Comparison of Outcome of Borderline and Normal Amniotic Fluid Index in Term Pregnancy.

Background Determination of Amniotic Fluid Index (AFI) is an important component of antepartum assessment of all normal pregnancies. Objective To compare the obstetric interventions and neonatal outcomes in term pregnancies with borderline Amniotic Fluid Index versus normal Amniotic Fluid Index. Method This hospital based prospective study was conducted at Tribhuwan University Teaching Hospital over 1 year between 2017 and 2018 in 128 women having uncomplicated term pregnancy admitted in labor ward. Of the 128 women, 64 women had borderline Amniotic Fluid Index (5.1-8 cm) and 64 normal AFI (8.1 - 24 cm). Parameters studied were induction of labor, cesarean section, instrumental delivery, intrapartum abnormal fetal heart rate, meconium staining of liquor, APGAR score at 5 and 7 minutes, birth weight, neonatal intensive care unit (NICU) admission and neonatal death. Data was analyzed using software OpenEpi. Result Statistically significant difference in result was obtained in the two groups in terms of rate of induction of labor (73.4% vs 35.9%, p = 0.0001, OR = 4.9), rate of cesarean section (42.1% vs 28 .1%, p = 0.04, OR = 1.8), tachypnea (50% vs 11.1%, p = 0.01) and low birth weight (9.1% vs 4.5%, p = 0.04). No statistical significance was found in meconium staining of liquor (33% vs 38.3%, p = 0.3) and APGAR score of <7 at 5 minutes (3.1% vs 1.5%, p = 0.06). There were no neonatal intensive care unit admissions and neonatal mortality in any of the babies. Conclusion Detection of amniotic fluid volume at term is important for timely maternal interventions to improve the overall fetal outcome.

Oncological outcome after MRI-based selection for neoadjuvant chemoradiotherapy in the OCUM Rectal Cancer Trial.

BACKGROUND: It is not clear whether all patients with rectal cancer need chemoradiotherapy. A restrictive use of neoadjuvant chemoradiotherapy (nCRT) based on MRI findings for rectal cancer was investigated in this study. METHODS: This prospective multicentre observational study included patients with stage cT2-4 rectal cancer, with any cN and cM0 status. Carcinomas in the middle and lower third that were 1 mm or less from the mesorectal fascia, all cT4 tumours, and all cT3 tumours of the lower third were classified as high risk, and these patients received nCRT followed by total mesorectal excision (TME). All other carcinomas with a minimum distance of more than 1 mm from the mesorectal fascia and those in the upper third were classified as low risk; these patients underwent TME alone (no nCRT). Patients were followed for at least 3 years. Outcomes were the rates of local recurrence, distant metastasis and survival. RESULTS: Among 545 patients included, 428 were treated according to the study protocol: 254 (59·3 per cent) had TME alone and 174 (40·7 per cent) received nCRT and TME. Median follow-up was 60 months. The 3- and 5-year local recurrence rates were 1·3 and 2·7 per cent respectively, with no differences between the two treatment protocols. Patients with disease requiring nCRT had higher 3- and 5-year rates of distant metastasis (17·3 and 24·9 per cent respectively versus 8·9 and 14·4 per cent in patients who had TME alone; P = 0·005) and worse disease-free survival compared with that in patients who did not need nCRT (3- and 5-year rates 76·7 and 66·7 per cent, versus 84·9 and 76·0 per cent in the TME-alone group; P = 0·016). CONCLUSION: Restriction of nCRT to high-risk patients achieved good results.

Comparing 5-Year Survival Rates Before and After Re-stratification of Stage I-III Right-Sided Colon Cancer Patients by Establishing the Presence/Absence of Occult Tumor Cells and Lymph Node Metastases in the Different Levels of Surgical Dissection.

BACKGROUND: To establish the impact of re-stratification on the outcomes of patients (stage I-III right-sided colon cancer) based on the presence/absence of occult tumor cells (OTC) and/or metastatic lymph nodes in the different levels of surgical dissection. METHODS: Consecutive patients were drawn from a multicenter prospective trial. After surgery, the surgical specimen was divided into the D1/D2 and D3 volumes before being further analyzed separately. All lymph nodes were examined with cytokeratin CAM 5.2 immunohistochemically. Lymph nodes containing metastases and OTC (micrometastases; isolated tumor cells) were identified. Re-stratification was as follows: RS1, stages I/II, no OTC in D1/D2 and D3 volumes; RS2, stages I/II, OTC in D1/D2 and/or D3; RS3, stage III, lymph node metastases in D1/D2, with/without OTC in D3; RS4, stage III, lymph node metastases in D3, with/without OTC in D3. RESULTS: Eighty-seven patients (39 men, 68.4 + 9.9 years) were included. The standard stratified (SS) group contained the following: stages I/II (SS1) 57 patients; stage III (SS2) 30 patients. Re-stratified (RS) contained RS1 (38), RS2 (19), RS3 (24), and RS4 (6) patients. Lymph node ratio (OTC) RS2: 0.157 D1/D2; 0.035 D3 and 0.092 complete specimens. Lymph node ratio RS3: 0.113 D1/D2; complete specimen 0.056. Overall survival and disease-free survival were p = 0.875 and p = 0.049 for SS and p = 0.144 and p = 0.001 for RS groups, respectively. CONCLUSION: This re-stratification identifies a patient group with poor prognosis (RS4). Removing this group from SS2 eliminates all the differences in survival between RS2 and RS3 groups. The level of dissection of the affected nodes may have an impact on survival.

Interactions of occult tumor spread and surgical technique on overall and disease-free survival in patients operated for stage I and II right-sided colon cancer.

PURPOSE: To determine if "medial to lateral" (ML) dissection with devascularization first is superior to "lateral to medial" (LM) dissection regarding numbers of lymph node micro metastases (MM) and isolated tumor cells (ITC) as well as 5-year disease-free (5YDFS) and 5-year overall survival (5YOS) in stage I/II right-sided colon cancer. METHODS: Two datasets are used. ML group consists of consecutive stage I/II patients from a prospective trial. LM group is the original dataset from a previous publication. All harvested lymph nodes are examined with monoclonal antibody CAM 5.2 (immunohistochemically). Lymph node harvest and 5YOS/5YDFS were compared between ML/LM groups, stage I/II tumors and MM/ITC presence/absence. RESULTS: 117 patients included ML:51, LM:66. MM/ITC positive in ML 37.3% (19/51), LM 31.8% (21/66) p = 0.54. The 5YDFS for patients in ML 70.6% and LM 69.7%, p = 0.99, 5YOS: 74.5% ML and 71.2% LM (p = 0.73). No difference in 5YDFS/5YOS between groups for Stage I/II tumors; however, LM group had an excess of early tumors (16) when compared to ML group, while lymph node harvest was significantly higher in ML group (p < 0.01) 15.1 vs 26.7. 5YDFS and 5YOS stratified by MM/ITC presence/absence was 67.5%/71.4%, p = 0.63, and 75.0%/71.4%, p = 0.72, respectively. Death due to recurrence in MM/ITC positive was significantly higher than MM/ITC negative (p = 0.012). CONCLUSION: Surgical technique does not influence numbers of MM/ITC or 5YDFS/5YOS. Presence of MM/ITC does not affect 5YOS/5YDFS but can be a potential prognostic factor for death due to recurrence.

Transanal endoscopic microsurgical submucosa dissection in the treatment of rectal adenomas and T1 rectal cancer.

BACKGROUND: The treatment of flat rectal adenomas is challenging. The technical difficulty and the potential of malignancy in suspected benign lesions are the factors in question. Surgical and interventional endoscopic techniques are implemented in Europe without a clear strategy. To minimize recurrent adenoma and unclear histopathological work up en bloc excision is desirable. METHODS AND RESULTS: We demonstrate in this article the transanal endoscopic microsurgical submucosa dissection (TEM-ESD) procedure as a feasible method for en bloc excision of rectal adenomas and early rectal cancer. The surgical technique is demonstrated in detail with the help of a video of the operation that is available online. The results of a consecutive series of 78 patients are presented. CONCLUSION: TEM-ESD is a safe procedure for resection of rectal adenomas and low risk carcinomas. It offers the possibility of organ preservation and minimizes functional disturbances. In case of a necessary salvage operation, the preserved integrity of the rectal muscle tube grants maximal oncological safety.

[Spincter preservation after selective chemoradiotherapy of rectal cancer. Interim results of the OCUM study]. / Spinktererhalt nach selektiver Radiochemotherapie des Rektumkarzinoms. Zwischenergebnisse der OCUM-Studie.

BACKGROUND: In a prospective multicenter observational study (OCUM) neoadjuvant chemoradiotherapy (nRCT) was selectively administered depending on the risk of local recurrence and based on the distance between tumor and mesorectal fascia in pretherapeutic high-resolution magnetic resonance imaging (MRI). OBJECTIVE: Frequency and quality of abdominoperineal excision (APE) and sphincter preserving operations. PATIENTS AND METHODS: Of 642 patients treated in 13 hospitals 389 received surgery alone and 253 nRCT followed by surgery. By univariate and multivariate analysis risk factors for APE were determined. Quality parameters were the quality grade of mesorectal excision, the pathohistological involvement of the circumferential resection margin and intraoperative local dissemination of tumor cells. RESULTS AND DISCUSSION: In 12.8 % of the patients APE was performed. Independent risk factors for APE were tumor location in the lower third of the rectum and the individual hospitals, where APE varied between 0 and 32 %. This variation was chiefly caused by the different case mix. Hospitals with a high APE rate (> 30 %) treated significantly more patients with very low lying carcinomas (< 3 cm above the anal verge) and more advanced tumors. The median height of the tumor in cases of APE was nearly equal in all participating hospitals. Independent on the number of cases the quality of rectal surgery was high. Within the patient groups of primary surgery and nRCT the oncological quality parameter did not significantly differ between sphincter preservation and APE. As far as sphincter preservation is concerned the results justify a selective application of nRCT in patients with rectal carcinoma. The long-term results still have to be awaited.

Effectiveness of training of basic health workers in Leprosy Control Programme.

This study was undertaken in two adjacent districts (Rautahat and Parsa) in Nepal to measure the impact of training of basic health workers on Leprosy Control Programme. Knowledge, attitude and leprosy service delivery by them were studied before and after training. There was an improvement in all the three components after training. However, improvement was also seen in the control group as well. Possible reasons for this are discussed. Improper selection of the area and an inadequate methodology were the identified drawbacks of the study.

[Treatment with stents in the upper gastrointestinal tract]. / Stentbehandlung im oberen Gastrointestinaltrakt.

A wide range of therapeutic methods for treatment of malignant and benign stenoses of the upper gastrointestinal tract is at one's disposal with esophageal mechanical dilatation, laser therapy, insertion of plastic tubes and stent implantation. It has become routine to insert flexible metal stents in the treatment of esophageal carcinoma and tracheoesophageal fistula. Case reports exist describing the use of flexible metal stents in complicated benign esophageal stenoses of stomach and duodenum. Until January 1997 we implanted 18 stents (7 Z-stents[Wilson and Cook], 4 covered and 4 uncovered Ultraflex stents [Boston Scientific], 3 Endocoil stents [Instent]) in 15 patients. We treated patients with esophageal carcinoma, recurrent stenoses after gastrectomy and tracheoesophageal fistula. They were followed by questionnaires. Four days after stent implantation 50% of the patients were able to consume normal solid food, the other half semisolids. The main problem was the stent migration (28%). The decisive factors for stent migration were the quality of surface of the stent and its position in the gastroesophageal junction. The stents which were dislocated in the stomach could easily be extracted endoscopically. The endoscopic extraction of a dislocated Z-stent in the small bowel was impossible. The high rate of stent dislocation (20-30%) in distal stent position (gastroesophageal junction) is not to be tolerated with respect to the purchase price.

[Endoscopic palliation of malignant esophageal stenoses]. / Endoskopische Palliation maligner Osophagusstenosen.

The choice of the appropriate endoscopic procedure for treating a malignant esophageal obstruction depends on the tumor localisation, the tumor configuration, on specific patient data and last but not least on the technical possibilities of the hospital involved. Successfully performed is the mechanical dilatation, the tube insertion and stent implantation, the laser therapy, the argon plasma coagulation and the local sclerotherapy. The procedures differ in rate of complication, long term palliation and the improvement of dysphagia. In a case discussion we demonstrate that in the wide range of disease and patient specific facts that have to be dealt with, only the combined use of different endoscopic procedures will lead to the best results.

Vulvitis circumscripta plasmacellularis.

In this paper we present what is apparently the tenth published case of vulvitis circumscripta plasmacellularis (Zoon). The patient had eroded, red-brown, asymptomatic vulvar lesions that were recalcitrant to treatment. The characteristic histopathology--dense plasma cell infiltrate and deposition of hemosiderin--was present.

Development of Kondh women.

PIP: This article presents a profile of the living conditions of the Kondh ethnic group, with particular attention to women's conditions. The Kondhs are the largest tribal community in Orissa state, India. Kondh tribes are concentrated in Phulbani, Koraput, and Kalahandi districts. The Kondh consist of three subgroups. In Phulbani district the Kondh are one of several tribal populations and together with scheduled castes and tribes are the dominant populations. Phulbani district has limited educational resources and low levels of literacy, particularly among women. Female literacy in 1991 was only 16.59%. Girl's educational institutions are few in number and poor in quality. Female literacy is low due to parental ignorance of the importance of female education, the need to use girl children as domestic helpers, the cultural practice of facial tattooing that causes injury and shame among parents and children, the inadequacy of district schools, and the reputation of better private boarding as "cages." Economic life is based on a sexual division of labor, and women and men work according to their capacity. Agricultural tasks are shared, but men perform ploughing and clearing of jungle. Women perform all domestic tasks in addition collection of daily firewood and additional forest products that are sold jointed with husbands in local markets. During the slack agricultural periods, men relax and women work. Both men and women work if construction work is available nearby. Although tubewells were installed in villages, women prefer distant pond or stream water for drinking. The loss of tribal land for women places them in more vulnerable sexual and economic positions. Many voluntary groups promote land ownership for women as a means of security and social status. Phulbani district has little urbanization and no major industries. Bride-price was replaced by dowry, which downgrades Kondh women's status. The Kondh suffer from malnutrition, malaria, and anemia. Health services are insufficient, and Kondh cultural practices interfere with acceptance of modern medicine and healthy lifestyles.^ieng

Photoinduced dermal pigmentation in patients taking tricyclic antidepressants: histology, electron microscopy, and energy dispersive spectroscopy.

Two patients had been taking long-term tricyclic antidepressant therapy. Each developed a blue to slate-gray hyperpigmentation in sun-exposed areas. On histologic examination there were refractile golden brown granules free in the dermis along collagen bundles. Similar pigment was present in macrophages and along the basement membrane zone. The granules stained for melanin, but not for iron, and were bleached by the permanganate method. Electron microscopy showed varying size and shaped electron-dense granules within lysosomes and free in the dermis, which, in unstained sections, showed a less dense peripheral halo. This peripheral halo was also evident on light microscopy. Energy dispersive spectroscopy showed these granules to be rich in copper and sulfur (elements present in tyrosinase and pheomelanin, respectively). We believe that this represents a drug-melanosome complex, which is most likely caused by chronic photoactivation.

Lymphomatoid papulosis with antigen deletion and clonal rearrangement in a 4-year-old boy.

Lymphomatoid papulosis (LyP) is rarely seen in children. We report a case of LyP in a 4-year-old boy in whom immunopathologic studies demonstrated T cell antigen deletions. In contrast to all but two previous reports, a T suppressor (CD-8) phenotype was predominant. Southern blot analysis of DNA isolated from a typical skin lesion indicated a clonal rearrangement of the T cell receptor beta gene. Because of a 10% frequency of malignant lymphomas in patients with LyP, long-term observation is crucial, especially in children. We recommend routine clonal rearrangement studies for aid in diagnosis and follow-up, and as possible prognostic indicators in children with this condition.

Mass survey of leprosy in Lalitpur district, Nepal.

An intense mass survey of leprosy in Lalitpur District, Nepal, was carried for the period 1986 to 1990. This was the first such large scale survey in Nepal; 85% of the total population was examined. The 5-year case detection rate was 13 per 10,000; the 5-year child detection rate was 4 per 10,000. By the end of the survey the prevalence rate was 6.8 per 10,000; at the end of 1992 this had dropped to 2.2 per 10,000. In 1989, after a 3-year interval, a re-survey was done in three village development committees (VDCs) and 4 new cases were detected, bringing the 3-year case detection rate to 3.3 per 10,000; 36% of the old cases, 20% of the new adult cases, and 3% of the new child cases were classified as multibacillary. Overall, 62.7% of the patients had no disability, 18.8% had disability grade 1, and 12.7% had disability grade 2 while for 5.8% the data were incomplete. By the end of the survey 91% of the patients needing medical treatment were on multidrug therapy (MDT). At present this has increased to 100%. The regularity rate was 86%; at the end of 1992 this had increased to 96%. The cost for detecting one new patient was US$298. Because of the high cost, it is recommended that intense mass surveys not be performed when the estimated prevalence rate is less than 10 per 10,000 inhabitants. From the data collected conclusions were drawn and recommendations were formulated for developing new strategies for the National Leprosy Control Programme of the Government of Nepal.
