An 8-year-old white girl with a history of vertigo, nausea, and vomiting developed a progressive hearing loss, bilateral retinal arteriolar narrowing in each eye, vasoproliferation, and subsequent intravitreal hemorrhage. An attempt at peripheral retinal ablation with cryotherapy in the left eye resulted in retinal detachment. Spontaneous retinal detachment occurred in the right eye and was successfully repaired. Repeated intermittent hemorrhages occurred despite intraocular diathermy. Three years after onset, visual acuity was R.E.: 6/21 (20/66) and L.E.: light perception. She remains totally deaf. A 20-year-old white woman developed severe bilateral sensorineural hearing loss with poorly functioning labyrinths, followed by midperipheral retinal arteriolar occlusions and vasoproliferation on the optic nerve head. Progressive retinal neovascularization was followed by rubeosis iridis and repeated episodes of intravitreal bleeding. Six years after onset, visula acuity was R.E.: hand motions, and L.E.: 6/3 (20/100). She remains totally deaf. Both patients were of normal gestation, development, and mentality, without evidence of other systemic disease. The cause of this disease was not found.

The clinical and pathologic features of 15 new cases of the uncommon primary or granulomatous angiitis of the central nervous system (PACNS) are described. To date, only 108 such cases have been reported in the English literature. Clinically, most PACNS patients have been young or middle-aged (mean age, 45 years; range, 3 to 96 years), with men outnumbering women slightly by a ratio of 4 to 3. The most frequent presenting complaints are headache, weakness, and confusion; less common complaints are aphasia, dysphasia, nausea or vomiting, loss of memory, and seizure disorder. There is usually no evidence of a systemic disease; the erythrocyte sedimentation rate is almost invariably normal, and there are no diagnostic laboratory tests. The cerebral angiogram usually shows multifocal, segmental stenosis or irregularity of small and medium-sized leptomeningeal and intracranial blood vessels, often with a beading or aneurysmal appearance, and alterations in blood flow in the affected regions. Anatomically, the angiitis is focal and segmental in distribution. An isolated negative biopsy, therefore, does not rule out the disease. Histologically, PACNS may be granulomatous, necrotizing, or lymphocytic in character, and mixed morphologic types often occur. Large- and small-vessel thrombosis is common. Acute lesions frequently coexist with healing or healed lesions. Involvement of extracranial blood vessels occurs only rarely. Past or current herpes zoster infection and Hodgkin's lymphoma are the most noteworthy clinical associations of PACNS, but whether they are causally related remains uncertain.

Dyspepsia can be defined as the presence of upper abdominal pain or discomfort; other symptoms referable to the proximal gastrointestinal tract, such as nausea, early satiety, and bloating, may also be present. Symptoms may or may not be meal related. To be termed chronic, dyspepsia should have been present for three months or longer. Over half the patients who present with chronic dyspepsia have no evidence of peptic ulceration, other focal lesions, or systemic disease and are diagnosed as having non-ulcer (or functional) dyspepsia. Non-ulcer dyspepsia is a heterogeneous syndrome. It has been proposed that this entity can be subdivided into a number of symptomatic clusters or groupings that suggest possible underlying pathogenetic mechanisms. These groupings include ulcer-like dyspepsia (typical symptoms of peptic ulcer are present), dysmotility (stasis)-like dyspepsia (symptoms include nausea, early satiety, bloating, and belching that suggest gastric stasis or small intestinal dysmotility), and reflux-like dyspepsia (heartburn or acid regurgitation accompanies upper abdominal pain or discomfort). The aetiology of non-ulcer dyspepsia is not established, although it is likely a multifactorial disorder. Motility abnormalities may be important in a subset of dyspepsia patients but probably do not explain the symptoms in the majority. Epidemiological studies have not convincingly demonstrated an association between Helicobacter pylori and non-ulcer dyspepsia. Other potential aetiological mechanisms, such as increased gastric acid secretion, psychological factors, life-event stress, and dietary factors, have not been established as causes of non-ulcer dyspepsia. Management of non-ulcer dyspepsia is difficult because its pathogenesis is poorly understood and is confounded because of a high placebo response rate. Until more data are available, it seems reasonable that treatment regimens target the clinical groupings described above. Antacids are no more effective than placebo in non-ulcer dyspepsia, although a subgroup of non-ulcer dyspepsia patients with reflux-like or ulcer-like symptoms may respond to H2-receptor antagonists. However, there is no significant benefit of these agents over placebo in many cases. Bismuth has been shown to be superior to placebo in patients with H. pylori in a number of studies, but these trials had several shortcomings and others have reported conflicting findings. Sucralfate was demonstrated in one study to be superior to placebo, but this finding was not confirmed by another group of investigators. Prokinetic drugs appear to be efficacious, and may be most useful in patients with dysmotility-like and reflux-like dyspepsia.

Surgery and radiation therapy are major treatments for carcinoma of the uterine cervix. However, there has been little improvement in survival recently. Since 1982, we have introduced multiagent chemotherapy consisting of cis-platinum, vincristine and peplomycin (CVP) to control systemic disease and to do cytoreduction prior to operation and/or radiation therapy. Our results are as follows. Thirty-one patients have been treated with CVP. Among eleven patients initially treated with CVP, 7 patients responded well to this regimen alone, including three patients who entered complete clinical remission. This indicates that this regimen is effective against carcinoma of the uterine cervix. Two patients who were thought to be candidates for radical hysterectomy became able to have less extensive surgery following CVP treatment. It is difficult for this CVP combination to control bulky tumors within previously radiated fields, probably because of poor vascularity due to pelvic fibrosis caused by radiation. Metastatic disease were also able to be controlled by this combination especially in two patients with pulmonary metastases. Nausea, vomiting and mild myelosuppression were frequently encountered, but they were tolerated well by the patients. However, great care must be taken in using peplomycin when the cumulative dose becomes large.

This paper has three parts: local anaesthetic adverse effects, haemorrhage control and altered immune response. Primary emphasis is placed on the problems with anaesthetics since their use is widespread. Every day, nearly 2 million injections of local anaesthetic are given in dental practice. From 2.5 to 10 per cent of patients experience adverse reactions. This adverse effect rate is 10 times higher than that in medicine for the same drugs. Allergic, toxic, idiosyncratic and psychogenic effects are discussed. New data on the role of local anaesthetic agents, vasoconstrictors and preservatives is presented. In addition, the problem of anaesthetic failure (occurring in over 10 per cent of patients) is explained. Treatment (drug and psychological) for anaesthetic related emergencies such as panic attacks, shortness of breath, palpitations and nausea is recommended. Prevention and treatment of haemorrhage is explained. Medical and dental conditions may increase clotting time (e.g., systemic disease or local factors such as granulation tissue). Preventive strategies are outlined and laboratory tests discussed. Emphasis should be placed on the use of local anaesthetics with vasoconstrictors, haemostatic agents and pressure. The final aspect of the paper discussed new data on problems for dentists arising with patients who have altered immune function. In particular AIDS is discussed from the point of view of protection of the dentist and dental treatment for the patient.

Adjustable suture surgery has become a popular method of strabismus correction in those cases in which results are less predictable, such as reoperations, thyroid ophthalmopathy, and blind eyes. Complications related to adjustable strabismus surgery are, in general, no different than those related to standard surgical techniques. We noticed a subgroup of patients who experienced significant vaso-vagal responses (V-VR) during postoperative adjustment and sought to discover a method of identifying these patients prior to adjustment. Sixty patients were studied prospectively from July 1991 to July 1992. All patients had surgery under general anesthesia and were adjusted 24 hours later. A positive oculocardiac reflex (OCR) occurred when a 10% or greater intraoperative change in heart rate was associated with traction on an extraocular muscle. A positive V-VR postoperatively consisted of one or more subjective findings (dizziness, light-headedness, nausea, or body temperature changes), and two or more objective findings (10% or greater change in heart rate, hypotension, pallor, diaphoresis, vomiting, disorientation, or loss of consciousness). Variables studied for predictive value included OCR, age, sex, strabismus type, previous surgery, muscle adjusted, and systemic disease. Twenty-five patients (41.6%) had a positive V-VR during adjustment. Twenty-seven patients (45%) had a positive OCR. Eighty-five percent of patients with a positive OCR and 9% of patients with a negative OCR had a positive V-VR. Younger patients were also more likely to have a positive V-VR. A positive intraoperative OCR under general anesthesia during strabismus surgery is highly predictive of a postoperative V-VR during planned adjustment.

We performed a preliminary phase II clinical trial of MX2; 3'-deamino-3'-morpholino-13-deoxy-10-hydroxycarminomycin (KRN8602) in patients with metastatic breast cancer who had failed to respond to previous chemotherapeutic regimens after clinical evidence of systemic disease. Twelve patients at a single institute received KRN8602 at a dose of 35 mg/m2 intravenously once every three weeks. All the patients were followed-up until their disease progressed. There was one complete response lasting 17 weeks and one partial response lasting eight weeks. Among the 12 patients, World Health Organization (WHO) grades 3 and 4 neutropenia were observed in five and two patients, respectively. Grade 3 anemia was observed in three patients but severe thrombocytopenia was not observed. Grade 3 nausea/vomiting was observed in eight patients. Alopecia was not observed. The results of this preliminary phase II trial suggest a need for further testing of the anti-tumor activity of KRN8602 in patients with metastatic breast cancer.

We reported previously that the addition of recombinant Escherichia coli human granulocyte-macrophage colony stimulating factor (GM-CSF) to a 5-fluorouracil (5-FU) and leucovorin (LV) regimen seemed to ameliorate diarrhea and permit increased 5-FU dose intensity (J. L. Grem et al., J. Clin. Oncol., 12: 560-568, 1994). We then tested the effect of GM-CSF given with a more toxic regimen of 5-FU/LV/IFN-alpha (IFN alpha-2a). Thirty-one patients with a good performance status and no prior chemotherapy for systemic disease received IFN alpha(-2a (5 MU/m2 s.c., days 1-7), 5-FU (370 mg/m2 i.v., days 2-6), LV (500 mg/m2 i.v., days 2-6), and GM-CSF (Saccharomyces cerevisiae 250 microg/m2 s.c., days 7-18) every 3 weeks. Toxicities and 5-FU dose intensity were compared with that observed in our prior Phase II trial with 5-FU/LV/IFN alpha-2a (J. L. Grem et al., J. Clin. Oncol., 11: 1737-1745, 1993). In comparison with the prior Phase II study, the WBC and granulocyte nadirs in the present trial were significantly higher. When trends in toxicity grades for all cycles were compared, stratifying for 5-FU dose, the incidence and severity of mucositis, skin rash, WBC toxicity, and granulocyte toxicity were significantly lower in the present trial, whereas nausea/vomiting and fatigue were significantly worse. The delivered 5-FU dose intensity for all cycles of therapy appeared to be significantly higher in the present trial. Six of 28 evaluable patients had a partial response (21.4%), and 13 (46%) had stable disease for > or =12 weeks. Despite treatment-related toxicity, patient quality of life did not worsen during the study. No correlation was observed between thymidylate synthase content in primary tumor specimens and response, time to treatment failure, or survival. The addition of GM-CSF appeared to decrease the severity of leukopenia, granulocytopenia, mucositis, and skin rash when compared with our prior experience with this regimen of 5-FU/LV/IFN alpha-2a, at the cost of greater nausea/vomiting and fatigue. The potential impact of increased 5-FU dose intensity on clinical response, however, remains to be determined.

Sarcoidosis is a systemic granulomatous disease of unknown etiology that is characterized by the formation of noncaseating granulomas. Gastrointestinal (GI) tract involvement in sarcoidosis is rare. Gastric sarcoidosis, particularly involving the antrum, affects approximately 10% of patients with systemic disease. GI sarcoidosis commonly occurs subclinically, with clinical manifestations present in only 0.1 to 0.9% of patients with the disease. This is a rare case report of an individual with symptomatic gastric sarcoidosis. The patient presented with weight loss, nausea, and early satiety. An EGD and colonoscopy were performed and were grossly normal. However, biopsies of the gastric antrum revealed noncaseating granulomatous inflammation involving the gastric mucosa. Corticosteroid therapy was started and the symptoms abated almost immediately. We also offer a review of the literature.

A 64-year-old woman with advanced esophageal cancer underwent chemotherapy with docetaxel/5-FU/CDDP (DFP). Adverse reactions were severe nausea and general fatigue, so the patient decided to discontinue DFP therapy. The treatment was changed to S-1/docetaxel. Adverse reactions were not so severe, so she could receive 1 course of the medication completely. After the treatment, the primary lesion showed a partial response, so we performed surgery. In the resected specimen, no malignant cell could be seen microscopically. Though the advanced esophageal cancer was regarded as a systemic disease, the appropriate combination of chemotherapy and surgery proved effective.
