Lumbar puncture requirement in acute hemiparesis: Diagnosis of tuberculous meningitis after hemiparesis in a child

Background

Infections are an important acquired cause of cerebral arteriopathy. Tuberculous (TB) meningitis leading to infectious cerebral vasculopathy is a rare cause of acute hemiparesis.

Case report

A 14-year-old male patient was examined after acute hemiparesis developing within 1 day. Neurological examination revealed total hemiplegia on the left side. Brain MRI findings showed bilateral focal T2-weighted signal hyperintensity in the subcortical and deep white matter regions. There were also areas of restricted diffusion in the right basal ganglia. Although the father had a history of pulmonary TB, the patient had not been given TB prophylaxis because of PPD negativity. At lumbar puncture, opening cerebrospinal fluid (CSF) pressure was 50 cm/H20, CSF protein 66.9 mg/dL, and glucose 54 mg/dL (concurrent blood glucose 93 mg/dL); 170 polymorphonuclear leukocytes per cubic millimeter were present in CSF. Following tests for TB, treatment was started immediately with four anti-TB drugs. TB PCR of CSF and acid-fast bacteria (AFB) staining in gastric aspirate were positive. At clinical follow-up, the patient was able to walk with support at the end of the first month.

Conclusion

Various infectious agents have been reported as causes of cerebral vasculopathy. TB, which affects a significant number of patients worldwide, should be kept in mind in terms of cerebral vascular complications. Lumbar puncture is essential in order to diagnose TB meningitis.     

Childhood central nervous system tumors at MAHAK’s Pediatric Cancer Treatment and Research Center (MPCTRC), Tehran,Iran

Purpose

As central nervous system (CNS) tumors account for second most common childhood malignancies and the first cause of mortality in children with cancer, improving treatment modalities can lead to increase the health care of patients. In this study, we examined the prevalence of childhood brain tumors in patients who referred to MAHAK’s Pediatric Cancer Treatment and Research Center (MPCTRC) for treatment.

Methods

A retrospective review of all children less than 15 years old with a CNS histologically proven tumor, who presented to MPCTRC from April 2007 to April 2010, was performed. Data was analyzed by SPSS version 19 with Kolmogorov–Smirnov and Chi-square tests.

Results

There were 198 (124 boys) children eligible for the study. The majority of the tumors were infratentorial (n?=?134), and the rest were supratentorial (n?=?60) and spinal (n?=?4) cases. The median age was 6.11?±?3.65 years old. Medulloblastoma (n?=?66), low-grade glioma (n?=?52), and high-grade glioma (n?=?40) were the most common tumors. The mean duration of follow-up was 21 months. At the time of this analysis, there were 105 (53 %) children alive, 82 (41.4 %) deaths, and 11 (5.6 %) lost for follow-up. The survival rate was 51.68?±?5.22 %.

Conclusions

In contrast of high rate of death in this study, other general characteristics can serve as benchmark for improving our care for children with brain tumors in Iran.     

Bilateral double osteotomy in severe torsional malalignment syndrome: 16 years follow-up

Background

Torsional malalignment syndrome (TMS) is a well defined condition consisting of a combination of femoral antetorsion and tibial lateral torsion. The axis of knee motion is medially rotated. This may lead to patellofemoral malalignment with an increased Q angle and chondromalacia, patellar subluxation and dislocation. Conservative management is recommended in all but the most rare and severest cases. In these cases deformity correction requires osteotomies at two levels per limb.

Materials and methods

From 1987 to 2002 in our institution three patients underwent double femoral and tibial osteotomy for TMS bilateral correction (12 osteotomies). All patients were reviewed at mean follow-up of 16 years.

Results

At final follow-up no patients reported persistence of knee or hip pain. At clinical examination both lower limbs showed a normal axis and a normal patella anterior position. Pre-operative femoral version measurement showed an average hip internal rotation of 81.5° (range 80°–85°) and average hip external rotation of 27.2° (10°–40°). Thigh–foot angle measurement showed an average value of 38.6° (32°–45°). At final follow-up femoral version measurement showed an average hip internal rotation of 49° (range 45°–55°) and average hip internal rotation of 44.3° (20°–48°) (Figs. 1, 2, 3, 4, 5, 6). Thigh–foot angles measurement showed an average value of 21.6° (18°–24°) outward.

Conclusion

We recommend a clinical, radiographical and CT scan evaluation of all torsional deformity. In cases of significant deformity, internally rotating the tibia alone is not sufficient. Ipsilateral outward femoral and inward tibial osteotomies are our current recommendation for TMS, both performed at the same surgical setting.     

Clinical Correlates of the Anatomical Relationships of the Foramen Ovale: A Radioanatomical Study

Introduction Endonasal endoscopic transpterygoid approaches are commonly used techniques to access the infratemporal fossa and parapharyngeal space. Important endoscopic endonasal landmarks for the poststyloid parapharyngeal space, hence the internal carotid artery, include the mandibular nerve at the level of foramen ovale and the lateral pterygoid plate. This study aims to define the anatomical relationships of the foramen ovale, establishing its distance to other important anatomical landmarks such as the pterygoid process and columella. Methods Distances between the foramen ovale, foramen rotundum, and fixed anatomical landmarks like the columella and pterygoid process were measured using computed tomography (CT) scans and cadaveric dissections of the pterygopalatine and infratemporal fossae. Results The mean distances from the foramen ovale to columella and from the foramen rotundum to columella were found to be 9.15 cm and 7.09 cm, respectively. Analysis of radiologic measurements detected no statistically significant differences between sides or gender. Conclusions The pterygoid plates and V3 are prominent landmarks of the endonasal endoscopic approach to the infratemporal fossa and poststyloid parapharyngeal space. A better understanding of the endoscopic anatomy of the infratemporal fossa and awareness of the approximate distances and geometry among anatomical landmarks facilitates a safe and complete resection of lesions arising or extending to these regions.     

Giant Inguinoscrotal Hernia—Report of a Rare Case With Literature Review

Massive inguinoscrotal hernias extending below the midpoint of the inner thigh, in the standing position constitute giant inguinoscrotal hernias. We report a patient who presented with giant right inguinal hernia with bilateral hydrocele for 25 years. He had no cardiorespiratory illnesses. He was taken up for surgery under general anesthesia after preoperative respiratory exercises. Sliding hernia with entire greater omentum, small bowel, and appendix as contents was identified. Meshplasty after omentectomy with bilateral subtotal excision of sac, right orchidectomy, and scrotoplasty were done. Giant inguinoscrotal hernias pose significant problems while replacing bowel contents because of the increase in intraabdominal and intrathoracic pressures. Recurrence is another complication seen after successful surgical management. Various techniques such as preoperative pneumoperitoneum, debulking abdominal contents with extensive bowel resections, or omentectomy and phrenectomy have been tried. Postoperative elective ventilation is also needed in many cases. We describe simple reduction with omentectomy as a viable technique in this patient. He did not need elective ventilation due to preoperative respiratory exercises and preparation and review of the literature.Key words: Debulking, Giant inguinoscrotal hernia, Massive inguinoscrotal hernia, Phrenectomy, VentilationGiant inguinoscrotal hernias are defined as those extending below the midpoint of the inner thigh, in the standing position.¹ These hernias are rare and usually the result of neglect or fear of surgical procedures and are prevalent in the rural population.² These massive hernias pose significant problems resulting from cardiorespiratory compromise following sudden increase in intra-abdominal pressure during replacement of herniated viscera.³ In order to circumvent these complications, techniques such as debulking, phrenectomy, and progressive pneumoperitoneum have been described.³ Here, we present a patient with giant inguinoscrotal hernia where simple reduction with omentectomy was successful, and we review the literature.     

Gossypiboma Presenting as Coloduodenal Fistula – Report of a Rare Case With Review of Literature

The term gossypiboma is used to describe a mass of cotton matrix left behind in a body cavity intraoperatively. The most common site reported is the abdominal cavity. It can present with abscess, intestinal obstruction, malabsorption, gastrointestinal hemorrhage, and fistulas. A 37-year-old woman presented with pain in the right hypochondrium for 2 months following open cholecystectomy. As she did not improve with proton pump inhibitors, an esophagogastroduodenoscopy (EGD) was done, which showed a possible gauze piece stained with bile in the first part of the duodenum. Contrast-enhanced computed tomography (CECT) of the abdomen revealed an abnormal fistulous communication of the first part of duodenum with proximal transverse colon, with a hypodense, mottled lesion within the lumen of the proximal transverse colon plugging the fistula, suggestive of a gossypiboma. Excision of the coloduodenal fistula, primary duodenal repair, and feeding jejunostomy was done. The patient recovered well and is now tolerating normal diet. Coloduodenal fistula is usually caused by Crohn''s disease, malignancy, right-sided diverticulitis, and gall stone disease. Isolated coloduodenal fistula due to gossypiboma has not been reported in the literature so far to the best of our knowledge. We report this case of coloduodenal fistula secondary to gossypiboma for its rarity and diagnostic challenge.Key words: Surgical sponges, Intestinal fistula, Multidetector computed tomographyThe first report of a coloduodenal fistula was by Haldane in 1862, and it was malignant from the hepatic flexure.¹ Coloduodenal fistula is caused by Crohn''s disease, malignancy, right-sided diverticulitis, and gall stone disease, but isolated coloduodenal fistula due to gossypiboma has not been reported in the literature to the best of our knowledge. Gossypiboma is known to present as intra-abdominal abscess, intestinal obstruction, and fistulization, but coloduodenal fistula has not been reported as a mode of presentation. We report this case of coloduodenal fistula secondary to gossypiboma for its rarity and diagnostic challenge.
