Small bowel tolerance is a major dose-limiting factor in treating the pelvis with radiation therapy (RT). The use of small bowel contrast during RT simulation is one technique used to localize the bowel and identify the treatment plan that would exclude the greatest volume. To determine the influence of treatment planning with oral contrast on gastrointestinal injury, acute and chronic small bowel morbidity was analyzed in 115 patients with endometrial and rectal carcinoma who received postoperative radiation therapy at the Fox Chase Cancer Center. Mean and median time of follow-up were 31 and 27 months, respectively. Acute diarrhea was seen in 82% of the patient population. Ten percent of patients experienced major complications requiring hospitalization. Ninety-three percent of patients simulated without contrast experienced side effects compared to 77% of patients simulated with contrast (p = .026). There was an increased incidence of chronic complications in patients who were not simulated with contrast dye (50% vs 23%, p = .014). Median duration of minor side effects was 4 months for patients planned without oral contrast and 1 month for patients who had contrast at the time of simulation (p = .036). The superior aspect of the treatment field was determined to be at a more inferior location in patients simulated with contrast, thereby excluding small bowel from treatment. Seventy-four percent of patients simulated without contrast had the upper border of the field placed at the superior aspect of the sacroiliac joint or above, compared to only 40% of patients planned with oral contrast (p = .002). This study has demonstrated decreased complications (both overall and chronic) as well as a change in the location of the treatment field with the use of small bowel contrast. Multivariate analysis revealed that both the use of oral contrast (p = .026) and a lower superior border of the treatment field (p = .007) were predictive for fewer sequelae to RT, indicating that planning with contrast leads to changes in the technical delivery of RT other than field placement (e.g., block placement). The reduced incidence and duration of small bowel morbidity may be in part caused by alterations of the treatment plan made when the small bowel is visualized at the time of simulation. It is therefore recommended that oral small bowel contrast be used during treatment planning for pelvic irradiation.

A phase I study was conducted with dacarbazine (DTIC) protected from light and administered iv as a single dose every 3 weeks. Eighteen patients received 47 courses of DTIC, with doses ranging from 850 to 1980 mg/m2. Hypotension was the dose-limiting toxic effect and it may be secondary to the citric acid present in the pharmaceutic preparation of DTIC. Sporadic myelosuppression was seen at doses greater than 1380 mg/m2. Other side effects noted were nausea and vomiting, acute diarrhea, headache, a "flu-like" syndrome, and a hypersensitivity reaction to sunlight. No antitumor activity was found. The results of this study indicate that this may be a qualitatively different way of giving DTIC, and that the side effects of this drug may be intermingled with those of citric acid in this particular schedule. If the conventional pharmaceutic preparation of this drug is not modified, further studies with high-dose DTIC protected from light should be discouraged.

Clostridium difficile is well known for causing pseudomembranous colitis. Most cases are associated with the use of antimicrobial agents. Non-antibiotic associated colitis has rarely been reported. The causes of colitis are related to dietary changes, anesthesia, uremia, and various non-antibiotics medications, especially antineoplastic agents. Most responsible antineoplastics in previous reports are methotrexate and 5FU. From July 1993 to August 1994, 34 cancer patients developed acute diarrhea after chemotherapy. Six cases hd chemotherapy-associated colitis. All patients presented with moderate to severe diarrhea and demonstrable C.difficile toxin in fecal specimens and did not receive any antibiotics before the onset of diarrhea. Premier enzyme immunoassay (EIA) was used for toxin A assay because it is easy to perform and needs no special tissue culture laboratory facility. Data from multicenters studies have shown good sensitivity and specificity of the test. We found documented antineoplastics associated colitis, 7 episodes from 35 episodes of diarrhea (20.0%) that had been tested with EIA for toxin A. Five of 6 episodes were 5FU related. One patient had 2 episodes of antineoplastic associated colitis with the same chemotherapy regimen. The underlying malignancies were GI malignancies in 3 of 6 patients. In conclusion, moderate to severe diarrhea in cancer patients after chemotherapy should alert the physician to be aware of a potential fatal complication caused by C.difficile infection. True incidence has been undoubtedly masked by concomitant antimicrobial treatment and physician unawareness. Early recognition, discontinuation of chemotherapy and prompt treatment should be done to reduce morbidity and mortality of this disease.

Octreotide appears to have a major therapeutic effect in the management of diarrhoea related to cancer therapy. This effect is seen in the acute diarrhoea following radiation therapy and chemotherapy, and also in late radiation enteritis. As well as providing improved symptom control, early treatment can prevent potentially important morbidity in patients who are vulnerable to infection and fluid loss. Patients who suffer diarrhoea as a complication of AIDS, graft-versus-host disease and tumour-related diarrhoea can also obtain major benefit from treatment with octreotide. It should be considered as a first-line treatment in patients for whom diarrhoea may be a serious complication.

On the basis of the safety of the 1-h paclitaxel infusion schedule in prior studies we attempted to evaluate the feasibility of a shorter infusion schedule (< 1-h), given the general lack of published data or of attempts at applying this strategy. Before receiving paclitaxel, all patients were premedicated with promethazine, dexamethasone, and ranitidine; they were then given paclitaxel at a dose of 175 mg/m2 diluted in 150 ml normal saline. Four patients were evaluated, two with breast cancer, one with ovarian carcinoma, and one with non-small-cell lung cancer. All had received at least two prior cycles of paclitaxel and had never exhibited any hypersensitivity reaction. In all four patients, adverse signs and symptoms were observed at 5-15 min after the start of paclitaxel administration. These included generalized erythema (three patients), angioedema (all patients), sinus tachycardia (all patients), dyspnea (all patients), and increased sweating (all patients). One patient experienced acute diarrhea. Significant changes in vital signs were recorded in all patients, but there was no dysrhythmia or syncope. Thereafter, drug infusion was interrupted and supportive measures were initiated with dimethidene maleate, ranitidine, and methylprednisolone. In all patients, symptoms resolved over the next 15-30 min, and paclitaxel was reinstituted at the standard 1-h rate with no further sequelae. Paclitaxel administration in < 1 h did not prove to be safe in the current pilot experience and, therefore, cannot be recommended.

Cryptosporidium and isospora, two of the intestinal coccidian parasites known to be the causative agents of acute diarrhoea in animals, have now emerged as one of the main causes of prolonged life threatening diarrhoea in immunocompromised patients particularly so in patients with AIDS. Between June 1996 and December 1997, a total of 75 immunocompromised patients presenting with diarrhoea were investigated both for Cryptosporidium and Isospora. The study group consisted of cancer and AIDS patients with history of diarrhoea. Cryptosporidium oocysts were detected in 35 patients (46.7%). One of the faecal samples from an AIDS patient with diarrhoea showed the presence of both Cryptosporidium and Isospora oocysts. To the best of our knowledge, this is the second documented report of Isospora associated diarrhoea in an AIDS patient from India. The various techniques used for demonstration of these parasites were modified acid fast staining, Safranine Methylene-blue staining and direct immunofluorescence test.

Infections, malignancies and autoimmune diseases are the most important causes of fever of unknown origin.A case report of a 80-year old patient is described, who was admitted to our hospital because of fever lasting more than 2 weeks, weight loss and lack of appetite. Physical examination did not provide any relevant information, laboratory tests revealed an elevation of inflammation markers and anemia. Serological tests for infectious and autoimmune diseases and cultures of stool, blood and urine were all negative. Imaging did not show any pathological findings, colonoscopy and gastroscopy were macroscopically normal. Surprisingly, histology showed massive giardiasis of the duodenum. After initiation of therapy with metronidazol, fever and inflammation markers declined and the patient could be discharged from hospital without complaints on the 15(th) day after admission. Giardia lamblia is one of the most common intestinal pathogens worldwide. Infection can cause acute diarrhea, but may also be responsible for chronic abdominal complaints or may stay asymptomatic. To our knowledge, giardiasis has not been described as differential diagnosis of fever of unknown origin so far. In synopsis of clinical presentation and outcome after antibiotic therapy, we postulate that Giardia lamblia was the relevant cause of fever and weight loss in this case. In patients presenting with these symptoms, Giardia lamblia should be considered as differential diagnosis.

The Program of Information, Education, and Services for Basic Family Health Care in Magdalena Medio and Bajo was designed to increase knowledge and use of contraception and to improve basic health practices and nutrition in the region, which includes municipios belonging to 9 different departments and a total population of 1,720,000. Poverty levels in the area are high. During the 1st year of the project, which was underway from February 1988-May 1991, home visits were made to inform each family about basic family health, to weigh and measure children under 5 not receiving health care elsewhere, and to refer families to the nearest health services. Talks were presented to small groups on family planning, intestinal parasites, sexually transmitted diseases, nutrition, vaccination, cancer prevention, malaria, acute diarrhea, and acute respiratory infection. Community workshops were presented in the 2nd year. Community distribution posts were created for contraceptive and other health product distribution. Information and communication materials from PROFAMILIA were used, and other materials were specially designed for the project by the Foundation for Development of Health Education in Colombia. PROFAMILIA's system of service statistics was used for quantitative evaluation of the information and education activities and sales of contraceptives, antiparasitics, and oral rehydration packets of each instructor. In the 3 years of the program, 89.086 cycles of pills, 398,772 condoms, 29,080 vaginal tablets, 209.791 antiparasitics, and 49,305 oral rehydration packets were sold. 9295 talks were presented to 143,227 residents of the region. 22,000 children were enrolled in the growth monitoring program, and almost 40,000 women were referred for prenatal care and cytology. The instructors gave 900 talks to distributors of contraceptives, antiparasitics, and oral rehydration packets. Surveys of women aged 15-49 residing in the municipios covered by the project were conducted at the beginning and end of program activities in order to assess project impact. 1673 women were interviewed in the 1st survey in June-July 1988 and 1660 were interviewed in the 2nd survey in March-April 1991. In general terms, the region of Magdalena Medio and sand Bajo showed important changes in contraceptive prevalence, maternal-child health, knowledge of AIDS, and family violence over the 3 years of the project. Knowledge of contraception improved throughout the region, especially in rural areas. The proportion of women in union using a method increased from 56.7% to 58.0%. There were no overall changes in the proportions of children vaccinated.

A probiotic is a "live microbial food ingredients that, when ingested in sufficient quantities, exerts health benefits on the consumer". Probiotics exert their benefits through several mechanisms; they prevent colonization, cellular adhesion and invasion by pathogenic organisms, they have direct antimicrobial activity and they modulate the host immune response. The strongest evidence for the clinical effectiveness of probiotics has been in their use for the prevention of symptoms of lactose intolerance, treatment of acute diarrhea, attenuation of antibiotic-associated gastrointestinal side effects and the prevention and treatment of allergy manifestations. More research needs to be carried out to clarify conflicting findings on the use of probiotics for prevention of travelers' diarrhea, infections in children in daycare and dental caries, and elimination of nasal colonization with potentially pathogenic bacteria. Promising ongoing research is being conducted on the use of probiotics for the treatment of Clostridium difficile colitis, treatment of Helicobacter pylori infection, treatment of inflammatory bowel disease and prevention of relapse, treatment of irritable bowel syndrome, treatment of intestinal inflammation in cystic fibrosis patients, and prevention of necrotizing enterocolitis in premature infants. Finally, areas of future research include the use of probiotics for the treatment of rheumatoid arthritis, prevention of cancer and the treatment of graft-versus-host disease in bone marrow transplant recipients.

The management of advanced non-small cell lung cancer (NSCLC) has progressed over the last 3 decades due to advances in chemotherapeutic drugs and targeted agents improving survival and quality of life. In particular erlotinib, an orally available human epidermal growth factor receptor (HER1/EGFR) tyrosine kinase inhibitor advancing through clinical trials for the treatment of various human malignancies in a large placebo-controlled phase III study, has shown a significantly better OS vs. placebo suggesting its potential benefits in third line and possibly in second line treatments. The association of erlotinib with ionizing radiation has been recently published showing an enhancing antitumor activity and good tolerance. No information are available on side effects when erlotinib is associated with abdominal hypofractionated radiotherapy although diarrhoea is the most known side effect dose-limiting toxicity when the abdomen is treated. Here we report a fatal acute diarrhoea in a metastatic NSCLC patient taking erlotinib during abdominal hypofractionated radiotherapy for metastatic spinal cord compression (MSCC).
