Laparoscopic Versus Open Surgical Management of Hydrocele of the Canal of Nuck: A Retrospective Analysis of 20 Cases

INTRODUCTION

 Hydrocele of the canal of Nuck is a condition that arises due to incomplete obliteration of the processus vaginalis or an abnormal outpouching from the round ligament during fetal development. It usually presents as a painless, rarely painful, groin swelling. The definitive diagnosis for this condition is magnetic resonance imaging. Various management options have been proposed for this condition, including open surgery, transabdominal preperitoneal approach, totally extraperitoneal approach, and a combination of laparoscopic and open surgery. The present study highlights the benefits of the transabdominal preperitoneal approach when compared with the open anterior approach and addresses the intraoperative challenges faced during laparoscopic surgery.

MATERIALS AND METHODS

 The study is a retrospective study inclusive of 20 patients who underwent surgery for the hydrocele of the canal of Nuck from June 2019 to December 2023. Case records of patients were studied for information such as demographic features, type of pathology, the surgery performed, intraoperative challenges encountered, operative time, duration of hospital stay, scores from the visual analog scale pain assessment chart at various intervals, and time taken to return to work. The variables were documented and statistically analyzed.

RESULTS

 The average age group of the study population was 27.8 ± 8.34 years. Of the 20 patients, 10 had undergone a transabdominal preperitoneal approach (Group A), and 10 had undergone an open anterior approach (Group B). Eleven out of 20 patients had an associated inguinal hernia, of which three were identified preoperatively and eight were identified incidentally during surgery. The mean operative time of Group A cases was 97.95 ± 7.54 minutes, while it was 66.3 ± 6.20 minutes for Group B cases. The Mann-Whitney U test showed a statistically significantly lesser operative time for Group B than for Group A (p-value < 0.001). The duration of hospital stays was comparable for the two groups with no significant difference (two days versus 3.8 ± 3.08 days, respectively). When the difference in the means of time taken to return to normal work was compared using the Mann-Whitney U test between Group A and B (6.1 ± 0.87 days and 11.2 ± 1.81 days, respectively), a statistically significant early return to normal work in the former group (p-value = 0.001) was revealed. Similarly, the Mann-Whitney U test when used to compare the median postoperative pain score of both groups at 12-24 hours, 48-72 hours, seven days, and three months showed a significantly lesser pain score among patients of Group A at all intervals (p-value < 0.001, p-value = 0.005, p-value = 0.005, p-value < 0.001, respectively). The incidence of intraoperative challenges, sero-hematoma, and surgical site infection were insignificant in comparison.

CONCLUSION

The transabdominal preperitoneal approach for the hydrocele of the canal of Nuck is ideal as it offers excellent intraoperative delineation of pathology and postoperative outcomes. Prophylactic placement of a mesh in all cases can help prevent a future occurrence of inguinal hernia in these cases.

Primary Closure Versus Delayed Primary Closure of Class III and IV Surgical Wounds Following Emergency Laparotomy: A Prospective Comparative Study

Introduction Emergency surgery has a high risk of complications due to the detrimental effect of perioperative sepsis and the relative lack of preoperative optimization of patients. Despite advances in critical care for the management of sepsis, its prevention is dependent on various patient and surgeon factors. Surgical site infection continues to be a major determinant of morbidity and mortality following emergency abdominal surgery, especially in contaminated or dirty wounds. This study aims to compare two techniques of abdominal wall closure, primary closure with subcutaneous suction drains and delayed primary closure following negative pressure wound therapy, in terms of incidence of surgical site infection and morbidity. Materials and methods The study was a prospective comparative study including 50 patients with an acute surgical abdomen requiring laparotomy. The patients were randomized into two groups, Group A (n=25) who underwent primary closure, and Group B (n=25) who underwent delayed primary closure. In Group B patients, a vacuum-assisted closure device was applied in the subcutaneous space for five days prior to the closure of the skin. Outcomes were compared in terms of the incidence of superficial and deep surgical site infection, its association with diabetes mellitus, and the total duration of hospital stay. A chi-square test and an unpaired t-test were used for the test of significance. Results A total of 50 patients, comparable in age, were included in the study. The overall incidence of surgical site infection was significantly higher in patients of Group A as compared to Group B (p=0.0046). There was a positive correlation between diabetes mellitus and the occurrence of wound infection in both groups with the odds ratio being 2.67 and 2.38 respectively. The incidence of superficial wound infection was significantly higher in Group A when compared to Group B (52% versus 24%; p=0.04). Deep surgical site infection was higher in patients of Group A (20% versus 8%) but was not statistically significant (p=0.22). The average duration of hospital stay was 41.56 ± 6.96 and 37.86 ± 6.68 days for patients who developed complications from Groups A and B respectively, while it was nearly two and a half times lower in uncomplicated cases of Groups A and B (11.71± 1.70 days and 16.58± 1.06 days respectively). The one-tailed unpaired t-test showed a significant difference in means of hospital stay between patients with and without complications (T: 17.06, critical value: 1.677). Conclusion Delayed primary closure is an effective method of managing contaminated and dirty wounds following emergency laparotomy. Negative pressure wound therapy is one technique for preventing wound bed infection and accelerating wound healing in such cases. By combining the above in emergency surgeries, the incidence of surgical site infection and duration of hospital stay can be significantly reduced.

A Para-Scrotal Pleomorphic Liposarcoma Mimicking As Another Scrotum (Pseudo-Scrotum): A Case Report

Liposarcomas are a subtype of soft tissue sarcomas arising from lipoblasts, a mesenchymal cell lineage that commonly arises from deep tissues of the body. Though these are the most common subtypes, their early diagnosis still remains a challenge due to their varied presentation as a soft benign appearing growth. The pleomorphic variant has complex management due to its high recurrence rate and resistance to chemoradiation. Scrotal liposarcomas have been reported. But in the present case, a 69-year-old male who presented with a pedunculated swelling in the left groin mimicking a left hemi-scrotal swelling. It was a left para-scrotal pleomorphic liposarcoma which was totally extra-scrotal, and not related to the spermatic cord or testes. So, this is a rare case with a review of the literature presented here.

AB0148 COULD THE RENIN-ANGIOTENSIN SYSTEM AFFECT THE PROGNOSIS OF GIANT CELL ARTERITIS? SINGLE-CENTRE RETROSPECTIVE OBSERVATIONAL STUDY

Background

About half of patients with giant cell arteritis (GCA) relapse while tapering glucocorticoid therapy1. A previous observational study reported that blockade of the renin-angiotensin system, with angiotensin II receptor blockers (ARBs), was associated with lower relapse risk2.

Objectives

To determine whether angiotensin blockade, with angiotensin converting enzyme inhibitor (ACEi) or ARB, is associated with differential relapse risk in GCA.

Methods

GCA patients from a tertiary centre diagnosed 2012–2020 with two years follow-up were identified from UK GCA Consortium. All provided written informed consent. Retrospective review of medical records included demographics, comorbidities, drug history, inflammatory markers and relapses. Relapse was defined as return of symptoms, raised inflammatory markers, or active vasculitis on imaging confirmed by the treating clinician. Relapse-free survival was analysed using Kaplan Meier (KM) curves and Cox proportional hazards.

Results

111 patients were included (Table 1: demographic data), all were initially treated with 40–60mg Prednisolone. 42% received further immunosuppressants due to relapse or disease severity. 50% patients relapsed in two years, presenting with cranial symptoms (72%), PMR-like symptoms (30%) and/or raised inflammatory markers (48%). There was no association between relapse and age, gender, comorbid HTN/IHD or pre-steroid inflammatory markers and relapse. Rate of steroid taper can affect relapse. EULAR recommend 15–20mg of steroid by three months3. 9 patients relapsed within that time and were excluded, there was no difference in steriod dose at three months between the two groups. KM analysis showed ACEi did not significantly affect time to relapse compared to no angiotensin blockade (HR 0.57, 95% CI 0.28 – 1.18, unadjusted p-value=0.128), and neither did an ARB (HR 0.78, 95% CI 0.31 – 1.98, unadjusted p-value=0.605).

There was no significant difference in relapse free survival in patients on an ACEi compared to those taking neither ACEi or ARB.

Conclusion

In the two years following GCA diagnosis 50% relapsed. There was no significant difference in the rate of relapse in patients taking an ACEi or ARB. The main limitation, in this retrospective, observational study was the inability to exclude a reluctance of clinicians to diagnose GCA relapse in the presence of cardiovascular comorbidity. A randomised controlled trial would be needed to determine whether starting an ACEi could reduce relapse risk in patients with new-onset GCA.

Performance of 3 mL versus 5 mL Discarded Volume for Blood Sampling from Central Venous Access Device

Background  Central venous access devices (CVAD) are an essential part of safe practices in critical care, which enable effective venous access and help in avoiding repeated venipuncture. Discard method is widely practiced for blood sampling. A single occasion of blood sampling may cause minimal blood loss; however, the cumulative volume sequential sampling may become clinically significant. The study aims to reduce diagnostic blood loss, ensuring that the subsequent blood sample is not diluted or contaminated by residual intraluminal fluid. Patients and Methods  Within-subjects comparative design was adopted for 64 adult patients in the medical intensive care unit of a tertiary hospital. Two blood samples, using 3 mL and 5 mL discarded volume methods, were collected from each patient. Six serum parameters were measured on each of the paired samples and compared. Statistical Analysis Used  Paired t -test and Wilcoxon signed rank test were used for comparing the two methods. Bland-Altman plot analysis and intraclass correlation were used for clinically meaningful analysis. Results  When tested for fixed bias, there is no statistically significant difference between the methods. Potassium and creatinine levels showed significant proportional bias. The agreement limits of sodium, potassium, creatinine, and direct bilirubin were outside the clinically accepted interval, but the proportion of samples outside these intervals was less than 10%. All serum parameters showed excellent reliability, except for sodium which demonstrated good reliability. Conclusions  The practice of discarding 3 mL of blood for discard method is suggested, instead of the standard 5 mL to reduce iatrogenic blood loss. Thus, nurses in critical care are uniquely positioned to limit the diagnostic blood loss while obtaining blood samples.

Heart-lung transplantation for idiopathic pulmonary arterial hypertension and giant pulmonary artery aneurysm - case report

Backgound

Idiopathic pulmonary arterial hypertension (IPAH) is a rare condition that requires lung transplantation in patients’ refractory to medical therapy. Pulmonary artery aneurysm (PAA) is a documented complication of IPAH however, optimal management and timing of intervention for this rare entity is not well understood.

Case report

We report a case of a 51-year-old female who underwent heart-lung transplantation for IPAH and giant PAA. The extreme size of the PAA and underlying pathology encountered in this case precluded both lung transplantation and conventional aneurysm repair.

Conclusion

This case demonstrates that heart-lung transplantation is a good surgical option for IPAH complicated by giant sized PAA and right heart failure.

Adjunctive aripiprazole in risperidone-induced hyperprolactinaemia: double-blind, randomised, placebo-controlled trial

BACKGROUND

Hyperprolactinaemia is a troublesome side-effect of treatment with antipsychotics.

AIMS

This double-blind, placebo-controlled study aimed at examining the effect of adjunctive treatment with 10 mg aripiprazole on prolactin levels and sexual side-effects in patients with schizophrenia symptomatically maintained on risperidone.

METHOD

Thirty patients taking risperidone were enrolled into the trial (CTRI/2012/11/003114). Aripiprazole was administered at a fixed daily dose of 10 mg/day for 8 weeks. Serum prolactin was measured at baseline and at 8 weeks. Hyperprolactinaemia-related problems, psychopathology and side-effects were evaluated every 2 weeks.

RESULTS

Prolactin levels decreased by 58% in the aripiprazole group compared with an increase by 22% in the placebo group. Prolactin levels normalised in 46% of patients in the aripiprazole group (number needed to treat, NNT=2). Aripiprazole improved erectile dysfunction in five out of six patients. There were no significant differences in change in psychopathology or side-effects between groups.

CONCLUSIONS

Adjunctive aripiprazole reduced prolactin levels in those treated with risperidone, with no effect on psychopathology and extrapyramidal symptoms. This is a potential treatment for hyperprolactinaemia observed during treatment with second-generation antipsychotics.

A Motorized Microdrive for Recording of Neural Ensembles in Awake Behaving Rats

The recording of neural ensembles in awake, behaving rats has been an extremely successful experimental paradigm, providing demonstrable scientific advances. Dynamic control of the position of the implanted electrodes is of key importance as mobile electrodes provide a better signal-to-noise ratio and a better cell/electrode yield than nonmobile electrodes. Here we describe the use of low cost, soon to be commercially available dc motors to successfully control the depth of electrodes. The prototype designed is approximately 30mm in diameter and 50mm in length and weighed about 30gms. This paper presents the results of linear displacements of electrodes achievable with this motorized microdrive.

Childhood iron deficiency anemia, maternal nutritional knowledge, and maternal feeding practices in a high-risk population

BACKGROUND

Despite the proven success of national efforts such as the Special Supplementary Food Program for Women, Infants, and Children (WIC) to curb childhood iron deficiency anemia (IDA) in the United States, aggregate programmatic data may not accurately represent the experience of particularly high risk groups, such as the children of adolescent mothers of low socio-economic status.

METHODS

This study evaluated the prevalence and severity of childhood anemia and associated risk factors, at one urban teen health center serving primarily low-income adolescent mothers and their children. A total of 175 pediatric WIC charts were reviewed to abstract hemoglobin status and other data. Additionally, 81 mothers were interviewed with regard to their nutritional knowledge and feeding practices; these findings were compared with the measured hemoglobin (Hgb) of their children.

RESULTS

A total of 34.9% of children in the study population were found to be anemic (Hgb </= 11. 2). Low childhood Hgb status was significantly correlated with racial identification, child age, maternal perception of feeding difficulty, and the presence of concurrent pediatric medical illness. Report of extensive nutritional discussion with a physician was correlated with normal Hgb levels. No differences in nutritional knowledge or feeding practices were detected between mothers of children with low iron status.

CONCLUSIONS

We conclude that the risk of iron deficiency, even among children receiving WIC services, may be underestimated in certain "nutritionally very high risk" populations. Further study of interventions for IDA in children of young, low-income mothers is recommended.

Iron deficiency and maternal feeding practices among high-risk urban children

This study evaluated the nutritional knowledge and feeding practices (via a verbal questionnaires) of the clients of one semiurban women, infants, and children (WIC) center, which serves exclusively younger women (aged 12-21) and their children, and compared these variables to the hemoglobin levels of their infants and children. No significant benefit from documented WIC education regarding iron was detectable. African American identification was associated with childhood anemia (p = 0.05); the presence of concurrent medical problems approached significance (p = 0.06). Other previously reported risk associations were not found to be significant. Children with low iron ate more meals outside the home per week (2.9 vs. 1.9, p = 0.10). Despite the proven value of the WIC program in reducing childhood iron deficiency, it appears that members of certain very high-risk populations may not experience the full benefit of this nutritional program and may require additional, targeted interventions.
