In infancy, there are specific features

concerning both natural and violent death

natural death

Medicolegal task for forensic pathologist is

to assess:

1. if it is a newborn or an older child

2. maturity of a newborn baby or fetus

(gestational age)

3.  infant's viability 

4.  whether the child was born alive /

duration of life

5.  the cause of death / the time of death

6.  identity of an unknown mother

1. Estimation if an infant is a newborn 

or an older child

newborn period immediately after delivery

- WHO definition - the first four weeks

- some pediatricians and forensic pathologist 

- the first week 

signs of recent delivery

external:

- skin - cyanotic, blood, maeconium, vernix 

- umbilical cord - soft, wet

- falls of after 5 to 7 days

2. Estimation of maturity

of a newborn baby or a fetus

estimation of gestational age

traditional formulae – the Haase rule

the first 5 months (20 weeks) of gestation

the length of the body in cm equals thesquare of the age in months 

in the 3 rd  month the length is 3 2  = 9 cm  

the last 5 months (21 to 40 weeks) of gestation the length of the body in cm equals five

times the age in months 

in the 7 th  month the leng th is 7 x 5 = 35 cm

3. Estimation of an infant s viability 

the potential ability of an infant

to survive after birth

3 main factors:

1. maturity of an infant

2. absence of life-threatening diseases 

3. absence of anomalies incompatible with life

3. Estimation of an infant’s viability 

termination of pregnancy

up to 28 weeks  – abortion or  miscarriage

from 29 to 38 weeks - premature birthfrom 39 to 40 weeks - mature birth

- up to 28 weeks – abortion or miscarriage - fetus

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 72/186

up to 28 weeks    abortion or  miscarriage  fetus

is not viable due to the immaturity of the body

- owing to the modern medicine, a fetus of even

24 weeks can potentially survive given intensivehospital care

- the age of viability  in English law was taken as

28 weeks' gestation, though this has now been

reduced to 24 weeks

The remains of a fetus  recovered from asewage farm – the result of an abortion. Thereis considerable maceration of the body. The

gestational age was 16 weeks  –  the baby wasnot viable, so that no further action wasrequired.

Death occurs due to the baby’s  immaturity  –  fatal

3. Estimation of an infant s viability 

from 29 to 38 weeks - premature birth

- an organism of a prematurely born child is

immature, primarily regarding state of the

lung and respiration, with possible

development of respiratory distress

syndrome 

- the prematurely born child may stay aliveonly under the special medical conditions

and care - conditional capability of life

from 39 to 40 weeks - mature birth

- If the child is born between 38 and 40 weeks

of pregnancy, its organism is mature and

viable

- the child may survive, if there are no life-

Alveoli containing squamous cells from the vernix

caseosa of the fetal skin. When these are abundant

and lying free in the alveoli it suggests that the child

has not breathed.

In this case of meconium aspiration, small rounded balls of meconium are

seen in an alveolus, along with flattened "squames" or desquamated fetal

skin cells that are found in the amnionic fluid. Meconium is an irritant that

Infanticide Acts in England and Wales 

Where a woman  by a wi l l fu l  act o f om iss ion o r

Four prerequisites must be fulfilled:

Q

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 176/186

1. The mother  is only perpetrator2. The child  has to be less than a year old

(the majority occurs within hours or even

minutes of birth)

3. The victim has to be a living "child"

4. Death has to be caused by a willful act of

omission or commission, at the time the

balance of the mother's mind wasdisturbed due to the childbirth or lactation 

In many countries the infanticide is legally

treated as privileged homicide which is less

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 177/186

treated as privileged homicide which is less

severely sentenced comparing to pure

homicide - e.g., in England as manslaughter

- a less serious charge than murder, without

the mandatory penalty of life imprisonment

(sentences are probation or psychiatric

supervision). 

MEDICOLEGAL ASPECTS OF UNCLEAR

DEATHS IN INFANCY

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 178/186

In all cases of unclear death in infancy, amedical practitioner must be very careful,

always keeping in mind the possibility that

some deaths caused be injuries due toinfanticide or child abuse may be

deliberately presented as natural by

perpetrators of homicide. In such cases theusual explanations are presented as a

history of stillbirth or SIDS. 

Meadow , R. (1999) Unnatural sudden infan t death.

Arch Dis Ch ild , 80(1): 7-14.

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 179/186

81 cases from 50 families (during the 18-year-period)  –  after medico-legal autopsy and

investigation, a natural manner of death was

determined, under the circumstances typical for

SIDS

By means of further investigation procedure and

detailed medicolegal examination, it was

positively proved that babies were killedperpetrator – mother

method – smothering

Because of that, all alleged stillbirths which

were not witnessed by a doctor or midwife,

8/11/2019 Death and Injury in Infancy

http://slidepdf.com/reader/full/death-and-injury-in-infancy 180/186

as wall as all supposed SIDS  cases should

be reported for medico-legal investigation.

The only way to positively clear up the realcause and manner of death is to perform

thorough medico-legal autopsy and all other

additional investigations  (microscopical,

toxicological, microbiological, etc.) in

accordance with each particular case.
