Hyperbaric oxygen treatment in bilateral orchiopexy and post-circumcision haematoma in a thrombocytopenic patient with Noonan syndrome.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

US of the Penis: Beyond Erectile Dysfunction.

High-frequency US, with a linear transducer and gray-scale, color, and spectral Doppler US techniques, is the primary imaging modality for evaluation of the penis. It can allow delineation of anatomy and assessment of dynamic blood flow; it is easily available and noninvasive or minimally invasive; it is cost effective; and it is well tolerated by patients. US assessment after pharmacologic induction of erection is an additional tool in assessing patients with suspected vasculogenic impotence, and also in selected patients with penile trauma and suspected Peyronie disease. Penile injuries, life-threatening infections, and vascular conditions such as priapism warrant rapid diagnosis to prevent long-term morbidities due to clinical misdiagnosis or delayed treatment. US can facilitate a timely diagnosis in these emergency conditions, even at the point of care such as the emergency department, which can facilitate timely treatment. In addition, color and spectral Doppler US are valuable applications in the follow-up of patients treated with endovascular revascularization procedures for vasculogenic erectile dysfunction. Image optimization and attention to meticulous techniques including Doppler US is vital to improve diagnostic accuracy. Radiologists should be familiar with the detailed US anatomy, pathophysiologic characteristics, scanning techniques, potential pitfalls, and US manifestations of a wide spectrum of vascular and nonvascular penile conditions to suggest an accurate diagnosis and direct further management. The authors review a range of common and uncommon abnormalities of the penis, highlight their key US features, discuss differential diagnosis considerations, and briefly review management. ©RSNA, 2024 Supplemental material is available for this article.

Evaluation of Smooth Muscle Myosin Heavy Chain Isoform Expressions in a Buried Penis.

BACKGROUND: A buried penis (BP) is rare in which the penile body is retracted into the prepubic adipose tissue. This research focuses on differences in smooth muscle myosin heavy chain (SMMHC) isoform expressions in the dartos fascia. METHODS: A total of 82 children, 41 of whom had BPs, who applied for circumcision between May and November 2021, were included in the study. The cases were divided into four groups aged ≥6 years (NP6, n = 18) and aged ≤3 years (NP3, n = 17) with normal penile appearance, aged ≥6 years (BP6, n = 23) and aged ≤3 years (BP,n = 24) with a BP. SMMHC isoforms mRNA gene expression analyses were performed by quantitative PCR technique in dartos fascia obtained from foreskin removed by circumcision. RESULTS: Compared to the NP3 group, the SM1 mRNA expressed in the BP6 group was statistically significantly higher (p < 0.005). SM2 mRNA levels expressed in dartos fascia were considerably higher in NP6 and NP3 groups compared to BP6 and BP3 groups (p < 0.001). The SM2/SM1 ratio was 0.85 in the BP6 group and 1.46 in the NP6 group, which was statistically significant (p = 0.006) and increased from 0.87 in the BP3 group to 2.21 in the NP3 group (p < 0.001). CONCLUSION: In a buried penis, there is a difference in the expression of SMMHC isoforms. SM1 is highly expressed, while SM2 decreases, increasing the SM2/SM1 ratio. This causes increased contractility in the smooth muscle, leading to retraction of the penile body. The dartos fascia surrounding it resembles aberrant muscle tissue in boys with a BP. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Case-control study.

Surgical treatment and outcomes of acute and chronic ulcers on the penis following injection of foreign substances.

In this paper, we present our experience with acute and chronic penile ulcers resulting from injection of an exogenous substance and their surgical treatment.

[Clinical case of penile fracture].

A clinical case of a penile fracture as a result of an unsuccessful sexual intercourse, which later required surgical treatment in the form of corporoplasty with opening and draining of the hematoma, is discussed in the article. Penile fracture is a rare urological emergency that requires immediate medical attention to avoid long-term complications, including penile curvature and erectile dysfunction.

The effects of topical aloe vera on an experimentally designed penile fracture model in rats.

BACKGROUND: This study assessed the histopathological and oxidative effects of topical Aloe Vera (AV) on penile fractures (PF) formed experimentally in a rat model. METHODS: Forty Wistar albino rats (220-250 g) were used. The PF model was created experimentally with a number 15 lancet. Then, the rats were randomly and equally divided into five groups. In the first group (C), no incision was formed. In the second group (P), an incision was formed. In the third group (PR), the incision line was closed primarily. In the fourth group (PA), AV was locally applied onto the incision without suturing for three days. In the last group (PRA), AV was applied to the primary repair region for three days. All groups were compared to each other according to histopathological and biochemical data. RESULTS: Hyperemia-bleeding was observed to be suppressed in the PRA group compared to the other groups (p<0.001). Inflammation was observed only in Groups PR and PRA (p<0.001). Significant fibrosis was observed in the PA and PRA groups compared to the other groups (p<0.001). Superoxide Dismutase (SOD) and Glutathione (GSH) values increased in favor of Group PRA (p=0.009 and p=0.035, respectively). Total Oxidative Status (TOS) and Malondialdehyde (MDA) values decreased in favor of Group PA (p=0.036 and p=0.026, respectively). Tumor Necrosis Factor-alpha (TNF-α) and Interleukin-1 beta (IL-1ß) levels decreased mostly in the PRA group, but these changes did not reach statistical significance (p>0.05). CONCLUSION: Topical AV application reduces tissue inflammation and oxidative stress but appears to increase the development of fibrosis after PF.

Evaluation of Z-plasty versus Heineke-Mikulicz scrotoplasty in the management of penoscrotal web in pediatric age group.

BACKGROUND: The penoscrotal web may be congenital or acquired following excessive ventral skin removal during circumcision. Several surgical techniques were described for the treatment of congenital webbed penis without a clear comparison between their outcomes. This prospective study aimed at comparing the surgical results of Z-scrotoplasty and Heineke-Mikulicz scrotoplasty in the treatment of congenital webbed penis in uncircumcised pediatric patients. METHODS: Our study included 40 uncircumcised patients who were divided randomly into two groups; Group A included 20 patients who were treated by Z-scrotoplasty and Group B included the other 20 patients who were treated by Heineke-Mikulicz scrotoplasty. All patients were circumcised at the end of the procedure. RESULTS: The surgical outcome was good without a significant difference between the two groups in 36 patients. Recurrent webbing developed in one patient of Group A and in three patients of Group B (FE p = 0.605) The only significant difference between the two groups was the operative duration which was shorter in Group B than in Group A (P < 0.001*). CONCLUSIONS: Treatment of congenital penoscrotal web in the pediatric age group could be done with either Z-scrotoplasty or Heineke-Mikulicz scrotoplasty with satisfactory results, however, without significant difference in the surgical outcomes.

Surgical management of adult acquired buried penis syndrome: A systematic review of patient-reported outcome instruments.

PURPOSE: Adult acquired buried penis (AABP) is a morbid condition often necessitating surgical intervention. Accurate assessment of pre- and postoperative symptoms is crucial to understand how AABP impacts a patients' quality of life, verify surgical effectiveness, and practice patient-centered care. There is no validated patient-reported outcome instrument specific for AABP evaluation. We undertook a comprehensive review of existing literature on patient-reported outcome instruments post-AABP surgery to highlight the importance of developing a specific tool. METHODS: Following the preferred reporting items for systematic reviews and meta-analysis 2020 guidelines, we queried three databases using relevant keywords (e.g., "buried penis repair"). Inclusion criteria were studies that discussed surgical management of AABP with patient-reported outcomes. Pediatric and congenital cases were excluded. Information collected included study design, level of evidence, number of participants included in the study, etiology of buried penis, surgical technique, preoperative or postoperative patient-reported outcomes, and patient-reported outcome instrument used. RESULTS: Initial query identified 998 records. After abstract screening and applying the inclusion or exclusion criteria, a total of 19 articles with 440 patients were included. Eight studies implemented patient-reported outcome instruments. The international index of erectile dysfunction-5 and Likert satisfaction scales were used most frequently. Although all instruments were validated, none were validated in the specific context of AABP surgical intervention. CONCLUSIONS: There is considerable heterogeneity within the AABP literature regarding patient symptomatology, postoperative complications, patient-reported outcomes, and instruments used. The results of this study emphasize the need for a patient-reported outcome measure to examine the influence of AABP repair on patient satisfaction and health-related quality of life.
