Abstract
UNLABELLED Investigation of features of expression of matrix metalloproteinases (MMPs) is important for both understanding the mechanisms of the pathogenesis of periodontal diseases, and determining the nature of their course in order to choose a correct and timely treatment strategy. OBJECTIVE To establish the value of MMPs for the diagnosis and determination of the nature of the course of periodontitis at the stage of disease manifestation, by morphometrically assessing the expression of MMPs in the gingival biopsy material. MATERIAL AND METHODS Gingival biopsy specimens from 82 patients with rapidly progressing (n=26), chronic simple (n=18), and chronic complex (n=38) periodontitis were analyzed. Morphometric and statistical analysis of the expression of MMPs was carried out using Aperio ImageScope v. 12.4.0.5043, Statistica 10.0, and MedCalc (p<0.05). RESULTS Analysis of the nature of MMP expression in the gingival biopsy material of patients with periodontal diseases showed that MMP2 and MMP13 were approximately equally involved in the development and course of all the studied forms of periodontitis. An increase in the expression of MMP1, MMP8, and MMP14 and a decrease in that of MMP9 are of the greatest importance in the pathogenesis of a rapidly progressing process. The performed ROC analysis confirmed the significance of the parameters of general and stromal expression of MMP1, MMP9, and MMP14, and mainly stromal expression of MMP8 for the differential diagnosis of rapidly progressing periodontitis with chronic forms, including chronic complex periodontitis. CONCLUSION The expression indicators of MMR1, MMR8, MMR9, and MMR14 are most informative in determining the course of periodontitis at the stage of disease manifestation and differential diagnosis of rapidly progressing periodontitis with chronic simplex and complex periodontitis.

Abstract
Two main types of RET/PTC oncogene, named RET/PTC-1 and 3, occur in papillary thyroid carcinomas especially in those from Belarus children after the Chernobyl nuclear accident. Several variants of RET/PTC-3 have also been found, having different break points with respect to the classical RET/PTC-3. To our knowledge, no variant of RET/PTC-1 has been described up to now. We found a post-Chernobyl papillary thyroid carcinoma with an RET/PTC-1 rearrangement characterized by a transcript longer than expected. Sequence analysis of the PCR product obtained after RT-PCR revealed new fusion points between H4 and RET genes. The genomic sequence showed new breakpoints in both H4 intronic and in RET exonic regions. The RET gene breakpoint occurred within exon 11, at variance with the classical form of RET/PTC-1, in which it is in intron 11. As a consequence of this new fusion point, the transcript included 132 nucleotides of exon 11, coding for 44 amino acids of RET protein. Regarding the H4 gene, the classical breakpoint is in the first intron and the cDNA contains a fragment of 339 nucleotides. In our case the cDNA had a longer fragment of H4 involving a total of 1266 nucleotides. Sequencing of genomic DNA revealed a rearrangement breakpoint at position 886 of a new H4 intron located downstream of the 1266 coding region. Furthermore, as a consequence of the activation of a cryptic splicing site, 132 nucleotides of this intron were spliced between the H4 and RET genes. Sequence analysis of the new chimera showed that the original frames of H4 and RET were joint with the intronic sequence without disruption of the open reading frame (ORF). Moreover, the genomic DNA of this case showed transforming activity in the DNA-mediated transfection assay using NIH-3T3 cells. In conclusion, we describe here the first variant of RET/PTC-1 oncogene, which we have termed 'long'-PTC-1, characterized by new breakpoints of both genes involved in the rearrangement and having transforming activity. Similar to previously reported PTC-3 variants, long-PTC-1 has been found in a post-Chernobyl papillary thyroid carcinoma confirming that RET/PTC rearrangements other than the classical forms (RET/PTC-1 and -3) are specifically associated with radiation-induced papillary thyroid cancer.

Abstract
The increase in thyroid carcinoma post-Chernobyl has been largely confined to a specific subtype of papillary carcinoma (solid/follicular). This subtype is observed predominantly in children under 10 in unirradiated populations, but maintains a high frequency in those aged 10-15 from those areas exposed to fallout from the Chernobyl accident. The aim of this study was to link morphology with molecular biology. We examined 106 papillary carcinomas from children under the age of 15 at operation. All were examined for rearrangements of the RET oncogene by reverse transcription polymerase chain reaction (RT-PCR); a subset of these cases were also examined for mutations of the three ras oncogenes, exon 10 of the thyroid stimulating hormone receptor, associated more usually with a follicular rather than papillary morphology, and exons 5, 6, 7 and 8 of the p53 gene, commonly involved in undifferentiated thyroid carcinoma. Rearrangements of the REToncogene were found in 44% of papillary carcinomas in which we studied fresh material; none of the tumours examined showed mutation in any of the other genes. The two rearrangements resulting from inversion of part of chromosome 10 (PTC1 and PTC3) accounted for the majority of RET rearrangements identified, with PTC1 being associated with papillary carcinomas of the classic and diffuse sclerosing variants and PTC3 with the solid/follicular variant.

Abstract
A sharp increase in the incidence of pediatric thyroid papillary cancer was documented after the Chernobyl power plant explosion. An increased prevalence of rearrangements of the RET protooncogene (RET/PTC rearrangements) has been reported in Belarussian post-Chernobyl papillary carcinomas arising between 1990 and 1995. We analyzed 67 post-Chernobyl pediatric papillary carcinomas arising in 1995-1997 for RET/PTC activation: 28 were from Ukraine and 39 were from Belarus. The study, conducted by a combined immunohistochemistry and RT-PCR approach, demonstrated a high frequency (60.7% of the Ukrainian and 51.3% of the Belarussian cases) of RET/PTC activation. A strong correlation was observed between the solid-follicular subtype of papillary carcinoma and the RET/PTC3 isoform: 19 of the 24 RET/PTC-positive solid-follicular carcinomas harbored a RET/PTC3 rearrangement, whereas only 5 had a RET/PTC1 rearrangement. Taken together these results support the concept that RET/PTC activation plays a central role in the pathogenesis of thyroid papillary carcinomas in both Ukraine and Belarus after the Chernobyl accident.

Abstract
After the Chernobyl nuclear accident (April 26, 1986), childhood thyroid carcinoma had a great increase in Belarus and Ukraine, as a consequence of the exposure to iodine radioactive fallout. The epidemiological and clinical features of the disease were studied in 472 patients less than 21 yr old at diagnosis, with differentiated thyroid carcinoma, representing 97.7% of all thyroid carcinomas diagnosed in Belarus between May, 1986, and December, 1995. The results were compared with those of 369 subjects of the same age group, with naturally occurring thyroid carcinoma, observed in Italy and France. Between 1986 and 1989, the number of thyroid cancer cases per year ranged from 3-8 and increased to 31 in 1990, to 66 in 1991, to 72 in 1992, to 93 in 1993, to 96 in 1994, and to 90 in 1995. The age at diagnosis was 14 yr or less in 78.8% (children group) and more than 14, but less than 21, yr in the remaining subjects (adolescents group). Mean (+/- SD) age at the time of the accident was 4.4 +/- 3.4 yr (3.2 +/- 2.3 in children and 8.9 +/- 2.7 in adolescents), the majority of the patients (62.9%) being 5 yr old or less. The time interval between the accident and the diagnosis (latency period) decreased progressively from 7.5 +/- 1.6 yr in children 0-2 yr old at the time of the accident to 6.0 +/- 1.6 yr in those 9-11 yr old. Since 1993, the yearly distribution of new cases showed a decrease in the subjects 9 yr old or more at the time of the accident but not in those 5 yr old or less. This could not be accounted for by a shift of exposed subjects to an age group at diagnosis not included in this study, because only subjects less than 12 yr of age at the time of the accident were considered in this analysis. Mean age at diagnosis in Belarus patients was 11.3 +/- 3.1 yr (10.1 +/- 2.3 in children and 15.7 +/- 1.4 in adolescents), whereas, among patients with naturally-occurring thyroid carcinomas from Italy and France, the majority of cases were diagnosed after 14 yr of age (mean age at diagnosis: 14.6 +/- 4.2 yr). The female-to-male ratio was significantly higher in Italy and France (2.5/1), compared with the ratio of patients from Belarus (1.6/1). Most of the tumors were papillary in both series, but a relatively high proportion of follicular carcinomas (P = 0.0001) was found in Italy/France (15.2%), as opposed to 5.3% in Belarus. Extrathyroidal extension and lymph node metastases were more frequent in Belarus (49.1%, P = 0.0001; and 64.6%, P = 0.002, respectively) with respect to Italy/France (24.9% and 53.9%, respectively). Thyroid lymphocytic infiltration and circulating antithyroperoxidase antibody were more frequent in Belarus patients. Our analysis of Belarus thyroid cancer patients less than 21 yr old showed that the post-Chernobyl increase in thyroid carcinomas involved both children and, to a much lesser extent, adolescents. Subjects 5 yr old or less at the time of the accident accounted for the majority of the patients. No evidence of a decrease in the number of new cases was observed in this age group, as opposed to older subjects. These data support the concept that subjects who were younger at the time of radiation exposure had, and continue to have, a greater risk of developing thyroid carcinoma and strongly suggest that this age group should be carefully monitored in the future. When compared with naturally occurring thyroid carcinoma of the same age group observed in Italy and France, the post-Chernobyl Belarus thyroid carcinomas affected younger subjects, were less influenced by gender, were virtually always papillary, had a greater aggressiveness at presentation, and were more frequently associated with thyroid autoimmunity.

Abstract
Two "new" syndromes of multiple congenital malformations with autosomal-recessive inheritance are presented. One syndrome, found in 2 sibs of nonconsanguineous parents, included microcephaly, agencies of the corpus callosum, pterygium colli, cystic renal dysplasia (CRD) and postaxial polydactyly (PP). The other, found in 2 female sibs of consanguineous parents, included micropolygyria, CRD, PP, and polysplenia. The literature review allows the delineation of a community of 19 "cerebro-reno-digital" syndromes with autosomal recessive inheritance, 14 of which include cerebral anomalies, CRD and PP. Three more autosomal recessively inherited syndromes had CRD (or renal fibrosis) and cerebral anomalies (without digital anomalies), three others involved cerebral and digital anomalies (without renal anomalies), and one further syndrome showed CRD and ectrodactyly (without cerebral defects). Such phenotypical similarity may be attributed to the fact that there are common links in the pathogenesis of the syndromes under study.

Abstract
A comprehensive study (bone roentgenography, arteriography, gross dissection, microscopy of the long bones, and biochemical study of proteoglycan-aggregates in the hyaline cartilage) of the lower limbs in a full-term stillborn with the campomelic syndrome was performed. Hyaline cartilage immaturity of the long bones, dysplasia of growth plates, focal shaft dysplasia, and a defective length of the posterior femur and crus muscles were revealed. The genesis of the bowing and shortening of the long bones in the lower limbs is discussed.

Abstract
Four families with the cryptophthalmos-syndactyly syndrome are reported. Nine affected patients died in perinatal period. Autopsy, performed in 6 cases, revealed renal agenesis (bilateral in 3 and unilateral in 3 cases). These observations together with recent literature data suggest that renal malformations (agenesis or severe hypoplasia) are one of the most common features of the cryptophthalmos-syndactyly syndrome and may serve as one of diagnostic criteria for this entity.

Abstract
An analysis of 33 autopsied cases with the Smith-Lemli-Opitz syndrome (including 8 cases from our practice) is presented. Polydactyly in dead SLOS children was found in 51% (17/33) of cases and occurred significantly more often in this group than in the whole group of SLOS (20-22%). Certain morphological differences in the type of renal, cerebral, pulmonary and pancreatic anomalies indicate the existence of two phenotypically similar SLOS: 1) with polydactyly; 2) without it. The presented data initiate SLOS heterogeneity.

Abstract
Most cases of Wolf-Hirschhorn syndrome occurring among children who die during the perinatal period are not diagnosed by morphologists. However, analysis of the morphological data on the Wolf-Hirschhorn syndrome revels that association of typical external features and abnormalities ofthe brain (shortening of the H2 area of Ammon's horn, dystonic dysplastic gyrae in the cerebellum), eyes (colobomata, microphthalmos, retinal dysplasia) and kidneys (bilateral or unilateral agenesis, cystic dysplasia or polycystosis) with diaphragmatic hernia allows the establishment of a diagnosis of the syndrome without cytogenetic investigation.

A case of "short rib-polydactyly" (SRP) syndrome (type II-Saldino-Noonan) with a detailed study of the bones, muscles and peripheral nerves in the extremities is presented. Analysis of the literature (35 cases with different forms of SRP) and the comparison of clinical, genetic and morphological data lead us to consider that different types of SRP may be related to different alleles of the same gene. Genetic heterogeneity (mutations of different genes) is also possible.

Abstract
We report a stillborn girl with a complex syndrome of microcephaly, lissencephaly, severe subcutaneous edema, atrophic muscles, camptodactyly, syndactyly of toes and fingers, hypoplastic genitalia, and numerous structural changes of the brain and eyes. Similar cases have been reported by Neu et al [1], Laxova et al [2] and Povysilova et al [3]. The above-mentioned syndrome complex is a distinct genetic syndrome, for which we propose the eponym "the Neu-Laxova syndrome." Affected patients resemble each other strikingly and there is usually no doubt about the diagnosis. The Neu-Laxova syndrome is apparently transmitted as an autosomal recessive trait.

Abstract
We report on a postnatally dead, postterm male infant with aprosencephaly and the oculofacial manifestations usually seen in the most severe form of alobar holoprosencephaly -- namely cyclopia and absence of derivatives of the frontonasal process; in addition the infant had the radius aplasia field defect bilaterally, a high VSD, mobile cecum, and penile hypospadias with cryptorchidism. The same syndrome was reported recently by Garcia and Duncan [2]; however, in that case the brain defect was designated "atelencephaly." Since atelencephaly is a less severe form of aprosencephaly we chose to designate the condition in these two patients as "the aprosencephaly (XK) syndrome." Atelencephaly and aprosencephaly may occur also as a single and sporadic malformation. The cause of the aprosencephaly (XK) syndrome is unknown.

The differences both for severity of pulmonary hypoplasia and for the type of associated malformations suggest that this complex of abnormalities is not a single syndrome but a complex of related entities. These entities and some other genetical syndromes may form a "community of malformations" involving facial, skeletal (arthrogryposis, camptodactyly) and placental abnormalities.

Abstract
Two cases of the Smith-Lemli-Opitz syndrome are described, together with the autopsy findings. In both cases, the typical appearance and visceral malformations were present. Hypoplasia of the frontal lobes and corpus callosum, and aplasia of the splenium constitute abnormalities of the brain which may be useful in the diagnosis of this disorder at autopsy. The autosomal recessive mode of inheritance of this syndrome was confirmed.
