Strategic administration of antioxidant multiminerals and vitamins to transitional buffaloes augments antioxidant and udder defense mechanisms in early lactation.

The aim of the study was to examine the effects of repeated administrations of antioxidant multiminerals and vitamins in transition buffaloes on udder defense mechanism, antioxidant activity and occurrence of intramammary infection (IMI) in early lactation period. Forty clinically healthy pregnant buffaloes were enrolled 45 days before expected date of calving and randomly allocated into five different supplementation groups (n = 8): only basal ration (control), vitamin E and selenium (VES), multiminerals (MM), ascorbic acid (AA) and chromium (Cr) picolinate in basal diet. The udder defense mechanism was monitored by measuring phagocytic activity (PA), myeloperoxidase (MPO) and nitric oxide (NO) productions in milk leukocytes, antioxidant activity was evaluated by measuring total antioxidant capacity (TAC) in plasma and occurrence of IMI was assessed by milk cytology, bacterial count in milk and visible clinical signs of udder until day 28 post-calving. The results showed that the VES and MM supplementations exhibited significantly higher PA, MPO and NO productions of milk leukocytes till first week of lactation whereas, elevated mean TAC in plasma was maintained from day -7 to 1 of calving in MM supplementation group as compared to control group. Statistically, no significant difference in occurrences of subclinical or clinical IMI was noted across the groups until four weeks of lactation. Taken together, it is concluded that repeated administrations of VES and MM to transition buffaloes could be an effective strategy to maintain good udder health by augmenting milk leukocyte functions and antioxidant status and preventing incidence of IMI in early lactation.

Clinical Outcome in Intra Articular Distal Humerus Fractures in Adults Treated with Different Hardware in a Tertiary Level Hospital of Bangladesh.

In adults, distal humerus fractures are infrequent and frequently intra-articular. Customarily encompass both medial and lateral columns. Operative management gives constructive outcomes. The aim of this study was to evaluate clinical outcome in intra articular distal humerus fractures in adults treated by different hardware. This prospective study consists of 20 purposively selected patients with intra articular distal humerus fractures treated by surgical intervention with different hardware who were admitted to Mymensingh Medical College and Hospital, Bangladesh in between November 2016 to October 2018. Surgical approaches were standard dorsal with or without olecranon osteotomy. The mean age of the patients was 32.3 years, range between 18-55 years. The maximum patients i.e. 85% were between 18-45 years. Seventy percent (70%) of the cases admitted were due to Road traffic accident (RTA). Most of the patients were males 14(70%) with right upper limb was involved in 13(65%) cases. Mean Mayo Elbow Performance Score was 81.5 post-operatively. According to Mayo Elbow Performance (MEP) score clinical outcome was excellent in 20%, good in 50%, fair in 25% and poor in 10% of patients. Distal humerus fractures are censorious in nature. Proper anatomical articular reconstruction and stable fixation by surgical intervention helps in fruitful results.

Diagnostic dilemma of dengue fever: how much reliability are there in rapidity.

Rapid diagnosis of dengue infection is essential to patient management and disease control. In a rural tertiary health setting and diagnostic laboratories, dengue suspect cases were assessed with a rapid (15 minutes) immunochromatographic test and compared to an IgM capture enzyme-linked immunosorbent assay (ELISA) (2-3 days) and the reliability of the rapid test was tested. The objectives were to evaluate dengue rapid test against dengue IgM capture ELISA and to assess the scopes of such rapid tests in peripheral setting. A rapid immunochromatographic card test was compared with an IgM capture ELISA (National Institute of Virology, Pune, India) as the reference gold standard. The sensitivity and specificity of the test was compared over a period of five years in a rural tertiary hospital among 158 dengue suspects. The rapid test showed good sensitivity in the diagnosis of both primary and secondary dengue infection. The rapid test as confirmed by IgM capture ELISA was found to have specificity of 98.4% and a sensitivity of 96.4%.The positive predictive value was 93.1% and negative predictive value of 99.2%.The positive likelihood ratio worked out to be 62.6,with negative likelihood ratio was 0.036,signifying large impact. The rapid tests may be useful aid in screening in case of clinical diagnosis of dengue infection,particularly valuable in peripheral health settings,where it can hasten the initiation of firstline of management; while the ELISA has a place in central testing laboratories, aiding in resource optimisation.

Treatment of advanced cervical cancer: a population-based study.

Chemoradiation is the standard treatment for locally advanced cervical cancer. We report how our population were treated over a 6-year period. Approximately 78.7% of all patients with advanced cervical cancer received chemoradiation, which appears to be well tolerated and acceptable to patients.

Freehand core biopsy in breast cancer: an accurate predictor of tumour grade following neoadjuvant chemotherapy?

Core biopsy is an increasingly used technique in the pre-operative diagnosis of breast carcinoma, as it provides useful prognostic information with respect to tumour type and grade. Neoadjuvant chemotherapy is being used in the treatment of large and locally advanced breast cancers but little is known regarding the correlation between tumour histology on pre-treatment core biopsy and that in residual tumour following primary chemotherapy and surgery. This study aimed to evaluate the accuracy of core biopsy in predicting these features in patients treated with primary chemotherapy. One hundred and thirty-three patients with carcinoma of the breast diagnosed on clinical, radiological and cytological examination underwent core biopsy, followed by primary chemotherapy (with cyclophosphamide, vincristine, doxorubicin and prednisolone) and surgery. The false-negative rate for pre-treatment core biopsy was 14%, with 91% agreement between the grade demonstrated on core biopsy and that in the residual tumour following completion of chemotherapy. Tumour type in the residual post-chemotherapy tumour was predicted by core biopsy in 84%. This study suggests that pre-treatment core biopsy histology accurately predicts residual tumour histology following primary chemotherapy and surgery in patients with breast cancer.

A reappraisal of the role of chlorambucil in patients with end stage ovarian cancer who have previously been treated with platinum regimens.

The role of chlorambucil in end stage platinum resistant epithelial ovarian cancer was evaluated in women with end stage ovarian cancer. They had received platinum based chemotherapy and all other intravenous chemotherapeutic options had been exhausted. Over a 15 year period, 30 patients were identified. The median age was 64.5 years (range 45-81). The median number of chlorambucil pulses was 4 (range 1-16). The median survival following the introduction of chlorambucil was 5.5 months (range 0.72-38.8). The 22 patients who survived for longer than three months were significantly younger than those who did not (p = 0.03). Apart from two patients who developed transient myelosupression there were no toxic side effects. Chlorambucil should be considered as a therapeutic option in end stage ovarian cancer. It is has minimal toxicity, and can be prescribed safely for long term use. In younger women, an increase in benefit may be anticipated.

Psychological, clinical and pathological effects of relaxation training and guided imagery during primary chemotherapy.

The diagnosis and treatment of breast cancer are stressful, and stress may be associated with a poorer response to chemotherapy. There is a need, therefore, to develop and evaluate interventions that might enhance quality of life and, possibly, improve treatment response. The effects of relaxation combined with guided imagery (visualizing host defences destroying tumour cells) on quality of life and response to primary chemotherapy, to date, have not been adequately evaluated. Ninety-six women with newly diagnosed large or locally advanced breast cancer (T2 > 4 cm, T3, T4, or TxN2 and M0) took part in a prospective, randomized controlled trial. Patients were randomized following diagnosis to a control condition (standard care) or to the experimental condition (standard care plus relaxation training and imagery). Psychometric tests to evaluate mood and quality of life were carried out before each of the six cycles of chemotherapy and 3 weeks after cycle 6: tests of personality and coping strategy were carried out prior to cycles one and six. Clinical response to chemotherapy was evaluated after six cycles of chemotherapy using standard UICC criteria and pathological response was assessed from the tissue removed at surgery. As hypothesized, patients in the experimental group were more relaxed and easy going during the study (Mood Rating Scale). Quality of life was better in the experimental group (Global Self-assessment and Rotterdam Symptom Checklist). The intervention also reduced emotional suppression (Courtauld Emotional Control Scale). The incidence of clinically significant mood disturbance was very low and the incidence in the two groups was similar. Finally, although the groups did not differ for clinical or pathological response to chemotherapy, imagery ratings were correlated with clinical response. These simple, inexpensive and beneficial interventions should be offered to patients wishing to improve quality of life during primary chemotherapy.

Psychological factors can predict the response to primary chemotherapy in patients with locally advanced breast cancer.

This study evaluated the possible value of psychological variables in predicting clinical and pathological response to primary chemotherapy. 96 women with newly diagnosed large, or locally advanced, breast cancer (T2 > 4 cm, T3, T4, N2 and M0) participated in a prospective, randomised trial to evaluate the effects of relaxation training with guided imagery and L-arginine on response to primary chemotherapy. Before the first of six cycles of primary chemotherapy, women were assessed using the Hospital Anxiety and Depression Scale (HADS) and the Eysenck Personality Questionnaire (EPQ). The primary outcomes were clinical response (evaluated using standard International Union Against Cancer (UICC) criteria) and pathological response (graded by means of a previously published 5-point scale) following primary chemotherapy. Stepwise linear regressions were used to estimate the predictive value of age, menopausal status, clinical nodal status, tumour size at diagnosis, oestrogen receptor status, dietary supplementation (L-arginine versus placebo), personality (EPQ-L scores), mood (HADS scores) and a psychological intervention. HADS depression score was a significant independent predictor of pathological response to chemotherapy. HADS anxiety score was a significant independent predictor of clinical response. Because the original tumour size before chemotherapy (also a significant predictor of clinical and pathological responses) was taken into account in the analyses, the results cannot be explained in terms of psychobiological factors related to tumour size. This study supports the importance of psychological factors as independent predictors of response to primary chemotherapy in patients with breast cancer. If they can be replicated, these findings have major implications for the management of women with breast cancer. Psychological factors need to be assessed and evaluated in future trials of chemotherapy.

Acute phase proteins in patients with large and locally advanced breast cancer treated with neo-adjuvant chemotherapy: response and survival.

Seventy-seven patients with locally advanced breast cancer were treated with multimodality therapy comprising of six pulses of neo-adjuvant chemotherapy (doxorubicin, cyclophosphamide, vincristine and prednisolone) at 21-day intervals, followed by surgery (breast conservation or mastectomy) with appropriate axillary surgery, radiotherapy and adjuvant tamoxifen. The serum concentrations of acute phase proteins, C-reactive protein (CRP), á-1-anti-trypsin, albumin and transferrin were measured in serum taken prior to commencement of treatment. Patients were followed up for a median of 31 months and their clinical and histological responses and overall survival recorded. Univariate analyses revealed that tumour stage (p=0.01), clinical lymph node status (p=0. 02) and pre-treatment levels of serum albumin (p=0.002) and á-1-anti-trypsin (p=0.06) predicted overall survival. Using the Cox proportional hazards model reduced pre-treatment levels of serum albumin (p<0.00001), progressive lymph node involvement with tumour (p<0.005), and advancing tumour stage (p<0.01) were independent prognostic indicators for a poorer survival in patients with locally advanced breast cancer receiving neo-adjuvant chemotherapy.

Treatment of large and locally advanced breast cancers using neoadjuvant chemotherapy.

BACKGROUND: Neoadjuvant (primary) chemotherapy is being used increasingly in the treatment of patients with large and locally advanced breast cancer with the aim of reducing the size of the primary tumor and eliminating micrometastatic disease. Response rates to, compliance with, and survival of patients following neoadjuvant chemotherapy have been variable. We report the results of a consecutive series of 77 patients with breast cancer who received neoadjuvant chemotherapy. METHODS: Seventy-seven patients with locally advanced breast cancers were treated with multimodality therapy comprising up to six cycles of chemotherapy (cyclophosphamide, vincristine, doxorubicin, and prednisolone), radiotherapy, and then surgery. The median follow-up was 54 months. Clinical response rates to therapy and overall survival have been documented. In addition, prognostic factors for survival were identified using the Cox proportional hazards model. RESULTS: The overall objective response rate of the primary tumor to chemotherapy alone was 87% (25% complete and 62% partial responses, UICC criteria). Following radiotherapy the response rate was 90% (52% complete and 38% partial responses). The overall 5-year survival for all patients was 0.48. However, the probability of survival at 5 years was 0.74 in those with a complete response, and 0.36 if there was a partial clinical response, but no patients who had either stasis of disease or progression survived for 5 years. Independent predictors of better survival that were identified were a complete histopathological response after chemotherapy and radiotherapy, a complete clinical response to chemotherapy, and five or six cycles of chemotherapy versus four or less. CONCLUSIONS: Neoadjuvant chemotherapy in patients with large and locally advanced breast cancers can result in satisfactory local control and overall survival rates, especially in patients with a complete clinical or histopathological response after treatment.

Mature results of a randomized trial of two doses of cisplatin for the treatment of ovarian cancer. Scottish Gynecology Cancer Trials Group.

PURPOSE: In 1992, we reported the first results of a randomized study in ovarian cancer, comprising two doses of cisplatin and indicated a significant difference (P = .0008) in median survival. Four years later, we now describe the results of this trial. PATIENTS AND METHODS: After a median follow-up of 4 years and 9 months, 115 of 159 cases of advanced ovarian cancer, originally randomized to receive six cycles of cyclophosphamide 750 mg/m2 and either a high dose (HD) of 100 mg/m2 cisplatin or a low dose (LD) of 50 mg/m2 (LD) cisplatin, have now died. RESULTS: The overall survival for HD and LD patients is 32.4% and 26.6%, respectively, and the overall relative death rate is 0.68 (P = .043). This represents a reduction in overall benefit with longer follow-up compared with the first 2 years (relative death rate of 0.52). Toxicity, particularly neurotoxicity, is still evident in the fourth year (10/31 on HD compared with 1/24 on LD). CONCLUSION: Our recommended dose of cisplatin in combination schedule is therefore 75 mg/m2, representing the optimal balance between efficacy and toxicity.

Upper-limb arterial disease in women treated for breast cancer.

A 5-year cohort of patients treated 15-19 years previously for breast cancer was studied to establish the prevalence of symptoms and objective evidence of circulatory insufficiency in the upper limbs. There were 187 survivors of the original cohort of 665. In all, 102 patients were evaluated; 50 had received radiotherapy in addition to surgery. Irradiated and non-irradiated groups were comparable for age, extent of axillary dissection and vascular risk factors. Both arms were assessed for symptoms and examined by Doppler ultrasonographically derived segmental pressures and hyperaemia testing, Doppler ultrasonographic waveform analysis, pulse volume recording and venous outflow air plethysmography. Seven ipsilateral arms (14 per cent) in patients given radiotherapy were symptomatic, compared with four (8 per cent) in those receiving surgery alone, and two contralateral control arms (2 per cent). Evidence of arterial disease was found in 11 ipsilateral arms of patients given radiotherapy (22 per cent) and two ipsilateral arms of those receiving surgery alone (4 per cent) (P < 0.03). There was no association between symptoms and evidence of arterial disease, and no evidence of abnormal venous function.

Dietary supplementation with L-arginine in patients with breast cancer (> 4 cm) receiving multimodality treatment: report of a feasibility study.

L-Arginine has been shown, in human breast cancers, to increase protein synthesis and the number of cells in the growth phase of the cell cycle. L-Arginine, therefore, may potentiate the response of breast cancers to cell cycle-specific cytotoxic agents. This phase II pilot study assessed the clinical, radiological and pathological responses in 44 patients with breast cancers > 4 cm in diameter (46 tumours: T2, n = 6; T3, n = 22; T4, n = 19), who received oral L-arginine 30 g day-1 for 3 days prior to each cycle of CHOP chemotherapy, followed after 4-6 cycles by radiotherapy. Following this treatment, 95% of patients had a clinical response: complete response in 30% and partial response in 65%. Imaging, ultrasound and mammography revealed response rates of 91% and 76% respectively. Surgery was performed in 43 patients. Histological examination revealed that in 18% of cases there was no residual evidence of tumour. Furthermore, if residual tumour was identified, the degree of destruction was graded as 'severe' in 36% and 'moderate' in 30% of cases. Further studies are now required to evaluate the potential beneficial use of nutritional pharmacology in combination with existing treatment regimens.

Multimodality treatment in the management of locally advanced breast cancer.

Forty-two patients with locally advanced breast cancer were treated with multimodality therapy comprising neoadjuvant chemotherapy (cyclophosphamide, vincristine, doxorubicin and prednisolone) and radiotherapy to the breast and lymph-draining areas, followed by tamoxifen and then selective surgery. The objective response rate (UICC criteria) of the primary tumours to chemotherapy alone was 72%, which increased to 83% following radiotherapy. The patients have been followed up for 13-56 months and the probability of local control at 36 months was 0.83. The probabilities of distant disease-free survival and overall survival were 0.50 and 0.65 respectively, at 36 months. However, if the patients' breast cancers had shown a response to chemotherapy/radiotherapy then the distant disease-free survival and overall survival of these subgroups of patients were 0.61 and 0.83 respectively, at 36 months. Toxicity included nausea, vomiting, alopecia, and peripheral neuropathies (two patients), but with no episodes of severe infection or bleeding. This multimodality therapy has achieved good local control and satisfactory overall and distant disease-free survivals with excellent patient compliance.

Primary hepatocellular carcinoma in a patient with breast carcinoma.

We report the case of a patient who presented with a carcinoma of her right breast with ipsilateral axillary lymph node involvement whose staging investigations were otherwise normal. In addition to surgery she received a course of CMF chemotherapy and tamoxifen. Within six months of the diagnosis of breast carcinoma being made, the patient presented as an emergency with widespread intra-abdominal disease from a primary hepatocellular carcinoma. We have not previously witnessed the development of a second primary malignancy in a patient who has already received medication considered to be beneficial in the treatment of both types of malignancy. An extensive literature search has failed to reveal a similar case. The question of immunosuppression secondary to treatment with CMF chemotherapy is raised, and we suggest that perhaps a simple percutaneous biopsy of apparent liver metastases be performed under ultrasound control so as to determine the origin of liver disease in patients with breast carcinoma.

Intravenous treosulfan versus intravenous treosulfan plus cisplatinum in advanced ovarian carcinoma.

In a prospective, multicentre, randomized trial, the efficacy and tolerance of treosulfan alone was compared with that of treosulfan plus cisplatinum in 135 women with advanced ovarian carcinoma. No statistically significant difference was found between the two treatments in terms of median survival. Combined treatment was associated with significantly greater side-effects and haematological toxicity. Optimal survival with minimal toxicity can be achieved by using treosulfan alone in patients (mainly stages Ic or II) with minimal postoperative residual disease. Patients (likely to be stage III or IV) with greater residual disease should receive treosulfan plus cisplatinum.

Primary Streptococcus viridans pneumonia.

We describe three cases of acute uncomplicated bacterial pneumonia due to viridans streptococci in previously healthy adults, which were indistinguishable from those caused by other well-known respiratory pathogens. On arrival, all of these patients were treated with IV aqueous penicillin based on Gram stain of sputum which showed predominant Gram-positive cocci in pairs and chains. These specimens of sputum grew normal oral flora in the three cases. The diagnosis was confirmed by positive blood cultures in all three patients from each of two separate samples of blood. The isolates were identified as S uberis. There is no precedent in the literature of primary pneumonia due to viridans streptococci complicated by bacteremia in normal adults. We wonder if primary pneumonia due to viridans streptococci is not as rare as has been reported in the literature. Also, Gram stain of the sputum had a very significant contribution in the initial management of these patients. All of these patients subjectively showed improvement in 24 hours and became afebrile within three days of starting penicillin therapy.
