Prevotella bivia is an anaerobic, gram-negative bacillus which naturally thrives in the human vagina, and is usually related to vaginal tract infections. However, this microorganism can also cause infections in other body locations. Infections with Prevotella bivia are frequently severe due to the risk of osteomyelitis and the lack of good protocols for adequate therapeutic management. Staphylococcus haemolyticus infection is one of the most frequent etiological factors of nosocomial infections, which hasthe ability to acquire multiple resistance against antimicrobial agents. We report a rare case of foot and hand paronychia with superinfection of Prevotella bivia and Staphylococcus haemolyticus. We highlight the importance of early microbiological diagnosis, and proper therapeutic management to avoid the risk of complications and the development of bacterial resistance to antibiotics.

Background: Ligamentous or joint laxity is a clinical entity characterized by increased joint mobility beyond the range of motion regarded as normal, and joint mobility is an effective indicator of the degree of laxity. We examined the influence of ligamentous laxity on the range of ankle dorsiflexion with the knee flexed and extended, comparing lax adults with a control (nonlax) group. Methods: The sample comprised 400 individuals: 200 in the control group (mean ± SD age, 32.49 ± 11.06 years) and 200 in the lax group (mean ± SD age, 29.82 ± 9.40 years). The Beighton criteria were applied to each participant to diagnose laxity or nonlaxity, and sex, age, and angle range of bilateral dorsiflexion with the knee extended and flexed were recorded. Results: The mean ± SD dorsiflexion range with the knee straight was 16.14° ± 5.29° left ankle and 21.21° ± 4.93° right ankle in the lax group and 12.94° ± 4.17° left ankle and 17.08° ± 4.40° right ankle in the control group. The respective values with the knee flexed were 15.84° ± 5.31° and 21.21° ± 4.80° in the lax group and 12.95° ± 3.95 and 17.23° ± 4.25° in the control group. Conclusions: In this sample, ankle dorsiflexion range in the lax group was 4° bigger than that in the control group in both knee positions.

Iatrogenic burns are unpleasant and sometimes difficult to explain to patients. Podiatric surgeons routinely use electrosurgical devices to cut and coagulate tissue during surgical procedures. Although advances in technology have made electrosurgery increasingly safer for patients and personnel, its use is still poorly understood by the surgical community, and the hazards associated with its use still exist presently. Human error, direct or indirect transfer of electricity to a conductive device, or device malfunction can cause serious adverse events, including burns, electrical shocks, and or fires. Here, we report a rare case of a 43-year-old man who suffered severe burns during hallux valgus surgery. The surgeon and the nursing staff did not notice any injuries during the surgical intervention. This unusual clinical case serves to highlight the importance of implementing protocols to prevent injuries related to the use of electrosurgery. Based on this report, a specific checklist was implemented to prevent adverse events related to electrosurgery in our podiatric surgery unit to reduce the risk of electrosurgical complications. The implementation of the checklist can be useful to help health professionals improve patient safety during surgery and avoid potential medico–legal liability claims.

Lobular capillary hemangioma (LCH-PG) is a type of pyogenic granuloma characterized by proliferating blood vessels that resemble conventional granulation tissue. Granulation tissue is very often seen in association with ingrown toenails. Despite the close relationship between both entities, LCH-PG shows clinically different behaviors, such as rapid growth and frequent recurrence. Currently, it is unknown exactly how the different etiological factors contribute to the formation of differences between entities. We present a case of a large LCH-PG associated with chronic onychocryptosis in a 26-year-old man. Histopathological features included extensive signs of ulceration, hyperkeratosis, and patchy epidermal acanthosis with the presence of fibrous septa with lobular areas beneath the ulcerative area. The presence of stroma with a marked proliferation of blood vessels with wall thickening and mixed-type inflammatory changes was also characteristic. In advanced stages of onychocryptosis, as presented here, conventional granulation tissue or pyogenic granuloma can be clinically difficult to distinguish from other benign or malignant neoplasms. Histological examination is mandatory, and excisional biopsy can provide a definitive diagnosis.
