Tense ascites may cause herniation of parietal peritoneal reflection into the mediastinum at the gastroesophageal junction. This may produce a mass visible on chest radiograph and computed tomography (CT). This communicating intrathoracic hydrocele may occur in the absence of hiatal hernia and may be confused with other middle mediastinal fluid collections including necrotic tumor, abscess, cyst of foregut origin, or pancreatic pseudocyst. Recognition of this entity in patients with ascites should prevent diagnostic confusion and unnecessary further evaluation.

The pathogenesis and diagnosis of cirrhotic ascites are reviewed, and the treatment options are described, focusing on pharmacologic management. The major theories on the pathogenesis of cirrhotic ascites are the underfill and overflow theories. The underfill theory states that ascites formation results in decreased plasma volume leading to renal sodium and water retention. The overflow theory states that the initial event in ascites formation is renal sodium retention. Evidence suggests that the formation of ascites is a continuum involving both overflow (early) and underfill (late) mechanisms. Although the most frequent cause of ascites is hepatic cirrhosis, analysis of the ascitic fluid is important to exclude other causes (e.g., neoplasm, peritonitis, pancreatitis). Patients who do not respond to treatment with sodium restriction and bed rest require diuretic therapy. Spironolactone is the agent of choice for treatment of the nonazotemic patient with cirrhotic ascites. Combination therapy with spironolactone and furosemide or spironolactone and metolazone may be used in those patients who do not respond to spironolactone. Patients with impaired renal function should not be treated with spironolactone because of the risk of hyperkalemia. Paracentesis with albumin replacement has been used successfully for treatment of patients with tense cirrhotic ascites. Initial management of cirrhotic ascites is conservative, with sodium restriction and bed rest. Spironolactone is a good first-choice drug for treatment of ascites. Daily weight, serum electrolytes, and renal function should be monitored to assess the effectiveness and potential adverse effects of diuretic therapy.

A case of cerebellar ganglioglioma is reported. A 22-year-old female was admitted to the Kurume University Hospital on August 19, 1985, suffering from headache, vomiting and gait disturbance. On admission, neurological examination revealed staggering gait and the right cerebellar ataxia showing dysmetria and dysdiadochokinesis. Mild choked disc in the right fundus was also noted. Plain CT scan showed the low-density area involving the right cerebellar hemisphere and the part of the vermis with internal hydrocephalus. Enhanced CT scan showed the high-density area adjacent to the low-density area suggesting a mural nodule. A vertebral angiogram in the arterial phase showed an expansive lesion in the posterior fossa and the tumor stain, which was also visualized in the venous phase. An emergency suboccipital craniectomy was then performed. With opening the tense dura mater, the cyst formation was noted and 30 ml of xanthochromic fluid was then aspirated. A well demarcated mural nodule was noted in the lateral wall of the cyst. The nodule was then extirpated in toto. The hypertrophy of the cerebellar cortex was not observed. Histologically, the tumor was consisted of nerve fiber, glial fiber and neuronal cells. Its architecture was differed distinctly from that of hamartomatous diffuse hypertrophy of the cerebellar cortex (Lhermitte-Duclos' disease). Immunohistochemically, the neuronal cells revealed positive staining for NSE and S-100, and the glial cells displayed positive staining for GFAP, S-100. The authors reviewed previously reported eleven cases of cerebellar ganglioglioma including the present case. These results showed that cerebellar gangliogliomas have some characteristic clinical features among general intracranial gangliogliomas.(ABSTRACT TRUNCATED AT 250 WORDS)

The author presented methods and results of ultrasonic diagnosis of concrements in intrahepatic (4), lobar (5), cystic (24) and common bile (20) ducts. In technically difficult cases the starting point of an acoustic shadow route was the only sign permitting concrement localization in the duct. Indirect signs of occluding choledocholithiasis were dilatated lumen of intrahepatic and proximal (with respect to the site of occlusion) extrahepatic ducts, a concrement filled cavity and the tense gall bladder wall, the absence of echographic signs of tumor involvement of the peritoneal cavity organs. The dilatation of the ducts and gall bladder cavity were more noticeable in patients with a long history of cholestasis. The lamination of the gall bladder content into zones of different echogenicity, the filling of the dilatated ducts with the content of inhomogeneous acoustic transparency indicated the complication of occluding choledocholithiasis by purulent cholangitis.

Primary breast cancer treatment is determined by tumor factors and by patient preference. Breast cancer treatments that preserve the cosmetic appearance of the breast are appealing and effective for appropriately selected patients; long-term survival following tumor excision and breast irradiation appears to be comparable to that for mastectomy. Since April 1981, when a protocol was developed and treatment options were offered, factors influencing treatment selection have been analyzed in 206 consecutive primary breast cancer patients. Mastectomy was dictated by tumor-related factors in 96 patients (47%); 110 patients (53%) had the option of mastectomy or conservation--tumor excision plus radiotherapy to the breast. Among these 110 eligible patients, 54 chose conservation (49%) and 56 chose mastectomy (51%). Intraoperative findings for ten patients electing conservation necessitated mastectomy, so conservation was accomplished for 44 (21%) of those treated for breast cancer. Beginning in July 1982, breast cancer patients took a battery of psychosexual assessments before any operation (Profile of Mood States [POMS], Health Locus of Control Scale [HLCS] Locke-Wallace Marital Adjustment Test [MAT], Psychosocial Adjustment to Illness Scale [PAIS], Derogatis Sexual Function Inventory [DSFI], Millon Clinical Multiaxial Inventory [MCMI], and a Breast Cancer Information Test [BCIT]). Comparisons of psychologic and demographic variables were made between patients who chose mastectomy and those who chose conservation. No demographic variable was statistically significantly related to choice, although older women tended to select mastectomy more than younger women. Compared with those who elected conservation, women who elected mastectomy were more tense and anxious (P less than .01), more introverted (P less than .01), felt more depressed and dejected (P less than .05), and reported more sexual problems (P less than .05). Those who elected conservation valued their physical appearance more highly (P less than .01) and were generally more self-interested (P less than .05). Mastectomy was dictated by medical considerations for approximately half of patients with breast cancer. Among candidates for breast conservation, the importance of retaining the breast appeared to be determined to a significant degree by measurable psychological factors.

Extraneural metastasis of intracranial ependymoma is a rare pathological entity. Thirty one case reports were traced in the review of the literature and we record one of them. The patient was a 19-year-old male in good health until January 1981 when he was admitted to our hospital with deteriorating mental status. Admission work-up revealed bilateral papilledema, 1-hemiparesis and increased intracranial pressure signs including vomiting. CT scan demonstrated significant abnormality of enhanced mass lesion in the r-temporo-parietal area in which a displacement of the midline structure to the left occurred. R-temporo-parietal craniotomy was performed on the admission day. The globular tumor mass occupied the temporo-parietal area and invaded the cortex. Subtotal resection of the tumor and temporal lobectomy was performed. Microscopic examination of the operative specimen revealed a typical ependymoma pattern. For the next two years, he received operations twice, irradiation (total 14, 170 rads) and various chemotherapy. Two months after the fourth craniectomy, examination revealed scalp overlying the burr opening to be very tense and enlarging as if invaded by the tumor. A large mass occupied the right lateral cervical area and chest X-ray disclosed complete opacity on the right. He gradually developed severe cough and sputum and died two months later on January 1, 1984. At autopsy, the result was that tumor had invaded the subarachnoidal space and subcutaneous area. Extraneural metastases were found to be bronchial lymph nodes, C-4 vertebra, r-cervical lymph node. The histological appearance of these tumors obtained at autopsy was identical to the cerebral tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical presentation of a congenital mucocele is a blue-gray tense mass located inferior to the medial canthal ligament. The differential diagnosis is that of tumor and encephalocele. Diagnostic modalities such as simple transillumination and ultrasound aid the physician, but dacryocystography confirms the marked lacrimal sac distension. In three infants the sac could not be decompressed by massage, indicating that the canalicular-punctal system as well as the inferior lacrimal system were blocked. When the distended lacrimal sac compresses the two canaliculi and bends them on themselves, there is a functional trapdoor-type block. During the probing of these patients, we felt a snap when the lacrimal syringe was withdrawn from the distended sac. We concluded that this was due to kinking of the canaliculus by the enlarged sac.

Axillary lymph nodes draining mammary carcinoma showed an alteration of both micro-architectue and lymphocyte subpopulations. Lymph nodes with a normal or increased T and/or B lymphocyte compartment (assessed by histology) had a low incidence of nodal tumour spread, whilst hypocellularity of the T- or B-lymphocyte-dependent areas was associated with a significant increase in metastatic invasion. Tumour-draining lymph nodes, in particular the more proximal ones, were often enlarged, spherical and tense due to an increased cellular content, predominatly B lymphocytes and their various subsets. The increased number and percentage of B lymphocytes was associated with follicular hyperplasia and prominent germinal centres. Lymph nodes with a prominent paracortex tended to have a higher ratio of T to B lymphocytes than nodes with a hypocellular paracortical area, but in many instances both the T- and B-lymphocyte-dependent areas were increased. There was no correlation between a particular axillary-node lymphocyte subpopulation pattern (assessed by surface markers) and the size, degree of necrosis, inflammatory infiltrate or histologic type of breast carcinoma, or the presence of metastatic node invasion.

Two cases are reported of upper limb rhabdomyolysis occurring after prolonged ENT cancer surgery, the patient being part of the time in the right lateral position, with the left forearm outstretched. Surgery consisted of a vertical hemilaryngectomy with immediate parascapular free graft reconstruction in a 48-year-old man (10 h of surgery, with 6 h in a lateral position) and the surgical removal of a neoplasm involving the mouth floor and larynx in a 62-year-old man including parascapsular free graft reconstruction (10 h of surgery, with 7 h in a lateral position). In the early postoperative period, the patients complained of severe pain in the left forearm. There was a tense painful swelling of the forearm, combined with an increase in creatinine kinase plasma concentration, and myoglobinaemia. The mechanism involved was most likely a compression of the forearm muscles, together with prolonged surgery and the patient position. The part played by the state of the patients is discussed. Diagnosis must be made as soon as possible, as the only efficient treatment consists of an early fasciotomy together with the administration of alkali to avoid renal failure.

The most common brain tumor that was present or produced symptoms at birth was teratoma. In this series of congenital tumors, teratomas occurred over 5 times more frequently than the second most common type, astrocytoma. They were often immature because of primitive neural elements and, rarely, a component of mixed malignant germ cell tumors. Incidence between sexes was nearly identical among histologic types that were reported at least 10 times, except for choroid plexus papilloma, which exhibited a male predominance. Four of five meningiomas occurred in males and 4 of 5 sarcomas in females. The predilection of neonatal brain tumors for supratentorial locations was also observed in this series of tumors present at birth. Teratomas occurred above the tentorium almost exclusively and all craniopharyngiomas and 14 of 16 choroid plexus tumors occurred supratentorially. At birth, large head or tense fontanel was a presenting sign in at least 55% of patients. Neurologic symptoms as initial symptoms were comparatively rare. Teratomas and craniopharyngiomas are tumors believed to arise because of developmental defects and these were the tumors that most often occurred with other anomalies. Anomalies were usually located in the head, with cleft lip or palate being most frequent. Prognosis for patients with brain tumors at birth was very poor, usually because of the massive size of the tumor. However, if small and favorably located, tumors were resected successfully. The most favorable outcomes were with choroid plexus tumors where aggressive treatment led to disease-free survival.
