Optic nerve sheath fenestration via a supero-medial eyelid skin crease approach for the treatment of idiopathic intracranial hypertension in a UK population.

BACKGROUND/AIMS: Optic nerve sheath fenestration (ONSF) is a surgical intervention in the management of idiopathic intracranial hypertension (IIH) infrequently performed in the United Kingdom. Numerous surgical approaches have been described, including medial transconjunctival, lateral and endoscopic. We describe our outcomes and complications from ONSF via a supero-medial eyelid skin crease incision in patients with IIH. METHODS: We performed a retrospective review of consecutive patients undergoing ONSF for IIH between January 2011 and December 2017 by a single surgeon. RESULTS: Thirty patients were included in the analysis with a median follow-up of 14.5 months. Bilateral ONSFs were undertaken in 27 (90%). The data from one eye per patient were analysed. The mean kinetic perimetry score in mean radial degrees of the I4e isopter improved from 27.3° to 35.7°, p = 0.04. After removing cases with optic atrophy, the median modified Frisén grade of papilloedema improved from 2.5 to 1.0, p = 0.007. A total of 5/30 (17%) patients had complications: two (7%) had recurrence/late failure (one managed medically and one with cerebrospinal fluid [CSF] diversion surgery), one had transient cotton wool spots post-operatively, one had transient retinal haemorrhages and one patient had a transiently oval pupil. No patients had repeat ONSF, but CSF diversion surgery was subsequently carried out in 4/30 (13%) patients. CONCLUSIONS: ONSF via a supero-medial eyelid skin crease approach is effective at improving visual function in patients with IIH. The complication rates are low when compared with CSF diversion surgery and other surgical approaches for ONSF.

Impact of weight management nutrition interventions on dietary outcomes in children and adolescents with overweight or obesity: a systematic review with meta-analysis.

BACKGROUND: The impact of obesity interventions on dietary intake in children and adolescents with overweight or obesity is unclear. This systematic review aimed to investigate the impact of the dietary component of weight management interventions on the change in diet in children and adolescents with overweight or obesity. METHODS: Eligible randomised controlled trials (RCTs) published between 1975 and 2020 were identified by a systematic search following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Meta-analyses of eligible study outcomes were performed using statistical software. A multilevel random effects model was used with three significant random effects fitted using restricted maximum likelihood estimation. RESULTS: This review identified 109 RCTs, including 95 that reported at least one statistically significant dietary outcome change and 14 reporting no significant dietary change. Results from the meta-analyses (n = 29 studies) indicated that, compared to control groups, intervention groups achieved significantly greater reductions in mean total energy intake at ≤6 months (-194 kcal day-1 , 95% confidence interval = -275.80 to -112.90 kcal day-1 , P < 0.001) and up to 12 months (-112 kcal day-1 95% confidence interval = -218.92 to -5.83 kcal day-1 ) P = 0.038), increases in fruit and/or vegetable intakes over 2-12 months (n = 34, range +0.6 to +1.5 servings day-1 ) and reductions in consumption of sugar-sweetened beverages (n = 28, range -0.25 to -1.5 servings day-1 ) at 4-24 months follow-up. CONCLUSIONS: Obesity interventions with a dietary component have a modest but sustained impact on reducing total energy intake and improving intakes of specific food groups in children and adolescents with overweight or obesity. High quality RCTs that are powered to detect change in diet as a primary outcome are warranted.

Offering HCV treatment to prisoners is an important opportunity: key principles based on policy and practice assessment in Europe.

BACKGROUND: Prisoners have a high prevalence of hepatitis C virus (HCV) infection but may find it difficult to access healthcare services. This may be related to risk behaviour including history of injecting drugs and marginalisation related to problem drug use/ opioid use disorder (OUD). Direct-acting antiviral products with superior efficacy and safety compared to interferon-based regimens offer HCV cure. Many citizens in Europe have been treated, although few received therapy in prisons. METHODS: Analysis of prisoner HCV treatment need and policy determinants of clinical practice was completed for 5 EU countries. Evidence was collected from national statistical sources and peer-reviewed publications to describe prison populations and HCV prevalence, to map national prison/ HCV health policy or guidance. A consensus of important principles for prisoner HCV care was developed. RESULTS: Data from published sources describing prisoner HCV prevalence is limited. Prisoner population requiring HCV treatment is not known; estimated numbers based on analysis of evidence: England and Wales, 9000, France, 8000, Spain, 6000, Italy, 6000, Germany, 6000. Treatment access: national law defines right to equivalent care in all countries implying access to HCV therapy in prison similar to community; useful prisoner HCV guidance facilitating treatment decisions present in: 4 of 5 national/ regional HCV policy documents, 4 of 5 national prison healthcare policies. Four of five had practical prison HCV clinical guidelines. Despite existence of policy, implementation of guidance, and so HCV treatment, is suboptimal in many locations. CONCLUSIONS: Prison is an important location to detect, address and treat HCV infection in people who may be underserved for healthcare and find it difficult to navigate community treatment pathways. This is often related to problems with OUD and resulting social inequity. HCV management in prisons must be improved. Policy and clinical practice guidance must be set to promote treatment, and practical steps to make treatment easy should be followed including education to promote engagement, set-up of optimal screening and work up processes with modern tools to reduce time needed/ achieve efficiency; programs to make it easier to get specialists' input include remote working and nurse-led services.

Spontaneous spinal epidural haematoma mimicking meningitis in a 2-year-old child--a case report and literature review.

INTRODUCTION: We report the case of a 2-year-old boy with suspected meningitis who presented with acute onset neck pain and stiffness associated with right-sided weakness and ataxia. MANAGEMENT: Despite intravenous antibiotics and antiviral treatment, his condition deteriorated. Magnetic resonance imaging demonstrated spontaneous cervical epidural haematoma (C4-C7) extending down to thoracic (T7) level with associated compression of the spinal cord. He was treated successfully by neurosurgical decompression and made a complete recovery. DISCUSSION: Spinal epidural haematoma is a neurosurgical emergency characterised by extravasation of blood in the spinal epidural space. The clinical presentation particularly in young children can masquerade other conditions such as meningitis. In this article, we discuss our case and review the literature on spontaneous spinal epidural hematoma with an aim to improve awareness of this condition which if not recognised and treated early can lead to significant lifelong morbidity.

Mental health and intellectual disability: culture and diversity.

BACKGROUND: Compared with that in mental illness, cultural variation in popular conceptualisations of intellectual disability has been rarely addressed. METHODS: A survey of the relevant literature was conducted. RESULTS AND CONCLUSION: Preliminous conclusions are that local conceptualisation does not lead to invariant social response, but that intellectual disability is generally distinguished from mental illness.

A postmarketing surveillance study of the safety and efficacy of ReFacto (St Louis-derived active substance) in patients with haemophilia A.

This clinical trial evaluated the safety and efficacy of ReFacto (St Louis-derived active substance) in patients with severe or moderately severe haemophilia A over a period of 6 months or 50 exposure days (EDs), whichever occurred first. Sixty patients, 58 previously treated and two previously untreated, were enrolled into this study. This was an open-label, multicentre, postmarketing surveillance study in which patients received prophylaxis or on-demand treatment as determined by their doctor. Surgical prophylaxis was evaluated in seven patients requiring elective surgery. Thirty-two patients aged <1 to 66 years (median 19.5) received prophylaxis and 28 patients, aged 1-71 years (median 33.5), received on-demand treatment. The majority of patients had severe haemophilia A (FVIII:C < 2%): 84.4% in the prophylaxis group and 85.7% in the on-demand group. Prophylaxis with ReFacto was associated with a median of 6.7 bleeds per year (range: 0-37). The investigator's assessment of final outcome for prophylactic treatment was excellent or effective for 93.1% of patients. ReFacto resolved 92.8% of bleeds with one or two infusions. The investigator's assessment was excellent or good for 98.2% of bleeds treated with ReFacto. Haemostasis was achieved for all seven surgical cases and ReFacto gave an excellent or good response for each. The nature and incidence of adverse events was as expected and no new safety concerns emerged. One previously treated patient (PTP) developed a high-titre inhibitor (maximum 75 BU) and one minimally treated patient (MTP) developed a low-titre inhibitor while on the study but eventually achieved high titres (maximum 30 BU) after immune tolerance therapy was initiated with a plasma-derived FVIII product. One previously untreated patient (PUP) developed a transient low-titre inhibitor (0.4 BU). Other serious adverse events (SAEs) were unrelated to study treatment. There were no allergic events. The results of this study are consistent with the previously published ReFacto pivotal studies.

Measured and predicted total body water in children with myelomeningocele.

OBJECTIVE: Children with myelomeningocele (MMC) have an altered body composition and an atypical distribution of total body water (TBW). The aim of the present study was to determine the accuracy of current predictive equations, based on bioelectrical impedance analysis (BIA), in determining TBW when compared with measured TBW using deuterium dilution. METHODS: Fourteen children with MMC were measured for whole body BIA and TBW (using deuterium dilution and the Plateau method). Total body water was predicted using equations based on the resistance and characteristic frequency from BIA measurements and heights of subjects. RESULTS: The mean measured TBW was 15.46 +/- 8.28 L and the mean predictions for TBW using equations based on the resistance and characteristic frequency from BIA measurements and heights of subjects were 18.29 +/- 8.41 L, 17.72 +/- 11.42 L and 12.51 +/- 7.59 L, respectively. The best correlation was found using characteristic frequency. The limits of agreement between measured and predicted TBW values using Bland-Altman analysis were large. CONCLUSIONS: The present study suggests that the prediction of TBW in children with MMC can be made accurately using the equation of Cornish et al. based on BIA measurements of characteristic frequency.

Comparison of the Cosmed K4 b(2) and the Deltatrac II metabolic cart in measuring resting energy expenditure in adults.

BACKGROUND AND AIMS: The objective of the study was to compare data obtained from the Cosmed K4 b(2) and the Deltatrac II metabolic cart for the purpose of determining the validity of the Cosmed K4 b(2) in measuring resting energy expenditure. METHODS: Nine adult subjects (four male, five female) were measured. Resting energy expenditure was measured in consecutive sessions using the Cosmed K4 b(2), the Deltatrac II metabolic cart separately and the Cosmed K4 b(2) and Deltatrac II metabolic cart simultaneously, performed in random order. Resting energy expenditure (REE) data from both devices were then compared with values obtained from predictive equations. RESULTS: Bland and Altman analysis revealed a mean bias for the four variables, REE, respiratory quotient (RQ), V CO(2), V O(2) between data obtained from Cosmed K4 b(2) and Deltatrac II metabolic cart of 268+/-702 kcal/day, -0.0+/-0.2, 26.4+/-118.2 and 51.6+/-126.5 ml/min, respectively. Corresponding limits of agreement for the same four variables were all large. Also, Bland and Altman analysis revealed a larger mean bias between predicted REE and measured REE using Cosmed K4 b(2) data (-194+/-603 kcal/day) than using Deltatrac metabolic cart data (73+/-197 kcal/day). CONCLUSIONS: Variability between the two devices was very high and a degree of measurement error was detected. Data from the Cosmed K4 b(2) provided variable results on comparison with predicted values, thus, would seem an invalid device for measuring adults.

Psychotherapy in cultural contexts.

This article examines gender politics, culture, and race, as well as therapy and social transition, as they relate to psychotherapy in cultural contexts. Examples of gender politics in Kenya and Somalia are discussed. Rites of passage as they relate to psychiatric illness also are discussed. "Therapeutic cure" as defined in various cultures also is reviewed.

Against over-interpretation: the understanding of pain amongst Turkish and Kurdish speakers in London.

The understanding of experienced pain has recently moved from the biological to the metaphorical. Detailed interviews with twelve Turkish and Kurdish patients in London who had been unsuccessfully investigated medically for chronic pain showed that their understanding reflected local, typically humoural, conceptions of self and body. However there was little to suggest interpretation of the illness as a more specific and grounded idiom for social or political experience. It is suggested that the current vogue for 'interpretation' in medical anthropology and social psychiatry may occasionally be, as Umberto Eco puts it, 'over-interpretation'.

Social institutions and psychological explanations: Druze reincarnation as a therapeutic resource.

For Emile Durkheim, to explain our social institutions through individual psychology was generally regarded as illegitimate. It has, however, often been assumed by psychologists and psychiatrists, particularly in the case of religious doctrine and institutions. However, the people actually concerned, our religious informants, might sometimes themselves volunteer interpretations which are psychologically functional for the origin and maintenance of certain cultural facts. This is particularly so when they are faced with a 'modern' worldview. The instance of the Druze belief in bodily reincarnation after death is considered in the context of the recent civil war in the Lebanon.

Resting energy expenditure of children attending a rehabilitation programme following head injury.

STATEMENT OF PURPOSE: Increased resting energy expenditure following head injury is well documented, but whether this increase extends into rehabilitation and whether this is affected by changes in body composition have not been studied. The aim of this study was to determine whether children attending a rehabilitation program following head injury had altered energy expenditure and body composition. METHODS: Measurements of resting energy expenditure by indirect calorimetry were performed in 21 head injured children (mean age 10.2 +/- 3.8 years). Measurement of body composition was performed using total body potassium. RESULTS: Measured resting energy expenditure values were widely distributed, ranging from 52.3-156.4% of predicted values, yet the mean percentage predicted using Schofield weight, Schofield weight and height and World Health Organization predictive equations were 97.5%, 97.4% and 98.6%, respectively. Mean percentage of expected total body potassium for weight, height and age for head injured children were 85.1 +/- 15.5%, 89.1 +/- 14.1% and 86.9 +/- 15.9%, thus all showed significant depletion. CONCLUSIONS: During rehabilitation, using predictive equations to estimate resting energy expenditure in this group revealed a small bias on average but very large bias at the individual level. Head injured children had altered resting energy expenditure and body composition.

Perceptions about mental illness among pre-clinical medical students in Trinidad & Tobago.

Perceptions about mental illness among medical practitioners are likely to determine their capacity to recognise, treat appropriately and refer patients who have mental health problems. It is therefore important that training of medical students in psychiatry is undertaken with knowledge of their attitudes to mental health disorders. We determined the perceptions of 108 pre-clinical medical students (69 males, 39 females; mean age 22 years) toward mental illness in Trinidad & Tobago by analysing their responses to a questionnaire based on a case vignette of a young man with a paranoid psychotic illness. 88% felt that medical treatment in hospital was the best means of treating the illness and 86% suggested that discharge should be conditional on regular visits to a doctor. 89% however opposed the patient's marrying into their families and 85% to his teaching their children. This was associated significantly with having a personal relationship with someone having a mental illness (p < 0.03). Surprisingly, 25% believed that mental illness could be caused by supernatural forces, particularly females who were almost twice as likely as males to express this belief.

Reduced body cell mass following severe head injury in children: implications for rehabilitation.

STATEMENT OF PURPOSE: Increased proteolysis, muscle catabolism and altered body composition have been well documented after severe head injury, but the extent of these effects in children, and whether they extend into rehabilitation, have not been studied. This study determined nutritional status and body composition, with particular reference to the body cell mass (BCM), of head injured children at entry into a rehabilitation programme, and compared body composition analysis with anthropometric nutritional assessment. METHODS: Nineteen head injured children (nine males, 10 females, mean age 9.1 +/- 4.3 years range 1.2-15.1 years) were measured for height, weight and total body potassium (TBK, a measure of body cell mass) on referral to rehabilitation after the acute phase (mean 38.1 days post-injury). Data was compared with expected normative data derived from healthy age and gender matched children. Nutritional status was determined by two separate criteria based on either anthropometric or body composition methods. RESULTS: The mean percentage of expected TBK for height was 84.4 +/- 15%, significantly below the clinically acceptable level for body cell mass (90% of expected). Using the anthropometric definition, only 1/19 was undernourished, whereas 12/19 had poor nutritional status using body composition (chi 2 = 7.58, p = 0.006). CONCLUSIONS: The data revealed a significant depletion in the metabolically active BCM in the presence of normal anthropometry, suggestive of significant muscle wasting. These findings have important pathophysiological and clinical implications in the rehabilitation of children following major head trauma.

Patient satisfaction: ethnic origin or explanatory model?

Despite concern over their psychiatric treatment, little is known about black and ethnic minority patient satisfaction with psychiatric services and whether perceived 'ethnicity' or discrepant understanding of illness experience is most relevant. Twenty-one white British and 63 ethnic minority patients were interviewed for their opinions on psychiatric in-patient care, their treatment preferences and their explanatory models of their illness. The most significant association with satisfaction was not ethnic origin but the patient's explanatory model of their illness which showed little association with ethnicity whether patients were voluntary or involuntary. Satisfaction is most likely when there is concordance between the patient's and psychiatrist's explanatory model.

The effects of two doses of replacement growth hormone on the biochemical, body composition and psychological profiles of growth hormone-deficient adults.

This study examined the effects of growth hormone (GH) replacement on the insulin-like growth factor-I (IGF-I), body composition and psychological profiles of GH-deficient adults. We assessed whether two doses of GH produced different effects on these variables and whether patients who, at the end of the study chose to remain on long-term GH replacement responded differently to those who chose to abandon therapy. Forty-two adults (aged 42.9 +/- 1.9 years (mean +/- S.E.M.)) with documented GH deficiency entered two studies (24 in study 1, 18 in study 2). Biochemical, body composition and psychological profiles were assessed at baseline, and after 6 months and 1 year. Psychological assessments were performed using well-established, independent, validated 'Quality of Life' questionnaires (Nottingham Health Profile (NHP) and the Psychological General Well-Being Schedule (PGWB)). The study protocols differed only in the doses of growth hormone (0.024 mg/kg per day and 0.012 mg/kg per day respectively). Comparison between studies and between patients eventually continuing and abandoning GH therapy was performed. GH replacement was associated with significant changes in IGF-I levels (P < 0.001), body composition (P < 0.01) and self-perceived well-being (NHP, P < 0.01; PGWB, P < 0.01). The higher dose of GH produced a greater IGF-I response than the lower dosage (44.6 +/- 7.3 vs 26.2 +/- 3.6 nmol/l, P < 0.05), but no better psychological response (NHP, P = 0.22; PGWB, P = 0.23). Those deciding to continue replacement therapy did not respond differently to those choosing to abandon therapy with respect to IGF-I (P = 0.72), body composition (P = 0.38) and psychological assessment (NHP, P = 0.29; PGWB, P = 0.24). GH replacement in GH-deficient adults was associated with significant improvements in self-perceived well-being as well as changes in body composition and other variables. This improvement was similar at two different doses of replacement GH. Those patients electing to continue on long-term replacement did not achieve a demonstrably different psychological, body composition or biochemical benefit to those patients deciding to discontinue replacement.
