ABSTRACT

Duodenal ulcer perforations have been known since 1600 AD. It is a common surgical emergency and every surgeon will encounter it. The perforation size of >2 cm has been used as the criteria for defining Giant duodenal ulcers. The management of giant duodenal perforations in hemodynamically unstable patient with comorbid condition is taxing because of high incidence of the postoperative leak and mortality. We have used the simple technique of Triple Tube Ostomy after the primary closure of the defect with encouraging results. It is a retrospective study done at the J. N medical college AMU Aligarh from May 2005 to May 2015. Hemodynamically unstable patients who have presented to the emergency with preoperative diagnoses of giant duodenal ulcer perforation and had undergone triple tube ostomy with primary repair of the perforation were included in the study. There were 34 patients of giant duodenal perforation who presented in shock. All of them underwent triple-tube-ostomy after primary repair of the duodenum. Thirty-two patients recovered with two mortalities (5.8 %). Several definite surgical techniques have been described for the management of giant duodenal ulcer perforation but they are complex, have very high morbidity and mortality rate and require an expert surgeon. A close retrospective scrutiny of the patients suggests that simple triple-tube-ostomy technique which is based on the principle of damage control surgery has good postoperative results Therefore, we recommend it as the procedure of choice in these patients.

ABSTRACT

Cancer-associated fibroblasts (CAFs), the most abundant and probably the most active cellular component of breast cancer-associated stroma, promote carcinogenesis through paracrine effects; however, the molecular basis remains elusive. We have shown here that p16(INK4A) expression is reduced in 83% CAFs as compared with their normal adjacent counterparts cancer-free tissues isolated from the same patients. This decrease is mainly due to AUF1-dependent higher turnover of the CDKN2A mRNA in CAFs. Importantly, p16(INK4A) downregulation using specific siRNA activated breast fibroblasts and increased the expression/secretion levels of stromal cell-derived factor 1 (SDF-1) and matrix metalloproteinase (MMP)-2. Consequently, media conditioned with these cells stimulated the proliferation of epithelial cells. Furthermore, the migration/invasion of breast cancer cells was also enhanced in an SDF-1-dependent manner. This effect was mediated through inducing an epithelial-mesenchymal transition state. By contrast, increase in p16(INK4A) level through ectopic expression or AUF1 downregulation, reduced the secreted levels of SDF-1 and MMP-2 and suppressed the pro-carcinogenic effects of CAFs. In addition, p16(INK4A)-defective fibroblasts accelerated breast tumor xenograft formation and growth rate in mice. Importantly, tumors formed in the presence of p16(INK4A)-defective fibroblasts exhibited higher levels of active Akt, Cox-2, MMP-2 and MMP-9, showing their greater aggressiveness as compared with xenografts formed in the presence of p16(INK4A)-proficient fibroblasts. These results provide the first indication that p16(INK4A) downregulation in breast stromal fibroblasts is an important step toward their activation.

ABSTRACT

Xanthomonas oryzae pv. oryzae, the causal organism of bacterial blight of rice which produces leaf blight as well as kresek (wilt) symptoms in plants were tested for indole, auxin production in culture supplemented with L-tryptophan. On the basis of indoleacetic acid (IAA) production the isolates were grouped into IAA-positive and IAA-negative. Out of 17 isolates, 11 were IAA-positive while 6 were IAA-negative. The isolates metabolized tryptophan through two different routes and the isolates vary in the pathway of tryptophan utilization. The IAA-positive isolates converted tryptophan to IAA as the end product, whereas the IAA-negative isolates formed anthranilate as an intermediate metabolite and finally produced pyrocatechol via the kynurenine pathway. Quantification of tryptophan metabolism revealed that the maximum production of IAA and pyrocatechol in culture occurred during 2-d incubation at 30 +/- 2 degrees C.

ABSTRACT

A prospective study on audiometric changes following spinal anaesthesia with different gauge spinal needles was carried out in 125 patients; the patients were randomly divided into five groups according to gauge of needles used i.e., 20, 22, 23, 24 and 25 with twenty five patients in each group. Twelve percent and 8% decrease in audiometric values were recorded on first postoperative day at 250-500 Hz frequencies with 20 and 22 gauge needles respectively and these changes were highly significant (P < 0.001); these audiometric alterations returned to within normal limits by the 5th postoperative day. Eight percent decrease in audiometric values were observed on first postoperative day at 250-500 Hz frequencies with 23 gauge needle which was also statistically significant (P < 0.05); these changes returned to near normal limits by the 5th postoperative day. There was no significant decrease in the audiometric values following spinal anaesthesia with 24 and 25 gauge needles.

ABSTRACT

Forty-seven patients with oesophageal carcinoma were managed in 6 years' time. Average duration of illness was 5.5 months. History of chronic smoking and/or tobacco chewing was present in 80.85% of patients. Carcinoma included squamous cell variety (80.85%) and adenocarcinoma (19.15%). Thirty-one patients were in stage III while 16 patients were in stage II. Surgery included oesophagogastrectomy/oesophagogastrostomy (16 patients), feeding gastrostomy (11 patients), Mousseau-Barbin tube insertion (10 patients), only 10 patients were subjected to palliative radiotherapy. All patients after palliative treatment died within one year whereas 3-year and 5-year survivals after oesophagogastrectomy/oesophagogastrostomy were 68.75% and 31.25% respectively. Local lymph node metastasis adversely affected the 5-year survival rate.

ABSTRACT

During last six years, 2250 patients were treated in Cardiothoracic Unit for thoracic complications of pulmonary tuberculosis. During isoniazid/streptomycin/ethambutol treatment, 2 patients out of 710 (0.28%) developed hepatitis. During isoniazid/rifampicin/ethambutol therapy, 18 patients out of 1540 (1.17%) suffered from jaundice; all these patients were above 30 years of age, and many had gross anemia (Hb less than 9 gm%), hypoalbuminemia (less than 3 gm%) and radiologically far-advanced disease in comparison to those who did not develop jaundice (p less than 0.05). Jaundice subsided completely after discontinuation of isoniazid and/or rifampicin which were re-instituted successfully after recovery without recurrence of hepatitis. It is suggested that the development of hepatitis does not warrant total withdrawal of these two highly effective bactericidal drugs but they should be tried again cautiously after recovery from jaundice.

ABSTRACT

Thirty normotensive patients (ASA class I) and 30 treated hypertensives without any cardiac problem (ASA class II) were subjected to elective cholecystectomy under general anaesthesia. Patients' age ranged from 25-50 yr, and male:female ratio was 1:11. There were significant increases in heart rate and mean arterial pressure in both the groups (P less than 0.05) during surgical manipulations for removal of the diseased gall bladders. The alterations in the treated hypertensive patients were not only much more than in the normotensives, but also were associated with tachyarrhythmias in 33.33 per cent of hypertensive patients. All changes returned to the pre-induction level at the end of the surgery. Mediation through fifth thoracic spinal segment, a common source of sympathetic supply to heart and gallbladder, explained the observed cholecystocardiac link. Anaesthetists therefore need to be vigilant during cholecystectomies.

ABSTRACT

A total of 100 cases of flail chest were studied to find out the efficiency of the anti-lung contusion regimen containing a diuretic, a steroid and an enzyme preparation for some 10 days, along with pad and strapping. There were 80 males and 20 females. Majority (71%) of patients were between 16 and 45 years. Road side accident was the commonest cause, present in 65% cases followed by bull horn injuries (25%), fall from a height (8%) and gun shot injuries to chest (2%). Associated intrathoracic and extrathoracic injuries were recorded in 45% and 30% cases respectively and they were treated according to their merits. There were 11 deaths with an overall success rate of 89%.

ABSTRACT

Changes in serum calcium after diethyl-ether anaesthesia given for various routine surgical operations, were studied in 30 patients. Mean (+/- SD) concentration (mg%) of serum calcium before induction of anaesthesia was 10.37 +/- 0.77. Serum calcium decreased by 0.05 per cent after 10 min of induction and by 3.33 per cent at the end of anaesthesia which was highly significant (P less than 0.001). There was a correlation (r = 0.63; P less than 0.01) between decline in serum calcium and duration of ether anaesthesia. Serum calcium returned to near normal levels after 24 h of ether anaesthesia. In view of the fall in serum calcium, it is emphasized that ether should be either avoided in patients with known or suspected hypocalcaemia or be used for as short a time as possible with due precaution and calcium supplementation.
