Maternal mortality in rural India: a hospital based, 10 year retrospective analysis.

OBJECTIVES: To estimate the maternal mortality ratio (MMR) in Ludhiana, a city of Northern India in order to determine the causes associated with MMR and to suggest ways to reduce it. METHODS: Retrospective analysis of the mortality records of obstetrics cases in Christian Medical College, Ludhiana, India. RESULTS: The mean MMR for the 10 year period was 785 per 100,000 live births. Of the total 116 reported maternal deaths, 44 (41.9%) were due to induced septic abortion. The reasons were unwanted pregnancy in 22 (50%) and 11 (25%) were female feticide. CONCLUSIONS: In our hospital based analysis, MMR was very high. Most maternal deaths are preventable by intervention at the appropriate time and it is important for health professionals, policy makers and politicians to implement the introduction of programs for reducing maternal mortality. Special emphasis should be placed on antenatal care, the establishment of a registration system and measures to abolish illegal abortion.

Clinical evaluation of human placental extract (placentrex) in radiation-induced oral mucositis.

To evaluate human placental extract in the treatment of radiation mucositis involving the oral/oropharyngeal region, a prospective randomized study was carried out in 120 patients with squamous cell carcinoma of the head and neck from August 1997 to March 1999. The study was conducted in patients receiving radical external radiation therapy, planned for = > 60 Gy/30 F/6 weeks, who developed grade 2 radiation mucositis (patchy mucositis) during radiation treatment. The patients were randomized in two groups of 60 patients each to receive either placentrex treatment (placentrex group) or conventional treatment (control group). Placentrex treatment was given as Inj Placentrex 2 ml by deep intramuscular injection 5 days a week for 15 injections. Conventional treatment given in the control group was disprin gargles and betamethasone oral drops. A subjective decrease in pain was observed in 48/60 (80%) of patients in the placentrex group compared with 22/60 (36.7%) in the control group. The progression to grade 3 radiation mucositis was 24/60 (40%) in the placentrex group compared with 52/60 (86.7%) in the control group. The subjective improvement in difficulty in swallowing was seen in 56/60 (93%) of patients in the placentrex group compared with 9/60 (15%) of patients in the control group. Only one patient in the placentrex group compared with three in the control group required interruption of radiation therapy because of severe radiation reactions. Human placental extract appears to be effective in the management of radiation-induced oral/oropharyngeal mucositis and especially in controlling subjective symptoms.

Is incidence of cancer on the decline in Delhi, capital of India?

The incidence of cancer varies to a great extent in the resident population of Delhi (Urban area). The purpose of this study is to examine the time trends of incidence rates in different sites (ICD.9) of cancer. Average Annual Age-Adjusted (world population) incidence rates by site (ICD.9) is used to estimate the parameters by linear regression method. Time trends analysis of 8 years from 1988 to 1995 in Delhi for age-adjusted, truncated (35-64 years) incidence rates to world population and crude incidence rate by site (ICD.9) did not reveal statistically significant decrease or increase in the incidence.

Hashimoto's thyroiditis: countrywide screening of goitrous healthy young girls in postiodization phase in India.

Countrywide salt iodization, to prevent nutritional iodine deficiency, has been achieved in India recently. The current study was planned to evaluate the prevalence of goiter and thyroid autoimmunity and assess thyroid functional status in a cohort of 6283 healthy schoolgirls from different parts of the country in the postiodization phase. Goitrous girls (n = 1810; 28% of subjects) were investigated for serum T4 and TSH, antithyroid microsomal antibody (TMA) and antithyroglobulin antibody (TGA), urinary iodine excretion, and cytomorphology by fine-needle aspiration cytology (FNAC). FNAC carried out successfully in 764 goitrous girls revealed juvenile autoimmune thyroiditis (JAT) in 58 (7.5%), which included Hashimoto's thyroiditis in 43 (5.6%) and focal lymphocytic thyroiditis in 15 (1.9%). TMA and TGA estimated in 722 goitrous girls detected significantly positive titers of TMA (> or =1:1600) and TGA (> or =1:160) in 52 (7.2%) and 4 (0.55%) girls, respectively. Only 29 (67.4%) girls with Hashimoto's thyroiditis were TMA positive. In patients with FNAC-proven JAT, overt clinical and biochemical hypothyroidism was seen in three (6.5%) and subclinical hypothyroidism in seven (15%). Subclinical hyperthyroidism was detected in 5.1% cases of JAT, and none had overt hyperthyroidism. No definite correlation was seen between urinary iodine excretion and thyroid autoimmunity.

Percussion of Traube's space--a useful index of splenic enlargement.

OBJECTIVE: To evaluate the sensitivity and specificity of palpation and percussion for splenic enlargement, as the accuracy of many of the clinical maneuvers we perform remains largely unstudied. METHODS: One hundred cases were selected at random from medical wards, and splenic enlargement was assessed by palpation and percussion of the Traube's space (Barkuns method), which was confirmed by the ultrasonography of the abdomen. The results of the various tests were tabulated and assessed statistically. RESULTS: 1) Performance of Traube's space percussion shows 24 true positive and 48 true negative cases, the test thus had an overall sensitivity of 67% and specificity of 75%. It was also found that the BMI of the false negative cases was significantly higher (29.43 Kg/m2). 2) Palpation as a diagnostic maneuver had a high specificity of 96.87% along with high false negative rate with overall low sensitivity of 44.44%. 3) Interpolation of findings of Traube's space percussion and palpation showed that maximum clinical utility could be achieved when both percussion and palpation were positive. CONCLUSION: Percussion of the Traube's space is a useful clinical screening test for splenomegaly, with a sensitivity of 67% and specificity of 75%, as compared to palpation (sensitivity of 44.44% and specificity of 96.87%). And maximum clinical utility is achieved when both percussion and palpation are combined.

Diabetic autonomic neuropathy causing gall bladder dysfunction.

OBJECTIVE: The objective of the study was to study gall bladder volume in fasting and 45 minutes post-prandial, by real time ultrasound in healthy controls and diabetic patients with and without autonomic neuropathy and to compare them. METHOD: Age, Sex and body mass index (BMI) matched 50 healthy subjects and 10 patients with insulin dependent diabetes mellitus and 40 patients with noninsulin dependent diabetes mellitus were evaluated according to National diabetes Data Group of National Institute of Health (1979) criteria: 1. Fasting (overnight) venous plasma glucose concentration of > 140 mg/dl on two separate occasions. 2. Following ingestion of 75 gms of glucose, venous plasma glucose concentration of > 200 mg/dl at second hour and at one other occasion during two hour test. Autonomic neuropathy was assessed by the presence of symptoms like dysphagia, abdominal fullness, nausea, vomiting, diarrhea +/- nocturnal, faecal incontinence or constipation, dysuria, urinary incontinence, the gustatory sweating, impotence etc. and were confirmed by standing test for orthostatic hypotension, hand grip test, Valsalva test and deep breaths test. RESULT: The study showed that: 1. Patients of diabetes mellitus had statistically significant larger fasting gall bladder volumes and these values were highly significant amongst patients with autonomic neuropathy. 2. Patients of diabetes mellitus and statistically significant larger post fatty meal gall bladder volume and these values were highly significant in patients with autonomic neuropathy. CONCLUSIONS: We therefore conclude that impaired gall bladder contraction was found amongst patients of diabetes mellitus with autonomic neuropathy. The mechanism responsible for cholecystoparesis is attributed to vagal neuropathy. Incomplete gall bladder emptying leads to sequestration of cholesterol and nidus formation. Therefore gall bladder functions should be evaluated routinely in such patients and early intervention is recommended.

Wilms' tumor. Role of fine needle aspiration and DNA ploidy by image analysis in prognostication.

OBJECTIVE: To evaluate the utility of cytomorphologic features and DNA ploidy estimation in fine needle aspirates (FNAs), from Wilms' tumors for prognostication. STUDY DESIGN: Twenty-three cases of Wilms' tumor having FNA and follow-up data were selected. Cytomorphology was analyzed by two observers. DNA ploidy was determined in 19 cases by image cytometry by destaining Papanicolaou-stained slides and restaining with Feulgen stain. Various parameters and patient outcomes were compared, and statistical evaluation was done. RESULTS: Poor outcome (12/23 cases) was associated with age < 2 years (P = .01), severe pleomorphism of blastemal cells (4/23 cases, P < .05), very large nucleoli (5/23 cases, P = .075), atypical mitosis (6/23 cases, P = .032) and aneuploidy/tetraploidy of tumor cells (6/29 cases, P = .005). Term unfavorable cytology is proposed when a combination of severe pleomorphism, very large nucleoli and atypical mitosis is seen in FNA smears. Four Wilms' tumor FNAs were characterized as showing unfavorable cytology, and all had a poor outcome (P = .0351). Three of the six cases with aneuploid/tetraploid features also showed unfavorable cytology. CONCLUSION: Unfavorable cytology and aneuploidy/tetraploidy in FNA smears of Wilms' tumor are associated with a poor prognosis.

Cytologic diagnosis of Enterobius vermicularis eggs in an enterocutaneous fistula.

A middle-aged female underwent a laparotomy for suspected ovarian cancer and developed a discharging sinus in the right iliac fossa. Smears of the discharge showed helminthic eggs which were characterised as those of Enterobius Vermicularis. The possibility of an enterocutaneous fistula was suggested which was subsequently confirmed during a relook laparotomy.

Diagnostic challenge of lobular carcinoma on aspiration cytology.

Lobular carcinomas are among the most difficult to type correctly on aspiration cytology. The inherent cytologic traits such as small size and bland appearance of cells in scanty aspirates may lead to false-negative diagnoses. Due to the low incidence of this form of breast carcinoma, there are few studies solely on lobular carcinoma, and the cytomorphologic features are not well defined. To delineate the cytomorphologic features and to assess their utility in correctly typing an aspirate as lobular carcinoma, we undertook a retrospective review of fine-needle aspirates from 31 cases of lobular carcinoma. The cytologic features of monomorphic cells, with scant cytoplasm, central vesicular nuclei, and inconspicuous nucleoli were found most helpful in correct typing of the cases. Intracytoplasmic vacuoles, nuclear grooves, and "Indian-file" arrangement of cells were corroborating features. We postulate that a combination of cytologic features makes the diagnostic delineation of lobular carcinomas possible on aspiration cytology.

Neuritic Hansen's disease: an unusual presentation and a diagnostic challenge on fine-needle aspirate.

Fine-needle aspiration cytology is now routinely used in the diagnosis of cervical lumps. We report on a case of leprous neuritis which presented as a cervical swelling. A diagnosis of leprosy was suggested on the basis of globi within histiocytes. These histiocytes differed from those classically described in leprosy. Retrospective review demonstrated the presence of occasional nerve fragments, and some of these closely resembled granulomas. The possible close resemblance of this lesion to tuberculosis and a histiocytic proliferative disorder is highlighted. Recognition of nerve fragments along with histiocytes should suggest the diagnosis.

AFB staining in cytodiagnosis of tuberculosis without classical features: a comparison of Ziehl-Neelsen and fluorescent methods.

Fine needle aspirates (FNA) were obtained from lymph node and other sites in 250 suspected cases of tuberculosis. Twenty-four cases proved to be non-tubercular on FNA smears and served as negative controls. Of the smears obtained from the remaining 226 cases, 233 were classified into five groups based on cytomorphological features, i.e. presence of necrosis and granulomas, necrosis alone or acute inflammatory exudate (AIE) with or without granuloma. Cases with AIE alone formed the largest group (n = 123). Staining for AFB was done by Ziehl-Neelsen (ZN) and fluorescent methods in all 250 cases. A correlation of AFB positivity and its semiquantitative scoring (1+ to 3+) with the cytomorphological spectrum was done. Overall AFB positivity by ZN staining was 33.5% and by fluorescent staining 45.4%. When the two methods were combined, AFB positivity was 58.7%. Fluorescent staining was superior to the ZN stain in the presence of a low bacterial load as seen in smears with diagnostic cytomorphological features of tuberculosis. In problem areas like AIE alone or with occasional granulomas, AFB positivity by ZN staining is nearly as good as the fluorescent method, because the bacterial load is high.

Fine needle aspiration (FNA) cytology of Rosai Dorfman disease.

Rosai Dorfman disease (sinus histiocytosis with massive lymphadenopathy (SHML)) is a benign self-limiting disorder that commonly involves the lymph nodes. We reviewed eight cases of this entity aiming to document the cytomorphological features. Of the eight cases, a preoperative diagnosis was suggested in seven cases. Pertinent features included: numerous large histiocytes with prominent emperipolesis (documented by a halo around the cell), fine vacuoles in the cytoplasm and lymphocytes and plasma cells in the background. In some cases the histiocytes showed atypia. In one biopsy-proven case a diagnosis of Hodgkin's was suggested, emphasizing the pitfalls associated with the FNA diagnosis of this lesion.

Characterization of tubular adenoma of breast--diagnostic problem in fine needle aspirates (FNAs).

FNA smears from six histologically documented cases of tubular adenoma of breast were critically analysed and compared with 10 histologically confirmed cases of fibroadenoma (five pericanalicular and five intracanalicular). Initially a cytological diagnosis of tubular adenoma was rendered only in one case. On review, two cases could be characterized as tubular adenoma, while the findings were suggestive in two others. The features helpful in diagnosis of tubular adenoma were the presence of benign ductal cells as three-dimensional cohesive balls and tubular structures in highly cellular smears. Stroma was conspicuously scanty or absent. Myoepithelial cells were present along with sheets of ductal cells as well as bipolar naked nuclei. Confusion with fibroadenoma occurred in two cases due to presence of a stag-horn pattern of ductal cells.
