Fatal hospital cases from the viewpoint of the forensic medical expert

The number of lethal cases in hospitals keeps decreasing from year to year, whereas the rate of omitted post-mortem examinations increases. The "control" role of autopsy decreases consequently. Autopsy is omitted even in cases that have been considered as possibly "extraordinary" at the beginning of the procedure and this may mean danger also from the viewpoint of criminology. According to the observations of the authors there are still uncertainties (irregularities?) concerning the tasks connected with the autopsy of those who died in hospitals, as legal injunctions are lacking. On the basis of their experiences the authors interpret the related legal measures and describe the essentials of the procedural practice considered by them correct.     

Possible association between maternal recurrent orofacial herpes in pregnancy and a lower rate of preterm birth.

OBJECTIVE: To study the possible association between orofacial herpes during pregnancy and pregnancy complications including preterm birth and low birth weight, since the results of previous studies are inconsistent. METHOD: The population-based large data set of the Hungarian Case-Control Surveillance System of Congenital Abnormalities was used; pregnancies in mothers with and without recurrent orofacial herpes were compared. RESULTS. Of 38,151 newborn infants, 572 (1.5%) had mothers with recurrent orofacial herpes during pregnancy, while 37 577 had mothers with no orofacial herpes. Pregnant women with recurrent orofacial herpes had a higher prevalence of severe nausea and vomiting, threatened preterm delivery, and placental disorders but a lower prevalence of preeclampsia. Mothers with recurrent orofacial herpes during pregnancy also had a somewhat longer (0.4 weeks) gestation (adjusted t = 2.7; p = 0.006) and an obviously lower proportion of preterm births (3.5% vs. 9.3%; adjusted POR with 95% CI = 0.42, 0.27-0.65). However, there was no significant difference in the mean birth weight and rate of low birth weight infants between the two study groups. CONCLUSION: Recurrent orofacial herpes during pregnancy is associated with a smaller proportion of preterm births.     

In-Hospital Patient Education Markedly Reduces Alcohol Consumption after Alcohol-Induced Acute Pancreatitis

Although excessive alcohol consumption is by far the most frequent cause of recurrent acute pancreatitis (AP) cases, specific therapy is still not well established to prevent recurrence. Generally, psychological therapy (e.g., brief intervention (BI)) is the cornerstone of cessation programs; however, it is not yet widely used in everyday practice. We conducted a post-hoc analysis of a prospectively collected database. Patients suffering from alcohol-induced AP between 2016 and 2021 received 30 min BI by a physician. Patient-reported alcohol consumption, serum gamma-glutamyl-transferase (GGT) level, and mean corpuscular volume (MCV) of red blood cells were collected on admission and at the 1-month follow-up visit to monitor patients’ drinking habits. Ninety-nine patients with alcohol-induced AP were enrolled in the study (mean age: 50 ± 11, 89% male). A significant decrease was detected both in mean GGT value (294 ± 251 U/L vs. 103 ± 113 U/L, p < 0.001) and in MCV level (93.7 ± 5.3 U/L vs. 92.1 ± 5.1 U/L, p < 0.001) in patients with elevated on-admission GGT levels. Notably, 79% of the patients (78/99) reported alcohol abstinence at the 1-month control visit. Brief intervention is an effective tool to reduce alcohol consumption and to prevent recurrent AP. Longitudinal randomized clinical studies are needed to identify the adequate structure and frequency of BIs in alcohol-induced AP.     

Regulation of differentiation, proliferation and drug-induced apoptosis in HT58 lymphoma cells

Recently, it has been suggested, that differentiated cells are more resistant to the apoptotic effect of DNA damaging agents possibly due to the decreased activity of “damage detecting/apoptosis triggering” mechanism. Previously, we have shown, that PMA pretreatment reduced etoposide-(ETO) but enhanced staurosporine- (STA) -induced apoptosis in HT58 cells. Data presented here show that the HT58 human, “mature” B-lymphoma cells exposed to PMA secrete more IgM into the supernatant indicating commitment of cells to perform differentiated function. The sensitivity of HT58 cells to ETO- or STA-induced apoptosis is influenced diversely with PMA pre- or posttreatment. Interestingly, the DNA damage (gamma radiation, bleomycin, ETO) or okadaic acic (30 nM) reduced the [PMA+STA] - induced apoptosis.     

Pathogenesis and genetics of neural tube defects

After congenital heart defects neural tube defects (NTDs) is the second most prevalent congenital malformation among birth defects. The average rate of isolated NTDs is 1.4-2.0 per 1000 live births worldwide. The etiology of isolated (nonsyndromic) NTDs is believed to be the result of a combination of genetic predisposition and environmental factors. Over 80 genes believed to be engaged in the neurulations have been identified during the investigation and research of the mouse models. Despite exhaustive research efforts, now spanning several decades, little is known about the actual genetic mechanisms governing the primary events involved in neural tube closure (NTC).     

Retrospective Detection and Complete Genomic Sequencing of Canine morbillivirus in Eurasian Otter (Lutra lutra) Using Nanopore Technology

The Eurasian otter (Lutra lutra) is a piscivorous apex predator in aquatic habitats, and a flagship species of conservation biology throughout Europe. Despite the wide distribution and ecological relevance of the species, there is a considerable lack of knowledge regarding its virological and veterinary health context, especially in Central Europe. Canine morbillivirus (Canine distemper virus (CDV)) is a highly contagious viral agent of the family Paramyxoviridae with high epizootic potential and veterinary health impact. CDV is present worldwide among a wide range of animals; wild carnivores are at particular risk. As part of a retrospective study, lung-tissue samples (n = 339) from Eurasian otters were collected between 2000 and 2021 throughout Hungary. The samples were screened for CDV using a real-time RT-PCR method. Two specimens proved positive for CDV RNA. In one sample, the complete viral genome was sequenced using a novel, pan-genotype CDV-specific amplicon-based sequencing method with Oxford Nanopore sequencing technology. Both viral sequences were grouped to a European lineage based on the hemagglutinin-gene phylogenetic classification. In this article, we present the feasibility of road-killed animal samples for understanding the long-term dynamics of CDV among wildlife and provide novel virological sequence data to better understand CDV circulation and evolution.
