Transurethral Removal of Vesical Fungal Bezoar Using Ho:YAG LASER—A Case Report

Padmaraj Hegde — 2024-10-10

Fungal bezoars are extremely rare in the urinary bladder, and there is limited literature regarding the modality of management. We report a case, where the piecemeal removal of a vesical fungal bezoar was performed using Ho:YAG LASER. A 60-year-old man presented with lower urinary tract symptoms and on evaluation was diagnosed with vesical calculus. On cystoscopy, a white-colored, smooth contoured ball was identified in the bladder. The effective endourological modalities for the removal of fungal bezoar require mention in the literature. This case report demonstrates the possibility and efficiency of Ho:YAG LASER in the endourological retrieval of fungal bezoar in the bladder. The rarity of the diagnosis results in difficulty in prompt management.

Wide-Awake Local Anesthesia No Tourniquet (WALANT) Technique: A Case Report Demonstrating Its Cost-Effectiveness in a Resource-Limited Setting

Charandeep Singh Juttla — 2024-10-10

Wide-Awake Local Anesthesia No Tourniquet (WALANT) offers a cost-effective alternative to general anesthesia (GA) for wound debridement, improving patient safety, surgical accessibility, and cost-efficiency. This study explores WALANT’s cost-effectiveness and patient outcomes in a resource-limited setting. The patient, E.M., a 27-year-old woman, presented with left upper limb swelling, which began a week after Implanon device removal at another facility. Upon admission, she displayed severe sepsis symptoms, including a blood pressure of 100/58 mmHg, a heart rate of 144 beats per minute, a respiratory rate of 24 breaths per minute, and a temperature of 39.2℃. Her left upper limb showed swelling, redness, and shininess, leading to a diagnosis of necrotizing fasciitis with septic shock. Initially, wound debridement was conducted under GA. However, the patient’ s choice to undergo WALANT for her second debridement saved her 89.1% of the cost of performing debridement under GA. This cost reduction significantly benefited the uninsured patient, alleviating the financial burden and also achieved a favorable patient outcome within the constraints of a resource-limited setting.

Morphological and Morphometric Analysis of Carotid Canal Apertures in the Nigerian Population

Moses Adetona — 2024-10-10

Background: The external opening of the carotid canal (EOCC), the entry point of the internal carotid artery into the skull, varies across populations. This study characterized the EOCC with the mastoid process (shortest distance from the EOCC to the tip of the mastoid process [SDTCC]), the foramen magnum (shortest distance from the EOCC to the foramen magnum [SDFM]), and the midline of the skull base (shortest distance from the EOCC to the midline of the base of the skull [SDMCC]) in the Nigerian population.

Materials and Methods: Fifty skull base pictures were taken in the plumed position with a digital camera. Measurements were taken using Image J software, and Euclidean distances were calculated. The shapes of the EOCC were noted. Paleontological Statistics (PAST 3.0) was used to perform descriptive statistics. Paired ttest and Pearson correlation were used to compare bilateral values and the relationship between the parameters, respectively.

Results: The length (right, 0.53 [standard deviation (SD)=2.5] mm; left, 10.99 [SD=2.84] mm) and width (right, 13.96 [SD=2.43] mm; left, 14.16 [SD=2.09] mm) of the EOCC were recorded. In contrast to the populations in South Africa, Serbia, and India, the length of the EOCC obtained from this study is shorter than the breadth. The length of SDFM (right, 41.04 mm; left, 44.13 mm), SDMCC (right, 58.4 mm; left, 57.97 mm), and SDTCC (right, 57.29 mm; left, 55.61 mm) was established among Nigerians.

Conclusion: The Nigerian population showed EOCC of shorter length than the breadth compared to other populations, and the size of the skull is independent of the foramina size. These dimensions may provide information for procedures that affect the skull base.

Diagnostic Accuracy of Bethesda Classification of Thyroid Nodules at a Kenyan Hospital: A Retrospective Study

Aurelia Brazeal — 2024-10-10

Background: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was developed to standardize the reporting of thyroid nodule fine-needle aspiration cytology (FNAC) results. The adoption of TBSRTC is based on the implied risk of malignancy per category, but this has shown wide variation in different regions worldwide.

Aim: The aim of this study is to determine the diagnostic accuracy of the Bethesda classification of thyroid nodules in a Kenyan hospital.

Methods: A retrospective longitudinal study examined FNAC and histopathology data of thyroid gland nodules at a Kenyan hospital from 2010 to 2019; specimens from 347 patients were found. An analysis was performed to determine the diagnostic accuracy of the Bethesda classification in detecting malignancy among these patients.

Results: The malignancy rate was 16.1%. The risk of malignancy as per the Bethesda category was as follows: non-diagnostic— 19.6%, benign—6%, atypia of undetermined significance—20%, follicular neoplasm—16.7%, suspicious for malignancy—80%, and malignant—85.7%. The diagnostic properties of FNAC defining “malignant” and “suspicious for malignancy” categories as malignant were as follows: sensitivity—64.7%, specificity—97.6%, and accuracy—92.7%.

Conclusion: The Bethesda classification had high diagnostic accuracy, with the risk of malignancy consistent with the Bethesda findings. Classifying malignancy as “malignant” and “suspicious for malignancy” yielded the most favorable diagnostic properties for FNAC.
