intralesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum PC. Patients were instructed to follow a strict routine, involving daily modeling of erect penis and stretching at the urinary toilette time, two minutes each. Success was defined as a decrease in PC of ≥20° from baseline.RESULTS: Sixty-five patients were included in the analysis. Median age was 59.0 years (interquartile range [IQR], 53.0 to 63.0 years), median curvature 40.0° (IQR, 30.0° to 45.0°) median duration of the disease 12.0 years (IQR, 6.5 to 24.0 years). Fifty-three patients (81.54%) had ventral PC, 7 (10.77%) hourglass PC, and 5 (7.69%) shortening PC. Median changes of PC were −20.0 (IQR, −20.0 to −10.0; p<0.01) in ventral PC, −20.0 (IQR, −20.0 to 0; p<0.01) in hourglass and −15.0 (IQR, −15.0 to −15.0; p<0.01) in shortening PC. At Kruscal–Wallis test, significant differences between groups were not found. The rate of PC success was 56.60% (30/53) in ventral PC, 57.14% (4/7) in hourglass and 20.00% (1/5) in shortening PC (p=0.29). Treatment success was not influenced by characteristics of curvature (odds ratio=0.66; p=0.20).CONCLUSIONS: CCH intralesional injections could represent an effective therapeutic option for the conservative management of patients with atypical PC.]]>

BACKGROUND AND OBJECTIVES: Oral ulceration is one of the most common debilitating condition that affects the oral cavity. In this study, the effect of locally injected platelet rich plasma (PRP) and bone marrow-derived mesenchymal stem cells (BMSCs) on the healing of oral ulcer was investigated. METHODS AND RESULTS: An ulcer was induced in buccal mucosa of rats by using 5mm biopsy punch followed by application of cotton swab soaked with formocresol for 60sec. The ulcer was left untreated in the control group, treated with intralesional injection of PRP, or isolated cultured BMSCs. Data were analyzed clinically, histologically and immunohistologically on day 3, 5, 7 and 10. BMSCs group showed smaller ulcer area throughout the whole experimental period than the other groups with complete resolution of the ulcer on day 10, unlike the control group. However, there was no significant difference with PRP, on day 5, 7 and 10, regarding clinical ulcer size. BMSCs group showed better histological results regarding the rate of epithelial cell migration, the number of inflammatory cells, thickness and organization of collagen fibres and the number of blood vessels, with complete re-epithelization on day 10. BMSCs group showed a greater number of anti-PCNA positive nuclei throughout the whole experimental period than the other groups except on day 5, PRP had higher mean numbers of anti-PCNA positive nuclei in both tissues. CONCLUSIONS: Both PRP and BMSCs accelerate wound healing and enhance the quality of the healing tissue with the latter being slightly more effective and faster.

A 61-year-old man presented with a 3-year history of erythematous firm nodules on the hands and feet. Histopathological findings of the lesional skin revealed perivascular and diffuse neutrophilic infiltrations on the upper and mid-dermis. Increased and dilated blood vessels were observed in the upper dermis. Fibrinoid necrosis of the vessel walls was unremarkable, but endothelial swelling and scant red blood cell (RBC) extravasation were noted. Fibrosis and sclerosis of collagen fibers were noted on the deep dermis. Results of laboratory examinations, including complete blood count (CBC), routine chemistry, c-reactive protein (CRP), syphilis and human immunodeficiency virus (HIV) tests, and serum immunoglobulin electrophoresis, were all negative or within normal limit. A diagnosis of erythema elevatum diutinum was made based on the clinical and histological findings. The patient was treated with prednisolone, dapsone, colchicine, and intralesional injection of triamcinolone and showed slight improvement after treatment for 8 months.

BACKGROUND: Cutaneous leishmaniasis is a tropical infection of public health importance. Numerous treatment approaches are in practice with variable degree of success however its management has no universal consensus or practice guidelines to follow. OBJECTIVE: Analyze the management of cutaneous leishmaniasis retrospectively at a central hospital of Jazan Province, Kingdom of Saudi Arabia to identify the current treatment pattern and compare the outcomes. METHODS: This cross-sectional study was conducted based on the hospital records of patients who attended the dermatology clinic for cutaneous leishmaniasis during the year 2012 to 2015. RESULTS: Forty three patients were included in the study. There was a male preponderance (65.1%) among the patients and 60.5% of them were of pediatric age group. Monotherapy was the initial choice for 58.1% of the patients. Intralesional sodium stibogluconate (SS-IL) was the most preferred treatment for initial therapy, as monotherapy and as part of combination therapy. A complete response was achieved in 22 patients (51.2%) with initial therapy. Among the different treatment groups, SS-IL+itraconazole showed significantly higher complete response rate compared to other treatments offered as initial therapy (p<0.01). Initial SS-IL monotherapy provided complete response in 41.2% patients receiving it, while itraconazole monotherapy provided complete response in 75% and 90.9% of the patients receiving initial itraconazole+SS-IL combination therapy with achieved complete response. CONCLUSION: The findings and observations suggest that initial combination therapy with SS-IL+itraconazole significantly improved the complete response rates and thus reduced the need for additional or prolonged therapies.

Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 32-year-old woman with triamcinolone-induced immediate hypersensitivity reaction, in which the patient had a positive prick test result with triamcinolone. She has had atopic dermatitis (AD) for three years. She had used systemic steroid, cyclosporine, and antihistamine with topical steroids for AD. In clinic, approximately 10 minutes after intralesional injection of triamcinolone, she complained of erythematous patches with slight elevation and itching on the face, trunk, and both hands. After intravenous injection of dexamethasone, her symptoms got worse. After treatment with epinephrine, all symptoms resolved within two hours. We performed an open test and skin prick test. She had a positive result only from the prick test with triamcinolone; all other steroids showed negative results from the open tests. Dermatologists should be aware of the possibility of anaphylaxis or other allergic hypersensitivity in response to corticosteroids.

BACKGROUND: Trap-door deformity is a biophysical phenomenon in which U-, C-, or V-shaped linear scars tend to become depressed and the tissue circumscribed by them tends to bulge. The aim of the present study was to demonstrate the efficacy of triamcinolone acetonide (TCA) injection and subcision as a first-line treatment for post-traumatic acute trap-door deformity. METHODS: In trap-door deformity patients, a subcision was made by cutting the fibrotic band along the scar line in the depression using a 22-gauge needle. TCA was administered. An intralesional injection was made along areas of scarring that were difficult to penetrate with the needle. Scar quality parameters were assessed at each follow-up by a single observer and the patient, using the patient and observer scar assessment scale (POSAS) with an additional question about bulging. RESULTS: The average POSAS score per question on the observer scale improved from 6.6±1.31 to 3.6±1.08, and the average POSAS score per question on the patient scale improved from 5.5±1.57 to 2.5±1.26. The average bulging score on the observer scale decreased from 6.0±0.98 to 3.0±0.83, and that on the patient scale decreased from 5.0±1.67 to 2.0±1.30. The average general opinion score on the observer scale decreased from 5.5±1.12 to 3.5±0.91, and that on the patient scale decreased from 6.0±1.84 to 2.0±0.79. CONCLUSIONS: Better outcomes can be obtained by using both TCA and subcision as the first-line therapy for post-traumatic acute trap-door deformity.

PURPOSE: Early application of protease inhibitors through the intestinal lumen could increase survival following experimental shock by blocking the pancreatic digestive enzymes. Hence, it was hypothesized that two-route injection (intraintestinal + intravenous) of ulinastatin (UTI), a broad-spectrum protease inhibitor, could better alleviate intestinal injury than single-route injection (either intravenous or intraintestinal). METHODS: A sepsis model induced by lipopolysaccharide on rats was established. The rats were randomly divided into five groups: sham, sepsis, UTI intravenous injection (Uiv), UTI intraintestinal injection (Uii), and UTI intraintestinal + intravenous injection (Uii + Uiv) groups. The mucosal barrier function, enzyme-blocking effect, levels of systemic inflammatory cytokines, and 5-day survival rate were compared among groups. The small intestinal villus height (VH), crypt depth (CD), and two components of mucosal barrier (E-cadherin and mucin-2) were measured to evaluate the mucosal barrier function. The levels of trypsin and neutrophil elastase (NE) in the intestine, serum, and vital organs were measured to determine the enzyme-blocking effect. RESULTS: Compared with the single-route injection group (Uiv or Uii), the two-route injection (Uii + Uiv) group displayed: (1) significantly higher levels of VH, VH/CD, E-cadherin, and mucin-2; (2) decreased trypsin and NE levels in intestine, plasma, and vital organs; (3) reduced systemic inflammatory cytokine levels; and (4) improved survival of septic rats. CONCLUSION Two-route UTI injection was superior to single-route injection in terms of alleviating intestinal injury, which might be explained by extensive blockade of proteases through different ways.

Peyronie's disease (PD) is an inflammatory disorder characterized by an abnormal collagen deposition in the tunica albuginea of the penis, leading to fibrous and non-compliant plaques that can impede normal erection. Although pharmacological treatments are available, only intralesional injection therapy and surgical reconstruction have demonstrated tangible clinical efficacy in the management of this condition. Intralesional injection of collagenase clostridium histolyticum (CCH) has come to the forefront of minimally invasive treatment of PD. In this review, the authors provide an update on the safety, efficacy, and indications for CCH. The efficacy of CCH will be assessed on the basis of improvement in the severity of penile fibrosis, curvature, and pain. Numerous well-designed clinical trials and post-approval studies involving more than 1,500 patients have consistently demonstrated the efficacy and tolerability of CCH in the treatment of PD. CCH significantly decreases penile curvature and plaque consistency, as well as improves quality of life. Post-approval studies continue to demonstrate the efficacy of CCH despite broader inclusion criteria for treatment, such as the case with acute phase disease and atypical plaque deformities (i.e., ventral plaques, hourglass narrowing). CCH continues to be the gold standard for non-surgical management of stable phase PD, in the absence of strong evidence supporting oral therapy agents and ongoing evaluation of extracorporeal shockwave therapy. However, recent studies are beginning to provide precedent for the use of CCH in the management of acute phase and atypical PD.

PURPOSE: To report the patient characteristics and treatment outcomes in 12 cases of orbital lymphangioma. METHODS: In this study, orbital lymphangioma was diagnosed based on clinical, radiologic (computed tomography, magnetic resonance imaging), and histologic findings when possible. Patients whose vision was not compromised by orbital lymphangioma, or that did not have increased intraocular pressure (IOP), received oral corticosteroids. Orbital lymphangioma that affected vision or increased IOP was treated by surgery, which included aspiration of blood or partial resection with or without injection of a sclerosant. RESULTS: Four patients without compromised vision responded well to oral corticosteroids. Eight patients with compromised vision underwent some form of surgery. Bleeding recurred in three patients after aspiration of blood and in two after partial resection and intralesional injection of a sclerosant. Overall, five patients were treated successfully by aspiration of blood, intralesional injection of a sclerosant, and application of continuous negative pressure by appropriate drainage. Partial resection was successful in two patients with organized hematoma. CONCLUSIONS: Orbital lymphangioma that does not compromise vision can be treated medically using oral corticosteroids. Patients with threatened vision or elevated IOP due to acute hemorrhage should be treated by aspiration of blood, intralesional injection of a sclerosant, and application of continuous negative pressure. Partial resection may be effective only in patients with organized hematoma.

Primary cutaneous anaplastic large cell lymphoma (PCALCL) is a rare primary cutaneous lymphoma that is predominantly composed of large lymphoid cells that express the CD30 antigen. The skin lesion of PCALCL is usually single, ulcerative, and located on the trunk or extremities and rarely the palm. A 25-year-old woman presented with a plaque on the left palm for 20 days. The plaque was walnut-sized and purple to gray colored with erosion in the center. Histopathologic examination showed infiltration of large atypical cells in the dermis. The large tumor cells showed positivity for CD3, CD4, and CD30 and negativity for CD8, CD20, epithelial membrane antigen, and anaplastic lymphoma kinase. PET-CT showed no other hypermetabolic lesion except that on the left palm, and we finally arrived at a diagnosis of PCALCL. The patient was treated with an intralesional injection of methotrexate (25 mg/mL, 0.45 cc). After 3 months of treatment, the walnut-sized plaque had disappeared and a peripheral hyperpigmented patch remained.
