Long-term Prophylaxis with Androgens in the management of Hereditary Angioedema (HAE) in emerging countries.

Hereditary angioedema (HAE) is a rare autosomal dominant genetic disease characterized by repetitive subcutaneous or submucosal angioedema, activation of the kinin system, and increased vascular permeability. C1-inhibitor (C1-INH) deficiency, the main mechanism of HAE pathogenesis, occurs when abnormal activation of plasma kallikrein, bradykinin, and factor XII, or mutation of genes such as SERPING1 cause quantitative or functional C1-INH defects. Although androgens are not approved for HAE treatment in many countries, they are widely used in China and Brazil to reduce the frequency and severity of HAE attacks. The long-term adverse effects of androgen treatment are concerning for both physicians and patients. Virilization, weight gain, acne, hirsutism, liver damage, headache, myalgia, hematuria, menstrual disorders, diminished libido, arterial hypertension, dyslipidemia, and anxiety/depression are commonly observed during long-term treatment with androgens. These adverse effects can affect the quality of life of HAE patients and often lead to treatment interruption, especially in women and children. In-depth studies of the pathogenesis of HAE have led to the approval of alternative treatment strategies, including plasma-derived C1 inhibitor, recombinant human C1 inhibitor, plasma Kallikrein inhibitor (ecallantide; lanadelumab), and bradykinin B2 receptor antagonist (icatibant), some of which have achieved satisfactory results with mostly non-serious side effects. Therefore, a new standard of medical care may expand possibilities for the management of HAE in emerging countries.

Severe intrahepatic cholestasis of pregnancy due to a Sertoli-Leydig cell tumour in a woman with polycystic ovary syndrome: a case report.

Intrahepatic cholestasis of pregnancy (ICP) is a common gestational complication characterized by pruritus and elevated bile acids, usually occurring in the third trimester when the serum estrogen and progesterone levels are highest. Hyperandrogenism during pregnancy is a pathological state that is mostly induced by polycystic ovary syndrome (PCOS) but rarely by concomitant androgen-secreting ovarian tumours. To date, no correlation has been drawn between ICP and hyperandrogenism.

Follow-Up by Transcranial Doppler After Rupture of a Giant Intracranial Aneurysm.

Giant intracranial aneurysms (GIA) are rare and manifest primarily through subarachnoid hemorrhage (SAH), cerebral ischemia, or progressive symptoms of mass effect. Transcranial Doppler (TCD) can be used to monitor cerebral vasospasm after treatment of intracranial aneurysm allowing the adjustment of therapeutics and avoiding complications. The authors present a clinical case of a patient with a ruptured intracranial giant aneurysm in which TCD was essential to monitor vasospasm and intracranial hypertension (IH). A 53-year-old male was admitted due to a sudden headache and impaired consciousness, left hemiparesis, and dysarthria. Cerebral CT scan and CT angiography at admission showed a giant aneurysm of the right middle cerebral artery (MCA) with extensive and diffuse intraventricular SAH of Fisher grade IV and Hunt and Hess grade 4. Clipping, placement of an intracranial pressure sensor, and external ventricular drain (EVD) were performed on the same day, with difficulty in preserving the M2 branch and complicated by postoperative extensive right MCA ischemia. On day three of hospitalization, TCD revealed an increased pulsatility index (>1.5) with clinical deterioration leading to re-intervention for a decompressive craniectomy. On day six, a TCD follow-up was performed to monitor blood flow complications, and particularly vasospasm, showing a severe increase in middle blood flow velocity (MBFV) in the right MCA of 205 cm/s and Lindegaard Index > 6. Daily surveillance by TCD was maintained to guide clinical management since the attempt to withdraw the EVD led to clinical deterioration with subsequent worsening of vasospasm. Improvement occurred after surgery as ventriculoperitoneal shunt insertion was performed. TCD had a major role in the clinical orientation of SAH as well as in intracranial pressure management and was decisive to establish long-term treatment.

Successful Use of Continuous Erector Spinae Plane Blocks in a Patient With Variant Angina After Large Ventral Hernia Repair.

Coronary artery spasm constitutes the primary underlying pathology of variant angina. Because provocation of coronary artery spasm may occur with both excess sympathetic and excess parasympathetic stimulation, patients with this disorder have extremely limited options for perioperative pain control. This is especially true for procedures involving extensive abdominal incision/manipulation. Whereas neuraxial analgesia might otherwise be appropriate in these cases, several studies have demonstrated that coronary artery spasm can occur as a result of epidural placement, and therefore, that this may not be an optimal choice for patients with variant angina. This report discusses the case of a patient with a preexisting diagnosis of variant angina who underwent an exploratory laparotomy with large ventral hernia repair and for whom continuous erector spinae plane blocks were successfully used as analgesic adjuncts without triggering coronary artery spasm.

Bullous Hemorrhagic Dermatosis: A Rare Benign Cutaneous Complication of Low-Molecular-Weight Heparin.

Enoxaparin-mediated bullous hemorrhagic dermatosis (BHD) is one of the rare side effects during prophylaxis of enoxaparin for various thromboembolic events. We report a case of a 74-year-old female with multiple comorbidities who developed BHD at a distant site from subcutaneous delivery of enoxaparin. Histopathological analysis confirmed the diagnosis of BHD. Discontinuation of enoxaparin resulted in the gradual resolution of the bullae formation, and the patient was started on novel oral anticoagulation with apixaban. The usual cutaneous adverse effects of enoxaparin include maculopapular rash, pruritus, skin necrosis, eczematous dermatitis, and rarely bullous hemorrhagic dermatosis. This hemorrhagic bullae dermatosis at a distant site from the administration is a relatively rare and benign side effect of enoxaparin which is an under-recognized complication of low-molecular-weight heparin.

Tender Nasal Traumatic (TNT) Neuroma: Case Report and Review.

A traumatic neuroma occurs at the injury site of a peripheral nerve; however, albeit rarely, this variant of a neuroma can involve a nerve that has not experienced penetrating trauma. A lower extremity amputation stump is the most common location of a traumatic neuroma. Traumatic neuromas may be symptomatic; tumor-associated pain can be severe and significantly affect the patient's quality of life. Several hypotheses have been postulated for the pathogenesis of neuroma-related pain, including alpha-smooth muscle actin, neural fiber structural changes, nerve growth factor, and/or sensitization of the affected nerve. In addition to prevention, non-surgical treatment (such as chemical interventions, cryotherapy, neuromodulation, pharmacologic agents, and physiotherapy) and surgical interventions (such as direct nerve repair at the time of injury or ligation of the nerve proximal to the neuroma and various potential methods to minimize subsequent irritation of the distal free end of the proximal nerve) have been used to manage neuroma-associated pain. A traumatic neuroma of the nose is rare. Indeed, it has only been described in three individuals: two women (including the Caucasian woman in this report and a Turkish woman) and one man. The benign tumor was extremely painful in both women; however, the man's lesion was non-tender. Prior trauma to the nasal site included either a laceration or elective surgery; however, the reported woman did not experience any penetrating trauma to her nose. The diagnosis was established following an excisional (for the man), incisional (for the Turkish woman), or punch (for the Caucasian woman) biopsy. Follow-up was provided for two of the patients. The man's neuroma had been completely excised, and he never developed tumor-associated tenderness. However, the pain persisted after the biopsy healed for the reported woman whose neuroma was not entirely removed. The explosive and markedly severe character of the reported patient's lesion-related tenderness prompted us to propose an acronym for this uncommon yet exquisitely painful variant of a neuroma: tender nasal traumatic (TNT) neuroma.

Full of twists and turns: Collecting duct carcinoma presenting as persistent cough.

We report a case of collecting duct carcinoma (CDC) in a 60-year-old man who presented with persistent cough, low back pain, and weight loss. Contrast-enhanced CT of chest and abdomen revealed a mass in the medulla of the middle and upper parts of the right kidney, with spread into perirenal tissue, vascular invasion, and distant metastasis. First renal biopsy only showed inflammation. Repeat biopsy and histopathological examination and immunohistochemistry confirmed CDC. The patient died 2 months after diagnosis despite interventional therapy, chemotherapy, and targeted therapy. This case is being reported because of its rarity and unusual presentation.

Sensory Symptoms Associated with Aesthetic Botulinum Toxin A Treatments.

A retrospective review of patients who switched from onabotulinumtoxinA (onaA) and/or abobotulinumtoxinA (aboA) to incobotulinumtoxinA (incoA) found anecdotal reports of differences in "feel," including a "lighter" feel or treatment-associated tightness. We surveyed the frequency of these sensations as an initial proof of concept of toxin proprioception among our patients who switched toxins.
