In a randomized double-blind clinical investigation, the efficacy and safety of proglumetacin 450 mg/day (150 mg in the morning, 300 mg in the evening) were compared to those of piroxicam 20 mg/day (placebo in the morning, 20 mg in the evening), in 50 patients with activated gonarthrosis. After decoding it was found that 25 patients had been treated with proglumetacin and 25 with piroxicam. Joint troubles, knee circumference, function tests were recorded at time 0 and after 3, 7, 14 and 21 days; on the same days an overall doctor's rating of efficacy was also given. The rating of efficacy was "good" in 70% of patients in the proglumetacin group compared to 60% for piroxicam. The efficacy of the two medicaments was not significantly different. The patients treated with proglumetacin did not report any adverse reactions. Conversely, 5 patients of the piroxicam group dropped out: 1 for epigastric pain, 1 for vomiting and epigastric pain, 1 for an increase of severity of knee pain, 1 for an allergic reaction, 1 for an exanthema. The difference in drop-out rate is statistically significant. A further patient complained of gastrointestinal upsets, but continued on the treatment. Hematology and laboratory parameters were not affected by the treatments. It is concluded that in activated gonarthrosis proglumetacin has an efficacy comparable to that of piroxicam, but is significantly safer for the patients.

The authors experienced two elderly patients of megacolon associated with cerebral infarction and diabetes mellitus. The first patient was a 66-year-old female who was admitted to our hospital for rehabilitation with a complaint of knee pain. She had suffered from diabetes mellitus since she was 30 years old and multiple cerebral infarction since age 62. Two months after admission, she had an episode of abdominal distension and obstructive symptoms. The roentgenograms of her abdomen showed diffuse dilatation of the colon. The second patient was a 78-year-old female admitted to our hospital with complaints of abdominal pain, distension of the abdomen and vomiting. Her abdomen was severely distended and plain roentgenograms of the abdomen, X-ray studies of the colon with the aid of contrast medium and CT scan of the abdomen showed striking dilatation of the colon. Megacolon may be congenital or acquired, and in acquired forms the conditions are secondary to organic diseases, smooth muscle atrophy, metabolic and neurological diseases, ulcerative colitis or psychogenic origin (idiopathic). The two patients in this series were suffered from cerebral infarction and diabetes mellitus. The mechanisms of megacolon seen in these two patients are not known, but involvement of the visceral autonomic innervation is presumed. Some elderly patients have chronic constipation, and dilatation of the colon may not be uncommon due to underlying diseases or drugs. Therefore, when examining elderly patients, careful attention should be paid to their bowel movement.

Clinical research can be influenced by many factors that are capable of invalidating results, and one of these factors is known as the Hawthorne effect: the mere awareness of being under observation can alter the way in which a person behaves. In experimental research this effect can be the undesired effect of the experiments themselves, and the stronger its presence, the greater it can influence the results. In anesthesia practice, owing to the particular emotional condition of a patient facing a surgical operation, the Hawthorne effect could be especially strong. The aim of our study was to show the impact that the knowledge of being included in a study has (Hawthorne effect), by comparing the postoperative changes in psychological well-being in two groups of patients undergoing knee arthroscopy and receiving different information about the study from the anesthetist during the preoperative interview. Other signs and symptoms such as postoperative knee pain, nausea, vomiting (the most feared occurrences), headache, return of spontaneous diuresis, analgesic request, anesthesia complications, as well as the intensity of anxiety were also assessed as secondary endpoints. Our results show that subjects who were aware that they were part of a study scored significantly better on postoperative measures of psychological well-being and postoperative knee pain, compared to subjects who were unaware. The size of the effect, as measured by the odds ratio, remains unchanged when controlling for potential confounding factors. The study has enabled us to demonstrate the presence of the Hawthorne effect in clinical research. Therefore, the Hawthorne effect should be acknowledged and accounted for in the design of a study and in the interpretation of results.

Abdominal pain is common feature of Henoch-Schonlein purpura, which may mimic appendicitis, leading to unnecessary laparotomy. Accordingly, the diagnosis must be confirmed by ultrasonography or computed tomography scan before laparotomy is performed. The authors report a case of simultaneous occurrence of Henoch-Schonlein Purpura and gangrenous appendicitis in an 18 year-old boy. The patient was admitted with abdominal pain, cramps, and mild dehydration. He also complained of small reddish purple on his lower limbs, bilateral knee pain, low-grade fever, as well as bloody stools. The symptoms subsided completely. Eight days later, he returned with nonbloody, nonbilious emesis, abdominal cramps, and right lower quadrant abdominal tenderness. Abdominal ultrasound evaluation was performed to rule out an intussusception but demonstrated appendiceal dilatation with a possible appendicolith without any evidence of intussusception. A laparotomy was undertaken, and appendectomy was performed for gangrenous appendicitis. Simultaneous occurrence of Henoch-Schonlein purpura and acute appendicitis is rarely observed. Clinical features of the patients may mislead the clinicians, resulting in delayed diagnosis or misdiagnosis. The use of ultrasonography and computed tomography scan would confirm the diagnosis before surgery.

A 67-year-old African-American male presented with nausea, vomiting, diarrhea, fever, and knee pain. Four sets of blood cultures were collected and resulted in the growth of Bacteroides fragilis in all anaerobic bottles. Later, a fluid and tissue sample from the patient's knee grew the same species of bacteria. The patient was placed on intravenous antibiotics to fight the infection.

Q fever caused by Coxiella burnetii usually presents asymptomatically or as an undifferentiated febrile disease and rarely as rash or other cutaneous manifestations of the disease. Here we present a 41-year-old male complaining of body ache, fever, nausea, malaise, bilateral knee pain and vomiting. Clinical examination revealed a notable erythematous blanching rash all over his body. Workup revealed positive serologic testing for C. burnetii and skin biopsy of the rash revealed leukocytoclastic vasculitis.

Methanol is a clear liquid with high toxicity. Methanol intoxication may result from accidental exposure, overconsumption of compounds containing methanol with suicidal intent, or following consumption of distilled and contaminated alcoholic beverages. This report describes a case of transdermal methanol intoxication, which is a rare condition. A 58-year-old woman presented with nausea, vomiting, weakness, diplopia and dizziness. On neurological examination, she only had diplopia. On physical examination, a hyperemic lesion with clear borders was found over the right knee. The patient's recent medical history revealed that four days prior to the onset of symptoms, she had covered her knee with a methanol-soaked bandage in an attempt to alleviate her knee pain. She had a high osmolar gap as well as high anion-gap metabolic acidosis (HAGMA). Methanol intoxication was suspected due to HAGMA and high osmolar gap. Serum methanol levels were subsequently measured and found to be 37.9 mg/ dL. The patient was treated with intravenous (IV) bicarbonate, IV ethyl alcohol and hemodialysis. She was discharged with no central nervous system or ophthalmologic sequelae. Methanol poisoning should be kept in mind in patients with diplopia and unexplained metabolic acidosis. Although most methanol intoxication cases occur after oral ingestion, it should be considered that methanol poisoning may occur transdermally.
