“…The value of the fetal collection was confirmed in numerous previously published scientific studies (27)(28)(29)(30)(31)(32)(33). The scientific experience of the team has been confirmed in many works using anatomical scientific methodology and anatomical techniques used for statistical analysis (34)(35)(36).…”

Background:The progress of pediatric surgery and increasingly better diagnosis of fetal defects require detailed knowledge of human developmental anatomy. Precise knowledge of the anatomy of innervation of the lower extremities corresponds to this subject and is not only cognitive but also clinically important. The end of the common fibular nerve is superficially located in the area exposed to frequent injuries as well as in the area subject to possible surgical repair procedures. Materials and methods:The analysis was carried out on 200 human foetuses aged from the 113 th day to 222 nd day of foetal life. The study material is a part of local fetal collection. The study incorporated the following methods: anthropological, preparational and image acquisition which was acquired with the use of high-resolution digital camera. Statistical analysis was carried out with the use of STATISTICA package. Results:Based on the research results the new typology of the examined nerve was determined. The head of the fibula was the criterion: (i) high divisionabove the head of the fibula (1%); (ii) intermediate divisionat the height of the head of the fibula (34%); (iii) low divisionbelow the head of the fibula (65%). The mathematical analysis did not reveal statistically significant bilateral and gender differences. Moreover the additional branch was observed in 30% of fetuses, regardless of age class. This branch occurred in 50% of cases in both sides of the fetus. This nerve was defined as the accessory fibular nerve (nervus fibularis/peroneus accessorius). Conclusions:The created unique typology of the terminal division of common fibular nerve is an important supplement to the anatomical knowledge and at the same time, due to the peripheral and superficial location of the described structures, it has a relatively high clinical significance.

“…when mummies with metaphyseal and/or diaphyseal lines were counted and also a higher prevalence of 57% (12 out of 21) when only mummies with the typical diaphyseal lines were counted. In contrast to adults, diaphyseal transverse lines are more likely not resolved as the individuals were young (Kulus & Dąbrowski, 2019). However, early death of the children in the study reduced the years in which new transverse lines could have developed.…”

“…Compared with the reported prevalences of Harris lines in a little over 30% (Gray, 1967) and in more than 50% (Lichtenberg, 2015) in collections of predominantly adult ancient Egyptian mummies, the collection of child mummies in this study had a substantially higher prevalence of 71% (15 out of 21) when mummies with metaphyseal and/or diaphyseal lines were counted and also a higher prevalence of 57% (12 out of 21) when only mummies with the typical diaphyseal lines were counted. In contrast to adults, diaphyseal transverse lines are more likely not resolved as the individuals were young (Kulus & Dąbrowski, 2019).

The aim of this study was to investigate the prevalence and anatomical distribution of recovery lines (growth arrest lines) in ancient Egyptian child mummies. Wholebody computed tomography (CT) examinations of 21 ancient Egyptian child mummies from European museums were evaluated for estimation of age at death and sex of the children. CT examinations were systematically assessed for recovery lines by inspection for metaphyseal lines, diaphyseal transverse lines, and bonewithin-bone appearance at several sites of the skeleton. The estimated age at death of the children ranged from about 1 year to the age of 12-14 years. Twelve children were assessed as male, seven as female, and in two, the sex was indeterminate.Recovery lines were found in 18 out of the 21 (86%) child mummies. Metaphyseal lines were present in 12 mummies (57%), diaphyseal transverse lines in 12 mummies (57%), and bone-within-bone appearance in 11 mummies (52%). One case showed particularly dense metaphaseal bands typical of lead lines in lead poisoning. In conclusion, systematic assessment of recovery lines on CT images of ancient Egyptian child mummies showed a high prevalence of these lines. Many children had a combination of different lines, indicating more than one episode of growth disturbance. The spectrum of recovery lines included the better known metaphyseal and diaphyseal transverse lines as well as the less known bone-within-bone appearance that share the same pathomechanism. The mummy with lead lines seems to be the first case of radiological evidence of lead poisoning from ancient Egypt.

“…The boy's biological age was estimated by X‐ray based on development of the permanent teeth (Smith, 1991; Štepanovský et al, 2017). Skeletal developmental anomalies and growth abnormalities (Scheuer & Black, 2000), including nonspecific stress indicators on the frontal permanent teeth (LEH; King et al, 2005) and long limb bones (HL; Lewis & Roberts, 1997; Kulus & Dąbrowski, 2019), were evaluated, also using X‐ray (Department of Anthropology, National Museum, Prague). The age at LEH formation was estimated using Reid and Dean's (2000) standards for the timing of anterior tooth growth.…”

Although First World War battles did not directly affect the territory of all participating states, the conflict brought suffering in the form of a decline in their inhabitants' economic situation. This was also true in the Czech Lands. Opportunities for studying the impact of the period's difficult living conditions on the human body are very limited. This study presents pilot research into the possible influence of the wartime environment on children's lives through the example of a 10-year-old boy (1907)(1908)(1909)(1910)(1911)(1912)(1913)(1914)(1915)(1916)(1917) from a family of landowners. The circumstances of his death and burial, demonstrated in coffin adjustment, confirm that the war influenced conditions at the time. We therefore considered the possible osteological and nutritional manifestations of the stress of that time, such as difference between biological and chronological age, the presence of skeletal developmental anomalies, signs of nonspecific stress in the form of linear enamel hypoplasia and Harris lines, and diet, also in the family context. The results showed no significant difference between the boy's biological and chronological ages nor body height disorder. There were seven developmental anomalies on his skeleton, some also found in other family members, which supports documented family relationships. Co-occurrence of signs of nonspecific stress and isotopic shifts were also found, indicating the possible presence of nutritional stress before his wartime death.
