Hysterectomy may have an effect on the pelvic floor. Here, we evaluated the rates and risks for pelvic organ prolapse (POP) surgeries and visits among women with a history of hysterectomy for benign indication excluding POP.
In this retrospective cohort study 3582 women who underwent hysterectomy in 2006 were followed until the end of 2016. The cohort was linked to the Finnish Care Register to catch any prolapse-related diagnoses and operation codes following the hysterectomy. Different hysterectomy approaches were compared according to the risk for a prolapse, including abdominal, laparoscopic, laparoscopic-assisted vaginal and vaginal. The main outcomes were POP surgery and outpatient visit for POP, and Cox regression was used to identify risk factors (hazard ratios [HR]).
During the follow-up, 58 women (1.6%) underwent a POP operation, of which a posterior repair was the most common (n = 39, 1.1%). Outpatient visits for POP symptoms occurred in 92 (2.6%) women of which posterior wall prolapses (n = 58, 1.6%) were the most common. History of laparoscopic-assisted vaginal hysterectomy were associated with risk for POP operation (HR 3.0, p = 0.02), vaginal vault prolapse operation (HR 4.3, p = 0.01) and POP visits (HR 2.2, p < 0.01) as compared to the approach of abdominal hysterectomy. History of vaginal deliveries and concomitant stress urinary continence operation were associated with the risk for a POP operation (HR 4.4 and 11.9) and POP visits (HR 3.9 and 7.2).
Risk for POP operations and outpatient visits for POP symptoms in hysterectomized women without a preceding POP seems to be small at least 10 years after hysterectomy. History of LAVH, vaginal deliveries and concomitant stress urinary incontinence operations increased the risk for POP operations after hysterectomy. These data can be utilized in counseling women considering hysterectomy for benign indication.

BACKGROUND: Combined spinal epidural anesthesia (CSEA) is commonly performed in cesarean deliveries. However, it is difficult to perform in obese parturients because of positioning challenges. The aim of this study was to compare the effect of different approaches to CSEA under the guidance of ultrasound.
METHODS: One hundred obese patients (BMI ≥ 30 kg/m2) who underwent elective cesarean section were randomly enrolled. Patients were assigned to a median approach group and a paramedian approach group randomly. Clinical characteristics were compared between groups. First-attempt success rate, the median positioning time and total operation time, ultrasonic predicted anesthesia puncture depth, actual puncture depth, anesthesia adverse reactions, complications after anesthesia, and patients\' satisfaction with the epidural puncture were recorded.
RESULTS: The first-attempt success rate was significantly different between the two groups [92% (46/50) vs. 76% (38/50), P  =  0.029]. The median positioning time and total operation time in the paramedian approach group were higher than those in the median approach group (227.7 s vs. 201.6 s, P  =  0.037; 251.3 s vs. 247.4 s, P  =  0.145). The incidence of postanesthesia complications in the paramedian approach group was significantly lower than that in the median approach group (2% vs. 12%, P  =  0.026), and patient satisfaction was higher in the paramedian approach group than in the median approach group (P  =  0.032).
CONCLUSIONS: The ultrasound-guided paramedian approach for CSEA is time-consuming, but it can effectively improve the success rate of the first puncture, reduce the incidence of anesthesia-related adverse reactions, and improve patient satisfaction.
BACKGROUND: This study was registered with the Chinese Clinical Trial Registry (ChiCTR1900024722) on July 24, 2019.

UNASSIGNED: Although rigorous efforts have substantially decreased the malaria burden through decades, it still threatens the lives of millions of children. Development of an effective vaccine can provide important approach in malaria control strategies. Unfortunately, development of an effective vaccine for falciparum malaria has been hindered by the extreme complexity of malaria parasite biology, complex and diverse parasite genomes, and immune evasion by the parasites as well as the intricate nature of the parasites infection cycle. The aim of this review was to discuss the different approaches to malaria vaccine development until now.
UNASSIGNED: Scientific databases, including MEDLINE (via PubMed) and SCOPUS were searched up to 30 Jan 2017 and the articles regarding malaria vaccine development were taken into examination.
UNASSIGNED: Several strategies for malaria vaccine development including pre-erythrocytic vaccines, antibody-based subunit vaccines, vectored vaccines, whole sporozoite vaccines, genetically Attenuated parasites and sporozoite subunit vaccine, erythrocytic vaccines, sexual stage vaccine, transmission-blocking vaccine as well as synthetic peptides and conjugate vaccine has been introduced. However, the success has been limited thus far.
UNASSIGNED: Although development of malaria vaccine over the past 70 year has been continued, the discovery, development, and licensing of a malaria vaccine formulation, which meets safety, affordability, accessibility, applicability, and efficacy has not yet been achieved.

The aim of this study was to evaluate clinical outcomes of different approaches to patients with proximal descending thoracic aneurysm (DTA) involving the distal arch.
From January 2002 to December 2016, 229 consecutive patients with proximal descending aorta aneurysm involving the distal arch underwent surgery using different approaches: total arch and DTA replacement via sternotomy (TAR group; n = 98), hemiarch and DTA replacement via thoracotomy (DTR group; n = 84), or hybrid arch repair (HAR group; n = 47). We retrospectively evaluated the outcomes of the 3 groups with a mean follow-up duration of 60.2 months.
The in-hospital mortality rate was 3.1% (3/98) in the TAR group, 11.9% (10/84) in the DTR group, and 4.3% (2/47) in the HAR group (P = .04). The TAR group had a lower incidence of stroke (3.1%, 3/98) compared with the DTR (13.1%, 11/84) and HAR (10.6%, 5/47) groups (P = .03). The overall survival rate at 10 years was 82.8% ± 5.6% for the TAR group, 61.0% ± 8.6% for the DTR group, and 55.9% ± 9.0% for the HAR group (vs DTR [P = .03] and HAR [P < .01]). The freedom from composite of aortic events at 10 years was 75.6% ± 8.1% in the TAR group, 43.6% ± 14.9% in the DTR group, and 31.1% ± 11.5% in the HAR group (P < .01).
The sternotomy approach showed better outcomes in terms of operative mortality, stroke, and long-term survival compared with the thoracotomy or hybrid approaches. This study suggests that the sternotomy approach is the superior option for patients with proximal descending aneurysm involving the distal arch.

The objective of this study is to analyse the complications of orbital decompression in Graves\' orbitopathy. The clinical records of 946 patients who had been operated on with orbital decompression for Graves\' orbitopathy were reviewed and the intra- and post-operative complications with minimum follow-up of six months were analysed. An extensive review of the literature was carried out to compare results. In the case-series reported here the most frequent complications were: wasting of the temporal region (100%) in patients operated on using a coronal approach; permanent hypoesthesia of V2 (13%) and V1 (8%) in patients operated on with an upper eyelid incision. In only one patient was a total monolateral lesion of V2 reported. The most severe complications consisted in reduction of visual acuity in 5 patients, and CSF leak with cerebral complications in 2 patients, who were operated on with a non-endoscopic endonasal approach. Three patients had intra-operative haemorrhages and 3 patients had post-operative haemorrhages requiring further surgical intervention. The incidence of symptomatic sinusitis/mucoceles was 0.75%. In conclusion, orbital decompression carried out with endoscopic endonasal technique and via transpalpebral accesses appears to be associated with a low incidence of complications. Knowledge of the causes of the possible complications in the different surgical approaches can definitely help to reduce their incidence.
L’obiettivo di questo studio è analizzare le complicanze della decompressione orbitaria in pazienti affetti da oftalmopatia Basedowiana. Abbiamo analizzato 946 pazienti sottoposti a decompressione orbitaria per orbitopatia di Graves e le complicanze intra- e post-operatorie con un follow-up minimo di 6 mesi. Abbiamo eseguito inoltre un’estesa revisione della letteratura per comparare i risultati. Nel nostro studio le più frequenti complicanze sono state: atrofia della regione temporale (100%) nei pazienti sottoposti a decompressione con approccio coronale; ipoestesia permanente di V2 (13%) e V1 (8%) in pazienti sottoposti a decompressione con approccio transpalpebrale superiore. Un solo paziente ha avuto una lesione totale monolaterale di V2. Le complicanze più gravi sono state la riduzione dell’acuità visiva, che si è verificata in 5 pazienti, e la perdita di liquido cerebrospinale con complicanze cerebrali, verificatesi in 2 pazienti, entrambi operati con approccio endonasale non endoscopico. 3 pazienti hanno avuto un’emorragia intraoperatoria mentre 3 pazienti un’emorragia postoperatoria che ha richiesto un secondo intervento chirurgico. L’incidenza delle sinusiti/mucoceli sintomatici è stata dello 0,75%. In conclusione abbiamo evidenziato come la decompressione orbitaria eseguita con tecnica endoscopica endonasale e con accessi transpalpebrali sia una procedura chirurgica con una bassa incidenza di complicanze. La conoscenza delle cause delle possibili complicanze nei differenti approcci chirurgici può sicuramente aiutare a ridurre la loro incidenza.

Our objective is to analyze and observe the different administration routes of parecoxib sodium pretreatment on the behavioral improvement of rats with neuropathic pain to provide the preclinical data of parecoxib sodium on neuropathic pain treatment. 30 SD rats were randomly divided into five groups, including model group, sham operation group, intrathecal injection group (IT group), intraperitoneal injection group (IP group), and perineural infiltration group (PI group). The rats in model group and three parecoxib sodium pretreatment groups received spinal nerve ligation (SNL). Heat pain test and 50 % paw mechanical withdrawal threshold test (50 % PMWT) were use to assess the responses after parecoxib sodium pretreatment. 50 % PMWT results of right foot in five groups had no statistical difference (P > 0.05); 50 % PMWT results of left and right feet in three parecoxib sodium pretreatment groups were obviously higher than SNL group at different time points, which was statistically different (P < 0.05); in comparison with three pretreatment groups, the data of left foot in IT group were obviously higher than PI group and IP group, and the comparison among three groups had significant difference (P < 0.05). However, the data of right foot had no significant difference among three groups (P > 0.05). Paw thermal withdrawal latency (PTWL) results of left and right feet in five groups had no significant difference before surgery (P > 0.05); after the establishment of neuropathic model, PTWL results in five groups were significantly decreased; however, PTWL results of left and right feet at 3 days after surgery in IT group were significantly higher than the two other pretreatment groups (P < 0.05); PTWL results of left and right feet at 7 and 14 days after surgery had no significant difference. Parecoxib sodium pretreatment can effectively improve the behaviors caused by neuropathic pain, and intrathecal injection is the most effective route of administration.
