Screening for second malignancies in mycosis fungoides: non-Hodgkin lymphoma, Hodgkin lymphoma, lung cancer, bladder cancer and melanoma

BACKGROUND

Patients with mycosis fungoides (MF) are at increased risk of developing non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), lung cancer, bladder cancer and melanoma. The characteristics of patients developing these malignancies have not been specifically delineated. In addition, there are no established guidelines for screening MF patients for second malignancies.

MATERIALS/METHODS

We identified 742 patients with MF who developed second malignancies in the Surveillance Epidemiology and End Result-18 database.

RESULTS

The majority of second malignancy patients were white and male, mean age 55-67 years at diagnosis of MF, and mean age 61-72 years at diagnosis of second malignancy. The majority of patients diagnosed with second malignancies had early stage MF. MF patients with NHL, lung cancer, and bladder cancer tended to be diagnosed at earlier stages of the second malignancy than patients without MF and demonstrated better 5-year overall survival. There was no improvement in stage at diagnosis or survival for MF patients who were diagnosed with melanoma compared to patients without MF.

CONCLUSIONS

Improvements in survival in MF/NHL, MF/lung cancer and MF/bladder cancer patients may reflect differences in disease biology secondary to having MF or the importance of increased contact with the healthcare system. MF/melanoma data suggest that patients require regular pigmented-lesion-focused skin examinations. Tools for screening include regular lymph node examinations, pigmented-lesion-focused examinations and detailed review of systems questions. Smoking cessation counseling is key intervention in this population, as is ensuring that all age- and sex-specific cancer screenings are up-to-date (e.g. lung cancer screening, mammography, and colonoscopy). The utility of regular imaging for second malignancy screening and lab testing such as routine urinalysis requires additional study and expert consensus.

Reducing admission hypothermia in newborns at a tertiary care NICU of northern India: A quality improvement study

BACKGROUND

Hypothermia at admission to neonatal intensive care units (NICU) is associated with increased morbidity and mortality in newborns. A baseline study at a tertiary care hospital with all out-born babies showed admission hypothermia of 82%.

OBJECTIVE

To reduce admission hypothermia (moderate) in newborns at least by 50% in next 6 months.

METHODS

A quality improvement (QI) study was planned using WHO Point of Care Quality Improvement Model (POCQI), [17] using PDSA (Plan-Do-Study-Act) cycle approach from April 2018 to March 2019, and including 427 term and preterm babies. We educated the staff, reinforced the use of caps, cling wraps, warm linen, introduced Ziploc bags and ensured adequate use of transport incubator.

RESULTS

After 6 months, overall admission hypothermia decreased from 82% to 45%, moderate hypothermia reduced from 46% to <10% (P < 0.001) and severe hypothermia (3%) was completely eliminated. There was also significant reduction in incidence of Intraventricular hemorrhage (13% Vs 4.7%), Late onset neonatal sepsis (38% Vs 19%) and metabolic acidosis (43% Vs 28%). We were able to sustain this improvement for the next 6 months and is ongoing. The strongest predictor of hypothermia was newborns being in the phase before QI initiative was started (OR 2.36, 95% CI 1.47, 3.23).

CONCLUSION

This study is a cost effective approach in reducing admission hypothermia in NICU in a resource limited setting with all outborn babies, and further decreasing the morbidity associated with it. Hence, emphasizing the importance of maintaining euthermia, not only in delivery rooms, but also during transportation.

High burden of cardiometabolic risk factors in spouses of Indian women with hyperglycaemia in pregnancy

AIM

To evaluate the burden and association of cardiometabolic risk factors in the spouses of women with and without hyperglycaemia in pregnancy.

METHODS

Women with (n = 204) and without (n = 197) hyperglycaemia in pregnancy, along with their spouses, participated in this cross-sectional study. The hyperglycaemia in pregnancy group included women with gestational diabetes and diabetes in pregnancy. A detailed questionnaire was completed for all participants (men and women), documenting relevant personal and medical history, along with biochemical investigations (men).

RESULTS

A total of 401 couples were evaluated at the time point during the pregnancy of 24.7 ± 5.2 gestational weeks (mean ± sd). Dysglycaemia (prediabetes or diabetes), overweight/obesity (BMI ≥25 kg/m² ) and metabolic syndrome were detected in 120 (58.9%), 123 (60.3%) and 98 spouses (48.3%) of women with hyperglycaemia in pregnancy, respectively. In the fully adjusted model, an increased risk of dysglycaemia [odds ratio 1.43 (95% CI 0.95-2.17); P = 0.088], overweight/obesity [odds ratio 1.49 (95% CI 0.98-2.27); P = 0.064] and metabolic syndrome [odds ratio 2.00 (95% CI 1.30-3.07); P = 0.001] was seen in the spouses of women with hyperglycaemia in pregnancy. The prevalence of these metabolic conditions was higher in spouses of women with diabetes in pregnancy compared to spouses of women with gestational diabetes mellitus.

CONCLUSIONS

A high burden of cardiometabolic risk factors was observed in the spouses of women with hyperglycaemia in pregnancy. The opportunity provided by pregnancy could be used by the healthcare system not only to improve the health of the woman and her offspring, but also her spouse.

Cardiological society of India document on safety measure during echo evaluation of cardiovascular disease in the time of COVID-19

An echocardiographic investigation is one of the key modalities of diagnosis in cardiology. There has been a rising presence of cardiological comorbidities in patients positive for COVID-19. Hence, it is becoming extremely essential to look into the correct safety precautions, healthcare professionals must take while conducting an echo investigation. The decision matrix formulated for conducting an echocardiographic evaluation is based on presence or absence of cardiological comorbidity vis-à-vis positive, suspected or negative for COVID-19. The safety measures have been constructed keeping in mind the current safety precautions by WHO, CDC and MoHFW, India.

Mycosis fungoides: developments in incidence, treatment and survival

BACKGROUND

Prior studies have demonstrated improved disease-specific survival of mycosis fungoides (MF) patients over the last 50 years.

OBJECTIVE

To analyse patterns of survival and incidence from 1973 to 2016 and determine whether apparent improvements in MF-specific survival are due to lead-time bias rather than improvements in treatment.

METHODS

We performed an analysis of 10 155 patients diagnosed with MF from 1973 to 2016 in the United States cancer registries of SEER-18. We also performed a literature review of papers including stage data for unselected populations of MF patients prior to 2000.

RESULTS

Incidence of MF increased from 3.0 per million person-years in the 1970s to 5.9 in the 2010s. For all cohorts, non-Hodgkin lymphoma (including MF) was the leading cause of death. Survival analysis demonstrated marked improvement in disease-specific and overall survival from the 1970s to 2010s. Based on systematic review of the literature, 32%-73% of patients diagnosed prior to 2000 were diagnosed with early-stage disease, as opposed to 81% of patients in the SEER 2000-2016 cohort (P < 0.035 for all cohorts).

CONCLUSIONS

Although there have been improvements in MF-related survival over the last 50 years, these may reflect improvements in our ability to diagnose early-stage disease rather than improved treatment.

Hof1 plays a checkpoint-related role in MMS-induced DNA damage response in Candida albicans

Cells depend on robust DNA damage recognition and repair systems to maintain genomic integrity for survival in a mutagenic environment. In the pathogenic yeast Candida albicans, a subset of genes involved in the response to DNA damage-induced genome instability and morphological changes has been found to regulate virulence. To better understand the virulence-linked DNA repair network, we screened for methyl methane sulfonate (MMS) sensitivity within the GRACE conditional expression collection and identified 56 hits. One of these potential DNA damage repair-associated genes, a HOF1 conditional mutant, unexpectedly had a previously characterized function in cytokinesis. Deletion of HOF1 resulted in MMS sensitivity and genome instability, suggesting Hof1 acts in the DNA damage response. By probing genetic interactions with distinct DNA repair pathways, we found that Hof1 is genetically linked to the Rad53 pathway. Furthermore, Hof1 is down-regulated in a Rad53-dependent manner and its importance in the MMS response is reduced when Rad53 is overexpressed or when RAD4 or RAD23 is deleted. Together, this work expands our understanding of the C. albicans DNA repair network and uncovers interplay between the cytokinesis regulator Hof1 and the Rad53-mediated checkpoint.

Knowledge of Australian primary education providers towards dental avulsion injuries: a cross-sectional study

BACKGROUND/AIM

The aim of this study was to evaluate the knowledge of school professionals regarding the emergency management of dental avulsion.

METHODS

This cross-sectional study utilised a self-administered, pilot-tested questionnaire for school staff from primary schools. Descriptive statistics were used for the analysis - the prevalence and univariate associations between a categorical outcome and the variables under consideration, were evaluated using Pearson's Chi-squared test.

RESULTS

This survey yielded a response rate of 43.5% (n = 313). Approximately 60% of participants held valid first-aid certificates and 23% had received avulsion advice previously. Over 80% of participants expressed an unwillingness to replant an avulsed tooth, and over 90% believed that there should be greater awareness in this area. This unwillingness to replant was influenced by respondents' age (x2 = 8.13 df = 3, P = 0.043) and receiving advice previously (x2 = 13.15, df = 1, P < 0.001). Under-preparedness was related to years of experience (x2 = 15.03, df = 5, P = 0.010), first-aid training (x2 = 6.41, df = 1, P = 0.011) and receiving advice previously (x2 = 43.47, df = 1, P < 0.001). It was also evident that first-aid training positively influenced appropriate dental referral in the management pathway (x2 = 10.49, df = 1, P = 0.001).

CONCLUSION

This study suggests that there is an inadequate level of knowledge on the appropriate management of dental avulsion injuries amongst primary school professionals in Australia.

Use of Fluoridated Dentifrices among Children: Are We in the Right Direction?

Introduction Use of topical fluorides in dentifrices has always been an important tool in prevention of dental caries in young children. Due to the easy availability of various low and high fluoride dentifrices, the parents have no clear understanding about their correct age-appropriate use in children. This study was undertaken to evaluate and understand the trend and current practices among the end user.

Materials and Methods A total of 173 children aged 4 to 6 years were enrolled in the study from schools located in two different geographical areas of the Chandigarh city; group 1 (n = 90) from a peri-urban slum cluster: (Govt. Primary School, Indira Colony, Mani Majra, n = 51); Govt. Middle School, Mani Majra (n = 39); group 2 (n = 83) from an urban private city school (Ankur, Punjab University, Sector 14) using cluster sampling method. Two examiners using type IV examination examined all the children aged 4 to 6 years present using a preinstructed close-ended questionnaire. Data were analyzed using SPSS Software Version 25 (SPSS Inc., Chicago, IL, United States).

Results The data regarding the knowledge of fluoride in pastes showed that 85% of the children were using high fluoride pastes, 10% were using nonfluoride pastes, and 5% were using low fluoride pastes. In group 1, none of the users were aware about the benefits/risk of using fluoride toothpastes and only 22% were aware in group 2. Only 27% of children in group 1 dispensed the correct amount of dentifrice for this age group i.e., a pea head size versus 67% in group 2; a half brush length was dispensed by 61.5% in group 1 and 28% in group 2, and just a smudge by 11.5% in group 1 and 5% in group 2. Forty one percent children in both the groups had a history of having intentionally consumed the toothpaste. The toothpaste was dispensed to the child by parent in 89% of cases in group 2 and only 50% in group 1 and 88% parents claimed to always supervise the child while tooth brushing versus only 53% in group 1. Majority of the respondents’, i.e., 97% in group 1 and 63% in group 2 had never been explained about the correct method of use of fluoride paste in children.

Conclusion Knowledge about fluoridated toothpastes is low among the population. The children in peri-urban slums areas are exposed to the high fluoride pastes from very early in life and there is no other toothpaste which is brought home except for those which are commonly used among the members. In the city schools; however, a small percentage of population uses low fluoride pastes in children, possibly due to a greater awareness and access to information, but has no clear idea about their limitations and benefits of age-appropriate use. Till appropriate guidelines are available for the country, a safe practice to follow is tailoring individual need based protocol. The children in peri-urban slums areas need to be educated more on the health practices and importance of use of fluoride dentifrices and the children in the city schools need to be guided more on the age appropriate use of high and low fluoride dentifrices.

Efficacy of electromotive drug administration in delivering botulinum toxin a in children with neuropathic detrusor overactivity-outcomes of a pilot study

BACKGROUND

Intravesical botulinum toxin A (BtA) injection is well established in managing paediatric neuropathic detrusor overactivity (NDO). Electromotive drug administration (EMDA) is a less invasive method, which can be performed in the clinic, using pulsed electrical current for drug delivery via a urethral catheter. Few small studies report good outcomes following BtA via EMDA (BtA/EMDA) into bladders of children with NDO.

OBJECTIVE

The objective of this study is to assess the efficacy of BtA/EMDA in children with NDO, reduced bladder capacity and compliance.

METHODS

Twelve children with NDO on baseline urodynamic study were prospectively included. Pre-BtA/EMDA and post-BtA/EMDA results compared the following four parameters: maximal cystometric capacity, bladder compliance, maximal detrusor pressure (pDetmax) during detrusor overactivity and pDetmax at capacity. The Wilcoxon matched-pairs signed-rank test using Graphpad Prism 8 was used for analysis. Secondary outcomes include adverse effects and symptomatic improvement.

RESULTS

Fourteen episodes of BtA/EMDA were performed. Five patients received 3.3 IU/kg of Botox®, and five received 10 IU/kg (maximum 300 IU). Four patients received 10 IU/kg of Dysport®. Two patients in the Dysport®/EMDA group also received Botox®/EMDA more than six months previously. Thirteen of 14 post-EMDA results were completed and included in the paired analysis. No statistically significant improvements in any cystometric parameters were demonstrated. Eight patients subsequently had intravesical BtA injections with significant improvements in both cystometric parameters and symptoms. Two patients subsequently transitioned to adult services; one was commenced on mirabegron, and one has undergone ileocystoplasty with Mitrofanoff appendicovesicostomy.

DISCUSSION

Despite some evidence to support BtA/EMDA in children with NDO, the authors were unable to replicate previously published positive cystometric and symptomatic outcomes. In addition, BtA/EMDA performed poorly when compared with conventional intravesical BtA injections. This implies failure of EMDA to deliver BtA correctly to the target tissue. The large size of the BtA molecule or the abnormal bladder wall in NDO could account for the negative results. Thorough preparation and consultation was undertaken before this study with BtA/EMDA, and it is discouraging that the authors were unable to reproduce the positive results of other groups.

CONCLUSIONS

Although safe and acceptable to most patients, the authors cannot recommend the use of BtA/EMDA for NDO in children at present.

P4632Impact of intracardiac thrombosis in patients with acute myocardial infarction: insights from nationwide inpatient sample in the United States

Background

Intracardiac thrombosis (ICT) is a complication of Acute myocardial infarction (AMI).

Hypothesis

Our aim was to evaluate the impact of ICT on mortality, thromboembolism, length of stay in patients with AMI.

Methods

Data was collected from the Nationwide Inpatient Sample (NIS) for the year 2016, where patients with a primary diagnosis of ICT as a complication of AMI (ICD10-CM code I23.6) were included. Comparisons were made between patients with ICT post-AMI (ICD10-CM code I23.6) vs those with AMI (ICD10-CM I21.0).

Results

Of a total of 200930 cases of AMI, 488 (0.5%) had ICT. The patients with ICT had an increased length of stay (LOS) (8.5±9.8 vs 5.7±7.4 days; p<0.001), increased ischemic stroke (10.6% vs 2.9%; p<0.001), and cardiogenic shock (15% vs 7%; p<0.001). There was no difference in mortality between the groups.

Table 1. Patient characteristics AMI% (n=200,930) ICT post AMI% (n=488) p-values Demographic variables   a. Males 59 73   b. Females 41 27 <0.001 Race   a. Caucasian 71 68 0.10   b.

Conclusion

ICT as a complication of AMI is associated with increased hospital LOS and adverse events.

Prevalence, defect characteristics and distribution of other phenotypes in 3- to 6-year-old children affected with Hypomineralised Second Primary Molars

PURPOSE

To assess the prevalence, severity and defect characteristics of hypomineralised second primary molars in schoolgoing children along with distribution of other phenotypes.

METHODS

A total of 3013, 3- to 6-year-old children were examined for the presence of hypomineralised second primary molars (HSPMs) using an adapted version of EAPD Criteria (2003). The molars were evaluated for the presence, location and colour of demarcated opacities along with associated post-eruptive breakdown (PEB) and atypical restorations. A thorough examination of the entire dentition was followed for evaluation of teeth other than primary second molars for the presence of similar hypomineralised defects. Data were analysed using Chi Square, Fisher exact's and Mann-Whitney U tests at α = 0.05.

RESULTS

A total of 3013 out of 3200 children were included having a mean age of 4.25 ± 0.5 years and deft of 2.1 ± 0.5. Using the adapted version of EAPD 2003 criteria for MIH, the children were evaluated for the presence of hypomineralised second primary molars, the prevalence of which was found to be 7.9%. Hypomineralisation defects were more commonly observed in the maxillary arch (53.4% vs. 42.8%, p = 0.04) with creamish white opacities involving the buccal and lingual surfaces being the most common defects (43.6%). The mean number of HSPMs per child was 1.9. Other phenotypes included demarcated opacities majorly on primary canines (6.6%) followed by primary first molars (4.6%).

CONCLUSIONS

Hypomineralised primary second molars are a fairly common condition affecting approximately 7.9% of the population thus warranting early recognition and management.

Parental home removal of urethral catheters after urological surgery-a prospective benchmarking study

INTRODUCTION

Many urological operations require placement of a urethral Foley catheter. The catheter often needs to remain in situ for a period of time after discharge; and patients subsequently require either a further hospital admission or community nurse review for catheter removal. Parents can easily remove the catheter at home by cutting the balloon port. This disrupts the valve and hence deflates the retaining balloon, thereby facilitating spontaneous passage of the catheter. The authors introduced this practice to their institution.

AIM

The aim was to assess safety and success of parental home catheter removal.

METHODS

A prospective data study was performed in a large pediatric urology center over a 12-month time period. Patients <16 years after single-stage hypospadias repair or other penile surgery were included on a voluntary basis. Parents of eligible patients were instructed verbally and with an information leaflet, including date for removal. Telephone follow-up after removal was undertaken to assess the outcome.

RESULTS

Thirty-eight patients were included over a 12-month time period. Patient age ranged from 9 months to 12 years (median age 2.5 years). The majority (82%) of patients had required a catheter after hypospadias repair. Home catheter removal was successful in 92% cases. Three children required professional support for catheter removal. Median time until catheter passage was 3 h (range 0-24 h). Considering that cost for day case admission for catheter removal averages at 130£ per patient, home catheter removal saved the NHS 4550£ in the time period.

DISCUSSION

This is the first study to report the safety and feasibility of parental home catheter removal by cutting the balloon port valve in the pediatric population. It offers a number of distinct advantages compared with traditional methods for removal. These include, namely, (i) positive patient experience: catheter removal in a familiar environment by a relative minimizes stressful experiences for the family; (ii) minimal trauma to healing tissues through spontaneous catheter passage; and (iii) health care-related cost savings. This was an initial benchmarking study, so patient numbers were relatively small. Nevertheless, it shows that the method is safe and received positive parental feedback.

CONCLUSION

Parental home removal of a urethral catheter is a feasible and safe alternative to catheter removal by a health-care professional. It minimizes parental anxiety and inconvenience related to the catheter removal appointment and allows for significant cost savings.
