Randomized Controlled Trial
BACKGROUND
The ceramic soft tissue trimming bur (CeraTip™) was initially introduced for use in gingivoplasty but has recently been used for gingival depigmentation. The aim of this study is to compare the efficacy of depigmentation between the novel CeraTip™ and the gold-standard surgical scalpel technique.
METHODS
Eight healthy, nonsmokers with moderate to severe gingival hyperpigmentation in both arches were randomly assigned for CeraTip™ depigmentation in one arch as the test group (TG) and scalpel depigmentation in the opposite arch as the control group (CG). Pigmentation indices were used to assess clinical performance. Treatment time, pain level, and esthetic satisfaction were the parameters of patient experience. The assessments were performed at baseline, one week, one month, and three months.
RESULTS
At all assessment visits, pigmentation intensity represented by the Dummet oral pigmentation index (DOPI), and pigmentation distribution represented by the Hedin melanin index (MI), were significantly lower than those at baseline (p < 0.001) in both groups. When comparing the two groups, Scalpel depigmentation had better initial clinical outcomes, while CeraTip™ had less visible repigmentation, pain scores, treatment time, and greater esthetic satisfaction. However, none of the differences were statistically significant.
CONCLUSION
Both techniques successfully removed gingival hyperpigmentation with comparable clinical performance. The patients preferred CeraTip™ depigmentation.

INTRODUCTION
Needlestick injuries (NSIs) represent a significant occupational health risk in healthcare settings. These injuries, caused by contaminated sharps such as needles, vials, and scalpel blades, can lead to percutaneous exposure to infectious materials. Despite the severity of NSIs, they often go unreported, highlighting a critical gap in occupational safety protocols.
AIMS
This study aimed to investigate the occurrence of NSIs among healthcare workers (HCWs) by sex, profession, and working areas. It also sought to explore the underlying reasons for these injuries and the factors contributing to their underreporting.
METHODOLOGY
Adhering to the RECORD guidelines (Reporting of studies Conducted using Observational Routinely Collected Data), this record-based study involved a retrospective analysis of reported NSIs. Data were collected from voluntary reports by HCWs who experienced NSIs or exposure to potentially infectious materials such as blood and body fluids. Statistical analysis was conducted using IBM SPSS Statistics for Windows, Version 16 (Released 2007; IBM Corp., Armonk, New York) and Microsoft Excel 2010 (Microsoft Corporation, Redmond, Washington).
RESULTS
Data from 142 participants indicated a higher proportion of females experiencing NSIs compared to males, with rates of 57.7% pre-COVID and 60.6% during COVID. There were notable shifts in NSI rates across professions, with increases observed among staff nurses and ward attendants/helpers. Analysis of injury circumstances revealed a decrease in sampling procedure-related injuries but an increase during intravenous procedures and biomedical waste segregation. Injuries occurring on the right-hand index finger decreased from 52.1% pre-COVID to 31% during COVID, while those on the left-hand index finger increased from 19.7% pre-COVID to 39.4% during COVID. Statistically significant associations were found between the injury site and the place of occurrence (p=0.021). Healthcare professionals commonly cleansed the site with disinfectants and used personal protective equipment (PPE) kits, with increased PPE usage noted during the COVID-19 pandemic. These findings emphasize the evolving dynamics of NSIs among HCWs and underscore the importance of tailored preventive measures during pandemics.

Ankyloglossia, also known as tongue-tie, is a rare congenital anomaly of the oral cavity that not only causes difficulties in breastfeeding and teeth cleaning but also causes difficulty in speech articulation. Our patient faced difficulty in freely moving his tongue because of the short lingual frenulum wherein laser lingual frenectomy was indicated. The patient was treated successfully with a soft tissue diode laser having a wavelength of 445 nanometers. The use of a low-wavelength diode laser becomes relatively complimentary to standard scalpel surgery because of patient consolation, offers a blood-free area, reduces inflammation and edema, and is less damaging to thermal tissues.

Background Gingival pigmentation (GP), characterized by the presence of melanin in the gingival tissues, is a common aesthetic concern in dental practice. While it poses no inherent health risks, the visible discoloration may cause psychological distress for individuals seeking optimal dental aesthetics. Understanding the efficacy of various methods is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival depigmentation (GD). Aim The objective of the study was to compare the effectiveness of scalpel and microneedling (MN) with ascorbic acid in the treatment of GD. Materials and methods Sixteen patients who had a complaint of GP were included in the study, of whom eight were allocated for depigmentation with a scalpel, and the other eight patients were treated with the MN technique with ascorbic acid. Postoperative wound healing scores were evaluated on the first and seventh days, respectively. The intensity of depigmentation was assessed at baseline, in the first month, and at the end of the third month, respectively. Results The mean Dummett-Gupta Oral Pigmentation Index (DOPI) score at baseline was 2.65±0.16 and 2.61±0.17 in the surgical and microneedling groups with ascorbic acid, respectively. The mean DOPI score at the end of the third month was 1.67±0.39 and 0.87±0.17 in the scalpel and MN with ascorbic acid groups, respectively. There was a statistically significant difference between the scalpel and MN with ascorbic acid groups at the end of the first and third months, respectively, where MN with ascorbic acid showed aesthetically pleasing outcomes. Patients treated with the scalpel technique showed incomplete healing and ulceration on the first and seventh days after the procedure when compared to the MN technique with ascorbic acid. The healing index scores were statistically significant in the MN with ascorbic acid group. Conclusion The MN technique with ascorbic acid is a successful technique for treating GD. It showed aesthetically gratifying outcomes when compared to the conventional surgical technique.

In recent research, the expansion in the use of Mg alloys for biomedical applications has been approached by modifying their surfaces in conjunction with micro-arc oxidation (MAO) techniques which enhance their abrasion and corrosion resistance. In this study, combining laser texturing and MAO techniques to produce the dense ceramic coatings with microstructures. On the surface of the AZ31 Mg alloy, a micro-raised annulus array texture has been designed in order to increase the surface friction under liquid lubrication and to improve the operator's grip when holding the tool. For this work, the micro-morphology of the coatings was characterised, and the friction properties of the commonly used scalpel shank material 316 L, the untextured surface and the textured surface were comparatively analysed against disposable surgical gloves. The results show that the Laser-MAO ceramic coating grows homogenous, the porosity decreases from 14.3% to 7.8%, and the morphology after friction indicates that the coating has good wear resistance. More specifically, the average coefficient of friction (COF) of the three types of gloves coated with Laser-MAO ceramic was higher than that of the 316 L and MAO ceramic coatings under the action of the annulus-integrated texture under the lubrication conditions of physiological saline and defatted sheep blood, which achieved the goal of increasing friction for the purpose of helping to prevent the problem of tool slippage from the hand.

Comparative Study
A papilloma is a benign tumor arising from an epithelial surface. Mostly a papilloma appears as an asymptomatic intraoral lesion and is often associated with the human papilloma virus (HPV). In this case report two similar, verrucous papules, sessile bilateral on the back of the tongue, were surgically removed in a 65-year-old male patient. Thereby two different methods of treatment were compared. On the right side of the back of the tongue, excision by scalpel, as the gold standard treatment modality, was performed. On the left side a surgical removal by a CO2 laser was performed. In a photothermal procedure, without direct contact to the tissue, the laser beam is cutting through the mucosa. Secondary wound healing can take place. Both methods were compared in relation to their application, wound healing, quality of the biopsy and morbidity. Postoperative less discomfort and a slightly faster wound healing could be seen after scalpel removal. The histopathological examination was comparable for both methods.

Pyogenic granuloma (PG) refers to an acquired benign proliferation most commonly seen within the oral cavity involving lips, palate, and gingiva. The term is misleading since it is a type of lobular capillary haemangioma but not an infection. It frequently recurs but lacks the capacity for malignant alteration. Depending on where the PG is located, one may experience discomfort or irritation. PGs often lead to differential diagnoses by clinicians, which include capillary hemangioma, neurofibroma, melanoma, and hyperplasia. Therefore, one must confirm a PG by diagnosing and analysing it by clinical and histopathological examinations, and treatment options should be formulated according to the evaluation. Sometimes, a biopsy of the lesion can be taken for final diagnosis. Various treatment approaches are available, including conventional scalpel excision, laser, electrocautery, and cryotherapy. Surgical excision is preferable due to the likelihood of malignancy, as it provides the best cosmetic appearance and produces a specimen for pathologic assessment. After confirming all the clinical evaluatory parameters and routine haematological examinations, which proved satisfactory and within normal ranges, this case of a 45-year-old female with soft tissue growth of the gingival origin was managed by electrocautery, and the PG was confirmed by a clinical-histopathological examination.

INTRODUCTION
Ankylosing spondylitis is a spondyloarthropathy that commonly involves the axial skeleton with predilection to the sacro-iliac joints and spine. The disease frequently results in a smooth globular kyphotic deformity of the spine; however, a coronal plane scoliotic deformity is extremely rare. We present a unique case of scoliotic deformity in a patient diagnosed with ankylosing spondylitis. To the best of our knowledge, following a review of the literature, this appears to be the first report of this kind.
CASE REPORT
A 23-year-old male patient presented with chronic back pain, stiffness, and a truncal shift of the body. He had a rigid left-sided thoracolumbar curve measuring 41° with a coronal imbalance of 3.6 cm. We present a case report on scoliosis deformity correction performed with a four-level asymmetric pontes osteotomy using a bone scalpel with excellent correction of the scoliotic deformity that was well maintained at 2-year follow-up.
CONCLUSION
Scoliosis in ankylosing spondylitis has not been documented in literature. We report the complete correction of the deformity, which is well maintained at the 2-year follow-up.

Recent research studies reported that the employment of wearable augmented reality (AR) systems such as head-mounted displays for the in situ visualisation of ultrasound (US) images can improve the outcomes of US-guided biopsies through reduced procedure completion times and improved accuracy. Here, the authors continue in the direction of recent developments and present the first AR system for guiding an in-depth tumour enucleation procedure under US guidance. The system features an innovative visualisation modality with cutting trajectories that 'sink' into the tissue according to the depth reached by the electric scalpel, tracked in real-time, and a virtual-to-virtual alignment between the scalpel's tip and the trajectory. The system has high accuracy in estimating the scalpel's tip position (mean depth error of 0.4 mm and mean radial error of 1.34 mm). Furthermore, we demonstrated with a preliminary user study that our system allowed us to successfully guide an in-depth tumour enucleation procedure (i.e. preserving the safety margin around the lesion).

Cavitron ultrasonic surgical aspirator (CUSA) compared with conventional pancreatic transection in distal pancreatectomy: study protocol for the randomised controlled CUSA-1 pilot trial.
BACKGROUND
Postoperative pancreatic fistula (POPF) remains the most common and serious complication after distal pancreatectomy. Many attempts at lowering fistula rates have led to unrewarding insignificant results as still up to 30% of the patients suffer from clinically relevant POPF. Therefore, the development of new innovative methods and procedures is still a cornerstone of current surgical research.The cavitron ultrasonic surgical aspirator (CUSA) device is a well-known ultrasound-based parenchyma transection method, often used in liver and neurosurgery which has not yet been thoroughly investigated in pancreatic surgery, but the first results seem very promising.
METHODS
The CUSA-1 trial is a randomised controlled pilot trial with two parallel study groups. This single-centre trial is assessor and patient blinded. A total of 60 patients with an indication for open distal pancreatectomy will be intraoperatively randomised after informed consent. The patients will be randomly assigned to either the control group with conventional pancreas transection (scalpel or stapler) or the experimental group, with transection using the CUSA device. The primary safety endpoint of this trial will be postoperative complications ≥grade 3 according to the Clavien-Dindo classification. The primary endpoint to investigate the effect will be the rate of POPF within 30 days postoperatively according to the ISGPS definition. Further perioperative outcomes, including postpancreatectomy haemorrhage, length of hospital stay and mortality will be analysed as secondary endpoints.
DISCUSSION
Based on the available literature, CUSA may have a beneficial effect on POPF occurrence after distal pancreatectomy. The rationale of the CUSA-1 pilot trial is to investigate the safety and feasibility of the CUSA device in elective open distal pancreatectomy compared with conventional dissection methods and gather the first data on the effect on POPF occurrence. This data will lay the groundwork for a future confirmatory multicentre randomised controlled trial.
ETHICS AND DISSEMINATION
The CUSA-1 trial protocol was approved by the ethics committee of the University of Heidelberg (No. S-098/2022). Results will be published in an international peer-reviewed journal and summaries will be provided in lay language to study participants and their relatives.
