Ammonolysis of Cobalt Molybdenum Oxides - In Situ XRD Study.

The reduction of cobalt molybdenum oxide under an ammonia atmosphere resulting in the formation of ternary interstitial nitride CoMoN was studied. Intermediate phases were identified by an in situ powder X-ray diffraction using a reaction chamber. It was supplemented by a thermogravimetric analysis of the process.

[Atrial fibrillation in athletes].

Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting up to 1-1.5% of the population. Regular physical activity reduces the risk of cardiovascular diseases, however several studies have shown paradoxically increased incidence of AF in people practicing sport, especially in elite athletes.

Multiple congenital epuli (congenital granular cell tumours) in the newborn: a case report and review of literature.

Congenital epulis of newborn is very rare benign intraoral entity of uncertain ethiology. Histologically the lesion is similar to the granular cell tumour of an adult but immunohistochemical stainings prove their different origin. Treatment involves surgical excision, recurrences are rare.

Polymorphisms in CHDH gene and the risk of tooth agenesis.

Background: Tooth agenesis is one of the most common anomalies of human dentition and is due to a complex and not fully elucidated etiology. The purpose of this study was to evaluate the possibility that polymorphic variants of genes encoding the main folate and choline metabolism enzymes might be associated with the risk of hypodontia in the Polish population.

Methods And Results: We analyzed 21 polymorphisms of 13 candidate genes and found that single nucleotide polymorphisms (SNPs) in the CHDH gene are significantly correlated with the risk of dental agenesis.

The use of drotrecogin alfa (activated) in severe sepsis during acute pancreatitis - two case studies.

Background: Twenty-five percent of patients with diagnosed acute pancreatitis (AP) present a severe form of it. One of the most widespread complications of such a form is severe sepsis or septic shock, in which mortality can reach 80%. A complication of this state is multiple organ failure, which requires multi-directional treatment in an intensive care unit (ICU).

[Use of pedicled cutaneous groin flaps in distal reconstruction of the upper extremity].

In the years 1981-1997 at the Department of Plastic Surgery Medical Centre for Postsgraduate Education in Warsaw 116 patients were treated surgically using groin flaps and 97 patients using a pedicled cutaneous groin flap. This paper reports the results of the later technique. Reconstructions were performed in 10 female patients aged 18-58 (mean age 37.

[Rhabdomyosarcoma of the middle ear in childhood].

The authors have described a case of a 2.5-year-old boy who suffered from rhabdomyosarcoma of the middle ear. The clinical course, differential histopathology diagnosis and dynamic growth of the tumor have also been presented.

Congenital temporomandibular joint ankylosis--a case report.

A case of congenital temporomandibular joint (TMJ) ankylosis which caused facial disfigurement, significant reduction in mouth opening, difficulties in feeding and breathing, and general interference with physical and mental development is presented. The wide range of manifestations exceed the typical picture of TMJ ankylosis and resemble a syndrome rather than an isolated defect of the TMJ.

[Analysis of menstrual cycle irregularities in adolescents].

The analysis covered 1615 teenagers, patients of Child's & Adolescents Gynaecology Clinic in Lódź in the years 1980-1990. 338 of them had troubles in the menstrual cycle. Majority of them (55.

An objective evaluation of retrocochlear function by means of CNT (Cochlear Nerve Tester).

Indications for hearing implants in profoundly deaf patients have been presented. Auditory pathway status was evaluated by application of electric stimulation of cochlear nerve. The electric stimulus originated from Cochlear Nerve Tester.

[Syndrome of double uterus with occluded vagina, lack of kidney and ovarian dermoid cyst on the same side].

The developmental anomalies of the reproductive system are frequently accompanied by urinary system anomalies. Among the development anomalies of the urogenital system, the syndrome of double uterus with occluded one vagina and lack of kidney on the same side is very rarely encountered and, in view of this, little known. This anomaly may be frequently accompanied by other developmental anomalies.

Ehlers Danlos syndrome type I with novel dental features.

The clinical, radiographic and histologic findings are described in two cases of Ehlers Danlos Syndrome Type I with novel dental features. Defective dentinogenesis principally affecting the mandibular incisors result in aplasia or hypoplasia of root development predisposing to localized periodontal disease. A striking radiographic appearance with a bulbous enlargement of the roots together with pulp stones is seen in other teeth.

[An objective evaluation of retrocochlear structures in the auditory pathway by means of CNT (cochlear nerve tester)].

Indications for hearing implants in profoundly deaf patients have been presented. Auditory pathway status was evaluated by application of electrical stimulation of cochlear nerve. The electrical stimulus originated from Cochlear Nerve Tester.

[What do we know about Ludwig van Beethoven's deafness?].

The authors described some details from the life of Beethoven, emphasizing his problem linked with his progressive deafness. The etiology of the deafness is not known. The authors discussed their own hypothesis of "music language".

[Analysis of the relations between selected symptoms of inflammation of the genital and urinary organs and invasion of Trichomonas vaginalis].

Data concerning 604 girls up 18 year old were analysed. On the basis clinical symptoms and results of culture of various biological materials on selected media--the monofocal Trichomonas infection concerning the most often vulva and vagina, rarely urethra or other regions of urinary organ as well as the multifocal Trichomonas infection, particularly complicated by mycosis were proved. It was found the convergence statistically significant (P less than or equal to 0.

[Incidence of Trichomonas vaginalis infection among girls from the Lódź population in the last 25-year period].

19,024 girls (aged: from 0 to 18) attending the Pediatric Gynaecology Outpatient Department and the Center for Treatment of Parasitic and Mycotic Diseases were examined. The diagnosis of infection with T. vaginalis was based on preparations using various methods and cultures on specific media, from vaginal content and urine.

A Polish variant of isolated dentinogenesis imperfecta with a generalised connective tissue defect.

A case is described of four generations of a Polish family with characteristic features of dentinogenesis imperfecta, who also presented with a variety of generalised connective tissue features, suggestive of a structural gene mutation causing abnormalities in connective tissues other than dentine.

[Horizontal osteotomy of the mandibular body with transfer of the inferior dental nerve].

In a patient with developmental facial asymmetry resulting from unilateral mandibular hyperplasia, irregular height of the mandibular body was strongly manifested on the affected side. Since a large portion of the inferior border of the mandible predicted to be cut off contained almost the whole of the lower alveolar nerve, transfer of the latter was employed. The nerve was surgically isolated along its course, and secured by being lifted while horizontal osteotomy of the mandibular body was performed.
