Day 1 Wavefront Aberrometry for Prediction of Refractive Outcomes at Year 1 in Myopic LASIK
Authors: Yu Charles Q. , Manche Edward E. 
Published: March 2015

PURPOSE:
To determine amount of change in wavefront aberrometric measurements from 1 day to 1 year after myopic LASIK.

METHODS:
One hundred five eyes of 105 patients underwent wavefront-guided LASIK. Objective wavefront aberrometric refractions were recorded preoperatively, at postoperative day 1, and at postoperative year 1. Subjective manifest refractions were also collected at postoperative year 1.

RESULTS:

When comparing objective wavefront aberrometric refractions at postoperative year 1 to postoperative day 1, there was a mean 0.33 diopter spherical equivalent myopic shift. There was no significant difference in the number of eyes within 1.00 diopter of emmetropia spherical equivalent measured by wavefront aberrometric refraction at postoperative day 1 or year 1. There was a correlation of R
2
= 0.14 between degree of preoperative myopia and myopic shift. Higher-order aberrations were overall not increased at day 1 but increased significantly by year 1. Objective aberrometric refractions at postoperative day 1 can be useful in prediction of long-term refractive outcomes.

CONCLUSIONS:
There is a small myopic shift and an increase in higher-order aberrations when comparing wavefront aberrometry results at postoperative day 1 with those at postoperative 1 year.

Corneal Topographic Astigmatism (CorT) to Quantify Total Corneal Astigmatism
Authors: Alpins Noel , Ong James K. Y. , Stamatelatos George 
Published: March 2015

PURPOSE:
To evaluate the performance of corneal topographic astigmatism (CorT) based on total corneal power measurements.

METHODS:
Anterior, posterior, and total corneal power measurements of 526 virgin eyes obtained using the CSO Sirius tomographer (Costuzione Strumenti Oftalmici, Scandicci, Florence, Italy) were analyzed. Individual CorTs were created from each set of data. These CorTs were assessed using ocular residual astigmatism (ORA), which quantifies corneo-refractive differences. A low standard deviation of the ocular residual astigmatism (ORAsd) indicates a low variability between corneal astigmatism and refractive cylinder. A low mean of the ORA magnitude indicates a close correlation of refractive cylinder and corneal astigmatism.

RESULTS:

The CorT based on total corneal power measurements had an ORAsd of 0.30 diopters (D) and a mean ORA magnitude of 0.53 D. The CorT candidates based on anterior corneal power measurements all had an ORAsd of at least 0.32 D, and the mean ORA magnitudes were all 0.64 D or greater. Both the ORAsd and mean ORA magnitude of the CorT based on total corneal power measurements were significantly less than those of the CorT based on anterior corneal power measurements (both
P
< .001, as estimated via bootstrapping).

CONCLUSIONS:
The CorT based on total corneal power measurements corresponds better, both in variability and closeness, with manifest refractive cylinder than the CorT based on anterior corneal power measurements. This total CorT would be fundamental when planning toric intraocular lenses or limbal relaxing incisions or other corneal astigmatic surgery.

Comparison of Corneal Shape Changes and Aberrations Induced By FS-LASIK and SMILE for Myopia
Authors: Gyldenkerne Anders , Ivarsen Anders , Hjortdal Jesper Ø. 
Published: March 2015

PURPOSE:
To compare corneal curvatures, corneal power calculations, and higher-order aberrations (HOAs) of femtosecond laser-assisted LASIK (FS-LASIK) with small incision lenticule extraction (SMILE) following surgery for moderate to high myopia.

METHODS:
A retrospective study of 736 eyes of 368 patients treated with SMILE and 148 eyes of 74 patients treated with FS-LASIK. Preoperative mean spherical equivalent was −7.3 ± 1.5 diopters in the SMILE group and −7.6 ± 1.3 diopters in the FS-LASIK group. Corneal curvatures, corneal power calculations performed by ray tracing, and HOAs measured with Scheimpflug technology before and 3 months after surgery were analyzed.

RESULTS:

Corneal curvatures changed significantly in the anterior corneal surface, but not in the posterior corneal surface, in both groups; after SMILE, the sagittal curvature was constant for the central 4-mm diameter, in contrast to FS-LASIK where the curvature showed a gradual steepening with increasing diameter. Corneal power calculations were different across the cornea depending on the measurement diameter between the two groups postoperatively. Measured over a 5-mm zone on the total cornea, FS-LASIK induced 0.11
µ
m more coma (
P
< .001) and 0.13
µ
m higher spherical aberration (
P
< .001) as compared to SMILE; similar results in other HOAs were seen for the anterior corneal surface. Negligible differences in HOAs were induced on the posterior corneal surface.

CONCLUSIONS:
SMILE and FS-LASIK produced distinct changes in anterior corneal shape evident in different postoperative corneal curvatures and power measurements between the two groups. Postoperative HOAs were much lower after SMILE as compared to FS-LASIK.

A Randomized Controlled Study to assess the Role of Routine Third Trimester Ultrasound in Low-risk Pregnancy on Antenatal Interventions and Perinatal Outcome
Authors: Dhumale Hema , Pujar Yeshita , Revankar Komal Gurunath 
Published: March 2015

ABSTRACT

Objective
To assess the role of routine third trimester ultrasound in low-risk pregnancy on antenatal interventions and perinatal outcome.

Design
Randomized controlled study.

Setting
KLES Dr Prabhakar Kore Hospital and Medical Research Center, Belgaum.

Subjects
A total of 290 low-risk pregnant women between 34 and 37 weeks attending antenatal clinic and fulfilling inclusion criteria were allotted using computer-generated randomization numbers into study and control groups.

Intervention
In study group, third trimester ultrasound was performed to assess fetal growth, amniotic fluid index (AFI), malpresentations, and late onset fetal anomalies. In control group, no routine ultrasound was performed, unless indicated by clinical suspicion during subsequent visits. High-risk fetuses identified were managed as per the standard protocol. All women were followed to assess antenatal interventions, intrapartum events and perinatal outcome.

Results
Detection of high-risk fetuses antenatally in study and control groups was 17.25 and 2.07% respectively. This difference was statistically significant (p = —0.0001). Rates of antenatal interventions among study and control were 24.8 and 4.44% respectively. Prevalence of small for gestational age (SGA) fetuses among study and control was 6.9 vs 11.03% respectively. This difference was not statistically significant (p = —0.253). There was no statistical difference in adverse intrapartum events, cesarean section rate for nonreassuring cardiotocography (CTG), low Apgar score and neonatal intensive care unit (NICU) admissions among study and controls.

Conclusion
Routine third trimester ultrasound is a logical solution for detection of high-risk fetuses in low-risk pregnancies which would otherwise be missed by clinical examination. However, this leads to an increase in antenatal interventions without significantly influencing the perinatal outcome.

Intrapartum Amniotic Fluid Volume Estimation in Low-risk Pregnancy as a Predictor of Perinatal Outcome
Authors: Jeanet J , Benjamin Santosh Joseph , Mathews Jiji Elizabeth , Rathore Swati , Sebastian Ajit , Thomas Elsy 
Published: March 2015

ABSTRACT

Objectives
The study was undertaken to determine the efficacy of routine estimation of amniotic fluid volume using the amniotic fluid index (AFI) as a means of predicting an adverse perinatal outcome in low-risk pregnancies.

Materials and methods
Five hundred and three singleton lowrisk pregnancies with cephalic presentation between 37 and 40 weeks and 6 days of gestation with intact or ruptured membranes had AFI estimations within 36 hours of delivery.

Results
The frequency of nonreassuring fetal heart patterns and perinatal outcomes among patients with oligohydramnios (<5 cm), borderline oligohydramnios (5 to 8 cm) and normal (>8 cm) liquor were compared and not found to be different. Cesarean section for nonreassuring fetal status was also similar in the three groups.

Conclusion
This study suggests that AFI estimation during labor in low-risk pregnancies does not predict adverse perinatal outcomes. Further studies are needed to verify this impression.

Surprise in Pandora Box: Spontaneous Intra-abdominal Hematoma in Pregnancy
Authors: Sreedhar Shruthi , Rajeswari KS , Sivasundari M 
Published: March 2015

ABSTRACT
Spontaneous intraperitoneal hemorrhage is a rare medical condition associated with high mortalities. It was first described in pregnancy by Barber in 1909. Approximately in an average of 30% of reported cases, the source of bleeding was not identified. Most patients with spontaneous hemoperitoneum frequently presented with acute abdominal pain and might present a wide variety of other clinical presentations.

Published: March 2015

ABSTRACT
Aggressive angiomyxoma is a rare, slow-growing myxoid neoplasm that occurs almost exclusively in the genital, perineal and pelvic regions of adult women. Aggressive angiomyxoma mostly occurs during the reproductive years.1 It carries a high risk for local relapse. Long term follow up of cases is very essential. We describe a case of a 42-year-old woman presenting with a large swelling on the posterolateral aspect of labia major diagnosed to have aggressive angiomyxoma.

Placenta Percreta: An Unusual Etiology for Spontaneous Rupture of Uterus Near Term
Authors: Varshney Anupam , LNU Neerja , Varma Manju , Thakral RK 
Published: March 2015

ABSTRACT
Uterine rupture is a life-threatening complication in pregnancy with an incidence of 0.07%, out of which 80% are spontaneous rupture. Placenta percreta is the rarest form of placental implantation abnormalities, with an incidence 1 in 2500 pregnant women.1,2 Spontaneous uterine rupture due to placenta percreta is very rare, with an incidence of 1 in 4,366 pregnant women.3 It often occurs in patients with a history of scar in the uterus.4 Placenta percreta-induced spontaneous uterine rupture at term with previous lower segment cesarean section (LSCS) is difficult to diagnose. A 25-year-old pregnant woman, with history of one incomplete abortion treated by dilatation and curettage followed by a vaginal delivery with stillbirth and one LSCS again with stillbirth at term, was admitted in the emergency ward with history of approx 9 months amenorrhea, breathlessness, pain in abdomen (unable to lie down or even sit), vomiting and loss of fetal movements for last 24 hours. O/E: GC fair, afebrile, Pallor +++, pedal edema +, pulse 100/minutes regular, resp. rate; 40/minutes, thoracic, BP 110/70 mm Hg, lung fields clear with no abnormality detected in heart. On P/A: skin was stretched and a Pfannensteil scar healed by primary intention was present Abdomen tense, tender therefore fundal height could not be assessed. Fetal parts were not palpable and lie/presentation could not be made out. FHS were absent. On P/V; os closed with uneffaced cervix, presenting part could not be made out and was high. No bleeding or leaking per-vaginum was present. Hb 6.7 gm%, TLC 15600, DLC P90, L8, E2, M0. Ultrasound done on 27.5.12 (one month back) outside revealed 32.3 weeks gestation with normal scar thickness, placenta located in upper segment, grade I. No comment was made on the interface between placenta and myometrium in ultrasound report.
Patient was subjected to emergency laparotomy, massive hemoperitoneum was found. Examination of uterus revealed an intact previous scar. A full term male stillborn baby was delivered by uterine scar (LSCS) on 21.6.2012, at 10.30 pm The placenta could not be delivered as there was no plain of cleavage between placenta and myometrium. Uterus was exteriorized and to surprise there was a rent of about 3 × 2 cm at left cornua, placental tissue peeping out on removing the clots. Subtotal hysterectomy was performed. Three units blood were transfused. Postoperative period was uneventful and the patient was discharged in satisfactory condition on 9th day. Histopathological examination of the uterine specimen revealed placenta percreta. To conclude uterine rupture should be considered in the differential diagnosis in pregnant women who present with acute abdomen with or without shock.

Primary Extranodal Hodgkin's Lymphoma presenting with a Single Pelvic Mass
Authors: Kiran Gurkan , Canaz Emel , Sayar Hamide , Serin Salih , Balakan Ozan 
Published: March 2015

ABSTRACTIntroductionAlthough lymphomas can arise from a wide variety of tissues, primary extranodal presentation is predominantly a feature of non-Hodgkin's lymphomas. Primary pelvic extranodal Hodgkin's lymphoma is a rare malignancy. We presented a case of primer retroperitoneal Hodgkin's lymphoma initially presumed gynecologic malignancy. We discussed its rarity, staging and management.Case ReportA 75-year-old woman was referred to our hospital with persisting pelvic mass. Pelvic examination revealed an ill-defined immobile mass with hard in consistency. The mass 100 × 75 mm in diameter, invading right parametrium, perivesical space and bladder wall was detected in CT and there were no signs of metastases or enlarged lymph nodes. Diagnostic laparoscopy was suggested but the patient refused the surgery due to her advanced age. One year later, she presented with the symptoms of fever, sweats and fatigue. Hodgkin's lymphoma was diagnosed via laparoscopic biopsy of the mass located at retroperitoneal space anteriorly to the uterus. CT examination revealed multiple swollen lymph nodes and a pulmonary nodule; thus, stage 4 disease was established. International prognostic score was 2, indicating 67% progression free survival; however, patient died due to respiratory failure after the first course of ABVD chemotherapy.ConclusionAlthough gynecologists rarely experience primary extranodal lymphomas particularly Hodgkin's disease, lymphoid malignancies should be kept in mind in differential diagnosis of pelvic masses. This disease can rarely arise adjacent to gynecologic organs in retroperitoneal space, and this presentation can be misinterpreted as a gynecological malignancy.How to cite this articleKiran G, Canaz E, Sayar H, Serin S, Balakan O.

ABSTRACTAcute pancreatitis in pregnancy is rare, with the incidence being 3 in 10,000 pregnancies. Its occurrence is of great concern to clinicians as they are dealing with two lives and increased incidence of morbidity.Here, we report two unique cases of acute pancreatitis in the 3rd trimester. Both presented with symptoms of vomiting and pain abdomen. One patient was a primi at 35 weeks with gestational hypertension on tablet labetalol 50 mg tds, tablet metformin for polycystic ovarian syndrome (PCOS) and thyroxine replacement for hypothyroidism. Her baseline amylase and lipase values were 157 and 475 respectively. She had emergency lower segment cesarean section (LSCS) for severe oligohydramnios. Intraoperative period was uneventful. The second patient was a primi at 34 weeks and 4 days and preterm premature rupture of membranes (PPROM). Her baseline amylase and lipase values were 1449 and 550. Patient was induced with prostaglandin E2 (PGE2) gel and delivered normally. Both patients were managed conservatively with a multidisciplinary team approach.How to cite this articleThirugnanasambandam RP, Palaniappan N, Narayanan CD, Radha V.

Authors: Ghoshal Soma , Mittal Anushree , Manjula BC 
Published: March 2015

ABSTRACT
Retained placenta is a serious cause of postpartum hemorrhage and maternal mortality. The optimal management of placenta accreta remains a topic of debate.
We report here a 37-year-old woman with previous two cesareans and two curettages, with postdelivery retained placenta accreta who was diagnosed properly and underwent successful conservative treatment with hysteroscopic resection, with conservation of uterus.
Placental tissue invasion at the scar site was diagnosed by ultrasound and MRI in a relatively asymptomatic patient. β-hCG value was on lower side and with a differential diagnosis of placental site trophoblastic tumor (PSTT). Hysteroscopic tissue biopsy was done and a ball of tissue approximately 655 cm invading the previous cesarean scar was visualized. Biopsy report came out to be retained placental tissue. Hysteroscopic resection was done with laparoscopic guidance. Patient followup done with repeat ultrasound and β-hCG.

ABSTRACTAmniotic fluid embolism (AFE) is a rare and often fatal obstetric condition, characterized by sudden cardiovascular collapse, altered mental status, and disseminated intravascular coagulation (DIC). The disease is rare, with an incidence ranging from one in 600 to one in 80,000, perhaps because there is no established laboratory marker diagnostic suitable for both survivors and fatalities alike. We present a case of AFE in a low-risk primigravida which was successfully managed by a multidisciplinary team.How to cite this articleMehta P, Devadason L, Vijayaraghavan J.

ABSTRACT
Krukenberg tumors classically refer to secondary ovarian malignancy. The primary is mostly from female genital tract, breast and gastrointestinal tract. Krukenberg tumors account for 30 to 40% of metastatic cancers to the ovaries. The average age of occurrence is 45 years. Most of the Krukenberg tumors are histopathological diagnosis done postoperatively. We do report a case of Krukenberg tumor in an adolescent girl.

Is there an Association between Central Vein Stenosis and Line Infection in Patients with Tunnelled Central Venous Catheters (TCVCs)?
Authors: Aitken Emma , Honour Patrick , Johnson Natalie , Kingsmore David 
Published: March 2015

Purpose Central vein stenosis (CVS) and line infection are well-recognized complications of tunnelled central venous catheters (TCVCs) in patients on haemodialysis. The aim of this study was to evaluate any relationship between CVS and line infection. Methods Analysis of 500 consecutive patients undergoing TCVC insertion was undertaken. Data were collected on patient demographics, details of line insertion and duration, culture-proven bacteraemia and presence of symptomatic CVS. Logistic regression analysis was used to determine risk factors for CVS and bacteraemia. Results Mean patient age was 59.0 years (range: 17-93). Mean number of catheter days was 961.1 ± 57.6 per TCVC; 39.4% of TCVCs were associated with culture-proven bacteraemia and 23.6% developed symptomatic CVS. Bacteraemia and CVS were inevitable complications of all TCVCs. The time to symptomatic CVS was longer in patients with bacteraemia than without (1230.91 ± 101.29 vs. 677.49 ± 61.59 days, p<0.001). Patients who had early infection within 90 days of TCVC insertion were less likely to develop CVS (5.9% vs. 22.8%, p<0.001). There was no difference in the bacteraemia rate per 1,000 catheter days between patients with and without CVS (2.62 ± 1.41 vs. 2.35 ± 0.51; p = 0.98). Number of line days (odds ratio (OR) 1.02, p = 0.003), age (OR 1.04, p = 0.04) and culture-proven line infection (OR 0.59, p = 0.014) were all independently associated with CVS. Conclusions Our results suggest that early line infection may be protective against CVS. Alternatively, there may be two distinct predisposition states for CVS and line infection. Further studies are needed to confirm our association and investigate causation.
Transposition, Elevation, Lipectomy and V-Wing for Easy Needling
Authors: Bourquelot Pierre , Karam Lamisse , Robert-Ebadi Helia , Pirozzi Nicola 
Published: March 2015

Purpose The purpose of this study is to report surgical techniques to facilitate cannulation of deep matured veins. Methods and Results 1) Basilic vein tunnel superficialization with rerouting in an anterior tunnel is mandatory for brachial-basilic arteriovenous fistula (AVF), mostly performed in a second surgical stage. The elevation technique, which could necessitate cannulation of the vein through the overlying scar, is not advisable. 2) Femoral vein superficialization is a one-stage surgical operation. Complications of this high-flow AVF are distal ischemia (diabetes and occlusive arterial disease are contraindications), iliac vein stenosis due to intimal hypertrophy and cardiac issues. Nevertheless, we have achieved high long-term patency rates (N = 70). Primary patency rates at 1 and 9 years were 91% ± 4% and 45% ± 11%, respectively. Secondary patency rates at 1 and 9 years were 84% ± 5% and 56% ± 9%, respectively. 3) Lipectomy for superficialization of the forearm radial-cephalic AVF is described for obese patients. Subcutaneous tissues are resected using two transverse incisions. Mobilization of the vein is avoided. At 3 years (N = 49), we recorded 63% ± 8% and 88% ± 7% primary and secondary patency rates, respectively. Anterior transposition of the forearm basilic vein is not necessary when using microsurgery for creation of distal ulno-basilic AVF. 4) VWING is a novel surgically implanted device to help buttonhole technique cannulation. It is too early to draw any conclusion from the preliminary published reports. Conclusions Tunnel-transposition and lipectomy are efficient techniques to allow easy needling of deeply situated upper-arm basilic vein, and cephalic vein in obese patients, respectively.
