Kinds of Referral Centre Selected AbstractsImpact of neurofibromatosis 1 upon quality of life in childhood: a cross-sectional study of 79 casesBRITISH JOURNAL OF DERMATOLOGY, Issue 4 2009P. Wolkenstein Summary Background, Neurofibromatosis 1 (NF1) has a significant impact on quality of life (QoL). Objectives, To evaluate QoL in NF1 according to phenotype from the viewpoint of children and proxy. Methods, One hundred and forty families with a child aged between 8 and 16 years, seen consecutively at the National Academic Paediatric Referral Centre for NF1 for a phenotype evaluation, were contacted by mail. Families agreeing to participate were sent two questionnaires, the DISABKIDS for children and proxy and the cartoon version of the Children's Dermatology Life Quality Index (CDLQI). QoL scores were compared with those in other major diseases and were analysed according to age, gender and phenotype. Results, Eighty families agreed to participate, and 79 returned the questionnaires. Using DISABKIDS, NF1 had a higher impact on health-related QoL than asthma (mean ± SD 75·18 ± 18·22 vs. 79·78 ± 13·41; P = 0·005). The total score was more altered when assessed by proxy than by children (71·20 ± 17·94 vs. 75·18 ± 18·22; P = 0·002). Orthopaedic manifestations, learning disabilities and presence of at least two plexiform neurofibromas were independently associated with a higher impact (P < 0·01). The CDLQI score was slightly altered (11·3%). Dermatological signs, such as café-au-lait spots and freckling, did not have a significant impact. Conclusions, Orthopaedic manifestations, learning disabilities and plexiform neurofibromas are the main complications impacting on QoL during childhood NF1. QoL could be considered as an endpoint for intervention studies in this context.

Falcinelli's modifications of Strampelli's technique of OOKP surgery remains the gold standard for its excellent visual and keratoprosthesis-retention results. To maintain good outcomes, aid research and to maintain standards, it is important that benchmarks are maintained in patient selection and preoperative assessment, surgical technique and post-operative care. We therefore present, for discussion, the updated protocol that is currently used in the British National OOKP Referral Centre at the Sussex Eye Hospital, Brighton. Methods Members of the OOKP Study Group met in Rome, Italy in 2001 and Vienna, Austria in 2002 to produce and up-to-date standard and protocol. Since then, we have continued to update our protocol on the basis of our own outcomes and findings. We present our updated protocol for discussion and for use in other OOKP centres. Results Our updated protocol includes a discussion on the indications and contraindications for surgery, criteria for patient selection, surgical technique, routine postoperative care, and the recognition and management of postoperative complications. Conclusion 5 years have passed since the standards for modified OOKP surgery were published. This paper highlights changes to this standard resulting from our practice in our national OOKP centre. [source] Can objective parameters derived from videofluoroscopic assessment of post-laryngectomy valved speech replace current subjective measures?CLINICAL OTOLARYNGOLOGY, Issue 6 2006An e-tool-based analysis Objectives:, The primary purpose of this study was to assess the pharyngoesophageal segment in total laryngectomy patients using a videofluoroscopy e-tool. Study design:, Cross-sectional study. Setting:,, Head and Neck Oncology Unit, Tertiary Referral Centre. Patients:, Forty-two patients following total laryngectomy. Intervention:, Videofluoroscopy using an e-tool (JRuler). Main outcome measures:, Subjective and objective videofluoroscopy parameters correlated with the GRBAS scale and treatment variables. Results:, Of 32 men and 10 women, mean age 63.5 years (10.8) the majority (64.3%) had a reasonable voice (good = 11 and poor = 4 patients). Comparing subjective and objective parameters, significant correlations were only seen with a smaller minimal neoglottic distance at phonation with no regurgitation of barium at phonation (P = 0.05) and a type 1 shape of neoglottis at phonation (P = 0.02). There were also significant correlations between smaller maximum sub-neoglottic distance at phonation and type 1 shape of neoglottis (P = 0.02), smaller maximum sub-neoglottic distance at rest and absence of stasis of barium at phonation (P = 0.05) and the length of neoglottis at phonation and type 1 shape of neoglottis (P = 0.01). For perceptual evaluation, significant correlation was seen only between G1 voice and a smaller minimal neoglottic distance at phonation (P = 0.03) amongst the subjective and objective parameters. There were no correlations between visual parameters and the clinical parameters. Conclusions:, Our observations suggest that this interesting concept has limitations. While objective and quantifiable data can be obtained using videofluoroscopy in laryngectomees, only a few correlate with each other and with voice quality. [source] Clinical aspects on neonatal cholestasis based on observations at a Swedish tertiary referral centreACTA PAEDIATRICA, Issue 2 2001B Fischler The aim of the study was to investigate the clinical aspects of neonatal cholestasis. The medical records of 85 cholestatic infants were retrospectively reviewed. A majority of the patients were referred from other parts of the country. The most common diagnoses were extrahepatic biliary atresia (n= 30 patients), ,1 -antitrypsin deficiency (n=11) and progressive familial intrahepatic cholestasis (n= 11). On presentation, the biliary atresia group had higher mean serum values of bilirubin, G-GT and cholesterol than the patients with intrahepatic cholestasis, with no significant differences noticed for any other biochemical parameter. A lack of excretion on hepatobiliary scintigraphy was noticed in all investigated patients with biliary atresia, but also in 9 of 34 patients with intrahepatic neonatal cholestasis. There was no statistical correlation between the age at portoenterostomy and the outcome in patients with biliary atresia. However, both the detection of a partial flow on perioperative cholangiogram and the establishment of a non-icteric phase within 6 mo after the portoenterostomy correlated to a good outcome. Eight of 11 patients with progressive familial intrahepatic cholestasis were treated with a biliary diversion procedure, five of eight experienced a sustained cholestatic remission. Conclusions: Progressive familial intrahepatic cholestasis may be a more common cause of neonatal cholestasis in Sweden than reported elsewhere and that the experience with biliary diversion is positive. While early referral in patients with extrahepatic biliary atresia remains important, a portoenterostomy should be attempted also in patients referred after 3 mo of age. [source] Investigating moderate to severe paediatric trauma in the Auckland regionEMERGENCY MEDICINE AUSTRALASIA, Issue 2 2010Louise Couch Abstract Objective: To investigate differences between paediatric patients with moderate to severe trauma admitted from two paediatric ED, with respect to: demographics, patterns of presentation, mechanism of injury, injury severity scores (ISS), interventions and outcome. Method: Retrospective cohort study. Moderate to severe trauma was defined as ISS >9. Paediatric patients admitted to hospital via Starship Children's Emergency or KidzFirst ED, with trauma from 1 May 2003 to 30 April 2004, with ISS >9 were identified using multiple databases. The charts were reviewed and data collected included: demographics, hospital of first presentation, diagnoses, ISS, Paediatric trauma score (PTS), Glasgow coma score (GCS), ventilator hours, length of admission, survival and discharge destination. Descriptive statistics with 95% confidence intervals, Mann,Whitney U -test, ,2 -test and Fisher's exact test were used as appropriate. Results: A total of 393 children with moderate to severe trauma were identified using initial search strategies. Of these, 82 children met the inclusion and exclusion criteria for the study; 42 children were admitted via KidzFirst ED and 40 via Starship Children's ED. There was no statistically significant difference in ISS (P= 0.86), PTS (P= 0.11), GCS (P= 0.62), hours on a ventilator (P= 0.28) and length of stay (P= 0.87) between children admitted from Starship or KidzFirst ED. Conclusion: This study suggests that there are no differences in the numbers or severity of paediatric trauma patients admitted from the Starship and KidzFirst ED. This indicates triage is to the closest ED despite having a tertiary referral centre for paediatric trauma available in Auckland City. [source] Head injuries related to sports and recreation activities in school-age children and adolescents: Data from a referral centre in Victoria, AustraliaEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2010Louise M Crowe Abstract Objectives:, Head injuries (HI) in children are common and even mild HI can lead to ongoing cognitive and behavioural changes. We set out to determine the causes of sport-related HI in school-age children presenting to a large urban ED as a basis for future interventions. Method:, Identification and medical record review of all sport-related HI in children aged 6,16 years at a tertiary children's hospital ED in Victoria, Australia, over a 1 year period. Information was collected on demographics, injury variables and radiology findings. HI were classified as mild, moderate and severe based on GCS and radiography reports. Results:, Over 12 months there were 406 HI in school-age children. Seventy per cent were male. A large number of HI (129; 33%) were related to sports. Of these, most were classified as mild and 13% were classified as moderate or severe. Among a range of sports, Australian Rules football was associated with more than 30% of all HI attributable to a sport and recreation cause. Equestrian activities were the main cause of moderate HI. Conclusion:, The present study identified sports as a major cause of HI in the Victorian paediatric emergency setting with Australian Rules football the most commonly involved sport. Further prevention initiatives should consider targeting Australian Rules football and equestrian activities. [source] Prognostic Factors Affecting Long-Term Retention of Topiramate in Patients with Chronic EpilepsyEPILEPSIA, Issue 3 2000S. D. Lhatoo Summary: Purpose: To determine the long-term retention rate of topiramate (TPM) therapy in patients with chronic epilepsy and to identify the relevant prognostic factors that influence retention. Methods: All patients with chronic epilepsy (n = 393) prescribed TPM between October 1, 1995, and December 31, 1998, at a tertiary referral centre for epilepsy were analysed. The retention rate for TPM was calculated by using Kaplan-Meier survival analysis, and the prognostic factors influencing retention were analysed by using Cox regression. Results: Of patients prescribed TPM, 30% continued taking the drug beyond 3 years. Discontinuation was mainly due to adverse events and lack of efficacy. Use of more than one new concurrent antiepileptic drug (AED) and lower maximal daily doses were more likely to result in treatment discontinuation due to adverse events. Older age at onset of epilepsy, a history of having previously taken more than one new AED [lamotrigine (LTG), gabapentin (GBP), or vigabatrin (VGB)], and lower maximal daily doses were more likely to lead to discontinuation due to lack of efficacy. Conclusions: A third of patients with chronic epilepsy started on TPM therapy will continue on treatment for >3 years. Absence of learning disabilities, late age at onset of seizures, previous use of more than one new AED, two or more concurrent AED use, and low maximal daily doses of TPM are more likely to result in discontinuation of medication. These factors should be taken into account when considering the use of TPM for the treatment of chronic epilepsy. [source] Low-Dose Topiramate Versus Lamotrigine in Migraine Prophylaxis (The Lotolamp Study)HEADACHE, Issue 3 2007Praveen Gupta MD Objective.,To assess the efficacy and safety of topiramate and lamotrigine for prophylaxis in patients with frequent migraine as compared to each other and to placebo. Methods.,Sixty patients with frequent migraine (more than 4 attacks per month) from the headache clinic at a tertiary referral centre in India were randomized to receive 50 mg topiramate/lamotrigine or matching placebo for 1 month each in 2 divided doses in 4 phases in a crossover manner with a washout period of 7 days in between. Primary efficacy measure was responder rate (50% decrease in mean migraine frequency/intensity). Secondary efficacy measures included reduction in mean monthly frequency, intensity, duration, rescue medication use, migraine associated symptoms, and adverse events. Statistical analysis.,Analysis was on intention to treat basis. Data were analyzed as correlated data. Generalized estimation equation was used to compute overall mean standard deviation and 95% confidence intervals for each of the outcome variables. Bonferroni's correction done for multiple comparisons. P value of <.017 was taken as significant. Results.,Fifty-seven patients comprised the intent-to-treat population. Four patients withdrew from the study at various phases, none because of the side effects. Responder rate for frequency was significantly higher for topiramate versus placebo (63% vs 30%, P < .001), and versus lamotrigine (63% vs 46 %, P= .02). For intensity of headache also a responder rate of topiramate versus placebo (50% vs 10%, P < .001), and versus lamotrigine (50% vs 41%, P= .01) was observed. Topiramate showed statistically significant benefits (P < .017) in most of the secondary efficacy measures while lamotrigine was beneficial for reduction in headache frequency, and migraine associated symptoms. Adverse events were similar. Conclusion.,Low-dose topiramate is efficacious in migraine prophylaxis as compared to both placebo and lamotrigine. Lamotrigine in low doses might be beneficial for headache frequency; however, longer trials are required to establish its efficacy on the intensity and frequency of migraine. [source] Occupational risks for male fertility: an analysis of patients attending a tertiary referral centreINTERNATIONAL JOURNAL OF ANDROLOGY, Issue 6 2001Sebastian Kenkel The impact of environment and occupation on male fertility is still under debate. We investigated whether certain occupations may be over- or under-represented among men attending our infertility clinic in relation to the entire population of the area. Diagnoses and semen parameters of 2054 infertile men from the district of Münster were analysed retrospectively. The patients were categorized into 29 occupational groups. The relative size of each group was compared with that of the entire population in the district of Münster. Farmers were over-represented compared with the general population. Farmers and painters/varnishers showed a significantly higher proportion of reduced sperm counts [odds ratios (OR): 2.13 and 2.17, 95% confidence intervals: 1.18,3.88 and 1.02,4.65] and severely reduced sperm concentrations compared with the entire group of infertile men; in addition, significantly more farmers presented with a history of maldescended testes than other occupational groups (OR: 2.76 and 2.84; CI: 1.12,6.75 and 1.27,6.34). Metal workers/welders formed significantly higher proportions of patients with reduced sperm motility (OR: 5.99; CI: 1.38,26.00). The relatively poor semen parameters of the painters/varnishers could be caused by exposure to toxins. This may also apply to the farmers (fertilizers, herbicides); however, the elevated rate of maldescended testes suggests an effect of exposure during prenatal development or a genetic cause. The findings for metal workers/welders may be because of heat or toxins at the workplace. The study demonstrates that certain occupations are preferentially associated with male infertility. [source] Low-grade fever: how to distinguish organic from non-organic formsINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2010M. Affronti Summary Background and aim:, Low-grade fever (LGF) is defined as a body temperature between 37.5 and 38.3 °C, which is below the classical value reported for fever of unknown origin (FUO). We attempted to characterise its epidemiology, aetiology and clinical aspects to improve the methodological approach to diagnosis. Design and Methods:, We reviewed and evaluated a survey of patients with LGF, followed as outpatients of our Department, a tertiary referral centre from 1997 to 2008. The same classifications were applied for classical FUO, and in the patients diagnosed with LGF, we also investigated for habitual hyperthermia (HH). Results:, Seventy-three patients were selected and divided into two groups: group A included 32 patients classified with organic fever and group B included 41 patients with HH. Aetiology of organic LGF was: infectious disease 59%; neoplasm 3.1%; inflammatory non-infectious disease 6.2%; miscellaneous 18.7%; undiagnosed 12.5%. Mean age was significantly higher in the organic fever than in the HH group (p < 0.02). Splenomegaly and loss of weight were significantly associated with organic fever (p < 0.05), while dizziness and general malaise were associated with HH. Lack of any pathological signs at physical examination was significantly more frequent in HH (p < 0.0001). Among the biochemical tests, white blood cells and C-reactive protein were more frequently above normal limits in group A than in group B (p < 0.05). Conclusions:, In our experience, LGF requires the same methodological diagnostic approach as FUO, because there is no relationship between body temperature values and the severity of the underlying diseases, and the aetiological spectrum is also the same. [source] The prevalence of vitamin D abnormalities in South Asians with type 2 diabetes mellitus in the UKINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2010A. A. Tahrani Summary Background:, The high prevalence of both hypovitaminosis D and type 2 diabetes (T2DM) in the Asian community is well recognised, but the impact of diabetes on vitamin D status and vice versa, has not been well reported. Aims:, To determine the prevalence of hypovitaminosis D in Asian patients with T2DM and its impact on glycaemic control. Methods:, A cross-sectional study was conducted in a tertiary referral centre in the UK. Two hundred and ten Asian patients aged more than 40 years were included (170 with and 40 without T2DM). Each had a standard bone profile (serum calcium, phosphate and alkaline phosphatase), serum parathyroid hormone and 25-hydroxycholecalciferol. Results:, The prevalence of low serum 25-hydroxyvitamin D (< 50 nmol/l) was high in the group as a whole (> 80%) and more common in diabetics compared with controls (83% vs. 70%; p = 0.07). This was particularly so in men (82.5% vs. 57.9%; p = 0.02). HbA1c was higher in women with vitamin D deficiency (< 12.5 nmol/l) (8.11 ± 1.11% vs. 7.33 ± 1.32%, p = 0.046). In logistic regression analysis, T2DM was an independent predictor of hypovitaminosis D. In linear regression analysis, vitamin D deficiency was independently related to HbA1c in women with T2DM. Conclusions:, Hypovitaminosis D remains a major public health issue in the Asian population and is exaggerated in patients with T2DM. The fact that vitamin D deficient women had higher HbA1c levels raises the possibility that vitamin D replacement may improve glycaemic control. [source] Clinical utility of computed tomography in the assessment of dementia: a memory clinic studyINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2004Kelly A. Condefer Abstract Objective To define the influence of computed tomography (CT) on clinical decision-making in the outpatient evaluation of dementia. Design A case series in which two physicians reviewed standardised data extracted from clinical records, first blind to CT results, and then with CT results. Clinical decisions made with and without the input of CT were compared. The study was based in an outpatient referral centre for the assessment of memory disorders and dementia. The study involved 146 participants who were diagnosed with dementia after their first clinic visit, had Mini Mental State Examination scores >12, were aged >65 years, and had no history of neurologic disease. Results CT impacted on diagnosis in an average of 12% (±2), and on treatment plan in 11% (±2) of cases. Physicians predicted a priori which cases CT may influence with an average sensitivity of 28% (±2), and specificity of 78.5% (±1.5). There was no statistically significant relationship between diagnostically uncertain cases and helpful CT scans [average ,2,=,1.121 (±1.116), p,=,ns]. Blind to CT physicians appropriately identified cerebrovascular disease with an average sensitivity of 63% (±3), and specificity of 93.5% (±3.5). Conclusions In the outpatient setting, CT may be expected to impact on diagnosis and treatment of dementia in 10% to 15% of cases. Memory clinic physicians recognise and treat cerebrovascular risk factors with reasonable sensitivity and specificity without the input of CT. Copyright © 2004 John Wiley & Sons, Ltd. [source] A retrospective study of paediatric oral lesions from ThailandINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2007KITTIPONG DHANUTHAI Aim., To survey the paediatric oral lesions in Thailand. Design., Biopsy records over a 15-year period (1990,2004) were retrieved from the files of the Department of Oral Pathology, Faculty of Dentistry, Chulalongkorn University. Paediatric cases with an age of 16 years or younger were selected. The age of the patients was divided into three groups according to the dentition period. The lesions were classified into three categories: inflammatory/reactive lesions, cystic lesions, and tumour/tumour-like lesions. Results., From a total of 8314 oral biopsies, 1251 cases (15.05%) were in the paediatric population. The greatest number of lesions fell into the cystic category, followed closely by the inflammatory/reactive category and tumour/tumour-like category, respectively. The top ten most frequently encountered lesions in the present study were dentigerous cyst, mucocele, pyogenic granuloma, ameloblastoma, radicular cyst, odontoma, odontogenic keratocyst, irritation fibroma (focal fibrous hyperplasia), fibrous dysplasia, and osteomyelitis. The majority of lesions were found in the mixed dentition period (49.24%). There was no statistical difference in the occurrence between genders in this study. Conclusions., The present study shows an almost similar trend to previous studies except in the ranking among and within categories. These differences may be attributable to the nature of the population studied and because Chulalongkorn University is a major referral centre. [source] Prostate cancer in London: is the triadic clinical encounter the standard?INTERNATIONAL JOURNAL OF UROLOGICAL NURSING, Issue 2 2008Amanda Euesden Hughes Abstract It has been reported that men with prostate cancer in London were less satisfied with the service they received than patients with other cancers. Studies from the USA have looked at the experience of the prostate cancer couple. It has been established that the cancer couple have information needs and that when a clinical encounter is triadic in nature, these needs are more likely to be met and information is more likely to be retained. The aim of this study was to examine the clinic attendance patterns of men in London with prostate cancer (n = 200). A comparison group of women in London with breast cancer was identified (n = 200). Direct observation of the groups was performed, accompanied/unaccompanied (triadic/dyadic) attendance was recorded and demographic data were extracted from the clinical notes. Forty-one percent (81) of the women experienced their clinical encounter as a triad compared with 24% (48) of the prostate group who experienced their clinical encounter as a dyad between themselves and their health care provider (p < 0.05). In the first year of diagnosis, men with prostate cancer were more likely to experience a triadic encounter, but this was more evenly distributed throughout the cancer journey for women with breast cancer. There did not appear to be a correlation with marriage and triadic encounters for either group. Men with prostate cancer in this tertiary referral centre in London are less likely to experience a triadic clinical encounter than women with breast cancer. Further work is needed to establish a relationship between unmet informational needs of the prostate cancer couple and the high level of dissatisfaction in the prostate cancer population in London, but the nature of the dyadic encounter may play a part in this. [source] Methotrexate in paediatric ulcerative colitis: a retrospective survey at a single tertiary referral centreALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2010M. Aloi Aliment Pharmacol Ther 2010; 32: 1017,1022 Summary Background, Patients with ulcerative colitis often receive thiopurines as immunomodulators (IMs) to maintain remission and avoid corticosteroids. If unresponsive or intolerant to these agents, patients are treated with methotrexate, an antimetabolite never assessed in paediatric ulcerative colitis. Aim, To describe the experience with methotrexate in children with ulcerative colitis. Methods, Thirty-two patients (median age 13.9 years) received methotrexate. Pediatric Ulcerative Colitis Activity Index (PUCAI) and use of corticosteroids were the main outcomes evaluated at baseline and at 3, 6 and 12 months. Results, Indications to methotrexate were azathioprine unresponsiveness in 18 patients, azathioprine intolerance/toxicity in 10 and spondyloarthropathy in four. Response or remission was achieved in 72%, 63% and 50% of patients at 3, 6 and 12 months respectively. Mean PUCAI were 49.5 ± 23.3 at baseline and 32.9 ± 21.9, 29.5 ± 21.8 and 29.4 ± 19.9 at 3, 6 and 12 months respectively (P: 0.03). At the beginning of methotrexate, 16 patients (50%) received corticosteroids that were discontinued in 13 of them (81%) by 6 months. At the end of the study, 11 patients (33%) needed short courses of corticosteroids for disease relapse. Conclusions, Methotrexate may be useful in treating children with ulcerative colitis, although large, controlled trials are warranted to define better its effectiveness. [source] The anaesthetic management of patients with congenital insensitivity to pain with anhidrosisPEDIATRIC ANESTHESIA, Issue 4 2004V. Rozentsveig MD Summary Background :,Congenital insensitivity to pain with anhidrosis (CIPA, or hereditary sensory and autonomic neuropathy type IV) is a rare, autosomal recessive disease, related to a mutation in the TrkA gene, characterized by inability to sweat, insensitivity to pain and recurrent episodes of hyperpyrexia. There are two Bedouin tribes in Israel with different mutations of the TrkA gene: one in the southern region and the other in the northern region. The Soroka University Medical Center is the referral centre for the entire southern region of Israel. One in 4500 anaesthesia cases involves a patient with CIPA. Methods :,We reviewed 40 anaesthesia records of 20 patients with CIPA for anaesthetic technique and incidence of side-effects. Results :,Sixteen patients developed complications in the immediate perioperative period: mild hypothermia in one patient and cardiovascular events in 15 others with one case of cardiac arrest. These complications were unrelated to the anaesthetic drug administered. There were no events of hyperthermia or postoperative nausea. Conclusions :,Cardiovascular complications following anaesthesia are common in patients with the southern Israel variant of CIPA. Hyperthermia, previously recognized as a major concern in patients with congenital insensitivity to pain with anhydrous, was not seen in our patients. We conclude that cardiovascular involvement is frequently encountered in CIPA patients following anaesthesia and is the major concern in their anaesthetic management. [source] Structural heart defects associated with an increased nuchal translucency: 9 years experience in a referral centrePRENATAL DIAGNOSIS, Issue 4 2008S. A. Clur Abstract Objective To investigate the congenital heart disease (CHD) found in association with an increased nuchal translucency (NT) at 11,14 weeks of gestation in chromosomally normal and abnormal fetuses. Methods Patients referred from January 1998 until May 2007 with an increased NT (,95th percentile) where CHD was diagnosed were included. Chromosome analysis, fetal and postnatal echocardiography were performed. A postmortem examination followed pregnancy termination when possible. Results Major CHD was identified in 68 of 967 fetuses with an increased NT (median NT 4.8 mm, range 2.5,22 mm). Major CHD was found in 34 of 693 fetuses (4.9%) with a normal karyotype and increased NT (median 5.2 mm, range 2.5,9.6 mm). CHD frequency increased from 1.9%, with NT between 2.5 and 3.5 mm, to 27.7% when NT was , 6.5 mm. Septal defects predominated (20%) when NT was ,3.5 mm. With NT > 3.5 mm an equal distribution of CHD types was seen. Major CHD was identified in 34 of the 274 fetuses with an abnormal karyotype and increased NT (median 4.2 mm, range 2.5,22 mm). Conclusions A variety of CHD is associated with an increased NT in the first trimester of pregnancy. Conotruncal defects, branchial arch derivative defects, left and right obstructive lesions (inflow and outflow) and shunts were seen. Copyright © 2008 John Wiley & Sons, Ltd. [source] Use of inferior vena cava filters in a tertiary referral centre in AustraliaANZ JOURNAL OF SURGERY, Issue 5 2010Alok Tiwari Abstract Introduction:, To investigate the use of inferior vena cava (IVC) filters in a tertiary referral centre, looking at indication, types of filters and, with temporary/optional filters, removal rates. Methods:, Data was collected from a prospective database of all IVC filters inserted from January 2003 to January 2007. Patients' records and radiological imaging were all reviewed. Results:, 66 patients (40 males) had IVC filters inserted during the study period. The median age of the male patients was 57.5 (21,79) years, and females 56 (24,81). There were 49 (74.2%) temporary/optional filters and 17 (25.8%) permanent filters. The most common indication for filter was a contraindication to anticoagulation for both permanent (64.7%) and temporary/optional filters (77.6%). In the temporary/optional filter group, 38 of 49 (77.6%) patients had documented venous thromboembolism, while in the permanent filter group, this was 14 of 17 (82.4%). Of the optional filters, 22 of 49 (45.8%) have been removed. Conclusion:, More than half (54.2%) of temporary/optional filters were not removed and with potential for long-term complications. A protocol has now being instituted for vascular surgeons to authorize the insertion of filters and to then be responsible for ensuring their removal. [source] MINIMALLY INVASIVE PARATHYROIDECTOMY USING SURGEON-PERFORMED ULTRASOUND AND SESTAMIBIANZ JOURNAL OF SURGERY, Issue 9 2007Subhita Prasannan Background: Surgeon-performed ultrasound (SPU) and 99mTc-sestamibi (SM) scanning can be used alone or in combination in patients with primary hyperparathyroidism to select cases suitable for minimally invasive parathyroidectomy (MIP). The aim of the study was to evaluate SPU and SM and to determine the reliability they provide the surgeon in planning and carrying out MIP. Methods: The study was a prospective analysis of 130 patients with primary hyperparathyroidism who had preoperative localization with SPU and SM at a tertiary referral centre between 2003 and 2006. All ultrasound scans were carried out by one surgeon, followed by correlative sestamibi scan and a further ,on operating table' ultrasound to reassess the lesion and mark the operative site. Selection criteria for MIP were a positive SPU and SM, although a positive SPU or SM allowed the surgeon to focus on the nominated side. SPU and SM localizations were correlated to the operative findings. Results: One hundred and thirty patients underwent both SPU and SM. There were 97 women and 33 men, with a mean age of 59 years. SPU alone identified the abnormal parathyroid in 103 cases (sensitivity 82%; positive predictive value 96.3%). SM alone identified the abnormal gland in 102 cases (sensitivity 79%; positive predictive value 99%). In 88 patients, the SPU and SM were concordant, and 94% had successful MIP. SPU and SM were both negative in 13 patients, and all these patients had bilateral neck exploration. Conclusion: SPU in the hands of an experienced surgeon in association with sestamibi is a reliable tool for the preoperative localization of parathyroid adenomas and facilitates a minimally invasive procedure. [source] Epidemiological changes in colorectal cancer in Shiraz, Iran: 1980,2000ANZ JOURNAL OF SURGERY, Issue 7 2004Seyed Vahid Hosseini Background: The present study was performed to determine trends in colorectal cancer rates over the past two decades (1970,80 vs 1990,2000) with in a main referral centre in Shiraz, Iran. Methods: The Cancer Registry data on all colorectal cancer cases from 1970 to 2000 in Shiraz, Iran, were analysed. Demographic characteristics, clinical features, cancer site and type and stage of cancer were compared in the populations of two different decades. Results: The age-adjusted incidence of colorectal cancer per 100 000 population per year increased in men from a mean annual incidence of 1.61 in the decade 1970,80 to 4.2 in 1990,2000 (P < 0.05), and in women from 2.35 to 2.72 (P < 0.05). In 1970,80, patients over 60 years had 62.5% of all the colorectal cancers, which decreased to 30% in 1990,2000 (P < 0.05). The distribution of right and left sided cancers were almost equal and showed no significant difference between the two decades (P > 0.05). Conclusion: A marked increase in the incidence of colorectal cancer has been shown in Shiraz. Also, the marked increase in the incidence of colorectal cancer in the 40,60-year-old age group shown in the present study necessitates a more detailed work-up in younger age group patients. [source] Outpatient hysteroscopy: Factors influencing post-procedure acceptability in patients attending a tertiary referral centreAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 6 2009Kate MCILWAINE Background:, Ambulatory hysteroscopy is a safe, reliable and cost-effective alternative to hysteroscopy under a general anaesthetic for the diagnosis of abnormal uterine bleeding. Aim:, The objective of this study was to assess which factors influenced patients' willingness to attend for future outpatient hysteroscopy. The outpatient hysteroscopy service commenced at the Mercy Hospital for Women in 2000. It provides women with the opportunity to have the cause of abnormal uterine bleeding diagnosed in an outpatient setting. Methods:, A prospective audit was conducted of 283 women attending for outpatient hysteroscopy at the Mercy Hospital for Women over a period of almost five years (May 2003 through February 2008). Results:, Of the women audited, 88.7% stated that they would accept the procedure in future, whilst 11.3% would not. There was a significant difference between the two groups with respect to their median visual analogue pain scale (VAS) pain scores during the procedure (3.00 versus 6.50 P < 0.0001) with the higher score in the group who would not re-attend for the procedure. There was also a significant difference between the two groups with respect to the change in median VAS score from pain anticipated to pain experienced (0.00 versus 3.50 P = 0.0001). The rate of unsuccessful procedures was significantly higher (40.6% versus 0.8%P < 0.05) in future non-attendees as well as a higher rate of clinical vasovagal episodes (25% versus 5.2%P = 0.01) in women who stated that they would not re-attend for the procedure. Preprocedure analgesia and type of anaesthetic administered during the procedure did not seem to influence whether women would attend for outpatient hysteroscopy in future. Conclusions:, The acceptability rate for women attending for outpatient hysteroscopy during the audit period was 88.7%. Pain was a significant determinant of procedure acceptability; however, the acceptability rate was not influenced by analgesia or type of anaesthetic administered. [source] Aetiology and prevalence of lower limb lymphoedema following treatment for gynaecological cancerAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2003Mary Ryan Abstract Objective: To determine the prevalence and incidence of lower limb lymphoedema (LLL) in a cohort of women who had treatment for gynaecological cancer between May 1995 and April 2000. Design: A retrospective survey. Setting: The study took place at an urban referral centre in an Australian tertiary referral women's hospital. Sample: The data collection was based on 66% of 743 women on the database of the Gynaecological Cancer Centre. Methods: Interviews and assessments were conducted to determine the status of lower limbs; medical records were reviewed for age, weight, site and type of cancer and treatment. Main outcome measures: Leg swelling, diagnosed lower limb lymphoedema, no swelling of the legs and type of surgery were determined as the main outcome measures. Results and conclusions: The diagnosis of lower limb lymphoedema was made in 18% of the total sample: 53% of these were diagnosed within 3 months of treatment, a further 18% within 6 months, 13% within 12 months and the remaining 16% up to 5 years following treatment. Women most at risk for developing LLL were those who had treatment for vulvar cancer with removal of lymph nodes and follow up radiotherapy. For this subsample, the prevalence was 47%. The finding that LLL occurs within the first year is earlier than hitherto generally believed. It is therefore imperative for all health professionals to include care and assessment of the legs particularly during the immediate pre- and postoperative period. [source] Caecal intussusceptions in horses: a New Zealand perspectiveAUSTRALIAN VETERINARY JOURNAL, Issue 7 2010RJW Bell Objective To establish the prevalence of intussusceptions involving the caecum in a population of horses admitted to a university hospital for colic. Design Retrospective clinical study Methods Medical records of all horses admitted to the Massey University Veterinary Teaching Hospital between 1991 and 2004 were examined for information of those horses diagnosed with an intussusception involving the caecum. Results A total of 135 horses were admitted for colic surgery during the study period and 61 horses had a diagnosis of ileocaecal (37), caecocaecal (5) or caecocolic intussusception (19) made either at surgery or necropsy. Of the horses with ileocaecal intussusception, 32 had an incomplete hand-sewn ileocaecostomy without reduction and 29 survived to discharge. All the horses with caecocaecal intussusceptions were diagnosed preoperatively via rectal examination and/or transabdominal ultrasound: 2 were euthanased at surgery and 3 survived to discharge. In the 19 horses with caecocolic intussusceptions, manually reduction at surgery was performed in 6 and 5 of them survived to discharge. A typhlectomy was performed via a colotomy in 6 horses, 3 of which survived to discharge. Conclusions The high prevalence of intussusceptions involving the caecum seen at this referral centre may indicate a higher prevalence in New Zealand than is reported elsewhere in the world. Clinical relevance Intussusceptions involving the caecum should be considered as a differential diagnosis in horses presenting with chronic low-grade colic. Transabdominal ultrasound is useful for identifying caecocaecal and caecocolic intussusceptions. Hand-sewn side-to-side incomplete ileocaecostomy is a quick, effective and safe method of surgical treatment of ileocaecal intussusceptions.

Design Urine was collected from 50 dog and 25 cats presented for investigation and treatment of diseases unrelated to snake envenomation. Urine was collected as a voided sample, by cystocentesis or by catheterisation, and routine urinanalysis was performed. Snake venom testing was performed within 2 h of collection using a commercially available snake venom detection kit, which was observed continuously during the 10-min colour reaction phase for evidence of a visible colour indicating a positive test. Results No false-positive reactions occurred in any sample analysed. Conclusion The snake venom detection kit appears to have 100% specificity for using urine as a test sample.

Appropriate antenatal corticosteroid use in women at risk for preterm birth before 34 weeks of gestation. BJOG 2010;117:963,967. Objective, To determine the utilisation of antenatal corticosteroid administration in women presenting at risk of preterm birth (PTB) in a centre where tocolytics are not prescribed. Design, A prospective cohort study. Setting, Tertiary referral centre, Dublin, Ireland. Population, Four hundred and fourteen consecutive women presenting at risk of PTB. Methods, Clinical details were collated prospectively on all booked patients who presented at risk of PTB (i.e. at <34 weeks of gestation) during 2008. Main outcome measure, Rate of administration of antenatal corticosteroids in PTB. Results, Of 8985 deliveries, 414 women (5%) presented at <34 weeks of gestation with a clinical potential for PTB, of whom 277 (67%) received antenatal corticosteroids. Amongst women delivering at <34 weeks of gestation, 93% (80/86) received any corticosteroids and 76% (65/86) received a complete course. The ratio of women given a complete course of corticosteroids to the number who actually delivered before 34 weeks of gestation was 4:1 overall. Analysis by indication for PTB revealed this ratio to be 15:1 in suspected preterm labour (PTL), 8:1 in antepartum haemorrhage (APH), and 2:1 in both preterm prelabour rupture of membranes (PPROM) and medically indicated PTB (MIPTB). Seven of ten multiparae (70%) who delivered prematurely during the study period following PTL had a history of previous PTL before 34 weeks of gestation. Conclusion, The ratio of maternal antenatal corticosteroid administration for potential versus actual PTB at <34 weeks of gestation was high in categories such as PTL and substantial APH, whereas selection in PPROM and MIPTB approached 100%. There should be a low threshold for single course therapy for women with prior PTL before 34 weeks of gestation. [source] Different profiles of circulating angiogenic factors and adipocytokines between early- and late-onset pre-eclampsiaBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2010H Masuyama Please cite this paper as: Masuyama H, Segawa T, Sumida Y, Masumoto A, Inoue S, Akahori Y, Hiramatsu Y. Different profiles of circulating angiogenic factors and adipocytokines between early- and late-onset pre-eclampsia. BJOG 2010;117:314,320. Objective, Circulating angiogenic factors have been shown to be important in the pathophysiology of pre-eclampsia. Blood levels of adipocytokines differ in pre-eclampsia relative to controls and may also play an important role in disease pathogenesis. Differences in the circulating levels of these molecules were compared between matched normotensive controls and women with pre-eclampsia with onset before or at/after 32 weeks, and according to whether the women were of normal weight (18.5 < body mass index < 25) or overweight. Design, A cross-sectional study of 110 pregnant Japanese women who visited the Department of Obstetrics and Gynecology, Okayama University Hospital, Okayama, Japan. Setting, Tertiary referral centre serving 2000 births. Methods, Serum concentrations of soluble fms-like tyrosine kinase 1 (sFlt-1), placental growth factor (PlGF), soluble endoglin (sEng), adiponectin and leptin were measured in women with pre-eclampsia and in normotensive controls matched for age, gestational week, parity and body mass index. Main outcome measures, Serum levels of sFlt-1, PlGF, the sFlt-1/PlGF ratio, sEng, adiponectin and leptin. Results, The sFlt-1/PlGF ratio in early-onset pre-eclampsia was significantly higher than that in late-onset pre-eclampsia (112.0 ± 30.2 versus 45.4 ± 43.8, P = 0.037). There was a significant elevation of leptin in both subtypes relative to controls (early: 58.6 ± 18.3 ng/ml versus 26.0 ± 6.7 ng/ml, P = 0.001; late: 39.5 ± 9.2 ng/ml versus 22.0 ± 4.3 ng/ml, P = 0.005), but adiponectin was increased only in late-onset pre-eclampsia (36.5 ± 13.4 ,g/ml versus 12.0 ± 4.3 ,g/ml, P = 0.003). Significant differences in angiogenic factors and adiponectin were found between normal and overweight women only in late-onset pre-eclampsia. Conclusions, These data suggest that there are different profiles of angiogenic factors and adipocytokines between women who develop early- and late-onset pre-eclampsia. [source] ,Blood On The Tracks' from corpora lutea to endometriomas,BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2009P Vercellini Objective, To detect a direct transition from a haemorrhagic corpus luteum to an endometriotic cyst by serial transvaginal ultrasonographic scans. Design, Prospective observational study. Setting, An academic tertiary care and referral centre for women with endometriosis. Population, One hundred and nine women younger than 40 years, with regular menstrual cycles, undergoing first-line surgery for endometriomas, and not wanting postoperative oral contraception. Methods, Three-monthly transvaginal ultrasonography during the luteal phase for 2 years after surgery. Main outcome measure, Sonographic identification of progression from a haemorrhagic corpus luteum to a recurrent endometriotic cyst. Results, A haemorrhagic corpus luteum was identified in 13 women. Serial ultrasonographic scans demonstrated transition to an endometriotic cyst in 11 (85%) instances and resorption in two. A unilateral endometriotic cyst without previous detection of a cystic corpus luteum was observed in 14 women. Conclusions, Bleeding from a corpus luteum appears to be a critical event in the development of endometriomas. [source] In vivo magnetic resonance spectroscopy of gynaecological tumours at 3.0 TeslaBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2009SJ Booth Background, Magnetic resonance spectroscopy (MRS) uses the same hardware as MR imaging and allows us to analyse the biochemistry of tissues in vivo. Published data for gynaecological lesions are limited and are largely based on MRS carried out at the lower magnetic field strength of 1.5 Tesla (T). Objective, The purpose of this study was to determine whether in vivo proton MRS could be performed at the higher magnetic field strength of 3 T to characterise the spectra of a variety of benign and malignant gynaecological lesions. Design, Prospective, non-randomised study. Setting, MRI department within a tertiary referral centre for gynaecological cancers. Sample, All women with a pelvic mass under going 3T MRI. Methods, We carried out MRS on nonrandomised women undergoing routine 3 T MRI within our MRI department during investigation for gynaecological lesions from February 2006 to April 2008. Only those women for whom histopathological data were available were included. Main outcome measures, The presence of choline detected by in vivo 3T MRS. Results, Eighty-seven women underwent MRS, 57 of whom had newly diagnosed neoplasms. MRS data for 39 of these new women (18 were excluded because of technical errors or missing data) were used to detect the presence of choline, an indicator of basement membrane turnover. Overall, choline was present in 13 of the 14 ovarian cancers, 8 of the 11 cervical tumours and all 4 of the uterine cancers. There was no statistical significant difference between choline levels in various lesion types (P= 0.735) or between benign and malignant disease (P= 0.550). Conclusions,In vivo MRS can be performed at 3 T to provide biochemical information on pelvic lesions. The way in which this information can be utilised is less clear but may be incorporated into monitoring tissue response in cancer treatments. [source] Early onset severe pre-eclampsia: expectant management at a secondary hospital in close association with a tertiary institutionBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2005Charl Oettle Objectives Early onset severe pre-eclampsia is ideally managed in a tertiary setting. We investigated the possibility of safe management at secondary level, in close co-operation with the tertiary centre. Design Prospective case series over 39 months. Setting Secondary referral centre. Population All women (n= 131) between 24 and 34 weeks of gestation with severe pre-eclampsia, where both mother and fetus were otherwise stable. Methods After admission, frequent intensive but non-invasive monitoring of mother and fetus was performed. Women were delivered on achieving 34 weeks, or if fetal distress or major maternal complications developed. Transfer to the tertiary centre was individualised. Main outcome measures Prolongation of gestation, maternal complications, perinatal outcome and number of tertiary referrals. Results Most women [n= 116 (88.5%)] were managed entirely at the secondary hospital. Major maternal complications occurred in 44 (33.6%) cases with placental abruption (22.9%) the most common. One maternal death occurred and two women required intensive care admission. A mean of 11.6 days was gained before delivery with the mean delivery gestation being 31.8 weeks. The most frequent reason for delivery was fetal distress (55.2%). There were four intrauterine deaths. The perinatal mortality rate (,1000 g) was 44.4/1000, and the early neonatal mortality rate (,500 g) was 30.5/1000. Conclusions The maternal and perinatal outcomes are comparable to those achieved by other tertiary units. This model of expectant management of early onset, severe pre-eclampsia is encouraging but requires close co-operation between secondary and tertiary institutions. Referrals to the tertiary centre were optimised, reducing their workload and costs, and patients were managed closer to their communities. [source] Total laparoscopic hysterectomy as a primary surgical treatment for endometrial cancer in morbidly obese womenBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2005C.K.H. Yu To evaluate the feasibility of total laparoscopic hysterectomy as the primary treatment for endometrial cancer in morbidly obese women, an audit was carried out during an 18-month period in a tertiary referral centre for gynaecological oncology. Four women who had laparoscopic surgery were compared with a similar cohort who had open surgery. The mean operating time was equivalent, without evidence of excess morbidity with the laparoscopic approach. However, inpatient stay was longer with open versus laparoscopic surgery (11.5 vs 4 days). Laparoscopic surgery is safe to use in morbidly obese women with endometrial cancer. [source] | ||||||||||||||||||||||||||||||||||
