Abstract
OBJECTIVES Spondyloarthritis (SpA) results from the interplay between genetic and environmental factors. An emerging modifiable factor is the human intestinal microbiota, which multiple studies in children and adults have shown to be abnormal in SpA patients, including enthesitis related arthritis and ankylosing spondylitis (AS). However, HLA-B27 itself appears to impact the contents of the microbiota and is more common in SpA patients versus controls, thus serving as a confounding factor in most comparative studies. METHODS This was a cross-sectional study that evaluated the contents of the faecal microbiota among 29 patients with HLA-B27+ AS and 43 healthy adults who underwent 16S sequencing and genotyping as part of the TwinsUK Programme. RESULTS HLA-B27 positive+ patients and healthy controls demonstrated substantial clustering based upon diagnosis. Decreased richness was observed among the AS patients, although measures of evenness were similar. After correction for multiple comparisons, several taxa - including Faecalibacterium prausnitzii and Coprococcus - were elevated in AS patients compared to controls, even when restricted to female subjects, while Bacteroides fragilis, Ruminococcus, and Akkermansia muciniphila were depleted in AS patients. CONCLUSIONS Consistent with some previous studies, our study demonstrates in patients with AS associations with Coprococcus, Bacteroides, and Ruminococcus. Other findings, including increased Faecalibacterium, are inconsistent with previous studies and thus potentially underscore the necessity of evaluating HLA-B27 positive controls in studies evaluating the impact of the intestinal microbiota on SpA.

Abstract
Multiple studies have shown the microbiota to be abnormal in patients with spondyloarthritis (SpA). The purpose of this study was to explore the genetic contributions of these microbiota abnormalities. We analyzed the impact of HLA-B27 on the microbiota of children at risk for SpA and compared the microbiota of HLA-B27+ pediatric offspring of ankylosing spondylitis (AS) patients with that of HLA-B27+ children with SpA. Human DNA was obtained from the offspring for determination of HLA-B27 status and polygenic risk score (PRS). Fecal specimens were collected from both groups for sequencing of the V4 region of the 16S ribosomal RNA gene. Among the offspring of AS patients, there was slight clustering by HLA-B27 status. After adjusting for multiple comparisons, five operational taxonomic units (OTUs) representing three unique taxa distinguished the HLA-B27+ from negative children: Blautia and Coprococcus were lower in the HLA-B27+ offspring, while Faecalibacterium prausnitzii was higher. HLA-B27+ offspring without arthritis were compared to children with treatment-naïve HLA-B27+ SpA. After adjustments, clustering by diagnosis was present. A total of 21 OTUs were significantly associated with diagnosis state, including Bacteroides (higher in SpA patients) and F. prausnitzii (higher in controls). Thus, our data confirmed associations with B. fragilis and F. prausnitzii with juvenile SpA, and also suggest that the mechanism by which HLA-B27 is associated with SpA may not involve alterations of the microbiota.

Abstract
OBJECTIVE Cardiovascular (CV) morbidity and mortality are increased in axial spondyloarthritis (axSpA).We conducted a cross-sectional study evaluating the 10-year atherosclerotic cardiovascular disease (ASCVD) risk in axSpA compared to the general US population. METHODS We included 211 adults, 40-75 years old with ankylosing spondylitis (AS) or nonradiographic axSpA from 2 sites, who had available data on comorbidities, medication use, blood pressure measures, and laboratory cholesterol values. General population comparators from the 2009-2014 National Health and Examination Survey (NHANES) cycles were matched 4:1 to subjects, on age, sex, and race. We estimated the prevalence ratio for a 10-year ASCVD risk score ≥ 7.5% comparing axSpA and matched NHANES comparators using conditional Poisson regression. RESULTS Overall, subjects were 53.9 ± 11.2 years old, 69% were male, and 74% were White. The mean 10-year ASCVD risk score was 6.7 ± 6.9% for those with axSpA, and 9.0 ± 10.5% for NHANES comparators. Compared to those with axSpA, the prevalence of current smoking and diabetes was higher among NHANES comparators. The estimated prevalence ratio for a 10-year ASCVD risk score ≥ 7.5% comparing those with axSpA and their age-, sex-, and race-matched comparators was 0.96 (95% CI 0.74-1.24). CONCLUSION The prevalence of a 10-year ASCVD risk score ≥ 7.5% was not significantly different comparing axSpA patients and those drawn from the general population who were similar in terms of age, sex, and race. Future studies should focus on improved CV risk prediction in axSpA, because underestimation by a general population risk score may potentially explain these results.

Abstract
ObjectiveTo evaluate if inpatient infusion treatments for patients with chronic migraine (CM) and history of head trauma and endocrine abnormalities can lead to headache improvement.BackgroundMany patients with CM and history of head trauma have endocrine co-morbidities that can interfere with successful management of headache. In this study, we evaluated if inpatient infusion treatments improved headache outcomes for this patient population.Design/MethodsRetrospective chart review of patients admitted and treated with 4–5 days of intravenous (IV) Dihydroergotamine (DHE), Chlorpromazine, or Valproate for headache. All cases were presented at the Headache Center Case Conference before admission, and plans for addressing co-morbidities were discussed with appropriate specialists and primary care providers. Co-morbidities addressed included diabetes mellitus, pituitary and thyroid dysfunction and endometriosis. During admission, vital signs and appropriate lab work such as serum glucose, thyroid, liver and renal function were monitored. Lifestyle recommendations provided during admission and appropriate follow ups after discharge were arranged with Headache Clinic, primary care, and specialists, when applicable.Results53 patients with CM were included in the analysis. 12 (22.6%) of the 53 patients had both reported history of head trauma and endocrine comorbidity. Of these 12 patients, 8 (66.7%) had improvement in headache up to 6 weeks after admission. Of the 8 that improved, 6 (75%) received DHE and 2 (25%) received Chlorpromazine.ConclusionsInpatient infusion treatments for patients who have CM with history of head trauma and endocrine abnormalities can lead to headache improvement, potentially due to IV infusion therapy along with holistic approaches which include addressing co-morbidities and education on lifestyle modifications. Future studies are needed to evaluate if specific endocrine system dysfunction can predict outcomes from repetitive infusion therapy for persistent headache in patients with CM and a reported history of head trauma.

Abstract
The objectives of the study are to investigate the incidence of new or worsening headache after cochlear implant (CI) surgery and activation and to determine whether there are predictors of associated headache. We performed a cross-sectional survey of patients who had CI surgery. The frequency and severity of headache, onset of headache relative to surgery and device activation, medication use, family history, headache triggers, and accompanying cranial autonomic symptoms were recorded and analyzed. Thirty-seven subjects were enrolled. In the time period after CI surgery but before CI activation, none reported a new headache and four (11%) reported a worsening headache. After CI activation, six (16%) developed new headache and five (14%) developed worsening headache. These 11 subjects also experienced a significantly higher mean of 6.3 headache days/month following CI activation ( p < 0.009). Providers should be aware that new or worsening headache can be reported following CI activation, although not immediately following CI surgery.

Abstract
OBJECTIVE This is a small pilot study to evaluate the effectiveness of an intravenous (IV) valproate sodium therapy protocol for migraine prevention in a population of patients with chronic migraine refractory to multiple preventive medications. BACKGROUND Valproate sodium is an anti-epileptic and mood stabilizer that has been shown to prevent migraine when used daily in oral form. The specific mechanism of action in migraine is unknown, but it may be related to suppressing inflammation and increasing brain Gamma-aminobutyric acid levels. It also may relate to its ability to suppress cortical spreading depression. Multiple studies have suggested that valproic acid and its derivatives may inhibit Calcitonin gene-related peptide. In the present work, we undertook a small pilot study to evaluate the effectiveness of an IV valproate sodium therapy for migraine prevention in a population of patients with chronic migraine refractory to multiple preventive medications. METHODS Fourteen adult patients with chronic migraine were admitted for a 4-day course of IV valproate sodium. Patients received 250 mg of valproate sodium over a standard infusion time of 60 minutes every 8 hours. Most patients received 9 doses over the 4-day course of treatment. One patient had to discontinue after 1 dose of 250-mg valproate sodium, as this patient experienced an increase in his previous symptoms of nausea, vomiting, and vertigo with his first dose. To avoid positive selection bias, we evaluated the first admission for valproate IV therapy in patients with multiple admissions; there was 1 patient with 2 admissions and 1 with 3 admissions for IV valproate sodium. Of note - all admission outcomes for these patients were similar. Headache diaries were reviewed from 1 month before, during, and approximately 2 months after their admission. STATISTICAL ANALYSES Due to the observational nature of the study and small sample size, we did not think that quantitative statistical analysis would add more meaning to this pilot study. Formal quantitative statistical analysis was not performed in this study and descriptive statistical analysis was used due to this being a pilot proof of concept study. Physician clinical judgment in combination with patient reports were used to assign a dichotomous conclusion on clinical improvement for each patient. In the future, we plan to create a larger study, including additional treatment groups for control, such as IV Dihydroergotamine or IV Chlorpromazine, in order to quantify improvement of symptoms. RESULTS A total of 9 out of 13 (69%) patients had an improvement in their headache post-admission and reported a reduction in headache frequency, intensity, and/or use of acute medications 4-6 weeks following their admissions. A total of 5 out of 13 (38%) patients also reported an improvement in headache intensity during the 4-day period of inpatient admission. The other 8 out of 13 (62%) patients reported stable headache pattern. One patient had feelings of restlessness, which improved with prolongation of infusion time to 120 minutes. CONCLUSION These results indicate that this repetitive dosing valproate sodium protocol is a safe and well-tolerated intervention for the treatment of chronic migraine resistant to oral medications. Given the promising outcomes on patient headache improvement with this small pilot study, studies to confirm this benefit in a larger cohort of chronic migraine patients are warranted, preferable with the addition of a blinded control group for comparison.

Abstract
This paper presents a novel method to recover 3D structure of the optic disc in the retina from two uncalibrated fundus images. Retinal images are commonly uncalibrated when acquired clinically, creating rectification challenges as well as significant radiometric and blur differences within the stereo pair. By exploiting structural peculiarities of the retina, we modified the Graph Cuts computational stereo method (one of current state-of-the-art methods) to yield a high quality algorithm for fundus stereo reconstruction. Extensive qualitative and quantitative experimental evaluation (where OCT scans are used as 3D ground truth) on our and publicly available datasets shows the superiority of the proposed method in comparison to other alternatives.

Abstract
OBJECTIVES To study the maternal and perinatal outcome of pregnancies complicated by rheumatic heart disease. METHODS A retrospective study was carried out in the cardio-obstetric clinic of the Postgraduate Institute of Medical Education and Research, Chandigarh (India) over a period of 13 years (1987-1999) involving 486 pregnant patients with rheumatic heart disease. Maternal and perinatal outcome was reviewed. RESULTS Three hundred and four patients (63.3%) had single valve involvement and mitral stenosis was the most predominant lesion (89.2%). One hundred and seventy one (38.6%) patients had undergone surgical correction prior to the onset of pregnancy. One hundred and thirteen patients (22.6%) were identified as NYHA class III-IV. Mitral valvotomy was performed during pregnancy in 48 patients. The incidence of preterm birth and small for gestational age newborns was 12% and 18.2%, respectively. There were 10 maternal deaths, of which eight patients were NYHA III and IV. CONCLUSIONS Rheumatic heart disease in pregnancy is associated with significant maternal and perinatal morbidity in NYHA class III-IV patients.

Abstract
BACKGROUND Ischemic ulcers are usually found above the lateral, and venous stasis ulcers at the medial malleoli. Leg ulcers occur in at least 25% of sickle cell disease (SSD) patients in clinic populations, usually in the malleolar region. The function of the large leg veins in most SSD patients is unimpaired. PATIENTS AND METHODS We determined leg ulcer location in 41 sickle cell anemia (SS), and 4 sickle-beta 0 thalassemic patients with longstanding chronic and/or recurrent leg ulceration, and reviewed published reports of leg ulcers in hereditary spherocytosis and thalassemias. RESULTS Of the 57 legs of the 45 SSD patients with only 1 ulcer, 42 (74%) were medial and 15 lateral. The difference was significant (p < 0.001). Of patients with only a single ulcer, 22 were medial and 4 lateral. Of 15 reported patients with leg ulcers related to spherocytosis or thalassemia, 20/24 (83%) ulcers were medial. CONCLUSIONS The medial malleoli are the most common site of leg ulceration in SSD and in other chronic hemolytic anemias. This suggests that stasis may play a role in the leg ulceration associated with chronic hemolytic anemia.

Abstract
Placental site trophoblastic tumor (PSTT) is very rare. It is an unusual variant of gestational trophoblastic neoplasia usually confined to the uterus, although 10% of patients have metastases. The clinical behaviour of PSTT varies and despite knowledge of its histology, diagnosis of this rare form of trophoblastic disease and prediction of its biological behaviour remains difficult due to only a few cases reported in literature.

Abstract
OBJECTIVE To study the outcome of pregnancy in women with non-cirrhotic portal hypertension (NCPH). METHOD A retrospective analysis of 50 pregnancies in 27 women with NCPH was carried out. Pregnancy outcome was compared in extra hepatic portal vein obstruction (EHPVO) and non-cirrhotic portal fibrosis (NCPF). RESULTS The mean maternal age was 24.60+/-2.857 years, and the disease was diagnosed during pregnancy in 15 (55.6%) patients. Variceal bleeding occurred in 17/50 (34%) pregnancies and the majority (88.2%) of them responded to endoscopic sclerotherapy. Incidence of variceal bleeding during pregnancy was lower in pregnancies where the disease was diagnosed prior to pregnancy (8.6%), and it was 43.5% in EHPVO and 25.9% in NCPF. The mean birth weight of the neonates was 2668.4+/-427.42 g, and the incidence of abortion, prematurity, small for gestational age babies and perinatal death was 20, 17.5, 12.5 and 20%, respectively. Variceal bleeding during pregnancy was associated with a higher incidence of abortion (29.4%) and perinatal death (33.3%). CONCLUSION Variceal bleeding is the most common complication in pregnancies with NCPH. Pregnancies can be allowed and managed successfully in patients with NCPH.

OBJECTIVE To analyse factors associated with maternal mortality in eclampsia and preeclampsia. METHOD Retrospective analysis of 69 maternal deaths due to (eclampsia-61; severe preeclampsia-8) was carried out during a period of 17 years (1982-1998). Maternal condition on admission, associated complications and principal cause of death was analysed in each case. RESULTS Mean time interval between hospitalization and maternal death was 49.56 +/- 62.01 hrs (1-240 hrs). Twenty (28.9%) women died undelivered. Twenty-three (37.7%) women were in grade IV coma and 52.4% of eclampsia patients had recurrent convulsions (> 10) prior to admission. Associated complications in form of hemorrhage, cerebrovascular accidents, acute renal failure, jaundice, aspiration pneumonia and pulmonary oedema were 30.4, 31.8, 34.8, 18.8, 17.8, and 5.8%, respectively. Maternal mortality in eclampsia was significantly low in time period B (4.1%) when magnesium sulphate was used as an anticonvulsant. CONCLUSIONS Maternal condition on admission and associated complications are the major determinant of maternal outcome. Use of magnesium sulphate is associated with significant reduction of maternal mortality.

Abstract
We studied the relationships of selected microbes and the role of consorts in the causation of vaginal discharge which may be due to cervicitis or vaginitis. A total of 93 consecutive patients in the reproductive age group with symptoms of vaginal discharge along with their sexual partners were studied. Samples were collected from the cervix and posterior fornix of the female patients and from the urethra and sub-prepucial area of the male partner for culture of Neisseria gonorrhoeae, Gardnerella vaginalis, Mycoplasma hominis, ureaplasma, candida, aerobic and anaerobic organisms. Apart from cultures, KOH and Gram stain of the discharge were made. Predominant pathogen isolated was Ureaplasma urealyticum from 40 (43.01%) females and 23 (24.7%) males. The next common pathogenic organisms isolated were candida species from 11 (11.8%) females and 5 (5.4%) males and Chlamydia trachomatis in 3 (3.2%) females and 1 (1.1%) male. Various organisms were more frequently isolated from the 29 of 43 (67.4%) couples who had had sexual intercourse 7 days prior to the recruitment as compared to 14 of 43 (32.6%) who had had coitus more than 7 days prior to their recruitment. This may be due to the spontaneous disappearance or decrease in the number of organisms to the level that they could be detected by culture. In our study, 6 (6.5%) of male partners carrying pathogenic organisms were asymptomatic, indicating that their screening and treatment is vital.

Abstract
Pancreatic cancer cells are usually resistant to apoptosis induced by cytotoxic drugs, by activation of surface receptors such as Fas and TNF receptor or by serum or growth factor withdrawal. Actinomycin D (actD) is an inhibitor of RNA synthesis and acts as a potent inducer of apoptosis in several cell lines. In the present study, we investigated the effects of actD on PANC-1 pancreatic cancer cells. ActD caused apoptosis in PANC-1 cells in a dose-dependent manner, as determined by cell growth assays, DNA laddering and TUNEL assays. Induction of apoptosis correlated with activation of the JNK/SAPK pathway and increased expression of Bax but not Bad or p53. PANC-1 cells were completely resistant to Fas antibody and TNF-alpha. In contrast, TRAIL decreased the growth of PANC-1 cells by 22%. Low concentrations of actD (10 ng/ml) enhanced the cytotoxic effects of all 3 cytokines. EGF, FGF-2 and IGF-I did not protect PANC-1 cells from actD-mediated apoptosis. ActD (10 ng/ml) also inhibited the growth of CAPAN-1 and T3M4 pancreatic cancer cells but not MiaPaCa-2 cells. Our observations suggest that actD may act via JNK/SAPK and Bax to promote apoptosis in PANC-1 cells and that it may inhibit the growth of other pancreatic cancer cell lines.

Abstract
Oxidative products of nitric oxide, serum nitrates and nitrites were estimated in 50 primigravidas with preeclampsia and in 50 gestation and age-matched normotensive primigravidas. Thirty three (66%) of these women had mild preeclampsia and 17 (34%) had severe preeclampsia. Serum nitrate and nitrite levels were significantly higher in preeclamptic women (nitrates - 15 +/- 1.17; nitrites - 11.82 +/- 1.16 micromol/L) than in the normotensive pregnant women (nitrates 11.82 +/- 1.16; nitrites - 5.08 +/- 0.47 micromol/L, p < 0.001). In preeclamptic women, serum nitrate and nitrite levels correlated with the severity of the disease (mild preeclampsia nitrate - 14.46 +/- 1.98; nitrite 6.21 +/- 0.84 micromol/L, severe preeclampsia nitrate - 16.65 +/- 3.64; Nitrite - 6.87 +/- 1.56 micromol/L). In preeclampsia there was significant positive correlation between nitrate and nitrite levels and diastolic blood pressure and proteinuria.

Abstract
OBJECTIVE A prospective study was conducted to evaluate the various neurological (clinical, radiological and EEG) complications in patients of eclampsia. METHODS Thirty nine patients of eclampsia were studied regarding neurological findings at presentation and electroencephalographic (EEG) tracings were recorded in each patient. Patients with an abnormal neurologic examination and/or focal or lateralizing findings on EEG, underwent a CT scan (n = 18). Foetal and maternal outcome were recorded. RESULTS The age of the patients ranged from 19-30 (mean +/- SD, 24.2 +/- 3.5) years thirty six patients (92%) had seizures in the antenatal period, 2 (5.4%) patients developed post partum eclampsia and 1 (2.6%) patient had seizures before and after delivery. A diffuse encephalopathy was seen in 9 patients (23.1%), 4 patients (10.2%) had hemiparesis and 1 patient (2.6%) had papilledema. EEG abnormalities were seen in 29 cases (74%) and included generalized slowing (n = 19), generalized sharp waves (n = 9), focal slowing (n = 4), focal sharp waves (n = 2) and spikes (generalized and focal) were seen in 1 patient each. Abnormal CT scan was seen in 10 cases (n = 18). Five patients had generalized infarct was seen in 1 patient each. There were 8 (20.5%) still births and 31 (19.5%) live births and no maternal mortality. CONCLUSIONS Antenatal seizures occur in > 90% cases of eclampsia and less than 10% cases have seizures after delivery. A diffuse encephalopathy is the commonest clinical abnormality along with generalized slowing on EEG. Although cerebral oedema is common focal infarcts may be seen on CT scan.

Abstract
Fifty pregnant women admitted with diagnosis of eclampsia were randomly allocated to magnesium sulphate (Group A) or phenytoin sodium (Group B) treatment group. Incidence of recurrence of seizures maternal as well as perinatal morbidity and mortality were compared in both the groups. Mean maternal age, parity and gestational age was similar in both the groups. Mean birth weight was significantly lower in Group B compared to Group A. Seizure frequency prior to hospitalization was 5.4 +/- 4.7 in Group A and 4.8-3.6 in Group B. Mean time interval between occurrence of first seizure and hospitalization was 9.6 +/- 3.5 hours in Group A and 11.8 +/- 9.3 hours in Group B, the difference was not statistically significant. Women treated with phenytoin had a higher incidence of recurrent seizures (10/25-40%) than those treated with magnesium sulphate (2/25-8%). Majority of the women treated with phenytoin (6/10-60%) had single convulsion after initiation of anticonvulsant therapy and 1 woman of each group had recurrent convulsions (75). There was no significant difference in perinatal outcome in both the groups. Maternal morbidity was comparable in both the groups and there was no maternal death in either of the groups.

Abstract
OBJECTIVES To study calcium metabolism in pre-eclampsia and normotensive gravid women. METHOD Ten milliliters of heparinized blood samples and 24-h urine samples were collected from 50 pre-eclamptic and 50 normotensive primigravidae. Blood samples were studied for calcium uptake, intracellular calcium level and calcium-dependent adenosine triphosphatase activity of red blood cell ghost. Urinary calcium excretion was estimated from the 24-h urine samples. These values were compared in the two groups. RESULTS The mean gestational age at recruitment was similar in both the groups. The mean maternal age was 24.28 +/- 2.41 years in pre-eclamptic and 23.48 +/- 4.16 years in normotensive women. In pre-eclampsia 24-h urinary calcium excretion (71.20 +/- 22.95 mg/day) and calcium-dependent ATPase activity (10.78 +/- 2.40 nmol/Pi/mg protein/min) was significantly lower compared to normotensive primigravidae (calcium excretion = 189.24 +/- 57.06 mg/day; Ca2+-dependent ATPase = 12.64 +/- 2.42 nmolPi/mg /protein per min; P < 0.001). Intracellular calcium levels and calcium uptake at 10 min by red blood cells were significantly higher in pre-eclampsia (P < 0.05). Calcium uptake by red blood cells at 20 and 30 min was similar in both groups. CONCLUSION Pre-eclampsia is associated with increased levels of intracellular calcium, decreased calcium-dependent ATPase activity of erythrocytes and hypocalciuria.

Abstract
BACKGROUND & AIMS Bone morphogenetic proteins (BMPs) belong to the transforming growth factor beta superfamily of signaling molecules. We characterized the expression of BMP-2 and its receptors in human pancreatic tissues and pancreatic cancer cell lines and examined the effects of BMP-2 on mitogenesis. METHODS Expression of BMP-2 and its receptors was determined by Northern blot analysis using specific complementary DNA probes. Distribution of BMP-2 in pancreatic cancers was examined by immunohistochemistry and in situ hybridization. Effects of BMP-2 on mitogenesis were assessed by monitoring cell proliferation and activation of mitogen-activated protein kinase (MAPK). RESULTS Compared with the normal pancreas, pancreatic cancers showed a 12.5-fold (P < 0.01), 2-fold (P < 0.01), and 8-fold (P < 0.01) increase of BMP-2, BMP receptor (R)-IA, and BMPR-II messenger RNA levels, respectively. By immunohistochemistry and in situ hybridization, BMP-2 was expressed in the cancer cells within the tumor mass. There was a significant correlation between the presence of BMP-2 immunostaining in the tumors and shorter postoperative survival. Pancreatic cancer cell lines expressed variable levels of messenger RNA encoding BMP-2 and its receptors. BMP-2 stimulated the growth of two pancreatic cancer cell lines (ASPC-1 and CAPAN-1). This mitogenic effect was associated with MAPK activation and blocked by the MAPK inhibitor PD98059 in CAPAN-1 but not in ASPC-1 cells. In both cell lines, expression of wild-type Smad4 abolished the BMP-2-mediated growth stimulation. BMP-2 inhibited the growth of COLO-357 cells, an effect that was blocked by expressing a dominant negative Smad4. BMP-2 had no effect in three cell lines that underexpressed either the BMP receptors or Smad1. CONCLUSIONS These findings indicate that BMP-2 has the capacity to act as a mitogen when Smad4 is mutated and suggest that it might play a role in the pathobiology of human pancreatic cancer.

Abstract
BACKGROUND To determine the association of chorioamnionitis with placental abruption. SUBJECT AND METHOD Fifty pregnant women admitted with abruptio placentae were compared to an equally large control group in spontaneous labor with no history of antepartum hemorrhage. Swabs from the cervix and placental membranes were cultured for aerobic and anaerobic organisms. Placental membranes were studied histologically in 40 women of study group and 35 of control group for any evidence of chorioamnionitis. RESULTS Specific organisms were isolated in 22 (44%) women in the study group and 19 (38%) women in the control group. The cervical swab microbiological flora was similar in both groups but isolation of specific organisms from placental membrane culture was higher in the study group (40%) compared to the controls (18% p<0.05). Evidence of histologic chorioamnionitis was higher in the study group 12/40 (30%), than in the control group 8/35 (22.85%), but the difference was not significant. CONCLUSION The incidence of silent chorioamnionitis (placental membrane culture positivity) is higher in the abruptio placentae.

Abstract
OBJECTIVES To study the outcome of pregnancy in women with artificial heart valves and to compare the maternal and perinatal outcome in mechanical and bioprosthetic valves. METHOD Retrospective analysis of 34 pregnancies in 29 women who conceived after cardiac valve replacement was carried out. RESULTS The majority of women (76.4%) delivered within 5 years of valve replacement. Anticoagulants were administered in 79.4% of pregnancies. Maternal mortality was 2.9% and maternal morbidity in the form of heart failure, atrial fibrillation, valve thrombosis, thromboembolism, bleeding complications and non-functioning prostheses were 2.9%, 5.8%, 2.9%, 2.9%, 11.7% and 2.9%, respectively. The incidence of prematurity was 5.8% and small for gestational age babies was 11.7%. There was no case of abortion. Two babies (5.8%) were still born, one of which had malformations. Maternal complications were significantly higher in women with bioprostheses, though the complications were more grave in the mechanical prostheses group. The perinatal outcome was almost similar in both the groups. CONCLUSION The perinatal outcome was not different in women with bioprosthetic valves from the ones with mechanical prostheses, but the maternal morbidity was more in women with bioprosthetic valves. Coumarin derivatives were safe and effective and did not lead to embryopathy.

Abstract
BACKGROUND To study placental bed biopsy changes in placenta previa and normally implanted placenta. SUBJECT AND METHOD Fifty placental bed biopsies from 50 patients with placenta previa and 50 placental bed biopsies from normally implanted placenta were taken at cesarean section. Placental bed biopsy was stained with hematoxyline and eosin for histological examination. Both the groups were compared for trophoblastic invasion and vascular changes of placental bed spiral arteries. Statistical analysis was done by Chi-square test. RESULTS Placenta bed biopsy was representative in 42/50 (84%) biopsy samples of the study group (placenta previa) and 35/50 (70%) of the control group (normally located placenta). Trophoblastic giant cell migration into decidua was present in 100% of representative samples of both the groups while migration into myometrium was seen in 66.67% and 51.14% of samples of study and control group. Average number of trophoblastic giant cells per sample was significantly higher in placenta previa (decidua 41.3%, myometrium 52%) than the control group (decidua 17.4%; myometrium 14.5%). Trophoblastic giant cell infiltration into myometrial spiral arterioles was higher in placenta previa (81.83 cells per vessel). Percentage of myometrial spiral arterioles showing physiological changes was significantly higher in the study group (50.39%) compared to the control group (21.14%). Incidence of inflammatory cell infiltration was higher in the study group (42.86%). Hemorrhage into decidua and myometrium were seen in biopsy samples of the placenta previa. CONCLUSION Placenta previa is associated with significantly higher trophoblastic giant cell infiltration and physiological changes of the myometrial spiral arterioles.

Abstract
We reviewed the obstetrical performance and outcome of 15 pregnancies in patients with systemic lupus erythematosus (SLE) (study group) and compared them with 45 age and parity-matched normal pregnancies (control group). Eleven women (73.8%) were in remission phase and 4 (26.7%) had active disease at the time of conception. The time interval between disease diagnosis and the index pregnancy was 4.2 +/- 2.5 years. Two patients with renal involvement had lupus flare-up during the antenatal period. There was no case of lupus flare-up in the postpartum period. Gestational age at delivery was significantly lower in SLE patients (35.9 +/- 2.5 weeks) compared to the control group (37.4 +/- 2.2 weeks). The incidence of intrauterine growth retardation was significantly higher in the SLE patients (40%). There was no case of neonatal lupus or congenital heart block.

Abstract
Two hundred and seventy five pregnancies in patients with congenital heart disease during 1980-1996 were analyzed retrospectively. Maternal and perinatal outcome was compared in 251 pregnancies of women with acyanotic and 24 pregnancies of women with cyanotic heart disease. Congenital heart disease was diagnosed during the index pregnancy in 26.1% of patients and the majority (88.4%) were in NYHA classes 1 and 2. Atrial septal defect (27.7%) was the most common lesion in women with acyanotic heart disease and the majority with cyanotic heart disease had Eisenmenger syndrome, 13 of 21 (61.9%). Sixty pregnancies occurred in patients with surgically corrected lesions (acyanotic, 56; cyanotic, 4). The incidences of abortions (8.3%), stillbirths (13.6%) and small for gestational age (SGA) (36.4%) were higher in cyanotic heart disease compared to acyanotic heart disease (stillbirth, 0.8%; SGA, 6.9%). There was a statistically significant difference in mean maternal age, mean gestational age and mean birth-weight in the surgically corrected and noncorrected lesions in both acyanotic and cyanotic heart disease. There was 1 maternal death in a woman with Eisenmenger syndrome.

Abstract
Retrospective analysis of eclamptic patients was done during two time periods. In time period A (Jan. 1987-Dec. 1988), 79 patients of eclampsia were treated with lytic cocktail and in time period B (April 1992-April 1994), 104 eclamptic patients were treated with magnesium sulfate. The severity of disease, details of labour, delivery, incidence of persistent convulsions and the maternal and perinatal outcomes were compared. Incidence of persistent convulsions was significantly lower with magnesium sulphate (4.8%) compared to lytic cocktail (26.6%). No difference was observed in duration of labour and mode of delivery. Perinatal mortality was significantly lower in magnesium sulphate treated group. Maternal mortality was similar in both the groups (lytic cocktail-3.8%, Magnesium sulphate-2.9%).

Abstract
OBJECTIVES To assess the efficacy of stripping of membranes in initiation of labor and to study its effect on maternal and perinatal morbidity. METHOD One-hundred primigravidae with certain gestational dates were randomized at 38 weeks gestation to either receive stripping of membranes or only gentle cervical examination. Cervical swabs were taken before pelvic examination at 38 weeks and again at the onset of labor. Placental membranes were sent for bacteriological study after delivery in all patients. RESULTS The mean gestational age, parity and Bishop score were similar in both groups at recruitment. Gestational age at delivery was lower in the study group (38.70 +/- 0.63) compared to the control group. Seventy-two percent of the study group and 8% of the control group had spontaneous onset of labor within 7 days of examination. Labor was induced in one patient (2%) of the study group and 16 patients (32%) of the control group. No statistically significant difference was noted in incidence of premature rupture of membranes (PROM), mode of delivery, intrapartum events and perinatal outcome. No increase in neonatal morbidity was seen in association with this procedure. No patient in the study group had clinical evidence of chorioamnionitis. There was no statistically significant difference in the microbiological flora of both groups. CONCLUSION Stripping of the fetal membranes is a safe and efficacious procedure for induction of labor. It decreases the incidence of induction of labor with no increase in incidence of maternal and neonatal morbidity.

Abstract
Centromeres of mammalian chromosomes are rich in repetitive DNAs that are packaged into specialized nucleoprotein structures called heterochromatin. In humans, the major centromeric repetitive DNA, alpha-satellite DNA, has been extensively sequenced and shown to contain binding sites for CENP-B, an 80-kDa centromeric autoantigen. The present report reveals that African green monkey (AGM) cells, which contain extensive alpha-satellite arrays at centromeres, appear to lack the well-characterized CENP-B binding site (the CENP-B box). We show that AGM cells express a functional CENP-B homolog that binds to the CENP-B box and is recognized by several independent anti-CENP-B antibodies. However, three independent assays fail to reveal CENP-B binding sites in AGM DNA. Methods used include a gel mobility shift competition assay using purified AGM alpha-satellite, a novel kinetic electrophoretic mobility shift assay competition protocol using bulk genomic DNA, and bulk sequencing of 76 AGM alpha-satellite monomers. Immunofluorescence studies reveal the presence of significant levels of CENP-B antigen dispersed diffusely throughout the nuclei of interphase cells. These experiments reveal a paradox. CENP-B is highly conserved among mammals, yet its DNA binding site is conserved in human and mouse genomes but not in the AGM genome. One interpretation of these findings is that the role of CENP-B may be in the maintenance and/or organization of centromeric satellite DNA arrays rather than a more direct involvement in centromere structure.

Abstract
OBJECTIVES To study the course of epilepsy in pregnancy and to assess the perinatal outcome. METHODS A retrospective analysis of 219 pregnant patients with epilepsy. The type of epilepsy, drug therapy and seizure frequency were documented. The perinatal outcome of 157 pregnancies with epilepsy was analyzed and compared with that of 471 normal gravidas of similar age and parity. RESULTS Generalized seizures occurred in 203 patients, partial seizures in 13 patients and complex partial seizures in three patients. One hundred fifty-two patients (69.41%) were on monotherapy. Carbamazepine was the most common drug (56.58%) used. Ninety-five patients (43.38%) had seizures in the current pregnancy, five of whom had status epilepticus. There was no maternal mortality in status epilepticus. There was no difference in perinatal outcome between the study and control groups. The incidence of congenital malformations was higher in the control group (5/476, 1.05%) than in the study group (1/160, 0.63%). The incidence of low-birth-weight babies was higher in the study group in patients with gestational seizures. CONCLUSION The course of pregnancy and perinatal outcome was not altered by epilepsy. There was no increase in the incidence of congenital malformations with the use of monotherapy.

Abstract
OBJECTIVES To compare the efficacy and complications of oxytocin dose increments at 20- and 60-min intervals for induction of labor in women with low parity. METHODS One hundred women of low parity requiring induction of labor were randomly allocated to 20- and 60-min oxytocin dose increments, 50 patients in each group. The basal oxytocin dose was 1 milliunit/min and doubling of the oxytocin dose was done at intervals of 20 and 60 min. RESULTS The group with 60-min increments had a decreased incidence of uterine hyperstimulation, cesarean section and operative vaginal delivery. The induction-delivery interval was similar in both groups. CONCLUSION The oxytocin infusion regimen with increments at 60-min intervals is safer than and equally effective as 20-min incremental intervals.

Abstract
Data is presented regarding 57 women who underwent reversal of sterilization procedure. In the majority (90%), the reason for request for reversal of procedure was loss of male child or more than one child. Thirteen subjects never came back for follow-up. Out of 39 subjects in whom follow-up is available for more than 3 months, in 35 (90%) the tubes are patent. There were 25 pregnancies in 21 subjects and incidence of viable pregnancy was 88% with only ectopic pregnancy (4%). In these 35 cases whose tubes were found to be patent post tuboplasty, 18 had laparoscopic ring application, 16 had abdominal tubal ligation and one had undergone vaginal tubal ligation. Thirteen subjects (62%) conceived within 6 months after reversal. In this series, no loupe or operating microscope was used.

Abstract
Menstrual data of 13 control subjects and 88 subjects immunized with three beta-hCG-based vaccine formulations were analysed. Immunization did not change the menstrual regularity; bleeding days were normal (3-7 days) and 89% of the menstrual cycles were within the normal range of 22-35 days. Irregular (short or long) cycles were observed in both immunized and control groups. These were, however, unrelated to prevailing anti-hCG antibody titres or to cross-reactivity of antibodies with hLH.

Abstract
Comparative phase I clinical trials were carried out in 5 centres with three formulations of beta-hCG-based vaccines inducing antibodies against human chorionic gonadotropin. The objectives of these trials were to determine their relative immunogenicity, duration, reversibility and safety. A total of 116 tubal ligated women volunteers were enrolled in the study and 101 subjects were followed-up for one year or more until the antibody titres declined to near zero levels. Every woman receiving the vaccine produced anti-hCG and anti-tetanus antibodies. Clinical examination carried out at intervals of 4-6 weeks revealed no abnormality. No serious side effects or adverse reactions were reported with any of the formulations during primary immunization with three monthly injections of the vaccine. Eleven women, however, demonstrated hypersensitivity to test dose at the time of the booster injection. The reaction was to tetanus toxoid; gonadotropin subunits conjugated to another carrier did not evoke any such reaction. Progesterone in bleeds taken at midluteal phase, as well as complete progesterone and estradiol done in two immunized women, indicated normal ovulatory cycles. Immunization with these formulations had no significant effect on haematological, clinical chemistry and other metabolic parameters. In summary, the results indicate that none of the three beta-hCG-based contraceptive vaccines had any adverse effects clinically, on endocrine status and metabolic parameters. Formulations A and B induced comparatively higher anti-hCG titres than M. Thus, further work can be undertaken to study the efficacy of these vaccines in humans for preventing pregnancy.

Abstract
A total of 307 amniotic fluid analysis done in 344 Rh negative immunised mothers showed that 46, 83 and 178 delta OD values at 450 millimicrons fell in the upper, middle and lower zones of Liley's charts respectively. The correlation of spectrophotometric analysis with the condition of the baby at birth was about 95 per cent in the upper and lower zones. In the middle zone, however, it was about 75 per cent only. Also, in 7 women in whom the OD at 450 millimicrons fell in the middle zone, the babies were found to be Rh negative; in another baby, the OD difference fell in upper zone. In spite of these limitations amniotic fluid examination seems to be an important single guide to severity, being superior to other parameters like previous obstetric history, antibody titre alone and Liley's charts, which are still widely used.

Abstract
Data is presented regarding 20 translocated intrauterine contraceptive devices (IUCD). Successful laparoscopic removal was made in 13 (65%) cases though all these devices were Copper 'T' 200 model which tend to produce dense adhesions. Only when the IUCD was suspected to be partially or fully in the gut lumen or thick adhesions were present, or the device was not visualised, was laparotomy performed. Hence it is advocated that laparoscopy should be performed as a routine in patients with suspected translocated IUCD, as it obviates the need for laparotomy and thus decreases the duration of the hospital stay as well as preventing morbidity associated with laparotomy.
