Cooperation of the maxillofacial and plastic surgeon in reconstructive surgical procedures in gunshot injury - a case report.

Lower and middle face defects resulting from gunshot wounds often cause severe functional and cosmetic deformities. The purpose of this case report is to refer to our experiences in the treatment of facial gunshot trauma associated with attempted suicide that resulted in a complex facial injury. The goal of the treatment of complex facial injuries is a proper reconstruction of the hard and soft tissue defects and sufficient rehabilitation of the relevant functions, such as speech, nutrition and appearance. A close cooperation of the maxillofacial and plastic surgeon is essential to achieve a satisfactory outcome.

Dental treatment recommendations and coronavirus disease 19 (COVID-19).

Health is a state of complete physical, mental and social well-being. The outbreak of coronavirus disease 2019 (COVID-19) in the area of Wuhan, China, has evolved rapidly into a public health crisis and has spread exponentially to other parts of the world.There is strong evidence that this novel coronavirus is similar to coronavirus species found in bats and potentially pangolins, confirming the zoonotic nature of this new cross-species virus-mediated disease.Dentists provide support and management for patients. They proceed in accordance with the current guidelines of the government of each country as well as with the valid standards and preventive, diagnostic and therapeutic procedures for COVID-19.This article mainly focuses on the recommended methods in dental medicine designed to protect patients and healthcare professionals (Tab. 2, Ref. 29). Keywords: coronavirus, COVID-19, dental strategies, dental treatment recommendations.

Motivational interviewing for improving periodontal health.

Periodontal health should be defined as a state free from inflammatory periodontal disease that allows an individual to function normally and not suffer any consequences (mental or physical) as a result of past disease. Tissues located in the vicinity of implants, known as peri-implantation tissues, have specific and in many ways similar anatomy. The elaborate protocol of preventive measures to ensure periodontal health is extremely important. There is compelling evidence that motivational interviewing frequently leads to more favourable clinical responses than conventional preventive tools. Herein, we describe that the periodontal health can serve as a vital common reference point for assessing disease, determining meaningful preventive methods and treatment outcomes. This article mainly focuses on the role of new clinical data regarding periodontal health and motivational interviewing, which received a particular attention in recent years such as motivation for abidance and on the prognosis of periodontal health (Tab. 3, Ref. 26).

Hyaluronic acid application vs arthroscopy in treatment of internal temporomandibular joint disorders.

AIMS: The goal of this study was to compare the treatment outcome after two different treatment modalities in cases of disc displacement of the temporomandibular joint diagnosed via magnetic resonance technique, namely surgical procedure in form of arthroscopic lysis and lavage vs. hyaluronic acid superior joint space application. MATERIALS AND METHODS: Magnetic resonance imaging was performed before and one year after treatment. Simultaneously, pre- and post-treatment visual analogue scales and maximal mouth opening distance were documented. RESULTS: In our study, out of the total of 145 patients who were initially diagnosed with magnetic resonance imaging to have internal derangements and treated with arthroscopic lysis and lavage or hyaluronic acid application, we observed progression of internal derangement in 27 cases (18.6 %), improvement in 37 cases (25.5 %) and stationary state in 81 patients (55.9 %). Both treatment methods significantly improved the followed maximal mouth opening distance and visual analogue scale, as confirmed upon the 12­month follow-up examination. Maximal mouth opening was 4.7mm for hyaluronic acid application and 12.2mm for arthroscopic lysis and lavage (p<0.005). The mean visual analogue scale values decreased from 6.2 to 2.1 for hyaluronic acid application and from 6.9 to 1.2 for arthroscopic lysis and lavage (p<0.005). CONCLUSION: Our study shows that both arthroscopic lysis and lavage and hyaluronic acid injections are effective and safe in the treatment of disc displacement in the temporomandibular joint (Tab. 3, Ref. 30).

Therapeutic effects of arthrocentesis in treatment of temporomandibular joint disorders.

OBJECTIVE: Analyse, compare and evaluate the effects of the treatment arthrocentesis with a control group of non-steroid drugs treated patients. MATERIAL AND METHODS: 1752 out-patients (1293 females, 459 males) were examined within the years 2013-2017. We evaluated the following criteria: gender, age, visual analog scale for pain (VAS), inter-incisal distance and reducing intake of orally administered analgesics. RESULTS: The pain level of the group of patients with arthrocentesis had stabilized at mark 2.5 on the pain scale, unlike in the control group after treatment with non-steroidal anti-inflammatory drugs, pain had stabilized at mark 9 on the pain scale. The inter incisal distance amongst the first group was 37 mm and in the control group only 27 mm, after completed treatment. The amount of applied analgesics in the group with arthrocentesis decreased to 100 mg daily, while in the control group, the dose was adjusted to 700 mg daily. CONCLUSION: In the observed study, arthrocentesis was effective in reducing pain, amount of analgesics per day and improving the mobility of temporomandibular joint (TMJ). The results of this study we use in the ongoing project, that focuses on progressive and innovative methodology of endoscopically assisted arthrocentesis. (Tab. 4, Fig. 5, Ref. 39).

Biodegradable versus titanium plates and screws for paediatric facial skeleton fractures.

OBJECTIVE: The use of biodegradable materials represents a new option in the treatment of paediatric facial skeleton fractures. The benefits of a resorbable system include reductions in time for long-term stability, diminished immobilisation period, and elimination of painful procedures for implant removal. The resorption of the material did not influence bone repair and growth. Bioresorbable plates and screws get completely excreted through physiological routes. MATERIAL AND METHODS: The age of the patients ranges from that of pre-schoolers till 18 years. The mean age of boys and girls was 12.18 (range 4-18 years) and 13.59 (range 5-18 years), respectively. RESULTS: During the ten-year period, 168 children and adolescents, 136 boys and 32 girls, were treated. The conservative treatment was performed in 67 patients (39.9 %). Open surgical reduction was performed in 101 patients (60.1 %). Bioresorbable plates were applied in 44 patients (43.6 % of surgically treated). CONCLUSION: The implementation of biodegradable osteosynthetic materials is optimal for the treatment of fractures of the middle third of the facial skeleton, lower part of the upper third of the facial skeleton, mandibular body and parasymphysis (Tab. 3, Fig. 3, Ref. 31).

The influence of orthodontic non-extraction treatment on the change in the inclination and position of incisors in the Europoid race.

AIM: To detect post-treatment change in the inclination and position of incisors in cases treated with orthodontic non- extraction therapy. MATERIALS AND METHODS: The group consisted of 102 patients without extractions in lower and upper dental arch during orthodontic treatment. Cephalogram examination evaluated the position of the lower incisor to point A by Downs-pogonion line (-1 to APo) and inclination of the lower incisor to mandibular line (-1 to ML), position of the upper incisor to nasion-pogonion line (+1 to NPo), inclination of the upper incisor to nasion-sella line (+1 to NS) and the size of the inter-incisival angle between upper and central lower incisor (-1 to +1). RESULTS: In 58 % of cases, the difference in post-treatment and pre-treatment changes in the position of the (-1 to Apo) was within ± 2 mm, which we considered stable. Statistically significantly higher values after treatment were in unstable rather than in stable cases with values (-1 to Apo), (-1 to ML), (+1 to NPo). Statistically significantly lower value after the treatment was measured in unstable cases rather than in stable cases with a value (-1 to +1). There was no statistically significantly different value in stable and unstable cases after treatment in values (+1 to NS). CONCLUSION: The number of stable post-treatment cases was only 16 % higher than the number of unstable cases. With the increasing value (-1 to Apo), the value (-1 to ML) and (+1 to NPo) increased, the value (+1 to -1) decreased. The value (-1 to NS) not after treatment was not statistically significantly different in stable and unstable cases (Tab. 6, Fig. 4, Ref. 27).

[Atypical maxillofacial shot wound]. / Atypické strelné poranenie maxilofaciálnej oblasti.

Maxillofacial shot wounds belong to the relatively less frequent injuries. The soft tissues might be affected in particular, however the most of injuries are combined with infliction of hard tissues. Shot wounds by the bow or crossbow are very rare. They might result as a consequence of either accident or suicide. In the literature some cases of a suicidal experiments had been published, all of these cases were due to arrow from the crossbow. There was no injury being documented due to arrow from the bow. The authors present a case of maxillofacial injury done by shoot of arrow from the bow in the course of a child's play.

Successful treatment of extreme acute lead intoxication.

Severe acute lead intoxications are rare and are associated with accidental or purposeful ingestion. There were only few cases of severe to fatal poisonings reported in literature in children. We report a case of acute lead intoxication in a child with extremely high lead blood level of 20.4 micromol/L (422.7 microg/dL), who was treated with chelation and in whom significant organ dysfunction did not develop. Documented significant high level above 3.37 micromol/L (corresponding to 70 microg/dL) in this patient persisted for approximately 24 h. Adequate, single or combined chelatation therapy in early phase of acute lead poisoning is essential for the further patient's outcome.

[Microstructure of subcutaneous lesions in juvenile hyaline fibromatosis]. / Mikrostruktúra podkozných lézií juvenilnej hyalínovej fibromatózy.

Juvenile hyaline fibromatosis is a rare autosomal recessive interstitial disease characterized by nodes and tumours of skin and soft tissues as well as by gingival hyperplasia. The authors described a case of 28-year-old male based on histopathological diagnosis. The patient was admitted to the hospital thrice in his life with the diagnosis of arthrogryphosis. Last time he presented with extensive secondary impetigo in extremities and pachydermia, polymalformation syndrome, multiple subcutaneous tumours, gingival hypertrophy, contractures, osteolytic lesions and positive family history. In histology, tumoriform lesions showed a structureless hyaline matrix often with chondroosseous metaplasia and calcium salts. More or less numerous cells in the matrix had a fibroblastoid appearance with eosinophilic cytoplasm, oval nuclei and frequently pericytoplasmic halo. Electron microscopy revealed dilated cisterns of rough endoplasmic reticulum and a hypertrophied Golgi apparatus. Particles representing calcium salts according to their density were rare. Immunohistochemistry of tumour cells showed vimentin, alpha-1-antichymotrypsin and alpha-1-antitrypsin. The findings concurred with the literature in which, nevertheless, the immunohistochemical picture were not mentioned.

[Juvenile hyaline fibromatosis]. / Juvenilná hyalínová fibromatóza.

BACKGROUND: Juvenile hyaline fibromatosis is a sporadic hereditary disease with autosomal recessive mode of inheritance, characterized by the presence of nodules and tumours in the skin and soft tissues and gingival hyperplasia. The majority of patients are growth retarded, suffer from joint disorders, contractures, osteolytic lesions and have a positive family history. The disease most frequently occurs in children, but may be diagnosed also in adults. Since 1873, when the disease was described by Murray, only a few cases were introduced in the literature. THE AIM AND THE BASIS OF THE STUDY: To present the clinical pattern of a patient diagnosed at the age of 28 and describe also the histopathological, immunohistological and electron-microscopic findings of excisions from the lesions. METHODS: The pathologist in cooperation with clinicians from several disciplines established the diagnosis on the basis of typical histopathological picture and additional immunohistological tests not yet introduced in the literature. RESULTS: Tumorous lesions contained hyaline structureless matrix often with chondroid or even osteoid metaplasia, calcium salts. The matrix contained numerous fibroblastoid-like cells with eosinophilic cytoplasm, oval nucleus and often pericytoplasmic halo. ELMI investigation revealed dilated cisternae of rough endoplasmic reticulum and hypertrophic Golgi apparatus. Sporadically were particles with calcium salts density detected. Immunohistochemical tests revealed the expression of vimentin, alfa1-antitrypsin and alfa1-antichymotripsin by the tumorous cells. CONCLUSION: The authors presented an extremely sporadic childhood disease in an adult. The results are in accordance with the data from the literature. Immunohistochemical picture of "cementicles" has not yet been introduced in the available literature. (Fig. 12, Ref. 25.)

[Oncologic issues gerostomatology]. / Onkoloska problematika v gerostomatologiji.

In collection value we have analyzed 565 patients above 60 years with malignoms in maxillo-facial area (lip, tongue, big salivary glands, gum, floor of the oral cavity and other strictly undetermined parts of mouth) treated during the years 1978 and 1988 in Central Slovakia. Following epidemiological terms have been studied: incidence, age groups, seasonal occurrence, dimension of the tumors and their stage, time for examination of diagnosis, timeliness of determinations of illness, type of the treatment, time of surviving and causes of death. The number of malignant neoplasms after the age of 60 years is growing. The largest number of malignoms was with Ca of lips, tongue and big salivary glands. Mostly half of the patients looked for the medical help in progressive stadium of the disease.
