Abstract
Background: Various therapeutic options such as calcitonin have been suggested for patients with low bone density, despite uncertain efficacy in most patients. C-telopeptide of type I collagen (CTX) is a new bone marker used for the assessment of bone resorption. The aim of this study was to evaluate the therapeutic effects of nasal spray calcitonin in women with osteopenia via serum CTX and other laboratory tests.
Methods: We conducted a self controlled clinical trial in 2009 on 105 women of menopausal age diagnosed in Baqiyatallah Hospital Clinic with osteopenia based on a bone mineral density score of 1.5 SD lower than peak bone mass. The patients were assigned to receive nasal spray calcitonin (200 IU/day), calcium (1000 mg/day) and Vit-D (400 IU/day) for 6 months. Serum CTX and other laboratory parameters were measured before and after the treatment. The data were analyzed by SPSS, version 17, using t-tests and a P<0.05 was considered statistically significant.
Results: Fifty-two patients completed the study and the mean CTX level decreased significantly from 3.10±2.03 to 2.61±1.82 pmol/lit (P<0.001), but total serum levels of PTH, Ca, AST, ALT and Alkaline Ph decreased insignificantly.
Conclusion: It seems that nasal spray of calcitonin is significantly effective in preventing disease progression and treatment of low bone density by inhibiting bone tissue resorption indicated by CTX although further studies with larger samples sizes and inclusion of control groups are warranted.

Abstract
Background: Previous investigations have shown that pregnancy-associated plasma protein-A (PAPP-A) levels are associated with adverse pregnancy outcomes including intrauterine growth restriction (IUGR) fetuses as well as preterm delivery. The aim of this study was to determine the rate of preterm delivery in women with low PAPP-A and at intermediate risk for chromosomal abnormalities in the first trimester screening.
Methods: A total of 137 women who underwent Down syndrome screening between 11 to 14 weeks of gestation were studied from September 2011 to September 2013 at Perinatal Care Clinic, Imam Khomeini Hospital, Ahvaz, Iran. From those, 52 patients had low PAPP-A. Inclusion criteria were singleton pregnancies, at 11 to 14 weeks of gestation, at intermediate risk for Down syndrome (risk in 1:101 to 1:1000). The intermediate risk was estimated based on maternal parameters, maternal serum markers (PAPP-A and β-hcG), and nuchal translucency (NT) using fetal medicine foundation (FMF), UK) software. The power of the study was 90%. The sample size was estimated based on prevalence of preterm delivery in pregnancies with low PAPP-A in the first trimester screening. Patients were followed-up until delivery to observe pregnancy outcomes. We evaluated the variables such as level of PAPP-A, outcomes of delivery, age, β-hCG, and gestational age.
Results: Among 137 normotensive pregnant women at intermediate risk for Down syndrome, 52 cases (38%) had low PAPP-A (<0.4 MoM). Of 52, 14 cases (27%) had preterm delivery. None of our patients had pregnancy related or non related diabetes, preeclampsia, or chromosomal anomalies. 45 cases (86%) from 52 patients were equal or less than 35 years, while 7 patients were more than 35 years. Among 52 followed-up patients, 48 patients (92.4%) were at low-intermediate risk (risk in 1:251 to 1:1000), and 4 cases (7.6%) were at high-intermediate risk (risk in 1:101 to 1:250).
Conclusion: We found high frequency of preterm delivery in pregnant women with low PAPP-A level at the first trimester screening. Hence, this group of patients needs special and early preventive management. Furthermore, we suggest that future researches to be conducted with larger sample size and also cervix length measurement to be included.

Abstract
Background: More than one-third of women develop headaches in the first week after childbirth. Approximately 75% are benign primary headaches such as migraines or tension headaches. Others are secondary and include headaches of vascular origin or from hypertensive disease, infection, space-occupying lesions and dural puncture. Postdural Puncture Headache (PDPH) is a common and annoying complication of spinal anesthesia, especially in cesarean section. This study compares the impress of an Atropine-Neostigmine mixture and Ondansetron on Post Spinal Puncture Headaches in Cesarean sec.
Methods: This triple-blinded controlled randomized clinical trial was conducted on 60 pregnant women candidates for cesarean section under spinal anesthesia, that was carried out from May 2021 to August 2021 at Behshti Medical and Education Center affiliated with Isfahan University of Medical Sciences. The study was approved by the Ethics Committee of the University (IR.MUI.REC.1400.009) and informed consent was obtained from the patients/legal guardians. This clinical trial was registered at www.irct.ir with identification code IRCT 20160307026950N39.
People were randomly assigned into three groups. A mixture of neostigmine (20 micrograms per kilogram) and atropine (10 micrograms per kilogram) in the first group and 4 mg of Ondansetron in the second group and a similar volume of normal saline in the control group were administered before surgery. Patients were followed up for headaches up to seven days after surgery. The severity of the headache was measured using the VAS scale. One-way analysis of variance (ANOVA) and non-parametric equivalent, Kruskal-Wallis, chi-square test, and repeated measure test were used to measure the relationship between the variables.
|
Results: Analysis of the data did not show a significant difference between the three groups in terms of headache severity (P=0.788), headache duration, (P=0.723), the time elapsed from lumbar puncturing to the occurrence of the first headache (P=0.653), and the frequency of attempts for correct spinal tap (P=0.685).
Conclusion: none of our considered interventions had a noticeable impress on preventing or reducing PDPH in Cesarean section.
