Odd Sites of Parathyroid Adenomas: 18F-fluorocholine PET/CT Pointing to the Right Place.

Primary hyperparathyroidism is mostly caused by parathyroid adenoma(s) which are generally localized using routine imaging modalities such as neck ultrasonography and 99mTc-SestaMIBI scintigraphy. However, these can miss ectopic parathyroid adenomas due to their limited sensitivities. These ectopic lesions can later lead to failure of surgical excision and necessitate the need for a re-exploration. 18F-fluorocholine (FCH) positron emission tomography/computed tomography (PET/CT) can help in the localization of these ectopic adenomas due to its superior detection rates and spatial resolution. Herein, we report a case of ectopic parathyroid adenomas that were localized on FCH PET/CT.

Comparison of inflammatory markers in low-pressure pneumoperitoneum with deep neuromuscular block versus standard pressure pneumoperitoneum among patients undergoing laparoscopic cholecystectomy for gallstone disease: a randomized control trial.

BACKGROUND: Low-pressure pneumoperitoneum (LPP) is an attempt to improve laparoscopic surgery. Lower pressure causes lesser inflammation and better hemodynamics. There is a lack of literature comparing inflammatory markers in LPP with deep NMB to standard pressure pneumoperitoneum (SPP) with moderate NMB in laparoscopic cholecystectomy. METHODOLOGY: This was a single institutional prospective randomized control trial. Participants included all patients undergoing laparoscopic cholecystectomy for symptomatic gall stone disease. Participants were divided into 2 groups group A and B. Group A-Low-pressure group in which pneumoperitoneum pressure was kept low (8-10 mmHg) with deep Neuromuscular blockade (NMB) and Group B-Normal pressure group (12-14 mmHg) with moderate NMB. A convenience sample size of 80 with 40 in each group was selected. Lab investigations like CBC, LFT, RFT and serum IL-1, IL-6, IL-17, TNF alpha levels were measured at base line and 24 h after surgery and compared using appropriate statistical tests. Other parameters like length of hospital stay, post-operative pain score, conversion rate (low-pressure to standard pressure), and complications were also compared. RESULTS: Eighty participants were analysed with 40 in each group. Baseline characteristics and investigations were statistically similar. Difference (post-operative-pre-operative) of inflammatory markers were compared between both groups. Numerically there was a slightly higher rise in most of the inflammatory markers (TLC, ESR, CRP, IL-6, TNFα) in Group B compared to Group A but not statistically significant. Albumin showed significant fall (p < 0.001) in Group B compared to Group A. Post-operative pain was also significantly less (p < 0.001) in Group A compared to Group B at 6 h and 24 h. There were no differences in length of hospital stay and incidence of complications. There was no conversion from low-pressure to standard pressure. CONCLUSION: Laparoscopic cholecystectomy performed under low-pressure pneumoperitoneum with deep NMB may have lesser inflammation and lesser post-operative pain compared to standard pressure pneumoperitoneum with moderate NMB. Future studies with larger sample size need to be designed to support these findings.

Combined endovascular and percutaneous approach to the management of spontaneous splenic arteriovenous fistula.

A splenic arteriovenous fistula (AVF) is an uncommon splenic vascular disease which can be congenital or acquired. A 40yr old woman, without any history of chronic liver disease, presented with non-specific pain abdomen, underwent contrast-enhanced CT and was diagnosed to have a splenic AVF with multiple intervening venous aneurysms and early filling of the portal vein. The vascular abnormality was successfully treated with a combined percutaneous glue embolisation and endovascular balloon-assisted coil embolisation. Neither recurrence nor other complications were observed in the patient during the follow-up after 6 months.

Low-pressure pneumoperitoneum with deep neuromuscular blockade versus standard pressure pneumoperitoneum in patients undergoing laparoscopic cholecystectomy for gallstone disease: a non-inferiority randomized control trial.

BACKGROUND: Low-pressure pneumoperitoneum (LPP) is an attempt at improving laparoscopic surgery. However, it has the issue of poor working space for which deep neuromuscular blockade (NMB) may be a solution. There is a lack of literature comparing LPP with deep NMB to standard pressure pneumoperitoneum (SPP) with moderate NMB. METHODOLOGY: This was a single institutional prospective non-inferiority RCT, with permuted block randomization of subjects into group A and B [Group A: LPP; 8-10 mmHg with deep NMB [ Train of Four count (TOF): 0, Post Tetanic Count (PTC): 1-2] and Group B: SPP; 12-14 mmHg with moderate NMB]. The level of NMB was monitored with neuromuscular monitor with TOF count and PTC. Cisatracurium infusion was used for continuous deep NMB in group A. Primary outcome measures were the surgeon satisfaction score and the time for completion of the procedure. Secondarily important clinical outcomes were also reported. RESULTS: Of the 222 patients screened, 181 participants were enrolled [F: 138 (76.2%); M: 43 (23.8%); Group A n = 90, Group B n = 91]. Statistically similar surgeon satisfaction scores (26.1 ± 3.7 vs 26.4 ± 3.4; p = 0.52) and time for completion (55.2 ± 23.4 vs 52.5 ± 24.9 min; p = 0.46) were noted respectively in groups A and B. On both intention-to-treat and per-protocol analysis it was found that group A was non-inferior to group B in terms of total surgeon satisfaction score, however, non-inferiority was not proven for time for completion of surgery. Mean pain scores and incidence of shoulder pain were statistically similar up-to 7 days of follow-up in both groups. 4 (4.4%) patients in group B and 2 (2.2%) in group A had bradycardia (p = 0.4). Four (4.4%) cases of group A were converted to group B. One case of group B converted to open surgery. Bile spills and gallbladder perforations were comparable. CONCLUSION: LPP with deep NMB is non-inferior to SPP with moderate NMB in terms of surgeon satisfaction score but not in terms of time required to complete the procedure. Clinical outcomes and safety profile are similar in both groups. However, it could be marginally costlier to use LPP with deep NMB.

Role of 18Fluorocholine Positron Emission Tomography/Computed Tomography in the Localization of Culprit Lesions in Patients of Persistent/Recurrent Primary Hyperparathyroidism: A Prospective Study in COVID Times.

Introduction: Recurrent/persistent primary hyperparathyroidism in patients who have undergone previous parathyroidectomy is a challenging condition. Imaging is important for localizing the parathyroid adenoma for re-exploration and 18F-Fluorocholine (18F-FCH) positron emission tomography/computed tomography (PET/CT) seems ideal for this purpose. Aim: This prospective study attempted to ascertain the utility of 18F-FCH PET/CT as an investigation in preoperative localization of abnormal parathyroid tissue in recurrent/persistent primary hyperparathyroidism while comparing it with 99mTc-Sestamibi dual-phase scintigraphy with early single-photon emission CT (SPECT)/CT and neck ultrasonography (USG). Methods: Twenty patients with biochemical features of recurrent/persistent primary hyperparathyroidism were enrolled into this study. They underwent neck USG, 99mTc-Sestamibi dual-phase scintigraphy with early SPECT/CT and 18F-FCH PET/CT for localization of parathyroid lesions. Six patients underwent surgical resection of the detected lesions, 3 were awaiting surgery, and 11 were managed conservatively. One patient died due to COVID. Results: The calculated positive predictive values on a per-lesion basis of neck USG, 99mTc-sestamibi scintigraphy and early SPECT/CT and 18F-FCH PET/CT in the cohort of the 5 operated patients were 75% (3/4), 71.4% (5/7), and 71.4% (5/7), respectively. On a per-patient basis, the lesion detection rate was 100% for 99mTc-sestamibi scan and FCH PET (5/5) and 80% on neck USG (4/5). Conclusion: 18F-FCH PET/CT is a highly accurate imaging modality for the detection of parathyroid lesions in patients with recurrent/persistent primary hyperparathyroidism.

Comparison of Neck Ultrasonography, Dual Phase 99mTc-Sestamibi with early SPECT-CT & 18F-Fluorocholine PET-CT as First Line Imaging in Patients with Primary Hyperparathyroidism.

Introduction: Successful surgical treatment for primary hyperparathyroidism requires accurate localization of abnormal parathyroid tissue in terms of location and number. Imaging is important for localizing the parathyroid adenoma, and there has been significant interest in 18F-fluorocholine (FCH) positron emission tomography/computed tomography (PET/CT) for this purpose. Aim: This study attempted to ascertain the utility of 18F-FCH PET/CT as a first-line investigation in preoperative localization of abnormal parathyroid tissue in primary hyperparathyroidism, in comparison with 99mTc-sestamibi dual-phase scintigraphy with early single-photon emission computed tomography (SPECT)/CT and neck ultrasonography. Materials and Methods: Fifty-five patients with biochemical features of primary hyperparathyroidism were enrolled in this study. They underwent neck ultrasonography, 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT, and 18F-FCH PET/CT for localization of parathyroid lesions. Thirty-three patients underwent surgical resection of the detected lesions. For two patients, clinical and biochemical follow-up was used as a gold standard. Results: A total of 40 lesions were resected in the 33 patients who underwent surgery. A further two lesions were localized in two patients with clinical and biochemical follow-up as the gold standard. Of these 42 lesions, 41 were detected in preoperative imaging and 1 lesion was noted intraoperatively and resected. 41/42 lesions were detected by 18F-FCH PET/CT (detection rate: 97.6%), 33/42 by 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT (detection rate: 78.5%), and 30/42 by neck ultrasonography (detection rate: 71.4%). Conclusion: Detection rates on 18F-FCH PET/CT were superior to both 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT and neck ultrasonography in preoperative localization of parathyroid lesions in patients with primary hyperparathyroidism.

Perioperative complications of laparoscopic inguinal hernia repair in India: a prospective observational study.

Purpose: These days laparoscopic inguinal hernia surgery, both totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP), is a commonly performed procedure due to advancements in laparoscopic instruments and the availability of skilled laparoscopic surgeons. The purpose of this study was to compare the perioperative complications of these two procedures. Methods: This was a prospective observational study between July 2019 and December 2020. Perioperative complications were compared with a 6-month follow-up. It included 144 patients, of whom 71 underwent TAPP repair and 73 underwent TEP repair. The selection was based on the surgeon's choice. Results: Early postoperative complications were scrotal edema (12 cases in TEP and 16 in TAPP), urinary retention (one case in TEP), ecchymosis (six cases in TEP and two in TAPP), and scrotal subcutaneous emphysema (two cases in TEP). On follow-up, seroma was found in a total of 22 cases, of which 12 were TEP and 10 were TAPP. While only one case of TAPP developed surgical site infection. There was no statistically significant difference in hospital stay between the two groups (p = 0.58). The pain scores significantly decreased throughout recovery and were comparable between the groups. Neither group experienced a recurrence during the 6-month follow-up. Fifty-eight patients developed Clavien-Dindo grade I complications, one had grade II, and three had grade IIIa complications. Conclusion: With the increasing experience of the surgical fraternity in laparoscopic surgery, TEP and TAPP were proven to be comparable in terms of duration of surgery, postoperative complications, hospital stay, pain scores, and recurrence during the 6-month follow-up.

Macrofollicular Architecture in Invasive Encapsulated Follicular Variant of Papillary Thyroid Carcinoma: A Pitfall in Thyroid Practice.

BACKGROUND: Predominantly macrofollicular architecture in invasive encapsulated follicular variant of papillary thyroid carcinoma (IEFVPTC-MF) is rare and often a cause of misinterpretation during pre-operative work-up and histopathology evaluation. We comprehensively evaluated the radiological, cytological, gross, microscopic, molecular and follow-up characteristics of four such cases, intending to increase its recognition and add our experience to the limited literature available. METHODS: All such histopathologically-proven cases of IEFVPTC-MF were retrieved from the departmental archives. The clinical details, thyroid ultrasound, cytology and thyroid scan findings were reviewed. Allele-specific PCR for BRAF p.V600E, KRAS, NRAS, and HRAS mutations, and FISH assays for ETV6::NTRK3 fusion and RET fusions were performed. RESULTS: There were four cases of IEFVPTC-MF diagnosed between 2021 and 2022, involving two males and two females. The median age at presentation was 27 years, and the duration of the disease was 1-10 years. Thyroid ultrasound was TR1 (benign; n = 1), TR2 (not suspicious; n = 2), or TR4 (moderately suspicious; n = 1). Cytology was categorized as nondiagnostic (n = 1), benign (n = 1), and atypia of undetermined significance (n = 1). The three nodules with available cytology smears showed abundant colloid. Cells were arranged as sheets/microfollicles/clusters. Nuclei were predominantly round with minimal/focal elongation, membrane irregularity, and cellular crowding. On gross examination, cut surfaces of the tumors showed variable amounts of colloid. The tumors were solid-cystic. Histopathology revealed partially encapsulated multinodular tumors. There were prominent pseudopapillae projecting into the lumina of macrofollicles. Nuclei were predominantly round with variable nuclear atypia, including chromatin clearing and multifocal presence of nuclear grooves. Pseudoinclusions were identified in two. Molecular analysis revealed NRAS codon 61 mutation and ETV6::NTRK3 fusion in one case each. Two patients had cervical lymph node and hematogenous metastases. Post-radio-active iodine, the response was structurally incomplete (n = 2), indeterminate (n = 1) and excellent (n = 1). CONCLUSIONS: Macrofollicular architecture in invasive encapsulated follicular variant of papillary thyroid carcinoma is a major pitfall in thyroid oncology practice. Long-standing disease, and ultrasonographic and cytological features that overlap with benign disease, often lead to underdiagnosis during pre-operative evaluation. As patients may consequently develop distant metastases and have inadequate treatment response, there is a need for more vigilant understanding of the spectrum of macrofollicular thyroid disease for accurate diagnosis. ETV6::NTRK3 or other fusions, when found, present opportunities for targeted therapy.

Recurrent Desmoid Fibromatosis of the Thyroid Gland: A Diagnostic Challenge.

A 31-year-old Indian female with a history of near-total thyroidectomy 2.5 years prior presented with recurrent neck swelling. Magnetic resonance imaging (MRI) of the neck revealed an infiltrating mass involving the thyroid bed. Biopsy from the mass and review of slides from the previous thyroidectomy revealed a spindle cell tumour with interspersed areas of fibrosis and infiltrative edges entrapping thyroid follicles. Beta-catenin immunopositivity and CTNNB1 mutation confirmed the diagnosis of fibromatosis. The case is being reported for its rarity and the discussion of its differential diagnoses.

Multi-modality parathyroid imaging: A shifting paradigm.

The goal of parathyroid imaging in hyperparathyroidism is not diagnosis, rather it is the localization of the cause of hyperparathyroidism for planning the best therapeutic approach. Hence, the role of imaging to accurately and precisely localize the abnormal parathyroid tissue is more important than ever to facilitate minimally invasive parathyroidectomy over bilateral neck exploration. The common causes include solitary parathyroid adenoma, multiple parathyroid adenomas, parathyroid hyperplasia and parathyroid carcinoma. It is highly imperative for the radiologist to be cautious of the mimics of parathyroid lesions like thyroid nodules and lymph nodes and be able to differentiate them on imaging. The various imaging modalities available include high resolution ultrasound of the neck, nuclear imaging studies, four-dimensional computed tomography (4D CT) and magnetic resonance imaging. Contrast enhanced ultrasound is a novel technique which has been recently added to the armamentarium to differentiate between parathyroid adenomas and its mimics. Through this review article we wish to review the imaging features of parathyroid lesions on various imaging modalities and present an algorithm to guide their radiological differentiation from mimics.

Endoscopic totally extraperitoneal repair for groin hernia: Experience from a tertiary care centre.

Background: Totally extra-peritoneal (TEP) and transabdominal preperitoneal (TAPP) repair are two established minimal access techniques of groin hernia surgery. TEP offers the advantage of avoiding violation of the peritoneal cavity. Aim: This study aims to describe the decade-long experience of TEP in groin hernia repair in a tertiary care teaching institute and the feasibility of the same in difficult scenarios. Materials and Methods: Retrospective analysis of the database of patients undergoing TEP repair for inguinal hernia in a single surgical unit at a tertiary teaching hospital between January 2008 and December 2019 was performed. Detailed pre-operative clinical details, operative duration, intraoperative and post-operative complications, including pain, length of post-operative hospital stay and hernia recurrence data were analysed. Results: Over 12 years' duration, 511 patients underwent endoscopic TEP mesh repair and the total number of hernias repaired was 614. Majority (97.45%) of patients were male. The mean age of the patient population was 51.3 years. Primary hernia was seen in 490 patients. The mean operating time for unilateral inguinal hernia repair was 56.8 ± 16 min and for bilateral repair 80.9 ± 25.2 min. TEP in previous lower abdominal/suprapubic surgical scars was attempted in 17 (3.3%) patients, with only one requiring conversion. The intraoperative peritoneal breach was the most common documented complication (34.8%). Seroma was seen in 9.4% of patients. Seventeen patients required conversion (14 TAPP and 3 open). Recurrence was seen in 4 (0.7) patients. Conclusion: TEP repair is an effective method of groin hernia repair and can be attempted in the majority of patients groin hernia, including patients with previous lower abdominal incisions.

Impact of Fluoro-Choline PET/CT in Reduction in Failed Parathyroid Localization in Primary Hyperparathyroidism.

INTRODUCTION: Accurate localization of the pathological parathyroid gland is a prerequisite for minimally invasive surgical management of hyperparathyroidism (HPT). Poor imaging or discordance in odd situations like ectopic adenomas, parathyroid hyperplasia, syndromic HPT results in localization dilemma thus causing failed parathyroidectomy. We studied the impact of Fluoro-Choline (FCH) PET/CT imaging in reduction in localization failure of parathyroid adenoma. MATERIALS AND METHODS: We did a retrospective observational study (2018-2021) of HPT among which 97 patients underwent focused parathyroidectomy (FP). All patients had undergone ultrasound imaging and 99mTc-sestaMIBI scan with early SPECT/CT (MIBI). When this preliminary imaging was doubtful or negative or multiple lesions were expected, FCH PET/CT was performed. We compared the localization accuracy of MIBI scan and FCH PET/CT with surgical outcomes as reference standard. RESULTS: MIBI scan showed overall lesion detection rate (LDR) of 88.65% in localization of pathological parathyroid gland in 97 patients. The addition of FCH PET/CT improved the overall lesion detection to 97.9%. The overall possible localization failure was reduced from 11.34 to 2.06% with the addition of FCH PET/CT (p < 0.05). Out of 97 patients of FP, 87 patients showed features of parathyroid adenoma. Single hyperplastic gland was seen in 7 patients, lipoadenoma was seen in 1 patient and 1 patient had features suggestive of parathyroiditis on histopathology. FCH PET/CT was a useful adjunct and showed significant reduction in localization failure of parathyroid adenoma.

Illness wellness scale: novel grading system for performance status of patients under surgical care.

BACKGROUND: Grading the illness using clinical parameters is essential for the daily progress of inpatients. Existing systems do not incorporate these parameters holistically. The study was designed to internally validate the illness wellness scale, based upon clinical assessment of the patients requiring surgical care, for their risk stratification and uniformity of communication between health care providers. METHODS: Prospective observational study conducted at a tertiary care hospital. An expert panel devised the scale, and it was modified after feedback from 100 health care providers. A total of 210 patients (150 for internal validation and 60 for inter-observer variability) who required care under the department of surgical disciplines were enrolled. This included patients presenting to surgery OPD, admitted to COVID/non-COVID surgical wards and ICUs, aged ≥16 years. RESULTS: The response rate of the final illness wellness scale was 95% with 86% positive feedback and a mean of 1.7 on the Likert scale for ease of use (one being very easy and five being difficult). It showed excellent consistency and minimal inter-observer variability with the intra-class correlation coefficient (ICC) above 0.9. In the internal validation cohort (n = 150), univariate and multivariable analysis of factors affecting mortality revealed that categorical risk stratification, age ≥ 60 years, presence or absence of co-morbidities especially hypertension and chronic kidney disease significantly affect mortality. CONCLUSIONS: The Illness wellness scale is an effective tool for uniformly communicating between health care professionals and is also a strong predictor of risk stratification and mortality in patients requiring surgical care.

Gastric Outlet Obstruction Following Recurrent Pancreatitis Uncovers a Giant Parathyroid Adenoma: A Case Report.

A 35-year-old female presented with abdominal pain, fever, projectile vomiting, and a diffuse tender epigastric mass. She was diagnosed to have acute persistent pancreatitis with a pancreatic pseudocyst. Elevated serum calcium levels provided an etiologic link between hypercalcemia and pancreatitis. On examination, a nodule was found in the left side of her neck which was later diagnosed as a giant left inferior parathyroid adenoma. This report highlights the critical analysis of history, examination, and investigations to reach an ultimate diagnosis. Pseudocyst drainage and parathyroidectomy resolved her symptoms.

Laparoscopic management of type VI choledochal cyst with common bile duct stone: report of a case and review of literature.

A young adult male presented with biliary colic and intermittent jaundice for 1 year. Abdomen findings were unremarkable. Routine investigations revealed a raised total bilirubin. On abdominal ultrasonography, common bile duct (CBD) dilatation with multiple stones was noted. On further imaging with magnetic resonance cholangiopancreatography, type I choledochal cyst (CDC) was suspected. A laparoscopic approach was planned. Intraoperatively, dilatation of cystic duct was noted which constitute type VI CDC. Partial malrotation of the gut and accessory right hepatic artery were also noted as incidental finding. Laparoscopic cholecystectomy with CBD exploration and removal of stones, biliary stent placement, cystic duct cyst excision and primary repair of CBD was done. Postoperatively, the patient improved symptomatically with a fall in bilirubin to normal range. We are describing the laparoscopic management of a rare case of type IV CDC which was diagnosed intraoperatively.

Comparison of Non-Operative Mesotherapy and Surgery in the Management of Superficial Lipomas.

BACKGROUND: Lipomas are benign adipocytic tumours. Surgical excision is the gold standard for treating such lipomas, but it results in unaesthetic scarring. METHODS: A total of 126 patients were randomised into two groups. The patients in Group A underwent mesotherapy (n = 66) and those in Group B underwent surgery (n = 60). The patients in Group A group received six sessions of mesotherapy treatment at 2-week intervals. Both groups were followed up for 12 weeks, during which they were assessed for complications arising from treatment, reduction of the size of the lipoma and cosmetic outcomes. RESULTS: The overall mean age of the patients was 32.93 (± 10.1) years old and the mean volume of the lipomas was 2.29 (± 3.8) mL. A 55.86% (P = 0.0032) mean reduction in the volume of lipomas was noted in the patients who received mesotherapy, while one patient showed a gain of 16% by volume. The patients in Group A (cosmetic score ≥ 4: 63%) were happier with the treatment than those in Group B (cosmetic score ≥ 4: 21%). CONCLUSION: Our findings indicate that mesotherapy modestly reduces the volume of lipomas with very few and minor complications and excellent cosmetic outcomes.

CT-Guided Lumbar Sympathectomy as a Last Option for Chronic Limb-Threatening Ischemia of the Lower Limbs: Evaluation of Technical Factors and Long-Term Outcomes.

OBJECTIVE. The purpose of this study was to assess the effects of anatomic and technical factors on the long-term outcome of CT-guided lumbar sympathectomy in patients with chronic limb-threatening ischemia. SUBJECTS AND METHODS. Thirty patients (28 men, two women; mean age, 45.8 years) with chronic limb-threatening ischemia and diffuse tibial arterial disease not amenable to revascularization were included. CT-guided lumbar sympathectomy was performed at the L2-L3 level with a 22-gauge Chiba needle and absolute alcohol. Any periprocedural complication was noted. Numeric pain score (1-10 scale) and skin ulcers were assessed before the procedure and 3 weeks, 3 months, and 1 and 2 years after the procedure. According to spread of alcohol, patients were categorized into those with medial spread and those without medial spread (lateral spread group) with the lateral edge of the vertebral body as the reference point. Treatment results were categorized as improved, unchanged, or worsened on the basis of clinical response. RESULTS. There were 22 (73.3%) patients in the medial spread group and eight (26.7%) in the lateral spread group. The mean volumes of alcohol injected per side were not significantly different (p = .50). One major complication occurred in the group with medial spread. Mean numeric pain scores before the procedure and 3 weeks, 3 months, and 1 and 2 years afterward were 7.31, 2.95, 2.47, 2.10, and 2.04 in the medial spread group and 6.25, 4.13, 4.50, 4.35 and 4.32 in the lateral spread group (p < .001). At 2 years, 16 patients in the medial spread group and two patients in the lateral spread group showed clinical improvement (p < .001), and the limb salvage rates were 100% and 87.5%, respectively. Multivariate analysis showed a trend in improvement with smoking cessation, but the difference was not statistically significant (p = .15). The direction of spread of the neurolytic agent, however, was a major determinant of outcome. CONCLUSION. CT-guided lumbar sympathectomy is a simple, safe, and effective procedure. Ensuring medial spread of the neurolytic agent significantly improves long-term results.

Giant secretory multifocal adrenal myelolipoma: a diagnostic dilemma.

A 38-yearr-old man presented with erectile dysfunction and infertility. On examination, he was hypertensive and detected to have a left flank mass. Blood investigations were unremarkable except raised serum noradrenaline levels. Imaging revealed multiple well-defined fat-containing hypodense lesions in left suprarenal area with largest one measuring 14×16 cm, suggestive of left adrenal myelolipoma. Diagnostic dilemma was posed due to discordance between clinical, biochemical and imaging findings. Left adrenal mass resection was planned keeping the possibility of pheochromocytoma. However, histopathology revealed it to be adrenal myelolipoma. Hypertension was resolved in the postoperative period and serum noradrenaline levels were normalised. Final diagnosis of a secretary adrenal myelolipoma was made, which is an extremely rare entity.

An Analysis of the Economic Burden of the Trauma Services at a Level 1 Public Sector Trauma Center in South Asia.

BACKGROUND: Incidence of road traffic injuries (RTIs) is increasing and accounting for country's 3% gross domestic product. It is crucial to perform a cost analysis of trauma systems to allocate resources judiciously. AIM AND OBJECTIVES: To study the economic burden of trauma care on the patient attending a level I trauma center including stratification of costs according to injury. MATERIALS AND METHODS: This is a prospective study, with patients of polytrauma (Injury Severity Score >16) admitted in the center. Cost analysis (cost descriptive study) was done by calculating direct costs to hospital by bottom-up microcosting considering fixed and recurrent costs including reference unit prices (RUPs). According to the anatomical site of injuries, major injury groups (MIGs) costs were also analyzed. RESULTS: The demographics including mode of injury were similar to other studies. The RUP's and MIG's were defined which represented majority of the sample size. Due to highly subsidized nature of services in this Government institute, the cost to patient is less compared to other countries. Still, the total expenditure incurred by the low-income group was higher than the minimum wages at that time. The creation of plausible RUP's and the grouping of MIG's can help in reducing the costs by targeting and implementing strategic cost reduction measures. CONCLUSION: The study has shown that microcosting is feasible. Considering the low-income population demanding trauma services, further efforts are required to reduce costs substantially.
