Comparative study between liquid-based cytology & conventional Pap smear for cytological follow up of treated patients of cancer cervix

Background & objectives: Cancer cervix is one of the most common forms of genital malignancy among Indian women. Recurrence is seen in a significant number of cases. The conventional cervical smear technique has inherent problems and screening and interpretation errors. This study was undertaken to assess the efficacy of liquid-based cytology (LBC) as a method for cytological follow up and detection of recurrence in treated cases of cancer cervix and to compare it with conventional Pap smear technique to find the best screening method for detection of recurrence in these patients. Methods: This cross-sectional study was conducted over a period of one year. Patients attending Gynecology and Radiotherapy outpatient departments for follow up after treatment of cancer cervix were included. Pap smear and LBC were taken in all cases. Colposcopy and biopsy were done for those having epithelial cell abnormality in cytology report. Colposcopy and biopsy were taken as gold standard for diagnosis of cancer cervix recurrence. Results: Ninety four treated patients of carcinoma cervix were studied. The diagnostic accuracy for detection of recurrence of conventional Pap smear was 79.16 per cent, and that of LBC was 97.6 per cent. The difference between the two methods was significant (P<0.001). Interpretation & conclusions: Our findings showed that LBC performed better than the conventional method of cytology to detect recurrence of squamous cell carcinoma. Its sensitivity, specificity as well as accuracy were much higher than conventional method. LBC can be a better method of cytological follow up of post-treated patients of cancer cervix.

Superbugs causing ventilator associated pneumonia in a tertiary care hospital and the return of pre‑antibiotic era.

The rise in super bugs causing Ventilator‑Associated Pneumonia (VAP) is a major cause of mortality and morbidity despite recent advances in management owing to the looming ‘antibiotic apocalypse’. The aetiology and susceptibility pattern of the VAP isolates varies with patient population, type of intensive care unit (ICU) and is an urgent diagnostic challenge. The present study carried out for a period of one year in a tertiary care hospital, enrolled patients on mechanical ventilation (MV) for ≥48 hrs. Endotracheal aspirates (ETA) from suspected VAP patients were processed by semi quantitative method. Staphylococus aureus, members of Enterobacteriaceae were more common in early onset VAP (EOVAP), while Nonfermenting Gram negative bacilli (NFGNB) were significantly associated with late onset VAP (LOVAP). Most of the isolates were multi drug resistant (MDR) super bugs. With limited treatment options left for this crisis situation like the pre‑antibiotic era; it is an alarm for rational antibiotic therapy usage and intensive education programs.

Mixed pulmonary infection in an immunocompromised patient: A rare case report.

Patients who are immunocompromised are predisposed to a variety of common and uncommon pulmonary infections. We report a case of mixed pulmonary infection by drug resistant tuberculosis with a nocardiosis in a 49-year-old man who was a known case of chronic obstructive pulmonary disease, on prolonged corticosteroid use with diabetes mellitus. Chronic use of corticosteroids is a predisposing factor for opportunistic infections, such as nocardiosis or tuberculosis. Since such a mixed infection is rare, maybe a combined approach to therapy early in the course of disease would be effective in such cases.

Acute ischemic stroke in a child with cyanotic congenital heart disease due to non-compliance of anticoagulation / 世界急诊医学杂志（英文）

BACKGROUND: Stroke is a common presentation in geriatric patients in emergency department but rarely seen in pediatric patients. In case of acute ischemic stroke in pediatric age group, management is different from that of adult ischemic stroke where thrombolysis is a good option.METHODS: We report a case of a 17-year-old male child presenting in emergency with an episode of acute ischemic stroke causing left hemiparesis with left facial weakness and asymmetry. The patient suffered from cyanotic congenital heart disease for which he had undergone Fontan operation previously. He had a history of missing his daily dose of warfarin for last 3 days prior to the stroke.RESULTS: The patient recovered from acute ischemic stroke without being thrombolyzed.CONCLUSION: In pediatric patients, acute ischemic stroke usually is evolving and may not require thrombolysis.

Cervical lymph node metastases of squamous cell carcinoma from an unknown primary: Outcomes and patterns of failure.

Context: Management of cervical lymph nodes metastases of squamous cell carcinoma (SCC) from primary of unknown origin (PUO) is contentious and there is insignificant data from India on this subject. Aims: To present experience of management of these patients treated with curative intent at a single institution. Settings and Design: Retrospective study of patients treated between 1989-1994 in a tertiary referral cancer centre. Materials and Methods: Eighty-nine patients were evaluated in the study period and their survival compared with patients with common sites of primary in the head and neck with comparable node stage. Statistical analysis used: Kaplan-Meier method. Results: The clinical stage of the neck nodes at presentation was N1 in 11%, N2a in 28.5%, N2b in 22.5%, N3 in 35% and Nx in 3.4% patients. All patients underwent surgery and 70 patients received more than 40Gy postoperative radiotherapy. Twenty-nine (32.6%) patients had relapse of which 19 (21%) were in the neck. Postoperative radiotherapy did not influence the neck relapse (p=0.72). Primary was detected in 13 patients (14.6%) on subsequent follow up. The overall five and eight-years survival was 55% and 51% respectively. The overall five-year survival was better compared to patients with known primary with comparable node stage. Conclusions: Patients with cervical lymph nodes metastases of SCC from PUO have reasonable survival and low rate of development of subsequent primary when treated with surgery and radiotherapy. The overall survival is comparable to that of patients with known primary and hence an attempt at cure should always be made.

Breast metastases of gastric signet ring cell carcinoma: a differential diagnosis with primary breast signet ring cell carcinoma.

Metastatic deposits within the breast may be difficult to distinguish from primary breast carcinoma. Radiological features and immunohistochemistry especially for steroid hormone receptors and expression of gross cystic disease fluid protein may be helpful in differentiating these two conditions. In this report, we present a case of signet ring cell stomach cancer with metastasis to the breast and discuss the differential diagnostic options.

Chest wall metastases from unknown primary hepatocellular carcinoma.

Metastases of hepatocellular carcinoma (HCC) to the bones are common but bone metastases of hepatocellular carcinoma in the presence of a normal liver are an uncommon entity. A 50-year-old male patient presented with a rapidly growing tumour on the sternum. Biopsy of the lesion showed metastatic sternal tumour from a primary hepatocellular carcinoma. Radiological evaluation however, failed to detect a primary lesion in the liver. Bone metastases of hepatocellular carcinoma localized to the chest wall in the presence of a normal liver are scarcely reported as anecdotal case reports in the literature.

A prospective study of pharyngocutaneous fistulas following total laryngectomy.

Pharyngocutaneous (PC) fistula is a common complication following laryngectomy. It leads to increased morbidity, delay in adjuvant treatment, prolonged hospitalization and an increase in treatment costs. Although a number of factors that result in PC fistula have been described, there is still no agreement on the most significant factors. We undertook a prospective study to critically analyze PC fistula and its association with various tumors, patient and treatment related factors. This was a prospective study that included 143 patients who underwent laryngeal surgery for squamous cell carcinoma of the larynx and pyriform sinus. Use of pectoralis major myocutaneous flap to reconstruct the neopharynx, primary disease in pyriform and extensive soft tissue infiltration were significantly associated with PC fistula. Prior treatment (radiotherapy and chemotherapy), type of closure (T closure, Y closure and vertical closure), Layers of closure (full thickness interrupted, submucosal interrupted, submucosal continuous) type of suture material (silk, vicryl ), age, sex, stage, preoperative tracheostomy, cut margin status, pre/postoperative hemoglobin and experience of surgeons did not relate significantly.
