The need for an epidural "window of opportunity" in pregnant women with a lumbar tattoo.

Pregnant women with lower back tattoos who wish to have an epidural placed during labour pose a dilemma to anesthesiologists. Clear guidelines have not been established. We reviewed the epidural risks in pregnant women with low back tattoos and have suggested precautionary measures to minimise them. Given the limited information available, and in the absence of a clear evidence-based medical contraindication, an epidural technique should not be excluded in those women with a lower back tattoo.

GnRH agonist for triggering final oocyte maturation in patients at risk of ovarian hyperstimulation syndrome: still a controversy?

PURPOSE: An update on the subject of ovarian hyperstimulation syndrome (OHSS) prevention with GnRH agonist ovulation trigger. METHODS: Review of pertinent English language studies published during the past 4 years. RESULTS: Randomized prospective studies support the notion that agonist trigger completely eliminates OHSS. Conflicting results regarding on going pregnancy rate probably reflect different approaches to luteal phase support. Embryos obtained and frozen after agonist trigger yield good clinical outcome in subsequent thaw cycles. CONCLUSIONS: The notion that agonist trigger can eliminate OHSS is strongly supported by randomized controlled trials. Further research is needed to assess optimal luteal support post agonist trigger.

[Analgesics-induced chronic renal failure in patients on dialysis therapy in Hungary]. / Analgetikum-nephropathia elófordulása krónikus veseelégtelenség miatt dializált betegekben Magyarországon.

In recent years elaboration of the diagnosis of analgesic-nephropathy (ANP) with the help of imaging techniques significantly increased the possibility of diagnosing the disease. Therefore, evaluating the prevalence of ANP has become more accurate in our country as well. The prevalence of ANP has been investigated in patients who have newly been taken into the dialysis program due to renal disease of unknown aetiology in 22 dialysis centers between December 1994-December 1997. The diagnosis of ANP has been based on revealing chronic drug abuse in the history and positive results of renal imaging (decrease in length of both kidneys combined with either bumpy contours and/or papillary calcification). Among 284 patients dialysed with unknown diagnosis 42 (14.8% of all cases) proved to have ANP. All patients except 2 took analgesic mixtures containing phenacetin/paracetamol, phenason derivatives, acetilsalysilic acid, caffeine and/or codeine. According to their investigations, ANP is a common disease resulting in end-stage renal failure in Hungary as well.

[Colonic pseudo-obstruction (Ogilvie syndrome) following cesarean section].

Acute colonic pseudo-obstruction, or Ogilvie syndrome can be a major surgical complication. Ogilvie syndrome, unlike adynamic ileus, is usually not self-limiting and may cause ischemic necrosis and colonic perforation, with a mortality rate as high as 50 percent. Ogilvie syndrome represents a diagnostic and therapeutic challenge that deserves a multidisciplinary approach. We present a case report and a literature review of the syndrome.

Variables associated with meconium aspiration syndrome in labors with thick meconium.

OBJECTIVE: To examine the possible maternal and fetal variables associated with meconium aspiration syndrome in labors with thick meconium. STUDY DESIGN: The fetal heart rate tracings, cord pH, Apgar scores and maternal risk factors were evaluated in singleton pregnancies with vertex presentation and thick meconium in labor. The study included 33 consecutive fetuses which developed a moderate or severe meconium aspiration syndrome and 104 consecutive fetuses which had a favorable outcome. RESULTS: Significant differences between fetuses with meconium aspiration syndrome and healthy fetuses were found in the following parameters: baseline FHR (154+/-17 vs. 136+/-10, P<0.0001), small accelerations/30 min (1.47+/-1.52 vs. 3.04+/-1.2, P<0.0001), large accelerations/30 min (1.46+/-1.96 vs. 3.5+/-2.31, P<0.0003), decelerations/30 min (4.9+/-3.9 vs. 2.4+/-2.1, P<0.0034), number of fetuses with reduced beat-to-beat variability (9/33 vs. 0/104, P<0.0001), cord pH (7.21+/-0.09 vs. 7.33+/-0.08, P<0.0013) and Apgar scores at 1 min (5+/-2 vs. 8+/-1, P<0.0001) and Apgar scores at 5 min (8+/-2 vs. 9.7+/-0.6, P<0.0001). Maternal risk factors were found in two of 33 sick infants and in 13 of 104 healthy infants. CONCLUSION: Thick meconium by itself is not associated with adverse fetal outcome. However, the incidence of meconium aspiration syndrome increases in cases of a non-reassuring FHR.

Oral analgesia in the treatment of post-cesarean pain.

OBJECTIVE: Cesarean section is one of the most common operations. The new technologies of postoperative pain treatment such as patient-controlled analgesia, are expensive and may limit women caring for their newborns shortly after delivery. The present study assessed patient satisfaction with oral analgesia following cesarean section. STUDY DESIGN: An open prospective study was conducted on all women who had a cesarean section with epidural analgesia, during two consecutive periods of 3 months each. In the first group of 109 women, an oral solution of 1 g dipyrone was allowed every 4 h, upon patient request. Patients requesting additional analgesia were administered a tablet of 30 mg immediate-release morphine sulfate. In the second group of 90 women, the same protocol was used; however, oral morphine was the drug of choice and dipyrone was used for rescue analgesia. Pain intensity and satisfaction were self-evaluated by patients using a visual analog scale. RESULTS: The results of each study period were independently evaluated. The demographic and obstetrical variables were similar in both groups. The duration of analgesic effect of dipyrone was 6.5 h and the satisfaction score was 90. The duration of analgesic effect of oral morphine was 5.05 h and the satisfaction score was 83.7. Overall, patients in both groups requested only 25% of the permissible dosage of analgesia. CONCLUSIONS: Oral analgesia following cesarean section provides satisfactory pain relief, is easily administered, and is a substantially less costly alternative to the new pain treatment technologies currently in use.

Comparing thyroid ultrasonography to thyroid function in long-term survivors of childhood lymphoma.

BACKGROUND: We studied the value of thyroid ultrasonography as a follow-up tool in survivors of childhood lymphomas and correlated morphologic abnormalities with thyroid function tests. PROCEDURE: A prospective follow-up study of 45 long-term survivors of histology-proved childhood lymphomas was performed. Mean age at diagnosis was 9.1 years (range 2.1-16.4 years) and mean follow-up duration 10.9 years (range 3.9-22.2 years). RESULTS: Among the 26 survivors of Hodgkin disease (HD) who received mantle field irradiation, 14 (54%) had abnormal ultrasonograms. Elevated thyroid-stimulating hormone (TSH) concentrations were found in 14 (54%), and 6 of them (42%) had normal thyroid functions. Six of twelve patients with normal ultrasonograms had abnormal thyroid function, and 5 of 11 patients with normal function had abnormal sonograms. Among the 19 non-HD survivors who did not receive radiotherapy, 18 (95%) had both normal sonograms and normal function. Thus thyroid gland abnormalities were detected in 54% of HD survivors after mantle field irradiation. No correlation between the abnormalities detected on ultrasonography and serum levels of TSH and thyroid hormones were found. CONCLUSIONS: Both ultrasound and thyroid function tests independently provide clinically useful information; the former examines gland morphologogy and the latter evaluates hormonal changes associated with thyroid disease. The high frequency of thyroid abnormalities detected by ultrasonography suggests that periodic thyroid ultrasonography is advisable in the follow-up of patients treated with mantle irradiation to screen for morphologic changes that may presage malignant transformation.

Male gonadal function in survivors of childhood Hodgkin and non-Hodgkin lymphoma.

The aim of this study was to investigate the impact of therapy on long-term gonadal function of young people cured of childhood lymphomas and to assess whether a prepubertal state during the treatment protects the gonads from chemotherapy and/or radiotherapy late effects. Clinical evaluation, semen analysis, and endocrine status were studied in 20 survivors of childhood lymphomas. Five patients received Inverted Y radiotherapy, 2320 cGy (1550-4000); all 20 received chemotherapy as follows: MOPP/ABVD protocol, 9 patients; COMP protocol, 5 patients; MOPP protocol, 3 patients; other protocols, 3 patients. Semen analysis results were as follows: normal values, 4/20 patients; oligospermia, 8/20 patients; azoospermia, 8/20 patients; FSH above normal level, 10/20 patients; 4/5 who received Inverted Y irradiation were azoospermic and 1 was severely oligospermic. Treatment damage to the testis involves tubular germinal elements. Radiotherapy and chemotherapy combinations that included nitrogen mustard or cyclophosphamide were associated with high rates of oligospermia and azoospermia. MOPP/ABVD combination did not have a significant better outcome of sperm counts compared to MOPP alone. Age at chemotherapy did not correlate with the sperm count; hence a prepubertal state did not protect the gonad from the late effects of treatment.

Adverse effects of epidural analgesia in labor.

OBJECTIVE: To examine the influence of epidural analgesia on labor and delivery in nulliparous and multiparous women. DESIGN: Data were collected on 847 consecutive parturients with singleton pregnancy and vertex presentation (384 nulliparous and 463 multiparous). The obstetrical and labor characteristics including maternal age, parity, gestational age, previous cesarean section, instrumental delivery, mode and timing of analgesia, mode of delivery, indications for cesarean section or instrumental delivery were analyzed comparing patients who received epidural analgesia with women who received systemic analgesia. RESULTS: Epidural analgesia was administered in 233 nulliparous and 141 multiparous women. A stepwise logistic regression analysis revealed that epidural analgesia independently affected the rate of non-spontaneous delivery and the duration of the second stage of labor in nulliparous (P=0.0017 and P=0.0036, respectively) and multiparous (P=0.001 and P=0.0081, respectively) women. Epidural analgesia independently affected the duration of labor only in nulliparous women (P=0.0001). CONCLUSION: Women should be informed that prolongation of labor and increase in nonspontaneous deliveries should be expected when choosing epidural analgesia in labor.

[Self-limited lymphadenopathy mimicking lymphoma or lupus (Kikuchi-Fujimoto disease)].

Kikuchi-Fujimoto disease in a self-limited lymphadenopathy that can be confused histologically and clinically with lymphoma or systemic lupus erythematosus. It was diagnosed in a 37-year-old woman presenting with fever, cervical, submandibular and axillary lymphadenopathy, weight loss and recurrent urinary tract infections. Lymph node biopsy was consistent with the diagnosis of a histiocytic necrotizing lymphadenitis. Early diagnosis of Kikuchi-Fujimoto disease can prevent harmful treatment.

[Endoscopic ligation of bleeding esophageal varices]. / Vérzö nyelöcsövarixok endoscop segítségével történö leszorítása.

Endoscopic variceal ligation (EVL) is a new method for treating oesophageal varices, which was developed to reduce the high complication rate seen with endoscopic sclerotherapy. This technique consists of mechanical occlusion and thrombosis applying small elastic bands around the variceal channels in the distal oesophagus. We report 39 patients treated with EVL during the period from April 1995 to December 1996. The average age of patients was 50.1 years, 33 men, 6 women. Portal hypertension was caused by alcoholic liver disease in 36 patients. Seven patients died within 1 month. Varices were eradicated in 28 patients. Variceal eradication required an average of 3, 4 sessions. Active bleeding was controlled by EVL in 11 patients out of 12. Recurrent bleeding occurred in 14 out of 39 patients (35%). One oesophageal perforation occurred in connection with overtube placement. There were no other major complications. In conclusion EVL is an effective treatment for bleeding oesophageal varices.

Combined peritoneal and haemodialysis therapy for chronic renal insufficiency.

Twenty-three patients with chronic uraemia were treated for an average of 8.5 months with intermittent peritoneal dialysis. When hypervolaemia developed and/or the volume of low-molecular weight substances increased, the therapy was complemented by one or two sessions of haemodialysis per week. The combined treatment was carried on for 4.1 months on average, in consequence of which the general condition improved, body weight reached the optimum, blood pressure diminished, turned normal and could be controlled by drugs. In the wake of the therapy carbamide nitrogen and creatinine levels dropped significantly, serum total protein and albumin values increased. At the close of the observation period 3 patients remained under combined therapy, 2 had undergone cadaveric kidney transplantation, 18 were transferred to chronic haemodialysis. Thoughts are evolved about the advisability of intermittent peritoneal dialysis and combined therapy in the care for uraemic patients.

[Combination of peritoneal dialysis and hemodialysis in the treatment of chronic renal insufficiency]. / Peritonealis dialízis és haemodializis kombinációja a krónikus veseelégtelenség kezelésében.

In case of 23 patients, who had been treated for 8.5 (2-10) months with intermittent peritoneal dialysis, the peritoneal dialysis was supplemented once or twice a week by haemodialysis for 8.5 months. This combined way of treatment was favourable in cases of hypervolemia and/or of increased level of substances of small molecular weight. The average duration of this kind of treatment was 4.1 (1.5-11) months. In the course of treatment the general condition of the patients improved. When they regained their optimal bodyweight, their blood pressure got normalized or their hypertony decreased or it could be regulated by drug therapy. At the effect of this treatment, the carbamid nitrate and serum creatinin significantly decreased and the serum total protein and albumin levels increased. Two of the patients underwent cadaver kidney transplantation, and 18 of them have been treated by hemodialysis, 3 of them are being treated in this combined way even now. The authors discuss the role of intermittent peritoneal dialysis and that of the combined treatment in the management of uremic patients.

Treatment of duodenal ulcers by antacid (Al-Mg-hydroxy-carbonate). A controlled, randomized, prospective, multicentre clinical trial.

TISACID (a new, modern Hungarian Al-containing antacid) with a high acid-neutralizing capacity (greater than 26.8 mmol/g) also enhances gastric mucosal defense mechanisms (prostaglandin-dependent gastroprotection). A simple-blind, prospective, randomized, parallel multicentre clinical trial has been performed on both the clinical efficacy and possible side effects of TISACID monotherapy (Al-Mg-hydroxy-carbonate) on informed patients suffering from active duodenal ulcers. The study groups were as follows: Group "A": 3 g/day of TISACID (acid-neutralizing capacity = 78 mmol, n = 85), Group "B": 6 g/day of TISACID (acid-neutralizing capacity = 156 mmol, n = 88), Group "C": 12 g/day of TISACID (acid-neutralizing capacity = 312 mmol, n = 68), Group "D": (as control): (1.0 g/day cimetidine (HISTODIL, RGH, Budapest, n = 91). The total number of patients: 332. It was found that: 1. The new Hungarian antacid compound (both tablet and suspension) can essentially accelerate the healing rate of duodenal ulcers. 2. The cumulative healing rate of ulcers and the decrease of complaints can be achieved equally by relatively low doses of TISACID monotherapy and cimetidine alone. 3. There were no differences between the clinical potency and side-effects of TISACID tablet and suspension.

A controlled multicentre therapeutic trial to determine the efficacy of a novel antacid (AI-Mg-hydroxy-carbonate) in duodenal ulcer.

Tisacid (a new, modern Hungarian AI-containing antacid) with a high acid-neutralizing capacity (greater than 26.8 mmol/g) also enhances gastric mucosal defense mechanisms (prostaglandin-dependent gastroprotection). A simple-blind, prospective, randomized, parallel multicentre clinical trial has been performed on both the clinical efficacy and possible side-effects of Tisacid monotherapy (AI-Mg-hydroxy-carbonate) on informed patients suffering from active duodenal ulcers. The four study groups were as follows: Group A: 3 g/day of Tisacid (acid-neutralizing capacity = 78 mmol, n = 85), Group B: 6 g/day of Tisacid (acid-neutralizing capacity = 156 mmol, n = 88), Group C: 12 g/day of Tisacid (acid-neutralizing capacity = 312 mmol, n = 68), Group D (as control): 1.0 g/day cimetidine (n = 91). The total number of patients was 332. It was found that the new Hungarian antacid compound (both tablet and suspension) can essentially accelerate the healing rate of duodenal ulcers; the cumulative healing rate of ulcers and the decrease of complaints can be achieved equally by relatively low doses of Tisacid monotherapy and cimetidine alone; and there were no essential differences between the clinical potency and side-effects of Tisacid tablets or the suspension.
