Giant parathyroid lipoadenoma case report: A parathyroid phenomenon.

INTRODUCTION: Parathyroid lipoadenomas are a rare parathyroid phenomenon and an unusual cause of primary hyperparathyroidism. A difficult diagnosis to make, there are less than 100 cases in the literature since they were first described in 1958, and to our knowledge this is the largest parathyroid lipoadenoma to be reported. PRESENTATION OF CASE: A minimally-invasive parathyroidectomy with intraoperative parathyroid hormone monitoring was performed in the case of a male with a large neck mass and symptomatic primary hyperparathyroidism. A giant parathyroid lipoadenoma was excised, with an appropriate decrease in intraoperative parathyroid hormone level observed. DISCUSSION: This lesion poses a challenge to the surgeon, radiologist and pathologist alike and is an important addition to the scant literature available. Clinically it presents similarly to a simple adenoma. The high adipose content of this lesion leads to difficulty localising it on imaging, and the histology study can lead pathologists astray. CONCLUSION: We highlight the importance of having the parathyroid lipoadenoma as a differential diagnosis for patients who develop primary hyperparathyroidism.

Acute complicated appendicitis caused by an ingested toothpick - A case report.

INTRODUCTION AND IMPORTANCE: Acute appendicitis is one of the most common presentations to the emergency department, particularly in young adults. A combination of clinical suspicion, inflammatory blood markers and imaging modalities such as ultrasound and CT are used for its definitive diagnosis. Early detection and intervention are paramount to reduce morbidity and mortality. Laparoscopic appendicectomy is the current gold standard in the management of appendicitis, especially if complicated according to EAES guidelines. There are few documented cases in the literature of acute appendicitis secondary to foreign body ingestion. On account of this, there are currently no guidelines for its management. Our literature review highlights the importance of surgical management of foreign body acute appendicitis. CASE PRESENTATION: This case report describes the rare presentation of acute complicated appendicitis caused by an ingested toothpick in a 64 year old woman. The patient was admitted with a 3 day history of lower abdominal pain, localizing to the right iliac fossa with raised inflammatory markers. CT imaging reported acute complicated appendicitis. Laparoscopic appendicectomy was performed during which a toothpick was seen protruding through the appendiceal wall. Post operatively the patient was treated with IV antibiotics for 5 days prior to discharge. CLINICAL DISCUSSION: Due to the rare nature of foreign body appendicitis there are no specific guidelines on the respective surgical approach. A literature review showed that in the setting of foreign body appendicitis, surgical intervention is paramount with no scope for conservative management. CONCLUSION: Surgical approach is based on the clinical judgement and skillset of the operating surgeon.

Association of BMI with Clinicopathological Features of Papillary Thyroid Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Papillary thyroid cancer (PTC) is the most common subtype of thyroid cancer. The incidence of PTC is rising in tandem with an obesity epidemic. Associations have been demonstrated between increased body mass index (BMI) and worse oncological outcomes in a number of malignancies. However, research on this topic in PTC to date has been inconsistent, often due to limited data. This study aimed to measure the association between BMI and potentially adverse clinicopathological features of PTC. METHODS: A meta-analysis of studies reporting outcomes after surgical treatment of PTC was performed. PubMed, Embase and the Cochrane Library were searched systematically to identify studies which provided data on BMI and clinicopathologic features of PTC. Relevant data were extracted and synthesis performed using adjusted odds ratios where available and crude values when not. Data were analysed by inverse variance using random and fixed effects models. RESULTS: Data on 35,237 patients from 15 studies met the criteria for inclusion. Obesity was associated with larger tumour size (MD = 0.17 cm [0.05, 0.29]), increased rates of multifocality (OR = 1.41 [1.16, 1.70]), extrathyroidal extension (OR = 1.70 [1.39, 2.07]) and nodal spread (OR = 1.18 [1.07, 1.30]). Associations were more pronounced as BMI increased. There was no association between BMI and bilaterality, vascular invasion or metastatic spread. CONCLUSION: Increased BMI is significantly associated with multiple potentially adverse features of PTC. The effect on long-term oncological outcomes requires further evaluation.

Breast infections - Microbiology and treatment in an era of antibiotic resistance.

INTRODUCTION: Primary breast abscesses occur in <1% of non-lactating women, rising to 11% in women with lactational mastitis. In patients undergoing breast cancer surgery, the inflammatory response to post-operative surgical site infection (SSI) has been implicated in recurrence. Anti-microbial resistance increasingly hampers treatment in each group. AIMS: Describe the demographic and predisposing characteristics of patients with primary breast abscesses and secondary infections, identify the microbial and antimicrobial patterns and formulate an evidence-based protocol for treating breast infections. METHODS: Retrospective cohort study of all breast infections (primary and post-operative) treated at UHL from 2014 to 2017. Data collected from microbiology databases and patient records was analysed using Minitab V18. RESULTS: 537 cultures from 108 patients were analysed. 47 (43.5%) had primary abscesses, 12 (11.1%) were lactational and 49 (45.4%) were post-operative SSI. For primary infections, the mean age was 41.9 (±12.2) and reinfection rate 33%. For SSIs the mean age was 51.8 (±14.52) and reinfection rate 11.8%. Overall, 29.3% were smokers, 6.4% diabetic and 2.9% pregnant. 60 (43%) patients required radiological drainage and 2 (1%) surgical drainage. 57.5% had mixed growth. The most common isolate was Staphylococcus aureus; cultured in 16.7% of primary abscesses and 24% of SSIs. 13 empiric antibiotic regimes were prescribed before 26.4% of patients changed to 12 different targeted regimes. CONCLUSION: Breast infections are frequently polymicrobial with a wide variety of organisms isolated, suggesting the need for broad spectrum coverage until culture results become available. Based on our local culture results, the addition of clindamycin to flucloxacillin would provide excellent empiric coverage for all categories of breast infection. An evidence-based treatment guideline is required and should be formulated in close collaboration with microbiology specialists.

The impact of hospital grade, hospital-volume, and surgeon-volume on outcomes for adults undergoing appendicectomy.

INTRODUCTION: Acute Appendicitis and appendicectomy are common surgical emergencies worldwide. However, there is a lack of published data on the impact of hospital grade, surgeon- and hospital-volumes on patient outcomes following appendicectomy. AIM: To establish if hospital grade, hospital-volume, or surgeon-volume impacted patient outcomes following appendicectomy. METHODS: Using the National Quality Assurance and Improvement System (NQAIS) data for all appendicectomies performed in Ireland between January 2014 and November 2017 were examined. Data relating to patient demographics, type of surgery (open/laparoscopic/laparoscopic converted to open), length of stay (LOS), mortality, admission to critical care and re-admission rates were collected and analysed. RESULTS: During the study period, 15,896 adult appendicectomies were performed, 14,521 were laparoscopic procedures. Patients treated in district general hospitals (DGHs) had lower LOS (2.96 v 3.37 days, p < 0.0001) than patients treated in tertiary referral hospitals (TRHs), had lower rates of laparoscopic procedures (87.38% v 95.56% p < 0.0001) and higher admission rates to critical care (1.91% v 0.75% p < 0.0001). No significant outcome difference was seen between those treated by high-volume (>62 cases/year) or low volume surgeons (<20 cases/year). Patients treated in high-volume hospitals (>260 cases/year) had higher rates of laparoscopic procedures (94.9% v 83.5%, p < 0.0001), lower rates of admission to critical care (0.85% v 2.25%, p < 0.0001) and lower 7-day re-admission rates (2.54% v 3.55%, p = 0.02) than those operated in low-volume hospitals (<161 cases/year). CONCLUSION: Patients operated on in high-volume hospitals benefit from higher rates of laparoscopic surgery and fewer critical care admissions. No significant difference in outcome was noted in those patients operated upon by high- or low-volume surgeons or based on hospital grade.

Patients' attitude towards travelling for breast services versus waiting longer for local services

Geographical access is a cornerstone of health care provision. However, prolonged waiting for breast clinic appointments in local services results in delayed diagnosis and excessive anxiety for patients. In this study, we present a patient satisfaction survey results of an initiative to offer out-patient clinic appointments for non-urgent patients referred to the breast unit in Letterkenny General Hospital (LGH), Ireland, and exceeded the recommended waiting period of 12 weeks. These patients were offered appointment in University Hospital Galway (UCHG), which is an average travel time of about 3.5-4.5 hours away from LGH. 163 patients out of 336 (48.5%) patients actively waiting more than 12 weeks for appointments in LGH accepted alternative appointments in UCHG. Despite the long travel distance for these patients, 100% of them reported high satisfaction and 97.3% said they would accept further UCHG appointments if a similar situation of prolonged waiting in LGH arises. None of these patients were diagnosed with cancer, and only one had a benign lumpectomy. This study showed that if offered alternative appointments, just under half of the patients would accept. The initiative provides a feasible solution for long waiters, and the survey shows that patients' satisfaction remains high despite long travel.
