Evaluating the Clinical Efficacy of Maxillary Labial Frenectomy Procedure Using Diode Laser (980 nm) and Conventional Scalpel: An Observational Study

Aim

This is an era of minimally invasive and least traumatic surgical interventions being focused on. The traditional scalpel frenectomy technique offers an increase in post-operative sequelae. To unravel this scenario a comparative evaluation is carried out to find out the clinical outcomes and quality of life after maxillary labial frenectomy using a conventional scalpel and diode laser frenectomy of 980 nm.

Materials and Methods

Thirty-six subjects age ranging between 18 and 45 years reported to the Department of Oral and Maxillofacial Surgery, MES Dental College, Perinthalmanna with an aberrant frenal attachment of maxillary labial frenum were randomly assigned into two groups. Group A underwent the conventional scalpel technique and group B for the diode laser-assisted (980 nm) frenectomy technique. The post-operative parameters of ooze from the surgical site, pain, wound healing, and discomfort or acceptance of the procedure were assessed on day 1, day 7, and day 14, respectively.

Results

The diode laser group exhibited statistically significant clinical and healing outcomes. Less pain, minimal or absent ooze, increased healing, and better acceptance of the procedure with diode laser at 1, 7, and 14 days recall visit.

Conclusion

Surgical interventions involving needle puncture and the associated post-operative sequelae are the most dreaded experiences that make patients indifferent toward surgical treatments. Thus in terms of better clinical outcomes and improved quality of life diode laser frenectomy is an excellent alternative wherein a needleless anesthetic success followed by minimal surgical intervention and less post-operative sequelae with fast recovery is possible.

The Usefulness of a Simplified Navigation-Based Instrumentation for a Novice Surgeon in Primary Total Knee Arthroplasty: A Retrospective Analysis of a Randomized Controlled Trial

Background

A novel simplified navigation-based instrumentation system has been developed. It simplifies the existing navigation system and facilitates convenient bone cutting by positioning the tracker on an existing cutting block without additional pin fixation. This study aimed to compare the outcomes of this newly developed simplified navigation-based instrumentation system in primary total knee arthroplasty (TKA) performed by a novice surgeon with those of conventional surgical techniques.

Methods

From January 2020 to July 2020, 67 knees that underwent primary TKA using the ExactechGPS TKA Plus (group A) were compared to 68 knees that underwent primary TKA using a conventional technique (group B). All patients had a minimum follow-up of 24 months. The operative details such as tourniquet time were investigated. Postoperative hip-knee-ankle (HKA) angle and component position angles in the coronal and sagittal planes (α, β, γ, and δ angles) were evaluated. The outlier rates were compared between the groups as those lying outside ± 3°. Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, the Western Ontario and McMaster Universities Osteoarthritis Index for pain and function, and range of motion were compared.

Results

There was no statistically significant difference in average tourniquet time between the groups (74.3 vs. 70.3 minutes, p = 0.061). Outlier rates for HKA angle (7.5% vs. 23.5%, p = 0.010) and β angle (1.5% vs. 22.1%, p < 0.001) in group A were significantly lower than those in group B. There were no significant differences in clinical outcomes between the groups.

Conclusions

Primary TKA performed by a novice surgeon using a simplified navigation-based instrumentation system did not significantly increase the operation time, and more accurate lower extremity mechanical alignment and tibial component alignment in the coronal plane could be obtained.

Conventional and advanced detection techniques of foodborne pathogens: A comprehensive review

Foodborne pathogens are a major public health concern and have a significant economic impact globally. From harvesting to consumption stages, food is generally contaminated by viruses, parasites, and bacteria, which causes foodborne diseases such as hemorrhagic colitis, hemolytic uremic syndrome (HUS), typhoid, acute, gastroenteritis, diarrhea, and thrombotic thrombocytopenic purpura (TTP). Hence, early detection of foodborne pathogenic microbes is essential to ensure a safe food supply and to prevent foodborne diseases. The identification of foodborne pathogens is associated with conventional (e.g., culture-based, biochemical test-based, immunological-based, and nucleic acid-based methods) and advances (e.g., hybridization-based, array-based, spectroscopy-based, and biosensor-based process) techniques. For industrial food applications, detection methods could meet parameters such as accuracy level, efficiency, quickness, specificity, sensitivity, and non-labor intensive. This review provides an overview of conventional and advanced techniques used to detect foodborne pathogens over the years. Therefore, the scientific community, policymakers, and food and agriculture industries can choose an appropriate method for better results.

A Comparison Between Robotic-Assisted Scaphoid Screw Fixation and a Freehand Technique for Acute Scaphoid Fracture: A Randomized, Controlled Trial

PURPOSE

We compared robotic-assisted scaphoid screw fixation to conventional technique in terms of accuracy, surgical times, radiation exposure, and clinical outcomes, including range of motion, grip strength, functional score, and complications.

METHODS

This study was a registered, prospective, randomized, controlled trial. From May 2019 to December 2019, 1 surgeon performed 18 robotic-assisted and 18 conventional scaphoid screw fixations and these patients were eligible for participation in this study. Surgical time, including the time of the overall procedure, set-up time, and time for ideal guidewire placement, was recorded. The number of guidewire attempts also was recorded. All patients were evaluated clinically and radiographically at follow-up with respect to the severity of pain, wrist motion, grip strength, complications, and Mayo modified wrist score.

RESULTS

The average set-up time and overall time of the procedure were longer in the robotic-assisted than in the conventional groups, while the mean guidewire insertion time and the mean guidewire attempts was less in the robotic-assisted group than that of the conventional group. The overall radiation exposure was lower in the robotic group.

CONCLUSIONS

Robotic-assisted technique provided a useful tool to improve implantation accuracy and shorten radiation exposure. Additional cost and prolonged duration of surgery without evidence of improved clinical scores may limit widespread acceptance of this technique.

A prospective, randomized study evaluating the pain felt during intrauterine device insertion by the direct technique vs conventional technique

OBJECTIVE

To assess the value of the direct insertion technique compared to the conventional insertion technique in reducing the pain experienced during placement of an intrauterine device (IUD).

METHODS

A prospective, controlled, randomized, single-blind trial was conducted in women eligible for IUD insertion. Participants were randomized into two groups: "conventional placement" and "direct placement". The primary endpoint was the percentage of women reporting pain scored as ≥ 4 on the Numerical Verbal Rating Scale (NVRS) at IUD release. Secondary endpoints comprised the number of immediate incidents (insertion failure, vasovagal reaction, and IUD expulsion), the correct positioning of the IUD, checked by ultrasound, the occurrence of incidents within the week following IUD insertion, and the operators' evaluation of the procedure.

RESULTS

A total of 60 patients were enrolled. During IUD insertion, 27 women (45.8%) reported an NVRS score ≥ 4, 32.1% in the "direct placement" group and 58.1% in the "conventional placement" group (p = 0.07). The median NVRS pain scores in the "direct placement" and "classic placement" groups were 2 and 4, respectively (p = 0.01). No statistically significant between-group differences were found with regard to the secondary endpoints.

CONCLUSION

Use of the direct technique reduced the pain experienced during IUD placement. We observed a trend towards a decreased proportion of patients reporting an NVRS pain score ≥ 4 at IUD release with use of the direct technique and the median pain intensity scored on the NVRS was significantly lower in this group. The two techniques did not differ with respect to complications.

Comparative study of manual liquid-based cytology (MLBC) technique and direct smear technique (conventional) on fine-needle cytology/fine-needle aspiration cytology samples

Background:

Liquid-based cytology technique enables cells to be suspended in a liquid medium and spread in a monolayer, making better morphological assessment. Automated techniques have been widely used, but limited due to cost and availability.

Aim:

The aim was to establish manual liquid-based cytology (MLBC) technique on fine-needle aspiration cytology (FNAC) material and compare its results with conventional technique.

Materials and Methods:

In this study, we examined cells trapped in needles hub used for the collection of FNAC samples. 50 cases were examined by the MLBC technique and compared with the conventional FNAC technique. By centrifugation, sediment was obtained and imprint was taken on defined area. Papanicolaou (Pap) and May-Grünwald Giemsa (MGG) staining was done. Direct smears and MLBC smears were compared for cellularity, background, cellular preservation, and nuclear preservation. Slides were diagnosed independently by two cytologists with more than 5 years’ experience. Standard error of proportion was used for statistical analysis.

Results:

Cellularity was low in MLBC as compared with conventional smears, which is expected as remnant material in the needle hub was used. Nuclei overlap to a lesser extent and hemorrhage and necrosis was reduced, so cell morphology can be better studied in the MLBC technique. P value obtained was <0.05.

Conclusion:

This MLBC technique gives results comparable to the conventional technique with better morphology. In a set up where aspirators are learners, this technique will ensure adequacy due to remnant in needle hub getting processed
