Human Engineered Heart Tissue Patches Remuscularize the Injured Heart in a Dose-Dependent Manner

Supplemental Digital Content is available in the text.

Human engineered heart tissue (EHT) transplantation represents a potential regenerative strategy for patients with heart failure and has been successful in preclinical models. Clinical application requires upscaling, adaptation to good manufacturing practices, and determination of the effective dose.

Giant cervical myoma associated with urinary incontinence and hydroureteronephrosis

Cervical leiomyomas compromise fewer than 5% of all uterine leiomyomas. Cervical myomas exacerbates surgical difficulties, such as poor operative field, difficult suture repairs, and blood loss. When performing myomectomy for cervical myomas, care must be taken to avoid injuries to neighboring structures in the pelvic cavity.These structures include the bladder in front of the cervix, the rectum behind the cervix, and the uterine arteries and ureters on both sides. Myomectomy for cervical myoma is empirically difficult and frequently problematic. The authors report a case of giant cervical myoma presenting with urinary incontinence.

Effects of postpartum uterine curettage on maternal well-being in severe preeclamptic patients

PURPOSE

We assessed the effect of postpartum uterine curettage on maternal recovery time in severe preeclamptic patients.

METHOD

Fifty-six pregnant women with the diagnosis of severe preeclampsia in their third trimester were enrolled in the study. Uterine curettage was performed in the early postpartum period on 31 randomly selected patients and curettage was not performed in the remaining 25 patients. Prepartum mean arterial pressure (MAP) values, quantitative platelet counts, presence of proteinuria tested semiquantatitively, lactic dehydrogenase (LDH), aspartate transferase (AST), alanine transferase (ALT), and uric acid levels were determined.

FINDINGS

In the group that underwent curettage, we observed a faster drop in the mean arterial pressures monitored at two-hour intervals, especially after the sixth postpartum hour (p < 0.05). Average urine output recorded at four-hour intervals in the postpartum period was significantly higher in the curettage group compared to the non-curettage group (p < 0.05). The difference in the platelet counts of both groups was not significant at the 12th postpartum hour, however, at 24 hours, platelet counts in the curettage group were higher. In the postpartum period at the 12th and 24th hours there was no difference between the two groups with regard to LDH, AST, and ALT values (p > 0.05).

RESULTS

In our study we have observed that uterine curettage performed in the postpartum period had favorable effects on blood pressure, platelet count, and urinary output and also helped in faster recovery from severe preeclampsia. We, therefore, consider that postpartum uterine curettage is useful for patients with severe preeclampsia that require faster recovery.

Evaluation and importance of asymptomatic bacteriuria in pregnancy

OBJECTIVES

This study was undertaken to determine the incidence of asymptomatic bacteriuria (ASB) during pregnancy and its prevalance in the three trimesters.

SUBJECTS AND METHODS

One hundred and ten pregnant women in their first trimester attending the antenatal outpatient clinic with no urinary tract complaints were included in the study. After perineal cleaning, urine samples were obtained from all patients for culture and microscopic evaluation. Approximately 1 ml urine was sampled using the mid-stream catch technique. Patients with bacterial counts over 100,000 with the mid-stream catch technique were considered to have asymptomatic bacteriuria. Patients fulfilling the criteria for bacteriuria were treated with either penicillin or cephalosporine for one week, depending on the in-vitro sensitivity test results.

RESULTS

ASB rate in the study group was 8.1%. E. coli was isolated as the pathogenic organism in 77.77% of the cases with ASB. ASB was found to be more frequent in patients over age 25 and the average age of pregnant women with ASB was 29.89 +/- 5.80 (p < 0.05). Average duration of gestation in the group with ASB was 28.11 +/- 2.26 weeks. ASB rate in the group age 35 and over was 22.22% (p < 0.05). ASB was diagnosed in nine patients; one of these patients was in the first trimester, two were in the second trimester, and six in the third trimester. Clustering in the third trimester was found to be statistically significant (p < 0.05).

CONCLUSION

ASB distribution in the first, second, and third trimesters was 0.9%, 1.83%, and 5.6%, respectively. There was a significant relationship between advanced maternal age and incidence of ASB. Women with no bacteriuria in their initial examination in the first trimester developed bacteriuria in the later trimesters. We, therefore, suggest that it would be prudent to screen pregnant women for bacteriuria in the second and third trimesters.
