Nonsurgical rapid maxillary expansion effects on craniofacial structures in young adult females. A bone scintigraphy study.

OBJECTIVE: To evaluate the skeletal effects of nonsurgical rapid maxillary expansion (RME) on craniofacial structures with bone scintigraphy in young adult female subjects. MATERIALS AND METHODS: The material of the present study consists of scintigraphic records taken from 17 early adult females treated with RME. All patients had a bilateral posterior crossbite, transverse maxillary deficiency, deep palatal vault, and dental crowding at the beginning of the treatment. The age range of the patients was 16.1 to 18.8 years, and the mean age was 17.3 +/- 0.86 years. Bone scintigraphy records were obtained before RME (T1), during the splitting of the midpalatal suture (T2), and after the end of active widening period (T3). Repeated measure analysis of variance was used to assess the differences between the periods. In addition, Bonferroni multiple comparison tests were applied to the measurements at which F values were found to be statistically significant. RESULTS: According to the statistical analysis, significant activity changes were found in all regions studied and in all slices. The metabolic activity in all regions showed significant increases up to the separation of the midpalatal suture (T1-T2), whereas the metabolic activity exhibited a remarkable decrease (T2-T3) after the opening of the midpalatal suture. CONCLUSIONS: Scintigraphic records revealed an increase in the regions of interest scores during RME in all regions and all slices. Therefore, it can be speculated that RME has had not only dental effects but also skeletal effects on young adult patients.

99mTc-labelled red blood cell single-photon emission computed tomography for the diagnosis and follow-up of juvenile nasopharyngeal angiofibroma.

AIM: To confirm the usefulness of blood pool scintigraphy with Tc-labelled red blood cells ((99m)Tc-RBCs) in the diagnosis and follow-up of juvenile nasopharyngeal angiofibroma. METHODS: A prospective study design was used. (99m)Tc-RBCs were prepared by a modified in-vivo method. After the rapid intravenous injection of 370-740 MBq of (99m)Tc-RBCs, dynamic imaging of 1-min duration was performed. After dynamic imaging, static acquisitions at 5 min (second phase: blood pool phase) and 2 h (third phase: static image) were obtained. In addition, single-photon emission computed tomography (SPECT) imaging was performed at 2 h. SPECT images were obtained using a rotating gamma camera (GE-Starcam 4000 XR/T). RESULTS: All patients showed no activity in the first phase and mild activity in the second phase (blood pool phase). All patients with juvenile nasopharyngeal angiofibroma showed a prominent increased activity in the third phase and in SPECT images. CONCLUSIONS: This study shows that blood pool scintigraphy with (99m)Tc-RBC SPECT is very accurate, easy to perform and a suitable alternative to pre-operative and post-operative imaging techniques, including computed tomography scan, magnetic resonance imaging (MRI) and MRI angiography, for the detection of juvenile nasopharyngeal angiofibroma.

99mTc-HMPAO labelled leucocyte scintigraphy in the diagnosis of pelvic inflammatory disease.

BACKGROUND: Scintigraphy using leucocytes labelled with 99mTc hexamethylpropyleneamine oxime (99mTc-HMPAO) is widely used for the localization of inflammatory foci and abscesses in cases of acute pelvic inflammatory disease, which is one of the serious health problems of women of child-bearing age. Early diagnosis and effective management of this condition can preserve fertility and prevent serious complications, such as peritonitis and sepsis. AIM: To evaluate the importance of scintigraphy using 99mTc-HMPAO labelled leucocytes in the early diagnosis of patients with pelvic inflammatory disease. METHODS: Fifteen women (mean age 29.2+/-8 years, range 25-46 years) with suspicion of pyogenic pelvic inflammatory disease based on gynaecological examinations, clinical findings and blood tests were included in this study. The patients received 555 MBq 99mTc-HMPAO labelled leucocytes, by injection, and were scanned by scintigraphy 0.5-1, 3 and 24 h later in the anterior abdominal projection. Ten of the patients were then evaluated by abdominal or transvaginal ultrasonography, four by computed tomography and two by both ultrasound and computed tomography. The final diagnosis was made by surgical intervention. RESULTS: Scintigraphy detected pelvic inflammatory disease in five of the patients. In three of them the disease was apparent on the scans taken at 0.5-1 h, and in the other two it was apparent at 3 h. There were no false negative results, and one false positive result. The scan accurately reflected the absence of pelvic inflammatory disease in nine patients showing non-pathological tracer uptake in the lower abdominal region. CONCLUSION: We showed that scintigraphy with 99mTc-HMPAO labelled leucocytes had a sensitivity of 100%, specificity of 90%, overall accuracy of 93%, positive predictive value of 83%, and negative predictive value of 100%. Therefore, we conclude that 99mTc-HMPAO labelled leucocyte scans provide a rapid and highly accurate method for diagnosing pelvic inflammatory disease in women of child-bearing age. This adds an important contribution to the diagnosis of infection and helps determine further operative or conservative treatment.

Bone mineral density in malnourished children without rachitic manifestations.

BACKGROUND: The purpose of this study was to determine bone mineral density (BMD) of lumbar spine in malnourished children without rachitic manifestations, before and after dietary treatment and vitamin D supplementation, and to compare with healthy children of the same community. METHODS: The subjects were 41 children with malnutrition and 21 healthy controls. None of the children had clinical, biochemical and/or radiological rickets features. The patients had moderate 15 and severe 26 malnutrition according to Gomez's criteria. Using the Wellcome Classification, marasmus was diagnosed in 16 children, kwashiorkor in 10 children. The children with malnutrition were given vitamin D supplementation. RESULTS: BMD was lower in children with malnutrition than in controls (P < 0.01). Mineralization significantly effected the severity of malnutrition (P < 0.01). BMD in kwashiorkor was similar to that of marasmus. The mean BMD level of infants receiving 400 IU of vitamin D daily was similar to that of infants receiving 800 IU of vitamin D daily at the beginning of treatment. In two supplementation groups, the BMD gradually increased during the first 3 months of treatment, but this increase in the infants receiving 800 IU of vitamin D daily was significantly higher than that in the infants receiving 400 IU of vitamin D daily. CONCLUSION: Measurements of BMD in children with malnutrition, especially severe malnutrition, are to be recommended in the initial assessment of the severity of osteopenia and in the follow up to monitor the response to therapy. Children with malnutrition should be given 800 IU of vitamin D daily. The loss of BMD must be accepted as a complication of malnutrition.

Bilateral choanal atresia; evaluation with scintigraphy: case report.

Bilateral choanal atresia is a rare congenital anomaly that may cause severe neonatal respiratory distress. The clinical presentation varies from immediate postnatal cyanosis and respiratory distress to nasal obstruction with an associated persistent mucoid discharge. The aim of this study was to evaluate the effect of bilateral choanal atresia preoperatively and postoperatively on nasal mucociliary clearance with the radioisotope method (using technetium-99m macroaggregated albumin). We present a 17-year-old girl with bilateral choanal atresia treated by transnasal endoscopic surgery. The patient was free of symptoms for three years postoperatively. Mucociliary activity was returned to normal images.
