“Pseudo” Nomenclature in Dermatology: What's in a Name?

In the bewildering array of scientific nomenclature in the medical field, it is important to use correct terminology, know their aberrations and the reason behind a specific terminology. This paper is an attempt towards compiling all the pseudo-nomenclatures coined in dermatology, in order to make it easier to retain and recollect these pseudo names, signs, morphology, diseases, and conditions. It is also imperative to know the true entities that these pseudo names masquerade as, so as to understand the explanation for assigning the term ‘pseudo’ to these conditions. A total of 52 pseudo-terms have been compiled here in reference to dermatology. Most of these pseudo-nomenclatures were coined due to some clinical or histopathological resemblance to the true conditions, while some were premature conclusions drawn from a flawed understanding of the basic nature of the condition. Clear understanding of each of these terms and the explanation behind them being pseudo will enable a dermatologist to avoid misdiagnosis and needless confusion.     

Cutaneous Manifestations of Acquired Immunodeficiency Syndrome in Children

Cutaneous disorders are among the most common manifestations of HIV infection in both children and adults. Because of the obvious visibility of the integument, these lesions are often the presenting manifestation of HIV-related disease. The cutaneous afflictions are frequently related to the sequelae of impaired immunity and include opportunistic infections and neoplasms as well as dramatic exacerbations and/or the development of rapidly progressive and severe manifestations in pre-existing, normally benign dermatoses. In many cases of AIDS, iatrogenic cutaneous disorders associated with toxic or allergic drug reactions are seen. With the increasing incidence of pediatric HIV infection and with therapeutic prolongation of survival, certain cutaneous manifestations (especially drug reactions) are likely to become more common. Kaposi sarcoma and other neoplasms may be recognized with increased frequency in HIV-infected children. New or previously unrecognized cutaneous manifestations of pediatric AIDS are likely to emerge. Familiarity with the various dermatologic presentations of pediatric AIDS can result in the earlier diagnosis and treatment of the disease and, hopefully, the prolongation of the patient's life.     

Paget von Schroetter Syndrome Secondary to Exotic Dancing: A Case Study

Axillary vein thrombosis, or Paget von Schroetter syndrome, is a rare clinical condition. It is associated with several thrombogenic states and numerous sporting activities involving excessive use of the arm. We report one such case associated with exotic dancing. In societies where dancing involves excessive arm movement, the physician must be aware of this condition to permit early diagnosis and effective treatment.     

A Critical Review of Alcohol Administration Guidelines in Laboratory Medication Screening Research: Is It Time to Include Treatment Seekers?

Human laboratory studies play an important role in alcohol use disorder (AUD) medication development. Medications that are found to be safe and effective during human laboratory screening will then move to more expensive clinical trials in patient populations. Given the gatekeeping role of human laboratory studies in the medication development pipeline, it is critical that these studies accurately forecast how pharmacotherapies will perform under true-to-life clinical conditions. On the other hand, the design of these studies also must adhere to ethical guidelines: certain aspects of clinical reality cannot be incorporated into screening studies because doing so might place the participant at risk for harm or breach other ethical guidelines. Conventions exist that guide the resolution of these conflicting ideals. This article considers the practice of recruiting non–treatment-seeking heavy drinkers to participate in laboratory screening studies. By convention, volunteers are excluded from laboratory screening studies that involve alcohol administration if they are deemed “treatment seeking,” meaning that they recently stopped drinking or are motivated to do so. Although this common practice may reduce risk to participants, findings may not accurately predict medication effects on treatment seekers. Indeed, there is empirical evidence that treatment seekers differ from nontreatment seekers in their responses to medications (Neuropsychopharmacology 2017a; 42: 1776; Am J Drug Alcohol Abuse 2017b; 43: 703; J Psychiatr Res 2006; 40: 383). Here, we argue for the importance of recruiting treatment seekers for this research due to their qualitative difference from nontreatment seekers. We argue that these individuals should be the default population in human laboratory medication screening studies. We conclude by discussing 2 case examples of medication experiments led by our research groups that involved administering medications to treatment seekers.     

De novo development of antibodies to kidney‐associated self‐antigens angiotensin II receptor type I,collagen IV,and fibronectin occurs at early time points after kidney transplantation in children

Chronic rejection is the leading cause of graft loss following pediatric kidney transplantation. Our group and others have demonstrated an association between the development of Abs to self‐antigens and chronic rejection following adult lung and heart transplantation. The goal of this study was to determine whether Abs to kidney‐associated self‐antigens develop following pediatric renal transplantation. We investigated post‐transplant development of Abs to kidney‐associated self‐antigens angiotensin II receptor type I, Fn, and collagen IV in a pediatric cohort. Using ELISA, we measured Abs to kidney‐associated self‐antigens in serum. Our cohort included 29 subjects with samples collected pretransplant and for 12 months post‐transplant. No samples had Abs to kidney‐associated self‐antigen pretransplant. In contrast, 50% (10/20) of subjects developed Abs to one or more kidney‐associated self‐antigen post‐transplantation. The median time to antibody appearance and duration of persistence were 103 and 61 days, respectively. Development of Abs did not correlate with graft function. Half of subjects developed Abs to kidney‐associated self‐antigens angiotensin II receptor type I, Fn, or collagen IV in the first year after kidney transplantation—a higher rate of early antibody development than expected. In this small study, Abs did not correlate with worse clinical outcomes.     

First living‐related liver transplant to cure factor VII deficiency

Congenital factor VII deficiency is an autosomal recessive serious disorder of blood coagulation with wide genotypic and phenotypic variations. The clinical presentation can vary from asymptomatic patients to patients with major bleedings in severe deficiency (factor VII <1%). Investigations show prolonged PT and low factor VII. Treatment modalities include FFP and repeated recombinant factor VII infusions. We hereby report the first successful LRLT for factor VII deficiency in an infant, the first‐ever youngest baby reported worldwide. A six‐month‐old male child presented with easy bruisability, ecchymotic patches, hematuria, and convulsions. CT of the head showed subdural hemorrhage, which was treated conservatively. He had markedly increased PT (120 s) with normal platelets, and aPTT with factor VII level <1%. Despite the treatment by rFVIIa administration weekly, which was very expensive, he still had repeated life‐threatening bleeding episodes. LRLT was performed with mother as the donor, whose factor VII level was 57%. A factor VII infusion plan for pre‐, intra‐ and postoperative periods was formulated and TEG followed. Postoperatively, his factor VII started increasing from third day and was 38% on 24th day with PT <14 s. He had uneventful intraoperative and postoperative courses. LT is a safe and definite cure for factor VII deficiency.
