The COVID-19 pandemic has been reshaping the world by accelerating non-contact services and technologies in various domains. Hospitals as a healthcare system lie at the center of the dramatic change because of their fundamental roles: medical diagnosis and treatments. Leading experts in health, science, and technologies have predicted that robotics and artificial intelligence (AI) can drive such a hospital transformation. Accordingly, several government-led projects have been developed and started toward smarter hospitals, where robots and AI replace or support healthcare personnel, particularly in the diagnosis and non-surgical treatment procedures. This article inspects the remaining element of healthcare services, i.e., surgical treatment, focusing on evaluating whether or not currently available laparoscopic surgical robotic systems are sufficiently preparing for the era of post-COVID-19 when contactless is the new normal. Challenges and future directions towards an effective, fully non-contact surgery are identified and summarized, including remote surgery assistance, domain-expansion of robotic surgery, and seamless integration with smart operating rooms, followed by emphasis on robot tranining for surgical staff.

The most effective treatment methods for a herniated lumbar disc remain questionable. This report follows the patients course, from the onset of pain through the completion of the non-surgical treatment, and shows that a lumbar herniated disc, with radiculopathy, can be successfully treated with a non-surgical approach. This report discusses the possible explanations for disc resorption: retraction into the intervertebral space, dehydration/shrinkage and resorption due to an inflammatory reaction. A non-surgical approach can be an effective treatment option for a herniated lumbar disc.

Purpose: The purpose of this study was to determine the asymmetrical difference between the use of leg muscles on the surgical and non-surgical sides during initial lower extremity ergometer exercise after unilateral knee arthroplasty. Methods: Twelve elderly patients diagnosed with degenerative arthritis of the knee and who underwent unilateral arthroplasty were included in this study. The leg length of each subject was taken into account when setting the application distance of the lower extremity ergometer. The same pedal resistance, strength, and speed were used for all the subjects. The total angle of use of the ergometer (360°) was analyzed by dividing it into an extension section and a flexion section. Using a surface electromyography system, the activities of the muscles of the surgical and non-surgical sides were converted into maximal voluntary isometric contraction (MVIC) and analyzed using the paired t-test. Results: When the activities of the muscles on the surgical and non-surgical sides were compared, it was found that the rectus femoris and biceps femoris had significant differences in the flexion and extension sections (p < .05), and that the tibialis anterior significantly differed in the flexion section (p < .05). There was no significant difference in the extension section of the tibialis anterior muscle, or in the flexion and extension sections of the gastrocnemius (p >.05). Conclusion: The results of this study confirm that the rectus femoris, tibialis anterior, biceps femoris, and gastrocnemius on the surgical side act in an opposite manner to those on the non-surgical side during pedaling in the same section.

Purpose: The purpose of this study was to evaluate the improvement of periodontal health of generalized aggressive periodontitis (GAgP) diagnosed patients treated with non-surgical periodontal therapy accompanying systemic antibiotics administration. Methods: Two patients with GAgP were chosen for this study. Clinical indices were taken and a radiographic examination was performed at the baseline of the study and they were treated by periodontal therapy accompanying systemic antibiotics administration. Post-surgical visits were scheduled at regular intervals to check clinical and radiographic changes. Results: Through non-surgical periodontal therapy accompanying systemic antibiotics administration, GAgP patients showed decreased probing pocket depth, sulcus bleeding index, and increased attachment level and clinical index when comparing the initial and six month follow up data. In the six month follow-up radiographic examination after non-surgical periodontal therapy, resolution of the bony defect was observed. Conclusions: Non-surgical therapy combined with systemic antibiotics administration in GAgP patients is suggested to be an effective approach to enhance the periodontal health.

Purpose: Guide-wire localization (GWL) has been a standard technique for many years. Excision of nonpalpable malignant breast lesions with clear surgical margins reduces the risk of undergoing re-excision. The objective of the present study was to evaluate the efficacy of GWL biopsy for assessing surgical margins. Methods: This retrospective study concerned 53 patients who underwent GWL biopsy for non-palpable breast lesions and breast carcinoma diagnosed by histological examination. Age of the patients, tumour size, radiographic findings, breast density specifications, specimen volumes, menopausal status and family history of the patients and surgical margin status were recorded. Results: Median age was 53.3 years, median tumour size was 1.5 cm and median specimen volume was $71.5cm^3$. In fifteen patients (28%) DCIS and in 38 patients (72%) invasive ductal carcinoma was diagnosed. There was positive surgical margins in twenty eight (52.8%) patients. The median distance to the nearest surgical margin was 7.2 mm in clear surgical margins. Younger age and denser breast specifications were found as statistically significant factors for surgical margin status. Median age of the patients who had positive margins was 49.4 years where it was 56.9 years in the patients with negative margins (p=0.04). 79% of the patients with positive margins had type 3-4 pattern breast density according to BIRADS classification as compared to 48% in the patients who had negative margins (p=0.03). Some 38 patients who had positive or close surgical margins received re-excision (72%). Conclusion: Positive margin rates may be higher because of inherent biological differences and diffuse growth patterns in younger patients. There are also technical difficulties that are relevant to denser fibroglandular tissue in placing hooked wire. High re-excision rates must be taken into consideration while performing GWL biopsy in non-palpable breast lesions.

This study aims to investigate the clinical outcome following treatment of peri-implantitis lesions. Five subjects with 7 implants were treated with surgical approach. Four subjects with 6 implants were initially treated with non-surgical approach or hygiene control. However, inflammation was not resolved and more bone loss was found. Therefore, surgical treatment was performed. After surgical exposure of the defect, granulation tissue was removed and implant surface was treated using tetracycline and chlorhexidine. Then, the flaps were sutured. The wound healing was performed in a non-submerged mode. The present finding demonstrates stable results without progression of bone loss. In one subject, deep V shaped bone defect was filled with bone substitute (ICB, CanCellous Bone, Rockey Mountain Tissue Bank, USA), and resorbable membrane (Lyoplant$^{(R)}$, B.Braun Aesculap AG, Germany) was placed over the grafted defect and healing abutment was connected. However, the inflammation was not resolved and more bone loss was found. At one month after regenerative surgery, the implant was removed.

The purpose of this study was to examine the effect of smoking on the clinical, radiographic outcome of surgical peridontal therapy. The outcome of periodontal surgery was evaluated in 51 systemically healthy subjects that had received maintenance care. The study subject consisted of 26 smokers and 25 non-smokers. The average age of smoking patients was 51 years old and non-smoking patients was 48 years old. Changes of probing pocket depth(PPD) and radiographic bone height, and number of missing teeth compared between smokers and non-smokers during maintenance period after surgical therapy. The clinical parameters were less favorable in the smoking group compared with non-smoking group. The number and percentage of missing teeth were greater in smokers(21.6%) than non-smokers(l2.4%), especially in molars. The mean presurgery PPD was similar in smokers and non-smokers, molars and premolars, but significantly decreased at least 2 years after surgery. The mean PPD reduction was significantly greater in non-smokers than smokers. Both in the smoking and non-smoking group, the mean PPD reduction was significantly greater in premolars than molars. The radiographical evaluation was also less favorable in the smoking group than non-smoking group. The radiographic evaluation of bone height in smokers showed bone loss. On the contrary, bone height of non-smokers showed bone gain during the period of maintenance. But there was no significant difference between molars and premolars. The clinical and radiographic outcomes of the smoking group was less favorable than those of the non-smoking group. Therefore , smoking seems to influence on the clinical and radiographic outcomes of surgical periodontal therapy.

In order to determine the factors affecting the length of stay by pay status, a total of 961 in-patients medical records with appendectomy. cholecystectomy and Cesarean section discharged from the January 1979 to December 1981 from the University hospital were reviewed. Average length of stay showed no statistically significant difference by year between the insured and the non-insured patients, however multiple diagnoses and surgical complication were significantly different from single diagnosis and non-complicated cases. Surgical complication explained the length of stay mostly, and physician in discharge, multiple diagnoses, and accommodation in order for insured patients. Surgical complication, admission route, physician in charge and age in order explained the length of stay for non-insured patients.
