Are trauma victims with obesity lucky in penetrating trauma injuries?

BACKGROUND

We aimed to reveal the protective effect of body mass index (BMI) and subcutaneous adipose tissue thickness (SATT), together with scores covering the abdomen, in patients with penetrating abdominal trauma.

METHODS

The data of 234 abdominal penetrating trauma patients over the age of 16 who applied to the emergency general sur-gery unit of Istanbul Medipol Hospital between 2017 and 2021 were analyzed retrospectively. Sex, age, types of penetrating injuries, BMI, need for blood transfusion and intensive care unit (ICU), mortality, Injury Severity Score (ISS), Penetrating Abdominal Trauma Index (PATI), and Flint Colon Injury Score (FCIS) were recorded.

RESULTS

The patients were divided into two groups: Gunshot Wound (GW) and Stab Wound (SW).While there was no significant difference in all parameters examined in all patients and GW patients in terms of BMI, a statistically significant difference was found in terms of blood transfusion need in SW patients (p=0.035). As a result of the Receiver Operating Characteristic curve analysis for the SATT variable, the cutoff value between mortality (p=0.866) and SATT (mm) values in all patients was 11 mm for all patients and 12 mm for GW patients. A significant difference was found in all patients and separately in GW and SW groups in terms of ICU and blood transfusion need, length of stay, ISS, PATI, and FCIS scores in non-operated patients (p<0.05). When all patients were examined, a statistically significant difference was found in terms of mortality (p=0.002).

CONCLUSION

It is the first study to evaluate penetrating abdominal injuries with both BMI and SATT comprehensively and with all abdominal scores. A cutoff value to be determined for SATT with larger and multicenter studies can take its place as a parameter in the penetrating trauma algorithm.

Effect of glutamine use on the formation of intestinal neomucosa on peritoneal surface in rats

BACKGROUND

Short bowel syndrome (SBS) is a clinical condition with high mortality and morbidity, which leads to the lack of absorption of fluids or nutrients necessary for the body due to the decrease in the length of the small bowel (SB). Glutamine is an amino acid essential for the nutrition and proliferation of intestinal mucosa cells. The main aim of the present study was to investigate the effect of glutamine on intestinal neomucosa formation in rats which developed SBS.

METHODS

Sixteen Wistar Hannover rats were randomly divided into two groups of eight rats. Saline was applied to the rats in Group 1 (control) following the enteroperitoneal anastomosis between mucosal surface of the ileum and the parietal peritoneum surface (adherent to abdominal wall) while glutamine was applied to the rats in Group 2 following the same anastomosis. Fourteen days later, the rats were euthanatized and blood samples were taken. Simultaneously, en bloc resection of the anastomosis part was performed and histopathological examination was carried out to observe neomucosa formation. The effects of glutamine on anastomosis were determined by microscopic and biochemical evaluations.

RESULTS

Biochemical analyses were performed by measuring serum oxidant (malondialdehyde [MDA] and 8-hydroxy-2'-deoxyguanosine [8-OHdG]) and antioxidant (superoxide dismutase [SOD] and glutathione peroxidase [GPx]) parameters. Based on the biochemical evaluation results of the antioxidant values of the control and glutamine groups, it was found that while the serum antioxidant level (SOD and GPx activity) was significantly higher (p<0.05) in the glutamine-administered rats compared to the control group, the oxidative damage (MDA and 8-OHdG) was lower (p<0.05). In terms of the histological evaluations made for the neomucosa formation, the number of neomucosa formation was higher in the glutamine group, but the difference was not significant (p=0.315).

CONCLUSION

The use of glutamine in patients with SBS may increase surface absorption by increasing neomucosa formation. However, additional studies of large statistical power are needed.

Long-acting new generation antipsychotics in the maintenance treatment of bipolar disorders

Introduction

Maintaining remission, preventing from future episodes, better treatment adherence and improving the quality of life are main aims of long-term treatment in bipolar disorders (BD). In recent years, new generation long-acting injectable (LAI) antipsychotics have been frequently used in maintenance treatment for bipolar disorders.

Objectives

We aimed to review socio-demographic and clinical characteristics of bipolar patients taking LAI treatment for maintenance treatment.

Methods

Clinical records of 44 bipolar patients who are on LAI treatment and followed in Mazhar Osman Mood Clinic (MOMC) of Selcuk University Medical Faculty were evaluated.

Results

Nearly half of the patients were male (n:24, 54%). 43,2% of the patients were married. The mean age was 36.6±11.9 years and the mean duration of education was 11.5±3.9 years. All of the patients were diagnosed with bipolar 1 disorder. Most of the patients (65.9%) was on aripiprazole LAI while remaining was receiving paliperidone LAI for maintenance treatment. Ten of the patients discontinued the treatment due to the side effects and extrapyramidal side effects was the most common side effect. Relapse was observed in 25% of the patients and there was no difference between aripiprazole and paliperidone in terms of relapse rate.

Conclusions

LAI new generation antipsychotics are taking place in long-term treatment of bipolar disorder via improving treatment adherence. Side effect profile of aripiprazole and paliperidone are different. However, we could not find any difference between two drugs in terms of side effects and relapse rates. Small sample size and shorter duration of follow-up should be considered as limitations.

Emotional Dysregulation and Altered Reward Processing in Self-Harm

Introduction

Self-Harm (SH) is any act of self-injury carried out by somebody irrespective of motivation. SH most commonly functions to relieve negative affect (NA). Tentative evidence suggests reward processing is altered in SH. NA may trigger reward hypersensitivity and therefore SH. Whether NA influences reward processing in SH remains unclear.

Objectives

To investigate whether self-harmers differ in motivation to obtain SH stimuli than healthy controls (HCs) following NA induction.

Hypothesis

After NA induction, SH participants will have a significantly shorter reaction latency (RL) and greater reaction accuracy (RA) than HCs in the SH condition of the Incentive Delay (ID) task.

Methods

16-25-year-old SH (n=35) and HC (n=20) participants were recruited online and underwent the Trier Social Stress Test, to induce NA, followed by the ID task, where participants were cued to respond to a target as quickly as possible. On responding, an image of either a SH act (SH Condition), people socializing (Social Condition) or money (Monetary Condition) appeared. Each condition included control trials showing a neutral image. RA was the percentage of trials responded to within the target’s presentation time. RL was the time (seconds) between target appearance and participants’ response.

Results

There was no significant main effect of group, condition or group x condition interaction for RL. There was a significant main effect of condition (p < 0.05) but not of group nor a group x condition interaction for RA.

Conclusions

Reward processing did not differ in the SH group compared to HCs post-NA induction. Future studies could investigate reward processing in longitudinal and larger SH samples.

Disclosure

No significant relationships.

Cordycepin prevents the esophageal stricture formation in the alkali-burn rat model by exerting anti-inflammatory and antifibrotic effects

Purpose

To investigate the efficacy of cordycepin, an adenosine analogue, on prevention of esophageal damage and stricture formation due to esophageal caustic burns in rat model comparing with prednisolone.

Methods

Caustic esophageal burn was introduced by 37.5% of NaOH to distal esophagus. Thirty-two Wistar albino rats were divided in four groups: sham rats undergone laparotomy, treated with 0.9% NaCl; control rats injured with NaOH without cordycepin treatment; cordycepin group injured with NaOH, treated with 20 mg/kg cordycepin; prednisolone group injured with NaOH, treated with 1 mg/kg prednisolone for 28 days. Efficacy was assessed by histopathological and immunohistochemical analysis of esophageal tissues.

Results

Cordycepin treatment significantly decreased inflammation, granulation tissue and fibrous tissue formation and prevented formation of esophageal strictures shown by histopathological damage score and stenosis indexes compared to control group (p < 0.01). These effects are relatively more substantial than prednisolone, probably based on attenuation of elevation of proinflammatory cytokines hypoxia-inducible factor 1-alpha (HIF-1?), tumor necrosis factor alpha (TNF-?), proliferative and fibrotic factor fibroblast growth factor 2 (FGF2) and angiogenic factor vascular endothelial growth factor A (VEGFA) (p < 0.05).

Conclusions

The findings suggest that cordycepin has a complex multifactorial healing process in alkali-burned tissue, more successful than prednisolone in preventing the formation of esophageal strictures and may be used as a therapeutic agent in the acute phase of esophageal alkali-burn.

COVID-19 and acute biliary pancreatitis: comparative analysis between the normal period and COVID-19 pandemic

BACKGROUND

The development of acute pancreatitis is multifactorial requiring predisposition and relevant injury.Viral acute pancreatitis has been described in other viral infections.However, pancreatic involvement in SARS-CoV-2 infection is still poorly defined.The present comparative study reports the patients with acute pancreatitis during the COVID-19 pandemic and last year covering the same period to appraise the link between COVID-19 and acute biliary pancreatitis.

METHODS

The retrospective observational study was conducted in acute biliary pancreatitis patients from 13.03.19to13.09.19 and from 13.03.20to13.09.20 respectively.

RESULTS

The study included 181patients(105patients in 2019;76 patients in 2020(during COVID-19 pandemic)).The patients were named as Group A(Normal period)and GroupB(Pandemic period),respectively.The groups were found to be comparable as there was no significant difference between the mean age, sex, comorbidities, cholecystectomized, and recurrency. There is no significant difference in the laboratory and radiological findings of GroupA and GroupB. However, there is a significant difference between the COVID-19 positive and negative patients in GroupB in terms of Glucose levels(p=0,025)and the presence of edema or necrosis in radiological images(p=0,046).There is a significant difference between the patients' number with abdominal pain of acute biliary pancreatitis in 2019and2020.(p=0)The length of stay was statistically significant in COVID-19 positive patients.(p= 0,013) CONCLUSIONS: Clinicians involved in the management of acute pancreatitis should be aware of its existence in the context of COVID-19.Understanding of the disease process and clinical manifestations of COVID-19 is still developing.Awareness of these issues and addressing them adequately will be crucial for the management.

A comparison of the quantitative evaluation of in situ parathyroid gland perfusion by indocyanine green fluorescence angiography and by visual examination in thyroid surgery

Objective The most vital complications of thyroidectomy are recurrent nerve damage and hypocalcaemia. We aimed to compare the tissue perfusion scores (PS) of IG fluorescence angiography (IGFA) and visual examination by the surgeon after total thyroidectomy. Subjects and methods Forty-three patients were accepted into the study. Localisation of the parathyroid gland (PG) was determined by the naked eye and scored in terms of tissue perfusion. The averages of fluorescent light intensities for each IGFA were calculated, the perfusions were scored and compared with the PS given by the surgeon. Biochemical parameters were noted. Results 37.2% of patients had autotransplanted PGs, according to their visual scores. The means of IGFA-PS for PGs scored as 0, 1 or 2 on visual inspection were 48.58 ± 4.49 [30-70], 89.65 ± 8.93 [36-144] and 158.76 ± 8.93 [70-253], respectively, which correlated with the visual PSs in a statistically significant manner (P < 0.0001). The predictive cut-off value for IGFA-PS was determined to be 70, given a visual PS of 0 (95% CI [0.72-0.85]), and this was interpreted to be a candidate cut-off point for the autotransplantation of PGs. Conclusion IGFA scoring may be considered as an operative predictor, providing objective criteria to evaluate the tissue and blood perfusion of PGs after thyroidectomy. IGFA scoring may be considered to have value in minimising postoperative permanent hypoparathyroidism in patients.

Intravenous metoclopramide versus dexketoprofen trometamol versus metoclopramide+ dexketoprofen trometamol in acute migraine attack in the emergency department: A randomized double-blind controlled trial

STUDY OBJECTIVE

The objective of this study was to determine the analgesic efficacy and safety of intravenous, single-dose metoclopramide versus dexketoprofen trometamol versus metoclopramide+ dexketoprofen trometamol in patients presenting with acute migraine attack to the emergency department (ED).

METHODS

This single-center, randomized, double-blind study was conducted in a tertiary care ED. Eligible patients met the migraine criteria of the International Headache Society were randomized to receive 10 mg intravenous metoclopramide, 50 mg intravenous dexketoprofen trometamol, or 50 mg dexketoprofen trometamol +10 mg metoclopramide. Visual analogue scale (VAS) was used for pain measurement at baseline, after 15 and 30 min. The primary outcome measure was the changes in the VAS scores at the 15th and 30th minutes of treatment. The secondary outcome measures were the presence of adverse effects and the requirement of rescue medicine.

RESULTS

Patients (n = 150) were randomized into 3 groups with similar VAS scores at baseline. While there was no significant difference between metoclopramide and dexketoprofen trometamol in reducing pain at the 15th and 30th minute (p = 0.618 and p = 0.862, respectively) and between metoclopramide and metoclopramide + dexketoprofen trometamol at the 15th minute (p = 0.074), metoclopramide + dexketoprofen trometamol was superior to both metoclopramide [mean difference: -13.2 mm (95% CI -23.1 to -3.3)] and dexketoprofen trometamol [mean difference: -11.02 mm (95% CI -20.9 to -1.1)] at the 30th min (p = 0.006 and p = 0.025 respectively). The rescue drug was required by 3 patients (6%) were in metoclopramide group, 4 patients (8%) in dexketoprofen trometamol group and one patient (2%) in the metoclopramide + dexketoprofen trometamol group. No side effects were observed in subjects in three treatment groups.

CONCLUSION

No significant difference in VAS was found between three treatment groups at the 15th minute, but metoclopramide + dexketoprofen trometamol was superior to both metoclopramide and dexketoprofen trometamol at the 30th min.

Serum obestatin and omentin levels in patients with diabetic nephropathy

INTRODUCTION

Diabetic nephropathy is the leading cause of chronic kidney disease and accounts for almost 45% of all new patients requiring renal replacement therapy. Omentin and obestatin, two novel proteins were suggested to be associated with insulin resistance, type 2 diabetes and cardiovascular risk factors. Thus, we postulated that they may also have an association with diabetic nephropathy which is known to be an independent cardiovascular risk factor. In order to investigate such an association we compared serum omentin and obestatin levels in type 2 diabetic patients with normoalbuminuria (NA) and macroalbuminuria (MA).

MATERIALS AND METHODS

A total of 81 type 2 diabetic patients were separated into two groups according to their proteinuria status; patients with NA (n = 39) and patients with MA (n = 42). Two groups were compared in terms of serum omentin and obestatin levels.

RESULTS

While s erum omentin levels did not differ among two groups (P = 0.407), serum obestatin levels were significantly higher in MA group (P = 0.001).

CONCLUSION

The results of this study showed that higher serum levels of obestatin were associated with macro albuminuria suggesting that obestatin may have a role in underlying pathogenic mechanisms that leads to diabetic nephropathy.

Evaluation of prophylactic and therapeutic effects of ruscogenin on acute radiation proctitis: an experimental rat model

Purpose

Radiation proctitis (RP) is inflammation and damage to the rectum, manifested secondary to ionizing radiation utilized for treatment. In this study, we evaluated the anti-inflammatory therapeutical and protective effects of ruscogenin in a model of acute RP.

Methods

Thirty-two Sprague-Dawley rats were divided into 4 groups (n = 8) as sham, control, treatment, and prophylaxis groups. Prophylaxis group and treatment group were dosed ruscogenin by oral gavage for 14 days pre- and postradiation. At the end of the 28th day, all subjects were sacrificed.

Results

Histopathological analysis showed a significant increase in cryptitis abscess, cryptitis and reactive atypia, and depth of lymphocytic infiltration of the control group, compared to the other groups (P < 0.05), while treatment and prophylaxis groups showed significant decreases (P < 0.05). Immunohistochemical analysis indicated that immunoreactivity were significantly higher in control group (P < 0.05, P < 0.001, and P < 0.01, respectively), but vice versa for treatment and prophylaxis groups. There was not any significant difference for fibroblast growth factor 2 immunoreactivity. The epithelium of control rectums indicated an increase in TNF-α immunoreactivity while other groups had significant decrease (P < 0.01). Electron microscopical findings were parallel to light microscopy.

Conclusion

In this study, ruscogenin was observed to be effective on prophylaxis or treatment of acute RP. Although there are various reports on the treatment of the rectum damaged by acute RP in the literature, this could be the first study since there is no research indicating the ultrastructural effect of ruscogenin.

Treatment of resistant idiopathic hiccups with pulse radio frequency on phrenic nerve and gabapentin: A case report

Hiccups affect life quality, career and family life when they become persistent. We present here a 54-year-old man who worked as a mason and a blacksmith with hiccups complaint for nearly one and a half years. In this period, he was admitted to emergency service ten times with fainting or almost fainting, cold sweating and hand stretching complaints. The patient expressed that he frequently threw up when he had hiccups and his social life was negatively affected. He reported that he was treated with baclofen, esomeprazole and hyoscine-n-butyl bromur without relief. He used escitalopram and chlorpromazine for a short time and quit because they negatively affected his sleeping. As he did not have any relief from medications, he refused any oral medical therapy including gabapentin and started to seek remedy from paramedical treatments resulted with no benefit. The patient was referred to algology department and an intervention on phrenic nerve with pulse radio frequency (8 minutes, 45 Volts, 20 milliseconds wavelength) was performed. Symptoms stopped immediately after the procedure but one week later, although the patient reported a significant decline in symptoms he still had hiccups. The patient was offered oral medical therapy again. With considerable relief from symptoms, the patient accepted oral therapy this time. Gabapentin 300 mg bid was prescribed. The symptoms were completely recovered and the patient reported no hiccups after 30 days of Gabapentin administration. Our case suggests that administration of gabapentin after pulsed radiofrequency might be effective for the treatment of persistent hiccups.

Parental beliefs and practices regarding childhood fever in Turkish primary care

BACKGROUND

Fever is a very common problem in pediatric age and is one of the most common reasons parents seek medical attention. We aimed to investigate beliefs, habits, and concerns of Turkish parents regarding their children's fever.

MATERIALS AND METHODS

We performed a cross-sectional survey which was conducted as face-to-face interviews by family physicians from April to June 2014 in family healthcare centers in nine different cities in Turkey. Parents with a child with fever aged between 0 and 14 years were interviewed. The participants were asked questions about sociodemographic data, the definition and measurement of fever, antipyretics, and other interventions used to reduce fever before presenting to the primary care center.

RESULTS

A total of 205 parents participated in this study. Ninety-four parents (45.8%) measured fever with a thermometer prior to presentation. Only 36 parents (38%) used the thermometer correctly. Thirty-eight parents (18.5%) knew the correct temperature definition of fever for the measured site. A mercury-in-glass thermometer was the choice for most parents (78%) and preferred site for measurement was axillary region (85%). The fever was treated prior to arrival by 171 parents (83.4%). Paracetamol was the most frequently used antipyretic. Fifty-four parents (31.5%) failed to administer the correct antipyretic dose, and 73 parents (42.6%) failed to give the antipyretics at proper intervals. One hundred and fifty-three parents (67%) believed that if not treated fever could cause convulsions.

CONCLUSION

We conclude that parents share important misconceptions about definition, treatment, and consequences of childhood fever and tend to treat fever before seeking medical care with a substantial rate of wrong doses and wrong intervals.

Nesfatin-1 alleviates extrahepatic cholestatic damage of liver in rats

Obstructive jaundice (OJ) can be defined as cessation of bile flow into the small intestine due to benign or malignant changes. Nesfatin-1, recently discovered anorexigenic peptide derived from nucleobindin-2 in hypothalamic nuclei, was shown to have anti-inflammatory and antiapoptotic effects. This study is aimed to investigate the therapeutic effects of nesfatin-1 on OJ in rats. Twenty-four adult male Wistar-Hannover rats were randomly assigned to three groups: sham (n = 8), control (n = 8), and nesfatin (n = 8). After bile duct ligation, the study groups were treated with saline or nesfatin-1, for 10 days. Afterward, blood and liver tissue samples were obtained for biochemical analyses, measurement of cytokines, determination of the oxidative DNA damage, DNA fragmentation, and histopathologic analyses. Alanine aminotransferase and gamma-glutamyl transferase levels were decreased after the nesfatin treatment; however, these drops were statistically non-significant compared to control group (p = 0.345, p = 0.114). Malondialdehyde levels decreased significantly in nesfatin group compared to control group (p = 0.032). Decreases in interleukin-6 and tumor necrosis factor-α levels from the liver tissue samples were not statistically significant in nesfatin group compared to control group. The level of oxidative DNA damage was lower in nesfatin group, however this result was not statistically significant (p = 0.75). DNA fragmentation results of all groups were similar. Histopathological examination revealed that there was less neutrophil infiltration, edema, bile duct proliferation, hepatocyte necrosis, basement membrane damage, and parenchymal necrosis in nesfatin compared to control group. The nesfatin-1 treatment could alleviate cholestatic liver damage caused by OJ due to its anti-inflammatory and antioxidant effects.

Metabolic and histopathological effects of sleeve gastrectomy and gastric plication: an experimental rodent model

Introduction

Obesity has recently become a major health problem, and researchers have been directed to work toward the development of surgical techniques, with new mediators playing an important role in nutrition. Gastric plication (GP) and sleeve gastrectomy (SG) have become popular recently. These are widely used techniques in bariatric surgery.

Objectives

In this study, we aimed to compare the efficiency of SG and GP techniques on rats.

Methods

Wistar-Hannover rats (n=18) were divided into three equal groups, namely SG, GP, and control. Blood samples were taken before the operation and on the 30th day after the operation. The weights of all rats were recorded both on first day and the 30th day after the operation. Serum gastrin, ghrelin, and leptin levels were also measured on the same days. For histopathological examination, gastrectomy was performed after the animals were sacrificed.

Results

Average weight loss was 10% for the SG group and 6.5% for the GP group. One month after the operations, the decrease in the ghrelin and leptin levels of GP and SG groups was significant compared with the levels of the control group. Gastrin levels of the SG group increased significantly compared with those of the control group. Histopathological examination revealed that there was significant decrease in the ghrelin and leptin levels of the GP and SG groups compared with those of the control group. Foveolar hyperplasia (FH), cystic glandular dilatation, and fibrosis were significantly higher in the GP and SG groups compared with the control group.

Conclusion

Although GP is not as effective as SG in terms of weight loss, it provides the same effectiveness in decreasing ghrelin and leptin levels. Histopathological findings revealed that FH, fibrosis, and the cystic glandular dilatation development rates were similar.

Isolated thyroid metastasis from renal cell carcinoma

Metastatic neoplasms of the thyroid are uncommon when compared to primary tumors of the gland. Renal cell carcinoma (RCC) is a highly aggressive tumor of the urinary system. It can spread all over the body. Isolated solitary metastases of RCC to the thyroid are very rarely observed. A 64-year-old woman with a history of left radical nephrectomy for RCC, was referred to our clinic with palpable thyroid nodule. Ultrasound confirmed the nodule on the left lobe. Histopathological examination of the thyroidectomy specimen revealed that there were two solitary metastasis of RCC. No other distant metastasis were detected. Metastatic tumors of the thyroid gland are very rare. When patients with thyroid nodule are referred to our clinic with the history of other malignancies, we must consider metastasis. Thyroidectomy is recommended in the case of isolated thyroid metastasis of RCC.

Preoperative chemotherapy for T2 breast cancer is associated with improved surgical outcome

BACKGROUND

The aim of this study is to compare the clinical outcome in T2 breast cancer patients who underwent preoperative chemotherapy (PC) and who did not. The study also tried to define a subgroup of patients, who are more beneficial after PC in terms of lower re-excision rates, better cosmetic results and local recurrence free survival.

MATERIALS AND METHODS

251 consecutive patients treated for nonmetastatic T2 invasive breast cancer were analyzed retrospectively. Of those; 141 underwent primary surgery (PS) followed by chemotherapy, whereas 110 were treated with combination of PC and surgery.

RESULTS

The patients who were treated with PC had a significantly higher incidence of negative margins and lower rate of re-excision (5% vs. 16%, p = 0.02). Of all patients attempted breast conserving surgery (BCS), patients in the PC group were more likely to undergo BCS as their definitive operation compared to patients with PS group (BCS rates; PC group: 99% vs. PS group: 92%, p = 0.05). Multifocal disease (OR: 7, 95% Cl, 2.7-18.4, p = 0.0001) and PC (OR = 0.2; 95% CI, 0.06-0.72, p = 0.01) were factors associated with margin positivity in patients treated with BCS. There was no statistically significant difference in 5 year local-recurrence free survival rates between 2 groups.

CONCLUSIONS

Our study shows that PC significantly decreases the re-excision in patients undergoing BCS with primary T2 breast tumors. This data suggests that any patient with a tumor greater than 2 cm might be considered for PC to increase BCS success with final negative margins.

Primary squamous cell carcinoma of the stomach

Primary squamous cell carcinoma of the stomach accounts for less than 1% of all gastric malignancies. Less than 100 cases were reported in the literature. Therefore, knowledge about management and prognosis of the disease is limited. Surgical approach is the basic form of treatment. In this study we confirmed a case of primary gastric squamous cell carcinoma with the aim of contribution to the literature, which is seen rare, and the diagnosis was confirmed pathologically.

Survival effect of supportive care services for Turkish patients with metastatic gastric cancer

BACKGROUND

Gastric cancer is the second most common cause of cancer- related deaths worldwide and ranks 11th or 14th among all deaths. Patients with advanced disease require supportive care along with the medical and/ or surgical treatment.

AIM

To assess the need for palliative care for patients with advanced tumours along with standard clinical therapy.

MATERIALS AND METHODS

Eighty-four patients with metastatic (stage 4) gastric cancer, including both patients who had received surgical treatment or not , were followed up in Bagcilar Training and Research Hospital, Division of Medical Oncology between 2011 and 2014. They were categorised as supportive care (-) (Group 1, n=37) and (+) groups (Group 2, n=47) and evaluated retrospectively.

RESULTS

Demographic characteristics of the patients were as follows: mean age, Group 1, 65.2±10.5 years, Group 2,63.7±11.3 years; male/female ratio, Group 1, 21/16, Group 2, 28/19; distribution of Eastern Cooperative Oncology Group (ECOG) performance scores of 0 and 1, Group 1, ECOG 0 (n=9) and 1 (n=14), Group 2, ECOG 0 (34) and 1 (n=13) (p<0.0001); patients receiving second-line, Group 1 (n=7) and Group 2 (n=22) (p<0.008) or third - line chemotherapy,Group 2 (n=6) (p<0.02); mortality rates, Group 1, (n=28; 75.6%) and Group 2 (n=30; 63.8%); progression-free survival (PFS) rates, Group 1, 17.4±6 weeks, Group 2, 28.3±16.2 weeks; statistically significant overall survival rates, Group 1, 20.8±8.2 weeks and Group 2, 28.3 ± 162 weeks (p<0.01).

CONCLUSIONS

The supportive care team (medical oncologist, general surgeon, internal medicine specialist, algologist, psychiatrist and radiologist) can play a role in the treatment of metastatic gastric tumours, with improvements shown in terms of the performance status of cases, eligibility of patients to be on chemotherapy programmes for longer duration and overall survival rates in Turkey.

Placental site trophoblastic tumor: report of a tertiary center experience

OBJECTIVE

To analyze the clinical and pathological characteristics of placental site trophoblastic tumor (PSTT) cases and to discuss the diagnosis, treatment, and prognosis of PSTT.

MATERIALS AND METHODS

The clinical and pathological data of eight patients with PSTT at Istanbul Medical Faculty Hospital from 1988 to 2010 were analyzed retrospectively.

RESULTS

The mean age of the patients was 31 years. The antecedent pregnancy was full-term delivery in most of the patients (6/8, 75%). The mean interval from last pregnancy to diagnosis of PSTT was 35 months (range, six to 192). Serum human chorionic gonadotropin (hCG) levels at the time of diagnosis ranged from 0.1 to 2280 mIU/ml (mean, 614). All patients had Stage 1 disease and ultimately underwent hysterectomy. None of the patients received adjuvant chemotherapy. One patient died of an unknown reason, one month after the surgery. The rest of the patients were alive and without evidence of disease after an average of 3.5 years (range, one to 11) of follow-up.

CONCLUSION

Hysterectomy alone can provide long-term survival in early-stage disease.

Drugs with anticholinergic side-effects in primary care

BACKGROUND

Anticholinergic drugs in elderly people have been associated with some serious side-effects. Patients in Turkey tend to attend primary care centers to have prescriptions of the drugs they chronically use. However, very little are known about how frequent that these drugs are prescribed and their side-effects in Turkish population. We aimed to investigate the usage and side-effects of drugs with anticholinergic properties in patients over 65 years of age attending to primary care centers.

MATERIALS AND METHODS

Five hundred and sixty-three subjects were interviewed with a questionnaire of 16 questions inquiring their medication and possible side-effects. Timed up and go test (TUGT) and standardized mini-mental test (SMMT) were also performed.

RESULTS

Medical records of 563 individuals were screened to detect anticholinergic medication. Twenty-eight patients were using anticholinergic medication. Mean duration of anticholinergic medication usage was 3.17 years. Mean number of falls occurred in the previous year was 1.14 ± 1.17. Mean SMMT score was 27.20 ± 1.13. Mean TUGT scores mean was 12.4 ± 1.25. Drowsiness in 18 patients (65%), dry mouth in 15 patients (53%), dry eyes in 15 patients (53%), constipation in 11 patients (39%), blurred vision in 11 patients (%39), urinary hesitancy in eight patients (28%), confusion in six patients (21%) were reported. We found that none of the subjects were evaluated in terms of fall risk or mental status by their doctors before the prescription of drugs with anticholinergic effects.

CONCLUSIONS

A suggested approach to improve drug safety was reported as to reduce the use of anticholinergic drugs when it is possible. Psychiatrists and family physicians should select less anticholinergic drugs for medication and have to evaluate their patients' fall risk and their cognitive status before prescribing drugs with anticholinergic side effects.

Placental mesenchymal dysplasia: a rare clinicopathologic entity confused with molar pregnancy

Placental mesenchymal dysplasia (PMD) is a rare placental abnormality characterised by placentomegaly and grape-like vesicles resembling partial mole by ultrasonography, but in contrast to partial mole can co-exist with a viable fetus. Although the karyotype is normal, the fetus is at increased risk for intrauterine growth restriction, intrauterine fetal demise or perinatal death and Beckwith-Wiedemann syndrome. Prenatal diagnosis is difficult and the final diagnosis is usually achieved by postpartum histological examination of the placenta. We present two recent cases of placental mesenchymal dysplasia with poor obstetric outcome. One fetus presented with reduced growth parameters, while the other fetus showed hepatosplenomegaly and early hydropic changes that appear to be associated with Beckwith-Wiedemann syndrome. In this report, the clinico-pathological features of two cases of PMD are discussed and the differentiation from a partial mole is highlighted. This study also supports the utility of cytogenetic ploidy analysis and p57KIP2 protein staining in the evaluation of pregnancies with PMD.

Elevated tissue levels of tumor necrosis factor-α in vulvar vestibulitis syndrome

The purpose of this study was to compare levels of inflammatory cytokines, namely TNF-α, IL-1β, and IL-1 receptor in women with vulvar vestibulitis syndrome (VVS) relative to levels in controls. The authors hypothesized that tissue concentrations of inflammatory cytokines would be elevated significantly in women with VVB compared to pain-free controls. The study population consisted of 15 women with strictly defined VVB in reproductive age and 13 age-matched women with no history of vulvodynia. For TNF-α, positive staining was observed in 40% of the samples from the study group and in 7.7% of the samples from the control group. The difference between the groups was statistically significant (p < 0.05). In conclusion, a limitation of the present study was the relatively small sam- ple size. However, the authors' intention was simply to propose that the local inflammation may be mediated by cytokines as TNF-α may rather than trying to single out a pathogenesis of VVS. The authors' findings of elevated TNF-α may suggest new therapeutic alternatives for VVS, as inhibiting cytokine synthesis or antagonism of the cytokine receptor.

Abstract P1-01-22: Which cytologically proven node-positive breast cancer patients can avoid axillary lymph dissection after neaodjuvant chemotherapy?

BACKGROUND:

It is still controversial whether axillary lymph node dissection can be omitted after negative sentinel lymph node biopsy in breast cancer patients with clinically positive axilla at presentation treated with neoadjuvant chemotherapy (NAC). The aim of this study was to analyze whether SLN biopsy could be useful in these patients.

METHODS:

After NAC of 112 patients with cytology-proven axillary node metastasis at the time of diagnosis, SLNB using radioisotope and blue dye was performed including completion node dissection between 2008 and 2012. The results of SLNB and clinicopathological characteristics were analyzed for correlation with pathological axillary lymph node status.

RESULTS:

SLN was successfully identified in 107 (95.5%) patients. Tumor nonresponse and extensive residual nodal disease were found to be significantly associated with detection failure of sentinel nodes. Axillary status was predicted with 94% accuracy and a false negative rate of 8.7%. Axillary nodal status before NAC (cN2 versus cN12) was associated with higher false-negative rates (p = 0.02). Conversion to node-negative disease was achieved in 38 (35%) patients: 23% of patients with the luminal A subtype, 12% of patients with the luminal B, 39% of patients with the HER2-enriched, and 26% of patients with the triple-negative breast cancer subtype. The tripple negative and HER2-enriched breast cancer subtypes had a significantly better false negative rate and accuracy.

CONCLUSIONS:

SLNB was found to be technically feasible, but its routine use was not recommended for LABCs after NAC. However, acceptable performance was noted for tripple negative and HER2-enriched breast cancer patients presented with N1 axillary status in the beginning of NAC, and thus SLNB might be safely considered in these selected patients.

Abstract P4-07-08: The predictive and prognostic role of tumoral miRNA expression levels in patients with breast cancer (BC) treated with neoadjuvant chemotherapy (NAC)

Over the last decade, miRNA's have gained considerable interest due to the accumulating evidence regarding their relevant regulatory functions on cancer initiation, proliferation and progression. Furthermore, there are data showing that miRNA's can have a predictive role in response to NAC. The aim of this study is to evaluate the association between miRNA expression profile and response to NAC in patients with BC. 21 patients who received NAC consisting of 4 cycles of antracycline and cyclophosphamide (EC), followed by 4 cycles of docetaxel (T) were included in this study. Tumor core biopsies and blood specimens were collected before initiation, before the 5th cycle and after the completion of NAC for pathologic evaluation, miRNA expression and circulating correlative miRNA levels. The miRNA profile consisted of 9 miRNA's that were previously shown to be related to anthracycline and taxane resistance, as well as those associated with various intracellular functions. Associations with miRNA expression and clinical and pathologic variables, including response were evaluated by the Spearmann Correlation test. Response assessment was carried out every couple of cycles by physical examination, and radiologic evaluation after 4 and 8 cycles, respectively. Clinical response to EC was complete regression in 4.76% (n:1), PR in 66.7% (n:14), minimal response in 23.8% (n:5); and progression in 4.76% (n:1); all patients responded to docetaxel with 1 having CR and 20 PR. Pathologic response evaluation revealed CR in 7 patients (33.3%), good PR (defined as more than 50% regression in the viable tumor cells) in 8 (38.1%) and minimal PR in 6 (28.6%). Baseline levels of miRNA expression before initiation of NAC from the lowest to the highest level were as follows: miR10b (mean relative value (MRV): 0.24), miR-200c, miR34a, miR-11, let7a, miR-200c, miR-21, miR-195 and miR-221 (MRV: 132.5). Although each miRNA tested were in positive correlation with each other (p&lt;0.05), there was no association with any miRNA with known clinic-pathologic variables, such as ER, PR, Her-2/neu or Ki67 levels. All miRNA's showed higher levels in patients presenting with stage 2 disease compared to those with stage 3 disease, which was marginally significant for miR-155 and miR-21 (p:0.05). After 4 cycles of EC miR-21 and miR-195 expression decreased significantly (mean decrease 500 times the initial level) (p&lt;0.05), which was more evident in patients with earlier stage at presentation (stage 2 versus stage 3 disease (p:0.03)). There were no significant correlations seen with any miRNA and response to taxane-based NAC, since all patients showed a response. Furthermore, there was no correlation between pCR and the miRNA's tested. Nevertheless, there was a trend for higher pre-treatment miR-34 levels predictive for a good clinical response to EC, which was defined as more than 50% regression in the largest tumor diameter (p:0.07). In this preliminary study, we have shown that a substantial decrease in miR-155, -21,and -195 expressions after 4 cycles of EC may be associated with clinical response to anthracycline-based NAC. Furthermore, a higher miR-34 expression may predict for athracycline responsiveness.

Primary cyst hydatid in the neck; report of one case

Hydatid cyst is a parasitic disease that has been recognized endemically in many countries. Although the liver and lung are the most common organs involved by the disease, it may appear rarely in other tissues as a primary disease. In the ultrasonography of the neck taken from a 17 year old case who attended with a complaint of swelling in the neck, a partly regular, bounded cystic lesion of 33x28 mm in size was reported. When the cyst was thought to be hydatid during surgical exploration, this diagnosis was confirmed by histopathological verification of the specimen obtained. Whole abdomen ultrasonography and PA Chest Radiography were taken in order to determine whether there was another focus during the postoperative period. The Echinococcus ELISA test was performed as an immunological parameter. Treatment with Albendazole began after diagnosis during the postoperative period. Although hydatid cyst most commonly involves the liver and lung, it may be detected in all body tissues. Therefore hydatid cyst must be considered in the differential diagnosis in cystic lesions that are rarely encountered in body localizations in human, living in endemic regions.

[Comparison of the hemostatic efficiency of Ankaferd Blood Stopper and fibrin glue on a liver laceration model in rats]

BACKGROUND

Ankaferd Blood Stopper® (ABS) is an organic topical hemostatic agent that has become available in recent years. The aim of this study was to compare the effectiveness of ABS in a liver laceration model in rats with that of fibrin glue (FG), which is currently being used widely in clinics.

METHODS

Thirty-two Wistar Albino type rats were randomly divided into four groups. In the Sham group (Group 1), only the liver was explored. In the other study groups (Groups 2, 3 and 4), three incisions were performed, each 1 cm long and 2 mm deep, on the front of the left lobe of the livers. In Groups 2 and 3, ABS and FG were used as hemostatic agents, respectively. No materials were used for the injuries in the Control Group (Group 4). Bleeding periods, changes in the hematocrit levels, intraabdominal adhesion levels, and histopathological effects were taken into consideration.

RESULTS

There was no significant difference between the period of hemostasis in Groups 2 and 3, whereas the same period was evidently longer in Group 4 (17 (15-20) sec, 18 (16-20) sec, 70 (64-74) seconds, respectively; p<0.05). No significant difference was detected between the groups regarding intraabdominal adhesion levels (Group 1: 1 (0-1), Group 2: 2 (1-3), Group 3: 2 (1-3), Group 4: 2 (1-3); p>0.05). Microscopic evaluations revealed similar histopathological effects of ABS and FG on the liver and surrounding tissues (p>0.05).

CONCLUSION

The topical hemostatic effectiveness of ABS was shown to be comparable to FG in a liver laceration model in rats. There was no significant difference between these materials regarding adhesion formation in intraabdominal use or histopathological effects.
