Linear IgA bullous dermatosis (LABD) is a rare acquired autoimmune chronic vesiculobullous dermatosis affecting primarily young children and older adults. We report a 17-year-old Chinese boy with a 2-month history of intense itching erythema or tense vesicles on healthy skin or on an erythematous base, with parts of lesions arising a characteristic "cluster of jewels" pattern. With the characteristics of vesicles or blisters on the skin, subepidermal blisters with neutrophilic infiltrate on histology, and linear IgA deposits on the basement membrane zone and absence of other immunoglobulins on direct immunofluorescence, LABD was dignosized. Sulfapyridine has also been reported as one of the best options of systemic therapy for LABD. Our patient successfully treated with only oral sulfasalazine (alternative medicine of sulfasalazine), which is safe and effective.

Hailey-Hailey disease (HHD), or chronic benign familial pemphigus, is a rare inherited acantholytic dermatosis, characterized by chronic, recurrent vesicles, erosions, and maceration in intertriginous sites. We present a case of a male patient with longstanding HHD who presented with an acute exacerbation characterized by the worsening of pre-existing lesions but also with the appearance of new large, tense bullae on an erythematous base in the areas of the groin (i.e., inguinal region), trunk, and arms, associated with intense pruritus. Blood work revealed eosinophilia. Histopathology and direct immunofluorescence were compatible with the diagnosis of bullous pemphigoid (BP). Indirect immunofluorescence showed positivity for autoantibodies to BP antigen 180. We started oral methylprednisolone, oral antihistamines, and local care with potassium permanganate baths, a potent corticosteroid, and fusidic acid, with resulting improvement of the lesions. The case was further complicated by the occurrence of eczema herpeticum, which was successfully treated with acyclovir. At the time of discharge from the hospital, the patient was medicated with a low dose of oral steroid and oral doxycycline. During a later examination, the lesions had totally disappeared, but the skin had some residual hyperpigmented patches and excoriated papules. This case was a diagnostic challenge due to the simultaneous occurrence of three distinct bullous diseases with different etiopathogeneses. To our knowledge, there are no other reports of the coexistence of HHD and BP in the literature.

Kratom, or Mitragyna speciosa Korth., is a tropical plant prevalent in Southeast Asia, and it is utilized as a traditional remedy for symptomatic relief of various illnesses. It has been labeled as an atypical opioid with significant narcotic-like properties, capable of inducing kratom dependence among those who misuse or abuse it. The prevalence of kratom use has drastically increased worldwide, raising concerns among healthcare providers, particularly regarding the availability of efficacious treatment options for kratom dependence. This manuscript provides a comprehensive narrative review of literature focusing on the psychoactive alkaloids of kratom, the possible neurobiological and pathophysiological models underlying the occurrence of kratom dependence, and the clinical presentations and effective treatment options available for kratom dependence. The psychoactive alkaloids of kratom, such as mitragynine (MG) and 7-hydroxymitragynine (7-HMG), act as partial mu opioid agonists and induce kratom dependence. As a result, regular kratom use leads to withdrawal symptoms on abstinence, along with craving, tolerance, and cross-tolerance to morphine. The psychological withdrawal symptoms reported include depressed mood, anxiety, restlessness, irritability, and feeling tense, while the physical withdrawal symptoms are myalgia and body ache, joint pain, lacrimation, running nose, yawning, insomnia, diarrhea, feverish sensation, loss of appetite, tremors, itching over the body, loss of concentration, and chills. Neonatal withdrawal symptoms, such as oral intolerance, restlessness, irritability, and vomiting, are also reported in newborns of women who are on regular kratom use. Sublingual buprenorphine-naloxone (Suboxone) is reported as a promising treatment for detoxification and maintenance replacement therapy for kratom-dependent users. Alternative treatments for in-patient detoxification include intravenous clonidine and a combination of oral dihydrocodeine and lofexidine. We conclude by adding a note on the research gap concerning kratom dependence, which future studies should focus on.

Bullous pemphigoid is the most frequent autoimmune bullous disease and mainly affects elderly individuals. Increase in incidence rates in the past decades has been attributed to population aging, drug-induced cases and improvement in the diagnosis of the nonbullous presentations of the disease. A dysregulated T cell immune response and synthesis of IgG and IgE autoantibodies against hemidesmosomal proteins (BP180 and BP230) lead to neutrophil chemotaxis and degradation of the basement membrane zone. Bullous pemphigoid classically manifests with tense blisters over urticarial plaques on the trunk and extremities accompanied by intense pruritus. Mucosal involvement is rarely reported. Diagnosis relies on (1) the histopathological evaluation demonstrating eosinophilic spongiosis or a subepidermal detachment with eosinophils; (2) the detection of IgG and/or C3 deposition at the basement membrane zone using direct or indirect immunofluorescence assays; and (3) quantification of circulating autoantibodies against BP180 and/or BP230 using ELISA. Bullous pemphigoid is often associated with multiple comorbidities in elderly individuals, especially neurological disorders and increased thrombotic risk, reaching a 1-year mortality rate of 23%. Treatment has to be tailored according to the patient's clinical conditions and disease severity. High potency topical steroids and systemic steroids are the current mainstay of therapy. Recent randomized controlled studies have demonstrated the benefit and safety of adjuvant treatment with doxycycline, dapsone and immunosuppressants aiming a reduction in the cumulative steroid dose and mortality.
