Management of Peritoneal Dialysis-Associated Emergencies during the COVID-19 Pandemic: The Experience of a Center of Excellence.

The COVID-19 pandemic struck unexpectedly; emergency services and chronic care institutions, including dialysis centers, were overloaded. A significant problem was the care of COVID-positive patients alongside the care of chronically dialyzed patients who presented emergencies. In our hospital, which became a COVID support center for dialysis patients with severe forms of the disease, we had to care for PD patients with dialysis-related emergencies. We present two cases of patients managed on an outpatient basis or 1-day hospitalization who were treated successfully without compromising the quality of the care provided. We used remote monitoring, worked in a multidisciplinary team, and shortened the duration of the patients' hospitalization (and implicitly the risk of contact). In pandemic conditions, the advantage of PD was the possibility of patient isolation; in the first 6 months of the pandemic, we recorded no deaths in this category of patients. In hemodialysis patients, infection and mortality rates were high. Although we expected an increase in the number of peritoneal dialysis patients in the post-pandemic period, this did not happen. We continue to plead for the popularization of the PD method among patients and doctors, which has proven advantages in pandemic conditions.

Peritoneal Dialysis-Induced Encapsulating Peritonitis: Diagnostic and Therapeutic Challenges in Women with Benign Gynecological Pathology.

Background: Peritoneal sclerosis (PS) and its most severe form, encapsulating PS (EPS), are rare entities that can occur in various procedures (liver transplantation, intraperitoneal chemotherapy) or secondary to medications (beta-blockers); however, PS or EPS typically occur in patients undergoing peritoneal dialysis as a form of renal function substitution. Medical or surgical treatments can be applied, but morbidity and mortality have high rates. This condition typically presents clinically as an intestinal obstruction caused by the inclusion of the intestinal loops in the peritoneal fibrous membrane. Methods: Herein, we present data from a single tertiary surgery center that has dedicated teams for patients receiving dialysis. Over 12 years, we analyzed a group of 63 patients admitted for catheter replacement/removal or for acute surgical pathology. In five cases (7.9%), we diagnosed EPS. Two patients with EPS presented with atypical abdominal pathologies requiring emergency surgery: one case of hemoperitoneum caused by a ruptured ovarian cyst and one case of uterine fibroids and metrorrhagia. Results: The definitive diagnoses were established intraoperatively and by analyzing the morpho-pathological changes in the peritoneum. The possible intraoperative challenges included laborious dissection, difficulties in restoring the correct anatomical landmarks, an increased duration of the surgical intervention and a high rate of incidents and accidents. Conclusions: The aim of the present study was to emphasize the possibility of other surgical pathologies overlapping with EPS, increasing the complexity of the surgical intervention.

Advantages of total parathyroidectomy in patients with secondary hyperparathyroidism induced by end stage renal disease.

Introduction: Secondary hyperparathyroidism, as a result of chronic kidney disease could be treated medically or surgically. When pharmacotherapy fails, patients undergo surgery - parathyroidectomy, the curative treatment of secondary hyperparathyroidism (SHPT). There are currently 3 accepted surgical techniques, each with supporters or opponents - total parathyroidectomy, subtotal parathyroidectomy and parathyroidectomy with immediate autotransplantation. Methods: In this paper we described our experience on a series of 160 consecutive patients diagnosed with secondary hyperparathyroidism who underwent surgery, in 27 cases it was totalization of the intervention (patients with previously performed subtotal parathyroidectomy or with supernumerary glands and SHPT recurrence). We routinely perform total parathyroidectomy, the method that we believe offers the best results. Results: The group of patients was studied according to demographic criteria, paraclinical balance, clinical symptomatology, pre- and postoperative iPTH (intact parathormone) values, SHPT recurrence, number of reinterventions. In 31 cases we found gland ectopy and in 15 cases we discovered supernumerary parathyroids. A percentage of 96.24% of patients with total parathyroidectomy did not show recurrence. Discussions: After analyzing the obtained results, our conclusion was that total parathyroidectomy is the intervention of choice for patients suffering from secondary hyperparathyroidism when pharmacotherapy fails in order to prevent recurrence of the disease and to correct the metabolic parameters.

Parameters for Predicting Tumour Response Following Neoadjuvant Chemoradiotherapy for Patients with Rectal Cancer.

Introduction: Pathologic response following neoadjuvant chemoradiotherapy (nCRT) can vary from pathologic complete response (pCR), to tumour downstaging or minimum to no response. Our goal was to evaluate the parameters that could predict response to neoadjuvant therapy for patients with rectal cancer. Method: We performed a retrospective study and reviewed the medical documentation for patients that received treatment for rectal cancer in our surgical department between 2014-2018 and received nCRT. Results: A total of 98 patients were included in the study. 66 patients were males (67,3%) and 32 were females (32,7%). The mean age was 64,6 (39-87). The 48 months overall survival rate was 81,63% and the 48 months disease-free survival rate was 69,38%. Tumour grading was considered as a statisti cally significant parameter for evaluating the pathologic response. The tumours most likely to respond to radio-chemotherapy were G1 or G2 grade. T4 tumours compared with lesser T stages were less likely to achieve pathologic complete response. Elevated CEA levels predicted a poor pathologic response to nCRT. Conclusion: Our study concluded that tumour related factors, biologic and imagistic findings such as tumour stage, lymph node, tumour differentiation grade and CEA levels can be used as parameters for predicting the tumour response following neoadjuvant therapy.

The Value of Endoscopy as a Predictive Factor when Evaluating the Clinical Response to Neoadjuvant Chemoradiotherapy for Patients with Rectal Cancer.

Introduction: Standard treatment rectal cancer according to numerous international guidelines recommends neoadjuvant chemoradiotherapy (nCRT). Literature data suggests that a better response to nCRT (greater tumour regression) leads to improved overall survival rates (OS) and disease-free survival rates (DFS). Tumour response to nCRT can be assessed either through clinical or pathological examination. The clinical tumour response is evaluated via a digital rectal examination, endoscopy (with or without ultrasound) and DWI-MRI. Our goal was to see if, when evaluating the clinical response to neoadjuvant chemoradiotherapy we can rely on the endoscopic findings and if it could have a predictive value for the overall outcomes. Method: A retrospective study was performed on 43 patients that were treated for rectal cancer in our clinic following neoadjuvant chemoradiotherapy. We divided the patients into two groups regarding the endoscopy grading. Results: Patients with a better response (endoscopy good grade) had a better disease free survival rate and lower recurrence rate compared to patients with a endoscopy low grade (86,5% vs 56,6%) and (10.34% vs 42,85%). Conclusion: Endoscopy could be a useful tool in appreciating the tumour response to nCRT, and further research is needed in determining the best method for evaluating clinical response to neo adjuvant therapy in patients with rectal cancer.

[Pulmonary hydatic cyst--a case report]. / Chist hidatic pulmonar--prezentare de caz.

We present the case of a patient diagnosed in our clinic with pulmonary hydatid cyst, the discovery being incidental, during the investigations for a febrile syndrome accompanied by cough and thoracic pain. Pulmonary Hydatidosis is a disease caused by the location and growing inside the lungs of larval form of Taenia echinococcus granulosus, the way of infection is digestive. Hydatid cyst is a rare pathology, the incidence is higher in some populations related to professions such as sheep or goat raising. Pulmonary cyst diagnosis is made by imagistic methods (chest x-ray, CT, MRI) and bio-umoral methods (white cell count, specific serology), anamnesis and clinical exam can be inconclusive. The treatment of the hydatid cyst is surgical, medical treatment (antibiotic, parasiticid) has some specific indication. We administer antibiotics when we have bacterial suprainfection and parasiticid postoperatively for preventing recurrences or when we suspect rupture of the cyst. From the surgical methods cystectomy followed by capitonnage of the residual cavity (Dor procedure) is to be chosen, so that this fulfills the objectives of removing the cyst and treating the residual cavity with preserving as much as possible from the lung tissue.
