The Relationship between Bone Mineral Densitometry and Visceral Adiposity Index in Postmenopausal Women / A relação entre a densitometria mineral óssea e o índice de adiposidade visceral em mulheres na pós-menopausa

Abstract Objective It was aimed to compare visceral adiposity index (VAI) levels in patients with normal bone mineral density (BMD), osteopenia, and osteoporosis. Methods One hundred twenty postmenopausal women (40 with normal BMD, 40 with osteopenia, and 40 with osteoporosis) between the ages of 50 to 70 years were included in the study. For females, the VAI was calculated using the formula (waist circumference [WC]/[36.58 + (1.89 x body mass index (BMI))]) x (1.52/High-density lipoprotein [HDL]-cholesterol [mmol/L]) x (triglyceride [TG]/0.81 [mmol/L]). Results The time of menopause from the beginning was similar in all groups. Waist circumference was found to be higher in those with normal BMD than in the osteopenic and osteoporotic groups (p = 0.018 and p < 0.001, respectively), and it was also higher in the osteopenic group than in the osteoporotic group (p = 0.003). Height and body weight, BMI, blood pressure, insulin, glucose, HDL-cholesterol, and homeostasis model assessment-insulin resistance (HOMA-IR) levels were similar in all groups. Triglyceride levels were found to be higher in the normal BMD group, compared with the osteoporotic group (p = 0.005). The level of VAI was detected as higher in those with normal BMD, compared with the women with osteoporosis (p = 0.002). Additionally, the correlation analysis showed a positive correlation between dual-energy X-ray absorptiometry (DXA) spine T-scores, WC, VAI, and a negative correlation between DXA spine T-scores and age. Conclusion In our study, we found higher VAI levels in those with normal BMD, compared with women with osteoporosis. We consider that further studies with a larger sample size will be beneficial in elucidating the entity.

Resumo Objetivo O objetivo foi comparar os níveis de índice de adiposidade visceral (IVA) em pacientes com densidade mineral óssea (DMO) normal osteopenia e osteoporose. Métodos Cento e vinte mulheres na pós-menopausa (40 com DMO normal 40 com osteopenia e 40 com osteoporose) com idades entre 50 e 70 anos foram incluídas no estudo. Para o sexo feminino o VAI foi calculado pela fórmula (circunferência da cintura [CC]/[36 58 + (1 89 x índice de massa corporal (IMC))]) x (1 52/lipoproteína de alta densidade [HDL]-colesterol [mmol/L]) x (triglicerídeo [TG]/0 81 [mmol/L]). Resultados O tempo de menopausa desde o início foi semelhante em todos os grupos. A circunferência da cintura foi maior naqueles com DMO normal do que nos grupos osteopênicos e osteoporóticos (p = 0 018 e p < 0 001 respectivamente) e também foi maior no grupo osteopênico do que no grupo osteoporótico (p = 0 003) . Altura e peso corporal IMC pressão arterial insulina glicose HDL-colesterol e os níveis de avaliação do modelo de homeostase-resistência à insulina (HOMA-IR) foram semelhantes em todos os grupos. Os níveis de triglicerídeos foram maiores no grupo DMO normal em comparação com o grupo osteoporótico (p = 0 005). O nível de VAI foi detectado como maior naquelas com DMO normal em comparação com as mulheres com osteoporose (p = 0 002). Além disso a análise de correlação mostrou uma correlação positiva entre a absorciometria de raios-X de dupla energia (DXA) nas pontuações T da coluna CC VAI e uma correlação negativa entre as pontuações T da coluna DXA e a idade. Conclusão Em nosso estudo encontramos níveis mais elevados de VAI naquelas com DMO normal em comparação com mulheres com osteoporose. Consideramos que novos estudos com maior tamanho amostral serão benéficos na elucidação da entidade.

The effect of low-intensity pulsed ultrasound on rib fracture: An experimental study.

BACKGROUND: In this study, we aimed to investigate the effects of lowintensity pulsed ultrasound on rib fracture healing in a rat model. METHODS: A total of 72 male Wistar-Albino rats were randomly divided into three equal groups. To induce a rib fracture, right thoracotomy was performed under general anesthesia and a 0.5-cm segment was removed from the fourth and fifth ribs. After 24 h of surgery, low-intensity pulsed ultrasound was implemented according to the groups. Group 1 served as the control group for the observation of normal bone healing. Low-intensity pulsed ultrasound was applied at a dose of 20% (2 msn pulse-8 msn pause) 100 mW/cm2 and 50% (5 msn pulse-5 msn pause) 200 mW/cm2 for six min, respectively in Group 2 and Group 3. All subjects were followed for six weeks. Eight animals from each group were sacrificed at two, four, and six weeks for further assessment. Histological alterations in the bone were examined. RESULTS: Although there was no statistically significant difference in osteoblasts, osteoclasts, new bone formation, and lymphocyte count among the groups, histological consolidation was significantly increased by low-intensity pulsed ultrasound. While low-intensity pulsed ultrasound induced osteoblastic, osteoclastic, and new bone formation, it inhibited lymphocyte infiltration. CONCLUSION: Low-intensity pulsed ultrasound, either at low or high doses, induced the histological consolidation of rib fractures and inhibited lymphocyte infiltration. This effect was more prominent in the long-term and at higher dose with increased daily and total administration time. We, therefore, believe that accelerating the natural healing process in patients with rib fractures would enable to treat more effectively in short-term.

Percutaneous treatment of hepatic cystic echinococcosis: the success of alcohol as a single endocavitary agent in PAIR, catheterization, and modified catheterization techniques.

OBJECTIVES: This retrospective study aims at demonstrating the success rate, effectiveness, and advantages of alcohol as a scolicidal and sclerosing agent for the percutaneous treatment of liver hydatid cysts. METHODS: A total of 554 liver hydatid cysts obtained from 347 patients admitted between January 2008 and February 2016 were retrospectively investigated. Of these, 435 (78.5%), 91 (16.4%), and 28 (5%) were classified as Gharbi type 1, 2, and 3, respectively. Type 1 and 2 cysts were treated using PAIR (puncture, aspiration, injection, respiration) and single puncture catheterization methods; type 3 lesions were treated using a modified catheterization technique. Alcohol was used as a scolicidal and sclerosing agent in all procedures. RESULTS: After excluding three lesions (0.5%) because of lack of parenchymal support during catheterization, 274 (49.7%), 250 (45.3%), and 27 (4.9%) of 551 lesions were treated with PAIR, single puncture catheterization, and modified catheterization techniques, respectively. Therefore, a 99.5% of technical success rate was obtained. Major complications in 2 patients (0.5%) and minor complications were observed in 36 patients (10.3%). Mean hospital stay was 1.55±2.3 days (range: 0-23 days). Patients were followed-up for mean 19.6 months (range: 6-83 months), during which recurrences were detected in 19 patients (5.4%). CONCLUSIONS: The use of alcohol as a scolicidal and sclerosing agent during the percutaneous treatment of liver hydatid cysts is associated with a high success rate and low rates of recurrence and complications, and should be considered an important alternative to surgical procedures.

Successful percutaneous treatment of extrahepatic cystic echinococcosis through PAIR and single puncture catheter techniques.

PURPOSE: To demonstrate the successful percutaneous treatment of extrahepatic cystic echinococcosis as an alternative to surgical procedures. MATERIALS AND METHODS: A total of 27 extrahepatic hydatid cysts in 12 patients, the spleen in 8 patients, muscles and soft tissues in 3 patients each and right adrenal gland in 1 patient were treated with PAIR (puncture, aspiration, injection, respiration) or single puncture catheterization methods. As a scolicidal and sclerosing agent, alcohol was used in all patients. RESULTS: Of 27 extrahepatic lesions of hydatid cysts, 24 (88.9%) were Gharbi type 1 (WHO CE 1), and 3 (11.1%) were Gharbi type 2 (WHO CE 3A). Of hydatid cystic lesions, 20 with PAIR and 7 with single puncture catheterization methods were treated. No major complications developed in any patients. Abscesses were detected in two patients (16.6%). Mean total hospital stay was calculated between 1 and 14 days (mean 2.3 days). Follow-up periods ranged between 10 and 62 months (mean 22.3 months). CONCLUSION: Percutaneous treatment for extrahepatic hydatid cystic lesions is an important alternative to surgical procedures because of the high therapeutic success rate, lower rate of complications and shorter hospital stays.

The role of Onodi cells in sphenoiditis: results of multiplanar reconstruction of computed tomography scanning / Papel das células de Onodi na esfenoidite: resultados da tomografia computadorizada com reconstrução multiplanar

Abstract Introduction Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any treatment modalities related to the sphenoid sinus. Objective To evaluate the effect of Onodi cells on the frequency of sphenoiditis. Methods A retrospective analysis was performed in 618 adult patients who underwent high-resolution computed tomography between January 2013 and January 2015. The prevalence of Onodi cells and sphenoiditis was evaluated. Whether the presence of Onodi cells leads to an increase in the prevalence of sphenoiditis was investigated. Results Onodi cell positivity was observed in 326 of 618 patients and its prevalence was found to be 52.7%. In the study group, 60.3% (n = 73) were ipsilaterally (n = 21) or bilaterally (n = 52) Onodi-positive, whereas 39.7% (n = 48) were Onodi-negative (n = 35) or only contralaterally Onodi-positive (n = 13). Of the control group, 48.3% (n = 240) were Onodi-positive and 51.7% (n = 257) were Onodi negative. The co-existence of Onodi cells ipsilaterally was observed to increase the identification of sphenoiditis 1.5-fold, and this finding was statistically significant (p < 0.05). Conclusion The prevalence of sphenoiditis appears to be higher in patients with Onodi cells. However, it is not possible to state that Onodi cells are the single factor that causes this disease. Further studies are needed to investigate contributing factors related to sphenoiditis.

Resumo Introdução As células de Onodi são as células etmoidais mais posteriores, que se prolongam superolateralmente ao seio esfenoidal. Essas células também se encontram em íntima relação com o seio esfenoidal, o nervo óptico e a artéria carótida. Para análise de variações anatômicas antes da implantação de qualquer modalidade terapêutica relacionada ao seio esfenoidal, a avaliação radiológica é obrigatória, Objetivo Nosso objetivo foi avaliar o papel das células de Onodi na frequência de esfenoidite. Método Em nosso estudo, foi feita uma análise retrospectiva em 618 pacientes adultos que se submeteram à tomografia computadorizada de alta resolução entre janeiro de 2013 e janeiro de 2015. Avaliamos a prevalência de células de Onodi e de esfenoidite. Investigamos se a presença de células de Onodi leva a um aumento na prevalência de esfenoidite. Resultados A positividade para células de Onodi foi observada em 326 de 618 pacientes e sua prevalência foi de 52,7%. No grupo de estudo, 60,3% (n = 73) eram CO-positivas: ipsilateral (n = 21) ou bilateralmente (n = 52); e 39,7% (n = 48) eram CO-negativas (n = 35) ou apenas contralateralmente CO-positivas (n = 13). No grupo de controle, 48,3% (n = 240) eram CO-positivas; e 51,7% (n = 257) eram CO-negativas. Observamos que a coexistência de CO ipsilateralmente aumentava em 1,5 vez a associação com esfenoidite e esse achado foi estatisticamente significante (p < 0,05). Conclusão A prevalência de esfenoidite parece ser maior em pacientes com células de Onodi, mas não é possível afirmar que elas são isoladamente o fator causador dessa doença. Novos estudos precisam ser feitos para uma investigação dos fatores contributivos relacionados à esfenoidite.

Amyand's Hernia: Ultrasonography Findings.

BACKGROUND: Amyand's hernia is described as the presence of an appendix vermiformis in the inguinal hernia sac. The incidence of Amyand's hernia is approximately 1% of all inguinal hernias. Amyand's hernia is diagnosed intraoperatively or preoperatively with radiologic examinations. CASE REPORT: Two cases of Amyand's hernia, with and without acute appendicitis, are reported here. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Amyand's hernia is a rare entity, and physical signs, laboratory results, and symptoms are not always helpful in diagnosis. Preoperative diagnosis of Amyand's hernia is not straightforward, and is generally an incidental finding during surgery. Imaging modalities, including ultrasound, can be very useful for making this rare diagnosis.

Pulmonary Hyalinizing Granuloma Mimicking Metastatic Lung Cancer.

Pulmonary hyalinizing granuloma is a very rare benign condition, which usually manifests as solitary and sometimes as multiple pulmonary nodules. Deposition of immune complexes in the lung parenchyma due to hypersensitivity reactions is implicated in the etiology of pulmonary hyalinizing granuloma. A 59-year-old female patient who presented to our clinic with complaints of chest pain and cough had bilateral, multiple, and rounded lesions with regular margins suggesting metastatic lung disease. A transthoracic needle biopsy of the nodule was performed in the left pulmonary anterior segment. Biopsy showed no malignancy. Since no diagnosis was made by the biopsy, the patient underwent a video-assisted thoracic surgery. The wedge biopsy reported pulmonary hyalinizing granuloma. We aimed to present the diagnosis and treatment stages of our patient who was diagnosed with pulmonary hyalinizing granuloma in the light of literature review.

Atypical Fryns syndrome: clinical, radiological and pathological findings.

Fryns syndrome is an autosomal recessive hereditary disease, including abnormal facies, small thorax with widely spaced hypoplastic nipples, distal limb and nail hypoplasia, and diaphragmatic hernia with pulmonary hypoplasia. The aim of the present report is to increase awareness of Fryns syndrome and its association with rare abnormalities such as cecal duplication cyst, horseshoe kidney and butterfly vertebra. We report a male 20-day-old baby with congenital diaphragmatic hernia (CDH), horseshoe kidney, butterfly vertebra, cleft palate, distal finger hypoplasia, left inguinal hernia, typical facial appearance for Fryns syndrome, and cecal duplication cyst. Fryns syndrome is the one of the most common syndromes associated with congenital diaphragmatic defect (CDH), reported in up to 10% of patients with CDH. Although no eye abnormality was seen in our patient, other findings were similar to the other typical diagnostic findings, with the exception of cecal duplication cyst and some other defects not defined before.
