Common Hematological Disorders in Children

It is common for primary care physicians to be faced with children with hematological disorders in everyday practice. The article seeks to provide realistic information for the first-contact physician in handling common hematological diseases in children. Practical step-wise approach to understanding and investigating anemia and bleeding disorders is illustrated. Requirement of iron in normal children and management of iron deficiency anemia (IDA) and thalassemia is explained. The gold standard for IDA continues to be ferrous sulphate which has good bioavailability and is inexpensive. There is emerging concept of delayed clamping of umbilical cord at birth, particularly in regions with widespread IDA, to augment iron stores in infancy. Typical case scenarios of children with immune thrombocytopenia (ITP) and hemophilia are provided to facilitate the understanding of management in day to day practice. The vital role of the medical practitioner in shared care of patients with acute lymphoblastic leukemia and febrile neutropenia is emphasized. A risk based treatment algorithm for febrile neutropenia is provided.     

Imaging-based algorithmic approach to gallbladder wall thickening

Gallbladder(GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal. Diffuse wall thickening is a secondary occurrence in both extrinsic and intrinsic pathologies of GB, whereas, focal wall thickening is mostly associated with intrinsic GB pathologies. In the absence of specific clinical features, accurate etiological diagnosis can be challenging. The survival rate in GB carcinoma(GBC) can be improved if it is diagnosed at an early stage, especially when the tumor is confined to the wall. The pattern of wall thickening in GBC is often confused with benign diseases, especially chronic cholecystitis, xanthogranulomatous cholecystitis, and adenomyomatosis. Early recognition and differentiation of these conditions can improve the prognosis. In this minireview, the authors describe the patterns of abnormalities on various imaging modalities(conventional as well as advanced) for the diagnosis of GB wall thickening. This paper also illustrates an algorithmic approach for the etiological diagnosis of GB wall thickening and suggests a formatted reporting for GB wall abnormalities.

Living donor intestinal transplant using a standardized technique: first report from India

Aim

We describe the first living donor intestinal transplant (LDIT) in India and discuss the indications and problems of this complex procedure.

Methods

A 43-year-old male patient required massive bowel resection for gangrene due to thrombosis of the superior mesenteric artery. He was maintained on parenteral nutrition but developed cholestasis and well as repeated catheter related infections with progressive loss of venous access due to thrombosis of central veins. A LDIT was performed using 200?cm of small intestine from the patient's son. The graft was based on the continuation of the superior mesenteric vessels beyond the ileocolic branch. The artery was anastomosed directly to the aorta and the vein to the venacava.

Results

The graft functioned well and he was weaned off parenteral nutrition. However, he later developed complications (wound dehiscence and enterocutaneous fistula) and developed sepsis. He succumbed to sepsis with a functioning graft 6?weeks after the transplant. The donor recovered uneventfully and was discharged on the 4th postoperative day.

Conclusions

LDIT can be life saving in patients with intestinal failure and failure of parenteral nutrition. There is a need to introduce this modality in India. In a setting of scarcity of deceased donor organs the living donor option has advantages.     

Prevalence of hepatitis C virus in a selected geographical area of northern India: a population based survey

Background and Aim

Epidemiological data on hepatitis C virus (HCV) infection from India are scanty. We conducted a population-based seroepidemiologic survey to estimate the prevalence of hepatitis C in Punjab state of northern India.

Methods

A house-to-house survey was conducted in a defined population of 26,273 subjects. Information was gathered according to a predesigned questionnaire with socio-demographic characteristics (age, gender and substance abuse), family history of HCV infection, general health status, associated co-infection, immunization history and potential risk factors for HCV transmission. At the time of clinical evaluation, blood was tested for anti-HCV and those found positive were tested for HCV RNA.

Results

Among 5,258 subjects screened, 272 were found to be anti-HCV positive (prevalence rate of 5.2?%); highest prevalence being noticed in 41?C60?years age group. Anti-HCV positive rate were not different among males and females. Sixty-seven subjects (1.3?%) were found to be HBsAg positive; four of these being co-infected (5.9?%). Various risk factors for acquiring HCV infection identified were history of surgery, dental treatment and unprotected sex. Other associations were strong family history of HCV positivity, alcohol consumption and diabetes mellitus.

Conclusion

Chronic HCV infection is a major health problem in Punjab; it appears to be more common than HBV infection. Exercising safe health care related procedures should be emphasized in our country as main modes of transmission of infection identified were related to these.     

Helicobacter pylori in gallbladder mucosa in patients with gallbladder disease

Background

Helicobacter species have been found to be associated with biliary tract diseases. This prospective study was done to determine the prevalence of H. pylori in the biliary tract of patients suffering from gallbladder disease.

Methods

Forty-nine patients undergoing laparoscopic/open cholecystectomy for benign biliary tract diseases were investigated with urea breath test for H. pylori infection of gastric antrum. Bile and gallbladder tissues were studied for presence of H. pylori by rapid urease test, histopathological examination, culture and PCR analysis. Gallbladder specimens from two patients who underwent Whipple??s operation and from 10 cadavers were studied as controls.

Results

The mean (SD) age of patients was 42.4 (11.1) years. Urea breath test was positive in 17 (34.6%) cases. Rapid urease test was negative in all the cases. There was no evidence of H. pylori infection of gallbladder on histopathological examination using H&;E, Giemsa and Warthin Starry stains. H. pylori DNA were detected in 16 patients (32.6%) and none of the 12 controls by PCR analysis (p?=?0.025). The presence of H. pylori DNA in bile and/or gallbladder was associated with positive urea breath test, (p?H. pylori infection of bile and gallbladder.

Conclusions

Nearly three quarters of patients with positive urea breath test have detectable H. pylori DNA in gallbladder tissue. The significance of these findings needs to be further evaluated.
