Risk Factors for Hypoparathyroidism after Thyroid Surgery: A Single-Center Study.

BACKGROUND: Hypoparathyroidism is one of the most common complications after thyroidectomy. This study evaluated the incidence and potential risk factors for postoperative hypoparathyroidism after thyroid surgical procedures in a single high-volume center. METHODS: In this retrospective study, in all patients undergoing thyroid surgery from 2018 to 2021, a 6 h postoperative parathyroid hormone level (PTH) was evaluated. Patients were divided into two groups based on 6 h postoperative PTH levels (≤12 and >12 pg/mL). RESULTS: A total of 734 patients were enrolled in this study. Most patients (702, 95.6%) underwent a total thyroidectomy, while 32 patients underwent a lobectomy (4.4%). A total of 230 patients (31.3%) had a postoperative PTH level of <12 pg/mL. Postoperative temporary hypoparathyroidism was more frequently associated with female sex, age < 40 y, neck dissection, the yield of lymph node dissection, and incidental parathyroidectomy. Incidental parathyroidectomy was reported in 122 patients (16.6%) and was correlated with thyroid cancer and neck dissection. CONCLUSIONS: Young patients undergoing neck dissection and with incidental parathyroidectomy have the highest risk of postoperative hypoparathyroidism after thyroid surgery. However, incidental parathyroidectomy did not necessarily correlate with postoperative hypocalcemia, suggesting that the pathogenesis of this complication is multifactorial and may include an impaired blood supply to parathyroid glands during thyroid surgery.

Abdominal wall complications after kidney transplantation: A clinical review.

INTRODUCTION: Abdominal wall complications are common after kidney transplantation, and although they have a minor impact on patient and graft survival, they increase the patient's morbidity and may have an impact on quality of life. Abdominal wall complications have an overall incidence of 7.7-21%. METHODS: This review will explore the natural history of abdominal wall complications in the kidney transplant setting, with a special focus on wound dehiscence and incisional herni, with a particular emphasis on risk factors, clinical characteristics, and treatment. RESULTS: Many patient-related risk factors have been suggested, including older age, obesity, and smoking, but kidney transplant recipients have an additional risk related to the use of immunosuppression. Wound dehiscence usually does not require surgical intervention. However, for deep dehiscence involving the fascial layer with concomitant infection, surgical treatment and/or negative pressure wound therapy may be required. CONCLUSIONS: Incisional hernia (IH) may affect 1.1-18% of kidney transplant recipients. Most patients require surgical treatment, either open or laparoscopic. Mesh repair is considered the gold standard for the treatment of IH, since it is associated with a low rate of postoperative complications and an acceptable rate of recurrence. Biologic mesh could be an attractive alternative in patients with graft exposition or infection.

Risk Factors for Low Levels of Parathyroid Hormone after Surgery for Thyroid Cancer: A Single Center Study.

BACKGROUND: Thyroidectomy is the definitive treatment for most patients with thyroid cancer. Hypoparathyroidism is the most frequent complication of thyroidectomy, and its pathogenesis is multifactorial. The aim of this study is to evaluate the patient- and surgical-related risk factors for hypoparathyroidism after surgery for thyroid cancer. METHODS: In this retrospective study, patients referred to surgery for thyroid cancer from 2016 to 2019 were enrolled. Preoperative serum calcium and parathyroid hormone (PTH) and postoperative 24 h PTH and calcium levels were evaluated. Demographic data, type of surgery, incidence of hypoparathyroidism and hypocalcemia were recorded for all the patients. Patients were divided into two groups based on post-operative PTH levels (≤12 and >12 pg/mL). RESULTS: A total of 189 patients were enrolled in this study. There were 146 women (87.3%) and 43 men (22.7%), with a mean age of 51.3 years. A total of 79 patients (41.7%) underwent a neck dissection. A total of 59 patients (31.1%) had a postoperative PTH level < 12 pg/mL. Female sex, neck dissection, the yield of lymph node dissection and incidental parathyroidectomy were significantly associated with postoperative hypoparathyroidism. Incidental parathyroidectomy was reported in 44 (23.2%) patients and was correlated with younger age (<40 years) and neck dissection. There was no difference in the rate of post-operative hypocalcemia between patients with incidental parathyroidectomy and those without. CONCLUSIONS: Young patients undergoing neck dissection and with incidental parathyroidectomy have the highest risk of postoperative hypoparathyroidism after surgery for thyroid cancer. However, a large proportion of patients without incidental parathyroidectomy may have temporary hypocalcemia, suggesting that impaired blood supply of parathyroid glands during their identification and dissection may play a relevant role.

Colorectal Cancer after Kidney Transplantation: A Screening Colonoscopy Case-Control Study.

The incidence of colorectal cancer in kidney transplant recipients has been previously reported with conflicting results. In this study, we investigated if the incidence of colorectal advanced neoplasms in kidney transplant recipients, evaluated with screening colonoscopy, was higher than in healthy individuals. One-hundred sixty kidney transplant recipients undergoing screening colonoscopy were compared with 594 age- and sex-matched healthy individuals. Advanced colorectal neoplasia was found in 22 patients (13.7%), including four patients (2.5%) with colorectal cancer. Compared with the healthy population, kidney transplant recipients did not have an increased risk of developing a colorectal cancer (OR 0.69; 95% CI 0.236-2.063, p = 0.688) although it developed at a younger age. In contrast, kidney transplant recipients had a higher risk of developing an advanced adenoma compared with the control group (OR 1.65; 95% CI 0.930-2.981, p = 0.04). In conclusion, kidney transplant recipients did not have an increased incidence of colorectal cancer compared with healthy population. However, transplant patients displayed a higher incidence of colorectal adenomas, suggesting that screening colonoscopy in kidney transplant recipients should be expanded to include even younger recipients (<50 years old).

Quality of Life and Mental Health in Kidney Transplant Recipients During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic has led to an increase in mental distress such as phobic anxieties, depressive reactions, hypochondriac concerns, and insomnia. Among the causes are risk of infection and prolonged isolation. This study aimed to analyze psychopathological variables and dysfunctional lifestyles related to adequate therapeutic compliance in kidney transplant recipients. Methods: Eighty-nine kidney transplant recipients were evaluated using an online protocol including a questionnaire concerning habits, lifestyle and psychophysical well-being in the COVID-19 period, the Middlesex Hospital Questionnaire (MHQ) and the SF-36 Health Survey to evaluate the perception of their physical and emotional health. Results: Of these recipients, 28.6% reported changes in their emotional state. Sleep quality deteriorated for 16.1%. Anxiety (M = 5.57, r = 0.33; p < 0.05) and phobia (M = 6.28, r = 0.26; p < 0.05) correlated with concerns related to physical health. There was no negative impact on relational and socialization aspects, which were likely well compensated by the use of remote technologies such as video phone calls, Zoom meetings and use of computers (r = 0.99; r = 0.80; p < 0.05). Conclusions: It would be interesting to maintain this remote visit and interview mode to monitor, on a clinical and psychological level, kidney transplant recipients in subsequent follow-ups (12-18 months), to check for any psychopathological disorders and/or changes in their resilience capacity in the Coronavirus emergency.

Nipple Sparing Mastectomy as a Risk-Reducing Procedure for BRCA-Mutated Patients.

Growing numbers of asymptomatic women who become aware of carrying a breast cancer gene mutation (BRCA) mutation are choosing to undergo risk-reducing bilateral mastectomies with immediate breast reconstruction. We reviewed the literature with the aim of assessing the oncological safety of nipple-sparing mastectomy (NSM) as a risk-reduction procedure in BRCA-mutated patients. Nine studies reporting on the incidence of primary breast cancer post NSM in asymptomatic BRCA mutated patients undergoing risk-reducing bilateral procedures met the inclusion criteria. NSM appears to be a safe option for BRCA mutation carriers from an oncological point of view, with low reported rates of new breast cancers, low rates of postoperative complications, and high levels of satisfaction and postoperative quality of life. However, larger multi-institutional studies with longer follow-up are needed to establish this procedure as the best surgical option in this setting.

Gastrointestinal complications after kidney transplantation.

Gastrointestinal complications are common after renal transplantation, and they have a wide clinical spectrum, varying from diarrhoea to post-transplant inflammatory bowel disease (IBD). Chronic immunosuppression may increase the risk of post-transplant infection and medication-related injury and may also be responsible for IBD in kidney transplant re-cipients despite immunosuppression. Differentiating the various forms of post-transplant colitis is challenging, since most have similar clinical and histological features. Drug-related colitis are the most frequently encountered colitis after kidney transplantation, particularly those related to the chronic use of mycophenolate mofetil, while de novo IBDs are quite rare. This review will explore colitis after kidney transplantation, with a particular focus on different clinical and histological features, attempting to clearly identify the right treatment, thereby improving the final outcome of patients.

De Novo Cancer Incidence and Prognosis After Kidney Transplantation: A Single Center Analysis.

BACKGROUND: Malignancy is an important cause of mortality in renal transplants recipients. The aim of this study was to evaluate the incidence, prognosis, and survival of patients developing a de novo post-transplant cancer. METHODS: Using a retrospective cohort design, we evaluated the incidence of de novo cancers among kidney transplants patients in our hospital from January 2000 to December 2012. We also evaluated the patient survival after tumor diagnosis. RESULTS: We included 535 kidney transplants recipients with a mean follow-up of 7.8 years; among them, 39 (7.2%) developed malignancies. Median time from transplant to cancer diagnosis was 3 years, with a median age at diagnosis of 60 years. Male patients were significantly older at time of cancer diagnosis (68.5 years) compared with women (38 years, P < .05), and cancer diagnosis occurred significantly earlier in men (3.5 years since transplantation) than in women (8.5 years, P < .05). Among 39 patients affected by a de novo post-transplant cancer, 18 patients (46.2%) died, with an average age at death of 58.5 years. The average time from cancer diagnosis to death was 1.5 years. Among the group of patients who did not develop a post-transplant cancer, 83 patients (16.7%) died, with a median age at time of death of 54.5 years (P < .05). CONCLUSIONS: Kidney transplant recipients are at higher risk of developing a post-transplant cancer. Prognosis after cancer diagnosis is poor, probably as a consequence of a more aggressive behavior of cancer in transplant recipients. Intensive screening protocols could allow for an earlier diagnosis thereby improving the long-term outcome of these patients.

Impact of Incidental Findings During the Evaluation of Live Kidney Donors on Post-Transplant Outcomes: A Single Center Analysis.

BACKGROUND: A careful assessment of a living donor is mandatory to minimize the short- and long-term risk related to kidney donation. In this study, we evaluated the incidence of incidental findings (IFs) in a large population of potential living kidney donors. Moreover, this study evaluated if the presence of IFs could influence the chance of living kidney donation and post-transplant outcomes. METHODS: One hundred and sixty consecutive potential prospective living kidney transplant donors, who underwent a multidetector computed tomography angiography (MDCTA), were included in the study. An IF was defined as an incidentally discovered mass or lesion, detected by computed tomography angiography during the imaging evaluation of potential living donors. Clinical outcomes of living donors with IF were compared with those without IF. RESULTS: In 10 patients (6.2%) an incidental finding was detected at MDCTA assessment. Among the 10 patients presenting with an IF, 7 patients (4.3%) were excluded from the living donation: 2 patients with an adrenal lesion, 3 patients with cancer, and 2 patients with a large (>8 cm) renal cyst. Graft and patient survival of kidney transplant recipients of donors with IFs were not significantly different to those receiving a kidney from living donors without IFs. CONCLUSIONS: Incidental findings are frequently discovered during living kidney donor evaluation. Whereas most are asymptomatic or not clinically relevant, predonation screening could identify potentially life-threatening diseases at an earlier stage, allowing for a more radical treatment.

Conservative management in a case of uncomplicated trap sequence: a case report and brief literature review.

INTRODUCTION: twin reversed arterial perfusion (TRAP) sequence is a rare anomaly that occurs in monochorionic twins with overall mortality rate ranging from 50% to 70% in the normal fetus, above all for congestive cardiac failure. CASE REPORT: a 31-year-old Caucasian gravida was referred to our fetomaternal medicine unit in the 25 gestational age. Ultrasound examination revealed a monochorionic, biamniotic twin pregnancy with a donor fetus showing normal morphology and growth corresponding to gestational age. The recipient twin appeared grossly abnormal with no head, upper limbs, heart, or thoracic structures and massive, diffuse, soft tissue edema. Fetal Doppler and fetal echocardiography revealed normal parameters. The patient refused any treatment and was monitored with weekly ultrasonography and Doppler ultrasound examination. She underwent cesarean section due to premature labor/rupture of membranes secondary to a mild polyhydramnios, at 36 weeks gestational age and delivered an apparent normal female live baby weighing 2550 gr, and another female acardius acephalus twin, birth weight 1300 gr. This baby had rudimental edematous lower limbs, pelvic bone, lower sacral vertebrae, and absence of thorax and cephalic structures. CONCLUSION: although the literature suggest that early intrafetal laser treatment of TRAP sequence is advantageous, our case shows that pregnancies referred late would still require a tailored approach after a risk-benefit assessment.
