Feto-maternal outcome in previous one cesarean section: a retrospective observational study at a district hospital of Jharkhand

Background: Cesarean section is one of the most common surgery done in department of obstetrics and gynecology. It becomes more complicated in cases of high risk pregnancy like PIH, APH etc. Its rate is increasing day by day. Once a CS, always a CS, is questionable but being followed up at various set up due to various reasons. Today, one of the important indications of repeat CS is previous CS which increases the rate of CS in a particular set up and morbidities associated with multiple CS. According to ACOG guidelines, VBAC should be attempted to decrease the incidence of repeat CS and morbidity among them. This study was conducted to analyze the incidence of subsequent CS in previous one CS cases, demographic variables and feto-maternal outcome in previous CS patients.Methods: This was a retrospective observational study on previous CS patients, carried out in District hospital, Dumka, Jharkhand. The rates, demography and feto-maternal outcome among previous one CS patients were studied during 1 year duration and data was obtained from labor room and medical record department.Results: Out of 2947 deliveries, 63 patients had previous one cesarean section, the incidence being 2.13%. 39.7% deliver vaginally while 60.3% needed repeat cesarean section. Majority (95.2%) were in 21-30yrs age group, 76.2% were unbooked and 25.4% were tribal population. Maximum (79.4%) were gravid 2 and 93.7% were term. 93.7% had birth space >18 months. Out of 38 repeat cesarean section, 78.9% underwent emergency cesarean section. The most common indication being scar tenderness (39.5%) followed by CPD (15.8%). Intraoperatively, severe adhesions found in 15.8% cases, bladder adherence in 18.4% cases and 2.6% had adherent placenta. PPH occurred in 4.8% cases and blood transfusion or injectable iron therapy required in 25.4% cases. 4.7% had wound infection, 7.9% had prolong hospital stay and 22.2% cases required prolong foley’s catheterization. There was no maternal mortality. 95% babies born alive, 3.2% was stillbirth, 1.5% was IUD and the neonatal death rate was 3.2%.Conclusions: Previous cesarean section is one of the most important causes of CS in subsequent pregnancies, hence increase in the rates of CS and the morbidities associated with multiple CS among mothers. Thus the decision of CS in primigravida should be taken wisely and practice of CS on demand should be discouraged.

Strategies to Maximize the Wood Production in Amazon Forest

BackgroundThis study aimed to develop a procedure to determine which logging diameter would achieve optimal wood production by species, aiming to support sustainable management of the Amazon forest. Two main methodologies of analysis by species were combined: probability density function (PDF) and growth modeling. The growth models were used to derive the volume increment curves at the individual tree level. To detect the points of maximum annual increment in volume at the population tree level we used PDF with adjusted growth equations.ResultsThe population maximum annual volumetric increments occurred in smaller diameters compared to that of the individual-level. When combining shorter cutting cycles with the population biological rotation point considered as the minimum cutting diameter (MCD), we observed higher annual increments in volume than that achieved using the Brazilian law criteria (MCD = 50 cm) or other MCD tested.ConclusionThe procedure proposed may be used by forest managers and forest law-makers, aiming to maximize sustainable wood production in the Amazon forest.

Seasonal trends in ear, nose, throat and head, neck patients undergoing shortwave diathermy at a tertiary care centre of Punjab: a five-year study

Background: Shortwave diathermy, a therapeutic modality in acute inflammatory conditions of the ear, nose and neck has its utility in the paediatric, adolescent, middle age and the elderly. The seasonal variations of the patients enrolled in physiotherapy clinics for temporo-fascio-cervical diathermy sessions during a 5 years period, were analysed. Methods: 490 patients with inflammatory pathologies localized to the head and neck region and referred to the physiotherapy unit of a tertiary care centre of Punjab were analysed. All were subjected to shortwave diathermy. The subjects were analysed for any seasonal trends.Results: In the paediatric age group, maximum patients were observed in the month of March over the period of 5 years followed by the month of January. In the adolescent population maximum patients were observed in the month of November over the period of 5 years followed by the month of December. In the Adult population maximum patients were observed in the month of April over the period of 5 years followed by January and August.Conclusion: Paediatric patients came for regular sittings in the end of March end, i.e. post examination vacation period. The elderly visited mostly during winters. Malignant otitis externa with underlying diabetes worsens in winters due to increase in intake of sugary energy drinks.

After Cahokia: Indigenous Repopulation and Depopulation of the Horseshoe Lake Watershed AD 1400–1900

The occupation history of the Cahokia archaeological complex (ca. AD 1050–1400) has received significant academic attention for decades, but the subsequent repopulation of the region by indigenous peoples is poorly understood. This study presents demographic trends from a fecal stanol population reconstruction of Horseshoe Lake, Illinois, along with information from archaeological, historical, and environmental sources to provide an interpretation of post-Mississippian population change in the Cahokia region. Fecal stanol data indicate that the Cahokia region reached a population minimum by approximately AD 1400, regional population had rebounded by AD 1500, a population maximum was reached by AD 1650, and population declined again by AD 1700. The indigenous repopulation of the area coincides with environmental changes conducive to maize-based agriculture and bison-hunting subsistence practices of the Illinois Confederation. The subsequent regional depopulation corresponds to a complicated period of warfare, epidemic disease, Christianization, population movement, and environmental change in the eighteenth century. The recognition of a post-Mississippian indigenous population helps shape a narrative of Native American persistence over Native American disappearance.

Bactericidal, protistocidal and nematodicidal properties of mixtures of alkyldimethylbenzyl ammonium chloride, didecyldimethyl ammonium chloride, glutaraldehyde and formaldehyde

We conducted a comparative analysis of the impact of disinfecting preparations on the cryogenic stains of microorganisms, and also on Haemonchus contortus (Rudolphi 1803), invasive larvae of the ruminants. To test the preparations for disinfection, we used laboratory analyses with methods of biotesting, particularly with the use of Paramecium caudatum Her., Tetrahymena pyriformis Ehrenberg. We researched mixtures of substances: alkylbenzyldimethylammonium chloride (C24H42IN, BAK, mixture of homologues alkylbenzyldimethylammonium chloride and with n-C12H25, n-C14H29 and n-C16H33), didecyldimethylammonium Chloride (DDAC, C22H48ClN) and glutaraldehyde (C5H8O2); formaldehyde (CH2O), alkylbenzyldimethylammonium chloride and glutaraldehyde in 1% have bactericidal properties for the following cryogenic strains of microorganisms: Staphylococcus аureus, Salmonella typhimurium, Escherichia coli, Listeria monocytogenes, Proteus vulgaris, Serracia marcescens, Pseudomonas аeruginosa, Enterococcus faecalis and Yersinia enterocolitica. The Bacillus сereus were affected by the preparations bacteriostatically: we observed growth in the colonies in the medium with addition of 1% solution of mixture of alkylbenzyldimethylammonium chloride and didecyldimethylammonium chloride, and also 1%, 5% and 10% of solution of mixture of glutaraldehyde, formaldehyde and alkylbenzyldimethylammonium chloride. Also, these mixtures of substances have nematocidal properties. Death of 100% of L3 H. contortus after 24 hour exposure was observed with use of 1% solution of mixture of alkylbenzyldimethylammonium chloride and didecyldimethylammonium chloride, and also 5% glutaraldehyde, formaldehyde and alkylbenzyldimethylammonium chloride. Effective disinfection measures perform a leading role in providing stable veterinary well-being of livestock and healthcare of the population. Maximum toxicity during usage of the mixtures on P. caudatum was observed for the mixture of alkylbenzyldimethylammonium chloride and didecyldimethylammonium chloride, and also for formaldehyde and glutaraldehyde. The lowest toxicity for T. pyriformis was observed with use of the mixture of glutaraldehyde, sodium dodecylsulfate (SDS) and oleum terebinthini, and also the mixture of formaldehyde and glutaraldehyde, the highest formaldehyde and alkylbenzyldimethylammonium chloride. Thus, the most promising mixtures for use in veterinary medicine were determined to the following: alkylbenzyldimethylammonium chloride, didecyldimethylammonium chloride and glutaraldehyde, and also formaldehyde, alkylbenzyldimethylammonium chloride and glutaraldehyde.

Comparative development of sorghum, redgram and rice breeding population of Sitophilus oryzae (L.) feeding on cereals and split redgram dhal

Rice weevil Sitophilus oryzae (L.) mainly attacks whole grains such as wheat, corn, barley and rice and have been found actively breeding in such foods. The host range of S. oryzae now extended to split pulses. An experiment was carried out at the Entomology Laboratory, TNAU, Coimbatore during 2014-2015 to study the comparative development of sorghum, redgram and rice breeding population of S. oryzae feeding on cereals and split redgram dhal. The assessed parameters were survival percentage, per cent mortality and F1 progeny. The per cent mortality was higher in sorghum breeding population while feeding on redgram (98.33%) and rice (44.67%). In case of redgram breeding population per cent mortality was maximum in rice (21.67%) and sorghum (19.67%). The survival percentage was maximum in sorghum population while feeding on sorghum (95 %). F1 progeny emergence of sorghum breeding population was higher while feeding on sorghum (75.67%) and rice (36.67%). In case redgram breeding population F1 progeny emergence was maximum in redgram (62.33%) and sorghum (15.33%), whereas in rice breeding population maximum progeny emergence was observed in rice (72.33%) and sorghum (65.67%). The cereal bred population did not survive on redgram, whereas redgram bred population able to survive on cereals, but the progeny emergence and their development was affected.

Pattern of follicular development in sheep subjected to ovarian superstimulation after follicular ablation by laparoscopic ovum pick-up

ABSTRACT: The aim of this study was to determine the pattern of follicular development in ewes following ablation of all follicles associated with ovarian superstimulatory treatment. After confirmation of reproductive cyclicity using ultrasonography and progesterone levels, five adult ewes of undetermined breed received a vaginal pessary containing 60mg of medroxyprogesterone, maintained for 10 days, with the application of 100μg cloprostenol on the fourth day. On the tenth day, 300UI equine chorionic gonadotropin (eCG) was applied together with 80mg FSH, and all visible follicles were aspirated by laparoscopic ovum pick-up (LOPU). Following LOPU, ovarian structures were assessed using sonography every 8 hours for a period of 64 hours, and the number and diameter of small (<2.5mm), medium-sized (2.5-4.5mm), and large (>4.5mm) follicles were recorded. The average diameter of small follicles reduced from 5.6±1.5mm initially to 0.8±1.3mm by 56 hours. Population size of the medium-sized follicles during the observation period followed a parabolic distribution wherein the theoretical maximum size emerged at 34.6 hours with no difference at (P>0.05) 24 (4.6±1.5) and 48 hours (4.8±2.3). It was concluded that in ewes subjected to ovarian superstimulation immediately following LOPU, follicular development is characterized by a new wave of follicle growth with a predominance of medium-sized follicles (2.5-4.5mm) between 24 and 48 hours, and a theoretical population maximum occured at 34.6 hours.

Phylogeny, age structure, growth dynamics and colour pattern of the Salamandra algira algira population in the Edough Massif, northeastern Algeria

The distribution of the Fire Salamander in North Africa is discontinuous and the Edough Peninsula, Algeria, is considered as the eastern edge of the distribution area. In the current study, we establish a description of the Salamandra algira algira population in its type locality. In this context, an analysis of the mitochondrial DNA D-loop of 47 sequences comes to confirm the phylogenetic status of our population with regard to the other Algerian and Moroccan populations. Also, we used the skeletochronological method for establishing the age structure of the population. Maximum longevity reached 18 years, with a high frequency of young adults, which suggests a good survival of the juveniles. The growth of males is faster than that of the females, although the maximum size of the males is 180 mm, while that of the females is 210 mm. The Edough’s salamander’s phenotype is characterized by multiple small white spots dispersed in different parts of the body (belly, sides, legs and throat) and a high number of large red spots. These red spots are surrounded by a ring of small white spots on the lower part of the body and sometimes on the legs, thus creating specific eyespots that are often aligned along the lower sides.
