Intra-amniotic digoxin for feticide between 21 and 30 weeks of gestation: a prospective study.

OBJECTIVE: Intra-amniotic injection of digoxin is a well-known method for feticide before inducing a termination of pregnancy (TOP) at 17-24 weeks of gestation. Information on its effectiveness when administered after 24 weeks of gestation is limited. This study evaluated the efficacy of intra-amniotic digoxin injection for inducing fetal demise within 18-24 hours, at 21-30 weeks of gestation, and its safety. DESIGN: Prospective cohort study. SETTING: Tertiary university medical centre. POPULATION: Women at 21-30 weeks of gestation with a singleton pregnancy, admitted for TOP. METHODS: Intra-amniotic injection of 2 mg of digoxin was performed 1 day before medical TOP. Fetal heart activity was evaluated by ultrasound for 18-24 hours after the injection. Serum digoxin level and maternal electrocardiogram (ECG) were evaluated 6, 10, and 20 hours after injection. MAIN OUTCOME MEASURE: Frequency of successful fetal demise. RESULTS: Fifty-nine women participated in the study. The mean gestational age was 24+2  weeks (range 21+0 -30+0 ), with 29 (49.2%) beyond 24+0  weeks of gestation. Fetal cardiac activity arrest was achieved in 55/59 cases (93.2%). Normal maternal ECG recordings were noted in all cases. Mean serum digoxin levels 6 and 10 hours after injection were in the therapeutic range (1.3 ± 0.7 ng/l and 1.24 ± 0.49 ng/l, respectively) and below the toxic level (2 ng/l). Extramural delivery following digoxin did not occur. There were no cases of chorioamnionitis. CONCLUSION: Intra-amniotic digoxin for feticide at 21-30 weeks of gestation in a singleton pregnancy appears effective and safe before TOP at advanced gestational ages. TWEETABLE ABSTRACT: This study shows that feticide by intra-amniotic digoxin injection at 21-30 weeks of gestation appears effective and safe.

Preoperative sleep quality predicts postoperative pain after planned caesarean delivery.

BACKGROUND: Severe post-caesarean pain remains an important issue associated with persistent pain and postpartum depression. Women's sleep quality prior to caesarean delivery and its influence on postoperative pain and analgesic intake have not been evaluated yet. METHODS: Women undergoing caesarean delivery with spinal anaesthesia (bupivacaine 12 mg, fentanyl 20 µg, morphine 100 µg) were evaluated preoperatively for sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire (PSQI 0-5 indicating good sleep quality, PSQI 6-21 poor sleep quality). Peak and average postoperative pain scores at rest, movement and uterine cramping were evaluated during 24 h using a verbal numerical pain score (VNPS; 0 indicating no pain and 100 indicating worst pain imaginable), and analgesic intake was recorded. Primary outcome was peak pain upon movement during the first 24 h. RESULTS: Seventy-eight of 245 women reported good sleep quality (31.2%; average PSQI 3.5 ± 1.2) and 167 poor sleep quality (68.2%; average PSQI 16.0 ± 3.4; p < 0.001). Women with poor sleep quality had significantly higher peak pain scores upon movement (46.7 ± 28.8 vs. 36.2 ± 25.6, respectively; p = 0.006). With multivariable logistic regression analysis, poor sleep quality significantly increased the risk for severe peak pain upon movement (VNPS ≥70; OR 2.64; 95% CI 1.2-6.0; p = 0.02). DISCUSSION: A significant proportion of women scheduled for caesarean delivery were identified preoperatively as having poor sleep quality, which was associated with more severe pain and increased analgesic intake after delivery. The PSQI score may therefore be a useful tool to predict increased risk for acute post-caesarean pain and higher analgesic requirements, and help tailor anaesthetic management. SIGNIFICANCE: Multiple studies have evaluated predictors for severe acute pain after caesarean delivery that may be performed in a clinical setting, however, sleep quality prior to delivery has not been included in predictive models for post-caesarean pain. The PSQI questionnaire, a simple test to administer preoperatively, identified that up to 70% of women report poor sleep quality before delivery, and poor sleep quality was associated with increased post-caesarean pain scores and analgesic intake, indicating that PSQI could help identify preoperatively women at risk for severe pain after caesarean delivery.

Severe pain during local infiltration for spinal anaesthesia predicts post-caesarean pain.

BACKGROUND: Quantitative sensory testing (QST) measures response to painful stimuli and has been used to predict post-caesarean pain. Pain reported upon intravenous cannulation was shown to predict epidural analgesic use and pain intensity during labour. We hypothesized that pain intensity reported by women upon local anaesthesia injection (ILA) for spinal anaesthesia may predict acute pain after caesarean delivery (CD). METHODS: In a prospective observational trial, 229 women undergoing elective CD under spinal anaesthesia were enrolled. Using standardized script before ILA, women received ILA (lidocaine 1% 2.5 mL via 25 G needle), and provided an ILA score after the injection [verbal numeric pain scale (VNPS); 0-100]. Demographic data, average, peak pain (at rest, with movement and uterine cramping) and analgesic requests were recorded for the first 24 h. RESULTS: Fourteen percent of women experienced severe pain (VNPS ≥70) upon ILA. Good correlation was noted between ILA and pain scores at rest and upon mobilization during the 24 h following surgery (average resting pain r = 0.529, p < 0.001, average pain at mobilization r = 0.483, p < 0.0001). Severe acute postoperative pain (VNPS ≥70) was predicted by severe ILA pain with a sensitivity of 91.6% and specificity of 93.3%. CONCLUSION: This is the first study evaluating a clinical measure to predict post-caesarean pain. Our main findings were that 14% of women experience severe pain upon ILA, which was associated with increased pain during the first 24 h.

Pubertal-related changes in hypothalamic-pituitary-adrenal axis reactivity and cytokine secretion in response to an immunological stressor.

Pubertal development is marked by profound changes in stress reactivity. For example, following a brief stressor, such as foot shock, ether inhalation or restraint, prepubertal rats display a prolonged adrenocorticotrophic hormone (ACTH) and corticosterone response that takes twice as long to return to baseline compared to adults. Pubertal-related differences in the recovery of the hormonal stress response following a more protracted systemic stressor, such as an immunological challenge, have not yet been investigated. Moreover, it is unclear whether an immunological stressor leads to a differential cytokine response in animals before and after pubertal maturation. To examine these issues, we used a single injection of lipopolysaccharide (LPS; 0.1 mg/kg) to induce a hormonal stress and innate immune response and measured plasma ACTH, corticosterone, and the pro-inflammatory cytokines interleukin (IL)-1ß and IL-6 in prepubertal and adult male rats 0, 2, 4, 6, 8, or 24 h after LPS exposure. In a follow-up experiment, we assessed neural activation, as indexed by FOS immunohistochemistry, in the paraventricular nucleus of the hypothalamus (PVN) in prepubertal and adult males 0, 4, 8, or 24 h after a 0.1 mg/kg injection of LPS. By contrast to the prolonged response observed in prepubertal animals following a variety of acute stressors, we found that corticosterone and IL-6 responses induced by LPS recover toward baseline faster in prepubertal compared to adult rats. Along with these different peripheral responses, we also found that LPS-induced neural activation in the PVN of prepubertal animals showed a faster return to baseline compared to adults. Together, these data indicate that prepubertal and adult animals react in distinct ways, both peripherally and centrally, to an immunological stressor.

Hydrometrocolpos--diagnostic and therapeutic dilemmas.

Congenital distal vaginal obstruction is a rare condition, usually asymptomatic until menarche, thus often diagnosed only during puberty. Hydrometrocolpos is caused by such an obstruction, only when reasonable amounts of fluid are secreted from the mucosal lining of the genital tract. This presentation may be symptomatic and already diagnosed early in life, even during the perinatal period. There are various causes of congenital vaginal obstruction, and according to their etiology, surgical procedures may be either simple or more complicated. Timing of the surgical procedure for opening the obstruction is a dilemma. We suggest postponing the definite procedure to the menarche, when hematocolpos (accumulation of blood in the vagina) will develop, but before the further development of hematometra (accumulation of blood in the uterine cavity). This will cause stretching of the obstructed segment, will enable correct diagnosis, facilitate the procedure, and eventually minimize the complications. However, if the vaginal obstruction in neonates or in childhood is symptomatic, as in the described case, aspiration of the fluid and temporary release of the symptoms should be the optimal choice, followed by a final surgical correction latter in life.

Luteinized thecoma associated with sclerosing peritonitis--conservative surgical approach followed by corticosteroid and GnRH agonist treatment--a case report.

BACKGROUND: Luteinized thecoma of the ovary associated with sclerosing peritonitis is a rare tumor that has no standard definitive treatment regimen. CASE: A 25 year-old patient diagnosed with luteinized thecoma and sclerosing peritonitis in the omentum. The patient received high dose corticosteroids (IV Hydrocortisone 500 mg/d) and GnRH agonist (IM Leuprolide 3.75 mg) in order to achieve ovarian suppression and relief of the clinical peritonitis. She was re-admitted two weeks later due to bowel obstruction which was treated conservatively. The steroid regimen was continued by oral intake for 5 weeks with complete remission of the peritonitis related symptoms. The bilateral enlarged ovarian tumor-like solid was the prominent finding in consecutive ultrasound exams with no decrease in size despite of the above mentioned protocol. Thus, the patient was re-operated for exploration and biopsies of the ovary and the pathology report showed no evidence of remnant disease in the ovary, or in the peritoneum. Completing follow-up of 15 months since the last operation, the patient is asymptomatic. She conceived spontaneously and currently is in her 24th week of a normal pregnancy. CONCLUSION: This is the first case report in the English literature of a successful medical conservative treatment of a young patient with luteinized thecoma associated with sclerosing peritonitis that led to complete relief of the symptoms and allowed fertility preservation.

Comparison of hydrodistillation and ultrasonic solvent extraction for the isolation of volatile compounds from two unifloral honeys of Robinia pseudoacacia L. and Castanea sativa L.

A comparative study of ultrasound-assisted extraction (USE) with the mixture pentane:ether (1:2) and hydrodistillation (HD) with the same trapping mixture is presented for the isolation of volatile compounds from two unifloral honeys of Robinia pseudoacacia L. and Castanea sativa L. All HD isolates contained many thermally derived artefacts (especially phenylacetaldehyde with lower percentages of furfural, cis- and trans-linalool oxides and others). USE method gave the most representative profile of all honey volatiles (without artefacts). In addition, USE enabled extraction of low molecular weight semivolatile markers (especially benzoic, vanillic and phenylacetic acids) that were not extracted by HD. In this regard, low percentage of benzoic acid (0.7-7.4%), vanillic acid (0.0-1.6%) and phenylacetic acid (0.5-4.1%) was determined in Rp USE extracts, while Cs USE extracts contained phenylacetic acid (20.2-23.5%) as the major constituent with low percentage of benzoic acid (2.5-5.5%).

Hemorrhagic corpus luteum is associated with ovarian edema.

BACKGROUND: Most cases of ovarian edema are thought to result from intermittent ovarian/adnexal torsion. This study describes how, in some cases, this etiology was ruled out even though the edema was unexplained. STUDY OBJECTIVE: To evaluate the association between ovarian edema and hemorrhagic corpus luteum. SETTING: Department of gynecology in an urban medical center. PARTICIPANTS: Five patients admitted to the department of gynecology with a sonographic diagnosis of ovarian edema of unexplained etiology. RESULTS: Laparoscopy performed on three of five patients in whom a diagnosis of unexplained ovarian edema revealed hemorrhagic corpus luteum and ovarian edema. The remaining two patients displayed typical sonographic imaging of hemorrhagic corpus luteum and ovarian edema and they were managed expectantly. The affected ovaries were between 4.8 and 10 times larger than the unaffected ovaries. During follow-up, the affected ovaries returned to their normal size and appearance. CONCLUSIONS: Hemorrhagic corpus luteum can cause ovarian edema without interrupting the blood flow supply. The outcome of expectant management without any surgical intervention is the gradual disappearance of the ovarian edema in these patients and the return of ovaries to a normal sonographic appearance.

Hydrosalpinx with adnexal torsion in an adolescent virgin patient--A diagnostic dilemma: case report and review of the literature.

Hydrosalpinx is one of the predisposing factors of adnexal torsion. However, because the incidence of hydrosalpinx in adolescent virgin patients is very rare, it may cause diagnostic dilemma, leading sometimes to suboptimal treatment. We present the case of an 18-yr-old female, not sexually active, presenting with acute lower right abdominal pain. The working diagnosis was of a simple ovarian cyst, so aspiration was performed. Abdominal symptoms reoccurred and sonography revealed a large hemorrhagic cystic mass adjacent to an edematous right ovary. The patient was referred to immediate laparoscopy due to suspected right adnexal torsion. On laparoscopy, the right adnexa was twisted three times causing an edematous ovary with a hematosalpinx. Detorsion was performed. Five weeks later, transabdominal ultrasound reviled normal bilateral ovaries and the hematosalpinx disappeared. In conclusion, hydrosalpinx, although very rare in adolescence, must be considered in the differential diagnosis. Aspiration in such cases is not the treatment of choice and moreover, it may cause complications.

Application of comparative genomic hybridization technique for detection of chromosomal aberrations in benign cystic teratoma.

Benign cystic teratoma, also known as dermoid cyst, is the most common of all ovarian neoplasms accounting for 10%-20% of all ovarian cysts. Most have a normal 46,XX karyotype. Less than 2% can undergo malignant transformation. By using the comparative genomic hybridization technique on nine benign ovarian cysts we were able to show two cases with chromosomal aberrations not seen before in dermoid cysts but known to be involved in malignant ovarian tumors. We speculate that these are the tumors carrying the potential for malignant transformation.

Primary peritoneal borderline tumor. A case report and review of the literature.

A case report and review of the literature of a primary peritoneal borderline tumor is presented. A patient with primary peritoneal borderline tumor diagnosed by elevated of serum CA-125 and asymptomatic pelvic cysts, two years after laparotomy due to mullerian cysts, is discussed.

Replication pattern of the p53 and 21q22 loci in the premalignant and malignant stages of carcinoma of the cervix.

BACKGROUND: Loss of replication synchrony during the S-phase of the cell cycle has been shown to be associated with aneuploidy in malignant cells. METHODS: The replication pattern of cervical cells obtained from normal patients and from patients with preinvasive and invasive carcinoma of the cervix was evaluated. The fluorescence in situ hybridization technique was applied to Papanicolaou smear slides using p53 and 21q22 loci. Asynchrony was determined by the presence of one single and one set of double dots in the same cell. RESULTS: The rate of asynchrony in low grade squamous intraepithelial lesions was not significantly different from that of normal controls. However, the rate of asynchrony was significantly higher in the high grade squamous intraepithelial lesions and even higher in the invasive carcinoma. CONCLUSIONS: The authors believe these results reflect impairment of the replication control of homologous loci and that this phenomenon may be correlated to the phenotype of the tumor.
