Papillary and follicular thyroid carcinomas arising from the follicular epithelial cells and forming differentiated thyroid cancer (DTC) consist of >95% of thyroid cancers. Lymph node metastasis to the neck is common in DTC, especially in papillary thyroid cancer. The removal of only the metastatic lymph nodes (berry picking) does not help to achieve a potential positive contribution to the survival and recurrence of lymph node dissection in the DTC. Thus, systematic dissection of the cervical lymph nodes is needed. Today, according to the widely accepted and commonly used definitions and lymph node staging, the deep lymph nodes of the lateral side of the neck are divided into five regions. Based on the fact that some groups have biologically independent regions, Groups I, II, and V are divided into the A and B subgroups. The central region lymph nodes contain VI and VII region lymph nodes, which consist of the prelaryngeal, pretracheal, and right and left paratracheal lymph node groups.
Radical neck dissection (RND) is accepted as the standard basic procedure in defining neck dissections. In this method, in addition to all the regions of the Groups I–V lymph nodes at one side, the ipsilateral spinal accessory nerve, internal jugular vein, and sternocleidomastoid muscle are removed. Sparing of one or more of the routinely removed non-lymphatic structures in the RND is called modified RND (MRND), whereas the preservation of one or more of the routinely removed lymph node groups in the RND is termed as selective neck dissection (SND). In difference, the procedure with an addition of a lymph node and/or non-lymphatic structures to routinely removed neck structures in RND is called extended RND. Generally, involving one or more regions of SND are applied for DTC.
The removal of the paratracheal, prelaryngeal, and pretracheal lymph node groups at one side is termed as ipsilateral central dissection, whereas the removal of the bilateral paratracheal lymph node groups, in other words, the excision of four lymph node groups in the central region (Groups VI and VII), is defined as bilateral central dissection. In conclusion, bilateral central neck dissection (CND) is the SND in which the regions of VI and VII are removed.
In the DTC, CND is prophylactically and therapeutically applied, whereas lateral neck dissection is performed only therapeutically in the presence of clinical metastasis (N1b) in the lateral neck region. Debates on the extent of SNDs to be made in the central and lateral neck regions are still ongoing. Central dissection should be made at least unilaterally. In the lateral side of the neck, SNDs can be applied in different combinations in which at least one region from Groups I to V is removed. The main variables that determine the extent of SND in the central and lateral regions in DTC are the complication rates, the effect of the procedure, and its effect on prognosis and recurrence.

PMID: 32595392  PMCID: PMC7315095  doi: 10.14744/SEMB.2017.92905  Pages 164 - 168
Objectives: Our aim was to study whether laparoscopic appendectomy radix ligation techniques were eutrophic in the development of intra-abdominal abscess.
Methods: Between September 2009 and April 2017, all emergency cases admitted to our surgery polyclinic were reviewed, and the results of the patients who underwent laparoscopic appendectomy were collected. Appendectomy radix ligation techniques were reviewed from surgical notes on discharge reports. Postoperative controls were also reviewed, and any cases with abscess formation were reported.
Results: A total of 350 patients were included in the study. Of these cases, 207 were males, and 143 were females. The mean age of the patients was 26.89±4.9 years. One hundred eighty-nine cases were found to have two endoloops placed on top of each other, whereas 161 cases had a 2 mm distance left in between the two endoloops and tied. None of the 189 cases who had endoloops placed on top of each other developed abscess formation. However, of the 161 cases who had endoloops with a 2 mm distance in between, 8 reported with abscess formation in the inner abdomen. Of these eight cases, seven had percutaneous abscess drainage by an interventional radiologist, whereas one was treated with relaparoscopy.
Conclusion: In the present study, patients who had endoloops placed on top of each other developed no abscess formation, whereas in the literature’s gold standard procedure, those with a 2 mm distance left between two endoloops developed an inner abdominal abscess formation in 8 (4.9%) of the patients. We believe that this 2 mm dead space distance left between the two endoloops contributes to the formation of the abscess.

Objectives: Laparoscopic gastrostomy is a widely used procedure in children with failure to thrive, feeding disorders, or neurologic impairment. Various methods of laparoscopic gastrostomy and fixing stomach to abdominal wall have been described. Trocar site primary gastrostomy under laparoscopic control is a simple and easy technique that does not require special instruments and a kit. The aim of this study was to present 10 years of experience in laparoscopic gastrostomy.
Methods: The charts of 128 children who underwent laparoscopic gastrostomy between 2006 and 2016 were retrospectively reviewed. The data, including demographics, operative procedures, and complications, were recorded. All children underwent preoperative contrast imaging and 24-hour Ph monitorization. In all patients, the trocar site primary gastrostomy was done. A gastrostomy tube or a button was inserted into the stomach in the center of a purse–string suture loop, and the stomach was fixed to the anterior rectus sheath extracorporeally.
Results: There were 49 girls (38.3%) and 79 boys (61.7%). The mean age was 50 months at surgery (1 day–18 years), and the average body weight was 13 kg (2300 gr–65 kg). Both laparoscopic Nissen fundoplication and gastrostomy were done in 116 (90.6%) patients, and 12 (9.4%) patients had only laparoscopic gastrostomy. Infection at the site of gastrostomy, which was treated by antibiotics, was the most common complication, observed in 14 (11%) patients. Peritoneal leakage within 30 days was seen in 9 (7%) patients. Severe dislodgement of gastrostomy resulting in operative intervention occurred in 5 (3.9%) patients. Granuloma developed in 4 (3.1%) patients and was treated with silver nitrate.
Conclusion: The trocar site primary laparoscopic gastrostomy is a safe and easy technique with complication rates comparable to other gastrostomy methods.

PMID: 32595394  PMCID: PMC7315085  doi: 10.14744/SEMB.2018.07078  Pages 173 - 178
Objective: The aim of the present study was to present the results of patients with unstable distal radius fracture treated with closed reduction and percutaneous fixation followed by application of the Pennig dynamic wrist fixator to allow early wrist motion.
Methods: Twenty-five patients diagnosed with distal radius fracture and treated with closed reduction and percutaneous fixation followed by application of a dynamic wrist fixator were included in the study. There were 15 (60%) male and 10 (40%) female patients. The mean age of the patients was 47.32 (20–76) years. The mean period between initial trauma and operation was 8.52 (1–23) days. All patients were allowed active shoulder, elbow, and finger exercises immediately after surgery.
Results: Radiological evaluation was performed according to the criteria described by Sarmiento and modified by Lidström. Results were excellent in 12 (46.15%), good in 11 (42.30%), and fair in 3 (11.55%) patients. No patient had poor result. Functional scores were assessed according to the Gartland–Werley classification and modified by Sarmiento. Results were excellent in 14 (56%), good in 8 (32%), and moderate in 3 (12%) patients.
Conclusion: Use of the Pennig dynamic wrist fixator in the treatment of unstable distal radius fractures has advantages, such as ease of use, minimal surgical trauma, allowing early rehabilitation, and early return to daily activities as well as increased anatomical and functional results.

Objectives: Chronic otitis media (COM) reveals a spectrum of otoscopic findings, and both ears may be affected to a different degree. The analysis of contralateral ear in patients with COM is important to detect the early signs of the disease. This may enable the follow-up and treatment of abnormalities in contralateral ear without delay. Therefore, in this study, we aimed to investigate the otoscopic and audiologic findings of contralateral ears of patients with COM.
Methods: The institutional data of patients who underwent surgical treatment between 2014 and 2017 due to COM were reviewed. Suppurative ears with cholesteatoma, polyps, and otorrhea refractory to medical treatment and ears with dry middle ear mucosa, with otorrhea responsive to medical treatment, and without cholesteatoma were divided into two groups (Group 1 and Group 2, respectively). All patients were examined with regard to the presence of perforation, retraction, myringosclerosis, atrophy, and audiological results before the groups were compared.
Results: Approximately 50% of contralateral ears of patients with COM showed abnormalities at an otoscopic examination in both groups. Tympanic membrane retraction in Group 1 was greater than in Group 2, and the difference was statistically significant (p<0.05). Both the mean air and bone conduction thresholds of the contralateral ears in Group 1 were also found to be elevated when compared with Group 2, and the differences were statistically significant (p<0.05).
Conclusion: COM may be seen bilaterally due to the same predisposing factors affecting the ears. Therefore, detection, follow-up, and early treatment of abnormalities of contralateral ear associated with otitis media have clinical importance in the prevention or delaying progression of these abnormalities to COM.

PMID: 32595396  PMCID: PMC7315084  doi: 10.14744/SEMB.2018.59219  Pages 184 - 189
Objectives: Residual renal function (RRF) at the initiation of peritoneal dialysis (PD) therapy can be a predictor of survival in stable PD patients. The aim of the present study was to investigate PD patients regarding the effect of baseline RRF on patient and technique survival.
Methods: Urine output at the beginning of PD therapy was evaluated retrospectively in 202 PD patients. Patients were divided into two groups: patients with anuria (urine output ≤100 ml/day) and patients without anuria (urine output >100 ml/day).
Results: The number of patients with anuria was 58 in which 38 patients were females. The mean age of the patients was 42.8±14.9 years. The mean follow-up period was 44.2±35 months. Twelve percent of patients with anuria had history of hemodialysis (HD).
One hundred forty-four had no anuria (68 females, mean age 43.7±14.5 years, mean follow-up period 39.6 ± 26.1 months, mean urine volume 592±442 ml). Twenty-three patients had received HD therapy before. Sixty-five had anuria in the following 22.5±19.6 months.
At the beginning of therapy, systolic and diastolic blood pressures were lower in patients with oliguria than in patients without oliguria (p<0.001), but C-reactive protein (p=0.004) and ferritin (p<0.001) levels were higher. There was no difference between two groups regarding the other parameters (age, follow-up periods, presence of diabetes, ultrafiltration volumes, albumin, hemoglobin, calcium phosphorus product, parathormone, and Kt/V levels) (p>0.05).
The peritonitis rate was one episode per 28.2 versus 30 patient-months for the anuric and non-anuric groups, respectively (p>0.05).
For Kaplan–Meier survival analysis, the mean technique survival rates at 1 and 3 years were 97% and 86.6% in patients without anuria and 94% and 85.3% in patients with anuria, respectively. The 5-year technique survival rates according to residual volume states were not statistically significant with log-rank test (p>0.05).
The 1-, 3-, and 5-year survival rates were 96.9%, 89.6%, and 86.5% in patients without anuria, respectively, whereas they were 87.3%, 77.3%, and 53.7% in patients with anuria, respectively. The 5-year survival rates according to residual volume states were statistically significant (p<0.05).
Conclusion: RRF at the beginning of PD has an important and positive impact on patient survival in PD patients. Peritonitis rates and technique survival were not different for patients with anuria and without anuria.

PMID: 32595397  PMCID: PMC7315093  doi: 10.14744/SEMB.2018.75537  Pages 190 - 195
Objectives: Contrast-induced nephropathy (CIN) accounts for 10% of all causes of hospital-acquired renal failure. The pathophysiological cellular mechanism of the CIN development remains unclear and seems to be multifactorial. Herein, we aimed to determine the role of red cell distribution width (RDW) in the development of CIN after elective percutaneous intervention in patients with stable coronary artery disease, which in our opinion has not been researched enough.
Methods: Between October 2009 and October 2011, a total of 211 patients with stable coronary artery disease who had undergone a coronary intervention procedure were evaluated prospectively. The patients were classified according to the development of CIN, and both groups were compared statistically according to clinical, laboratory, and demographic features, including the serum RDW level.
Results: In 18.8% of the patients, CIN was observed. The mean age was 64±10.5, and 59% of the study group was male. An advanced age, male gender, hypertension, the serum total protein level, high density lipoprotein, and albumin levels were correlated with the development of CIN. The mean RDW level was 13.7±1.4%, and the mean creatinine level was 1.0±0.2 mg/dL. There was not any correlation between RDW and the presence of CIN (CIN[−]=13.8±1.5, CIN[+]=13.6±1.0, p>0.05), and also a multivariate regression analysis proved this non-correlation (OR: 0.92, 95% confidence interval [CI]=0.62–1.34; p: 0.67 ). There was only a correlation between hypertension and male gender with CIN that was proved with a multivariate regression analysis (OR=5.74, 95% CI: 1.96–16.79, p<0.01 vs OR=5.34, 95% CI=1.22–23.3, p: 0.02, respectively).
Conclusion: Our outcomes indicate that the RDW has a limited use as a CIN predictor in patients with stable coronary artery disease.

PMID: 32595398  PMCID: PMC7315097  doi: 10.14744/SEMB.2018.63325  Pages 196 - 200
Objectives: Clinical evidence supports the association of toll-like receptor (TLR) with abnormal cell proliferation and cancer. In this study, we investigated the expression of TLRs 2, 4, 5, and 6 in healthy endometrium and endometrium cancer to study the relationship of these receptors’ expression with carcinogenesis.
Methods: Patients who had undergone a hysterectomy owing to endometrium cancer (group 1, 66 patients), endometrial hyperplasia (group 2, 14 patients), and other reasons besides endometrium cancer (group 3, 20 patients as controls) were included. The cases in the first group were classified by histological type of the cancer, stage, grade, and size of the tumor. In all the cases, expressions of TLRs 2, 4, 5, and 6 were assessed, and the relationship of these receptors with clinicopathologic signs was analyzed. For immunohistochemical staining, nuclear and cytoplasmic stainings were considered positive. A Chi-squared test was used to assess the correlation of the groups. A p<0.05 was considered significant.
Results: The mean ages of patients in groups 1, 2, and 3 were 59.8 (range 33–83), 48.3 (range 40–59), and 53.4 (range 38–84) years, respectively. All types of TLRs were highly expressed in both types of endometrium cancer (groups 1 and 2). TLR expression was observed with a ratio of 87.9% in group 1, 100% in group 2, and 35% in group 3. There was a statistically significant association of TLR 2 among the three groups (p=0.000). TLR 6 expression in both group 1 and group 2 was significantly higher than that in the control group (p=0.000, p=0.000, respectively). In addition, TLR 6 was higher in cases with late-stage cancer (p=0.033). Regarding tumor grade and the size of the tumor, no association was found between TLR 2 and TLR 6.
Conclusion: TLR 2 and TLR 6 were significantly more expressed in cases with endometrium cancer and endometrial hyperplasia. In addition, the presence of TLR 6 may indicate the presence of late-stage endometrial cancer.

Objectives: There is good evidence that shows that modification of modifiable risk factor will reduce the risk of stroke. Hyperlipidemia is one of these risk factors. Studies have shown that nontraditional serum lipid variables may be better predictors of vascular risk rather than others.
The objective of the present study was to assess the relationships of traditional and nontraditional serum lipid measurements between young and elder patients with stroke and healthy young adults.
Methods: One hundred twelve young patients with ischemic stroke, 113 healthy adults, and 110 patients with ischemic stroke aged >45 years were included in the study. Laboratory tests for total cholesterol (TC), its fractions, and triglycerides (TGs) were performed using standard techniques, and we computed four nontraditional lipid variables.
Statistical analyses were performed using chi-square test, Student's t-test, and SPSS version 16.0 software. A p value of <0.05 was considered statistically significant.
Results: The mean age of 112 young patients with stroke was 38.46±5.96 years. There were 63 male and 49 female patients. Measurements of lipid parameters were as follows: low-density lipoprotein (LDL) 121.42±36.56 mg/dl, high-density lipoprotein (HDL) 38.84±12.47 mg/dl, TG 186.10±176.14 mg/dl, TC 194.76±45.35 mg/dl, LDL/HDL 3.39±1.46, TG/HDL 5.44±6.36, and TC/HDL 5.40±6.36. All lipid measurements were significantly higher in young patients with stroke than in healthy adults.
The mean age of 110 patients with stroke aged >45 years was 69.53±12.34 years. There were 63 male and 47 female patients. Measurements of lipid parameters were as follows: LDL 125.18±35.97 mg/dl, HDL 41.47±14.16 mg/dl, TG 117.53±59.03 mg/dl, TC 190.16±42.96 mg/dl, LDL/HDL 3.32±1.55, TG/HDL 3.46±3.43, and TC/HDL 5.01±2.08. TG level and TG/HDL ratio were significantly higher in young patients with stroke than in older cases.
Conclusion: All lipid measurements were significantly higher in young patients with ischemic stroke than in young healthy adults. TG level and TG/HDL ratio were significantly higher in male than in female patients. In addition, TG level and TG/HDL ratio were significantly higher in young patients with stroke than in older cases. As the TG/HDL ratio has proven to be a highly significant independent prognostic predictor of stroke, it should be calculated in young patients with ischemic stroke.

PMID: 32595400  PMCID: PMC7315096  doi: 10.14744/SEMB.2018.07769  Pages 206 - 211
Objectives: The aim of the present study was to investigate the diagnostic effectiveness of uterine and cervical vascularity alone or in combination with human papillomavirus (HPV) DNA testing and with cytology.
Methods: Data were prospectively collected from 129 patients in an outpatient clinic of a secondary setting. Routine liquid-based cervical cytology and HPV-DNA testing were obtained. An abnormal result of any of these high-risk types was viewed as positive. Pulsatility (PI) and resistance (RI) indices of uterine (UA) and cervical (CA) arteries were assessed by Doppler sonography. Pathological diagnosis was considered as the gold standard for assessment. Diagnostic efficiency of alone and joint screening of the three indices for discriminating cervical intraepithelial neoplasia (CIN-I) or above from below was assessed.
Results: UA-RI and CA-RI were significantly lower in the HPV (+) group than in the controls (p=0.02 and p=0.03, respectively). In subsequent sub-analysis among patients with positive HPV-DNA, UA-PI was significantly higher in the HPV-16 (+) group than in the HPV-18 (+) group (p=0.04). High-risk HPV (Hr-HPV) testing had the highest sensitivity compared with Doppler and cytology (76.5%, 64.7%, and 58.5%, respectively). Combining CA-RI with cytology or Hr-HPV significantly reduced the sensitivity (23.5% and 29.4, respectively) but improved the specificity from 54.4% to 69.8% and 40.9% to 70.7%, respectively. Combining UA-PI with Hr-HPV slightly increased the positive predictivity when compared with testing Hr-HPV alone (36.1% vs. 33.3%).
Conclusion: The potential of the Doppler indices of UA and CA was doubtful in discriminating CIN-I or above lesions in the early period. In addition, RI of UA and CA differed with regard to the presence of HPV infection, whereas CA-RI differed in high-risk HPV cases.

PMID: 32595401  PMCID: PMC7315086  doi: 10.14744/SEMB.2018.66933  Pages 212 - 219
Objectives: To examine the effect of celecoxib on wound healing and development of seroma after mastectomy.
Seroma is an accumulation of serous fluid in dead space emerging after breast cancer surgery. The pathophysiology of seroma has not been clearly elucidated. Development of seroma leads to prolongation of hospital stay, increase in costs, ischemia of the flaps, infections due to fluid accumulation, and delayed adjuvant treatment.
Seroma is still a current problem, and the most common treatment method for this problem is drainage and repeated aspirations for 5–7 days after surgery.
Methods: The effect of celecoxib whose anti-inflammatory, antiangiogenic, and antioxidant effectiveness has been demonstrated in a mastectomy model applied on female Wistar rats has been investigated in the present study. A total of 20 rats including 10 rats in the control and 10 in the celecoxib group were studied.
Intraperitoneal 0.25 cc/250 g (20 mg/kg/day) celecoxib was administered to the celecoxib group for 5 days after mastectomy, and the same volume of physiological saline solution was given to the control group for 5 days. Rats were followed up for 10 days after surgery. During this process, vitality of the rats, movements of the extremities, wound healing conditions, wound infections, flap necrosis, and occurrence of seroma were recorded. At the end of this period, seromas were aspirated, tissue samples were retrieved, and the rats were sacrificed. Fibrin, hemorrhage, edema, vascularization, congestion, polymorphonuclear leukocytes, and increase in fibrotic tissue fibroblasts, lymphocytes, and macrophages were evaluated in tissue samples.
In seroma fluids, interleukin-1 beta (IL-1β), an acute phase reactant, and vascular endothelial growth factor, a vital parameter of vascular proliferation and angiogenesis, were examined.
Results: At the end of the experiments, the seroma volume decreased significantly in the celecoxib group (p=0.804; 0.001), the IL-1β level decreased significantly as detected in the biochemical examination (p=0.014), and in the histopathological examination, an increase in congestion in the celecoxib group was determined.
Conclusion: In conclusion, celecoxib markedly decreased interleukin and the volume of seroma after mastectomy; suppressed the level of an acute phase reactant, IL-1β; and demonstrated this effect through its anti-inflammatory activity. We believe that the effects of celecoxib should be investigated using different dose applications and larger number of subjects.

Acute hemorrhagic edema of infancy is a leukocytoclastic small vessel vasculitis of young children that is limited to the skin, generally has a benign course without systemic involvement, and does not require treatment. It is characterized by fever, edema of the lower extremities, and wide purpuric rash of the skin. It typically affects infants aged 6–24 months with a history of recent respiratory system illness. An 11-month-old and a 57-month-old cases with acute hemorrhagic edema of infancy who concurrently have a lower respiratory system infection are presented in this case report.

Desmoplastic infantile astrocytomas (DIAs), are rare supratentorial tumors, usually observed in the first 24 months of life. Despite their aggressive appearance, they tend to follow a favorable clinical course. Total or near total resection of tumor is usually the treatment option. Desmoplastic Infantile Ganglioglioma (DIG) and DIA are WHO grade I tumors that have similar clinical and morphological findings. The only criterion in differential diagnosis is the neural component of DIG. These tumors both have dense fibroblastic stroma and positive staining with glial fibrillar acidic protein (GFAP) and CD34.
A rare case of desmoplastic infantile astrocytoma presenting with right side partial seizures presented in a 1-year-old child.
A rare case of desmoplastic infantile astrocytoma presenting with focal onset generalized seizures presented in a 1-year-old child.
Despite their radiological and histological properties, these tumors have a benign course. After 3-year follow-up for the first case and 1-year follow-up for the second case, there was no recurrence.

PMID: 32595404  PMCID: PMC7315094  doi: 10.5350/SEMB.20170508042536  Pages 229 - 231
Although extranasopharyngeal angiofibroma (ENA) is a rare condition, its diagnosis should be considered during differential diagnosis of nasal masses. We report a rare case of ENA originating from the left lateral side of nasal tip.
A 43-year-old man with an ENA mass located on the left lateral side of the nasal tip presented to our hospital. The nasal mass caused nasal obstruction and swelling at the nasal tip and was surgically removed. Histopathological examination revealed ENA. The patient is being followed up and remains free of disease.
ENAs are rare and differ from nasopharyngeal angiofibromas regarding clinical and radiological features. Although it is rare, the diagnosis should be considered during differential diagnosis of a patient with one sided nasal mass and/or with refractory epistaxis, regardless of the patient’s age or sex.
