Abdominal pregnancy is a rare form of ectopic pregnancy with very high morbidity and mortality for both the mother and the fetus. Diagnosis and management can pose some difficulties especially in low resource centres. High index of suspi­cious is vital in making prompt diagnosis in such situations. A young lady of 30 years presented with 2nd gravida at 31 wks pregnancy with pain in the whole abdomen having loose motion admitted in Dept of Obs and Gynae BSMMU. She was diagnosed as a case of 31 wks pregnancy with gastroenteritis. She was treated conservatively according to advice of gastroenterologist and was discharged after improvement. Patient was readmitted again with pervaginal watery discharge. Decision for cesarean section was taken because of transverse lie, fetal growth restriction with severe oligohydramnios. After opening the abdomen, abdominal pregnancy was diagnosed. Following delivery of the baby significant bleeding started which was secured with ligature. Placenta was kept in situ. Mother and baby were discharged healthy on fourteenth postoperative day.

Abdominal pregnancy is a rare form of pregnancy but presents a very high risk of both morbidity and mortality for the fetus and mother. This situation is one of the most serious forms of ectopic pregnancy. The incidence of abdominal pregnancy varies, Rahman et al, get an incidence of 1 in 130,200 births. In the United States between 1970-1983 there were 10.9 abdominal pregnancies / 100,000 live births and 9.2 abdominal pregnancies / 1000 ectopic pregnancies. In laparotomy, placental management is the most difficult challenge, because it must be well prepared and planned. In this case report a 36-year-old woman with a diagnosis of gravid G2P1A0H1 27-28 weeks + Abdominal Pregnancy + Dead Fetus + Mild Anemia. Laparotomy is performed to deliver the baby, Durante surgery is carried out exploration of the placental attachment. Obtained the placenta embedded in the douglas cavum by attaching to the Ascendent Colon, Rectum, descending colon, intestine and peritoneum. It appears that some of the placenta has detached from its implantation, accompanied by a pile of stout cells. Removal of the placenta was carried out throughout the attachment site. The rest of the placenta is cleaned one by one by clamping with the clam punster slowly. Keywords: Abdominal Pregnancy, Dead Fetus, Laparotomy

Air Leak Syndrome

Neonatal pneumopericardium (PPC) is a rare form of neonatal air leak syndrome with high morbidity and mortality. Air leak syndrome in the newborn is usually associated with active resuscitation, respiratory distress syndrome, meconium aspiration syndrome, mechanical ventilation, or trauma associated with labour. Neonatal PPC can be associated with other air leak syndromes such as pneumomediastinum, pneumothorax, pneumoperitoneum, and subcutaneous and interstitial emphysema. Spontaneous PPC is a rare event in the neonatal period. We report a case of PPC in association with pneumothorax in a nonventilated term infant. The infant responded to thoracocentesis without the need for pericardiocentesis.

An experimental methodology was developed for estimating a very high cycle fatigue (VHCF) life of the aluminum alloy AMG-6 subjected to preliminary deformation. The analysis of fatigue damage staging is based on the measurement of elastic modulus decrement according to “in situ” data of nonlinear dynamics of free-end specimen vibrations at the VHCF test. The correlation of fatigue damage staging and fracture surface morphology was studied to establish the scaling properties and kinetic equations for damage localization, “fish-eye” nucleation, and transition to the Paris crack kinetics. These equations, based on empirical parameters related to the structure of the material, allows us to estimate the number of cycles for the nucleation and advance of fatigue crack.

A burst image sensor named Hanabi, meaning fireworks in Japanese, includes a branching CCD and multiple CMOS readout circuits. The sensor is backside-illuminated with a light/charge guide pipe to minimize the temporal resolution by suppressing the horizontal motion of signal carriers. On the front side, the pixel has a guide gate at the center, branching to six first-branching gates, each bifurcating to second-branching gates, and finally connected to 12 (=6×2) floating diffusions. The signals are either read out after an image capture operation to replay 12 to 48 consecutive images, or continuously transferred to a memory chip stacked on the front side of the sensor chip and converted to digital signals. A CCD burst image sensor enables a noiseless signal transfer from a photodiode to the in-situ storage even at very high frame rates. However, the pixel count conflicts with the frame count due to the large pixel size for the relatively large in-pixel CCD memory elements. A CMOS burst image sensor can use small trench-type capacitors for memory elements, instead of CCD channels. However, the transfer noise from a floating diffusion to the memory element increases in proportion to the square root of the frame rate. The Hanabi chip overcomes the compromise between these pros and cons.

A 73-year-old man presented with multiple lymphadenopathy. He had a 20-year history of palmoplantar psoriasis evolved to a diffuse erythrodermic picture in the last two years. Topic and systemic medications including prednisolone, acitretin, anti-IL17 (ixekizumab), TNF inhibitor (adalimumab), anti-IL23 (guselkumab), methotrexate, cyclosporine, and phosphodiesterase 4 inhibitor (apremilast) were ineffective. Repeated skin biopsies excluded mycosis fungoides, confirming psoriasis; molecular analysis of T-cell receptor genes ruled out clonality. The axillary lymph node histology documented a dermatopathic lymphadenitis, often associated with chronic cutaneous inflammatory diseases. At an accurate morphological evaluation, features of HHV8-positive multicentric Castleman disease were observed. Moreover, in a few follicles, in situ mantle cell neoplasia was identified. The translocation t(11;14)(q13;q32), characteristic of mantle cell lymphoma, and the monoclonal IGH gene rearrangement were present. HHV8 DNA was identified on plasma sample. Multicentric Castleman disease in psoriatic patients is a rare event and it might be favored by the immunomodulatory treatment in longstanding psoriasis. Multicentric Castleman disease patients are predisposed to developing simultaneous or subsequent lymphoma. In situ mantle cell neoplasia often behaves indolently, although it may progress to overt mantle cell lymphoma. Rituximab achieved a good control of psoriasis. Unfortunately, the patient developed Staphylococcus aureus sepsis for which he is currently on antibiotic therapy.

Many of the large number of underground works constructed or under construction in recent years are in unfavorable terrains facing unusual situations and construction conditions. This is the case of the subject under study in this paper: a tunnel excavated in evaporitic rocks that experienced significant karstification problems very quickly over time. As a result of this situation, the causes that may underlie this rapid karstification are investigated and a novel methodology is presented in civil engineering where the use of saturation indices for the different mineral specimens present has been crucial. The drainage of the rock massif of El Regajal (Madrid-Toledo, Spain, in the Madrid-Valencia high-speed train line) was studied and permitted the in-situ study of the hydrogeochemical evolution of water flow in the Miocene evaporitic materials of the Tajo Basin as a full-scale testing laboratory, that are conforms as a whole, a single aquifer. The work provides a novel methodology based on the calculation of activities through the hydrogeochemical study of water samples in different piezometers, estimating the saturation index of different saline materials and the dissolution capacity of the brine, which is surprisingly very high despite the high electrical conductivity. The circulating brine appears unsaturated with respect to thenardite, mirabilite, epsomite, glauberite, and halite. The alteration of the underground flow and the consequent renewal of the water of the aquifer by the infiltration water of rain and irrigation is the cause of the hydrogeochemical imbalance and the modification of the characteristics of the massif. These modifications include very important loss of material by dissolution, altering the resistance of the terrain and the increase of the porosity. Simultaneously, different expansive and recrystallization processes that decrease the porosity of the massif were identified in the present work. The hydrogeochemical study allows the evolution of these phenomena to be followed over time, and this, in turn, may facilitate the implementation of preventive works in civil engineering.

AbstractThe World Health Organization declared coronavirus infection 2019 (COVID-19) as a pandemic in March 2020. The infection with coronavirus started in Wuhan city, China, in December 2019. As of October 2020, the disease was reported in 235 countries. The coronavirus infection 2019 (COVID-19) is a disease with high morbidity and mortality. As of February 2021, the number of confirmed cases of COVID-19 globally is 102,942,987 and 2,232,233 deaths according to WHO report. This infection is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which is a ribonucleic acid (RNA) β-coronavirus. The infection is mainly transmitted through respiratory droplets.Healthcare workers (HCWs) play an essential role at the front lines, providing care for patients infected with this highly transmittable disease. They are exposed to very high occupational health risk as they frequently contact the infective persons. In order to limit the number of infected cases and deaths among healthcare workers, it is crucial to have better awareness, optimistic attitude, efficient PPE, and adequate health practices about COVID-19.

Objective. Pneumocephalus is a rare complication that often occurs after traumatic skull base injury, leading to morbidity and mortality. Material and Method. We present the case of a 42-year-old healthy man who injured himself when he stuck a metal stick into his left nasal cavity to relieve prolonged nasal obstruction. Immediate cerebrospinal fluid rhinorrhea and subsequent meningitis and pneumocephalus occurred later. He was presented at our hospital with fever and meningeal signs. Result. Computed tomography scans revealed left rhinosinusitis and air collection in the subarachnoid space. The patient received the conservative treatment of bed rest, intravenous hydration, head elevation, and broad-spectrum intravenous antibiotics. Pneumocephalus and meningitis resolved without any surgery, and he experienced no other sequela or complication. Conclusion. Pneumocephalus is a rare incidence and can lead to high morbidity and mortality. Prompt diagnosis and adequate treatment of pneumocephalus and meningitis proved beneficial for our patient who recovered without any complication or surgery.

Effective Representation

Summary We present a numerical simulation approach that allows incorporation of emulsion modeling into steam-assisted gravity-drainage (SAGD) simulations with commercial reservoir simulators by means of a two-stage pseudochemical reaction. Numerical simulation results show excellent agreement with experimental data for low-pressure SAGD, accounting for approximately 24% deficiency in simulated oil recovery, compared with experimental data. Incorporating viscosity alteration, multiphase effect, and enthalpy of emulsification appears sufficient for effective representation of in-situ emulsion physics during SAGD in very-high-permeability systems. We observed that multiphase effects appear to dominate the viscosity effect of emulsion flow under SAGD conditions of heavy-oil (bitumen) recovery. Results also show that in-situ emulsification may play a vital role within the reservoir during SAGD, increasing bitumen mobility and thereby decreasing cumulative steam/oil ratio (cSOR). Results from this work extend understanding of SAGD by examining its performance in the presence of in-situ emulsification and associated flow of emulsion with bitumen in porous media.

Very high asymmetric inductions result in the Pd-catalyzed intramolecular arylation of amides to give 3,3-disubstituted oxindoles when new in situ-generated chiral N-heterocyclic carbene (NHC*) ligands are employed. Structural studies show that conformational locking to minimize allylic strain is the key to understanding the function of these ligands. New applications of these ligands in the frontier area of asymmetric coupling reactions involving C(sp3)–H bonds are detailed. Highly enantioenriched fused indolines are accessible using either preformed- or in situ-generated Pd-NHC* catalysts. Remarkably, this occurs at high temperature (140–160 °C) via excellent asymmetric recognition of an enantiotopic C–H bond in an unactivated methylene unit.
