Two successful natural pregnancies in a patient with severe uterine prolapse: A case report

<p>Abstract</p> <p>Introduction</p> <p>Uterine prolapse is a common gynecologic condition that is rare during or before pregnancy. We report an exceptional case of two pregnancies in a totally prolapsed uterus.</p> <p>Case presentation</p> <p>A 36-year-old Caucasian woman with a history of uterine prolapse presented with pregnancy. A vaginal pessary was applied to keep her uterus inside the pelvis after manual reposition. The pessary was removed at the 24th week. The gravid uterus persisted in the abdominal cavity because of its increased volume.</p> <p>Conclusion</p> <p>Our case shows that pregnancy during uterine prolapse is possible and that careful assessment is required to prevent complications during delivery. According to our experience, an elective caesarean section near term could be the safest mode of delivery.</p

Electrochemical behaviour of AISI 316 austenitic stainless steel in acidic media containing chloride ions

The electrochemical behaviour of AISI 316 austenitic stainless steel (SS) was investigated in deaerated hydrochloric and sulphuric acid solutions using the open-circuit potential, cyclic voltammetric and chronoamperometric techniques. Enhanced corrosion of steel samples occurred with bigger HCl concentrations, as the potential range of passivity was shortened and both the pitting (Epit) and the protection potentials (Eprot) became less noble. Conversely, the SS electrodes exhibited a greater corrosion resistance in solutions containing sulphuric acid of the same concentration. The aggressive effect of chloride ions towards steel corrosion was also investigated through controlled additions of NaCl to both electrolytic media and the analysis of the corresponding effects on the shape of the voltammetric curves. Chronoamperometric measurements run by setting different potential values to steel electrodes allowed the determination of the induction time for pit initiation, and the rates of pit nucleation and pit growt

Inhibitory action of non toxic compounds on the corrosion behaviour of 316 austenitic stainless steel in hydrochloric acid solution: comparison of chitosan and cyclodextrin

The inhibitory action of two non toxic organic compounds, chitosan and hydroxypropyl-beta-cyclodextrin (HP-β-CD), against the corrosion of 316 austenitic stainless steel in acidic chloride solutions was studied. Weight loss and electrochemical tests show that the inhibitory action increases with concentration of the organics, though the effect is greater with chitosan than with HP-β-CD for a given concentration. These compounds act as anodic inhibitors (by forming an adsorbing film on the metal surface and blocking the active corrosion sites), whereas the cathodic half-reaction is not significantly affected. The highest inhibition efficiency attained in 0.1 M HCl solution was 76% by using chitosan

October 2013 Tucson pulmonary journal club: tiotropium Respimat

No abstract available. Article truncated at 150 words. Tiotropium, a long-acting inhaled anticholingeric bronchodilator, is commonly used to prevent COPD exacerbations (1). Tiotropium is available as a dry powder (HandiHaler) or aqueous solution (Respimat). Direct comparisons of the two formulations are lacking. Prior post-hoc analyses suggest that that Respimat may be more efficacious than HandiHaler (2) but it may also increase the risk of death, particularly among those with cardiac dysrhythmias (3-6). The two were recently compared in a large randomized, double-blind, parallel trial of once daily treatment with Respimat (2.5 µg or 5 µg) or HandiHaler (18 µg).[add REF here] Inclusion criteria included a COPD diagnosis, a 10 pack year smoking history, and post-bronchodilator FEV1/FVC ratio ≤ 0.70 and FEV1 ≤ 70% of predicted. Major exclusion criteria included a myocardial infarction within past 6 months, hospitalization for Class III or IV heart failure, or unstable or life-threatening arrhythmia requiring new treatment within the previous 12 months.

8772 The Impact of Acute Urinary Retention Volume on Postoperative Urinary Dysfunction Following Robotic Sacrocolpopexy

Study Objective: Sacrocolpopexy (SCP) for pelvic organ prolapse is typically performed with a midurethral sling (MUS) to treat or prevent postoperative stress urinary incontinence (SUI). A known complication is the development of postoperative urinary dysfunction, namely obstructed voiding, chronic urinary retention (CUR) and eventual sling release. This study aims to investigate whether the degree of acute urinary retention (AUR) is predictive of longer-term sequelae. Design: Retrospective case control study. Setting: Academic-affiliated community hospital. Patients or Participants: All patients (n=708) undergoing a robotic SCP with transobturator MUS placement by a single urogynecologist between January 2012 and March 2022 stratified by their post-void residual bladder volumes (PVRBV) were included in this study. Interventions: Patients were grouped by their degree of PVRBV: ≤150mL (n=397), \u3e150 and ≤300mL (n=111), \u3e300 and ≤450mL (n=84), and \u3e450mL (n=116). Measurements and Main Results: Higher volumes of AUR had a statistically significant increase in the percentage chance risk of CUR. (6.3%, 16.2%, 10.7%, 14.7%, p\u3c0.05). A non-statistically significant distribution was observed between PVRBV and requirement for eventual sling release (3%, 1.8%, 0%, 6%, p=0.08). There were no differences in other long term postoperative sequelae amongst variable degrees of acute PVRBV including urinary symptoms, need for postoperative medications or return to the emergency department or hospital readmissions. Patients with greater PVR volumes had lower body mass index (28.7, 27.7, 27.2, 26.8 kg/m2, p\u3c0.05). Other demographic variables were similar amongst groups. Conclusion: Increasing BMI has a protective effect from developing CUR. Higher PVRBV in excess of 150mL were associated with a greater propensity for CUR. This had a trend toward requiring sling release and/or revision. Future studies are necessary to determine whether the degree of AUR is related to the procedure or pre-existing bladder dysfunction
