Dermatological diseases presented before COVID‐19: Are patients with psoriasis and superficial fungal infections more vulnerable to the COVID‐19?

Recent studies have focused on the comorbid conditions of the COVID‐19. According to the current studies, numerous diseases including lung disease, cardiovascular disease and immunosuppression appear to be at higher risk for severe forms of the COVID‐19. To date, there are no data in the literature on the comorbid dermatologic diseases and COVID‐19. We tried to analyze the previous dermatological comorbidity of 93 patients with COVID‐19 (51 males, 42 females) who presented to the dermatology outpatient clinics for the last 3 years. The most common dermatologic diseases in patients with COVID‐19 who have dermatologic diseases for the last 3 years were superficial fungal infections (24, 25.8%), seborrheic dermatitis (11, 11.8%), actinic keratosis (10, 10.8%), psoriasis (6, 6.5%), and eczema (6, 6.5%), respectively. In addition, the number of COVID‐19 patients who presented to dermatology in the last 3 months was 17 (11 men, 6 women). The median age of these patients was 58 (minimum 18, maximum 80) years, and the most common dermatologic diseases before diagnosed COVID‐19 were superficial fungal infections (5, 25%), psoriasis (4, 20%), and viral skin diseases (3, 15%). The possible similarity between cutaneous and mucosal immunity and immunosuppression suggests that patients with some dermatologic diseases especially superficial fungal infections and psoriasis may be more vulnerable to the COVID‐19.     

Efficacy of dry needling in patients with myofascial temporomandibular disorders related to the masseter muscle

ABSTRACT

Objective

This randomized, single-center clinical trial aimed to compare the efficacy of superficial dry needling (SDN) and deep dry needling (DDN) in patients with myofascial temporomandibular disorder (MTMD) related to the masseter muscle.Methods: Forty patients showing MTMD with trigger points in the masseter muscle were randomly assigned to groups. Dry needling of the masseter muscle was performed once per week for three weeks. Pressure pain threshold (PPT) measurements, visual analog scale scores, and maximal jaw opening were assessed.Results: Both patient groups showed significant pain reduction, but the SDN group showed significantly better pain reduction. The PPT measurements obtained in the follow-up examinations at three and six weeks were significantly better than the values in SDN and DDN groups.Discussion: SDN showed better pain-reduction efficacy in patients with MTMD. Further research with a larger size sample and a longer follow-up period will help elucidate the benefits of SDN.     

PILOMATRICOMA IN CHILDREN: A Frequently Misdiagnosed Superficial Tumor

Pilomatricomas are the most common superficial tumors in children, but they are frequently misdiagnosed preoperatively. There are some characteristic features of pilomatricomas that can help clinicians differentiate it from other tumors. The authors report 3 children with head and neck pilomatricomas, one with multiple tumors. They emphasize some clinical features that may help in differential diagnosis to avoid unnecessary investigations before surgical removal.     

Successful kidney transplantation after coccidioidal meningitis

S.L. Kokseng, J.E. Blair. Successful kidney transplantation after coccidioidal meningitis
Transpl Infect Dis 2011: 13: 285–289. All rights reserved Abstract: Coccidioidomycosis is a fungal infection primarily found in residents or visitors to geographic areas where Coccidioides species are endemic, including the southwestern United States, northwestern Mexico, and certain areas of Central and South America. The infection rarely disseminates, but certain populations are at higher risk of dissemination. One population at high risk of disseminated disease is solid organ transplant recipients. At our transplant center in Arizona, patients with proven coccidioidal infection before transplantation undergo thorough counseling about the risks of dissemination and possible death from coccidioidomycosis subsequent to the use of immunosuppressive medications after transplantation. Currently, patients with coccidioidal infection before transplantation are maintained on lifelong infection suppression with triazole therapy. We present the first successful case of a kidney transplant in a patient after treatment for coccidioidal meningitis without post‐transplant reactivation of the coccidioidal infection.     

Superficial fibular nerve variations of fascial piercing: A meta‐analysis and clinical consideration

The superficial fibular (peroneal) nerve (SFN) is one of the successive branches of the common fibular (peroneal) nerve and goes on to bifurcate into the medial dorsal cutaneous (MDN) and intermediate dorsal cutaneous (IDN) nerves. The SFN is a main contributor to sensory innervation of the foot and lower leg. It varies widely in its penetrance of the deep (crural) fascia, and differences in its subsequent course can result in iatrogenic injuries. Articles on the prevalence of this anatomical variation were identified by a comprehensive database search. The data collected were extracted and pooled into a meta‐analysis. A total of 14 articles (n = 665 lower limbs) were included on the meta‐analysis of SFN variations in fascial piercing. The normal Type 1 variation, where the SFN pierces the deep fascia as a single entity and later bifurcates into the MDN and IDN, had a pooled prevalence of 82.7% (95%CI: 74.0–89.4). The Type 2 variant, where the SFN bifurcates early and then pierces the fascial layer separately as the MDN and IDN, had a pooled prevalence of 15.6% (95%CI: 8.9–23.6). Type 3, when the SFN penetrates the deep fascia and courses similar to the MDN with absent IDN was noted in 1.8% (95%CI: 0.0–4.9) of cases. A substantial portion of the population has a pattern of SFN piercing that deviates from the normal Type 1 anatomy. It is recommended that possible SFN variants in patients should be addressed thoroughly to help prevent iatrogenic injuries and postoperative complications. Clin.

Cutaneous presentation of disseminated histoplasmosis as a solitary peri‐anal ulcer. Case report and discussion

Disseminated histoplasmosis has a diverse and non‐specific range of clinical signs and symptoms. In a significant minority of patients, cutaneous lesions are apparent at the time of initial presentation, affording an opportunity to establish the diagnosis from a skin biopsy. The most frequently reported clinical scenario in immunocompromised patients with cutaneous involvement is that of multiple papulo‐nodular lesions on the face, trunk or extremities. The following report features an immunocompetent patient who presented with a solitary ulcerated plaque on the buttocks close to the anal verge. This case presentation underscores the broad spectrum of clinical presentations as well as the potential for diagnostic confusion with protozoa such as Leishmania or Trypanosoma species during histopathologic examination if special stains for fungal organisms are not performed.
