[A study of clinical effects on treatment of 225 cracked-teeth].

PURPOSE: To analyse the clinical effects of cracked-teeth after filling or full crown restoration. METHODS: 225 cracked-teeth were divided into two groups: the early 77 cracked-teeth and the late 144 cracked-teeth according to their clinical features and diagnosis, and then different interventions were applied, the clinical effects were recordered and analysed. RESULTS: There was a significant difference after the early 77 cracked-teeth being treated by filling or full crown rehabilitation after 3 years follow up. The treatment to the late 144 cracked-teeth was excellent after 3 years' observation with root canal therapy or pulp mummification, and finally full crown restoration. CONCLUSIONS: By diving cracked-teeth into different stages and giving corresponding treatment, the cracked-teeth can be preserved successfully.

[Efficacy of the APimicos-B to control and prevent chalkbrood disease in honey bees].

Chalkbrood disease in Apis mellifera is a fungal disease affecting developing brood, infested larvae become mummified. As it is a factorial disease, studies on this pathology are obstructed by the need of some predisposing conditions which must occur for such disease to develop. Thus, many questions are yet to be answered about which treatments to apply. The aim of this work is to evaluate the efficacy of the Apimicos-B, a treatment against chalk brood. To induce the disease, some pieces of combs containing susceptible worker brood both from infected and treated colonies and from infected and untreated colonies were cooled. No significant differences were registered (53.12% and 59.58% of mummification respectively).

[Umbilical stump care in full-term neonates].

OBJECTIVE: The objective of the study was to evaluate the umbilical stump care in the Perinatological Centres in the Czech Republic and to propose a uniform therapeutic procedure in relation to the issue of early release of full-term neonates. DESIGN: An epidemiological data analysis. SETTING: Mother and Child Care Institute, Prague - Podoli. METHODS: The representatives of all the Perinatological Centres (PCs) in the Czech Republic (12 centres) were contacted over the telephone with the aim of evaluating the umbilical stump care in full-term neonates in relation to the period of hospitalisation. The telephonic questionnaire evaluated the following aspects: the treatment method used in the first days after birth; the time of surgical removal and/or leaving the umbilical stump; the technique of surgical access; the treatment after ablation of umbilical stump and the period of hospitalisation. RESULTS: In the first days, antiseptics are used in all the Perinatological Centres of the Czech Republic. All PCs carry out surgical removal of umbilical stump (in 7 centres it is cut off and in 5 centres it is removed through abscission). In 11 centres, the surgical removal takes place 36-48 hours after birth; in 1 centre it takes place 60-72 hours after birth. After removal, antibiotics are applied locally in 2 centres and antiseptics are applied locally in 10 centres. The period after which neonates were released was > or = 72 hours in 8 centres and > or = 96 hours in 4 centres in the case of full-term neonates after spontaneous birth. CONCLUSION: The uniform practice of the Perinatological Centres in the Czech Republic is sterile surgical removal of umbilical stump. However, with regard to early release and after-care, the current trend is to prefer a non-surgical method with spontaneous mummification and detachment of umbilical cord.

A report of decomposition rates of a special burial type in Edmonton, Alberta from an experimental field study.

Regional studies that examine decomposition rates of certain faunal remains can help to determine time since death. Forensic anthropologists have long used qualitative decomposition data, but linking these to more quantitative data could improve time since death estimations. Experiments were developed in which domestic pigs (Sus scrofa) were buried with varying characteristics then excavated and observed over a period of 15 months in Edmonton, Alberta. Data recorded after two weeks, five weeks, three months, one year, and 15 months were correlated with stages of decomposition as well as time since death, climate data, grave type, clothing, burial depth, and other factors. Results from these experiments provide useful regional information about stages of decomposition in a burial context. Pigs buried in June were skeletonized by approximately three to five weeks, while those buried in May were skeletonized between five weeks and three months. Climate data, insects, and grave type contributed the most to advanced decomposition, mainly in the form of mummification, and skeletonization.

[ABO blood group typing in forensic autopsies].

In forensic science and medicine the ABO system has been a major focus, since the record of this blood system is a very prevalent one and A, B and O(H) antigens on erythrocytes are also associated with other cells and tissues throughout the body and are known to be considerably stable to the such violent conditions as heating or drying. However the determination of the ABO grouping from the body often encounters the difficulty due to haemolytic erythrocytes, and putrefaction, mummification or skeletonization of the body during post-mortem interval. In this presentation I review the merit and demerits of the ABO blood-grouping methods utilized in my division at the forensic autopsies according to the haemagglutination, absorption-elution and histochemical techniques and ABO genotyping method. It is important for ABO grouping to know the distribution of the ABO antigen in the body. I would like to emphasize that the species identification prior to ABO grouping is an important procedure because forensic materials such as from saliva, urine and seminal fluid might be contaminated with the fluid from animals, and DNA extracted from vertebrate species might be amplified with the primer for ABO genotyping and the amplified PCR products might be hybridized to those from human.

[Investigation of the current situation on clinical application of endodontic treatments in Shanghai municipality].

PURPOSE: To investigate the present state of endodontic treatments applied in Shanghai municipality. METHODS: A questionnaire survey about clinic application of three endodontic treatments including pulp mummification (PM), resinifying therapy(RT) and root canal therapy(RCT) was conducted by 136 dentists of 42 hospitals selected from three different types of hospitals in Shanghai. The questionnaire concerned the proportion and the scale of three treatments used clinically , the indications, the evaluation of the curative effect and the prospective application in future. SAS6.04 statistical software was used for Chi square test and Kruskal-Wallis test. RESULTS: (1) PM and RCT were applied widely, RT was seldom used. There was significant difference in the proportion using PM among three different types of hospitals (P<0.001). (2) PM was primarily applied to the teeth suffering from acute or chronic pulpitis, especially molars with vital pulp.(3)Good long-term curative effect was the primary factor affecting dentists to chose endodontic treatment.(4) Most dentists affirm that the best curative effect would be obtained for RCT, however, the effect was uncertain for PM to treat acute or chronic pulpitis. CONCLUSION: The current situation of clinical use of endodontic therapeutic methods in Shanghai falls some short of the concepts accepted internationally. But in general, RCT should be popularized while PM should be eliminated gradually.

[Finger tip amputations in children].

Among the various alternative forms of treatment of digital tip amputations, replantation of the amputated tip as composite graft or conservative treatment (healing by secondary intention) are of special interest for the management of fingertip injuries in children. From 1986 until 1987, the authors treated thirteen fingertip amputations in children between one and eight years of age (mean 3.5 years). In twelve cases, the amputated tip was reattached as composite graft, one injury healed by secondary intention. Twelve children were reexamined according to a prospective protocol after a mean follow-up time of 3.4 years. In three cases, primary healing of the replanted tip could be observed, in eight cases partial necrosis and superficial mummification preceded complete healing. At follow-up, seven cases presented with an anatomical tip, four with a slight asymmetry. Distal phalangeal length was identical to the opposite side, but in two cases a maximal loss of length of 2 mm was observed. Fingernails showed no significant deformities, although nail bed injuries had occurred in 90% of the cases. Sensitivity was normal in all cases. Child and parents considered the final result excellent in 75% and good in 25%. Reattachment as composite graft or conservative treatment for management of fingertip amputations in children (Zone I to III according to Rosenthal) is recommended and discussed.

Some historical aspects of the surgical treatment of the infected maxillary sinus.

Sinus surgery probably originates from the time of the New Kingdom of ancient Egypt. Instruments were used to remove the brain through the nose as a part of the mummification process. The interest in the pathology of the maxillary sinus started to rise in the 17th century. Antral trephination for suppuration was the most common maxillary sinus operation in that period. An oro-antral fistula was often created by the extraction of a molar to drain the infected maxillary sinus daily. Later on the anterior wall of the maxillary sinus was opened through the canine fossa and was kept open for irrigation. Caldwell (1893), Scanes Spicer (1894) and later Luc in 1897 closed the canine fossa incision after an intranasal antrostomy and the removal of the infected mucosa. This so-called Caldwell-Luc procedure is still the most commonly used maxillary sinus operation today. After the introduction of the endoscopy in the beginning of this century endonasal surgery has been developed in the last decades into one of the important surgical procedures for maxillary sinus infections today.

Abortion of a mummified fetus associated with short uterine body in a mare.

A mummified fetus was aborted at 284 days of gestation from a Quarter Horse mare with a history of consecutive abortions. The abortion occurred 12 days after administration of supplemental progestogen had been discontinued. Results of a breeding soundness evaluation revealed that this mare had a short uterine body. Other abnormalities were not discovered. This condition may have been responsible for repeated abortions in this mare, and may represent a cause of fetal mummification other than twin pregnancy in mares.

The activity of Aspergillus ochraceus (fungi) on replete females of Rhipicephalus sanguineus (Acari: Ixodidae) in natural and experimental conditions.

Aspergillus ochraceus Wilhelm was isolated from Rhipicephalus sanguineus (Latreille) ticks infected under natural conditions, and developing an illness characterized by absence of oviposition, mummification and death. From the histological sections, it is deduced that A. ochraceus colonized the ticks via the anus, as posterior gut and Malpighian tubules are invaded. The experimental inoculation was carried out on replete female ticks; a disease alike to that observed in naturally infected ticks developed only when specimens are placed under a relative humidity near saturation.

Congenital malformations in sheep resulting from in utero inoculation of Cache Valley virus.

Serologic evidence indicated that an episode of congenital abnormalities in sheep was caused by Cache Valley virus (CVV), a bunyavirus indigenous to the United States. To determine the teratogenic potential of CVV in sheep, fetuses were infected in utero between 27 and 54 days of gestation with an isolate (CK-102) obtained in 1987 from a sentinel sheep in San Angelo, Texas. The dams of these fetuses were euthanatized between 28 and 75 days after inoculation, and the fetuses were examined for malformations. Twenty-eight of 34 fetuses had congenital abnormalities, including arthrogryposis, hydranencephaly, mummification, reabsorption, and oligohydroamnion. Virus was isolated from the allantoic fluid of 11 of 17 fetuses euthanatized at less than 70 days of gestation. The virus-positive fetuses, which were all negative for CVV-neutralizing antibody, had lesions ranging from none to severe arthrogryposis and hydranencephaly. Virus was not recovered from the allantoic fluid of fetuses after 76 days' gestation when CVV-specific antibody could be detected in 5 of 8 fetuses examined. The 2 fetuses infected on days 50 and 54 of gestation appeared normal and 1 had antibody to CVV.

[Abdominal pregnancy. An unusual case].

A general review is made about concept, incidence and clinical features of abdominal pregnancy. The early and accurate diagnosis of an abdominal pregnancy is very important in order to avoid catastrophic hemorrhage from placental separation. A case is reported of a young woman hospitalized at Morelia's General Hospital, SSA, with an abdominal pregnancy. The fetus died about 26th week and underwent mummification. Some time later the fetus spontaneously divided and the lower segment extruded through the intestines. The remain upper thoracic and cephalic segment was removed at laparotomy closing an intestine stoma; 60% of the placenta was also removed. The postoperative course was uneventful.

[Anatomic contribution to the study on the variety of fibrous formations of the arm in humans].

The authors have examined an anatomical preparation of a human upper limb preserved in the Anatomical Museum in Bologna. The specimen was formed by bone, fibrous formations, musculus biceps brachii and musculus coracobrachialis. The soft parts were kept in situ and dried by mummification. The humerus showed abnormalities at its proximal extremity (Fig. 1) and the muscles displayed fibrous varieties: a) a fibrous sheet (Fig. 1, 2) connected the caput brevis of the musculus biceps brachii to the articular capsule of the shoulder joint; b) an aponevrosis (Fig. 1, 3) connected the musculus coracobrachialis to the same articular capsule and the humerus. These observations were discussed from an evolutionary and functional point of view.

Effect of bluetongue virus on reproduction in sheep and cattle.

Bluetongue virus (BTV) has been shown to be arbortigenic and teratogenic. After transmission of BTV under natural and experimental conditions the consequences of vertical transmission in pregnant sheep or cattle are variable. Factors that influence reproductive consequences are the stage of gestation, characteristics of the virus, source and concentration of virus inoculum, placentation, season and the method and route of infection. Reproductive consequences vary greatly in degree but in general include infertility, abortion, mummification of the fetus, stillbirths and congenital anomalies and dysfunctions in the live offspring. Immunological unresponsiveness, sporadic viremia and development of "late disease" were consequences of vertical transmission in offspring of infected cattle. Perpetuation of BTV through 3 generations in cattle was documented. The presence of BTV in semen of infected bulls has been demonstrated.

Pathogenesis and epidemiology of border disease.

The pathogenesis of BD virus infection of sheep is reviewed briefly. The most serious consequences occur when susceptible pregnant sheep are infected. The virus crosses the placenta readily and can cause foetal death with resorption, mummification or stillbirths. Other lambs survive, however, and are born with varying degrees of tremor and/or hairy fleeces. Many such "hairy-shaker" lambs die shortly after birth but survivors gradually recover. These survivors plus other apparently normal lambs can be persistently infected with virus and excrete it constantly often for the rest of their lives. It is these persistently infected sheep that are the key to the epidemiology of the virus and may be responsible for its introduction into a susceptible flock. In addition, cattle grazed with sheep are potentially an important source of pestiviruses capable of causing BD since in some herds the prevalence of cattle persistently infected with pestivirus is one to three per cent. Results are presented of studies on antigenic relation ships among Scottish isolates of cattle pestiviruses (BVD) and BD viruses, and the conclusion drawn that while a single strain of BVDV may be suitable for use as a cattle vaccine this would not be very efficacious in preventing BD since two antigenically distinguishable strains of BD virus have been identified. An effective vaccine against BD would have to protect sheep against both these strains and ideally a cattle vaccine should also contain both strains.

Porcine parvovirus: propagation in microcarrier cell culture and immunogenic evaluation in pregnant gilts.

Porcine parvovirus was propagated in PK-15 cells cultured in roller bottles or on microcarrier beads. After inactivation, the virus was used as antigen in the preparation of vaccines. The immunogenic potency and safety of the vaccines were evaluated in specific pathogen free pregnant gilts and guinea pigs. Experimental challenge tests determined the efficacy of the vaccine in preventing porcine parvovirus transplacental infection. Neither viral antigens nor specific antibodies were detected in fetuses from vaccinated gilts. In contrast, fetal death and, or, mummification occurred when unvaccinated gilts were infected. Both virus and, or, antibodies were also detected in fetuses from these unvaccinated gilts. Serum conversion after vaccination was assayed by microserum neutralisation using guinea pig erythrocytes as cell indicators and by haemagglutination inhibition tests. Viral antigens in fetal tissues were detected using ELISA, the immunobeads technique, the haemagglutination test and by virus isolation.
