RESUMEN
BACKGROUND AND PURPOSE: To compare the rates of clinically relevant information provided by electroencephalogram (EEG) and magnetic resonance imaging (MRI) brain in first afebrile seizure (FAS) in children. METHODS: In this prospective randomized controlled trial, neurologically normal children between the age of 2 and 14 years, presenting with first episode of unprovoked, afebrile generalized or partial seizures, were included. Enrolled patients were randomized into two groups. After stabilization, initial workup and management, group I-patients underwent an EEG followed by MRI, whereas group II-patients underwent an initial MRI brain followed by an EEG. The patients were followed up after results of both the investigations and then every 3 months for seizure recurrence. The primary outcome was the proportion of investigations, providing clinically relevant information. The secondary outcomes were to determine the etiological diagnosis of FAS and record adverse events associated with EEG and MRI. RESULTS: Out of 170 enrolled patients, 52 patients (61.2%) in initial EEG group and 53 patients (70.6%) in initial MRI group had abnormal results on first investigation. An etiological diagnosis could not be made in any patient in initial EEG group. Neuroimaging revealed an etiological diagnosis in 53 patients (70.6%) in initial MRI group. Inflammatory granuloma was found to be the most common cause of FAS, followed by idiopathic epilepsy. CONCLUSIONS: The results of our study done in neurologically normal children with FAS showed a high diagnostic yield with an initial MRI. We recommend MRI brain to be considered as the initial investigation for evaluation of FAS in children.
RESUMEN
Acute appendicitis is one of the commonest surgical emergencies worldwide. There is considerable variation in prevalence of appendicoliths with appendicitis. Most of the patients with appendicoliths are asymptomatic and they are not pathognomic for acute appendicitis. However, appendicoliths show increased association with perforation and abscess formation. Appendicolith are quite common, being present in 3% of general population and in nearly 10% cases of appendicitis. However, giant appendicoliths measuring over 2 centimeters (cms) are extremely rare. Computed Tomography (CT) has increased their pre-operative diagnosis considerably. Use of spectral analysis can give us the details of composition of the stone pre-operatively. We present a young male diagnosed pre-operatively on Non-Contrast Computed Tomography (NCCT) to have a giant calcium struvite appendicolith. On laparoscopy he had a 3 cm stone and an incidental Meckel's diverticulum and underwent appendectomy. The case is presented for the unique size of the appendicolith alongwith review of literature.
RESUMEN
Inguinal hernia with vermiform appendix as content is known as Amyand's hernia. It is a rare entity but we encountered four cases within six months. A 52-year-old female had high grade fever and evidence of inflammatory pathology involving the ileocaecal region. She was initially managed conservatively and subsequently underwent exploratory laparatomy. The appendix was perforated and herniating in the inguinal canal. Appendectomy was done with herniorrhaphy without mesh placement. A 74-year-old male with bilateral inguinal hernia, of which, the right side was more symptomatic, underwent open exploration. Operative findings revealed a lipoma of the sac and a normal appearing appendix as content. Contents were reduced without appendectomy and mesh hernioplasty was performed. A 63-year-old male with an obstructed right sided hernia underwent emergency inguinal exploration which revealed edematous caecum and appendix as content without any inflammation. Contents were reduced without any resection. Herniorrhaphy was performed without mesh placement. A 66-year-old male with an uncomplicated right inguinal hernia underwent elective surgery. The sac revealed an appendix with adhesions at the neck. Contents were reduced after adhesiolysis and hernioplasty was performed with mesh placement. Emphasis is made to the rarity of disease, variation in presentation, and difference in treatment modalities depending upon the state of appendix.
RESUMEN
This report highlights that pleural and peritoneal mesothelioma can occur without direct asbestos exposure as was seen in our young patient. The patient had indirect exposure for as short as 3 months as a child, 15 years earlier, when she was residing with her miner father in the district of Jharia, Jharkhand, which is an asbestos-rich mining area in eastern India. The patient presented with chest pain and breathlessness. Chest X-ray showed opaque right hemithorax. Typical contrast- computed tomography (CECT) enhanced radiological features included nodular, soft-tissue attenuation and homogenously enhancing rind-like mass causing scalloping of the underlying lung and liver. Similar lesions were also found involving the pelvis. Diagnosis of malignant mesothelioma was confirmed on lung biopsy. Under-reporting of exposure is usual because it is unrecognized by both patients and investigators.
RESUMEN
Malignant melanoma of the rectum is an extremely rare disease. It typically presents in the fifth or sixth decade of life with nonspecific complaints such as rectal bleeding or anal pain. A timely diagnosis of anal melanoma is made even more difficult by the fact that most of the lesions lack obvious pigmentation and are even histologically amelanotic. Prognosis is very poor. Anorectal malignant melanomas spread along submucosal planes and are often beyond complete resection at the time of diagnosis. We present the radiological and pathological features seen in a 43-year-old woman diagnosed with melanoma of the rectum.
RESUMEN
Pediatric Spontaneous Bile duct perforation is a rare clinical condition with only around 150 cases reported worldwide. Early management gives excellent prognosis but the condition often presents a diagnostic dilemma. Hepato-biliary Technetium-99m-iminodiacetic acid scintiscan is the diagnostic investigation of choice but its availability in third world countries is limited. We present two cases of spontaneous biliary peritonitis in children, which were diagnosed without scintiscanning. The first case was a one-and -a half-year-old child, who was diagnosed with biliary peritonitis without pneumoperitoneum by a combination of Ultrasound (USG), Contrast enhanced computed tomography (CECT), and Magnetic Resonance Imaging (MRI). The child underwent USG-guided drainage and subsequent cholecystectomy with hepatico-jejunostomy. The second child also had biliary peritonitis without pneumoperitoneum, which was initially suspected on USG. CECT revealed dilated gall bladder and fluid collection in sub-hepatic space and pelvis. Abdominal paracentesis revealed presence of bile. The child responded to conservative therapy. Both are doing well on two-year follow-up. In a patient with jaundice, biliary tract abnormalities and/or free fluid, either generalized or localized to peri-cholecystic/sub-hepatic space on USG/CT/MRI, in the absence of pneumoperitoneum, suggest a diagnosis of biliary perforation even in the absence of scintiscanning.
RESUMEN
Gastrointestinal stromal tumors or "GIST" are mesenchymal neoplasms expressing KIT(CD117) tyrosine kinase and showing the presence of activating mutations in KIT or PDGFR α (platelet-derived growth factor alpha). GIST of anal canal is an extremely rare tumor, accounting for only 3% of all anorectal mesenchymal tumors and 0.1-0.4% of all GIST. GIST with large tumor size and high mitotic activity are highly malignant, but the biological behavior of anorectal GIST is less clear. Abdominoperineal resection (APR) or conservative surgery is the best treatment option. Imatinib mesylate, a tyrosine kinase inhibitor, has shown promising results in its management. We present a case of anorectal GIST diagnosed by computed tomography (CT) scan, magnetic resonance imaging (MRI), and colonoscopy with biopsy. The patient underwent abdominoperineal resection (APR) and was confirmed on histopathology to have anal canal GIST with tumor size more than 5 cm in maximum dimension and mitotic figures more than 5/50 high power field (HPF). The CD117-immunoreactive score-was 3+ in spindled cells. Therefore the patient was put on adjuvant imatinib mesylate 400 mg daily.
RESUMEN
A mass formed around a cotton matrix left within the body is termed as textiloma or gossypiboma. It is a rare complication of surgery most commonly seen after abdominal operations. The time of presentation may range from early post-operative period to several decades later. A correct diagnosis can be made in only one-third of the cases. The most common differential diagnosis is a new-onset or recurrent tumor. This may lead to a lot of patient anxiety as well as several unnecessary attempts at biopsy or surgery. Gossypiboma may present as either of the following syndromes - pseudotumoral, occlusive, or septic entity and the risk of fistulization increases with time. We present two diverse cases, the first case being of a patient with gastro-cutaneous fistula due to retained sponge presenting within 2 months of open cholecystectomy, while the second case presented 13 years after a hysterectomy, with abdominal lump and obstruction caused by a retained sponge.
RESUMEN
Adult intussusception is a rare entity accounting for only 5% of all intussusceptions and causes approximately 1% of all adult intestinal obstructions. Unlike paediatric intussusceptions which are usually idiopathic, there is usually a lead point pathology which might be malignant in up to 50% cases. We present an unusual case of adult intussusception which was not diagnosed on any investigation including computerized tomographic (CT) scan and magnetic resonance imaging (MRI). It was a case of ileo-ileo-cecal intussusception caused by a large lipoma 38 mm × 43 mm × 61 mm. It was treated by emergency laparotomy for acute intestinal obstruction. A conservative resection with ileostomy was performed with good postoperative recovery.
