A SEARCH FOR UNHAPPY ABDOMEN: PREVALENCE OF IRRITABLE BOWEL SYNDROME IN GENERAL POPULATION

The irritable bowel syndrome is the commonest gastrointestinal disorder seen in practice but its exact prevalence in India is not known. This study was carried out to determine the prevalence of symptoms compatible with this diagnosis in general population. A cross sectional random sample survey was conducted in various strata of urban population in Wanoworie area of Pune. Survey utilized personal interviews based on a questionnaire. Symptoms were evaluated as per Manning criteria and the diagnosis of irritable bowel syndrome was defined by Kruis diagnostic index. Of the 1010 subjects interviewed, 370 (37%) reported more than 6 episodes of abdominal pain in previous 6 months, with 333 reporting symptoms consistent with the the diagnosis of irritable bowel syndrome. At least one of the Manning''s symptoms was present in 307 out of 370 subjects (83%). The male female ratio was 5.3:1. Among males, 288 (35%) and among females 82 (53.2%) persons had at least some degree of abdominal discomfort. Other common symptoms were: excessive passage of wind (42.2%), irregular bowel habits (33%), excessive belching (30.8%), constipation (27.5) and feeling of incomplete evacuation(28.1%). About one third of the symptomatic subjects (134 or 36.2%) had seen a doctor or wanted to be seen by a specialist. Overall prevalence of the symptoms consistent with irritable bowel syndrome thus, is 33 per cent though only about a third of these may possibly consult a doctor. Follow up of all these patients for a mean duration of 8.3 months showed that no case of organic disease was picked up either by the scoring system or by the gastroenterologist. Symptoms consistent with the diagnosis of irritable bowel syndrome are see in almost one third of the study population residing in Wanoworie area of Pune.KEYWORDS: Irritable bowel syndrome, Kruis diagnostic index, Manning''s symptoms     

Hormone Receptors,Her-2/Neu and Chromosomal Aberrations in Breast Cancer

Background

There is a great deal of disparity in the incidence of breast cancer in rural and urban India on one hand and between India and Western population on the other.

Methods

We analysed steroid receptor status in cases of breast cancer in a small sample of patients in armed forces. Infiltrating duct carcinomas of breast recorded histologically in mastectomy specimens in last two years were accessioned in the present study with reference to patient and tumour characteristics.

Result

In contrast to the higher rates reported in western literature, only 33 % of the tumours expressed estrogen receptors (ER) and progesterone receptors (PR), of which 24% were ER positive and 30% PR positive. Negative steroid receptor status did not correlate with presence or absence of metastatic nodes, however it was predominant amongst the high grade infiltrating duct carcinomas in this study. Necrosis and lymphovascular invasion demonstrated an inverse relationship with the ER/ PR reactivity. 70% of the node positive cases expressed Her –2/ Neu, reflecting a higher immunoreactivity in this subset of patients. Aneusomy for chromosomes 1, 11 and 17 was common in node positive cases.

Conclusion

Evaluation of chromosomal aberrations by Fluorescent In Situ Hybridization (FISH) technique correlates well with traditional histological parameters.Key Words: Breast carcinoma, Hormone receptors, Her –2/ Neu     

EARLY DIAGNOSIS IN POST RENAL TRANSPLANT OPPORTUNISTIC INFECTIONS: A FRESH LOOK

A total of 86 renal transplant patients who were transplanted with live related donor (LRD) and live unrelated donor (LURD) kidneys were studied for opportunistic infections. Immune diagnosis of Toxoplasma, Cytomegalovirus (CMV), Herpes-simplex virus type II (HSV-2), Aspergillosis and Tuberculosis was carried out in these patients along with sputum examination, CSF studies and biopsy of lymphnode and other tissues in few cases. A high degree of Toxoplasma, CMV & HSV-2 positivity was seen in transplanted patients. However sensitivity of serological diagnosis of tuberculos was found to be low with standard criteria, which increased significantly when modified criteria were used. It is concluded that regular immunological monitoring should be carried out in transplanted patients so as to reach an early diagnosis and management of opportunistic infections.KEY WORDS: Immune diagnosis, Opportunistic infections, Transplantation     

Blood loss and contributing factors in femoral fracture surgery

Background

Substantial blood losses frequently accompany orthopedic procedures.

Methods

We prospectively noted peri-operative hemoglobin changes in 93 patients undergoing surgery for femoral fracture with an aim of establishing blood loss and related factors.

Results

The mean total blood loss assessed 72 hours after the surgical procedure was 3.31 (SD 1.56) units of whole blood. A multiple regression analysis revealed diathermy use and a simple fracture pattern as significant factors in reducing blood loss (p<0.01).

Conclusions

Open intramedullary fixation of femur fractures leads to considerable peri-operative blood loss. This is can be reduced by use of diathermy during surgery.     

USEFULNESS OF EVALUATION OF ANTIMEASLES ANTIBODIES IN PRETERM BABIES

As per WHO recommendations, measles vaccine is administered at the age of 9 months which is based on studies demonstrating seroconversion (from positive to negative) at this age. However this contention may not hold good in preterm babies since they may have lower initial levels of passively transferred IgG antimeasles antibodies of maternal origin. To explore this possibility, 50 preterm babies (gestational age less than 37 weeks) were studied for antimeasles antibodies. Serum samples were collected at birth and then at 3 months and 5 months of age in all the cases. Antimeasles antibody assay was done in all the serum samples using ELISA kits. At birth 32% of infants were positive for antimeasles antibodies whereas 60% were weakly positive and 8% were negative. At 3 months of age 50% were sero negative, 2% positive and 40% weakly positive. The sero negativity was found to be 98% at 5 months with only 2% remaining positive. Since seroconversion is seen to occur in this vast majority of preterm infants at the age of 5 months, antimeasles vaccine should be administered at this age to this subset of more vulnerable babies.KEY WORDS: Antimeasles antibodies, Preterm babies, Seroconversion     

Imaging in bronchopulmonary sequestration

Bronchopulmonary sequestration is an uncommon pulmonary disorder characterized by an area of non‐functioning abnormal lung tissue, which receives its blood supply from a systemic artery and characteristically has no connection with the tracheobronchial tree. The abnormal lung tissue is located within the visceral pleura of a pulmonary lobe in the intralobar variety, whereas the extralobar form has its own visceral pleura. The venous drainage of the extralobar type is usually into the systemic veins, whereas the intralobar type drains into the pulmonary veins. Radiological imaging plays a vital role in establishing the diagnosis, and even more importantly, in providing to the clinician a vascular roadmap essential for surgical planning. We present here a review of bronchopulmonary sequestration and also discuss the role of various imaging methods in the early diagnosis and management of these cases.
