[Abdominal gunshot wounds: retrospective analysis of 164 patients].
The medical reports of 164 patients who were operated for abdominal gunshot wounds at Sirnak Military hospital were reviewed retrospectively. One hundred and twenty-nine patients had isolated abdominal injury whereas, 28 had associated thoracic injuries. Seven of these laparotomies revealed no intraperitoneal injury and were considered as non-therapeutic laparotomy. The time for transportation to the emergency department were less than 2 hours in 69% of the patients. The most commonly injured organs were the small bowel in 67, the colon in 63 and the liver in 49 patients. Postoperative complications occurred in 34 patients (20.7%) and mortality rate was 6% (10 patients). In spite of the developing technology and operative techniques, gunshot wounds are still very important with high morbidity and mortality rates.

[Injuries of the extremities caused by high energy gunshots and land-mines].
Hospital records of patients who had extremity injuries caused by high energy gunshots and and land-mines and treated in Sirnak Military Hospital between January 1997 and July 1999 were reviewed retrospectively. Among 236 cases 147 (62.3%) had lower extremity wounds and 89 (37.7%) had upper extremity wounds. The most frequently injured part was hands for the upper extremity and feet for the lower extremity. The most dramatic wounds were caused by stepping on anti personnel mines trapped with anti tank mines. The localization and the extension of the wounds varies with type and power of the gun, the position of the victim at the time of explosion and the distance between the victim and the gun.

The effect of alternate-day low dose prednisolone on bone age in children with steroid dependent nephrotic syndrome.
Radius, ulna, short bones (RUS), carpal (CARP) bone age (BA), tibial cortico-diaphyseal (C/D) ratio and trabecular aspect were assessed in 19 children with steroid dependent nephrotic syndrome and 15 age matched healthy children. Both RUS and CARP BA were significantly lower than in the controls. Trabecular aspect and tibial C/D ratio did not show any statistical significance. There was a positive correlation between HSDS and RUS BA delay (r = -0.476, p < 0.05); CARP BA delay and RUS BA delay (r = 0.563, p < 0.01) and RUS BA and CARP BA (r = 0.891, p < 0.001). In conclusion, RUS and CARP BA are both retarded and positively correlated in steroid dependent nephrotic children.

The application of a double voltage modulation technique to a glow discharge source with a supplementary electrode.
The Ar spectral lines are suppressed in glow discharge source atomic emission spectroscopy by a double voltage modulation technique with a supplementary electrode. The voltage is modulated between two levels, typically 350 and 700 V. At the lower voltage level mainly the Ar emission occurs where at the higher voltage level both the Ar and the metal atoms sputtered from the sample contribute to the emission. The power supply of the supplementary electrode is switched on when the glow discharge passes from operation at 700 V to 350 V. The intensity of argon gase lines is regulated by the current applied to the supplementary electrode at that period. Therefore, there is no need for electronical amplification and lower voltage adjustment of two operation modes. This modified DVM technique has been applied to the determination of Si and Cu in Al- samples. The suppression of Ar lines is possible, and the elements can be determined without Ar interferences.

Ritodrine tocolysis and neonatal intraventricular-periventricular hemorrhage.
Betamimetic drugs are commonly used for tocolytic therapy. To determine their potential role in periventricular-intraventricular neonatal hemorrhage (IVH), 103 preterm births with cranial ultrasonography results were evaluated for the history of betamimetic therapy. The study group was divided into three subgroups according to the cause of the preterm delivery: 44 patients were accepted as tocolysis failure (group A); 53 patients were too late for tocolysis (group B), and these latter cases were taken as controls for group A; for the remaining 6 patients, tocolysis was contraindicated due to fetomaternal reasons (group C), and these cases were not included in the analysis. In group A, 32 patients got ritodrine, 6 patients got combined therapy including ritodrine plus magnesium sulfate or nifedipine. When cases in group A who got ritodrine only or combined therapy are compared with the no-treatment group, no significant difference in neonatal IVH incidences could be found (p > 0.005). Ritodrine does not appear to affect the incidence of neonatal IVH.

Organochlorine pesticide residues in human milk in Kayseri.
In this study: dichlorodiphenyltrichloroethane (DDT) and its metabolites [DDT + dichlorodiphenyl-dichloroethylene (DDE)], BHC (HCH) and their main isomers such as alpha, beta, gamma BHC, aldrin and its metabolite dieldrin, heptachloride, heptachloride epoxide, were investigated in 51 samples of breast milk of 51 lactating women during 1988. The ages of the mothers, who were working in agriculture, ranged from 17 to 33 y (mean 24.2 y). The concentrations of hexachlorobenzene (HCB), alpha BHC, beta BHC, gamma BHC, heptachloride, aldrin, heptachloride epoxide, pp'DDE, dieldrin, op'DDT, pp'DDT were found as 84 +/- 23, 96 +/- 20, 522 +/- 120, 156 +/- 20, 198 +/- 130, 47 +/- 9, 11 +/- 4, 2389 +/- 280, 6.7 +/- 3, 70 +/- 12, 410 +/- 60 micrograms kg-1 milk, fat, respectively, measured by gas chromatography (GC) method. The concentrations of chlorinated pesticides in human milk samples from Kayseri were compared with similar data obtained from other countries. The amounts of total BHC and aldrin derivatives were below the acceptable daily intake (ADI), whereas the amount of total DDT derivates was above, of the World Health Organization (WHO).

Pendred's syndrome.
Although 5% of all cases of congenital deafness are caused by Pendred's syndrome, there are few reports in the literature. Seven patients with Pendred's syndrome in three families living in the same village were detected. For that reason, the syndrome is reviewed in light of the literature. The sex distribution of the patients with Pendred's syndrome and their families was recorded. We tested for thyroxine, triiodothyronine, thyroid-stimulating hormone, triiodothyronine resin uptake, and perchlorate, and performed caloric testing. In one patient, subtotal thyroidectomy was performed. In the histopathologic study, a thyroid nodule filled with colloid was found. Chromosome studies showed no anomalies in any patient. Five of the patients were deaf-mutes. We observed that the parents were cousins in all three families. These families also had healthy children, and the existence of the syndrome in both sexes points to an autosomal recessive trait.

Bilateral parotid duct fistula. Case report.
Parotid duct fistulas (PDFs) are rare and have various causes such as gunshot wounds and human and animal bites; they may also be congenital. We have not found previous publications on bilateral PDF. Our patient, although young, also had generalized pigmentation characteristic of aging and thick, dry, wrinkled skin, as well as pyoderma. Biochemical analysis was performed on discharge from the patient's face, and histopathologic and immunologic studies were done. The fistulas were treated by intraoral fistulization. Cephalosporins were given to the patient for 5 days postoperatively to treat the pyoderma.

Two-day induction with thymoglobulin in kidney transplantation: risks and benefits.
INTRODUCTION: The aim of this study was to develop an induction protocol to reduce allograft rejection with fewer posttransplant infections and malignancies. METHODS: In this prospective randomized study, a T- and B-cell depletion protocol, consisting of IV thymoglobulin (ATG 5 mg/kg/d) plus methylprednisolone (500 mg/d) plus azathiopurine (2 mg/kg/d), was on days 0 and 1 after renal transplantation. CyA was introduced at day 3.39 among patients undergoing either primary living related (n = 16) or cadaveric (n = 23) transplants excluding recipients of full-HLA-matched sibling, or five- and six-HLA-matched cadaveric donor kidneys. The adequacy of immunosuppression was evaluated by flow cytometric analysis for total, CD3+ (T-cell), and CD19+ (B-cell) lymphocytes. RESULTS: The acute rejection rate was 6% and 37/39 patients are alive with functioning grafts at an average follow-up of 14.5 months. The overall patient and graft survival rate was 95%. Their mean creatinine value was 1.27 mg/dL. Six patients (16%) required hospitalization due to serious infections. The two deaths were attributed to septicemia and brain abcess caused by unusual agents, namely, Rhodococcus equi and Sporobolomyces. One patient presented with a cutaneous Kaposi sarcoma in the 11th month posttransplant. CONCLUSION: A Two-day induction protocol with thymoglobulin yields acceptable acute rejection rates among renal transplants. However, caution is necessary for adverse events, particularly atypical bacterial and fungal infections.
