Comparison of preoperative anxiety, bruxism, and postoperative pain among patients undergoing surgery for septoplasty, endoscopic sinus surgery, and tympanoplasty.

Background: Septoplasty, endoscopic sinus surgery, and tympanoplasty are the most commonly performed elective functional ear-nose-throat surgeries. Aim: This study investigated the relationship between preoperative anxiety, bruxism, and postoperative pain in inpatient groups undergoing three different functional otorhinolaryngologic surgeries. Patients and. Methods: This study was conducted in a single center of a tertiary referral hospital. The patients (n = 90) who had undergone septoplasty (group A), endoscopic sinus surgery (group B), and tympanoplasty (group C) were included. The State-Trait Anxiety Inventory (STAI) questionnaire and the Amsterdam Preoperative Anxiety Information Scale (APAIS) were administered. To evaluate bruxism, a self-questionnaire was administered, and for the evaluation of pain, the visual analogue scale (VAS) was administered. Results: In group C, preoperative STAI and APAIS and early and late pain values were higher than in the other groups. When patients were divided into two groups according to the presence of bruxism. A significant difference was found between the preoperative STAI and immediate and late VAS values (P < 0.001). A strong correlation was observed between APAIS and early and late VAS values in group C (P < 0.001). Conclusion: Patients who will undergo tympanoplasty should be aware of the preoperative anxiety level and pain follow-up. Bruxism can be considered a vital follow-up parameter that manifests due to high preoperative anxiety. It may also be useful to examine preoperative bruxism and take appropriate measures due to its pain-increasing effect in patients.

The clinicopathological features and survival of Castleman disease: a multicenter Turkish study.

OBJECTIVE: In this study, we aimed to investigate the clinicopathological features and survival of CD, which is quite rare and has many unknowns. PATIENTS AND METHODS: This study was conducted by retrospectively evaluating patients diagnosed with CD in six different centers in Turkey. RESULTS: The median age of 33 patients included in the study was 49 and 51.5% (n = 17) of these patients were women. 18 (54.5%) patients were in the hyaline vascular subtype and most of the patients were UCD (n = 20, 60.6%). The most common involvement region was head and neck (n = 19, 57.5%). The UCD group was younger than the MCD group (p=0.027). Visceral lymph node involvement was higher in MCD than in UCD (p=0.001). Similarly, it was observed that there was more hepatomegaly (p=0.035) and splenomegaly (p=0.013) in the MCD group. During the median 19.5 months follow-up period, there were no patients who died. CONCLUSIONS: It was observed that UCD and MCD are different clinical entities. Promising survival times can be achieved with surgical and systemic treatments in both subtypes of this extremely rare disease. However, this result should be supported by well-designed prospective comprehensive studies.

Nasal eosinophilia in nasal smears of patients with persistent and intermittent allergic rhinitis.

BACKGROUND: Eosinophils are the principal effector cells involved in the pathogenesis of allergic rhinitis. Cell numbers increase in non-allergic rhinitis patients with eosinophilia, aspirin hypersensitivity and nasal polyposis, as well as in allergic rhinitis patients. Exfoliative nasal cytology can be used in the differential diagnosis of allergic rhinitis. OBJECTIVE: To evaluate nasal eosinophilia in nasal smears of patients with mild, persistent and intermittent allergic rhinitis. METHODS: The study comprised 60 patients with allergic rhinitis and 20 healthy volunteers. The patients were divided into intermittent and persistent allergic rhinitis groups. Nasal smear status, eosinophil numbers and Total Nasal Symptom Scores were compared. RESULTS: Nasal smear results were pathological in 40 of 60 allergic rhinitis patients, which was significantly higher than the rate in controls. The mean nasal eosinophilia score was significantly higher in the intermittent allergic rhinitis than in the persistent allergic rhinitis group (p = 0.029). There was a positive correlation between nasal eosinophilia score and Total Nasal Symptom Score (r = 0.652; p < 0.05) in persistent allergic rhinitis and intermittent allergic rhinitis patients. CONCLUSION: The nasal smear test is inexpensive, objective and simple to perform, and should be part of the diagnostic investigation.

Cutaneous drug reactions to antiepileptic drugs and relation with HLA alleles in the Turkish population.

Summary: Background and objective. Many studies have shown associations between HLAB*15:02, HLA-A*31:01 and carbamazepine (CBZ)-induced delayed cutaneous hypersensitivity reactions. The aim of this study is to evaluate a possible association between delayed cutaneous reactions to antiepileptic drugs (AEDs) and certain HLA-A and HLA-B alleles in the Turkish population. Methods. The study consisted of 3 groups: Group I (reactive group) included the patients who had documented delayed cutaneous reactions to any antiepileptic drug. Group II (non-reactive group) included the patients who have been on antiepileptic treatment at least for three months without any adverse reactions. Group III consisted of healthy subjects. The HLA-A and B alleles were analyzed in all groups. Results. Forty patients (29 female) had experienced different hypersensitivity reactions due to AEDs: maculopapular exanthema (26 patients), Stevens-Johnson syndrome (6 patients), drug rash with eosinophilia and systemic symptoms (7 patients), toxic epidermal necrolysis (1 patient). Lamotrigine (11) and CBZ (10) were the most common culprit drugs involved in the reactions. The HLA-B*15:02 was not present in any of the study groups. However, HLA-B*35:02 was found in 4 patients from the reactive group, while it was not observed in non-reactive patients and was detected in only one healthy subject (p = 0.021). Conclusion. Although our preliminary results did not indicate a strong allele association with AED hypersensitivity, HLA-B*35:02 appears to be a candidate allele for MPE / DRESS / DIHSS induced by AED's in Turkish population. Further studies with a larger sample size may result in more comprehensive data about the genetic tendency for AED hypersensitivity in the Turkish population.

Assessment of serum endothelin-1 levels in rat appendicitis model and the effects of bosentan.

OBJECTIVE: In this study, the diagnostic value of serum endothelin-1 (ET-1) levels and the therapeutic effects of bosentan have been investigated in an experimental appendicitis rat model. MATERIALS AND METHODS: Twenty-one male Sprague-Dawley rats were chosen for the study. The rats were allocated into three groups as follows: Group 1 (control, n = 7), Group 2 (appendicitis, n = 7), and Group 3 (bosentan treatment, n = 7). At the 6th hour of the experiment, Groups 1 and 2 received 2 ml saline, and group 3 received 30 mg/kg bosentan intraperitoneally. At the 24th postoperative hour, all rats were sacrificed and evaluated histopathologically to score the severity of appendicitis. The plasma malondialdehyde, reduced and total glutathione levels, serum, and appendiceal tissue ET-1 levels were evaluated. RESULTS: In this study, we found that the ET-1 levels were significantly increased with appendicitis (p = 0.018). The administration of bosentan can statistically significantly both decrease the histopathologic injury in the inflamed appendix and increase the serum total glutathione levels (p = 0.002). CONCLUSIONS: The increase in plasma ET-1 levels may have a diagnostic value of acute appendicitis. We believe that manifestations that occur during the acute phase of appendicitis may be reduced with the administration of bosentan, which may also help prevent complications.

Pedicled Vascularized Lymph Node Transfer Treats Lymphedema in Rat Hind Limb: A Simple Experimental Study Design.

Vascularized lymph node transfer is a new and promising technique for the physiologic treatment of lymphedema and several clinical and experimental studies have been conducted in recent years. However, the exact mechanism of vascularized lymph node transfer is still unknown. In this study, we aimed to investigate treatment efficacy through the design of a simple and feasible experimental lymphedema model for testing a vascularized lymph node transfer technique. After a pilot study, 30 male Sprague-Dawley rats were divided into two groups and lymphedema was induced in the hindlimb of both groups. In Group 1 (control, n=15) no treatment was applied while pedicled lymph node transfer was applied in Group 2 (experimental, n=15). Model dynamics were assessed with lymphoscintigraphy, limb measurement, and histological analysis. A statistically significant limb circumference reduction at the ankle was seen on days 30 and 90 in Group 2 as compared to Group 1, p<0.05, and lymphatic tracer transport improved in 13 out of the 15 animals in Group 2. A statistically significant reduction in histological scores was achieved in Group 2, p<0.05. In this rat hindlimb lymphedema model, our vascularized lymph node transfer technique is an effective physiologic surgical treatment and represents a feasible experimental model for future studies.

How do voice restoration methods affect the psychological status of patients after total laryngectomy?

OBJECTIVE: This study investigated the relationship between psychological well-being and different voice rehabilitation methods in total laryngectomy patients. METHODS: The study enrolled 96 patients who underwent total laryngectomy. The patients were divided into three groups according to the voice rehabilitation method used: esophageal speech (24 patients); a tracheoesophageal fistula and Provox 2 voice prosthesis (57 patients); or an electrolarynx (15 patients). The participants were asked to complete the Turkish version of the Voice Handicap Index-10 (VHI-10) to assess voice problems. They were also asked to complete the Turkish version of the Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). The test scores of the three groups were compared statistically. RESULTS: Patients who used esophageal speech had a mean VHI-10 score of 10.25 ± 3.22 versus 19.42 ± 5.56 and 17.60 ± 1.92 for the tracheoesophageal fistula and Provox 2 and electrolarynx groups respectively, reflecting better perception of their voice. They also had a PSS score of 11.38 ± 3.92, indicating that they felt less stressed in comparison with the tracheoesophageal fistula and Provox 2 and electrolarynx groups, which scored 18.84 ± 5.50 and 16.20 ± 3.49 respectively. The HADS scores of the groups were not different, indicating that the patients' anxiety and depression status did not vary. CONCLUSION: Patients who used esophageal speech perceived less stress and were less handicapped by their voice.

Giant fibrolipoma with osseous metaplasia on the thigh.

Fibrolipomas are characterised by fat lobules embedded in perivascular oval fibrocytes and thick bundles of collagen. Actively growing superficial fibrolipomas rarely display a pedunculated protrusion and, thus, cosmetic and functional problems are uncommon. We present an exceptional case. While trauma and ischaemia can lead to fibrosis and dystrophic calcification in fibrolipomas as late sequelae, osseous and cartilaginous metaplasia can infrequently manifest after a long, chronic persistence. Further, depending on the chronic irritation, ulcerated wounds may develop on the surface, and these can be clinically confused with malignancy. In this article, we present a case of a pedunculated giant fibrolipoma manifesting metaplasic changes in its structure.

Cost of paid transplantation abroad: possible donor-origin early multiple myeloma in a renal transplant recipient treated using bortezomib.

The incidence of cancer is greater in transplant recipients compared with the general population. Posttransplantation lymphoproliferative disorder (PTLD) is the second most common cancer in these patients. Non-Hodgkin lymphoma is most commonly observed, and multiple myeloma (PTLD-MM) accounts for less than 4% of PTLDs. Most reported PTLD-MM is of recipient origin, and to date, few cases of donor-origin PTLD-MM have been reported. Bortezomib is a protease inhibitor that has been used successfully to treat multiple myeloma. Herein, we describe the case of a patient in whom multiple myeloma developed shortly after paid living-unrelated renal transplantation performed abroad (in Egypt). The patient had no apparent risk factors for PTLD-MM. Thus, it was supposed that PTLD-MM was of donor origin, considering its early development, lack of recipient risk factors, and no available donor medical status. To our knowledge, this report is the first to describe the use of bortezomib in this setting. Although bortezomib plus dexamethasone therapy resulted in hematologic remission, the patient remained dialysis-dependent.

Facial motor cortex plasticity in patients with unilateral peripheral facial paralysis.

Hand motor representation area expands towards the area of the perioral facial motor cortex in patients with peripheral facial paralysis (PFP) and in hemifacial spasm cases treated with botulinum toxin. In this current study, we aimed to investigate the changes both in the ipsilateral and contralateral facial motor cortex areas in patients with PFP with transcranial magnetic stimulation (TMS). Thirty healthy individuals and 41 patients with unilateral PFP with partial or total axonal degeneration participated in this study. Motor evoked potentials (MEPs) of perioral muscles elicited by TMS of the intracranial portion of the facial nerve and motor cortex, were recorded. TMS was delivered through a figure-of-eight coil. Mapping of the cortical representation of perioral muscles were also studied in 13 of 41 patients and in 10 of control subjects. Mean amplitude of the intact perioral MEPs elicited by the ipsilateral hemisphere TMS, was significantly higher in patients than the control subjects. There was also a mild enlargement of the mean cortical representation area of intact perioral muscles on both hemispheres though it was not significant. We have concluded that there was a cortical reorganization in the hemisphere contralateral to the paralytic side resulting in an increase at corticofugal output related to intact perioral muscles.

Effects of different parent material on the mineral characteristics of soils in the arid region of Turkey.

Physical, chemical and mineralogical characteristics of seven soils developed on four different parent materials such as basalt, limestone, marine and alluvium were studied to determine the effect of parent material on the soil characteristics in the arid and semiarid regions in the Southeast Anatolia Region of Turkey. Parent material have affected the morphology and chemistry of the soils. Carbonate contents of the soils are changing between 14.1 and 42.6%. The high carbonate contents of the soils, developed on the basalt rocks, might be attributed to eolian additions from calcareous soils. The red colour of basaltic soils might be associated with the Fe2O3 content of the parent material. Available Fe2O3 content of the basaltic soils was relatively higher than other soils and measured between 0.56 and 2.05%. Available Fe2O3 content of the soils on the marine was very low and changed between 0.26 and 0.37%. Total Fe2O3 content of the basaltic soils was higher than other soils and changed between 4.36 and 6.70%. The total Al2O3 content of the basaltic soils was obtained relatively higher than other soils and changed between 4.92 and 8.72%. The high Al2O3 and Fe2O3 contents of the basaltic soils may be associated with the weathering of basalt rocks. Also analysis of the basaltic rock samples has showed similar mineralogical composition. X-Ray diffraction analysis data showed that smectite was the dominant clay mineral in all the soils. Palygorskite was the second most abundant mineral after smectite. Moreover, some mineralogical properties reflected the traces of climatic changed during the Holocene. The leaching factor were determined as >1 in the Profile PL2 and as < 1 in the Profiles PL1, PL3, PL4, PL5; PL6 and PL7. The low leaching factor (< 1) may be attributed to weathering of parent material. The soils were classified according to Soil Taxonomy as Aridisol, Entisol, Vertisol and Inceptisol.

Clinical experience with three combination regimens for the treatment of high-risk febrile neutropenia.

INTRODUCTION: The objective of this study was to compare the safety and efficacy of ceftazidime (2 g every 8 h), piperacillin/tazobactam (4 g/500 mg every 6 h), and meropenem (1 g every 8 h), when combined with amikacin (15 mg/kg once daily), in the empirical treatment of high-risk febrile neutropenic episodes in patients with haematological malignancy. MATERIALS AND METHODS: A prospective, comparative study designed in the haematology unit of a university hospital in Turkey. RESULTS: A total of 89 febrile episodes in 60 neutropenic patients were treated; 29 febrile episodes in 23 patients with ceftazidime plus amikacin (group 1), 30 episodes in 25 patients with piperacillin/tazobactam plus amikacin (group 2), and 30 episodes in 25 patients with meropenem plus amikacin (group 3). The 3 groups were comparable in terms of age, sex, underlying malignancy, pretherapy neutrophil counts, duration of neutropenia and types of infections. Neutropenia, since the start of fever, persisted for > or =10 days in all of the episodes in the 3 study groups. Nearly all of the episodes were seen in patients with acute leukaemia. In 25.8% (23/89) of the febrile neutropenia episodes, an aetiologic organism was isolated, with gram-negative bacteria being the most commonly isolated. The success without modification rates were 34.5%, 30% and 36.7% for groups 1, 2 and 3, respectively (P >0.05). After modification with a different class of antimicrobial therapy, the response rates increased to 65.5%, 63.3% and 70% for groups 1, 2 and 3, respectively (P >0.05). The mean duration of treatment and the time to defervescence were also comparable in all groups. In all arms, side effects were minimal. CONCLUSIONS: It is concluded that the 3 regimens were equally effective and safe in the empirical treatment of high-risk febrile neutropenic episodes.

Oxidant/antioxidant parameters and their relationship with chemotherapy in Hodgkin's lymphoma.

This study investigated changing levels of serum oxidant/antioxidant with chemotherapy and their relation to treatment in 34 Hodgkin's lymphoma patients. The patient population consisted of 19 males and 15 females. Mean age was 30.41 +/- 12.08 years. All patients received the adriamycin, bleomycin, vincristine and dexamethasone (ABVD) treatment protocol. Blood samples were taken before treatment, and on days 1 and 7 during treatment for measurement of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), malondialdehyde (MDA), nitric oxide (NO) and enzyme activities. After ABVD treatment, mean free radical levels were increased and antioxidant levels were significantly decreased in the serum. ABVD treatment results in an increase of free radical levels and a decrease of antioxidant levels in the serum of patients with Hodgkin's lymphoma.

Cutaneous metastasis of endometrial carcinoma with hemorrhagic nodules and papules.

BACKGROUND: Endometrium cancer is the fourth most frequent malignancy in women. However, skin metastasis from endometrium cancer is a very rare entity. CASE: A 58-year-old multiparous woman postmenopausal for ten years presented with multiple metastatic, nodular, hemorrhagic skin lesions located at the initial surgery and radiotherapy site 14 months after the original diagnosis was made. Combination chemotherapy was instituted, but the patient died after the second cycle of chemotherapy. CONCLUSION: Although endometrial cancer is one of the most frequent malignancies in women, skin metastasis from endometrial cancer is very rare. In reported cases metastasis from endometrial cancer has been most commonly noted at the initial surgery and radiotherapy site. Therefore, the initial surgical and radiotherapy site must be examined carefully for skin metastasis.

Central and peripheral motor conduction to cremasteric muscle.

The few electrophysiologic studies of the cremasteric muscle (CM) have mainly been restricted to the cremaster reflex with no reference to central and peripheral nerve conduction to the muscle, probably for technical reasons.Twenty-six normal adult male volunteers were studied by transcranial magnetic cortical stimulation (TMS) and stimulation of thoracolumbar roots. The genitofemoral nerve (GFN) was stimulated electrically at the anterior superior iliac spine and a needle electrode was inserted into the CM for conduction studies. The motor latency to the CM from the cortical TMS ranged from 20 to 33 ms among the subjects (25.8 +/- 2.9 ms, mean +/- SD). Magnetic stimulation of the lumbar roots produced a motor response of the CM within 9.6 +/- 1.9 ms (range, 6-15). The central motor conduction time to the CM was 16.5 +/- 2.8 ms (range, 10-21). Stimulation of the GFN produced a compound muscle action potential with a mean value of 6.4 +/- 1.8 (range, 4-10) ms in 23 of the 26 cases. Thus, central motor nerve fibers to the CM motor neurons exist, and there may be a representation area for the CM in the cerebral cortex. The GFN motor conduction time to the CM may have clinical utility, such as in the evaluation of the groin pain due to surgical procedures in the lower abdomen.

Changes in the perioral muscle responses to cortical TMS induced by decrease of sensory input and electrical stimulation to lower facial region.

OBJECTIVE: To determine the changes in the motor cortex due to repetitive electrical stimulation and cutaneous anesthesia in lower facial region. METHODS: A total of 11 subjects participated in the study of repetitive electrical stimulation, and 10 other subjects in the study of lower facial anesthesia. Facial nerve root and face associated cortical MEPs by transcranial magnetic stimulation (eight-shaped coil) were recorded from perioral muscles pre- and post- electrical stimulation and lower facial anesthesia. Cheek near to the corner of the mouth was transcutaneously stimulated by bipolar surface electrode giving repetitive electrical shocks at 5 Hz. Five percent lidocain/prilocain local anesthetic cream was applied to left or right lip-cheek region. RESULTS: There was no significant change in perioral MEP responses after 10-30 min of 5 Hz electrical stimulation. We found a significant increase of amplitude in cortical MEP recordings during lower facial anesthesia especially in cases of cortical magnetic stimulations ipsilateral and contralateral to the anaesthetized side and in perioral recordings contralateral to the anaesthetized side. CONCLUSIONS: The present study demonstrates that topical anesthesia to the lower facial region leads to cortical modulation and fast plastic changes in both hemispheres that are directed to the normal side.

Blastic natural killer cell leukaemia with skin involvement: a case report.

Natural killer cell leukaemia is generally accompanied by extramedullary involvement. CD4+ natural killer cell leukaemia frequently manifests with cutaneous involvement. The disease pursues a very aggressive course with no long-term survivors reported. We present a patient with CD4+ natural killer cell leukaemia with skin, bone marrow and peripheral blood involvement who is still on remission at the end of 2 years.

Bilateral hearing loss during vincristine therapy: a case report.

Vincristine sulfate is a chemotherapeutic agent used in different cancer therapies. It is also the first choice of treatment for peripheral T-cell lymphoma with cyclophosphamide and adriamycin. Sudden hearing loss during vincristine therapy is a very rare event. This is a case of a 16-year old girl who developed sudden bilateral hearing loss related to vincristine therapy.

Isolated thrombocytopenia: the presenting finding of typhoid fever.

Thrombocytopenia is generally seen as a complication in typhoid fever. However, it can also be encountered as a presenting sign on admission. A 29-year-old man with complaints of fever and diarrhoea was hospitalized because of isolated thrombocytopenia encountered on routine complete blood count examination. The diagnosis of typhoid fever was established when Salmonella typhi was isolated from the blood cultures. The platelet count returned to normal level within the first week of ceftriaxone therapy. Possible mechanisms of thrombocytopenia were discussed.
