Prognostication for recurrence patterns after curative resection for pancreatic ductal adenocarcinoma.

Backgrounds/Aims: This study aimed to investigate patterns and factors affecting recurrence after curative resection for pancreatic ductal adenocarcinoma (PDAC). Methods: Consecutive patients who underwent curative resection for PDAC (2011-21) and consented to data and tissue collection (Barts Pancreas Tissue Bank) were followed up until May 2023. Clinico-pathological variables were analysed using Cox proportional hazards model. Results: Of 91 people (42 males [46%]; median age, 71 years [range, 43-86 years]) with a median follow-up of 51 months (95% confidence intervals [CIs], 40-61 months), the recurrence rate was 72.5% (n = 66; 12 loco-regional alone, 11 liver alone, 5 lung alone, 3 peritoneal alone, 29 simultaneous loco-regional and distant metastases, and 6 multi-focal distant metastases at first recurrence diagnosis). The median time to recurrence was 8.5 months (95% CI, 6.6-10.5 months). Median survival after recurrence was 5.8 months (95% CI, 4.2-7.3 months). Stratification by recurrence location revealed significant differences in time to recurrence between loco-regional only recurrence (median, 13.6 months; 95% CI, 11.7-15.5 months) and simultaneous loco-regional with distant recurrence (median, 7.5 months; 95% CI, 4.6-10.4 months; p = 0.02, pairwise log-rank test). Significant predictors for recurrence were systemic inflammation index (SII) ≥ 500 (hazard ratio [HR], 4.5; 95% CI, 1.4-14.3), lymph node ratio ≥ 0.33 (HR, 2.8; 95% CI, 1.4-5.8), and adjuvant chemotherapy (HR, 0.4; 95% CI, 0.2-0.7). Conclusions: Timing to loco-regional only recurrence was significantly longer than simultaneous loco-regional with distant recurrence. Significant predictors for recurrence were SII, lymph node ration, and adjuvant chemotherapy.

Intraoperative acute compartment syndrome of the upper limb secondary to extravasation.

A woman in her 50s was undergoing a repeat liver resection surgery for recurrence of liver metastasis when the intravenous fluid flow was noted to be sluggish on multiple occasions. On the third examination of the right hand where the intravenous cannula was located, surgery was halted as there was extensive swelling from the hand to the biceps and the hand had started turning blue. A diagnosis of acute upper limb compartment syndrome secondary to extravasation exacerbated by metaraminol was made by the anaesthetist and surgeon. Fasciotomies of the right upper limb were performed, and perfusion was restored. A hand surgeon arrived shortly after and completed decompressing the upper limb compartments.A literature review revealed risk factors such as communication barriers, age and chemotherapy were present in this case. Enhanced monitoring is needed in the context of unsatisfactory infusion flow rates perioperatively.

Large desmoid tumour of the small bowel mesentery.

A 74-year-old man was being investigated for a pancreatic insulinoma when an incidental mesenteric mass measuring 2.6 cm x 2.5 cm was noticed on CT imaging. A wait-and-see approach was decided on. Thirty-nine months later, the patient presented with symptoms of abdominal obstruction. CT images revealed the mesenteric mass filled majority of the abdominal cavity and measured 29 cm x 26 cm x 16 cm. The patient underwent an open bypass gastrojejunostomy which stopped working a few weeks later due to further compression by the tumour. A debulking surgery was performed: a right hemicolectomy and small bowel resection with excision of the desmoid tumour and bypass gastrojejunostomy. The tumour measured 12.6 kg and was macroscopically visualised to have a white cut surface with a focal translucent area. Microscopic analysis revealed bland spindle cells with pale eosinophilic cytoplasm showing no cytological atypia, in keeping with a mesenteric desmoid tumour. Currently, two and a half years from the debulking surgery, the patient remains well and in remission with planned surveillance.

Assessing the preparedness of foundation year 1 (FY1) doctors during the transition from medical school to the foundation training programme.

BACKGROUND: To assess how ready current FY1 doctors felt when starting their first posting as newly qualified doctors. METHODS: We created an online survey where 45 FY1 doctors in South Yorkshire rated how confident they were across different domains (Induction and Assistantship, Hospital Systems, and Skills) using a scale ranging from 0 (no confidence performing task) to 5 (highly confident). RESULTS: The ICE system and observations had a mean rating of 3.645 (95% CI 3.446 to 3.844), and 4.425 (95% CI 4.248 to 4.602) with a standard deviation (SD) of 1.10 and 0.83 respectively. The radiological platform, referral system, telephone system, and hospital notes had a mean score of 3.149 (95% CI 2.876 to 3.422), 2.340 (95% CI 2.096 to 2.584), 3.573 (95% CI 3.407 to 3.739) and 4.061 (95% CI 3.931 to 4.191), with a SD of 1.281, 1.153, 0.961 and 0.752 respectively. Patient needs and diagnostic procedures had a mean score of 3.933 (95% CI 3.749 to 4.117) and 4.250 (95% CI 4.140 to 4.360) with a SD of 1.190 and 0.944 respectively. Patient care, prescribing, and therapeutic procedures gave a mean score of 3.634 (95% CI 3.432 to 3.836), 4.130 (95% CI 3.959 to 4.301), 3.386 (95% CI 3.228 to 3.544) with a SD of 1.133, 0.958 and 1.256 respectively. No statistically significant difference in the overall mean score was found between respondents who attended medical schools in Yorkshire, and those who had not. CONCLUSION: Overall, confidence differs across different domains and categories. A larger sample size across a wider geographical area would allow us to compare and contrast results across the different regions in the UK.

Paternity seven years after a negative post-vasectomy semen analysis: a case report.

BACKGROUND: Vasectomy is one of the permanent methods of contraception; however, the risk of conception still exists. Early failure, defined as a postoperative semen analysis showing persistent motile sperm, occurs in 1 in every 250 patients. Late failure, defined as the rejoining of the severed ends of the vas deferens, occurs in 1 in every 2000 patients. CASE PRESENTATION: A healthy 37-year-old British male presented to our clinic because his wife had conceived seven years after he had undergone a vasectomy. The result of his semen analysis after the vasectomy was negative, and the histopathological report confirmed that the sample contained tissue from both the left and right vas deferens. His wife conceived seven years after the procedure, and semen analysis at that time confirmed a total of 0.5 million sperm per milliliter of semen in a total semen sample of 6.3 ml. The total number of motile sperm recorded was 2.5 million. CONCLUSION: This case shows that late recanalization can occur up to seven years after a vasectomy. Patients should be informed prior to the procedure that late recanalization, although rare, may still occur. Post-vasectomy paternity necessitates further counseling to ensure that the patient and the patient's partner fully understand the implications and options available to them.

Depression, anxiety and acute pain: links and management challenges.

Pain is a subjective experience that is influenced by genetics, gender, social, cultural and personal parameters. Opposed to chronic pain, which by definition has to last for at least 3 months, acute pain is mostly because of trauma, acute medical conditions or treatment. The link between mood disorders and acute pain has proven to be increasingly significant since the link is bi-directional, and both act as risk factors for each other. Depression and anxiety are associated with increased perception of pain severity, whereas prolonged duration of acute pain leads to increased mood dysregulation. Although both depression and anxiety have a proven association with acute pain, the link between depression and acute pain is more thoroughly studied. Pain can be the presenting or sole complaint in depressed patients who present to primary care practices and is often overlooked by clinicians. However, reports on the perception of experimentally-induced pain in depressed patients are mixed, showing both an increased and decreased pain threshold and pain tolerance across various studies. Although less data is published about anxiety and pain, the relationship is consistent across studies as increased anxiety leads to increased severity of pain perceived and decreased pain tolerance. Anxiety as well as fear, stress, and catastrophizing are also shown to be mediators in the causal pathway between pain and disability.

Pain in Chronic Inflammatory Demyelinating Polyradiculoneuropathy: A Systematic Review and Meta-Analysis.

INTRODUCTION: Although chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) predominantly affects large myelinated fibers, many patients have pain. The aim of this paper is to systematically review the current literature regarding CIDP with a particular focus on epidemiological and clinical characteristics of painful CIDP. METHODS: A systematic literature search was conducted on PubMed database. RESULTS: Our search strategy identified 146 articles. Thirty-eight papers, reporting on 991 patients, met the inclusion criteria and were used for this review. The pooled estimate of the prevalence of pain at any point within the course of CIDP was 46% (95% CI 36-57%). Immune treatment of CIDP might be adequate as monotherapy for the management of pain. Treatment specific to pain currently shows effectiveness as adjuvant treatment when CIDP is treated and pain persists. CONCLUSIONS: Pain in CIDP is an underexplored field. Future research should focus on the natural history, phenomenology, and management of pain in CIDP.
