Evaluation of the effect of prostate diameters on erectile dysfunction in patients who underwent low-anterior resection

OBJECTIVE

Male erectile dysfunction is an important complication of rectal surgery. In this research, the effect of prostate dimensions on the development of postoperative erectile dysfunction in patients diagnosed with mid-rectum adenocarcinoma who underwent low anterior resection (LAR) is examined.

PATIENTS AND METHODS

Thirty-one male patients diagnosed as mid-rectal adenocancer were included. The International Index of Erectile Function (IIEF) questionnaire was used to determine the patients' pre and postoperative erectile dysfunction levels, and the level of relationship between the change in these IIEF scores and prostate measurements determined by computed tomography were evaluated.

RESULTS

There were statistically significant differences between IIEF index score and anterior posterior (AP) and transverse (TR) measurements (p≤0.001; p≤0.001), but no statistically significant difference was found between craniocaudal (CC) measurement values (p=0.169).

CONCLUSIONS

The risk of nerve injury will be higher in those with a small prostate transverse diameter. Intraoperative nerve monitoring should be recommended primarily in younger patient groups.

The wound area as a parameter guiding the timing of abdominal closure in the management of patients undergoing open abdominal procedures

OBJECTIVE

Surgical site infections (SSI) are incomparably troublesome and complicated, and some of them require an open abdomen (OA) procedure. While deciding the timing of abdominal closure, wound area calculation method and laboratory parameters can be used to guide the timing of abdominal closure after OA procedures.

PATIENTS AND METHODS

The records of the patients who had undergone open abdomen during their treatment course and were followed up with vacuum-assisted closure (VAC) technique between December 2015 and December 2019 were retrospectively analyzed. The laboratory results before the first VAC application and the results after the VAC change were compared to determine a predictive parameter. The ImageJ program was used in five patients to compare the size of the wounds at the time of the decision to close them and before the first VAC application.

RESULTS

102 patients were analyzed. The ratio of the last wound area to the wound area at the time of the first VAC application in five patients was 0.30, 0.41, 0.34, 0.27, 0.46 (mean: 0.36, standard deviation: 0.078) which were measured and calculated by ImageJ software.

CONCLUSIONS

We think that the concept of wound reduction ratio, which was calculated by a computer program, can be used as a concrete equivalent of the wound closure eligibility criteria decided by clinical experience.

The effects of bee venom on liver and skeletal muscle in exhaustive swimming rats

Oxidative damage and proinflammatory cytokines are involved in exhaustive exercise-induced fatigue. This study aimed to investigate the effects of bee venom, a natural toxin, on fatigue and tissue damage in rats that underwent forced swimming exercise. Rats were divided into four groups: control, swimming exercise (SE), bee venom (BV) and swimming exercise + bee venom (SE + BV). SE and SE + BV groups were subjected to forced swimming (load of 7% body weight) for 5 days. BV and SE + BV groups were injected with 1 mg/kg BV subcutaneously. Swimming time, blood lactate and TNF-α levels, MDA and GSH levels in liver and gastrocnemius muscle were evaluated. Swimming time was shorter in SE + BV group than SE group. There was no difference in lactate levels between SE and SE + BV groups. MDA and GSH levels were increased in SE, BV and SE + BV groups. TNF-α levels were increased in BV group compared to control and SE groups. Our study demonstrated that BV administration before exhaustive exercise in rats did not provide anti-fatigue effect. Additionally, BV did not show anti-inflammatory activity and had different effects on antioxidant capacity at tissue level. Further research might explore the effects of different doses and durations of BV on exhaustive exercise.

Assessment of Palliative Care in Lung Cancer in Turkey

OBJECTIVE

To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms.

SUBJECTS AND METHODS

This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ2, Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis.

RESULTS

The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled.

CONCLUSION

In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey.

Comparison of thiol/disulphide homeostasis parameters in patients with COPD, asthma and ACOS

OBJECTIVE

Chronic obstructive pulmonary disease (COPD), asthma and asthma-COPD overlap syndrome (ACOS) are obstructive pulmonary disorders with different manifestations. Status of oxidation in tissues is important in obstructive pulmonary disorders. Smoking, acute exacerbations of COPD and asthma were associated with a marked imbalance in oxidant or antioxidant status due to increased oxidative stress in tissues and blood. Oxidative conditions may cause a reversible formation of mixed disulphides among protein thiol groups. The aim of this study was to compare parameters related with thiol/disulphide homeostasis in patients with COPD, asthma and ACOS.

PATIENTS AND METHODS

Patients (n= 135, 69 females, 66 males) who were referred with a diagnosis of COPD, asthma or ACOS were included in the study. Thiol/ disulphide homeostasis parameters in blood were analysed by a newly established method that measures the exact thiol/ disulphide status in the body.

RESULTS

The patients with COPD, asthma or ACOS were similar for demographic parameters other than age and number of cigarettes smoked. Measured thiol/disulphide homeostasis parameters were similar among these patient groups. When these biochemical measurements were adjusted for age and number of cigarettes by using regression analysis, similarity for thiol/disulphide homeostasis parameters among patient groups persisted.

CONCLUSIONS

To best of our knowledge, this is the first study to compare thiol/disulphide homeostasis parameters in COPD, asthma and ACOS patients. Similarity of thiol/disulphide homeostasis parameters among these patient groups supports the current view of Dutch hypothesis that COPD, asthma and ACOS share similar pathophysiological features but display different clinical manifestations.
