Objective. Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS) are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power Doppler analysis.Methodology. A longitudinal study, with each subject acting as its own control was conducted between January 2010 and December 2012. Healthy volunteers with a history of heavy but cyclic and regular menstrual cycles were enrolled in the study. Ultrasonographic examination was performed before and after six months of LNG-IUS placement: uterine volume, endometrial thickness, and subendometrial and myometrial Doppler blood flow patterns have been evaluated.Results. A total of 32 women were enrolled out of 186 initially screened. At six months of follow-up, all subjects showed a reduction in menstrual blood loss; for analysis, they were retrospectively divided into 3 groups: normal cycling women (Group I), amenorrheic women (Group II), and women with prolonged bleedings (Group III). Intergroup analysis documented a statistically significant difference in endometrial thickness among the three groups; in addition, mean pulsatility index (PI) and resistance index (RI) in the spiral arteries were significantly lower in Group I and Group III compared to Group II. This difference persisted also when comparing—within subjects of Group III—mean PI and RI mean values before and after insertion.Conclusions. The LNG-IUS not only altered endometrial thickness, but—in women with prolonged bleedings—also significantly changed uterine artery blood flow. Further studies are needed to confirm these results and enable gynecologists to properly counsel women, improving initial continuation rates.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

We have determined the sites of action of endothelin-1 (ET) in the lamb pulmonary circulation. The influence of cyclooxygenase inhibition and baseline vasomotor tone on ET effects was also studied. Lungs of 14 lambs (6-9 wk of age, 12.1 +/- 0.6 kg body wt) were isolated and perfused with blood. Group I lungs (n = 5) were untreated, group II lungs (n = 5) were treated with indomethacin to inhibit cyclooxygenase, and group III lungs (n = 4) were treated with indomethacin and a thromboxane A2 analogue, U-46619, to elevate vasomotor tone. All lungs were perfused with constant flow in zone 3, with left atrial and airway pressures being 8 and 6 cmH2O, respectively. We measured pulmonary arterial pressure and, by the micropuncture servo-null method, pressures in 20- to 50-microns diameter subpleural venules, both before and after each dose of ET was infused (50, 100, 250, and 500 ng/kg). Group I lungs, with high baseline vasomotor tone, exhibited a biphasic response to ET; 50-100 ng/kg of ET dilated both arteries and veins, whereas 500 ng/kg of ET constricted both arteries and veins. In group II lungs with low vasomotor tone, all doses of ET caused constriction of arteries only. In group III lungs (indomethacin treated with elevated vasomotor tone), 50-100 ng/kg of ET caused dilation of arteries and veins, whereas 500 ng/kg of ET induced constriction, this time only in arteries. We conclude that ET has both dilator and constrictor effects in arteries and veins of isolated, perfused lamb lungs. ET-induced arterial and venous dilation is dependent on initial vasomotor tone but not on cyclooxygenase metabolites.(ABSTRACT TRUNCATED AT 250 WORDS)

Background/Aim. Elevation in adduction is the most common pattern of vertical strabismus, and it is mostly treated with surgery. The results of weaking of inferior oblique muscle are very changeable. The aim of this study was to evaluate binocular vision using sensory tests before and one and six months after the surgery. Methods. A total of 79 children were divided in two groups: the first, with inferior oblique muscle of overaction (n = 52), and the second with dissociated vertical deviation (DVD), and primary inferior oblique muscle overaction (n = 27). We tested them by polaroid mirror test (PMT), Worth test at distance and near, fusion amplitudes on sinoptofore, Lang I stereo test and Wirt-Titmus stereo test. We examined our patients before and two times after the surgery for vertical strabismus. Results. Foveal suppression in the group I was found in 60.5% of the patients before, and in 56.4% after the surgery. In group II Foveal suppression was detected in 64.7% of the patients before, but in 55.6% 6 months after the surgery with PMT. Worth test revealed suppression in 23.5% of the patients before, and in 40.7% after the vertical muscle surgery. Parafoveal fussion persisted in about 1/3 of the patients before the surgery, and their amplitudes were a little larger after the surgery in the group I patients. Lang I stereo test was negative in 53.9% before and 51.9% after the surgery in the group I, and in 48.2% of the patients before and after the surgery in the group II patients. Wirt-Titmus stereo test was negative in 74.5% of the patients before and in 72.9% after the surgery in the group I, but in the group II it was negative in 70.8% before and in 68.0% of the patients 6 months after the surgery. Conclusion. Binocular responses were found after surgery in 65.7% of the patients the group I and in 55.6% patients the group II. There was no significant difference between these two groups, but binocular responses were more often in the patients of the group I.

Introduction: Congenital malformations (CM) are most common in newborns and infants in the first year of life and require surgical correction in the first hours, days, months of life. Surgical interventions in severely ill babies with malformations can lead to catabolic stress, circulatory and respiratory disorders, metabolism shifts, water-electrolyte, protein, and acid-base status disorders. This study aimed to compare acid-base status in newborns and infants with congenital surgical pathology under different types of combined anesthesia.  Materials and methods: This retrospective study included 150 newborns and infants with CM who required surgery. The patients were divided into three groups based on types of provided anesthesia: inhalation by Sevoran (sevoflurane) and regional anesthesia (group I); inhalation of Sevoran and intravenous anesthesia by Fentanyl (group II); and intravenous combination of Fentanyl and 20% Sodium Oxybutyrate (group III). The analysis included: acid-base status, peripheral oximetry, and the need for an oxygen mixture inhaled by the patient. Results In group I, there was a significant reduction in partial tension of CO2 and increased pH from the pre-surgical status, at the time of induction of anesthesia, during the most painful, traumatic stage, and after surgery compared to group II and III. Peripheral O2 saturation was not critically reduced at all stages of observation except in babies of group I compared to group III at the stage of induction of anesthesia (97.79 ± 2.45 vs. 98.79 ± 1.63, p = 0.0194) and at the most painful period of surgery (96.29 ± 3.47 vs. 98.10 ± 2.47, p = 0.0368). In group I, newborns and infants required higher oxygen concentrations in the inhalation mixture. There was a significant difference in FiO2 between groups I and III during the most painful stage of surgery (0.47 ± 0.29 and 0.33 ± 0.2, p = 0.0071), and immediately after surgery (0.34 ± 0, 19 and 0.26 ± 0.13, p = 0.0246). Conclusion: Among the newborns and infants with CM requiring surgical intervention and combined anesthesia, the most substantial acid-base status changes were observed in the group where anesthesia was provided by Sevoran (sevoflurane) and regional anesthesia (Group I).

Background: As most of breast cancer patients are treated with Tamoxifen, different effects of this drug in patients should be evaluated since no such study is carried out in Bangladesh till date. Objective: The purpose of the present study was to evaluate sonographic changes of female genital organs in breast cancer patients treated with Tamoxifen and to correlate these changes with duration of Tamoxifen treatment and gynecological symptoms. Methodology: This randomized double-blind clinical trial was carried out in Delta Medical College Hospital, Dhaka, Bangladesh from May 2017 to April 2018 for a period of one (1) year. The participants were breast cancer patients which were divided into three groups named as group I patients. The patients of these group were on Tamoxifen therapy. The patients of group II were without Tamoxifen therapy. The patients of group III had completed Tamoxifen therapy. All participants underwent ultrasonography. Results: Patients receiving Tamoxifen therapy had significantly more thickened endometrium compared to other groups (26.6% in group I, 5% in group II and3% in group III). Similarly, abnormal sonographic findings and mean uterine volume were higher in group I compared to other two groups. Endometrial thickness and uterine volume showed significant positive correlation with duration of Tamoxifen therapy (p <0.0001). The endometrial thickness and uterine volume greatly increased after two years of Tamoxifen therapy while it was reverse in group III. Gynecological symptoms had no significant relations with sonographic abnormalities and thickened endometrium. Conclusion: Tamoxifen therapy is associated with increased endometrial thickness, uterine volume and abnormal sonographic findings, compared to patients without Tamoxifen or completing Tamoxifen therapy.

Background: The present study was conducted to assess the outcome of intrathecal analgesia in multiparous women undergoing vaginal delivery. Subjects and Methods: The present study was conducted among 80 multiparous women ages ranged 18- 40 years. All patients received 0.5 ml of intrathecal injection of 2.5 mg bupivacaine 0.5% and 1 ml dexamethasone 4 mg plus a 0.5 ml adjuvant. The adjuvants in group I patients were 100 μg morphine, 25 μg fentanyl in group II, 5 μg dexmedetomidine in group III and normal saline in group IV (control group). The primary and secondary outcome was the duration of pain relief, the analgesia onset time, the maximum level of sensory block, the visual analogue scale (VAS) was recorded. Results: The mean duration of analgesia in group I was 182.4 minutes, in group II was 170.5 minutes, in group III was 200.4 minutes and in group, IV was 140.2 minutes. The onset of analgesia was 3.9 minutes, 2.8 minutes, 2.7 minutes and 4.5 minutes in group I, II, III and IV respectively. S1 sensory regression time (minutes) was 181.4, 157.4, 185.3 and 130.6 in group I, II, III and IV respectively. Modified Bromage scale 5 minutes, 15 minutes and 30 minutes after IT in all groups was 0.0. VAS was 1.3, 1.6, 1.6 and 3.1 with significant differences in all groups (P< 0.05). There was non- significant difference in mean age, weight, height and gestational age between all groups (P> 0.05). There was a non- significant difference in APGAR 1, 5, umbilical pH immediately after delivery, neonatal HR after 5minute, 15 minutes and 30 minutes in all groups (P> 0.05). Conclusion: The authors found that dexmedetomidine is a safe and effective adjuvant to intrathecal bupivacaine-dexamethasone in multiparous women undergoing normal vaginal delivery.

To study the mechanical effects of lung edema on the pulmonary circulation, we determined the longitudinal distribution of vascular resistance in the arteries, veins, and microvessels, and the distribution of blood flow in isolated blood-perfused rabbit lungs with varying degrees of edema. Active vasomotor changes were eliminated by adding papaverine to the perfusate. In three groups of lungs with either minimal [group I, mean wet-to-dry weight ratio (W/D) = 5.3 +/- 0.6 (SD), n = 7], moderate (group II, W/D = 8.5 +/- 1.2, n = 10), or severe (group III, W/D = 9.9 +/- 1.6, n = 5) edema, we measured by direct micropuncture the pressure in subpleural arterioles and venules (20–60 micron diam) and in the interstitium surrounding these vessels. We also measured pulmonary arterial and left atrial pressures and lung blood flow, and in four additional experiments we used radio-labeled microspheres to determine the distribution of blood flow during mild and severe pulmonary edema. In lungs with little or no edema (group I) we found that 33% of total vascular pressure drop was in arteries, 60% was in microvessels, and 7% was in veins. Moderate edema (group II) had no effect on total vascular resistance or on the vascular pressure profile, but severe edema (group III) did increase vascular resistance without changing the longitudinal distribution of vascular resistance in the subpleural microcirculation. Perivascular interstitial pressure relative to pleural pressure increased from 1 cmH2O in group I to 2 in group II to 4 in group III lungs.(ABSTRACT TRUNCATED AT 250 WORDS)

IntroductionWhether anxiety and depression are associated with hypertension and to what extent is not clear.AimsThe aim of the present study was to assess any differences in the prevalence of anxiety and depression among different groups of hypertensive patients.MethodsThe study cohort comprised of 127 patients (75 male, mean age 54 ± 14) who underwent assessment of their blood pressure levels and were divided in four groups: group I (normotensives, n = 34), group II (stage 1 HTN, n = 33), group III (stage 2 HTN, n = 30) and group IV (stage 3 HTN, n = 30). The evaluation of anxiety disorder was made by means of Hospital Anxiety Depression Scale (HADS), while the evaluation of depression was made with the Beck Depression Inventory (BDI). Statistical analysis was done with SPSS for windows. P-value was set at 0.05 for differences to be considered significant.ResultsComparing the four groups of patients there was a significant difference both in BDI (8.6 ± 7.0 vs. 11.6 ± 10.4 vs. 27.1 ± 5.8 vs. 32.4 ± 3.9, P < 0.0001) and HADS (10.2 ± 7.2 vs. 9.7 ± 7.0 vs. 16 ± 4.7 vs. 27 ± 5.1, P < 0.0001). We proceeded to comparison among the 4 groups and there was a significant rise in the BDI and HADS in three of the four groups group II > group III > group IV, P < 0.0001.ConclusionThese data suggest that there is a clear burden of anxiety and depression as the levels of BP increase. This finding is of important clinical significance as it could contribute to a different approach of hypertensive patients. A larger cohort study could enlightened the mechanisms involved.Disclosure of interestThe authors have not supplied their declaration of competing interest.

This work assess serum levels of soluble Fas form (sFas) in patients with different stages of laryngeal squamous cell carcinoma(LSCC) to investigate its prognostic significance. We correlate its levels with the morphological changes of peripheral blood cells via buffy coat examinatin. The study population included 70 patients clinically diagnosed and pathohistologically confirmed LSCC in addition to 20 healthy controls. According to TNM classification 33(47.1%) patients were in stage I (group I) and 24(34.3%) in stage II (group II), 13(18.5%) in stage III (group III). The results revealed that the mean serum level of sFas (pg/ml) in the control group was 51.2, in group I was 66.33, in group II was 81.33 and in group III was 112.45. Statistical analysis of the mean of sFas by ELISA test in the patients' groups in comparison to the control revealed a significant increase of both group II and III in comparison to the control group (P < 0.01) but there was no significant difference (P > 0.05) between group I in comparison to either the control or group II. There was a significant difference (P < 0.05) between group I in comparison to group III. LM examination revealed massive extent of the apoptotic cells in group III when compared to both group I and group II. EM examination of the buffy coat revealed apoptotic changes, mainly in the peripheral blood mononuclear cells (PBMNCs), represented by surface membrane ruffles and blebs with clumped nuclear chromatin and vacuolated cytoplasm. In conclusion, this study may help us to better understand one of the escape mechanisms in cancer larynx. This mechanism is represented by the significant increase in both the serum level of sFas and the morphological apoptotic changes that detected in PBMNCs. Soluble Fas may contribute to the progression of laryngeal cancer. It can be used as an attractive target for anticancer therapy and may be considered as a marker of disease progression and poor prognosis in laryngeal cancer.
