Interpretation of World Health Organization growth charts for assessing infant malnutrition: a randomised controlled trial.

AIMS: The study aims to assess the effects of switching from National Center for Health Statistics (NCHS) growth references to World Health Organization (WHO) growth standards on health-care workers' decisions about malnutrition in infants aged <6 months. METHODS: We conducted a single blind randomised crossover trial involving 78 health-care workers (doctors, clinical officers, health service assistants) in Southern Malawi. Participants were offered hypothetical clinical scenarios with the same infant plotted on NCHS-based weight-for-age charts and again on WHO-based charts. Additional scenarios compared growth charts with a single final weight against charts with the same final weight plus a preceding growth trend. Reported (i) level of concern, (ii) referral suggestions and (iii) feeding advice were elicited with a questionnaire. RESULTS: Even after adjusting for health-care worker type and experience, using WHO rather than NCHS charts increased: (i) concern: aOR 4.4 (95% CI 2.4-8.1); (ii) odds of referral: aOR 5.1 (95% CI 2.4-10.8); and (iii) odds of feeding advice which would interrupt exclusive breastfeeding (aOR 2.4, 95% CI 1.2-4.9). A preceding steady growth trend line did not affect concern, referral or feeding advice. CONCLUSIONS: Health-care workers take insufficient account of linear growth trend, clinical and feeding status when interpreting a low weight-for-age plot. Because more infants <6 months fall below low centile lines on WHO growth charts, their use may increase inappropriate referrals and risks undermining already low rates of exclusive breastfeeding. To avoid their being misinterpreted in this way, WHO charts need accompanying guidelines and training materials that recognise and address this possible adverse effect.

Matching physicians' treatment recommendations to patients' treatment preferences is associated with improvement in treatment satisfaction.

BACKGROUND: Dissatisfaction with treatment is common among those with psoriasis. While incorporating patients' preferences into the process of treatment decision-making may improve satisfaction, this relationship has not been clearly established. OBJECTIVE: To assess the extent to which matching physicians' treatment recommendations to patients' treatment preferences is associated with improvement in treatment satisfaction in patients with moderate-to-severe psoriasis. METHODS: This prospective cohort study design examined change from baseline to 3-month follow-up in four subscales of an established measure of treatment satisfaction. Separate multivariate regression models investigated the association of change in these subscale scores with an index measuring the match between physicians' treatment recommendations and patients' treatment preferences at the initial study visit. RESULTS: A closer match between physicians' recommendations and patients' preferences was associated with greater improvement in treatment satisfaction over time in each of the four subscales: effectiveness (ß = 0.53, P < 0.001), side-effects (ß = 0.25, P = 0.009), convenience (ß = 0.78, P < 0.001) and global satisfaction (ß = 0.49, P < 0.001). Adjusted models explained as much as 76% of the variation in change in treatment satisfaction subscales over 3 months. CONCLUSIONS: Further efforts to incorporate patients' preferences in treatment decision-making appear justified given the strength of independent associations between preference matching and improved treatment satisfaction and the extent to which our models explained variation in this relationship. An approach based on preference matching shows promise for increasing satisfaction in the management of other chronic diseases.

Patient preferences for psoriasis treatments: impact of treatment experience.

BACKGROUND: Patient preferences for psoriasis treatments can impact treatment satisfaction and adherence and may therefore influence clinical outcome. OBJECTIVE: To assess the impact of treatment experience (satisfaction with current treatment, number of prior visits, disease duration, number of preceding therapies and currently prescribed treatment modalities) on treatment preferences. METHODS: A computer-based conjoint analysis experiment was conducted to analyse preferences of patients with moderate or severe psoriasis (n = 163) treated at a German University Medical Center for outcome (probability, magnitude and duration of benefit; probability, severity and reversibility of side effects) and process attributes (location, frequency, duration, delivery method, individual cost) of psoriasis treatments. Relative importance scores (RIS) were calculated for each attribute and compared using anova, post hoc test and multivariate regression analysis. RESULTS: Participants with longer disease duration attached significantly greater importance to duration of benefit (ß = 0.206, P = 0.018), whereas participants on oral therapy were more concerned about magnitude of benefit by trend (ß = 0.218, P = 0.058). Participants receiving injectables not only set higher value to probability of benefit (RIS = 32.80 vs. 21.89, P = 0.025) but also to treatment location (RIS = 44.74 vs. 23.03, P = 0.011), delivery method (RIS = 43.75 vs. 19.29, P = 0.019), treatment frequency (RIS = 31.24 vs. 16.89, P = 0.005) and duration (RIS = 32.54 vs. 16.57, P = 0.003) when compared with others. Treatment satisfaction was significantly higher in participants on infusions or injections compared with those on phototherapy and mere topical therapy. CONCLUSIONS: Treatment preferences may change over time course and with treatment experience. Participants on injectables attach great importance to efficiency and convenience of therapies, and are highly satisfied with their treatment.

Formative Objective Structured Clinical Examinations (OSCEs) as an Assessment Tool in UK Undergraduate Medical Education: A Review of Its Utility.

The Objective Structured Clinical Examination (OSCE) is a globally established clinical examination; it is often considered the gold standard in evaluating clinical competence within medicine and other healthcare professionals' educations alike. The OSCE consists of a circuit of multiple stations testing a multitude of clinical competencies expected of undergraduate students at certain levels throughout training. Despite its widespread use, the evidence regarding formative renditions of the examination in medical training is highly variable; thus, its suitability as an assessment has been challenged for various reasons. Classically, Van Der Vleuten's formula of utility has been adopted in the appraisal of assessment methods as means of testing, including the OSCE. This review aims to provide a comprehensive overview of the literature surrounding the formative use of OSCEs in undergraduate medical training, whilst specifically focusing on the constituents of the equation and means of mitigating factors that compromise its objectivity.

INFERIOR VENA CAVA FILTER PLACEMENT FOR PREVENTION OF PULMONARY THROMBOEMBOLISM: CASE SERIES FROM NORTHWESTERN NIGERIA.

Background: Inferior vena cava (IVC) filter placement is an image-guided procedure aimed at primarily preventing pulmonary thromboembolism in patients with lower limb venous thromboembolic (VTE) disease. In Northern Nigeria with a relatively high incidence of thromboembolic disease such as Deep vein thrombosis, reports on IVC filter placement are largely low. We report the feasibility of IVC filter placement on eight patients for the first time in a typical low-resource setting in Northern Nigeria. Case Presentations: We had an equal number of males and females of the eight patients. Their ages ranged from 20 to 80 years. Five patients presented with bilateral lower limbs Deep vein thrombosis (DVT) of which one had a pulmonary embolism. Two other patients had extensive left femoral DVT and one had extensive IVC, iliac, femoral, and popliteal veins thrombosis. The medical records of seven patients, who had IVC filter placement in our department, were reviewed. The IVC filter was deployed with the aid of a C-arm fluoroscopic unit. In a single case, access was secured via an indwelling dialysis catheter. Conclusions: All the patients had successful deployment with satisfactory postprocedure conditions. The intended benefit of pulmonary embolism prevention was achieved in the series of procedures that were performed. Indicating the value of IVC filter even in resource-poor settings and effort should be made towards exploring such intervention.

Exploring the Role of Urocortin in Osteoporosis.

Osteoporosis is a debilitating disease that affects over 200 million people worldwide. Overactive osteoclast activity leads to micro-architectural defects and low bone mass. This culminates in fragility fractures, such as femoral neck fractures. Treatments currently available either are not completely effective or have considerable side effects; thus, there is a need for more effective treatments. The urocortin (Ucn) family, composed of urocortin 1 (Ucn1), urocortin 2 (Ucn2), urocortin 3 (Ucn3), corticotropin-releasing factor (CRF) and corticotropin-releasing factor-binding protein (CRF-BP), exerts a wide range of effects throughout the body. Ucn1 has been shown to inhibit murine osteoclast activity. This review article will aim to bridge the gap between existing knowledge of Ucn and whether it can affect human osteoclasts.

Evaluating the Usage of Musculoskeletal Spinal Drop-In Services in East Lancashire: A Retrospective Audit of Performance Standards.

Lower back pain (LBP) is a prevalent musculoskeletal disorder (MSD) that places a significant burden on patients as well as healthcare and economic systems. Musculoskeletal (MSK) spinal drop-in clinics in the North West of the United Kingdom (UK) have been introduced to provide more targeted therapies for those suffering from LBP. A retrospective audit was conducted from January to February 2017 to evaluate the utilization of the spinal clinic in relation to individual patient Keele STarT Back prognostication scores and to compare these with national guidelines. A total of 50 patients' case notes were reviewed over the four-week period. The focus was placed on how patients were made aware of the clinic, whether they had been seen by a primary care provider, and if first-line therapies had been administered. The results of this study demonstrate that some improvement is required in patient management and seek to provide recommendations for optimizing the service.

Exploring the Roles and Responsibilities of an Educational Supervisor in Medical Training Within the United Kingdom.

Medical trainees or junior doctors within the United Kingdom, regardless of their level of training or specialty, are assigned an educational supervisor (ES). The General Medical Council within the United Kingdom defines an ES as "a trainer who is selected and appropriately trained to be responsible for the overall supervision and management of a specified trainee's educational progress during a clinical placement or series of placements." This article critically evaluates the current literature to explore the roles of the ES in supporting and monitoring a trainee's progress while discussing challenges associated with the role. Through clearer delineation of the role of an ES, barriers to improving training can be identified and overcome, thus improving overall satisfaction with training.

Recurrent severe neutropenia following doxycycline use in a young healthy woman.

A 29-year-old woman was hospitalized for fever, pharyngitis, and severe neutropenia after recent use of doxycycline and other antimicrobials. Three years later, she again presented with severe neutropenia after recent doxycycline use. Diagnostic workups were unyielding. This is only the second published case of severe neutropenia associated with doxycycline use.

Adult Stem Cells for Cartilage Regeneration.

As cartilage is an avascular, aneural structure, it has very low capabilities of self-repair. Osteoarthritis prevalence is increasing, and there are no clinically approved management techniques that can cure the degradation of cartilage. This report investigates the efficacy of different sources of cells to generate articular cartilage. Autologous chondrocyte implantation has been used to some extent in clinics; however it has not generated efficient, reliable results, and there is no evidence of long-term success. The usage of stem cells is more promising, particularly mesenchymal stem cells (MSCs). Human embryonic stem cells (hESCs) have also been trialed; however, it is important to note that the process of differentiation into chondrocytes is not fully understood, and the cartilage produced can often be of poor quality. MSCs seems to be the way forward, and hESCs will perhaps need further study with the usage of MSC differentiation methodology.

Surgical Fixation of Three- and Four-Part Proximal Humeral Fractures Using the Proximal Humeral Interlocking System Plate.

Introduction The management of proximal humeral fractures ranges greatly from conservative management to surgical treatment. For those fractures requiring surgical treatment, internal fixation is the primary method. The aim of internal fixation is to achieve rigid fracture fixation until union occurs, return of shoulder range of motion, and minimise intra-and postoperative complications. The aim of this study was to evaluate the results of the Proximal Humeral Interlocking System Plate (PHILOS) used for the treatment of three-and four-part proximal humeral fractures. Materials and methods This study included 30 patients with a mean age of 54 years (range 20-80 years). Results were checked post-operatively with standard radiographs and clinical evaluation according to the Constant-Murley shoulder score. All patients were followed up for 12 months. Results Union was achieved in all patients with a mean neck/shaft angle of 130° (range 108°-150°). The mean Constant-Murley score at the final follow-up was 82.28 (range 67-96) correlating with good results. No patients developed an intraoperative or postoperative vascular injury, wound complications, or avascular necrosis of the humeral head. Conclusion Our study has shown that the surgical treatment of three- and four-part proximal humeral fractures with the use of the PHILOS plate leads to a good functional outcome. It has also demonstrated the PHILOS plate and is an effective system for fracture stabilisation provided the correct surgical technique is used with awareness of potential hardware complications.

Value of Drains in Soft-Tissue Tumour Surgery: A Specialist Regional Centre Experience.

Background The mainstay of therapy in most soft-tissue tumours (STTs) is excision. However, this often results in blood/extracellular fluid collection within large dead spaces necessitating the use of surgical drains. Whether meticulous attention to haemostasis, careful closure of dead space, and use of compression bandage obviates the need for drains was investigated. This study aimed to compare postoperative outcomes in patients undergoing surgery for STTs with and without the use of drains. Methodology A retrospective analysis of patients undergoing STT surgery over five years was undertaken using a regional STT specialist service database. Patients were stratified into the following two groups: compression bandage alone (CB) versus compression bandage with drain (CBD). The chi-square test was used to examine associations with infection, seroma, and haematoma, while the unpaired t-test was used for associations with hospital stay and time to wound healing. The unpaired t-test with Bonferroni correction was used to account for tumour dimensions across both groups. Results A total of 81 CB and 25 CBD patients were included. The mean hospital stay was significantly lower in CB compared to CBD (4.9 days, SD = 8.574 vs. 9.8 days, SD = 7.647, p = 0.0125). None of the other variables was significantly different between the two groups, including infection (21.3% vs. 24.0%, p = 0.7804), seroma (25.0% vs. 36.0%, p = 0.2865), haematoma (0.026% vs. 2.0%, p = 0.2325), and time to wound healing (55.8 days, SD = 63.59 vs. 42.3 days, SD = 58.88, p = 0.3648). Conclusions Our findings suggest that the use of drains in patients undergoing STT tumour surgery lengthens hospital stay without reducing the incidence of postoperative complications/time to wound healing. A larger, prospective trial is needed.

A Case of Embolic Spread of Fusobacterium necrophorum From Presumed Pharyngitis.

Fusobacterium necrophorum is the most common pathogen isolated in individuals diagnosed with the rare and life-threatening illness known as Lemierre's syndrome. Lemierre's syndrome commonly involves a triad of infection in the oropharyngeal region, thrombophlebitis of the internal jugular vein, and distant metastases of said infection. Our case involves an embolic spread of F. necrophorum to the lungs, which was presumed to have originated in the pharynx, in the absence of internal jugular vein thrombosis. The clinical course of the patient was further complicated by an initial diagnosis of community-acquired pneumonia, severe sepsis, and disseminated intravascular coagulation. After suitable input from the multi-disciplinary team and adequate antibiotic therapy, the patient demonstrated a positive outcome with complete recovery to her baseline.

Unilateral Testicular Tuberculosis: An Extra-Pulmonary Manifestation.

The pathogenicity of Mycobacterium tuberculosis (M. tuberculosis) causes it to most commonly manifest within the respiratory system (pulmonary tuberculosis); however, 15% of cases undergo extra-pulmonary spread to various organs. Genitourinary tuberculosis (GUTB) is a rare form of tuberculosis infection which has a propensity to affect the genitourinary tract, primarily affecting the kidneys, epididymis, seminal vesicles and prostate; however, 0.5% of cases result in infection of the testicles. This may present unilaterally or bilaterally with varying atypical presentations, thus misleading physicians in diagnosis. We present a case in a 48-year-old patient admitted to the surgical assessment unit in our hospital presenting with a unilateral painful testicular lesion and scrotal changes. He was admitted nine weeks prior for unexplainable constitutional symptoms however presented again whilst awaiting follow up in an outpatient clinic. Ultrasound guidance and fine-needle aspiration & culture (FNAC) of the lesion resulted in a positive diagnosis for M. tuberculosis. He underwent anti-tuberculous chemotherapy treatment for six months as per clinical guidance with adequate clinical response.

Disseminated intravascular coagulation following induction of labour with misoprostol: a case report.

BACKGROUND: Disseminated Intravascular coagulopathy (DIC) has been reported following use of Misoprostol which is an old drug with new indications in Obstetrics and Gynecology. Its effectiveness, low cost, stability in tropical conditions and ease of administration as well as side effects like gastrointestinal effect, uterine rupture and post partum haemorrhage (PPH) have been documented. METHOD: This is to report a case of disseminated intravascular coagulopathy (DIC) associated with use of misoprostol for induction of labour and to call for extra vigilance in its use. RESULT: This was a case of 22-year old gravida 2 para 1 at 42 weeks gestation that was induced with 100 microg of misoprostol and delivered a live female baby with good Apgar score. She subsequently developed PPH and epistaxis simultaneously, then conjunctival haemorrhage 30 minutes later. She was managed with fresh whole blood and had a satisfactory recovery. CONCLUSION: Life threatening complication could result from use of Misoprostol. More research and high index of suspicion are needed to establish the association of prostaglandins with DIC.

Comparison of emergency caesarean section to misoprostol induction for the delivery of antepartum eclamptic patients: a pilot study.

BACKGROUND: Eclampsia has now emerged as one of the commonest cause of maternal mortality in Nigeria. There is need for research on best modality for delivery of eclamptics. METHODOLOGY: The pilot study was conducted on 50 eclamptic patients at the Federal Medical Centre, Azare. The patients were randomized for delivery either by caesarean section (CS) or induction of labour. The fetomaternal outcome of the two groups was compared. RESULTS: 25 of the patients had CS and 25 had induction of labour with misoprostol. The mean decision delivery interval was 4.1 hours and 13.08 hours for the CS and misoprostol groups respectively. Misoprostol failure was recorded in 4 (16%) patients and they were subsequently delivered by CS. The duration of admission was longer in the CS group (mean of 10.1 days) compared to the misoprostol group (mean of 6.08 days). There were more maternal complications and admissions of babies into the SCBU in the CS group. Maternal mortality in the two groups was similar (2% each). CONCLUSION: Misoprostol is cheap, available and safe for delivery of antepartum eclamptics. In the event of delay at caesarean section for antepartum eclamptics patients, misoprostol induction should be started. A multicenter study is called for.

Improvement in C-reactive protein and advanced glycosylation end-products in poorly controlled diabetics is independent of glucose control.

We studied the efficacy of four different treatment regimens (sulphonylurea and metformin+/-acarbose versus glimepiride and rosiglitazone versus glimepiride and bedtime NPH insulin versus multiple actrapid and NPH insulin injections) in poorly controlled type 2 diabetes subjects on hs-CRP, VCAM-1 and AGE at 4, 8 and 12 weeks of treatment. Multiple insulin injections rapidly improved HbA(1c) by 0.6+/-0.9% (p<0.005), 1.2+/-1.3% (p<0.0005) and 1.3+/-1.4% (p<0.0005) at week 4, at week 8 and week 12, respectively. Subjects who continued their existing combination treatment of sulphonylurea, metformin+/-acarbose also showed a significant reduction in HbA(1c) (p<0.05). Although effective in reducing glycemic parameters, there was no reduction in CRP levels in either treatment group. The treatment regimen consisting of rosiglitazone and glimepiride significantly lowered hs-CRP by -2.6 (3.9) mg/L (p<0.05) at week 12 in spite of no improvement in blood glucose. AGE improved in all groups irrespective of type of treatment, glycaemic control and CRP levels. Our data indicate rapid glycaemic control alone does not necessarily result in improvement in markers of inflammation in type 2 diabetes patients.

Direct costs of pulmonary tuberculosis among patients receiving treatment in Bauchi State, Nigeria.

BACKGROUND: To access tuberculosis (TB) services, patients have to bear the costs of out-of-pocket expenditures or direct costs for transport, drugs and other services that are not provided free-of-charge. These costs could represent a barrier to care, especially in a country such as Nigeria, where per capita gross national income is only US$1160 and 46% of the urban population live below the poverty line. OBJECTIVE: To describe the direct costs of TB diagnosis and treatment in Bauchi State, Nigeria, from the patient's perspective. METHODS: A cross-sectional study. A sample size of 255 patients was randomly selected from 27 of 67 facilities in Bauchi State, Nigeria. RESULTS: The median out-of-pocket cost for hospitalised patients was estimated at US$166.11, while ambulatory patients paid an estimated median cost of US$94.16, equivalent to about 9-38% of their average annual income. Female patients spent a higher proportion of their income on diagnosis and treatment than males (P < 0.0001). The median out-of-pocket costs borne by patients before, during and after diagnosis were estimated at respectively US$35.23, US$27.12 and US$23.43 for ambulatory patients, and additional average out-of-pocket spending of US$66.44 for patients hospitalised during their illness. Pre-diagnosis, diagnosis and post-diagnosis out-of-pocket spending did not vary significantly by human immunodeficiency virus status (P > 0.05) and sex (P > 0.05). CONCLUSION: The costs of anti-tuberculosis treatment found in this study are expensive and potentially catastrophic for many patients and their families.

Embryonal rhabdomyosarcoma of the cervix.

Embryonal rhabdomyosarcoma (sarcoma botyroides) of the cervix, which is rare, is described in a 16-year-old. The combined use of chemotherapy, radiotherapy and surgery has markedly improved survival in those with this condition. However, our patient did not benefit from this treatment modality due to late presentation and loss to follow-up.
