Predictive Ability of the Combination of White Blood Cell and C Reactive Protein Levels for Infections Following Laparoscopic Hysterectomy.

OBJECTIVE: In the present retrospective study, we evaluated potentially predictive factors and determined receiver operating characteristic (ROC) curve cut-off values for effective detection of patients at higher risk of re-hospitalization due to postoperative infection after total laparoscopic hysterectomy. MATERIALS AND METHODS: We included 168 patients who had undergone laparoscopic hysterectomy. Data were collected from medical records. Patients were classified into non-infection (n = 161) and infection (n = 7) groups based on whether they developed fever after hospital discharge. We evaluated factors conventionally known to affect postoperative infection in general, and values of white blood cell (WBC) and C-reactive protein (CRP) determined on postoperative days 1 and 3-5. RESULTS: There were significant differences in WBC 3-5 days postoperatively (WBC POD3-5) (p = 0.049), CRP 3-5 days postoperatively (CRP POD3-5) (p = 0.018) and CRP POD3-5 × WBC 1 day postoperatively (WBC POD1) (p = 0.002). Area under the ROC curves for CRP POD3-5 and CRP POD3-5 × WBC POD1 were 0.81 and 0.84, and cutoffs were 4.46 mg/dL and 46885.5, respectively. CONCLUSION: If CRP POD3-5 or CRP POD3-5 × WBC POD1 is high, the physician should be alert to postoperative infection, and the patient should be under careful management and supervision.

Adenocarcinoma in situ or early-stage cervical cancer is a risk factor for preterm delivery after cervical conization: a multicenter observational study.

OBJECTIVE: Pregnancy after conization is associated with a high risk of preterm delivery. However, because risk factors for preterm delivery after conization remain unknown, we conducted a multicenter observational study to investigate risk factors associated with preterm delivery. METHODS: We selected patients who had previously undergone conization and reviewed medical records from 18 hospitals in cooperation with Keio University School of Medicine between January 2013 and December 2019. Women were classified as nulliparous and primiparous, and a multiple logistic regression analysis was performed to evaluate the relative contributions of the various maternal risk factors for preterm delivery (i.e. delivery before 37 gestational weeks). RESULTS: Among 409 pregnant women after conization, 68 women delivered preterm (17%). The incidence of nulliparity (p = .014) was higher and a history of preterm delivery (p = .0010) was more common in the preterm delivery group than in the term delivery group. Furthermore, the proportion of women diagnosed with adenocarcinoma in situ (AIS) and cervical cancer in the preterm delivery group was higher than that in the term delivery group (p = .0099 and .0004, respectively). In multiple regression models in nulliparous women, cervical cancer or AIS (Odds ratio [OR]: 4.16, 95% CI: 1.26-13.68, p = .019) and a short cervix in the second trimester (OR: 13.41, 95% CI: 3.88-46.42, p < .0001) increased the risk of preterm delivery. Furthermore, a history of preterm delivery (OR: 7.35, 95% CI: 1.55-34.86, p = .012), cervical cancer or AIS (OR: 5.07, 95% CI: 1.24-20.73, p = .024), and a short cervix in the second trimester (OR: 4.29, 95% CI: 1.11-16.62, p = .035) increased the risk of preterm delivery in the multiple regression models in primiparous women. CONCLUSION: Pregnant women who previously underwent conization are at risk for preterm delivery. The histological type of AIS and cervical cancer was evaluated as a risk factor for preterm delivery. KEY MESSAGESPrior preterm delivery, presence of a short cervix, and cervical cancer or AIS were predictors of preterm delivery after conization.The depth of conization in cervical cancer or AIS group was significantly larger than that in the CIN group.

Ageing impairs restoration of endometrial blood flow impedance after laparoscopic myomectomy in infertile women with uterine fibroids.

The aim of this study was to evaluate temporal changes in endometrial blood flow after laparoscopic myomectomy (LM). Nineteen infertile women with uterine fibroids who underwent LM were included. The uterine radial artery resistance index (RA-RI) and recovery index were measured before and at 1 week and 3 months after LM. The median RA-RI at 1 week but not 3 months after LM was significantly higher than before. The median recovery indexes at 1 week and 3 months after LM were 14.3% and 1.3%, respectively. Although there was no significant correlation between the patient's age and recovery index at 1 week (r = 0.28, p = .24) after LM, a moderately significant correlation was observed at 3 months (r = 0.54, p = .002). In conclusion, the endometrial blood flow after LM changed over time, and recovery of blood flow was negatively correlated with patient age.IMPACT STATEMENTWhat is already known on this subject? Uterine blood flow is important for wound healing after myomectomy, but no studies have evaluated endometrial blood flow after myomectomy.What do the results of this study add? The endometrial blood flow impedance of RA-RI increased after LM and returned to before surgery at 3 months postoperatively. RA-RI recovery index negatively correlated with patient age.What are the implications of these findings for clinical practice and/or further research? The changes in endometrial blood flow impedance after myomectomy suggest that endometrial blood flow may be involved in wound healing at the enucleation site. The impairment of endometrial blood flow recovery after myomectomy due to increased age may provide a rationale for individualised wound healing after myomectomy. The measurement of endometrial blood flow may be useful in personalising the assessment of the waiting period for pregnancy after myomectomy.

Relationship between temporal changes of endometrial blood flow impedance during natural and hormone replacement cycles and prediction of pregnancy during vitrified-warmed embryo transfer.

AIM: This study aimed to examine the relationship between the temporal changes in endometrial blood flow impedance during natural and hormone replacement therapy (HRT) cycles and clinical outcomes of vitrified-warmed embryo transfer (ET). METHODS: This retrospective observational cohort study included 60 women, 28 with natural, and 32 with HRT cycles, who underwent vitrified-warmed ET. Uterine radial artery resistance index (RA-RI) was measured during the natural and HRT cycles at the following time points: early follicular phase, day of the human chorionic gonadotropin injection during a natural cycle or day of progesterone administration during an HRT cycle, and day of ET. RESULTS: The clinical pregnancy rates of the natural and HRT cycles were 32.1% and 34.4%, respectively. The RA-RI at the early follicular phase was significantly lower in the pregnant group than in the nonpregnant group with natural but not HRT cycles (p = 0.04). The odds ratio for pregnancy was 0.70 (95% confidence interval [CI], 0.52-0.95) when the RA-RI value at the early follicular phase was increased by 0.01 in the natural cycle. With the natural cycle, the area under the receiver-operating characteristic curves for the RA-RI at the early follicular phase with a threshold of 0.68 was 0.75 (95% CI, 0.57-0.93), and the positive and negative predictive values were 0.53 (95% CI, 0.37-0.59) and 0.92 (0.74-0.99), respectively. CONCLUSION: RA-RI at the early follicular phase might be an effective and useful tool for deciding between natural or HRT cycles for vitrified-warmed ET.

Clinical usefulness of serum levels of soluble fms-like tyrosine kinase 1/placental growth factor ratio to rule out preeclampsia in women with new-onset lupus nephritis during pregnancy.

Measurement of the soluble fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio may be clinically useful to discriminate systemic lupus erythematosus (SLE) from preeclampsia. Here, we present a pregnant woman with new-onset SLE with hypertension, with the measurement of the sFlt-1/PlGF ratio during pregnancy. A 31-year-old Japanese nulliparous woman, who had been diagnosed with idiopathic thrombocytopenic purpura at 10 years, had a systolic blood pressure of 120 mmHg and was negative for proteinuria at 12+1 weeks. Since her blood pressure increased to 159/86 mmHg with 3+ proteinuria at 25+4 weeks, preeclampsia was suspected. Deterioration of the kidney function (creatinine: 0.58 mg/dL at 24+6 weeks to 0.83 mg/dL at 33+6 weeks) necessitated cesarean section at 33+6 weeks. After delivery, she still showed increased creatinine and proteinuria. Therefore, she was transferred to a nephrology specialist in a tertiary center and was finally diagnosed with SLE with lupus nephritis class IV-G(A) (diffuse lupus nephritis). The serum levels of sFlt-1 and the sFlt-1/PlGF ratio, which are usually elevated in preeclampsia, were within normal reference ranges at 27+6, 28+1, and 28+6 weeks of gestation, although the serum levels of PlGF were slightly lower than the normal reference range. In conclusion, measurement of the sFlt-1/PlGF ratio may be clinically useful to discriminate lupus nephritis from preeclampsia.

Combination of microwave endometrial ablation and postoperative dienogest administration is effective for treating symptomatic adenomyosis.

AIM: Menorrhagia and dysmenorrhea are common symptoms. Uterine adenomyosis is one of the causes of menorrhagia and dysmenorrhea. These symptoms often decrease the quality of life in women. Microwave endometrial ablation (MEA) is a recently developed procedure that enables endometrial ablation. Dienogest has long been used to suppress endometrium development and reduce adenomyosis-related dysmenorrhea. However, some cases could be resistant to dienogest. In this study, we evaluated the efficacy of a combination of MEA and postoperative dienogest in reducing adenomyosis-related dysmenorrhea and menorrhagia. METHODS: Ten patients with hormone treatment-resistant symptomatic adenomyosis underwent MEA and were administered oral dienogest after the procedure. The primary endpoints were reduction in pain recurrence and anemia. The secondary endpoint was a change in the adenomyosis lesion and its symptomatic recurrence. RESULTS: Statistically significant improvements were seen in the visual analog scale score and hemoglobin levels in women post-treatment. The difference in myometrial thickness pre- and post-MEA was statistically significant. There were no cases of symptomatic recurrence. CONCLUSION: The combination of MEA and postoperative dienogest is useful for treating uterine adenomyosis with menorrhagia and dysmenorrhea.

Activated phosphoinositide 3-kinase δ syndrome presenting with gut-associated T-cell lymphoproliferative disease.

A 13-year-old boy was admitted to our hospital because of persistent diarrhea, abdominal pain, and bloody stools. The patient had experienced repeated hospitalizations for the treatment of respiratory infections since early childhood. Colonoscopic and pathological studies led to a diagnosis of gut-associated T-cell lymphoproliferative disease (T-cell LPD). Laboratory data showed T-lymphocytopenia (492/µl), increased serum IgG levels (1,984 mg/dl), and low serum antibody titers for specific pathogens. Combined immunodeficiency accompanied by T-LPD suggested the diagnosis of activated PI3Kδ syndrome (APDS). Genetic analyses identified a heterozygous mutation of the PIK3CD gene (c.1573 G to A p.Glu525Lys). Although prednisolone and cyclosporine therapy has controlled the T-cell LPD, this patient awaits allogeneic hematopoietic cell transplantation to achieve a complete cure of his APDS.
