The non-steroidal anti-inflammatory drug (NSAID) Ketoprofen (Profenid) is used as intravenous monotherapy incorporated in 0.9% normal saline solution (100 mg Ketoprofen ampoule + 200 ml normal saline) in the treatment of renal colic. We present our experience in 65 patients complaining of clinically diagnosed renal colic who were treated by intravenous saline-Ketoprofen. Prospective investigations revaled urinary calculi in 51 patients, oxaluria (crystalluria) in 5, acute colitis in 2, severe myositis in 2, negative investigations in 3 and radiculitis in 2 patients. Positive response was observed in 93.8% of patients as far as pain relief is concerned. Pain relief started within 5-7 minutes after beginning the infusion. Duration of analgesic effect ranged between 4 and 12 hours. Repeating the injection was done for maintenance of analgesia. Side effects included drowsiness in 2 patients, palpitation in 1 patient, epigastric pain in 1, muscular cramp in 1 patient. Ketoprofen, an antiprostaglandin, is a powerful anti-inflammatory and potent analgesic. Intravenous saline-Ketoprofen is a good emergency treatment for acute episodes of renal colic.

We report a 25-year-old man presenting with high fever, dyspnoea and somnolence. The presence of severe diffuse interstitial pneumonia with extrapulmonary symptoms, such as myositis and subclinical haemolysis, strongly suggested an infection by Mycoplasma pneumoniae. This diagnosis was supported by high titres of cold agglutinins and a positive Coombs test, and directly confirmed by specific IgM serological tests. After initiation of the appropriate antimicrobial treatment mechanical ventilation could be avoided and the patient showed a slow but complete clinical recovery. This diagnosis should be considered in any febrile patient with hypoxaemia and diffuse interstitial pneumonia, and rapid initiation of appropriate antibiotic treatment seems to be crucial for a favourable outcome.

We report a 37-year-old woman with slowly developing muscular weakness for 2 years following insidious stiffness of calf muscle. Serum CK was elevated up to 4,207 IU/l. She presented sleepiness, weakness of proximal and truncal muscles and systemic muscular atrophy. While she had not experienced dyspnea, her arterial blood gas analysis revealed extreme hypoxia and hypercapnea due to weakness of respiratory muscles. Echocardiogram showed thinness and hypokinesis of left ventricular wall, and arrhythmia was pointed out by holter ECG. Needle elctromyogram of the proximal muscles exhibited polyphasic units with low amplitude. Muscle biopsy showed degeneration and necrosis of muscle fibers as well as regeneration. Mild infiltration of inflammatory cells was shown. Serological examination showed positive antimitochondrial M2 antibody, especially specific for primary biliary chirrhosis (PBC). She was diagnosed as chronic myositis associated with PBC. Four cases of idiopathic myositis with severe weakness of respiratory muscle, associated with PBC had been reported. These cases and our present case share the similar feature in respect of insidious or chronic course and resistance to therapy. In our present patient, respiration had been supported by BiPAP and she has been successfully improving slowly by oral steroid following 4 courses of methylprednisolone pulse therapy.

The purpose of this study was to determine the frequency of obstructive sleep apnea in patients with inflammatory myopathy. An observational and prospective study was performed on a cohort of adult patients with inflammatory myopathy followed at a specialized outpatient clinic. Sixteen consecutive adult patients were evaluated by the Epworth Sleepiness Scale (ESS) and by complete polysomnography study. Disease activity and severity were assessed using the Myositis Disease Activity Assessment Tool (MDAAT) and Myositis Damage Index (MDI), respectively. Associations between sleep parameters and other factors were calculated using the chi-square test, Fisher's exact test, Mann-Whitney U-test, and Wilcoxon's test. A serum autoantibody profile was determined for all patients. The mean apnea-hypopnea index was 28.7 (23.8), and 14 patients (87%) had an apnea-hypopnea index >5. The mean frequency of respiratory arousals was 20.1 (12.5). Eleven (68%) patients reported frequently-always snoring, and 3 (19%) had excessive daytime sleepiness (ESS >10). Seven patients were offered continuous positive airway pressure (CPAP) therapy; 4 tolerated the procedure well and reported a clear improvement in daytime sleepiness and/or sleep quality. No significant association was observed between the apnea-hypopnea index and clinical or immunological groups. Dysphagia, disease activity, and disease severity were not significantly associated with any sleep parameters. The frequency of obstructive sleep apnea in adult patients with inflammatory myopathy is high. The possibility that these alterations play a role in persistent fatigue in these patients cannot be ruled out.

Compartment syndrome may be acute or chronic based on the clinical course and etiology. Here, we report the first known case to be diagnosed with skeletal muscle-derived B-cell lymphoma presenting with chronic compartment syndrome after trauma. A 62-year-old woman sought medical attention due to a one-month history of painful left lower leg swelling and paresthesia of the medial side of the foot after falling over. The patient underwent fasciotomy and debridement under the preoperative diagnosis of fasciitis and myositis with associated compressive neuropathy. Preoperative laboratory tests were within normal limits. Postoperative pathologic examination and bone marrow aspiration revealed B-cell lymphoma with bone marrow involvement postoperatively. Tumor lysis syndrome took place, presenting with drowsiness, poor appetite, and oliguria, after the operation along with multiple organ failure. Awareness of the differential diagnoses of compartment syndrome in such clinical situation is crucial because it may lead to different examination and treatment plan preoperatively.

We here report on a 74-year-old man diagnosed with a pT3cN0 BRAF-mutated and mismatch repair-deficient adenocarcinoma in the colon ascendens and 3 liver metastases. After hemicolectomy, the patient received treatment with the PD-1 inhibitor pembrolizumab. Three weeks later (on day 22), laboratory tests showed leukocytosis and an increase in transaminases; immune checkpoint inhibitor (ICI)-induced hepatitis was suspected and prednisolone therapy was initiated. On day 29, the patient was acutely hospitalized due to dyspnea, somnolence and walking difficulties. Dysarthria, hoarseness, muscle pain and weakness had developed and the dose of prednisolone was increased. Serum levels of lactate dehydrogenase, creatine kinase and myoglobin were increased and ICI-induced myositis was suspected. Antibodies against acetylcholine receptor and titin were present, indicating myasthenia gravis. Eventually, bulbar myopathy developed, including dysarthria and dysphagia, and the patient could no longer attain saturation without oxygen. The patient was transferred to the intensive care unit, intubated and given methylprednisolone, intravenous immunoglobulins and infliximab. The patient developed carbon dioxide retention and died on day 39. Microscopical examination of the intercostal musculature, diaphragm, cervical musculature and tongue showed inflammatory infiltration and fibrosis consistent with a pronounced myositis. In the liver, microscopical examination did not show metastases from colorectal cancer but instead a hepatocellular cancer. The cause of death was determined as respiratory insufficiency due to polymyositis. In conclusion, ICIs may induce myositis combined with neurological immune-related adverse events. In patients developing muscle weakness and pain under ICI therapy, myositis should be suspected.
