Clinical Predictors of Fulminant Colitis in Patients with Clostridium difficile Infection

Background/Aim:

Clostridium difficile infection (CDI) can affect up to 8% of hospitalized patients. Twenty-five percent CDI patients may develop C. difficile associated diarrhea (CDAD) and 1–3% may progress to fulminant C. difficile colitis (FCDC). Once developed, FCDC has higher rates of complications and mortality.

Patients and Methods:

A 10-year retrospective review of FCDC patients who underwent colectomy was performed and compared with randomly selected age- and sex-matched non-fulminant CDAD patients at our institution. FCDC (n=18) and CDAD (n=49) groups were defined clinically, radiologically, and pathologically. Univariate analysis was performed using Chi-square and Student''s t test followed by multivariate logistic regression to compute independent predictors.

Results:

FCDC patients were significantly older (77 ± 13 years), presented with triad of abdominal pain (89%), diarrhea (72%), and distention (39%); 28% had prior CDI and had greater hemodynamic instability. In contrast, CDAD patients were comparatively younger (65 ± 20 years), presented with only 1 or 2 of these 3 symptoms and only 5% had prior CDI. No significant difference was noted between the 2 groups in terms of comorbid conditions, use of antibiotics, or proton pump inhibitor. Leukocytosis was significantly higher in FCDC patients (18.6 ± 15.8/mm³ vs 10.7 ± 5.2/mm³; P=0.04) and further increased until the point of surgery. Use of antiperistaltic medications was higher in FCDC than CDAD group (56% vs 22%; P=0.01).

Conclusions:

Our data suggest several clinical and laboratory features in CDI patients, which may be indicative of FCDC. These include old age (>70 years), prior CDI, clinical triad of increasing abdominal pain, distention and diarrhea, profound leukocytosis (>18,000/mm³), hemodynamic instability, and use of antiperistaltic medications.     

Laparoscopic Heller Myotomy for Achalasia Cardia—Initial Experience in a Teaching Institute

Laparoscopic Heller cardiomyotomy and Dor fundoplication is the surgical procedure of choice for esophageal achalasia. The aim of our study was to investigate the clinical outcome and safety of laparoscopic Heller–Dor procedure performed by using Hook electrocautery and as a teaching module for advanced laparoscopic surgery. Between January 2005 and December 2010, 25 consecutive patients with achalasia underwent laparoscopic Heller–Dor operation by a single surgeon. All the patients received upper gastrointestinal series (barium swallow), esophagogastroscopy, and esophageal manometry to exclude esophageal carcinoma and to confirm the diagnosis. All the patients were operated by laparoscopic modified Heller myotomy with Dor fundoplication by using hook electrocautery. Among 25 operated patients, 14 were male and 11 were female with a median age of 43 years (range 18–72 years). The mean operative time was 93.3 min (range 50–50 min), the mean operative blood loss was 90 ml (range 40–200 ml), the median time to oral feeding was 2 days (2–4 days), and the median hospital stay was 4 days (4–7 days). There was no conversion to open surgery. Intraoperative mucosal perforation was encountered in three patients and was repaired in all of them by laparoscopic suture. All the patients had an uneventful recovery without postoperative complication and had excellent clinical response (96 %) during follow-up. Laparoscopic Heller–Dor operation using hook electrocautery is safe, inexpensive, and effective treatment for achalasia which is useful for teaching and training surgical residents in advanced laparoscopic surgery.     

Results of non-vascularised fibular grafting in gap non-union of long bones in paediatric age group

BackgroundBone defect has always been a challenge to treat for the orthopaedic surgeon. Fibular grafting is a popular method for bridging the gap in bone defects created by tumour excision, trauma or bone loss as sequelae to infection. Fibula is a popular substitute for this method because of its easy accessibility and minimal donor site morbidity. The present study is aimed at finding the results in paediatric population.Material and methods20 patients with bone defect (19 as a result of chronic osteomyelitis and one as a result of excision of a tumour) were included in the current study. The age of the patients ranged from one year to 12 years. The fibular graft was applied after freshening of bone end and fixed with K wire or plating and cancellous bone graft was also applied at both ends. The limb was immobilized in plaster till union of fibula at both ends.ResultsThe average gap was 8 cm (range 6–12 cm). Out of the twenty cases nine involved the humerus, seven in the tibia, two in radius and one each in femur and ulna. Union was achieved at both ends in 80% of the patients after the first surgery. Three out of six patients with K wire as fixation device failed and one out of fourteen patients with plate as fixation device ended in non-union. Union was achieved in these patients after revision surgery. One patient had stress fracture at distal end of the plate after weight bearing. Union occurred in this patient after plaster immobilization. Range of motion at distal and proximal joint was comparable to normal side. Superficial infection was seen in two patients and they responded to antibiotics.ConclusionNon-vascularised fibular grafting is a good option for bone defects in paediatric population provide adequate fixation and immobilization has been done.Level of evidenceLevel IV (Therapeutic).     

Managing scaphoid fractures. How we do it?

The scaphoid is the common carpal bone to be fractured. Proper clinical and radiological evaluation is required to establish it's diagnosis. The management of acute fractures includes conservative treatment with cast in minimally displaced to open reduction and internal fixation in case of displaced ones. The established nonunion requires open reduction, bone grafting and internal fixation.
