Thoracoscopic resection of a solitary pulmonary lymphangioma: Report of a case

We present herein the rare case of a young man who was found to have a solitary tumor in the right upper lobe of his lung by a routine chest X-ray. The tumor was removed by thoracoscopic surgery, and pathological examinations confirmed the diagnosis of a primary lymphangioma of the lung. A brief review of the available literature on this extremely rare type of benign tumor follows the case report.     

Efficacy of cefminox in the treatment of bacterial infections

In an open trial, 1841 patients were treated with mainly 1 g of cefminox twice a day in adults or 20-30 mg/kg three or four times a day in children for up to 14 days. The clinical efficacy was assessed in 1560 patients (1256 adults, 304 children) and the efficacy rates were as follows: 82.3% in respiratory tract infections (n:525), 85.7% in biliary tract infections (n:87), 66.4% in urinary tract infections (n:509), 92.1% in gynaecological infections (n:126), 88.1% in peritonitis (n:84), 74.9% in all infections (n:1560). The overall bacterial response rates in single infections were 81.5% (81.5% for Staphylococcus aureus, 98.4% for Escherichia coli, 98.6% for Haemophilia influenzae and 38.8% for Pseudomonas aeruginosa). The safety of cefminox was assessed in 1831 patients. Adverse side-effects were reported in 35 patients (1.9%), the most frequent being rash.     

Skullbase-penetrating injuries caused by umbrella tips: case reports

Two cases of skullbase-penetrating injuries caused by umbrella tips are reported. Case 1: 24-year-old male. Admitted with disturbance of consciousness, left hemiparesis, nasal bleeding, and laceration of left lower eyelid because of having been stabbed by an umbrella tip. Pupils and fundi revealed no definite findings. Plain skull X-ray showed turbid ethmoid sinus and fracture of planum sphenoidale. Cranial CT showed right putaminal hematoma with intraventricular hemorrhage and pneumocephalus. Increased ICP necessitated surgery two days after the injury. Dural laceration of planum sphnoidale, laceration of left optic nerve, right rectal gyrus contusion and rebleeding from the right lenticulostriate branch were observed. Dural plasty and removal of hematoma with external decompression were carried out. He had a good postoperative course, but left visual loss and left hemiparesis remained. Case 2: 29-year-old male. Admitted with excoriation of his right nostril because of having been stabbed by an umbrella tip, severe headache, and nasal discharge. Oculomotor palsy was observed as well as CSF rhinorrhea and meningeal irritability. Plain skull X-ray showed niveau in sphenoidal sinus, pneumocephalus, and fracture of sella turcica. His complaint disappeared after conservative therapy. We reviewed the literature and found only 4 similar cases. The skullbase, because of its anatomical character, is likely to be penetrated in orbital and periorbital injury caused by umbrella tips. Cases which include disturbance of consciousness have a poor prognosis. We hope the fact that umbrella tips can easily become life-threatening objects will come to the attention of the general public so that similar cases may be avoided.     

Cervical spinal cord compression in hereditary multiple exostoses

Spinal cord compression is an extremely serious complication of hereditary multiple exostoses (HME). A case of HME with compression of the cervical spinal cord is reported. Complete recovery following surgery was achieved. A review of the relevant literature revealed 51 previous cases of HME with cord/cauda equina compression. Most patients were under 30 years of age with more men affected than women. The family history was positive in 60%. The cervical and thoracic areas were predominantly affected, with the symptoms usually developing slowly. Recovery following surgery is to be expected in the majority of cases. In patients with HME and suffering from neurological symptoms, the possibility of spinal cord compression should be considered. Prompt diagnosis and surgical excision provide the best prognosis.     

Urinary excretion of glycine.prolile dipeptidile aminopeptidase, N-acetyl-beta-D-glucosaminidase, alanine aminopeptidase and low molecular protein in patients with renal cell carcinoma]

Urinary excretion of glycine.prolile dipeptidile aminopeptidase (GP-DAP), N-acetyl-beta-D-glucosaminidase (NAG), alanine aminopeptidase (AAP) and beta 2-microglobulin (beta 2-M), alpha 1-microglobulin (alpha 1-M) was studied preoperatively in 32 patients with renal cell carcinoma. The excretion indices of GP-DAP, AAP and NAG were significantly higher than those in the healthy control group. The excretion of these enzymes obviously reflected the degree of the tumor progression. However, positive rates were not remarkable (37% for GP-DAP, 37% for AAP and 28% for NAG). The excretion of beta 2-M and alpha 1-M was not increased in renal cell carcinoma patients.     

Suppression by adrenoceptor beta-agonists of vascular permeability increase and edema formation induced by arachidonate metabolites, platelet-activating factor, and tumor-promoting phorbol ester TPA

Air-pouch-type inflammation was induced by injecting sodium carboxymethyl cellulose solution containing leukotriene C4 (LTC4, 3.20 x 10(-7) M, 0.2 micrograms/ml) and prostaglandin E2 (PGE2, 5.68 x 10(-6) M, 2.0 micrograms/ml), platelet-activating factor (PAF, 1 x 10(-6) M, 0.52 micrograms/ml), or 12-O-tetradecanoyl phorbol 13-acetate (TPA, 1.62 x 10(-6) M, 1.0 micrograms/ml) into an air pouch made on the dorsum of rats. Vascular permeability and tissue edema formation were significantly increased by injecting the phlogogen solution. The histamine level in the pouch fluid was dramatically increased by injecting TPA but not by LTC4 and PGE2, or PAF. Injection of isoproterenol or procaterol with the phlogogen solution produced dose-dependent suppression of both vascular permeability increase and tissue edema formation. However, the TPA-induced increase in the histamine level was not suppressed in parallel with the decrease of vascular permeability or tissue edema formation. These results indicate that beta-agonists suppress vascular permeability response and local tissue edema formation not by inhibiting mast cell degranulation, but by inhibiting the reactivity of the local vasculature to chemical mediators such as arachidonate metabolites, PAF, and histamine and serotonin released from mast cells.     

The somatotopic localisation of the descending cortical tract in the cerebral peduncle: a study using MRI of changes following Wallerian degeneration in the cerebral peduncle after a supratentorial vascular lesion

We studied the effects of Wallerian degeneration in the cerebral peduncle shown by magnetic resonance imaging (MRI) following a supratentorial vascular lesion, to identify the somatotopic localisation of the descending cortical tracts. Patients with a lesion involving a large area of a cerebral hemisphere had an area of abnormal signal intensity in the whole cerebral peduncle, suggesting Wallerian degeneration of all the whole descending cortical tracts. With a small lesion confined to the precentral gyrus, corona radiata, or posterior limb of the internal capsule there was an abnormal signal at the centre of the peduncle, suggesting degeneration of the precentrospinal tract. Those with a small lesion confined to the paracentral gyrus had an abnormal area slightly lateral to the centre of the peduncle, suggesting degeneration of the parietospinal tract. Patients with a lesion of the parietal or temporal lobes, not including the paracentral or precentral gyri, corona radiata, or the posterior limb of the internal capsule, had an abnormal area laterally in the peduncle, suggesting degeneration of the parietopontine or temporopontine tract.     

Late results after total correction of tetralogy of Fallot: over 10 year follow-up

Late results after total correction of tetralogy of Fallot over ten year follow up of 84 patients were discussed. No late death was experienced and 95.1% of these patients are now in NYHA class I. Reoperations were performed in 7 cases (8.3%) in which six had had residual shunt and one had had sick sinus syndrome and had VVI pacemaker implantation. Ten cases had over 90% of ratio of right ventricular pressure to systemic pressure in systole in their cardiac catheterization about 40 days after correction. In spite of this high pressure ratio, all cases are now in NYHA class I. We conclude that there is a possibility of enabling to preserve pulmonary valve function by adopting smaller criteria than the Pacifico's criteria.
