Authors: Shrestha Junu , Shrestha Rami 
Published: September 2017

Background: Rupture uterus is a serious obstetric complication which if diagnosed and managed early improves foetomaternal outcome.Objectives: To determine the frequency, causes, management aspects and foeto-maternal outcome of uterine rupture.Methods: This is a cross sectional observational study conducted in Department of Obstetrics and Gynaecology of Manipal Teaching Hospital from July 2012 to June 2015. All cases of rupture uterus, both complete as well as incomplete, diagnosed during surgery were included. Patient’s demographic variables, clinical presentation, risk factors for rupture were studied. Factors related to rupture like the type, nature and site of uterine rupture were noted. The operative management, maternal and neonatal outcome of the patients was reviewed. All the information was entered in the Microsoft Excel chart sheet. Data was analyzed using simple frequencies and percentages.Results: There were 22 cases of uterine rupture and 7987 deliveries during that period giving frequency of 2.8 rupture uterus in every 1000 deliveries. Uterine scar following previous cesarean section was the commonest (72.7%) cause for rupture uterus. Repair was the commonest (86.4%) surgical treatment done. There was no maternal mortality. Blood transfusion was needed two-third of the cases. Other complications were bladder injury (9.1%), paralytic ileus (9.1%), acute renal failure (4.5%) and pneumonia (4.5%). The perinatal mortality was 45.5%.Conclusion: Uterine rupture is a grave obstetric event with maternal and perinatal morbidity and commonly follows pregnancies with scarred uterus.

Published: September 2017

Background: Laparoscopic cholecystectomy is performed either by four port or three port. Although the overall patient outcome has been studied with comparable results, surgeon’s stress level has not been addressed commonly.Objective: To compare the difference in surgeon’s physical and mental stress between three port and four port laparoscopic cholecystectomy.Methods: This prospective randomized comparative study was carried out from January 2014 to August 2014 in patients undergoing laparoscopic cholecystectomy with American technique. Patients were randomized into four port laparoscopic cholecystectomy group and three port laparoscopic cholecystectomy group. Surgery was performed by experienced laparoscopic surgeons. At the end of procedure, surgeons were given questionnaire to evaluate physical and mental stress faced by them based on Visual Analogue Scale. The results obtained were compared.Results: Total 60 cases were evaluated, 30 in each group. Mean age of patients and American society of Anesthesiologists score were not different. Surgeon’s perception regarding physical and mental stress while performing in two different groups was analyzed. The difference is not statistically significant. Neither any of the three port group needed to add additional port nor any of the patients were converted to open surgery. None of the patient in either group developed clinically significant complication.Conclusion: Both the four and three port laparoscopic cholecystectomy techniques are comparable in regards to patient outcome as well as to the physical and mental stress experienced by the surgeons.

Published: September 2017

Background: Surgical complications represent a signifi cant cause of morbidity and mortality with the rate of major complications after inpatient surgery in industrialized countries. The purpose of this study was to summarize experience with surgical checklist use and efficacy for improving patient safety.Objective: To evaluate the compliance of implementation and outcome of World Health Organization Surgical checklist use in surgical practice at Kathmandu Medical College.Methods: This is a prospectively designed descriptive study including adult patients undergoing surgical procedure in Kathmandu Medical College Hospital from June 2013 till June 2014. Obtained data on compliance of World Health Organization safety checklist use by practitioner and its outcome in patient’s safety were assessed using SPSS version 15.The surgeries that underwent under local anesthesia were excluded from the study.Results: World Health Organization checklist was implemented in all 288 patients undergoing various surgical procedures with acceptable compliance by all 41 practitioners. Although it had no impact on correctable mortality and morbidity, frequent instrument malfunctions were offi cially recorded. Attitudes towards use of checklist was good as 100% of participants wanted use of checklist if they were having operation on themselves. However 22% of the participants complained of extra time needed to fi ll the checklist. Time taken to fi ll up sign in column of checklist was on average from 120 to 150 seconds (mean 135±5secs) and sign out was 80-100 seconds (mean 95±6secs). Only 69% of the participants were available for sign out. Scissor malfunction was detected in 4(1.38%) cases and operation theatre table related problem was found in one case (0.34%).Conclusion: Implementation of World Health Organization Surgical Safety Checklist can be done with acceptable compliance and instrumental malfunction was well documented.

Published: September 2017

Background: Bleeding oesophageal varices are a major complication of portal hypertension following liver cirrhosis. Child Pugh’s score has been used as a prognostic tool while managing a patient with liver cirrhosis.Objective: To clinically correlate Child Pugh’s score and oesophageal varices in upper gastrointestinal endoscopy in cirrhotic patient.Methods: This is a prospective descriptive study done from January 2014 to January 2015. Cirrhotic patients who were referred for upper gastrointestinal endoscopy with or without history of upper GI bleeding were included. Patients were categorized according to Child Pugh’s score into A, B, C and correlated with their endoscopic finding of grading of varices.Results: A total of 50 cirrhotic patients underwent upper gastrointestinal endoscopy during one year. Out of which 60% were in Child Pugh’s category A, 30 % in category B and 10 % in category C. Among them 62% had grade I varices, 20% had grade II varices and 18 % had grade III varices. Those who presented with history of hematemesis had higher grades of oesophageal varices in comparison to those without hematemesis.Conclusion: Cirrhotic patients with higher Child Pugh’s score had higher grades of oesophageal varices leading presentation with hematemesis. Hence, routine screening of cirrhotic patient is necessary before the development of varices.

Background: The human facial contour has always been an interesting subject for anatomists, anthropologists, plastic surgeons and artists. The purpose of study was to create and evaluate data on face anthropometry.Objectives: To determine total facial index in medical students and to compare these with the data from other population for use in forensic, archaeological studies, anatomy and plastic surgery.Methods: This is a descriptive study. A total of one hundred and forty medical students, presently studying at Kathmandu Medical College, aged between eighteen and twenty four years were selected as the subjects for the present study. Among the one hundred and forty students, forty four were female and ninety six were male. Two measurements:morphological facial length and bizygomatic breadth were taken by using spreading calibre.Results: The mean morphological facial length was 110.7mm with a standard deviation of 5.98mm in males and 102.1mm in females. Bizygomatic breadth was 130.8 mm in males & 123.5mm in females. The facial index (mean) was 86.09 in males and 84.84 in females.The dominant type of face shape in males was mesoproscopic (48.66%) followed by euriprosopic (23%), leptoprosopic (13.33%), hypereuriprosopic (13%) & hyperleptoprosopic (2%). In females the dominant type of face was also mesoprosopic (37%) followed by hypereuriprosopic (22%), euriprosopic (20.33%), leptoprosopic (19%) and hyperleptoprosopic (1.66%).Conclusion: The dominant phenotype in the studied population was mesoprosopic. The data obtained may be useful in anthropological research, forensic, genetic research, as well as in medical clinical practice.
Infrared Spectra of the Ices at ≈4 K and the Interpretation of the vOD(D2O) Bands of Ices II and IX
Authors: Bates F. E. , Jacobs S. M. , Bertie J. E. 
Published: September 2017

AbstractWe have studied the infrared absorption by the OD stretching, vOD(D2O), and D2O rotational, vR(D2O), vibrations of fully deuterated ice II and ice IX at lo K, and the absorption by OD stretching vibrations, vOD (HDO), of HDO molecules isolated in ices Ih, II, and IX at 10 K. Calculations of the frequencies and relative intensities of the zero-wave-vector normal vOD(D2O) vibrations of ices II and IX have allowed the vOD(D2O) absorption to be assigned. Each component of the band is broad, even at 10 K, most probably because of Fermi resonance between the fundamental OD stretching vibrational states and the isoenergetic continuum of high-order overtone and combination states of the lattice modes. This work has yielded the most complete interpretation yet achieved of an infrared band due to the OH or OD stretching vibrations of a phase of ice.The far-infrared absorption by the translational vibrations of H2O and D2O ices Ih and Ic at 4.3 K has been measured, and has revealed differences between the spectra of ices III and Ic for the first time.Papers describing this work in full have been published in Journal of Chemical Physics, Vol. 67, No. 4, 1977, p. 1311-18, and Vol. 67, No. 6, 1977, p. 2445-48.
Lichen Growth on Supraglacial Debris and its Implications for Lichenometric Studies
Authors: Griffey Nigel J. 
Published: September 2017

AbstractLichens were found growing on some of the supraglacial debris of six small, active, retreating valley glaciers in southern Norway. The circumstances permitting their growth are discussed, as is the possibility of their surviving pro-glacial deposition under current and past conditions. Their occurrence does not appear to present a problem to careful lichenometric surveys of Holocene glacial and fluvio-glacial deposits.
The Col-Gully and Glacial Deposits at Court Hill, Clevedon, Near Bristol, England
Authors: Gilbertson D. D. , Hawkins A. B. 
Published: September 2017

AbstractAn outline is given of the Quaternary geology and geomorphology of Court Hill Col in Failand Ridge near Clevedon, Avon County, from observations made during the construction of the M5 Motorway.A glacial col-gully about 100 m wide and approximately 25 m deep is described. The col-gully, eroded through the Carboniferous Limestone, opens and deepens northward. Associated with the Col and the col-gully is a complex sequence of Quaternary deposits. Uppermost in the sequence is a layer of red sandy silt (cover sand) approximately 0.5 m thick, of periglacial origin, probably of Devensian (Weichselian) age. Largely confined to the col-gully are unstratified tills, stratified ice-contact deposits and glacio-lacustrine deltaic deposits. The glaciogenic deposits are up to 25 m thick. Boulders of about 8 Mg in weight have been observed.The geomorphology of the col-gully, and the stratification and composition of the glaciogenic deposits, demonstrate that an ice sheet at least 85 m thick had impinged against the south flank of Failand Ridge and was discharging immense quantities of water and sediment down an ice-contact slope through the Col into a small ice-marginal lake north of the col-gully. The ice sheet is regarded as being Wolstonian, or Anglian, in age.The precise origins of the col-gully and the interpretation of the glacial sequence are not yet completely clear. However, it is believed that the balance of evidence indicates that both the col-gully itself and the glaciogenic deposits represent a complex sub-, en- and pro-glacial sequence associated with the downwasting and division of an ice mass into two parts by the "emergence" of Failand Ridge. The possible extent and geomorphological implications of ice-sheet penetration into the Bristol area are briefly discussed.
The Difficulties of Measuring the Water Saturation and Porosity of Snow
Authors: Colbeck S. C. 
Published: September 2017

AbstractLiquid saturation and porosity control most of the important material properties of wet snow, hence accurate measurements of these two parameters is of the utmost importance for both field research and glaciological applications. For example, the movement of liquid water through snow is highly sensitive to the volume of water present and accurate measurements of the water saturation are necessary in order to infer the temporal and spatial variations in the flow field. Nevertheless, most of the instruments in use are not capable of making accurate determinations of saturation.An error analysis shows that only direct measurements of the liquid volume can provide accurate values of water saturation, hence the melting calorimeter is inherently inaccurate. While centrifuges extract some of the liquid for direct measurement, there is always some residual liquid left depending on the grain size and structural parameters of the ice matrix. Therefore, some uncertainty exists over the interpretation of the data obtained from centrifuges. High-frequency capacitance probes can be used either in situ or on the surface and are very sensitive to the volume of liquid present. Capacitance probes are by far the best of the available devices. Remote-sensing techniques, like the active microwave system, require more development for use in operational forecasting schemes and as research tools.
Polar Firn Densification and Grain Growth
Authors: Alley Richard B. , Bolzan John F. , Whillans Ian M. 
Published: September 2017

A 50 m firn core from Dome C, East Antarctica, was found to consist of coarse firn, which comprised 90 to 95% of the core, and fine firn. Coarse firn was characterized by large crystals with a vertical shape orientation near the surface, connected to nearest neighbors by relatively large necks in a structure different from closest packing. Fine firn was of higher density and consisted of smaller, more spherical crystals connected by relatively narrow necks in a more nearly closest-packed configuration.Higher surface free energy in fine firn causes crystals and necks to grow more rapidly than in coarse firn. However, we find that coarse firn densifies more rapidly with time, contrary to the predictions of unconfined sintering models. Load-driven densification due to a power-law creep mechanism is found to account for the larger coarse-firn densification rate. However, if the exponent in the power law exceeds one, then densification rates are predicted to increase with depth due to increasing load, contrary to observed behavior. We speculate that different mechanisms may control the densification process in fine and coarse firn.
Present-Day Glaciation in the South Shetland Islands
Authors: Orheim Olav , Govorukha L.S. 
Published: September 2017

This paper presents mass-balance results from Deception Island for 1968–69 to 1973–74, from King George Island for the balance years 1969–70 and 1970–71, and from Livingston Island from 1971–72 to 1973–74.The accumulation areas of all localities are in the soaked fades, with a firn/ice transition at King George Island at 12 to 20 m depth. Of the glaciers studied, only “Gl” on Deception Island terminates wholly on land and has a relatively large ablation area.The mass-balance curves are similar for King George Island and Livingston Island, with equilibrium lines at around 150 m elevation. “Gl“ on Deception Island has more negative summer balances, and the equilibrium line ranged from 275 to 370 m during the six balance years. Here, there were no years of positive net mass balance, and large negative net values during the 1970–71 to 1972–73 balance years. This resulted from a lowered albedo caused by ash from the August 1970 eruption. Ash layers from the Deception Island eruptions are also observed on Livingston Island and King George Island, where they form stratigraphic markers in the accumulation areas of the glaciers.Annual balance variations from 1957–58 to 1970–71, based on stratigraphic studies at Deception Island and King George Island, show good correlations, indicating that the variations reflect changes in regional climate.
Anomalous Behaviour of Antarctic ice Cores Studied by Electrical and Mechanical Damping Measurements

Published: September 2017

In order to obtain new information concerning the anomalous properties of Antarctic ice previously observed through electrical measurements, we have studied specimens from a coastal site by means of internal friction measurements in the 1 Hz range. The results have been compared to previous ones obtained with polar ice from Dome C and electrical measurements have been made on the same samples in order to confirm the anomalous behaviour of such material.Two possible explanations of the anomalous properties of polar ice are discussed, namely the role of impurities and the ageing effect. It seems improbable that impurities could be responsible for such properties due to their low concentration. Some experiments, however, lead us to interpret the behaviour of polar ice in terms of modifications with time of the concentration and distribution of intrinsic point defects present at the beginning of the existence of the ice microcrystals
Radio Echo-Sounding Of Shirase Glacier And The Yamato Mountains Area

Published: September 2017

In 1979, the National Institute of Polar Research (NIPR) developed a 179 MHz airborne radio echo-sounder (NIPR-A), and installed it in a Pilatus Porter PC-6 aircraft. The peak power of the sounder is about lkW and the pulse width is 0.3 ys. Soundings were carried out in Antarctica on Shirase Glacier and the Yamato Mountains in January 1980. The total flight distance over the Shirase Glacier was about 500 km in six flights, while, on the Yamato Mountains area, about 80 km long, two north-south flights and three eastwest flights were carried out.In spite of poor wave penetration, the presence of many sub-glacial uplands (1 000 to 2 000 m a.s.l.) near the Yamato Mountains area was revealed. Discussion is concentrated on the bedrock and surface topography of the bare ice area near Motoi Nunatak in the southeast Yamato Mountains, because the previous traverse party covered this area and many meteorites have been discovered here.A high sub-ice ridge with three peaks extends east of Motoi Nunatak, and from 22 to 28 km east of Motoi Nunatak there is a short ridge with two peaks. From 12 to 20 km up-glacier from Motoi Nunatak, a long but comparatively low ridge surrounds Motoi Nunatak ridge like an arc. Finally, the sub-ice flow lines near Motoi Nunatak are deduced from new and earlier data.
