Although thyrotoxicosis and orbital complications of acute ethmoid or frontal sinusitis are among the most common causes of unilateral exophthalmos, inflammatory pseudotumor is frequently accompanied by progressive acute unilateral proptosis. Because the associated chemosis, scleral erythema, and ophthalmoplegia constitute a spectrum of clinical findings present in numerous inflammatory orbital disorders and systemic diseases, the diagnosis of inflammatory pseudotumor is one of exclusion, often requiring orbital biopsy. Four patients without evidence of sinusitis, endocrinopathy, collagen vascular disease, or Wegener's granulomatosis are described. The diagnosis of orbital pseudotumor was disclosed by computed axial tomography, thus avoiding orbitotomy. The finding of scleral and choroidal thickening with enhancement following intravenous contrast injection represents a select group of patients with orbital pseudotumor and differentiates them from patients with endocrine exophthalmopathy or neoplasms. This noninvasive technique is extremely valuable because early diagnosis is critical for successful treatment. All four patients responded dramatically to high-dose corticosteroid therapy. In the absence of significant clinical response, however, Wegener's granulomatosis, lymphoma, and rhabdomyosarcoma, especially in younger patients, must be carefully excluded. Orbital exploration or decompression or both are used when proptosis, headache, or orbital pain does not resolve promptly, visual acuity deteriorates, or the diagnosis remains unknown.

Circumscribed heterotopic new-bone formation without a history of trauma is termed pseudomalignant myositis ossificans due to the diagnostic confusion of this benign lesion with malignant lesions. In 20 per cent of the published cases in which there were diagnostic problems, the patient underwent a radical procedure. Roentgenographically, pseudomalignant myositis ossificans is a circumscribed, radiopaque lesion with a central lucent zone that is separated from the underlying cortex by a radiolucent line. Histologically, a characteristic zoning pattern of peripheral maturation is present, the central proliferating zone usually causing the diagnostic problems. The ultrastructure of the lesion shows a regular mineralization front but an abnormal collagen periodicity of 300 angstroms. Excision is indicated for diagnosis and for relief of mechanical block or pain.

The use of free soft tissue autograft procedures has been well established and documented. However, little attention has been devoted to the care of the donor site which most frequently consists of palatal mucosa. The purpose of this study was to evaluate the hemostasis and protection of the palatal donor site of free soft tissue autografts using a microfibrillar collagen hemostat preparation. Twenty healthy adult subjects were selected. Ten patients in the experimental group received the microfibrillar collagen hemostat as a dressing while the control group received a conventional dressing. The results demonstrated that 10 minutes after the split thickness mucosal grafts were removed, the mean volume of blood absorbed by the sampling technique was 0.96 ml in the treated wounds vs. 1.85 ml in the control. There were no apparent differences in the quality of healing or the pain perceived by the patients in the experimental and control groups. It was concluded that the microfibrillar collagen hemostat produced rapid and effective hemostasis and protected the denuded palatal donor sites obviating the need for a conventional periodontal dressing.

Chronic Aspergillus meningitis and cerebral vasculitis occurred in a 67-year-old man. He experienced periorbital pain that increased in severity during a ten-month period. Although no focal neurologic deficits were initially present, oculosympathetic paresis, corneal hypesthesia, and optic neuropathy developed. This is the first report, to our knowledge, of paratrigeminal syndrome with optic neuropathy due to aspergillosis. The case was also unusual because it was chronic and there was no extracerebral infection or predisposing factors, such as underlying malignancy or collagen vascular disease.

Seven patients with atrophie blanche or livedo vasculitis of the lower extremities showed abnormal platelet functions in vitro. Six of seven showed hyperaggregation with epinephrine and/or collagen, three showed increased platelet adhesiveness, three showed increased platelet count, and one showed increased microemboli. After treatment with dipyridamole and aspirin, all showed return to normal platelet function. Clinical improvement occurred in all patients, with significant alleviation of pain and decrease in new lesion formation. Although enhanced healing of lesions seemed evident to physician and patient, it was incomplete. In two patients, pain returned when dipyridamole and aspirin were stopped, but the patients improved again when the medicines were restarted. These preliminary findings indicate a possible beneficial effect of antiplatelet therapy in atrophie blanche and livedo vasculitis. A double-blind study is being undertaken to further study this effect.

A 54-yr-old man was admitted to Hokkaido University Hospital, complaining of fever, multiple arthralgia, edematous erythema and face and muscular weakness of extremities during the last 2 months. He was diagnosed as dermatomyositis by acceleration of ESR, elevation of GOT, GPT, CPK, aldolase, moderate increases of collagen fibers in biopsy specimen of skin and his clinical signs. Although stools were positive for occult blood, the routine radiographic examination failed to detect the bleeding site in the upper GI. tract. However, in the double contrast picture of the stomach, a very fine abnormal linear shadow was observed at the upper corpus of the lesser curvature. This linear shadow was a margin of the tumor, retrospectively. About 4 months later, abnormal pain occurred and a mass was palpable in the left lumbar region, suggesting a pancreatic tumor. He was operated on excising the tumor, but was performed only exploratory laparotomy because of the presence of intra-abdominal metastases. Death occurred 40 days after the operation and necropsy was done. The gross anatomical findings of the abdomen showed a stomach tumor as large as an infant's head and its metastases to pancreas, lymph nodes, and greater and lesser omentum. Esophageal mucosa including esophagocardiac junction was intact. Histological examination of the intragastric tumor revealed a typical squamous cell carcinoma with keratinization. According to the absence of the components of adenocarcinoma and squamous metaplastic gastric mucosa of non-cancerous areas in the stomach, it seemed likely to be a heterotopic squamous cell carcinoma. It was unknown about the precedence between the stomach cancer and dermatomyositis. There have been 11 cases of primary pure squamous cell carcinoma in the world literature since 1968, but this is the first case report of coexistence of these two diseases.

The effect of the non-steroidal analgesic diflunisal on platelet aggregation and clinical haemorrhage at a dosage 250 mg twice or 3-times daily, sufficient to relieve musculo-skeletal pain and other painful conditions, was studied in 15 patients and 5 normal subjects. Platelet aggregation was carried out with ADP and collagen before and during treatment with diflunisal. The results indicated that diflunisal is an effective analgesic with no significant adverse effect on platelet function or clinical bleeding.

Infiltrative lipomas, similar to those described in man, were diagnosed in 12 dogs of various breeds, sexes, and ages. The neoplasms were poorly delineated, soft enlargements in muscle and connective tissue that caused dysfunction because of mechanical interference or pressure pain. The neoplasms consisted of differentiated fat cells that had infiltrated between or replaced muscle, collagen fibers or both. Single or multiple recurrences followed surgical removal in four of eight dogs: no follow-up was possible in the other four.

The in vitro test of direct granulation of basophils affected by specific antigens (cardial tissue, acid-soluble fraction of collagen, streptococcal allergens) was investigated in the course of treating 41 patients (29 women and 12 men aged from 20 to 50 years) suffering from a little active rheumatic fever. The patients received a complex of therapeutic measures including high-protein diet (130-140 g protein) and drugs (1.5-2.0 g acetylsalicylic acid and 15 mg of prednisolone a day). As a result of the treatment all the patients improved and demonstrated pain relief in the heart region, reduced palpitation, abatement of general weakness and fatigue. At the same time there was a decrease in the reactivity of basophilic leukocytes, shown by less number of degranulated cells in vitro, activated with specific antigens.

Six patients are described with idiopathic osteoporosis which began between the ages of 4 and 16 years. In four children the disorder was mild with pain in the back, vertebral collapse, qualitatively normal iliac bone biopsies, variable calcium balance and spontaneous recovery. The two remaining patients had progressive bone disease with deformity. One with a previously normal skeleton developed changes similar to those of osteogenesis imperfecta; in the other patient, who rapidly developed structural collapse associated with severe metaphysial osteoporosis, treatment was ineffective and the histological appearances of the bone suggested osteoblastic failure. Quantitative bone histology in four patients showed no evidence of excessive active resorption; and the ratio of Type III to Type I collagen in the skin was normal, in contrast to the findings in osteogenesis imperfecta. The significance of this study in relation to previous accounts is reviewed.
