Benefits of treatment with favipiravir in hospitalized patients for COVID-19: a retrospective observational case-control study.

BACKGROUND: Although more than a year past since COVID-19 was defined, there is no specific treatment yet. Since COVID-19 management differs over time, it is hard to determine which therapy is more efficacious. In this study, we aimed to evaluate the efficacy of the regimen with Favipiravir (FPV) and determine if the timing of FPV addition offers any improvement. METHODS: A retrospective observational case-controlled cohort study was performed between March and September 2020, including adults with COVID-19 in a single-center in Turkey. We categorized patients into age-sex matched three groups, group 1 (n = 48) and group 2 (n = 48) included patients treated with the combination of FPV plus Hydroxychloroquine (HQ) early and late, respectively. Group 3 (n = 48) consisted of patients on HQ monotherapy. In Group 2, if the respiratory or clinic condition had not improved sufficiently, FPV was added on or after day 3. RESULTS: We found that starting FPV early had an impact on PCR negativity and the progression of the disease. 'No progression' was defined as the absence of a new finding in the control radiological examination and the absence of accompanying clinical deterioration. Also, the decrease in C-reactive protein (CRP) was greater in Group 1 than Group 3 (p < 0.001). However, we found that early initiation of FPV treatment did not have a positive effect on the estimated survival time. CONCLUSIONS: According to this retrospective study results, we believe that for better clinical outcomes, FPV treatment should be started promptly to enhance antiviral effects and improve clinical outcomes.

Does septoplasty affect 24-h ambulatory blood pressure measurements in patients with type 2 and 3 pure nasal septal deviation?

PURPOSE: To investigate day, night and 24 h all blood pressure effects of septoplasty by comparing pre- and post-operative 24-h ambulatory blood pressure monitoring (ABPM) values of NSD patients undergoing septoplasty. MATERIALS AND METHODS: The prospective study included 20 patients with type 2 and 3 pure NSD (mean age, 23.60 ± 6.51) who underwent septoplasty in our clinic. Nasal obstruction symptom evaluation (NOSE) questionnaire was applied to each participant both pre- and post-operatively to evaluate their views on the severity of NSD and the effectiveness of surgical outcomes. A comprehensive ABPM examination was performed both 2 days before surgery and at three months postoperatively for each patient and the findings were compared among patients. RESULTS: Preoperative NOSE score was 87.75 ± 7.34% and the postoperative score was 12.50 ± 6.58% (p = 0.000). Following septoplasty, 24-h systolic blood pressure (24SBP) declined from 119.4 ± 9.9 mmHg to 112.2 ± 8.0 mmHg (p = 0.000), daytime SBP (DSBP) declined from 125.9 ± 11.0 mmHg to 117.9 ± 8.4 mmHg (p = 0.000), nighttime SBP (NSBP) declined from 112.7 ± 9.5 mmHg to 105.5 ± 7.9 mmHg (p = 0.000), 24-h pulse pressure (24PP) declined from 46.7 ± 10.1 mmHg to 44.0 ± 8.4 mmHg (p = 0.015), and mean daytime PP (DPP) declined from 46.9 ± 9.7 mmHg to 44.6 ± 8.6 mmHg (p = 0.026). CONCLUSION: The decline in NOSE percentages following septoplasty demonstrated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to NSD may affect ABPM measurements. Moreover, the significant decrease in the 24SBP, DSBP, NSBP, 24PP and DPP following septoplasty showed that NSD may cause cardiovascular risk and this risk may be prevented by septoplasty.

Does omalizumab treatment affect serum dehydroepiandrosterone sulphate levels in chronic idiopathic urticaria?

INTRODUCTION: It is known that serum dehydroepiandrosterone sulphate (DHEA-S) levels are low in patients with chronic idiopathic urticaria. AIM: In the study, the effect of the drug on the DHEA-S serum levels and its correlation with the remission and relapse times of the disease was investigated. MATERIAL AND METHODS: Fifty-seven patients with chronic idiopathic urticaria who were referred to our hospital and 20 healthy volunteers were included in the study. A subcutaneous injection of 300 mg omalizumab was administered to the patient group. Drug injections at this dose were completed (6 injections in total, one per month). Relations between serum DHEA-S levels and relapse rates, treatment response and remission duration of the patients and control group were investigated in the groups. RESULTS: Median DHEA-S value before treatment was 116.3 (21.5-448.7) µg/dl; the median DHEA-S value measured after 3 months was 98.4 (10.0-410.0) µg/dl (p = 0.003). The median DHEA-S value before treatment was 123.1 (21.5-299.6) µg/dl when the initial and 3-month DHEA-S levels of the 34 complete remission patients were compared; after 3 months the value was 100.4 (23.1-301.9) µg/dl (p = 0.021). CONCLUSIONS: This is the first study to investigate the effect of omalizumab treatment on DHEA-S levels in the treatment of chronic urticaria according to our literature review. The DHEA-S levels were found to be significantly lower after omalizumab therapy but not related to remission and relapse times.

Can Biologic Agents Improve Treatment Success in Obese Patients With Psoriasis Vulgaris: A Retrospective Review of 320 Patients With Psoriasis Vulgaris.

INTRODUCTION: Obesity plays a major role in the development of many inflammatory disorders including psoriasis. OBJECTIVES: We aimed to demonstrate how treatment responses change according to body mass index (BMI) among patients with psoriasis. METHODS: In our study, Psoriasis Area and Severity Index (PASI) 75 and PASI 90 responses were assessed at baseline and at months 1 and 3 among patients who received TNF-α inhibitors, ustekinumab, IL-17 blockers, and IL-23 blockers. The same responses were also assessed with methotrexate and acitretin for a comparison group. Analyses were performed retrospectively. RESULTS: The study included 317 patients who received 222 biological and 95 conventional treatments. In the group with BMI ≥30, the proportion of patients who achieved PASI 75 response was 40.0% (N = 26) at month 1 and 55.4% (N = 36) at month 3. The proportion of patients who achieved PASI 90 response was 33.8% (N = 22) at month 1 and 44.6% (N = 29) at month 3 among those receiving biological agents. Improvement was significantly more difficult among obese patients. The proportion of patients who achieved PASI 75 response was 3.6% at month 1 and 25.0% (N = 7) at month 3 among patients receiving conventional systemic treatments. While the presence of joint involvement affected the success of treatment among obese patients with psoriasis, no relationships were found for smoking, the presence of concomitant psychiatric diseases, or the presence of pruritus in psoriasis. CONCLUSIONS: Biological agents were more successful in achieving PASI 75 and PASI 90 responses in both non-obese and obese individuals. Based on our study, among biological agents, IL-17 and IL-23 inhibitors may be more successful among obese individuals, but neither of them shows superiority over the other.

Effects of Anatolian Propolis and Hypertonic Saline Combination Nasal Spray on Allergic Rhinitis Symptoms: A Prospective, Multicenter Study.

Objectives: This study aimed to evaluate how Rhinapi nasal spray affects symptoms of allergic rhinitis. Methods: In this prospective, multicenter, observational study, 10,000 patients (comprising 5028 males and 4972 females) exhibiting symptoms of allergic rhinitis (namely, nasal discharge, sneezing, nasal itching, and nasal obstruction) from different centers in different regions of Turkey were enrolled in the study between March 2022 and March 2023. All the patients wanted to participate in the study and were administered Rhinapi one puff to each nostril three times a day, for a period of 3 weeks. Total symptom scores, quality of life (QoL) scores, and otolaryngological examination scores were evaluated before and 3 weeks after treatment. Results: The scores for discharge from the nose, sneezing, nasal pruritus, and blockage of the nose all indicated improvement when compared to pre-medication and post-medication. This difference achieved statistical significance (P < .001). The mean total symptom score fell following treatment (P < .001): whilst the score was 11.09 ± 3.41 before administering Rhinapi; after administration, the average score was 6.23 ± 2.41. The mean QoL scores also altered after medication (P < .001), improving from a mean value of 6.44 ± 1.55 to a mean of 7.31 ± 1.24. Significant improvement was also noted in the scores for conchal color and degree of edema after the treatment had been administered (P < .001). Conclusion: The study demonstrates that Rhinapi nasal spray decreases total symptom scores, and results in improved QoL and otolaryngological examination scores. Propolis spray may be recommended for patients with allergic rhinitis alongside other treatments.

Suicide commitment with metformin: our experience with five cases.

Biguanides can function as oral antihyperglycemic drugs. They were used for diabetes mellitus or prediabetes treatment over the last nine decades, but they lost their popularity in 1970s because of phenformin and regained with metformin. For metformin, the most common side effects are diarrhea and dyspepsia, occurring in up to 30% of patients. The most important and serious side effect is lactic acidosis. Phenformin was removed from the markets before 1970, because it caused lactic acidosis in 40-65 patients in 100,000 patient-years. Metformin causes lactate accumulation only in patients who have hepatic failure, renal failure or in patients who attempt suicide with high dosage of drugs. In this report, we present five patients who used high doses of metformin for suicide attempt.

Are the hearing and eustachian tube functions of the hot air balloon pilots disturbed?

OBJECTIVE: To evaluate the hearing and Eustachian tube functions (ETF) of hot air balloon (HAB) pilots, who are exposed to high altitude occupationally. MATERIALS AND METHODS: The study was designed as a cross-sectional controlled study. Thirty HAB pilots and 30 healthy volunteers were included. Pure tone audiometry and speech discrimination scores (SDS) were used to assess the hearing function. Pure tone average (PTA) was calculated using the hearing thresholds (HT) at the frequencies 500, 1000, 2000, and 4000 Hz. Tympanometry and automatic Williams test (ETF1) were conducted to assess the ETF of the participants. Eustachian Tube Dysfunction (ETD) was defined as the change of tympanometric peak pressure (TPP) at rest (P1) less than in 10 decapascals (daPa) with Valsalva (P2) and Toynbee (P3) maneuvers. Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) was also administrated. RESULTS: Mean ages of the participants were 32.03±8.12 and 32.33±9.47 years in the HAB and control groups, respectively (p = 0.865). HTs, PTAs, SDSs, P1, P2, P2-P1 and P1-P3 values were similar in the groups (p > 0.05). P3 values ​​in both ears were significantly higher in the HAB group compared to the control group (p = 0.018, p = 0.002). Positive correlations were detected between the duration of the experience of HAB pilots and their HTs at 4 kHz and 8 kHz (p < 0.05) The prevalence of ETD in at least one ear was 83.7% and in both ears was 43.3% in the HAB group, both of which were significantly higher than the control group (p = 0.001, p = 0.049). The ETDQ-7 scores were also higher in the HAB group compared to the control group (p < 0.001). CONCLUSION: Both the subjective and objective measures of ETF indicate that ETD is common among the HAB pilots. However, the hearing functions of those seem to be unaffected.

Increased Serum Lipid Levels in Patients with Subjective Tinnitus.

INTRODUCTION: The aim was to investigate the link between tinnitus and serum levels of total cholesterol (TC), triglyceride (TRG), low-density (LDL) and high-density lipoprotein (HDL) in the central anatolian Turkish population. MATERIALS AND METHODS: The retrospective and case-control study included a total of 91 patients with subjective tinnitus and a control group of age- and sex-matched 65 healthy volunteers. A detailed otolaryngologic examination followed by pure tone audiometry, serum lipid values, and magnetic resonance imaging of the temporal bone was performed. The clinical characteristics of tinnitus were registered for all patients. The serum levels of TC, TRG, LDL and HDL were compared between the two groups. RESULTS: Mean TC level was 200.57±41.06 mg/dL in the patient group and 179.0±39.03 mg/dL in the control group (P=0.001). Mean TRG level was 177.76±86.94 mg/dL in the patient group and 124.43±61.44 mg/dL in the control group (P=0.000). Mean LDL level was 115.88±32.56 mg/dL in the patient group and 101.31±34.42 mg/dL in the control group (P=0.008). Mean HDL level was 50.25±13.60 mg/dL in the patient group and 53.46±12.66 mg/dL in the control group (P=0.137). Among all the serum lipids, TC, TRG and LDL established a significant difference between the two groups. CONCLUSION: The results indicated that TC, TRG and LDL levels were significantly higher in tinnitus group and this increase implicates the potential role of hyperlipidemia associated with altered lipid metabolism in the etiology of tinnitus. We suggest that serum lipid levels could be useful and conducive in the diagnosis and prognosis of tinnitus.

The systolic pulmonary artery pressure and the E/e' ratio decrease after septoplasty in patients with grade 2 and 3 pure nasal septal deviation.

INTRODUCTION: Nasal septal deviation may contribute to a wide range of symptoms including nasal obstruction, headache, increased secretion, crusting, mucosal damage, and loss of taste and smell. Excessive increase in the respiratory resistance, as seen in nasal septal deviation, results in reduced lung ventilation, thereby potentially leading to hypoxia, hypercapnia, pulmonary vasoconstriction. The deformities in the nasal cavity can be associated with major respiratory and circulatory system diseases. OBJECTIVE: To investigate cardiovascular effects of septoplasty by comparing pre- and postoperative transthoracic echocardiography findings in nasal septal deviation patients undergoing septoplasty. METHODS: The prospective study included 35 patients with moderate and severe nasal septal deviation (mean age, 23.91±7.01) who underwent septoplasty. The Turkish version of the nasal obstruction symptom evaluation, NOSE questionnaire, was administered to each participant both pre- and postoperatively in order to assess their views on the severity of nasal septal deviation, the effect of nasal obstruction, and the effectiveness of surgical outcomes. A comprehensive transthoracic echocardiography examination was performed both preoperatively and at three months postoperatively for each patient and the findings were compared among patients. RESULTS: Mean preoperative NOSE score was 17.34±1.62 and the mean postoperative score was 2.62±1.68 (p=0.00). Mean preoperative systolic pulmonary artery pressure value was 22.34±4.31mmHg and postoperative value was 18.90±3.77mmHg (p=0.00). Mean E/e' ratio was 5.33±1.00 preoperatively and was 5.01±0.90 postoperatively (p=0.01). The NOSE scores, systolic pulmonary artery pressure values, and the E/e' ratios decreased significantly after septoplasty (p<0.05 for all), whereas no significant difference was found in other transthoracic echocardiography parameters (p>0.05). CONCLUSION: The decrease in NOSE scores following septoplasty indicated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to nasal septal deviation may be a cardiovascular risk factor and may affect transthoracic echocardiography measurements. Moreover, the significant decrease in the systolic pulmonary artery pressure value and E/e's ratio following septoplasty indicated that negative echocardiographic findings may be prevented by this surgery.

Protective effect of N-acetylcysteine against cisplatin ototoxicity in rats: a study with hearing tests and scanning electron microscopy.

INTRODUCTION: Ototoxicity is a health problem appearing after powerful treatments in serious health conditions. It is sometimes inevitable when treatment of the serious disease is required. Cisplatin is an antineoplastic agent which was investigated previously to reveal increased nitrogen and reactive oxygen radicals that damages hair cells, resulting in ototoxicity. N-acetylcysteine, previously shown to decrease ototoxicity caused by different agents, is known to be a powerful in vitro antioxidant. Probably N-acetylcysteine, in addition to its antioxidant effect, blocks a cascade where reactive oxygen species result in apoptosis in the cochlea. OBJECTIVES: The possible preventive effect of N-acetylcysteine in cisplatin ototoxicity was studied with auditory brain stem responses, otoacoustic emissions, and histopathological investigation of the cochlea in a scanning electron microscopy. METHODS: This study was conducted on 21 Wistar Albino rats in four groups. 1mL/kg/day three times in total intraperitoneal (i.p.) Saline (n=5), 500mg/kg/day i.p. three times in total N-acetylcysteine (n=5), i.p. 15mg/kg cisplatin alone (single dose) (n=5) and i.p. 15mg/kg cisplatin plus 500mg/kg/day N-acetylcysteine (n=6) were administered. The rats were anesthetized to study the hearing tests before and after the experiment. The rats were sacrificed to investigate the cochleas by scanning electron microscopy. RESULTS: Auditory brain stem responses and otoacoustic emissions values were attenuated in the cisplatin group. The group that received N-acetylcysteine in addition to cisplatin had better auditory brain stem responses thresholds and otoacoustic emissions. The samples obtained from the cisplatin group showed surface irregularities, degeneration areas, and total or partial severe stereocilia losses. The changes were milder in the cisplatin+N-acetylcysteine group. CONCLUSION: Cisplatin ototoxicity can be detected by auditory brain stem responses and otoacoustic emissions testing in rats. N-acetylcysteine may protect the cochlear cells from histopathological changes. We concluded that N-acetylcysteine given 4h after cisplatin injection has a potential otoprotective effect against cisplatin ototoxicity. which suggests it could be used in clinical trials.

Acute Rhinosinusitis as an Infrequent Cause of Symptomatic Cluster Headache: Report of Seven Cases.

Cluster headache (CH) is a primary headache disorder characterized by unilateral headache attacks lasting 15 to 180 minutes, occurring between two and eight times a day, and accompanied by autonomic symptoms ipsilateral to the pain. However, cases of symptomatic CH that occur secondary to an underlying structural pathology have also been reported in the literature. In this report, seven patients are presented who were admitted with signs of CH and diagnosed with acute rhinosinusitis depending on extensive clinical and radiologic examinations. Symptomatic CH, though rarely reported in the literature compared to CH, should be kept in mind in patients presenting with the first attack of CH. Moreover, in such patients, whether the pain becomes worse when bending forward and becomes sensitive on palpation should be questioned, and a radiologic work-up should be performed to rule out secondary causes such as rhinosinusitis. In the present cases, the resolution of CH attacks with acute sinusitis therapy confirmed the diagnosis.

Can we use the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mean platelet volume values for the diagnosis of anterior uveitis in patients with Behcet's disease?

INTRODUCTION: The purpose of this study was to compare the value of hematological parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV), as indicators of anterior uveal segment involvement in patients with Behcet's disease (BD). PATIENTS AND METHODS: Hospital-based records of a total of 912 patients with BD from the dermatology clinic and healthy volunteers from the checkup clinic were assessed retrospectively. After applying the exclusion criteria of the study, 71 of the BD patients with anterior uveitis, 69 of the BD patients without ophthalmological pathology and 151 healthy volunteers were included in the study. MPV, PLR, and NLR values of patients and healthy volunteers were compared. RESULTS: All MPV, PLR, and NLR values of patients who had anterior uveitis were significantly higher than those of other patients and healthy volunteers. Statistically, considering area under curves (ratio): NLR was 0.725 (0.653-0.797), P<0.001; PLR was 0.600 (0.523-0.676), P=0.012, and MPV was 0.358 (0.279-0.437), P<0.001. CONCLUSION: MPV, PLR, and NLR are all valuable for assessment of anterior uveal segment involvement in patients with BD. However, the NLR seems to be better than the PLR and MPV for indicating anterior uveitis due to BD.

The association of serum gamma-glutamyl transpeptidase level and other laboratory parameters with blood pressure in hypertensive patients under ambulatory blood pressure monitoring.

BACKGROUND: Hypertension is a very important cause of morbidity and mortality. Serum gamma-glutamyl transpeptidase (GGT) is a biomarker of oxidative stress and associated with increased risk of hypertension and diabetes. The aim of this study was to evaluate the association of serum GGT level, which is an early marker of inflammation and endothelial dysfunction, with the deterioration of the diurnal rhythm of the blood pressure. METHODS: A total of 171 patients with hypertension were included in this study. Patients whose nighttime mean blood pressure, measured via ambulatory blood pressure monitoring, decreased between 10% and 20% compared with the daytime mean blood pressure were defined as "dippers", whereas patients with a nighttime blood pressure decrease lower than 10% were defined as "non-dippers". RESULTS: A total of 99 hypertensive patients (65 females/34 males) were classified as dippers and 72 patients (48 females/24 males) as non-dippers. The mean age of the non-dipper group was significantly greater than the dipper group. Serum GGT, C-reactive protein and uric acid levels were significantly higher among patients in the non-dipper group. Negative correlations were detected between GGT levels and diurnal systolic and diastolic blood pressure decreases. CONCLUSION: Our findings revealed that GGT level was higher in the non-dipper group, and was negatively correlated with the nighttime decrease of diurnal blood pressure. C-reactive protein and uric acid levels were also higher in the non-dipper group. However, future randomized controlled prospective studies with larger patient populations are necessary to confirm our findings.

Acute Pancreatitis Caused By Mushroom Poisoning: A Report of Two Cases.

Of the more than 5000 species of mushrooms known, 100 types are toxic and approximately 10% of these toxic types can cause fatal toxicity. A type of mushroom called Amanita phalloides is responsible for 95% of toxic mushroom poisonings. In this article, we report 2 cases of mushroom poisonings caused by Lactarius volemus, known as Tirmit by the local people. The patient and his wife were admitted to the emergency room with abdominal pain, nausea, and vomiting 20 hours after consuming Lactarius volemus, an edible type of mushroom. The patients reported that they had been collecting this mushroom from the mountains and eating them for several years but had never developed any clinicopathology to date. Further examination of the patients revealed a very rare case of acute pancreatitis due to mushroom intoxication. The male patient was admitted to the intensive care unit while his wife was followed in the internal medicine service, because of her relative mild clinical symptoms. Both patients recovered without sequelae and were discharged. In this article, we aimed to emphasize that gastrointestinal symptoms are often observed in mushroom intoxications and can be confused with acute pancreatitis, thus leading to misdiagnosis of patients. Early diagnosis and appropriate treatment can improve patients' prognosis and prevent the development of complications.

Effect of Septoplasty on Voice Quality: A Prospective-Controlled Trial.

OBJECTIVES: The purpose is to investigate effect of septoplasty and widened nasal patency on voice quality. METHODS: Fifty patients who undergone septoplasty were included in the study. Thirty-three people who had similar age and distribution were enrolled as control group. Before and 1 and 3 months after surgery, anterior rhinomanometry, voice analysis by Multi-Dimensional Voice Program, and spectrographic analysis were performed to patients. The recordings of /a/ vowel were used to evaluate average fundamental frequency (F0), jitter percent, and shimmer percent. In spectrographic analyses, F3-F4 values for the vowels /i, e, a, o, and u/, nasal formant frequencies of the consonants /m/ and /n/ in the word /mini/, and 4 formant frequencies (F1, F2, F3, and F4) for nasalized /i/ vowel following a nasal consonant /n/ in the word /mini/ were compared. The differences in nasal resonance were evaluated. All patients were asked whether change in their voices after the surgery. Preoperative and postoperative voice parameters and anterior rhinomanometry results were compared separately with the control group as well as in the patient group itself. RESULTS: Preoperative total nasal resistance (TNR) values of patients were higher than the control group (P=0.001). TNR values of patients measured one day before surgery and after surgery in the 1st and 3rd months were different and these differences were significant statistically (P=0.001). There was no significant difference between the voice analysis parameters in preoperative, postoperative 1st, and 3rd months. As a result of their subjective reviews, 12 patients (36%) noted their voices were better than before surgery and 20 patients (61%) noted no change before and after surgery. CONCLUSION: Providing widened nasal cavity has no effect on voice quality.

Evaluation of the effect of intranasal infiltrated botulinum toxin-A on a model of allergic rhinitis in rabbits: An Experimental Study.

INTRODUCTION: Allergic Rhinitis (AR) effects 20-40% of the global population and its prevalance increases. Medical treatment and immunotherapy could be used in AR management. But they are not definitive solution. Medical treatment must be used a long time and has side effects. Immunotherapy cannot be applied to every patient and it also takes a long time. The aim of this study is to evaluate symptomatic and histopathological effects of intranasal infiltrated Botulinum Toxin-A (Btx-A) on an animal model of AR. MATERIAL-METHOD: 15 rabbits were divided into 3 groups as control, disease and treatment. AR was formed in disease and treatment groups by intraperitoneal and intranasal ovalbumine. Allergic symptoms were observed and serum IgE levels were estimated to prove forming of AR. Btx-A was infiltrated in inferior turbinates of rabbits in treatment group. Rabbits were sacrified on 32nd day. Paranasal structures were disected and investigated histopathologically. RESULTS: Serous nasal discharge and sneezing were observed after ovalbumine applying in disease and treatment groups. Serum IgE levels on 21st day were higher than 1st day and this difference was significant statistically in disease and treatment groups. Serous discharge and sneezing decreased after Btx-A infiltration in treatment group. In histopathological examination, there were significant difference between disease and treatment group in terms of some histopathological findings. CONCLUSION: Considering the effect of Btx-A on AR in animal, it can be said that Btx-A can decrease symptoms and reorganize histopathological findings of AR.

Nutritional Risk, Micronutrient Status and Clinical Outcomes: A Prospective Observational Study in an Infectious Disease Clinic.

Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002) and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient's admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40), 46.6% (n = 29), 39.7% (n = 27), 35.3% (n = 24), 14.1% (n = 9), respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

Cytogenetic damage of radiotherapy in long-term head and neck cancer survivors.

PURPOSE: To evaluate cytogenetic damage of radiotherapy (RT) and chemoradiotherapy (CRT) in long-term head and neck cancer survivors. MATERIALS AND METHODS: This study included 20 patients treated with RT (10 patients) or CRT (10 patients) for head and neck cancer. Nine healthy volunteers were included as control subjects. Cytochalasin B-blocked micronucleus (CBMN) assay was used to evaluate cytogenetic damage. To evaluate micronucleus (MN) by CBMN, the venous blood samples were drawn median 68 months (range 60-239 months) after the completion of treatment (RT or CRT) for head and neck cancer. RESULTS: Nuclear division index (NDI) and number of MN in mononuclear and binuclear lymphocytes were significantly higher in patients with head and neck cancer than in control subjects [1.19 (1.08-1.47) vs. 1.07 (1.04-1.14), p < 0.001; 11.0 (2.0-22.0) vs. 1.0 (0-3.0), p < 0.001 and 15.0 (5.0-45.0) vs. 9.0 (2.0-15.0), p = 0.020, respectively]. NDI and number of MN in mononuclear lymphocytes were significantly lower in control subjects compared patients received CRT and those received only RT, but there was no significant difference between patients received CRT and those received only RT. Number of MN in binuclear lymphocytes was significantly lower in control subjects compared to patients received CRT, but there was no significant difference between control subjects and those received only RT. Also there was no significant difference between patients received CRT and those received only RT in terms of number of MN in binuclear lymphocytes. CONCLUSIONS: MN frequency of mononuclear and binuclear lymphocytes in medical follow-up of patients with head and neck cancer after RT could be important in evaluating cytogenetic damage of RT. However, further investigations are needed to provide quantitative correlations between MN yields and the clinical features in post-radiotherapy period.

Are the blood groups of women with preeclampsia a risk factor for the development of hypertension postpartum?

INTRODUCTION: Preeclampsia (PE) is a pregnancy-related disorder characterized by hypertension (HT) and proteinuria noticeable after 20 weeks of gestation. PE is now considered as a cardiovascular disease risk factor and a number of studies have shown that experiencing PE increases the prevalence of various cardiovascular risk factors, such as metabolic syndrome and HT. In this study, we aimed to investigate any possible relationship between the ABO/Rh blood group system and PE in Turkey. In the second part of the study, we examined the relationship between the ABO blood group system and development of HT after PE. PATIENTS AND METHODS: A total of 250 patients with PE from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. Patients were classified according to blood groups (A, B, AB, and O) and Rh status (+/-). RESULTS: There was a significant difference between the patients with PE and the control group in terms of distribution of ABO blood groups and the percentage of group AB was found to be higher in patients with PE compared to the control group (P=0.029). The risk of developing PE was significantly higher in group AB than other blood groups (P=0.006). The risk of developing HT after PE was significantly higher in group O than other blood groups (P=0.004). DISCUSSION: In this study, we found that the patients with blood group AB have a higher risk for PE. The patients with PE of blood group O are at high risk of developing HT, and Rh factor was identified as another risk at this point and these patients should be closely followed postpartum.

A Prospective Experimental Study on the Protective Effect of Resveratrol against Amikacin-Induced Ototoxicity in Rats.

OBJECTIVE: The purpose of this study was to evaluate the protective effect of resveratrol against amikacin-induced ototoxicity in rats by otoacoustic emission and histopathology of the cochlea. MATERIALS AND METHODS: This study was conducted with 31 Sprague Dawley adult female rats that were 20-21 weeks old and 190-245 g in weight. Before the drug administration, distortion product otoacoustic emission (DPOAE) tests were performed in both ears of each rat. The rats were divided into four groups. Group 1 (n=7) received ethanol 1cc 4%, Group 2 (n=8) received 600 mg/kg amikacin, Group 3 (n=8) received 10 mg/kg resveratrol and 600 mg/kg amikacin, and Group 4 (n=8) received 1cc resveratrol at 10 mg/kg. The drugs were administered once a day for 21 consecutive days. Control DPOAE tests were performed at the 7th, 14th, and 21st days after the administration of drugs. At the end of the study, the rats were sacrificed and their cochleae were dissected. The cochleae were evaluated for histopathologic changes. RESULTS: There was no statistically significant difference in the DPOAE measurements before the procedure between groups. The DPOAE measurements significantly decreased after the procedure in the amikacin group. There was no statistically significant difference in DPOAE measurements after the procedure in the amikacin + resveratrol, resveratrol, and ethanol groups. The histopathologic findings supported these results. CONCLUSION: We found that if resveratrol is administered with amikacin, the severity of amikacin-induced hearing loss is decreased. These findings suggest that resveratrol, a strong antioxidant, has a protective effect in amikacin ototoxicity.
