Perinatally acquired Chlamydia trachomatis associated morbidity in young infants.

OBJECTIVE: This study was designed to evaluate the spectrum of morbidity associated with perinatally acquired Chlamydia trachomatis in infants < or =12 weeks of age, and to determine its relationship to maternal Chlamydia trachomatis status. METHODS DESIGN: Retrospective review of maternal and infant records. SETTING: Large inner city teaching hospital. PATIENTS: A cohort of 530 symptomatic infants < or =12 weeks of age who were tested for Chlamydia trachomatis infection in the upper respiratory tract during a 2-year period from January 1993 to December 1994. RESULTS: During the study period, 70/530 (13.2%) patients tested positive for Chlamydia trachomatis from the conjunctiva and/or the nasopharynx. Complete medical records of 66 of these infants were available for review. Forty-eight of 66 (73%) infants had conjunctivitis, 13/66 (20%) had pneumonia, 5/66 (7%) had both conjunctivitis and pneumonia. Thirteen of 66 (20%) infants were hospitalized, 7 for pneumonia and 6 for ophthalmia, accounting for 68 hospital days. In 55/66 (83%), maternal records were available for review. Nineteen of 55 (35%) mothers had documented Chlamydia trachomatis infection at delivery or during pregnancy that had not been treated; 16/55 (29%) mothers tested negative for Chlamydia trachomatis sometime during pregnancy but were not retested at delivery, 8/55 (14%) were treated for Chlamydia trachomatis during pregnancy but status at delivery regarding reinfection was not evaluated. In 12/55 (22%) mothers, no prenatal testing was documented. CONCLUSIONS: This study demonstrates significant morbidity in early infancy associated with perinatally acquired Chlamydia trachomatis infection. There is need for studies evaluating the importance of adequate maternal testing and treatment to reduce perinatal transmission.

Mother surrogate and nutritional status of preschool children.

The study was conducted on 200 preschool children to find out the effect of mother surrogate on the nutritional status. The nutritional status of children was found to be affected by the time devoted by mother on child care activities, working status of mother and type of family independently and jointly. The children cared by mother had better nutritional status than those children who were cared by servants and any other family member in the absence of mother. It shows that no one can substitute the care provided by the mother.

Oral clonazepam sensitive focal status epilepticus (FSE).

Focal status epilepticus (FSE) and Epilepsia partialis continua (EPC) are relatively uncommon disorders. Antiepileptic drugs do not usually alter the FSE-EPC. An 11 year old female patient with progressive neurologic deficits and FSE showed a remarkable response to clonazepam, both clinically and electrophysiologically.

Hepatic function in hypothermically stored porcine livers: comparison of hypothermic machine perfusion vs cold storage.

Hypothermic machine perfusion (HMP) has a potential to relieve the current donor liver crisis by providing an improved and extended preservation method. This study examined the effect of HMP on hepatocellular functions, using a prototype liver transporter capable of preserving livers for 24 hours. Livers obtained from adult farm pigs (28 to 32 kg body weight) were divided into three groups: fresh control, HMP, and simple cold storage (n = 4 each). A 4-hour normothermic reperfusion of livers was conducted to assess hepato-metabolic and cellular functions. The hepatic transport function, as indicated by canalicular excretion of indocyanine green, was improved in the HMP group than in the SCS group. The overall tissue viability, as indicated by oxygen consumption levels, was notably improved in HMP and control livers as compared to the SCS group. Higher bile production in both the preserved groups as compared to the fresh control livers could be a result of biliary edema and leakage of plasma into the canaliculus. The hepato-cellular injury, measured by ALT, release was significantly greater in the SCS group as compared to the HMP and control groups. These findings suggest that HMP could be a better method to preserve hepatic function and overall tissue viability as compared to SCS. Improved hepatic functions are indirect indicators of superior microcirculation and sinusoidal endothelial cell functions. Further studies in progress will evaluate these functions to confirm the significance of these observations.

Success of monovision in presbyopes: review of the literature and potential applications to refractive surgery.

The monovision concept of correcting one eye for distance and the other for near may be utilized in presbyopes undergoing refractive surgery. We have performed a systematic review of published literature to evaluate the factors influencing monovision success, and to determine the visual outcome in patients with monovision. Articles in MEDLINE and published bibliographies reporting monovision prescription for correction of presbyopia were systematically identified and reviewed. Pertinent data were abstracted and, when feasible, statistically analyzed. The mean success rate was 73%. The success in monovision correlated with distance correction on dominant eye, alternating dominance, less than 50 seconds of are stereoacuity reduction, and less than 0.6 prism diopter of distance esophoric shifts. Monovision resulted in significant reduction of binocular contrast sensitivity function at spatial frequencies higher than 4 cycles per degree, and 2-6% reduction in task performance, but resulted in minimal reduction of binocular visual acuity, peripheral vision, visual field width and binocular depth of focus. The published literature indicates that monovision is an effective and reasonable therapeutic modality for correcting presbyopia. Proper patient selection and clinical screening are essential for monovision success.

Chronic bilateral suppurative otitis media caused by Aspergillus terreus.

A case of bilateral suppurative otitis media is described in a patient with the presenting symptoms of otorrhoea, itching, mild deafness, heaviness in the ear and otalgia. The patient had perforation in the tympanic membrane. Histological sections revealed aggregated fungal masses of Aspergillus terreus. The infection responded well to topical ketoconazole therapy. Incidentally, this is the second case from India of chronic suppurative otitis media caused by fungi.

Effect of phenytoin on semen.

Male patients receiving antiepileptic drugs (AEDs) have often complained of hyposexuality. Few studies have been done on semen analysis, which is relevant for assessment of potential and possible reproductive outcome in such cases. We evaluated the effect of epilepsy itself and/or phenytoin (PHT) on the male reproductive system. Fifty-five patients with epilepsy (42 with PHT and 13 untreated) and 28 healthy normal controls were studied by semen analysis. Serum samples from 21 of the 55 patients were also analyzed for testosterone, luteinizing hormone (LH), and follicle-stimulating hormone. Results showed lower volume of seminal fluid, spermatozoa concentration, and total sperm count in untreated and PHT-treated patients as compared with controls, although no difference was evident between the patient groups. Morphologically abnormal sperm were more increased in untreated patients than in PHT treated and control subjects. Hormonal analysis showed lower levels of testosterone in 9 patients. LH levels were increased in one third of the patients. Our results suggests an effect of seizures on the male reproductive system, and PHT may have a slight additive (if any) influence.

Gabapentin in refractory partial epilepsy--a trial in India.

Gabapentin (GBP) has been shown to be effective an add-on drug for the treatment of refractory partial epilepsy. We undertook an open clinical trial to test its efficacy for the first time in India. Twenty-six patients with refractory partial seizures (> 4 per month) were given GBP in a titrated dose and the seizure frequency was noted for 3 months. The mean reduction in seizures was significant: 15.87 (SD = 4.5) vs 5.80 (SD = 10.25). The mean percentage change (PCH) from the baseline was -36. Twenty-one of 26 (80%) patients had a reduction in the number of seizures, and 13/26 (50%) were identified as responders (> 50% reduction in seizures). The responders were significantly younger than the nonresponders. Adverse events were mild and noted in 46% patients. Although the trial has its limitations, this is probably the first trial of GBP in a developing country.

Molluscum contagiosum. A case report with fine needle aspiration cytologic diagnosis and ultrastructural features.

BACKGROUND: Cytomorphologic and ultrastructural features of molluscum contagiosum, a rare skin lesion of viral etiology, are presented. CASE: A 4-month-old female was referred for fine needle aspiration cytology of papules over the back and chest wall. A Giemsa-stained preparation of whitish material aspirated from the chest wall nodule showed numerous large, intracytoplasmic, basophilic bodies that pushed the host cell nucleus to the periphery, giving a signet-ring appearance to a few cells. A cytologic diagnosis of molluscum contagiosum was suggested. On electron microscopy numerous intracytoplasmic viral particles were demonstrated, thus confirming the cytologic diagnosis. CONCLUSION: In clinically unsuspected cases, the cytologic diagnosis of molluscum contagiosum can be suggested by demonstrating pathognomonic molluscum bodies in aspirated material.
