Change of nitric oxide concentration in men exposed to a 1.5 T constant magnetic field.

This study was carried out in order to determine nitric oxide (NO) production immediately after a 1.5 T magnetic field 30 min exposure to an experimental group, comprising 33 healthy young male volunteers aged 18-26 years old. In addition, a control group, comprising 30 healthy male volunteers aged 19-26 years old, was not exposed to the magnetic field and their NO levels were also measured. The experimental group was exposed using a magnetic resonance imaging (MRI) apparatus. Nitrite and nitrate concentrations were determined by UV-VIS spectrophotometer. The results, related to the parameters measured in this study, were analyzed by one-way ANOVA. Total nitrite concentration in post-magnetic field samples was found to be higher than in pre-magnetic field samples (P < .05).

[The efficacy of botulinum toxin-A in the treatment of hypersalivation in children with cerebral palsy].

OBJECTIVES: We evaluated the efficacy of botulinum toxin A (BTX-A) injection into the submandibular salivary gland to decrease hypersalivation in children with cerebral palsy (CP). PATIENTS AND METHODS: Three children (1 girl, 2 boys; mean age 10; range 7 to 13 years) with CP received BTX-A injections. Due to hypersalivation, two patients dirtied 50 napkins and 5-6 pieces of clothes daily, and one patient dirtied 100 napkins and 8-9 pieces of clothes. The severity of hypersalivation was assessed using the drool rating scale. Injections were performed in the submandibular gland under ultrasound localization and under local anesthesia. The amount of saliva flow at the mouth two hours after the meals and in a duration of 30 minutes was assessed seven times: before the first injection and at different intervals after injections up to 12 weeks. The dose of BTX-A was increased from 5 to 20 units per gland in two patients, while one patient received a standard dose of 20 units. At least 50% reduction in saliva secretion at the end of three months was accepted as a successful outcome. RESULTS: Lower doses of BTX-A were not effective to provide the desired amount of reduction in saliva in two patients. However, application of 20 units resulted in a satisfactory decrease in all the patients. CONCLUSION: In selected patients and with appropriate doses, ultrasound-guided BTX-A injections may improve hypersalivation in patients with CP.

Audiological findings in patients with ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic inflammatory disease. The aim of this investigation was to study the relationship between AS and hearing loss. This study compared 28 patients with AS with 23 age-matched controls. All subjects underwent ENT examination, audiological and acoustic immittance measurements, and auditory brainstem response (ABR) tests. Sensorineural hearing loss was found in 28.6 per cent of the AS patients and in 4.35 per cent of the control group. For hearing levels at 250-500 Hz and 4000-8000 Hz, there was a statistically significant difference between the two groups. Acoustic reflex was not obtained in both ears of four patients and the left ear of one patient. There was a correlation between increase of tympanic volume and limitation in neck movement, between extension of 1-3 interpeak latency and limitation in the neck movement. In conclusion, AS affects the inner ear more than the middle ear.

[Macrodystrophia lipomatosa: a case report].

Macrodystrophia lipomatosa is a rare form of congenital localized gigantism. A forty-year-old male patient presented with complaints of swelling and deformity in the right toe and difficulty in wearing shoes. Conventional radiographic examination, ultrasonography, and computed tomography showed dorsal and medial deviations in the right toe, hypertrophy and degeneration in bone structure, increased density in the medullary bone, and a lipomatous mass with infiltration to the adjacent soft tissue muscles. Partial removal of the lipomatous tissues was performed. Microscopic examination of the specimen revealed fat deposits, ligamentous, and neural tissue elements in normal structure. The patient had no complaints and there was no change in the size of the lesion within a two-year follow-up period.

[Plasental chorioangioma (case report)].

Placental chorioangioma is the most common benign tumor of placenta, encountered in approximately 1% of all pregnancies. Clinical manifestations are rare and usually associated with tumors greater than 5 cm in diameter. They include polyhydramnios, congestive heart failure, anemia, prematurity, growth retardation, and intrauterine fetal death. We report a case of chorioangioma of the placenta in which ultrasonography and Doppler ultrasonography findings were useful in establishing the prenatal diagnosis.

[Digital cameras: a practical solution for radiologists (review)].

Because of the developing technology in computers and internet, the need for creating the digital images and transmission of radiographic images over the internet is increasing. With their improved quality and decreasing price, digital cameras are increasingly attractive for radiologists. In medicine they have already found a place in making a decision by allowing transmission of radiographic images over the internet and archiving of radiological images for personal collections, teaching and publications. When radiographs are digitally photographed, the quality of the images can be also protected. The purpose of this article is to describe the technical information and inform the radiologists about digital cameras, and answer the question 'what kind of digital camera can I buy?'.

The split notochord syndrome with dorsal enteric fistula.

The authors describe a new case of the split notochord syndrome (SNS) with dorsal enteric fistula in an eight-month-old-boy. The child had also central nervous system anomalies including dysgenetic corpus callosum, absence of septum pellucidum, triventricular hydrocephalus, small posterior fossa, and lipomyelomeningocele, gastrointestinal system anomalies such as malrotation, wandering spleen, and right inguinal hernia. The clinical features, embryogenesis, and literature were reviewed briefly.

Pneumatization of the inferior turbinates: incidence and radiologic appearance.

OBJECTIVE: The objective of this work was to determine the incidence and radiologic appearance of pneumatized inferior turbinates (PITs). METHODS: Pneumatized inferior turbinates were investigated among 2500 consecutive cases with coronal paranasal sinus computed tomography (CT) scans that were performed for different reasons between 2000 and 2004. RESULTS: Ten new PIT cases diagnosed with CT were identified. Pneumatization was diagnosed in 2 patients aged 7 and 14 years. Therefore, this is the first time that PIT has been described in the pediatric age group. Complete or incomplete pneumatizations were unilateral in 7 cases and bilateral in 3 cases. In bilateral PIT cases, pneumatizations were asymmetric. In 2 cases, only bulbous parts of the inferior turbinates (ITs) were involved. Inferior turbinate expansion related to pneumatization was not observed in any case. In cases with maxillary sinus communication, axial CT sections revealed a defect on the medial wall of the maxillary sinus. CONCLUSIONS: The incidence of PIT was found to be 1 in 250 cases. It is suggested that most PIT cases may be a result of articulation defects between the maxillary process of the palatine bone and the maxillary bone. In such a situation, the maxillary process of the palatine bone and the nasal process of the maxillary bone, which form the medial wall of the maxillary sinus at the IT level, can attach to the IT separately.
