Taping alone for persistent ventral curvature after urethral plate transection in hypospadias.

INTRODUCTION: Ventral penile curvature is a key factor in determining the surgical approach to proximal hypospadias repair. However, there is limited evidence regarding the efficacy and long-term effects of the procedures used to address curvature. This study aimed to evaluate the effects of urethral plate transection alone with tissue traction therapy on penile curvature in two-stage repair of proximal hypospadias. MATERIAL AND METHODS: This was a prospective study of primary hypospadias patients who underwent a two-stage repair with urethral plate transection as the sole straightening procedure. After stage 1, taping was applied as tissue traction therapy and continued until stage 2. Penile curvature was measured using a goniometer under artificial erection before and immediately after urethral plate transection and during the second stage of repair. The primary focus of this investigation is the angle of curvature after 6-month taping. RESULTS: The study included 46 patients with a median age of 13 months at the start of treatment. The median angle of penile ventral curvature was 70° after degloving, 60° after urethral plate transection, and 0° during the second stage of repair. Full correction of ventral curvature was achieved in 42 patients (91 %). DISCUSSION: This publication is the first of its kind to propose taping as a method for penile traction therapy in hypospadias. The study reveals that penile ventral lengthening can be achieved through tissue traction therapy following UP transection alone. These findings challenge the current consensus that complete straightening of the penis in the first stage is necessary to prevent recurrent curvature and that ventral lengthening is required to correct corporal disproportion. However, further validation and long-term data are needed to definitively confirm the effectiveness of tissue traction therapy after urethral plate transection. CONCLUSIONS: This study demonstrated significant resolution rate of penile ventral curvature in proximal hypospadias following urethral plate transection alone with taping. Long-term follow-up studies are needed to confirm the sustainability of the results through puberty.

Cutaneous infection caused by Purpureocillium lilacinum: Case reports and literature review of infections by Purpureocillium and Paecilomyces in Taiwan.

Hyalohyphomycosis is a rare infection caused by a group of fungi that are devoid of pigments in their cell walls. As one of the main pathogens of hyalohyphomycosis, Purpureocillium lilacinum (former Paecilomyces lilacinus) is known for its intrinsic resistance to various antifungal agents. Here, we report three cases that coincide with a history of farming and all of them suffered from cutaneous hyalohyphomycosis caused by P. lilacinum. They shared a clinical presentation consisting of erythematous-to-violaceous painful plaques with overlying pustules on one of their forearms. Hyphae and fungal elements were highlighted by periodic acid Schiff or Gomori methenamine silver staining in their skin biopsies. Fungal cultures of their skin tissues yielded P. lilacinum, which was confirmed by both morphological and molecular characteristics. All patients responded well to oral terbinafine or itraconazole treatment. In this report, we also reviewed previously reported cases associated with either P. lilacinum or other Paecilomyces spp. infections in Taiwan.

Surgical versus medical treatment for infective endocarditis in patients on dialysis: a systematic review and meta-analysis.

Infective endocarditis (IE) is a serious infection and causes significant morbidity and mortality. However, the benefit of surgery for endocarditis besides antibiotic treatment in dialysis patients remains controversial. We performed a systematic review of studies published between 1960 and February 2022. Meta-analysis was conducted with a random-effects model to explore the in-hospital, 30, 60, 90, 180-d, and 1-year mortality rates in adult dialysis patients with IE. Sensitivity analysis, subgroup analysis, and meta-regression were performed to explore potential sources of heterogeneity. Confidence of evidence was evaluated by the GRADE system. Thirteen studies were included. The pooled odds ratio of in-hospital mortality was 0.62 (95% confidence interval [CI]: 0.30-1.28, p = .17), with moderate heterogeneity (I2 = 62%, p < .01). Three studies reported 30-d mortality, and the pooled odds ratio for surgery compared with medical treatment was even lower (0.36; 95% CI: 0.22-0.61, p < .01), with low heterogeneity (I2 = 0%, p = .86). With studies on fewer than 30 patients excluded, the sensitivity analysis revealed a low odds ratio of in-hospital mortality for surgery versus medical treatment (0.52; 95% CI: 0.27-0.99, p = .047), with moderate heterogeneity (I2 = 63%, p < .01). Subgroup analysis revealed no significant differences between any two comparator subgroups. Based on a very low strength of evidence, compared with medical treatment, surgical treatment for IE in patients on dialysis is not associated with lower in-hospital mortality. When studies on fewer than 30 patients were excluded, surgical treatment was associated with better survival.

Association between different systemic therapies and the risk of tuberculosis in psoriasis patients: A population-based study.

BACKGROUND: Despite the evolution of biologic agents, the use of traditional systemic immunosuppressants still account for a considerable proportion of systemic anti-psoriasis therapy. The risk of tuberculosis among psoriasis patients receiving such conventional immunosuppressants is not clearly understood. METHODS AND MATERIALS: We used the retrospectively-collected data from the Taiwan National Health Insurance Research Database to perform this prospective cohort study. We included 94,585 adult patients with newly diagnosed psoriasis between January 1, 2001 and December 31, 2013. We documented the exposure of systemic anti-psoriasis therapies. The outcome is incident mycobacterium tuberculosis infection. RESULTS: During a mean 6.8 years follow-up, 703 (0.74%) incident tuberculosis was diagnosed and treated. The crude incidence of tuberculosis was 1.11 (95% confidence interval [CI] 1.03-1.19) events per 1000 person-years. The result demonstrated that MTX (Hazard ratio [HR] 2.16, 95% CI 1.47-3.16) and tacrolimus (HR 5.31, 95% CI 1.66-17.01) were significantly associated with increased risks of tuberculosis. Noticeably, azathioprine was a borderline significant risk factor of tacrolimus (HR 2.63, 95% 0.96-7.21, P = 0.059). The risk of TB in patients receiving adalimumab was twofold (HR 2.07) though not significant because of only one TB event was detected. The steroid was also associated with a dose-dependent increase of tuberculosis risk (HR 1.09, 95% CI 1.09-1.12, for every 1 mg of prednisolone equivalent dose per day). CONCLUSION: The study found that among systemic anti-psoriasis therapy, methotrexate, tacrolimus, azathioprine and steroid may be associated with an increased risk of tuberculosis.

Risk of herpes zoster in psoriasis patients receiving systemic therapies: a nationwide population-based cohort study.

The incidence of herpes zoster in psoriasis patients is higher than in the general population. However, the association between herpes zoster risk and different systemic therapies, especially biologic agents, remains controversial. This study investigated the association between herpes zoster risk and several systemic antipsoriasis therapies. This prospective open cohort study was conducted using retrospectively collected data from the Taiwan National Health Insurance Research Database. We included 92,374 patients with newly diagnosed psoriasis between January 1, 2001, and December 31, 2013. The exposure of interest was the "on-treatment" effect of systemic antipsoriasis therapies documented by each person-quarter. The outcome was the occurrence of newly diagnosed herpes zoster. During a mean follow-up of 6.8 years, 4834 (5.2%) patients were diagnosed with herpes zoster after the index date. Among the systemic antipsoriasis therapies, etanercept (hazard ratio [HR] 4.78, 95% confidence interval [CI] 1.51-15.17), adalimumab (HR 5.52, 95% CI 1.72-17.71), and methotrexate plus azathioprine (HR 4.17, 95% CI 1.78-9.82) were significantly associated with an increased risk of herpes zoster. By contrast, phototherapy (HR 0.76, 95% CI 0.60-0.96) and acitretin (HR 0.39, 95% CI 0.24-0.64) were associated with a reduced risk of herpes zoster. Overall, this study identified an association of both etanercept and adalimumab with an increased risk of herpes zoster among psoriasis patients. Acitretin and phototherapy were associated with a reduced risk.

Uremic pruritus and long-term morbidities in the dialysis population.

BACKGROUND: Uremic pruritus (UP) is a multifactorial problem that contributes to low quality of life in dialysis patients. The long-term influences of UP on dialysis patients are still poorly understood. This study aims to elucidate the contribution of UP to long-term outcomes. MATERIALS AND METHOD: We used the Taiwan National Health Insurance Research Database to conduct this study. Patients on chronic dialysis were included and divided into UP and non-UP groups according to the long-term prescription of antihistamine in the absence of other indications. The outcomes include infection-related hospitalization, catheter-related infection, major adverse cardiac and cerebrovascular events (MACCE) and parathyroidectomy. RESULTS: After propensity score matching, 14,760 patients with UP and 29,520 patients without UP were eligible for analysis. After a mean follow-up of 5 years, we found that infection-related hospitalization, MACCE, catheter-related infection, heart failure and parathyroidectomy were all slightly higher in the UP than non-UP group (hazard ratio: 1.18 [1.16-1.21], 1.05 [1.01-1.09], 1.16 [1.12-1.21], 1.08 [1.01-1.16] and 1.10 [1.01-1.20], respectively). Subgroup analysis revealed that the increased risk of adverse events by UP was generally more apparent in younger patients and patients who underwent peritoneal dialysis. CONCLUSION: UP may be significantly associated with an increased risk of long-term morbidities.

Subcutaneous Fungal Infection Caused by a Non-sporulating Strain of Corynespora cassiicola Successfully Treated with Terbinafine.

Corynespora cassiicola is a common plant pathogen, but C. cassiicola infection in human hosts is extremely rare. In this report, we present an 84-year-old male with long-term use of inhaled corticosteroids who developed a subcutaneous infection caused by C. cassiicola. The organism was isolated from both wound culture and biopsy specimen from the skin lesion. However, no microscopic diagnostic characters could be obtained because the isolates failed to sporulate on different culture media. Molecular diagnosis by amplification and sequencing of the internal transcribed spacer regions of ribosomal DNA was performed, and the sequences of the isolates were identical to those of C. cassiicola. The patient was treated successfully with oral terbinafine therapy for 12 weeks. In this report, we also review the epidemiology, clinical and therapeutic facets of cutaneous C. cassiicola infection.

Scleromyxedema and lichen myxedematosus: Is it associated with viral hepatitis?

Scleromyxedema (SM) was previously known to be associated with monoclonal gammopathy. The association of SM and its counterpart lichen myxedematosus (LM) with chronic hepatitis has rarely been reported. We retrospectively reviewed medical records and histopathological reports of consecutive patients who presented at our department with the diagnosis of SM or LM from January 2001 to September 2017. The patients' demographic details, cutaneous presentation, associated underlying diseases and hepatitic profile were studied and compared with previous published cases. In all, 28 patients were enrolled, including one SM, 19 LM and eight atypical LM. Of the patients, 50% (n = 14/28) had hepatitis. Of these, 21.4% (n = 6/28) had hepatitis C, 10.7% (n = 3/28) hepatitis B, 7.1% (n = 2/28) concurrent hepatitis B and C, whereas 10.7% (n = 3/28) had alcoholic liver disease. The prevalence of hepatitis C in our patients was 6.5-times higher than that of the general population (28.6% vs 4.4%) and the prevalence of hepatitis B was similar (17.9% vs 17.3%). Polyclonal gammopathy was found in 28.6% (n = 8/28) of the patients and monoclonal gammopathy was found in 7.1% (n = 2/28). The extent of clonality did not correlate with disease severity. Our study did not notice a significant association with monoclonal gammopathy but the prevalence of hepatitis C was found to increase 6.5-times in these patients compared with the general population. We recommend dermatologists to be aware of hepatitis investigations in such patients and future studies are warranted to understand the mechanism behind such association.

Risk of Hepatitis B Reactivation in Patients with Psoriasis on Ustekinumab.

BACKGROUND AND OBJECTIVES: Ustekinumab is used to treat moderate-to-severe psoriasis by blocking the interleukin-12/23 pathway, which is also essential against intracellular pathogens. Because there is a high prevalence of hepatitis B viral infection in Taiwan, the expected risk of reactivation is higher among ustekinumab-treated patients. We performed this study to investigate the risk of hepatitis reactivation. SUBJECTS AND METHODS: Patients with psoriasis treated with ustekinumab from October 2011 to June 2016 were enrolled in a prospective cohort study. All patients were tested for hepatitis B serology and serum viral DNA at baseline. For those positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibodies (anti-HBc) testing for HBV DNA was conducted at least annually. An increase of HBV DNA > 2 log scale or emergence of HBV DNA were defined as reactivation. The primary outcome of this study was HBV reactivation. RESULTS: Ninety-three psoriasis patients receiving ustekinumab were included. The average duration of treatment and follow-up was 24 ± 12 months. There were 39 patients classified as naïve to HBV or vaccinated, and none of these patients had HBV reactivation. Among the remaining 54 patients classified as inactive HBV carriers, resolved HBV infection, or isolated anti-HBc positivity, only 3 patients experienced virologic reactivation, and none had liver failure. CONCLUSION: The study outcomes indicate that ustekinumab could be safe for psoriasis patients since none developed persistent hepatitis or acute liver failure during therapy. However, the re-appearance of plasma HBV DNA requires appropriate monitoring of HBV viral load during ustekinumab treatment.
