Erythematous Linear Lesion on the Course of Superficial Fibular Nerve After the Topical Application of Black Henna: A Case Report.

Henna is commonly used in body arts, where it produces orange-brown color. It is often mixed with chemicals such as para-phenylenediamine (PPD) to fasten the dyeing process and produce a black color. However, PPD has many allergic and toxic effects. We present a case of henna-induced cutaneous neuritis, which is not reported before. A 27-year-old female presented to our hospital, complaining of pain in her left great toe after applying black henna. Upon examination, the proximal nail fold was inflamed, and an erythematous non-palpable tender lesion was noticed on the dorsum of the foot. The lesion had an inverted-Y shape that was confined to the course of the superficial fibular nerve. Cutaneous nerve inflammation was favored after excluding all the anatomical structures in the region. Black henna should be avoided since it contains PPD, which can be absorbed through the skin and affect the underlying cutaneous nerves.

Isolated Flexor Digitorum Profundus Injuries in Flexor Zone II of the Hand: A Report of Five Cases.

Injuries of the hand's flexor tendons carry a poor prognosis, mainly if they are in zone II (also called 'the critical zone' or 'no man's land'). The superficial tendon in this zone ends by bifurcating and attaching to the sides of the middle phalanx, exposing the deep tendon that attaches to the distal phalanx. Thus, trauma to this zone may result in a complete cut to the deep tendon while the superficial one remains intact. The lacerated tendon, in turn, would be retracted proximally to the palm making it difficult to be found during wound exploration. The complex anatomy of the hand, particularly that of the flexor zones, may contribute to the misdiagnosis of a tendon injury. We report five cases of an isolated cut of the flexor digitorum profundus (FDP) tendon after traumatic injury to the flexor zone II of the hand. The mechanism of injury of each case is reported together with a clinical approach that guides ED physicians toward diagnosing flexor tendon injuries in hand. In cut wounds involving the flexor zone II of the hand, it should be not surprising to find that the deep tendon (FDP) is completely lacerated without an injury to the superficial one (FDS). Therefore, we conclude that a systematic examination approach for traumatic hand injuries is essential to ensure the proper assessment. Understanding the mechanism of injury, performing a systemic examination approach, and having basic anatomical knowledge of flexor tendons of the hand are essential to identifying tendon injuries, anticipating complications, and providing adequate healthcare.

Using Absorbable Sutures for Traumatic Wound Closure to Avoid Additional Hospital Visits for Suture Removal During the COVID-19 Pandemic: A Randomized Controlled Trial.

Introduction The COVID-19 pandemic worldwide forced governments to undertake intervention measures to encourage social distancing. Meanwhile, traumatic skin lacerations require multiple hospital visits for dressing changing and suture removal since they are usually repaired with non-absorbable sutures. These visits can be avoided by using absorbable sutures instead. However, absorbable sutures carry the "potential" risk of wound infection. In the current study, our first objective was to determine the non-inferiority of absorbable sutures regarding infection rate after repairing traumatic wound lacerations in comparison to the conventional non-absorbable ones. Our second objective was to evaluate the superiority of absorbable sutures in regard to postoperative clinic visits for suture removal and wound dressing compared to the non-absorbable ones. Methods A sample of 471 patients with traumatic skin lacerations was analyzed during the COVID-19 pandemic in April 2020. In the control group, wounds were repaired using non-absorbable sutures, while rapid-onset absorbable sutures were used in the treatment group. By conducting a phone/video call follow-up after 21 days, several parameters regarding infection signs and clinic visits were compared between both groups. Results A significant decrease in total trauma patients (45.4%) and those who required suturing (51.2%) was observed in April 2020 compared to the same month of the previous four years (p = 0.001 (2016), p = 0.027 (2017), p = 0.027 (2018), and p = 0.001 (2019)). Regarding wound infection, no statistically significant difference (p = 0.623) was observed between the absorbable (3.2%) and non-absorbable (4.9%) groups. Using absorbable sutures resulted in significantly (p < 0.001) fewer postoperative hospital visits compared to using non-absorbable sutures (mean: one versus three visits). Conclusion Using absorbable sutures to repair traumatic wound lacerations is safe regarding wound healing and infection rates. They also reduce postoperative hospital visits since they are not intended to be removed. Therefore, they should be considered during a pandemic to reduce hospital visits for suture removal, which will subsequently enhance social distancing and relieve hospital load.

Giant omental lipoma, a rare etiology of right-iliac fossa pain in adult: A surgical case report.

BACKGROUND: Omental lipoma is an uncommon abdominal tumor of mature fat cells. Those benign tumors are usually asymptomatic but occasionally can cause signs and symptoms based on their location, size, and presence of complications. Radiological investigations such as Abdominal ultrasonography (USG) and computed tomography (CT) are crucial to evaluate and diagnose intra-abdominal tumors, especially omental lipomas. PRESENTATION: A 61-year-old male patient presented to our hospital with right iliac fossa pain. Physical examination and laboratory test results were normal. The performed abdominal CT scan revealed a large right-sided intraperitoneal mass measuring about 2.4 × 10 × 20 cm. Then, an ultrasound-guided biopsy was done and the picture was most consistent with lipoma. So, surgical intervention was decided and omental lipoma was completely exteriorized via a laparoscopic approach. The weight of the excised omental mass was 2.45 kg, measuring 23 × 18 × 7 cm. The resected specimens, including omental lipoma and omental lymph nodes, were sent for histopathological studies. The postoperative period was uneventful. DISCUSSION: Omental lipoma is an unusual entity that occurs often in children and rarely in adults. The clinical features of omental lipomas include abdominal discomfort, abdominal lump, abdominal pain, nausea, and/or weight loss. Diagnosis of the omental lipoma relies on imaging and physical examination, which was normal in the presented case. Abdominal CT provides definitive fat content characterization and its localization within the omentum. CONCLUSION: Due to the rare etiologic origin of omental lipomas, we report the case of a 61-year-old male with right iliac fossa pain, found to be caused by detected giant omental lipoma.
