Frequency of Thyroid Microcarcinoma in Patients Who Underwent Total Thyroidectomy with Benign Indication-A 5-Year Retrospective Review.

Background and Objectives: Incidental thyroid cancers (ITCs) are often microcarcinomas. The most frequent histologic type is a papillary microcarcinoma. Papillary thyroid microcarcinomas are defined as papillary thyroid tumours measuring less than 10 mm at their greatest diameter. They are clinically occult and frequently diagnosed incidentally in histopathology reports after a thyroidectomy. The aim of this study is to evaluate the rate of papillary thyroid microcarcinomas (PTMC) in patients who were thyroidectomised with indications of benign disease. Materials and Methods: We retrospectively evaluated the histological incidence of PTMC in 431 consecutive patients who, in a 5 year period, underwent a thyroidectomy with benign indications. Patients with benign histology and with known or suspected malignancy were excluded. Results: Histopathology reports from 540 patients who underwent a total thyroidectomy in our department between 2016 and 2021 were reviewed. A total of 431 patients were thyroidectomised for presumed benign thyroid disease. A total of 395 patients had confirmed benign thyroid disease in the final histopathology, while 36 patients had incidental malignant lesions (33 PTMC-7.67%, one multifocal PTC without microcarcinomas-0.23%, two follicular thyroid carcinoma-0.46%). Out of the PTMC patients, 29 were female and four were male (7.2:1 female-male ratio). The mean age was 54.2 years old. A total of 24 out of 33 patients had multifocal lesions, 11 of which co-existed with macro PTC. Nine patients had unifocal lesions. A total of 21 of these patients were initially operated on for multinodular goitre (64%), while 13 were operated on for Hashimoto/Lymphocytic thyroiditis (36%). Conclusions: PTMC-often multifocal-is not an uncommon, incidental finding after thyroidectomy for benign thyroid lesions (7.67% in our series) and often co-exists with other incidental malignant lesions (8.35% in our series). The possibility of an underlying papillary microcarcinoma should be taken into account in the management of patients with benign-especially nodular-thyroid disease, and total thyroidectomy should be considered.

Pharmaceutical Management of Secondary Hyperparathyroidism and the Role of Surgery: A 5-Year Retrospective Study.

Background and Objectives: Secondary hyperparathyroidism (SHPT) poses a common condition among patients with chronic kidney disease (CKD) due to the chronic stimulation of the parathyroid glands as a result of persistently low calcium levels. As a first option for medical treatment, vitamin D receptor analogs (VDRAs) and calcimimetic agents are generally used. Apart from cinacalcet, which is orally taken, in recent years, another calcimimetic agent, etelcalcetide, is being administered intravenously during dialysis. Materials and Methods: In a 5-year retrospective study between 2018 and 2023, 52 patients undergoing dialysis were studied. The aim of this study is to highlight the possible effects and/or benefits that intravenously administered calcimimetic agents have on CKD patients. A total of 34 patients (65.4%) received cinacalcet and etelcalcetide while parathormone (PTH) and calcium serum levels were monitored on a monthly basis. Results: A total of 29 out of 33 patients (87.9%) that received treatment with etelcalcetide showed a significant decrease in PTH levels, which rose up to 57% compared to the initial values. None of the included patients needed to undergo parathyroidectomy (PTx) due to either extremely high and persistent PTH levels or severe side effects of the medications. It is generally strongly advised that parathyroidectomies should be performed by an expert surgical team. In recent years, a significant decrease in parathyroidectomies has been recorded globally, a fact that is mainly linked to the constantly wider use of new calcimimetic agents. This decrease in parathyroidectomies has resulted in an important decrease in complications occurring in cervical surgeries (e.g., perioperative hemorrhage and nerve damage). Conslusions: Despite the fact that these surgical complications cannot be easily compared to the pharmaceutical side effects, the recorded decrease in parathyroidectomies is considered to be notable, especially in cases of relapse where a difficult reoperation would be considered based on previously published guidelines.

Real-life data on basal cell carcinoma treatment: Insights on clinicians' therapeutic choices from an institutional hospital registry.

Basal cell carcinoma (BCC) is the most common skin cancer in white skin individuals. The treatment of choice is surgical excision, but several other therapeutic choices are available and might also be efficient and cost-effective in selected cases of low-risk BCC or when surgery is complicate or contraindicated. The aim of the current study was to analyze the applied treatments for BCC in the real-life practice of a tertiary hospital, and investigate factors associated to the tumor and the patients that might influence the treatment selection of clinicians. Data on all BCCs treated from 1st January 2018 to 31st December 2019 were extracted. A total of 751 BCCs from 585 patients were included. The baseline characteristics of patients and tumors, the type of applied treatment and the histopathologic report when available were analyzed. Most tumors were located on the head/neck (64.2%). The most frequently applied treatment was surgical excision (580/751, 77.2%). In 22.8% of tumors a nonsurgical treatment was selected. The most frequently selected alternative treatments were, imiquimod, cryosurgery, their combination (immunocryosurgery), and vismodegib. A pretreatment diagnosis of superficial BCC was associated with a 12-fold increased probability of selecting a nonsurgical treatment except of vismodegib. Every added year of age increased the probability of selecting a nonsurgical treatment by 3-fold. Every added mm of diameter increased the possibility of vismodegib use by 4%. Surgery is the most frequently applied BCC treatment, but nonsurgical modalities do also have an essential role in real settings.

Hospitalization affects the anticoagulation patterns of patients with atrial fibrillation.

Scarce data are available on the effects of hospitalization on oral anticoagulation (OAC) patterns in patients with atrial fibrillation (AF). This study aimed to capture the evolving OAC patterns of patients with known non-valvular AF at high risk for stroke (CHA2DS2-Vasc score ≥ 2 for males and ≥ 3 for females) during hospitalization. A total of 561 eligible patients who were admitted to the cardiology ward of a tertiary hospital were studied. Pre- and post-hospitalization OAC patterns [vitamin-K antagonist (VKA), non-vitamin K oral anticoagulants (NOAC), no OAC], changes between these patterns (initiation, switch, discontinuation, no change) and the respective patient profiles and discharge diagnoses were assessed. During hospitalization, OAC administration increased from 73.1 to 86.6% of patients (p for trend < 0.001). NOAC use increased significantly (42.2-56.1%, p for trend < 0.001), whereas VKA use remained stable (30.8-30.5%). Of patients, 17.3% initiated OAC, 7.1% switched between OACs, 3.7% discontinued OAC treatment, while the rest underwent no change in anticoagulation status. Bleeding risk, use of concomitant antiplatelet therapy and incidence of primary discharge diagnosis of AF or ST-elevation myocardial infarction differed significantly between groups of initiation, switch, discontinuation and no change in OAC therapy. In conclusion, in patients with known AF at high risk for stroke, hospitalization was associated with an increase in OAC uptake, driven mainly by NOAC initiation. Three out of 10 patients initiated, switched or discontinued OAC treatment during hospitalization and this was associated with discrete epidemiologic parameters.

Ossification of the cervical ligamentum flavum and osseous brown tumor: late manifestations of primary hyperparathyroidism misdiagnosed in a case of parathyroid carcinoma.

Parathyroid carcinoma represents an extremely rare neoplasm with diverse clinical manifestations. Herein we aimed at presenting an unique case of a young patient with late manifestations of parathyroid cancer and reviewing the relevant literature. A 45-year-old male patient presented in the Outpatient Clinic with an episode of nephrolithiasis. His personal medical history includes: recurrent episodes of nephrolithiasis, laminectomy in the cervical spine due to ossification of the cervical ligamentum flavum and surgical resection of a giant cell tumor of the brain. Laboratory testing revealed findings of primary hyperparathyroidism (serum calcium 16,0 mmol/l phosphorus 1,46 mg/dl and parathyroid hormone/PTH 8560 pg/ml). Neck ultrasound and technetium-99 m sestamibi scan were performed showing a parathyroid tumor. Due to the persistently high serum calcium and PTH levels, the high alkaline phosphatase levels (440 IU/L) and the late manifestations of HPT, surgical excision of the tumor was performed. The tumor was identified as parathyroid carcinoma. Immediately after surgery serum calcium and phosphorus levels were normalized. The patient is on a regular follow-up program with no signs of recurrence or metastasis one year after the excision. We describe the coexistence of rare late manifestations of HPT, which had not been adequately investigated at their onset in this young patient. Therefore, increased awareness is needed in order to recognize and further investigate signs or symptoms of HPT.

Abiraterone-Induced Secondary Hypertension: Two Wrongs Don't Make a Right.

Abiraterone, an inhibitor of both 17α-hydroxylase and 17,20-lyase, is considered a novel, state-of-the-art, life-prolonging therapy in the urologists' arsenal when treating prostate cancer. Despite its efficacy, it is linked with an increased risk of cardiovascular adverse effects. Herein, we report a case in which the administration of abiraterone resulted in a full-blown syndrome of apparent mineralocorticoid excess despite the concomitant administration of prednisolone; that is, secondary hypertension, hypokalemia, metabolic alkalosis, as well as elevated levels of adrenocorticotropic hormone (ACTH).

Interleukin antagonists for atopic dermatitis: a new era of therapy.

INTRODUCTION: Over the last decade, increasing understanding of the immunopathogenesis of atopic dermatitis (AD) enabled the recognition of multiple therapeutic targets and subsequently the development of novel, highly effective systemic treatments, including interleukin (IL)-antagonists. To date, the IL-4Ra-inhibitor dupilumab and the IL-13 inhibitor tralokinumab have gained regulatory approval in Europe for the treatment of moderate-to-severe AD, while more than 70 new therapeutics are currently in development. AREAS COVERED: In this review, we address the role of ILs in the pathogenesis of AD and provide an overview of the novel and investigational IL-antagonists, as regards their efficacy and safety on moderate-to-severe AD. EXPERT OPINION: Current data have established IL-4 and IL-13 inhibitors as effective and safe for the treatment of moderate-to-severe AD, as regards the rapid control of flares as well as the long-term remission of the disease. Data regarding the efficacy and safety of other IL-inhibitors, including those targeting IL-31, IL-22, IL-33, IL-36 and IL-18, are accumulating. There is still an unmet need for real-world-evidence studies and head-to-head studies for both currently available and future agents in AD treatment. Establishing predictive biomarkers of treatment response in a disorder of such considerable heterogenicity might help physicians pursue a patient-tailored therapeutic response.

Tertiary hyperparathyroidism masking an atypical parathyroid tumor.

Atypical parathyroid tumors represent a group of parathyroid neoplasms of uncertain malignant potential. In view of preoperative diagnostic difficulties, suspicious features for malignancy may guide the surgeon to perform a radical surgical approach.

Insights into Early Systemic Treatment in Atopic Dermatitis: Scientific Facts and Practical Considerations.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized clinically by pruritus, and pathophysiologically by immune dysregulation, and compromised skin barrier function. While topical therapies are currently the cornerstone of AD management, especially in mild disease, recent advancements in systemic treatments and a deeper understanding of similar skin diseases, such as psoriasis, have highlighted the importance of early intervention. In this commentary, we explore the potential benefits of early systemic intervention in AD, with pruritus determining such a decision. Building on this concept, we assume that, through the timely systemic treatment that targets the immune dysregulation present in AD, the progression of the disease could be modified, improving overall patient outcomes. Early systemic intervention may minimize systemic inflammation, halting the "atopic march" and disrupting the "itch-scratch" cycle. Managing pruritus at its root could prevent secondary complications and reduce the psychosocial burden of the disease. This paradigm shift fosters a collaborative healthcare approach that empowers patients with long-term disease control strategies. In conclusion, the safety and efficacy of novel systemic treatments offer a compelling scenario for early intervention in atopic dermatitis care.

Cutaneous Small-Vessel Vasculitis Induced by Escitalopram: A Case-Based Brief Review of the Literature.

A 65-year-old male with multiple comorbidities and recently diagnosed with diabetic kidney disease developed upper and lower extremity rash following escitalopram initiation for his depressive mood. Clinical assessment and skin biopsy confirmed cutaneous small-vessel vasculitis (CSVV), prompting drug discontinuation and oral methylprednisolone therapy. The resolution of the rash was achieved within a week. This rare case of CSVV induced by escitalopram highlights the importance of timely recognition and management of drug-induced CSVV and adds to the limited literature on selective serotonin reuptake inhibitor-associated CSVV.

A Unique Case of Appendiceal Intussusception (Inversion): A Case in Bloom.

A 40-year-old female patient presented to a secondary facility with dull lower abdominal pain and a persistent low-grade fever. Her laboratory results showed elevated inflammation markers. A CT scan revealed two abscesses in the lesser pelvic region in direct contact with the apex of the appendix, the posterior wall of the uterus, and the right-side appendages. The patient responded well to intravenous antibiotics, and an MRI scan revealed the cause to be an appendiceal rupture. The patient was scheduled for an appendectomy. The procedure started laparoscopically but had to be converted to an open one with a midline infra-umbilical incision in order to protect the right appendages. A standard appendectomy was conducted, and the histology report revealed rupture of the appendix with concomitant wall inversion in the context of fibrous adhesions as well as obstruction due to a fecalith. Patient recovery and follow-up were excellent. Acute appendicitis, while frequently encountered in surgical practice, can present a diagnostic conundrum when it manifests in an atypical manner. This unique form of inversion appeared to confer a protective role against peritonitis, primarily through the mechanism of obstruction occurring centrally to the rupture. We suggest that this case should be included in current classifications as a partial inversion of the appendix after rupture and inflammation.

Neuroendocrine Breast Carcinoma: Interesting Images of an Underdiagnosed Entity.

Breast cancer is the most common type of cancer of the female gender. A rare subtype of breast cancer is the invasive breast carcinoma (IBC) with neuroendocrine (NE) differentiation. Its incident is believed to be 0.1% to 5% of all breast cancers. We report a rare case of a 66-year old woman who presented with an isolated nodule of the left breast. The patient underwent modified radical mastectomy. Pathology revealed invasive breast carcinoma with neuroendocrine differentiation. Invasive breast carcinoma is an extremely rare group of neoplasms, the exact frequency of which cannot be determined with current data. Therefore, it is necessary for future studies to focus on the pathophysiology of this subtype of breast cancer and on the potential therapeutic approaches.

Splenic infarction as a rare complication of infectious mononucleosis due to Epstein-Barr virus infection in a patient with no significant comorbidity: case report and review of the literature.

We report the case of a 17-y-old boy diagnosed with infectious mononucleosis due to Epstein-Barr virus infection who complained of left upper quadrant pain. A magnetic resonance imaging scan showed a splenic infarct in the enlarged spleen. Other causes of splenic infarction were excluded. Thus, infectious mononucleosis may cause splenic infarction in patients without other comorbidities.

Antisynthetase Syndrome: The Classical Phenotype With a Twist.

Antisynthetase syndrome is a systemic autoimmune rheumatic disease characterized by multiple organ involvement, including interstitial lung disease, myositis, non-erosive arthritis, fever, Raynaud's phenomenon, "mechanic's hands," and the presence of autoantibodies against aminoacyl-tRNA synthetases, mainly anti-Jo1 (histidyl) antibodies. Patients with antisynthetase syndrome and active muscle inflammation are usually presented with elevated creatine phosphokinase levels, even in the range of acute rhabdomyolysis. Despite that, the presence of myoglobinuric acute kidney injury is rarely seen in patients with myositis-associated rhabdomyolysis. Herein, we report the case of a 64-year-old man who presented with acute kidney injury due to severe rhabdomyolysis in the setting of antisynthetase syndrome diagnosed by the classical clinical triad of (1) interstitial lung disease, (2) non-erosive arthritis, and (3) active myositis and the presence of anti-Jo1 antibodies. The diagnosis was confirmed by muscle biopsy histological findings as well as electromyography. In this case report, we also discuss the classical clinical manifestations of antisynthetase syndrome and a twist toward this unusual complication associated with active muscle inflammation.

Uremic Leontiasis Ossea: Theoretical Concepts and Practical Considerations.

Leontiasis ossea (LO) in chronic kidney disease patients, also known as Sagliker syndrome, is an exceptionally uncommon uremic complication of long-lasting and severe secondary hyperparathyroidism. The prominent features of uremic LO (ULO) encompass the characteristic clinical trial of massive thickening of maxillary and mandibular bones, widening of interdental spaces, and flattening of nasal bridges and nares. Moreover, during the transformation of craniofacial architecture, significant structural and functional consequences may appear, including upper airway patency, visual and hearing acuity, oral phase of swallowing as well as various neurological and psychiatric disorders. Only few cases of ULO have been reported in the literature until now, making challenging not only the traditional diagnostic procedures but also the optimal therapeutic approach. In this narrative review, we aim to explore the underlying pathophysiological mechanisms, summarize the evidence for adverse outcomes, and highlight the current therapeutic strategies for ULO prevention and treatment, given that precise genetic determinants remain elusive.

New and Upcoming Topical Treatments for Atopic Dermatitis: A Review of the Literature.

Atopic dermatitis (AD) is a chronic inflammatory dermatosis with periods of exacerbation and remissions. AD is characterized by intense, persistent pruritus and heterogeneity in clinical symptomatology and severity. Therapeutic goals include the amelioration of cutaneous eruptions, diminishing relapses and eventually the disease burden. To date, topical corticosteroids (TCS) and calcineurin inhibitors (TCI) have yet been deemed the mainstay of topical treatments in AD management. Nevertheless, despite their indisputable efficiency, TCS and TCI are not indicated for continuous long-term use given their safety profile. While research in AD has concentrated predominantly on systemic therapies, more than 30 novel topical compounds are under development. The existing data appear encouraging, with some regimens that are already FDA-approved (ruxolitinib was the most recent in September 2021) and several pharmaceutical pipeline products for mild-to-moderate AD that are in an advanced stage of development, such as tapinarof, difamilast and roflumilast. Larger, long-term studies are still required to evaluate the efficacy and safety of these novel compounds in the long run and weigh their advantages over present treatments. In this review, we aim to provide an overview of the latest knowledge about AD topical treatments, echoing upcoming research trends.

Rosuvastatin and Colchicine combined myotoxicity: lessons to be learnt.

Statins and colchicine co-administration consists of a potentially catastrophic drug-drug interaction since it provokes myotoxicity, myopathy and various degrees of rhabdomyolysis. Lipophilic statins and colchicine are biotransformed in the liver, primarily via CYP3A4 enzyme system leading to elevated blood levels of both agents and resulting in increased potential for combined myotoxicity. Hence, it would be of great clinical importance not only the awareness of this devastating complication but also the more advantageous type of statin that we should choose to achieve the recommended therapeutic goals regarding LDL levels with minimal myopathy risk. Therefore, once colchicine's use is commenced, a hydrophilic statin selection, such as rosuvastatin, seems favorable regarding the risk of myotoxicity. Herein, we aim to describe a patient with chronic kidney disease stage III and nephrotic syndrome that developed acute rhabdomyolysis soon after the administration of rosuvastatin while receiving colchicine. To the best of our knowledge, this is the first report of the combined effect of rosuvastatin and colchicine in the setting of chronic kidney disease leading to myotoxicity.

Dermatoscopy of melanoma according to type, anatomic site and stage.

The indisputable contribution of dermatoscopy in early diagnosis of melanoma is widely recognized. In the last quinquennium, new data concerning specific melanoma subtypes have come to light. The dermatoscopic morphology of superficial spreading melanoma (SSM) has been extensively investigated in the literature. Atypical network, irregular dots, irregular globules, irregular streaks and irregular blotch correspond to histopathologic alterations at the level of the junction, blue-white veil and atypical vessels suggest intradermal growth, whereas regression structures, negative network and white shiny streaks might reflect junctional or dermal alterations. The list of melanoma specific criteria has been recently updated to include features that typify early melanoma, such as irregular hyperpigmented areas and prominent skin markings and features seen in melanoma on sun damaged skin such as angulated lines. Nodular melanoma lacks most of the aforementioned criteria and is typified by the coexistence of blue and black color, atypical vessels and pink color. Lentigo maligna dermatoscopic criteria mainly develop at the outline of the follicular openings. However, at an early stage these features might be very subtle and the diagnosis should be based on the exclusion of benign tumors (inverse approach). Acral lentiginous melanoma is typified by a parallel ridge pattern, but also SSM criteria should be taken into consideration. The diagnosis of subungual melanoma is based on the assessment of the color and characteristics of the pigmented nail band. For the diagnosis of mucosal melanoma, the assessment of colors is more informative than the assessment of structures and the detection of blue, white or gray should raise the suspicion of melanoma. White shiny streaks and regression structures are the most common features of desmoplastic melanoma. The diagnosis of nevoid melanoma might be highly challenging and require information on the lesion's history. Melanoma on small- and medium-sized congenital nevi is typified by an eccentric location of the suspicious area, negative network and gray angulated lines. Recent advances in knowledge on the dermatoscopic characteristics of peculiar subtypes of the tumor significantly enrich the diagnostic armamentarium of clinicians. The challenge of the forthcoming years is to better characterize biologically aggressive melanomas and to optimize the screening strategies so as to identify them.

Motivational Interviewing to Support Oral AntiCoagulation adherence in patients with non-valvular Atrial Fibrillation (MISOAC-AF): a randomized clinical trial.

AIMS: We aimed to assess the impact of an educational, motivational intervention on the adherence to oral anticoagulation (OAC) in patients with non-valvular atrial fibrillation (AF). METHODS AND RESULTS: Hospitalized patients with non-valvular AF who received OAC were randomly assigned to usual medical care or a proactive intervention, comprising motivational interviewing, and tailored counselling on medication adherence. The primary study outcome was adherence to OAC at 1 year, which was evaluated according to proportion of days covered (PDC) by OAC regimens and was assessed through nationwide registers of prescription claims. Secondary outcomes included the rate of persistence to OAC, gaps in treatment, and clinical events. A total of 1009 patients were randomized, 500 in the intervention group and 509 in the control group. At 1-year follow-up, 77.2% (386/500) of patients in the intervention group were adherent (PDC > 80%), compared with 55% (280/509) in the control group [adjusted odds ratio (aOR) 2.84, 95% confidence interval (CI) 2.14-3.75; P < 0.001]. Mean PDC ± standard deviation was 0.85 ± 0.26 and 0.75 ± 0.31, respectively (P < 0.001). Patients that received the intervention were more likely to persist in their OAC therapy at 1 year (aOR 2.42, 95% CI 1.71-3.41; P < 0.001). Usual medical care was associated with more major (≥3 months) treatment gaps (aOR 2.39, 95% CI 1.76-3.26; P < 0.001). Clinical events over a median follow-up period of 2 years did not differ among treatment groups. CONCLUSION: In patients receiving OAC therapy for non-valvular AF, a multilevel motivational intervention significantly improved medication adherence and rate of therapy persistence, and reduced major gaps in treatment. No significant impact on clinical outcomes was observed. TRIAL REGISTRATION NUMBER: NCT02941978.
