Cholangitis Due to Candidiasis of the Extra-Hepatic Biliary Tract
A case of isolated candidal fungal balls in the
common bile duct causing obstructive jaundice and
cholangitis is described. There were no predisposing
factors. The fungal balls were removed from the
common bile duct and a transduodenal sphincteroplasty
was performed. Microscopic analysis yielded
colonies of candida. Postoperative period was uneventful.
At follow-up no evidence of candida
infection was evident. He is now 3 years post-surgery
and is well
Small intestinal deficit in pellagra
Twenty-four persons with pellagra were the subjects of absorption testing. Fourteen (58.3%) showed evidence of defective absorption of two or three absorption tests and eight showed (33.3%) abnormality of only one of the tests of absorption. Only two cases (8.3%) were found to be having completely normal absorptive status of the small bowel. Six of these fourteen (42.8%) cases recovered completely or partially on treatment with nicotinic acid. The etiopathogenesis of malabsorption in pellagra is discussed. Patients of both primary as well as secondary pellagra showed similar derangement of small intestinal functions
Role of Endoscopic Retrograde Cholangiography and Nasobiliary Drainage in the Management of Postoperative Biliary Leak
In order to assess the role of endoscopic retrograde cholangiography in evaluating the patients with post-operative biliary leak and of endoscopic nasobiliary drainage in its management, 36 patients with biliary leak seen over a period of 9 years were studied. Thirty-two had biliary leak following cholecystectomy, 3 following repair of liver trauma and 1 following choledochoduodenostomy. Patients presented at an interval of 4 days to 210 days (mean Β± SEM, 32.4 Β± 6.7 days) following laparotomy. Hyperbilirubinemia was noticed in only 13 patients (36.1%), while abdominal ultrasonogram showed ascites or biloma in 24 (66.7%). Endoscopic retrograde cholangiography showed the leak to involve the common bile duct in 55.6%, cystic duct in 33.3% and intrahepatic biliary radicles in 8.3%. Associated lesions included bile duct obstruction due to stricture or accidental ligature in 20%, bile duct stone in 20% and liver abscess in 2.8%
Chikungunya Infection in India: Results of a Prospective Hospital Based Multi-Centric Study
Chikungunya (CHIKV) has recently seen a re-emergence in India with high morbidity. However, the epidemiology and disease burden remain largely undetermined. A prospective multi-centric study was conducted to evaluate clinical, epidemiological and virological features of chikugunya infection in patients with acute febrile illness from various geographical regions of India.A total of 540 patients with fever of up to 7days duration were enrolled at Karnataka Institute of Medical Sciences (KIMS), Karnataka (South); Sawai Man Singh Medical College (SMS) Rajasthan (West), and All India Institute of Medical Sciences (AIIMS) New Delhi (North) from June 2008 to May 2009. Serum specimens were screened for chikungunya infection concurrently through RT-PCR and serology (IgM). Phylogenetic analysis was performed using Bioedit and Mega2 programs. Chikungunya infection was detected in 25.37% patients by RT-PCR and/or IgM-ELISA. Highest cases were detected in south (49.36%) followed by west (16.28%) and north (0.56%) India. A difference in proportion of positives by RT-PCR/ELISA with regard to duration of fever was observed (p<0.05). Rashes, joint pain/swelling, abdominal pain and vomiting was frequently observed among chikungunya confirmed cases (p<0.05). Adults were affected more than children. Anti-CHIK antibodies (IgM) were detected for more than 60days of fever onset. Phylogenetic analysis based on E1 gene from KIMS patients (nβ=β15) revealed βΌ99% homology clustering with Central/East African genotype. An amino acid change from lysine to glutamine at position 132 of E1 gene was frequently observed among strains infecting children.The study documented re-emergence of chikungunya in high frequencies and severe morbidity in south and west India but rare in north. The study emphasizes the need for continuous surveillance for disease burden using multiple diagnostic tests and also warrants the need for an appropriate molecular diagnostic for early detection of chikungunya virus
Primary gastric tuberculosis β report of 5 cases
BACKGROUND: Gastric tuberculosis is rare, and usually associated with pulmonary tuberculosis or an immunodeficient state. Here, we report five cases of gastric tuberculosis in immunocompetent patients without evidence of pulmonary involvement. CASE PRESENTATION: Three patients presented with gastric outlet obstruction that required surgery to relieve the obstruction as well as to confirm the diagnosis. The remaining two had involvement of gastroesophageal junction. All of them responded well to standard antitubercular treatment. CONCLUSION: Though gastric tuberculosis is rare, it should be considered a possibility when patients present with gastric outlet obstruction or with endoscopic evidence of diffuse chronic inflammatory activity, particularly in areas endemic for tuberculosis
Clinical outcomes in typhoid fever: adverse impact of infection with nalidixic acid-resistant Salmonella typhi
BACKGROUND: Widespread use of fluoroquinolones has resulted in emergence of Salmonella typhi strains with decreased susceptibility to fluoroquinolones. These strains are identifiable by their nalidixic acid-resistance. We studied the impact of infection with nalidixic acid-resistant S. typhi (NARST) on clinical outcomes in patients with bacteriologically-confirmed typhoid fever. METHODS: Clinical and laboratory features, fever clearance time and complications were prospectively studied in patients with blood culture-proven typhoid fever, treated at a tertiary care hospital in north India, during the period from November 2001 to October 2003. Susceptibility to amoxycillin, co-trimoxazole, chloramphenicol, ciprofloxacin and ceftriaxone were tested by disc diffusion method. Minimum inhibitory concentrations (MIC) of ciprofloxacin and ceftriaxone were determined by E-test method. RESULTS: During a two-year period, 60 patients (age [mean Β± SD]: 15 Β± 9 years; males: 40 [67%]) were studied. All isolates were sensitive to ciprofloxacin and ceftriaxone by disc diffusion and MIC breakpoints. However, 11 patients had clinical failure of fluoroquinolone therapy. Infections with NARST isolates (47 [78%]) were significantly associated with longer duration of fever at presentation (median [IQR] 10 [7-15] vs. 4 [3-6] days; P = 0.000), higher frequency of hepatomegaly (57% vs. 15%; P = 0.021), higher levels of aspartate aminotransferase (121 [66β235] vs. 73 [44β119] IU/L; P = 0.033), and increased MIC of ciprofloxacin (0.37 Β± 0.21 vs. 0.17 Β± 0.14 ΞΌg/mL; P = 0.005), as compared to infections with nalidixic acid-susceptible isolates. All 11 patients with complications were infected with NARST isolates. Total duration of illness was significantly longer in patients who developed complications than in patients who did not (22 [14.8β32] vs. 12 [9.3β20.3] days; P = 0.011). Duration of prior antibiotic intake had a strong positive correlation with the duration of fever at presentation (r = 0.61; P = 0.000) as well as the total duration of illness (r = 0.53; P = 0.000). CONCLUSION: Typhoid fever caused by NARST infection is associated with poor clinical outcomes, probably due to delay in initiating appropriate antibiotic therapy. Fluoroquinolone breakpoints for S. typhi need to be redefined and fluoroquinolones should no longer be used as first-line therapy, if the prevalence of NARST is high
