Bilateral inguinoscrotal swelling: An uncommon presentation of omental cystic lymphangioma.

Abdominal cystic lymphangioma is a rare benign tumour in children. It is often difficult to diagnosis pre-operatively due to a varied spectrum of symptoms. We report a case of a male infant who presented with gross bilateral inguinoscrotal swelling. Provisional diagnosis of congenital communicating hydrocele was made and investigation revealed a large abdominal cyst. Patient underwent explorative laparotomy and the cyst arising from greater omentum, extending into bilateral scrotum, was excised and bilateral herniotomy done. Mass was confirmed to be lymphangioma on biopsy. This case is unique as an abdominal lymphangioma presented solely as inguinoscrotal swelling, with no abdominal symptom. To our knowledge, this is the first case of omental cystic lymphangioma involving both inguinoscrotal regions. Our case suggests that abdominal cystic lymphangioma should be a part of the differential diagnosis in any child with gross inguinoscrotal swelling in whom initial impression is of communicating hydrocele.

Early and late complications of thyroidectomy: A descriptive cohort study in Rawalpindi.

OBJECTIVE: To assess the epidemiology of thyroid disorders and early and late complications following thyroidectomy.. METHODS: The descriptive cohort study was conducted at the Benazir Bhutto Hospital, Rawalpindi, Pakistan, from April 2017 to Janurary 2020, and comprised of patients undergoing total and near-total thyroidectomy. Post-operative complications were noted, and patients were followed up after 6 months to assess long-term complications. Data was analysed using SPSS 22. RESULTS: Of the 75 patients, 70(93.3%) were females and 43(58.1%) were aged <40 years. The most common symptom was neck swelling with hyperthyroidism 20(41.7%) and pressure symptom 20(41.7%). Post-operative complications developed in 26(35.6%) patients, with symptomatic hypocalcaemia being the most common 10(13.7%), followed by hoarseness 6(8.2%). Biopsy results were available for 50(66.6%) patients. Benign pathology was present in 44(88%) patients and 6(12.0%) had malignancy. Follow-up data was available for 62(82.7%) patients among whom symptomatic hypocalcaemia was the leading complication in 33(53.2%), followed by permanent hoarseness in 6(9.7%). CONCLUSIONS: Symptomatic hypocalcaemia and hoarseness were found to be the most common post-operative and long-term complications of thyroidectomy.

The complex role of post-operative magnesium on the long term serum calcium and parathyroid hormone levels in patients undergoing total and near-total thyroidectomy.

Objective: To assess the role of hypomagnesaemia in the development of permanent hypocalcaemia following thyroidectomy. METHODS: The prospective cohort study was conducted from April 3, 2017, to January 2, 2020, at Surgical Unit 1, Benazir Bhutto Hospital, Rawalpindi, Pakistan, and comprised of patients of both genders undergoing total and near total thyroidectomy. Post-operative calcium and magnesium levels were noted, and the patients were followed up after 6 months and fasting serum calcium, magnesium and parathyroid hormone levels were checked. Signs and symptoms of hypocalcaemia were noted. Data was analysed using SPSS 22. RESULTS: Out of the 62 patients followed up, 57 (91.9%) were females and 5 (8.1%) males. The overall mean age was 38.5 ± 12.1 years Post-operative hypomagnesaemia was seen in 6(9.8%) patients and none developed follow-up hypocalcaemia. Post-operative magnesium levels were significantly negatively correlated with follow-up parathyroid hormone level (p=0.006). Fall in magnesium post-operatively and follow-up magnesium were positively correlated with follow-up parathyroid hormone (p<0.05). Permanent hypocalcaemia was seen in 7(11.4%) patients and it was significantly associated with pre-operative and post-operative calcium levels, post-operative symptoms of hypocalcaemia and readmission for hypocalcaemia after discharge (p<0.05). Follow-up hypomagnesaemia was significantly associated with follow-up hypocalcaemia (p=0.024) and follow-up symptoms of hypocalcaemia (p=0.031). Conclusion: Acute development of mild hypomagnesaemia post-operatively may be beneficial in early positive feedback for parathyroid hormone secretion. Hypomagnesemia 6 months after surgery may be involved in PTH organ resistance. The complex role of hypomagnesemia on PTH levels must be further explored.

Frequency of Hypomagnesaemia following Total and Near-total Thyroidectomy and its relationship with Hypocalcaemia.

OBJECTIVE: To determine the frequency of hypomagnesaemia in patients undergoing thyroidectomy and evaluate its relationship with postoperative hypocalcaemia. STUDY DESIGN: Observational, cross-sectional study. PLACE AND DURATION OF STUDY: Surgical Unit 1, Benazir Bhutto Hospital, Rawalpindi, Pakistan from April 2017 to May 2019. METHODOLOGY: Preoperative and 24-hour postoperative samples for serum calcium and magnesium of 75 patients undergoing total and near-total thyroidectomy were taken.  Postoperative signs and symptoms of hypocalcaemia were documented. Data was analysed on SPSS version 22, using independent and paired t-test, Pearson correlation, linear regression, Chi-square test and Fisher's Exact test. RESULTS: Postoperatively 49 (65.3%) patients developed hypocalcaemia and 8 (10.7%) developed hypomagnesaemia. Postoperative hypocalcaemia was significantly associated with hypomagnesaemia (p=0.03) with a significant positive linear correlation. Ten patients (13.3%) developed symptomatic hypocalcaemia; however, it was not associated with postoperative hypomagnesaemia. Postoperative hypocalcaemia and hypomagnesaemia were significantly associated with preoperative calcium level (p = 0.03 and 0.04, respectively). There was significantly lower calcium level in patients with hypomagnesaemia (p = 0.002) and a significant fall in magnesium level in patients developing hypocalcaemia (p = 0.044). CONCLUSION: Postoperatively hypocalcaemia was prevalent following thyroidectomy, while hypomagnesaemia was not common.  Hypomagnesaemia and a fall in magnesium level after surgery was associated with hypocalcaemia; but not with symptomatic hypocalcaemia. Monitoring of magnesium levels in severe or persistent hypocalcaemia is recommended. While this study proves a relationship between calcium and magnesium, its clinical implication must be further studied. Key Words: Calcium, Magnesium, Postoperative, Hypocalcaemia, Hypomagnesaemia, Thyroidectomy.

Early Oral Feeding Compared With Traditional Postoperative Care in Patients Undergoing Emergency Abdominal Surgery for Perforated Duodenal Ulcer.

Introduction Enhanced recovery after surgery (ERAS) protocols have been widely studied in elective abdominal surgeries with promising outcomes. However, the use of these protocols in emergency abdominal surgeries has not been widely investigated. This study aimed to evaluate ERAS application outcomes via early oral feeding compared to regular postoperative care in patients undergoing perforated duodenal ulcer repairs in emergency abdominal surgeries. Materials and methods We conducted a randomized controlled trial at the Surgical Unit 1 Benazir Bhutto Hospital from August 2018 to December 2019. A total of 42 patients presenting to the emergency department with peritonitis secondary to suspected perforated duodenal ulcer were included in the study. Patients were randomly assigned into two groups. Group A patients followed an ERAS protocol for early oral feeding, and Group B received regular postoperative care (i.e., delayed oral feeding). Our primary outcomes were the length of hospital stay, duodenal repair site leak, the severity of pain (via the visual analog scale), and postoperative ileus duration. Results were analyzed via IBM Statistical Product and Service Solutions (SPSS) Statistics for Windows, Version 20.0 (Armonk, NY: IBM Corp.). and chi-square and independent t-tests were applied. Results Patients who received early oral feeding (Group A) showed a shorter length of hospital stay, lower pain scores, and shorter postoperative ileus duration than patients in the traditional postoperative care group. Also, we noted no duodenal repair site leak in the early oral feeding group. The differences between the two groups were statistically significant (P<0.05). Conclusions Based on our results, ERAS protocols that promote early oral feeding can be applied in patients undergoing emergency abdominal surgery for perforated duodenal repair. Early oral feeding in emergency surgery patients can reduce the patient burden on hospitals. In addition, early oral feeding can promote better outcomes and reduced economic burden for patients.

Aphallia: A Very Rare Congenital Anomaly, With Associated Genitourinary And Ano-Rectal Malformation.

Aphallia or penile agenesis is very rare congenital anomaly of unknown cause occurring 1 in 30 million live births. Very little has been written in literature about aphallia. There is absent phallus and urethra may open abnormally in perineum or into rectum posing various surgical, social and psychological implications as the child grows. We are presenting 03 cases of aphallia with associated congenital anomalies such as unilateral renal agenesis, bilateral undescended testes, anorectal malformation and rectovasical fistula.

SiRNA drug delivery by biodegradable polymeric nanoparticles.

RNA interference (RNAi) is an emerging technology in which the introduction of double-stranded RNA (dsRNA) into a diverse range of organisms and cell types causes degradation of the complementary mRNA. It offers a broad spectrum of applications in both biological and medical research. Small interference RNA (siRNA) was recently explored for its therapeutical potential. However, the drug delivery of siRNA oligos is very novel and is in great need of future research. To this end, a biodegradable poly(D,L-lactide-co-glycolide) (PLGA) nanoparticle drug carrier system was prepared to load siRNA oligos with desired physicochemical properties. The nanoparticles were characterized by scanning electron microscopy and laser diffraction particle sizer. The delivery of siRNA into the targeted 293T cells was observed using fluorescent-labeled double-stranded Cy3-oligos. The model siRNA oligos, si-GFP-RNA, were also successfully loaded into PLGA nanoparticles and delivered in 293T cells. The gene silencing effect and the inhibition of GFP expression were investigated using fluorescent microscopy. Both positive and negative controls were used to compare with the new siRNA nanoparticle delivery system. It was found that nanoparticles offered both effective delivery of siRNA and prominent GFP gene silencing effect. Compared to conventional carrier systems, the new biodegradable polymeric nanoparticle system may also offer improved formulation stability, which is practically beneficial and may be used in the future clinical studies of siRNA therapeutics.
