RESUMEN

INTRODUCTION: Laparoscopic hernia repairs have been proven to be efficient and safe for children, despite the slightly higher recurrence rate compared with the classic surgical repair. They have the advantage of easy and precise identification of the type of defect and its correction, both in ipsilateral and contralateral sides. OBJECTIVES: The objectives of this study were to evaluate the efficacy, safety and outcome of the laparoscopically assisted piecemeal high ligation of a patent processus vaginalis (PPV) in children. METHODS: A total of 40 children were enrolled into this prospective study; they were aged ≥ 6 months and had an inguinal hernia. The peritoneal cavity, including the contralateral side, was inspected for the possibility of bilateral hernias using a 3-mm 30° telescope. Another 3-mm port was introduced through the same infra-umbilical incision. The hernia was manually reduced or with the aid of a working infra-umbilical grasper. A prolene or vicryl 2/0 or 3/0 suture on a curved semicircle round-bodied taper-ended 25-30 mm needle was introduced through a very small inguinal skin-crease incision. It was passed through the abdominal wall layers to the peritoneum and was manipulated by the laparoscopic grasper to pick up the peritoneum in piecemeal all around the internal ring. The needle was then pushed to the outside near to the entrance site, thus forming a semicircle around the internal ring. The suture was then tied and the knot was subcutaneously buried. The primary outcome of the procedure was the incidence of intraoperative diagnosis and surgical repair of contralateral hernias in pre-operatively diagnosed unilateral cases. The secondary outcomes were defined as the incidence of complications and hernia recurrence. DISCUSSION: The exploratory laparoscopy found contralateral patent processus vaginalis (CPPV) with a detection rate of 28.1%. Chan et al., Esposito et al., Toufique et al. and Niyogi et al. reported similar figures for laparoscopic contralateral hernia detection rates of 28%, 39%, 39.7% and 29.2%, respectively. The limitations of this study were the small sample size, plus the risk factors and clinical significance for CPPV. CONCLUSION: Laparascopically assisted piecemeal closure of the internal inguinal ring in children is a safe and effective procedure. It helps in detecting a contralateral hernia without prolonging the operative time.

RESUMEN

OBJECTIVES: To compare surgical outcomes and donor site complications of buccal and lingual mucosa used as ventral onlay graft for complex hypospadias cases. PATIENTS & METHODS: Forty four cases with complex hypospadias after failed previous surgery were prospectively included. All had severely scarred penile skin with reasonable residual urethral plate. Cases were categorized into two groups: Group I (23) where buccal mucosal graft [BMG] was used and group II (21) where lingual mucosal graft [LMG] was used. Donor site complications as well as functional and esthetic outcomes were recorded for each group. RESULTS: Mean follow up was 20.8 months (range 12-24). Average graft harvesting time was 24 min for BMG and 19 min for LMG. Donor site pain was reported with both techniques but recovery was earlier with LMG. Slurred speech and difficult tongue protrusion were reported with lingual but not buccal grafts; however mouth tightness, peri-oral numbness and persistent oral discomfort were reported only with buccal grafts. Successful urethroplasty was obtained in 78.2% of BMG compared to 76.1% of LMG. CONCLUSION: Surgical outcomes of LMG urethroplasty were comparable to those of BMG in complex hypospadias cases. Compared to buccal mucosa, LMG is easy to harvest, with minimal donor site complications.

RESUMEN

Objective To evaluate prospectively our experience using tubularized incised plate (TIP) urethroplasty in primary and repeat penile shaft hypospadias. Patients and Methods Thirty-two boys with penile shaft hypospadias were selected to undergo TIP procedure. Their age ranged from 22 months to 9 years. Twenty-two cases were primary and 10 cases were repeat hypospadias repairs. To correct penile chordee; complete degloving of the penis and lateral dissection of tethering tissues was done in every case. This was followed by tunica albuginea plication in 7 cases; while ellipse excision was needed in 3 cases. Using the preserved urethral plate; single-layer urethroplasty was done in all cases. A vascularized subcutaneous flap (36 cases) or tunica vaginalis (4 cases) was always used to cover the neourethra. A postoperative stent was used for 8 - 12 days in all cases. Results The patients were followed up for a mean of 14.2 months. Postoperative clinical evaluation revealed success rates of 95.5and 90for primary and repeat cases; respectively. Among the primary cases; only one patient had urethro-cutaneous fistula concomitant with meatal stenosis; while among the repeat cases urethro-cutaneous fistula occurred in one patient. No case of urethral stricture or wound dehiscence was encountered. Our criteria for success were a single unimpeded forward-directed urine stream; a straight penis; good cosmesis and no need for further surgery. Conclusion We feel that TIP urethroplasty in primary and repeat cases of penile hypospadias is a reasonable option in cases with chordee not severe enough to necessitate excision of the urethral plate and when midline incision of the plate yields an adequate width amenable to tubularization

RESUMEN

OBJECTIVE: Fever is the most common cause of convulsions, in infancy and childhood. Parents usually are concerned by the risk of recurrence. Our aim is to determine this risk of subsequent convulsions within the first year of the first episode of convulsion. METHODS: This is a prospective study over one year, May 97 to April 98 in which all children with first febrile seizure were enrolled. RESULTS: There were two hundred and thirty six children who had their first febrile convulsion within the study period. Male-to-female ratio was 1.2:1; the mean age at onset was 19 months (standard deviation 14.4). Generalized seizure occurred in 95.6% of the patients with an average duration of 7 minutes (SD 6.4). Ten percent of patients needed anticonvulsant drugs to stop convulsion. Seizure clusters occurred in 13.6 %, and complex febrile seizure was noticed in 21%. Family history was positive for epilepsy in 6.6% and febrile convulsions in 22%. Recurrence within a year from onset occurred in 52 (21%) of the patients. Factors associated with recurrence were: male sex, as male to female ratio was 2.25:1 (P = 0.02) and history of seizure clusters, 23/52, 44% (P = 0.00001). CONCLUSION: Risk factors for recurrence noted were male sex, and complex febrile seizures.

RESUMEN

To determine if the cell mediated immunity, induced by T-helper type-1 lymphocytes (Th1) response, during schistosomiasis mansoni has the potential to protect against infection, intensities of infections and re-infections, reflected in the egg count were followed up to 20 months among 119 individuals aged 5-22 years (Ys) with different number of previous infections whose yearly levels and pattern of water contact were similar. They were classified into 5 groups. Delayed hypersensitivity skin tests (DHT) to adult schistosome excretory-secretary antigens (ESAgs) and anti-schistosomula (ESAgs) isotypes were measured on detecting re-infection. The group with a mean age of (8.6 +/- 2.6 Ys) and infected less than 5 times showed only 6.5 percentage reduction of the egg count (PREC) and low cellular and humoral responses. Th1-associated cellular (DHT) and antibody responses (IgG2, IgG3) to the five infections were significantly higher in the (13.5 +/- 1.4 Ys) than in (18 +/- 2.2 Ys) age group. This was reflected in significant difference in PREC; being 41.5% among the first and 13.5% among the second. Th2-associated antibody responses (IgG1, IgG4, IgE) went on rising as patients allowed for age and number of infections increased over 5, being significantly higher in the (19 +/- 1.8 Ys) than in (14 +/- 1.1 Ys) age groups with PREC 45.5% and 12.9% respectively. These results imply a substantial protective role for cell mediated immunity in the pre-puberty stage and provide evidence that Th1-based vaccination strategy can work if augmented.

RESUMEN

Ancylostoma caninum is responsible for cases with eosinophilic enteritis (EE) and unexplained abdominal pain with peripheral eosinophilia in man. Ninety-five patients with obscure acute or recurrent abdominal pain and ten asymptomatic healthy parasite free were subjected to thorough history taking, clinical examination, sonography, routine laboratory investigations and serotesting by IgG ELISA to detect antibodies to excretory/secretory (ES) antigens of adult A. caninum and by IgG and IgG4 Western blot (W.B.) to detect antibodies to Ac68 antigen. Eleven male patients (11.6%) (5 with acute abdomen, 3 diagnosed as appendicitis and 3 had recurrent mild to moderate abdominal pain) fulfilled the criteria of case definition of human enteric infection with A. caninum (G.I). The study also detected human hookworm infection in 14 patients (G.IIb) other parasites in 34 patients (GIIc) and 36 patients had no parasites (G.IIa). Although 3 patients from group I were diagnosed as appendicitis and were dealt with surgically, the pain recurred and mebendazole only put an end to the patient's complaints. The obtained appendices of these operated cases showed marked eosinophilic infiltration but no adult canine hookworms were detected. IgG ELISA was positive in 72.7%, 8.3%, 100%, 23.5% and 0% in groups and control respectively. IgG and IgG4 W.B. did not increase the sensitivity but IgG4 W.B. elevated specificity to 100% excluding those with HH infection (Group Iib) who showed 100% cross-reactions. Stool analysis was the only differentiation between these two types of hookworms. These findings confirmed the presence of human enteric infection with A. caninum as clinical entity in the study community and referred to its value in differential diagnosis of the obscure abdominal pain.
