Necrosis of the colon as a complication of shock

Colonic necrosis secondary to hypotension and shock in previously healthy, young patients is a rare occurrence with only ten cases reported in the literature. In all but one instance the necrosis was limited to the right colon. Three additional cases of transmural necrosis involving both the right and left colon following a documented episode of shock are reported. Two cases were related to hemorrhagic shock following trauma and the third case followed a drug overdose with associated hypotension. An episode of hypotension was the common denominator in all cases previously reported. The lowest mean blood pressure in the present series was 35 mmHg. A diagnosis of subtotal colonic infarction was made at laparotomy in these three patients two to nine days after the initial hypotensive episode. Pathologic examination of the excised colon revealed transmural necrosis in all three cases with no evidence of a thrombotic or embolic process accounting for the colonic necrosis. The etiology was felt to be a low flow state within the splanchnic circulation. The data suggests that patients who present with a history of prolonged hypotension and shock are at risk for the development of colonic infarction. Successful management involves early diagnosis and resection of the infarcted colon.     

Gangrene of the penis as a complication of penile prosthesis

Gangrene of the penis is rare but several factors acting simultaneously may produce this condition. These factors include local infection, pressure dressing, presence of a urethral catheter, edema and ischemia of the corpus cavernosum. We report a case of iatrogenic gangrene of the penis following implantation of a Scott inflatable penile prosthesis, and all of the aforementioned factors were present.     

Necrosis of the galea as rare complication of infection of a traumatic temporal hematoma

Authors report a case of infective traumatic temporal haematoma causing septic focus. The suppurative inflammation developed two weeks after the trauma causing necrosis of an extensive part of the galea on a big area of the crown of head. A septic process increased producing necrotic alteration of the affected periosteum of the cranial bone and plegmon in the tissue of the neck. Authors report the surgical plastic procedures that were used to establish a granulating layer and to cover the surface in the area of the removed necrotic part of the galea. Authors emphasize the significance of the danger of the inflammatory infiltration and report the effect of the Curiosin solution on the wound-healing.     

Pneumomediastinum as a complication of recreational ecstasy use

Ecstasy recreational use dramatically increased during the last decade in France. Multiples complications associated with ecstasy consumption have been reported. We describe an exceptional case of pneumomediastinum related to ecstasy recreational use. The patient was a 19-year old patient whose medical history was significant for asthma and was a moderate tobacco smoker. He reported regular ecstasy recreational use. He presented at the emergency unit for chest pain and cough, 48 hours after the ingestion of three tablets of ecstasy and the inhalation of three other tablets. Blood pressure was 90/60 mmHg, pulse rate was 120 per minute, respiratory rate was 32 per minute and pulse oximetry was 93%. Neck emphysema was noted. Chest radiograph and scanner diagnosed pneumomédiastinum. Outcome was favorable with symptomatic treatment and the patient was discharged home eight days later. Pneumomediastinum is an exceptional complication after ecstasy recreational use. Physician should be aware of the risk of such event.     

Buried penis in adults as a complication of circumcision: Surgical management and long-term outcomes

We aimed to evaluate the feasibility and long-term functional outcomes of surgical correction of adult buried penis patients due to complications of childhood circumcision. A retrospective analysis was performed for patients who underwent treatment for buried penis between 1997 and 2019. An autologous split-thickness skin graft (STSG) was used. Surgical management steps included circumcision, resection of the bands between the corpora and other tissues, harvesting of STSG from femoral region and graft application. Surgical and functional outcomes were the primary end points. Thirteen patients were included with a mean age of 22.4 years and median body mass index 27. Patients had similar symptoms, including sexual dysfunction, inadequate penile length, impossible penetration and decreased quality of life. No early post-operative complication was seen. During a median of 44-month follow-up, post-operative long-term complications were seen in 4 (30%) patients: decreased graft sensation (n = 2); graft contracture five months after surgery (n = 1); and retarded ejaculation (n = 1). Patients’ post-operative three-month International Index of Erectile Function (IIEF) score and sexual satisfaction score (SSS) significantly increased compared with patients’ pre-operative scores (IIEF; 22.8 vs. 14.1, p = .03, SSS; 8.7 vs. 3.2, p < .01). Buried penis is a rare but challenging condition. Patients had excellent graft acceptance with successful functional outcomes.     

Subdural abscess as a complication from use of the halo device

Summary Complications associated with the application of a halo device are not infrequent; however, osteomyelitis of the skull with a consecutive subdural abscess is a rare but severe complication. We present the case of a patient with a subdural abscess as a result of a local pin-track infection of the halo device, in whom pathological behavior was the primary clinical finding. The possible complications associated with the halo device are discussed with emphasis on associated head injuries and preexisting neurological diseases, as well as indications for the halo, clinical symptoms of pin-track infections, necessary diagnostic measurements and the appropriate treatment.      

Common skin disorders of the penis

Diseases of the male genitalia range from infectious lesions to inflammatory and neoplastic conditions, including many genital manifestations of more general skin diseases. This review highlights the clinical features, diagnosis and treatment of the most common dermatoses of the male genitalia. Herpes genitalis and infections caused by human papillomavirus (HPV) are increasing, particularly in young sexually active people. Herpes simplex virus infection is the commonest infectious cause of genital ulceration, with evidence that many infections are asymptomatic. HPV infection may be latent, subclinical and clinical. The most common causal agents for condyloma acuminatum are low-risk HPV 6 and 11; high-risk HPV types 16 and 18 are associated with premalignant and malignant lesions. Treatment for genital warts remains unsatisfactory; recurrences are common. Imiquimod, a new topical immunotherapeutic agent, which induces interferon and other cytokines, has the potential to be a first-line therapy for genital warts. Scabies and pediculosis are transmitted by skin-to-skin contact and sexual transmission is common, with the penis and scrotum favourite locations for scabious lesions. Oral ivermectin, a highly active antiparasitic drug, is likely to be the treatment of choice, but until approval is granted it should be reserved for special forms of scabies. Common skin diseases, e.g. psoriasis and lichen planus, may have an atypical appearance in the genital area. The typical psoriatic scale is usually not apparent because of moisture and maceration. Allergic contact dermatitis of the genital area may result from condoms, lubricants, feminine hygiene deodorant spray and spermicides. More often, contact dermatitis is irritant, resulting from persistent moisture and maceration. Lichen sclerosus is a chronic inflammatory disease that occurs as atrophic white patches on the glans penis and foreskin. The penile form is a common cause of phimosis in uncircumcised men; involvement of the urethral meatus may lead to progressive meatal stenosis. Plasma cell balanitis is a benign, idiopathic condition presenting as a solitary, smooth, shiny, red-orange plaque of the glans and prepuce of a middle-aged to older man. Squamous cell carcinoma (SCC) in situ, e.g. erythroplasia of Queyrat and Bowen's disease, cannot be excluded clinically; their apparent clinical benignity may lead to lengthy periods of misdiagnosis and biopsy is required to confirm the diagnosis. SCC is the most common malignancy of the penis and the role of oncogenic HPV-types has been also established in SCC of the penis. Prevention of SCC of the penis presupposes an identification of risk factors, early detection of all pre-cancerous lesions and treatment of phimosis.     

Concealed penis: rare complication of circumcision

A man presented with a concealed penis which developed after circumcision. In addition to anatomic variations in penile skin attachment and obesity, circumcision is an iatrogenic cause in the etiology of a concealed penis. Although it is a frequent and simple operation, it may lead to uncommon complications due to a lack of experience and poor technique.     

Compartment syndrome as a complication of the prolonged use of the Lloyd-Davies position

Compartment syndrome in the legs is a rare complication of the prolonged use of the lithotomy position. We report two cases of compartment syndrome developing as a complication of the prolonged use of the Lloyd-Davies position. Both patients received combined general and epidural anaesthesia and postoperative epidural analgesia. The diagnosis was delayed in the first case, resulting in the avoidable complications of renal failure and permanent neuromuscular dysfunction.
