Delayed diagnosis of traumatic diaphragmatic hernia may cause colonic perforation: a case report

Early diagnosis of diaphragmatic rupture after traumas may be difficult, and delayed diagnosis may result in increased morbidity and mortality. This paper describes the case of a 32-year-old man who experienced a traffic accident and had diagnosis of traumatic diaphragmatic hernia nearly four months later. The patient was referred to our emergency room suffering from ileus symptoms. Physical examination demonstrated an apparent abdominal distention, tenderness at the upper abdominal quadrants, rebound, and defense. Thoraco-abdominal X-rays and computerized tomography imaging demonstrated intestinal segments with air-fluid levels in thorax. Laparotomy was performed after a preoperative diagnosis of a strangulated-diaphragmatic hernia. At abdominal exploration, it was found that transverse colon and omentum entered into thorax through diaphragmatic defect located at the left diaphragm. Herniating colon segment was complicated with ischemic necrosis and perforation. In conclusion, colon necrosis and perforation may develop when early diagnosis of diaphragmatic ruptures are missed

Breast cancer in association with thyroid disorders

BACKGROUND: The relationship between breast cancer and thyroid diseases is controversial. Discrepant results have been reported in the literature. The incidences of autoimmune and nonautoimmune thyroid diseases were investigated in patients with breast cancer and age-matched control individuals without breast or thyroid disease. METHODS: Clinical and ultrasound evaluation of thyroid gland, determination of serum thyroid hormone and antibody levels, and fine-needle aspiration of thyroid gland were performed in 150 breast cancer patients and 100 control individuals. RESULTS: The mean values for anti-thyroid peroxidase antibodies were significantly higher in breast cancer patients than in control individuals (P = 0.030). The incidences of autoimmune and nonautoimmune thyroid diseases were higher in breast cancer patients than in control individuals (38% versus 17%, P = 0.001; 26% versus 9%, P = 0.001, respectively). CONCLUSION: Our results indicate an increased prevalence of autoimmune and nonautoimmune thyroid diseases in breast cancer patients

Characterization of Flocs in Dewatering of Coal Plant Tailings

Flocculation is a widely used method for dewatering fine coal tailings. Flocs must resist to the shear stresses during the following processes such as flotation, cyclone separation, and pumping. Therefore, the strength of the flocs must be considered during flocculation. In this study, the fine coal tailings were dewatered with an anionic flocculant SNF-923 at various dosages, and the floc size of the coal tailings was characterized using a laser diffraction particle size analyzer with respect to time in order to determine the change in the floc size and hence the floc strength. The results of this study clearly indicated that the determination of the floc size with a laser particle size analyzer could be a simple and good method to observe the flocculation efficiency in terms of the floc strength

Ameliorative impacts of floral extract of Salvia species on oxidative stress and inflammation in rats renal ischemia/reperfusion

91-100I/R injury is a potentially serious problem that is encountered during a variety of medical and surgical procedures, such as thrombolytic therapy, organ transplantation and coronary angioplasty, The basic pathophysiology of I/R injury is microvascular dysfunction which is developed following reperfusion of ischemic tissues. It has clinical importance because of its frequent occurrence and mortality in some surgical conditions such as renal transplantation. Here, we investigated the protective effect of Salvia extracts on kidneys against I/R injury. Forty Spraque Dawley rats were divided into 5 groups. Right nephrectomy was performed to all groups. Gr. I, control; Gr. II, I/R; Gr. III & IV, I/R+50 and I/R+100 mg/kg Salvia floral extract; and Gr. V with I/R+50 mg/kg Rosmarinic acid. Salvia and Rosmarinic acid for 7 days was given single dose as a gavage.60 min ischemia, 60 min reperfusion were applied to groups except control. Intracardiac blood samples were taken, Blood urea nitrogen, creatine, malondialdehyde, myeloperoxidase, nitric oxide and chitotriosidase levels were detected. Mean values were evaluated by statistical analysis. The renal tissues were examined under light microscopy. Based on our biochemical and histological data, Salvia floral extract has potent anti-inflammatory and antioxidant effects against renal structure and function

Results of paclitaxel (day 1 and 8) and carboplatin given on every three weeks in advanced (stage III-IV) non-small cell lung cancer

BACKGROUND: Both paclitaxel (P) and carboplatin (C) have significant activity in non-small cell lung cancer (NSCLC). The weekly administration of P is active, dose intense, and has a favorable toxicity profile. We retrospectively reviewed the data of 51 consecutive patients receiving C and day 1 and 8 P chemotherapy (CT) regimen in advanced stage NSCLC to evaluate the efficacy and toxicity. METHODS: Patients treated in our institutions having pathologically proven NSCLC, no CNS metastases, adequate organ function and performance status (PS) ECOG 0–2 were given P 112.5 mg/m(2 )intravenously (IV) over 1 hour on day 1 and 8, followed by C AUC 5 IV over 1 hour, repeated in every three weeks. PC was given for maximum of 6 cycles. RESULTS: Median age was 58 (age range 39–77) and 41 patients (80%) were male. PS was 0/1/2 in 29/17/5 patients and stage was IIIA/IIIB/IV in 3/14/34 patients respectively. The median number of cycles administered was 3 (1–6). Seven patients (14%) did not complete the first 3 cycles either due to death, progression, grade 3 hypersensitivity reactions to P or lost to follow up. Best evaluable response was partial response (PR) in 45% and stable disease (SD) in 18%. Twelve patients (24%) received local RT. Thirteen patients (25%) received 2nd line CT at progression. At a median follow-up of 7 months (range, 1–20), 25 (49%) patients died and 35 patients (69%) progressed. Median overall survival (OS) was 11 ± 2 months (95% CI; 6 to 16), 1-year OS ratio was 44%. Median time to progression (TTP) was 6 ± 1 months (95% CI; 4 to 8), 1-year progression free survival (PFS) ratio was 20%. We observed following grade 3 toxicities: asthenia (10%), neuropathy (4%), anorexia (4%), anemia (4%), hypersensitivity to P (2%), nausea/vomiting (2%), diarrhea (2%) and neutropenia (2%). Two patients (4%) died of febrile neutropenia. Doses of CT were reduced or delayed in 12 patients (24%). CONCLUSIONS: P on day 1 and 8 and C every three weeks is practical and fairly well tolerated outpatient regimen. This regimen seems to be comparably active to regimens given once in every three weeks

Distributed Self-Stabilizing Capacitated Maximal Independent Set Construction in Wireless Sensor Networks

WOS: 000540974700001Wireless sensor networks (WSNs) are composed of a large number of wireless self-organized sensor nodes connected through a wireless decentralized distributed network without the aid of a predefined infrastructure. Fault-tolerance and power management are fundamental challenges in WSNs. A WSN is self-stabilizing if it can initially start at any state and obtain a legitimate state in a finite time without any external intervention. Self-stabilization is an important method for providing fault-tolerance in WSNs. Maximal independent set (MIS) is an extensively used structure for many important applications such as clustering (Randhawa and Jain in Wirel Personal Commun 97(3):3355, 2017. 10.1007/s11277-017-4674-5) and routing (Attea et al. in Wirel Personal Commun 81(2):819, 2015. 10.1007/s11277-014-2159-3; Lipinski in Wirel Personal Commun 101(1):251, 2018. 10.1007/s11277-018-5686-5) in WSNs. the capacitated MIS (CapMIS) problem is an extension of MIS in that each node has a capacity that determines the number of nodes it may dominate. in this paper, we propose a distributed self-stabilizing capacitated maximal independent set algorithm (CapMIS) in order to reduce energy consumption and support load balancing in WSNs. To the best of our knowledge, this is the first algorithm in this manner. the algorithm is validated through theoretical analysis as well as testbed implementations and simulations.TUBITAK (Scientific and Technical Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [215E115]The authors would like to thank TUBITAK (Scientific and Technical Research Council of Turkey) for the project grant (Project Number 215E115)

An Asynchronous Self-Stabilizing Maximal Independent Set Algorithm in Wireless Sensor Networks Using Two-Hop Information

International Symposium on Networks, Computers and Communications (ISNCC) -- JUN 18-20, 2019 -- Istanbul, TURKEYArapoglu, Ozkan/0000-0001-7309-7948WOS: 000520478600097Maximal independent set (MIS) has significantly important in practical applications for wireless sensor networks (WSNs). A distributed self-stabilizing system can initially start at any illegal state and takes back a legal state as long as there is no external intervention. We propose a novel distributed self-stabilizing MIS algorithm using two-hop information. It stabilizes an unstable system at most n-1 moves under an unfair distributed scheduler where n is the number of nodes in the graph. We use the message passing model as the communication model where this model is very appropriate for WSNs. the communication consumes the most energy in WSNs. So, move count is at least as important as round count where reducing the move count prolongs the lifetime of the network. We analyzed theoretically and tested it on SimPy discrete event simulator on randomly generated connected simple undirected graphs to compare with its counterparts in terms of transmitted bit count and move count against various node degrees and node counts.IEEE, IEEE Commun Soc, TEST, CIS ARGE, AI
