The transition from fetus to neonate – an endocrine perspective

Gluckman PD, Sizonenko SV, Bassett NS. The transition from fetus to neonate - an endocrine perspective. Acta Pædiatr 1999; Suppl 428: 7–11. Stockholm. ISSN 0803–5326
The transition from fetus to neonate involves three phases: late gestation, parturition and the processes needed to establish independent homoeostatic regulation after separation from the placenta. These phases are regulated by a series of fetal and placental endocrine events. Glucocorticoids have an important role in the preparation for birth, including involvement in lung and cardiac development, and the maturation of enzymes in a variety of pathways. Fetal Cortisol production is, in turn, also under hormonal control. Parturition is a complex process, which is still poorly understood in humans. The final steps are largely dependent on the effect of prostaglandin F_2α on the myometrium associated with increased oxytocin activity. The transition to birth is accompanied by changes in respiration, circulation, glucose homoeostasis, and the onset of independent oral feeding and thermoregulation. Several examples of endocrine components of the transition from fetal to neonatal life are reviewed here: the role of prostanoids, the onset of thermogenesis, and changes in the thyroid hormone and growth hormone axes. The effects of hormone levels on prematurity and growth retardation are also discussed. □ Birth transition, fetus, gestation, hormonal control, neonate, parturition

Army Hospital (R & R) has acquired an Electrohydraulic Lithotripter (DIREX NOVA), the first of its kind in the Armed Forces for the treatment of stone diseases. The first 200 patients who underwent Extracorporeal Shock Wave Lithotripsy (ESWL) have been analysed in this study. This being a pilot study would serve as a beginning of an ongoing experience with this non-invasive procedure and its benefits for the stone population in the Armed Forces.KEY WORDS: ESWL, Lithotripsy     

Fluid Balance,Diuretic Use,and Mortality in Acute Kidney Injury

Summary

Background and objectives

Management of volume status in patients with acute kidney injury (AKI) is complex, and the role of diuretics is controversial. The primary objective was to elucidate the association between fluid balance, diuretic use, and short-term mortality after AKI in critically ill patients.

Design, setting, participants, & measurements

Using data from the Fluid and Catheter Treatment Trial (FACTT), a multicenter, randomized controlled trial evaluating a conservative versus liberal fluid-management strategy in 1000 patients with acute lung injury (ALI), we evaluated the association of post-renal injury fluid balance and diuretic use with 60-day mortality in patients who developed AKI, as defined by the AKI Network criteria.

Results

306 patients developed AKI in the first 2 study days and were included in our analysis. There were 137 in the fluid-liberal arm and 169 in the fluid-conservative arm (P = 0.04). Baseline characteristics were similar between groups. Post-AKI fluid balance was significantly associated with mortality in both crude and adjusted analysis. Higher post-AKI furosemide doses had a protective effect on mortality but no significant effect after adjustment for post-AKI fluid balance. There was no threshold dose of furosemide above which mortality increased.

Conclusions

A positive fluid balance after AKI was strongly associated with mortality. Post-AKI diuretic therapy was associated with 60-day patient survival in FACTT patients with ALI; this effect may be mediated by fluid balance.     

Modalities of Empowerment and Strengthening of Ex-servicemen

Background

Older people including ex-servicemen (ESM) in India are left to fend for themselves due to nuclear family system. Most children are not staying with them due to reasons such as acquiring of education or employment at distant places. These factors, coupled with deteriorating health with advancing age, change in value system and attitude amongst children who give more importance to materialism, it was felt necessary to find modalities to empower and strengthen ESM by available methods of including progressive weight training, yoga and meditation.

Methods

An interventional “Before and After” study was planned for a period of three months for in-patient ESM of a military hospital for common lifestyle diseases namely stroke, diabetes, senile depression, acute myocardial infarction and hypertension. Data of anthropometry, laboratory investigations and Hamilton rating scale for depression (HRSD) were taken before the study. These cases were then subjected to interventions (progressive weight training and spiritual health enhancement by yoga with meditation for three months) followed by same measurements again.

Result

Statistically significant differences were observed before and after study with respect to pulse, respiratory rate, blood pressure, blood glucose, total cholesterol, low density lipoproteins (LDL), very low density lipoproteins (VLDL) and Hamilton depression score (p<0.05). The sleep pattern, sense of well being and posture while sitting to standing and walking with degree of support (stick/other person''s help) improved considerably after the interventions.

Conclusion

ESM are recommended to be trained much before retirement on progressive weight training and yoga in regimental centre/station institute. Provision to be made in existing ex-servicemen contributory health scheme (ECHS) polyclinics for employment of part time trainers for weight training and yoga. The physical and spiritual strengthening results in better capability to deal with old age and its problems.Key Words: Ex-servicemen, Progressive weight training, Yoga, Spiritual health     

Efficacy and Safety of Terbinafine Hydrochloride 1% Cream vs. Sertaconazole Nitrate 2% Cream in Tinea Corporis and Tinea Cruris: A Comparative Therapeutic Trial

Context:

To the best of our knowledge, till date no study comparing the efficacy and safety of terbinafine hydrochloride 1% cream and sertaconazole nitrate 2% cream has been done in localized tinea corporis and tinea cruris.

Aims:

This clinical trial was carried out to study and compare the efficacy of topical terbinafine hydrochloride 1% cream and sertaconazole nitrate 2% cream in localized tinea corporis and tinea cruris and to know the adverse effects of these antifungal creams.

Settings and Design:

In this prospective, single blind, randomized control trial with two arms, patient were randomized into two groups Group A (treatment with terbinafine cream) and Group B (treatment with sertaconazole cream). A total of 38 patients were enrolled for the study, 20 patients in group A and 18 patients in group B. But five patients of group A and three patients of group B were lost for follow-ups. Therefore sample size was of 30 patients with 15 patients in group A and group B each.

Materials and Methods:

Patients in group A and B were treated with twice daily topical 1% terbinafine hydrochloride and 2% sertaconazole nitrate cream respectively for a total duration of three weeks. Clinical improvement in signs and symptoms of each clinical parameter, namely itching, erythema, papules, pustules, vesicles, and scaling were graded weekly and clinical cure was assessed. KOH mount and culture was done weekly up to 3 weeks to access mycological cure. Fungal culture was done on Sabouraud''s dextrose agar with chloramphenicol and cycloheximide.

Statistical Analysis Used:

Statistical analysis was done using students paired and unpaired t-tests from the data obtained.

Results:

Comparison between Group A and Group B for complete cure (clinical and mycological) showed that at the end of 3 weeks both terbinafine and sertaconazole groups had 100% complete cure. When the two groups were compared for complete cure, at the end of 1^st and 2^nd week, statistically non-significant results were observed (P = 0.461 and P = 0.679 respectively). However, at the end of 2^nd week, complete cure rate for terbinafine was 80% as compared to 73.35% for sertaconazole with no statistical significance. In both Group A and Group B, clinically significant local side effects like erythema, swelling, stinging sensation, or increased itching were not noticed. A majority of our patients in both the group showed Trichophyton rubrum followed by Trichophyton mentagrophytes growth on culture. In Group A, 11 patients showed growth of T. rubrum, 2 patients showed growth of T. mentagrophytes, and 1 patient had only KOH test positive. In Group B, 10 patients revealed growth of T. rubrum, followed by growth of T. mentagrophytes in 3 and Microsporum canis in 2 patients. The therapeutic response is more or less same in infection with different species.

Conclusions:

The newer fungistatic drug sertaconazole nitrate 2% cream was as effective as terbinafine hydrochloride 1% cream which is one of the fungicidal drugs, though terbinafine hydrochloride 1% cream has higher rates of complete cure at the end of 2 weeks as compared to sertaconazole nitrate 2% cream. Both the drugs showed good tolerability with no adverse effects.     

Effect of Community-based Behavior Change Communication on Delivery and Newborn Health Care Practices in a Resettlement Colony of Delhi

Background:

Neonatal morbidity and mortality in India continue to be high. Among other reasons, newborn care practices are major contributors for such high rates.

Objective:

To assess the effect of behavior change communication (BCC) package among pregnant women regarding neonatal care.

Materials and Methods:

Semistructured and pretested schedule was used to interview 200 multigravidas on various aspects of neonatal care. Based on the preliminary data, BCC package was designed and implemented in intervention block in the community. Follow-up was done to find out change in their behavior.

Statistical Analysis:

Data were analyzed using Epi info and Fischer exact test and chi-square test were applied in the baseline data. A P value of less than 0.05 was considered significant. Effect of the BCC package is given in terms of relative risk.

Results:

BCC package increased 1.76 times higher number of deliveries conducted by trained dais in intervention group. There was significant improvement in using sterile cord tie (P = 0.01), applied nothing to the cord (P < 0.0001) and giving bath to their baby within 6 h of birth (P = 0.02) in intervention group as compared to nonintervention group. Significant difference was found between the two groups with regard to breastfeeding practices of baby. Harmful practices were reduced in the intervention group. Significant improvement was found in intervention group as compared to nonintervention group with regard to knowledge of danger signals, physiological variants, management of breastfeeding-related problems, and awareness of skin-to-skin technique for the management of hypothermic baby.

Conclusion:

Inadequate knowledge and adverse practices regarding neonatal care among mothers in study areas were found. BCC package had favorable impact on behavior of mothers for neonatal care in intervention group.     

Catheter balloon-related urethral trauma in children

Aim:   To review urethral injuries arising from incorrect balloon inflation in children undergoing urinary catheterisation.
Method:   Retrospective review from 1995–2006. Children who sustained catheter-related injury at The Children's Hospital at Westmead were identified through medical records database and reviewed.
Results:   Six patients were identified over the 11-year period. All six were boys. Age ranged from <1 month to 16 years. All but one occurred in hospital. All injuries were confirmed by urethrogram. Bulbar and prostatic urethra was involved in an equal number of children studied. Three patients required suprapubic catheters. Follow-up imaging revealed healing without stricture in all patients.
Conclusion:   Balloon-related urethral trauma can be avoided by educating health-care professionals on proper placement and confirmation of position of catheter. Though there were no long-term complications noted, a temporary suprapubic diversion may be needed.     

Albuminuria and Estimated Glomerular Filtration Rate Independently Associate with Acute Kidney Injury

Acute kidney injury (AKI) is increasingly common and a significant contributor to excess death in hospitalized patients. CKD is an established risk factor for AKI; however, the independent graded association of urine albumin excretion with AKI is unknown. We analyzed a prospective cohort of 11,200 participants in the Atherosclerosis Risk in Communities (ARIC) study for the association between baseline urine albumin-to-creatinine ratio and estimated GFR (eGFR) with hospitalizations or death with AKI. The incidence of AKI events was 4.0 per 1000 person-years of follow-up. Using participants with urine albumin-to-creatinine ratios <10 mg/g as a reference, the relative hazards of AKI, adjusted for age, gender, race, cardiovascular risk factors, and categories of eGFR were 1.9 (95% CI, 1.4 to 2.6), 2.2 (95% CI, 1.6 to 3.0), and 4.8 (95% CI, 3.2 to 7.2) for urine albumin-to-creatinine ratio groups of 11 to 29 mg/g, 30 to 299 mg/g, and ≥300 mg/g, respectively. Similarly, the overall adjusted relative hazard of AKI increased with decreasing eGFR. Patterns persisted within subgroups of age, race, and gender. In summary, albuminuria and eGFR have strong, independent associations with incident AKI.It has long been recognized that an episode of acute kidney injury (AKI) can have serious health consequences.^1–4 Even a relatively small degree of renal injury increases a patient''s risk of a prolonged hospital stay, chronic kidney disease (CKD), ESRD, and death.^2,5–10 Over the last 2 decades, the incidence of hospitalized AKI has increased dramatically.^11–14 Precise estimations vary depending on population and method of case identification, but a recent community-based study of AKI estimated the incidence of nondialysis requiring AKI at 522 per 100,000 population per year and dialysis-requiring AKI at 30 per 100,000,¹³ which is well over that of ESRD.¹⁴ This increase in the burden of disease, taken with the associated poor long-term outcomes, has established AKI as a major public health issue.¹⁴Beyond routine supportive care, there exists little established medical therapy for AKI.¹⁵ Many current lines of research are focused on the prevention of AKI. However, few prospective, population-based studies have evaluated the development of AKI.^3,13,16 Hsu et al.,^13,17 along with multiple observational series in various clinical settings, have clearly established older age and CKD as risk factors for AKI.^18–24 Other observed associations with AKI include black race and male gender.^11,18,25 Proteinuria, an established risk factor in the development of cardiovascular disease,^26,27 ESRD,²⁸ and death,²⁹ is less studied in its role in the development of AKI. Hsu and colleagues demonstrated the prospective association of proteinuria with dialysis-requiring AKI; however, the proteinuria classification was binary and based on dipstick measurement.¹⁷ To our knowledge, no study has quantified the independent dose response of albuminuria with AKI hospitalization, including less severe AKI. Our study''s objective was thus to characterize prospectively the association between baseline urine albumin-to-creatinine ratio (UACR) and hospitalizations for AKI, controlling for established and potential risk factors such as CKD, age, and cardiovascular comorbidities.
