[Activity of DPP III in human cerebrospinal fluid derived from patients with pain].

BACKGROUND: In the course of elucidating physiological roles of spinorphin, an endogenous regulator of enkephalin-degrading enzyme, we found that dipeptidyl peptidase III (DPP III) was contained in human cerebrospinal fluid (CSF). In this study, we examined the activity of DPP III in human CSF derived from patients with pain. METHODS: We used human CSF as specimen collected during operations under spinal anesthesia. Patients were divided into three groups, patients without pain (normal group), with acute pain, and with chronic pain. We measured DPP III activities in each group, using specific substrates, such as Arg-Arg-AMC. RESULTS: DPP III activity for human CSF in patients with acute pain was significantly lower compared with that in patients without pain (P < 0.05). Furthermore, DPP III activity correlated with APN activity, another spinorphin-degrading enzyme, in patients with pain (r = 0.444). CONCLUSION: These results indicate that DPP III may play a role in regulation of endogenous opioids, leading to pain modulation.

[Diagnostic criteria for chronic fatigue syndrome by the CFS Study Group in Japan].

Much interest recently has been given to chronic fatigue syndrome (CFS) in Japan as other countries. The CFS Study Group sponsored by the Ministry of Health and Welfare has been developed since April 1991, A diagnostic criteria for CFS was newly proposed by this group. The criteria is substantially based upon the working case definition, which was made by Holmes and colleagues in 1988. There are some modification from CDC working case definition; the criteria of probable cases of CFS was defined, and postinfectious CFS was also given.

[A case of advanced pancreatic cancer showing remarkable response to gemcitabine treatment].

A 46-year-old woman with a 3-month history of upper abdominal pain was referred to our hospital because of the presence of a pancreatic mass and multiple hepatic nodules on abdominal ultrasonography (US) and computed tomography (CT). We concluded that the patient had pancreatic cancer with multiple hepatic metastases on the findings of endoscopic retrograde cholangiopancreatography (ERCP) and fine needle aspiration biopsy of the hepatic nodule. The patient received gemcitabine treatment. Gemcitabine 1,000 mg/m2 was administered once a week for 3 weeks followed by a week of rest, this constituting 1 cycle of treatment. Partial responses (PR) of both pancreatic and hepatic lesions were observed after the first cycle of the gemcitabine treatment, and serum concentrations of CEA and CA19-9 remarkably decreased. We considered that clinical benefit was obtained because Karnofsky performance status improved and analgesic consumption decreased. Such effectiveness of the gemcitabine treatment lasted for the following 4 cycles. In general, chemotherapy has few effects on an advanced pancreatic cancer. We report a case of advanced pancreatic cancer that could obtain remarkable antineoplastic effect and clinical benefit with gemcitabine treatment.

[Measuring the degree of patient satisfaction treated at an extracorporeal lithotripsy unit].

OBJECTIVES: To determine by questionnaires the level of satisfaction of patients diagnosed of urinary lithiasis treated by extracorporeal shock wave lithotripsy (ESWL) in our Renal Stone Centre. METHODS: A total of 100 patients with urinary lithiasis who underwent ESWL, 54 males and 46 females with an average age of 50 years, answered a Lickert type questionnaire (score 1 to 5) consisting of 6 questions to evaluate the patient satisfaction regarding the treatment received. The relationship between answers to each question and patient's clinical characteristics were analyzed applying chi-square and linear regression to determine the level of significance of these relationships. RESULTS: General satisfaction level was high, with a mean score of 4.33 for the six questions. The most valued question was the one referred to assistance received in relation to the planned medical one. Questions referred to treatment suitability, expected timing, and absence of complexity were also highly valued. The least valued question was the one referred to pain level during treatment, which level was kept in a good approval degree with a mean score of 3.81 despite the fact that some patients said they suffered more pain than expected. CONCLUSIONS: ESWL resulted in a high level of satisfaction among patients treated for urinary lithiasis, revealed not only by its suitability, easy planning and performance, but also by its low level of complexity. Pain experienced by these patients during treatment was well-tolerated, so that general use of anesthesia was not required.

Rigid rectosigmoidoscopy: still a well-tolerated diagnostic tool.

BACKGROUND: Although rigid rectosigmoidoscopy has been gradually replaced by the use of flexible rectosigmoidoscopy in recent years, it remains an effective, economic and widely available diagnostic tool. The aim of this study was to determine the type and magnitude of symptoms during rigid rectosigmodoscopy. METHODS: Prospective evaluation of patients who underwent diagnostic rigid rectosigmoidoscopy. The main complaints were recorded, and their magnitude quantified using a visual analogue scale. RESULTS: A total of 134 patients (mean age = 48 years) were examined. The prone jackknife position was used in 54% of them and left lateral decubitus in 46%. A complete (full length) examination was achieved in 68%. There were no complications. Sixty percent of patients referred complaints: pain (33%), discomfort by rectal preparation (13%), uncomfortable defecation desire (8%), and discomfort by the position (4%). Median values determined by visual analogue scale for pain, discomfort by rectal preparation, uncomfortable positioning and overall discomfort were graded as 3.3, 3.3, 2.1 and 2, respectively. There was an association between higher magnitude of pain and overall discomfort with female gender, left lateral decubitus position, and full-length exploration (p < 0.05). CONCLUSION: A high percentage of patients have symptoms during rigid rectosigmoidoscopy but the study is usually well tolerated due the low magnitude of pain and discomfort and remains a very cost-effective study.

[Fatal evolution of a renal angiosarcoma].

OBJECTIVES: Report a new case of renal angiosarcoma treated by surgery and adjuvant chemotherapy with bad results. METHODS: 72-year-old male undergoing right nephrectomy for renal tumor. Pathology reports renal angiosarcoma. RESULTS: Three months after surgery patient refers lumbar pain and hemoptysis and CT scan reveals the existence of multiple bone and lung metastasis; a regimen of systemic chemotherapy with Doxorrubicine+ Ifosfamide was started without response; he died two months later. CONCLUSIONS: Primary renal angiosarcoma is very rare, with less than 10 cases in the literature before 1998, and it is always associated with bad prognosis. Diagnosis is based on immunohistochemical studies (antibodies against CD31, CD34 and factor VIII related antigen) to define the endothelial differentiation of the tumor. There is no experience to define the best therapeutic strategy against this entity.

Plasma tryptophan and other amino acids in primary fibromyalgia: a controlled study.

To test the hypothesis that plasma tryptophan and/or its transport ratio is decreased in primary fibromyalgia (PF), we measured plasma tryptophan and its transport ratio in 29 patients with PF and 30 healthy controls without significant pain, in a blinded manner. Twenty-one other amino acids were also similarly analyzed among these study subjects. Transport ratio of tryptophan was found to be significantly (p less than 0.01) decreased in PF compared with the control group (0.09 +/- 0.02 vs 0.10 +/- 0.02). Plasma tryptophan level was lower in PF (45 +/- 10 nmol/ml) than in healthy controls (51 +/- 15 nmol/ml), showing a trend towards significance (p less than 0.09). Additionally, plasma histidine and serine levels were found to be significantly (p less than 0.01) lower in patients with PF than in controls. Our results suggest that a decreased brain serotonin level, as possibly reflected by a decreased transport ratio of plasma tryptophan, may play a pathophysiologic role in PF.

Complete proximal occlusion of all three main coronary arteries complicated with a left main coronary aneurysm: a case report.

A 68-year-old woman with recurrent chest pain was referred to our institution. Coronary angiography showed 100% obstruction of the left main trunk, the proximal right coronary artery with good collaterals to the left anterior descending artery and left circumflex artery along the conus artery. Emergency surgical revascularization was undertaken with two saphenous vein grafts. The saphenous vein grafts were placed in the left anterior descending artery, obtuse marginal branch and the posterolateral and posterior descending coronary arteries with excellent flow. The postoperative course was uneventful and follow-up angiography was obtained 20 days after the surgery. Coronary angiography demonstrated a saccular aneurysm (10 x 9 mm) originating at the distal segment of the left main coronary artery with 90% stenosis, and excellent patency of both saphenous vein grafts. Follow-up angiography was performed 1 and 3 years after the surgery. The size of the left main coronary aneurysm remained unchanged at both examinations. The patient did well with no further cardiac symptoms after 5 years.

Gastric plasmacytoma and Helicobacter pylori infection.

A 59-year-old man with a history of melena and upper abdominal pain was referred to our hospital. An upper endoscopy was performed, and a gastric ulcer was found bordering the antrum and stomach body. Multiple biopsies from the lesion showed monoclonal plasmacytic infiltration of the mucosa, consistent with the diagnosis of plasmacytoma. Helicobacter pylori was also identified. Triple therapy failed and quadruple therapy eradicated the H. pylori, confirmed by repeated biopsies. Healing of the gastric lesion followed the treatment. Multiple biopsies from the scar and the entire stomach showed complete regression of the plasmacytoma. The association between gastric plasmacytoma and H. pylori is discussed.

[Echo-Doppler duplex combined with intracavernous injection of prostaglandin E1 in the diagnosis of impotence].

Sixty-two patients that had consulted for impotence were evaluated by intracavernal injection of prostaglandin E1 and duplex echo-Doppler. The internal diameter and the mean flow of the cavernosal arteries were determined by echo-Doppler in the flaccid state. Thereafter 20 micrograms of PGE 1 was injected intracavernously and the erectile response was evaluated clinically after 5 to 15 minutes. Another Doppler evaluation was performed during tumescence to study the changes of the internal diameter and the mean flow increase of the cavernal arteries. Twenty-nine patients (46.7%) achieved normal erection after intracavernal PGE 1 and the Doppler study was normal in all but 2 patients (3.2%). The remaining 33 patients (53.1%) failed to achieve normal erection following intracavernal injection of PGE 1. The Doppler study, however, was normal in 7 of these patients (11.2%), which indicates venous leak to be the underlying cause of impotence. There were minor complications (19.3%) presented a small hematoma at the site of injection and 12.9% referred moderate pain at the time of injection) and no patient has a sustained erection for more than 3 hours. The hemodynamic mechanisms and the current concepts relative to the neurologic aspects of erection are discussed. We believe duplex echo-Doppler combined with intracavernal PGE 1 to be a very reliable method in the diagnosis of impotence of a vascular origin. It can distinguish those patients that cannot achieve erection following intracavernal PGE 1 with a normal arterial tree whose impotence can be ascribed to venous leak.

[Primary carcinoma in situ of the upper urinary tract: a case report].

A case of primary carcinoma in situ of the upper urinary tract in a 72-year-old woman is reported. The patient who complained of left lower abdominal pain was referred for a suspicion of left ureteral stone. An excretory pyelogram showed mild left ureteral stricuture at the level of L3, but a stone was not detected in the ureter at the same level. Cytology of voided urine was positive for malignant cells several times. Cystoscopic examination revealed no abnormality in the bladder. Retrograde left pyelogram demonstrated the ureteral stricture and no lesions either of stone or tumor in the ureter. However malignant cells were detected cytologically in the left ureteral catheteral urine. Left total nephroureterectomy with the bladder cuff was carried out under the preoperative diagnosis of carcinoma in situ of the upper urinary tract. Macroscopically, the wall of the ureter at the stenotic level had induration without apparent tumor mass. The pathological diagnosis was transitional cell carcinoma in situ from the renal pelvis to the mid-ureter. The primary carcinoma in situ of the upper urinary tract is rare. To our knowledge, this case is the 26th case reported in the Japanese literature.

[Two cases of silicate urolithiasis].

Case 1: A 31-year-old woman with the chief complaint of right back pain was referred to our hospital. She was diagnosed with a right ureteral stone and it was delivered spontaneously after conservative medical therapy. The stone was found to consist of silicate by infrared spectrometry. Case 2: A 71-year-old man with the chief complaint of asymptomatic macrohematuria was referred to our hospital. No tumor was observed by cystourethroscopy, but a right ureteral stone was found by computerized tomography. Subsequently, it was delivered immediately and infrared spectrometry of the stone demonstrated silicate containing a small amount of calcium oxalate monohydrate. We analyzed and discussed 44 cases of silicate urolithiasis reported in Japan.

[Platelet-rich plasma (platelet gel) in secondary alveoloplasty in cleft patients].

INTRODUCTION: The use of Platelet-rich plasma (platelet gel--PRP--) was introduced in the oral and maxilofacial surgery 10 years ago. Its good results are due to the quickly generation of new bone and the acceleration of the period of surgical scar formation. Its employment in the alveolar reconstruction of the cleft patient is not still consistent and the works published in the literature are infrequent. The objective of this preliminary study is presenting our experience with the use of PRP in the reconstruction of the alveolar congenital defects of cleft patients. PATIENTS AND METHODS: Between July 2002 and January 2004 were operated 14 patients with congenital alveolar cleft carrying out an standard secondary alveoloplasty. In 12 cases was employed cancellous bone of iliac crest and in two cases the donor area was tibial. The laboratory of Hematology of our Hospital prepared the plasma gel rich in platelets by means of a double centrifuge of autologous serum of the patient. After adding calcium a rich gel in platelets in approximate quantities of 1-2 ml was obtained. In this preliminary report we have studied the aspect of the surgical injury the 3er postoperative day, and the first and second weeks after intervention. These results were compared carried out previously with the Standard alveoloplasty without use of the PRP. Likewise we evaluated the bony density by means of intraoral Rx at 3 and 6 months postoperative. RESULTS: The injury of the alveoloplasty healed more quickly in the patients in which plasma enriched gel was employed. The patients referred less pain and edema in the first days of the postoperative period. The alveolar bony regeneration was faster to the 3 months, though the result was similar in the intraoral Rx to the 6 months. The necessary quantities of cancellous bone were smaller in all cases in which the plasma enriched gel was used (30% less). CONCLUSIONS: The use of Platelet-rich plasma (PRP) is a valid protocol for the reconstruction in patients with congenital alveolar clefts. Its low price and morbidity do it recommendable for its employment in cleft patients.

Three-dimensional computed tomography and surgical treatment for Eagle's syndrome.

Eagle's syndrome represents a group of symptoms that includes recurrent throat pain, globus pharyngeus, dysphagia, referred otalgia, and neck pain possibly caused by elongation of the styloid process or ossification of the stylohyoid or stylomandibular ligaments. The medical history and physical and radiologic examinations are the main guides to the precise diagnosis. The radiologic diagnostic modality of choice is three-dimensional computed tomography (3-D CT). We describe a case of bilaterally symptomatic Eagle's syndrome that was diagnosed by 3-D CT of the styloid processes and successfully treated with surgery via a transoral approach.
