Rizwan Ahmad Khan; Shagufta Wahab; R. S. Chana; S. Naseem; S. Siddique

OBJECTIVE To study the clinicopathological profile of children from India with cervical lymphadenopathy and the role of fine-needle aspiration cytology with special emphasis on tuberculosis as a cause. METHODS A total of 89 children in the age group of 10 months to 12 years, presenting to our hospital from April 2004 to March 2005, were included. All the patients underwent thorough clinical and investigational assessment vis-à-vis cervical lymphadenopathy. Outcome measurements included clinical status and ability of conventional tests to categorize different types of lymphadenopathy and their utility in diagnosing tubercular lymphadenitis. Interobserver variability was analyzed measuring kappa test and was found to be in agreement. RESULTS Reactive hyperplasia was the most common type of lymphadenitis, followed by granulomatous involvement. Unilateral posterior triangle lymph nodes were the most commonly affected in the tubercular cervical lymphadenopathy group. Fine-needle aspiration followed by Ziehl-Neelsen staining, histopathology and culture in combination were able to perform the diagnosis in 85.7% of cases affected with tubercular etiology. CONCLUSIONS Fine-needle aspiration is a valuable diagnostic tool in the management of children with the clinical presentation of enlarged cervical lymph nodes. The technique reduces the need for more invasive and costly procedures, especially in a Third World country. Culture and histopathology, however, should be considered in cases where repeated fine-needle aspiration cytology is non-diagnostic.

OBJECTIVE To study the efficacy of fine-needle aspiration cytology (FNAC) of head and neck masses in pediatric patients. STUDY DESIGN Of the 128 cases studied, FNAC was performed in 74 patients and their cyto-histological correlation done. Sensitivity and specificity of cytological diagnosis was then computed. RESULTS Benign lesions were found to be more common than the malignant variety, the commonest being soft tissue tumors (46.87%). Lymphomas were the commonest tumors (22.6%) in the malignant category. Cytology was done in 74 patients of whom smears from 21 patients were unsatisfactory for diagnosis. There was one false positive and two false negative cases resulting in the specificity and sensitivity of FNAC in pediatric head and neck tumors to be 95.65% and 93.3% respectively. CONCLUSION FNAC is a useful and reliable tool in the diagnosis of head and neck masses with no contraindications and minimal complications even in children.

Rizwan Ahmad Khan; Shagufta Wahab; R. S. Chana; Rehan Fareed

Hydatidosis affects almost every region of the body. Although adults are mostly affected, children also suffer from the disease especially in endemic areas. The usual affected location is the liver, lung, spleen, brain, and kidney. We report a hydatid cyst located in a retroperitoneal location presenting with a sudden scrotal extension in a 7-year-old child. The finding presented a diagnostic dilemma vis-à-vis obstructed inguinal hernia.

Background and Aims: Fine needle aspiration cytology (FNAC) is a relatively new technique for the diagnosis of pediatric tumors. Most of the studies conducted so far have dealt only with malignant neoplasms or neoplasms of a particular organ/organ system in the pediatric population. Our work included a comprehensive study of both benign and malignant tumors in children younger than 15 years of age to correlate their clinical, cytological, and histological findings and to evaluate the effectiveness of FNAC in their diagnosis. Materials and Methods: We studied 588 cases over a period of ten years. Data was collected retrospectively as well as prospectively, and included all patients younger than 15 years of age, who presented with tumors or associated symptoms. Clinical, cytological, and histopathological correlations were done. Results: Benign soft tissue tumors formed the largest group among all pediatric tumors (41.5%). Lymphomas were the most common (25.1%) of all malignant tumors, followed closely by small round cell tumors (SRCTs, 21.3%). FNAC was performed in 342 (55.1%) cases, cyto-histological correlation was possible in 226 (38.4%) cases; and a concordant diagnosis was seen in 218 (37.1%) cases, giving an overall diagnostic accuracy of 96.46% with FNAC. Occasional rare cases like Dabskas tumor and intraabdominal desmoplastic small round cell tumor could also be diagnosed by FNAC. Conclusions: We conclude that FNAC is an effective method for the evaluation and screening of pediatric masses, as well as for follow-up of patients with a history of malignancy.

Cytodiagnosis of Yolk Sac Tumor

Nishat Afroz; Nazoora Khan; R. S. Chana

To analyze cytomorphologic features of yolk sac tumors of childhood. Four cases of pediatric yolk sac tumor (YST), diagnosed by Fine needle aspiration cytology were reviewed (1998–2002). Age of patients ranged from 11/2 to 5 years. Three cases presented clinically with an intra-abdominal mass while one case presented with a testicular mass. Fine needle aspirates had been obtained directly as well as under radiologic (USG/CT) guidance. Smears were stained with H & E and Papanicolaou stain. In all cases values of serum α-Fetoprotein and ΒhCG were available preoperatively. Histopathologic diagnosis was correlated with cytologie findings in all the cases. Cytologie examination showed richly cellular smears with a combination of morphological patterns. Characteristically, tumor cells were arranged in papillary groups, tight cell clusters and formed acinar structures. Cells showed enlarged, moderately pleomorphic, hyperchromatic nuclei and moderate amount of cytoplasm, some of which displayed cytoplasmic vacuolation, displacing the nuclei eccentrically. Preoperatively, serum α-fetoprotein level was raised in all cases. Histopathology confirmed the cytologie diagnosis. Yolk sac tumor is common among the germ cell tumors of pediatric age group which presents a spectrum of cytomorphologic features having important differences with other germ cell neoplasm,e.g. embryonal carcinoma. Clinicoradiologic features and tumor markers are additionally helpful for an accurate cytologie diagnosis.

Objectives: To evaluate the effect of parenteral testosterone on penile length, preputial skin and side effects in patients with hypospadias. Materials and Methods: 23 patients with hypospadias were included in this study. An oily solution, each ml of which contained testosterone propionate 25 mg, and testosterone enanthate 110 mg, equivalent to 100 mg of testosterone was given deep intramuscularly 4, 3 and 2 weeks before reconstructive surgery at the dose of 2 mg/kg body weight. Increase in penile length, transverse preputial diameter, and diameter at the base of penis were noted. Basal testosterone levels were obtained before the institution of therapy and on the day of operation. In addition, side effect such as development of pubic hair and delay in bone age was noted. Results: Following parenteral testosterone administration, the mean increase in penile length, transverse preputial diameter and diameter at the base of penis was 1.35±0.40 cm (P<0.001), 1.40±0.47 cm (P<0.001), and 0.72±0.47 cm (P<0.001), respectively. Serum testosterone level after injection was well within normal range for that age. Minimal side effects were noted in form of development of fine pubic hair. Conclusion: We conclude that parenteral testosterone can be safely used to improve the surgical outcome of hypospadias repair.

Background: EMLA cream (eutectic mixture of local anesthetics) has been shown to penetrate intact skin and provide analgesia of superficial layers. There are no studies on the effects of topical application of EMLA cream for postoperative pain relief after inguinal hernia repair. Objective: This randomized, double-blind, placebo-controlled study compared the efficacy of topical application of 5% EMLA cream before surgery, with wound infiltration with 1% lidocaine for postoperative analgesia in children. Methods: Ninety children, aged 4 to 12 years, undergoing elective inguinal hernia repair under general anesthesia were enrolled in the study. Patients were randomly assigned to receive either placebo cream (group1), 5% EMLA cream (group 2), or placebo cream followed by 0.5 mL/kg 1% lidocaine (group 3) in the wound after induction of anesthesia. The anesthetic technique and monitoring were standardized, and postoperative pain was assessed using a 10-point objective pain scale. Fentanyl was used as rescue analgesic in immediate postoperative period, and acetaminophen was administered for postoperative pain in surgical ward. Results: The number of patients requiring fentanyl in the immediate postoperative period was significantly less in the study groups compared with the placebo group. Sixty-seven percent of patients in the placebo group required more than 1 dose of acetaminophen in the first 6 hrs compared with 23% (EMLA group) and 20% (lidocaine group). Four patients (two in the lidocaine group, one in the EMLA group, and one in the control group) developed subcutaneous infection at the site of incision 10 to 15 days postoperatively. Conclusion: Topical application of EMLA (5%) provides postoperative analgesia comparable to infiltration with 1% lidocaine after inguinal hernia repair in children.

BACKGROUND The aims of this study have been elaborated below: (1) to enumerate the common causes of acute abdominal emergencies by ultrasonography in paediatric patients; (2) to establish the diagnostic efficacy of ultrasonography in evaluation of acute abdominal conditions in children and to illustrate the associated ultrasonographic findings; (3) and, to discuss the role of ultrasonography in guiding the mode of intervention in these cases. PATIENTS AND METHODS This prospective study of ultrasonographic examination in 146 paediatric patients presenting with acute onset abdominal pain at the emergency/paediatric outpatient department section of Jawaharlal Nehru Medical College & Hospital, Aligarh, between June 2006 and December 2007, using 3.75 MHz and 8 MHz transducers of the ADARA (Siemens) machine. RESULTS Common causes of acute abdominal emergencies in pediatric patients as noted on ultrasonography included nonspecific pain (28%), abdominal abscess (21%), acute appendicitis (7%) and intussusception (7%). Ultrasonography was diagnostic in 45.2% cases and supportive in 12.3% of the cases. As for as the final outcome, ultrasonography prevented surgery in almost 20% cases and laparotomy was avoided in 7% of the patients as ultrasound guided interventions in the form of abscess aspiration were carried out. CONCLUSION Ultrasonography evaluation of children with acute abdominal pain, helps in making significant changes in the management plan of the patients, and also reveals various clinically unsuspected diseases.
