Novel methodology for the follow-up of acute lymphoblastic leukemia using FTIR microspectroscopy

In this report, we present a novel spectroscopic method of follow-up during chemotherapy treatment for B- and T-cell childhood leukemia patients. We isolated peripheral lymphocytes from blood drawn from patients before and after the chemotherapy and collected Microscopic FTIR (FTIR-MC) spectra of the isolated lymphocytes. Our results showed that nucleic acids content decreased in both types of patients. Changes in phospholipids and proteins level could be observed. The overall effects of drugs administered to the patients can be understood at the molecular level using FTIR-MC and these results are expected to stimulate wider applications of spectroscopy in leukemia research.

Preduodenal portal vein causing duodenal obstruction associated with situs inversus, intestinal malrotation, and polysplenia: A case report

Preduodenal portal vein (PDPV) is a rare anomaly described in only 82 patients in the literature. In a few patients, the PDPV was the direct cause of duodenal obstruction. The authors have treated a newborn with PDPV associated with total situs inversus, intestinal malrotation and polysplenia who presented clinically with duodenal obstruction.

Peritoneal encapsulation: a rare cause of bowel obstruction in children

Two rare cases of peritoneal encapsulation causing partial intestinal obstruction are described. Both were operated on, and one of them had a "cocoonlike" appearance. The characteristics and differences of peritoneal encapsulation and abdominal cocoon are discussed.

Unusual presentation of omphalomesenteric duct remnant: a variant of mesodiverticular band causing intestinal obstruction

Two unusual cases of small bowel obstruction associated with an omphalomesenteric duct remnant are described in 2 girls aged 14 years. The causative factor was a stenotic area in the terminal ileum caused by a ringlike lipovascular mesenteric band encroaching externally on the lumen. A phytobezoar was lodged proximally. This is as yet an undescribed variant of a mesodiverticular band.

Lymphangioma circumscriptum

Two children with lymphangioma circumscriptum (LC), a rare cutaneous lymphangioma, are described. One was diagnosed antenatally as having a right axillary cystic hygroma; in addition, postnatally LC was noted on the right forearm. A few years later a mediastinal lymphangioma was diagnosed. This combination of LC associated with additional malformations of the lymphatic system has not been reported previously, and may point to a generalized developmental disorder of the lymphatic system. The pathophysiology of the lesion is discussed with a review of the pertinent literature. It appears that LC primarily affects the subcutaneous tissue in the form of cystic dilatation of lymphatic channels without systemic lymphatic communication. The skin lesions are probably secondary to the increased intraluminal pressure. The typical clinical appearance is manifested by multiple skin vesicles and lymphorrhea. The main treatment modality is surgical excision. Recurrences are not unusual and require re-excision.

Cyanotic limb in a newborn: a peculiar presentation of septic hip

A 12-day-old infant presented with marked cyanosis of the right lower limb, mimicking vascular compromise. Physical examination, plain radiography, and laboratory evidence of systemic infection suggested septic arthritis of the hip. Pyoarthrosis was verified by needle aspiration and open drainage. Streptococcus pneumoniae was isolated. A cyanotic limb may be an atypical presentation for septic arthritis in the newborn.

Necrotizing fasciitis and myonecrosis in early childhood: a report of three patients

Necrotizing fasciitis (NF) is a rare and life-threatening disease. It usually presents as a postoperative complication, but rarely appears following trauma or without apparent cause. Over a period of 2 years we have treated three infants with NF, aged 15, 5, and 30 months, respectively. Two patients developed this complication following minor trauma while the third was post-elective bilateral inguinal hernia repair. The micro-organisms isolated were Staphylococcus aureus with Enterococcus durans in one patient, beta-hemolytic streptococcus in a second, and Staph. aureus in the third. The cornerstone of therapy is prompt, early, aggressive surgical debridement of the massive necrotic tissue and repeated debridement if necessary, with appropriate parenteral antibiotic therapy and hyperalimentation. All three patients survived. Early recognition of this life-threatening situation is mandatory in achieving survival.

Tracheal rupture after blunt chest trauma in a child

Blunt traumatic tracheal rupture is a life-threatening injury. The authors report on a 14-year-old boy who suffered such an injury in a road accident, underwent surgery immediately, and survived. The relevant literature is reviewed.

Isolated torsion of the fallopian tube in premenarcheal girls

The authors report on two premenarcheal girls, ages 4 and 13 years, with isolated torsion of the fallopian tube, an extremely rare condition. The fallopian tube was salvaged by detorsion in the younger girl, the first salvage described in the English literature on children. The mechanism of the isolated torsion and the clinical implications are discussed.

Transaxillary upper thoracic sympathectomy for primary palmar hyperhidrosis in children and adolescents

Primary palmar hyperhidrosis is part of a triad of palmar, plantar, and axillary hyperhidrosis of unknown etiology, affecting children, adolescents, and young adults. Sixty-seven children and young adolescents were operated on during a 10-year period. A total of 103 transaxillary upper thoracic sympathectomies (36 bilateral) were performed, with no mortality. The immediate postoperative course was uneventful in 90%; the other 10% had mostly minor problems. The average hospitalization period was 3 to 4 days. Total abolition of palmar sweating was achieved in all but two patients in whom some residual moisture remained. Long-term extreme satisfaction was reported by 64 of 67 patients (94%). One was moderately satisfied, and two were not satisfied because of excessive "compensatory" sweating elsewhere. Compensatory sweating of some degree was reported by 45% of patients but did not alter satisfaction. By further limiting ganglionectomy to just one ganglion (T2 or T3), compensatory sweating possibly may be reduced further. Early surgery for severe palmar hyperhidrosis will save a child many years of agony and social discomfort because all types of conservative therapy are ineffective and cause unnecessary delay. A limited transaxillary upper thoracic sympathectomy is presently the authors' preferred approach, although ablation via thoracoscopy should not be excluded as further experience is gained with this modality.

Torsion of uterine adnexa in neonates and children: a report of 20 cases

Twenty children under the age of 14 years with torsion of the uterine adnexa are discussed. Of the 14 postnatal cases, 8 were associated with additional ovarian pathology whereas in 6 cases the torsion was of normal uterine adnexa. Six additional cases had antenatal torsion with "pseudocyst" formation. All 14 postnatal cases presented as acute abdominal emergency requiring immediate surgery. Only 6 of the 14 had been correctly diagnosed preoperatively, the rest being mostly diagnosed as acute appendicitis. Sonographic studies can improve the preoperative diagnosis. Hemorrhagic necrosis of the adnexa (secondary to the torsion) was found in all cases except one, and necessitated adnexal resection. In only one case preservation of the adnexa was possible. Fixation of the contralateral ovary is recommended in cases of torsion of normal uterine adnexa. All six cases of antenatal torsion were diagnosed by routine ultrasonography during pregnancy between the 29th and 40th week of gestation. The "fluid-fluid" level sign is characteristic of this lesion. These neonates were born in no acute distress and were found to be completely asymptomatic. Hence, they did not require urgent surgery and underwent operation electively at the age of 2 weeks. Resection of the pseudocyst with fixation of the contralateral ovary is the treatment of choice in these cases.
