Open rectal cancer resection is associated with a higher rate of sexual dysfunction, but not bladder dysfunction, compared with laparoscopic surgery. Laparoscopic rectal cancer surgery offers a significant advantage with regard to preservation of postoperative sexual function and constitutes a true advance in rectal cancer surgery compared with the open technique. The proposed advantages can be attributed to improvement in visibility by the magnification feature of laparoscopic surgery.

Objective: The objective of this study is to investigate endothelial dysfunction (ED) and arterial stiffness (AS) and determine the association with diastolic dysfunction in children with type 1 diabetes mellitus (DM). Methods: A total of 42 patients without diabetic complications (mean age: 13.21 years) and 40 healthy (mean age: 13.07 years) children were included in this study. AS was assessed with ascending aorta M-mode measurements, diastolic dysfunction with pulsed wave (PW) Doppler and tissue Doppler echocardiography measurements and flow-mediated dilatation (FMD) and carotid intima-media thickness (CIMT) with high-resolution ultrasonography. Results: Results of diabetic group and healthy children were compared. In diabetic group, aortic strain (8.40 ± 2.98, 20.12 ± 5.04; p < 0.001), aortic distensibility (7.36 ± 2.92, 16.59 ± 4.25; p < 0.001) and FMD% (7.70 ± 2.83, 11.33 ± 2.85; p < 0.001) were found decreased, and CIMT (0.52 ± 0.09 mm, 0.47 ± 0.08 mm; p < 0.05) was found increased. Additionally, left ventricular lateral segment and right ventricular free-wall isovolumic relaxation time (IVRT) and myocardial performance index (MPI) were found increased. Correlation analyses demonstrated a negative correlation between FMD and IVRT and MPI. Conclusions: ED and AS were found in type 1 DM patients without diabetic complications. Additionally, correlation was shown between increased AS and ED and right and left ventricular diastolic dysfunctions.

Severe vitamin D deficiency is common in reproductive women and their newborns in LSES cities of Turkey. Covered dressing style, not receiving any vitamin D supplementation and primigravida women are at greatest risk. Vitamin D supplementation campaigns which should cover pregnant women and the newborn to prevent maternal and perinatal vitamin D deficiency should be implemented especially in risk areas.

Hyperinsulinemic hypoglycemia (HH) is the commonest cause of persistent hypoglycemia in the neonatal and infancy periods. Mutations in the ABCC8 and KCNJ11 genes, which encode subunits of the ATP-sensitive potassium channel in the pancreatic beta cell, are identified in approximately 50% of these patients. The first-line drug in the treatment of HH is diazoxide. Octreotide and glucagon can be used in patients who show no response to diazoxide. Nifedipine, a calcium-channel blocker, has been shown to be an effective treatment in a small number of patients with diazoxide-unresponsive HH. We report a HH patient with a homozygous ABCC8 mutation (p.W1339X) who underwent a near-total pancreatectomy at 2 months of age due to a lack of response to diazoxide and octreotide treatment. Severe hypoglycemic attacks continued following surgery, while the patient was being treated with octreotide. These attacks resolved when nifedipine was introduced. Whilst our patient responded well to nifedipine, the dosage could not be increased to 0.75 mg/kg/day due to development of hypotension, a reported side effect of this drug. Currently, our patient, now aged 4 years, is receiving a combination of nifedipine and octreotide treatment. He is under good control and shows no side effects. In conclusion, nifedipine treatment can be started in patients with HH who show a poor response to diazoxide and octreotide treatment.

Objective This study aimed to evaluate presentations of new-onset type 1 diabetes mellitus in a pediatric cohort during the coronavirus disease 2019 pandemic. Materials and Methods: This study was designed as a single-center, descriptive, cross-sectional retrospective study. The patients diagnosed with new-onset type 1 diabetes mellitus between April 1, 2020, and April 1, 2021, were included in the study. The rate of severe acute respiratory syndrome coronavirus 2 polymerase chain reactivity-positivity was investigated. The pandemic period was compared with the same period of the pre-pandemic 2 years in terms of number of new-onset type 1 diabetes mellitus patients, rate of presentation with diabetic ketoacidosis, and degree of diabetic ketoacidosis severity. Results: In total, 56 patients were diagnosed with type 1 diabetes mellitus during the pandemic and 2 (3.57%) of them tested positive for severe acute respiratory syndrome coronavirus 2 polymerase chain reaction. The number of new-onset type 1 diabetes mellitus patients was 39 in 2019 and 39 in 2018. The rate of presentation with diabetic ketoacidosis was similar in the pandemic period compared to the pre-pandemic periods (53.5% in 2020 vs. 56.4% in 2019 and 53.8% in 2018; P = .94). The proportion of severe diabetic ketoacidosis was also similar in all years, respectively (43.3% in 2020 vs. 45.4% in 2019 and 47.6% in 2018; P = .95). Conclusion: We reported only 2 cases that tested positive for severe acute respiratory syndrome coronavirus 2among the new-onset type 1 diabetes mellitus patients during the pandemic. Although we found an increase in the number of new-onset type 1 diabetes mellitus cases by comparing with prepandemic period, rates of diabetic ketoacidosis and severe diabetic ketoacidosis were similar. There was no finding to suggest that severe acute respiratory syndrome coronavirus 2taking a part in type 1 diabetes mellitus pathogenesis. Since the development of type 1 diabetes mellitus is a long process, prospective studies are needed to investigate the long-term effects of severe acute respiratory syndrome coronavirus 2.

Ectopic intrathyroidal thymus tissue that may be present as a thyroid nodule is rarely reported. We present a case of a 4-year-old boy with a solitary thyroid nodule. Real-time thyroid ultrasound showed a calcified nodule in the right lobe. Complete blood count, serum calcitonin, and thyroglobulin concentration were normal and antithyroid antibodies were negative. Fine-needle aspiration (FNA) biopsy was revealed as inadequate for cytological examination. During his follow-up, nodular enlargement was found, and the patient was subjected to surgical total excision of the right lobe of the thyroid gland. Pathological examination showed an ectopic intrathyroidal thymus tissue. In childhood, ectopic intrathyroidal thymus tissue can present as an enlarging microcalcified thyroid nodule that may mimic thyroid cancer and may grow during follow-up.
