Background: In the tubularized incised plate (TIP) procedure, flap interposition between the skin and neourethra is highly recommended to decrease the postoperative fistula rate. However, there is no consensus regarding the ideal flap for this procedure. This study aimed to report our experiences in the one-stage TIP hypospadias surgery utilizing dartos flap (DF) (penile skin subcutaneous tissue) and tunica vaginalis flap (TVF) (parietal layer of the testis) as a tissue coverage of neourethra. Methods: In a retrospective study from Sep 2018 to May 2021, 16 cases of hypospadias with different types, ranging from midpenile to penoscrotal types, were managed with TIP urethroplasty using DF or TVF as a tissue coverage of neourethra were enrolled. The demographic characteristics of the participants, type of hypospadias, outcome, and complications were analyzed and compared. Results: We used TVF and DF as soft tissue coverage in 11 (68.8%) and 5 (31.3%) patients, respectively. The mean age was 56.38 ± 47.83 months. Mid-penile, proximal, and penoscrotal hypospadias were presented in 3 (18.8%), 8 (50.0%), and 5(31.2%) patients, respectively. The total success rate was 14 (87.5%), while 2 (12.5%) patients developed a urethrocutaneous fistula, which required delayed closure later. In comparison between TVF and DF groups: the TVF was applied in all patients with moderate and severe chordee and all patients with penoscrotal hypospadias, and six patients with proximal hypospadias, while only three patients with mild chordee and two patients with proximal hypospadias used the DF and showed statistical significance between groups (p < 0.001 and 0.012) respectively. The success rate was 90.9% vs. 80.0% in TVF and DF groups, respectively, with no statistical significance between groups (p = 1.000). Conclusions: In the primary TIP repair, the TVF is a practical option as a DF for the interposition cover of a neourethra, especially in penoscrotal and proximal hypospadias with severe chordee.

Congenital diaphragmatic hernia (CDH) is known as a structural defect caused by inadequate fusion of the pleuroperitoneal membrane forming the diaphragm, allowing peritoneal viscera to protrude into the pleural cavity. It affects nearly one out of 2500 live births. We here report the case of a six-month-old boy with left diaphragmatic hernia presenting with poor feeding, breathing difficulty, cough, and recurrent pneumonia in the last 2 months. Chest X-ray and computed tomography scan revealed left sided CDH. The defect was corrected through open surgical repair without complications. At 5-month follow-up a radiograph was performed which revealed full recovery. The primary goal of this report was to alert physicians to suspect this diagnosis in patients with unexpected presentation of diaphragmatic hernia.

Background: Recently, biological dressings have become popular in treating burn injuries. Fish skin has non-infectious microbiota, high levels of type 1 and type 3 collagen, and a structural property similar to human skin, making it a promising xenograft for managing burn wounds. In this study, we aimed to evaluate the effectiveness of fish skin as a physiological dressing cover in patients with burn injuries. Method: From June 2017 to June 2021, 18 patients who were admitted to our center within 3 days from a thermal injury, burns with a partial thickness of approximately 20% of the total body surface area (TBSA) or complete partial-thickness burns ranging from 5% to 15% of the TBSA, and treated with the Shaour (Lethrinus lentjan) fish skin xenografts were enrolled in this retrospective study. The demographic characteristics of the participants, wound healing process, and final outcome were analyzed. Results: The mean age of the patients was 31.86 ± 9.14 years (range 19–46) which encompassed 12 (66.7%) men and 6 (33.3%) women. Superficial partial-thickness burns were seen in 13 (72.2%) patients, whereas full-thickness burns were seen in five (27.8%) patients. The mean time to 90% epithelialization and 100% epithelialization were 11.05 ± 2.57 days and 17.27 ± 2.05 days, respectively. The mean pain scores were 6.94 ± 0.72 and 5.22 ± 0.64 on days 7 and 15, respectively. Neither negative consequence nor allergic reaction was associated with using the fish skin grafts. The main reduction in the pain score from the first visit (7 days) to the second visit (15 days) was 1.72 ± 0.95 (p <  0.001). Conclusion: Acellular fish skin is a useful tool for wound healing treatment in complete and partial thickness burns. To validate this result, prospective cohort studies with long-term post-procedural follow-up are needed.
