Authors:Anurag kondum , SS kang , Ajit Bhardwaj, Shivinder Singh
Int J Biol Med Res. 2024; 15(1): 7731-7734
Abstract:
Propofol versus Dexmedetomidine in Reducing Emergence Agitation after Sevoflurane Anaesthesia Original Article Abstract Introduction - Emergence agitation (EA) is defined as a state of disorientation associated with confusion, restlessness, involuntary movements, and inconsolability. EA causes an increased risk of postoperative complications. This study compares the effectiveness of dexmedetomidine and propofol in preventing EA in children undergoing surgeries using sevoflurane anesthesia. Methods -This prospective randomized double-blind study was conducted from March 2022 to Oct 2023. A total of one hundred were included in the study and randomized to two groups. One group received dexmedetomidine and the other propofol to prevent EA. Pain scores, agitation scores, and sedation levels were compared as per study protocol between the two groups. Results- In our study incidence of EA was higher in the dexmedetomidine (n = 13) group in comparison to the propofol group (n = 5) (p<0.05). A significantly lower mean Observational Pain Score (OPS)was observed among the dexmedetomidine group as compared to the propofol group after extubation (p < 0.05). Also, . Post extubation mean heart rate was significantly lower in Dexmedetomidine group as compared to Propofol Group. Conclusion- Dexmedetomidine may provide significant benefits in providing post-op pain relief in comparison to propofol however incidence of emergence agitation appears to be higher with dexmedetomodine when compared to propofol as found in this study. Larger, randomized multicentre trials with appropriate sample sizes will be required to further evaluate the efficiency of these drugs in the prevention of EA.

RIPER, anantapur
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
2. What are the interventions
available?
• Oxygen
• CPAP
• Mechanical Ventilation
• Surfactant
Dr Ajay Agade
3. Surfactant Replacement Therapy
• Does it work?
• When to give?
• Which one to give?
• How often to give?
• How to give?
• Does it cause any problems?
Dr Ajay Agade
6. • Odds of death in hospital for VLBW infants were
reduced by 30 % after surfactant was introduced.
• 80% of decline in the U.S. neonatal mortality rate
between 1989 & 1990 could be attributed solely to
the use of surfactant.
NEJM May 1994
Dr Ajay Agade
7. Exogenous surfactant replacement has been
established as an appropriate preventive and
treatment therapy for prematurity-related
surfactant deficiency
AMERICAN ACADEMY OF PEDIATRICS
Committee on Fetus and Newborn March 1999, pp 684-685
Dr Ajay Agade
8. Indian Experience
• The mean duration of ventilation 44.1 hours
lesser, and the hospital stay 4.37 days lesser in
babies who received surfactant.
• The incidence of
sepsis, pneumonia, PDA, IVH and CLD was
lower in babies who received surfactant.
Narang et al Indian Pediatrics 2001
Dr Ajay Agade
11. Comparative trials demonstrate greater early
improvement in the requirement for ventilator
support, fewer pneumothoraces, & deaths
associated with natural surfactant.
Natural surfactant may be associated with an
increase in IVH, though the more serious
hemorrhages (Grade 3 and 4) are not increased.
Despite these concerns, natural surfactant extracts
would seem to be the more desirable choice when
compared to currently available synthetic
surfactants.
Cochrane 2005
Dr Ajay Agade
13. •The animal surfactants have phospholipid compositions similar to
that of natural surfactant; they contain some SP-B and SP-C, but
no SP-A.
• The surfactant approved for use in the United States is Survanta
(beractant, Ross Laboratories, Columbus, Ohio) prepared by
mincing bovine lungs in saline and extracting the lipids, SP-B, and
SP-C with organic solvents.
Dipalmitoylphosphatidylcholine, palmitic acid, and triglyceride are
then added to improve the surface properties of the extract
•. The surface properties of organic-solvent extracts of lung tissue
also can be improved by removing neutral lipids by
chromatography, as is done with Curosurf
Dr Ajay Agade
14. Absence of Surfactant
High Distending Pressures
Airway Stretch / Distortion
What happens ?
Cellular Membrane Disruption
Edema / Hyaline Membrane Formation
Higher FIO2 / Pressures
Barotrauma, BPD
Dr Ajay Agade
17. There is no indication that exogenously administered
surfactant inhibits the synthesis and secretion of
endogenous surfactant
Two major benefits result from surfactant treatment:
The biophysical effects of the surfactant on the
surfactant-deficient lungs
And the provision of phospholipids as substrate
for recycling pathways
Dr Ajay Agade
19. The meta-analysis (50) indicated that there
would be two fewer pneumothoraces and
five fewer deaths for every 100 babies
treated prophylactically with surfactant.
Dr Ajay Agade
20. •Prophylactic treatment during the first 15 minutes of life
appears to be more effective
BUT not all infants that would appear to be at risk of
developing RDS, actually develop the condition.
May lead to some infants being over treated, and possibly
being exposed to adverse effects, unnecessarily.
Dr Ajay Agade
22. Multiple doses of surfactant have been given in most
trials because the response to an individual dose is often
transient.
In preterm animals, exogenously administered surfactant
is can be inhibited by soluble proteins and other factors in
the small airways and alveoli.
Multiple doses are thought to be useful because they can
overcome this functional inactivation of surfactant.
Pediatrics 1991
Dr Ajay Agade
24. Antenatal steroids & surf
• Synergistic effect
Prenatal steroids + Surfactant is better than
either alone
• neonatal mortality
• air leaks Give both
• severe IVH
Am J Obst Gynec Suppl, 1995
Dr Ajay Agade
25. • A secondary analysis of data from
surfactant trials also indicates a greater
reduction in disease severity in babies
who received antenatal steroids
(evidence level 4).
• Combination of antenatal steroids is
more effective than exogenous
surfactant alone (evidence level 2b).

Dr Ajay Agade
27. INSURE procedure
Early surfactant replacement therapy with
extubation to N CPAP compared with continued
mechanical ventilation with extubation is
associated with a reduced need for mechanical
ventilation and increased utilization of exogenous
surfactant therapy.
COCHRANE 2005
Dr Ajay Agade
28. HOW SHOULD VENTILATORY MANAGEMENT
AFTER SURFACTANT THERAPY BE
APPROACHED?
“ Options for ventilatory management that are
to be considered after surfactant therapy
include very rapid weaning and extubation to
CPAP (grade B evidence).”
Dr Ajay Agade
30. WHAT ARE THE RISKS OF EXOGENOUS SURFACTANT
THERAPY?
Dr Ajay Agade
31. The short-term risks of surfactant replacement therapy
• Bradycardia and hypoxemia during instillation,
• Blockage of the endotracheal tube
• Increase in pulmonary hemorrhage following surfactant
treatment
• However, mortality ascribed to pulmonary hemorrhage
is not increased and overall mortality is lower after
surfactant therapy.
Dr Ajay Agade
33. Cost implications
• Surfactant is expensive
• 22% reduction in hospital charges per
survivor
• 52 % Reduction in ancillary charges
Dr Ajay Agade
34. Does surfactant fail?
• Extremely preterm infants with structurally lung
immaturity
• Pneumonia or pulmonary hypoplasia
• Perinatal asphyxia
• Pulmonary edema from lung damage or fluid
overload
• Pulmonary edema from L-R shunting through
PDA
• Congenital B protein deficiency
Dr Ajay Agade
Thanks m for explaining us the physiology in detail…moving on to the next part of presentation….as already introduced rds is a big prob in preterm babies and the risk exponentially rise with decreasing gestation…as much as that 80% of babies below gestation 27 weeks may land into rds…
So what are the interventions avaible….starting with basics of essential newborn care including the the temp management fluid and elctrolyte calculation along with managing oxygenation and ventilation constitutes the management of respiratory destress syndrome previously called as hmd….many of them will do fine with simple intervention mentioned…some will require cpap and some might require advance therapies like surfactant therapy………this presentation focuses on the surfactant therapy in rds…
The first and formost question is does it work…what is the proper timing to give …..which type whether natural or synthetic….how many doses…then we will be discussing what is the methodology
So the first question is does it wotks…being a novel therapy many of us are not comfortabel with surfactant therapy..the critics qustion its usefullness and those who are convinced raise the question of being costly and its cost effectiveness….this presentation is based upon the evidences collected from databse…
If we search neonatal databases maximum rcts in neonatalogy are attributed to surfactant therapy ….most of the systemic reviews and metaanylysises gives us good strength in answering the questions I put in the first slide
In may 1994 NEJM published a very significant data which concluded that
Within 5 years of the previous publication aap labaled exogenous surf therapy as standard preventive and therpeutic modality of management in case of prematurity related surf def..in front of u on the screen is the statement issued by commete on fetus and newborn….
So what is the indian status the first case controll study came in 2001 by narang which concluded that both the duration of ventilation and hospital stay reduced significantly in treated patients,…..secondly the complication which are in fact more with prematurity where also found to be reduced which was attributed to the overall respiratory well being of these patients…..this was one of the first kind of studies which prooved cost effectiveness of surfctant despite the critisism in our country….
Pramarily of two types the natural ones these are the Animal lungs extracts and the sunthetic one..what intersts us here is the natural one.. I ll be discussing this over next few slides…The natural ones are prepared from variety of animals..from bovine its called as survanta…calflung its called exosurf and porcine called as curosurf….
Lets see what the databse says about tis…In 2005 cochrane stated that natural surfactant decreases ventialtoty requirement and also other complication….. Although it increases chance of IVH but if compared to the currently available synthetic product they are all the way superior
So cochrane came with final conclusion that ……
Lets try to underastand this on pv loop If we compare the efficacy of available surfactants here on this pv curve it clearly seems that the lower opening pressure required are much less with natural surfactant …further if we compare the opening pressures amongst natural one sheep extract scores highest in efficacy….we in our unit use cursosurf whose efficacy lies between sheep extract and survanta…..
This is simple digram depicting alveoli with deficient surfactant because the surface tension working inside the alveoli, the alveoli tend to collapse….because of surfactant in alveoli the collapsibility decreases….This small video explain the physiology..i don’t know its visible properly…coin is floating over water because of surface tension..now if we administer surf…the air liquid interface breaks and coin sinks…..
If we try to understand this on respiratory mechanics it will look like this…This is pressure volume loop showing difference between rd lung and normal lung…if we see the lower opening pressure in rds its 15..its less than 10 somewhere here…if u see the change in volume with pressure there is exponential rise and exponential decay in normal lung while its very very poor in hMD…..as we all know minute ventilation is a basic of respiratory function…..
Now the last querry which chalanges the usefullness is whether surf interfers with the normal physiology answer is no….surf do not inhibit the synthesis of endogenous surf……in fact not only surf has postive effect on lung mechanics it also gets recycled in making of natural surf
Timing of surf administration emerged as single most important factor as for as the outcome of rds is concerned….administering the surfactant within two hours of birth as a matter of fact in labour room itself is called as prophylactic therapy…….these patients are identified as at risk of RDS depending on gestation and then selected for prohylactic therapy (jusifiable in 27 weeker where incidence is very very high)…another form is administering surf once the signs and symp develop or after radiological cinfirmation this is called as rescue therapy…….this is further divided in early and late rescue depending upon the timin after disgnosis….
So what the database has to asy about this…The metanalysis done from pooled data of 5o rct revealed that there will be less comlication and less death with prohylactic therpy….although this is an establisted fact that prophylaxis is better than rescue I want to bring to an attention some practical problems with prophylaxis therapy…..lets se
What are the facts regarding ……..We had the twins one developed rds another remained stable
Before we procede to actual procedure I want to emhasis the importence of antenatal steroids…eventhogh we have a novel drug with us now we should never forget the importence of an steroids as cornerstone in preventing occurrence and severity of rds. Its been 100 year eve more an steroid still hold their position
……the established facts are
Start video…pause focusing subject…give details bout history no antinatal steroids… gestation symptopms ….show xary …start video again….take pauses when reqd….B/0 priyanka…born to a primi mother with gestation of 31 weeks weighing 1990 grams..developed sign syp of rds within 2 hours and we decided to treat this baby wid surf…I want to emphasise here that they did not received an steroids…..
What was done next on this baby was something called as INSURE protocol…..it says….so we follows exactly the same…..
Lets see what the evidence has to say….it says that
This is our baby which was extubated within 4 hours of surf therapy…baby was put on buble CPAP and then further weaned to oxygen by hood and with good supportive therapy we were able to discharge this baby on …day of her life
Coming to the last part of discussion…its time to duscuss the problems of surfactant administartion
Increase in ph as compares to normal term subjects….If u compare wit incidence of ph in preterm itself its very less…on the contrary by preventing the complication of prematurity its actually reduces the incidence of ph
Surf is expensive yes its true….1.5 ml of surf cost arround 12000 however it should alwys be kept in mind that This was already prooved in mumbai based study of narang
Yes first and foremost thing is the skills…monitoring ventilatory strategy and supportive therAPY….most important in surf therapy is insure…what are the other things ……
