Summary. There is no doubt in the relevance of the problem of treatment of patients with unstable fractures of pelvic bones, since these injuries involve a threat to the patient's life in the early period and often lead to disability in the future. This article presents a rare case of treatment of a patient with an unstable pelvis injury, while being 16 weeks pregnant. Patient A., born 1993, was admitted after a road accident injury. The examinations included: X-ray, CT, ultrasound, and gynecologist consultation. The patient was diagnosed with closed bilateral fracture of the pubic and ischial bones with displacement; rupture of the left sacroiliac joint with the boundary fracture of the sacrum (61-С1.3 by the Tile-AO-ASIF classification). The patient was 16 weeks pregnant. The surgery – open reduction and extramedullary metalosteosynthesis – was performed at the 9th day after the injury. The patient was discharged to outpatient treatment at the 12th day after the surgery. She started walking on crutches 3 weeks after the surgery; no additional support was needed since 1.5 months after the surgery. The patient gave birth at 39 weeks by surgical intervention (caesarean section). The baby's condition was assessed as 8 according to the Apgar scale. At the control examination 10 months after the surgery, musculoskeletal function of the patient was fully restored.

SummaryThe purpose of this investigation was to study the accumulation of 87mSr in the proximal parts of the femoral bones of patients treated previously by external irradiation due to cancer of the uterine cervix. It was assumed that this method may be used in the future for the early diagnosis of postirradiation changes of bone (osteoradionecrosis).The incidence of postirradiation changes of the femoral neck among 5735 patients treated between 1950 and 1961 at the Department of Gynaecology of the Institute, was 0.8%. In the early period of postirradiation changes the patients complain only of pain and limitation of physical activities. If radiological and gynaecological findings were negative, the differential diagnosis between early recurrence and early osteoradionecrosis became impossible.49 selected patients were scanned after intravenous injection of 10—115 μCi of 87mSr per kg of body weight (0.5 up to 6.0 mCi). Illustrative cases of normal pelvic bones as well as postirradiation changes are presented and discussed. The authors conclude that the findings justify further systematic studies on the morphology of accumulation of 87mSr in the bones.

Spectral observations of low-mass X-ray binaries (LMXBs) show that the soft component usually dominates over the hard one. These results provide additional support to an interpretation based on models of LMXBs in which the neutron star while, on the average, spinning up, is also experiencing a spinning down torque. Under these conditions, a fraction of the luminosity associated with the gravitational release of energy on the surface of the accreting neutron star may manifest itself as luminosity originating in the inner part of the accretion disk. It is probably possible to separate the two contributions; the stellar luminosity can be associated with the hard component of the spectrum and the disk luminosity, related to the exchange of energy due to the torque between the rapidly spinning neutron star and the accretion disk, can be associated with the soft spectral component.

Careful History

Emergency room admissions and surgery secondary to the malfunctioning of devices intended for sexual stimulation are extremely common. Emergency room staff in the United States are commonly skilled in the detection and removal of some of these frequent occurrences. Occasionally, surgical intervention can be warranted if the device enters a cavity that cannot safely be explored in the emergency room setting. We report a case of a vibrator which was lost during sexual activity and appeared on flat plate X-ray to be in the abdominal cavity. A careful history showed that the device was of an unusually narrow diameter, and surgical intervention showed the device ultimately ended up in the bladder without traumatic injury. Following laparoscopic confirmation of the device’s location in the bladder, cystoscopic removal was performed and the patient recovered uneventfully.

Abstract Recent discovery of the X-ray neutral iron line (Fe  i Kα at 6.40 keV) around several supernova remnants (SNRs) show that MeV cosmic-ray (CR) protons are distributed around the SNRs and are interacting with neutral gas there. We propose that these MeV CRs are the ones that have been accelerated at the SNRs together with GeV–TeV CRs. In our analytical model, the MeV CRs are still confined in the SNR when the SNR collides with molecular clouds. After the collision, the MeV CRs leak into the clouds and produce the neutral iron line emissions. On the other hand, GeV–TeV CRs had already escaped from the SNRs and emitted gamma-rays through interaction with molecular clouds surrounding the SNRs. We apply this model to the SNRs W 28 and W 44 and show that it can reproduce the observations of the iron line intensities and the gamma-ray spectra. This could be additional support of the hadronic scenario for the gamma-ray emissions from these SNRs.

Stomach analyses showed that pink salmon fry fed mainly during daylight hours in the littoral zone of Departure Bay and Hammond Bay, British Columbia, in May. Although the diurnal feeding patterns of the fish differed slightly between the two bays, maximum mean prey biomass in the fishes' stomachs occurred near or at dusk in both bays. Daily rations consumed by Departure Bay and Hammond Bay fish were estimated to be 13.1 and 6.6% of their dry body weight, respectively. The fry consumed similar prey items in both bays, but in differing proportions. Harpacticoid copepods, copepod nauplii, and barnacle larvae comprised numerically 93.1 and 86.2% of the diets of Departure Bay and Hammond Bay fish, respectively. About 38% of the diet of Departure Bay fish and 51% of the diet of Hammond Bay fish comprised epibenthic prey, mainly harpacticoid copepods. The data provide additional support for the importance of the detritus-microbe-consumer type food chain supporting the production of pink salmon during their early period of marine residency.Key words: pink salmon, feeding behavior, daily rhythm, diet, ration, British Columbia

Objective: Patients at our institution with asymptomatic calyceal stones (<11 mm) are discharged to their GPs with a request for 12- and 24-month X-ray KUBs with specific re-referral criteria. We aimed to assess the effectiveness of this shared care protocol as well as to investigate long-term outcomes. Patients and methods: All patients satisfying the above criteria discharged during October 2009–June 2011 were reviewed for protocol compliance, symptomatic events and/or surgical intervention up to July 2015. Results: A total of 134 patients were identified. Out of 115 patients eligible for their first X-ray, and 100 patients eligible for their second X-ray, 43% and 26% respectively were performed. Of these, 75% demonstrated no progression. No patients were treated surgically solely on the basis of radiographic progression. Over a mean five-year follow-up, patients had a 39% chance of experiencing a symptomatic event and a 24% chance of requiring surgical intervention (ESWL, ureteroscopy and/or PCNL). Risk factors included a previous stone history and having a total stone size >10 mm. Conclusion: There was poor adherence to this protocol. Despite this, only symptomatic patients were treated surgically, challenging the value of indefinite surveillance of asymptomatic patients. Longitudinal studies are needed to determine a cost-effective manner in which these patients can be safely followed up.

Preoperative Procedures

In this study, we report our first experience of applying the concretion visualization method using augmented reality technology. A clinical case of a new surgical intervention on the parotid salivary gland with the localization of salivary stone in its parenchyma is considered. During additional diagnostics, it was found that the size of the concretion exceeds 5 mm which did not allow us to use the endoscopic technologies. That was the reason for the choice of surgical intervention external access using salivary stone visualization with the help of augmented reality. The preoperative procedures included making the upper jaw cast model, fitting the model and individual mouthguard with an X-ray contrast marker and marker slot. In addition to this, computed tomography of the head and neck using a mouthguard was made. During surgery under general anesthesia with nasal intubation, the mouthguard together with the marker is installed in the patient’s mouth and the surgeon puts on the glasses to visualize the stone image in place of its localization. This method enables to visualize the salivary stone on all surgery stages no matter what type of approach is used or performing hydropreparation. That is why using the augmented reality appears promising and is to be studied further.

Abstract Pectus excavatum is a chest wall deformity with an incidence of around 1 in 400 live births. The Nuss procedure is a surgical intervention that aims to restore functional integrity in these patients. We report the first case of bar migration into the stomach necessitating further surgical intervention for removal. Our case presents a rare complication of pectus excavatum repair and highlights the importance of vigilant follow-up in these patients. If bar migration does occur, imaging in the form of X-ray and CT scans may be of use in early detection in order to expedite management.

Cavernous sinus cavernous hemangiomas in pregnancy are extremely rare lesions. The precise management of these lesions remains unknown. The authors present a case of a cavernous hemangioma in pregnancy, centered within the cavernous sinus that underwent postpartum involution without surgical intervention. A 34-year-old pregnant patient (gravida 1, para 0) presented to an otolaryngologist with persistent headache and left-sided facial pain and numbness in the V1 distribution. While being treated for sinusitis, her symptoms progressed to include a left-sided oculomotor palsy and abducens palsy. Magnetic resonance imaging without contrast revealed an expansile mass within the left cavernous sinus consistent with a cavernous hemangioma. The patient was evaluated by a neurosurgeon who recommended close follow-up and postpartum imaging without surgical intervention. Although the lesion enlarged during pregnancy, the patient was able to undergo an uncomplicated cesarean section at 37 weeks. All facial and ocular symptoms resolved by 9 months postpartum, and MRI showed a decrease in lesion size and reduced mass effect. The authors conclude that nonsurgical management may be a viable approach in patients who have an onset or exacerbation of symptoms associated with cavernous sinus cavernous hemangiomas during pregnancy because postpartum involution may negate the need for surgical intervention.

What kind of role do the reactive aluminous has played during early hydration process of metakaolin-cement paste is investigated in present study. Therefore, metakaolin(MK) samples containing 45.94%, 22.86%, 0% reactive aluminous are prepared, respectively. In addition, X-ray Diffraction (XRD) analysis is employed to identify the crystalline phases of all specimens. The amount of acid-insoluble residue (AIR) of all specimens is used to evaluate the unreacted materials. The results obtained indicate that reactive aluminous can promote development of the early period strength significantly. Reactive silica and reactive aluminous reaction velocity was very slow during the first three days, then increased. The reaction velocity of reactive aluminous was faster than reactive silica between the first day and third day, but it shows an opposite result between the third day and seventh day.
