Long-term effects of neonatal pain and sucrose treatment

Purpose

In neonatal intensive care units, applying sucrose solution for analgesia is now a routine treatment for mild procedural pain. Studies of animal and human infants provide clear evidence of benefits in the short term, but few studies have investigated the long term benefits. Thus, we determined whether sucrose could ameliorate painful stimulation during infancy in Sprague-Dawley rats and also explored the long-term effects of repeated sucrose administration during infancy. Female and male rats were included to investigate sex-related differences.

Methods

Rat pups were stimulated either with painful or tactile stimuli for the first 14 days of their lives. Pups were pretreated either with sucrose or not treated before stimulation. Behavioral tests were conducted during adolescence and adulthood. Hotplate, rotarod, open field, elevated plus maze, and radial arm water maze tests were employed to assess the behavioral consequences of early life manipulations and treatments.

Results

Painful stimulation during infancy increased the sensitivity to pain later in life, and sucrose did not remedy this effect. Motility, coordination, anxiety, and cognition tests in adulthood obtained mixed results. Pain during infancy appeared to increase anxiety during adulthood. Learning and memory in adulthood were affected by pain during infancy, and sucrose had a negative effect even in the absence of pain. No sex-related differences were observed in any of the behavioral tests by employing this model of neonatal pain.

Conclusion

Painful stimulation during infancy resulted in deficiencies in some behavioral tests later in life. Sucrose pretreatment did not mitigate these shortcomings and it actually resulted in negative outcomes.

Boosting the thermal management performance of a PCM-based module using novel metallic pin fin geometries: Numerical study

Satellite avionics and electronic components are getting compact and have high power density. Thermal management systems are essential for their optimal operational performance and survival. Thermal management systems keep the electronic components within a safe temperature range. Phase change materials (PCMs) have high thermal capacity, so they are promising for thermal control applications. This work adopted a PCM-integrated thermal control device (TCD) to manage the small satellite subsystems under zero gravity conditions thermally. The TCD's outer dimensions were selected upon a typical small satellite subsystem. The PCM adopted was the organic PCM of RT 35. Pin fins with different geometries were adopted to boost the lower thermal conductivity of the PCM. Six-pin fins geometries were used. First, the conventional geometries were square, circular, and triangular. Second, the novel geometries were cross-shaped, I-shaped, and V-shaped fins. The fins were designed at two-volume fractions of 20% and 50%. The electronic subsystem was assumed to be "ON" for 10 min releasing 20 W of heat, and "OFF" for 80 min. The findings show a remarkable decrease in the TCD's base plate temperature by 5.7 ℃ as the fins' number changed from 15 to 80 for square fins. The results also show that the novel cross-shaped, I-shaped, and V-shaped pin fins could significantly enhance thermal performance. The cross-shaped, I-shaped, and V-shaped reported a decrease in the temperature by about 1.6%, 2.6%, and 6.6%, respectively, relative to the circular fin geometry. V-shaped fins could also increase the PCM melt fraction by 32.3%.

Effects of an educational program on self-efficacy towards type 1 diabetes mellitus disease among parents and adolescents in Jordan

BACKGROUND

Type 1 diabetes mellitus is one of the most common childhood chronic diseases worldwide. In Jordan, the prevalence of type 1 diabetes mellitus is increasing rapidly over the last few years. Type 1 diabetes mellitus is a challenging disease since appropriate management of parents' and adolescents' diabetes requires knowledge, skills, and behavioral changes.

OBJECTIVES

To assess the effectiveness of a diabetes education program on self-efficacy towards type 1 diabetes mellitus among parents of young children and adolescents.

METHODS

A one-group pre-test-post-test study design was used. Participants registered in a diabetes education program and completed both pre-and post-test.

RESULTS

A total of 44 participants; 29 parents and 15 adolescents completed pre- and post-education tests. There was a statistically significant difference in the average mean score from the pre-test (M = 3.51, SD = 0.615) to the post-test [M = 4.22, SD = 0.484, t (43) =6.704, p < 0.000] for the self-efficacy scale, and overall self-efficacy scores were significantly improved after undertaking the education program.

CONCLUSION

Based on the findings, it is suggested that providing an evidence-based type 1 diabetes mellitus education program could significantly positively affect the self-efficacy of adolescents and parents of young children with type 1 diabetes mellitus.

RECOMMENDATION

Staff nurses should be competent enough to provide basic diabetic health education to the adolescents, parents, and caregivers of children with type 1 diabetes mellitus.

Cardiovascular Disease Risk Factors Awareness among Women with a History of Preeclampsia in Jordan

Introduction

Preeclampsia is a pregnancy-specific hypertensive disease that affects 3-5% of pregnant women all over the world and 1.3% of pregnancies among Jordanian women.

Objectives

This study aims to assess the cardiovascular disease risk factors awareness among women with a recent history of preeclampsia in Jordan and assess the role of healthcare providers in providing counseling about cardiovascular disease risk factors.

Methods

A descriptive cross-sectional design was used to recruit 180 women with a recent history of preeclampsia during the last 12 months. Data were obtained from patients' medical records and the Attitude and Beliefs about Cardiovascular Disease Risk Questionnaires.

Results

The results revealed that 43.9% of women with a recent history of preeclampsia have hypertension, 6.7% have diabetes mellitus, 16.1% have dyslipidemia, 28.9% have a family history of cardiovascular disease, 66.1% are overweight or obese, and 7.2% are smokers. The mean total score of knowledge subscale was 5.5 (SD  =  1.21) out of 8. Only 20% of the participants had good cardiovascular disease knowledge. The mean total score of risk perception was 15.47 (SD  =  7.8). The mean score of perceived benefits and intention to change behaviors was 2.30 (SD  =  0.62). The mean score of healthy eating intentions was 2.54 (SD  =  0.81). Income, having diabetes mellitus, and receiving counseling about preeclampsia as cardiovascular disease risk factor were associated with some dimensions of cardiovascular disease risk factors awareness.

Conclusion

The prevalence of cardiovascular disease risk factors was relatively high among the study participants. The majority of participants had inadequate cardiovascular disease knowledge. In addition, the role of healthcare providers in providing counseling about cardiovascular disease and related risk factors, including PE was limited. Providing more counseling related to cardiovascular disease by nurses and doctors is essential to enhance women's cardiovascular disease knowledge and intention to change lifestyle.

Home-Based Exercise to Improve Motor Functions, Cognitive Functions, and Quality of Life in People with Huntington's Disease: A Systematic Review and Meta-Analysis

Exercise in different settings has become a fundamental part of Huntington's disease (HD) management. The aim of this systematic review and meta-analysis was to investigate the effectiveness of home-based exercises (HBE) in HD. Randomized controlled trials (RCTs) investigating the effect of HBE on motor, cognitive, or health-related quality of life (QoL) outcomes in HD were included. Standardized mean difference (SMD), the 95% confidence interval, and p-values were calculated by comparing the outcomes change between HBE and control groups. Seven RCTs met the inclusion criteria. The included RCTs prescribed different types of HBEs, i.e., aerobic strengthening, walking, balance, and fine motor exercises. The HBE protocol length was between 6 and 36 weeks. The meta-analyses showed a significant effect of HBE intervention on motor function measure by Unified Huntington Disease Rating and overall QoL measure by Short Form-36 post-treatment respectively, [SMD = 0.481, p = 0.048], [SMD = 0.378, p = 0.003]. The pooled analysis did not detect significant changes in cognition, gait characteristics, or functional balance scales. The current study shows the positive effect of HBE in HD, especially on motor function and QoL. No significant adverse events were reported. The current results support the clinical effect of HBE intervention on motor function and QoL in HD patients. However, these results should be taken with caution due to the limited available evidence. Well-designed clinical studies that consider the disease severity and stages are required in the future.

The Difficulties in Emotional Regulation among a Cohort of Females with Lipedema

BACKGROUND

Lipedema is a chronic and progressive adipose tissue disorder that causes significant morbidity and negatively influences mental health and quality of life, and increases the risk of depression, anxiety, and eating disorders. One construct of relevance to better understanding psychological disorders is emotion regulation (ER). Therefore, the aim of this study is to investigate the difficulties in ER among lipedema patients compared to healthy people without lipedema.

METHODS

This cross-sectional study assessed differences in ER and anxiety between two groups: 26 female patients with lipedema and 26 sex- and age-matched healthy controls. The Difficulties in Emotion Regulation Scale (DERS) assessed emotional regulation across six dimensions: Impulse control, goal-directed behavior, awareness, clarity, non-acceptance, and strategies. Anxiety was assessed by the Hamilton Anxiety Scale (HAM-A). ANOVA assessed differences in measures between lipedema and healthy control groups.

RESULTS

Lipedema patients presented with significantly more difficulties in ER and a higher level of anxiety than those without lipedema. Specifically, the lipedema group showed higher and significant differences in total DERS and anxiety scores and all DERS subscales scores compared to those without lipedema.

CONCLUSIONS

Lipedema patients showed significant difficulties with ER, and were associated with anxiety symptoms, indicating that ER difficulties may play a role in developing emotional disorders, such as anxiety, for patients with lipedema. The health care provider should pay more attention to ER difficulties and psychological status among lipedema patients.

Effectiveness of non-pharmacological rehabilitation interventions in pain management in patients with multiple sclerosis: Systematic review and meta-analysis

BACKGROUND

Multiple sclerosis (MS) is a progressive inflammatory and autoimmune neurological disease caused by inflammation and demyelination of the central nervous system. Pain is a typical symptom of central nervous system demyelination, affecting 63% of adults with MS. Recently, the role of non-pharmacological pain management in patients is growing because the non-pharmacological interventions are considered safe, affordable, easy, and accessible. However, to date, no systematic reviews or meta-analyses have comprehensively examined the therapeutic effects of the variety of non-pharmacological therapeutic interventions in the management of pain in patients with MS.

OBJECTIVE

The study aimed to conduct a systematic review with meta-analysis to assess the effectiveness of the non-pharmacological rehabilitation interventions in pain management in patients with MS.

METHODS

A comprehensive search using PubMed, Cochrane, and Science Direct databases was performed and included all randomized controlled trials, randomized cross-over trials, and quasi-experimental trials assessing the effect of non-pharmacological interventions for managing pain in patients with MS. This study was conducted according to PRISMA guidelines of a systematic review and pair-wise meta-analysis. Meta-analyses were performed by calculating the standardized mean difference at a 95% confidence interval using Review Manager software.

RESULTS

Twenty-nine papers were included in the systematic review, and only 22 of them were included in the meta-analysis. The pooled analysis showed a significant effect of neuromodulation and transcranial direct current stimulation on pain intensity reduction in patients with MS (SMD -0.51, 95% CI -0.51 to -0.09, P = 0.02), (SMD -0.67, 95% CI -1.18 to -0.16 P = 0.01), respectively. The analysis showed significant improvement in pain intensity in patient with MS after mind-body therapies (SMD -0.45, 95% CI -0.82 to -0.7, P = 0.02), mindfulness (SMD -0.55, 95% CI -0.96 to -0.14, P = 0.009), hypnosis (SMD -0.88, 95% CI -1.30 to -0.46, P = 0.0001), trigger point therapies (SMD -0.83, 95% CI -1.65 to -0.01, P = 0.05) and cognitive behavioral therapy (SMD -0.64, 95% CI -1.18 to -0.11, P = 0.02). However, there is no significant effect of relaxation therapy on pain reduction in patients with MS (SMD -0.82, 95% CI -1.94 to 0.31, P = 0.15).

CONCLUSIONS

The results indicated that the majority of the non-pharmacological rehabilitation interventions showed potential therapeutic effects in reducing pain intensity in patients with MS.

Therapeutics effects of inhaled magnesium sulfate combined with adrenergic beta-2 agonist on children with acute asthma: Systematic review and meta-analysis

AIM

To review the evidence on the effectiveness of inhaled magnesium sulfate (MgSO4) combined with beta-2 (B2) agonist as compared to inhaled B2 agonist alone in treating pediatric patients with moderate to severe asthma attacks METHODS: The search was conducted on five electronic databases namely the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, PubMed, Science Direct, and Google Scholar.

RESULTS

Eight trials were included in the review. All studies involved a total of 1585 children aged 2-17 years with moderate to severe asthma attacks. The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials. Three studies that assessed the effect of inhaled MgSO4 as adjunctive therapy on vital signs revealed no effect of inhaled MgSO4 on vital signs (SMD -0.11, 95% CI 0.27-0.04, p = 0.16, I² = 68%). Two studies that assessed the effect of inhaled MgSO4 as adjunctive therapy on asthma severity score (ASS) revealed no effect of inhaled MgSO4 on ASS (SMD 0.22, 95% CI 0.01-0.44, Z = 2.01, p = 0.04, I² = 88%). Two studies that assessed the effect of inhaled MgSO4 as adjunctive therapy on peak expiratory flow rate (PEFR) revealed a large effect of B2 agonist alone on PEFR (SMD 2.02, 95% CI 0.83-3.2, p < 0.001, I² = 98%).

CONCLUSION

This review does not support the use of inhaled MgSO4 as adjunctive therapy to B2 agonist for asthmatic children.

Identification of Adolescents with Adiposities and Elevated Blood Pressure and Implementation of Preventive Measures Warrants the Use of Multiple Clinical Assessment Tools

The burden of abdominal adiposity has increased globally, which is recognized as a key condition for the development of obesity-related disorders among youth, including type 2 diabetes, cardiovascular disease, and hypertension. High blood pressure (BP) and cardiovascular diseases increase the rates of premature mortality and morbidity substantially. Aims: to investigate the relation between abdominal adiposity and elevated BP among adolescent males in Jordan. Methods: Nationally representative sample of male adolescents was selected using multi-cluster sampling technique. Study sample included 1035 adolescent males aged 12 to 17 years. Multiple indicators were used to assess adiposity including waist circumference (WC) and total body fat (TF), truncal fat (TrF), and visceral fat (VF). Systolic blood pressure was measured to assess hypertension. Results: After adjusting for age, smoking status, and physical activity, the odds of having stage two hypertension increased 6, 7, and 8 times for adolescents who were on 90th percentile or above for Trf, VF, and WC, respectively. Conclusion: Elevated BP was significantly associated with total and abdominal adiposity among adolescent males in Jordan. Use of multiple clinical assessment tools is essential to assess abdominal obesity among adolescents.

Knowledge and attitudes regarding Covid-19 among syrian refugee women in Jordan

OBJECTIVES

To explore knowledge and attitude about Covid-19, among Syrian refugee mothers in the Governorate of Irbid, where the first outbreak of Covid-19 in Jordan took place.

METHODS

This is a cross-section study among Syrian refugee mothers, who were pregnant or having had children. Data was collected through an online questionnaire. The survey link was distributed in April 2020, through the social network's messaging services Facebook and WhatsApp. Contact information was obtained from local community centres and non-governmental organisations in the town of Irbid, the north of Jordan.

RESULTS

In total, 389 Syrian refugee mothers participated in the study. It showed that 66% of mother's access information regarding Covid-19. The main sources of information were Facebook 87%, WhatsApp 69%, television 53%, while 21% indicated that they access professional databases or government websites. In general, Syrian refugee mothers were knowledgeable about Covid-19 transmission and prevention. However, they lacked adequate knowledge about transmission of Covid-19 between the mother and the child, and smoking risks associated with Covid-19.

CONCLUSIONS

There are gaps in the knowledge and attitude of Syrian refugee mothers in the Governorate of Irbid in relation to the Covid-19 pandemic. There is a need for further health education measures.

Cognitive functioning in Deaf children using Cochlear implants

Background

Cognitive abilities like language, memory, reasoning, visualization, and perceptual functioning shape human action and are considered critical to the successful interaction with the environment. Alternatively, hearing loss can disrupt a child’s ability to communicate, and negatively impact cognitive development. Cochlear implants (CI) restore auditory input thereby supporting communication and may enhance cognitive performance. This study compares general cognitive development after cochlear implantation (2017–2019) in two groups of Jordanian children implanted earlier (age:4–6 years, N = 22) and later (7–9 years, N = 16) to the development of randomly selected normal hearing peers (N = 48).

Design

Visualization, reasoning, memory, and attention were assessed using the Leiter-R scale at baseline (before implantation), 8 months and 16 months post implantation for children with hearing loss. Same times of testing (baseline, 8 months and 16 months) were used for normal hearing peers.

Results

Over the 16-month period, the cognitive improvement of 4–6-year-old deaf children was greater than that of their normal hearing peers on the scales of visualization (5.62 vs. 4.40), reasoning (2.53 vs. 2.38) and memory (17.19 vs. 11.67). while the improvement of 7–9-year-old was less major than that of their normal hearing peers on all scales.

Conclusions

These results suggest that CI not only enhances communication skills but may improve cognitive functioning in deaf children. However, the extent of this improvement was dependent on age at intervention; current results demonstrated that the children received CI at young ages had better cognitive improvements.

Morphology of the lips, cheeks, and the hard palate of the Egyptian water buffalo (Bubalus bubalis): a focus on histological, histochemical, and ultrastructural aspects

BACKGROUND

The available data is scanty about Egyptian water buffalo lips, cheeks, and palate.

AIMS

The current investigation was focused on describing the morphology of the lip, cheek, and palate.

METHODS

Our study included the gross, light, and electron microscopic examinations of ten heads of the Egyptian water buffalos.

RESULTS

The nasolabial plate surface carried numerous scales of keratinized epithelium. Internal labial surface and labial mucocutaneous junctions were covered with stratified squamous keratinized epithelium. Two types of hair follicles in the dermis included ordinary and cavernous types characterized by cavernous space. The conical papillae on the internal aspect of the oral commissure were projected from the mucous membrane. Seromucous glands were occasionally observed under the oral mucous membrane of the commissure and gave positive PAS and AB. Conical papillae density on the inner cheek surface had some variations: the rostral part had large papillae, while the dorsal part had numerous papillae than the ventral part, the caudal part had a smaller number of papillae, while the middle part was devoid of papillae. Parotid duct opening in the buccal vestibule was without papillae. Conical papillae had two surfaces; the rostral surface was highly keratinized than the caudal one. The buccal gland was a compound tubuloacinar mixed (mucoserous) gland and mucus acini only reacted to PAS and AB. The oral surface of palatine rugae was covered with highly keratinized epithelium than the aboral surface. Palatine glands showed PAS and AB positive.

CONCLUSION

The result describes the relationship between the available food particles, environmental conditions and the lip, cheek, and palate appearance, and structure.

Oral Sucrose for Neonatal Pain: Perception of Jordanian Nurses

BACKGROUND

Neonatal pain management using sucrose has been an established practice in Western countries. However, in the developing world, the practice is still not widely accepted. Neonatal nurses' perceptions about the neonatal pain experience and efficacy of oral sucrose may influence that decision.

PURPOSE

To investigate Jordanian neonatal nurses' perceptions about the use of oral sucrose for neonatal pain.

DESIGN AND SAMPLE

A cross-sectional descriptive design was used to collect data from 191 neonatal nurses working in 3 different hospital settings in northern and middle central Jordan.

MAIN OUTCOME VARIABLES

Knowledge and perception of Jordanian nurses about neonatal pain and oral sucrose and their relationship to demographic variables.

RESULTS

More than half of nurses had knowledge deficit about pain management. Fifty-five percent of the nurses had a positive perception toward pain assessment tools, and the majority indicated positive opinion toward oral sucrose usage. Demographic factors can impact their perceptions.

Knowledge and attitudes toward infant BLS among babysitters and nursemaids working in rural northwest Jordan

Objectives: This study aimed to assess the knowledge and attitude of babysitters and nursemaids toward providing basic life support (BLS) to infants. Setting: This study was conducted at registered nurseries and daycare centers in rural northern Jordan. Participants: The study involved a convenience sample of 77 child caretakers who were looking after infants. Results: Findings showed that majority of participants were unaware of skills needed to manage foreign body aspiration or administer cardiopulmonary resuscitation on infants. More than two-thirds of the participants had never attended any training or educational session on managing foreign body aspiration among infants. Conclusions: The findings indicated that caregivers in kindergartens and nurseries in rural areas in Jordan lacked awareness of safe infant care. Basic resuscitation skills for urgent cases were insufficient, which could increase the risk of sudden and unexpected child death. Thus, this study strongly recommends training, such as a course on infant life support, for babysitters and care center staff.

Caregivers Help-Seeking Behaviors for Postdischarged Neonates from Neonatal Intensive Care Units: A Jordanian Study

PURPOSE

This study will explore and describe help-seeking behaviors and decision-making processes of Arab Muslim caregivers in Jordan when seeking help for their sick neonates after discharge from Neonatal Intensive Care Units (NICU). This study which will contribute to the global discussion on the reasons/conditions contributing to neonatal mortality.

DESIGN AND METHODS

A descriptive cross-sectional survey was used. Two research assistants interviewed 275 identified neonate caregivers by telephone from May 1 to August 30, 2019. Data were analyzed using SPSS version 25.

RESULTS

Caregivers who had a neonate who had been discharged from a NICU were surveyed about the types of condition for which they would seek medical help. The vast majority (98.2%) stated that they would seek help if their child was unconscious and 95.3% reported that they would do so if their child experienced a convulsion. Fewer caregivers (43.3%) stated that abdominal distension (43.3%) would cause them to seek help immediately.

CONCLUSION

Recognition of danger signs during the neonatal period was considered poor among neonate caregivers. Using self-management treatments and home remedies delayed appropriate medical treatment for neonate illnesses. Lack of money was identified as the most common reason for delaying going to or not using health facilities. This study highlights the need to create a specialized program to focus on interventions that could reduce neonatal deaths and improve families' help-seeking behaviors in Jordan.

IMPLICATIONS FOR PRACTICE

Nurses are required to be well-trained to support caregivers to prioritize neonatal issues (pre and post discharge) that require quick action (minutes versus hours) and which most commonly lead to mortality. Nurses are required to provide appropriate education for caregivers pre-discharge and such teachings could be reinforced during home visits.

Testing the Effectiveness of Cognitive Behavioral Therapy in Relieving Nurses' Ageism Toward Older Adults: A Randomized Controlled Trial

Background

Although cognitive-behavioral therapy (CBT) techniques are well known for targeting psychological distresses, to date, no study has investigated their effectiveness in relieving death anxiety and ageism among nurses.

Methods

A parallel randomized controlled trial was conducted according to the CONSORT guidelines during October 2019 at the university hospital. A total of 110 nurses were selected through proportional stratified sampling and randomly assigned to the experimental and control groups. The intervention consisted of six two-hour training sessions delivered over five modules with the integration of different CBT exercises. The effect of CBT was assessed by measuring the differences in the students’ responses to a series of validated questionnaires of study variables pre-test (before the training sessions) and post-test (after the training sessions). Clinical registration was completed at ClinicalTrial.gov (ID: NCT04319393).

Results

Overall, using CBT techniques led to significant improvements in the study outcomes. At postintervention, the nurses who had received CBT training had significantly better self-esteem and interpersonal relationships, a greater sense of symbolic immortality, and less death anxiety and ageism than the nurses in the control group.

Conclusions

CBT is an effective evidence-based psychological intervention for relieving nurses’ ageism towards older adults. The psychological well-being of nurses caring for older adults is crucial, and new techniques should be adopted to relieve nurses’ accumulated stress and decrease their death anxiety. Future studies which investigate the effectiveness of CBT on other forms of discrimination, such as racism and sexism in healthcare settings, are recommended.

Efficacy of Sucrose in Reducing Pain during Immunization among 10- to 18-Month-Old Infants and Young Children: A Randomized Controlled Trial

PURPOSE

Sucrose is recommended to reduce pain associated with vaccination in neonates. However, research results concerning its effectiveness in infants and young children are inconclusive. This study aims to determine the efficacy of sucrose administration in reducing pain during immunization in 10- to 18-month-old infants and young children as assessed by behavioral pain parameters, crying time, and saliva substance (P) concentration.

DESIGN AND METHODS

This was a double-blind, randomized controlled trial and included healthy infants and young children undergoing their 10- to 18-month immunization. Behavioral pain outcome was measured during, and shortly after the last injection. The infant's pain was also measured by a salivary test using substance (P), and videotaping of crying time.

RESULTS

The study results indicate that, compared with a placebo group, the sucrose group had significantly less pain post-immunization (F (1,129) = 1.72, p = 0.001). Moreover, substance (P) was lower in the intervention group post-immunization, and it could be considered a good predictor of pain reduction associated with immunization.

CONCLUSIONS

Sucrose administration during immunization injection helps in reducing pain, which is one of the most critical factors affecting compliance with the immunization schedule. Substance (P) measurement can be used as a predictor of immunization pain level in 10- to 18-month-old infants and young children.

PRACTICE IMPLICATIONS

Sucrose is an effective method to reduce needle pain during immunization; therefore, healthcare providers should administer sucrose as a pain relief intervention in the immunization clinical setting.

Effects of estrogen on Survival and Neuronal Differentiation of adult human olfactory bulb neural stem Cells Transplanted into Spinal Cord Injured Rats.. [DOI: 10.1101/571950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

In the present study we developed an excitotoxic spinal cord injury (SCI) model using kainic acid (KA) to evaluate of the therapeutic potential of human olfactory bulb neural stem cells (h-OBNSCs) for spinal cord injury (SCI). In a previous study, we assessed the therapeutic potential of these cells for SCI; all transplanted animals showed successful engraftment. These cells differentiated predominantly as astrocytes, not motor neurons, so no improvement in motor functions was detected. In the current study we used estrogen as neuroprotective therapy before transplantation of OBNSCs to preserve some of endogenous neurons and enhance the differentiation of these cells towards neurons. The present work demonstrated that the h-GFP-OBNSCs were able to survive for more than eight weeks after sub-acute transplantation into injured spinal cord. Stereological quantification of OBNSCs showed approximately a 2.38-fold increase in the initial cell population transplanted. 40.91% of OBNSCs showed differentiation along the neuronal lineages, which was the predominant fate of these cells. 36.36% of the cells differentiated into mature astrocytes; meanwhile 22.73% of the cells differentiated into oligodendrocytes. Improvement in motor functions was also detected after cell transplantation.

Low birth weight in Jordan: a hospital-based study

Background: Low birth weight (LBW) is one of the leading causes of neonatal and infant morbidity and mortality.Objective: To determine the prevalence and possible risk factors associated with LBW in four regional hospitals in Jordan.Methods: This retrospective study analyzed the medical records of all singleton live births for the period 2011-2015.Results: A total of 22,789 singleton live births were included for this study. Of these, 4133 (18%) had a LBW. Rates of LBW increased over the 5 years study period. Factors associated with LBW were preterm birth, pregnancy complications or comorbidities, older maternal age (≥35 years), first-born infants, and having a female baby.Conclusion: Midwives' assessment and health education messages to mothers included awareness of risk factors associated with LBW of neonates in Jordan. Effective public health interventions need to highlight the importance of a healthy diet and valuing female off-spring.

Factors Associated With Infant Pain Severity Undergoing Immunization Injections

PURPOSE

Factors influencing infants' behavioral and vocal (cry) response to painful stimuli are explored to improve pain management plans for infants undergoing immunizations.

DESIGN AND METHODS

An observational study design was used. Pain responses of 60 to 75 days-old infants (44% male vs 56% female) undergoing two-month immunization injections were videotaped and coded using the Modified Behavioral Pain Scale (MBPS), and duration of total crying time during injection was recorded. The influences of five factors (gender, caregiver attendance, previous experience of nociception (circumcision), mode of delivery), and weight (birth and current) were examined at baseline, during and post-immunization.

RESULTS

Higher birth weight was the most significant factor that reduced pain responses during (p = 0.001) and post-immunization (p = 0.03). A higher birth weight reduced full lung crying (p = 0.04), which reflects crying during injection as compared to total crying time. Vaginal delivery had a significant effect on behavioral pain responses of infants only post-immunization (p = 0.006). Parent's presence in the immunization room significantly reduced total crying time (p = 0.03). Uncircumcised male infants had a significant reduction in behavioral pain responses during immunization (p = 0.01) compared to circumcised infants.

CONCLUSIONS

The literature well supports the acknowledgement of early pain experience and its psychological consequences. Knowing and controlling for each of mentioned factors early in life during every painful procedure could improve coping mechanisms of infants for any painful procedures later in life.

PRACTICE IMPLICATIONS

Control of certain factors during early life experiences can modify pain of immunization.

Number and Frequency of Routinely Applied Painful Procedures in University Neonatal Intensive Care Unit

Neonates at the neonatal intensive care unit (NICU) are at high risk for procedural pain exposure. This study describes the type and frequency of procedures in neonates admitted to University Intensive Care Unit. This was a prospective cohort study of 150 neonates admitted to the NICU during the first 7 days of life at a governmental hospital. The type and frequency of procedures were evaluated using a tool which included the type and number of procedures performed per shift. A total of 14,008 painful procedures were performed on neonates with an average of 97.11 painful procedures per baby and 13.9/day for each baby. Adhesive removal (21.3%) was the most frequently performed procedure. The number of painful procedures was inversely correlated with gestation age ( p < .001) and birth weight ( p < .001). The number of painful procedures performed on neonates is high, particularly for neonates with small gestational age and low birth weight babies.

Sudden unexpected infant death in Jordan and the home environment

BACKGROUND

The aim of this study was to evaluate maternal common practice for infant sleep care and the home environment, in order to explore the major risk factors associated with sudden unexpected infant death in Jordan.

METHODS

Data were collected via semi-structured questionnaire interview to investigate the sociodemographic features, infant sleep practices and home environments. The sample included 604 mothers with infants <1 year old. Descriptive statistics were generated.

RESULTS

Sleep practices were identified as leading factors in unexpected infant death. They included infant head covering (84%), heavy bedding with multiple quilts (81%) or blankets (67%), and co-bedding (66%). Environmental risk factors included high incidence of smoking, exposure to toxic solid fuel heaters during winter and inadequate room ventilation.

CONCLUSION

Factors leading to unexpected infant death were high in Jordan. Unsafe infant sleeping practices and poor environmental factors put infants at high risk of sudden death. Lack of awareness of risk factors increases the risk.

Prevalence of Hypovitaminosis D Among Jordanian Healthy Infants: A Descriptive Cross Sectional Study

To determine vitamin D deficiency and associated risk factors of hypovitaminosis D among Jordanian healthy infants.

DESIGN AND METHODS

A total of 171 infants receiving a routine health check at a Maternal and Child Health Care Center were recruited. Plasma vitamin D 25-OHD level was assessed using a standard analysis of a blood sample. Other data collected included age, gender, birth order, season of birth, and mode of feeding.

RESULTS

Prevalence of vitamin D deficiency (≤15 ng/mL) was 77% (132 out of 171 infants). Infants at risk of vitamin D deficiency were those between 1 to 6 months of age, male, third born or later, born in winter, and exclusively breastfed. The multivariate model showed birth order to be the largest contributor of vitamin D deficiency (R(2)=0.196), followed by breastfed infants (R(2)=0.071), infants born in winter (R(2)=0.037), male gender (R(2)=0.028), and infants aged between 1 and 6 months (R(2)=0.027).

CONCLUSION

Hypovitaminosis D appears to be more common among healthy infants in Jordan. Hypovitaminosis D was found to be common among third or later exclusively breastfeed male infants aged 1 to 6 months who were born during winter.

PRACTICE IMPLICATION

Maternal and child health nurses have a critical role to play in educating mothers about the importance of preventing hypovitaminosis D through adequate sun exposure and ensuring adequate supplementation. A higher dose of vitamin D supplementation for high-risk infants beyond the age of 1 year from developing countries should be administered.

Midwives’ Experiences, Education, and Support Needs Regarding Basic Newborn Resuscitation in Jordan

Newborns who are compromised at birth require rapid attention to stabilize their respiration attempts. Lack of knowledge regarding basic newborn resuscitation is a contributing factor to poor newborn health outcomes and increased mortality. The purpose of this study was to explore Jordanian midwives’ experiences, education, and support needs to competently perform basic newborn resuscitation. Qualitative descriptive methodology was used to analyze a convenience sample of 20 midwives. A thematic approach was used to analyze the data. Participants discussed their experiences of basic newborn resuscitation including knowledge, skills, and barriers and suggested solutions to improve practice. Four themes were revealed: lack of knowledge and skills in newborn resuscitation, organizational constraints, inadequate teamwork, and educational needs. The midwives perceived that their ability to perform newborn resuscitation was hindered by lack of knowledge and skills in newborn resuscitation, organizational constraints (such as lack of equipment), and poor co-ordination and communication among team members.

Diuretics for transient tachypnoea of the newborn

BACKGROUND

Transient tachypnoea of the newborn (TTN) results from delayed clearance of lung liquid and is a common cause of admission of full-term infants to neonatal intensive care units. The condition is particularly common after elective caesarean section. Conventional treatment involves appropriate oxygen administration and continuous positive airway pressure in some cases. Most infants receive antibiotic therapy. Hastening the clearance of lung liquid may shorten the duration of the symptoms and reduce complications.

OBJECTIVES

To determine whether diuretic administration reduces the duration of oxygen therapy and respiratory symptoms and shortens hospital stay in term infants presenting with transient tachypnoea of the newborn.

SEARCH METHODS

An updated search was carried out in September 2015 of the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library issue 9, 2015), MEDLINE via Ovid, EMBASE, PubMed, and CINAHL via OVID.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that compared the effect of diuretics administration versus placebo or no treatment in infants of less than seven days of age, born at 37 or more weeks of gestation with the clinical picture of transient tachypnoea of the newborn.

DATA COLLECTION AND ANALYSIS

We extracted and analysed data according to the methods outlined in the latest Cochrane Handbook for Systematic Reviews of Interventions. Two review authors assessed trial quality in each potentially eligible manuscript and two review authors extracted data.

MAIN RESULTS

Our previous systematic review included two trials enrolling a total of 100 infants with transient tachypnoea of the newborn (Wiswell 1985; Karabayir 2006). The updated search revealed no new trials. Wiswell 1985 randomised 50 infants to receive either oral furosemide (2 mg/kg body weight at time of diagnosis followed by a 1 mg/kg dose 12 hours later if the tachypnoea persisted) or placebo. Karabayir 2006 randomised 50 infants to receive either intravenous furosemide (2 mg/kg body weight) or an equal volume of normal saline placebo. Neither trial reported on the need for respiratory support. Neither trial demonstrated a statistically significant impact of furosemide on transient tachypnoea of the newborn regarding duration of symptoms or length of hospitalisation.

AUTHORS' CONCLUSIONS

Diuretics cannot be recommended as treatment for transient tachypnoea of the newborn and it should not be used unless additional data become available. This finding suggests that either furosemide is not effective in promoting resorption of lung fluid, or factors other than delayed resorption of this fluid contribute to the pathogenesis of transient tachypnoea of the newborn. The question remains as to whether furosemide given to the infant (or even to the mother before caesarean section) might shorten the duration of the illness. As elective caesarean section continues at a high level, these two interventions might be worthy of trials.

Factors associated with birth weight inequalities in Jordan

BACKGROUND

Birth weight is a good indicator of mothers' and neonates' nutritional status, and it contributes to the newborn baby's survival, health, growth and development.

AIM

This study identified social factors associated with differences in the mean birth weight of newborn babies in Jordan.

METHODS

This retrospective study analysed medical records to determine possible risk factors associated with differences in newborn BW in the Irbid governorate of Jordan. All full-term singleton births during the year 2010 were reviewed. Abstracted data included mother's age, educational level, and monthly family income. Newborn information included birth weight, gender and birth order.

RESULTS

A total of 5414 full-term singleton births were included. Of these, 15.1% were low birth weight, 73.6% were normal birth weight, and 11.3% were high birth weight. Bivariate analysis of variance revealed that low mean birth weight was associated with female gender, first-born babies, higher maternal age (>35 years), lower educational level and lower income (<500 JD). Multivariate analysis of variance revealed that mean birth weight was lower in female infants, first-born infants, infants of less educated mothers, higher age and low monthly income.

LIMITATIONS

The findings can be generalized to full-term singleton pregnancies in countries who share similar cultural and traditional values.

CONCLUSION

Education of mothers is a modifiable variable that can positively influence birth weight, particularly in the case of female and first-born infants.

IMPLICATION FOR NURSING AND HEALTH POLICY

The findings inform our understanding of some social factors affecting birth weights of neonates in Jordan and development of effective public health interventions that could reduce the adverse effects of such factors on newborn birth weight. Preconception and antenatal care is also important for early detection of such possible risk and targeting mothers who require early interventions and support.

Furosemide for transient tachypnoea of the newborn

BACKGROUND

Transient tachypnoea of the newborn (TTN) results from delayed clearance of lung liquid and is a common cause of admission of full term infants to neonatal intensive care units.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that compared the effect of furosemide administration versus placebo or no treatment in infants of less than seven days of age, born at 37 or more weeks of gestation with the clinical picture of transient tachypnoea of the newborn.

DATA COLLECTION AND ANALYSIS

We extracted and analysed data according to the methods outlined in the latest Cochrane Handbook for Systematic Reviews of Interventions. Two review authors assessed trial quality in each potentially eligible manuscript and two review authors extracted data.

MAIN RESULTS

Our updated review includes two completed trials. Wiswell 1985 and Karabayir 2006 investigated 100 infants with transient tachypnoea of the newborn. Wiswell 1985 randomised 50 infants to receive either oral furosemide (2 mg/kg body weight at time of diagnosis followed by a 1 mg/kg dose 12 hours later if the tachypnoea persisted) or placebo.

Sweet-tasting solutions for needle-related procedural pain in infants one month to one year of age

BACKGROUND

Administration of oral sucrose or glucose with and without non-nutritive sucking is frequently used as a non-pharmacological intervention for needle-related procedural pain relief in infants.

OBJECTIVES

To determine the effectiveness of sweet-tasting solutions for needle-related procedural pain in infants one month to one year of age compared with no treatment, placebo, other sweet-tasting solutions, or pharmacological or other non-pharmacological pain-relieving methods.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012); MEDLINE via Ovid (1966 to 2012); CINAHL via OVID (1982 to 2012). The World Health Organization International Clinical Trials Registry Platform was also searched for any ongoing trials. Clinical trial registries, conference proceedings and references for randomised controlled trials (RCTs) were also searched. An updated search was run to capture any new publications before finalising the review in April 2012 and no new included studies were identified. Two review authors (MK & JF) independently abstracted data and assessed quality using a standard form. Authors have been contacted for missing data.

SELECTION CRITERIA

Randomised-controlled trials using a sweet-tasting solution to treat pain in healthy term infants (gestational age 37 weeks and over), between one month and 12 months of age who required needle-related procedures. These procedures included but were not limited to: subcutaneous or intramuscular injections, venepuncture, and heel lance. Studies in which the painful procedure was circumcision, lumbar puncture or supra-pubic bladder aspiration were not included as they are more severe and painful than needle-related procedures. Control conditions included no treatment or placebo (water) or any other identical intervention (same appearance and consistency) without active ingredient, another sweet-tasting solution, a pharmacological pain-relieving method (e.g. paracetamol, topical anaesthetic cream), non-pharmacological pain-relieving method (e.g. distraction method, non-nutritive sucking).

DATA COLLECTION AND ANALYSIS

Assessment of trial quality, data extraction and synthesis of data were performed using standard methods of the Cochrane Pain, Palliative and Supportive Care Group. We report mean differences (MD) with 95% confidence intervals (CI) using fixed-effect models as appropriate for continuous outcome measures. We planned to report risk ratio (RR) and risk difference (RD) for dichotomous outcomes. The Chi(2) test and I(2) statistic were used to assess between-study heterogeneity.

MAIN RESULTS

Sixty-five (65) studies were identified for possible inclusion in this review. Fourteen published RCTs with a total of 1551 participants met the inclusion criteria. Duration of cry was significantly reduced in infants who were administered a sweet-tasting solution [MD -13.47 (95% CI -16.80 to -10.15)], P < 0.00001 compared with water. However, there was considerable heterogeneity between the studies (I(2) = 94%) that we were unable to explain. Meta-analysis was not able to be undertaken for any of the other outcome measures, except for cry duration, because of differences in study design. However, most of the individual studies that measured pain found sucrose to significantly reduce pain compared with the control group. One study compared sucrose and Lidocaine-prilocaine cream and no significant difference was found between the two treatments for the outcomes pain and cry duration. Due to the differences between the studies, we were unable to identify the optimal concentration, volume or method of administration of sweet-tasting solutions in infants aged one to 12 months. Further large RCTs are needed.

AUTHORS' CONCLUSIONS

There is insufficient evidence to confidently judge the effectiveness of sweet-tasting solutions in reducing needle-related pain in infants (one month to 12 months of age). The treatments do, however, appear promising. Data from a series of individual trials are promising, as are the results from a subset meta-analysis of studies measuring duration of crying. Further well controlled RCTs are warranted in this population to determine the optimal concentration, volume, method of administration, and possible adverse effects.

Localization of the epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR) in the bovine testis

In the last few decades, several growth factors were identified in the testis of various mammalian species. Growth factors are shown to promote cell proliferation, regulate tissue differentiation, and modulate organogenesis. In the present investigation we have studied the localization of EGF and EGFR in the adult bovine testis by means of immunohistochemical method. Our results demonstrated that EGF and EGFR were localized solely to the bovine testicular germ cells (spermatogonia, spermatocytes, and round spermatids). In contrast, the somatic testicular cells (i.e., Sertoli, Leydig, and myofibroblast cells) exhibited no staining affinity. EGF and EGFR were additionally detected in the epithelial lining of straight tubules and rete testis. Interestingly, the distribution of EGF and EGFR in the germ cells was mainly dependent upon the cycle of the seminiferous epithelium since their localization appeared to be preponderant during the spermatogonia proliferation and during the meiotic and spermiogenic processes. In conclusion, such findings may suggest that EGF and EGFR are important paracrine and/or autocrine regulators of spermatogenesis in bovine.

The Therapeutic Potential of Statins in Neurological Disorders

Statins are currently among the most commonly prescribed agents for the prevention of cardiovascular disease. Statins reduce serum cholesterol levels by reversibly inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase, the rate-limiting enzyme in cholesterol biosynthesis, in the nanomolar range. Mounting evidence suggests that in addition to their vascular effects such as stabilization of atherosclerotic plaques and decreased carotid intimal-medial thickness, statins have additional properties such as endothelial protection via actions on the nitric oxide synthase system as well as antioxidant, anti-inflammatory and anti-platelet effects. These effects of statins might have potential therapeutic implications in various neurological disorders such as stroke, Alzheimer's disease, Parkinson's disease, multiple sclerosis and primary brain tumors. In this review, the major protective mechanisms of statins and their applicability to the treatment of neurological disease are summarized. Although further experiments are required, currently available data would seem to indicate that clinical trials to determine the safety and efficacy of statins in a number of disorders are warranted.

[Sequelae of intra-articular calcaneal fractures: patterns and management]

PURPOSE OF THE STUDY

We reviewed retrospectively 24 feet with sequelae of transtalar process fractures of the calcaneum in order to identify the lesion pattern and determine optimal management options, both for acute and sequelar lesions.

MATERIAL AND METHODS

There were fourteen men and nine women, mean age 42 years (19-73). Twenty-three had subtalar osteoarthritis, eight had calcaneocuboid osteoarthritis, and fifteen had lateral submalleolar conflicts. There were twelve fibular tendon dislocations or fissurations, three tarsal tunnel syndromes, and two plantar splinters. Prior to treatment, all patients complained of pain. Preoperatively, walking distance was less than 500 m for thirteen patients, 2000-3000 m for four, and greater than 3000 m for five. Mean subtalar joint motion was 30% (0-100%) compared with the healthy side and mean frontal misalignment of the rear foot was 6 degrees valgus. Physical examination, podoscopy and x-rays were obtained in all patients. The Kitaoka score was noted.

RESULT

Mean follow-up was 36 months (24-72). Sequelae were treated with a single procedure or with combinations: subtalar arthrodesis (n = 23) including one in association with calcaneocuboid arthrodesis, tension on fibular tendons (n = 7), neurolysis of the posterior tibial nerve (n = 3), resection of plantar splinters (n = 2), resection of the lateral shell (n = 14), and osteotomy (n = 2) to lower the greater tubercle of the calcaneum because of pain when wearing shoes. The mean Kitaoka function score was 31.7/100 (14-79) preoperatively. After treatment, the mean score was 81.7/100 (31-94), giving a 73.2% gain. The outcome was considered good in sixteen feet, fair in six, and poor in two. Mean walking distance was greater than 3000 m for 18 patients. Mean frontal misalignment of the rear foot under loading was 4.5 degrees valgus and the podoscopy demonstrated flat foot in thirteen patients. Three subtalar arthrodesis required revision for nonhealing.

DISCUSSION

Initial treatment of a fracture, particularly an articular fracture, of the calcaneum must avoid disabling postoperative pain and shoe wearing problems. These sequelae basically concern: subtalar and calcaneocuboid arthritis, lateral submalleolar conflict, fibular tendon injury, plantar splinters, tarsal tunnel syndrome, loss of height, and misalignment of the rear foot. At the sequelar stage, the physical examination is primordial to confirm the lesion and search for any complication which could develop later postoperatively when walking distance becomes longer. For nine patients with residual pain, four resulted from lesions which were missed at the preoperative physical examination. Arthrodesis of the subtalar joint should be preferred over realignment of the rear foot and can be associated with the treatment of conflicts. This management scheme allows treating during a single operative time all sequelae, thus limiting recovery time. A scan of the ankle and foot with or without opacification of the fibular tendons is needed to confirm the physical examination which, for us, remains the key to successful surgery.

[Twenty nine shoulder reconstructions after resection of the proximal humerus for neoplasm with mean 7-year follow-up]

PURPOSE OF THE STUDY

Techniques available for shoulder reconstruction after resection of a tumor of the proximal humerus include scapulohumeral arthrodesis, humerus prosthesis with or without an allograft, inverted prostheses, and massive allografts. The purpose of this study was to review clinical and radiological outcomes in a series of 29 patients (20 men and 9 women) who underwent resection-reconstruction of the proximal humerus and to establish from these cases a decision making algorithm for therapeutic indications as a function of tumor invasion.

MATERIAL AND METHODS

The tumors were 20 chondrosarcomas, five osteosarcomas, two Ewing sarcomas and one malignant hemangiopericytoma. In 17 patients epiphyso-metaphyseal or epiphyso-metaphyso-diaphyseal resection was performed with preservation of the abductor muscles (type S34A or S345A according to the Musculoskeletal Tumor Society classification). For 12 patients epiphyso-metaphyseal or epiphyso-metaphyso-diaphyseal resection was performed without preservation of the abductor muscles (type S34B or S345B). Reconstruction was achieved using a centromedullary cemented nail in one patient, scapulohumeral arthrodesis in three, a massive humerus prosthesis in 15, and composite humerus prosthesis in three and an inverted prosthesis in seven. The functional score of the Musculoskeletal Tumor Society (MSTS) and standard x-rays were used to assess outcome.

RESULTS

Mean follow-up was 85 months (range 16-300). The mean MSTS score was 88% for inverted prostheses, 76% for composite prostheses, 72.6% for massive prostheses, 75% for scapulohumeral arthrodeses, 67% for massive prostheses, and 80% for cemented centromendullary nail. Five patients died from their malignant disease and one from another cause. Four patients are alive but with active disease after a mean follow-up of 108 months and 19 patients (65.5%) are alive and free of locoregional recurrence or metastasis after a mean 83.5 months. We had 28 complications. Glenohumeral instability was the most frequent (11 cases).

DISCUSSION

Resection of the upper portion of the humerus should be performed to achieve cancerologically satisfactory tumor resection and enable shoulder resection, if possible, with preservation of a viable and functional abductor system. The functional outcome after such reconstruction depends on the type of bony resection, but also on the sacrifice of the rotator cuff and the deltoid muscle. In light of our experience and results in the literature, we advocate, despite the small number of cases for the different reconstructions, the following decision-making algorithm after resection of the proximal humerus without joint invasion: when the resection removes the rotator cuff and the deltoid (or the axillary nerve), there are two options: scapulohumeral arthrodesis or massive humerus prosthesis for patients who do not desire a complex therapy with a long postoperative period; when the resection preserves the rotator cuff and/or the deltoid muscle, reconstruction can be achieved with a composite (inverted or not) prosthesis with suture of the cuff tendons. We prefer the inverted composite prosthesis; if the deltoid muscle can be preserved but not the rotator cuff, the composite inverted prosthesis appears to be the most logical solution, but scapulohumeral arthrodesis can be proposed in selected cases.

Ipsilateral fibular transposition in tibial nonunion using Huntington procedure: a 12-year follow-up study

Eleven patients (10 men and 1 woman) with a mean age of 32 years (range: 16-61 years) and a mean follow-up of 12 years (range: 2-21 years) were studied retrospectively after ipsilateral fibular transposition. The cause of tibial nonunion was a motor vehicle collision (MVC) in eight patients, a fall from a window in one, an adamantinoma in one, and osteomyelitis in one. There was one type I and eight type IIIb open fractures according to the Gustilo classification, and the nonunion was infected in seven patients. Healing of the tibial defect was obtained in eight patients, after a mean interval of 10.5 months. In the patient with the adamantinoma, resection of the tumour left a 22 cm defect in the tibia. Two patients required amputation for acute local infection. Seven of the eight patients in whom tibial union was achieved were able to walk with no aids. The authors conclude that transposition of the ipsilateral fibula is a valuable component of the therapeutic armamentarium and a salvage procedure for patients with multi-operated, infected or uninfected, tibial nonunion.

Aneurysm of the coeliac artery

A case of coeliac artery aneurysm associated with multiple splanchnic artery aneurysms is reported. This abnormality involved the gastroepiploic and hepatic arteries. The coeliac artery was ligated at laparotomy and the liver revascularized by direct anastomosis of the common hepatic artery to the aorta. Arteriography on the fifth postoperative day showed a satisfactory result. The surgical problems associated with aneurysms of the coeliac artery are reviewed.

[Postoperative vascular infections. A pathognomonic x-ray computed tomographic sign]

The potential gravity of post-operative vascular infection makes early diagnosis essential. We report a case where this diagnosis was made on CT findings alone, in the absence of any other signs of infection. Rapid intervention led to complete cure. Beyond the immediate post-operative period, the presence of gas on the CT scan is rare but pathognomonic in the absence of a cutaneous fistula. The presence of this sign is therefore sufficient to indicate that reintervention is mandatory.
