Cerebral arteriovenous malformations : usability of Spetzler-Martin and Spetzler-Ponce scales in qualification to endovascular embolisation and neurosurgical procedure

Purpose: Arteriovenous malformations (AVMs) are connected with cerebral haemorrhage, seizures, increased intracranial pressure, headaches, mass effect, and ischaemia symptoms. Selection of the best treatment method or even deciding if intervention is required can be difficult. Material and methods: The study included 50 patients who were diagnosed with cerebral AVMs and treated in our Centre between 2008 and 2014. A total of 111 procedures were performed, including 94 endovascular embolisations and 17 neurosurgical procedures. Medical records and imaging data were reviewed for all patients. All AVMs were measured and assessed, allowing classification in Spetzler-Martin and Spetzler-Ponce scales. Results: Complete or partial treatment was observed in 88.24% of neurosurgical procedures and in 84.00% of embolisations. Early complication rate was 21.28% for embolisation and 17.65% for neurosurgical procedures, while Glasgow Outcome Scale was 4.89 (σ = 0.38) and 5.0 (σ = 0.00), respectively. According to the Spetzler-Martin scale, cerebral haemorrhages occurred more frequently in grade 1, but no statistical significance was observed. In Spetzler- Ponce class B lower grades in Glasgow Coma Scale (GCS) were noticed (p = 0.02). Lower GCS scores were also correlated with deep location of AVM and with eloquence of adjacent brain. Patients with Spetzler-Martin grade 1 were more frequently qualified for neurosurgical procedures than other patients. Conclusions: Treating AVMs requires coordination of a multidisciplinary team. Both endovascular embolisation and neurosurgical procedure should be considered as a part of multimodal, frequently multistage treatment. Spetzler-Martin and Spetzler-Ponce scales have an influence on haemorrhage frequency and patients’ clinical condition and should be taken into consideration in selecting the treatment method

The relationship between the result of FMS research and risk of sports injuries

Physical effort is undoubtedly linked to human functioning. Daily activities, professional work and locomotion are basic signs of physical exercises. Civilization development has caused many changes in the lives of the population and the main reason for these changes is sedentary life. Hypokinesis leads to the general weakening of the body. Professional athletes belong to the group of people who are not exposed to changes related to sedentary lifestyle. However, they are more exposed to the occurrence of musculoskeletal injuries which are called sports injuries. Despite conducting regular periodic examinations and screening among athletes, the problem of prevention and the occurrence of the injuries has not been appropriately described. The objectives of the study were to assess physical fitness of a selected group of athletes using the Functional Movement Screen, to examine the correlation and statistical significance between the FMS score and the number of past injuries and to determine the need for prevention of sports injuries for athletes. The study involved 25 handball players from the Pogoń Szczecin team in the years 2015 - 2017. The study consisted of two parts: author's questionnaire survey and FMS test. Statistical analysis of the results did not show any significant effect of FMS on the number of injuries in handball (r = -0,19). The main factor that affects the number of injuries is the long-term practice of players on handball courts (r = 0,54). Commonly known phenomenon among the players is participating in trainings despite damages and pain that results from the past injuries

Long-term antibiotic prophylaxis in urology and high incidence of "Clostridioides difficile" infections in surgical adult patients

Clostridioides difficile infections are the main cause of antibiotic-related diarrhea. Most of them come in the form of healthcare-associated Clostridioides difficile infections (HA-CDI). The aim of the study was to analyze HA-CDI epidemiology and the relationship between antibiotic consumption and CDI epidemiology at St Luke’s Provincial Hospital in Tarnow, Poland. In 2012–2018, surveillance of CDI was carried out in adult surgical wards at St Luke’s Provincial Hospital. The data were collected in accordance with the methodology of the Healthcare-Associated Infections Surveillance Network (HAI-Net), European Centre for Disease Prevention and Control (ECDC), and the ATC/DDD system (Anatomical Therapeutic Chemical Classification System) of the World Health Organization. In total, in the study period, 51 cases of CDI involved CA-CDI (24.5%) and 147 were HA-CDIs (75.5%). The most CA-CDIs were found in the general surgery (32.6%) and urology (17.0%) wards. CA-CDI incidence was 0.7/1000 patients and for HA-CDI it was 2/1000 patients (4.4/10,000 patientdays (pds)). The highest HA-CDI incidence was in the neurosurgical departments (18/10,000 pds) and oncological surgery (8.4/10,000) pds. There was a significant positive correlation between CA-CDI and HA-CDI (correlation of 0.943, p < 0.001) and between the number of patients hospitalized and HA-CDI (correlation of 0.865, p = 0.012). The total antibiotic consumption amounted to 0.7 DDD/10,000 pds; it was the highest in the urology ward (0.84/10,000 pds) and 49.5% of the antibiotics were fluoroquinolones (0.41/10,000 pds). On the basis of regression coefficients, a positive correlation was demonstrated between the use of fluoroquinolones and the HA-CDI incidence rate. Both a high percentage of CDI cases and a high intake of antibiotics were recorded in the urology department. About half of all antibiotics were fluoroquinolones

Enhanced recovery after colorectal surgery in elderly patients

INTRODUCTION: The elderly will soon constitute 20% of the population. Their number is constantly rising, particularly in developed countries. It was found that they particularly benefit from the use of minimally invasive surgery. The Enhanced Recovery After Surgery (ERAS) protocol may further improve clinical outcomes in this group of patients. AIM: To assess the implementation of the ERAS protocol in elderly patients submitted to laparoscopic colorectal surgery. MATERIAL AND METHODS: Ninety-two patients who underwent elective laparoscopic colorectal surgery were included in the study. Patients were divided into group 1 (≤ 65 years) and group 2 (> 65 years). Perioperative care was based on ERAS Society guidelines. Length of hospital stay, time of first stool passage, perioperative complications and readmissions were analyzed. RESULTS: Group 2 patients had higher ASA grades in comparison to group 1. In all cases, oral fluid intake started on the day of surgery. The groups did not differ according to oral fluid tolerance, first stool passage time or length of hospital stay. Number and character of perioperative complications were comparable between the two groups. Four patients were readmitted within 30 days after discharge. One patient required reoperation. CONCLUSIONS: Implementation of the ERAS protocol is possible regardless of the age of surgical patients. Its use in the elderly allows the length of hospitalization to be shortened and is not associated with higher risk of postoperative complications or readmissions

Adrenal Incidentalomas: Should We Operate on Small Tumors in the Era of Laparoscopy?

Tumor size smaller than 4 cm as an indication for surgical treatment of incidentaloma is still a subject of discussion. Our aim was the estimation of the incidence of malignancy and analysis of treatment outcomes in patients with incidentaloma smaller than 4 cm in comparison to bigger lesions. 132 patients who underwent laparoscopic adrenalectomy for nonsecreting tumors were divided into two groups: group 1 (55 pts., size < = 40 mm) and group 2 (77 pts., size > 40 mm). Operation parameters and histopathological results were analyzed. No differences in group characteristics, mean operation time, and estimated blood loss were noted. Complications in groups 1 and 2 occurred in 3.6% and 5.2% of patients, respectively (P=0.67). Malignancy in groups 1 and 2 was present in 1 and 6 patients, respectively (P=0.13). Potentially malignant lesions were identified in 4 patients in group 1 and 4 patients in group 2 (P=0.39). The results do not allow for straightforward recommendations for surgical treatment of smaller adrenal tumors. The safety of laparoscopy and minimal, but impossible to omit, risk of malignancy support decisions for surgery. On the other hand, the risk of malignancy in smaller adrenal tumors is lower than surgical complications, which provides an important argument against surgery

Watching DNA replication inhibitors in action: Exploiting time-lapse microfluidic microscopy as a tool for target-drug interaction studies in Mycobacterium .

Spreading resistance to antibiotics and the emergence of multidrug-resistant strains have become frequent in many bacterial species, including mycobacteria - a causative agents of severe diseases and have profound impacts on global health. Here, we used a system of microfluidics, fluorescence microscopy and target-tagged fluorescent reporter strains of Mycobacterium smegmatis to perform real-time monitoring of replisome and chromosome dynamics following the addition of replication-altering drugs (novobiocin, nalidixic acid and griselimycin) at the single-cell level. We found that novobiocin stalled replication forks and caused relaxation of the nucleoid, nalidixic acid triggered rapid replisome collapse and compaction of the nucleoid, while griselimycin caused replisome instability with subsequent over-initiation of chromosome replication and over-relaxation of the nucleoid. In addition to study target-drug interactions, our system also enabled to observe how the tested antibiotics affected the physiology of mycobacterial cells (i.e., growth, chromosome segregation, etc.)

Single-Incision Laparoscopic Cholecystectomy - can we Afford that? Cost Comparison of Different Surgical Techniques

One of the most commonly performed surgeries in general surgery wards with laparoscopic technique as a method of choice is gall-bladder excision. In addition to -the commonly used conventional laparoscopic cholecystectomy single incision laparoscopic cholecystectomy is getting more and more attention. Despite many works and studies comparing these methods, there is still a shortage of results assessing efficiency of this new surgical technique. The aim of the study was to evaluate cost-effectiveness of this method in Polish financial reality. We have analyzed costs of three different surgical techniques: conventional (multi- incision) laparoscopic cholecystectomy, SILC and ‘no -port’ SILC. Material and methods. We conducted a retrospective study that compared three groups of patients who underwent treatment with conventional laparoscopic cholecystectomy (n=20), SILC (n=20) and no-port SILC (n=20). These groups were matched by age, sex and BMI. Following parameters were analyzed: complication rate, operative time, operative costs, length of hospital stay, hospitalization costs. The SILC cases were performed with one of the three-trocar SILC ports available on the market. The ‘no- port’ SILC cases were performed by single skin incision in the umbilicus, insertion of one 10 mm trocar for the operating instrument, another instrument and scope were inserted directly thorough small incisions in the aponeurosis without a dedicated port Results. The average operative cost was significantly higher in the SILC group comparing to the conventional laparoscopy group and the no-port SILC group. There was no significant difference in complication rate, operative time, length of hospital stay, or hospitalization costs between the three groups Conclusions. Currently the cost of the dedicated SILC port does not allow a regular use of this procedure in Polish financial reality. According to our experience improved cosmesis is the only advantage of the single incision laparoscopy, therefore we believe that it is reasonable to consider this technique in a a very selected group of patients
