The totally implantable catheter system has gained popularity as venous access when prolonged treatment is needed. Despite its frequent use, intravascular fracture and embolization of catheter fragments from implantable venous port-catheter systems present a rare but potentially life-threatening complication. Any implanted catheters should therefore be removed after completion of the treatment or the system's integrity should be monitored on a regular basis. This report illustrates such a case, which presented with ventricular tachycardia triggered by changes in body position from a fractured Mediport catheter with cardiac migration. A 34-year-old woman had a venous port catheter (Mediport) implanted into the right subclavian vein for neoadjuvant radio-chemotherapy for Hodgkin's lymphoma. Owing to the patient's difficult venous access the catheter was left in situ after treatment. Three years after insertion of the Mediport she presented with shortness of breath and palpitations when lying in the left lateral position. Physical examination revealed no abnormalities. An electrocardiogram was within normal rhythm. An outpatient Holter monitor revealed multiple episodes of nonsustained and sustained ventricular tachycardia triggered by lying in the left lateral position. A chest radiograph showed a normal location of the port-system, but the distal fragment of the catheter had embolized into the right ventricle. The embolized fragment was extracted with a gooseneck snare technique and the reservoir of the system was removed under local anesthesia without any complications. The patient was free of symptoms at 7 seven months follow-up.

Non-Hodgkins lymphoma spine metastasis is a rare entity. A woman in her mid fifties with history of non-Hodgkins lymphoma was admitted to the hospital with bilateral leg weakness, anesthesia, and incontinence. Magnetic resonance imaging of the spine showed diffuse metastatic disease involving the cervical, thoracic, lumbar, and sacral spine. She was treated with radiation therapy and high doses of corticosteroids. When discharged to home, she could ambulate with a rolling walker independently, was capable of self-catheterization, and could insert suppositories for a bladder and bowel program.

A 72-year-old lady was admitted to hospital with a large, bleeding mass on the right groin and an 8-month history of deep vein thrombosis of the left leg with pulmonary microembolisation treated medically. On clinical examination there was a solid, necrotising and bleeding right inguinal mass which extended 20 cm below the right inguinal ligament. A tissue biopsy, performed under local anaesthesia, revealed the presence of a non Hodgkin lymphoma with giant B-cells of follicular origin. An angio-CT scan of the pelvis and of the leg showed the compression of the 30 cm diameter tumour on the surrounding tissues. The mass appeared to be extra-compartmental and to have a non-homogeneous aspect with internal areas of necrosis and colliquation. Particular attention was devoted to the femoral vessels which were apparently not involved in the tumour mass. The patient was then operated on by a team of vascular and plastic-reconstructive surgeons. She underwent an operation consisting in an inguinal mass excision and skeletisation of the femoral vessels and nerve. The wound was then closed using both an abdominal and lateral flap from the hip. Postoperatively the patient made an uneventful recovery and was discharged from hospital on postoperative day 11. Follow-up at 3 months showed good healing of the wound and no signs of metastatic spread of the tumour.

The patient was a 38-year-old man. He had been suffering from hidradenitis suppurativa (HS) for approximately 20 years. He had active lesions at both axillas, hip, scrotum, and perineum, and inactive lesions located behind the ears, lower abdomen, and posterior neck. He was monitored and treated at different branches; he continuously used antibiotics and was given steroids at times. Antibiotic resistance developed subsequently. His general situation was bad; vital signs were poor; and he was in a state of sepsis and preshock, so this case was regarded as life-threatening. Total excision was performed first on the lesion at the right axilla, then on the lesion at the left axilla, and the parascapular fasciocutaneous flap was reversed. A skin graft was applied to the triangular defect on the scapula. No relapse occurred. Then the lesions at the hip were managed. Broad excision was used twice with the patient under general anesthesia; because the lesions spread to the retrococcygeal and gluteal muscles, coccyx resection and partial gluteal muscle resection were implemented. The defect was eliminated with a progressive flap. At the intergluteal sulcus, small lesions emerging at the median line were debrided with the patient under local anesthesia, and together with secondary recovery, the disease was completely managed. Lesions at the perineum and scrotum and at both inguinal areas were broadly excised and grafted. No lesion has relapsed so far. One year later, Hodgkin's lymphoma was diagnosed, and the patient was treated with chemoradiotherapy easily, because there was no infective focus. The disease is in remission now. The patient weighs 110 kg, is healthy, and is working again.

Nasopharyngeal malignancy accounts for less than 2 per cent of all head and neck cancers. Serous otitis media (SOM) causing deafness is a recognized indicator of nasopharyngeal obstruction and the possibility of a nasopharyngeal malignancy must be considered in all adults. Examination under anaesthesia (EUA) and biopsy of the nasopharynx is routinely undertaken in many centres to rule out nasopharyngeal malignancy in adults with SOM. The purpose of this 10-year retrospective study was to evaluate the case records of all adult cases of SOM, including their presentation, clinical findings, management and nasopharyngeal biopsy results. Eighty-five patients were included in the study. Fifty-nine presented with unilateral SOM and 26 with bilateral SOM. The primary presenting complaint in all cases was hearing loss. A nasopharyngeal mass was documented in 55 patients (69 per cent). Four nasopharyngeal masses were noted to have irregular or exophytic mucosa on flexible nasendoscopy. All patients underwent a EUA of the ears and a nasopharyngeal biopsy. The four patients with suspicious-looking masses were all found to have malignancies (two squamous cell carcinomas, one B-cell non-Hodgkin lymphoma and one adenocarcinoma). Three of these patients presented with unilateral SOM and one with bilateral SOM. All other patients with masses were found to have benign lymphoid hyperplasia. In total, 4.7 per cent of the adults with conductive hearing loss secondary to SOM were found to have a malignancy on nasopharyngeal biopsy. We would advocate a high index of suspicion of a nasopharyngeal tumour in adults presenting with SOM. If a mass is found in the nasopharynx then it should be biopsied. If no mass is found then it is not necessary to biopsy; however, close follow up, with repeat fibre-optic nasendoscopy, is advised.

Non-Hodgkin lymphomas belong to the neoplasms of lymphoreticular system. They derive form lymphocytes or their precursors, and cells that form as a result of lymphocytes' transformation. In most cases, the extranodular localisation of the neoplasm is alimentary tract, particularly the stomach. Less frequent locations are the ovaries, kidneys, adrenal glands, caecum, anus area, and retroperitoneal space. Also the region of the head and neck, especially the salivary glands, eyeballs, naso-fauces, maxillary sinus, should be considered when talking about extranodular localization. However lymphomas in those regions rarely penetrate the orbital and cranial cavity. In very few cases non-Hodgkin lymphomas locate themselves in the fundus of the oral cavity and lips. The aim of the study is to present a patient with rarely occuring lymphoma of the soft palate. First complaints of pain have been noticed 3 months before the patient arrived in our hospital, and gradually intensified themselves, which caused problems during meals. The patient has lost 5 kg of weight since the beginning of the disease, and suffered from profuse night sweating. In local anaesthesia a biopsy specimen has been taken for histological examination. The result of the examination was: MALT lymphoma, CD20, CD3. The patient was qualified for chemotherapy according to CHOP scheme, in the Chair of Oncology of Medical University in Lodz. Next, the patient has been transferred to the Department of the Radiotherapy. The patient completed the treatment in good condition.

General anesthesia in patients with mediastinal masses can lead to life-threatening cardiorespiratory complications. We report the cases of 2 pediatric patients with mediastinal masses who developed serious complications during general anesthesia. The first was a 13-year-old boy with a suspected diagnosis of high-grade T-cell non-Hodgkin lymphoma, lymph node disease, and an anterior mediastinal mass. He developed negative pressure pulmonary edema secondary to severe upper airway obstruction in spontaneous ventilation. The second was a 14-year-old boy with Rosai-Dorfman disease and paratracheal lymph node involvement. He developed severe airway obstruction in the early postoperative period. The anesthetic difficulties that arise in these cases include acute airway occlusion, superior vena cava syndrome, pulmonary artery or cardiac compression, acute pulmonary edema, and cardiopulmonary collapse. The technique of choice is induction with inhaled anesthetics and maintenance of spontaneous ventilation. Neuromuscular relaxants are avoided.

Primary pleural lymphoma is rare. It occurs in only 7% of lymphoma cases. We report herein two cases of primary pleural Hodgkin and non-Hodgkin follicular lymphomas diagnosed by thoracoscopy under local anesthesia. Both patients presented initially with dyspnea revealing pleural effusions. The pleural findings during thoracoscopy differed in the two cases and selective pleural biopsies under optical forceps led to the diagnosis of lymphoma. To date, primary pleural Hodgkin and non-Hodgkin follicular lymphomas have not been reported.

Propofol, like most general anesthetic drugs, can induce both behavioral and electroencephalographic (EEG) manifestations of excitation, rather than sedation, at low doses. Neuronal excitation is unexpected in the presence of this GABA(A)-potentiating drug. We construct a series of network models to understand this paradox. Individual neurons have ion channel conductances with Hodgkin-Huxley-type formulations. Propofol increases the maximal conductance and time constant of decay of the synaptic GABA(A) current. Networks range in size from 2 to 230 neurons. Population output is measured as a function of pyramidal cell activity, with the electroencephalogram approximated by the sum of population AMPA activity between pyramidal cells. These model networks suggest propofol-induced paradoxical excitation may result from a membrane level interaction between the GABA(A) current and an intrinsic membrane slow potassium current (M-current). This membrane level interaction has consequences at the level of multicellular networks enabling a switch from baseline interneuron synchrony to propofol-induced interneuron antisynchrony. Large network models reproduce the clinical EEG changes characteristic of propofol-induced paradoxical excitation. The EEG changes coincide with the emergence of antisynchronous interneuron clusters in the model networks. Our findings suggest interneuron antisynchrony as a potential network mechanism underlying the generation of propofol-induced paradoxical excitation. As correlates of behavioral phenomenology, these networks may refine our understanding of the specific behavioral states associated with general anesthesia.

We report the use of sugammadex to reverse a rocuronium block in a man who had received a kidney transplant 4 years earlier. The patient was admitted for gastric non-Hodgkins lymphoma and bleeding that required surgery. Arterial hypertension, tachycardia, and frequent ventricular extrasystoles were detected. Anesthetic induction was accomplished with propofol, fentanyl, and rocuronium; intubation was uneventful. We monitored pulse oximetry, capnography, heart rate, electrocardiography, arterial pressure (invasive), cardiac output, end-systolic volume, bispectral index, temperature, and neuromuscular function. Anesthesia was maintained with an infusion of propofol, fentanyl, and rocuronium guided by train-of-four (TOF) ratio. Total diuresis was 1100 mL. The operation lasted 4.5 hours. Recovery of neuromuscular response was spontaneous until the second TOF twitch, after which we injected 2 mg/kg of sugammadex. A TOF ratio of 0.94 was recorded 158 seconds after injection of the reversal agent. The patient was extubated without complications. Sugammadex can be used in patients with a transplanted kidney, provided the glomerular filtration rate has recovered sufficiently to allow full excretion of the sugammadex-rocuronium complex.
