Side Effects Related to BNT162b2 and CoronaVac Vaccine Requiring Emergency Department Visit

Background  Currently, the most effective method in the fight against coronavirus disease 2019 (COVID-19) is vaccination against the disease. However, there are hesitations among society concerning the safety and side effects of COVID-19 vaccines. We aimed to determine the observed side effects that require an emergency room visit after taking the BNT162b2 and CoronaVac vaccines.

Methods  This prospective observational study was conducted with patients who presented to the emergency department due to vaccine-related complications after COVID-19 vaccination. The patients' symptoms at the time of presentation, time from vaccination to the onset of symptoms, and dose of the vaccine administered were determined. In addition, the demographic characteristics of the patients, whether they had a history of COVID-19 infection, and their vital signs at the time of presentation were recorded. The variables were compared according to the type of vaccine administered.

Results  The study included 182 patients who presented to the emergency department over a 6-month period. It was determined that 166 of these patients (91.2%) had received the BNT162b2 vaccine and 16 (8.8%) had received the CoronaVac vaccine. The majority of the patients did not have a history of COVID-19 infection (70.3%), and most presented to the hospital with complications after the second dose (61%). The onset of vaccine-related symptoms was mostly within 1 to 12 hours (39%). The majority of patients (97.8%) were discharged from the emergency department. The most common symptoms after vaccination were fatigue ( n  = 70), followed by muscle/joint pain ( n  = 52), headache ( n  = 33), and fever ( n  = 32). The rate of dizziness was found to be statistically significantly higher in the CoronaVac vaccine group than in the BNT162b2 vaccine group ( p  = 0.008). There was no statistically significant difference between the two vaccine groups in relation to the remaining symptoms ( p  > 0.005).

Conclusion  There were no serious complications related to the BNT162b2 or CoronaVac vaccine. The most common symptom after both vaccines was fatigue; therefore, the BNT162b2 and CoronaVac vaccines can be safely administered.

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.

Transcutaneous electrical nerve stimulation (TENS) for the treatment of renal colic in the emergency department: A randomized, double-blind, placebo-controlled trial

STUDY OBJECTIVE

To determine the analgesic efficacy of TENS treatment in patients with renal colic in the emergency department (ED).

METHODS

This double-blind, randomized controlled trial was conducted in a tertiary care ED. Patients with a definitive diagnosis of renal colic were assigned (1:1) as randomized to receive the real TENS with frequency 100 Hz, pulse width 200 microseconds, voltage 2 mA, or placebo with sham TENS. Pain intensity was measured using visual analog scales (VAS) at baseline, after 15 and 30th minutes.

RESULTS

A total of 100 patients were included in the final analysis: 50 patients treated with real TENS and 50 patients treated with sham TENS. VAS scores in both groups were similar at baseline. The mean reduction in VAS score at 15 min was 33.3 ± 17.6 (95% Confidence interval (CI): 28.3 to 38.3) for the real TENS group and 14.9 ± 11.6 (95% CI 11.6 to 18.2) for the sham TENS group (mean difference: 18.4 (95% CI: 12.5 to 24.4, P < 0.0001). The mean reduction in VAS score at 30 min was 63.7 ± 21.1 (95% CI: 57.7 to 69.7) for the real TENS group and 14.9 ± 16.2 (95% CI: 19.5 to 10.3) for the sham TENS group (mean difference: 48.8, 95% CI: 41.4 to 56.3, P < 0.0001). Four patients (8%) in the real TENS group and 24 patients (48%) in the sham TENS group required the rescue medication after 30th minutes.

CONCLUSIONS

TENS is effective for acute pain treatment in renal colic patients in the ED. TENS therapy could be a treatment option for renal colic.

Use of infrared thermal camera in acute scrotal pain: a prospective study

Background and objectives: Infrared thermal (IR) camera is used to assess various clinical conditions such as diabetic foot, carotid artery stenosis, and superficial infection. The present study was designed to determine the usefulness of IR thermal camera in scrotal temperature measurement before color Doppler ultrasonography (CDUS) in patients admitted to the emergency department with acute scrotal pain. Method: This study was prospectively conducted on 49 patients with acute scrotal pain and 30 control participants. The findings of CDUS and scrotal temperature measurements by an IR camera were separately evaluated by different physicians. In all patients, temperature measurements with IR camera were made under the same environmental conditions. Results: Of the 49 patients included in the study, four were diagnosed with torsion, 12 with epididymitis, 4 with orchitis, 3 with epididymo-orchitis, and 2 with varicocele. A significant difference was observed between the scrotal temperature of the patients with scrotal pain and the mean testicular temperature of the control group based on the IR camera measurement (p<0.05). IR camera did not detect any difference between the two testicles of the same person in the patient group (p=0.615). Although the lowest temperature was in testicular torsion, the patients’ scrotal temperature did not significantly differ according to their diagnoses (p=0.087). Conclusion: Testicular temperature measured by IR device was lower in patients presenting with scrotal pain compared to normal individuals. Although not statistically significant, the lowest temperature was found in cases of testicular torsion. IR camera may be useful in triage when used in conjunction with physical examination in patients presenting with acute scrotal pain.

Analysis of genitourinary trauma patients admitted to the emergency department

Background and objective: Genitourinary injuries are commonly encountered in the emergency department but may be over looked in case of multi-trauma. Determining the clinical features of genitourinary injuries will help physicians in the management of genitourinary trauma. Methods: The study was conducted in a tertiary hospital. Patients of all ages, admitted in the emergency department, with trauma between 2015 and 2020 were included and analyzed. The cause of genitourinary trauma, affected organs, any accompanying injury, treatments, mortality status, and laboratory tests related to mortality were obtained from the hospital records and analyzed. Results: During the study period, 87 patients admitted to the emergency department with genitourinary trauma were included in the study. The majority of these patients (n=79) were male. Of the patients, 9.2% died. All the patients in the mortality group had additional injuries. The most frequently injured organ was determined as the kidney (51.7%), followed by the scrotum (25.3%) and penis (8.1%). Additional injuries were observed in 81.6% of the patients. Intra-abdominal organ injuries (19.5%) were the most common accompanying injuries. White blood cell count (WBC), aspartate aminotransferase (AST), alanine aminotransferase ( ALT), blood glucose and creatinine values measured at the time of admission to the emergency department were found to be higher in the non-survivor group. The majority of the patients (81%) were discharged with conservative treatment and follow-up. Conclusion: It was determined that genitourinary injuries were frequently seen with additional injuries. Genitourinary injury should be evaluated carefully, especially in the presence of intra-abdominal organ injuries. Ibrahim Med. Coll. J. 2021; 15(2): 32-37

Violence toward emergency physicians: A prospective-descriptive study

BACKGROUND

The highest rate of workplace violence occurs in the health sector, although most cases remain unreported. Emergency services face the majority of these incidents for many reasons, such as the patient profile, long waiting time, and overcrowding. We aimed to determine the characteristics and causes of violence toward emergency physicians.

METHODS

The acts of violence toward emergency physicians over a one-year period were prospectively recorded. After a violent incident took place, a third party separately interviewed the physician exposed to the violent behavior and the perpetrator who displayed this behavior. We examined the perpetrator's reasons for violence, their demographic characteristics, and the medical complaints of patients involved in such events to determine the characteristics and causes of violence.

RESULTS

Of the violent acts investigated, 85.1% were verbal, and most were directed toward male doctors by the young male relatives of the patients. More than half of the violent acts occurred within the 15 minutes of presentation to emergency service (60.5%) and at off-hours (69.4%). Concerning the health insurance, 20.4% of the cases were covered by the free green card system, and a small number of the perpetrators of violence lived in rural areas (38.2%). The most common reason for violent behavior was the patients' or their relatives' dissatisfaction with the examination or treatment method (38.2%).

CONCLUSIONS

Appropriate communication should be established with the patients, and they should be adequately informed about the treatments and interventions to be performed in order to prevent possible acts of violence.

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.

Comparison of non-invasive CPAP with mask use in carbon monoxide poisoning

BACKGROUND

Carbon monoxide (CO) is one of the major causes of poisoning worldwide. We aimed to investigate the efficacy of the continuous positive airway pressure (CPAP) use in CO poisoning.

METHODS

After CO poisoning, one group of patients was treated with a non-rebreather mask (NRB) and another group using the CPAP mode of mechanical ventilation (CPAP). All patients received at least 90 minute treatment. The carboxyhemoglobin saturation (SpCO) levels of all patients were measured from the fingertips with a portable CO-oximeter at 0, 30, 60 and 90 min. The rates of changes in the serially measured SpCO values were obtained using the Wilcoxon signed-rank test.

RESULTS

A total of 45 patients (24 in NRB and 21 in CPAP group) completed the study. The median initial SpCO levels were 24% (21-33) in NRB group, 25% (21-32) in CPAP group, with no statistically significant difference (p 0.323). At the 30th, 60th, and 90th minutes of treatment, significantly lower values were obtained from CPAP than NRB (p < 0.001). The COHb half-life was decreased significantly by CPAP [105(70-190) vs 45(30-120), p < 0.001]. In CPAP group, the fastest decline in the SpCO level was observed for the interval of 0-30 min [Median difference: 8(3-14), p < 0.001].

CONCLUSIONS

CPAP lowered the amount of CO in the blood faster than the mask; therefore, it may be effective in the treatment of CO poisoning.

Prevalence of attention deficit hyperactivity disorder (ADHD) in children presenting with foreign body ingestion

BACKGROUND

Foreign body ingestion is a common condition in children. We aimed to compare the incidence of attention deficit hyperactivity disorder (ADHD) symptoms in children that ingested foreign bodies with healthy children.

METHODS

The study group consisted of 3- to 17-year-old pediatric patients admitted to the emergency department after foreign body ingestion, and the control group was formed with children having similar demographic and cultural characteristics that presented to the same department for non-traumatic causes. After initial intervention and stabilization, we administered the Conners' Parent Rating Scales-Revised (CPRS-R) to both groups.

RESULTS

The study group consisted of 53 patients with a mean age of 7.83 ± 4.36 and the control group comprised 47 children with a mean age of 7.72 ± 3.48 years. There were no statistically significant differences between the study and control groups in terms of age, gender, and parental education levels (p > 0.05 for each). The foreign objects most ingested by children were coins (32.1%), followed by needles (15.1%) and beads (9.4%), and all the patients recovered without complications and were discharged. All the CPRS-R subscale scores were significantly higher in the study group than in the control group (p < 0.001). The parental education levels of the study group were not significantly correlated with DSM-IV hyperactivity-impulsivity and DSM-IV total.

CONCLUSION

We found that the incidence of ADHD symptoms may be high in children referred to emergency services after accidentally ingesting foreign bodies.

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.

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.

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.

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.

Analysis of complaints lodged by patients attending a university hospital: a 4-year analysis

OBJECTIVE

Health practitioners often regard complaints concerning the quality of patient care in a negative light. However, complaints by patients and their relatives are an important source of information when considering ways in which to improve care. In the present study, we evaluated the complaints of patients and their relatives with regard to our hospital, such that we could take adequate remedial measures.

METHOD

Records of all patient complaints made between June 2008 and June 2012 were retrieved from the archives of the Quality Improvement Unit. The socio-demographic profiles of complainants, and their reasons for complaining, were analyzed using the SPSS statistical package.

RESULTS

The results revealed that 453 complaints, relating to medical care, the attitude of staff, waiting times, and financial issues, were made against our hospital over 4 years. Of the complainants, 68.9% (n = 312) were male, and 31.1% (n = 141) were female. The majority (16.3% and 20.4%, respectively) of the complaints were due to medical care and staff attitude problems. The unit about which most patients complained was hospital administration (22.1%), and one hundred fifty-three (33.8%) complaints were about physicians. Complaint frequency was 0.22 per 1.000 visits.

CONCLUSION

Complaints may be potentially useful quality assurance tools, and can identify system flaws. The primary causes of complaints were medical care, attitude of the staff, and waiting time, and many of these issues may be remedied.

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.

Therapeutic red cell exchange for severe carbon monoxide poisoning

BACKGROUND AND OBJECTIVE

Carbon monoxide (CO) is the most common cause of fatal poisoning worldwide. Therapeutic red cell exchange (TREX) has been used in the treatment of many different diseases. Therefore, we aimed to evaluate the efficacy of TREX on the clinical status, outcome, and discharge of patients with severe CO poisoning.

METHODS

Demographic data, clinical status, and outcomes of 12 patients that were treated with TREX for severe CO poisoning after referral to the Emergency and Hematology Departments of Gaziantep University between November 2011 and April 2012 were evaluated.

RESULTS

Mean carboxyhemoglobin level decreased from (59.7 ± 12.7)% (38-79%) to (17 ± 9.4)% (8-43%), and mean Glasgow Coma Scale score increased from 4 ± 1.6 (3-8) to 9.4 ± 3.5 (3-14) after TREX therapy. Five patients were admitted to the intensive care unit. Rhabdomyolysis developed in one case. Of the 12 patients, 11 were discharged alive, and one patient died.

CONCLUSION

TREX may be an alternative treatment method for reducing mortality and morbidity in cases of severe CO poisoning.

Malignant germ cell tumors of the ovary: a review of 41 cases and risk factors for recurrence

OBJECTIVE

To review the outcome of treatment in patients with malignant ovarian germ cell tumors and to define the risk factors for recurrence.

MATERIAL AND METHODS

Forty-one patients with malignant ovarian germ cell tumors were reviewed retrospectively. Survival time and survival rate were obtained. Risk factors such as stage, histological type, and type of operation were evaluated for reccurrence.

RESULTS

Twenty-three (56%) had dysgerminomas, eight (19.5%) had mixed germ cell tumors, three (7.3%) had yolk sac tumors, three (7.3%) had immature teratomas, two (4.8%) had squamous cell carcinoma arising from a mature teratoma, one (2.4%) had embryonal carcinoma and one choriocarcinoma. Most of the cases (73%) were in Stage I. Twenty-nine patients (70.7%) underwent conservative surgery and 12 patients (29.3%) had at least bilateral salpingo-oophorectomy. Thirty patients were operated on optimally with surgical staging and 11 suboptimally. Seven patients (17%) had recurrence after remission. The overall survival time was 187 +/- 8.43 months for all cases, 195 +/- 8.49 for dysgerminoma and 161 +/- 10.96 for non-dysgerminoma cases with a median follow-up time of 98.52 (8-204) months. Non-dysgerminoma histologic type, being operated on suboptimally and radically, and advanced tumor stage have been found to be risk factors for recurrence.

CONCLUSION

Regardless of histologic types and stages the prognosis of germ cell tumors are satisfactory with current therapeutic strategies.

Interactive neuromonitoring methods of cochlea and auditory nerve during induced hypoxia and nerve manipulation

Methods and instrumentation were developed to monitor cochlea and auditory function during surgery. The system allows real time assessment of the cochlear function during auditory nerve manipulation. A specially designed optic probe, placed on the round window (RW) niche, enables simultaneous acquisition of cochlear blood flow (CBF) and electrocochleogram (ECochG). We developed the acquisition paradigms, signal processing methods and implement them in a computational platform. The neuromonitoring system performs an automatic extraction and analysis of cochlear microphonics (CM), compound action potentials (CAP) and sura mating potential (SP). The system uses envelope detection filters to detect the amplitude of the CM. The CAP signal is processed with zero phase shift spectral filters, tuned to enhance the action potential onset, which is sometimes embedded within the sura mating potential. An automatic peak detection and tracking algorithm is then applied to extract latency and amplitude of CAPs. Long-term assessment of the monitoring system was performed during experimental animal surgeries. The system allowed detailed study of the dynamics of CM, CAP and CBF during nerve manipulation and compression.

Ovarian clear cell adenocarcinoma producing alpha-fetoprotein: case report

BACKGROUND

Alpha-fetoprotein (AFP) is a useful tumor marker for germ cell tumors of the ovary and is valuable for both diagnosis and follow-up. However, it is very rare for an epithelial ovarian carcinoma to secrete AFP.

CASE

We report a case of a 63-year-old woman with a ovarian clear cell carcinoma with serous component of less than 10%. Both histological components were producing AFP as demonstrated by immunohistochemistry. After surgery and chemotherapy, AFP decreased to normal range. The patient also had elevated CA-125 levels but the tumor was negative for CA-125 which suggested the increased CA-125 might have been due to the associated ascites.

CONCLUSION

Ovarian clear cell type carcinomas rarely secrete only AFP and it might be the single marker that could be used in follow-up.

Radiation-induced benign glandular cells in posthysterectomy smears: a cytomorphologic and clinical analysis

In this retrospective study, we aimed to investigate the frequency and cytomorphologic characteristics of benign glandular cells (BGCs) in hysterectomized individuals. We also discussed the possible effect of radiation therapy on these cells. We reviewed our cytopathology archive material through a 5.5-year period and found 1460 posthysterectomy vaginal smears. Of these, 508 smears were from patients who had undergone hysterectomy for a gynecological malignancy. Review of this vaginal cytology material revealed 17 posthysterectomy patients whose smears contained BGCs. We obtained detailed clinical information in 16 of these. In addition to routine Papanicolaou staining, mucicarmine stain was also used to demonstrate cytoplasmic mucin in some cases. All the patients had a history of gynecological malignancy and had radiation therapy. Glandular cells appeared singly or in rows and honeycomb groups and did not show cytologic atypia. We concluded that radiation might give rise to a metaplastic process in which basal cells of squamous epithelium of the vagina transform into glandular cells. Most probably this process is independent of radiation dosage and period and is irreversible. We also propose that the possibility of encountering glandular cells in posthysterectomy smears is higher than expected, if the mucin stains have been used for the microscopic examination.

Gabapentin: an alternative to the cyclooxygenase-2 inhibitors for perioperative pain management

The cyclooxygenase-2 inhibitor, rofecoxib, was a popular analgesic adjuvant for improving perioperative pain management. We designed this placebo-controlled study to test the hypothesis that gabapentin could produce similar reductions in postoperative pain and opioid analgesic usage, thereby improving the recovery process. One hundred patients undergoing abdominal hysterectomy procedures were randomly assigned to one of four treatment groups: 1) control group received placebo capsules and pills before and for 2 days after surgery, 2) rofecoxib group received 50 mg/d PO and placebo capsules before and after surgery and, 3) gabapentin group received 1.2 g/d PO and placebo pills before and after surgery, and 4) combination group received rofecoxib 50 mg/d and gabapentin 1.2 g/d PO before and after surgery. The anesthetic technique was standardized and the postoperative assessments included verbal rating scales for pain and sedation, IV morphine usage, quality of recovery assessment, recovery of bowel function, resumption of normal activities, and patient satisfaction with their pain management. Postoperative pain scores were significantly reduced in all three analgesic treatment groups (versus control group). Compared with the control group, patient-controlled analgesia morphine usage was also significantly reduced in the 3 analgesic treatment groups at 1, 8, 24, and 30 h after surgery. Total PCA morphine usage was decreased by 43%, 24%, and 50% in groups 2, 3, and 4, respectively, compared with group 1. Oral analgesic consumption was also smaller in groups 2 and 4 when compared with the control group. The opioid-sparing effects of rofecoxib and gabapentin lead to a faster recovery of bowel function. Discharge eligibility scores in groups 2 and 4 were improved at 24 h when compared with group 1, and patient satisfaction with postoperative pain management was significantly higher at 24 h in all 3 analgesic treatment groups. At the 72 h follow-up, all of the patients in group 4 were completely satisfied with their pain management compared with only 32%, 64%, and 72% in groups 1, 2, and 3, respectively. Gabapentin (1.2 g/d PO) appears to be an acceptable alternative to rofecoxib (50 mg/d PO) for short-term use as an adjuvant to opioid analgesics in patients undergoing lower abdominal surgery.

Granulomatous villitis formed by inflammatory cells with maternal origin: a rare manifestation type of placental toxoplasmosis

We present a case of placental toxoplasmosis with granulomatous villitis. The patient was a 26-year-old gravida 1 female with the findings of intrauterine death at 16th week of gestation. The pregnancy was terminated. Pathological examination revealed an autolysed fetus and a placenta with necrotizing granulomas within the villous stroma. Encysted Toxoplasma gondii was rarely observed within the granulomas and serologic examination of the mother confirmed acute toxoplasmosis. A fluorocein in situ hybridization examination, using sex chromosome probes, revealed that the villous granulomas were formed by inflammatory cells, originated from the maternal immune system. In conclusion, T. gondii should be taken into consideration as a rare cause of placental granulomatous inflammation. To the best of our knowledge, this is the first case of granulomatous villitis due to toxoplasmosis, in which formation by maternal inflammatory cells has been demonstrated.

Identification of extracellular enzyme producing thermophilic bacilli from Balcova (Agamemnon) geothermal site by ITS rDNA RFLP

AIMS

Molecular characterization of extracellular enzyme producing thermophilic bacilli from Balcova geothermal site.

METHODS AND RESULTS

Three types of geothermal samples were collected: mud, re-injection water, and samples from uncontrolled hydrothermal vents. Isolates grown at 55 degrees C in culture media prepared in sterilized re-injection water, were screened for extracellular enzyme activity by using eight different substrates: casein, carboxymethylcellulose, pectin, polygalacturonic acid (PGA), soluble starch, Tween 20 and 80, and xylan. In total, 109 thermoaerophilic isolates were selected. All of the isolates could hydrolyse Tween 20 (100%) but not Tween 80. Soluble starch was hydrolysed by 96%, casein by 55%, xylan and carboxymethylcellulose by 9%, and pectin and PGA by 2% of the isolates. The isolates were grouped into 14 different homology groups by the restriction pattern analysis of 16S-internal transcribed spacer (ITS) rDNA RFLP. Each of the RFLP groups was also studied by 16S rRNA gene partial sequence analysis. Plasmid DNA profiles revealed that 15 of the isolated strains contained small plasmid DNA molecules ranging in size from 12 000 to 35 000 bp.

CONCLUSIONS

Combined analysis of 16S-ITS rDNA RFLP and 16S rRNA gene partial sequence results indicated the presence of novel or existing species of Anoxybacillus (nine species) and Geobacillus (three species).

SIGNIFICANCE AND IMPACT OF THE STUDY

In this study 16S-ITS rDNA RFLP was applied for the first time to differentiate thermophilic bacilli. It was also the first study on thermophilic bacilli of Balcova geothermal site.
