Adverse obstetric history is not a risk factor for poor outcome after ventral rectopexy for obstructive defaecation syndrome.

AIM: Ventral rectopexy (VR) has gained popularity in the management of obstructive defaecation syndrome (ODS) due to a symptomatic rectocele ± intussusception. Data on the efficacy and safety of VR are variable and there are few predictors of successful outcome. This study aimed to examine whether or not an adverse obstetric history influenced the functional outcome following VR for ODS. METHOD: This was a retrospective study of a cohort of 76 consecutive patients who had undergone VR for ODS at a tertiary referral centre between 2012 and 2015. Patients were followed up by telephone questionnaire. The obstetric history and pre- and postoperative symptoms of ODS and faecal incontinence (FI) were obtained from telephone interviews. RESULTS: In this cohort, symptoms of ODS were significantly improved by surgery, with 56% of patients showing a reduction of symptoms of 50% or more (P < 0.001). Subgroup analysis demonstrated that a lower body mass index (BMI; 24.4 vs 27.3 kg/m2 ; P < 0.05) and shorter duration of symptoms (7 vs 10 years; P < 0.05) led to a better outcome. VR had no effect on FI. Obstetric factors such as foetal weight, instrumental delivery, episiotomy, perineal tear and total number of deliveries did not influence outcomes. CONCLUSION: Patients with a less straightforward obstetric history can be reassured that this should not adversely influence the functional outcome after VR for ODS. Colorectal surgeons who offer this surgery should warn patients with an elevated BMI or with longstanding symptoms that the operation may be less successful than for those with a lower BMI or shorter duration of symptoms.

Madarosis: a qualitative study to assess perceptions and experience of Australian patients with early breast cancer treated with taxane-based chemotherapy.

PURPOSE: Eyebrow and eyelash loss (madarosis) is a common and distressing side effect of chemotherapy for which no protective strategies have yet been developed. The purpose of this study was to develop an overview of perceptions and experiences of women undergoing taxane-based treatment for early breast cancer. METHODS: A total of 25 women with a diagnosis of invasive early breast cancer participated in a focus group (n = 5), ages ranging from 35 to 64 (median 50), all had completed therapy with a taxane-based chemotherapy treatment. This focus group used targeted questions to explore participants' perceptions and experience of madarosis during and following chemotherapy and identified issues associated with impact of madarosis on quality of life (QoL). Thematic analysis was conducted to identify important issues experienced by participants. RESULTS: Seven themes emerged from the data: (1) timing of regrowth and permanent changes, (2) meaning/importance of eyebrow/eyelashes, (3) preparedness/information given, (4) impact of the hair loss of self, (5) impact of hair loss on others, (6) physiological side effects of loss of eyebrows/eyelashes, and (7) management of loss of eyebrows/eyelashes. In addition, participants noted physical symptoms of eye irritation during their treatment that they attributed to madarosis. CONCLUSION: This study highlights the significant impact of madarosis on patients, providing the first published analysis of patient's attitude and perception of eyelash and eyebrow loss during chemotherapy. Further research in this area is required and will be benefitted from the development of a dedicated instrument/questionnaire that can capture and measure the impact of madarosis on QoL and allow development of clinical trial strategies.

The international phase 4 validation study of the EORTC QLQ-SWB32: A stand-alone measure of spiritual well-being for people receiving palliative care for cancer.

The EORTC Quality of Life Group has just completed the final phase (field-testing and validation) of an international project to develop a stand-alone measure of spiritual well-being (SWB) for palliative cancer patients. Participants (n = 451)-from 14 countries on four continents; 54% female; 188 Christian; 50 Muslim; 156 with no religion-completed a provisional 36-item measure of SWB plus the EORTC QLQ-C15-PAL (PAL), then took part in a structured debriefing interview. All items showed good score distribution across response categories. We assessed scale structure using principal component analysis and Rasch analysis, and explored construct validity, and convergent/divergent validity with the PAL. Twenty-two items in four scoring scales (Relationship with Self, Relationships with Others, Relationship with Someone or Something Greater, and Existential) explained 53% of the variance. The measure also includes a global SWB item and nine other items. Scores on the PAL global quality-of-life item and Emotional Functioning scale weakly-moderately correlated with scores on the global SWB item and two of the four SWB scales. This new validated 32-item SWB measure addresses a distinct aspect of quality-of-life, and is now available for use in research and clinical practice, with a role as both a measurement and an intervention tool.

Measurement of chemotherapy-induced alopecia-time to change.

Data on chemotherapy-induced alopecia (CIA) as a side effect of cancer treatment are scarce. CIA is given minimal attention in clinical trials and in the literature. However, when asking the patients with cancer for their opinion, CIA appears to have a major impact, particularly on body image and quality of life. Currently, there is no commonly used measure to evaluate CIA; It is time to improve the management and measurement of CIA.

Rapid in situ chondrocyte death induced by Staphylococcus aureus toxins in a bovine cartilage explant model of septic arthritis.

OBJECTIVE: To assess in situ chondrocyte viability following exposure to a laboratory strain and clinical isolates of Staphylococcus aureus. METHODS: Bovine cartilage explants were cultured in the presence of S. aureus 8325-4 (laboratory strain), clinical S. aureus isolates or non-infected culture medium of pH values 7.4, 6.4 and 5.4. All clinical isolates were isolated from the joint aspirates of patients presenting with S. aureus-induced septic arthritis (SA). At designated time points, in situ chondrocyte viability was assessed within defined regions-of-interest in the axial and coronal plane following live- and dead-cell image acquisition using the fluorescent probes 5-chloromethylfluorescein diacetate (CMFDA) and propidium iodide (PI), respectively, and confocal laser-scanning microscopy (CLSM). Cartilage water content, following S. aureus 8325-4 exposure, was obtained by measuring cartilage wet and dry weights. RESULTS: S. aureus 8325-4 and clinical S. aureus isolates rapidly reduced in situ chondrocyte viability (>45% chondrocyte death at 40 h). The increased acidity, observed during bacterial culture, had a minimal effect on chondrocyte viability. Chondrocyte death commenced within the superficial zone (SZ) and rapidly progressed to the deep zone (DZ). Simultaneous exposure of SZ and DZ chondrocytes to S. aureus 8325-4 toxins found SZ chondrocytes to be more susceptible to the toxins than DZ chondrocytes. Cartilage water content was not significantly altered compared to non-infected controls. CONCLUSIONS: Toxins released by S. aureus have a rapid and fatal action on in situ chondrocytes in this experimental model of SA. These data advocate the prompt and thorough removal of bacteria and their toxins during the treatment of SA.

One year on: assessing the impact of coronavirus disease 2019 on demand for semi-urgent ENT services.

OBJECTIVE: This study investigated how the coronavirus disease 2019 pandemic has impacted on presentations to ENT first-on-call services. METHODS: All appointments to a rapid access triage clinic from 1 June to 31 August in 2019 and 2020 were reviewed retrospectively and their reasons for consultation classified. A binomial proportion test was used to determine whether the proportions of consultations per presentation differed significantly between years. This analysis was repeated with the number of unique patients per presenting complaint. RESULTS: The proportions of nine reasons for consultation differed significantly between 2019 and 2020, including an increase in otitis media and nasal trauma presentations, and a decrease in otitis externa and tonsillitis presentations. Reattendances caused some variation in the frequency of certain diagnoses. CONCLUSION: Our data suggest a shift in the presentations to first-on-call services, which may be a result of changes in patient behaviour and access to healthcare services.

Shift work and work injury in the New Zealand Blood Donors' Health Study.

OBJECTIVE: To investigate associations between work patterns and the occurrence of work injury. METHODS: A cross sectional analysis of the New Zealand Blood Donors Health Study conducted among the 15 687 (70%) participants who reported being in paid employment. After measurement of height and weight, a self-administered questionnaire collected information concerning occupation and work pattern, lifestyle behaviour, sleep, and the occurrence of an injury at work requiring treatment from a doctor during the past 12 months. RESULTS: Among paid employees providing information on work pattern, 3119 (21.2%) reported doing shift work (rotating with nights, rotating without nights, or permanent nights) and 1282 (8.7%) sustained a work injury. In unadjusted analysis, work injury was most strongly associated with employment in heavy manual occupations (3.6, 2.8 to 4.6) (relative risk, 95% CI), being male (1.9, 1.7 to 2.2), being obese (1.7, 1.5 to 2.0), working rotating shifts with nights (2.1, 1.7 to 2.5), and working more than three nights a week (1.9, 1.6 to 2.3). Snoring, apnoea or choking during sleep, sleep complaints, and excessive daytime sleepiness were also significantly associated with work injury. When mutually adjusting for all significant risk factors, rotating shift work, with or without nights, remained significantly associated with work injury (1.9, 1.5 to 2.4) and (1.8, 1.2 to 2.6), respectively. Working permanent night shifts was no longer significantly associated with work injury in the adjusted model. CONCLUSION: Work injury is highly associated with rotating shift work, even when accounting for increased exposure to high risk occupations, lifestyle factors, and excessive daytime sleepiness.

Prognostic significance of the metastasis-inducing protein S100A4 (p9Ka) in human breast cancer.

The calcium-binding protein S100A4 is capable of inducing metastasis in rodent models for breast cancer. We now show that rabbit antibodies to recombinant rat S100A4 recognize specifically human S100A4 using Western blotting techniques and use them to assess the prognostic significance of S100A4 in primary tumors from a group of 349 patients treated between 1976 and 1982 for stage I and stage II breast cancer. The antibody stains normal breast tissue heterogeneously, but stains positively 41% of the carcinomas, leaving the remaining 59% as negatively stained. In addition to the carcinoma cells, some host stromal cells and lymphocytes are also stained, but these have been discounted in subsequent analyses. There is an association of staining of carcinomas for S100A4 with some tumor variables considered to be associated with poor prognosis for patients: tumor present in axillary lymph nodes (borderline P = 0.058), staining for c-erbB-3 (P = 0.002), cathepsin D (P = 0.024), and c-erbB-2 (P = 0.048). The association of staining for S100A4 with patient survival has been evaluated using life tables and analyzed using generalized Wilcoxon statistics. Eighty percent of the S100A4-negative patients but only 11% of the S100A4-positive patients are alive after 19 years of follow-up, and this association is highly significant (P < 0.0001); the former have a median survival of >228 months and the latter 47 months. The other tumor variables that show significant association with survival time are nodal status (P < 0.0001), tumor size (P = 0.0035), histological grade (P = 0.013), staining for c-erbB-2 (P = 0.0015), estrogen receptor (P = 0.028), and p53 (P = 0.032). Analysis of the association of patients with carcinomas staining for S100A4 and their survival in subgroups defined by these other tumor variables shows that in each subgroup, staining for S100A4 is associated with poorer survival. Patients whose tumors stain for S100A4 and possess involved lymph nodes (P < 0.0001), which are fixed to the chest wall (P = 0.015) or which stain for c-erbB-2 (P = 0.050), show a significant reduction in survival times over those with only S100A4-staining tumors. Patients with involved lymph nodes, or staining for c-erbB-2 in the S100A4-negative group fail to show any significant reduction in survival times. Multivariate regression analysis for 137 patients shows that staining for S100A4 is most highly correlated with patient deaths (P < 0.0001), but involved lymph nodes (P = 0.001), fixed tumors (P = 0.0002), and high histological grade (P = 0.022) are also significant independent prognostic variables. These results suggest that in this group of patients, the metastasis-inducing protein S100A4 is most tightly correlated with patient demise.

Protein kinase C alpha expression in normal breast, ductal carcinoma in situ and invasive ductal carcinoma.

The purpose of this study was to determine if Protein Kinase C alpha (PKC alpha) is altered in expression or localisation in normal breast, ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC). We obtained 14 mixed cases of invasive ductal carcinoma (IDC) and DCIS, 36 pure DCIS cases and 25 cases of normal breast. The sections were stained immunohistochemically for PKC alpha expression. Staining was cytoplasmic. The results showed a progressive reduction in staining intensity from normal breast to invasive ductal carcinoma. The staining pattern was heterogeneous in the cytoplasm of DCIS and IDC, but homogeneous in the cytoplasm of normal breast ductal epithelium. Interestingly, mitotic cells and cells with aberrant nuclear morphology showed increased cytoplasmic staining in DCIS and IDC. PKC alpha activity is altered in dividing or abnormal cells, but overall expression is reduced in IDC. This raises the possibility of an alteration in the subcellular localisation of PKC alpha which may relate to changes in desmosomal adhesive state.

Long-term prognostic significance of thymidine labelling index in primary breast cancer.

Tumour growth rates, as measured by incorporation of tritiated thymidine, have been reported as being of prognostic importance in breast cancer. We have measured the thymidine labelling index (TLI) of 185 early breast cancers, followed-up for a minimum of 8 years. Above median TLI was associated with higher tumour grade, but not with other prognostic factors. TLI was not predictive of survival in either univariate or multivariate analysis. The inter- and intra-observer reproducibilities of TLI measurements were poor, which may be a factor limiting its usefulness as a prognostic indicator in breast cancer.

The objective measurement of remission and progression in metastatic breast cancer by use of serum tumour markers. European Group for Serum Tumour Markers in Breast Cancer.

An established biochemical index for monitoring therapy in patients with metastatic breast cancer was tested prospectively in a multicentre study. The index uses two serum tumour markers--carcinoembryonic antigen (CEA) and carbohydrate antigen 15-3 (CA15-3) along with erythrocyte sedimentation rate (ESR). 67 patients treated by either endocrine or chemotherapy had CA15-3, CEA and ESR measured at diagnosis of metastases and sequentially during therapy. Two markers, CA15-3 and CEA, were measured on a further 16 patients giving a total of 83 patients who were assessable for CA15-3 and CEA. Of the patients with CA15-3, CEA and ESR measured at diagnosis of metastases 84% (56/67) had elevation of 1 or more markers. During therapy the number with elevated marker(s) rose to 96% (64/67). Changes in the markers were in line with and often pre-dated therapeutic outcome as assessed by the International Union Against Cancer (UICC) criteria both for remission and progression. Patients without elevation of markers on diagnosis subsequently showed a rise in the marker(s) at or before documented disease progression by UICC. The 3 women in whom markers were at no time significantly elevated remain in remission. The results using CA15-3 and CEA were similar but 12% less patients were assessable. CA15-3 and CEA (with and without ESR) provide an objective method to guide therapy in patients with metastatic breast cancer.

Immunocytochemical identification of cell types in benign and malignant breast diseases: variations in cell markers accompany the malignant state.

We performed immunocytochemical staining of benign, in situ, and malignant breast disease to identify antigens related to the presence of the major parenchymal cell types of the normal breast. Markers for the epithelial cells, antiserum to epithelial membrane antigen, and three monoclonal antibodies (MAb) to milk-fat globule membranes stained most of the inner cells in benign breast lesions, carcinoma in situ, and invasive carcinomas, but the peripheral cells in benign lesions, as well as in carcinoma in situ, were unstained. MAb to epithelium-specific keratin 18 stained the majority of inner cells in benign breast lesions but comparatively fewer such cells in carcinoma in situ and invasive carcinoma. Markers for the myoepithelial cells, antisera, and MAb to smooth muscle actin and vimentin stained most of the peripheral cells in benign breast lesions and in carcinoma in situ but failed to stain virtually any neoplastic cells in invasive carcinomas. Markers for the basement membrane adjacent to the myoepithelial cells, antiserum, and MAb to laminin and Type IV collagen delineated an intact basement membrane around benign lesions and carcinoma in situ, and fragmented structures in 5-10% of invasive carcinomas; the remaining carcinomas were largely unstained. Markers for both myoepithelial and epithelial cells, keratin MAb PKK2 and LP34, stained most of the inner cells in benign lesions but usually only relatively few malignant cells in carcinoma in situ and invasive carcinomas. Markers for the secretory alveolar cell, MAb to beta- and kappa-casein, stained a few isolated cells in benign lesions, many more inner cells in two such lesions in pregnant females, and none in invasive carcinomas. In conclusion, the myoepithelial cell and, under suitable hormonal conditions, the secretory alveolar cell, are retained in most benign lesions, but they are largely lost in invasive carcinomas.

Ophthalmology at St. Thomas' Hospital, London: the 12th to the 19th centuries.

The author recounts the history of St. Thomas' Hospital from its medieval beginnings to its establishment by the end of the 19th century as one of London's twelve teaching hospitals. Among the members of its staff have been some of the first and most illustrious ophthalmologists--those whose discoveries, teachings and writings have contributed to the foundation and development of ophthalmology.

Dr. William Briggs: ophthalmic physician at St. Thomas' Hospital, London.

William Briggs, MD, established himself as one of the first ophthalmic physicians, whom today we would call a neuro-ophthalmologist, to practice in the United Kingdom. After graduating with an MD from Cambridge in 1677, and while a Fellow of Corpus Christi College, he carried out original studies in visual anatomy and physiology. He described and named the optic papilla and the retinal nerve fibers in his book Ophthalmographia, published in 1676. He published his New Theory of Vision in 1682. While at Cambridge, he was a contemporary and a friend of Isaac Newton, with whom Briggs worked but who, in matters of visual anatomy and physiology, came to reach different conclusions from Briggs. In 1683, Briggs came to London to practice as a physician at St. Thomas' Hospital, where he established a considerable reputation as an ophthalmologist. For political reasons he was forced to resign from the Hospital prematurely.

The value of guidelines in a breast screening service.

The use of agreed guidelines in the management of common surgical and medical conditions has received much attention and enjoys varying degrees of support. In May 1992 the UK Breast Screening Programme produced guidelines with the intention of providing criteria for all units to attempt to achieve. We have investigated these guidelines as a means of comparative audit and stimulus for change. Two units were compared, one in a teaching centre and the other in a district general hospital. Although both units performed for the most part within the guidelines, areas where improvement could be made were identified and measures to correct deficiencies taken. This resulted in improved performance in those areas. The study demonstrates that guidelines can have considerable benefit in helping to identify problems in the provision of care and introducing measures to improve the situation.

Intermittent isometric fatigue study of the lumbar multifidus muscle in four-point kneeling: an intra-rater reliability investigation.

Back muscle endurance is considered important in low back pain (LBP) rehabilitation. Specific training of multifidus may also be necessary to restore normal low back function. The reliability of surface electromyogram (EMG) to assess endurance of the multifidus muscle during intermittent isometric exercise was evaluated. Multifidus endurance was monitored in the four-point kneeling exercise position using the power spectral analysis method. Twenty healthy volunteers were tested on three separate occasions. Subjects performed repeat 10 s high-intensity voluntary contractions of multifidus for 3 min. The median frequency (MF) and the integrated-rectified (I-R) EMG signal displayed the fatigue pattern of multifidus. Intraclass correlation coefficients indicated fair-good reproducibility for MF (0.48-0.67) but poor reliability for IR-EMG. In conclusion, problems concerning functional testing protocols for the back muscles remain and careful development is necessary for more realistic rehabilitation monitoring.

Variation in the staging of colorectal carcinomas: a survey of current practice.

Dukes' staging is the most common means of staging and grouping colorectal carcinomas and is also used to determine which patients will be offered adjuvant therapies or entered into clinical trials. This study was performed to assess the degree of variation in the staging of colorectal carcinomas in normal clinical practice. Seven consultant surgeons and two consultant pathologists returned questionnaires asking them to stage 14 carcinomas on the basis of their pathology reports alone. The results show agreement among all nine in only six out of the 14 cases. In two cases there was a close to 50:50 split in perceived stage. Between them, the nine consultants produced eight different sets of staging results. These results indicate difficulties in the application of Dukes' staging system for several possible reasons. There may be misinterpretation of the written report, misapplication of the staging system because of unfamiliarity or confusion between the various modifications of Dukes' system which have been published. A more precisely defined staging system based on a standard proforma may be more appropriate in modern clinical practice.

Audit--a cause for TMJ dysfunction.

The last few years have seen those of us in hospital practice confronted by clinical audit and unit budgeting. We have recently been advised, by our unit general manager, that in the next financial year we must make a 1% saving, followed by 2% the subsequent year. Of course, clinical budgeting is nothing new for our colleagues in general practice. They have been working within its confines almost since the inception of the Health Service, in the guise of item of service payment. However, for those of us in hospital practice who have hitherto been relatively cushioned from economic realities, this can come as quite a shock.
