Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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 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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To clarify the pathophysiology of dysphagia by electrophysiological methods. METHOD Electrophysiological methods related to oropharyngeal swallowing were used to investigate 25 patients with cervical dystonia and 25 age matched normal volunteers. RESULTS Dysphagia was suspected in 36% of patients with cervical dystonia on the basis of clinical assessment. The incidence of dysphagia increased to 72% on electrophysiological evaluation of pharyngeal swallowing. Submental muscle electromyographic (EMG) and laryngeal relocation times were significantly prolonged and the triggering time to swallowing reflex was significantly delayed. Some abnormalities seen in cricopharyngeal sphincter muscle EMG indicated that the striated sphincter muscle is hyperreflexive in some patients. CONCLUSION Neurogenic dysphagia was more prominent and longer lasting than mechanical dysphagia, which was transient and varied from patient to patient. Although these electrophysiological methods were not suitable for detecting anatomical changes during swallowing, as in videofluoroscopic studies, observations supported the neurogenic cause of dysphagia in patients with any kind of cervical dystonia.

Abstract
Gemcitabine is a nucleoside analogue that has shown to have antineoplastic activity in different solid tumours (lung, pancreas, bladder, colon, ovarian, and breast cancer) and malignant mesothelioma. The toxic effects of gemcitabine include myelosuppression, flu-like syndrome, altered liver function tests, bronchospasm, rash, itching, and fever. However, gemcitabine-induced erysipeloid skin reaction was reported in a small number of patients with previous history of radiotherapy or lymphedema. We reported a male patient who developed erysipeloid skin reaction following gemcitabine treatment in the absence of radiotherapy and lymphedema.

Abstract
The facial nerve contributes to the oropharyngeal phase of deglutition via the buccinator, perioral, digastricus posterior, and stylohyoid muscles. The gustatory and salivatory functions of the facial nerve are also known to contribute to swallowing. The relation between peripheral facial nerve palsy (PFP) and swallowing dysfunction has never been studied systematically. Forty four patients with unilateral Bell's palsy (acute or chronic stages) and 20 normal control subjects were investigated. In 66% of patients with PFP, oropharyngeal swallowing was disturbed as demonstrated electrophysiologically by the patients' dysphagia limit at or below 20 ml of water. In patients with PFP investigated within the first 2 weeks of the palsy, the dysphagia limit normalised during the period of recovery. Normalisation of the dysphagia limit is highly correlated with the recovery of PFP. Thus, subclinical deglutition is very frequent in patients with PFP. The severity of abnormal deglutition increased with the severity of the PFP, especially with the involvement of the perioral and buccinator muscles.

Abstract
BACKGROUND Ineffective erythropoiesis and intramedullary hemolysis are the two important results of pernicious anemia. Hemolysis is one of the risk factors in the formation of gallbladder stones. PATIENTS AND METHODS The frequency of gallstones was searched in 59 patients with pernicious anemia and in 54 healthy subjects. RESULTS Nineteen (32.2%) patients in the pernicious anemia group and three (5.5%) patients in the control group were detected to have gallstones. Pernicious anemia patients with and without gallbladder stones were also compared for mean corpuscular volume, hemoglobin, unconjugated bilirubin, lactic dehydrogenase, and vitamin B12 levels but no statistically significant difference was encountered. CONCLUSION Apart from other risk factors, pernicious anemia itself increases the frequency of gallbladder stones. Should patients with pernicious anemia develop upper-abdominal pain or other symptoms referable to biliary tract disease, a high index of suspicion for gallstone-related disease should be maintained.

Abstract
BACKGROUND AND PURPOSE We have investigated the pathophysiological mechanisms of dysphagia in Wallenberg's syndrome (WS) that are due to lateral medullary infarction (LMI). METHODS Twenty patients with WS were evaluated by means of clinical and electrophysiological methods that measured the oropharyngeal phase of voluntarily initiated swallowing. For comparison, 22 patients with unilateral hemispheric infarction were investigated during the acute stage of stroke, and 4 patients with unilateral peripheral 9th and 10th cranial nerve palsies were studied. Age-matched 30 healthy control subjects were also included in the study. RESULTS It was found that dysphagia was clinically more severe in WS patients than in the patients in the other groups. The pharyngeal phase of swallowing was predominantly impaired, whereas in patients with hemispheric stroke, dysphagia was related only to the delay of triggering of the voluntarily induced swallowing. In WS patients, the swallowing reflex was extremely slow in spite of the unilateral involvement due to LMI, whereas the pharyngeal phase of reflex swallowing remained within normal limits in patients with unilateral hemispheric stroke and patients with unilateral peripheral 9th and 10th cranial nerve palsies. CONCLUSIONS Although in WS the lesion due to LMI is unilateral, its effect on oropharyngeal swallowing is bilateral. In LMI, primarily the premotor neurons in the nucleus ambiguous and their connections seem to be affected. Consequently, a disruption and/or disconnection of their linkage to swallowing-related cranial motor neuron pools bilaterally and to the contralateral nucleus ambiguous could produce the swallowing disorders in WS. However, the remaining intact ipsilateral premotor neurons and the contralateral center in the medulla oblongata may eventually begin to operate and overcome the severity and long-term persistence of dysphagia.

Abstract
The electrophysiological features of voluntarily induced and reflexive/spontaneous swallows were investigated. In normal subjects, swallows were elicited by infusing water either into the mouth (1-3 ml) or directly into the oropharyngeal region through a nasopharyngeal cannula (0.3-1 ml). For water infused orally, subjects were either requested to swallow voluntarily or instructed to resist swallowing and maintain the horizontal head position until swallowing occurred reflexively. Spontaneous saliva swallowing was investigated in patients with severe dysphagia who had a prominent clinical picture of suprabulbar palsy. Comparisons between different swallowing types were made by measuring the time interval between the onset of submental electromyographic activity (SM-EMG) and the onset of the upward movement of the larynx recorded by a movement sensor. This interval was less than 100 ms, even frequently less than 50 ms, in reflexive/spontaneous swallows, while in voluntarily induced swallows it was substantially longer. The rising time of submental muscle's excitation was also shorter in reflexive/spontaneous swallows. It was suggested that the triggering of voluntarily induced swallows commences more than 100 ms before the onset of swallowing reflex and that this mechanism is under the control of corticobulbar-pyramidal pathways. If the swallowing reflex is triggered within such a short period of time following the onset of SM-EMG, the central control by the bulbar swallowing center should be effective until the end of oropharyngeal swallowing.

Abstract
OBJECTIVE Cricopharyngeal (CP) muscle of the upper oesophageal sphincter (UES) has a significant role in the pharyngo-esophageal phase of deglutition. The linkage between the CP muscle of UES and the motor cortex has not been previously studied electrophysiologically in healthy humans and in patients with neurogenic dysphagia. METHODS Needle recordings of EMG responses were carried out from the CP sphincter muscle following transcranial magnetic stimulation (TMS) over the vertex around the Cz electrode position (cortical MEP), and on the parieto-occipital skull and the occiput ipsilaterally (peripheral MEP) in 14 healthy control subjects and in 26 patients with and without neurogenic dysphagia. Needle recordings obtained from the cricothyroid muscle of the larynx were also evaluated in six healthy subjects. RESULTS The cortical motor latency of CP sphincter muscle was 10.7+/-0.5 ms with an amplitude of 0.8+/-0.2 mV in healthy subjects. Both the latency and amplitude of CP-MEP were facilitated during swallowing. The peripheral MEP of the CP muscle was very stable in all normal subjects (5.1+/-0.3 ms; 1.3+/-0.3 mV) and swallowing did not influence these parameters. The cortically elicited CP-MEP was significantly longer than the cortical MEPs obtained from the cricothyroid muscle of the larynx. In 10 dysphagic patients with corticobulbar tract involvement (6 ALS and 4 pseudobulbar palsy) and with pathologic and hyperreflexic EMG of the CP-sphincter muscle, the cortical MEP of CP muscle of the upper esophageal sphincter could not be elicited, although the peripheral CP-MEPs were obtained. TMS never produced a swallowing movement in neither healthy subjects nor patients. CONCLUSION The CP muscle of the upper esophageal sphincter can produce MEPs by cortical TMS and by stimulation at the root/nerve levels of vagus nerve. The MEP latency values and central motor delay suggest that there is an oligosynaptic corticobulbar pathway to the motoneurons of CP muscles. When the pathway is affected by a pathology (i.e. ALS or pseudobulbar palsy) the CP sphincter becomes hyperreflexic due to disinhibition and the cortical MEP of the CP muscle disappears due to degeneration of the corticobulbar pathway. These mechanisms appear to be responsible for the pathogenesis of dysphagia.

Abstract
Vincristine, adriamycin, and dexamethasone (VAD) chemotherapy protocol is first-choice treatment in newly diagnosed multiple myeloma patients in many centers. Sudden hearing loss associated with vincristine therapy is a rarely observed event in the VAD protocol. We describe a 69-year old male patient diagnosed with multiple myeloma 7 months ago who developed sudden bilateral hearing loss related to vincristine therapy. This uncommon adverse effect of vincristine is discussed and the literature reviewed.

Abstract
The effect of the topical anaesthesia of the oropharyngeal mucosae was studied in order to evaluate the role of the mucosal sensory receptors on the oropharyngeal swallowing in 12 adult volunteers. Laryngeal vertical movements were detected by a piezoelectric sensor and electromyography of the submental muscle complex were simultaneously recorded. All subjects were instructed to swallow doses of water, gradually increasing in quantity from 3-20 mL and any recurrence of the signals related to swallowing within 8 s was accepted as a sign of dysphagia and its limit value measured. Before the topical anaesthesia of the oropharyngeal mucosae by xylocaine puffs; the dysphagia limit was never observed with less than 20 mL water. During topical mucosal anaesthesia lasting 4-6 min among the subjects, the dysphagia limit was less than 20 mL water and the recurrence of swallows two or more times was mainly recorded with 3-5 mL water. Five of the subjects demonstrated the clinical and electrophysiological signs of laryngeal aspiration at the earlier period of the topical anaesthesia. It is concluded that the sensory inputs from the mucosal receptors are important to trigger voluntary swallowing and their absence or dysfunction may contribute to oropharyngeal dysphagia and laryngeal aspiration.

Abstract
UNLABELLED The addition of a brief alpha interferon regimen to each CHOP induction cycle, plus one year of alpha interferon thrice weekly maintenance therapy, has no early effect on response rates or survival in patients with Intermediate or High grade cell NHL. BACKGROUND The CHOP (Cyclophosphamide, Adriamycin. Vincristine, Prednisone) regimen is the most widely used first-line therapy for patients with Intermediate or High Grade (IG/HG) non-Hodgkin's lymphoma (NHL). Alpha 2b interferon (INF) enhances response rates and improves survival in low-grade NHL. The International Oncology Study Group (IOSG) conducted a prospective randomized study comparing CHOP alone or combined with INF in patients with IG/HG-NHL. The primary study aim was to compare the objective response rates in these patient cohorts. PATIENTS AND METHODS Patients with a confirmed diagnosis of measurable NHL of International Working Formulation (IWF) groups D to H histology were randomized to receive CHOP alone or CHOP with 5Mu INF s.c. for 5 days on days 22 to 26 of each 28 day cycle with INF 5 million units (Mu) given three times per week subcutaneously for 52 weeks in those patients who responded to CHOP plus INF. RESULTS The overall response rates were equivalent in both groups: CHOP alone (214 patients) 81% (complete 55%, partial 26%); CHOP plus INF (221 patients) 80% (complete 54%, partial 26%). At 36 months, the actuarial survival rate was equivalent in both groups. CONCLUSIONS There is no apparent early advantage in terms of response or survival conferred by adding the study INF regimen to CHOP therapy for patients with IG/HG-NHL.

Abstract
Brucellosis can present initially with its haematological findings including anaemia, leukopenia, and thrombocytopenia and may mimic primary haematological diseases. We present two patients with complaints of severe epistaxis and isolated thrombocytopenia which was initially diagnosed as idiopathic thrombocytopenic purpura but which was finally attributed to brucellosis. Their platelet count reverted to normal within 2-3 weeks of initiating antibrucellosis treatment with recovery from the disease.

Abstract
BACKGROUND The basic histopathological finding in gastric mucosa is chronic atrophic gastritis in patients with pernicious anemia. MATERIALS AND METHODS We evaluated the frequency of Helicobacter pylori and pathological examinations of gastric mucosa in pernicious anemia (n = 30) by endoscopical findings and biopsy. The results were compared with gastric mucosa specimens of patients with H. pylori-positive nonulcer dyspepsia (n = 36) and H. pylori-negative nonulcer dyspepsia (n = 21). RESULTS H. pylori was diagnosed in 12 patients (40%) with pernicious anemia. Fundal biopsy examinations showed atrophic gastritis in 30 patients (100%), intestinal metaplasia in 13 patients (43.3%), lymphoid follicle in 15 patients (50%), and dysplasia in 6 patients (20%). Antral biopsy examinations showed atrophic gastritis in 8 patients (26.6%), intestinal metaplasia in 8 patients (26.6%), lymphoid follicle in 8 patients (26.6%), and dysplasia in 3 patients (10%). The frequency of fundal inflammation, atrophy, intestinal metaplasia, lymphoid follicle, and dysplasia and antral intestinal metaplasia and mild antral dysplasia were found to be higher in those in the pernicious anemia group than in the nonulcer dyspeptic patients. Antral inflammation, atrophy, and moderate and severe antral dysplasia were found to be higher in those in the nonulcer dyspeptic group. CONCLUSIONS Particularly, fundal precancerous lesions were found to be more frequent in patients with pernicious anemia independent of H. pylori.

Abstract
Iron deficiency anemia is a cause of reactive thrombocytosis. A moderate increase in platelet numbers is common but sometimes counts may exceed 1,000 x 10(9)/l. The mechanisms causing reactive thrombocytosis are unclear. In this study, we evaluated 15 women with iron deficiency anemia and thrombocytosis (platelets >450 x 10(9)/l) and 16 women with iron deficiency anemia with normal platelet counts. Serum samples were taken before oral iron replacement therapy, after 1 and 3 months and at the end of replacement therapy. Thrombopoietin, erythropoietin (EPO), leukemia inhibitory factor, interleukin-6 and interleukin-11 levels were assayed. There was no change in the levels of thrombopoietic cytokines except for EPO. The correlation between high EPO levels and high platelet counts may suggest that EPO increases platelet counts, but the same EPO level changes can also be demonstrated in women with iron deficiency anemia but normal initial platelet counts. The fact that the levels of other cytokines remained unchanged during treatment suggests that either these cytokines have no effect on reactive thrombocytosis or the change in platelet counts in our patients is in a narrow range and is thus not affected by the cytokine levels.

Abstract
BACKGROUND AND PURPOSE The objective of the present study was to investigate the neural mechanisms of dysphagia in suprabulbar palsy (SBP) with multiple lacunar infarct. METHODS We evaluated the swallowing disorders of patients with SBP (n=34) and age-matched healthy control subjects (n=35) by means of an electrophysiological method that recorded the oropharyngeal swallowing patterns. With this method, dysphagia limit, the triggering of voluntarily initiated swallows, duration of laryngeal relocation time, and total duration of oropharyngeal swallowing were recorded and measured. In addition, the EMG behavior of the cricopharyngeal (CP) muscle of the upper esophageal sphincter was also assessed. RESULTS In patients with SBP, the dysphagia limit in all except 1 patient was pathological with limits of <20-mL bolus volume, which is contrary to normal subjects, in whom the dysphagia limit exceeds the 20-mL bolus volume. Either triggering of swallowing reflex was delayed (P<0.04), or the swallow could hardly be triggered in 7 patients on the voluntary attempts for 3 mL water. Whenever the reflex swallowing could be triggered, it was slow and prolonged (P<0.01). The CP muscle of the upper esophageal sphincter appeared to have become hyperreflexic and incoordinated with laryngeal movements during swallowing. CONCLUSIONS It was proposed that the progressive involvement of the excitatory and inhibitory corticobulbar fiber systems linked with the bulbar swallowing center is mainly responsible for the triggering difficulties of the swallowing reflex and for the hyperreflexic/incoordinated nature of the CP sphincter. In addition, the dysfunction of the extrapyramidal system has a specific role in the slowing of oropharyngeal swallowing and the accumulation of saliva in the mouth.

Abstract
A prospective randomized international study of 143 patients showed no apparent early survival advantage conferred by combining cytarabine, rather than hydroxyurea, with INF as first-line CML therapy. Combinations of alpha-interferon (INF) and chemotherapeutic agents are currently first-line therapy for the majority of patients with chronic myeloid leukemia (CML). The International Oncology Study Group conducted a prospective randomized study comparing INF combined with hydroxyurea or cytarabine. The primary study aim was to compare the survival durations in these patient cohorts. Patients with early chronic phase CML were randomized to receive INF 5 million units (Mu) given five times per week subcutaneously plus hydroxyurea or cytarabine as required to achieve a complete hematologic response and to maintain a WBC count between 2x10(9)/L and 10x10(9)/L and a platelet count between 75x10(9)/L and 100x10(9)/L. Therapy continued as tolerated unless progressive or blast phase disease occurred. At 36 months, the actuarial survival rate was equivalent in both groups: HI group (79 patients) survival was 85% (95% CI, 68-100%), as compared to 95% (95% CI, 79-100%) in the CI group (64 patients). In conclusion if seems that there is no apparent early survival advantage conferred by combining cytarabine, rather than hydroxyurea, with INF as first-line CML therapy.

Abstract
We investigated the pathophysiological mechanisms of dysphagia in amyotrophic lateral sclerosis. Forty-three patients with sporadic amyotrophic lateral sclerosis were examined by clinical and electrophysiological methods that objectively measured the oropharyngeal phase of voluntarily initiated swallowing, and these results were compared with those obtained from 50 age-matched control subjects. Laryngeal movements were detected by a piezoelectric sensor and EMG of submental muscles, and needle EMG of the cricopharyngeal muscle of the upper oesophageal sphincter of both the amyotrophic lateral sclerosis and control groups was recorded during swallowing. Amyotrophic lateral sclerosis patients with dysphagia displayed the following abnormal findings. (i) Submental muscle activity of the laryngeal elevators, which produce reflex upward deflection of the larynx during wet swallowing, was significantly prolonged whereas the laryngeal relocation time of the swallowing reflex remained within normal limits. (ii) The cricopharyngeal sphincter muscle EMG demonstrated severe abnormalities during voluntarily initiated swallows. The opening of the sphincter was delayed and/or the closure occurred prematurely, the total duration of opening was shortened and, at times, unexpected motor unit bursts appeared during this period. (iii) During voluntarily initiated swallows there was significant lack of co-ordination between the laryngeal elevator muscles and the cricopharyngeal sphincter muscle. These results point to two pathophysiological mechanisms that operate to cause dysphagia in amyotrophic lateral sclerosis patients. (i) The triggering of the swallowing reflex for the voluntarily initiated swallow is delayed and eventually abolished, whereas the spontaneous reflexive swallows are preserved until the preterminal stage of amyotrophic lateral sclerosis. (ii) The cricopharyngeal sphincter muscle of the upper oesophageal sphincter becomes hyper-reflexic and hypertonic. As a result, the laryngeal protective system and the bolus transport system of deglutition lose their co-ordination during voluntarily initiated swallowing. We conclude that these pathophysiological changes are related mainly to the progressive degeneration of the excitatory and inhibitory corticobulbar pyramidal fibres.

Abstract
OBJECTIVE To evaluate dysphagia at the oropharyngeal stage of swallowing and to determine the pathophysiological mechanisms of dysphagia in patients with myasthenia gravis. METHODS Fifteen patients with myasthenia gravis with dysphagia and 10 patients without dysphagia were investigated by a combined electrophysiological and mechanical method described previously. Laryngeal movements were detected by a piezoelectric transducer and the related submental EMG (SM-EMG) and sometimes the EMG of cricopharyngeal muscle of the upper esophageal sphincter (CP-EMG) were recorded during dry or wet swallowing. The results of these electrophysiological variables were compared with those of normal age matched control subjects. RESULTS In patients with myasthenia gravis with dysphagia, it was found that the time necessary for the larynx to remain in its superior position during swallowing and swallowing variability in successive swallows increased significantly compared with normal subjects and with patients with myasthenia gravis without dysphagia. The total duration of SM-EMG activity was also prolonged in both groups but more severely in the dysphagic patients. Electromyographic activity of the CP sphincter was found to be normal in the dysphagic patients investigated. All the patients with myasthenia gravis with dysphagia had pathological dysphagia limits (<20 ml water) whereas other patients except two, were within normal limits. CONCLUSIONS Because the electrophysiological variables related to oropharyngeal swallowing were prolonged even in patients with myasthenia gravis without dysphagia, it is concluded that the submental and laryngeal elevators are involved subclinically in myasthenia gravis and, because of compensating mechanisms, the patient may not be dysphagic. As the CP-EMG behaviour was found to be normal, a coordination disorder between normal CP sphincter muscle and the affected striated muscles of the laryngeal elevators may be one of the reasons for dysphagia in myasthenia gravis. This method also made it possible to investigate the myasthenic involvement in the laryngeal elevators that cannot be evaluated by other electrophysiological methods in myasthenia gravis.

Abstract
Anemia is the major stimulus for erythropoietin (Epo) secretion. Various studies have reported increase of Epo following chemotherapy. The mechanism of this phenomenon is not yet clarified. In this study, the serum Epo levels have been evaluated before, during (7 and 14 days), and after (day 25) chemotherapy in patients with acute myeloblastic leukemia (n = 13) and lymphoblastic leukemia (n = 4). As a control group, 12 healthy age-matched subjects were evaluated. Epo levels were high in untreated leukemia patients compared to controls and continued to increase following chemotherapy. There was no significant difference in post-treatment values of Epo as compared with pre-treatment levels. In patients with pre-treatment values of Hb < or = 9 g/dl, Epo levels were inversely correlated with Hb (r = 0.552; p < 0.05). This correlation disappeared during and following treatment. There was no correlation between Epo levels and hematological or biochemical parameters. Therefore, elevated levels of Epo regardless of anemia may be due to a response to tissue hypoxia or increased synthesis of Epo in liver or bone marrow.

Abstract
OBJECTIVE Swallowing mechanisms and neurogenic dysphagia have not been systematically studied by the EMG technique. It is desirable to evaluate neurogenic dysphagia for diagnostic and possibly for therapeutic purposes using electrophysiological methods. METHODS The following methods were described: mechanical upward/downward movements of the larynx were detected using a piezoelectric sensor, while submental integrated EMG activity was recorded during dry and wet swallowing. The EMG activity of cricopharyngeal muscle of the upper oesophageal sphincter was also recorded in some normal subjects and patients. Piecemeal deglutition and the dysphagia limit were determined in all patients to detect dysphagia objectively. In this study 75 normal subjects and 177 neurological patients with various degrees of dysphagia were investigated. RESULTS Voluntarily triggered oropharyngeal swallowing was commonly pathological in the majority of patients, with or without overt dysphagia. The dysphagia limit appeared to be an objective measure of the degree of dysphagia in more than 90% of patients. Pathophysiological mechanisms were different in at least three groups of patients with neurogenic dysphagia. In the group of patients with muscular disorders, laryngeal elevators were involved while the CP-sphincter was intact. The second group included patients with the clinical signs of corticobulbar fibre involvement such as amyotrophic lateral sclerosis and pseudobulbar palsy. In these patients, there was incoordination between paretic laryngeal elevators and hyperreflexic CP-sphincter. In the third group (patients with Parkinson's disease), the swallowing reflex was delayed and prolonged. CONCLUSIONS EMG methods described in the present study are very useful for the diagnosis of neurogenic dysphagia, objectively and quickly. They are important to understand the physiological mechanisms for deglutition and its disorders.

Abstract
In recent years, more effective and less toxic treatment protocols have been developed to increase the cure rates in intermediate and high grade non-Hodgkin's lymphoma (NHL). This study was undertaken to investigate the efficacy and toxicity of MINE (ifosfamide, mesna, mitoxantrone and etoposide) combination chemotherapy in patients with intermediate and high grade NHL. Twenty-one patients (16 male, 5 female; age between 26 and 70 years) with NHL were included in the study. An overall response rate of 73% and complete response rate of 56% were achieved and survival rate for responding patients was 80% at the 48th month. Side effects including mild myelosuppression, nausea/vomiting and alopecia were observed. MINE combination seems to be effective and well tolerated without significant toxicity as a first-line therapy in patients with intermediate or high grade NHL.
