Kinds of Referral Hospital Selected AbstractsDiaphragmatic hernia in horses: 44 cases (1986,2006)JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 4 2009Samantha K. Hart BVMS (Hons) Abstract Objectives , To present a case series of horses diagnosed with diaphragmatic hernia, and to determine the significance of (1) historical information, examination findings, and laboratory data; and (2) exploratory laparotomy or necropsy findings on short- and long-term outcome. Setting , University Referral Hospital. Design , Retrospective study. Animals , Forty-four horses/foals admitted between 1986 and 2006 with a diagnosis of diaphragmatic hernia made either at exploratory laparotomy or necropsy. Interventions , None. Measurements and Main Results , Information from the medical records included history, clinical examination findings at presentation, and findings of exploratory laparotomy or necropsy. Logistic regression or the Fisher exact test was used to determine factors associated with survival. Outcome was defined as survival to discharge (short-term survival), and long-term survival was defined as horses alive at least 1-year post surgery. Of the 44 horses, 18 died or were euthanized before surgery. Twenty-six were taken to surgery, 17 were euthanized. Nine horses recovered from anesthesia, 7 of which survived to hospital discharge. Of these, 5 were alive at long-term follow-up. Survival was significantly associated with the age of the horse (,2 y old) at presentation, presence of normal peritoneal fluid at presentation, amount of compromised viscera at surgery (<50% small intestine), and the size (<10 cm) and location (ventral) of the diaphragmatic tear. Conclusion , This study confirms that size and location of the lesion do play a significant role in prognosis. And, although the prognosis for horses with diaphragmatic hernia is poor, if horses have operable lesions there is a fair prognosis for long-term survival. [source] Evaluating the use of plasma hematocrit samples to detect ketones utilizing urine dipstick colorimetric methodology in diabetic dogs and catsJOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 1 2003Mark A. Brady DVM Abstract Objective: To determine whether plasma from a heparinized hematocrit tube placed on a urine dipstick would accurately reflect (positive or negative) urine ketone results in diabetic dogs and cats. Design: Prospective study, 37 dogs and 43 cats, with a known history of diabetes or hyperglycemia, glucosuria, and symptoms of undiagnosed diabetes mellitus were tested. Setting: Veterinary Referral Hospital. Animals: Client owned dogs and cats. Interventions: None. Measurement and main results: Heparinized plasma and urine ketone results were recorded using urine reagent strips. Plasma dipstick results were compared to urine dipstick results as the standard. Results were recorded based on the color chart provided by the manufacturer. Two individuals were responsible for verifying the results of the colorimetric test. Test efficiency was 97% (sensitivity = 96%, specificity = 100%) for the canine population, 93% (sensitivity = 100%, specificity = 83%) for the feline population, and 95% (sensitivity = 98%, specificity = 91%) for the total population. Four of 80 animals were found to have discordant results (1 dog and 3 cats). Conclusion: Plasma from heparinized hematocrit tubes is clinically useful for detecting the presence or absence of ketonuria, and therefore ketosis, in diabetic dogs and cats using urine dipstick colorimetric methodology. [source] Coconut palm-related injuries in the pacific islandsANZ JOURNAL OF SURGERY, Issue 1 2001J. S. Mulford Introduction: Coconut palms are an integral part of life in the Solomon Islands, given the widespread dependence of subsistence agriculture. Injuries related to the coconut palm are thus inevitable. Hospital records from the Central Referral Hospital were reviewed to identify (i) how commonly the coconut palm is implicated in injuries referred to the surgery department; (ii) which patients are being injured; and (iii) the type of injuries sustained. Methods: The present study reviews all patients referred to the Department of Surgery and Orthopaedics between January 1994 and December 1999 who had a coconut palm-related injury. This was possible due to the trauma epidemiology form, which records the patient details, cause of injury, fracture details and other injury information. Results: A total of 3.4% of all injuries presenting to the surgical department was related to the coconut palm. Eighty-five patients fell from the coconut palm, 16 patients had a coconut fruit fall on them, three patients had a coconut palm fall on them and one patient kicked a coconut palm. The majority of patients who were injured by falling from a coconut palm were young (aged 6,25 years). Eleven of the 16 patients struck by falling fruit were under 25 years of age. The majority of injuries sustained were fractures. Patients falling from coconut palms sustained mainly upper limb fractures (60.1% of all fractures) or spinal fractures (16.3%). Patients injured by falling fruit sustained skull or upper limb fractures. All skull fractures occurred in patients under the age of 10 years. Conclusion: This is the largest review of coconut palm-related injuries. It highlights some epidemiological facts that raise considerations for preventative health measures in the Solomon Islands. Parents and young children must be warned of the dangers of playing beneath coconut trees. Boy and girls should be warned of the dangers of collecting fruit. With an increasing amount of schooling becoming available the Solomon Islands is an ideal place to direct an education programme about the dangers of coconut palms as well as many other primary health issues. Because subsistence farming plays a crucial role in the life of most Solomon Islanders, injuries that result in loss of function are crippling both to the patient and the village. Any preventative measure to reduce the rates of injury will be important. [source] Spurious hypercreatininemia: 28 neonatal foals (2000,2008)JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 2 2010DACVECC, DACVIM, Kristin P. Chaney DVM Abstract Objectives , To (1) determine the occurrence of spurious hypercreatininemia in a population of hospitalized foals <2 days old, (2) assess the resolution of the hypercreatininemia, and (3) determine its association with survival in these foals. Design , Retrospective case series. Setting , 2 Referral hospitals. Animals , Foals <2 days old with an admission creatinine >442 ,mol/L (>5.0 mg/dL) from 2 referral hospitals. Interventions , None. Measurements and Main Results , The medical records of 33 foals were reviewed. Twenty-eight had spurious hypercreatininemia and 5 had acute renal failure. Admission creatinine was not significantly different between the 2 groups (mean [standard deviation]). The creatinine was 1,202 ,mol/L (663 ,mol/L) (13.6 mg/dL [7.5 mg/dL]) versus 1,185 ,mol/L (787 ,mol/L) (13.4 mg/dL [8.9 mg/d]) (P=0.96) in each group, respectively, though BUN at the time of hospital admission was significantly higher for acute renal failure foals (P=0.009). In the spurious group, serum creatinine at admission decreased to 504 ,mol/L (380 ,mol/L) (5.7 mg/dL [4.3 mg/dL]) by 24 hours, and to 159 ,mol/L (80 ,mol/L) (1.8 mg/dL [0.9 mg/dL]) at 48 hours, and to 115 ,mol/L (44 ,mol/L) (1.3 mg/dL [0.5 mg/dL]) at 72 hours. Twenty-three of 28 foals with spurious hypercreatininemia survived to hospital discharge and there was no difference in mean admission creatinine between survivors (1176 ,mol/L [628 ,mol/L]) (13.3 mg/dL [7.1 mg/dL]) and nonsurvivors (1308 ,mol/L [857 ,mol/L]) (14.8 mg/dL [9.7 mg/dL]) (P=0.67). Twenty of 28 foals had clinical signs suggestive of neonatal encephalopathy. Conclusion , Creatinine decreased by >50% within the initial 24 hours of standard neonatal therapy and was within the reference interval in all but 1 foal within 72 hours of hospitalization. The diagnosis of neonatal encephalopathy was common in these foals. [source] Response to first-line antiretroviral treatment among human immunodeficiency virus-infected patients with and without a history of injecting drug use in IndonesiaADDICTION, Issue 6 2010Rudi Wisaksana ABSTRACT Background There is a common belief that injecting drug use (IDU) is associated with lower uptake, retention and success of antiretroviral treatment (ART) in human immunodeficiency virus (HIV)-infected patients. We examined this in an Indonesian setting, where IDU is the main risk factor for HIV infection. Methods Patient characteristics and response to ART were recorded for all patients diagnosed with HIV infection in the referral hospital for West Java (40 million people). Kaplan,Meier estimates and Cox's regression were used to compare mortality, loss to follow-up and virological failure between patients with and without a history of IDU. Result A total of 773 adult HIV patients (81.9% IDUs) presented between January 1996 and April 2008. IDUs had a median CD4 cell count of 33 [interquartile ratio (IQR), 12,111] cells/mm3 compared to 84 (IQR, 28,224) cells/mm3 in non-IDUs. Among patients with a history of IDU, 87.7% were coinfected with hepatitis C (HCV). Mortality was associated strongly with CD4 count; after 6 months of ART, 18.3, 20.3, 7.1 and 0.7% of patients with CD4 cell counts <25, 25,99, 100,199, respectively, ,200/mm3 had died (P < 0.0001). Mortality [adjusted for CD4; hazard ratio (HR) = 0.65; 95% confidence interval (CI) 0.35,1.23], loss to follow-up (HR = 0.85, 95% CI 0.51,1.41) and virological failure (HR = 0.47, 95% CI 0.19,1.13) were not significantly different in IDUs and non-IDUs. Conclusion Intravenous drug users (IDUs) in Indonesia with HIV/acquired immune deficiency syndrome tend to have more advanced disease but respond similarly to non-IDUs to antiretroviral therapy. [source] Multidisciplinary assessment at triage: A new way forwardEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2004Joanna R Richardson Abstract Objective:, To evaluate a dual doctor and nurse triage system at a tertiary referral hospital. Methods:, Data were compared between periods of multidisciplinary triage and periods of standard triage. Data comparison was also made between rostered multidisciplinary triage shifts and non-multidisciplinary triage shifts. Staff satisfaction with the process was assessed. Results:, The percentage of patients seen within Australasian Triage Scale performance indicator thresholds increased from 75% to 81% in Category 2 patients (P = 0.12) and 56% to 78% in Category 3 patients (P < 0.0001). There was a reduction of 50% in the number of patients who left prior to being seen by a doctor (P = 0.024). Surveys showed high staff satisfaction with the process. Conclusions:, We feel that multidisciplinary triage performs a useful function in our department enabling us to reduce waiting times. The process is widely accepted amongst the staff and it ensures a senior doctor assesses most patients. It reduces the number of patients leaving prior to being seen by a doctor and it provides one way of getting around access block and a physically small department. [source] The prevalence of lipodystrophy in an ambulant HIV-infected population: it all depends on the definitionHIV MEDICINE, Issue 3 2001VM Carter Objectives This study's objective was to determine the prevalence of body shape changes and metabolic abnormalities in an ambulant population with HIV infection. Three different definitions of lipodystrophy were used to assess these changes. Patients' anthropometric measures and dual-energy X-ray absorptiometry (DEXA) scans were compared in order to estimate fat distribution in this population. We sought to evaluate potential predictors for lipodystrophy according to each of the three definitions. Methods We performed a cross-sectional study in the outpatient clinic of a tertiary referral hospital in Melbourne, Australia. We enrolled a total of 167 HIV-infected ambulatory patients over 3 months in mid-1998. Data on 159 males, 149 of whom were receiving triple combination antiretroviral therapy, were evaluated. Anthropometric measures, clinical examination, self-report of body shape changes, biochemical measures and DEXA scan were used to assess lipodystrophy and risk factors for cardiovascular disease. Patients described body shape changes in the face, trunk, arms and legs. Laboratory parameters measured included fasting triglyceride (TG), cholesterol, high-density lipoproteins (HDL), glucose, insulin, CD4 cell count and plasma HIV RNA. Current and past antiretroviral therapies were ascertained. Results According to one proposed Australian national definition of lipodystrophy (LDNC), the prevalence of lipodystrophy in this population was 65%. This definition included an objective assessment with major and minor criteria. Patient-defined lipodystrophy (LDP), which involved a subjective assessment of thinning arms and legs and central adiposity, occurred in 19%. Patient-defined lipoatrophy (LAP), which involved a subjective assessment of thinning arms and legs without central adiposity, occurred in 21.3%. No change in body habitus was noted by 37% of the cohort. Hypercholesterolaemia was recorded in 44%, hypertriglyceridaemia in 52% and elevated insulin levels in 23%. Anthropometry was predictive of the per cent total body fat recorded by DEXA scan, but produced consistently lower values. In multivariate analysis, LDP and LAP were significantly associated with stavudine (d4T) use, while LAP was also associated with zidovudine (ZDV) treatment. There were no treatment associations with LDNC. Protease inhibitor (PI) exposure was associated with metabolic changes but not patient perceived body shape changes, while d4T and ZDV exposure was associated with increased triglycerides and reduced peripheral fat stores. Conclusions The prevalence of body shape changes in a single population varied depending on the definition applied. The LDNC definition overestimated body shape abnormalities in comparison with patient perception. LAP was associated with significantly lower fat stores measured by anthropometry and DEXA scan than those identified under the LDNC definition. In contrast to LDNC, LAP was associated with d4T exposure, nucleoside reverse transcriptase inhibitor (NRTI) and ZDV duration of use, but not PI use. Until a consensus definition for lipodystrophy is developed, including agreement on objective measurement and thresholds for abnormality, careful description of the individual components of the syndrome is required to enable cohort comparisons so that predictors of the syndrome can be assessed more accurately and outcome studies made feasible. [source] Establishing an action research group to explore family-focused nursing in the intensive care unitINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 1 2007Fiona Coyer RN ENB100 PGCEA PhD This paper presents the first phase of a four-phase collaborative action research study which aimed to facilitate family-focused nursing in the intensive care environment. The purpose of phase one was to determine intensive care nurses' perceptions of family-focused critical care nursing and the appropriateness of family-focused nursing in the intensive care unit. A collaborative action research group was established with six registered nurses working in the intensive care unit of a metropolitan tertiary referral hospital. Data were collected through group discussions and analysed using open coding. Findings revealed two categories related to perceptions of family-focused intensive care nursing: partnership in care and maintaining a balance. The group unanimously agreed that family-focused nursing was appropriate in the intensive care environment. The three subsequent action research phases of this study are reported elsewhere. [source] No-Reflow Phenomenon Following Percutaneous Coronary Intervention for Acute Myocardial Infarction: Incidence, Outcome, and Effect of Pharmacologic TherapyJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2010F.A.C.C., F.A.C.P., SHEREIF H. REZKALLA M.D. Background: No-reflow (NR) phenomenon is a well-known problem, often accompanying percutaneous coronary intervention for acute ST elevation myocardial infarction (STEMI). There are little data on effects of pharmacologic therapy on the resolution, outcome, and long-term natural history of NR. Objective: Retrospectively assess incidence, management, and prognosis of NR in a tertiary referral hospital. Methods: Study included patients with STEMI, treated with percutaneous coronary intervention (PCI). Effect of pharmacologic therapy and long-term outcome were assessed. NR was defined by thrombolysis in myocardial infarction (TIMI) < 3 or myocardial blush grade (MBG) < 3. Results: Of 347 identified subjects, NR occurred in 110 (32%) by TIMI and 198 (57%) by MBG. Higher incidence was identified in men versus women (34% vs. 25% by TIMI, P = 0.08; and 60% vs. 48% by MBG, P = 0.04). Pharmacologic therapy was equally effective in restoring normal flow, increasing TIMI score from 1.62 ± 0.07 to 2.78 ± 0.06 (P < 0.0001) and MBG score from 0.43 ± 0.08 to 2.09 ± 0.11 (P < 0.0001). Twenty-three percent who did not receive pharmacologic therapy developed clinical composite of congestive heart failure, cardiogenic shock, and/or death; only 9% of patients who received pharmacologic therapy developed this composite. Patients with severe NR despite treatment had poorer prognosis. Sixty-five percent of patients who survived and had repeat angiogram about 1.5 years later had spontaneous improvement in coronary flow by MBG. Conclusion: NR is common in STEMI. Treatment with nicardipine, nitroprusside, and verapamil are equally effective in improving flow. If not treated, prognosis is poor.

The goal of this study was to examine the incidence, consequences, and the treatment of arterial access dissections at a tertiary referral hospital with an active training program. Methods: Patients experiencing arterial access dissection during coronary angiography or intervention at our institution between October 1, 2004, and January 31, 2007, were identified and their records were retrospectively reviewed. Results: Thirteen of the 3,062 consecutive patients (0.42%) had arterial access dissection during the study period. The location of the dissection was in the common femoral artery (CFA) (n = 6), the external iliac artery (EIA) (n = 6), or in an aortobifemoral graft (n = 1). Three of the six patients with CFA dissection were diagnosed during coronary angiography, and because of significant comorbidities were treated with self-expanding stents. After a mean follow-up of 7 months, they experienced no stent fracture or other complication. Six patients had EIA dissections. In one such patient, the dissection was not flow limiting and was treated conservatively. The remaining five patients underwent successful implantation of self-expanding stents, and during a mean follow-up of 9.6 months, no patient had any symptoms or events related to lower extremity ischemia. Finally, one patient had an aortobifemoral graft dissection. Due to the patient's critical condition, secondary to sepsis, his family elected to withdraw care, and he subsequently expired. Conclusions: Arterial access dissections occur infrequently during cardiac catheterization. Routine femoral artery angiography may help identify vascular access complications, often allowing simultaneous endovascular treatment, with excellent short-term outcomes. [source] Visual inspection with acetic acid test qualities in a secondary settingJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2008Bandit Chumworathayi Abstract Aim:, To evaluate the visual inspection using acetic acid (VIA) test qualities in a secondary (follow-up) setting, 1 year after cryotherapy treatment performed as part of the Safety, Acceptability and Feasibility demonstration project designed to evaluate the safety, acceptability and feasibility of VIA. An immediate offer of cryotherapy was made to those who test positive and are eligible for treatment. Methods:, At 1 year after cryotherapy, 648 women received both a secondary (follow-up) VIA test by nurse-providers, and colposcopy with biopsy, if indicated, by trained physician colposcopists at a referral hospital. All pathologic specimens were sent for examination by a single pathologist. Results:, VIA nurse-providers assessed 42 of the 648 women (6.5%) referred as abnormal (i.e. they tested positive or were suspected of having cancer). Among the 42, the final colposcopic-based diagnosis was HSIL or higher in three cases (7.1%), of which two were HSIL and one was adenocarcinoma. Of the 606 VIA negative women, the colposcopic-based diagnosis was HSIL in only two cases (0.3%). Conclusions:, The VIA test qualities in this setting were: a positive rate of 6.5%, a sensitivity of 60%, a specificity of 93.9%, a positive predictive value of 7.1%, a negative predictive value of 99.7% and an accuracy of 93.7%. These results are comparable to those of Pap smear in most settings. [source] Characteristics of antepartum and intrapartum eclampsia in the National Maternal and Child Health Center in CambodiaJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 2 2004Kanal Koum Abstract Aim:, To measure maternal and perinatal outcome and analyze risk factors for antepartum and intrapartum eclampsia, which is one of main causes of high maternal mortality at the top referral hospital in the Kingdom of Cambodia. Methods:, A hospital-based retrospective study of 164 antepartum and intrapartum eclampsia cases out of 20 449 deliveries. Results:, Overall case,fatality rate was 12%. Rate of stillbirth and low birth weight were 20% and 44%, respectively. Eighty percent of the cases presented signs of severe pre-eclampsia and 27% of the patients who gave birth received cesarean section. Living outside the capital city, teenage pregnancy and twin pregnancy are more frequently associated with eclampsia. Conclusion:, Antepartum and intrapartum eclampsia is associated with severe pre-eclampsia and with poor maternal and perinatal outcome. Recommendations to reduce the burden of eclampsia are promoting and improving quality of antenatal care and health education especially in the third trimester; increasing access to high-quality essential obstetric care; improving the service delivery in rural areas; and monitoring the progress by hospital data.

[source] Meticillin-resistant Staphylococcus aureus in a veterinary orthopaedic referral hospital: staff nasal colonisation and incidence of clinical casesJOURNAL OF SMALL ANIMAL PRACTICE, Issue 4 2008C. L. McLean Objectives: To evaluate staff nasal colonisation with meticillin-resistant Staphylococcus aureus in a veterinary orthopaedic referral hospital, and its effect on the occurrence of meticillin-resistant Staphylococcus aureus -associated postoperative wound complications in orthopaedic and spinal surgical patients. Methods: Nasal bacterial swabs were collected from veterinary staff and environmental surfaces swabbed at six monthly intervals for meticillin-resistant Staphylococcus aureus monitoring over an 18 month period. The incidence of meticillin-resistant Staphylococcus aureus -associated postoperative wound complications of two veterinary orthopaedic surgeons was reviewed for a period when one was positive for nasal meticillin-resistant Staphylococcus aureus. Results: Meticillin-resistant Staphylococcus aureus was isolated from a maximum of two out of 10 staff on each occasion. The persistently infected clinician was primary surgeon in 180 cases, of which four developed meticillin-resistant Staphylococcus aureus -associated wound complications. None of 141 operations led by the other surgeon developed meticillin-resistant Staphylococcus aureus -associated complications. This difference is not statistically significant (P=0·0974). The 95 per cent confidence interval for this odds ratio was 0·83 to 44·0. Meticillin-resistant Staphylococcus aureus resistance patterns of the human nasal isolates and three of four wound-associated isolates were similar. Clinical Significance: Veterinary workers are at increased risk for meticillin-resistant Staphylococcus aureus colonisation, so it is likely that many veterinary patients are treated by meticillin-resistant Staphylococcus aureus -positive staff. Nasal colonisation of veterinary surgeons with meticillin-resistant Staphylococcus aureus appears to present only a small risk to their patients when appropriate infection control procedures are followed. [source] Therapeutic hypothermia after out-of-hospital cardiac arrest: experiences with patients treated with percutaneous coronary intervention and cardiogenic shockACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2007J. Hovdenes Background:, Therapeutic hypothermia has been shown to increase survival after out-of-hospital cardiac arrest (OHCA). The trials documenting such benefit excluded patients with cardiogenic shock and only a few patients were treated with percutaneous coronary intervention prior to admission to an intensive care unit (ICU). We use therapeutic hypothermia whenever cardiac arrest patients do not wake up immediately after return of spontaneous circulation. Methods:, This paper reports the outcome of 50 OHCA patients with ventricular fibrillation admitted to a tertiary referral hospital for immediate coronary angiography and percutaneous coronary intervention when indicated. Patients were treated with intra-aortic balloon counterpulsation (IABP) (23 of 50 patients) if indicated. All patients who were still comatose were treated with therapeutic hypothermia at 32,34 °C for 24 h before rewarming. The end-points were survival and cerebral performance category (CPC: 1, best; 5, dead) after 6 months. Results:, Forty-one patients (82%) survived until 6 months. Thirty-four patients (68%) were in CPC 1 or 2, and seven (14%) were in CPC 3. Of the 23 patients treated with IABP, 14 (61%) survived with CPC 1 or 2. In patients not treated with IABP, 20 patients (74%) survived with CPC 1 or 2. Forty patients (80%) developed myocardial infarction. Percutaneous coronary intervention was performed in 36 patients (72%). Conclusion:, In OHCA survivors who reached our hospital, the survival rate was high and the neurological outcome acceptable. Our results indicate that the use of therapeutic hypothermia is justified even in haemodynamically unstable patients and those treated with percutaneous coronary intervention. [source] Clinical features and natural history of acquired cold urticaria in a tertiary referral hospital: a 10-year prospective studyJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 12 2008A Katsarou-Katsari Abstract Background, Acquired cold urticaria (ACU) represents a heterogeneous group of disorders that share a common clinical feature: the development of urticaria or angioedema after cold exposure. We present epidemiological and clinical data of subjects with ACU, natural progression and we examine possible parameters that could correlate with disease severity. Methods, During a 10-year period in all subjects with ACU, detailed record of personal history, laboratory testing, cold stimulation testing (CST), atopy assessment and disease severity took place. In a re-evaluation visit at the end of the surveillance period, ACU progression was assessed from patients in a subjective way. Results, Four thousand one hundred fifty-seven individuals with chronic urticaria were referred, and 352 (198 males, 154 females, 8.47% of patients with chronic urticaria) presented definite symptoms of physical urticarias, while 95 individuals (49 males, 46 females, 27% of patients with physical urticarias) were detected with ACU. Sixty-two participants were included in study analysis. Thirty-two patients (51.6%) were female; the mean age was 41.5 ± 15.6 years, while the mean age at disease onset was 32.5 ± 15.6 years; half were , 30 years old at disease onset. The mean duration of surveillance was 9.0 ± 6.9 years. During this time interval, 18 patients (29.0%) showed the same or even worse symptomatology, 26 patients reported some improvement (41.9%), while in 18 patients, symptoms resolved completely (29.0%); the mean time to resolution was 5.6 ± 3.5 years. Disease severity was the only variable statistically significantly related to disease progression (P = 0.004). Conclusions, Cold urticaria is a chronic persistent disorder with occasional severe clinical manifestations. [source] Emergency case admissions at a large animal tertiary university referral hospital during a 12-month periodJOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 3 2008Brett A. Dolente VMD, DACVIM Abstract Objective: To collate and describe emergency admissions to a large animal tertiary university referral hospital during a 12-month period. Design: Prospective clinical study. Setting: Large animal tertiary university referral hospital. Animals: Large animal emergency patient admissions. Interventions: None. Measurements and main results: Information obtained from the medical record included the presenting complaint, clinical problem, admission time, duration of clinical signs before presentation, diagnostic procedures performed, therapies administered, and therapeutic procedures performed during the first 24 hours following admission, and survival to discharge. The most common category listed for the presenting complaint and clinical problem categories was gastrointestinal. Most emergency cases were admitted during the evening and in late spring, summer, and early fall. Most cases had a duration of clinical signs before presentation of >2 hours and ,8 hours (27%) or >8 hours and ,24 hours (29%). The most common diagnostic procedures performed during the first 24 hours were palpation per rectum, ultrasonographic examination, radiographs, and abdominocentesis. Antimicrobials, fluids, and nonsteroidal anti-inflammatory drugs were the most common therapies administered. Approximately 25% of cases required surgery. An exploratory celiotomy was performed in approximately 15% of cases. Enterotomy, intestinal resection and anastomosis, cesarean section, or joint or sheath lavage was each performed in <5% of cases. Overall survival to discharge was 74%. Conclusions: Large animal emergency clinicians are required to have knowledge on a wide range of diseases and should be proficient at performing numerous procedures on an emergency basis. Gastrointestinal disease is the most common type of emergency and the diagnostic and therapeutic procedures performed during the first 24 hours following admission are a reflection of this type of case. Only 25% of cases required surgery. Additional research in the form of a multicenter study and surveying both private and university practitioners needs to be performed to further define the necessary skills for an ,ideal' large animal emergency clinician. [source] Descending thoracic aortic blood flow parameters during emergent surgery in anesthetized critically ill dogsJOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 4 2002Richard J. Mills DVM Abstract Objective: To explore the potential value of transesophageally-determined descending thoracic aortic blood flow parameters in critically ill dogs undergoing surgery. Design: Observational case series. Setting: Private small animal referral hospital. Animals: Ten anesthetized critically ill dogs that underwent emergent surgery. Interventions: Placement of the ultrasonic transesophageal probe. Measurements and main results: Transesophageally-determined descending thoracic aortic blood flow, stroke volume, blood velocity, blood acceleration, left ventricular ejection time interval, and heart rate parameters were recorded every minute. Systolic and mean arterial blood pressures were non-invasively determined and recorded at 1,5 minute intervals. The anesthetist and surgeon were blinded to the descending thoracic aortic blood flow parameters. All dogs received fluid challenges as part of their management, and 2 dogs received dopamine. The variability of the descending thoracic aortic blood flow parameters within each dog was greater than has been reported in non-critically ill anesthetized dogs. Consistent trends in descending thoracic aortic blood flow parameters after fluid challenges were not found. An escalating dopamine infusion was, however, accompanied by increasing aortic blood flow, stroke volume, acceleration, and peak velocity. Conclusions: Descending thoracic aortic blood flow parameters may eventually be useful for evaluating the responses to and suggesting the need for cardiovascular interventions during emergent surgeries in anesthetized critically ill canine patients. For this to occur, more experience with this technology will be required. [source] A Retrospective Study of the Incidence and the Classification of Bone Marrow Disorders in the Dog at a Veterinary Teaching Hospital (1996,2004)JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 4 2006Douglas J. Weiss Background: An 8-year retrospective study was conducted to evaluate the prevalence and the classification of canine bone marrow disorders in a clinical pathology service at a university referral hospital. Animals: Dogs evaluated for bone marrow disorders at a veterinary teaching hospital. Hypothesis: A better understanding of the spectrum and the prevalence of canine bone marrow disorders can be achieved with a multiyear retrospective study. Methods: Bone marrow aspirate smears, core biopsy specimens, and case records from 717 dogs were reviewed. Results: Bone marrow specimens were first categorized based on the presence or the absence of a primary bone marrow disorder. Nondysplastic and nonmalignant pathologic changes were placed into 14 subcategories. Frequently observed pathologic disorders included nonregenerative immune-mediated anemia, pure red cell aplasia, bone marrow necrosis, myelofibrosis, and hemophagocytic syndrome. Dysmyelopoiesis (n = 61) was subcategorized into myelodysplastic syndromes (n = 27), and congenital (n = 1) and secondary (n = 33) dysmyelopoiesis. One hundred twenty-six cases of neoplasia were divided into acute leukemia (n = 46), chronic leukemia (n = 7), stage 5 malignant lymphoma (n = 28), multiple myeloma (n = 25), malignant histiocytosis (n = 11), metastatic mast-cell tumor (n = 3), sarcoma (n = 5), and carcinoma (n = 1). Conclusions and Clinical Importance: This study provides a general indication of the spectrum and the prevalence of canine bone marrow disorders at a referral center in North America. [source] Small bowel polyps and tumours: endoscopic detection and treatment by double-balloon enteroscopyALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2009L. C. FRY Summary Background, Double-balloon enteroscopy has allowed us not only to inspect deeply the small bowel but also to carry out interventions for diseases of the small bowel. Aim, To evaluate the utility of double-balloon enteroscopy for the diagnosis and therapy of these lesions. Methods, All patients undergoing double-balloon enteroscopy for evaluation of small bowel polyps and tumours during a 3.75-year period at a university referral hospital were studied. The types of polyps and tumours as well as endoscopic technique of removal, surgery and complications were documented. Results, The incidence of small bowel polyps and tumours in-patients undergoing DBE was 9.6%. A total of 40 double-balloon enteroscopy procedures were performed in 29 patients [13 female (44.8%), mean age 51 years, range 22,74]. The following lesions were found most frequently: adenomas in familial adenomatous polyposis syndrome, n = 8; hamartomas, n = 4 (Peutz-Jeghers and Cronkhite Canada syndromes), jejunal adenocarcinoma n = 5, neuroendocrine tumour n = 4 and others n = 6. Conclusions, The incidence of small bowel tumours in those in-patients who were undergoing double-balloon enteroscopy was 10%. Double-balloon enteroscopy is useful for the diagnosis and treatment of small bowel polyps and tumours. [source] Classic pyomyositis of the extremities as an unusual manifestation of Blastomyces dermatitidis: a report of two casesMYCOSES, Issue 4 2010Michael Y. Lin Summary Pyomyositis is an infection of skeletal muscle that, by definition, arises intramuscularly rather than secondarily from adjacent infection. It is usually associated with bacterial infection, particularly Staphylcococcus aureus. Fungi are rare causes, and Blastomyces dermatitidis has not been reported previously. In this case series, we report two cases of pyomyositis caused by B. dermatitidis. Cases were prospectively identified through routine clinical care at a single academic referral hospital. Two patients with complaints of muscle pain and subacute cough were treated at our hospital in 2007. Both patients were found to have pyomyositis caused by B. dermatitidis, in the quadriceps muscles in one patient, and in the calf muscle in another , by radiological imaging and fungal culture. Both were also diagnosed with pneumonia caused by B. dermatitidis (presumptive in one, confirmed in the other). There was no evidence of infection of adjacent structures, suggesting that the route of infection was likely direct haematogenous seeding of the muscle. A review of the literature confirmed that although B. dermatitidis has been described as causing axial muscle infection secondary to adjacent infection such as vertebral osteomyelitis, our description of isolated muscle involvement (classic pyomyositis) caused by B. dermatitidis, particularly of the extremity muscles, is unique. We conclude that B. dermatitidis is a potential cause of classic pyomyositis. [source] Iron and vitamin deficiencies, endocrine and immune status in patients with primary Sjögren's syndromeORAL DISEASES, Issue 3 2001IMC Lundström OBJECTIVES: To study the prevalence of iron and vitamin deficiencies, endocrine disorders and immunological parameters in patients with primary Sjögren's syndrome (1°SS). DESIGN AND SUBJECTS: At the time of the establishment of the diagnosis of 1°SS in 43 consecutive patients, a clinical examination including haematological analyses was performed. The patients' medical records were also reviewed. SETTING: Patients referred for diagnosis to The University Hospital, Linköping, a secondary or tertiary referral hospital serving the middle part of southern Sweden. RESULTS: In total, current or previously treated iron and vitamin deficiencies were registered for 63% of the 1°SS patients (iron 51%, vitamin B12 25%, folate 9%). Current low ferritin was noted in 24%, low iron saturation in 37%, decreased vitamin B12 in 13% and folate in 9%. Thyroid disease was found in a total of 33% and 30% had had autoimmune thyroiditis. Three patients (7%) had verified diabetes mellitus. Erythrocyte sedimentation rate (ESR) was raised in 65% of the patients and 84% had a polyclonal increase of Ig. Rheumatoid factor (RF) was detected in 85%, antinuclear antibody (ANA) in 74%, anti-SS-A in 88% and anti-SS-B in 73% of the patients. CONCLUSION: Iron and vitamin deficiencies and thyroid diseases are common in patients with 1°SS. Since these disorders often are treatable and may affect the patients' distress as well as their immune and exocrine function, an active, recurrent search for deficiencies, endocrine diseases and other frequently recorded disorders is recommended. [source] Clinicopathological study of bronchogenic carcinomaRESPIROLOGY, Issue 4 2004Rajendra PRASAD Objective: The present study was undertaken to explore the clinicopathological profile of bronchogenic carcinoma. Methodology: Four hundred consecutive patients with histopathologically proven bronchogenic carcinoma, hospitalized between 1985 and 1999 at a large teaching and tertiary care referral hospital at King George's Medical University in Lucknow, India, were analysed. Results: The average age of the bronchogenic carcinoma patients was 57 years; 9.8% of patients were less than 40 years of age; the ratio of male to female patients was 4.3:1.0; 71% were smokers; and 87% of the smoking patients were bidi smokers. The most common histological type was squamous-cell carcinoma (46.5%), followed by adenocarcinoma (18.5%) and small-cell carcinoma (18.2%). The majority of patients (74.2%) were diagnosed in the late stages of the disease (IIIb and IV). Conclusion: Bidi smoking is an important contributory factor in the development of bronchogenic carcinoma in India, and approximately 25% of patients with bronchogenic carcinoma are non-smokers. [source] A prospective evaluation of hemoptysis cases in a tertiary referral hospitalTHE CLINICAL RESPIRATORY JOURNAL, Issue 3 2010uz Uzun Abstract Background and Aims:, Hemoptysis is symptomatic of a potentially serious and life-threatening thoracic disease. The purpose of this study was to evaluate the relative frequency of the different causes of hemoptysis, the change of the frequency of diseases, the value of the evaluation process and the outcome in a tertiary referral hospital. Methods:, A prospective study was carried out on consecutive patients presented with hemoptysis. Results:, A total of 178 patients (136 male, 42 female) were included to the study. Lung cancer (51), pulmonary embolism (23) and bronchiectasis (23) constituted most of the diagnosis. The most frequent cause of hemoptysis in males was by far lung carcinoma (50). Twelve cases of bronchiectasis and 11 cases of pulmonary embolism were observed in females. While lung cancer and pulmonary embolism were associated with mild to moderate amounts of bleeding (84% and 100%, respectively), patients with active tuberculosis and pulmonary vasculitis had severe to massive hemoptysis (50% and 44%, respectively). Transthoracic and other organ biopsies, spiral computed tomography (CT) angiography (X pres/GX model TSX-002a, Toshiba, Tochigi Ken, Japan) and aortography yielded high diagnostic results in our group (100%, 67%, 59% and 100%, respectively). The most frequent final diagnosis in patients with normal chest radiograph was pulmonary embolism (seven cases). Conclusions:, Lung cancer, pulmonary embolism and bronchiectasis were the main causes of hemoptysis in this prospective cohort; however, this is the first report showing pulmonary embolism as a leading cause of hemoptysis. CT angiography with high-resolution CT should be the primary diagnostic modality if the initial investigation is inconclusive in hemoptysis cases.

[source] No Effect of a Nasal Decongestant on Eustachian Tube Function in Children With Ventilation Tubes,THE LARYNGOSCOPE, Issue 6 2002Niels van Heerbeek MD Abstract Objective The aim of the study was to assess the effect of a topical decongestant on eustachian tube function in children with ventilation tubes because of persistent otitis media with effusion. Study Design A randomized, double-blinded, placebo-controlled study. Methods At the outpatient departments of a secondary referral hospital and a tertiary referral hospital, eustachian tube function was measured before and after intranasal administration of five drops of 0.05% xylometazoline hydrochloride or placebo in 80 randomly selected children with ventilation tubes because of otitis media with effusion. Results Xylometazoline nose drops had no effect on the ventilatory or the protective function of the eustachian tube. Conclusions Topical decongestants do not have a positive effect on eustachian tube function in children. Therefore, the use of topical decongestants to prevent or treat otitis media with effusion in children is not justified and should be discouraged. [source] A prospective study of the effect of nursing home residency on mortality following hip fractureANZ JOURNAL OF SURGERY, Issue 6 2010Ian A. Harris Abstract Background:, The strength of nursing home residence as a prognostic indicator of outcome following hip fracture has not previously been examined in Australia. The aim of the study was to examine the influence of nursing home residency on mortality after sustaining an acute hip fracture. Methods:, A prospective study of all adults aged 65 years and over presenting to a single tertiary referral hospital for management of a proximal femoral fracture between July 2003 and September 2006. Residential status was obtained at admission. Patients were followed up to September 2007 (minimum 12 months). Relative risk values for mortality were calculated comparing nursing home residents with non-nursing home residents. Survival analysis was performed. Results:, Relative risk of death was higher in nursing home patients compared with non-nursing home patients. The difference was greater in the immediate period (30 days) post-injury (relative risk 1.9, 95% confidence interval 1.0,3.6, P= 0.04) than after 12 months (relative risk 1.5, 95% confidence interval 1.2,1.8, P= 0.001). Survival analysis showed that 25% of patients in the nursing home group died by 96 days post-injury, compared with 435 days in the non-nursing home group. Conclusions:, Nursing home residence confers an increased risk of death following hip fracture; this difference is greater in the immediate post-injury period. The relative risk of death decreases over time to equal previously reported comparative mortality rates between nursing home residents and community dwellers without hip fracture. [source] POST CAESAREAN VESICOUTERINE FISTULAE , YOUSSEF SYNDROME: OUR EXPERIENCE AND REVIEW OF PUBLISHED WORKANZ JOURNAL OF SURGERY, Issue 4 2006M. Prasad Rao Objective: To analyse the incidence, symptomatology, diagnosis and therapeutic aspects of Youssef syndrome (post caesarean vesicouterine fistula), and to review relevant published work. Methods: A retrospective study from the urosurgical unit of a tertiary care referral hospital was carried out. In a retrospective analysis of urogenital fistulae over 10 years, we identified 14 patients with uterovesical fistulae, resulting from caesarean section. All the patients were evaluated by history, physical examination, radiological tests and cystoscopy. All patients underwent transperitoneal repair of these fistulae with omental interposition. Results of surgery were evaluated by absence of cyclic haematuria, stoppage of urinary incontinence, and achievement of fertility. Results: A total of 12 patients who had minimum follow up was included in the present study. The results showed that 50% of the fistulae resulted from emergency caesarean operation with 58% of patients presenting after their second caesarean section. The mean age of the patients was 19 years (range 15,29) and mean duration of symptoms was 7 months (range 3,16). Menouria and amenorrhoea were predominant presenting symptoms. The results of surgical treatment were excellent with good continence and resolution of the cyclic haematuria. Three pregnancies (37.5%) which resulted in elective caesarean section were recorded. Conclusion: Vesicouterine fistulae, despite being infrequent, are no longer a rare diagnosis and are most commonly secondary to lower segment caesarean section. With patient history and selected investigations diagnosis is relatively easy. The surgical repair of these fistulae is standard treatment, especially with delayed fistulae with achievement of total continence, and complete resolution of cyclic haematuria. Meticulous practice of obstetric and surgical principles during caesarean section can prevent the formation of these fistulae. [source] Cryotherapy as the treatment modality of postcoital bleeding: A randomised clinical trial of efficacy and safetyAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 5 2009Grace Wing Shan KONG Background:, Postcoital bleeding is a common gynaecological problem that impacts on a woman's quality of life and sexual function. There is little systematic research into its management. Aims:, To assess the efficacy and side-effects of cryotherapy as treatment for postcoital bleeding. Methods:, A prospective randomised controlled trial was conducted in a tertiary referral hospital in Hong Kong. A total of 85 women who presented with postcoital bleeding were recruited, and randomised to cryotherapy or no treatment. The treatment group received cryotherapy with compressed carbon dioxide through a cryoprobe placed on the cervix, and controls had cryoprobe on the cervix without compressed carbon dioxide flow. All recruited women were followed up two weeks, three months and six months to review their symptoms and response to the treatment. Results:, The treatment group had a significantly better long-term cure rate and improvement rate. At six months, the cryotherapy group reported a cure rate of 72.1% while that in the control group the cure rate was 50.0% (P = 0.04). The number needed to treat was 5. The mean improvement rate of the cryotherapy group was 82.88% ± 35.87 but was only 61.62% ± 55.30 in the control group (P = 0.04). The results were more significant in women with the defined pathological cervix. Apart from the vaginal discharge at second week follow up in the treatment group, there was no statistical significant difference in side-effects and complications among two groups. Conclusion:, Our study demonstrated that cryotherapy is a safe and an effective treatment for postcoital bleeding. [source] Medical and midwifery students: how do they view their respective roles on the labour ward?AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 4 2002Julie A Quinlivan ABSTRACT Background It has been suggested that much of the medical and midwifery student curricula on normal pregnancy and birth could be taught as a co-operative effort between obstetric and midwifery staff. One important element of a successful combined teaching strategy would involve a determination of the extent to which the students themselves identify common learning objectives. Aim The aim of the present study was to survey medical and midwifery students about how they perceived their respective learning roles on the delivery suite. Methods A descriptive cross-sectional survey study was undertaken. The study venue was an Australian teaching and tertiary referral hospital in obstetrics and gynaecology. Survey participants were medical students who had just completed a 10 week clinical attachment in obstetrics and gynaecology during the 5th year of a six year undergraduate medical curriculum and midwifery students undertaking a one year full-time (or two year part-time) postgraduate diploma in midwifery. Results Of 130 and 52 questionnaires distributed to medical and midwifery students, response rates of 72% and 52% were achieved respectively. The key finding was that students reported a lesser role for their professional colleagues than they identified for themselves. Some medical students lacked an understanding of the role of midwives as 8%, 10%, and 23% did not feel that student midwives should observe or perform a normal birth or neonatal assessment respectively. Of equal concern, 7%, 22%, 26% and 85% of student midwives did not identify a role for medical students to observe or perform a normal birth, neonatal assessment or provide advice on breastfeeding respectively. Summary Medical and midwifery students are placed in a competitive framework and some students may not understand the complementary role of their future colleagues. Interdisciplinary teaching may facilitate co-operation between the professions and improve working relationships. [source] Availability of antidotes for the treatment of acute poisoning in Queensland public hospitalsAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 2 2010Lisa M. Nissen Abstract Objective:,To determine the sufficiency of stock levels of 13 antidotes in Queensland hospitals. Design:,A self-report survey was sent to 128 Queensland hospitals with acute care facilities. The stock level of the following antidotes was determined: acetylcysteine, anti-digoxin Fab antibodies (digibind), atropine, calcium gluconate, cyanokit, desferrioxamine, flumazenil, glucagon, intravenous ethanol, methylene blue, naloxone, pralidoxime and pyridoxine. Other factors sampled were bed capacity, rural, remote and metropolitan areas classification, use of formal stock reviews by pharmacists or nurses, existence of formal borrowing agreements with other facilities for non-stocked antidotes, distance to the nearest referral hospital and time taken to transfer antidotes from another hospital. Participants:,Pharmacists or nurses responsible for maintaining antidote stocks in Queensland hospitals. Main outcome measures:,Proportions of hospitals with sufficient antidote stock to treat a 70-kg adult for four or more hours using previously published guidelines. Results:,Survey response rate was 73.4%. No hospital had sufficient stock of all 13 antidotes. The proportion of hospitals with sufficient stocks varied from 0% (pyridoxine) to 68.1% (acetylcysteine). Larger hospitals had a higher frequency of sufficient antidote stocks. Only 16% of hospitals claimed to be able to acquire an antidote from another facility within 30 min. Conclusions:,Most Queensland hospitals stocked some important antidotes, but few had sufficient stock to treat a 70-kg patient or acquire an antidote within the recommended time frame of 30 min. Specific antidote stocking guidelines might be required for Queensland hospitals. A formalised program for stock rotation with rural facilities should be explored.
