A case of Hodgkin's disease presenting with recurrent laryngeal nerve palsy and tracheoesophageal fistula

Malignancy is the most common cause of tracheoesophageal fistulas. The malignancies commonly implicated in the development of tracheoesophageal fistulas are primary bronchial or esophageal carcinomas. Hodgkins disease rarely leads to such a fistula. We report a case of Hodgkin's disease with a tracheoesophageal fistula as well as a left recurrent nerve palsy at presentation. This presentation has no precedent in literature. The patient was treated with systemic chemotherapy and involved field radiotherapy. On follow up 1 year after the completion of treatment, he was clinically and radiologically disease free.     

Misoprostol as aid in First Trimester MTP

Background

Medical Termination of Pregnancy (MTP) is a commonly performed during the first trimester. Dilatation and Evacuation (D & E) mandates rapid dilatation of cervix with metal dilators, which requires anaesthesia and may be associated with trauma to the uterus, cervix and later cervical incompetence. The problem of rapid cervical dilatation is obviated with intravaginal misoprostol.

Methods

Intravaginal misoprostol tablet 200 microgram was inserted, a night prior to MTP to ripen the cervix. Cervix was dilated with metal dilators only in cases where cervix did not loosen up sufficiently. Products of conception were removed by suction.

Results

Out of 108 cases cervical dilatation was not required in 96 cases (88.9%).

Conclusion

Intravaginal misoprostol 200 microgram proved effective as a priming agent prior to MTP in the first trimester.Key Words: Misoprostol, MTP     

Childhood osteosarcoma of greater wing of sphenoid: case report and review of literature

Primary osteosarcoma of skull base is extremely rare. We present a case of primary osteosarcoma arising in greater wing of sphenoid in a child. Our patient had an incomplete excision after which he received adjuvant chemotherapy and radiotherapy. There was good response to adjuvant chemoradiotherapy and the patient is disease free at a follow-up of 18 months. Treatment of skull base osteosarcomas is difficult, as complete excision is often not possible. To the best of our knowledge, this is the first case of sphenoid wing osteosarcoma in childhood to be reported in literature.     

Functional variants of IL4 and IL6 genes and risk of tobacco-related oral carcinoma in high-risk Asian Indians

Oral Diseases (2011) 17 , 720–726 Background: Tobacco‐related oral squamous cell carcinoma (OSCC) is one of the most common cancers involving Indian males. We assessed the association of IL4 promoter –589 T>C, –33 T>C, and IL6–174 G>C functional genetic polymorphisms with tobacco‐related OSCC in Asian Indians. Patients and Methods: The IL4 and IL6 promoter polymorphisms were assessed in 140 patients with OSCC and 120 normal subjects by PCR–RFLP technique, and significance of the data was determined using chi‐square test. Results: The frequency of TC, CC genotype, and C allele at IL4 promoter sites –589 and –33 were higher in patients when compared with controls. Consequently, TC/CC genotypes and C allele at both sites appeared as susceptible. However, IL6–174 G>C single‐nucleotide polymorphisms (SNP) appeared to be protective in patients with OSCC. Of eight haplotypes, five were associated with two‐ to seven‐fold increased risk of tobacco‐related OSCC. These SNPs further showed heterogeneity among different ethnic population, but their distribution in Asian Indians stand closer to other Asian populations. Conclusions: In this study, IL4–589 CC, –33 CC genotype, and *C allele at both sites appeared to be susceptible, while IL6–174 CC genotype and *C allele appeared to be protective in patients with OSCC; hence, these SNPs may be a potential prognostic markers for tobacco‐related OSCC in Asian Indians.     

Effect of recombinant human interleukin-6 (rhIL-6) and rhIL-3 on hematopoietic regeneration as demonstrated in a nonhuman primate chemotherapy model

Using a recently developed hepsulfam-induced pancytopenia model in rhesus macaques, we have studied the effects of recombinant human interleukin-6 (rhIL-6) and rhIL-3 on marrow regeneration. Control animals were given hepsulfam (1.5 g/m2 by a single 30-minute intravenous [i.v.] injection, n = 4), while study animals received hepsulfam followed by rhIL-6, rhIL-3, or a combination of rhIL-6 and rhIL-3 (n = 3 per study group). Each cytokine was administered by once- daily subcutaneous (SC) injection (15 micrograms/kg/d) for 3 weeks beginning the day after chemotherapy (days 2 through 22). Mean platelet counts in control animals were < 100,000/microL on days 15 through 24, with 50% of the counts < 50,000/microL and two of four animals requiring platelet transfusion. In the rhIL-6- and rhIL-6/rhIL-3- treated groups, the nadir mean platelet counts were 164,000 +/- 58,700/microL and 162,300 +/- 23,800/microL, respectively, and occurred on day 15. Platelet counts in the rhIL-3-treated group were similar to those in controls. Mean absolute neutrophil counts (ANCs) < 1,000/microL occurred on days 10 through 29 in control animals, days 8 through 15 in rhIL-6-treated animals, and days 6 through 8 and 13 in rhIL-6/rhIL-3-treated animals. The frequency of ANCs < 500/microL was significantly less in the rhIL-6- and rhIL-6/rhIL-3-treated groups versus control groups (2.7 +/- 0.6 and 2.0 +/- 1.0 vs 7.0 +/- 1.4 occurrences, respectively; P < .05). rhIL-3-treated animals had ANCs similar to those in controls; one animal died with septicemia on day 21. Monkeys receiving rhIL-6 were significantly more anemic during the cytokine administration period; however, the anemia resolved by day 24. Coadministration of rhIL-3 and rhIL-6 partially corrected the anemia. The data indicate that rhIL-6 prevents significant thrombocytopenia and shortens the neutropenic period in this chemotherapy model.     

Assessment of knowledge and attitude about basic life support among dental interns and postgraduate students in Bangalore city,India

BACKGROUND: Life-threatening emergencies can occur at anytime, at anywhere and in anyone. Effective management of an emergency situation in the dental office is ultimately the dentist's responsibility. The lack of training and inability to cope with medical emergencies can lead to tragic consequences and sometimes legal complications. Therefore, health professionals including dentists must be well prepared to deal with medical emergencies. This study was undertaken to assess the knowledge about and attitude towards basic life support(BLS) among dental interns and postgraduate students in Bangalore city, India.METHODS: A cross sectional survey was conducted among dental interns and postgraduate students from May 2014 to June 2014 since few studies have been conducted in Bangalore city. A questionnaire with 17 questions regarding the knowledge about and attitude towards BLS was distributed to 202 study participants.RESULTS: The data analyzed using the Chi-square test showed that dental interns and postgraduate students had average knowledge about BLS. In the 201 participants, 121(59.9%) had a positive attitude and 81(40.1%) had a negative attitude towards BLS.CONCLUSIONS: Cardiopulmonary resuscitation should be considered as part of the dental curriculum. Workshops on a regular basis should be focused on skills of cardiopulmonary resuscitation for dental students.
