Intradialysis hypertension, a diagnosis to be discovered.

Introduction: Intradialytic hypertension (IDH) is a poorly understood phenomenon with no consensus on its definition, etiology, or related factors, and there is limited evidence on its consequences.

Objective: To determine the prevalence of IDH according to different definitions in hemodialysis (HD) units, with different clinical practices and assessment of possible events after 18 months have passed.

Materials And Methods: A cross-sectional observational study was conducted in 2 HD units, including all prevalent patients from March 2021 to September 2022.

Hyperaldosteronism and hyperparathyroidism. A disturbing friendship.

Classically, aldosterone actions are associated with the stability of the effective circulating volume and with blood pressure control, while parathormone actions are linked to bone mineral metabolism, calcium, and phosphate homeostasis. Nevertheless, the relationship between these two hormonal axes surpasses these areas. A bidirectional interrelation between calcium-phosphorus metabolism and blood pressure control can lead to alterations in both.

E-cigarette, or vaping, product use Associated Lung Injury (EVALI): new scenarios for physicians and radiologists.

A 59-year-old female ex-smoker with 40 pack year smoking history and a 5-year current e-cigarette (EC) use history, presented with progressive dyspnea on exertion and daily cough for 2 months. A CT scan showed a consolidation area with air bronchogram in the middle lobe and non-calcific bilateral nodules, which could be attributed to community-acquired pneumonia. The patient was treated with empiric antibiotics and systemic steroids for 10 days.

Acute kidney injury in 3182 patients admitted with COVID-19: a single-center, retrospective, case-control study.

Background: Acute kidney injury (AKI) may develop in coronavirus disease 2019 (COVID-19) patients and may be associated with a worse outcome. The aim of this study is to describe AKI incidence during the first 45 days of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in Spain, its reversibility and the association with mortality.

Methods: This was an observational retrospective case-control study based on patients hospitalized between 1 March and 15 April 2020 with SARS-CoV-2 infection and AKI.

High prevalence of asymptomatic COVID-19 in haemodialysis: learning day by day in the first month of the COVID-19 pandemic.

Dialysis patients are a risk group for SARS-CoV-2 infection and possibly further complications, but we have little information. The aim of this paper is to describe the experience of the first month of the SARS-CoV-2 pandemic in a hospital haemodialysis (HD) unit serving the district of Madrid with the second highest incidence of COVID-19 (almost 1,000 patients in 100,000h). In the form of a diary, we present the actions undertaken, the incidence of COVID-19 in patients and health staff, some clinical characteristics and the results of screening all the patients in the unit.

Sentinel lymph node biopsy in the treatment of breast cancer. Experience in 527 cases.

Aim: Knowledge of axillary lymph node status is a key aid to staging and prognosis and it represents a guideline for adjuvant therapy in breast cancer. Despite the morbidity it causes, complete axillary dissection was long the mainstay of treatment. Sentinel lymph node biopsy has proved so reliable in the evaluation of node involvement that axillary node dissection is now generally performed when sentinel node biopsy tests negative.

[Ductal carcinoma in situ of the breast].

The Authors report their experience about 127 ductal carcinoma in situ (DCIS) of the breast. Guidelines for surgical treatment are: radiological or clinical diagnosis, tumor's extension, histological classification, grading and margin status. At the present the Authors prefer breast conserving surgery with tumor margin's study.

[Modulation of the axillary lymph node dissection in breast cancer].

Unlabelled: Several studies showed the reliability of the sentinel lymph node (SN) technique in the evaluation of the N parameter in breast cancer so much to induce surgeons to limit the axillary dissection to the biopsy of the SN alone (SNB) in case this is negative to the extemporaneous examination. After a period of focusing on the identification technique, biopsy and histological examination of the SN (October 97-January 98) always followed by a complete dissection of the three axillary node levels (ALND), we started a study to evaluate the reliability of a limited dissection of the 1st level of the axilla (FLND) in women with T < 3 cm, N0-1a, M0, that did not undergo any neoadjuvant treatment and in which the SN resulted free from metastases. We started this phase of the study in February 1998 till May 2001.

[Intraoperative cholangiography in videolaparoscopic cholecystectomy: indications, advantages, and limitations].

Consensus doesn't exist about the intraoperative cholangiography specially if is need in every one laparoscopic cholecystectomy either exclusively in case of anatomical doubts or suspect of injures or stones of the common duct. We have considered 450 patient subjected to laparoscopic cholecystectomy during 1992-2000. Patients suspicious to be affected by common duct lithiasis (28 cases) are subjected to ERCP with cleaning of the biliary tree.

[Septic complications of gallbladder lacerations during laparoscopic cholecystectomy].

The iatrogenic gallbladder perforation with bile and, eventually, gallstones loss in the peritoneal cavity happens in the laparoscopic cholecystectomies more frequently than in the laparotomic ones. The authors have reviewed their experience and recent bibliography with the aim to clarify factors that increase risks for this adverse effect; 579 patients subjected to laparoscopic cholecistectomy: in 81 cases (13.98%) the intra-peritoneal perforation of the gallbladder wall has happened, in 26 associated to gallstones loss; 12 of these last have developed abdominal wall infections.

[Direct experience in the treatment of unusual, primary, and secondary malignant tumors of the stomach].

The reduced incidence of gastric cancer, due to a better patients surveillance and more accurate understanding of prophylactic measure, has allowed a detection of early stages as well as cancers with different origin cells. Either the difficulty of differential diagnosis or the various surgical and integrated approaches, make these neoplasm hard to enroll in standard treatment protocols. Our experience consists of 5 clinical cases with four different histology: lymphoma, leiomioma, carcinoid and gastrinoma.
