Antimalarial and cytotoxic quassinoids from the roots of Brucea javanica

Two new quassinoids, brujavanol A (1) and brujavanol B (2), along with five known quassinoids (3–7), were isolated from the roots of Brucea javanica. Their structures were elucidated by spectroscopic methods. The antimalarial and cytotoxic activities of the isolated compounds were also assessed. Compounds 1 and 2 exhibited significant in vitro cytotoxicity against human oral cavity cancer (KB) cells with IC₅₀ values of 1.30 and 2.36 μg/ml, respectively, whereas compound 3 showed excellent antiplasmodial activity against the Plasmodium falciparum strains, K1 (IC₅₀ = 0.58 μg/ml).     

Fetal hydrometrocolpos with pre‐axial mirror polydactyly as a new variant of McKusick‐Kaufman syndrome

This report describes a variant of McKusick‐Kaufman syndrome presenting with a large fetal abdominal cyst of hydrometrocolpos at 37 weeks of gestation. The diagnosis was based on the ultrasound findings of a large homogeneous hypoechoic cyst (diameter of >10 cm) with incomplete septum, thickened wall, superiorly connecting to the dilated uterus, consistent with hydrometrocolpos. Additionally, pre‐axial mirror polydactyly of the left foot was suspected. Postnatal examination/work‐up confirmed the prenatal findings. This is the first report of prenatal diagnosis of hydrometrocolpos with complex polydactyly of mirror image pre‐axial duplications containing nine toes instead of six‐toe postaxial polydactyly.     

Effectiveness of a back care pillow as an adjuvant physical therapy for chronic non-specific low back pain treatment: a randomized controlled trial

[Purpose] The aim of this study was to investigate the effect of a back care pillow (BCP) on pain, lumbar range of motion (LROM) and functional disability of patients with chronic non-specific low back pain (LBP). [Subjects and Methods] Fifty-two subjects who were aged between 20–69 years old, who presented with LBP of more than 3 months duration with a numerical rating scale (NRS) value of at least 4 were randomly assigned to treatment (BCP) and control (CON) groups. Participants in each group received six sessions of the 30 minutes treatment for two weeks. The BCP group was asked to wear the BCP during the daytime during the study period. Pain, lumbar ROM and functional disability were assessed before and after the 2-week treatment, and at the end of a 12-week follow up. [Results] After the 2-week treatment and 12-week follow up, all outcomes had improved in both groups; the BCP group had maintained the decrease in pain intensity and improved lumbar ROM in the extension position after the 12-week follow up, and showed better improvements in all outcomes at 2 weeks and after the 12-week follow up. [Conclusion] BCP combined with physical therapy had better pain, lumbar ROM and functional disability outcomes than physical therapy alone.Key words: Lower back support, Chronic low back pain, Numerical rating scale     

Giant choledochal cyst and infantile polycystic kidneys as prenatal sonographic features of Caroli syndrome

Caroli syndrome is a developmental disorder caused by complete or partial arrest of ductal plate remodeling, leading to dilated bile ducts along with fibrosis surrounding the portal tracts. It is most commonly associated with autosomal recessive polycystic kidney (ARPKD). We report a unique case of Caroli syndrome, diagnosed prenatally at 24 weeks of gestation in a 29-year-old Thai woman. Ultrasound findings revealed the association of a fetal giant choledochal cyst with ARPKD. Autopsy findings showed ductal plate malformation, typical of Caroli syndrome, associated with giant choledocal cyst and ARPKD.     

Efficacy and Safety of Ferrous Bisglycinate and Folinic Acid in the Control of Iron Deficiency in Pregnant Women: A Randomized,Controlled Trial

Iron deficiency in pregnancy is a major public health problem that causes maternal complications. The objective of this randomized, controlled trial was to examine the bioavailability, efficacy, and safety of oral ferrous bisglycinate plus folinic acid supplementation in pregnant women with iron deficiency. Subjects (12–16 weeks of gestation, n = 120) were randomly allocated to receive oral iron as ferrous bisglycinate (equiv. iron 24 mg) in supplement form with folinic acid and multivitamins (test group, n = 60) or as ferrous fumarate (equiv. iron 66 mg iron, control group, n = 60) after breakfast daily. Iron absorption was assessed by measuring fasted serum iron levels at 1 and 2 h immediately after supplementation. Hematological biomarkers and iron status were assessed before intervention, and at 3 and 6 months. Side effects were monitored throughout the intervention. A significant increase in serum iron was seen in both groups (p < 0.001) during the bioavailability assessment; however, the test group increases were comparatively higher than the control values at each timepoint (p < 0.001). Similarly, both test and control groups demonstrated a statistically significant increases in hemoglobin (Hb) (p < 0.001), erythrocytes (p < 0.001), reticulocytes (p < 0.001), mean corpuscular volume (MCV) (p < 0.001), mean corpuscular hemoglobin (MCH) (p < 0.001), mean corpuscular hemoglobin concentration (MCHC) (p < 0.001), % transferrin saturation (p < 0.001), and ferritin (p < 0.001) at 3 and 6 months after supplementation. However, in all cases, the test group increases were numerically larger than the control group increases at each timepoint. The test intervention was also associated with significantly fewer reports of nausea, abdominal pain, bloating, constipation, or metallic taste (p < 0.001). In conclusion, ferrous bisglycinate with folinic acid as a multivitamin nutraceutical format is comparable to standard ferrous fumarate for the clinical management of iron deficiency during pregnancy, with comparatively better absorption, tolerability, and efficacy and with a lower elemental iron dosage.     

Prenatal sonographic diagnosis of Majewski syndrome

Majewski syndrome is an autosomal recessive disorder characterized by short ribs, polydactyly, short limbs, and a cleft lip. A 26-year-old woman with no family history of genetic diseases presented at 31 weeks' menstrual age with preterm labor and underwent prenatal sonography to screen for fetal anomalies. Sonography revealed a small thorax, markedly short ribs, micromelia, polydactyly, a cleft lip, dolichocephaly, and severe oligohydramnios. The other structures appeared normal. The most likely diagnosis was Majewski syndrome. Vaginal breech delivery was allowed to proceed. The 1,850-g male newborn died of respiratory failure shortly after birth. The postnatal appearance and radiographs confirmed the prenatal diagnosis.     

Prenatal sonographic diagnosis of diastrophic dwarfism

A healthy 27-year-old pregnant woman underwent sonographic examination because her uterine size was large for 20 weeks' menstrual age. Sonograms showed short fetal limbs with hitchhiker thumbs and toes, thoracic scoliosis, clubbed feet, and polyhydramnios. The ossification of all bony structures appeared normal, and there was no evidence of fractures. On the basis of these sonographic findings, we diagnosed skeletal dysplasia and short-limbed dwarfism, most likely diastrophic dwarfism. We counseled the parents, and the pregnancy was continued. At 37 weeks menstrual age, the patient vaginally delivered a male infant that weighed 2,560 g. The infant survived with respiratory support during his first few days of life. Postnatal physical and radiologic examinations confirmed the prenatal diagnosis of diastrophic dwarfism. Sonography is the modality of choice for prenatal detection of diastrophic dwarfism.     

Prenatal sonographic features of isolated hypoplastic left heart syndrome

Hypoplastic left heart syndrome (HLHS) is a spectrum of fetal conditions associated with severe hypoplasia of the left ventricle and left ventricular outflow tract. The purpose of this series was to focus on the sonographic prenatal features of isolated HLHS. Based on the 5 cases presented here, the prenatal sonographic features of HLHS include small-sized left ventricle, atretic or hypoplastic mitral valves with restricted motion and a small amount of antegrade flow or regurgitation, and hypoplastic ascending aorta. Retrograde flow in the transverse aortic arch strongly suggests inadequate systemic output from the left heart. Tricuspid regurgitation is common and increases the chance for the development of hydrops. Other findings may be helpful, including left ventricular hyperechoic endocardium and increased nuchal translucency at 11-14 weeks. With careful fetal echocardiography, HLHS may be readily observed on a 4-chamber view as either a small or even absent left ventricle.     

Sonographic markers of hemoglobin Bart disease at midpregnancy.

OBJECTIVE: To evaluate the efficacy of various sonographic markers at midpregnancy in predicting fetal hemoglobin Bart disease. METHODS: Four hundred eighty-eight pregnancies at risk of having fetuses with hemoglobin Bart disease were recruited for prenatal diagnosis with cordocentesis at 18 to 21 gestational weeks. Before cordocentesis, the sonographic markers, including cardiothoracic ratio, placental thickness, pericardial effusion, pleural effusion, ascites, subcutaneous edema, cord edema, dilated umbilical vein, and amniotic fluid index, were assessed and recorded. The definite fetal diagnosis was based on blood analysis. The efficacy of each sonographic marker in predicting hemoglobin Bart disease was evaluated by sensitivity and specificity. RESULTS: Among 488 pregnancies undergoing prenatal diagnosis, 100 fetuses were proved to be affected by hemoglobin Bart disease. The cardiothoracic ratio gave the highest sensitivity, 95.0%, with specificity of 96.1%, followed by placental thickness. Signs of hydrops fetalis were observed in 33.0% of cases; they did not increase the sensitivity of the cardiothoracic ratio but strongly reinforced the diagnosis when they appeared. CONCLUSIONS: At midpregnancy, sonographic markers can effectively differentiate normal pregnancies from those with fetal hemoglobin Bart disease. Among couples at risk with no sonographic markers, the risk of having an affected child is nearly eliminated. The most sensitive marker was the cardiothoracic ratio, followed by placental thickness.
