1/7. Acute abdomen as an atypical presentation of meningococcal septicaemia.The clinical manifestations and course of meningococcal disease have been well described, but atypical presentations may, if unrecognized, lead to a delay in treatment. We describe here an unusual case of this disease in a 21-y-old woman who presented with an acute rigid abdomen, clinical and laboratory features of sepsis, shock and early DIC with no indication of meningococcal infection. She developed a rapidly spreading purpuric rash, conjunctival haemorrhages, hypotension and tachycardia and a low urine output. Laboratory investigations showed a low platelet count, low haemoglobin and normal WBC. A presumptive diagnosis of meningococcal septicaemia was made and recovery followed treatment with cefotaxime, fluids and inotropes. A fully sensitive Neisseria meningitis Group C, type 2a, subtype NT was isolated from blood cultures, but not from CSF obtained after antibiotic treatment.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
2/7. streptococcus pneumoniae peritonitis postpartum.A peritonitis caused by an ascending infection is a rare complication postpartum. A 37-year-old woman presented with a secondary peritonitis due to streptococcus pneumoniae. The patient had given birth to a healthy boy 4 weeks before and showed no symptoms of a bronchitis on admission. An operation was performed after the patient developed an acute abdomen, showing a diffuse peritonitis. High vaginal swabs and blood cultures taken on admission were positive for S. pneumoniae as well as the specimen taken during the operation. Thus we concluded that this was a case of an ascending infection. After antibiotic therapy with penicillin the patient could be discharged 8 days after the operation.- - - - - - - - - - ranking = 9.5791571299608keywords = pneumoniae (Clic here for more details about this article) |
3/7. A new etiology of acute abdominal emergencies in cirrhotic patient: secondary pneumococcal peritonitis with jejunitis.We report the first case of secondary pneumococcal peritonitis associated with acute jejunitis in a 52-year-old homeless child-Pugh C cirrhotic man without ascitis. The patient was admitted with clinical signs of peritonitis, and jaundice. Morphologic examination was unremarkable. A laparotomy revealed a diffuse peritonitis, and an acute jejunitis with prenecrotic lesion. The lesion was located within the first centimeters of the jejunum, immediately after the duodeno-jejunal angle, extented on 15 cm. A resection of the first 15 cm of the jejunum was performed with duodeno-jejunal side-to-side manual anastomosis. Gram-stain and cultures of blood, peritoneal pus, and jejunal mucosa revealed a penicillin-sensitive streptococcus pneumoniae. Appropriate parenteral antibiotic treatment was initiated (aminopenicillin). The postoperative course was marked by a transient hepatic failure associated with an ascitis controlled by diuretics. The patient was discharged on the 26th day after surgery. This case reports a new etiology of acute abdominal emergencies in cirrhotic patients.- - - - - - - - - - ranking = 1.5965261883268keywords = pneumoniae (Clic here for more details about this article) |
4/7. capnocytophaga canimorsus sepsis presenting as an acute abdomen in an asplenic patient.Acute abdominal symptoms are frequently caused by surgical intra-abdominal problems. However, the differential diagnosis also includes several internal diseases. Overwhelming infections may present with acute abdominal signs, particularly in the immunocompromised host. Asplenic patients are highly susceptible to infections with encapsulated bacteria such as streptococcus pneumoniae, haemophilus influenzae and neisseria meningitidis. Severe infections due to capnocytophaga canimorsus (DF2), are also common in this group. C. canimorsus is a Gram-negative rod, present as a commensal organism in cat and dog saliva. We describe the atypical presentation of a fatal C. canimorsus-sepsis in a 46-year-old man, who underwent traumatic splenectomy two decades earlier.- - - - - - - - - - ranking = 1.5965261883268keywords = pneumoniae (Clic here for more details about this article) |
5/7. A case of group B streptococcal pyomyositis.The group B streptococcus is an opportunistic pathogen that causes a variety of serious infections including bacteremias, puerperal sepsis, and neonatal meningitis. Group B streptococcal infections of muscle are rare. We report here an unusual case of group B streptococcal pyomyositis. pyomyositis arises predominantly from infections caused by staphylococcus aureus and, occasionally, streptococcus pyogenes. Because of the rarity of pyomyositis in temperate climates, the common lack of localizing signs or symptoms, and the frequently negative blood cultures, considerable delay often precedes the diagnosis of pyomyositis; in fact, the infection has been initially misdiagnosed as muscle hematoma, cellulitis, thrombophlebitis, osteomyelitis, or neoplasm. Diagnosis may be greatly aided by radiologic techniques that can demonstrate the sites of muscle enlargement and the presence of fluid collections. The response to antibiotics is usually rapid, but resolution of the infection may require aspiration of deeply situated muscle abscesses. This report describes a diabetic patient with an unusual presentation of pyomyositis that mimicked an acute abdomen.- - - - - - - - - - ranking = 2.7296154178729keywords = streptococcus, meningitis (Clic here for more details about this article) |
6/7. Postsplenectomy capnocytophaga canimorsus sepsis presenting as an acute abdomen.patients with intra-abdominal processes that require prompt surgical intervention, including appendicitis, perforated viscus, ischemic bowel, volvulus, and bowel obstruction, often present with signs and symptoms of an acute abdomen. Several medical problems can mimic an acute abdomen. Overwhelming postsplenectomy infection is a life-threatening condition that can present with acute abdominal symptoms. The incidence of overwhelming postsplenectomy infection ranges from 1% to 25%, and is caused by streptococcus pneumoniae in 50% of cases. capnocytophaga canimorsus, a bacteria commonly found in dog saliva, accounts for less than 1% of cases. Overwhelming postsplenectomy infection has a rapidly deteriorating course that progresses to respiratory and renal failure, cardiovascular collapse, and death. The mortality associated with overwhelming postsplenectomy infection is 60% to 80%. early diagnosis and institution of appropriate antibiotic therapy and supportive care is essential to improve patient outcome. A previously healthy woman who had undergone splenectomy secondary to trauma 11 years earlier presented with symptoms of an acute abdomen. A diagnosis of overwhelming postsplenectomy infection due to C canimorsus was made based on her peripheral blood smear and blood culture findings. Early aggressive care and antibiotic treatment resulted in a successful outcome for this patient with no long-term morbidity. This patient's clinical course demonstrates the importance of early diagnosis and treatment of overwhelming postsplenectomy infection.- - - - - - - - - - ranking = 1.5965261883268keywords = pneumoniae (Clic here for more details about this article) |
7/7. Streptococcal pyomyositis: case report and review.pyomyositis is most often associated with staphylococcus aureus infections after trauma. We describe an unusual presentation of pyomyositis of the chest wall secondary to group A betahemolytic streptococcus infection in a 15-month-old child with acute abdominal symptoms. In addition, the patient had no history or evidence of trauma to the affected area. pyomyositis presenting in this manner secondary to group A beta-hemolytic streptococcus infection in the absence of a primary varicella infection has not been previously reported.- - - - - - - - - - ranking = 3.4592308357458keywords = streptococcus (Clic here for more details about this article) |
