It is the term used for people whose height is below the average compared to their peers’ height. This term is most commonly used for children, but also can be applied to adults. As children can be shorter than their friends or peers and still perfectly healthy. This case occur when the adult height is more than two standard deviations less than the known degree of shortness.
Causes and classification:
1- Structural growth delay:
Simply, in children the growth may be delayed than others, which are called late bloomers. They usually reach the puberty later than children of their age, and their growth will continue after others of the same age and the normal height rate.
2- Genetically:
It may called familial short stature or genetic short stature. In this case the person will have abnormal height rate lower than others at the same age throughout his life. . The bone age formation is with the chronological age. This is the most difference between the familial short stature and those of delayed growth.
3- Disease:
- Endocrine diseases: which will affect the production of hormones. Some of this hormones that affects the growth and the height are thyroxin (hypothyroidism), growth hormone (growth hormone deficiency), and Cushing’s disease.
- Chronic diseases: they effect on the overall health. Such as, kidney disease, heart problems, bronchial asthma, bowel inflammation, diabetes, rheumatoid arthritis, and sickle cell anaemia.
- Genetic conditions: Down syndrome, Williams syndrome, and turner syndrome.
- Skeletal and bone diseases: rickets, achondroplasia that change the structure by their effect on the growth of bones.
4
- Also some problems or diseases during pregnancy or malnutrition have effects on the height of the child. (Lacey et al, 1974)
4- Other normal and biological causes:
- According to Binder (2011), it is a case in which the person is 2 SD from the known normal ranges, and there is no evidence for endocrine problems or delayed growth. The short stature, in this case, occur due to some variations (genetic variations) which have large effects, such as SHOX gene. This gene is responsible for 1% to 4% of the cases of the short stature. This is known by Idiopathic short stature.
- Some causes of short stature cases may be because of the premature delivery of infants. Premature infants continue with this problem to the childhood, which is known by small for gestational age.
- Cartilage extracellular matrix as the collagen and another proteins that is responsible for the growth of cartilage.
- Control of growth plate function by the effect of cytokines, so the repeated inflammatory diseases cause slowing of the growth plate, because the catch up of the growth delayed after the effect of cytokines resolved.

Intrauterine growth restriction when to deliver by dr alka mukherjee & dr apu...alka mukherjee
Molecular basis of IUGR. –
1. Atypical expression of enzymes governed by TGFβ causes the placental apoptosis and altered expression of TGFβ due to hyper alimentation causes impairment of lung function.
2. Crosstalk of cAMP with protein kinases plays a prominent role in the regulation of cortisol levels.
3. Increasing levels of NOD1 proteins leads to development of IUGR by increasing the levels of inflammatory mediators.
4. Increase in leptin synthesis in placental trophoblast cells is associated with IUGR.
A positive history for risk factors of IUGR can raise the problem of an increased surveillance with the specific goal of an early detection of growth insufficiency [23]. Further diagnostic tests could have a better relevance in a selected high-risk population
Serum markers linked to IUGR
The placentation process starts with the migration of trophoblastic cells that invade the walls of spiral arteries and transform them from small caliber high resistant vessels into wide caliber low resistant vessels that deliver blood at low pressure to the intervillous space. Then, the utero-placental circulation develops in two stages: the first stage (until the 10th week of gestation) consists in endovascular plugging of the spiral arteries by trophoblastic cells, subsequently followed by invasion and destruction of the intradecidual spiral arteries; the second stage (between 14-16 weeks of gestation) consists in the invasion of the inner miometrial part of the spiral arteries [27]. The impaired spiral artery transformation is leading to weak development of the utero-placental circulation and is implied in the pathology of preeclampsia and IUGR
Pregnancy associated plasma protein A (PAPP-A), an Insulin–like Growth Factor Binding Protein Protease whose levels depend on placental volume and function, was assessed in several studies with congruent results. In 2000, Ong et al. evaluated 5584 singleton pregnancies at 10-14 weeks of gestation and measured maternal serum free beta human chorionic gonadotropin (β-hCG) and PAPP-A, concluding that low levels of maternal serum PAPP-A or β-hCG were associated with subsequent development of pregnancy

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
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.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
2. Introduction
• Growth is characterized by an increase in size of the body – in height, weight
and other measurable areas. Growth can be divided into fetal, infancy,
childhood and pubertal phases.
• Development is qualitative. It refers to physiological, social and psychological
maturation. It is the gaining of behavior and skills
3.
4. Parameters of growth
1. Target height
2. Growth velocity
3. Bone age
4. Body proportions
5. Arm span
6. Weight-for-Height Ratio
5. Height measurement
1. Height should be measured with the child
standing back to the wall with head in
Frankfort horizontal position, heels at the
wall, ankles together, and knees and spine
straight against a vertical metal rule.
2. Height is measured at the top of the head by
a sliding perpendicular plate (or square
wooden block).
3. A Harpenden stadiometer is a mechanical
measuring device capable of such accurate
measurement.
6. Target height
Mid parental height
1. Boys: [(mother’s height + 13) + father’s height] / 2 cm +/- 8.5 cm.
2. Girls: [(father’s height -13) + mother’s height] / 2 cm +/- 8.5 cm.
3. Child should achieve within 8 cm of midparental height. A range 8 cm above
or below this predicted height is considered within the 3rd to 97th
percentile.
4. A child whose current height percentile differs greatly from his or her target
percentile is considered short for his or her genetic potential
7. Growth velocity
• Growth velocity is change in height (cm) / year.
• Growth velocity is 25 cm in first year; 12.5 cm in second year; 6 cm/year till puberty
• Height:
• At birth: 50 cm
• 1 year: 75 cm
• 4 years: 100 cm
• 8 years: 125 cm
• 12 years: 150 cm
• Poor linear growth is defined as linear growth velocity more than 2 SDs below the mean
10. Skeletal maturation:Bone age
• Epiphyseal centers obtained on
radiography is compared with
published standards.
• Greulich and Pyle (GP) and the Tanner
e Whitehouse (TW2) method.
• Xrays:
• knee: < 3yers
• wrist: < 6 yers
• Elbow: > 6 yers
11. Body proportions
The upper-to-lower body segment (U/L) ratio
• Normal proportion
• At birth: 1.7
• 3 years: 1.3
• 7 years: 1.1
• 10 yeras: 1
12. Arm span
1. Equal to height in 8 years of age
2. Arm span can be measured as the distance
from left fingertips to right fingertips in a
patient standing, arms spread, against a wall.
3. Used as a surrogate for height who have
scoliosis, spina bifida, or leg contractures or
after spinal irradiation.
13. Weight-for-Height Ratio
• Increased: Obesity in endocrine disorders:
1. GH deficiency
2. Thyroid hormone deficiency
3. Glucocorticoid excess (Cushing’s disease)
• Decreased: Thin for stature in systemic disorders like:
1. Malnutrition
2. Chronic illness etc.
15. Definitions
1. Short stature is defined as a height less than two standard
deviation or below the third percentile for that population.
2. More than two standard deviations below the midparental height
3. The child is consistently having a poor growth velocity i.e. height
deceleration across two major percentile lines on the growth chart
16. Practical Classification of short stature
Proportional:
1. Equal height weight ratio: GHD
2. Weight more than height: Cretinism, Cushing
3. Height more than weight: Chronic illness, Malnutrition
Disproportional:
1. Short limb: Achondroplasia
2. Short trunk: Hurler, Hunter, Morquio
17. Classification of short stature-II
1. Physiological:
1. Familial short stature
2. Constitutional growth delay
2. Pathological:
1. Growth hormone deficiency
2. Insulin like growth factor-1
deficiency
3. Hypothyroidism

2. Fibrous dysplasia
11. Chromosomal:
1. Autosomal:
1. Down
2. Prader-Willi
3. Noonan
2. Sex chromosome:
1. Turner
20. Familial Short stature
1. Father or mother is short
2. Normal weight and length at birth
3. Growth velocity is decreased in first two years and then resumes normal
growth
4. Bone age and puberty are normal
5. Adult height is appropriate for the family
22. Constitutional growth delay
1. Normal parents
2. Normal weight and length at birth
3. Growth pattern is similar to FSS
4. Delay in bone age
5. Delay in onset of puberty, reflecting the pattern of one parent.
6. Growth is decreased in first 3 years
7. But growth continues beyond the average period of growth.
8. Finally reaches the target height
24. Growth Hormone Deficiency
• Hypopituitarism :
1. Incidence is 1 in 4000-10,000
2. Multiple hormone deficiency- 20%
3. Isolated growth hormone deficiency- 13%
• Growth hormone:
1. Secreted by ant.pituitary; stimulated by GHRH; inhibited by somatostatin
2. GH released in response to sleep, exercise and hypoglycaemia
3. Promotes growth by stimulating insulin like growth factor: IGF1
25. GH Deficiency
1. Mutation : Septo optic dysplasia:
1. incomplete development of septum pallucidum,
2. optic nerve hypoplasia, Midline abnormalities in brain
3. Nystagmus , Visual impairment, Ant and post hormone deficiency

35. Body Proportion
• Decreased U/L ratio for age:
1. Skeletal dysplasias involving primarily the spine (eg, spondylodysplasias)
2. Eunichoidism
3. Delayed or incomplete puberty (eg, Klinefelter or Kallmann syndrome)
• Increased U/L ratio
1. Those dysplasias involving especially the long bones (eg, achondroplasia)
2. Because puberty is associated with relatively greater truncal than limb
growth, an increased U/L ratio for age may be seen in precocious puberty.
36. Bone age
• Familial short stature (FSS) is associated with normal skeletal maturation
• Bone age is delayed in:
• constitutional growth delay,
• malnutrition, and
• endocrine causes of short stature (eg, hypothyroidism, cortisol excess, growth
hormone deficiency)

45. Disproportionate short stature
1. Skeletal dysplasias: Achondroplasia:
2. the cartilage cells developed into bone more slowly than normal in the long
bones of the arms and legs, leading to shorter bones and shorter overall
height.
3. The trunk is relatively normal in length but the arms and legs are short with
more proximal shortening.
4. ‘fibroblast growth factor receptor-3’(FGFR3) is defective

50. Familial Tall Stature
• Children with familial tall stature are usually tall from an early age (2 years of
age or younger) with one or more parents who are also tall. They have a high
normal growth rate and bone age consistent with chronological age.
• Clinical examination and evaluation of parental heights are all that is required
to confirm the diagnosis.
• If there is one tall parent and one normally statured parent, consideration
should be made of the possibility of an autosomal dominant condition (such as
Marfan syndrome) before making a diagnosis of familial tall stature.
51. Constitutional tall stature
1. Children are born of normal stature and grow rapidly during the first 4 years of
life; after which growth velocity drops and becomes parallel to the 50th centile.
2. Bone age may be slightly advanced.
3. Puberty is usually within the early normal range and final height usually within
the target range.
4. Children with obesity from early childhood are usually tall with a slightly
advanced bone age.
52. Precocious Puberty
1. Although precocious puberty results in a reduction in final height due to
restricting the number of years of prepubertal growth, at the time of onset
of puberty, height is generally increased.
2. Therapy should be directed at the underlying pubertal disorder and most
commonly involves GnRH analogue therapy for gonadotropindependent
precocious puberty that decreases sex steroid production and IGF‐I
concentrations, thereby reducing growth rate.
53. GH Excess
1. GH excess is extremely rare.
2. Causes include:
1. GH‐secreting pituitary micro‐ or macroadenomas,
2. Ectopic GHRH production and
3. Genetic abnormalities affecting GH secretion (mccune–albright syndrome and carney
complex).
3. Benign GH‐secreting adenomas are the most common cause of GH excess.
4. The commonest symptom is rapid growth.
54. Syndromes Associated with Tall Stature
1. Klinefelter Syndrome and 47,XYY: The legs are long and arm span is usually greater than
height. A rapid increase in growth velocity is seen during the childhood period but the
adolescent growth spurt is not of increased magnitude. Thus boys with Klinefelter
syndrome who are normally statured at the beginning of adolescence can be reassured
that their final height will not be increased
2. Marfan syndrome is an autosomal dominant multisystem connective tissue disease
caused by mutations in the fibrillin 1 gene.
3. Homocystinuria is an autosomal recessive trait caused by loss‐of‐function mutations in the
gene encoding cystathionine beta‐synthase. Affected individuals are tall and thin with
increased arm span. Other clinical features shared with Marfan syndrome include pectus
deformities, myopia and scoliosis.
55. 4. Sotos syndrome (also called cerebral gigantism) is a sporadic disorder caused by mutations
or deletions in the NSD1 gene. It is characterized by macrocephaly, dysmorphic facial
features (high broad forehead, long narrow face, down‐slanting palpebral fissures,
prominent jaw), poor coordination and learning difficulty.
5. Weaver syndrome is phenotypically distinct from Sotos syndrome with hypotonia,
looseness of skin, wide philtrum, deep‐set nails and advanced bone age (not found in
Sotos syndrome) and is caused by autosomal dominant mutations in EZH2.
6. Beckwith–Wiedemann syndrome is characterized by overgrowth including visceromegaly
and hemihypertrophy, ear lobe creases, hypoglycaemia, omphalocele and an increased risk
of tumours. The genetic causes of Beckwith–Wiedemann syndrome are complex and
include paternal uniparental disomy of chromosome 11 and hypermethylation at the H19
differentially methylated region, both of which lead to increased expression of IGF‐II.
57. Management of Tall Stature
1. There is usually no medical reason for treatment of tall stature and the decision to treat is based
upon the acceptability for the patient and parents of the predicted final height.
2. In boys the treatment has traditionally been the use of intramuscular injections of testosterone
esters given at supraphysiological doses – up to 500 mg/m2/ month (given as 1–2 injections per
month).
3. In girls high‐dose oestrogen treatment was most commonly given as oral ethinylestradiol at 100
μg/day (physiological adult replacement is equivalent to 30 μg/ day) in combination with an oral
progesterone for 7–10 days per month. Mean reductions in height of up to 6 cm were observed
and similarly to boys, treatment was more effective when started at a lower bone age.
4. Early induction of puberty with physiological doses of testosterone in boys and oestrogen in girls
may be beneficial, without the additional risks of high‐dose oestrogen therapy.
