Meconium aspiration syndrome (MAS) frequently occurs in neonates born in thick meconium-stained liquor (TMSL). It continues to be a significant cause of neonatal morbidity and mortality despite aggressive approaches to intervention. This study aims to identify the perinatal characteristics of deliveries with TMSL associated with the development of MAS and to describe the outcome of those babies who developed MAS.
All newborns with TMSL born in Hospital Alor Setar, Kedah from 1 October 1998 to 30 April 1999 were prospectively studied. In the hospital, all newborns with TMSL were routinely admitted to the Special Care Nursery for observation. Relevant data regarding pregnancy, delivery, resuscitation and outcome of newborns with and without MAS were collected and analysed. The incidence of TMSL among hospital deliveries was 2.2% (95% C.I. 1.8-2.5%). Thirty-six percent (95% C.I. 28.4-44.7%) of newborns with TMSL developed MAS. Significant risk factors associated with the development of MAS were non-Malay mothers (p=0.04, OR=3.32), resuscitation by paediatric medical officers (p=0.02, OR=2.84) and direct tracheal suction during resuscitation (p=0.02, OR=2.61). The presence of non-Malay mothers or resuscitation by paediatric medical officers or direct tracheal suction during resuscitation gave a sensitivity of 88.2%, specificity of 36.7%, a positive predictive value of 44.1% and a negative predictive value of 84.6% for the development of MAS. Asphyxia, pneumothorax and persistent pulmonary hyper-tension occurred in 25.5%, 7.8% and 5.9% of the babies with MAS respectively. Mechanical ventilation was required in 51% and the mortality rate was 3.9%. In conclusion, the incidence of TMSL and MAS and the mortality rate of neonates with MAS were comparable with that in developed countries. The presence of any one of the significant risk factors had high sensitivity but low specificity for the development of MAS. Newborns were unlikely to develop MAS if all these risk factors were absent.

This article highlights methods of ending life in different ethnic groups. This inference is drawn from analysis of data from suicidal cases from the University Malaya Medical Centre mortuary. This study also looked at sex, age, social, and employment factors. Kuala Lumpur has sizeable populations of Muslims, Chinese, Indians and Indonesian, etc. This study is based on 251 cases of suicide that were reported at the University Malaya Medical Centre from 2000 to 2004. Malaysia has a population of 22,662,365 people with 3 major ethnic groups: Malay (58%), Chinese (24%), and Indians (8%) with a minority of "others" (10%), which includes foreigners, Sabahan, and Sarawakian. This research found suicides of 164 male (65%) and 87 female (35%) victims. Their age ranged from 15 to 80 years. The age group from 21 to 30 had the highest total cases of suicide (83 of 251; 33.1%). Among ethnic groups highest rate of suicide was among Chinese with a total of 120 cases (120 of 251; 47.8%). As far as lone method of suicide is concerned, hangings accounted for the highest proportion of cases (108 of 251; 43%). Among ethnic groups, jumping from height was the commonest method used by Chinese (49 of 120; 41%), Malay (9 of 16; 56%), and others (15 of 28; 53.4%); whereas, hanging was the commonest method of committing suicide by Indians (49 of 87); Muslims showed the lowest cases of suicide (18 of 251; 7.2%). In poisoning group Indian was the highest ethnic group who used this method (20 of 37; 54.1%).

Suicide patterns in children and adolescents: a review from a pediatric institution in England

Zainum K, Cohen MC

Forensic Sci Med Pathol, 2017 Jun;13(2):115-122.
PMID: 28349246 DOI: 10.1007/s12024-017-9860-y

Suicide is a catastrophic event to both families and communities yet it is potentially preventable. This study aims to determine incidence and patterns of suicide in children and young adolescents in our region, raise awareness of this entity as a potentially preventable cause of death in this age group, and identify its possible associated risk factors. We retrospectively reviewed suicide cases presenting as sudden unexpected death in children and adolescents that underwent coronial post-mortems at our institution. This is the largest pathological review of completed suicide in children and young adolescents within a single institution in the United Kingdom. We identified 23 suicide cases during a 12 year period from 2003 to 2015, in which 18 cases (78%) were male and 5 cases (22%) were female. The age range was from 8 to 16 years (mean age 12.82 +/- 2.52 SD). With the exception of one case, all of the victims were Caucasian. The majority, 19 cases (81%), were found dead inside their place of residence, 15 of whom were discovered in their own bedrooms. Twenty-one cases (91%) died from neck compression due to hanging; 6 cases (26%) had used the cord of a dressing gown and 5 (22%) opted to use a belt as the ligature. Two cases (9%) that died from multiple-drug toxicity were female. In 7 cases (30.5%) there was evidence of self-harm and in 3 cases (13%) there was a history of previous suicide attempts. Petechial hemorrhages were found at autopsy in more than half of hanging victims and only three cases (14%) displayed dual distribution of post-mortem hypostasis (back and legs). Seven victims (30.5%) left some form of suicide message to family members and friends, 2 of which wrote the message on their arm. Parental separation, conflict with parents, and depression, were common amongst decedents prior to committing suicide. Substance abuse was uncommon in suicide within our cases. Valuable information is available from thorough review of suicide data in children and young adolescents from a single institution. Pathologists and clinicians can play crucial roles in identifying potential risk factors that may contribute to prevent future deaths.

Dinoflagellate bloom in tropical fish ponds of coastal waters of the South China Sea

Shamsudin L, Awang A, Ambak A, Ibrahim S

Environ Monit Assess, 1996 May;40(3):303-11.
PMID: 24198160 DOI: 10.1007/BF00398875

Red tide of dinoflagellate was observed in brackish water fish ponds of Terengganu along the coast of the South China Sea during the study period between January 1992 to December 1992. The nearby coastal moat water facing the South China Sea is the source of water for fish pond culture activities of sea bass during the study period. An examination of water quality in fish ponds during the study period indicated that both the organic nutrients were high during the pre-wet monsoon period. The source of the nutrients in coastal water was believed to be derived from the agro-based industrial effluents, fertilizers from paddy fields and untreated animal wastes. This coincided with the peak production of dinoflagellate in the water column in October 1992. The cell count ranges from 8.3 to 60.4×10.4×10(4)/l during the bloom peak period and the bloom species were compared entirely of non-toxic dinoflagellates with Protoperidinium quinquecorne occurring >90% of the total cell count. However, both cultured and indigenous fish species were seen to suffer from oxygen asphyxiation (suffocation due to lack of oxygen). The bloom lasted for a short period (4-5 days) with a massive cell collapse from subsurface to bottom water on the sixth day. The productivity values ranged from 5-25 C g/ l / h with a subsurface maximum value in October 1992. Two species of Ciliophora, Tintinnopsis and Favella, were observed to graze on these dinoflagellates at the end of the bloom period.

Fulltext Understanding the decision-delivery interval in cesarean births

Naseem, Rashid, Nalliah, Sivalingam

International e-Journal of Science, Medicine & Education, 2007;1(2):61-68.
MyJurnal

Avoiding the adverse neonatal effects of perinatal asphyxia has been one of the common indications for cesarean deliveries in current obstetric practice. Expeditious delivery is dependent on decision to perform cesarean delivery and time lines achieved. A decision-delivery interval of 30 minutes, a concept initiated by the American College of Obstetricians and Gynecologists has open to debate as controversy reins about neonatal outcome when this time interval is considered in isolation. Time lines alone are probably not the only criteria to be employed, and may contribute to errors in interpretation by professional regulatory bodies and the society at large. Procedures prior to decision making like trial of labour, fetal scalp sampling and readily available resources for instituting emergent cesarean delivery invariably need to be considered. Though decision to delivery time is an integral component of critical conduct intervals in the acutely compromised fetus, a more pragmatic approach needs to be taken considering potential and known logistical and obstetric factors in line with good obstetric practice.

Malaysian Journal of Child Health, 1993;5(1):9-19.
MyJurnal

An analysis of perinatal statistics in Peninsular Malaysia from 1980 — 1989 was undertaken. The Perinatal Mortality Rate showed a 42% decrease over the 10 year period. The Perinatal Mortality Rate was higher among the Indian and Malay ethnic groups compared to the Chinese. This was largely contributed by the higher Stillbirth rate in the former 2 ethnic groups. The Indians have the highest rate of low birthweight babies. There is a decline in the rate of low birthweight babies born over the studied decade. The major causes of early neonatal mortality included problems asociated with prematurity, asphyxia neonatorum, septicaemia and congenital anomalies. Further epi-demiological research is required to identify other riskfactors which contribute to this ethnic biased perinatal mortality rates. Besides intensifying and upgrading current multifaceted approaches, interventional strategies need to be directed to the identified high risk groups. (Copied from article).

Planned complex suicide: self-strangulation and fall from height

Nor FM, Das S

J Forensic Leg Med, 2011 Oct;18(7):336-9.
PMID: 21907941 DOI: 10.1016/j.jflm.2011.06.013

We hereby present a case of planned complex suicide. In this case study, we report a teen-aged girl who committed suicide by strangulating herself, and subsequently fell from the 13th floor of a housing apartment. The planned complex suicide was substantiated by the presence of a suicide note and a photograph captured in a mobile handset. To the best of our knowledge, it is the first case involving self-strangulation and fall from height, in which the photograph was stored in the handset. This is to further emphasize that objects like mobile handsets can be important in determining the cause and manner of death. The available evidence at the site of incident should be explored meticulously in order to arrive at a proper conclusion.

Factors associated with clinically significant perinatal asphyxia in the Malaysian neonates: a case-control study

Boo NY, Lye MS

J Trop Pediatr, 1992 12;38(6):284-9.
PMID: 1844086 DOI: 10.1093/tropej/38.6.284

A 2-month prospective study was carried out in a Kuala Lumpur maternity hospital to determine the antenatal and intrapartum factors associated with perinatal asphyxia in the Malaysian neonates. The incidence of perinatal asphyxia was 18.7 per 1000 livebirths. Of the 75 asphyxiated neonates born during this period, 70 (93.3 per cent) were of term or post-term gestation. The incidence of perinatal asphyxia was more common in the neonates with one of the following characteristics: low birth weight (< 2500 g), breech delivery, or delivery by instrumentation or lower segment Caesarean section (P < 0.001). Conditional logistic regression analysis of the asphyxiated and the control neonates in a nested case-control study (after controlling for sex, race, birth weight, modes of delivery, and maternal gravida) showed that there were two associated factors which were of statistical significance. These were: small-for-gestation neonates and the presence of intrapartum problems. Our study suggests that to reduce the incidence of perinatal asphyxia, the common causes of small-for-gestation neonates and the common types of intrapartum problems should be identified to enable appropriate preventive measures to be carried out.

PMID: 33612780 DOI: 10.47665/tb.37.3.663

Third-generation cephalosporin resistant Enterobacteriaceae (TCRE) is a global concern especially in neonatal sepsis. We performed a secondary data analysis in a Thai neonatal intensive care unit to identify the risk factors for acquisition of TCRE sepsis and mortality of Enterobacteriaceae sepsis between 1991 and 2017. Multivariate logistic and Cox proportional regression were used for analysis. Numbers of neonates with TCRE and nonTCRE sepsis were 100 and 41 patients, respectively. Medians (interquartile ranges) of gestational age, birthweight, onset of sepsis and total hospital stay of neonates with Enterobacteriaceae sepsis were 32 (28, 38) weeks, 1670 (1025, 2750) grams, 11 (6, 25) days and 41 (22, 74) days, respectively. Univariate and multivariate analysis, neonates with TCRE sepsis were more likely to have birth asphyxia (adjusted odds ratio [aOR] = 2.6; 95% confidence interval [CI] 1.1-6.0; p = 0.02) and history of aminoglycoside exposure (aOR = 2.9; 95% CI 1.3- 6.7; p = 0.01). In-hospital case fatality rate from Enterobacteriaceae sepsis was 26% (36/141). In Cox regression, neonates with TCRE sepsis was not an independent risk of non-survivors, but septic shock (adjusted hazard ratio = 9.9; 95% CI 5.0-19.7, p < 0.001) increased 30-day mortality in the final model. Asphyxia and previous aminoglycoside consumption were risks of acquisition for neonatal TCRE sepsis while the burden was not a significant difference. Infection prevention and control must be strictly implemented in high multidrug-resistant area.

Hariharan M, Sindhu R, Vijean V, Yazid H, Nadarajaw T, Yaacob S, et al.

Comput Methods Programs Biomed, 2018 Mar;155:39-51.
PMID: 29512503 DOI: 10.1016/j.cmpb.2017.11.021

BACKGROUND AND OBJECTIVE: Infant cry signal carries several levels of information about the reason for crying (hunger, pain, sleepiness and discomfort) or the pathological status (asphyxia, deaf, jaundice, premature condition and autism, etc.) of an infant and therefore suited for early diagnosis. In this work, combination of wavelet packet based features and Improved Binary Dragonfly Optimization based feature selection method was proposed to classify the different types of infant cry signals.
METHODS: Cry signals from 2 different databases were utilized. First database contains 507 cry samples of normal (N), 340 cry samples of asphyxia (A), 879 cry samples of deaf (D), 350 cry samples of hungry (H) and 192 cry samples of pain (P). Second database contains 513 cry samples of jaundice (J), 531 samples of premature (Prem) and 45 samples of normal (N). Wavelet packet transform based energy and non-linear entropies (496 features), Linear Predictive Coding (LPC) based cepstral features (56 features), Mel-frequency Cepstral Coefficients (MFCCs) were extracted (16 features). The combined feature set consists of 568 features. To overcome the curse of dimensionality issue, improved binary dragonfly optimization algorithm (IBDFO) was proposed to select the most salient attributes or features. Finally, Extreme Learning Machine (ELM) kernel classifier was used to classify the different types of infant cry signals using all the features and highly informative features as well.
RESULTS: Several experiments of two-class and multi-class classification of cry signals were conducted. In binary or two-class experiments, maximum accuracy of 90.18% for H Vs P, 100% for A Vs N, 100% for D Vs N and 97.61% J Vs Prem was achieved using the features selected (only 204 features out of 568) by IBDFO. For the classification of multiple cry signals (multi-class problem), the selected features could differentiate between three classes (N, A & D) with the accuracy of 100% and seven classes with the accuracy of 97.62%.
CONCLUSION: The experimental results indicated that the proposed combination of feature extraction and selection method offers suitable classification accuracy and may be employed to detect the subtle changes in the cry signals.

A post-dated intra-uterine growth retarded male Malay baby was born to a 30-year-old mother gravida II by Caesarean section. Her previous pregnancy ended in still-birth. The baby was severely asphyxiated at birth. He was intubated and immediately admitted to the neonatal intensive care unit. He had anasarca, anaemia, purpura and firm, massive hepatosplenomegaly. X-rays revealed ascites and bilateral metaphysiitis of the long bones. The haemoglobin level was 5.0 gm/dl and PCV 18.3%. Coombs' test was negative. Prothrombin time (PT) and partial thromboplastin time (PTT) were prolonged. The baby and mother were positive for Venereal Disease Research Laboratory (VDRL) and the treponema pallidum haemagglutination assay (TPHA) tests. The baby was actively resuscitated but expired at three and a half hours of life due to overwhelming sepsis associated with severe anaemia and disseminated intravascular coagulation.

Environ Monit Assess, 1991 Oct;19(1-3):287-94.
PMID: 24233946 DOI: 10.1007/BF00401318

Increased primary plankton productivity was observed in a brackish water lagoon of Terengganu during the study period between January 1988 to December 1988. The lagoon is also the site for the fish cage culture activities of sea bass during the study period. An examination of water quality at the sampling stations during the study period indicated that both the organic and inorganic nutrients were high during the pre-monsoon period. The source of the nutrient in the lagoon was believed to be derived from the agro-based industrial effluents, fertilisers from paddy fields as well as untreated human and animal wastes. This coincided with the peak production of plankton in the surface waters of the brackish water lagoon. During this period both cultured and indigenous fish species were seen to suffer from oxygen asphyxiation (suffocation due to lack of oxygen). The primary productivity values ranged from 9 to 22 μg/L/h during the peak period while the microplankton species were composed of diatom, flagellates and dinoflagellates. Reduction in the primary productivity values were obtained with reduction in sallinity, specially during the peak monsoon months (November to March) corresponding to the Northeast monsoon period.

Choking on food: a rare case of alexander leukodystrophy and choking

Murty OP, Mun K, Gopinath N, Wong KT

Am J Forensic Med Pathol, 2008 Dec;29(4):364-7.
PMID: 19259028 DOI: 10.1097/PAF.0b013e3181859ff7

Every body has to eat to survive but it becomes a matter of great concern, when the life provider food becomes an asphyxiating agent. In this case, a 60-year-old woman choked herself while swallowing biscuits. On autopsy examination, biscuits were found lodged in larygo-pharynx. Brain showed marked dystrophy and loosened lusterless white matter. On histopathologic examination, brain tissue had numerous eosinophilic globules representing astrocytic processes called "Rosenthal fibers"; hence, it was diagnosed as a case of Alexander dystrophy. It is a disease of white matter, where there is a progressive degeneration of the white matter of the brain because of imperfect growth or development of the myelin sheath. The histopathology of brain showed Rosenthal fibers in abundance. This is one of the rarest disease in which choking can occur because of lack of nervous and muscular coordination and weakness. Its specific relation to choking is documented in this report.

Various complications are associated with the use of indwelling voice prostheses. We present problems faced by a patient with his Voice-Master prosthesis, the ingestion of the prosthesis followed by a potentially fatal aspiration. The Voice-Master is unique in that in can be re-inserted. The safety strap is removed after primary insertion once the prosthesis is secure. However, during re-insertions this safety mechanism is no longer present. Therefore we recommend the placement of a temporary stitch or tie to minimize the risks of ingestion or aspiration of the prosthesis during re-insertions.

Infant asphyxia is a condition due to insufficient oxygen intake suffered by newborn babies. A 4 to 9 million occurrences of infant asphyxia are reported each year by WHO. Early diagnosis of asphyxia is important to avoid complications such as damage to the brain, organ and tissue that could lead to fatality. This is possible with the automation of screening of infant asphyxia. Here, a non-invasive Asphyxia Screening Kit is developed. It is a Graphical User Interface that automatically detects asphyxia in infants from early birth to 6 months from their cries and displays the outcome of analysis. It is built with Matlab GUI underlied with signal processing algorithms, capable of achieving a classification accuracy of 96.03%. Successful implementation of ASK will assist to screen infant asphyxia for reference to clinicians for early diagnosis. In addition, ASK also provides an interface to enter patient information and images to be integrated with existing Hospital Information Management System.
