Does Texting While Walking Affect Gait's Plantar Pressure Parameters?

BACKGROUND: This study aims to examine the possible effects of mobile phone use on plantar pressure and spatiotemporal parameters during walking. MATERIALS AND METHODS: Thirty volunteers (18 males and 12 females) participated in the study. A 10-m walking path was prepared, and a messaging connection was established. They were asked to write three posts without word or character mistakes and participants walked on the path walk as much as they wanted on the trail to make sure they were walking at their own pace. The gait's spatiotemporal parameters and plantar pressure parameters were recorded while walking. A paired samples t-test was used to determine whether there was a difference between normal walking and walking while texting. RESULTS: While walking and writing a message, cadence, speed, and step length decreased significantly (P < 0.05). In the plantar pressure parameters, the fore- and midfoot load and pressure were significantly increased (P < 0.05). CONCLUSIONS: Compared to normal walking, the forces on the forefoot and midfoot and the pressure per unit area increased in walking while texting. It is thought that the pace of walking slows down, and focus and attention shift to the front of the body.

Is laparoscopic surgery risk for surgical teams during the coronavirus disease pandemic? An in vitro study with a laser and high-speed camera.

OBJECTIVE: Laparoscopic surgery has been suggested to pose a risk of infection to the surgical team due to aerosol and gas leakage during the coronavirus (COVID-19) pandemic. However, there have been no studies on the risk of gas and aerosol leakage in laparoscopic surgery. We aimed to answer the question "Is the aerosol and gas leakage in laparoscopy is hazardous in terms of coronavirus infection?" with this study. MATERIALS AND METHODS: In this study, gas and aerosol leaks were documented by simulating the entry and exit maneuvers from a trocar during laparoscopic surgery using a high-speed camera, fog, and laser in a model representing the abdomen. RESULTS: The maximum gas and aerosol leakage were found during wet gauze extraction from the 10 mm trocar, and its velocity reached 7.5 m/s. The fastest aerosol leakage rate was observed when a 5 mm grasper was extracted from the 5 mm trocar. The results of the subsequent trials were consistent with these values. CONCLUSIONS: Higher leakage speeds were observed than the velocity of the exhaled air in a resting person. The surgical crew members, who work very close to the trocars and each other, are at serious risk of infection with COVID-19 which can spread as fast as exhalation speed through trocars. Since there is an evident risk of infection for the surgical crew from laparoscopic surgery of a patient whose intraabdominal fluids are infected with COVID-19, patients must be evaluated elaborately for COVID-19 preoperatively and infected patients should undergo surgery conventionally.

Comparison of incisional hernia models in rats: an experimental study.

PURPOSE: Incisional hernia repair is a frequently performed operation worldwide. In this experimental study, our aim is to present the incisional hernia model after creating midline laparotomy and several type of defects on abdominal wall of the rats. Thereby, the method determined here may be used in future experimental incisional hernia repair studies. METHODS: After approval, 32 male rats were randomly seperated into 4 groups of 8 animals each, and were operated to form an incisional hernia; Sham group, 5 cm incision group, 5 cm incision plus capitonnage group, and 5 cm incision plus 2 × 4 cm muscle excision group, respectively. On the 28th postoperative day after killing, the abdominal anterior wall of rats were removed for histopathological and biomechanic examination. RESULTS: The incisional hernia size was found to be statistically different in at least one group (p = 0.001). The incisional hernia size in Group 4 was found to be significantly higher than Group 2 (p = 0.001). When the tension and elongation values were examined, there was a difference in at least one group (p < 0.001 and p = 0.029, respectively). Histopathological examination shows that the degree of inflammation and fibrosis varies significantly (p = 0.001 and p = 0.002, respectively). CONCLUSION: This study has lead us to believe that the rat model created by applying muscle excision from the midline of the abdomen is the ideal incisional hernia model that can be used in future experimental incisional hernia studies.

Comparison of single-incision and conventional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis.

BACKGROUND: Clinical studies indicate that single-incision laparoscopic cholecystectomy (SILC) has many advantages over conventional laparoscopic cholecystectomy (CLC), such as improved cosmesis, reduced postoperative pain, and shorter hospital stay. The aim of this study was to compare quality of life, body image, and cosmesis between single-incision laparoscopic and conventional laparoscopic approaches in patients undergoing cholecystectomies. SUBJECTS AND METHODS: This retrospective study between SILC and CLC and was conducted among 58 patients undergoing SILC and CLC from January 2011 to March 2013 in Turkey. After the surgery, the EuroQol-5 Dimension Questionnaire (EQ-5D™), and body image questionnaire (BIQ) were administered to the patients. RESULTS: Differences between the early and late postoperative scores in the EQ-5D were statistically significant (P < 0.001). Differences between most BIQ areas favored SILC, especially regarding cosmesis (P = 0.016); SILC patients had higher satisfaction with their scar's appearance. CONCLUSION: SILC is a promising alternative to traditional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis in selected patients.

Combat application tourniquet (CAT) eradicates popliteal pulses effectively by correcting the windlass turn degrees: a trial on 145 participants.

INTRODUCTION: We aimed to define an ideal range of windlass turn degrees for 100 % success rates within the study population. METHODS: CAT was applied at mid-thigh level. Data included age, lower extremity circumference (LEC), body mass index (BMI), and mean arterial pressure (MAP). Windlass turn degrees were measured in failed and successful participants. The failed participants' windlass mechanisms were twisted until the popliteal artery was occluded. Failure to success and additional turn degrees to secure the windlass mechanism of CAT was determined. Doppler ultrasound was used to examine the popliteal artery blood flow. RESULTS: 145 servicemen have participated in the study. Initially, 70 % successfully applied CAT. There was no statistically significant difference in BMI and MAP values between successful and failed participants. The mean LEC for failed and successful applications were 57.5 ± 4 and 56.8 ± 4, respectively. The required turn degrees for success ranged between 45° and 270°. After correction, the cumulative success rate of 93 and 100 % was reached at 990° and 1170° overall turn degrees. DISCUSSION: In order to adequately stop limb hemorrhage, soldiers should be taught their optimal turn degrees.

Role 2 military hospitals: results of a new trauma care concept on 170 casualties.

INTRODUCTION: In recent military conflicts, military surgeons encounter more high-energy injuries associated with explosives. Advances in the field care and shorter evacuation time increased survival. However, casualties still incur severe injuries especially to the extremities. We present wound patterns, anatomical distribution and severity of injuries in a Role 2 hospital. MATERIALS AND METHODS: Two years data have been retrospectively reviewed. Only explosives and firearms injuries were included in the study. Patient profile, admission details, mechanism of injury, AIS anatomical locations, ISS, surgical and medical treatments have been analyzed. RESULTS: Data revealed 170 male casualties. IEDs and GSW accounted for 133 (78%) and 37 (22%) casualties, respectively. An average of 1.8 IED and 1.2 GSW anatomical locations were exposed to injuries. Regardless of the mechanism, injuries were most commonly located in the extremities. IEDs caused significantly higher soft tissue injuries. DISCUSSION: Explosives do not necessarily cause more severe injuries than firearms. However, fragments create multiple, complicated soft tissue injuries which constitute more than half of the injuries. Timely wound debridement and excision of contaminated tissue are crucial to manage extremity soft tissue injuries. CONCLUSION: Casualty care should be assessed within the context of the capabilities present at a hospital and the cause, type and severity of the wounds. The NATO description of Role 2 care only requires an integrated surgical team for damage control surgery with limited diagnostic and infrastructural capabilities.

An evaluation of combat application tourniquets on training military personnel: changes in application times and success rates in three successive phases.

INTRODUCTION: Haemorrhage from the injured extremity is a significant cause of preventable death in military settings. This study evaluated the effect of training on the efficacy of the combat application tourniquet (CAT) and to define standards for military personnel. METHOD: Participants from a training tank battalion were randomised. Data collected included age, body mass index, mean arterial pressure, hand dominance, femoral artery diameter and skin thickness. The study involved tourniquet application times (AT) and application success rates in basic, after-training and eyes-closed phases. Doppler ultrasound was used to identify the presence or absence of popliteal, radial and ulnar artery pulses. RESULTS: A total of 102 trainees participated. In the after-training phase, the left and right upper extremity ATs were 35 ± 13.1 s, and 34.8 ± 13.5 s and the right and left lower extremity ATs were 20.6 ± 6.0 s and 20.5 ± 5.5 s, respectively. The overall tourniquet success rates in three successive study phases were 69.6%, 82.4% and 91.2%, respectively. A negative significant relationship was found between extremity circumference and tourniquet success. DISCUSSION: The results show that the efficacy of CAT application increases with training. Further studies are required to investigate the reasons underlying application failures. This single group prospective randomised study involves level of evidence 4.

Natural behaviour and surgical treatment of appendiceal carcinoids: an analysis of 2,376 consecutive emergency appendectomies.

OBJECTIVE: Carcinoid tumor of appendix is a rare condition. Its rarity may give rise to variances in its management. We aimed to demonstrate the occurrence and form of presentation of carcinoid tumor of appendix, as well as variations in its treatment. METHODS: All appendicectomies that took place between 2000 and 2008 were considered for study. RESULTS: A total of 2,376 appendicectomies were performed during this period while carcinoid tumours were diagnosed in 27 patients (1.13%). The mean age of patients with carcinoid tumor (26.7 years) was almost the same as that of patients with non-carcinoid pathology (28.1 years). The incidence of male patients was higher than that of females amongst the carcinoid tumor group (female/male ratio: 1/4). None of the carcinoid tumors were identified at operation. One patient (3.7 %) required right hemicolectomy. This patient was followed-up in an inconsistent manner. CONCLUSIONS: Carcinoid tumour of the appendix remains an incidental diagnosis. Patients with carcinoid were significantly younger than those with non-carcinoid conditions in the study. Re-operation rate was low. The interval to definitive surgery was very short and only one patient was followed up. No consideration as to whether the surgery was complete or not was done in the study (Tab. 1, Fig. 1, Ref. 29).

A rare complication after thyroidectomy: perforation of the oesophagus: a case report.

Perforation of the cervical oesophagus after thyroidectomy is an exceptionally rare complication. Total thyroidectomies, particularly for recurrent cases might possess an increased risk. Although rare, it has high mortality and morbidity. A patient that developed oesophagus perforation after a total thyroidectomy in a peripheral hospital for recurrent nodular goitre was treated and followed-up in our clinic. This well-documented case is discussed in conjunction with the information presented in the literature.
