[Usefulness of thoracic imaging and computed tomography in evaluation of neoplastic changes of lungs and mediastinum in children]. / Przydatnosc zdjecia przegladowego klatki piersiowej i tomografii komputerowej w ocenie zmian nowotworowych pluc i sródpiersia u dzieci.

Radiological methods of imaging diagnostics allow to evaluate exactly and to monitor the treatment course of pathological lesions in chest. Basic examinations are: plain chest X-ray and computer tomography. Optimal diagnostic algorithm of neoplastic changes in chest is not always univocally defined. The aim of the study is to compare the results of estimation of the presence and type of neoplastic changes in mediastinum and lungs based on X-ray and computer tomography. The results indicate that initial and control X-ray examination allows to diagnose mediastinal lymphadenopathy coexisting with pulmonary hilus extension. CT is used to diagnose and monitor lung tissue and mediastinal changes.

[Kawasaki disease--personal observations]. / Choroba Kawasaki--obserwacje wlasne.

The aim of the study was to analyse two cases of Kawasaki disease--the first one with myocardial infarction and the second with positive outcome. Kawasaki disease is a fever disease usually occurring in very young children. Vasculitis is a characteristic feature of Kawasaki disease. Etiology of this disease is unknown. Diagnosis is based on typical clinical symptoms such as: fever, rash, conjunctivitis, lymphadenitis colli, inflammation of the mucous membranes, erythema of the hands and feet. The treatment can prevent thrombosis, myocardial infarction which are the most serious complications of the disease. Kawasaki disease is treated with intravenous gamma--globulin therapy and high dosage acetylsalicylic acid at the beginning of the disease. Such a treatment of Kawasaki disease prevents the coronary vessel lesions.

[Own experience in the application of midazolam (Dormicum) before the diagnostic examinations an short surgical procedures in children]. / Doswiadczenia wlasne w zastosowaniu midazolamu (Dormicum) przed badaniami diagnostycznymi i krótkimi zabiegami chirurgicznymi u dzieci.

In this paper the evaluation of midazolam (Dormicum) efficiency in obtaining basic sedative effect in 36 children during diagnostic examinations and short surgical operations was done. In 26 patients good sedative effect was obtained. Forgetfulness was present in 17 from 25 patients above 2 years of life, and partial in the rest 8 patients. Fear reactions were observed in 10 children with lower doses of this medicine. Side effects were observed in 8 patients, and had a transient character and were not dangerous for the patients' life.

[Multi-organ tuberculosis in a child: diagnosis and therapeutic problems]. / Wielonarzadowa gruzlica u dziecka, trudnosci diagnostyczne i lecznicze.

Diagnostic and therapeutic problems in the course of tuberculosis in a 4 year old boy were described. First symptoms of disease such as specific inflammation of lymph nodes were observed in THE third month of liFe. After typical antituberculous treatment the signs of disease regressed. In consequence of the contact with an individual expeCtorating tubercle bacilli superinfection and generalization of the disease took place what led to the boy's death.

Actions of desmopressin and vasopressin on the perfused nasal vasculature of the dog.

Desmopressin and vasopressin were injected into the blood supply of the bilaterally perfused nasal mucosa of the dog. Nasal vascular resistance and, in some experiments, nasal airflow resistance and the secretory output of the lateral nasal gland were measured on both sides. Systemic arterial blood pressure was recorded. Desmopressin caused a dose-related vasodilation on the side of injection with no changes in systemic arterial blood pressure or secretion by the lateral nasal gland. Nasal airflow resistance did not change significantly. Vasopressin increased nasal vascular resistance on the side of injection with no changes in the systemic arterial blood pressure or secretion by the lateral nasal gland. Nasal airflow resistance did not change significantly. Thus desmopressin dilates the nasal vascular bed and vasopressin constricts it. The relevance of these findings to the use of the two agents applied into the nose in clinical practice is discussed.

Asymmetric reflex responses of the nasal and tracheal vasculatures of the dog.

Both sides of the nasal vasculature of the dog in vivo were perfused separately, with measurement of vascular resistance responses to stimulation of various nerves. Stimulation of the central end of a cut superior laryngeal nerve caused an ipsilateral vasodilation (-4.98%) and a contralateral vasoconstriction (+3.96%), the difference being statistically significant (P < 0.01). Stimulation of a glossopharyngeal nerve caused vasodilation on both sides, the ipsilateral (-17.52%) being greater than the contralateral (-6.33%) response (P < 0.05). Mechanical stimulation of the nasal mucosa caused little ipsilateral change (+0.47%) and a weak contralateral vasoconstriction (+3.78%; P < 0.01). Stimulation of the central end of a cervical vagus nerve caused vasodilations on both sides, the ipsilateral (-9.75%) being greater than the contralateral (-5.73%) change (P < 0.05). With bilateral perfusions of the cervical tracheal arteries, stimulation of a superior laryngeal nerve caused vasodilation on both sides, the ipsilateral (-10.1%) being greater than the contralateral (-7.4%) response (P < 0.05). Stimulation of the central end of a vagus nerve caused vasoconstrictions on both the sides, the ipsilateral (+37.4%) being greater than the contralateral (+10.8%) change (P < 0.05). Thus various nervous inputs from the nose, pharynx, larynx, and vagal distribution cause asymmetric vascular responses both in the nose and in the cervical trachea.
