Long-Term Disability After Traumatic Spinal Injuries: A Military Retrospective Study.

BACKGROUND: Traumatic spinal injuries (TSI) pose a significant life-long burden, impacting both military and civilian populations. Assessing long-term outcomes is crucial for comprehending the enduring consequences of the initial insult and informing effective prevention and management strategies. Most existing studies have narrowly focused on subsets of traumatic cord injuries, leaving a gap in understanding the broader impact of severe spinal trauma. This study aims to examine severe TSIs in military personnel, who may face unique risk factors and injury patterns, and its association with long-term disability. METHODS: A retrospective cohort study was conducted on all military personnel who suffered traumatic injuries (Injury Severity Score ≥ 9) from 1997 to 2020. Severe spinal injuries were defined using the spinal Abbreviated Injury Scale ≥ 3 (n = 95), and compared to all other injuries as a reference group (n = 1,394). Data were extracted and cross-referenced from three distinct nationwide registries-pre-hospital, admission, and rehabilitation. Logistic regression analysis was used to evaluate the impact of spinal injuries on long-term disabilities (defined as the highest possible disability tier). The study received approval from the institutional review board of the Israel Defense Forces Medical Corps. RESULTS: Motor vehicle accidents and falls were the primary causes of spinal injuries (50.5% and 15.8%, respectively). The median age at injury was 20 years (interquartile range 19-22). Personnel with spinal trauma had a significantly higher prevalence of Injury Severity Score ≥ 25 (46.3% vs. 19.9%, P < .001), longer median hospital stays (11 vs. 8 days, P = .036), and increased intensive care unit admissions (55% vs. 40%, P = .05). The median follow-up duration was 10.9 years (interquartile range 6.7-14.3). Spinal injuries were associated with a more than 10-fold increase in the adjusted odds ratio for severe permanent disability (11.92, 95% CI, 5.95-23.72). CONCLUSION: Upon long-term follow-up, military personnel with severe TSI exhibit a significantly higher prevalence of debilitating disability compared to those with significant non-spinal traumatic injuries. These findings highlight the critical need for targeted prevention strategies and improved management of spinal injuries to reduce long-term disability. Strengths of this study include its extensive follow-up period and the use of multiple nationwide registries. However, the study may be limited by potential discrepancies in identity matching across databases and the reliance on disability claims, which may underrepresent the true prevalence of long-term disability. Future research should explore the efficacy of early interventions and rehabilitation strategies in mitigating long-term disability following spinal injuries. This study underscores the importance of developing evidence-based policies to enhance care for individuals with TSIs.

Group A Streptococcus Carriage in Adults in Southern Israel: A Prospective Study.

BACKGROUND: The prevalence of Group A streptococcus (GAS) carriage among adults is studied less than in children. The variability of reported carriage rates is considerably large and differs among diverse geographic areas and populations. OBJECTIVES: To evaluate the prevalence of GAS carriage among adults in Israel. METHODS: In this prospective study, conducted in a large healthcare maintenance organization in Israel, we obtained pharyngeal cultures from adults attending the clinic without upper respiratory tract complaints or fever. Patient data included sex, age, number of children, and religious sectors. RESULTS: From May to December 2022, eight family physicians collected a total of 172 throat swabs (86% response rate). The median age was 37 years (range 18-65); 72.7% were females, 22.7% were ultra-Orthodox Jewish, and 69.2% had children. The prevalence of GAS carriage was 6.98%, 95% confidence interval (95%CI) 3.7%-11.9%. GAS carriers were younger (31.7 vs. 39.3 years, P = 0.046), and the majority were ultra-Orthodox Jews (58.3% vs. 20%, P = 0.006). All GAS carriers were from lower socioeconomic status. When assessing risk factors for GAS carriage using multivariate analysis, only being an ultra-Orthodox Jew was positively related to GAS carriage (adjusted odds ratio 5.6, 95%CI 1.67-18.8). CONCLUSIONS: Being an ultra-Orthodox Jew was the single variable associated with a GAS carriage, which may be related to having many children at home and living in overcrowded areas. Primary care physicians in Israel should recognize this situation when examining patients with sore throats, mainly ultra-Orthodox Jews.

Use of prescription opioids in Israel and socio-economic correlations between 2010 and 2020.

BACKGROUND: The use of opioids has increased dramatically over the past several years in Israel. The aim of this study was to explore the trends of opioid consumption in Israel over a decade (2010-2020) stratified by socioeconomic status (SES), residence in the periphery, and ethnic background. METHODS: This cross-sectional study included all adult Maccabi Healthcare Services (MHS) patients who filled at least one prescription for opioids during the past decade. In order to standardize dosages and compare different opioid medications, we used the Morphine Milligram Equivalent (MME) conversion factor. We performed The Mann-Kendall test with autocorrelation correction to assess each trend. We then checked the differences between the trends with the Mann-Whitney test (for periphery) and the Kruskal Wallis (for SES and ethnic background). RESULTS: Between the years 2010-2020, 261,270 MHS members met the study's inclusion criteria. The proportions of opioids consumption were 23.9/1000 patients in 2010 and 27.6/1000 patients in 2020, representing a 15% increase. The average daily consumption of opioids was 4.6 and 10.5 MME in 2010 and 2020, respectively, an increase of 227%. The daily MME during 2020 was higher for residents of the periphery compared to non-periphery residents (daily MME of 14.0 compared to 10.1, respectively). Average daily MME increased gradually during the study period for all levels of SES; the values were highest for the low SES group and the lowest for the high SES group (daily MME in 2020 for the lowest, middle, and high SES groups were 15.2 vs. 11.8 vs. 6.7 respectively). CONCLUSIONS: This study highlights that the primary concern in the increase of opioid use is the increasing dosages. The increase in the number of patients using opioids is also significant but to a minor extent. These phenomena disproportionately impact vulnerable populations. Education programs should be offered to physicians regarding the possible harms of long-term use of opioids. These programs should emphasize the risk factors associated with the development of opioid use disorder (OUD) and the caution needed when increasing dosages or switching to higher-potency drugs. Pain clinics and centers for rehabilitation for patients with chronic pain or OUD should be available, not only in central areas but also in the periphery of the country. These clinics and centers should use a holistic approach and a multidisciplinary team that includes specialists in pain and addiction. They should be financially accessible for patients from low SES group and provide solutions in multiple languages.

Attitudes and knowledge about weight management among primary care physicians in Israel: a cross-sectional study.

BACKGROUND: The prevalence of obesity has been increasing worldwide and is associated with increased risk of morbidity and mortality. Weight management can reduce the risk of complications and improve the quality of life of patients with obesity. This study explored primary care physicians' (PCPs') attitudes and knowledge about weight management. METHODS: An anonymous questionnaire was distributed to 400 PCPs between 2020 and 2021. The survey included questions on treatment approaches (pharmaceutical and surgical) and items regarding the respondents' demographic characteristics. We compared PCPs with low or high proactivity toward weight management. We explored attitudes and knowledge with the chi-square test for categorical variables or the Mann-Whitney test for continuous variables. RESULTS: A total of 145 PCPs answered our survey (a response rate of 36.25%). More than half (53.8%) of the respondents showed low proactivity toward weight management in their practice. Proactive respondents were more likely to believe that pharmaceutical treatment effectively reduces weight and offered medical and surgical treatment options more frequently to their patients. Lack of knowledge was the most predominant reason for PCPs avoiding offering treatment to their patients, especially in less proactive PCPs (33.3% vs. 5.3%, p-value < 0.001). When comparing different pharmaceutical options, 46.6% of PCPs report they tend to prescribe liraglutide to their patients compared with only 11% who prescribe orlistat and 10.3% who prescribe phentermine (p-value < 0.001). CONCLUSIONS: Many PCPs still do not actively provide obesity treatment despite improved awareness and therapeutic options. PCPs' proactivity and attitudes are vital to this effort.

Physical work environment and burnout among primary care physicians in Israel: a cross-sectional study.

BACKGROUND: Physician burnout remains a prevalent issue globally, negatively affecting work satisfaction and patient care. However, exploration of the physical work environments of physicians, a potential influencing factor for burnout, remains scarce. The physical work environment is everything that surrounds the physician, including the doctor's office, the clinic, the clinic's building, the waiting, and staff rooms. The aims of this study were to describe aspects of the physical work environment of primary care physicians (PCPs) and to explore the association between the physical work environment and burnout. METHODS: In this cross-sectional study, we emailed questionnaires to an online community of PCPs in Israel in October 2021. We asked physicians about their satisfaction with their physical work environment, evaluated elements of the work environment, and assessed burnout status (with the Shirom-Melamed Burnout Measure, SMBM). We used the Chi-square and Mann-Witney tests to compare categorical and continuous variables and used logistic regression for the final model. RESULTS: Two hundred twenty-one PCPs answered the questionnaire (27.6% response rate). Over a third (35.7%) of respondents reported high burnout. PCPs who were satisfied with their general physical environment had lower burnout rates than those who were unsatisfied (28.1% vs. 47.8%, p-value < 0.001). We found positive correlations between general satisfaction with the physical work environment and the scores achieved for the doctor's office, the clinic, the clinic's building, and the waiting room. In the multivariate analysis, high satisfaction with the general physical work environment was associated with decreased odds for burnout (OR-0.50, 95% CI 0.25-0.99, p-value-0.048). CONCLUSION: The doctor's office, the clinic, the clinic's building, and the waiting room affected general satisfaction from the physical work environment. High satisfaction with the physical work environment reduced burnout rates. Future studies are needed to determine whether PCPs and managers should invest in the physical work environment to decrease burnout and increase satisfaction.

Common Bacterial Infections during the 3-Month Period after SARS-CoV-2 Infection: A Retrospective Cohort Study.

INTRODUCTION: Correlations between SARS-CoV-2 and bacterial infections have mainly been studied in hospitals, and these studies have shown that such interactions may be lethal for many. In the context of community flora, less is known of the trends and consequences of viral infections relative to subsequent bacterial infections. PURPOSE: This study aims to explore the prevalence and characteristics of bacterial infections in the three months following SARS-CoV-2 infections, in a community, real-world setting. METHODS: In this retrospective cohort study, we compared patients who completed a polymerase chain reaction (PCR) test or an antigen test for SARS-CoV-2 during January 2022, the peak of the Omicron wave, and examined bacterial infections following the test. We searched these cases for diagnoses of the following four bacterial infections for three months following the test: Group A Streptococcus (GAS) pharyngitis, pneumonia, cellulitis, and urinary tract infections (UTI). RESULTS: During January 2022, 267,931 patients tested positive and 261,909 tested negative for SARS-CoV-2. Test-positive compared to test-negative patients were significantly younger (42.5 years old vs. 48.5 years old, p < 0.001), smoked less, and had fewer comorbidities (including ischemic heart disease, diabetes mellitus, hypertension, chronic obstructive pulmonary disease, and chronic renal failure). In the multivariable analysis, test-positive patients had an increased risk for GAS pharyngitis (adjusted odds ratio [aOR] = 1.25, 95% CI 1.14-1.38, p-value < 0.001) and pneumonia (aOR = 1.25, 95% CI 1.15-1.35, p-value < 0.001), a trend towards an increased prevalence of UTI (aOR = 1.05, 95% CI 0.99-1.12, p-value = 0.092), and lower risk for cellulitis (aOR = 0.92, 95% CI 0.86-0.99, p-value < 0.05). CONCLUSIONS: A history of SARS-CoV-2 infection in the past three months increased susceptibility to respiratory tract bacterial infections and the prevalence of UTI.

Smoking cessation - better together: A retrospective cohort study.

INTRODUCTION: Smoking is the leading preventable cause of death and illness globally. There is conflicting evidence regarding the association between quitting rates and partners' smoking status. It is thought that spouses influence one another's health habits, including smoking. This study aims to evaluate this association in patients who made a smoking cessation attempt with pharmacotherapy. METHODS: For this Israeli nationwide retrospective cohort study, we randomly selected patients who filled a prescription for varenicline as part of their smoking cessation process and were partnered. The participants were asked to complete a questionnaire 26-52 weeks after the first varenicline purchase. The independent variables were the partner's smoking status at the beginning of the smoking cessation process and while answering the questionnaire. The outcome was a success in the quitting process. RESULTS: In all, 226 (50%) participants had partners who smoked at the beginning of the quitting process, and 230 (50%) had non-smoking partners; 178 (39%) participants reported successful smoking cessation. There was a significant difference in success rates depending on partners' smoking status at the end of the process, with success rates of 39% with a non-smoking partner, 76% with a partner who also stopped smoking, and 31% with a partner who continued smoking (p<0.001). Multivariate analysis showed that having a partner who stopped smoking during the quitting process was associated with higher odds of quitting compared with having a non-smoking partner (OR=4.73; 95% CI: 1.86-12.05). CONCLUSIONS: This study showed that both partners quitting was associated with increased odds of successful quitting. Health providers should make efforts to engage both partners in smoking cessation.

Aerobic bacteria produce nitric oxide via denitrification and promote algal population collapse.

Microbial interactions govern marine biogeochemistry. These interactions are generally considered to rely on exchange of organic molecules. Here we report on a novel inorganic route of microbial communication, showing that algal-bacterial interactions between Phaeobacter inhibens bacteria and Gephyrocapsa huxleyi algae are mediated through inorganic nitrogen exchange. Under oxygen-rich conditions, aerobic bacteria reduce algal-secreted nitrite to nitric oxide (NO) through denitrification, a well-studied anaerobic respiratory mechanism. The bacterial NO is involved in triggering a cascade in algae akin to programmed cell death. During death, algae further generate NO, thereby propagating the signal in the algal population. Eventually, the algal population collapses, similar to the sudden demise of oceanic algal blooms. Our study suggests that the exchange of inorganic nitrogen species in oxygenated environments is a potentially significant route of microbial communication within and across kingdoms.

Direct and Indirect Predictors of Medication Adherence With Bipolar Disorder: Path Analysis.

BACKGROUND: Despite the efficacy of treatment and severity of symptoms, medication adherence by many with bipolar disorder (BD) is variable at best. This poses a significant challenge for BD care management. OBJECTIVE: For this study, we set out to identify psychosocial and psychiatric predictors of medication adherence with BD. METHODS: Using microtargeted social media advertising, we recruited an international sample of young and older adults with BD living in North America (Canada and the United States), Western Europe (eg, United Kingdom and Ireland), Australia and New Zealand (N=92). On average, participants were 55.35 (SD 9.65; range 22-73) years of age, had been diagnosed with BD 14.25 (SD 11.14; range 1-46) years ago, and were currently prescribed 2.40 (SD 1.28; range 0-6) psychotropic medications. Participants completed questionnaires online including the Morisky Medication Adherence Scale. RESULTS: Medication adherence did not significantly differ across BD subtypes, country of residence, or prescription of lithium versus other mood stabilizers (eg, anticonvulsants). Path analyses indicate that alcohol misuse and subjective or perceived cognitive failures are direct predictors of medication adherence. BD symptoms, psychological well-being, and the number of comorbid psychiatric conditions emerged as indirect predictors of medication adherence via perceived cognitive failures. CONCLUSIONS: Alcohol misuse did not predict perceived cognitive failures. Nor did age predict medication adherence or cognitive failures. This is noteworthy given the 51-year age range of participants. That is, persons in their 20s with BD reported similar levels of medication adherence and perceived cognitive failures as those in their 60s. This suggests that perceived cognitive loss is a facet of adult life with BD, in contrast to the assumption that accelerated cognitive aging with BD begins in midlife.

Social Media Use and Well-being With Bipolar Disorder During the COVID-19 Pandemic: Path Analysis.

BACKGROUND: Reliable and consistent social support is associated with the mental health and well-being of persons with severe mental illness, including bipolar disorder (BD). Yet the COVID-19 pandemic and associated social distancing measures (eg, shelter in place) reduced access to regular social contacts, while social media use (SMU) increased concomitantly. Little is currently known about associations between the well-being of adults with BD and different types of SMU (eg, passive and active). OBJECTIVE: For this study, we had two goals. First, we report descriptive information regarding SMU by persons with BD during COVID-19 (all platforms). Specific to Facebook, we next developed and tested a hypothesized model to identify direct and indirect associations between BD symptoms, social support, loneliness, life satisfaction, and SMU. Responses were collected during the global spread of the Delta variant and prior/concurrent with the Omicron variant, 20 months after the World Health Organization declared COVID-19 a global pandemic. METHODS: Over 8 weeks, we obtained responses from an international sample of 102 adults with BD using the Qualtrics online platform. Most had previously participated in the BADAS (Bipolar Affective Disorders and older Adults) Study (n=89, 87.3%); the remainder were recruited specifically for this research (n=13, 2.7%). The subsamples did not differ in age (t100=1.64; P=.10), gender (χ22=0.2; P=.90), socioeconomic status (χ26=9.9; P=.13), or time since BD diagnosis (t97=1.27; P=.21). Both were recruited using social media advertising micro-targeted to adults with BD. On average, participants were 53.96 (SD 13.22, range 20-77) years of age, they had completed 15.4 (SD 4.28) years of education, and were diagnosed with BD 19.6 (SD 10.31) years ago. Path analyses were performed to develop and test our hypothesized model. RESULTS: Almost all participants (n=95, 93.1%) reported having both Facebook and LinkedIn accounts; 91.2% (n=93) reported regular use of either or both. During the pandemic, most (n=62, 60.8%) reported accessing social media several times a day; 36.3% (n=37) reported using social media more often since the emergence of COVID-19. Specific to Facebook, the model we hypothesized differed somewhat from what emerged. The resulting model suggests that symptoms of depression predict loneliness and, inversely, social support and life satisfaction. Social support predicts social Facebook use, whereas passive Facebook use predicts life satisfaction. Symptoms of depression emerged as indirect predictors of SMU via social support. CONCLUSIONS: Our findings suggest that the operational definition of passive-active SMU requires further analysis and refinement. In contrast to theory, passive Facebook use appears positively associated with well-being among certain populations. Longitudinal data collection over multiple points is required to identify associations between BD symptoms, SMU, and well-being over time.

Co-transport of the nuclear-encoded Cox7c mRNA with mitochondria along axons occurs through a coding-region-dependent mechanism.

Nuclear-encoded mitochondrial protein mRNAs have been found to be localized and locally translated within neuronal processes. However, the mechanism of transport for those mRNAs to distal locations is not fully understood. Here, we describe axonal co-transport of Cox7c with mitochondria. Fractionation analysis and single-molecule fluorescence in situ hybridization (smFISH) assay revealed that endogenous mRNA encoding Cox7c was preferentially associated with mitochondria in a mouse neuronal cell line and within mouse primary motor neuron axons, whereas other mRNAs that do not encode mitochondrial protein were much less associated. Live-cell imaging of MS2-tagged Cox7c mRNA further confirmed the preferential colocalization and co-transport of Cox7c mRNA with mitochondria in motor neuron axons. Intriguingly, the coding region, rather than the 3' untranslated region (UTR), was the key domain for the co-transport. Our results reveal that Cox7c mRNA can be transported with mitochondria along significant distances and that its coding region is a major recognition feature. This is consistent with the idea that mitochondria can play a vital role in spatial regulation of the axonal transcriptome at distant neuronal sites.

Early Detection of Grapevine (Vitis vinifera) Downy Mildew (Peronospora) and Diurnal Variations Using Thermal Imaging.

Agricultural industry is facing a serious threat from plant diseases that cause production and economic losses. Early information on disease development can improve disease control using suitable management strategies. This study sought to detect downy mildew (Peronospora) on grapevine (Vitis vinifera) leaves at early stages of development using thermal imaging technology and to determine the best time during the day for image acquisition. In controlled experiments, 1587 thermal images of grapevines grown in a greenhouse were acquired around midday, before inoculation, 1, 2, 4, 5, 6, and 7 days after an inoculation. In addition, images of healthy and infected leaves were acquired at seven different times during the day between 7:00 a.m. and 4:30 p.m. Leaves were segmented using the active contour algorithm. Twelve features were derived from the leaf mask and from meteorological measurements. Stepwise logistic regression revealed five significant features used in five classification models. Performance was evaluated using K-folds cross-validation. The support vector machine model produced the best classification accuracy of 81.6%, F1 score of 77.5% and area under the curve (AUC) of 0.874. Acquiring images in the morning between 10:40 a.m. and 11:30 a.m. resulted in 80.7% accuracy, 80.5% F1 score, and 0.895 AUC.

Opioid sparing effect of ketamine in military prehospital pain management-A retrospective study.

BACKGROUND: Opioids are the most commonly used analgesics in acute trauma, but are limited by slow onset and significant adverse effects. Ketamine is an effective and widely used analgesic. This study was aimed to evaluate the effectiveness and opioid-sparing effects of ketamine when used in prehospital military trauma setting. METHODS: A retrospective analysis of a prehospital military trauma registry between 2014 and 2020. Inclusion criteria were 16 years or older, two or more documented pain assessments, at least one indicating severe pain, and administration of opioids and/or low-dose ketamine. Joint hypothesis testing was used to compare casualties who received opioids only to those who received ketamine on outcomes of pain score reduction and opioid consumption. RESULTS: Overall, 382 casualties were included. Ninety-one (24%) received ketamine (21 as a single analgesic), with a mean dose of 29 mg (standard deviation, 11). Mean reduction in pain scores (on an 11-point scale) was not significantly different; 4.3-point (2.8) reduction in the ketamine group and 3.7 points (2.4) in the opioid-only group ( p = 0.095). Casualties in the ketamine group received a median of 10 mg (interquartile range, 3.5-25) of morphine equivalents (MEs) compared with a median of 20 ME (10, 20) in the opioid-only group. In a multivariable multinomial logistic regression, casualties in the ketamine group were significantly more likely to receive a low (1-10 ME) rather than a medium (11-20 ME) dose of opioids compared with the opioid-only group (odds ratio, 0.032; 95% confidence interval, 0.14-0.75). CONCLUSION: The use of ketamine in the prehospital military setting as part of a pain management protocol was associated with a low rather than medium dose of opioids in a multivariable analysis, while the mean reduction in pain scores was not significantly different between groups. Using ketamine as a first-line agent may further reduce opioid consumption with a similar analgesic effect. LEVEL OF EVIDENCE: Therapeutic/care management; Level IV.

Primary Care Interventions to Address COVID-19 Vaccine Hesitancy Among Israel Defense Forces Soldiers.

Vaccine hesitancy is an obstacle to achieving high vaccination rates for COVID-19. Current knowledge on vaccine uptake is mostly based on hypothetical intention to vaccinate surveys. We compared intention to vaccinate and real-world vaccine uptake among 511 soldiers in a military unit during an unrestricted, on-site COVID-19 vaccine rollout. Soldiers were offered group lectures, on-site consultations and primary care office visits, discussing concerns on vaccination with a primary care physician. Overall, 359 (70.3%) soldiers participated in the group lectures, 33 (6.5%) in on-site consultations and 19 (3.7%) attended primary care visits. Overall, 459 (89.8%) of 511 soldiers vaccinated for COVID-19. Of the 90 soldiers initially refusing, 38 (42.2%) had agreed to receive a vaccine. On-site COVID-19 vaccine rollout joined with primary care communication interventions may maximize vaccine uptake within a young-adult community. Future studies should evaluate the effectiveness of these efforts across different populations in a controlled and comparative manner.

Localization and RNA Binding of Mitochondrial Aminoacyl tRNA Synthetases.

Mitochondria contain a complete translation machinery that is used to translate its internally transcribed mRNAs. This machinery uses a distinct set of tRNAs that are charged with cognate amino acids inside the organelle. Interestingly, charging is executed by aminoacyl tRNA synthetases (aaRS) that are encoded by the nuclear genome, translated in the cytosol, and need to be imported into the mitochondria. Here, we review import mechanisms of these enzymes with emphasis on those that are localized to both mitochondria and cytosol. Furthermore, we describe RNA recognition features of these enzymes and their interaction with tRNA and non-tRNA molecules. The dual localization of mitochondria-destined aaRSs and their association with various RNA types impose diverse impacts on cellular physiology. Yet, the breadth and significance of these functions are not fully resolved. We highlight here possibilities for future explorations.

OPPORTUNISTIC EVALUATION OF BONE MINERAL DENSITY BY PET-CT IN HODGKIN LYMPHOMA PATIENTS.

Objective: Bone density loss and increased risk for osteoporosis are of concern in Hodgkin lymphoma (HL) patients. Routinely performed positron emission tomography-computed tomography (PET-CT) scans could be informative in assessing bone mineral density (BMD). Methods: This retrospective study included 80 adults with newly diagnosed HL treated with standard first-line chemotherapy regimens. PET-CT scans performed at diagnosis (PET-CT1), at the end of chemotherapy (PET-CT2), and at follow-up after remission (PET-CT3) were used to assess BMD changes by measuring lumbar vertebrae CT attenuation. A CT attenuation threshold of 160 Hounsfield units was used to define abnormal BMD. Results: Following chemotherapy, comparison of PET-CT2 with PET-CT1 revealed a mean (standard deviation) 14.2% (10.4%) BMD reduction (P<.001). On PET-CT3 performed at 14.6 (3.25) months after the last course of chemotherapy, a slight improvement (4.6% [10.4%]) in comparison to PET-CT2 was noted. Twelve patients (15%) converted from normal baseline BMD on PET-CT1 to abnormal BMD after chemotherapy on PET-CT2. Age, baseline BMD, and steroid cumulative dose were associated with BMD decline and risk for abnormal BMD after chemotherapy. No clinical fractures were reported, and only one rib fracture was incidentally captured (1.25%). Conclusion: HL patients treated with common first-line chemotherapies demonstrate a significant decline in bone density on routine PET-CT scans. Opportunistic use of PET-CT scan has the potential to detect HL patients at high risk for developing osteoporosis and to guide clinicians regarding monitoring and intervention. Abbreviations: BMD = bone mineral density; CT = computed tomography; DXA = dual-energy X-ray absorptiometry; HL = Hodgkin lymphoma; HU = Hounsfield units; L = lumbarvertebra; PET-CT = positron emission tomography-computed tomography; T = thoracic vertebra.

Erythrokeratodermia variabilis with erythema gyratum repens-like lesions.

A large pedigree with erythrokeratodermia variabilis (EKV) and erythema gyratum repens-like lesions is described. Clinical, laboratory, and histologic findings of this family are presented. The differential diagnoses of the following dermatoses with an erythematous and a hyperkeratotic component are discussed: erythrokeratodermia variabilis (Mendes da Costa), progressive symmetric erythrokeratoderma (Gottron), loricrin keratoderma, erythrokeratoderma en cocardes (Degos), Netherton syndrome, keratitis-ichthyosis-deafness (KID) syndrome, erythrokeratolysis hiemalis (Oudtshoorn disease), and nonbullous congenital ichthyosiform erythroderma.
