Pantoprazole sodium, a substituted benzimidazole derivative, is an irreversible proton pump inhibitor which is primarily used for the treatment of duodenal ulcers, gastric ulcers, and gastroesophageal reflux disease (GERD). The monographs of European Pharmacopoeia (Ph. Eur.) and United States Pharmaco-poeia (USP) specify six impurities, viz.; impurities A, B, C, D, E and F, respectively for its active phar-maceutical ingredient (API). The identification and synthesis of all impurities except impurity E are well described in the literature; however, there is no report related to impurity E. The prospects to the for-mation and controlling of impurity E up to ≤0.03％ in the synthesis of pantoprazole sodium sesquihydrate (PAN) were discussed in detail for the first time. The present work described the journey towards the successful development of an optimal preparation procedure of dimer impurity E. The most plausible mechanism involved in the formation of impurity E has been proposed.

We report an important observation that the surface conductivity of antibody layer immobilized on polylysine-coated glass substrate decreases upon the formation of complex with their specific antigens. This change in conductivity has been observed for both monoclonal and polyclonal antibodies. The conductance of monoclonal mouse IgG immobilized on polylysine-coated glass substrate changed from 1.02x10(-8) ohm(-1) to 1.41x10(-11) ohm(-1) at 10 V when complex is formed due to the specific biomolecular interactions with rabbit anti-mouse IgG F(ab')(2). Similar behavior was observed when the same set up was tested in two clinical assays: (1) anti-Leishmania antigen polyclonal antibodies taken from Kala Azar positive patient serum interacting with Leishmania promastigote antigen, and (2) anti-p21 polyclonal antibodies interacting with p21 antigen. The proposed concept can represent a new immunodiagnostic technique and may have wide ranging applications in biosensors and nanobiotechnology too.

Serous ovarian cancer is the most common malignant ovarian tumour. Traditional management consists of surgical resection with postoperative chemotherapy. Currently neoadjuvant chemotherapy is offered to patients with advanced stage disease. The present study aims to analyse the histomorphological alterations in serous ovarian cancer following neoadjuvant chemotherapy. Correlation of these morphological alterations with survival is also presented here. Serous ovarian cancers from 100 advanced stage cases were included; 50 were treated with pre-surgery chemotherapy. Semi-quantitative scoring was used to grade the alterations in tumour morphology. Survival data was correlated with the final morphological score. Tumour morphology was significantly different in cases treated with neoadjuvant chemotherapy (CT group) as compared to cases with upfront surgery. The CT group cases showed more fibrosis, calcification, and infiltration by lymphocytes, plasma cells, foamy and hemosiderin-laden macrophages. The residual tumour cells had degenerative cytoplasmic changes with nuclear atypia. Patients with significant morphological response had a longer median survival, although it did not attain statistical significance in the current study. With the increasing use of neoadjuvant chemotherapy in management, the pathologist needs to be aware of the altered morphological appearance of tumour. Further studies are required to establish a grading system to assess the tissue response which can be helpful in predicting the overall therapeutic outcome and the prognosis of patients.

This case report presents a 25-year-old female patient with anterior dislocation of right shoulder secondary to seizures as a complication of eclampsia. This is an unusual mechanism of injury, but similar to other uncontrolled muscular contractions caused by electroconvulsive therapy, etc. To the best of our knowledge only one such case has been reported in the English literature. Closed reduction under general anaesthesia was successfully achieved. High suspicion in patients complaining of pain over shoulder joint is necessary for early diagnosis of this condition.

Formation of an aneurysm in the sinus of Valsalva of the aortic root is usually due to an area of congenital weakness in its wall. This aneurysm may progressively dilate and rupture into any of the cardiac chambers or into the pericardial cavity. Though this is conventionally treated by surgery, interventional therapy using various closure devices is becoming more common. Embolization of these closure devices may occur. We report a case of embolization of such a device into the left pulmonary artery which during surgical retrieval, unmasked the hidden ventricular septal defect (VSD). Therefore one has to be cautious while making a diagnosis of rupture of the sinus of Valsalva of right coronary sinus without VSD.

Subacute posttraumatic ascending myelopathy is a rare disorder, unrelated to syrinx formation or mechanical instability, which may gradually emerge within the first 1-2 weeks after a spinal cord injury and may lead to diagnostic and prognostic dilemmas. We present a case of 24-year-old female with unstable wedge compression fracture of L1 vertebrae with signal changes in the upper lumbar cord causing complete paraplegia below D9 with bladder and bowel involvement. In the subsequent week, she developed a delayed progressively increasing neurological deficit with cord signal abnormality on MRI extending cephalad from the injury site to the upper dorsal cord. The patient had no initial clinical improvement initially but showed a delayed recovery over months.

INTRODUCTIONConcerns about the life shortening effect of opioids is a well known fact in the medical world when considering administration of these drugs for symptom alleviation at end of life. This study described the patterns of opioid use among cancer patients referred to a hospital-based specialist palliative care service for symptom management. This study also examined whether opioid use among terminally ill cancer patients during the last 2 days of life had any influence on survival.

MATERIALS AND METHODSA retrospective review of case notes of patients who were diagnosed with terminal cancer and had passed away in a 95-bedded oncology ward between September 2006 and September 2007 was conducted. Data were collected on patients' characteristics and patterns of opioid use including opioid doses and dose changes at 48 hours and 24 hours before death.

RESULTSThere were 238 patients who received specialist palliative care, of whom 132 (55.5%) were females. At 48 hours and 24 hours before death, 184 (77.3%) patients and 187 (78.6%) patients had received opioids, respectively. The median daily doses at 48 hours and 24 hours were 48 mg and 57 mg oral morphine equivalent doses (OME), respectively. Indications for opioid use were pain (41.1%), dyspnoea, (29.1%) and both dyspnoea and pain (30.8%). In the fi nal 24 hours, 22.3% patients had a reduction in their mean opioid dose while 22.7% required an increase in their mean opioid dose. Increased age was associated with decreasing opioid doses (P = 0.003). Patients with spinal metastases required higher doses of opioids (P = 0.03) while those with lung metastases required lower doses (P = 0.011). Survival analysis using Kaplan-Meier survival curve revealed no significant survival difference between those who were on opioids and those who were not. Log rank test (Mantel-Cox) (P = 0.69).

CONCLUSIONOur results showed that opioids are safe medications for symptom alleviation in terminally ill cancer patients during the last days of life and have no deleterious influence on survival.

Purpose: Intensity-modulated radiotherapy (IMRT) provides higher dose to target volumes and limits the dose to normal tissues. IMRT may be applied using either simultaneous integrated boost (SIB-IMRT) or sequential boost (SEQ-IMRT) technique. The objectives of this study were to compare acute toxicity and objective response rates between SIB-IMRT and SEQ-IMRT in patients with locally advanced head and neck cancer. Materials and Methods: Total 110 patients with locally advanced carcinoma of oropharynx, hypopharynx, and larynx were randomized equally into the two arms (SIB-IMRT vs. SEQ-IMRT). Patients in SIB-IMRT arm received dose of 66 Gy in 30 fractions, 5 days a week, over 6 weeks. SEQ-IMRT arm’s patients received 70 Gy in 35 fractions over 7 weeks. Weekly concurrent cisplatin chemotherapy was given in both arms. Patients were assessed for acute toxicities during the treatment and for objective response at 3 months after the radiotherapy. Results: Grade 3 dysphagia was significantly more with SIB-IMRT compared to SEQ-IMRT (72% vs. 41.2%; p = 0.006) but other toxicities including mucositis, dermatitis, xerostomia, weight-loss, incidence of nasogastric tube intubation and hospitalization for supportive management were similar in both the arms. Patients in SIB-IMRT arm showed better treatment-compliance and had significantly less treatment-interruption compared to SEQ-IMRT arm (p = 0.028). Objective response rates were similar in both the arms (p = 0.783). Conclusion Concurrent chemoradiation with SIB-IMRT for locally advanced head and neck cancer is well-tolerated and results in better treatment-compliance, similar objective response rates, comparable incidence of mucositis and higher incidence of grade 3 dysphagia compared to SEQ-IMRT.
