Ultrasound in the Diagnosis of Pediatric Distal Radius Fractures: Does it Really Change the Treatment Policy? An Orthopedic View.

Background: Distal radius fractures are the most common pediatric fractures, increasing in number in recent decades. Although simple bi-planar radiographs are sufficient for diagnosis, wrist ultrasonography has been popularized in recent years for fracture detection, mostly because of the concern about children's radiation exposure. Despite its availability and diagnostic accuracy, ultrasound has not gained widespread acceptance and popularity among orthopedic surgeons. We asked about the reasons for its lack of acceptance as a diagnostic tool by orthopedic surgeons, and its failure to be incorporated into diagnostic algorithms. Material and methods: We reviewed the latest articles concerning the use of ultrasound in the diagnosis of pediatric distal radius fracture. Data extraction was performed from each study with a focus on the following items: the specialty field of the authors, number of patients, number of fractures, mean age of the patients, and the gold standard method of diagnosis. Results: Nine studies concerning the diagnostic accuracy of ultrasound in detecting distal radius fractures in children were included in the review. The most common field of practice of the authors was emergency medicine. Only two studies had an orthopedic surgeon among their authors. All studies employed X-ray imaging as the gold standard method. All studies were designed as prospective trials without randomization of patients. Generally, there was no independent blinded reviewer for the interpretation of ultrasound and X-ray images. Conclusions: Most studies were completed by emergency medicine physicians, without involving an orthopedic surgeon. Ultrasound evaluation was undertaken primarily by emergency medicine physicians with little experience. These studies were not randomized controlled trials, and knowledge of the history and clinical presentation of the subjects could have led to information bias. The relatively low number of included patients and lack of follow-up examinations were other limitations. As a result, we believe that ultrasound has not proven to be a suitable substitute for conventional X-ray imaging in the detection of pediatric distal radius fractures. We propose X-ray evaluation as the clinical gold standard method for pediatric wrist fractures.

Comparison of intramuscular progesterone with oral nifedipine for treating threatened preterm labor: A randomized controlled trial.

Background: Threatened preterm labor (TPL) is the leading cause of hospitalization during pregnancy. Tocolytic agents are the primary therapeutic options for TPL. The aim of this study is to compare intramuscular progesterone with oral nifedipine as a tocolytic agent. Methods: This randomized controlled trial was carried out in a teaching hospital (Shahid Akbarabadi) in Tehran, Iran, from December 2011 to November 2012. Three hundred and fifteen singleton pregnant women aged >18 yrs at 26-34 weeks' gestation with the diagnosis of threatened preterm labor (TPL) were randomly received either intramuscular progesterone or oral nifedipine for tocolysis. Maternal and neonatal outcomes were then compared between the two interventions. P value less than 0.05 was considered statistically significant. IRCT registration number of this study is IRCT201112198469N1 Results: The success rate of progesterone and nifedipine in treating TPL were 83% and 82.7%, respectively. There was no significant difference between the two interventions with regard to gestational age at delivery, type of delivery, the time interval until the delivery, birth weight, NICU admission rate and hospital stays. Progesterone administration was associated with lower duration of NICU stay as compared with nifedipine (0.33±0.77 days vs.1.5±3.2 days, p<0.05). None of the two drugs caused any major side effects. Conclusion: Single dose intramuscular progesterone is as effective as oral nifedipine in treating TPL. It also significantly reduces the NICU stay.

Can combination of hysterosalpingography and ultrasound replace hysteroscopy in diagnosis of uterine malformations in infertile women?

BACKGROUND: Müllerian anomalies are associated with infertility. Hysteroscopy as the gold standard for evaluating Müllerian anomalies is an invasive, expensive and risky procedure which requires enough experience. Transvaginal sonography (TVS) and hysterosalpingography (HSG) are less invasive procedures, but there is little known about the accuracy of these tests. The aim of this study was to evaluate the accuracy of the combination of TVS and HSG with hysteroscopy as the gold standard. METHODS: Medical records of infertile women who were undertaken all three diagnostic modalities were reviewed to analyze their sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS: Ninety-nine infertile women were assessed with a mean±SD age of 29.1±6.47 years, mean±SD duration of themarriage of 8.9±10.28 years, and mean±SD duration of infertility of 5.6± 4.16 years. The sensitivity, specificity, PPV, and NPV of TVS were 98.55%, 30%, 76.4%, and 90%, respectively. HSG had a sensitivity of 95.6%, specificity of 60%, PPV of 84.62%, and NPV of 85.71%.When both modalities were combined, the sensitivity, specificity, PPV, and NPV were 94.2, 66.67, 86.67, and 83.33%, respectively. The diagnostic accuracy of single TVS, HSG or combined techniques was statistically similar that was equal to 77.7, 84.8 and 85.8 % respectively. CONCLUSION: The accuracy of combination of two diagnostic modalities, 2D TVS and HSG is not higher than HSG alone for assessing uterine malformation in infertile women.

Floating Index Metacarpal Associated with Multiple Carpometacarpal Fracture-Dislocations: a Case Report.

The floating metacarpal bone is a result of simultaneous fracture-dislocation of both carpometacarpal and metacarpophalangeal joints. This rare entity may be associated with other hand injuries. Here we present a floating index metacarpal with concomitant 3rd-5th carpometacarpal fracture-dislocations. Excellent functional short-term result was achieved after open metacarpopha langeal reduction and closed carpometacarpal reduction and percutaneous pinning.

Advantages of Recombinant Follicle-Stimulating Hormone over Human Menopausal Gonadotropin in Intrauterine Insemination: A Randomized Clinical Trial in Polycystic Ovary Syndrome-Associated Infertility.

BACKGROUND: Various gonadotropin preparations have been used for ovarian stimulation in intrauterine insemination (IUI). The purpose of the current study was to compare human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (rFSH) combined with clomiphene citrate (CC) in IUI cycles for polycystic ovary syndrome-associated infertility. METHODS: In this prospective trial, couples prepared for IUI cycles were randomly allocated either to receive CC and rFSH (group A, n = 132) or CC and hMG (group B, n = 144) for ovarian stimulation. Outcomes including rates of clinical pregnancy, miscarriage, ovarian hyperstimulation syndrome, multiple pregnancy, cancellation and live birth were compared. RESULTS: The duration of gonadotropin therapy was shorter and total doses of gonadotropins was lower in the rFSH group. The number of stimulated follicles reaching >17 mm diameter was comparable between groups, but the mean follicular diameter was significantly higher in the rFSH group. The endometrium was also significantly thicker at the time of human chorionic gonadotropin administration in the rFSH group. However, pregnancy outcomes, including the rates of clinical pregnancy, ongoing pregnancy, live birth, miscarriage, ovarian hyperstimulation syndrome and cancellation, were similar between groups. CONCLUSION: IUI cycles in which rFSH is administered may result in shorter duration of treatment, a lower total gonadotropin dose and better follicular and endometrial characteristics on the day of human chorionic gonadotropin injection. © 2015 S.

In vitro fertilization outcome following embryo transfer with or without preinstillation of human chorionic gonadotropin into the uterine cavity: a randomized controlled trial.

BACKGROUND: Intrauterine injection of human chorionic gonadotropin (hCG) at embryo transfer (ET) has been shown to improve the outcome of assisted reproductive techniques. The aim of this study was to confirm previous findings. METHODS: In this randomized controlled trial, 483 infertile women who were candidates for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) for the first time were randomly assigned to receive an intrauterine injection of 500 IU hCG or placebo (tissue culture media) before ET. The main outcome measures were implantation and clinical pregnancy rates. RESULTS: Both the hCG-treated group (n = 240) and control group (n = 243) were similar at baseline in terms of demographic and obstetrical characteristics. There were significant differences between the two groups regarding the implantation rate (23.6 vs. 12.2%, p < 0.001), pregnancy rate (54.6 vs. 35.8%, p < 0.001), clinical pregnancy rate (50 vs. 32.1%, p < 0.001), ongoing pregnancy rate (15.3 vs. 9.2%, p < 0.001) and live delivery rate (14.3 vs. 8.4%, p < 0.001). The rate of fertilization and abortion rates were not statistically different. CONCLUSION: Intrauterine injection of hCG before ET improves implantation and pregnancy rates and may be considered an adjuvant in IVF/ICSI.

The reliability and validity of the persian version of sinonasal outcome test 22 (snot 22) questionnaires.

BACKGROUND: The quality of life (QOL) is an important indicator for disease-severity classification and outcome measurement in obtaining treatment sinonasal diseases. The sinonasal outcome test 22 (SNOT 22) questionnaire has been introduced as the best specific sinonasal instrument for QOL measurement. OBJECTIVES: To prepare a valid and reliable Persian language version of SNOT 22 questionnaire. PATIENTS AND METHODS: After forward and backward translation of the original version of SNOT 22 questionnaire from English to Persian, a group of patients with nasal septal deviation who need septal surgery and another group of healthy volunteers answered the Persian version of the questionnaire. The responsiveness rate, validity (Pearson correlations and differential validity) and reliability (internal consistency and test-retest reliability) of the 22 items of the questionnaire was calculated. P value < 0.05 was considered significant. RESULTS: Thirty adults with nasal septal deviation need surgical correction and 30 healthy volunteers were included (mean age 30.4 ± 7.1 vs. 33 ± 6.7, P value = 0.148). The questionnaire was introduced to subjects two times with a two-week-period gap. Total responsiveness rate for 22 items was more than 97%. The total Cronbach's Alfa coefficient was 0.898 (ranging 0.890-0.903). The Pearson correlations were 0.85 and 0.96 for patients and healthy volunteers, respectively. The mean total score were 25.6 ± 13.3 (range 6-52) and 7.6 ± 9.1 (range 0-45) in patients and healthy volunteers, respectively (P < 0.0001). The subscales scores were also significantly different between two groups. CONCLUSIONS: The Persian version of SNOT 22 questionnaire is a valid and reliable instrument for accessing sinonasal diseases in Persian-speaking people.
