Epidermodysplasia Verruciformis acquired in an HIV-positive patient

The disease epidermodysplasia verruciformis is a rare genodermatosis, autosomal recessive in most cases, characterized by susceptibility to infection by types of HPV of the genus β (EV-HPV) that do not occur in immunocompetent clinics. With the increased survival of immunosuppressed patients, especially with AIDS, a form of the disease called epidermodysplasia verruciformis acquired from a clinician similar to the genetic disease has been reduced, but challenging to manage, since an antiretroviral therapy leads to a cutaneous one, making patients more resistant to any treatment modality

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Diagnosis of epidermoid carcinoma of the tongue after treatment of epidermoid carcinoma of the esophagus

In the present case report, a patient with esophageal squamous cell carcinoma (SCC) developed a second primary tumor in the tongue at the same time. Stage III middle esophageal SCC was discovered in a 60-year-old Caucasian male patient who was institutionalized, a smoker, and had previously struggled with alcoholism. Following treatment, the patient was admitted to the hospital for 15 days due to dysphagia and malnutrition. According to him, he had mouth pain while in the hospital. An intraoral examination revealed tooth mobility, bacterial plaque, dental calculus, and a 1.3-cm ulcerated lesion on the right lateral edge of the tongue. During the extraoral examination, no palpable lymph nodes were found in the submandibular or cervical regions. The tongue lesion was excisionally biopsied, and the histological evaluation agreed. The patient was advised to seek treatment for tongue SCC. Given that patients with esophageal SCC have a 9.3%–11.4% risk of developing head-and-neck SCC, multiprofessional follow-up of patients with esophageal SCC is critical for early detection of this cancer
