Calprotectin (CP) is an inflammatory marker. The aim of the current study was to investigate oxidative stress and changes in CP in cattle with traumatic reticuloperitonitis (TRP). The study was divided into two groups, experimental (TRP) and healthy control group, with 10 animals in each group. Total leucocyte count, neutrophil and lymphocyte counts were higher in the TRP group compared to the control group and this increase was statistically significant (P < 0.001). The level of malondialdehyde (MDA) in TRP group was statistically significantly higher than the control group (P < 0.001). The level of glutathione (GSH) in the TRP group was statistically significantly lower than in the control group (P < 0.001). Serum Amyloid A (SAA) and CP values were higher in the TRP group and this difference was statistically significant (P < 0.001). It was concluded as a result of ROC analysis that CP, which has similar values with SAA, can be used diagnostically to confirm the inflammatory status in cattle with TRP.
To provide a pictorial review of the main clinical applications of DECT with a focus on traumatic and non-traumatic emergencies.
DECT is becoming increasingly common in clinical practice. The differences in attenuation between two different datasets allow to perform a qualitative and quantitative characterization of the materials contained in a single voxel. Virtual monoenergetic images, material decomposition images, electron density maps, and atomic number maps are created by post-processing algorithms and offer the radiologist useful diagnostic data.
We present a series of cases illustrating the utility of DECT in the diagnosis and management of acute pathologies, with a special focus on musculoskeletal imaging and neuroimaging.
DECT is a useful imaging technique that may allow radiologists to make quicker and more precise diagnoses in the emergency setting.
This paper provides a detailed presentation of the estimated number of people in Hungary with eye disease and refractive errors by both sex and age.
In the past 12 years, 168,522 people (54.1% women and 45.9% men) have been screened under Hungary's Comprehensive Health Protection Screening Programme (MÁESZ).
The total number of people with eye disease in the adult Hungarian population (about 8 million people) is estimated to be 1,684,818, with women (1,078,026) outnumbering men (606,792). Eye diseases were found to be more common in older age groups, and more common in women than men in each age group. The estimated number of people with refractive errors in the Hungarian adult population is 5,005,095. The overall number of people with myopia in the adult Hungarian population is estimated to be 3,058,536, with roughly equal numbers of men and women. The majority of people with myopia (63.3%) are between 18 and 45 years of age.
The huge number of people in the Hungarian population affected by eye disease or refractive errors underscores the need to develop and implement an effective national strategy and specific programmes to prevent visual impairments.
Introduction: Orbital tumors are rarely occurring in significant
quantities apart from a few tertially referral centers, so statistically our
data represent national proportions and characteristics of the affected patient
group. Objective: Review of the tumor surgeries performed
during the first three and a half years of the Semmelweis University Orbital
Surgery Team (from February 2019 to August 2022). Analysis of the 94 operative
cases, mainly based on age distribution, tumor dignity, location, and the type
of surgery performed. Method: This is a retrospective study,
made by the review of the entire outpatient and surgical patient records of
three and a half years in our IT system. We collected and classified the
patients’ data according to various aspects, then compared our results to
international publications. Only patients with histologically confirmed cancer,
operated by colleagues of our workgroup between February 2019 and September
2022, were included in our analysis. Excision of skin lesions affecting only the
dermis and subcutaneous tissues, removal of circumscribed conjunctival cysts,
and enucleations were excluded from the examined patient group. This is how we
dealt with the significant number of orbital surgeries in which the presence of
tumor cell proliferation was not confirmed after biopsy.
Results: During the three and a half year period, 94
operations were performed due to intraorbital tumor involvement. The surgeries
were preceded by physical examination and imaging. We performed biopsy in 38.3%
(n = 36), tumor mass reduction in 18.1% (n = 17), complete removal in 43.6% (n =
41) of the cases. Based on the histological findings, 53.2% (n = 50) of the
tumors were benign and 46.8% (n = 44) were malignant. The average age was 60.5
years in the malignant, and 39.5 years in the benign group. The most common
benign tumor was cavernous hemangioma in 13.8% (n = 13), and the most common
malignant tumor was lymphoma in 31.9% (n = 30). Discussion:
Benign tumors can mostly be removed in toto, without residual
symptoms. In the case of malignant tumors of the orbit, often only the reduction
of the tumor mass can be achieved. In significant amount of cases, we plan to
take a biopsy based on their morphological characteristics and the anamnesis.
This is how we proceed in the case of lymphoma, the therapy of which is
conservative. Conclusion: Various tumors can affect the orbit.
In our publication, we process the data of 94 patients with intraorbital tumor
surgery. 53.2% of the tumors were benign and 46.8% were malignant. The rate of
malignant tumors increased with age, and lymphoma is by far the most common of
them. 70% of the benign tumors were either vascular, lymphatic or peripheral
nerve tumors or dermoid cysts. Benign tumors proved to be completely resectable
in 76% of the cases. Orv Hetil. 2023; 164(49): 1947–1953.
Introduction: The rapid development of minimally invasive
techniques did not leave neurosurgery untouched either. New surgical
interventions, both skull and spine surgery, are gaining more and more
popularity. Due to the aging society, previously inoperable degenerative
abnormalities are also receiving more and more attention. In the treatment of
spinal canal stenosis caused by degenerative changes, the initially used
laminectomy was replaced by unilateral “over-the-top” surgery, and in recent
years, by techniques that ensure the least possible collateral tissue damage,
such as tubular retractor and then spinal endoscopy. Objective:
The purpose of this study is to use the experiences of the past years to present
the decompression surgeries performed with two minimally invasive techniques,
i.e., the tube explorer and the endoscope, and their
results, providing an insight into international spine surgery trends.
Method: From January 1, 2022 to December 31, 2022, we
operated 43 patients with spinal canal stenosis using this techniques. In 27 of
these cases, we used a tube retractor and a microscope, while in 16 cases, we
used an endoscopic technique. In order to evaluate the results, we took a visual
analogue scale value before and after the intervention to evaluate neurogenic
claudication, lower back pain that worsens with exercise, and radicular pain at
rest. Based on this, the patients were divided into four groups: using unchanged
(0–30%), moderate (31–50%), good (51–75%) and excellent (76–100%) ratings. We
separately analyzed surgeries for stenosis combined with spondylolisthesis. We
evaluated our short-term results based on the average value of hospitalization
days. Results: We achieved excellent postoperative results for
all examined symptoms, i.e., neurogenic claudication in 95.3%,
lower back pain in 72.4%, while the symptoms of restlessness disappeared almost
completely in 86.9% of the cases. Accordingly, we experienced good and moderate
results in much smaller proportions. The results after decompression surgery for
spinal canal stenosis caused by spondylolisthesis were evaluated separately,
based on which the postoperative results of neurogenic claudication in 92.8% of
cases, low back pain in 70%, and pain at rest in 100% proved to be excellent.
The average number of the hospitalisation days was 3.7. Discussion and
conclusion: Our experience is in line with the international
results, which suggest that the results of minimally invasive techniques using
the tube explorer and the endoscope can be further improved both in the short
and long term. With the introduction of new techniques, we not only offer our
patients a less invasive approach with better results, but due to the efficiency
of the procedures, more patients can undergo surgery in a shorter time. Orv
Hetil. 2023; 164(49): 1926–1937.
Introduction: Cardiac implantable electronic device-related
complications may require transvenous lead extraction. Data on procedure
complexity and outcomes are derived from international registries. However,
patient characteristics vary considerably between countries.
Objective: To summarize the results of the 10-year
systematic institutional extraction program and compare it with international
data. Methods: We retrospectively analyzed consecutive patients
undergoing extraction between 2012 and 2020. Data regarding patient
characteristics, indications, techniques and outcomes of the procedures were
collected and compared with the results of the largest comprehensive European
registry (ELECTRa). We also examined success rates at different levels of the
“stepwise approach”. Results: 200 patients (65 ± 14.3 years,
74.5% male) were included. The indication of extraction was predominantly
infectious, exceeding the rate reported in ELECTRa (87.5% vs.
52.8%, p<0.001). Lead dwelling time was also longer in our study (7.8 ± 6.2
vs. 6.4 ± 5.4 years). The number of passive fixation leads
was found to be also significantly higher (62.2% vs. 46.6%,
p<0.001). One fifth of our patients had previously undergone a failed
extraction attempt. A higher proportion of patients required the use of locking
stylets (81.9% vs. 71.1%, p<0.001) and active extraction
sheaths (71.8% vs. 27.1%, p<0.001). Major complications
occurred in 4.5% and procedural death in 4 cases (2%). Procedural success was
88.2%, which is lower than the 95.7% reported in ELECTRa. In the stepwise
approach analysis, cumulative clinical success rate was 24.8% with locking
stylets, 74.2% with the primary active sheaths, 91.3% with advanced extraction
techniques (crossover, femoral snare) and 96.6% with non-emergency cardiac
surgery. Discussion and conclusion: In the last 10 years, a
successful lead extraction program has been developed in our institution.
Patient risk and procedure complexity far exceed those reported by international
registries. To achieve optimal outcomes, the availability of diverse extraction
techniques, experience as well as close educational and referral cooperation
with implanting centers are essential. Orv Hetil. 2023; 164(49): 1954–1964.
Introduction and objective: Laparoscopic complete mesocolic
excision (CME) with central vascular ligation is gaining acceptance for the
treatment of right colon cancers, however, variable mesenteric vascular anatomy
can be a surgical challenge, thus affecting results. The aim of our study is to
investigate the usefulness of a 3D virtual vascular model reconstructed from
CT–angiography. In this article, we demonstrate the application of 3D technology
in a surgical area difficult to comprehend with conventional techniques.
Method: In this randomized, controlled trial, we plan to
enroll 40 patients with AJCC stage I–III right colonic cancer scheduled for
laparoscopic CME surgery. Patients are randomized preoperatively one-to-one. The
experimental group (A) has a 3D virtual vascular model created for pre- and
intraoperative use, the control group (B) has no model available. Demographics,
blood loss, vascular injuries, procedure duration, lymph node harvest, specimen
quality, postoperative complications and length of stay are recorded. Surgeons
rate the model postoperatively on a 0–10 scale. Long term oncologic outcomes
will be recorded. Results: At submission of the abstract, 29
patients were enrolled (A = 18, B = 11). Demographics in the two groups are
comparable. Blood loss (p = 0.40), conversion rate (p = 0.75), postoperative
complications (p = 0.82) and hospital stay (p = 0.40) do not show significant
difference, while lymph node yield (p = 0.76) and specimen quality are also
comparable. Duration of standard surgical steps of central vascular ligation are
comparable. Surgeons rate the overall usefulness of the 3D model 7.6/10, with
the highest scores given for identifying ileocolic vessels (7.8) and Henle’s
trunk (8.3). The model was rated less useful for assisting gastroepiploic
dissection (5.2). No patient dropout occurred to this date.
Conclusion: Surgeons appraise the quality and usefulness of
the model positively, especially for identifying ileocolic vessels and the
anatomy of Henle’s trunk. Orv Hetil. 2023; 164(49): 1938–1946.
Primary hypertrophic osteoarthropathy (HOA) is a rare condition with no identifiable cause, accounting for 3%–5% of all HOA cases. It is challenging to identify incomplete primary HOA, which can be misdiagnosed as other hypertrophic periostitis diseases. At least two of the four criteria set by Borochowitz and Rimoin (1990) must be present to diagnose primary HOA. Diagnostic difficulties due to incomplete or atypical manifestations are common. We present a case of incomplete primary PHOA at Hanoi Medical University Hospital in Vietnam. A 37-year-old male presented with ankle joint pain for nearly four years. X-ray and magnetic resonance imaging showed periostitis in the tibias and fibulas, which could not exclude Camurati–Engelmann disease. Finally, gene sequencing on the Illumina MiSeq system identified a missense mutation (c.295C>T) in the solute carrier organic anion transporter family member 2A1 (SLCO2A1) gene on chromosome 3. Our case report and literature review aim to improve specialists' understanding of incomplete primary HOA and reduce the frequency of missed diagnoses.
The Tangut character
'ja¹ (#1718) is usually glossed as Chin. nuò 诺 ‘(to) promise; yes’ in dictionaries. Given the fact that it does occur in rhetorical questions, this article argues that Tangut
'ja¹ is instead a constituent question particle and thus not restricted in rhetorical use. The conclusion is based on a detailed philological investigation, employing multilingual parallel texts where applicable. Comparisons with other Qiangic languages reveal several candidates for cognates. Nonetheless, their similarity is more likely to be an areal typological feature, rather than an etymological relation.
The paper examines some features of Chekhov’s early poetics (1880–1885) in comparison with the newspaper as a discourse contemporary to his time. In the first half of the 1880s, the daily newspaper emerged as the dominant organ in the new system of the press. This was also the birth of mass communication in Russia, a necessary part of which was the emergence of “the small press”, i.e. the sphere of humorous journals, thin magazines, and daily newspapers in which Chekhov began to publish his works.
The paper also summarizes the outcomes of the studies that reconstructed the cultural space of Russian newspapers and magazines of the period in question. The concept of “newspaper discourse” is introduced for the purposes of comparison and understood in the paper as a new and unified space that aims towards a universal modelling of the world through the production of texts. Newspaper discourse as a term is different from the concepts of “the small press” and “journalism”. At the end of the first part, the paper discusses the notions of discursive practice and interdiscursivity as one of the types of intertextuality defined by N. Fairclough.
The second part summarizes the typology created by A. Stepanov for Chekhov’s early texts based on mixing or displacing statements of different speech genres. Using this typology, the paper identifies the humorous texts in which newspaper speech genres are used. In comparison with the practice of newspapers, the most interesting structural type is the metonymic arrangement of utterances belonging to different speech genres or those belonging to the same speech genre. In these cases, the juxtaposed statements also lack a common referent. I. Sukhikh argues that it is a demand by newspapers and magazines of that time that manifests itself in the principle of metonymic ordering of trifles (creating cycles, series, and lists). Thoughts of Readers of Newspapers and Magazines and A Memo are interpreted as humorous pieces built on the principle of a list, mocking the common practice of newspaper discourse: its ambition for universality.
In the two humorous pieces, an element of parodic interdiscourse is highlighted: the composition is based on the principle of a list. This structural type leads, more in Chekhov’s creative evolution in general terms, to more complex, composite structures such as The Complaints Book. The newspaper genre of advertisements often used by the young Chekhov can also be reinterpreted as a composite structure of the series or the list type. In the creative laboratory of Chekhov, this element of interdiscourse is transformed into an artistic technique: the metonymic logic of the list becomes an index of the moral state and atmosphere of the depicted reality.
