Isthmocele correction: resectoscopic, laparoscopic or both?

Background

An isthmocele is a myometrial defect in the site of the caesarean scar. In symptomatic women with abnormal uterine bleeding and secondary infertility, surgical correction can be considered. Most authors advocate that when there's a residual myometrium ≥ 3mm it can be corrected through resectoscopic approach and when < 3mm the treatment should be laparoscopic, eventually guided by diagnostic hysteroscopy. Both these techniques have important limitations; therefore, the authors propose combining both techniques, in the same procedure, in order to overcome them.

Objectives

To demonstrate the advantages of a surgical technique for correction of an isthmocele using both resectoscopic and laparoscopic resection.

Material and Methods

A stepwise demonstration of the technique with narrated video footage.

Main outcome measures

Intraoperative data and outcomes in the patient's follow-up.

Results

One month after the surgery the patient was asymptomatic, reporting a resolution of the uterine abnormal bleeding, and the ultrasound showed a full correction of the isthmocele.

Conclusion

A combination of resectoscopic and laparoscopic resection, in correcting bigger isthmoceles, is a good option to fully excise all the fibrotic tissue.

Learning objective

This video aims to demonstrate the benefits of using a technique combining resectoscopic and laparoscopic resection for correcting larger isthmoceles.

The Effect of Diabetes and Prediabetes on Anti-tuberculosis Treatment Outcomes: A Multi-center Prospective Cohort Study

BACKGROUND

It is unclear whether diabetes or prediabetes affect unfavorable treatment outcomes and death in people with tuberculosis (PWTB).

METHODS

Culture-confirmed drug-susceptible PWTB, enrolled in Regional Prospective Observational Research in Tuberculosis (RePORT)-Brazil between 2015-2019 (n=643) were stratified based on glycemic status according to baseline glycated hemoglobin. Unfavorable TB outcome was defined as treatment failure or modification, recurrence or death; favorable outcome was cure or treatment completion. We corroborated the findings using data from PWTB reported to the Brazilian National System of Diseases Notification (SINAN) during 2015-2019 (n=20,989). Logistic regression models evaluated associations between glycemic status and outcomes.

RESULTS

In both cohorts, in univariate analysis, unfavorable outcomes were more frequently associated with smoking, illicit drug use and HIV infection. Diabetes, but not prediabetes, was associated with unfavorable outcomes in the RePORT-Brazil (adjusted Relative Risk [aRR]: 2.45, p<0.001) and SINAN (aRR: 1.76, p<0.001) cohorts. Furthermore, diabetes was associated with high risk of death (during TB treatment) in both RePORT-Brazil (aRR:2.16, p=0.040) and SINAN (aRR:1.93, p= 0.001).

CONCLUSION

Diabetes was associated with an increased risk of unfavorable outcomes and mortality in Brazilian PWTB. Interventions to improve tuberculosis treatment outcomes in persons with diabetes are needed.

[Analysis of the demand for detection of SARSCoV-2 in a health area of Spain]

OBJECTIVE

Since the discovery of the SARS-CoV-2 virus, the polymerase chain reaction technique (RT-PCR) has become the fundamental method for diagnosing the disease in its acute phase. The objective is to describe the demand-based series of RT-PCR determinations received at a Microbiology Service at a third-level reference hospital for a health area for three months spanning from the onset of the epidemic by SARS-CoV-2.

METHODS

A retrospective analysis of the total of the RT-PCR requested in the Microbiology Service analyzed from 02/25/2020 to 05/26/2020 (90 days) has been carried out. They have been grouped by epidemiological weeks and by the petitioner service. A descriptive analysis was carried out by age, gender and number of requests for each patient. In the tests carried out, a confidence level of 95% (p <0.05) was considered significant.

RESULTS

A total of 27,106 requests was received corresponding to 22,037 patients. Median age 53.7 (RIC 40.9-71.7) years, women: 61.3%. Proportion of patients with any positive RT-PCR: 14%. Of the total requests for RT-PCR, positive 3,710. Week 13 had the highest diagnosis performance (39.0%). The primary care has been the service thar has made the most requests (15,953). Patients with 3 or more RT-PCR: 565, of them, 19 patients had a positive result after previously having a negative one.

CONCLUSIONS

Requests have been increasing depending on the evolution of the epidemic. The RT-PCR has a high diagnostic performance in the phases of highest contagiousness and / or transmissibility of the virus.

Viral Load in Spanish HIV patients: trends since the introduction of HAART

The aim of this study is to describe trends in the percentage of samples with undetectable HIV viral load in Spain after the implementation of HAART. A descriptive observational study of HIV-VL measurements carried out in the microbiology department of the Hospital Clínico Universitario de Valladolid (HCUV) was conducted over a 9-year period (1996-2004). Regarding the trend over the study period, the 30-39 years age group accounted for most of the samples, although the percentage decreased from 65.5% to 59.6% over the study period. In contrast, the 40-49 years group increased from 9.1% to 14.5%. The preponderance of men, with percentages above 70%, was observed during the whole period. Although the purpose of this treatment is to maintain undetectable viral loads, since 1999 more than 60% of nonfirst samples had detectable levels. Based on the results of the VL trend among HIV/AIDS patients observed in this study, a large number of patients maintain elevated detectable VL years after HAART was implemented. Although different factors may be the cause of this and should be delimited in future studies, the phenomenon observed demonstrates the usefulness of monitoring VL and analyzing its time trend to gain further knowledge about the therapeutic results and care of HIV patients as a whole, also serving as the basis for corrective measures.

Comparison of the efficacy and tolerability of solifenacin succinate with or without previous use of trospium chloride

Overactive bladder syndrome (OBS) is described as urinary urgency with or without incontinence, usually with increased daytime frequency and nocturia in the absence of another identifiable pathological process. Nowadays and despite other alternative therapies, the mainstay of OBS is still the pharmacological approach, mainly with anti-muscarinic drugs. To compare the efficacy of a 30-day solifenacin succinate (5 mg OD) treatment with or without previous medication with trospium chloride, a prostective open, two-arm, parallel group study was conducted for 5 weeks in 40 patients with OBS. The primary endpoint was patient self-assessment of improvement after 30 days of medication. Secondary endpoints included the reduction of the daily number of voids and urgency or involuntary leakage episodes. Adverse reactions and therapeutic stoppage were also evaluated. To be included in the trospium chloride treatment group, patients were required to have been treated with such drug for 1 to 6 months before the present study. Evaluation and efficacy assessment were accomplished using a 3-day bladder diary and an urgency severity scale (USS). Safety assessment was done by recording all the patients' complaints after starting medication. A total of 40 patients were enrolled for this study, 19 without previous medication and 21 who had already tried trospium chloride. Two patients from the non-previous medication group were excluded. Globally, there was a statistically significant reduction for the USS (2.73-->1.73), the daily number of voids (9.5-->7.0), of urgency episodes (9.1-->4.0) and of involuntary leakage episodes (3.6-->1.0) over the 24 h. Six patients had no improvement, four from the previous trospium chloride group and two from the non-previous medication group. Three patients reported side effects, two cases of dry mouth and one case of constipation. One patient dropped out of the treatment due to an unspecified intolerance. Solifenacin succinate 5 mg seems to be effective concerning patients' self-assessment of improvement and decrease in the mean number of daily voids, urgency episodes and incontinence episodes. This was reported both in patients who have already been medicated with trospium chloride and those who have never taken any kind of medication. Regarding side effects, solifenacin is quite well-tolerated in both groups.
