Complex ADHD Challenging Case: Managing Co-Occurring Attention-Deficit Hyperactivity Disorder and Congenital Heart Disease with a Limited Medication Formulary: A Case from Mexico.
DL is an 8-year-old Mexican boy with a posterior atrial septal defect and partial anomalous pulmonary venous return of the right lower pulmonary vein with resultant right heart dilation with normal right ventricular systolic and diastolic function and no arrhythmias. Surgical repair was deferred, and DL's condition was being medically managed with furosemide 0.5 mg/kg BID and spironolactone 0.5 mg/kg BID.DL presents for developmental assessment due to poor performance in school following a lifting of COVID-19 pandemic restrictions and return to in-person classes. He has been attending full-time classes for 3 months without improvements in math, reading, and writing skills. Current attentional concerns at school include an inability to complete tasks without getting distracted by minimal stimuli and highly impulsive behavior.At the first assessment, DL was performing below grade expectations (e.g., reading by syllable without text comprehension, demonstrating preoperational addition and subtraction skills, inability to take dictation)-all of which was viewed as negatively impacted by attentional deficits. DL met DSM-5 criteria for ADHD, predominantly inattentive type. He was started on 10-mg immediate-release methylphenidate PO at 8 am with breakfast and a second dose of 10-mg immediate-release methylphenidate PO 4 hours after the first dose.After a month, at the first follow-up consultation, improvement in attention span, impulsivity, and school performance were observed, including reading skills and math proficiency. However, DL's mother raised concerns about circumoral cyanosis and acrocyanosis in the fingers of both hands after playing outside. These signs were not previously observed. During physical examination at the same visit, heart rate, blood pressure, and oximetry were within baseline ranges and his cardiac examination was unchanged. DL's dosage of methylphenidate was lowered to 10-mg immediate-release methylphenidate PO QD in the mornings with breakfast (8 am).DL did not return to clinic for another 2 months, having discontinued the medication after 2 months of treatment given financial limitations. His mother reported that DL's exertional circumoral cyanosis and acrocyanosis resolved while he was off medication. However, she observed an increase in inattentive symptoms and impulsivity and decline in his academic skills. She asked if our team was able continue the treatment despite the drug side effects, since she believed the benefits outweighed the disadvantages.Given these concerns, the team requested an updated cardiology assessment. The Cardiologist recommended discontinuation of methylphenidate and recommended follow-up with cardiothoracic surgery for reassessment of the surgical timeline.Given the limited treatment options in Mexico, what would you do next as the treating developmental-behavioral clinician…?

Review
Raynaud's syndrome is a common finding in many autoimmune conditions. Accurately diagnosing Raynaud's, and differentiating it from mimicking conditions, is imperative in rheumatologic diseases. Raynaud's syndrome and Raynaud's mimickers, especially painful Raynaud's mimickers, can prove a diagnostic challenge for the practicing rheumatologist. Painful Raynaud's mimickers can lead to increased patient stress and unnecessary medical work up; Healthcare providers need to be aware of Raynaud's mimickers when evaluating patient concerns of skin color changes and pain. The present narrative review aims to highlight Raynaud's syndrome, important painful mimickers that may be seen, diagnosis, and updated management recommendations.

Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks. The average morbidity from Lyme borreliosis in the Republic of Croatia is 6.51 infected per 100,000 inhabitants. There can be no Lyme borreliosis without ticks infected by Borrelia burgdorferi (1,2). In Europe, Lyme borreliosis (LB) is caused by the Borrelia burgdorferi sensu lato complex genotype. There are three skin manifestations of LB: erythema migrans (EM), borrelial lymphocytoma (BL), and acrodermatitis chronica atrophicans (ACA) (3,4). Herein we describe a female patient with a diagnosis of Lyme disease based on the non-specific clinical picture and laboratory diagnostics, in whom successful treatment led to complete regression of all skin manifestations. The patient was a 58-year-old woman with no previous history of severe illness. Notably, the patient history showed that, eight months prior to presenting for the dermatological exam, the patient had observed the appearance of edema and demarcated macular exanthema around both ankles and subsequently on the dorsum of the right hand, which spread to the left hand and with gradual spread to both lower legs and the lower extremities, with more pronounced changes on the left leg. The initial dermatological examination found pronounced skin changes on both legs, especially the left leg, with erythematous changes in the form of figurate erythema forming confluences up to the size of a smaller palm; the skin of the left leg was partially mottled with normal turgor and elasticity (Figure 1a and Figure 1b). Inguinal lymph nodes were enlarged and painless on palpation. Changes were minimal and discrete on the right leg and were absent on the torso, upper extremities, and skin. Subjectively, there was no itching, burning, or tingling sensation in the affected areas of the skin. The patient subjectively reported feeling well. Family history showed that the patient's father had died from prostate cancer and that the mother had died from melanoma. Laboratory findings were as follows: hematological, biochemical, and immunological parameters were normal. Venous and arterial ultrasound of both legs was normal, with the presence of reactively enlarged left inguinal lymph nodes. Lyme disease was suspected based on the clinical picture, with a differential diagnosis of possible livedo reticularis. A biopsy of the skin changes was also performed, with the results showing that the histological picture in the examined material could be compatible with the provisional clinical diagnosis of livedo reticularis. IgM and IgG specific for Borrelia burgdorferi was also performed: IgG was borderline, whereas IgM was positive at 218 U/mL. Over the next 3 weeks, Amoxil 500 mg thrice daily was introduced to the treatment. After completion of the treatment, there was a gradual regression of all skin changes without the appearance of new lesions (Figure 2a and Figure 2b) (Figure 3a and Figure 3b). Patient follow-up over the next year did not find any recurrence of similar skin changes. Herein we have described the case of a patient with atypical skin changes in which the presence of antibodies for Borrelia burgdorferi was demonstrated, in which regression of all skin manifestations was achieved after diagnosis and adequate antibiotic treatment. Lyme disease has a wide spectrum of clinical manifestations that can generally be observed in three stages: the early localized stage, the early disseminated stage, and the late stage of the disease. However, it is also possible for the different stages to overlap and even for the late stage to manifest without any signs and symptoms of the earlier stages. Early localized stage. Characterized by skin changes - erythema migrans (EM) - usually manifests within a month of the tick bite (usually 7-14 days after the bite) (Figure 4 and Figure 5). EM manifests in approximately 80% of patients, but only 25% of patients can recall the tick bite. The skin changes are usually localized in the axilla, the groin, the cubital area, or around the waist. The changes are generally not painful, but can itch or be warm to the touch. They gradually spread over days or weeks and can grow to a radius of up to 20 cm. Initially, the coloration can be uniform for several days, after which the redness disappears around a central zone (4-6). Multiple skin changes are a sign of spirochetemia and not the result of multiple tick bites. Due to timely antimicrobial treatment, multiple skin changes are much rarer today. In the initial days or weeks after infection, patients with early, localized, or disseminated Lyme disease often present with non-specific signs and symptoms resembling a viral infection: fatigue, headache, loss of appetite, joint pain, and regional lymphadenopathy. Fever can be present in approximately 20% of patients. Laboratory findings in this phase are non-specific. Erythrocyte sedimentation can be slightly increased, leukocyte counts are mostly normal, and anemia and thrombocytopenia are present only rarely (7,8). Early disseminated stage. This stage is marked by numerous EM lesions (that generally appear days or weeks after the infection) and/or neurological and/or cardiac manifestations (occurring weeks or months after infection). Some of these patients have no data on the presence of early localized Lyme disease. The most common triad of neurological manifestations are meningitis, neuropathy (usually of the facial nerve) and motor or sensory radiculopathy (Bannwarth syndrome). All these manifestations can appear individually. Cranial nerve neuropathies can often be bilateral. Late-stage Lyme disease. Characterized by intermittent or permanent arthritis in one joint or several large joints, most commonly the knees, and/or more rarely by neurological symptoms such as discrete encephalopathy or polyneuropathy. Late-stage Lyme disease can develop several years after primary infection, and arthritis can be the first manifestation of the disease, with the early localized and early disseminated stages not manifesting at all. In Europe, patients with late-stage Lyme disease can present with chronic skin changes (acrodermatitis chronica atrophicans), which is not observed in the USA. It is caused by B. afzelii and is typically localized to the extensor surfaces of the hands and feet. It is most common in women >40 years of age but can also present in younger populations. However, due to early antimicrobial treatment of the earlier stages of the disease, late-stage manifestations are rare (9). The discovery of the etiology of this disease showed that some well-known clinical entities were also a manifestation of Borrelia infection. The etiology of other dermatologic diseases was thus determined, such as lymphocytoma (or lymphadenosis cutis benigna), which was recognized as an entity as early as 1884, as well as acrodermatitis chronica atrophicans, described in 1888, erythema chronicum migrans (Afzelius-Lipschütz), and the neurological disease called Bannwarth syndrome, the symptoms of which were described as early as 1922 (10,11). LB and all its dermatological manifestations occur in almost all European countries, predominantly in the central part of the continent. The annual incidence is between 9.4 cases per 100,000 inhabitants in France to 120 cases per 100,000 inhabitants in northeastern Poland, 130 cases per 100,000 inhabitants in Austria, and 155 cases per 100,000 inhabitants in Slovenia (12). The total prevalence of ACA in all European patients with LB is 1-10%, depending on the region. For example, BL and ACA comprise 0.3% of LB cases in Bulgaria. In Norway, ACA comprises 5% of all clinical LB cases, and in northern Italy that number is 2.5%. Establishing a diagnosis of ACA is much more difficult than diagnosing EM or benign lymphocytoma (BL) because the clinical manifestations of ACA can vary. Acrodermatitis chronica atrophicans is probably the most common late and chronic manifestation of LB that can be observed in European patients. The skin changes in our patient were fairly non-specific, based on descriptions from the literature, but positivity for IgM antibodies was important for establishing the diagnosis, along with the very good response to antibiotics regarding regression of skin changes as well as the histological analysis that, according to the pathohistological diagnosis, indicated livedo reticularis, which is in turn also described in the literature as a possible form of ACA depending on the stage of the disease. Skin changes on the lower extremities are often incorrectly interpreted as vascular insufficiency, e.g. chronic venous insufficiency, superficial thrombophlebitis, hypostatic eczema, obliterative arterial disease, acrocyanosis, livedo reticularis, or lymphoedema, but they can also be the result of ACA, as in our case (13-15). In cases such as the one we have described, clinical manifestations of Lyme disease can very often vary and differ greatly from the typical clinical picture. This is demonstrated by our case, which also shows that LB and its idiosyncratic manifestations can lead physicians astray in a condition where failing to establish a timely diagnosis can be fatal for the patient. This case report also serves as a reminder that Lyme disease should be considered whenever atypical skin changes are encountered. Given that ACA is a disease in the late stage of Lyme disease and that the changes in our patient were noticed at the very beginning, the disease did not develop to the later stage.

Autoimmune hemolytic anemia (AIHA) is a rare autoantibody-mediated disease. For steroid and/or rituximab-refractory AIHA, there is no consensus on optimal treatment. Daratumumab, a monoclonal antibody targeting CD38, could be beneficial by suppression of CD38+ plasma cells and thus autoantibody secretion. In addition, because CD38 is also expressed by activated T cells, daratumumab may also act via immunomodulatory effects. We evaluated the efficacy and safety of daratumumab monotherapy in an international retrospective study including 19 adult patients with heavily pretreated refractory AIHA. In warm AIHA (wAIHA, n = 12), overall response was 50% with a median response duration of 5.5 months (range, 2-12), including ongoing response in 2 patients after 6 and 12 months. Of 6 nonresponders, 4 had Evans syndrome. In cold AIHA (cAIHA, n = 7) overall hemoglobin (Hb) response was 57%, with ongoing response in 3 of 7 patients. One additional patient with nonanemic cAIHA was treated for severe acrocyanosis and reached a clinical acrocyanosis response as well as a Hb increase. Of 6 patients with cAIHA with acrocyanosis, 4 had improved symptoms after daratumumab treatment. In 2 patients with wAIHA treated with daratumumab, in whom we prospectively collected blood samples, we found complete CD38+ T-cell depletion after daratumumab, as well as altered T-cell subset differentiation and a severely diminished capacity for cell activation and proliferation. Reappearance of CD38+ T cells coincided with disease relapse in 1 patient. In conclusion, our data show that daratumumab therapy may be a treatment option for refractory AIHA. The observed immunomodulatory effects that may contribute to the clinical response deserve further exploration.

COVID-19 is known to cause various cutaneous lesions, including acro-ischemic lesions (AIL), which are associated with poor prognosis. Anticoagulant therapy has shown positive responses in AIL patients. However, in this case study, we present a fatal AIL case despite anticoagulant therapy. We propose different treatment approaches based on the limited current data on acro-ischemia pathogenesis related to SARS-CoV-2. The clinical case involved a 59-year-old male with severe COVID-19 symptoms, including acrocyanosis and right hemiparesis. Despite receiving anticoagulant therapy, the patient's condition worsened, leading to necrosis in the left foot. The discussion focuses on the high-risk nature of AIL, the potential link between angiotensin-converting enzyme 2 (ACE2) receptors and vasculitis or thromboembolic manifestations, and the role of immune clots in AIL pathogenesis. Behçet syndrome is referenced as a model of inflammation-induced thrombosis, guiding the suggestion for immunosuppressant-based treatment in addition to anticoagulants. Additionally, three substances, N-acetyl cysteine, sulodexide, and hydroxychloroquine, are proposed.

INTRODUCTION AND IMPORTANCE
Essential thrombocythemia (ET) is a rare chronic myeloproliferative hematologic disorder, leading to an elevated platelet count. Two-thirds of patients are asymptomatic during their lifetime, while others may experience symptoms like redness, congestion, and erythromelalgia after long symptom-free intervals.
CASE PRESENTATION
The authors present a rare instance of a 55-year-old female who, despite receiving aspirin and losartan treatment, eventually developed digital gangrene. In further work-ups, she had an elevated platelet count and a positive JAK 2 mutation. Her platelet count was reduced throughout treatment with aspirin, hydroxyurea, and heparin, which was followed by the necrotic tip of her index finger being surgically debrided.
CLINICAL DISCUSSION
Significant symptoms, such as severe acrocyanosis and even peripheral gangrene, can be treated with a single dose of aspirin. Daily aspirin consumption withstanding, this case developed the severe form of ET. In addition, while thrombocytosis predisposes patients to thrombotic complications in theory, there is little evidence to support a correlation between absolute platelet count and thrombosis.
CONCLUSION
The initial symptom of ET could be such severe and uncommon that may develop arterial acral thrombosis despite previous daily low-dose aspirin consumption.

Puffy hand syndrome occurs in addicts who have injected drugs either intravenously, intradermally, or subcutaneously. It usually presents as bilateral reversible pitting edema of the hands; less frequently, it occurs unilaterally. The forearms and arms may also be affected. The onset of puffy hand syndrome can occur while the patient is still injecting drugs; however, it can initially appear several years after injection of the drug has been discontinued. Infection with hepatitis C is a common comorbidity. A 47-year-old man is described who had a 20-year history of injecting methylamphetamine only into his non-dominant left arm, forearm, and hand and experienced his second episode of unilateral puffy hand syndrome four years after discontinuing injecting the drug and three years after his initial episode; he also had hepatitis C infection. He presented with erythema and pitting edema of his left hand and forearm. Cellulitis was initially suspected, and he was admitted to the hospital for intravenous antibiotics; all cultures were negative for pathogens. The erythema and swelling resolved after five days of therapy. Puffy hand syndrome has been associated with various drugs; it has also been observed to occur in women during pregnancy and occasionally associated with acrocyanosis. The diagnosis is often not originally entertained by the clinician; the condition is often initially treated empirically as an infection. Serologic evaluation is typically negative for rheumatologic diseases, such as systemic lupus erythematosus and scleroderma, and cultures of the skin and blood are usually negative for pathogens. Radiologic assessment (such as roentgenograms, ultrasound to rule out venous thrombosis, computed tomography, magnetic resonance imaging, venogram, and lymphangiogram) may be performed, to exclude other conditions. Skin biopsy of the affected edematous hand occasionally demonstrates granulomatous inflammation and foreign bodies (suggestive of starch or injection additives) in the dermis. The edema for some of the patients with puffy hand syndrome was successfully treated with daily bandaging with compression stockings. The pathogenesis of puffy hand syndrome is considered to be multifactorial: damage to the veins, injury to the lymphatic system, and direct toxicity of the injectable drugs to the vascular structures.
