adjunct treatment in the management of patients with chronic schizophrenia.

Abstract
OBJECTIVES This report presents estimates of surgical and nonsurgical procedures performed in the United States during 1994. Data are presented by characteristics of patients, region of the country, and procedure categories for ambulatory and inpatient procedures separately and combined. METHODS Estimates in this report are based on data collected from the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery (NSAS). The NHDS provides data on hospital inpatient care, and the NSAS provides data on ambulatory surgery in hospitals and in freestanding ambulatory surgery centers. For the NHDS, data were collected for approximately 277,000 discharges from 478 non-Federal short-stay hospitals (93 percent response rate). For the NSAS, data were collected for about 118,000 ambulatory surgery discharges from 494 hospitals and freestanding ambulatory surgery centers (80 percent response rate). RESULTS An estimated 68.4 million procedures were performed on 38.0 million discharges from hospitals and freestanding ambulatory surgery centers during 1994: 40.7 million procedures were for inpatients, and 27.7 million were for ambulatory patients. Females had more procedures than males did and the rate of procedures increased with age in both ambulatory and inpatient settings. The leading procedures for ambulatory surgery patients and inpatients combined were endoscopy of large intestine, arteriography and angiocardiography, endoscopy of small intestine, and extraction of lens.

Abstract
The distribution of genetic variation for NAD+ malic enzyme (ME*) polymorphism in the Atlantic salmon was assessed in both anadromous and resident populations. The analysis revealed a major allelic divergence between North America and Europe. The *80 variant occurred in 39 of 40 North American samples, ranging in frequency from 0 to 0·515. In contrast, it was detected in only three fish from two of the 35 European locations analysed. Eleven fish from two rivers in north-west France had the *110 variant. While heterogeneity among North American populations was significant, no regional differentiation was apparent and anadromous and resident salmon were not found to differ.

Abstract
The objective of this study was to assess the association of ossification of the coracoacromial ligament (CAL) observed on conventional radiographs with the presence of rotator cuff pathology as demonstrated by magnetic resonance imaging (MRI), arthrography, and/or surgery. Conventional radiographs (internal and external rotation and outlet and axillary views) on eight patients showed ossification of the coracoacromial ligament. Rotator cuff integrity was assessed by physical examination in all 8 patients, by arthrography in 3 patients, and by MRI in 2 patients. Surgery was performed on four of the patients. Physical examination showed impingement findings and decreased rotator cuff strength suggestive of rotator cuff disease in all eight patients. The arthrograms and MRI examinations showed the presence of full-thickness rotator cuff tears. Four of these patients underwent surgery and the rotator cuff defects were confirmed and repaired. Identification of ossification of the CAL on conventional radiographs should be recognized as strongly suggestive of associated significant rotator cuff pathology.

Abstract
A purification and on-line monitoring procedure for IgM was developed. Perfusion ion-exchange chromatography was used for rapid purification of IgM from ascites fluid and hybridoma supernatant. Crude ascites was directly loaded onto an ion exchanger. Due to the complexity of IgM, a two-step ion-exchange procedure had to be developed. This procedure involved a rapid cation-exchange chromatography capture step followed by further purification using anion-exchange chromatography. High linear velocities, in excess of 3500 cm/h, enabled separations to be performed under 5 min. Purity of the final product by SDS-PAGE was shown to be greater than 95%. Furthermore, the antibodies retained biological activity as measured by indirect immunofluorescence (IIF) and ELISA. The IgM peak was also monitored on-line using a novel peak tracking approach. This involved placing an antibody column (specific to the IgM) prior to the ion-exchange column and operating the ion-exchange column with and without the antibody column in-line. The missing peak that is identified by comparing the two chromatograms indicates where the IgM elutes.

Abstract
The authors analyzed the use of hospitals by patients with a diagnosis of human immunodeficiency virus (HIV) infection, using data from the National Hospital Discharge Survey. In the period 1984-90, the rates of both discharges and days of care for HIV-infected patients rose dramatically. For 1988-90, black males had the highest HIV-related discharge rate, followed by white males and black females, whose rates were similar. The discharge rate for patients with HIV-related diagnoses increased more in the Northeast than in the three other regions of the country. By 1990 the rate for the Northeast was nearly triple the rate for other major regions. More than half of female and black patients with HIV-related diagnoses were hospitalized in the Northeast. Private insurance was the principal expected source of payment for the care of half of the HIV-infected patients discharged in 1985, but for only a third in 1990. Medicaid covered 40 percent of the patients with HIV-related diagnoses discharged in 1990. Larger proportions of female than male patients and of black patients than white patients were covered by Medicaid. Acquired immunodeficiency syndrome was the diagnosis coded for most patients with an HIV-related diagnosis, but in larger proportions for patients who were male or white patients. Nonspecific HIV diagnoses were coded for larger proportions of female and black patients. HIV-infected patients had an average of 3.6 diagnoses in addition to their HIV diagnosis. Nearly a fourth of the additional diagnoses were for other infectious diseases, such as pneumocystosis or candidiasis. Anemia, pneumonia, and drug use and dependence also were frequent diagnoses.
