Accidental Hanging Deaths in Children in
Konya, Turkey Between 1998 and 2007*
ABSTRACT: In general, hanging cases are the result of suicide, and accidental and homicidal hanging cases are rarely seen. This study ret-
rospectively investigated 4571 death examinations and autopsies that were performed at The Konya Branch of the Forensic Medicine Council
(Turkey) between 1998 and 2007; hanging was involved in 201 (6.5%) of the cases. There were a total of 13 accidental hanging cases, where
12 of these involved children. In seven of the cases, the accidental hanging involved a scarf that wraps around swing-like cradles and is
intended to prevent infants from falling down. It was concluded that accidental hanging deaths can be reduced by replacing swing-like cradles
with cribs that are designed for children, removing ropes in and around the house, and preventing children from reaching and or playing with
rope-like objects.
KEYWORDS: forensic science, hanging, asphyxia, children, death, accident
Children have an increased risk for injury or death from acci-
dents for a variety of reasons compared to adults. Perhaps the
greatest reason is their natural curiosity, which leads them to
explore their environment and investigate situations where they
often do not recognize potential hazards (1). Nevertheless, acciden-
tal hangings are still very uncommon in the pediatric population
(2,3). Most reported cases of hanging occur in adults, and the
majority are attributed to suicide (4). A number of articles have dis-
cussed the general features of hanging and several have included
cases involving child victims (4–6). Unlike adult hangings, cases
involving children are typically accidental and most frequently
occur in the childs bedroom (3,4). The present study evaluated the
circumstances of 12 accidental hanging cases that involved
children.
Materials and Methods
This study retrospectively investigated 4571 death examinations
and autopsies that were performed at The Konya Branch of the
Forensic Medicine Council (Turkey) between 1998 and 2007;
hanging was the cause of 201 (4.4%) of the deaths. There were a
total of 13 (6.5%) accidental hanging cases and 12 of these
involved children. The present study evaluated those 12 cases
with respect to their demographic characteristics, the location of the
incident, the manner of the incidents that took place, and the
findings of the scene investigation and autopsy.
Results
The ages of the cases ranged from 6 months to 11 years, with
an average age of 3.4 3.9 years. There were ten boys and two
girls. In seven cases, death resulted from entanglement with a
ligature (scarf, handmade sash, braid rope) that was wrapped
around a handmade swing-like cradle (e.g., hammock), which
wasintendedtopreventthebabyfromfallingdown(Table1,
Fig. 1). As the infant leaned out of the cradle, the ligature
wrappedaroundhisher neck and caused the asphyxiation. Three
of the cases involved a rope in the yard of the home. Of the
remaining two cases, one involved a rope hanging down from a
construction wall and the other occurred when the childs neck
was entangled in a tight electrical heater cable while he was
crawling on the floor (Table 2). The scene investigations and
autopsies determined that all 12 deaths had occurred as a result
of hanging.
External examination during the autopsy revealed that ligature
marks were clear in 11 cases, while the mark was only superficial
in one case (Table 1, case 5). In the latter case, the hanging
occurred when the victim leaned out of a swing-like cradle and a
handmade sash tied around the cradle wrapped around his neck.
Petechial hemorrhages on the facial and or conjunctival tissue were
evident in five cases. All of the cases showed petechial hemor-
rhages at the undersurface of the scalp, and under the pleura and
epicardium. Congestion and edema in the brain and lungs as well
as ecchymosis in the soft tissues under the ligature marks were also
visible in all 12 cases. The hyoid bone and thyroid cartilage did
not fracture in any of the cases. Detailed case information is out-
lined in Tables 1 and 2.
Victims had been removed from the ligatures during the rescue
attempts for all but one of the cases (Table 2, case 1) and had
therefore been moved from the original position before the scene
investigation. However, representations of the victimsoriginal posi-
tions were reenacted by the persons who had found the bodies
(Fig. 3). One victim (Table 1, case 5) died in the hospital from

victims died at the scene of the accident.
Discussion
Although varying in the details, many studies have identified that
the most common causes of accidental death for children are motor
vehicle accidents, drowning, and fires burns (7,8). Accidental
asphyxia can occur in childhood as a result of a variety of common
and rare situations (9).
In a review of 201 hanging death cases, Bowen (4) reported that
5% were accidental. Three of those cases involved infants and in
each case, their clothing had apparently become caught on part of
a crib. Similarly, 13 of the 201 hanging deaths (6.5%) in this study
were accidental, and 12 of the 13 (92.3%) occurred in children.
Our findings demonstrate that accidental hanging cases (in this
region) predominantly occur in children. There are two typical sce-
narios for hanging deaths in children, either accidental hanging in
infancy (in a crib or pram) or accidental hanging at play (usually
involving young boys) (3).
Over a 34-year study period, Byard (9) reported a total of 40 cases
of accidental asphyxia that resulted from unsafe sleeping circum-
stances, including 20 wedging positional asphyxias, 13 hangings, 4
suffocations, and 3 over-layings. Sturner et al. (10) reported 45 cases
of accidental asphyxia deaths involving children, including 11 cases
of wedging. Another study identified broken cribs and pacifier cords
as other causes (11). Accidental asphyxia can occur in younger
children and infants, who may move into positions in which their
airways become occluded, their bodies become wedged so that they
are unable to breathe, or they become suspended from their clothing
or restraining harnesses (1,12–14). Cooke et al. (3) noted three main
causes of crib hangings: entanglement in restraining harnesses, sus-
pension by clothing or pacifier cords, and entrapment against a cribs
structural framework. The study identified seven cases of accidental
asphyxia that resulted from entanglement in restraining harnesses
designed to restrain infants within their cradles.
Many houses in Turkey (especially those situated in the villages
and slums) are built with metal rings mounted in the ceilings, so
that the occupants can set up swing-like cradles, which are ham-
mock-like in nature. The cradles are constructed by tying two ropes
between the two metal rings and connecting them with cloth.
Infants are placed in these cradles on top of cushions, and ligatures
(e.g., scarf, rope, or sash) are tied around the cradles to prevent
them from falling out. However, the ligature can wrap around the
neck and asphyxiate the infant if it leans out of the cradle. Seven
of the accidental hanging cases in this study were caused by this
simple cradle safety mechanism; detailed information about these
cases is given in Table 1.
Cooke et al. (3) reported that a looped curtain cord was the
cause of death of a 1-year-old girl who was found suspended by
her neck near her bed. In another case, a 1-year-old boy was found
suspended by his neck after becoming entangled in a loose electric
heater cable while crawling (Table 2, case 1). A third case involved
a 5 year-old girl found suspended by her neck in a rope-ring lock
on the garden toilets door (Table 2, case 2). Such cases highlight
the potential accidental hanging risk posed by ropes found in or
around the house that are either stretchedortiedtoafixedpoint.
Several more studies are available to reinforce this point. One study
attributed the hanging deaths of three Western Australian boys to
ropes attached to a garden shed, a verandah roof, and a tree (3).
Polson et al. (15) described three cases of accidental hanging
involving children at play; in one case, a 6-year-old boy was play-
ing ‘‘cowboys’’ with a rope and the remaining two involved youn-
ger girls playing with swings. These authors also mention
accidental hanging as a result of boys climbing trees or railings.
Two child hanging deaths were reported by Perrot et al. (16), a
5-year-old boy found suspended from a light fixture in a backyard

medication for attention deficit hyperactivity disorder.

shed and a 6-year-old girl who was suspended from the T bar of a
clothesline. Another study reported the successful resuscitation of a
6-year-old boy after an accidental hanging, which was likely the
result of imitative behavior; the boy had witnessed a ‘‘judicial’’
hanging scene in a television movie (17).
This study identified one case that involved a 7-year-old boy
who was found suspended by a rope that was drooping down from
a wooden door in his houses garden (Table 2, case 3). Two cases
were identified in which boys were imitating climbers they had
seen on television and were hung by a rope when they dropped
down from the roof or the window of their houses (Table 2, cases
4 and 5). The 10-year-old boy was taking medication for attention
deficit hyperactivity disorder (Table 2, case 4).
Accidental and suicidal hanging deaths are predominantly caused
by compression of the blood vessels supplying the brain, where
these (the major veins and the carotid and vertebral arteries) can be
compressed with relatively little force (18). Unconsciousness can
occur very rapidly, causing the body to become limp and intensify-
ing compression of the blood vessels. The presence of a ligature is
not necessary to classify such a death as hanging, provided that
constriction of the neck as a result of the victims body weight can
be demonstrated (5).

Hanging deaths are readily identifiable at autopsy by the ligature
marks around the neck and occasionally by facial petechiae. Liga-
ture marks were clear in 11 of the 12 autopsy cases in this study
(Table 1, case 5). The ligature marks were superficial in the 12th
case, which was caused by a sash tied around a cradle. Petechial
hemorrhages on the f ace and or conjunctivae were evident in five
cases, but were present at the undersurface of the scalp, as well as
under the pleura and the epicardium in all of the cases. Macro-
scopic and microscopic hemorrhages were seen in the soft tissues
localized under the ligature marks. All cases also had congestion
and edema of the brain and the lungs, but the hyoid bone and thy-
roid cartilage were not fractured in any of the cases, which was
likely due to the elasticity of these structures in children.
Scene investigation is very important in accidental hanging cases,
as the causal factors can be identified by examining the scenes of
death. Beyond their importance in determining the cause of death,
the causal factors may have direct implications for public health
policy and legislation (9,19). However, when the victims in our
study were found suspended, they were immediately removed from
their ligatures and taken to local hospitals for resuscitation. As a
result, all but one of the victims (Table 2, case 1) were not in their
original positions during the scene investigation. In these situations,
the circumstances of the case are generally explained by examining
the hanging mechanism and having the persons who found the sus-
pended victims recreate their original positions.
Although it is not possible to predict every dangerous circum-
stance, knowing a range of causes may enable us to make certain
generalizations regarding child safety (20). Swing-like cradles are
predominantlyusedbypoorandor uneducated families in Turkey.
When asked by the Public Prosecutor if the victimsdeaths were
the result of parental negligence, the Forensic Medicine Expert
often believed (in the cases of swing-like cradles) that the parents
were unaware, due to poor education, that the ligatures they used
to keep their infants in their cradles could cause the infantsdeaths.
Educating families on the risks of rope-suspended cradles could
prevent future accidental hanging cases.
In conclusion, the number of childhood accidental hanging
deaths can be reduced by replacing swing-like cradles with beds
that are designed for children, removing ropes in and around the
house in which children might get entangled, and preventing chil-
dren from reaching and or playing with rope-like objects.

... Suicide, which is among the top 10 causes of death worldwide, occurs in different forms in different countries depending on cultural, economic, and social conditions. 1 In Bahrain, Japan, Thailand, most European countries, and Turkey, hanging is the primary method of suicide. 1 Accidental hangings are infrequent and represent approximately 2%-6.5% of all hanging cases. [2][3][4][5] Cases of homicidal hangings are extremely rare and represent 1.6% of all hanging cases. 6,7 In a study on the death penalty, which has been abolished or is not applied in many countries today, it was seen that 36 methods have been defined throughout history, the foremost of which was reported to be hanging. ...

The aim of this review was to investigate the types and rates of vascular lesions occurring in cases of completed hanging and near-hanging, defined in literature. In the literature to date, 6 specific types of vascular injuries have been defined in cases of death as a result of hanging. These are Amussat's sign, Etienne Martin's sign, Dominguez-Paez sign, Friedberg-Lesser sign, Ziemke-Otto's sign, and Lupascu sign. As a result of this study, it was determined that the most defined finding was the Amussat sign, and it was concluded that the other findings were not sufficiently recognized. Likewise, considering that the proportional differences are due to the differences in the rates of autopsy practice and autopsy protocols between countries, it can be suggested that international joint autopsy protocols should be developed at the meetings in which national professional associations participate.

A comprehensive review of medical examiner data was undertaken of all hanging deaths in the Canadian Maritime province of Newfoundland and Labrador from 1982 to 2021. A total of 811 cases were identified representing suicidal, accidental, and undetermined manners of death. Variables examined included age; sex; seasonality; ligature type; location; time since death; prior attempts/suicidal ideation; presence/absence of a suicide note; and presence/absence of alcohol and drugs. Data subsets were generated, and additional analysis was conducted for hangings involving females; suicidal hangings occurring in the region of Labrador; and those who hanged themselves outdoors. Results indicate that females are choosing to kill themselves by hanging in rapidly increasing numbers. Outdoor suicides by hanging were more common in Newfoundland and Labrador (22.1%) than previously reported in Alberta (11.5%), Texas (5%), and Turkey (12–13%). Unique trends in seasonality were revealed, as were repeated incidents of suicidal clusters. The age distribution was skewed strongly toward youths (10 to 22 years of age), particularly in Labrador. Although Labrador represents only 5% of the total provincial population, it produced 20.1% of the total suicidal hangings in the study. The suicide rate in Canada has decreased by 24% over the past 40 years, yet the rates of suicidal hangings nationally and in Newfoundland and Labrador have increased during the same time period. With a better understanding of the circumstances under which people commit suicide by hanging within the province, it may be possible to target at‐risk groups to prevent future cases.

ABSTRACT The tooth can be saved with routine root canal treatment in which pulp tissue is irreversibly damaged or necrotic. Although current treatment modalities offer high levels of success for many conditions, an ideal treatment approach is regenerative configurations include forming healthy pulp tissue by providing a natural extracellular matrix mimicking environment; stem cells, signaling molecules, and scaffolds after the damaged, infected, or necrotic tissue is removed. Current endodontic regeneration includes disinfection of the root canal using chemicals and irritating the root apex tissue to form a blood clot inside the root canal to act as a natural scaffold and support pulp-dentin stem cell proliferation and differentiation. Besides, host-derived scaffold structures containing growth factors are also used in endodontic regeneration practice (platelet-rich plasma, platelet-rich fibrin, etc.). However, recent studies reported that the regenerated tissues from this management are mainly a dentin-like structure, cementum-like, and bone-like periodontal tissues instead of pulp-like tissue. It has been stated that the transport of nanostructured and functionalized carriers into the damaged area by the method of encapsulation that includes signaling molecules, also known as a "targeted release system", may contribute to pulp-like regeneration. With recent technology, these materials are obtained synthetically and biologically. The purpose of this review is to present a comprehensive presentation of the current and potential applications, benefits, future expectations, and challenges of encapsulation as a nanotechnology application in the field of endodontics. The review was conducted by searching the relevant articles from the databases using appropriate keywords. As a result, although nanobiomaterials and nanotechnology are limited in regenerative endodontics, studies and rapidly developing technology show that these applications promise to replace the target lost tissue. Time, new developments, economic/technical resources, and human needs will determine which applications will be carried out first.

Pulpası geri dönüşümsüz olarak hasara uğramış veya nekroze olmuş dişler rutin kök kanal tedavileri ile kurtarılabilir. Mevcut tedavi modaliteleri birçok durum için yüksek başarı seviyeleri sunsa da ideal bir tedavi yaklaşımı, hasarlı, enfekte ya da nekrotik dokunun uzaklaştırılmasından sonra yerine sağlıklı pulpa dokusunu kök hücreler, sinyal molekülleri ve yapı iskeleleri ile taklit eden doğal bir hücre dışı matris oluşturulacağı rejeneratif yapılandırmalardır. Mevcut endodontik rejenerasyon prosedürleri, kimyasallar kullanarak kök kanalının dezenfekte edilmesini ve apikal bölgede oluşturulan bir iritasyonla kök kanalını dolduran kan pıhtısının doğal bir iskele görevi görmesi ile pulpa-dentin kök hücre çoğalmasını ve farklılaşmasını desteklemeyi amaçlar. Bu amaçla, büyüme faktörlerini içeren hasta kaynaklı (plateletten zengin plazma, plateletten zengin fibrin, vb.) iskele yapıları da endodontik rejenerasyon uygulamasında kullanılmaktadır. Ancak, son çalışmalar, bu yöntemlerin pulpa benzeri doku yerine dentin benzeri, sement benzeri ve kemik benzeri periodontal dokuları rejenere ettiğini bildirmiştir. Sinyalci molekül içeren enkapsülasyon bir diğer ismi ile “hedefli salınım sistemi” olan yöntem ile nanoyapılı ve işlevselleştirilmiş taşıyıcıların hasarlı bölgede kullanılmasının pulpa benzeri doku rejenerasyonuna katkısı olabileceği ifade edilmiştir. Günümüz teknolojisi ile bu materyaller sentetik olarak ve biyolojik olarak elde edilmektedir. Bu derlemenin amacı nanoteknoloji uygulamalarından enkapsülasyonun endodonti alanında mevcut ve potansiyel uygulama, fayda, gelecek beklenti ve zorluklarının kapsamlı bir şekilde sunulmasını amaçlamaktadır. Araştırma uygun anahtar kelimeler kullanılarak veritabanlarından ilgili makalelerin incelenmesiyle yapılmıştır. Sonuç olarak, rejeneratif endodonti alanında nanobiyomalzemeler ve nanoteknolojinin kullanımı sınırlı olsa da üzerinde yapılan çalışmalar ve hızla gelişen teknoloji, bu uygulamalarının türetilmek istenen hedef dokuların yerine konmasında umut vaadettiğini göstermektedir. Zaman, yeni gelişmeler, ekonomik/teknik kaynaklar ve insan ihtiyaçları, hangi uygulamaların öne geçeceğini belirleyecektir.

Objective: Hyperparathyroidism increases systemic inflammation directly or indirectly as a result of abnormal calcium and phosphate mechanisms. However, the effect of parathyroidectomy on inflammation remains uncertain. In this study, it was aimed to analyze the relationship between curative parathyroidectomy and systemic inflammation response in patients with primary hyperparathyroidism with simple inflammatory parameters. Method: The prospectively recorded data of patients who underwent surgery for primary hyperparathyroidism between July 2008 and July 2019 were retrospectively analyzed. Patients who developed persistent hyperparathyroidism and those with missing follow-up data were excluded from the study. Demographic characteristics (age and gender), adenoma size, preoperative and 6th month after parathyroidectomy calcium (Ca), parathyroid hormone (PTH), hemoglobin (Hb), thrombocyte, lymphocyte and neutrophil levels were recorded. Pre and postoperative neutrophil / lymphocyte ratio (NLR) and thrombocyte / lymphocyte ratio (TLO) were calculated. Hb, NLR and TLO measurements before and after parathyrodectomy were compared to evaluate the systemic inflammation response. Results: Thirty-seven (27.2%) of 136 patients in the study were male and 99 (72.8%) were female. The mean age was 53.47 ± 12.42 years and the mean diameter of adenoma was 1.98 ± 0.92 cm. Preoperative Ca value of the patients was 11.18 ± 0.79 mg/dL, while postoperative Ca mean was 9.51 ± 0.85 mg/dL. Preoperative PTH was 290.81 ± 329.63 pg/mL while postoperative PTH mean was 23.57 ± 20.93 pg/mL. Preoperative Hb was measured as 13.26 ± 1.56 g/dL and postoperative Hb was measured as 13.53 ± 1.57 g/dL. The mean preoperative NLR was 2.91 ± 2.96, while postoperative 2.24 ± 1.73. The mean preoperative TLO was 141.73 ± 61.16, while it was 135.14 ± 68.70 postoperatively. It was observed that there was a significant difference between the measurements of inflammatory markers Hb, NLR and TLO before and after parathyroidectomy (p = 0.003, p = 0.011, p = 0.027, respectively). Conclusion: Curative parathyroidectomy provides significant regression in systemic inflammation in patients with primary hyperparathyroidism. Detailed examination of this result may reinforce the importance of parathyroidectomy in particular patient groups more prone to the adverse effects of chronic inflammation.

Young children are at risk of head entrapment because they often do not understand potentially dangerous situations or have the intellectual or physical capabilities to self-extricate. Two cases of head entrapment due to hinged lids are presented to demonstrate another rare lethal situation specific to the very young. Case 1 was a 14-month-old boy found suspended by his neck in a semikneeling position under a toilet seat. A horizontal linear bruise measuring 0.6 × 20 mm was present on the right side of the neck with petechial hemorrhages of the forehead. Death was due to neck compression from head entrapment with aspiration of gastric contents. Case 2 was a 17-month-old girl found suspended by her neck from the side of her crib by a hinged cover. A horizontal linear bruise measuring 10 × 50 mm was present immediately below the suprasternal notch with numerous petechial hemorrhages of the conjunctivae and face. Death was due to neck compression from head entrapment. Although these cases are very rare, they do show the potential danger that hinged lids may present to toddlers. Autopsy evaluations require comparisons of injuries with the structure and edges of the entrapping device/object.

Türkiye’de tıp eğitimi gerçek anlamda ilk kez 14 Mart 1827 tarihinde Vezneciler’de Tulumbacıbaşı Konağında Tıphane” adıyla kurulan okulda başlar. 1839’da “Mekteb-i Tıbbiye-i Adliye-i Şâhâne” adını alan okulda; Avusturya’dan gelen Dr. Charles Ambroise Bernard ilk kez adli tıp derslerini 1841’de “ Tıbb-i Kanuni” adı ile vermeye başlar ve ilk otopsi de başına sırık düşerek ölen bir işçinin cesedine uygulanır. Aradan bunca yıl geçmiş olmasına rağmen, bugün ülkemizde “adli tıp” olması gereken yerde midir? Bu soruya, “evet” yanıtı vermemiz ne yazık ki olanaksızdır. Tüm dünyada “adli tıp” ve daha genel bir ifade ile “adli bilimler” günümüzde bilim ve teknolojideki ilerlemelerle birlikte, birçok adli, tıbbi ve sosyal olayın aydınlatılmasında önemli bir konum kazanmıştır. İletişim ve teknoloji çağına dönüşen 21.yüzyıl adli tıbbı, sosyal, popüler ve bir o kadar da medyatik hale getirmiştir. Türkiye’de evrensel örneklerin dışında, adli tıbbın uygulamaları tek bir merkezi yapı olan Adli Tıp Kurumu bünyesinde yürütülmekte; üniversiteler büyük ölçüde bu uygulamaların dışında kalmaktadır. Adli tıbbın ülkemizdeki mevcut bu sistemi başlı başına devasa bir sorundur. Adli tıp ve adli bilimler alanında; öğrenci, asistan ve uzmanların eğitimi, bilginin elde edilmesi ve paylaşımı, materyalden yararlanma ve rutin uygulamalara katılımda ciddi problemler bulunmaktadır. Bu durum, doğallıkla bilimsel araştırmaların yapılması; bilginin toplumda üretilmesi, yayılması ve kullanımı açısından da önemli bir engel oluşturmaktadır. Öte yandan, görevi ve uzmanlığı ne olursa olsun, tüm hekimler meslek yaşamında adli tıp konularıyla hemen her gün karşılaşmaktadırlar. Mesleki olarak adli tıp konularında kendilerini geliştirmek, güncel bilgi ve uygulamalara ayak uydurmak durumundadırlar. İşte bu ortak çalışma, yalnızca adli tıp asistan ve uzmanlarına değil; adli tıp konuları ile karşılaşan tüm hekimlere ve hatta tıp öğrencilerine yardımcı olmak üzere hazırlandı. Toplumda her gün adli tıp ile ilgili sorunların artması ve adli tıbbın kimi zaman olumsuz da olsa hep gündemde kalması nedeni ile, bu tür bilimsel kaynaklara neden gereksinim duyulduğu aşikârdır. İstanbul Tabip Odası Yönetim Kurulu ve Klinik Gelişim Dergisi Yayın Kurulu’na; Adli Tıp özel sayısı çıkarılmasına destekleri için teşekkür ederiz. Klinik Gelişim Dergisi’nin bu özel sayısının hazırlanma sürecinde; adli tıp açısından “kitap formatı” niteliğinde, kapsamlı bir başvuru kaynağına dönüştüğünü gördük. Bu çalışma aynı zamanda, bizde adli tıbbın temel konularını içeren kitap ve benzeri çalışmalar arasında, “yerinde kaynak gösterme” yöntemi ile hazırlanmış, “derleme” türü, ilk kapsamlı çalışma özelliği de taşımaktadır. Bununla birlikte, konu başlığı seçimi ve içeriklerinde, derginin amacı ve hacmi dışına taşan bilimsel ayrıntılardan bilinçli olarak kaçınmaya çalıştık. Öte yandan bu ortak çalışmada, birçok meslektaşımızın, özellikle süre kısıtlılığı nedeni ile “yazar” olarak yer alamadığını üzülerek belirtmek zorundayız; anlayışla karşılanacağını umuyoruz. Tüm hekimlerin adli tıp konuları ile “hiç karşılaşmamasını” dileyemesek; “nadiren karşılaşmasını” dilesek de, bu çalışma şayet, hekimlerin gerek duyduklarında yararlanabilecekleri bir kaynak olabilecek ise, mutluluk duyarız. Saygı ve dostlukla… Mart 2009 Dr. Sermet KOÇ Dr. Muhammet CAN

Sixteen accidental deaths of infants occurred in Wayne County (Detroit) during 1974-1975 as a result of unsafe sleeping environments. Thirteen of these deaths resulted from different modes of asphyxia, two were due to falls, and one drowned. Differential diagnoses are pointed out. It is estimated that over 600 infants die each year in the United States due to unsafe sleeping conditions. Despite the magnitude and importance of this problem, little has been provided to the public in the form of preventive education. Federal regulations, passed in 1974, control the manufacture of new cribs but do not affect the existing unsafe cribs. Suggestions for the prevention of such fatal accidents are outlined, in cluding a safety check list for infant beds. The cooperation of all health professionals is required to educate the public of these dangers to their infants.

Forty-five cases of accidental asphyxial deaths in infants and young children below 2 years of age are described. The mechanism involved, the available historical information, and the possible preventive measures are discussed. Dangers such as bed- and tub-sharing, diaper and cleaning pails, plastic wrappers, balloons, small beds, toys on strings, broken or poorly designed cribs, and poorly positioned adult beds must be brought to the attention of the parent as consumer. The public heatlh considerations and the educational aspects relating to the community at large are cornerstones in the effort to reduce these tragic and untimely deaths.

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as a result of strangulation. Three deaths were due to overlying. Three other infants had been placed on sheepskin rugs for the first time and were found dead shortly thereafter. These infants ranged in age from 2 to 9 months, except for a severely mentally retarded nine-year-old with spastic paraplegia. We believe that a general warning should be issued concerning water beds and that soft bedding should not be used for infants. Infants should not be placed unattended or left to sleep on water beds; only beds recommended for infants should be used. Overlying of a young infant is most likely to occur on a water bed, or if the parent is obese or has consumed alcohol.

Trauma is the leading cause of death for children over 1 year of age. This study was undertaken to identify the patterns of injury among children admitted to a regional pediatric trauma center. During a 34-month period, 3,472 injured children were consecutively admitted to a regional pediatric trauma center. Data were collected on medical, etiological, and financial aspects of injury. Eight subgroups were defined by mechanism of injury: motor-vehicle crash occupants, pedestrian and cycle injuries, falls, child abuse, gunshot and stab wounds, burns, poisonings, and foreign body ingestions or aspirations. Analysis of variance, Duncan's multiple range test, and contingency table analysis were used to determine differences among subgroups of children. Blunt and penetrating trauma accounted for 64.3% of all admissions. The mean age of injured children was 5.5 years; 64% of the children were boys. Sixty-seven percent of the children were admitted directly from the scene of injury. One-way analysis of variance yielded significant differences in mean age, mean hospital length of stay (LOS), mean intensive care LOS, mean trauma score, mean injury severity, and mean hospital charges by mechanism of injury (P less than .01). The overall mortality rate was 2.4%. Child abuse, gunshot/stab wounds, and drowning had the highest mortality rates, but injuries to motor-vehicle crash occupants and pedestrians accounted for the greatest number of deaths.

During the 16-year period of 1972-1987, there were 11 hanging deaths in children in Western Australia. We report the circumstances and medical findings of each case.

Fifty-six consecutive cases of suicide by hanging are reviewed. The data provide some evidence for associations between suicide by hanging and youth, incarceration, black males, and clustering. Evidence was noted of low incidence in females, rarity of white female hangings at home, a preference to hang oneself away from home if there have been previous suicide attempts, and possible seasonal trends which may differ from suicide overall. Thus, aside from the method chosen, hanging victims as a group displayed some differences from suicides in general.
Article
Correlation of the circumstances of death with the pathologic findings in this prospective study of deaths by hanging affords insight pertaining to certain of the pathophysiologic mechanisms involved in fatalities of this type. The presence of conjunctival and facial/periorbital petechial hemorrhages correlates with increasing levels of body support below the point of ligature suspension. Hyoid bone and/or thyroid cartilage fractures (found in 26% of cases) are most frequently identified in those persons found completely suspended and in victims in the older age ranges. No hyoid bone/thyroid cartilage fractures, internal soft tissue injury, or petechiae were present in 13 (21%) of the study cases.
