Uterine myomata and outcome of assisted reproduction

The aim of this work was to study the effect of uterine myomata on the implantation rate and outcome in in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Among 406 patients, 51 (12.6%) were found to have uterine corporeal myomata. Twelve patients were excluded from the study as they had large myomata, submucous myomata or intramural myomata encroaching on the cavity. These patients were advised to have myomectomy before being enrolled in the IVF/ICSI programme. The remaining patients (n = 39) were sorted according to the number, site and size of the myomata as assessed by transvaginal sonography. Three patients had more than one myoma. Most of the myomata were subserous (72.7%) and the mean diameter of the myomata was 3.5 +/- 0.9 cm. A control group (n = 367) was chosen with normal uteri and no history of uterine reconstruction surgery. The mean age of myoma patients was 34.7 +/- 3.6 years as compared to 34.0 +/- 4.4 years in the control group. The age, period of infertility, body mass index, duration and number of human menopausal gonadotrophin ampoules needed for stimulation, oestradiol levels, number of oocytes retrieved and the fertilization rate were not significantly different in the myoma patients compared to the control group. Fifteen myoma patients (38.5%) subsequently showed one or more pregnancy sacs on ultrasonography of which three (20%) spontaneously aborted during the first trimester and two (13.3%) had preterm labour, as compared to 123 (33.5%), 19 (15.5%) and nine (7.3%) respectively, among the control group (P = 0.27, 0.33 and 0.21). In conclusion, uterine corporeal myomata, not encroaching on the cavity and <7 cm in mean diameter, do not affect the implantation or miscarriage rates in IVF or ICSI.

Propionibacterium as a cause of postneurosurgical infection in patients with dural allografts: report of three cases

OBJECTIVE AND IMPORTANCE: Although Propionibacterium acnes is a common inhabitant of human skin, it is an uncommon pathogen in postoperative infections. We report three cases of postoperative wound infection/osteomyelitis caused by P. acnes. CLINICAL PRESENTATION: Three patients underwent craniotomy for a supratentorial meningioma and had a dural allograft at the time of closure. The patients presented several weeks after surgery with clinical evidence of a wound infection. INTERVENTION: All patients were diagnosed with P. acnes infection and treated for this pathogen with appropriate antibiotics. The bone flap was removed in two patients. After antibiotic therapy, all patients demonstrated no further evidence of infection. CONCLUSION: To our knowledge, this is the first published report of P. acnes infection in patients with a dural substitute. The source of infection cannot be confidently ascertained; however, two patients had strains of P. acnes from one brand of graft, which were indistinguishable by pulsed field gel electrophoresis typing.     

Assessment of thyroidal "C" cell secretion in osteoporotic girls with Turner''s syndrome. Basal and calcium-stimulated levels of total calcitonin, extractable calcitonin and katakalcin

Osteoporosis is a common finding in Turner's syndrome. To test the hypothesis that calcitonin deficiency may contribute to bone mineral loss in Turner's syndrome, we studied basal and calcium-stimulated (2 mg/kg body weight in 5 min) levels of total calcitonin, extractable calcitonin and katacalcin in 15 girls with Turner's syndrome and osteoporosis. Fifteen age-matched healthy girls were studied as controls. Both basal calcitonin (total and extractable) and katacalcin values were not significantly different in patients with Turner's syndrome in comparison with those of the controls. The calcium stimulation test showed a similar "C" cell secretory reserve in both groups. The calculation of delta CT/delta iCa of total and extractable calcitonin and delta KC/delta iCa, which accounts for individual variations in serum ionized calcium increases, did not show any significant difference between girls with Turner's syndrome and controls. We conclude that calcitonin deficiency is not a causative factor of osteoporosis in girls with Turner's syndrome and that in this syndrome long-life estrogen deficiency does not impair "C" cell secretory activity.     

Prognostic value of motor evoked potentials elicited by multipulse magnetic stimulation in a surgically induced transitory lesion of the supplementary motor area: a case report

Surgery involving the supplementary motor area (SMA) places the patient at risk of transient motor deficit. To predict outcome in patients with early postoperative hypokinesis would be relevant to both the patient and the surgical team. A 15 year old girl with a large left thalamic tumour removed through a left transcallosal approach is described. Despite intraoperatively preserved muscle motor evoked potentials (mMEPs) from all limbs, elicited by multipulse electrical stimulation, she awoke with a right hemiplegia and mutism. On the first postoperative day, neurophysiological evaluation using a multipulse magnetic stimulation technique, with a train of four magnetic stimuli, confirmed the presence of mMEPs from the hemiplegic right limbs. Slight spontaneous motor activity of the right limbs and initial speech were seen later on the same day with dramatic improvement over subsequent days. It is concluded that multiple rather than single magnetic stimulation techniques may be needed to elicit mMEPs for an early postoperative differential diagnosis of SMA damage versus injury to the primary motor cortex or the corticospinal tract.     

Study protocol for a multisite randomized controlled trial of an internet and mobile‐based intervention for preventing and reducing perinatal depressive symptoms

Nearly 20% of women in the United States experience clinically significant depressive symptoms during pregnancy or the postpartum period. These women may benefit from easily accessible, nonpharmacologic, and inexpensive self‐management approaches, such as via internet and mobile‐based interventions, to prevent development of symptoms and/or intervene with current symptoms. This paper summarizes the research protocol of a nationally‐funded large‐scale randomized controlled study to evaluate “Mamma Mia,” a self‐guided program with 44 modules that women use throughout pregnancy to 6 months postpartum. The program contains a novel combination of components designed to enable women to enhance self‐efficacy, emotional self‐regulation, and perceived social support. The overall goal of this three‐arm longitudinal randomized controlled trial is to evaluate the effects and mechanisms of this self‐management approach in diverse women in the U.S. (n = 1950). Enrolled pregnant women will be randomly assigned to one of three groups: (1) “Mamma Mia” alone, which is self‐guided; (2) “Mamma Mia Plus” in which participants engage in the “Mamma Mia” modules plus receive brief guided support from a registered nurse; or (3) usual prenatal/postpartum care. The first specific aim is to evaluate effects by group on the primary outcome of interest, depressive symptoms, over time. The second aim is to evaluate effects by group on subjective well‐being, anxiety, and stress. Using a conceptual framework based upon Individual and Family Self‐Management Theory, the third aim is to evaluate possible mediators (self‐efficacy, emotion self‐regulation, perceived support) and possible moderators (e.g., race/ethnicity, type of healthcare clinician) of this self‐management approach.     

Cross‐sectional assessment of pain and physical function in skeletal dysplasia patients

Short stature skeletal dysplasia (SD) patients have orthopedic and neurologic complications causing significant pain and physical disability. We conducted a large cross‐sectional online survey in 361 people with short stature SD (>10 years) to describe pain prevalence, characteristics, and the relationship between pain and function. Chronic pain prevalence per Brief Pain Inventory (BPI) was 70.3%. Women reported more pain than men (73% vs 63% p = 0.04). Pain Severity Score (average of current, worst, least and average pain) averaged 3.3 ± 2, while the Pain Interference Score (with daily activities) averaged 3.4 ± 2.7 on a 10‐point scale. Per Bleck scale, 20.5% had little or no functional capacity. Increasing age and decreased ambulation independently predicted chronic pain. Chronic pain is prevalent in short stature SD patients and associated with poor physical function. Further study is required to clarify the temporal relationship among pain, function and treatments.
