Trends in compliance with the national colposcopy guidelines.

This study aims to assess trends in compliance with current colposcopy guidelines in 10 gynaecological units in four English counties since 1996; to identify constraints on compliance and suggest change in practice. All 10 gynaecology units in Oxfordshire, Buckinghamshire, Northamptonshire and Berkshire participated. Data were collected prospectively by colposcopists from 23,500 new referrals across a 55-month period from September 1996 to March 2001. The Oxford Cancer Intelligence Unit performed collation, quality assurance and retrieval of data for incomplete records. Audit results were disseminated annually to colposcopists via the Regional Colposcopy Group. Colposcopy waiting times exceeded the standards, but waiting times for high-grade referrals showed statistically significant improvement. Six standards were achieved; relating to accuracy, appropriateness of management and outcomes. The seven unmet standards relate to waiting times, colposcopist's caseload, follow-up policy and the proportion of cervical epithelial neoplasia (CIN) on histology. Changes in practice are suggested, constraints on compliance are identified and the appropriateness of some guidelines is questioned.     

Electroconvulsive therapy and the alpha-2 noradrenergic receptor: implications of treatment schedule effects

Six factorially designed studies evaluated the effects of different schedules of electroconvulsive shocks (ECSs) on alpha-2 adrenoceptor function in the rat brain. Attenuation of the hypomotility response to a clonidine challenge was taken to indicate alpha-2 adrenoceptor downregulation, a putative mediator of antidepressant action. Six daily and six alternate-day ECSs were shown separately to produce this receptor change. Three alternate-day ECSs produced comparable downregulation for a comparable period as six daily ECSs; this suggests that ECS produces time-dependent effects. No changes were elicited with a single ECS, which indicates that a single ECS may not influence alpha-2 receptor function. Three daily ECSs produced brief downregulation, which has implications for receptor dynamics as a function of the ECS schedule. Finally, maintenance ECSs sustained alpha-2 adrenoceptor downregulation over 6 weeks, which suggests a possible neurochemical basis for maintenance electroconvulsive therapy. The clinical relevance and scope for further research are discussed.     

Nonalcoholic Fatty Liver Disease after Liver Transplant

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease in the world. The rising prevalence of nonalcoholic steatohepatitis (NASH) has led to a 170% increase in NASH cirrhosis as the listing indication for liver transplantation from 2004 to 2013. As of 2018, NASH has overtaken hepatitis C as an indication for liver transplantation in the USA. After liver transplantation, the allograft often develops recurrent NAFLD among patients with known NASH cirrhosis. In addition to recurrent disease, de novo NAFLD has been reported in patients with other indications for liver transplantation. In this review, we will discuss the risk factors associated with recurrent and de novo NAFLD, natural course of the disease, and management strategies after liver transplantation.     

An analysis of the clinical profile of patients with uveitis following COVID-19 infection

Purpose:To describe the clinical profile of patients presenting with uveitis following COVID-19 infection at a tertiary care eye hospital in South India.Methods:In this retrospective chart review, all consecutive cases presenting with an acute episode of intraocular inflammation and a history of COVID-19 infection diagnosed within the preceding 6 weeks, between March 2020 and September 2021, were included. Data retrieved and analyzed included age, sex, laterality of uveitis, and site of inflammation. The diagnosis was categorized based on the SUN working group classification criteria for uveitis. Details regarding clinical features, investigations, ophthalmic treatment given, response to treatment, ocular complications, and status at last visit were also accessed. Statistical analysis of demographical data was done using Microsoft Excel 2019.Results:Twenty-one eyes of 13 patients were included in this hospital-based retrospective observational study. The study included six male and seven female patients. The mean age was 38 ± 16.8 years. Eight patients had bilateral involvement. Seven patients were diagnosed with anterior uveitis, three with intermediate uveitis, one with posterior uveitis, and two with panuveitis. All patients responded well to treatment and were doing well at their last visit. Two patients had complications that necessitated surgical treatment, following which they recovered good visual outcomes.Conclusion:With prompt diagnosis and appropriate management, all the patients with uveitis post-COVID-19 infection recovered with good visual outcomes. Thus, ophthalmologists must be aware of the possible uveitic manifestations following even uneventful COVID-19 infection.     

Role of tissue harmonic imaging in focal hepatic lesions: comparison with conventional sonography

Background: The purpose of the present study was to compare iissue harmonic imaging (THI) and conventional sonography in focal hepatic lesions. Methods: Fifty patients with focal hepatic lesions were enrolled for study. Conventional grayscale and THI was performed in all the patients and two sets of images of the lesions were recorded (one each for THI and conventional) and assessed for fluid–solid differentiation, detail and overall image quality. These images were compared with conventional sonographic images and graded better, same or worse as per the case. Lesions were confirmed by fine‐needle aspiration cytology (FNAC)/surgery/other modalities such as computed tomography (CT) or magnetic resonance imaging (MRI). Results: Out of 50 patients with focal hepatic lesions, 21 patients had metastatic lesions (two single; 19 multiple) five patients had hepatocellular carcinoma (HCC), five patients had hydatid cysts, nine had simple hepatic cyst whereas five patients had liver abscess, three had focal fatty infiltration; and lymphoma and hemangioma were seen in one patient each. The first observer ranked THI better than standard sonography in 40 patients (80%) for fluid–solid differentiation, in 38 (76%) for detail and in 39 (78%) for overall image quality. The second observer ranked THI better than standard sonography in 39 patients (78%) for fluid–solid differentiation, in 40 (80%) for detail and in 42 (84%) for overall image quality. Tissue harmonic imaging provided additional information in eight patients (16%) and resulted in treatment alteration in three patients (6%). Conclusion: Tissue harmonic imaging was significantly better than conventional sonography for fluid–solid differentiation, detail and total image quality in focal hepatic lesions, especially in obese patients and patients with poor acoustic window.     

Does Physicians’ Case Volume Impact Inpatient Care Costs for Pneumonia Cases?

Summary Background Increasing physician case volumes are documented to reduce costs and improve outcomes for many surgical procedures but not for medical conditions such as pneumonia that consume significant health care resources. Objective This study explored the association between physicians’ inpatient pneumonia case volume and cost per discharge. Design The design was a retrospective, population-based, cross-sectional study, using National Health Insurance administrative claims data. Setting The setting was Taiwan. Participants The participants were a universal sample of 270,002 adult, acute pneumonia hospitalizations, during 2002–2004, excluding transferred cases and readmissions. Measurements Hierarchical linear regression modeling was used to examine the association of physician’s volume (three volume groups, designed to classify patients into approximately equal sized groups) with cost, adjusting for hospital random effects, case severity, physician demographics and specialty, hospital characteristics, and geographic location. Results Mean cost was NT$2,255 (US$1 = NT$33 in 2004) for low-volume physicians (≤100 cases) and NT$1,707 for high-volume physicians (≥316 cases). The adjusted patient costs for low-volume physicians were higher (US$264 and US$235 than high- and medium-volume physicians, respectively; both P < .001), with no difference between high- and medium-volume physicians. High-volume physicians had lower in-hospital mortality and 14-day readmission rates than low-volume physicians. Conclusions Data support an inverse volume–cost relationship for pneumonia care. Decision processes and clinical care of high-volume physicians versus low-volume physicians should be studied to develop effective care algorithms to improve pneumonia outcomes and reduce costs.
