Unusual case of camptocormia triggered by lumbar-disc herniation

A 21-year-old male patient with low back pain and marked forward bending was presented. The exaggerated lumbar flexion was preventing him to stand in erect posture but disappeared while lying. The symptoms had begun after he had lifted a heavy object. Straight-leg-raising test could not be performed properly because of the exaggerated pain. The light-touch sense was decreased on L5 and S1 dermatomes. There was no loss of muscle strength. The deep-tendon reflexes were normal. Plain graph showed mild narrowing in the L4–5 and L5–S1 intervertebral spaces. Lumbar magnetic resonance imaging revealed disc protrusions in L4–5 and L5–S1 levels. During his stay in the department, the patient was given tizanidine and tramadol, and physical therapy was performed. A paravertebral intramuscular injection with lidocaine was applied. Moreover, the patient was referred to psychiatrist for evaluation regarding his medical history of conversive seizures and possible efforts for secondary gain. No response was obtained from all the treatments. The final diagnosis was camptocormia triggered by lumbar-disc herniation. He was applied supportive psychotherapy, psychoeducation regarding secondary gain, strong suggestions to improve posture, positive reinforcement, and behavioral therapy. His postural abnormality resolved and disappeared completely with mild pain.

Pragmatic Trials in Long-Term Care: Implementation and Dissemination Challenges and Opportunities

Randomized controlled trials are considered the most rigorous research design in efficacy and effectiveness research; however, such trials present numerous challenges that limit their applicability in real-world settings. As a consequence, pragmatic trials are increasingly viewed as a research design that overcomes some of these barriers with the potential to produce findings that are more reproducible. Although pragmatic methodology in long-term care is receiving increasing attention as an approach to improve successful dissemination and implementation, pragmatic trials present complexities of their own. To address these complexities and related issues, experts with experience conducting pragmatic trials, developing nursing home policy, participating in advocacy efforts, and providing clinical care in long-term care settings participated in a virtual consensus conference funded by the National Institute on Aging in Spring 2021. Participants identified 4 cross-cutting principles key to dissemination and implementation of pragmatic trial interventions: (1) stakeholder engagement, (2) diversity and inclusion, (3) organizational strain and readiness, and (4) learn from adaptations. Participants emphasized that implementation processes must be grounded in the perspectives of the people who will ultimately be responsible for implementing the intervention once it is proven to be effective. In addition, messaging must speak to long-term care staff and all others who have a stake in its outcomes. Although our understanding of dissemination and implementation strategies remains underdeveloped, this article is designed to guide long-term care researchers and community providers who are increasingly aware of the need for pragmatism in disseminating and implementing evidence-based care interventions.     

Knowledge and attitudes of family doctors,dermatologists, and endocrinologists on sun exposure and vitamin D

Objectives: Vitamin D is an important component of bone metabolism. Skin cells synthesize vitamin D when exposed to the sun. However, prolonged sun exposure damages the skin and increases the risk for skin cancer. The objective is to evaluate and compare the attitudes and recommendations of family doctors, dermatologists, and endocrinologists on exposure to the sun and vitamin D.

Methods: In a cross-sectional study, a questionnaire was completed by personal interview in a study population of 78 family doctors, 21 dermatologists, and 22 endocrinologists.

Results: On a scale of 1–10, the mean score for recommendations to reduce sun exposure was 4.7 for dermatologists, 4.2 for endocrinologists, and 6.4 for family doctors (p < 0.001). Family doctors recommended a mean daily exposure to the sun of 67.4 min compared to 41.4 by dermatologists, and 47.1 by endocrinologists (p = 0.007). Dermatologists and endocrinologists were more likely to recommend protective measures such as hats and long sleeves during sun exposure than family doctors (p < 0.0001). There were no statistically significant differences between male and female doctors for the entire study population.

Conclusions: There is little consensus among these medical practitioners, whether specialists or primary care doctors, concerning sun exposure. Further studies should evaluate the optimal duration and intensity of sun exposure and doctors’ recommendations should be based on the findings.     

Rod-Cone Dystrophy with Initially Preserved Visual Acuity Despite Early Macular Involvement Suggests Recessive CERKL Mutations

Purpose: To highlight that recessive CERKL mutations cause an early-onset rod-cone dystrophy with initially preserved visual acuity despite early macular involvement, an unusual and distinct initial phenotypic presentation.

Methods: A retrospective case series.

Results: Two young Saudi Arabian adults complained of worsening night blindness over the preceding few years, one of whom had been symptomatic since early childhood. Both had retinal pigment epithelium (RPE) mottling/granularity, vascular attenuation, few bone spicules, and frank macular RPE atrophic changes despite relatively preserved visual acuity. Electroretinography was non-recordable, and ocular coherence tomography confirmed retinal thinning, particularly of the outer nuclear layer in the fovea. Each patient harbored a different homozygous CERKL mutation (p.L245P, p.C333*). The few prior reports that detail the presenting phenotype of CERKL mutations describe children or young adults with the similar unusual presenting constellation of findings: rod-cone dystrophy and frank macular atrophy but relatively preserved visual acuity. With time, central vision is affected.

Conclusions: The initial presenting features of CERKL-related retinopathy are distinct and unusual. Recognition of this initial presenting phenotype can facilitate earlier molecular diagnosis and genetic counseling.     

Analysis of misoprostol and chlorhexidine policy gains in Pakistan: the advocacy experience of Mercy Corps Pakistan

While Pakistan has made progress toward achieving Millennium Development Goal 5 for maternal health, it is unlikely to achieve the target; further, it is also not on track for Millennium Development Goal 4 regarding child health. Two low-cost, temperature stable and life-saving drugs, misoprostol and chlorhexidine, can respectively avert maternal and newborn deaths, and are particularly pertinent for poor and marginalized areas which bear the brunt of maternal and newborn deaths in Pakistan. In response, Mercy Corps led focused advocacy efforts to promote changes in policies, protocols, and regulatory environments for misoprostol (2012–2014) and for chlorhexidine (2014). These short-duration advocacy projects facilitated significant policy gains, such as inclusion of misoprostol and chlorhexidine into province-specific essential drug lists, development and endorsement of clinical protocols for the two drugs by provincial health departments, inclusion of misoprostol into pre-service training curriculum for several health cadres, and application for registration of chlorhexidine (at the concentration required for newborn care) by two pharmaceutical companies. These results were achieved by a consultative and evidence-based process which generated feedback from community members, program implementers, and policymakers, and ultimately put the government in the driver’s seat to facilitate change. Community Action Dialogue forums were linked with provincial-level Technical Working Groups and Provincial Steering Committees, who passed on endorsed recommendations to the Health Secretary. The key factors which facilitated change were the identification of champions within the provincial health departments, prioritization of relationship building and follow-up, focus on concrete advocacy aims rather than broad objectives, and the use of multi-stakeholder forums to secure an enabling environment for the policy changes to take root. While these advocacy initiatives resulted in significant policy changes in Pakistan’s devolved health system, to ensure these policy changes have an impact on health outcomes, Pakistan should focus on the scale-up of appropriate use of chlorhexidine and misoprostol. Further, future policy initiatives in Pakistan should make use of similar multi-stakeholder policy forums, while ensuring a third party to facilitate the process so that civil society and community voices are not lost in the policy development discussion.     

Novel Z Scores to Correct Biases Due to Ventricular Volume Indexing to Body Surface Area in Adolescents and Young Adults

BackgroundReference values for cardiac magnetic resonance imaging (cMRI) in children and young adults are scarce. This leads to risk stratification of patients with congenital heart diseases being based on volumes indexed to body surface area (BSA). We aimed to produce cMRI Z score equations for ventricular volumes in children and young adults and to test whether indexing to BSA resulted in an incorrect assessment of ventricular dilation according to sex, body composition, and growth.MethodsWe retrospectively included 372 subjects aged < 26 years with either normal hearts or conditions with no impact on ventricular volumes (reference group), and 205 subjects with repaired tetralogy of Fallot (TOF) aged < 26 years. We generated Z score equations by means of multivariable regression modelling. Right ventricular dilation was assessed with the use of Z scores and compared with indexing to BSA in TOF subjects.ResultsVentricular volume Z scores were independent from age, sex, and anthropometric measurements, although volumes indexed to BSA showed significant residual association with sex and body size. In TOF subjects, indexing overestimated dilation in growing children and underestimated dilation in female compared with male subjects, and in overweight compared with lean subjects.ConclusionsIndexed ventricular volumes measured with cMRI did not completely adjust for body size and resulted in a differential error in the assessment of ventricular dilation according to sex and body size. Our proposed Z score equations solved this problem. Future studies should evaluate if ventricular volumes expressed as Z scores have a better prognostic value than volumes indexed to BSA.

The association of childhood asthma with mental health and developmental comorbidities in low-income families

Objective: The objective of the study was to determine the relationship of childhood asthma with mental health and developmental indicators in low-income families. Methods: Parents/guardians of approximately 400 children, aged 2–14 years, were recruited from a charity hospital serving low income neighborhoods in the outskirts of Karachi, Pakistan. Mothers of children were interviewed in their local language by a trained nurse. Eight self-reported comorbidities were grouped into two constructs based on factor analysis and conveniently labeled as mental health (anxiety, attention and behavioral problems) and developmental problems (learning, developmental delay, hearing impairment, sleep and speech problems). Data were analyzed using multiple logistic regression, adjusted for age, sex, presence of older siblings, number of people in the household, child birth weight, presence of mold, and family history of asthma or hay fever. Results: Children with asthma had 18 times greater odds of mental health problems (adjusted OR?=?18.0, 95% CI: 9.2, 35.1) as compared to children without asthma. The odds of developmental problems were more than 14 times greater for children with asthma (adjusted OR?=?14.3, 95% CI: 7.8, 26.1) as compared to children without asthma. Conclusions: This study found mental and developmental adverse consequences of childhood asthma in low-income families. Identifying and treating asthma at an early age could reduce the burden of comorbidities in this population.     

Performance of the OptiMAL test for malaria diagnosis among suspected malaria patients at the rural health centers

The OptiMAL test detects both Plasmodium falciparum and P. vivax malaria infections. In this study, we evaluated the performance of the OptiMAL test at the Basic Health Units (BHUs) and the District Health Quarter (DHQ) Center in rural villages of Punjab, Pakistan that provide minimal health services. Two sets of blood specimens obtained from 930 suspected malaria patients attending these BHUs were tested at BHUs and the DHQ Center by microscopy and the OptiMAL test. At the BHUs, 231 (25%) of the patients were positive by microscopy and 278 (30%) patients tested positive by the OptiMAL test. At the DHQ Center, microscopic analysis of a second set of specimens from the same patients confirmed the malaria infection in 386 (42%) patients and the OptiMAL test result was positive in 300 (32%) patients. To determine the performance of OptiMAL test at the BHUs and the DHQ Center, all data were compared with microscopy results obtained at the DHQ Center. The OptiMAL test results for P. falciparum at the BHUs were comparable to those of the OptiMAL test at the DHQ Center. However, the sensitivity, positive predictive value (PPV), and negative predictive value (NPV) of the OptiMAL test were considerably lower for P. vivax infections than for P. falciparum infections, irrespective of whether the test was performed at the BHUs or at the DHQ Center (P. falciparum: sensitivity = 78-85%, PPV = 89-97%, NPV = 96-98%; P. vivax: sensitivity = 61-76%, PPV = 88-95%, NPV = 90-93%). The OptiMAL test also detected a number of false-positive and false-negative results at both the BHUs and the DHQ Center. The false-positive results ranged from 1% to 2%; however, the number of false-negative results was much higher (BHUs: P. falciparum = 22%, P. vivax = 39%; DHQ Center: P. falciparum = 15%, P. vivax = 24%). In conclusion, these results, when combined with other advantages of the OptiMAL test, suggest that this test can be used by relatively inexperienced persons to diagnose malaria infection in rural areas where facilities for microscopy are not available.
