Chlamydia trachomatis among HIV infected patients using PCR technique

Background and Objectives: Chlamydia trachomatis is a sexually transmitted organism and an important public health problem in the sexually active age group. Limited studies are found regarding the prevalence of Chlamydia trachomatis in Nepal. Moreover, no study in Nepal reports the association of Chlamydia and HIV infection. The current study attempts to determine the burden of Chlamydia on HIV positive patients. Material and Methods: A total of 117 HIV positive patients visiting a HIV clinic in Kathmandu, were screened for Chlamydia infection. For this, Urine samples were collected and analyzed using the Multiplex polymerase chain reaction technique (MPCR) and Agarose gel electrophoresis. DNA isolation was performed using QIAamp DNA and Blood mini kit handbook protocol. Results: C. trachomatis was detected in 4.27% of the total 117 HIV patients. Out of positive cases 60% were males and 40% were females. However, Chlamydia is found more prevalent among females (6.89%) than in males (3.4%). Eighty percent of positive cases were asymptomatic. Conclusion: Chlamydia infection was found less commonly among studied patients and most of those cases were asymptomatic. So there is difficulty in timely detection of C. trachomatis and track the clinical sequel, which might be devastating. Hence, routine checkup is recommended for all suspected cases for timely management of the disease.

Bony hydatid disease of superior pubic ramus with extension into pelvis and proximal thigh.

Hydatid disease is caused by the tapeworm of genus ;Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis. Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease can take place either directly through ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%), followed by the lungs (18-35%). Bone hydatidosis however is very rare,whenever it occurs; it is usually secondary to visceral involvement. We present herein a case of primary hydatid cyst involving superior pubic ramus in a 43 years male patient, which is not a common site for the occurrence of this disease. Diagnosis is usually delayed if high index of suspicion is not there. MRI is a good tool for reaching diagnoses.

Outcome of supracondylar fractures of the humerus in children treated by closed reduction and percutaneous pinning.

Supracondylar fractures of humerus in children are common injuries. Displaced fractures are inherently unstable. Conservative treatment results in malunion. Open reduction and internal fixation (ORIF) is more invasive and recovery is prolonged. From September 2004 to September 2005, 102 displaced supracondylar fractures of humerus, aged between one and half year to 13 years, were treated using close reduction and percutaneous Kirschner (K) wire fixation under c-arm fluoroscopy. Seventy nine patients were treated by cross K-wires and in twenty three cases lateral two K-wires were put. Above elbow plaster of paris back slab was applied in all cases for at least four weeks. Back slab, K-wires were removed after four weeks and elbow range of motion exercise was started. Results were analyzed using Flynn's criteria. All patients were followed up to 14th week postoperatively. In cross K-wire group(N=79) 70.8% had excellent, 22.7% good, 3.8% fair and 2.5% had poor results at eight weeks follow up which was improved to 91.1% excellent, 6.3 good, 1.2% fair and 1.26% poor results at 14 weeks follow up. In lateral K-wire group (N=23) 70% had excellent, 21.7% good, 4.3% fair and 4.3% had poor result at eighth week which was improved to 91.3% excellent, 4.3% good, 4.3% fair and no poor result at 14th week follow up. Eight patients got superficial pin tract infection and seven patients sustained ulnar nerve injury post operatively. We recommend this procedure for displaced supracondylar fractures in children as it is safe and cost effective procedure with acceptable complication rates.

Clinical profile and antibiotics response in typhoid fever.

OBJECTIVE: The objective of this study is to evaluate the clinical profile and drug response in typhoid fever. METHODS: This is a retrospective analysis of paediatric patients suffering from typhoid fever who were admitted at Kathmandu Medical College Teaching Hospital, Sinamangal during the period of two years and nine months. RESULTS: Total numbers of 100 cases of typhoid were studied. Diagnosis of Typhoid fever was based on clinical features, Widal test and blood culture. The sensitivity pattern of drugs in blood culture was recorded. The mode of presentation, treatment history, laboratory investigations reports, antibiotics administered and response to therapy were recorded. CONCLUSION: Quinolone is still the highly sensitive drug and most widely used for Salmonella typhi. Because of the indiscriminate use of these drugs, resistant to ciprofloxacin has been quite high and the duration of the defeverscence period has also been prolonged. But Ofloxacin is still showed highly effective and widely used with good response.

Leech therapy for complicated varicose veins.

Several methods of limb bandaging have been described to reduce the oedema and enhance ulcer healing in complicated varicose veins, with varying success rates. Leech therapy has never before been tried for the same. We evaluated the effectiveness of medicinal leech therapy in producing venous decongestion, reversal of oedema, hyperpigmentation and healing of varicose ulcer(s). Whether the leech selectively sucks venous blood was also investigated. Hirudo medicinalis (medicinal leech) was applied to the area surrounding the varicose ulcer(s) in 20 patients with varicose veins with complications and the patients monitored for ulcer healing, and decrease in hyperpigmentation, oedema and limb girth. The partial pressure of O2 (pO2) of 7 patients' arterial and venous blood was compared to that sucked by the leech. After leech therapy all the ulcers showed healing, while 95 per cent of patients showed a decrease in oedema and limb girth. Seventy five per cent patients demonstrated a decrease in hyperpigmentation. The mean pO2 of blood sucked by the leech was 40.05 +/- 7.24 mmHg, which was similar to the mean pO2 of the patients' venous blood (34.33 +/- 8.4 mmHg). Thus it appears from this study that the medicinal leech sucks venous blood and aids ulcer healing, and can probably therefore be used as an effective adjunct in the management of complicated varicose veins. This however requires further evaluation by controlled trials.

Adult intrahepatic solitary choledochal cyst.

A 20-year-old woman presented with dull ache in the abdomen. Ultrasonography and CT scan showed a solitary liver cyst. Roux-en-Y cystojejunostomy was done since there was bile in the cyst. Histology of the cyst wall revealed it to be a choledochal cyst. Solitary intrahepatic choledochal cyst and presentation in adult life are rare.

Colonic chemobezoar--intestinal obstruction due to barium inspissation.

A 72-year-old man presented with constipation of 45 days' duration, with history suggestive of recurrent episodes of subacute intestinal obstruction relieved by passage of fluid and flatus; he had noticed an abdominal lump 30 days prior. Examination revealed a lump corresponding to the contours of the entire large intestine. X-ray showed barium outlining the colon. Enquiry revealed that he had undergone a barium enema study 10 days prior to appearance of the lump. The diagnosis of barium inspissation was confirmed at laparotomy; total colectomy with ileo-rectal anastomosis was done.
